detailed description

The wind power pumped storage power generation device is composed of a wind power generation device 1, a water pump 2, a U-shaped reservoir 3, a hydroelectric generator 4, a controller 5, a piston 6, a weight 7, a water pipe 8, a water inlet 31, and a water outlet 32. A first-level one-way valve 33, a second-level one-way valve 34, a first-level inductor 35, a second-level inductor 36, a water inlet column 37, and a water storage column 38. It is characterized in that the wind power generation device 1 is connected to the water pump 2; the water pump 2 is arranged on the water pipe 8; one end of the water pipe 8 is connected to the water inlet 31 of the U-shaped reservoir 3, and the other end is placed in the water; Machine 4 links to each other with U-shaped reservoir 3 water outlet 32; Described water inlet 31 is provided with first-level one-way valve 33, and described water outlet 32 is provided with secondary one-way valve 34; Described U-shaped reservoir 3 is composed of a water inlet column 37 and a water storage column 38; the piston 6 is arranged in the water storage column 38 of the U-shaped reservoir 3, and the weight 7 is located above the piston 6; the upper end of the water storage column 38 is provided with a primary sensor 35, and the water storage column The lower end of 38 is provided with secondary inductor 36.

The water inlet 31 of the U-shaped reservoir 3 is provided with a first-level check valve 33, and the water extracted by the water pump 2 enters the U-shaped reservoir 3 through the first-level check valve 33; the water outlet 32 of the U-shaped reservoir 3 There is a secondary one-way valve 34 inside, the opening and closing of the secondary one-way valve 34 is controlled by the controller 5, and the water in the reservoir can flow out from the water outlet 32 through the secondary one-way valve 34.

The upper end of the side wall of the U-shaped reservoir 3 water storage column 38 is provided with a primary sensor 35; the lower end of the side wall of the U-shaped reservoir 3 water storage column 38 is provided with a secondary sensor 36; the primary sensor 35 and the secondary sensor 36 Pass the signal to the controller 5.

The start and stop of the water pump 2 and the hydroelectric generator 4 are controlled by the controller 5;

The water inlet column 37 and the water storage column 38 of the U-shaped reservoir 3 are cylindrical, the radius of the water inlet column 37 of the U-shaped reservoir 3 is smaller than the radius of the water storage column 38 , and the water inlet column 37 is higher than the water storage column 38 .

There are two working states of the utility model: the state of pumping energy storage and the state of releasing water to generate electricity.

As shown in Figure 1 and Figure 2, when the wind-driven pumped-storage power generation device is in the state of pumped-storage energy, the electric energy required for the operation of the pump 2 is provided by the wind power generation device 1, and the water pumped out by the pump 2 passes through the pumping water in the direction of the arrow. Water pipe 8, water pump 2, water inlet 31, one-level check valve 33 enter in the U-shaped reservoir 3. During the water pumping process, the primary one-way valve 33 is automatically opened due to the force of the water flow, and the controller 5 controls the secondary one-way valve 34 to close, and the hydraulic generator 4 is in a standby state at this time. As the water in the U-shaped reservoir 3 gradually increases, the piston 6 and the weight 7 on it are lifted up due to the continuous increase of water pressure. When the piston 6 reaches the height of the first-level sensor 35, the first-level The sensor 35 sends a signal to the controller 5, and the controller 5 controls the water pump 2 to stop pumping water, and then the device switches to the state of releasing water and generating electricity.

As shown in Figures 1 and 2, when the wind pumped storage power generation device is in the state of discharging water to generate electricity, the controller 5 opens the secondary check valve 34, and the primary check valve 33 is naturally closed due to water pressure. Due to gravity, the weight 7 pushes the piston 6 to move downward, and the water in the U-shaped reservoir 3 passes through the secondary one-way valve 34 and the hydroelectric generator 4 sequentially along the direction of the arrow, and is finally discharged from the water outlet 32. The generator 4 is in the state of generating electricity. Along with the water in the U-shaped reservoir 3 gradually decreases, the weight 7 on the piston 6 and its top will fall due to the continuous reduction of water pressure. When the piston 6 descends to the height of the secondary sensor 36, the secondary sensor 36 sends a signal to the controller 5, and the controller 5 closes the secondary check valve 34 to control the water pump 2 to start pumping water, and then the device is converted into a pumping storage system. able state.

When the wind pumped storage power generation device performs pumped storage, since the density of the weight 7 in the water storage column 38 is greater than the density of water, the energy required to pump a certain amount of water is greater than that without the weight 7. Correspondingly, When the amount of water in the water storage column 38 was constant, the energy stored in the water storage column 38 was larger than when there was no weight 7 . Therefore, in the case of the same volume, the wind pumped storage power generation device provided by the utility model can store more energy, which is equivalent to saving the volume.
