BACKGROUND OF THE INVENTION
1. Field of the invention
[0001] The present invention relates to hydraulic buoyant force engine in particular, to
a mechanism which is capable of generating a mechanical driving power by circulation
of several expansion floats sinking down in the water or floating up on the water
level by discharging or absorbing the air.
2. Description of the Prior Art
[0002] The conventional power generation techniques such as utilization of water power,
steam, power or even neuclear power relies on natural resources of earth. In view
of rapid fading of natural resources, and loosing of ecological balance, unlimited
and environment unconscious exploitation of natural resources must be haulted for
the sake of human right of existence. Development of some sorts of low cost and clean
power generation means seems a matter of great urgency.
[0003] It is what the reason the inventor has endeavored for years by continuous research
and experimentation attempting to find out an ingenious and clean environment conscious
power generating technique, and finally has come out with the hydraulic buoyant force
engine of the present invention.
SUMMARY OF THE INVENTION
[0004] It is an object of the present invention to provide a hydraulic buoyant force engine
which can generate mechanical power without consuming any other resources.
[0005] It is another object of the present invention to provide a hydraulic buoyant force
engine which can be fabricated with a low production cost and operate with inexpensive
hydraulic buoyant force.
[0006] To achieve the above objects, the hydraulic buoyant force engine is essentially composed
of a track assembly and several expansion floats. The track assembly contains two
gourd shaped track ways forming in V shaped structure. Two (first and second) transmission
chains circulation railways are provided to each outer side thereof on which the expansion
floats are attached in equal spacing along the chains. The air gate of each float
is communicated in series with a connecting hose whose output terminal is communicated
with an air conducting tube laid on top side of the track assembly for absorbing or
discharging the air. When the track assembly is set in a water tank filled with water,
the air conducting tube emerges out of the water surface, the expansion float located
at the widely apart portion between the two gourd shaped track ways is expanded by
ingress of the air such that the buoyancy of the float overcomes its own weight. As
a result, the float rises upward along the track ways and causes the chains to move.
As soon as the expanded float approaches the narrowly apart portion between the two
track ways, it is squeezed by the track ways to release the air inside and sinks downward
along with the movement of the first and second chains due to loosing of its buoyancy.
In this way the chains at both sides of the track assembly keep continuous circulation
and the mechanical power is outputted from the output shafts of the chains.

on the hasps 123, 133, 143 respectively are to be fitted to the corresponding stoppers
121, 131, 141 so as to tie up the hasps 123, 133, 134 with the corresponding stoppers
121, 131, 141 by pressing down the hooks 122, 132, 142. The second and third hoops
13, 14 are engaged with guide vanes 135, 145 respectively, and both sides of the hoops
13, 14 are protected by braces 136, 146 respectively. Two braces 136, 146 are provided
with Reels 134, 147 respectively.
[0010] A supporting stand 15 including a supporting plate 151 is provided at the right end
of the float body 11 thereof. Two parallel slide arms 152, 153 are formed at both
sides of the supporting plate 151. The inner surfaces of the arms 152, 153 have corresponding
in position but different sized first reels 1521, 1531 and second reels 1522, 1532.
With this structure the supporting plate 151 can be engaged with two guide vanes 135,
145 of the second and third hoops 13, 14 so as to tighten the supporting stand 15
firmly with the second and third hoops 13, 14.
[0011] A first and a second guide bars 16, 17 whose central portions are respectly engaged
with two sides of the first hoop 12 so that the two guide bars 16, 17 are engaged
respectively with the front and rear sides of the float body 11, and their both ends
perforate the braces 136, 146 laid at both sides of the second and third hoops 13,
14 such that the float body 11 may expand or shrink along the first and second guide

the aid of the reels 137, 147 provided at the sides of the braces 136, 146. The guide
bars 16, 17 are hollow and have inner threads 161, 171.
[0012] Two first joint plates 18 each with two tapped holes 181, 182 (see Fig. 1) are provided.
The two joint plates 18 are jointed to both ends of the first guide bar 16 and engaged
with screws 10 by aligning the tapped holes 181, 182 with both ends of the first guide
bar 16.
[0013] Two second joint plates 19 each provided with a tapped hole 191,192 respectively
engaged with screw 10 to each end of the second guide bar 17 by aligning the hole
191 with the ends of the second guide bar 17.
[0014] Referring to Fig. 2, the drawing shows the schematic view of the transmission mechanism
of the present invention. The transmission mechanism includes a track assembly 2,
an air conducting tube 3, two output shafts 51, 52, two chain 61, and two circulation
railways 62.
