Description

Technical Field

[0001] This invention relates to the field of water conservancy and hydropower engineering technology, and in particular to a hydropower generation device suitable for rivers with wide channels. Background Technology

[0002] The flow of rivers and oceans is an inexhaustible source of energy. If it can be used effectively, it can significantly improve the development and utilization of new energy sources and promote carbon neutrality.

[0003] Currently, the main method of hydropower generation in my country involves water flowing under gravity and impacting a generator, converting the water's potential energy into kinetic energy applied to the generator, which then converts that kinetic energy into electrical energy. However, this method is only suitable for rivers or water systems with large head differences, limiting its applicability and subject to significant terrain restrictions.

[0004] Currently, for rivers with small head differences but large channel widths, it is difficult to generate electricity by relying on topographic differences to create eddies. Because of the friction between the riverbanks and the sides of such wide rivers, the flow velocity in the middle is generally greater than that at the sides. If this characteristic could be utilized effectively, hydroelectric power generation could be achieved by exploiting the velocity differences at different points in the river. Currently, there are few hydroelectric power generation devices in China developed using this principle and suitable for rivers with large channel widths. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a hydroelectric power generation device suitable for rivers with wide channels.

[0029] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0030] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of the invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0031] like Figures 1-9 As shown, the present invention provides a hydroelectric power generation device suitable for rivers with wide channels, including an upper drive assembly, a lower drive assembly, and a generator 3. The generator 3 includes a housing, a flywheel, a flywheel connecting shaft 31, a flywheel connecting disc 32, and a fixing block 25. The flywheel connecting shaft 31 passes through the flywheel, and the flywheel connecting disc 32 is sleeved on the flywheel connecting shaft 31. One end of the fixing block 25 is fixedly connected to the housing, and the other end is fixed to the dam slope 1 on both sides of the river surface 17. The lower drive assembly is set in the river and is connected to the upper drive assembly. The upper drive assembly is connected to the flywheel connecting disc 32 in a transmission connection.

[0032] The present invention relates to a hydroelectric power generation device suitable for rivers with wide channels. It is equipped with a lower drive assembly and an upper drive assembly. The lower drive assembly is set in the river and drives the upper drive assembly to move by the power of the water flow. The spiral bar 4 in the upper drive assembly and the power drive component work together to convert the vertical force into the rotational force. In this way, the power drive component drives the flywheel in the generator 3 to rotate. During the rotation of the flywheel, it cuts the magnetic field lines, and the generator 3 can generate electricity.

[0033] Furthermore, in this embodiment, a cantilever connector 2 is also provided between the fixing block 25 and the dam slope protection 1. The cantilever connector 2 is made of steel beam or reinforced concrete beam. The fixing block 25 is made of steel or wood. The function of the cantilever connector 2 and the fixing block 25 is to fix the generator 3 on the upper side of the river surface 17.

[0034] Preferred, such as Figure 1 , Figure 7 , Figure 8As shown, the upper drive assembly includes a spiral strip 4, a top connecting block 6, a bottom connecting block 8, and a power drive component. The top connecting block 6 is sleeved on the outer periphery of the spiral strip 4 and can move up and down along the spiral strip 4. The bottom connecting block 8 is fixed to the bottom end of the spiral strip 4 and is used to connect with the lower drive assembly. The power drive component is fixedly connected to the top connecting block 6 and connected to the flywheel connecting disc 32. A spring damper 7 is also provided between the top connecting block 6 and the bottom connecting block 8. In this embodiment, a spiral through hole is provided inside the top connecting block 6. To ensure smoother movement of the top connecting block 6 up and down the spiral strip 4, the spiral through hole inside the top connecting block 6 is not exactly the same shape as the spiral strip 4. Furthermore, the spiral strip 4, the top connecting block 6, and the bottom connecting block 8 are all made of water-corrosion-resistant metal. The top connecting block 6 and the bottom connecting block 8 are both circular. Furthermore, the upper and lower ends of the spring damper 7 are connected to the top connecting block 6 and the bottom connecting block 8 via flanges and bearings, ensuring that the spring damper 7 only undergoes axial deformation. That is, when the top connecting block 6 moves downward on the spiral strip 4, the spring damper 7 is compressed; when the top connecting block 6 moves upward on the spiral strip 4, the spring damper 7 extends. In this embodiment, the spiral strip 4 is used to limit the rotational movement tendency of the multiple hollow blocks 5. The spring damper 7 is used so that when the hollow blocks 5 emerge from the river surface, the spring damper 7 can quickly push the top connecting block 6 to move away from the bottom connecting block 8, and can cause several hollow blocks 5 to rotate around the spiral strip 4.

