Description

Technical Field

[0001] This invention relates to the field of water gravity power generation technology, specifically a three-dimensional multi-stage water gravity power generation device. Background Technology

[0002] Against the backdrop of energy structure transformation and upgrading, the development and utilization of clean energy has become a global focus. Hydropower, as a mature clean energy generation method, has been widely used due to its advantages of being pollution-free and renewable.

[0003] Traditional water gravity power generation devices mostly adopt a single-stage water turbine structure, which has low efficiency in utilizing the gravitational potential energy of water. In addition, the device layout is mostly planar, which occupies a lot of land resources and has obvious defects in space utilization. At the same time, the transmission structure design of some water gravity power generation devices is unreasonable, and the mechanical energy transmission process of water turbine rotation has large losses, making it difficult to efficiently convert it into electrical energy. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a three-dimensional multi-stage water gravity power generation device. This addresses the problems of traditional water gravity power generation devices, which mostly employ a single-stage water turbine structure, resulting in low utilization efficiency of water gravity potential energy. Furthermore, these devices are often planar in layout, occupying significant land resources and exhibiting obvious deficiencies in space utilization. Additionally, some water gravity power generation devices suffer from unreasonable transmission structure designs, leading to substantial losses during the mechanical energy transmission process of the rotating water turbine, making it difficult to efficiently convert the energy into electrical energy.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a three-dimensional multi-stage water gravity power generation device, comprising a water tank and a water pump. A fixed frame is installed inside the water tank. Turbine housings are uniformly fixedly connected inside the fixed frame. Turbine shafts are rotatably connected inside the turbine housings. A coupling is provided at one end of each of the two turbine shafts facing each other. Turbine blades are uniformly fixedly connected to the outer walls of the turbine shafts. A guide pipe is fixedly connected to one side of each of the two turbine housings facing each other. A pumping pipe is fixedly connected to the input end of the water pump. A conveying pipe is fixedly connected to the output end of the water pump. Outlet pipes are symmetrically fixedly connected to the outer walls of the conveying pipes. The bottom end of the outlet pipe is fixedly connected to the outer wall of the top turbine housing. A connecting pipe is fixedly connected to the bottom of each of the two bottom turbine housings. The bottom end of the connecting pipe is fixedly connected to the outer wall of the pumping pipe. Support plates are uniformly fixedly connected inside the fixed frame. A speed increaser is installed on the top of each support plate.

[0006] By adopting the above technical solution, a multi-stage water gravity work structure is formed by setting up a three-dimensional multi-layered water turbine structure and a guide pipe to replace the traditional single-stage water turbine and planar layout. This greatly improves the utilization rate of water gravity potential energy, while effectively saving land resources and improving space utilization efficiency. The power generation can be increased by increasing the number and height of the turbine layers. The power generation increases several times with each additional layer. At the same time, the torque force and water weight of the turbine can be increased by widening and adding sections, which further improves the power generation capacity. By setting up a high-torque water turbine with a speed-increasing structure with a speed ratio of 1:300, the efficient conversion of mechanical energy of water turbine rotation into electrical energy is achieved, which greatly reduces the loss in the mechanical energy transmission process and effectively improves the power generation and efficiency of the device. Water flowing through the bottom turbine casing returns to the pumping pipe via a connecting pipe, then flows into the pool via the pumping pipe, where it is pumped out and transported again, forming a water resource recycling system to achieve continuous power generation.

[0007] Preferably, the turbine casing is distributed in multiple equidistant layers inside the fixed frame, and each layer of the turbine casing has at least two casings.

[0008] Preferably, a coupling is rotatably connected to the end of the transmission shaft one on one side of the speed increaser and the end of the turbine shaft opposite to it.

[0009] Preferably, a generator is mounted on the top of the support plate, and a rotating shaft is fixedly connected to the output end of the generator.

[0010] Preferably, a coupling is provided at the opposite end of the transmission shaft two and the rotating shaft on the other side of the speed increaser.

[0011] Preferably, both of the outlet pipes are equipped with a water level controller.

