Description
- The present invention relates to a power apparatus, particularly to a multi-vane-type flow kinetic energy device.
- Since the industrial revolution, the world has been going gradually into an era with the manual power being replaced by mechanical power, and as for the energy sources, the chemical energy source becomes dominant instead of the physical energy source. By using coal, petroleum and other organic matter as fuel, energy is produced through combustion. And during the combustion of the fuel, harmful material is released and mixed into the air, resulting in pollution to the environment. Additionally, in order to obtain more fuel to produce more energy, human beings are going to exploit it further excessively, and this worsens the pollution to the environment and leads to the greenhouse effect, and then imperils the future of mankind. Therefore, men of insight propose to use renewable energy sources, such as wind power, water power, and tidal energy and so on, so as to reduce the application of chemical energy sources.
- The technical problem to be solved by the present invention is to provide a multi-vane-type flow kinetic energy device that is of simple structure, low cost and can output power continuously by taking advantage of the fluid power.
- In order to solve the technical problem mentioned above, the present invention adopts the following technical solution:
-
- a multi-vane-type flow kinetic energy device, placed in the atmosphere with an air current or in a body of water with a water current, comprising:
- a wheel shaft;
- multiple wheel vanes, fixed on the wheel shaft along an axial direction of the wheel shaft, the multiple wheel vanes being uniformly distributed on the wheel shaft and in a radiating arrangement, and the wheel vanes driving the wheel shaft to rotate unidirectionally under the effect of fluid power of the water current or the air current; wherein
- the wheel vanes comprise a wheel vane frame and multiple windows formed in the wheel vane frame, and the window vanes are provided on the windows to cover the windows in a forward flow region and to automatically open the windows in a counter-flow region, and all of the window vanes are placed on the same side of the wheel vanes.
- Preferably, the window is formed by crossing transverse rod-shape bodies and longitudinal rod-shape bodies perpendicular to each other, wherein the transverse rod-shape body is parallel to the wheel shaft, and spaces of two adjacent transverse rod-shape bodies are equal, while spaces of two adjacent longitudinal rod-shape bodies are equal.
- Preferably, when the wheel shaft is disposed horizontally in use, the window vane is rotatably connected on the outer edge of the window parallel to the wheel shaft, and when the wheel shaft is disposed vertically in use, the window vane is rotatably connected on the outer edge of the window parallel to the wheel shaft or the window vane is rotatably connected on the upper edge of the window perpendicular to wheel shaft.
- Preferably, the window vane is hinge-joined to the outer edge or the upper edge of the window by a hinge.
- Preferably, a mortise is provided on the outer edge or the upper edge of the window, while a tenon, which is protruding and used for inserting into the mortise so that the window vane is rotatably connected on the window, is provided on the window vane.
- Preferably, a shaft lever is provided on the outer edge or the upper edge of the window, and a window vane hole into which the shaft lever penetrates is provided on the window vane, so that the window vane is rotatably connected on the window.
- Preferably, the area of the window vane is larger than the area of the corresponding window, resulting in that it is sufficient for the window vane to fully cover the corresponding window, and the adjacent window vanes do not overlap each other.
- Preferably, the area of the window vane is smaller than or equal to the area of the corresponding window, and a stopping bar is provided on the edge of the window, which is used to make the window vanes always stay at the same side of the window without rotating to the other side of the window.
- Preferably, one face of the window vane recesses inwardly while the other face protrudes outwardly, and the face recessing inwardly adheres to the wheel vane frame, while the face protruding outwardly faces away from the wheel vane frame.
- Compared with the prior art, the beneficial advantages of the multi-vane-type flow kinetic energy device of the present invention lie in:
- 1. The multi-vane-type flow kinetic energy device of the present invention, by taking advantage of the window vane on the wheel vane in the forward flow region automatically covering so as to close the window of the wheel vane and the window vane on the wheel vane in the counter-flow region automatically opening so as to open the window of the wheel vane, retains the windows on half of the wheel vanes in an opened state when the half of the wheel vanes rotate facing the fluid flowing direction, thereby significantly lowering the resistance to the fluid flow, and at the same time, retains the windows on half of the wheel vanes in a closed state, rotating continuously due to the driving of the fluid power, and further driving the wheel shaft to rotate, and thus, the rotating wheel shaft can output power continuously.
