Description

Technical Field

[0001] This utility model belongs to the field of wind power generation technology, and specifically relates to a wind power generation water storage energy storage system. Background Technology

[0002] Wind power generation is a new energy source that converts wind energy into electricity. After generating electricity, the wind power equipment needs to store it. Currently, common storage methods include pumped hydro storage and battery storage. Pumped hydro storage uses electricity to power a pump that pumps water to an upstream reservoir or tank. When electricity is needed, the water is released, and the water pressure drives a turbine generator to generate electricity. However, during this process, low water levels in the reservoir or tank cause a drop in water pressure, reducing the speed of the turbine generator's impeller. If the water pressure is too low, the impeller cannot rotate at all, affecting the generator's efficiency and hindering stable power generation. Utility Model Content

[0003] This utility model provides a wind power generation water storage system, which aims to solve the problem of unstable performance affecting power generation efficiency in existing wind power generation water storage systems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a wind power generation and water storage energy storage system, comprising: Wind turbine; A water pump, wherein the wind turbine is used to supply power to the water pump; A water storage tank is connected to the outlet end of the water pump; A booster tank is connected to the top of the water storage tank, and a booster mechanism is installed inside the booster tank; A water storage tank is installed below the water storage tank; An impeller generator is connected to the bottom of the water storage tank and the top of the water storage silo. A control valve for controlling the working status is installed at the liquid inlet end of the impeller generator.

[0005] In one possible implementation, the pressurization mechanism includes: The piston cylinder is connected to the pressurization tank and is arranged in a vertical direction; The piston rod has a piston portion that is slidably disposed inside the piston cylinder fixedly installed at its end, and a gravity block is fixedly installed at the top of the piston rod.

[0006] In one possible implementation, there are multiple piston cylinders, all of which are fixedly installed on the top of the pressurizing tank and are evenly spaced along the circumference of the pressurizing tank.

[0007] In one possible implementation, a connecting plate is slidably mounted on the top of the pressurization tank in a vertical direction, and the piston rods corresponding to the plurality of piston cylinders are all fixedly mounted on the connecting plate.

[0008] In one possible implementation, a support rod for mounting a gravity block is fixedly installed on the connecting plate, the gravity block is fitted onto the support rod, and a limiting sleeve for preventing the gravity block from sliding out of the support rod is detachably installed on the support rod.

[0009] In one possible implementation, a plurality of support rods are fixedly mounted on the connecting plate, the number of support rods corresponding one-to-one with the number of piston rods, and each support rod is coaxially arranged with the corresponding piston rod.

[0010] In one possible implementation, a pressure relief valve is connected to the bottom of the pressure booster tank, and the outlet of the pressure relief valve is connected to the water storage tank.

[0011] In one possible implementation, a pressure boosting pipe is connected to the water storage tank or the pressure boosting tank, and a switch valve for controlling the flow state is installed on the pressure boosting pipe.

[0016] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Please refer to the following: Figures 1 to 3 The wind power generation and water storage energy storage system provided by this utility model will now be described. The wind power generation and water storage energy storage system includes a wind turbine generator 1, a water pump 2, a water storage tank 3, a booster tank 4, a water storage silo 5, and a turbine generator 6. The wind turbine generator 1 supplies power to the water pump 2; the water storage tank 3 is connected to the outlet end of the water pump 2; the booster tank 4 is connected to the top of the water storage tank 3, and a booster mechanism is installed inside the booster tank 4; the water storage silo 5 is installed below the water storage tank 3; the turbine generator 6 is connected to the bottom of the water storage tank 3 and the top of the water storage silo 5, and a control valve 61 for controlling the working state is installed at the inlet end of the turbine generator 6.

[0018] The wind power generation and water storage energy storage system provided in this embodiment, compared with the prior art, uses a wind turbine generator 1. After the electricity generated by the wind turbine generator 1 is used for normal power supply, the excess electricity is supplied to a water pump 2, which pumps water from the water storage tank 5 into the water storage tank 3. Both the water storage tank 3 and the booster tank 4 are sealed tank structures. Energy is stored by pumping water from the water storage tank 5 into the water storage tank 3. During later power supply, the control valve 61 corresponding to the liquid inlet end of the impeller generator 6 below the water storage tank 3 can be opened. This allows water from the water storage tank 3 to flow into the impeller generator 6, driving the impeller to rotate and generate electricity. In this application, a booster tank 4 is connected to one side of the water storage tank 3. A booster mechanism is installed inside the booster tank 4. The booster mechanism can increase the pressure inside the booster tank 4 and the water storage tank 3, ensuring that the water storage tank 3 has sufficient water pressure to drive the impeller generator 6 to generate electricity during water discharge, ensuring stable power generation and improving power generation efficiency.

