Embodiment Construction
[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0037] Such as figure 1 As shown, it is a pumped energy storage power station built by using an abandoned mine disclosed by the present invention, including a lower reservoir 1 and an upper reservoir 2, the lower reservoir 1 is an abandoned mine pit, the lower reservoir 1 and the upper reservoir 2 are connected by a water diversion pipeline 3, and The diversion pipeline 3 connects the electromechanical chamber 4 and the surge chamber 5, and the height of the surge chamber 5 is higher than the electromechanical chamber 4, and the upper reservoir 2 is formed by excavating on the ground plane outside the pit where the lower reservoir 1 is located. Potholes.
[0038]Because the upper reservoir 2 is arranged on the plane of the ground, it is more stable than setting the upper reservoir 2 on the side slope of the pit where the lower reservoir 1 is located. A circ...

The invention relates to a water pumping energy storing power station built by utilizing an abandoned pit. The water pumping energy storing power station comprises a lower storage reservoir and an upper storage reservoir; the lower storage reservoir is the abandoned pit and is connected with the upper storage reservoir through a water diversion pipeline; the water diversion pipeline is connected with an electromechanical chamber and a surge chamber; the surge chamber is higher than the electromechanical chamber; the upper storage reservoir is arranged outside the pit of the lower storage reservoir; and the upper storage reservoir is a hollow hole formed through excavation on the ground plane. The upper storage reservoir is arranged on the ground plane, and compared with the background technology that the upper storage reservoir is arranged on the side slope of the pit of the lower storage reservoir, the position of the upper storage reservoir in the scheme can realize a more stable effect.
Description
technical field [0001] The invention relates to the technical field of pumped-water storage power stations, in particular to a pumped-water storage power station built using abandoned mine pits. Background technique [0002] The time difference of the current electricity load has caused a huge time difference in electricity consumption. In order to avoid energy waste, different methods are used to adjust the peak load of the power grid to maintain the balance of the power grid, such as compressed gas energy storage, pumped water storage, thermal power adjustment, etc. [0003] At present, the Chinese patent document with the application publication number CN108643140A discloses a system and method for pumping energy storage using an abandoned open pit mine. The system includes an upper reservoir, a lower reservoir, a dam, an electromechanical chamber, etc.; the method includes: The reservoir stores water for use; when wind power or solar power or power stations exceed demand...