- 2. When the multi-vane-type flow kinetic energy device of the present invention is placed in the atmosphere at a location with air flowing, the effect to generate electricity by wind power is more prominent, since the windage area of the wheel vane can be enlarged as compared to the conventional wind turbine.
- 3. The multi-vane-type flow kinetic energy device of the present invention can entirely hide in the water when it is in use, thus this only leads to slight harm done to the natural environment and the ecological environment and also leads to little influence on the boat navigation channel. At the same time, when the multi-vane-type flow kinetic energy device is placed in rivers and seas, there is relatively small limitation by the environment, and it is possible to construct relatively large volume so as to obtain relatively large output power.
- 4. Because the multi-vane-type flow kinetic energy device of the present invention uses wind power or water flow power, which are both physical energy sources, it has the advantages of permanent existence, significant power, inexhaustible, and no pollution to the environment.
- 5. The multi-vane-type flow kinetic energy device of the present invention is of simple structure, easy to manufacture and low cost, and can be popularized and applied all over the world.

- Firstly, it is necessary to note that, the turning surface mentioned hereinafter refers to the plane parallel to the fluid flowing direction and passing through the wheel shaft axial line when the wheel shaft is disposed horizontally in the atmosphere or water. The turning surface divides the space into two regions: a forward flow region in which the wheel vane rotates along the fluid flowing direction; a counter-flow region in which the wheel vane rotates against the fluid flowing direction. A median plane refers to the plane perpendicular to the fluid flowing direction and passing through the wheel shaft axial line.
- The multi-vane-type flow kinetic energy device provided in the present invention is placed in the atmosphere with an air current or a body of water with a water current, and the window vane on the wheel vane in the forward flow region covers the corresponding window naturally due to the effect of the fluid propulsion while the window vane on the wheel vane in the counter-flow region opens the corresponding window naturally due to the effect of the fluid propulsion, so that the wheel vane drives the wheel shaft to rotate under the fluid flowing effect, in order to output power continuously.
- Specifically, as shown in
FIG. 1 andFIG. 2 , a multi-vane-type flow kinetic energy device disclosed in the present invention includes awheel shaft 2 andmultiple wheel vanes 1, whereas thewheel vanes 1 are fixed on thewheel shaft 2 along the axial direction of thewheel shaft 2, and themultiple wheel vanes 1 are uniformly distributed on thewheel shaft 2 and in a radiating arrangement. The rotation of thewheel vanes 1 will drive thewheel shaft 2 to rotate unidirectionally under the fluid power effect of the water current or the air current. - The
wheel vane 1 is constituted of awheel vane frame 7 as shown inFIG. 2 , and multiple hollow andunblocked windows 4 are formed in thewheel vane frame 7. In the present embodiment, thewindows 4 are formed by the spacing of transversely and longitudinally crossing rod-shape bodies. Awindow vane 3 is provided on eachwindow 4 to cover thewindow 4 in theforward flow region 11 and to automatically open thewindow 4 in thecounter-flow region 12, and all of thewindow vanes 3 are placed on the same side of thewheel vane 1. As shown inFIG. 2 , thewheel vane frame 7 disclosed in the present embodiment is rectangular, and each of thewindows 4 is also rectangular, while rectangular windows are the most economical to manufacture and the manufacturing efficiency is the highest. Besides, the longer side of the rectangular window is made to be parallel to the wheel shaftaxial line 6, and in this way, it is easier for thewindow vane 3 hinge-joined to the windowouter edge 5 to open. Practically, thewheel vane frame 7 and thewindow 4 in the present invention are not limited to these forms, for example, the structure of thewheel vane frame 7 is a curvilinear shape or a fan shape, and the shape of thewindow 4 can also be an arc shape or other shapes, as long as thewheel vanes 1 can drive thewheel shaft 2 to rotate continuously and unidirectionally under the propulsion of the fluid. At this time, thewindow vane 3 should vary according to the variation of the shape of thewindow 4, but the directions in which thewindow vane 3 opens and covers are unchanged. - Additionally, in the present embodiment shown in
