Abstract
Disclosed herein is a hydraulic buoyant force engine whose essential
component is a plurality of floats (1) engaged to two transmission
chains (6,7) of two sprocket and chain combination units each disposed
at either side of the floats. The float (1) is wrapped with a canvas
(14) supported by several rib units (13). When the float (1) is expanded
by air its buoyancy overcomes its own weight, floats up and drives the
chains (6,7) to move up. When the float comes up to a gear (8) above it,
a gear (17) will mate an annular gear rack (8) to act as an internal
spur gear unit so as to retract the rib units (13) thereby squeezing the
float (1) to discharge the contained air. The shrunk float sinks into
the water together with the two chains.
Description
- The present invention relates to hydraulic buoyant force engine, in particular, to a machine which is capable of operating to generate power exclusively driven by buoyancy.
- The conventional power generation can usually be classified into two categories, e,g. power generation by means of force of nature, such as hydraulic power and wind power, the other one is power generation consuming natural resources, such as neuclear power and steam power.
- However, there are some disadvantages inherent to the aforesaid modes of power generation.
- 1.Reliability of force of nature can not be expected up to 100%, abrupt variation of annual rainfall and frequency of typhoon cause the production of water power, and wind power can not be eagily controlled.
- 2.The production and maintenance cost for a neuclear or a steam power plant is usually quite expensive, and the rapid fading of natural resources in addition to loosing ecological balance applies a brake force to unlimited and unvironment unconscious exploitation of natural reforces that causes further development of neuclear power and steam power impossible.
- It is what the reason the inventor has endeavored for years by continuous research and experimentation attempting to find out an ingeniously unlimited and clean environment conscious power generating technique, and finally has come out with the hydraulic buoyant force engine of the present invention.
- It is an object of the present invention to provide a hydraulic buoyant force engine which can generate mechanical power without consuming any other resurces.
- 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 hydraulic buoyant force only without need for other expensive natural resources.
- To achieve the above objects, the hydraulic buoyant force engine of the present invention comprises a plurality of canvas enclosed floats each provided with an air inlet and an air outlet float up and sink down in a water tank along a central transmission bar by expanding and shrinking alternatively in accordance with the action absorbing the air into the float and releasing the air out of the float by means of an air guide unit connected to the float and emerged out of the water surface. The machenical power produced by motion of the floats is transmitted to an output shaft trough two sprocket and chain units each provided at one side of the floats so as to produce a continuous and restless mechanical power. The expansion and shrinkage of the float are performed by joint action of precisely designed gear mechanism and pivoted lever together with its actuation rod. Meanwhile, the water tank may be configurated in a L shaped polyhedron, or a regular polyhedron.

- Referring to Figs. 1, 2A and 2B simultaneously, in which a
float 1, the essential component of the present invention, and its expansion and shrinking states are illustrated. The component structure of thefloat 1 includes: -
transmission bar 11 erecting and piercing through the center of thefloat 1 and having two sections ofscrew threads 111 spiraled in opposite direction with respect to each other formed on the upper and lower portions respectively thereof; - two ball bearing
blocks 12 sleeved onto the upper and lower threadedportions 111 of thetransmission bar 11 and having a plurality of drilledholes 121 formed in equal spacing around their outer surfaces thereof; - a
rib unit 13 composed of a first, a second, and athird ribs ribs holes 121 of bothbearing blocks 121, while the via holes at the other end of theribs second rib 132; - a
canvas 14 wrapping theentire rib unit 13 and having afixed axle 141 engaged with thecanvas 14 at upper and lower ends thereof by high frequency bonding for achieving water tight effect and keeping flexibility of thecanvas 14, wherein thecanvas 14 is enclosed over thetransmission bar 11, furthermore,several holding rings 142 made of similar material as that of thecanvas 13 and bonded to thecanvas 14 by high frequency bonding are provided in order to tie the end position of each rib, besides, an air inlet/outlet 143 is respectively formed at each side of thecanvas 14 opposite to each other, wherein thefixed axle 141 is provided with a ball bearing; and - a