[0035] Preferred, such as Figure 7 , Figure 9 As shown, the power drive component includes a first ring 61, a second ring 62, several hollow blocks 5, and several first connecting rods 63. The centers of the first ring 61 and the second ring 62 coincide with the center of the top connecting block 6. The top connecting block 6, the second ring 62, and the first ring 61 are arranged sequentially from the inside out. The first connecting rods 63 are disposed between the top connecting block 6 and the second ring 62, and the several hollow blocks 5 are disposed between the second ring 62 and the first ring 61. The several hollow blocks 5 are connected to the flywheel connecting plate 32 by telescopic rods 33. Further, in this embodiment, there are six first connecting rods 63, and the included angle between adjacent first connecting rods 63 is 60°. The first ring 61 and the second ring 62 are made of steel, and the diameter of the first ring 61 is larger than the diameter of the second ring 62. The telescopic rod 33 is a low-damping telescopic rod. When several hollow blocks 5 move up and down along the spiral 4, the telescopic rod 33 extends and retracts in time according to the distance between the several hollow blocks 5 and the flywheel connecting plate 32, and the rotation angle of the several hollow blocks 5 is the same as the rotation angle of the flywheel connecting plate 32.

[0036] Furthermore, such as Figure 7As shown, several hollow blocks 5 are evenly distributed between the inner circumference of the first ring 61 and the outer circumference of the second ring 62, connected by clamps or welding. The number of telescopic rods 33 is the same as the number of hollow blocks 5. The two ends of the telescopic rods 33 are respectively hinged to the hollow blocks 5 and the flywheel connecting plate 32 through hinge supports. The connection method of the hinge supports should ensure that the rotation angle of the hollow blocks 5 is the same as the rotation angle of the flywheel connecting plate 32. There are six hollow blocks 5, and the included angle between adjacent hollow blocks 5 is 60°. There are six telescopic rods 33, and the included angle between adjacent telescopic rods 33 is 60°.

[0037] Furthermore, such as Figures 7-9 As shown, in this embodiment, the hollow block 5 is shaped like a cone or an elliptical cone, wider at the top and narrower at the bottom. The purpose of designing the hollow block 5 as a cone or elliptical shape is to increase the buoyancy as it gradually submerges in the river water from top to bottom. The outer surface of the cone or elliptical cone is a spatial curved surface with a certain twist angle, which increases the contact area between the hollow block 5 and the river water when submerged. This allows several hollow blocks 5 on a single power drive component to rotate due to the difference in flow velocity across the river's width, thus enabling them to function like blades. The top surfaces of the several hollow blocks 5 are located on the same plane. In this embodiment, the hollow block 5 can be made of metal, wood, or alloy steel.

[0038] Furthermore, in this embodiment, in order to ensure that the hollow block 5 drives the flywheel connecting disc 32 through the telescopic rod 33 with minimal force loss, the axial direction of the spiral strip 4 coincides with the axial direction of the flywheel connecting shaft 31 in space, effectively avoiding the deviation when the telescopic rod 33 transmits force.