FIG. 2 , it is only an illustrative example that fourwindows 4 are provided on each of thewheel vanes 1 along the radial direction of thewheel shaft 2, but practically, the number of theradial window vanes 3 can be determined according to the practical requirement without any limitation. Moreover, the number of thewindows 4 provided on each of thewheel vanes 1 along the direction of the wheel shaftaxial line 6 is not limited to eight, but can be determined according to the practical requirement. For the sake of clarity, only thewindow 4 is shown inFIG. 2 but thewindow vane 3 is not, and inFIG. 2 , one of the window spaces is indicated by dark color. - In order to realize that the
window vane 3 is rotatably connected on thewindow 4, so that thewindow vane 3 covers thewindow 4 in theforward flow region 11 and opens thewindow 4 in thecounter-flow region 12 under the propulsion of the fluid, thewindow vane 3 can be rotatably connected in various ways. As shown inFIG. 3 toFIG. 5 , amortise 9 is provided on the edge (that is, the edge parallel to thewheel shaft 2 in this embodiment, and hereinafter, simply referred as a window outer edge 5) of thewindow 4 far away from thewheel shaft 2. Atenon 8, which is protruding and used for being inserted into themortise 9 so that thewindow vane 3 is rotatably connected on thewindow 4, is provided on thewindow vane 3. As shown inFIG. 6 toFIG. 8 , thewindow vane 3 can also be hinge-joined to the windowouter edge 5 by ahinge 10. The rotatable connection of the window vane can also be realized in the way as shown inFIG. 9 toFIG. 11 . Ashaft lever 16 is provided on the windowouter edge 5, and awindow vane hole 17 into which theshaft lever 16 penetrates is provided on thewindow vane 3, so that thewindow vane 3 is rotatably connected on the windowouter edge 5. If the windowouter edge 5 itself is a round-rod shape, then, the additional shaft lever can be removed, and the windowouter edge 5 can be made to pass through thewindow vane hole 17 directly, so that thewindow vane 3 is rotatably connected on the windowouter edge 5. - With continued reference to
FIGS. 3-8 , in order to make thewindow vane 3 cover thewindow 4 so that the fluid propulsion force subjected by the wheel vane increases in theforward flow region 11, in the present embodiment, the area of thewindow vane 3 is slightly larger than the area of thecorresponding window 4, resulting in that it is sufficient for thewindow vane 3 to fully cover thecorresponding window 4, and theadjacent window vanes 3 should not overlap each other in order to ensure that their actions do not affect each other. - Certainly, it is also possible if the area of the
window vane 3 is not larger than the area of thewindow 4, and as shown inFIG. 9 toFIG. 11 , the area of thewindow vane 3 is slightly smaller than or equal to the area of thecorresponding window 4. A stoppingbar 15 is provided on an edge of thewindow 4, which is used to make thewindow vane 3 always stay at the same side of thewindow 4 without rotating to the other side of thewindow 4. The function of the stoppingbar 15 is mainly to press thewheel vane frame 7 when thewindow vane 3 is subjected to the action force of the fluid in theforward flow region 11, due to the existence of the stoppingbar 15, the action force of the fluid subjected by thewindow vane 3 is transmitted to thewheel vane frame 7 through the stoppingbar 15, so as to drive thewheel shaft 2 to rotate. The stoppingbar 15 can be provided in various ways and is not limited to the case of short and small bar shape shown inFIG. 9 , for example, the stoppingbar 15 can be provided as a long bar shape passing through thewhole window 4, and the bar shape can be either horizontal or vertical, but of course, it can be slanted. Moreover, a plurality of stoppingbars 15 can be provided. Additionally, the stoppingbar 15 can also be a multiple grid shape structure formed in thewindow 4. - As shown in
FIGS. 4, 5, 7, 8, 10 and 11 , thewindow vane 3 in the present embodiment is non-planar but with certain radian, that is, one side face of thewindow vane 3 recesses inwardly toward the other side face, and correspondingly, the other side face protrudes outwardly, whereas the face recessing inwardly adheres to thewheel vane frame 7, and the face protruding outwardly faces away from thewheel vane frame 7. The aim of thus provision is to make thewindow vane 3 in theforward flow region 11 adhere to thewindow 4 better, and accordingly increase the propulsion force acted on thewindow vane 3 by the fluid. Certainly, it is also possible if thewindow vane 3 is provided to be flat without a radian, and thewindow vane 3 will also open thewindow 4 in thecounter-flow region 12 and close thewindow 4 in theforward flow region 11 under the propulsion effect of the fluid. - Additionally, with continued reference to
