Description

Technical Field

[0001] The invention relates to the technical field of water cycle power generation, in particular to a solid water cycle energy-saving power generation system. Background Art

[0002] Currently, renewable energy generation technologies primarily include wind power, solar photovoltaics, and traditional pumped storage, but each of these technologies has significant drawbacks. Wind power generation relies on specific geographical conditions and must be constructed in areas with high wind frequency, such as high mountains and coastal areas. This not only results in high infrastructure costs but also causes certain damage to the natural environment. Furthermore, wind power generation is limited by wind speed, resulting in only approximately 2,500 hours of effective power generation per year, energy conversion efficiency less than 30%, and a payback period of 5-8 years. Solar photovoltaic power generation is similarly limited by weather conditions, with only approximately 1,270 hours of effective power generation per year. Furthermore, photovoltaic panels require a large footprint, high maintenance costs, and low energy conversion efficiency, resulting in a payback period of approximately 5-6 years. While traditional pumped storage can regulate power grid peaks and valleys, it relies on large reservoirs, occupies a large area, has strict topographical requirements, and suffers from evaporation losses.

[0003] Common drawbacks of existing clean energy technologies include: dependence on natural conditions (such as wind and sunlight), intermittent power generation; low energy conversion efficiency; high construction costs and long payback periods; strict site requirements and limited flexibility; and the potential ecological impact of large-scale facilities. Therefore, there is an urgent need for a new energy storage and power generation technology that is not restricted by weather, offers high conversion efficiency, is flexible to construct, and is environmentally friendly.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 13 As shown, the present invention includes the following embodiments: Example 1: A solid water circulation energy-saving power generation system, comprising a wind turbine 11, a first-level tower body 1, one of the water impellers 3, a second-level tower body 2, another water impeller 3, a tailwater pool 21 and a circulation pool 22 connected in sequence from top to bottom; the inner diameters of the first-level tower body 1 and the second-level tower body 2 decrease in sequence from top to bottom; the water impeller 3 at the bottom of the first-level tower body 1 is connected to the first generator 12; the water impeller 3 at the bottom of the second-level tower body 2 is connected to the power conversion device 23, the speed increasing device 24, the flywheel 25 and the second generator 26; the circulation pool 22 is connected to the upper port of the first-level tower body 1 through a superimposed water pump 27; the water pump 27 is driven by the first generator 12 or the wind turbine 11; the second generator 26 is used for load and / or energy storage.

