The expansion cabin 2 and the expansion tent 3 are separately connected to the fixed cabin 1. Both the expansion cabin 2 and the expansion tent 3 can be folded. When completely folded, the expansion cabin 2 and the expansion tent 3 are located in the fixed cabin 1. When the expansion cabin 2 and the expansion tent 3 are unfolded, both the expansion cabin 2 and the expansion tent 3 communicate with the fixed cabin 1. An equipment room 17 and a central control area 19 are arranged in the fixed cabin 1. The expansion cabin 2 serves as a preparation room 15 and a PCR room 21. The expansion tent 3 serves as a core workroom 18 and a liquid preparation room 20. A buffer room 16 is arranged in each of the fixed cabin 1, the expansion cabin 2, and the expansion tent 3. The expansion tent 3 is in sealed connection with the fixed cabin 1. The expansion tent 3 is large in size after being unfolded, and serves as the core workroom 18 and the liquid preparation room 20, which increases the operation space.

[0024] According to the double-side expansion cabin type mobile nucleic acid detection laboratory of the present disclosure, both the expansion cabin 2 and the expansion tent 3 can be unfolded, and are located in the fixed cabin 1 after being folded, so the double-side expansion cabin type mobile nucleic acid detection laboratory has the advantages of small size after being folded and large operation area after being unfolded, thereby facilitating the transportation of the laboratory, and improving the flexibility and convenience of the double-side expansion cabin type mobile nucleic acid detection laboratory. It should be noted that, the fixed cabin 1 may be connected to a lifting device 4. The lifting device 4 can drive the fixed cabin 1 to ascend, descend, or move, so as to facilitate the movement and transportation of the fixed cabin 1.

[0025] The expansion cabin 2 includes a first base plate 5, a cabin body 6, and a bracket 7. The first base plate 5 is hinged to the fixed cabin 1. The cabin body 6 is connected to the first base plate 5. The cabin body 6 is made of a flexible material. The bracket 7 is connected to the first base plate 5 and the cabin body 6. When a relative angle between the first base plate 5 and the fixed cabin 1 changes, the bracket 7 can drive the cabin body 6 to move. The rotation of the bracket 7 can drive the flexible cabin body 6 to unfold and fold. The first base plate 5 is hinged to the fixed cabin 1. When the cabin body 6 is unfolded completely, the first base plate 5 is parallel to the ground, and when the cabin body 6 is completely folded, the first base plate 5 is flush with a side wall of the fixed cabin 1.

[0026] Specifically, the first base plate 5 is hinged to the bottom of the fixed cabin 1. The bracket 7 includes first connecting rods 701, a second connecting rod 702, first long support rods 703, and a second long support rod 704. One end of the first long support rod 703 is hinged to one end, far away from the fixed cabin 1, of the first base plate 5. The second long support rod 704 is connected to the top, far away from the fixed cabin 1, of the cabin body 6. The other end of the first long support rod 703 is hinged to one end of the second long support rod 704. One end of the first connecting rod 701 is hinged to the top of the fixed cabin 1, and the other end of the first connecting rod 701 is hinged to the first long support rod 703. A hinge point of the first connecting rod 701 and the first long support rod 703 is located between a hinge point of the first long support rod 703 and the second long support rod 704 and a hinge point of the first long support rod 703 and the first base plate 5. The second connecting rod 702 is connected to the top of the cabin body 6. One end of the second connecting rod 702 is hinged to the second long support rod 704. A hinge point of the second connecting rod 702 and the second long support rod 704 is located between a hinge point of the second long support rod 704 and the first long support rod 703 and a hinge point of the second long support rod 704 and the cabin body 6. A driving cylinder is arranged between the first base plate 5 and the fixed cabin 1. The driving cylinder pushes the first base plate 5. The first base plate 5 rotates around the fixed cabin 1 to drive the first long support rod 703 and the second long support rod 704 to rotate. The first connecting rods 701 and the second connecting rod 702 are respectively connected to the cabin body 6, the first long support rods 703 and the second long support rod 704 to drive the cabin body 6 to unfold. When the cabin body 6 is gathered, the driving cylinder drives the first base plate 5 to rotate. Under an acting force of the first base plate 5, the first long support rods 703 and the second long support rod 704 rotate and drive, together with the first connecting rods 701 and the second connecting rod 702, the flexible cabin body 6 to fold and be gathered in the fixed cabin 1. A second base plate 8 is overturned to be flush with the side surface of the fixed cabin 1.

[0027] In addition, there are two first long support rods 703 and two first connecting rods 701. Both the second long support rod 704 and the second connecting rod 702 are U-shaped rods. The two opposite ends of the second long support rod 704 are respectively connected to the two first long support rods 703. The two opposite ends of the second connecting rod 702 are respectively connected to the two opposite ends of the second long support rod 704. The bottoms of the second long support rod 704 and the second connecting rod 702 are separately connected to the cabin body 6. It should be noted here that the structure of the bracket 7 of the expansion cabin 2 of the present disclosure is not limited to the above structure. The bracket 7 shall be able to realize the folding and unfolding of the cabin body 6. In other specific implementation manners of the present disclosure, the bracket 7 is of a rhombus-shaped telescopic frame structure. The bracket 7 is connected to the top of the cabin body 6. When the second base plate 8 is overturned, the bracket 7 can drive the cabin body 6 to unfold and fold.

