    Description

    TECHNICAL FIELD



    [0001] The present disclosure relates to the aerostat technical field, and specifically, relates to an exhaust assembly for an aerostat, and an aerostat installed with the exhaust assembly.

    BACKGROUND



    [0002] Aerostats generally include balloons and airships. A shaped aerostat lifts off from the ground. As a flight height increases, external air density and atmospheric pressure gradually decrease, and a volume of lifting gas inside the aerostat expands rapidly. For the sake of safety and to maintain an aerodynamic configuration of the aerostat, some gas in the aerostat needs to be exhausted, to adjust a difference between the internal and external pressure to a specific range. The range is determined by a material strength, a flight strategy, and an aerodynamic parameter. Even if the aerostat is anchored on the ground or flies at a specific height, gas in the aerostat also expands as an ambient temperature increases. In this case, some gas needs to be exhausted. Otherwise, a body of the aerostat cracks due to excessive pressure. Therefore, the aerostat needs an exhaust apparatus to maintain the difference between the internal and external pressure within the specific range when being anchored on the ground, lifting off after taking shape, and floating in the air.

    [0003] A conventional exhaust valve includes a valve body, a valve cover, a spring, and a pull rod. The valve cover of the exhaust valve is closed by using elastic pull force of the spring. When pressure of gas in the aerostat increases, a force of the internal pressure on the valve cover is greater than preset elastic pull force of the spring, and the valve cover is opened, to exhaust gas; then, the internal pressure decreases, and the valve cover is closed under the action of the spring; and so forth. Using this type of exhaust valve mainly brings the following problem: passive control, lacking flexibility. This is because the valve cover is of a pure mechanical structure, and it relies solely on an action of the spring and the internal atmospheric pressure to open or close the valve cover. When the atmospheric pressure is large, the valve cover is opened; and when the atmospheric pressure is small, the valve cover is closed. The valve cover cannot be actively controlled to open or close, lacking flexibility and resulting in a narrow range of application.

    [0004] CN105065685A discloses a single-bar zero-friction butterfly valve with a guide groove. The butterfly valve comprises a valve body, a guide plate, a valve shaft, a guide shaft, a connection plate, a butterfly plate, two linkage rods and a drive motor, wherein the valve body is of a hollow cylinder structure, a seal ring is disposed in a circumferential direction of the valve body, one end of the guide plate is fixed on an inner wall of the valve body while the other end of the guide plate is provided with the guide groove, the linkage rods are arranged at two ends of the guide plate, the valve shaft is of a cylinder-shaped structure and penetrates the guide plate and fixing through holes in the linkage rods, two ends of the valve shaft are fixed on the valve body, the drive motor is fixed at an outer wall of the valve body, a rotor of the drive motor is fixedly connected with one end of the valve shaft, the main body of the guide shaft penetrates through moving through holes in the linkage rods and the guide groove on the guide plate, fixed terminals are fixed on the connection plate, the connection plate is vertically fixed on the butterfly plate, and the butterfly plate and the seal ring are in sealed coordination. The single-bar zero-friction butterfly valve is simple in structure and wear-resistant, zero friction of the butterfly valve is realized, and the service life is prolonged.

    [0005] US5106052A discloses a damper for controlling air flow through an air duct. The damper includes a mounting fame secured to the interior of the duct which has a circular opening for air flow therethrough when the damper is open. A circular damper plate is provided which is dimensioned to block the circular opening in the closed position while in the fully open position the plate is rotated approximately 90 degrees where it is parallel to the flow direction through the duct. The movement of the damper plate is controlled by an actuator mechanism having a pair of spaced guide plates each of which is provided with two diverging arcuate guide slots. Corresponding guide slots in the two plates are aligned at the same vertical height. A movable support bracket is disposed between the two plates and supports two guide pins which extend horizontally through the aligned slots. The front end of the support bracket is rigidly secured to the damper plate and the back end is secured to a piston shaft coupled to a pneumatic cylinder. The movement of the guide pins in the diverging portion of the guide slots causes the damper plate to rotate while the rate of divergence is sufficient such that when the support bracket is urged forward by the cylinder the guide pins each undergo retrograde motion at different relative positions within the slots. This retrograde motion permits a short piston stroke to be used in addition to increasing the response time of the damper.

