Detailed Description
As shown in fig. 1-4, a siphon water delivery structure of a synergistic pumped storage power station comprises an upper reservoir; one side of the upper reservoir is provided with an upper reservoir water inlet and outlet pipeline, and the bottom of the upper reservoir is provided with a siphon ascending section which is communicated with the upper reservoir water inlet and outlet pipeline to form a siphon pipeline; the rising section of the siphon pipe is inclined towards the bottom of the upper reservoir and forms an included angle with the water inlet and outlet pipeline of the upper reservoir.
Preferably, an arc-shaped switch valve is arranged at the joint of the siphon ascending section and the water inlet and outlet pipeline of the upper reservoir.
Preferably, the arc-shaped switch valve is of an arc-shaped plate structure; the arc switch valve is an electric control valve.
Further, the upper reservoir of the pumped-storage battery comprises a normal water storage level and a dead water level.
Further, the vertical height of the upper section of the siphon cannot be 10m higher than the height of the water column supported by the atmospheric pressure.
Preferably, the siphon ascending section is connected with the opening of the side surface of the upper reservoir water inlet and outlet pipe, but not with the water inlet of the upper reservoir water inlet and outlet pipe itself.
The working principle of the utility model is as follows:
when the water storage device is used, the arc switch valve is firstly opened to the state of fig. 2, at the moment, the siphon ascending section 4 and the upper reservoir water inlet and outlet pipeline 6 are simultaneously in the opened state, at the moment, water is pumped from the lower reservoir to the upper reservoir, when the water level of the upper reservoir is pumped to 2 normal water storage levels, the arc switch valve 5 is closed, the arc switch valve 5 is in the state of fig. 3, and the siphon ascending section 4 and the upper reservoir water inlet and outlet pipeline 6 are simultaneously in the closed state, so that water is stored in the upper reservoir.
When the water above the dead water level of the upper reservoir is used for generating electricity, the arc-shaped switch valve is restarted to the state of fig. 2, the siphon ascending section 4 and the upper reservoir water inlet and outlet pipeline 6 are simultaneously in the open state, at the moment, the water flows in through the water inlets of the siphon ascending section 4 and the upper reservoir water inlet and outlet pipeline 6, flows out from the water inlet of the upper reservoir water inlet and outlet pipeline 6, and the water flows from the upper reservoir to the lower reservoir for generating electricity.
When the water level of the upper reservoir drops to the dead water level 3, the arc-shaped switch valve 5 is opened to be in a state of fig. 4, the siphon ascending section 4 is in an opened state, the upper reservoir water inlet and outlet pipeline 6 is in a closed state, at the moment, the siphon ascending section 4 is communicated with the upper reservoir water inlet and outlet pipeline 6 to form a siphon pipeline, and the dead water level is higher than the highest position of the siphon ascending section 4, so that the whole siphon pipeline is filled with water at the moment, the water outlet requirement of the siphon pipeline is met, the water under the dead reservoir can flow to the upper reservoir water inlet and outlet pipeline 6 through the water inlet of the siphon ascending section 4, flows out from the water outlet of the upper reservoir water inlet and outlet pipeline 6, and flows to the lower reservoir to generate electricity. When the water level is lowered to the lowest point of the siphon ascending section 4, the water discharging and generating process of the pumped storage power station is completed. When water is required to be pumped from the lower reservoir to the upper reservoir again, the arc-shaped switch valve is opened to the state shown in fig. 2, and the process is repeated.