[0019] Preferably, in this embodiment, when the water storage tank 3 and the booster tank 4 are initially empty, the pressure inside the booster tank 4 and the water storage tank 3 can be increased by the booster mechanism. When the water pump 2 pumps the water source inside the water storage tank 5 into the water storage tank 3, the water storage tank 3 remains in a state of stable pressure or increased pressure. Thus, when the water storage tank 3 is draining water, a certain draining pressure can be maintained, which can effectively drive the impeller generator 6 to generate electricity and improve the power generation efficiency.

[0020] Specifically, in this embodiment, the method and means of supplying power from the wind turbine generator 1 to the water pump 2 are existing technologies and will not be described further here.

[0021] In some embodiments, the aforementioned pressurization mechanism may employ, for example... Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 The pressurization mechanism includes a piston cylinder 41 and a piston rod 42. The piston cylinder 41 is connected to the pressurization tank 4 and is arranged vertically. A piston portion that is slidably disposed inside the piston cylinder 41 is fixedly installed at the end of the piston rod 42, and a gravity block 43 is fixedly installed at the top of the piston rod 42. The piston cylinder 41 is connected to the top of the pressurization tank 4 and is sealed to the pressurization tank 4. The piston rod 42 is slidably disposed inside the piston cylinder 41, and a piston that is slidably disposed on the inner wall of the piston cylinder 41 is installed in the middle of the piston rod 42. The piston seals the bottom of the piston cylinder 41 with the outside, preventing gas leakage from the pressurization tank 4.

[0022] Specifically, in this embodiment, during actual application, the top of the booster tank 4 and the water storage tank 3 are connected, and both the booster tank 4 and the water storage tank 3 are closed structures. When the water pump 2 pumps the water inside the water storage tank 5 into the water storage tank 3, the internal pressure of the water storage tank 3 and the booster tank 4 increases. When the internal pressure of the booster tank 4 can push the piston rod 42 to move upward, the upward movement of the piston rod 42 makes the internal pressure of the water storage tank 3 and the booster tank 4 tend to stabilize. When the water storage tank 3 releases water to generate electricity for the impeller generator 6, the water source inside the water storage tank 3 is lost, and the piston rod 42 moves downward under the action of the gravity block 43, thereby maintaining a stable pressure inside the water storage tank 3, thus ensuring the stability of the water pressure flowing into the impeller generator 6.

[0023] Preferably, in this embodiment, the water storage tank 3 and the booster tank 4 always maintain a certain pressure, thereby ensuring that the water storage tank 3 always has a certain pressure during the water discharge process, ensuring that the impeller on the impeller generator 6 can have a stable speed, and ensuring stable power generation efficiency.

[0024] In some embodiments, the piston cylinder 41 may be as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 Multiple piston cylinders 41 are fixedly installed on the top of the pressure tank 4 and evenly spaced along the circumference of the pressure tank 4. The multiple piston cylinders 41 connected to the top of the pressure tank 4 reduce the outer diameter of the piston on the piston rod 42, thus facilitating the machining and installation of the piston rod 42. Simultaneously, the multiple piston cylinders 41 increase the internal volume of the pressure tank 4, maintaining a stable pressure during water filling or emptying of the water storage tank 3.

[0025] Specifically, in this embodiment, pressure gauges for monitoring internal pressure are installed on both the water storage tank 3 and the pressurization tank 4.

[0026] Specifically, in this embodiment, a vent hole for air inlet and outlet is provided at the top of the piston cylinder 41.

[0027] In some embodiments, the aforementioned pressurization tank 4 can be adopted as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 A connecting plate 44 is slidably mounted vertically on the top of the pressure tank 4, and the piston rods 42 corresponding to the multiple piston cylinders 41 are fixedly mounted on the connecting plate 44. A guide column is fixedly mounted on the top of the pressure tank 4, and the guide column is coaxially arranged with the pressure tank 4. The middle part of the connecting plate 44 is slidably mounted on the guide column, and multiple wing plates extend outward from the connecting plate 44. The number of wing plates corresponds one-to-one with the number of piston rods 42, and the wing plates are fixedly connected to the piston rods 42. Through the setting of the connecting plate 44, the corresponding piston rods 42 inside the multiple piston cylinders 41 can move up and down synchronously, so that the pressure inside the pressure tank 4 is maintained on the combined force of the multiple piston rods 42, improving the stability during use.

[0028] Specifically, in this embodiment, the frictional force between each piston rod 42 and the inner wall of the piston cylinder 41 is inconsistent, and the weight of the corresponding gravity block 43 on each piston rod 42 is different, affecting the initial pressure when a single piston rod 42 moves upward. When the resistance to the piston rod 42 moving upward or downward is different, it causes fluctuations in the internal pressure of the pressure tank 4, affecting the stability of the internal pressure of the pressure tank 4. In this embodiment, by connecting multiple piston rods 42 together through a connecting plate 44, it is ensured that multiple piston rods 42 move up and down synchronously, stabilizing the internal pressure of the pressure tank 4.