[0028] More specifically, the expansion tent 3 includes a second base plate 8, an inner tent 9, an outer tent 10, and a telescopic skeleton 11. The second base plate 8 is hinged to the fixed cabin 1. A driving cylinder is arranged between the second base plate 8 and the fixed cabin 1. The driving cylinder can drive the second base plate 8 to unfold. One end of the telescopic skeleton 11 is connected to the fixed cabin 1. The inner tent 9 is connected to the telescopic skeleton 11. The inner tent 9 is in sealed connection with the fixed cabin 1 to ensure the air tightness in the tent after the inner tent 9 is connected to the fixed cabin 1. The telescopic skeleton 11 can stretch and retract. The telescopic skeleton 11 can drive the inner tent 9 to move in the direction far away from the fixed cabin 1 and be tiled on the second base plate 8. After the second base plate 8 is unfolded, the telescopic skeleton 11 drives the inner tent 9 to unfold, the outer tent 10 is detachably connected to the inner tent 9. The outer tent 10 is additionally mounted after the inner tent 9 is unfolded. Both the inner tent 9 and the outer tent 10 are made of a flexible material. There is a gap between the inner tent 9 and the outer tent 10, which can achieve a heat insulating effect.

[0029] To improve the stability of the expansion tent 3, the expansion tent 3 further includes a support rail 12. The support rail 12 is arranged at the bottom of the fixed cabin 1 in a sliding manner. When the expansion tent 3 needs to be unfolded, first, the support rail 12 is pulled out. The second base plate 8 is located at the top of the support rail 12 after being unfolded. The support rail 12 can support the second base plate 8 to improve the stability of the expansion tent 3. In other specific implementation manners of the present disclosure, the expansion tent 3 may also be fixed by tent pegs and wind ropes, so as to further improve the structural strength of the expansion tent 3.

[0030] Further, to increase the use area of the expansion tent 3, the second base plate 8 is of a foldable structure. The second base plate 8 can be pressed against the support rail 12. The second base plate 8 includes two plate bodies. One end of one of the plate bodies is hinged to the fixed cabin 1. The opposite end of the plate body is hinged to the other plate body. The second base plate 8 adopts a split structure, so that the use area of the expansion tent 3 is increased without affecting the size of the laboratory after the expansion tent 3 is gathered, thereby improving the applicability of the laboratory.

[0031] In addition, the telescopic skeleton 11 includes a plurality of sliding frames. The plurality of the sliding frames is connected through rhombus-shaped telescopic frames. The inner tent 9 is arranged inside the sliding frames. Reciprocating movement of the sliding frames along the second base plate 8 can drive the inner tent 9 to fold or unfold. After the inner tent 9 is completely unfolded, the outer tent 10 is connected to the inner tent 9 for mounting, which improves the convenience in operation.

[0032] To improve the work efficiency when the telescopic skeleton 11 is unfolded and folded, pulley wheels 13 are arranged at the bottom of the sliding frames, a slide rail that is adapted to the pulley wheels 13 is arranged on the second base plate 8, which ensures the movement trajectory of the sliding frames. The pulley wheels 13 are arranged on the slide rail in a sliding manner, which prevents the dislocation of the sliding frames from affecting the work of the expansion tent 3.

[0033] Furthermore, the expansion cabin 2 and the expansion tent 3 are respectively arranged on the two opposite sides of the fixed cabin 1. The fixed cabin 1 lands onto the ground, and the expansion cabin 2 and the expansion tent 3 are folded, which improves the convenience in operation of the laboratory.

[0034] According to the double-side expansion cabin type mobile nucleic acid detection laboratory of the present disclosure, both the expansion cabin 2 and the expansion tent 3 can be unfolded, and are located in the fixed cabin 1 after being folded, so the double-side expansion cabin type mobile nucleic acid detection laboratory has the advantages of small size after being folded and large operation area after being unfolded, thereby facilitating the transportation of the laboratory, and improving the flexibility and convenience of the double-side expansion cabin type mobile nucleic acid detection laboratory. In the present specific implementation manner, the equipment room 17 and the central control area 19 are arranged in the fixed cabin 1. The expansion cabin 2 serves as the preparation room 15 and the PCR room 21. The expansion tent 3 serves as the core workroom 18 and the liquid preparation room 20. The buffer room 16 is arranged in each of the fixed cabin 1, the expansion cabin 2, and the expansion tent 3. A liftable mast is mounted outside the fixed cabin 1. A lighting device and a camera are mounted on the mast. The central control area 19 is arranged in the laboratory. A control system and a UPS are arranged in the central control area 19, where the UPS mainly supplies power to laboratory supply fans, exhaust fans, lighting, and instruments, equipment and control systems in the laboratory. In addition, a high efficiency filter is arranged at an exhaust outlet of the core workroom 18. A scanning leak detection and sampling device is arranged downstream of the high efficiency filter, which can realize in-situ leak detection of the high efficiency filter. Exhaust outlets are fitted in the buffer rooms 16, the PCR room 21, and the preparation room 15. High efficiency filters are arranged at the exhaust outlets. Exhaust pipelines are mounted in a side wall, and a downstream aerosol sampling port is mounted on a downstream pipeline of each high efficiency filter. The exhaust air of the core workroom 18, the buffer rooms 16, and the preparation room 15 is finally collected into an exhaust static pressure box. Two exhaust fans are mounted in the exhaust static pressure box. Air supply of the laboratory is supplied into each of the core workroom 18, the buffer rooms 16, the liquid preparation room 20, the PCR room 21, and the preparation room 15 after passing through a primary efficiency filter, a medium efficiency filter, an air conditioning unit, and a high efficiency filter. It should be noted that a communicating door is arranged between every two of the core workroom 18, the buffer rooms 16, the preparation room 15, and the equipment room 17. The arrangement of the communicating doors is a common method used by those skilled in the art, which will not be described in detail here.