stationary base 15 conjoined with the canvas fixedaxle 141 and being sleeved over thetransmission bar 11 for firmly holding thecanvas 14, wherein at its side thereof is a cylindrically shapedpivoted block 151 turnable around apivoted axle 152 on thebase 15, theblock 151 has anengaging arm 1511 etended out from one side, thearm 1511 has ahook 1512 at its front end, and a pushingrod 1513 extended from the other side thereof, and arecess 1514 is formed inside of thepivoted block 151, and a lever is extended from thepivoted block 151. -
- The action of the
pivoted block 151 are described in Figs. 3A-3D. A tunnel like throughhole 153 is opened in the base at a properly offset position beneath thepivoted axle 152, at the end of the throughhole 153 near thepivot axle 152, aclogging portion 1531 is formed, while the other end is formed into a threadedportion 1532. Further, aball 154 is placed in theclogging portion 1531, and acoil spring 155 is set in the throughhole 153 with its one end forcibly pressing theball 154, while the other end thereof is engaged with the threadedportion 152 by screw combination. As shown in figs. 3A-3D, when thepivoted block 151 has not yet actuated by a external force, therecess 1514 is engaged with theball 154, when thepivoted block 151 is actuated by an external force, theball 154 is exerted a downward force so as to leave away from therecess 1514. In case thepivoted block 151 is displaced a certain angle, therecess 1514 now comes down to trap anotherball 156 so as to assist thepivoted block 151 to operate effectively. - A
bevel gear 16 encircles one end of thetransmission bar 11 at the stationary base (15) side, and agear wheel 17 is provided on it. - Two
stand 18 are engaged with a firstjoint plate 19 by screws, and the other end of eachstand 18 is bolted with thestationary base 15 by means of a protruded block. - A

The two end supports 191, 201 are for supporting thetransmission bar 11. - As soon as the
gear wheel 17 above thefloat 1 is driven to rotate clockwise, both bearingblocks 12 are moved relatively close to each other such that the threeribs canvas 14 is shrunk (see Fig. 2A). On the other hand, when thegear wheel 17 is driven to rotate counterclockwise, both bearingblocks 12 are moved away form each other such the threeribs canvas 14 expanded (see Fig. 2B). In this version, thefloat 1 floats up or sinks down in the water. - For understanding the structure of the transmission mechanism of the present invention, reference should be made to Fig. 4. The transmission mechanism includes:
- an
output shaft 2 having anair guide unit 21 sleeved onto a proper middle position of theoutput shaft 2, wherein the front end thereof is formed into anair outlet 211, while anair inlet 212 is formed at its side, a first and asecond sprockets output shaft 2 respectively, wherein theair guide unit 21 is provided with a ball bearing: - two

annular gear 8 to be coupled with thepinion gear 17 for driving the same so as to serve as an internal gear unit, wherein working of thepinion gear 17 causes the two bearingblocks 12 to move towards each other thereby making thefloat 1 shrink and loose buoyancy by discharging the inner air, and thefloat 1 sinks following the motion of the first and thesecond sprockets -
- Fig. 5 is a perspective view showing the internal structure of the present invention. The first
joint plate 19 is engaged with thestaple 61 of thefirst transmission chain 6 by screw combining its tapped hole with the tappedhole 611 of the staple 61, or by welding thereof such that the firstjoint plate 19 at one end of thefloat 1 is firmly engaged with thefirst transmission chain 6; similarly the secondjoint plate 20 is engaged with thestaple 71 of thesecond transmission chain 7 by screw combining its tapped hole with the tappedhole 711 of the staple 71, or by welding thereof such that the secondjoint plate 20 at the opposite end of thefloat 1 is firmly engaged with thesecond transmission chain 7. By doing so , thefloat 1 is settled between the twochains 6 an 7 so as to move together with them at a track defined by the twochains - Fig. 6 is the side view of Fig. 5, and further refer to Figs. 7A and 7B,
several floats 1 can be connected between the first and thesecond chains floats 1 be communicated with each other, a four-way tube 101 can be provided to an air inlet/outlet 143 installed at the outer side of one of thefloats 1, and a three-way tube 102 can be provide at the inner side thereof, and the three-way tubes 102 are provide to both inner/outer air inlet/outlet 143 for rest of thefloats 1. Furthermore, ahose 103 is used to interconnect each air inlet/outlet 143 of thefloats 1. Finally, external air is introduced into thefloats 1 viaair guide unit 21 by connecting the output end of thehose 103 with theair guide unit 21. Meanwhile, in order to prevent twisting of thehose 103 during operation of the present invention, thehose 103 laid under the first and thesecond chains clear spacing 5 reserved between the twotransmission shafts supporter 1021 is provided at one side of the three-way tube 102 (see Fig. 7B) installed on the air inlet/outlet 143 at outer side of thefloat 1 so as to trap thehose 103 thereat, and cause thefloat 1 along with its four-way tube 101 to locate thereby preventing the twisting of thehose 103 during movement of thefloat 1. - An embodiment of the present invention is illustrated in Fig. 7A.