[0012] Preferably, sealing gaskets are provided at the connection points between the outlet pipe and the turbine casing, and between the connecting pipe and the pumping pipe.

[0013] Preferably, the turbine blades have an arc-shaped structure, and the turbine blades are distributed in a ring array on the outer wall of the turbine shaft.

[0014] Preferably, the turbine casing is composed of a left half casing, a right half casing, a left wall panel, and a right wall panel.

[0015] Working principle: During operation, the water pump is started, drawing water from the pool through the pumping pipe. The water is then transported through the delivery pipe into two outlet pipes. The water in the outlet pipes flows into the turbine casing at the top. The water level controller in the outlet pipes adjusts the water inflow in real time to balance the weight of the water and the torque of the turbine, thus achieving balance in the power generation system. The water then flows through the guide pipes into the lower turbine casings. The water flows between the multiple turbine casings through the guide pipes, repeatedly impacting the turbine blades using gravitational potential energy. The turbine casings are always kept at one side with half water. The continuous weight difference drives the turbine shaft of the high-torque turbine to rotate, converting the gravitational potential energy of the water into mechanical energy. The rotation of the turbine shaft drives the transmission shaft of the speed increaser to rotate through coupling two, transmitting mechanical energy to the speed increaser. The speed increaser converts the low-speed, high-torque rotation of the turbine into high-speed rotation with a speed increase ratio of :, thus optimizing the rotational speed of the mechanical energy. The speed increaser drives the rotating shaft to rotate through the cooperation of transmission shaft two and coupling three, transmitting high-speed mechanical energy to the generator. The generator converts the received mechanical energy into electrical energy, realizing the final energy output. Water flowing through the bottom turbine casing returns to the pumping pipe through the connecting pipe, and then flows into the pool through the pumping pipe. It is then pumped out and transported again by the water pump, forming a water resource recycling system to achieve continuous power generation. Increase the number and height of the turbine layers to increase power generation. The power generation increases several times with each additional layer. At the same time, the torque and water weight of the turbine are increased by widening and adding sections, further improving the power generation capacity.

[0016] This invention provides a three-dimensional multi-stage water gravity power generation device. It has the following beneficial effects: 1. This invention, by setting up a three-dimensional multi-layered water turbine structure in conjunction with a guide pipe to form a multi-stage water gravity work structure, replaces the traditional single-stage water turbine and planar layout, greatly improving the utilization rate of water gravity potential energy, while effectively saving land resources and improving space utilization efficiency.

[0017] 2. This invention increases power generation by increasing the number and height of the turbine layers. The power generation increases several times with each additional layer. At the same time, the torque force and water weight of the turbine are increased by widening and adding sections, further improving the power generation capacity.

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 -Appendix Figure 7This invention provides a three-dimensional multi-stage water gravity power generation device, including a water tank 20 and a water pump 2. A fixed frame 1 is installed inside the water tank 20. A turbine housing 5 is uniformly fixedly connected inside the fixed frame 1. A turbine shaft 7 is rotatably connected inside the turbine housing 5. A coupling 11 is provided at one end of the two turbine shafts 7 facing each other. Turbine blades 8 are uniformly fixedly connected to the outer wall of the turbine shafts 7. A guide pipe 6 is fixedly connected to one side of the two turbine housings 5 ​​facing each other. A pumping pipe 3 is fixedly connected to the input end of the water pump 2. A conveying pipe 4 is fixedly connected to the output end of the water pump 2. Outlet pipes 9 are symmetrically fixedly connected to the outer wall of the conveying pipe 4. The bottom end of the outlet pipe 9 is fixedly connected to the outer wall of the top turbine housing 5. A connecting pipe 10 is fixedly connected to the bottom of the two bottom turbine housings 5. The bottom end of the connecting pipe 10 is fixedly connected to the outer wall of the pumping pipe 3. A support plate 13 is uniformly fixedly connected inside the fixed frame 1. A speed increaser 14, model T8, is installed on the top of the support plate 13.