[0023] The wind turbine 11 is driven by wind to generate electricity. The electricity generated by the wind turbine 11 can drive the superimposed water pump 27 to work. The superimposed water pump 27 can also rely on the electricity generated by the first generator 12 to work. The superimposed water pump 27 pumps the water in the circulation pool 22 into the top of the first-level tower body 1. The water flows from top to bottom along the inner wall of the first-level tower body 1, so that the water converts the gravitational potential energy into electrical energy. The lower and narrower the first-level tower body 1 is, the greater the impact force of the water flow is. The water flow out of the bottom of the first-level tower body 1 will impact the water impeller 3 at the upper position. The water impeller 3 rotates under the impact of the water flow and drives the connected first generator 12 to generate electricity. The first generator 12 will use the generated electricity to drive the water pump 27 to work, and the water flow will continue to move downward and flow into the secondary tower body 2. The specifications of the inner wall of the secondary tower body 2 decrease from top to bottom, realizing water flow. The water will be discharged along the lower port of the secondary tower body 2 and impact the water impeller 3 at the lower position. The water impeller 3 will drive the force conversion device 23 to rotate through the chain, and the force conversion device 23 will drive the flywheel 25, the speed increase device 24 and the second generator 26 in turn to work, so as to realize the power generation of the second generator 26, and the electricity generated by the second generator 26 is used for storage and use; the force conversion device 23, the flywheel 25, the speed increase device 24 and the second generator 26 can be replaced by the generator set in the prior art, and it is only necessary to ensure that the water impeller 3 drives the corresponding second generator 26 to generate electricity; the water passing through the water impeller 3 at the lower position will converge into the tailwater pool 21, and the water in the tailwater pool 21 will flow into the circulation pool 22. The water in the circulation pool 22 is again filled into the upper port of the first tower body 1 under the action of the water pump 27, and so on. Hydraulic energy storage cycle power generation technology utilizes the gravitational potential energy of water in combination with a hydraulic system to achieve efficient energy storage and continuous power generation. The tower is specially designed to reach heights ranging from several to tens of meters, significantly increasing potential energy reserves. This technology forms a complete closed-loop circulation system, achieving efficient use of water resources. Its core advantage lies in its ability to generate electricity continuously around the clock, regardless of weather conditions. Through the efficient conversion of gravitational potential energy into electrical energy, its efficiency significantly outperforms traditional wind and photovoltaic power generation. Its modular tower design offers flexible deployment and can be widely used in various scenarios, including industrial plants and ships, without relying on specific natural terrain conditions. The hydraulic energy storage cycle power generation technology uses a first-stage tower 1 and a second-stage tower 2 structure to replace traditional reservoirs. Combined with the circulation of a water pump 27 and the power conversion of a water impeller 3, it utilizes the gravitational potential energy of the water body to drive power generation. The system achieves a closed-loop water cycle, eliminating water resource waste and is unaffected by weather, enabling 24-hour continuous power generation. Compared to wind and solar energy, its energy conversion efficiency is as high as over 87%, with a construction cost recovery period of only approximately two years. Its miniaturization and modularity allow for flexible deployment in industrial areas, mining areas, ships, and other scenarios, filling the gap in existing clean energy in terms of efficient, continuous power generation and miniaturized applications. Pumped storage power generation is to generate electricity by pumping and storing water, filling the gap of undeveloped projects in the field of clean energy. It has very broad development prospects and will gradually become a key project in the future new energy field. The construction cost recovery time of the tower pumped cycle power station is about two years; the construction cost recovery time of solar energy is six years; the construction cost recovery time of wind energy is 5-8 years; the tower pumped storage cycle power generation fills the gap of the national carbon neutral energy project, and the massive market "ships, aircraft carriers, 10,000-ton cargo ships, warships and other places can all build independent power stations to realize oil-to-electricity conversion, which is more conducive to ships Freedom of navigation; the pumped storage power generation projects that have been promoted and are currently being built in large quantities - frequency regulation, emergency response, energy storage, and water resource circulation storage - are not affected by weather and can generate sustainable power; the tower pumped storage circulation power generation and the national built energy storage pumped power station are based on the same principles and functions; the only difference is in certain design schemes, with independent design devices to solve the problem of water circulation power generation; the tower pumped storage circulation power station is designed as a miniaturized power station and is a truly clean and renewable energy source; it can not only protect the natural environment, save energy and protect the environment, but also make people's electricity use more convenient and worry-free; The construction cost of the tower pumped water energy storage cycle power generation project is mainly the initial station construction, while the later maintenance cost is low, without additional economic expenditure; the power generation frequency is high, with a longer life, and can continuously output electricity for a long time; the hydraulic system has a fast response speed, and the high-speed shaft pump does not require too much lubricating oil, which reduces the maintenance cost of mechanical parts; using it to generate electricity does not pollute the environment with waste water and waste residue, and is the most environmentally friendly and efficient clean energy in the world, which can reach the international level of energy conservation and emission reduction; in recent years, the world has continued to vigorously develop the development and utilization of renewable resources, and now the focus of development is energy-saving and environmentally friendly power generation projects; tower pumped water energy storage cycle It generates electricity and saves water resources, solving problems such as water loss and waste. Its power conversion rate is higher than the output power of wind and solar power. It is environmentally friendly and compact, occupies a small area, is multi-type, has flexible site conditions and no restrictions on site selection. It can use abandoned and idle mines and mines to realize distributed power generation for enterprises, factories, industrial parks, schools, etc. Among the current new energy sources, wind energy and solar energy are both natural resources (and renewable energy), but they are affected by weather and cannot achieve ideal high-quality conversion power. Tower pumped storage cycle power generation can achieve the same conversion rate of traditional electricity, more than 87%, and output considerable power. In this embodiment, the wind turbine 11 is 11500mm away from the first-level tower body, the total height of the first-level tower body 1 is 6000mm, the inner diameter of the upper end of the first-level tower body 1 is 1900mm, and the inner diameter of the lower end of the first-level tower body 1 is 160mm; the total height of the second-level tower body 2 is 10600mm, the inner diameter of the upper end of the second-level tower body 2 is 1900mm, and the inner diameter of the lower end of the second-level tower body 2 is 160mm.