    [0006] US2003/136930A1 discloses an amplifying linkage for rotational actuation between a driving shaft and a driven shaft wherein the driving shaft rotates through a first rotary angle and the driven shaft rotates through a second and different rotary angle. The driven shaft is provided with a first lever arm having a slot formed in its distal end, and the driving shaft is provided with a second lever arm having a pin protruding in a direction parallel to the axis of the driven shaft. The shafts are offset such that the pin is receivable and slidable in the slot. Rotation of the driving shaft through a first angle causes the driven shaft to be rotated through a second angle. The first lever arm is shorter than the second lever arm, so that the second angle is always greater than the first (angular rotation is amplified). The invention is particularly useful in adapting a four-pole torque motor to the actuation of an Electric Throttle Control throttle valve for an internal combustion engine.

    [0007] CN103711977A discloses a gas exhaust device for an aerostat. The gas exhaust device comprises a valve. The valve comprises a valve body and a valve cover, wherein the valve body is provided with a valve port, and the valve cover covers the valve port in an openable and closable mode. The valve body is fixed to a gas suction and exhaust port of a gas bag in the circumferential direction of the gas bag of the aerostat through a valve body installing mechanism, wherein the valve cover covers the valve port in the openable and closable mode through a control device with an opening and closing device. The opening and closing device comprises a drive mechanism and a valve cover reset mechanism, wherein the drive mechanism is connected with the valve cover and used for driving the valve cover to be vertically lifted at a preset height and driving the valve cover to tilt and be kept at a certain angle after the valve cover is vertically lifted at the preset height. The valve cover reset mechanism is connected with the valve cover and pushes the valve cover to reset to cover the valve port after the drive mechanism stops driving the valve cover. The valve cover can be vertically lifted and can tilt at the same time, the gas exhaust area is increased, collision between gas and the valve cover is reduced, and the gas exhaust speed is increased.

    BRIEF DESCRIPTION OF DRAWINGS



    [0027] 

    FIG. 1 is an isometric view of an exhaust assembly, in which a valve cover is opened, according to an embodiment of the present disclosure; and

    FIG. 2 is an isometric view of the exhaust assembly, in which the valve cover is closed, according to the embodiment of the present disclosure.


    DESCRIPTION OF EMBODIMENTS



    [0028] Specific embodiments of the present disclosure are described with reference to the accompanying drawings. FIG. 1 and FIG. 2 respectively show isometric views of an exhaust assembly, in which a valve cover 3 is opened and valve cover 3closed according to embodiments of the present disclosure.

    [0029] In an embodiment shown in FIG. 1, an exhaust assembly for an aerostat includes a valve base 2 and a valve cover 3. The valve base 2 has a circular valve port 1. A shape of the valve cover 3 is corresponding to that of the valve port 1. The valve cover 3 can cover the valve port 1. The exhaust assembly further includes a motor driving mechanism and a transmission mechanism that are arranged on the valve base 2. The motor driving mechanism propels the transmission mechanism to drive the valve cove 3 to selectively cover the valve port 1. That is, when the exhaust assembly needs to exhaust gas, the motor driving mechanism drives, by using the transmission mechanism, the valve cover 3 to open; and when gas exhausting is completed, the motor driving mechanism drives, by using the transmission mechanism, the valve cover 3 to cover the valve port 1, thereby implementing valve closure. Further, when the valve cover 3 is in a position where the valve port 1 is open, the valve cover 3 is arranged at an angle with respect to a plane at which the valve port 1 is located. That is, in a process in which the valve cover 3 switches from the position where the valve port 1 is closed to the position where the valve port 1 is opened, the valve cover 3 goes through a rotation process, which is different from the prior art in which only a linear rise-and-fall process exists. Therefore, adjustment of the valve cover 3 in the present disclosure is more flexible.

    [0030] It should be noted herein that the motor driving mechanism driving, by using the transmission mechanism, the valve cover 3 to selectively cover the valve port 1 may be implemented in multiple manners. According to the invention, a motor fixed on the valve cover 3 is used to transmit, by using an output shaft 5, driving force to a shifting fork 6 connected to the output shaft 5, to drive the shifting fork 6 to rotate; then the shifting fork 6 drives, by using a interlocking shaft 71 that is connected to the valve cover 3, the valve cover 3 to move, thereby implementing opening and closing of the valve cover 3. For another example, not being part of the present invention, a telescopic rod can be located on two sides or in the middle of the interlocking shaft 71, instead of the shifting fork 6. This may also implement opening and closing of the valve cover 3. Alternatively, and also not being part of the present invention, an electromagnet may be used to control opening and closing of the valve cover 3. In comparison with the prior art in which a pure mechanical structure relies solely on an action of a spring and internal atmospheric pressure to open or close a valve cover, in the exhaust assembly in the present disclosure, the motor is used to drive the valve cover to open or close, thereby ensuring that exhausting pressure can be automatically and flexibly adjusted.