FIG. 2 , thewindow 4 in the present embodiment is formed by crossing transverse rod-shape bodies and longitudinal rod-shape bodies perpendicular to each other, wherein spaces of two adjacent transverse rod-shape bodies are equal, and spaces of two adjacent longitudinal rod-shape bodies are equal, so that the sizes and shapes of the formedwindows 4 are completely the same, but practically, the sizes and shapes of thewindows 4 can be different. Moreover, it is shown in the present embodiment that eachwindow 4 is rotatably connected with onewindow vane 3 respectively, but practically, two ormore windows 4 can use onecommon window vane 3. Or it is also possible that onewindow 4 can be provided with two ormore window vanes 3. However, it has to be ensured that thewindow vane 3 always stays on the same side of thewindow 4 without rotating to the other side of thewindow 4 during rotation. Whenmultiple windows 4 use onecommon window vane 3, the frame between the adjacent twowindows 4 functions as a stoppingbar 15. - When in use, the multi-vane-type flow kinetic energy device of the present invention can be disposed horizontally according to the axial direction of the wheel shaft (as shown in
FIG. 1 toFIG. 2 ), or can be disposed vertically according to the axial direction of the wheel shaft (not shown in the figures).The structure of the multi-vane-type flow kinetic energy device is the same no matter it is disposed horizontally or disposed vertically, moreover, the working principles are also the same, and thewindow vane 3 is hinge-joined to the windowouter edge 5. When the multi-vane-type flow kinetic energy device of the present invention is placed in the fluid, such as the atmosphere with an air current or a body of water with a water current, the fluid flowing direction crosses with the wheel shaft axial line so as to form a turningsurface 13, wherein the turningsurface 13 divides the space into theforward flow region 11 and thecounter-flow region 12. Thewindow vane 3 on thewheel vane 1 covers thewindow 4 due to the effect of the fluid propulsion in theforward flow region 11, and thewindow vane 3 on thewheel vane 1 opens thewindow 4 due to the effect of the fluid propulsion in thecounter-flow region 12, so that the resistance is reduced when thewheel vane 1 in thecounter-flow region 12 rotates reversely, and at the same time, thewheel vane 1 in theforward flow region 11 drives the wheel shaft to rotate under the fluid flowing effect, in order to output power continuously. - Additionally, when the
wheel shaft 2 is disposed vertically, the multi-vane-type flow kinetic energy device of the present invention can also adopt the structure shown inFIG. 12 andFIG. 13 in addition to adopting the same structure as the one adopted when thewheel shaft 2 is horizontally disposed. As shown inFIG. 1 andFIG. 12 , the difference only lies in that thewindow vanes 3 are hinge-joined to thewindow 4 at different positions, while other structures are completely the same. With continued reference toFIG. 12 , thewindow vane 3 is rotatably connected on one side edge of thewindow 4 perpendicular to the axial direction of the wheel shaft, that is, as shown inFIG. 13 , when thewheel shaft 2 is vertically disposed, thewindow vane 3 is hinge-joined to the windowupper edge 18 of thewindow 4. - The working principle and the working process of the multi-vane-type flow kinetic energy device of the present invention is briefly explained as follows with reference to the accompany drawings by taking the wheel shaft disposed horizontally as an example:
- When in use, the multi-vane-type flow kinetic energy device of the present invention is placed in the fluid, that is, disposed in the way as shown in
FIG. 1 . - In the following, it will be explained by taking four
wheel vanes 1 as an example. As shown inFIG. 14 andFIG. 15 , now these four wheel vanes are respectively defined as a wheel vane 1 a, awheel vane 1 b, awheel vane 1 c and awheel vane 1 d, and the arrow directions inFIG. 14 andFIG. 15 indicate the flow directions of the fluid. - As shown in