[0024] Example 2: The water impeller 3 includes a central column 4 and a water receiving bucket 5 distributed on the curved outer wall of the central column 4; the front and rear end faces of the central column 4 are fixedly connected to the central rod 41; the curved outer wall of the central column 4 is fixedly connected to the radial bar 6 near the front and rear directions; multiple radial bars 6 are evenly distributed on the curved outer wall of the central column 4; multiple ends of the radial bars 6 away from the central column 4 are fixedly connected to the circular ring 7; two opposing surfaces of the circular rings 7 are penetrated by a slide groove 61; the slide groove 61 extends toward the radial bar 6; a slider 62 is slidably connected in the slide groove 61; the slider 62 is fixedly connected to the front and rear sides of the corresponding water receiving bucket 5; the water receiving bucket 5 is fixedly connected to the curved outer wall of the central column 4 through a tension spring 51; the tension of multiple tension springs 51 is different.

[0025] In this embodiment, the plurality of tension springs 51 are symmetrical about the center of the central column 4 ; the tension of two symmetrical tension springs 51 is the same, and the tension of adjacent tension springs 51 is different.

[0026] In this system, the water impeller 3 is arranged at the lower port corresponding to the first-level tower body 1 and the second-level tower body 2, and one of the water receiving buckets 5 on the water impeller 3 is aligned with the lower port of the first-level tower body 1 and the second-level tower body 2, so that after the water flow hits the water receiving bucket 5, it can drive the water impeller 3 to rotate. The number of receiving buckets for the water impeller 3 in this system is fixed; the water impeller 3 at the lower port of the first-level tower body 1 and the second-level tower body 2 in this system faces the problem of poor adaptability between the water flow energy and the working state of the water impeller 3 when running; on the one hand, when the system is started, since the number of water receiving buckets 5 fixedly arranged on the edge of the water impeller 3 is fixed and is at the edge position, a large resistance torque needs to be overcome during startup, resulting in startup difficulties and increased energy consumption; on the other hand, during the operation of the system, the water flows from the first-level tower body 1 to the second-level tower body 2. When the water flows to the secondary tower body 2, the flow velocity and flow rate change, and the traditional fixed number of impact-driven blades is difficult to adapt to the water flow energy under different working conditions; when the water flow energy is insufficient, the excessive number of water receiving buckets 5 cannot effectively utilize the limited kinetic energy, resulting in energy waste; and when the water flow energy is strong, the number of water receiving buckets 5 cannot be dynamically increased, and the water flow energy cannot be fully captured, resulting in low power generation efficiency and inability to achieve efficient energy circulation between electric energy-driven pumping and hydropower generation in the system; in addition, there is a lack of an effective mechanism that can dynamically adjust the number and position of the impact-driven water receiving buckets 5 according to the rotation speed of the water impeller 3, making it difficult for the water impeller 3 to always maintain the optimal working state under different water flow conditions, seriously restricting the improvement of the overall performance and stable operation of the solid water cycle energy-saving power generation system; In the present embodiment, a smaller number of water receiving buckets 5 are initially kept at the edge of the water impeller 3, so that a part of the water receiving buckets 5 of the water impeller 3 are located near the center of the water impeller 3, reducing the resistance to the rotation of the water impeller 3, thereby facilitating the driving of the water impeller 3; for the sake of convenience in description, the water receiving buckets 5 located at the edge of the water impeller 3 and capable of being impacted by the water flow are referred to as enabled water receiving buckets 5, and the water receiving buckets 5 near the center of the water impeller 3 are referred to as disabled water receiving buckets 5. After the water flow impacts the enabled water receiving buckets 5, the enabled water receiving buckets 5 will transmit the impact force to the circular ring 7, and the circular ring 7 will transmit the force to the radial bars 6, thereby driving the central column 4 and the central rod 41 to rotate through the radial bars 6, and the rotation process of the central rod 41 The first generator 12 or the second generator 26 will be driven to generate electricity. During the overall rotation of the water impeller 3, the disabled water receiving bucket 5 will be affected by the centrifugal force. The greater the rotation speed of the water impeller 3, the greater the centrifugal force received by the water receiving bucket 5, and the more the disabled water receiving bucket 5 is active. Under the action of the centrifugal force, the disabled water receiving bucket 5 drives the slider 62 to move along the slide 61 away from the center column 4. In the process of the disabled water receiving bucket 5 moving away from the center column 4, the tension of the tension spring 51 will be overcome. When the disabled water receiving bucket 5 moves to the inside of the ring 7, the disabled water receiving bucket 5 will be converted into the enabled water receiving bucket 5. The tension of multiple tension springs 51 is different. The higher the rotation speed of the water impeller 3, the greater the centrifugal force, and the more the number of enabled water receiving buckets 5 is. Furthermore, the two centrally symmetrical tension springs 51 have the same tension force, achieving synchronous activation and deactivation, thereby making the rotation of the water impeller 3 more balanced, avoiding instability of the center of gravity and energy loss caused by deviation in one direction, and improving the rotation efficiency of the water impeller 3. In addition, the number of water receiving buckets 5 in this embodiment is customized according to needs and the diameter of the water impeller 3, and is not limited to the number shown in the accompanying drawings. The water impeller 3 in this embodiment can adapt to the water flow energy. When the water flow speed is fast and the energy is large, the speed of the water impeller 3 is accelerated, and the water receiving buckets 5 move to the edge under the action of centrifugal force, and the number increases, which can make fuller use of the powerful water flow energy and improve the working ability of the water impeller 3; when the water flow speed is slow and the energy is small, the speed of the water impeller 3 is reduced, and the water receiving buckets 5 gather towards the center and the number decreases, which can avoid the water impeller 3 from rotating too hard due to too many water receiving buckets 5, so that the water impeller 3 can maintain a good operating state under different water flow conditions, thereby ensuring the stability of power generation; the water impeller 3 in this embodiment has high efficiency and stability, and the number of water receiving buckets 5 is automatically adjusted with the speed, which can make the water The impeller 3 maintains a relatively reasonable stress state and energy conversion efficiency under different working conditions, reducing energy loss. This adaptive adjustment helps to maintain the stability of the rotation of the water impeller 3, reduce the speed fluctuation caused by changes in water flow, make the water impeller 3 run more smoothly and reliably, and extend the service life of the water impeller 3; the simplified control mechanism of the water impeller 3 in this embodiment does not require a complex external control system to adjust the number of water receiving buckets 5, and can achieve automatic adjustment of the number of water receiving buckets 5 only by relying on the natural physical phenomenon of centrifugal force, which reduces the design and manufacturing costs of the water impeller 3, and also reduces the possible failure points due to complex control systems, thereby improving the overall reliability and ease of use of the water impeller 3.

