It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1:
as shown in fig. 1, the circulating hydraulic power generation device comprises a water storage tank 1, a hydraulic power generator 2 and a water storage tank 3 from top to bottom in sequence; the water storage tank 1 comprises an upper tank body 11 and a lower tank body 12, and the caliber of the lower tank body 12 is sequentially reduced from top to bottom; one end of the first communicating pipe 14 is communicated with the bottom of the lower tank body 12, and the other end is communicated with the water inlet end of the hydroelectric generator 2; a valve 13 is arranged on the first communicating pipe 14; one end of the second communicating pipe 31 is communicated with the water outlet end of the hydroelectric generator 2, and the other end is communicated with the top of the water storage tank 3; a water pump 5 is arranged in the water storage tank 3, one end of a fourth communicating pipe 51 is communicated with the water outlet end of the water pump 5, and the other end is communicated with the upper part of the upper tank body 11; the output end of the hydroelectric generator 2 is respectively electrically connected with an electric load 4 and a water pump 5.
Lifting water into a high-level water storage tank 1 through lifting equipment, lifting and storing; when the device needs to be used for generating electricity, the valve 13 is opened, water at the bottom in the water storage tank 1 enters the hydroelectric generator 2 through the first communicating pipe 14 and flows into the water storage tank 3 from the second communicating pipe 31 to drive the blades of the hydroelectric generator 2 to rotate, so that the hydroelectric generator 2 works to generate electric energy, and the potential energy part of the water in the water storage tank 1 is converted into the electric energy; then, a part of electric energy generated by the hydroelectric generator 2 is used as a power source of the water pump 5, so that the water pump 5 works, and part of water in the water storage tank 3 is lifted into the water storage tank 1 through the third communicating pipe 32; so as to ensure that a certain amount of water can be stored in the water storage tank 1 and the hydroelectric generator 2 can work continuously; then part of the electric energy generated by the hydroelectric generator 2 is transmitted to an electric load 4 for domestic or industrial electricity utilization; can realize converting into the electric energy with a part of the water potential energy that stores up in advance through this device to partly of the electric energy that will produce is used for again rising the water of low level to the high level, carries out circulation electricity generation, water storage, promotes the duration of this device electricity generation.
The principle is as follows: because the volume of the water storage tank 1 is large, a small amount of water in the lower tank 12 can generate large pressure under the heavy pressure of water in the upper tank 11, relatively speaking, the caliber of the water outlet end of the inverted cone-shaped lower tank 12 is gradually reduced, and the flow rate of water flow in the first communication pipe 14 is also improved, the electric energy (E1) generated by 1 cubic centimeter of water at the bottom of the water storage tank 1 (the 1 cubic centimeter of water is high pressure generated by the large amount of water at the upper layer) is more than the electric energy (E2) generated by the single 1 cubic centimeter of water (the standard atmospheric pressure is above the 1 cubic centimeter of water); when the water of 1 cubic centimeter in the water storage tank 3 is lifted to the upper part of the water storage tank 1, the potential energy (E3) is only needed to be overcome, therefore, when the device continuously works, the electric energy generated by the hydroelectric generator 2 is larger than the electric energy consumed by the water pump 5, so that when part of low-level water in the water storage tank 3 is lifted to the water storage tank 1, the device can simultaneously output part of the electric energy to the electric load 4 and continuously ensure the running for a certain time (according to the water storage capacity in the water storage tank 1 and the power consumption condition of the electric load 4). (wherein: E1 > E3 is greater than E2)
In practice, the applicant manufactures a water storage tank 1 (full of water) with the height of 3 meters and the diameter of 1 meter, the bottom of the water storage tank 1 is 1.5 meters away from the ground, an asynchronous hydraulic generator is selected as the hydraulic generator 2, a small three-phase asynchronous motor (no-load) is selected as the electric load 4, and a small water pump is selected as the water pump 5, when the device works, the output voltage of the hydraulic generator 2 can reach 380V, the output current reaches 2.2A, the no-load running current of the electric load 4 is about 1A, and the operation current of the water pump 5 is about 1A, and the device can keep running for a period of 1-5 days continuously.
Preferably, the larger the capacity of the water storage tank 1, the longer the continuous operation cycle of the apparatus.
Preferably, the higher the height of the water storage tank 1, the longer the continuous operation cycle of the device.
Considering the energy conversion efficiency and the loss of the generator and the corresponding load, the water yield in the water storage tank 1 is larger than the water inflow of the water storage tank 1 in unit time, so that the device has certain continuous operation time, and when the water in the water storage tank 4 reaches a certain amount, the water in the water storage tank 4 needs to be lifted to the water storage tank 1 again by using other power supplies.
Example 2:
as shown in fig. 1, the present embodiment optimizes the communicating tube structure for the above embodiment.
The caliber of the first communicating pipe 14 in the circulating hydraulic power generation device is smaller than that of the second communicating pipe 31. When the aperture of the first communicating pipe 14 is smaller than the aperture of the second communicating pipe 31, the flow velocity of water in the first communicating pipe 14 can be increased, and the power generation amount of the hydroelectric generator 2 can be increased.
Preferably, the aperture of the fourth communication pipe 51 is smaller than the aperture of the first communication pipe 14, so that the water in the water storage tank 3 is lifted to the water storage tank 1 with the minimum energy consumption, and the energy consumption caused by water circulation is reduced.