FIG. 14 , when the wheel vane la in theforward flow region 11 rotates to approach the turningsurface 13, the protruding face of thewindow vane 3 slightly protruding outwardly still closes thewindow 4 under the propulsion effect of the fluid (it is the same if thewindow vane 3 doesn't protrude outwardly), and the wheel vane la continues to rotate and then crosses over the turningsurface 13 to enter into thecounter-flow region 12. And then as shown inFIG. 15 , the recessing face of thewindow vane 3 of the wheel vane lb faces the flowing fluid, and naturally opens thewindow 4 under the propulsion effect of the fluid. - Basically, when the wheel vane la enters into the
forward flow region 11 but hasn't crossed over themedian plane 14, the subjected action force by the fluid propulsion is the most distinct. After the wheel vane la crosses over themedian plane 14, the subjected action force by the fluid propulsion will decrease, and at this time, the fluid still flows along the previous flowing direction, and no other force acts on thewindow vane 3 except the gravitational force. If placed in water, thewindow vane 3 will be made of the material whose specific weight or effective specific weight is equivalent to that of water, so that the gravitational force subjected by the wheel vane la cancels the buoyancy of water. Therefore, after the wheel vane la crosses over themedian plane 14, thewindow vane 3 still adheres to thewindow 4, after all, in practice, the fluid flowing direction may vary slightly. However, because thewindow vane 3 is hinge-joined to the windowouter edge 5 so as to move freely, even though the wheel vane la hasn't crossed over the turningsurface 13 to enter into thecounter-flow region 12, thewindow vane 3 may slightly open due to the fluid action force varying according to the practical condition but won't contribute to the resistance to the rotation of the wheel vane la. If placed in the atmosphere, thewindow vane 3 will be made of lighter material. It won't contribute to the resistance to the rotation of the wheel vane la even if thewindow vanes 3 may open slightly before crossing over the turningsurface 13 and entering into thecounter-flow region 12. - As shown in
FIG. 14 again, when thewheel vane 1 c in thecounter-flow region 12 rotates to approach the turningsurface 13, the protruding face of thewindow vane 3 which slightly protrudes outwardly is about to close thewindow 4 under the propulsion effect of the fluid (it is the same if thewindow vane 3 doesn't protrude outwardly), thewheel vane 1 c continues to rotate and then crosses over the turningsurface 13 to enter into theforward flow region 11. And as shown inFIG. 15 , the protruding face of thewindow vane 3 of the wheel vane ld faces the flowing fluid, and closes thewindow 4 under the propulsion effect of the fluid. - Because of the fluid power effect, the fluid continuously passes through the multi-vane-type flow kinetic energy device of the present invention, so as to continuously drive the
wheel vane 1 and then drive thewheel shaft 2 to rotate, endlessly, in order to generate kinetic energy, and the kinetic energy generated by thewheel shaft 2 can be output to generate electricity. - Energy losses of the multi-vane-type flow kinetic energy device of the present invention mainly include the following four parts: 1) the mechanical friction of the
wheel shaft 2; 2) energy consumed to open thewindow vane 3 when thewheel vane 1 enters into thecounter-flow region 12; 3) energy consumed to block the fluid by the actual area of thewheel vane frame 7 when thewheel vane 1 rotates in thecounter-flow region 12; 4) energy consumed when the multi-vane-type flow kinetic energy device of the present invention rotates with its entire mass. - All of the four parts of energy losses are almost fixed, and normally, under the huge energy action force of the air current with strong wind or of the water current in the river or the sea, the energy generated by the fluid passing through the multi-vane-type flow kinetic energy device of the present invention and driving the
wheel vane 1 to rotate is enormous far beyond the energy losses. After canceling the energy losses, there still remains a large amount of energy to drive the generator unit to generate electricity. - In the following, the energy generated by the multi-vane-type flow kinetic energy device of the present invention will be explained by preliminary estimation through mathematical calculation: assuming that the radial length of the
wheel vane 1 is R, and assuming that the axial length of thewheel vane 1 is L, so the area of thewheel vane 1 is RL. Assuming that the time required by the fluid flowing over a distance of r along the direction of the turningsurface 13 is t, then the fluid velocity v=r/t. Fluid density is A. - The preliminarily estimated Power P=(½) mv2/t=(½)ρrRLv2/t=(½) ρ RLv3.