[0027] Example 3: An adjustment groove 42 is provided inside the center column 4; an adjustment disk 43 is connected to the sliding seal inside the adjustment groove 42; a threaded hole 44 is provided on the end face of the center column 4 in communication with the adjustment groove 42; an adjustment bolt 45 is threadedly connected to the threaded hole 44; the adjustment disk 43 divides the internal space of the adjustment groove 42 into a plug chamber 421 and a plug-free chamber 422; a folding sleeve 8 is connected between the curved outer wall of the center column 4 and the water receiving bucket 5; a plurality of the folding sleeves 8 are nested in each other and movably sealed; the innermost folding sleeve 8 is fixedly connected to the curved outer wall of the center column 4, and the outermost folding sleeve 8 is fixedly connected to the outer wall of the water receiving bucket 5; the innermost folding sleeve 8 is connected to the plug chamber 421 through the liquid hole 81.

[0028] The adjusting screw 45 is screwed in the threaded hole 44 and moves along the axial direction of the adjusting screw 45. The forward or reverse screwing can change the direction of movement of the adjusting screw 45. When the adjusting screw 45 is inserted into the adjusting slot 42 for a longer time, the movement of the adjusting disc 43 in the adjusting slot 42 is more restricted, so that the minimum space in the plug cavity 421 is larger. The plug cavity 421 refers to the cavity with the adjusting screw 45. During the rotation of the water impeller 3, the deactivated water receiving bucket 5 will overcome the corresponding tension spring 51 and move away from the center column 4 under the action of centrifugal force. The multiple retractable sleeves 8 will expand as the water receiving bucket 5 moves away from the center column 4. During the expansion of the multiple retractable sleeves 8, negative pressure is formed on the inner side, so that the liquid medium in the plug cavity 421 flows into the inner side of the multiple expanded retractable sleeves 8 along the liquid hole 81 under the action of negative pressure. Until the corresponding number of deactivated water receiving buckets 5 are converted into activated water receiving buckets 5, the adjusting disc 43 moves along The adjusting groove 42 slides and contacts the adjusting bolt 45, and the adjusting bolt 45 limits the plug chamber 421 from continuing to decrease, which also makes it difficult to increase the number of activated water receiving buckets 5; when the speed of the water impeller 3 decreases, the tension spring 51 will activate the water receiving bucket 5 to approach the center column 4 and convert it into an inactive water receiving bucket 5, and the multiple folding sleeves 8 will fold each other, and the liquid medium inside the multiple folding sleeves 8 will flow back into the plug chamber 421 along the liquid hole 81, and the space inside the plug chamber 421 becomes larger; in this embodiment, when the number of folding sleeves 8 is greater, the axial length of the folding sleeve 8 is shorter while maintaining the requirement of expanding the multiple folding sleeves 8, so that the inactive water receiving bucket 5 is closer to the center column 4, so that the inactive water receiving bucket 5 has less influence on the rotational resistance of the water impeller 3; in this embodiment, by screwing the adjusting bolt 45, the movable position of the adjusting disk 43 in the adjusting groove 42 is limited, thereby limiting the maximum activated number of water receiving buckets 5 in the water impeller 3, thereby meeting the usage requirements in different environments.