- A L shaped
water tank 9 constructed according to Torricelli's law is provided, a firstelectromagnetic valve 91 is installed at the right upper side of the water thank 9, while a secondelectromagnetic valve 92 is installed at the left lower side thereof. Water is supplied into thewater tank 9 from the secondelectromagnetic valve 92. At this moment the firstelectromagnetic valve 91 is at closed state so that water can not overflow therefrom. The state of closing thevalve 91 and opening thevalve 92 is maintained until the water level reaches a height below theoutput shaft 2. Then thevalve 92 is closed, and thevalve 91 is opened. At this state, water does not flow out from thevalve 92 according to Torricelli's law, and the pressure inside thewater tank 9 is reduced so that the floats can move along smoothly. Meanwhile, theoutput shaft 2 andtransmission shafts water tank 9, and atransmission gear wheel 24 is coupled to theoutput shaft 2 at one end extended out of thewater tank 9 so as to output power. A ball bearing block 911 and anannular rubber collar 912 is applied to the tank wall at inner and outer side respectively from where theoutput shaft 2 goes out so as to prevent air leakage. The other end of theoutput shaft 2 and the fixed ends of bothtransmission shafts water tank 4, and theannular rubber collar 912 is made of a friction resist and heat withstanding material. - In another embodiment shown in Fig. 9, a
miniature water tank 93 is equipped abut on the outer wall of thewater tank 9 and is similarly pierced through by theoutput shaft 2. The wall of thewater tank 9 where theoutput shaft 2 pierced through is provided with theball bearing 911 and theannular rubber collar 912, whereas for theminiature tank 93, only anannular rubber collar 913 is provided. With this structure, the first and thesecond transmission chains tank 9 and theair guide unit 21 on theoutput shaft 2 is emerged above the water level so as to let the air in. Meanwhile, afirst actuating rod 94 is provided at the rear upper inner wall of thetank 9, and asecond actuating rod 95 is provided on the bottom of thetank 9 nearby thefirst chain 6. The twoactuating rods block 151 so as to cause thefloat 1 shrink or expand. When thefloat 1 is under the water level, the lever of the pivotedblock 151 is apart from the surface of thebevel gear 16, before thefloat 1 approaches thedriving gear wheel 41 of thetransmission shaft 4 thesecond actuating rod 95 will tap thelever 151 in advance such that thelever 151 swings to the left and is blocked on the surface of thebevel gear 16. On the other hand, thepinion 17 is in mesh with thedriving gear 42 and rotates. Meanwhile, by reason that the pivotedblock 151 has an inlaid tension spring provided at itsblocking terminal 1512 of the blocking rod 1511 (see Fig. 3C), the blocking terminal 1512 can not strongly trammel thebevel gear 16, but can only pressing it lightly. At this moment the two bearing blocks 12 of thefloat 1 is displaced gradually outward and extended so as to introduce external air into thefloat 1 via theair guide unit 21 thereby thefloat 1 is expanded. As soon as the buoyancy of thefloat 1 has overcome its own weight and floats up, the first and thesecond chains second transmission chains output shaft 2 together with thetransmission shaft float 1 approaches theannular gear 8, thefirst actuating rod 94 taps the lever of the pivotedblock 151 in advance so that the lever swings to the left and leaves away from the surface of thebevel gear 16 and thegear wheel 17 comes to, in mesh with theannular gear 8 and rotates. Then, the two bearing blocks 12 of thefloat 1 are gradually displaced inwards and thefloat 1 is shrunk to discharge the contained air into the other float which is gradually expanding. Thefloat 1 which entirely lost its air sinks down in the water by its own weight and by driving force of the first and thesecond chains second chains output shaft 2 thereby a continuous mechanical power output can be obtained. - Incidentally, the
water tank 10 may be constructed poly hedrical as shown in Fig. 10. - Returning to Figs. 8A and 8B which show the cross sectional view of the
air guide unit 21, anannular flange 213 is provided between theair outlet 211 andair inlet 212, and acheck damper 214 is rockingly hinged abut on theannular flange 213 with apivot axle 215. During the expanding and shrinking operation of the float, the required air may be absorbed from theair inlet 212 whereas thecheck damper 214 works to prohibit counter flow of air in the float. - It emerges from the above description that the hydraulic buoyanct force engine of the present invention has several noteworthy merits namely:
- 1. The mechanical power is obtained from the buoyant force only without need for help of other cources.
- 2.No sophisiticated structure is involved in the present invention which helps to reduce the production cost.
-