[0024] Specifically, water pump 2 is started, drawing water from pool 20 through pumping pipe 3, and then conveying the water through conveying pipe 4 into two outlet pipes 9. The water in outlet pipes 9 flows into the turbine casing 5 at the top. The water level controller in outlet pipes 9 adjusts the water inflow in real time to balance the weight of the water and the torque of the turbine, thus achieving balance in the power generation system. The water then flows through guide pipe 6 into the lower turbine casing 5. The water flows between the multiple turbine casings 5 ​​through guide pipe 6, repeatedly impacting the turbine blades 8 using gravitational potential energy. The turbine casing 5 always maintains a state where one side contains half water, forming a continuous weight difference that drives the turbine shaft 7 of the high-torque turbine to rotate, converting the gravitational potential energy of the water into mechanical energy. The rotation of the turbine shaft 7... The transmission shaft 15 of the speed increaser 14 is driven to rotate by the coupling 2 12, which transmits mechanical energy to the speed increaser 14. The speed increaser 14 converts the low-speed, high-torque rotation of the water turbine into high-speed rotation with a speed increase ratio of 1:300, thus optimizing the rotational speed of the mechanical energy. The speed increaser 14 drives the rotating shaft 18 to rotate through the cooperation of the transmission shaft 2 16 and the coupling 3 19, which transmits the high-speed mechanical energy to the generator 17. The generator 17 converts the received mechanical energy into electrical energy, thus realizing the final output of energy. By setting up a three-dimensional, multi-layered water turbine structure and cooperating with the guide pipe 6 to form a multi-stage water gravity work structure, it replaces the traditional single-stage water turbine and planar layout, which greatly improves the utilization rate of water gravity potential energy, while effectively saving land resources and improving space utilization efficiency. Water flowing through the bottom turbine casing 5 returns to the pumping pipe 3 through the connecting pipe 10, and then flows into the water tank 20 through the pumping pipe 3. It is then pumped and transported again by the water pump 2, forming a water resource recycling system to achieve continuous power generation. By installing a water level controller in the outlet pipe 9, the weight and torque of the water entering the turbine can be precisely adjusted to achieve dynamic balance of the power generation system, ensuring that the equipment is always in a stable operating state and avoiding equipment failure and energy loss due to water imbalance. The power generation can be increased by increasing the number and height of the turbine layers. The power generation increases several times with each additional layer. At the same time, the torque force and water weight of the turbine can be increased by widening and adding sections, which further improves the power generation capacity. By setting up a high-torque turbine with a speed-increasing structure with a speed ratio of 1:300, the efficient conversion of mechanical energy of the turbine rotation into electrical energy is achieved, which greatly reduces the loss in the mechanical energy transmission process and effectively improves the power generation and efficiency of the device.

[0025] Please refer to the appendix. Figure 4 -Appendix Figure 5 The turbine casing 5 is distributed in multiple layers at equal intervals inside the fixed frame 1, and each layer of the turbine casing 5 has at least two units.

[0026] Specifically, a multi-stage water gravity work structure is formed by multi-layered distributed water turbines. Water flows from top to bottom through the outer shell of each water turbine layer 5, so that the gravitational potential energy of water can be converted into the mechanical energy of water turbine rotation in each layer. This avoids the drawback of a single-stage water turbine only being able to utilize potential energy once, and realizes the tiered and full utilization of water gravitational potential energy, greatly improving the overall potential energy conversion efficiency.

[0027] Please refer to the appendix. Figure 1 -Appendix Figure 3 Appendix Figure 6 -Appendix Figure 7 On one side of the speed increaser 14, the transmission shaft 15 and the turbine shaft 7 are rotatably connected to a coupling 12. A generator 17 is installed on the top of the support plate 13. The output end of the generator 17 is fixedly connected to a rotating shaft 18. On the other side of the speed increaser 14, the transmission shaft 16 and the rotating shaft 18 are connected to a coupling 19.