[0029] Example 4: The water receiving bucket 5 has a semi-cylindrical shape; the water receiving bucket 5 is rotatably sealed and connected to the tipping bucket 9; the tipping bucket 9 has the same shape as the water receiving bucket 5; the tipping bucket 9 is rotatably connected to the slider 62 via a tipping shaft 91; one of the groove walls of the slide 61 is provided with a first tooth groove 63; a rack 64 is provided in the first tooth groove 63 (simplified in the figure); the slider 62 is provided with a second tooth groove 65 on the side facing the first tooth groove 63; the second tooth groove 65 is rotatably connected to a cylindrical gear 66 (simplified in the figure) that meshes with the rack 64 for transmission; the cylindrical gear 66 is fixedly connected to the end of the tipping shaft 91.

[0030] In this embodiment, the second tooth groove 65 is rotatably connected to the transition gear 67 ; the cylindrical gear 66 is meshed with the rack 64 through the transition gear 67 (simplified in the figure); the number of teeth of the cylindrical gear 66 is smaller than that of the transition gear 67 .

[0031] When the water collecting bucket 5 is in a closed position, the water collecting bucket 5 is turned over by the gear 62 and the gear 66 is in engagement with the rack 64, so that the gear 66 rotates and drives the tipping shaft 91 to rotate. When the tipping shaft 91 rotates, the tipping bucket 9 is turned over. When the water collecting bucket 5 is in a closed position, the water collecting bucket 5 is turned over by the gear 62 and the rack 64 is in engagement with the rack 64. When the water collecting bucket 5 is in a closed position, the water collecting bucket 5 is turned over by the gear 66 and the rack 64. The gears 64 and 66 are similar to cylinders, so that when the water receiving bucket 5 is activated to receive water, the water flow will not impact and splash on the inactive water receiving bucket 5, reducing the influence of the water flow on the rotation of the inactive water receiving bucket 5, making the rotation of the water impeller 3 smoother and more stable; further, since the cylindrical gear 66 is meshed with the rack 64 through the transition gear 67 for transmission, the number of teeth of the transition gear 67 is greater than that of the cylindrical gear 66, so the transition gear 67 drives the cylindrical gear 66 to rotate more effortlessly, making the tipping bucket 9 more effortlessly rotated, thus making the slider 62 slide more sensitively in the chute 61; in this embodiment, the teeth of the rack 64, rack 64 and cylindrical gear 66 shown in the accompanying drawings only represent the meshing state, and do not represent the flipping angle of the tipping bucket 9. The tipping bucket 9 is guaranteed to be located at the end of the chute 61 away from the center column 4 to open the water receiving bucket 5, and the tipping bucket 9 is guaranteed to be located at the end of the chute 61 close to the center column 4 to block the water receiving bucket 5.

[0032] Example 5: When the slider 62 moves along the chute 61 toward the center column 4 , the tipping bucket 9 will start to flip from the position where the water receiving bucket 5 is close to the center column 4 .

[0033] As the slider 62 approaches the center column 4, the activated water receiving bucket 5 will be transformed towards the disabled water receiving bucket 5, and the tipping bucket 9 will flip over under the drive of the cylindrical gear 66. The tipping bucket 9 will first flip over from a position close to the center column 4, so that the remaining water in the water receiving bucket 5 can flow out along the edge gap of the water receiving bucket 5 away from the center column 4, avoiding water flow remaining inside the disabled water receiving bucket 5.

[0034] Example 6: The non-bolt cavity 422 is connected to the outside through the one-way air inlet 46 ; the non-bolt cavity 422 is connected to the bottom of the first tooth groove 63 through the one-way air outlet 47 .