    [0031] Preferably, in the embodiments shown in FIG. 1 and FIG. 2, as optimally shown in FIG. 2, when the valve cover 3 is in a position where the valve cover 3 covers the valve port 1, that is, when atmospheric pressure in a balloon of an aerostat is appropriate, gas does not need to be exhausted, and the valve cover 3 is closed, a plane at which the valve cover 3 is located is parallel to the plane at which the valve port 1 is located. It may also be understood that the valve cover 3 is parallel to the valve base 2 when the valve cover 3 is at a closing location. As optimally shown in FIG. 1, when the valve cover 3 is in a position where the valve port 1 is open, that is, when atmospheric pressure in the balloon of the aerostat is too high, gas needs to be exhausted, and the valve cover 3 is opened (excluding statuses of the valve cover 3 during a process of moving from the closing location to a final opening location), a plane at which the valve cover 3 is located is vertical to the plane at which the valve port 1 is located. It may also be understood that the valve cover 3 is vertical to the valve base 2 when the valve cover 3 is at the final opening location.

    [0032] In comparison with the present disclosure, in a valve in the prior art, the valve cover and a screw rod are securely connected to each other, and the valve cover and the screw rod can do a straight motion only, that is, can rise and fall vertically (perpendicularly) only. Therefore, the valve cover has a certain blocking effect on the outflow gas when an exhaust apparatus opens the valve cover, thereby slowing down a gas exhausting speed. However, in the embodiments of the exhaust assembly of the present disclosure, when the valve cover is opened for exhausting gas in the aerostat, the plane at which the valve cover is located is vertical to the plane at which the valve port is located, so that outflow gas is not blocked, thereby improving exhausting efficiency.

    [0033] Specifically, as shown in FIG. 1, the motor driving mechanism includes a motor 4. The motor 4 has an output shaft 5 that is connected to the transmission mechanism, and the output shaft 5 is configured to transmit movement energy from the motor to the transmission mechanism.

    [0034] In the embodiment shown in FIG. 1, the transmission mechanism of the exhaust assembly includes: a shifting fork 6 connected to the output shaft 5, where the shifting fork 6 rotates when driven by the output shaft 5; a first interlocking shaft 71 that is connected to the valve cover 3 by using a connection shaft 8 arranged in the center of the valve cover 3, where two ends of the first interlocking shaft 71 is slidably arranged in a guide slot of the shifting fork 6; and a sliding slot 9 that guides the first interlocking shaft 71 to drive the valve cover 3 to switch between the opening location and the covering location.

    [0035] Specifically, the sliding slot 9 may be arranged in a sliding slot base 12. As shown in FIG. 1, the sliding slot base 12 may be an independent component, and may be installed on a location on two sides of the valve port 1 on valve base 2. In addition, two sliding slot bases 12 arranged on the two side of the valve port 1 are parallel with each other. Alternatively, the sliding slot base 12 extends from the valve base 2 to a side on which the motor 4 is arranged, and is integrally formed with the valve base 2.

    [0036] In a preferred embodiment, the sliding slot 9 is configured as an L-shaped sliding slot structure. That is, the sliding slot 9 has two slots whose extension directions are approximately perpendicular. In addition, the extension direction of one of the slots is vertical to the plane at which the valve port 1 is located, and the extension direction of the other one of the slot is parallel to the plane at which the valve port 1 is located. More preferably, to make the interlocking shaft slide more smoothly in the sliding slot 9, a round chamfer is provided in a position where the two slots of the L-shaped sliding slot structure intersect. It should be noted herein that although in this embodiment, although the sliding slot 9 is configured as an L shape, other shapes of the sliding slot 9, such as a circular arc, that can achieve a same effect are also applicable to the present disclosure, and need to be determined according to an actual situation. The present disclosure is not limited thereto.