[0015] The track assembly 2 is composed of two gourd shaped track ways 21, 22 forming in
V shaped structure, and are secured by a framework 23.
[0016] The air conducting tube 3 has an air gate 31 at its proper position thereof. The
air conducting tube 3 is perforating near the top portion of the track assembly 2
and emerges its both ends out of the track assembly 2. There are two pairs of first
and second sprockets 41, 42 fitted to the air conducting tube 3 firmly from two outersides
of the track assembly 2.
[0017] The two output shafts 51, 52 are each coupled with the corresponding one of the third
and fourth sprockets 43, 44 by perforating themselves through bottom portion of the
two trackways 21, 22 thereafter the first and the third sprockets 41, 43, and the
second and the fourth sprockets 42, 44 are respectively aligned with each other thereby
remaining a disconnected section 53 between the two output shafts 51, 52.
[0018] A first and a second chains 61, 62 are each provided with at least one support strap
611, 621 with tapped hole 6111, 6211. The first chain 61 is coupled with the first
and third sprockets 41, 43 while the second chain 62 is coupled with the second and
fourth sprockets 42, 43 therfore both outersides of the track assembly 2 are enseized
by the chains 61, 62.
[0019] Each of the two circulation railways 62 are respectively welded to the framework
23 at both sides of the trackassembly 2 so as to secure each circulation railway 62
firmly between the track assembly 2 and the chain 61:
[0020] Referring to Figs. 3 and 4, the first joint straps 18 at the both sides of the float
body 11 are engaged to the joint plates 621 of the second chains 62 with screwing
or welding by aligning tapped holes 182 with tapped holes 6211 of the joint straps
621 of the second chains 62 such that the float body 111 is firmly engaged with the
chains 62 via joint straps 621. By similar way, by screwing or welding after aligning
the tapped holes 192 of the second joint plates 19 with the tapped holes 6111 of the
joint straps 611 of the first chain 61, the float body 111 can be firmly engaged with
the first chains 61 via second joint plate 19. In this way the float body is set between
the first reels 1521, 1531 and the second reels 1522, 1532 of the stand 15 to let
the float body 11 circulate along the track ways 21, 22.
[0021] Referring to Fig. 5, in this side view of the present invention, several expansion
floats 1 are disposed between the chains 61. One of the floats 1 has a four way coupling
81 jointed to its air gate 112, while the rest of the floats 1 are each provided with
a three way coupling 82. All the air gates 112 are linked together with a hose 9 so
that all expansion floats 1 can be communicated with one another. Finally, the output
terminal of the hose 9 is connected to the air conducting tube 3 via four way coupling
such that the air can freely flow into or discharge out of the expansion floats via
the air tube 3. The hose 9 disposed in the disconnected section 53 between the output
shafts 51 and 52 at the bottom portion of the track assembly 2 is for preventing the
hose 9 from entangling with the nearby objects during movement of the float 1.
[0022] For understanding the operation of the present invention, reference should be made
to Figs. 6A and 6B. Before operation, the framework 23 of the track assembly 2 is
fixed in a water tank 6 to hold the track assembly 2 stationary at its position, and
emerg the air conducting tube 3 out of the water level 7 so as to communicate with
the outside air. When the expansion float 1 sinks under the water level 7 as shown
in Fig. 6a, the expansion float 1 located at the widely apart portion between the
track ways 21, 22 is expansible to let the air in via the tube 3 so as to build up
a buoyant force able to overcome its won weight and floats up. At this moment, being
activated by the buoyant force of the expansion float 1, the chains 61, 62 start circulation
which in turn activate other expansion floats 1, the first to fourth sprockets 41,
42, 43, 44 the air conducting tube 3, and the output shafts 51, 52 to operate. Since
the two track way 21, 22 are located between the first reels 1521, 1531 and the second
reels 1522, 1532 of the supporting stand 15, this causes the float 1 can move along
the two circulation railways with the sliding blocks 9 at its two sides thereof, and
the hose 9 connected to the air gate 112 at one side of the float 1 is crooked around
the tube 3 as shown in Fig.5. As soon as the expanded float 1 has passed over the
top portion of the track assembly 2 and reached down the narrowly apart portion between
the track ways 21 and 22, the hose 9 is straightened as shown in Fig. 6B. The expanded
float 1 is now gradually squeezed between the first and the second guide bars 16,
17 to release the air contained inside. The flattened float 1 now sinks down in the
water together with the first and second chains 61, 62 by its own weight. Each expansion
float 1 carries out this motion one after another along the track assembly 2, and
the first and second chains 61, 62 continue to drive the output shafts 51, 52 thereby
producing a useful mechanical power.