[0039] Preferred, such as Figures 2-6 As shown, the lower drive assembly includes a first crossbeam 10, a second connecting rod 9, a second crossbeam 12, and a water flow drive component. The second connecting rod 9 is fixedly connected to the bottom connecting block 8 in the upper drive assembly. The first crossbeam 10 is located above the second crossbeam 12, and the spatial extension direction of the first crossbeam 10 is perpendicular to the spatial extension direction of the second crossbeam 12. A slide rail 11 is provided on the top surface of the second crossbeam 12. The second connecting rod 9 passes through the first crossbeam 10 vertically, and the bottom end of the second connecting rod 9 is connected to the slide rail 11. A second crossbeam bearing is provided in the middle of the second crossbeam 12 along the vertical extension direction of the second crossbeam 12, and a support shaft 16 passes through the second crossbeam bearing. The second crossbeam 12 can rotate around the support shaft 16. The water flow drive component abuts against the bottom surface of the second crossbeam 12.

[0040] Furthermore, in this embodiment, a slider is provided inside the slide rail 11, and the bottom end of the second connecting rod 9 is connected to the slider through a ball joint.

[0041] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, in this embodiment, there are two first crossbeams 10, and the extension direction of the first crossbeams 10 is consistent with the direction of water flow. There is one second crossbeam 12, and the extension direction of the second crossbeam 12 is perpendicular to the direction of water flow (i.e., the width direction of the second crossbeam 12 coincides with the width direction of the river surface 17). There are two slide rails 11, and the two slide rails 11 are respectively set at both ends of the top surface of the second crossbeam 12. The two first crossbeams 10 have through holes in the vertical direction, and the second connecting rod 9 passes through the through holes. The top end of the second connecting rod 9 is fixedly connected to the bottom connecting block 8, and the bottom end of the second connecting rod 9 is connected to the slide rail 11. When the second crossbeam 12 rotates around the support shaft 16, the movement of the second connecting rod 9 is the resultant movement of up and down in the through hole of the first crossbeam 10 and the sliding motion of the slider in the slide rail 11. The up-and-down movement of the second connecting rod 9 drives the up-and-down movement of the spiral 4, causing several hollow blocks 5 on the power drive component to sink into or float out of the river surface 17; under the impact of the water flow on several hollow blocks 5 or under the elastic force of the spring damper 7, the top connecting block 6 rotates around the spiral 4, thereby driving the rotation of the hollow blocks 5, and realizing the power generation of the generator 3.

[0042] The first crossbeam 10 is a composite structural beam, which ensures good load-bearing performance even when through holes are opened. The second crossbeam 12 is a steel beam or a composite structural beam.

[0043] Preferred, such as Figure 2 , Figure 3 As shown, the first crossbeam 10 has first crossbeam fixing columns 13 at both ends, and the support shaft 16 has support shaft fixing columns 14 at both ends. The support shaft 16 is non-rotatably mounted on the support shaft fixing columns 14.

[0044] Preferred, such as Figures 1-6As shown, the water flow drive includes a first rotating shaft 18, a cam 19, a first gear 21, a second gear 22, a second rotating shaft 23, and an impeller 24. The first rotating shaft 18 is disposed on both sides of the support shaft 16. The cam 19 is sleeved on the first rotating shaft 18 and abuts against the bottom surface of the second crossbeam 12. The first gear 21 is sleeved on the end of the first rotating shaft 18. First rotating shaft fixing posts 15 are provided at both axial ends of the first rotating shaft 18. Second rotating shaft fixing posts 20 are provided at both axial ends of the second rotating shaft 23. The second rotating shaft 23 is rotatably disposed on the second rotating shaft fixing posts 20. The second gear 22 is sleeved on the outer periphery of the second rotating shaft 23, and the first gear 21 meshes with the second gear 22. The impeller 24 is disposed at the end of the second rotating shaft 23. Further, in this embodiment, there are two first rotating shafts 18, and the first rotating shafts 18 and the support shaft 16 are in a parallel state in space. Two first rotating shafts 18 are symmetrically arranged about the axis of the support shaft 16. There are two cams 19. The two cams 19 are arranged on both sides of the support shaft 16. When the outermost edge of the two cams 19 is at the top, the other is at the bottom. That is, the two cams 19 take turns lifting the two ends of the second crossbeam 12, so that the second crossbeam 12 forms a movement trend similar to a "seesaw".