[0028] Specifically, when the turbine shaft 7 rotates due to the gravitational potential energy of the water flow, the rotation of the turbine shaft 7 is transmitted through coupling 2 12 to the transmission shaft 15 on one side of the speed increaser 14, inputting mechanical energy into the speed increaser 14. The speed increaser 14 completes the conversion from low speed and high torque to high speed rotation at a speed increase ratio of 1:300, and then outputs high-speed mechanical energy through the transmission shaft 2 16 on the other side. The rotational power is then transmitted through coupling 3 19 to the rotating shaft 18 of the generator 17, transmitting the high-speed mechanical energy to the generator 17. The generator 17 converts the received mechanical energy into electrical energy, realizing the efficient conversion of mechanical energy from the turbine to the generator 17, reducing the loss in the mechanical energy transmission process, and effectively improving the power generation power and efficiency of the device.

[0029] Please refer to the appendix. Figure 3 Appendix Figure 6 Appendix Figure 7 Both outlet pipes 9 are equipped with water level controllers.

[0030] Specifically, by setting a water level controller in the outlet pipe 9, the amount of water entering the top turbine casing 5 can be adjusted in real time to accurately match the power demand of the turbine, so that the weight of the water and the torque of the turbine rotation are always in a dynamic balance. This avoids the turbine torque from being too high due to excessive water, which could cause component overload, and also prevents insufficient water from causing insufficient torque and turbine idling, thus ensuring the force balance and stable operation of the power generation system.

[0031] Please refer to the appendix. Figure 4 -Appendix Figure 5 Sealing gaskets are provided at the connection points between the outlet pipe 9 and the turbine casing 5, and between the connecting pipe 10 and the pumping pipe 3. The turbine blades 8 have an arc-shaped structure and are arranged in a ring array on the outer wall of the turbine shaft 7.

[0032] Specifically, the sealing gasket fills the gaps between the pipe and the shell, and between the pipes, to prevent water from leaking out of the joints. This allows all the water pumped by the pump 2 to enter the turbine shell 5 and impact the turbine blades 8 to do work, eliminating water energy waste caused by leakage and ensuring that each turbine blade 8 receives sufficient water impact, maximizing the exploitation of the gravitational potential energy of the water and improving the overall energy conversion efficiency. Compared to straight blades, the curved surface design of turbine blade 8 allows for a larger contact area with the water flow. The curved surface can also guide the water flow, allowing the gravitational impact force of the water flow to act more evenly on the blades. This avoids the energy waste caused by the water flow quickly sliding over the blade surface, and fully captures water energy and converts it into the driving force that drives the blades to rotate. The curved blade structure design can efficiently convert the vertical gravitational impact force of the water flow into the circumferential torque that drives the turbine shaft 7 to rotate, reduce the loss of the reaction force of the water flow impact, and allow water energy to be converted into the rotational mechanical energy of the turbine shaft 7 more directly and efficiently, thereby improving the energy conversion efficiency of the single-stage turbine structure and thus improving the power generation efficiency of the entire device. The turbine blades are solid on both sides, and the connection gap between the turbine blades 8 and the left and right outer shells is strictly controlled at 0.3mm. This structure forms water flow protection to prevent excessive water loss and ensure that the gravitational potential energy of the water always acts on the turbine blades 8, avoiding energy loss and ensuring the working efficiency and torque stability of the turbine.

[0033] Please refer to the appendix. Figure 1 -Appendix Figure 7 The turbine casing 5 consists of a left half casing, a right half casing, a left wall panel 501, and a right wall panel 502.

[0034] Specifically, compared to a one-piece turbine casing, the separate design of the left and right halves of the casing, the left wall panel 501, and the right wall panel 502 allows the installation of core internal components such as the turbine shaft 7 and turbine blades 8 without having to be inserted from the end of the casing. The turbine shaft 7 and turbine blades 8 can be assembled first, and then the left and right halves of the casing can be fastened together and fixed with the left wall panel 501 and the right wall panel 502. This greatly simplifies the assembly process of internal components and reduces the overall installation difficulty of the equipment. At the same time, it facilitates later maintenance and component replacement, reducing operation and maintenance costs.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