    [0037] According to the invention, the exhaust assembly further includes a second interlocking shaft 72 associated with the first interlocking shaft 71. The "association" may refer to that the second interlocking shaft 72 may always maintain synchronous movement as the first interlocking shaft 71. Preferably, the second interlocking shaft 72 is also motionless relative to the first interlocking shaft 71 while maintaining synchronous movement as the first interlocking shaft 71. The second interlocking shaft 72 is arranged in a position between the first interlocking shaft 71 and the valve cover 3, and the connection shaft 8 connected to the first interlocking shaft 71 and the valve cover 3 extends through the second interlocking shaft 72. In other words, the connection shaft 8 passes through and connects the first interlocking shaft 71, the second interlocking shaft 72, and the valve cover 3 in sequence.

    [0038] The connection shaft 8 may connect the first interlocking shaft 71 and the valve cover 3 as an independent component in a form in which a nut and a screw coordinate. Specifically, the connection shaft 8 may include a screw and a nut. The screw passes through the first interlocking shaft 71 and the valve cover 3 in sequence, and the nut is threadedly connected to the screw so that the first interlocking shaft 71 and the screw are securely connected. Alternatively, the connection shaft 8 may be integrally formed with the valve cover 3, and formed by extending from a central location of the valve cover 3.

    [0039] Preferably, an O-shaped sealing ring 10 is arranged on an outer periphery of the valve cover 3. More preferably, the O-shaped sealing ring 10 is a metal sealing ring. In comparison with the present disclosure, in the prior art, a valve cover is sealed by using a sealing pad, preset force of a spring is relatively small compared to sealing pressure and is unstable. Therefore, sealing performance cannot be ensured. When pressure of a balloon is close to the preset force of the spring, a sealing effect is poor, and precision of the spring is low in repeated use. This is unfavorable for overall arrangement of pressure control. However, in the exhaust assembly in the present disclosure, when the valve cover is closed, the O-shaped metal sealing ring 10 on the outer periphery of the valve cover deforms after being squeezed by the valve port 1, thereby achieving a good sealing effect. In addition, the metal sealing ring may ensure sealing performance of the valve cover in repeated use and special environmental conditions such as low temperature.

    [0040] In addition, the motor driving mechanism in the exhaust assembly of the present disclosure may further include a decelerator connected between the motor 4 and the output shaft 5. The decelerator is configured to output an appropriate rotation speed to the output shaft 5.

    [0041] Moreover, in the exhaust assembly of the present disclosure, the valve base 2 is constructed in a flange-shaped structure. Multiple installation holes 11 are arranged at a same interval on an outer edge of the valve base 2 that is in a flange-shaped structure, and are configured to install the valve base 2 on an aerostat.

    [0042] In summary, in the embodiments of the exhaust assembly of the present disclosure shown in FIG. 1 and FIG. 2, a specific working process is as follows: To open the valve cover 3, the motor 4 works, the output shaft 5 drives the shifting fork 6 to rotate, the first interlocking shaft 71 does a straight motion, driven by the shifting fork 6, along the sliding slot 9, the second interlocking shaft 72 is simultaneously driven to do a straight motion in the sliding slot 9, and the valve cover 3 does a straight motion driven by the connection shaft 8, to depart from the valve port 1; when the first interlocking shaft 71 reaches a round chamfer segment of the sliding slot 9, the first interlocking shaft 71 and the second interlocking shaft 72 do a translational motion and rotate as a whole, to drive the valve cover 3 to do a translational motion and rotate; and when the first interlocking shaft 71 reaches a terminal of a horizontal straight line segment of the sliding slot 9, the valve cover 3 rotates to a location vertical to the valve base 2, the motor stops working, and the valve cover 3 is completely opened. The valve cover 3 is opened and closed in a similar way. The valve cover 3 does a translational and rotational motion under the action of the first interlocking shaft 71 and the second interlocking shaft 72; when the first interlocking shaft 71 and the second interlocking shaft 72 both reaches a vertical straight line segment of the sliding slot 9, the valve cover 3 becomes parallel to the valve base 2, and then does a straight motion; when the second interlocking shaft 72 reaches a terminal of the vertical straight line segment of the sliding slot 9, the O-shaped metal sealing ring 10 on the valve cover 3 is squeezed into the valve port 1, the motor 4 stops working, and the valve cover 3 is completely closed.

    [0043] Only preferred embodiments of the present disclosure are described above, and they are not intended to limit the present disclosure. For a person of ordinary skill in the art, the present disclosure may have various medications and changes. All modifications, equivalent substitutions and improvements without departing from the scope of the present disclosure are solely defined by the appended claims.