[0035] In this embodiment, an annular groove 71 is provided on the outer wall of the circular ring 7; the outer edge of the circular ring 7 is rotatably sealed and connected to a swivel 72; the center of gravity of the swivel 72 is at the bottom; and a through hole 73 is provided on the top of the swivel 72.

[0036] When the speed of the impeller 3 increases, the slider 62 moves away from the center column 4 along the slide groove 61, the adjusting disk 43 slides in the adjusting groove 42 and squeezes the bolt cavity 421, the space in the bolt-free cavity 422 becomes larger to form a negative pressure, and the outside gas enters the bolt-free cavity 422 along the one-way air inlet 46 to replenish the gas. When the speed of the impeller 3 decreases, the slider 62 moves closer to the center column 4 along the slide groove 61, the adjusting disk 43 slides in the adjusting groove 42 and squeezes the bolt-free cavity 422, and the space in the bolt-free cavity 422 becomes smaller, and the gas in the bolt-free cavity 422 is replenished. It is discharged along the one-way air outlet 47 to impact the first tooth groove 63, so as to clean the impurities in the first tooth groove 63 and ensure the stable transmission of the rack 64; further, the outer edge of the circular ring 7 is rotated and sealed to connect the swivel 72, so in the process of the space in the bolt-free cavity 422 becoming larger, the through hole 73 on the swivel 72 will form a negative pressure, and the through hole 73 is away from the center of gravity of the swivel 72. The position of the through hole 73 is always located at the top of the water impeller 3 to reduce the probability of the bolt-free cavity 422 sucking in liquid, so that only the airflow can impact the impurities in the first tooth groove 63.

[0037] Example 7

[0038] The water impeller includes a wheel shell 31, a runner 32, a rotating shaft 33 and a water bucket body 34; a trigger block 35 is provided on the side wall of the wheel shell 31; a reset bar 36 is provided at the bottom of the wheel shell 31; the runner 32 is rotatably connected to the wheel shell 31 through the rotating shaft 33; the water bucket body 34 is evenly rotatably connected to the edge of the runner 32 through the water bucket shaft 37; the inner wall of the runner 32 is fixedly connected to a limit block 38 for limiting the position of the water bucket body 34 after it is unfolded; a trigger bar 39 is externally provided at the end of the water bucket shaft 37; the water bucket body 34 is unfolded when the trigger bar 39 contacts the trigger block 35, and the water bucket body 34 is retracted when the water bucket body 34 contacts the reset bar 36.

[0039] The wheel 32 is rotatably connected to the inner side of the wheel housing 31 through the rotating shaft 33. The wheel housing 31 is a shell-shaped container for holding water. A trigger block 35 is fixedly connected to the vertical inner wall of the wheel housing 31. Taking the movement of one of the water bucket bodies 34 as an example, the folded water bucket body 34 at the top moves synchronously with the rotation of the wheel 32. After the trigger bar 39 contacts the trigger block 35, it will be compressed to drive the water bucket shaft 37 to rotate. The water bucket shaft 37 is fixedly connected to the water bucket body 34, so it drives the water bucket body 34 to flip outward, realizing the transition from the folded state to the unfolded state. The handle part of the unfolded water bucket body 34 is limited by the limit block 38, thereby maintaining the unfolded state of the water bucket body 34. The opening of the unfolded water bucket body 34 faces the water falling position to collect water. The water bucket body 34 realizes the conversion of gravitational potential energy into kinetic energy under the impact of the water flow. As the impeller 32 rotates, the body 34 will contact the reset bar 36 at the bottom of the wheel shell 31, thereby pushing the water bucket body 34 to flip inward and reset. The end of the water bucket body 34 away from the water bucket shaft 37 will abut against the adjacent limit block 38 to achieve limit. As the water bucket body 34 continues to move upward, the water bucket body 34 always remains in the retracted state until the next time the corresponding trigger bar 39 is triggered again by the trigger block 35 and then unfolded, and this process is repeated; during the rotation of the rotating shaft 33, the corresponding first generator 12 or second generator 26 will be driven to generate electricity; by unfolding the water bucket body 34 at the water receiving position and retracting the water bucket body 34 away from the water receiving position, the air resistance at the non-water receiving position is reduced, the rotation efficiency of the impeller 32 is improved, and the structural instability caused by shaking is avoided. By reducing these influences, the impeller 32 can rotate more effectively and the rotation torque is increased.