- If placed in water current, water density ρ=1000 Kg/m3.
- Assuming that R is 1 m, the length of the wheel vane L=1000 m, and water flow velocity v is 1 meter/second, then the Power P=(½)*1000*1*1000*13=0.5 MW. As for the same apparatus, if placed in water current with the water flow velocity v being 3 meter/second, then the Power P=(½)*1000*1*1000*33=13.5 MW.
- If placed in strong wind, air density ρ=0.225 Kg/m3.
- Assuming that R is 1 meter, and the length of the wheel vane L=100 meters, so when the wind velocity v is 10 meter/second, Power P=(½)*0.225*1*100*103=11.2 KW. As for the same apparatus, if placed in the strong wind with wind velocity v being 20 meter/second, Power P=(½)*0.225*1*100*203=90 KW.
- Comparison of the generating capacities:
- The Three Gorges Dam hydropower station is equipped with thirty-two 700-thousand-kilowatt water turbine generator units, and additionally, there are two 50-thousand-kilowatt power supply sets, so the total installed capacity is 22.5 million kilowatts, that is, 22500 million watts. The middle reaches of the Yangtze River is one thousand kilometers long, and the average flowing velocity is 1 meter/second. So tens of thousands of multi-vane-type flow kinetic energy device, with the radial length of the wheel vane being 1 meter and the axial length being 1000 meters, can be employed in the river. In this way, the electricity generating capacity can exceed the electricity generating capacity of the Three Gorges Dam hydropower station. The water flowing velocity of the upper reaches of the Yangtze River is up to 3 meter/second, and for the same apparatus, the electricity generating capacity can even be increased by tens of times. In fact, the total annual average amount of water resources in the Yangtze River Basin is 996 billion cubic meters, and the theoretical hydropower reserves of the whole Basin is about 0.28 billion kilowatts, so the amount that can be developed is about 0.26 billion kilowatts, which is about 11 times of the electricity generating capacity of the Three Gorges Dam hydropower station, and if half of the energy is to convert into electricity, there will be 5 times of the electricity generating capacity of the Three Gorges Dam hydropower station.
- Additionally, the potential energy stored in the ocean current is much huger. The theoretical average power of the current in China's coastal seas is 0.14 billion kilowatts. The Gulf Stream System in the Atlantic Ocean along the coast of The United States reaches 74˜93 million cubic meters/sec, exceeding the total of all rivers on the land by 80 times. If compared with the rivers in China, it is about 2600 times of the flow amount of the Yangtze River, or 57000 times of that of the Yellow River. Researchers from the Woods Hole Oceanographic Institution pointed out that, the energy brought by the Gulf Stream System, due to wind, the Earth's rotation and the heat heading toward the Arctic, is equivalent to 2000 times the electricity generating capacity of The United States of America.
- Kinetic energy resources in rivers and seas in the world are rich. If it is considered that the multi-vane-type flow kinetic energy device of the present invention is appropriately employed in the rivers and seas in the whole world, then it is sufficient for the electricity generating capacity to replace all existing thermal power generation and nuclear power generation facilities. It will greatly reduce harm done to mankind because of no more waste gas discharged by thermal power generation. At the same time, it will greatly reduce the danger of nuclear radiation leak.
- The embodiments above are only exemplary embodiments of the present invention but are not used to limit the present invention. The protection scope of the invention is defined by the claims. A person skilled in the art can make various modifications or equivalent substitutes to the present invention within the spirit and protection scope of the present invention, and such modifications or equivalent substitutes should be construed to fall into the protection scope of the present invention.