[0045] Furthermore, one end of the first rotating shaft 18 extends out of the first rotating shaft fixing post 15, and the first gear 21 is disposed on this end. The second gear 22 is disposed on the second rotating shaft 23 near the support shaft fixing post 14, and meshes with the two first gears 21.

[0046] Preferably, the outer surface of the cam 19 is provided with a smooth contact layer, and the bottom surface of the second crossbeam 12 at the point where it abuts against the cam 19 is provided with a sliding layer, with the smooth contact layer abutting against the sliding layer. The smooth contact layer is made of one of polytetrafluoroethylene (PTFE), modified PTFE, ultra-high molecular weight polyethylene (UHMWPE), and ultra-high performance PTFE. The sliding layer is also made of one of PTFE, modified PTFE, UHMWPE, and ultra-high performance PTFE. The purpose of providing a smooth contact layer on the outer surface of the cam 19 and a sliding layer on the bottom surface of the second crossbeam 12 is to reduce wear between the cam 19 and the second crossbeam 12.

[0047] Preferred, such as Figure 2 As shown, there are two first rotating shafts 18, two first gears 21, and one second gear 22. The first gears 21 and the second gear 22 are meshed together to form an idler wheel. The impeller 24 is arranged facing the direction of the water flow, making full use of the water flow to drive the impeller 24.

[0048] Furthermore, the bottoms of the first crossbeam fixing column 13, the support shaft fixing column 14, the first rotating shaft fixing column 15, and the second rotating shaft fixing column 20 are all made of reinforced concrete columns or composite structural columns, and are fixedly connected to the concrete stilling basin bottom slab or the concrete riverbed bottom slab. Furthermore, the tops of the first rotating shaft fixing column 15 and the second rotating shaft fixing column 20 are provided with flanges and bearings, respectively, for the rotational movement of the first rotating shaft 18 and the second rotating shaft 23.

[0049] Furthermore, in this embodiment, the second crossbeam 12 is driven by two cams 19 so that when one end is at its highest position, the corresponding multiple hollow blocks 5 on the upper side of that end can be exposed above the river surface 17, in order to eliminate the impact of the water flow on the corresponding multiple hollow blocks 5.

[0050] Furthermore, in this embodiment, there are two of each of the second connecting rod 9, the spiral bar 4, and the generator 3.

[0051] The working principle of the hydroelectric power generation device applicable to rivers with wide channels, as disclosed in this invention, is as follows:

[0052] First, fix the first crossbeam fixing column 13, the support shaft fixing column 14, the first rotating shaft fixing column 15, and the second rotating shaft fixing column 20 to the bottom plate of the concrete stilling basin or the bottom plate of the concrete river channel. At this time, the lower drive assembly is fixedly installed in the riverbed.

[0053] Next, the generator 3 is installed on the dam slope protection 1 through the fixing block 25 and the cantilever connector 2, and the second connecting rod 9 of the lower drive assembly is fixedly connected to the bottom connecting block 8 of the upper drive assembly; so that the axis of the spiral 4 coincides with the axis of the flywheel connecting shaft 31 of the generator 3 in the vertical direction.

[0054] When the river water flows, the impeller 24 on the second rotating shaft 23 rotates due to the impact of the water flow, driving the second gear 22 on the second rotating shaft 23 to rotate. The second gear 22 drives the two first gears 21 to rotate, and the idler wheel begins to work. The two first gears 21 drive the two first rotating shafts 18 to rotate respectively. The cams 19 on the first rotating shafts 18 cause the second crossbeam 12 to rotate around the support shaft 16 through collision. The second crossbeam 12 performs a seesaw-like motion.