[0029] In some embodiments, the connecting plate 44 may be adopted as follows: Figure 3 The structure shown. See also Figure 3A support rod 45 for mounting gravity blocks 43 is fixedly installed on the connecting plate 44. The gravity blocks 43 are fitted onto the support rod 45, and a limiting sleeve 431 for limiting the gravity blocks 43 from sliding out of the support rod 45 is detachably installed on the support rod 45. The support rod 45 is fixedly installed on the top of the connecting plate 44, and its length direction is vertical. The gravity blocks 43 have a ring structure and are fitted onto the outside of the support rod 45. Multiple gravity blocks 43 are fitted onto a single support rod 45. A limiting sleeve 431 is also installed on the top of the gravity blocks 43. The limiting sleeve 431 is slidably mounted on the support rod 45, and a tightening member for pressing against the support rod 45 is threaded onto the side wall of the limiting sleeve 431. The limiting sleeve 431 is fixed on the support rod 45 by the tightening member, thereby limiting the multiple gravity blocks 43 on the support rod 45.

[0030] Preferably, in this embodiment, by setting the support rod 45 and fitting multiple gravity blocks 43 on the outside of the support rod 45, the number of gravity blocks 43 on the support rod 45 can be adjusted according to design requirements, so as to achieve the effect of adjusting the pressure inside the pressurization tank 4 during the movement of the piston rod 42.

[0031] In some embodiments, the support rod 45 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 Multiple support rods 45 are fixedly installed on the connecting plate 44. The number of support rods 45 corresponds one-to-one with the number of piston rods 42, and each is coaxially arranged with its corresponding piston rod 42. The coaxial arrangement of the support rods 45 and the piston rods 42 ensures that the force exerted on the piston rod 42 by the gravity block 43 fitted outside the support rod 45 is evenly distributed, preventing tilting forces from affecting the service life of the piston on the piston rod 42. Simultaneously, it ensures that the multiple piston rods 42 can move stably up and down inside their respective piston cylinders 41.

[0032] In some embodiments, the aforementioned pressurization tank 4 can be adopted as follows: Figure 1 The structure shown. See also Figure 1 A pressure relief valve 7 is connected to the bottom of the pressure booster tank 4, and the outlet of the pressure relief valve 7 is connected to the water storage tank 5. During the process of the water pump 2 adding water to the water storage tank 3, the internal pressure of the pressure booster tank 4 increases, and the piston rod 42 inside the piston cylinder 41 moves upward. When the piston on the piston rod 42 moves to the top limit and can no longer move upward, the water pump 2 continuing to pump water will cause the internal pressure of the water storage tank 3 and the pressure booster tank 4 to continue to increase. The pressure relief valve 7 installed at the bottom of the pressure booster tank 4 can play a pressure relief protection role when the internal pressure of the pressure booster tank 4 is too high, preventing damage to the water pump 2 due to excessive pressure during the process of the water pump 2 adding water to the water storage tank 3.

[0033] Specifically, in this embodiment, a pressure relief valve 7 is added to the bottom of the pressure booster tank 4, and the outlet of the pressure relief valve 7 is connected to the water storage tank 5. This allows water located at the bottom of the pressure booster tank 4 to be discharged into the water storage tank 5. When the water pump 2 adds water to the water storage tank 3, some water flows into the pressure booster tank 4. The pressure relief valve 7 allows the water inside the pressure booster tank 4 to be discharged into the water storage tank 5.

[0034] Preferably, in this embodiment, the working state of the water pump 2 can be controlled by observing the flow state of the pressure relief valve 7. When the pressure relief valve 7 is opened, the internal pressure of the water storage tank 3 and the booster tank 4 is at the maximum critical value, thereby stopping the water pump 2 from pumping water.

[0035] In some embodiments, the water storage tank 3 described above can be as follows: Figure 1 The structure shown. See also Figure 1 A pressure boosting pipe 31 is connected to the water storage tank 3 or the pressure boosting tank 4, and a switch valve for controlling the flow state is installed on the pressure boosting pipe 31. The pressure boosting pipe 31 is connected to the top of the water storage tank 3 or the pressure boosting tank 4. Through the design of the pressure boosting pipe 31, liquid or gas can be introduced into the water storage tank 3 or the pressure boosting tank 4 in the initial state, maintaining a certain initial pressure inside the water storage tank 3 or the pressure boosting tank 4. Therefore, even when the water supply inside the water storage tank 3 is low and the piston rod 42 inside the piston cylinder 41 has moved to the lower limit position, the inside of the water storage tank 3 remains under positive pressure, ensuring that there is a certain outlet pressure at the bottom of the water storage tank 3 to drive the impeller generator 6.

[0036] In some embodiments, the water storage tank 3 described above can be as follows: Figure 1 The structure shown. See also Figure 1 A one-way valve 21 is connected to the outlet of the water pump 2 to prevent backflow of liquid. The one-way valve 21 prevents water from the storage tank 3 from flowing back into the water pump 2. Simultaneously, the pressure inside the storage tank 3 also provides some protection for the water pump 2.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