[0055] When one end of the second crossbeam 12 descends, the second connecting rod 9 at that end will descend vertically while its bottom slides within the slide rail 11. The descent of the second connecting rod 9 will cause the spiral strip 4 at that end to descend. The descent of the spiral strip 4 will drive the top connecting block 6 and multiple hollow blocks 5 to descend. The multiple hollow blocks 5 will gradually be submerged in the water. At this time, because the flow velocity in the middle of the river is greater than that on both sides, the hollow block 5 near the support shaft 16 experiences a greater impact than the hollow block 5 far from the support shaft 16, thus causing the top connecting block 6 to rotate around the spiral strip 4 (as shown). Figure 5 As shown in the diagram, the top connecting block 6 descends along the spiral 4, and the spring damper 7 is continuously compressed and stores energy. During this process, because multiple hollow blocks 5 drive the top connecting block 6 to rotate around the spiral 4, the hollow blocks 5 will also drive the flywheel connecting disc 32 to rotate through the telescopic rod 33, thereby driving the flywheel connecting shaft 31 and the flywheel to rotate. The flywheel cuts the magnetic field lines, and the generator 3 starts to generate electricity.

[0056] When one end of the second crossbeam 12 rises, the second connecting rod 9 at that end will rise vertically, and the bottom of the second connecting rod 9 will slide within the slide rail 11. The rise of the second connecting rod 9 will drive the rise of the spiral strip 4 at that end. The rise of the spiral strip 4 will drive the rise of the top connecting block 6 and multiple hollow blocks 5. Because the hollow blocks 5 are shaped with a wider top and a narrower bottom, they have a tendency to move upward quickly when they rise. At the same time, as the hollow blocks 5 gradually leave the river surface 17, the impact force of the river water on the hollow blocks 5 is greatly weakened (i.e., the downward rotation tendency of the top connecting block 6 is weakened). At this time, the spring damper 7 will extend under the action of elasticity to release the energy generated by compression. The direction of the extension of the spring damper 7 is the same as the direction of the buoyancy force on the hollow blocks 5. Therefore, the upward displacement tendency of the top connecting block 6 is gradually greater than the downward rotation tendency of the top connecting block 6. The top connecting block 6 will drive the hollow blocks 5 to rotate, and the direction of rotation is opposite to the direction of rotation when the top connecting block 6 descends. The rotation of the hollow block 5 causes the telescopic rod 33 to rotate, which in turn causes the flywheel connecting plate 32 to rotate. The flywheel connecting shaft 31 and the flywheel rotate, and the flywheel cuts the magnetic field lines, causing the generator 3 to start generating electricity.

[0057] Because there are two second connecting rods 9 at both ends of the second crossbeam 12, when one end of the second crossbeam 12 descends, the other end will rise, so the two generators 3 will continuously generate electricity.

[0058] The present invention relates to a hydroelectric power generation device suitable for rivers with wide channels. It is equipped with two cams 19, which drive a second crossbeam 12 to rotate around a support shaft 16, creating a seesaw-like motion. During this seesaw motion, the position of the spiral strip 4 continuously rises and falls. When the spiral strip 4 descends, multiple hollow blocks 5 submerge in the water, generating a rotational tendency that drives the flywheel of the generator 3 to generate electricity. Conversely, when the spiral strip 4 rises, the hollow blocks 5 emerge from the water. Losing the water flow's driving force, these hollow blocks 5 rotate in the opposite direction to their descent, once again driving the generator 3 to operate.

[0059] This invention utilizes the characteristic of different flow velocities at different locations in a wide river channel to drive multiple hollow blocks 5 to rotate around a spiral strip 4. Regardless of whether the spiral strip 4 is descending or ascending, it can drive the generator 3 to work. This solves the problem that existing hydropower generation mostly relies on the conversion of gravitational potential energy into kinetic energy, and then kinetic energy into electrical energy. It also solves the problem of existing hydropower generation relying on the drop of water flow, thus expanding the applicable scope of hydropower generation devices.

[0060] Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0061] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
