Problems solved by technology

[0005] 1. The carrying capacity of the aerial ropeway is low
Aerial ropeways rely on steel wire ropes to support and pull trucks, and rely on supports and supporting wheels to support steel wire ropes. Generally, the distance between supports is large, and the carrying capacity of a single truck is lower than that of rail-type trucks. Therefore, the energy storage and power generation capacity of the cableway based on it is relatively small. , not suitable for building into a large energy storage power station
[0006] 2. The automatic loading and unloading devices at both ends of the cableway are complex, costly, difficult to load and unload, time-consuming, power-consuming, and inefficient
If the automatic loading and unloading devices at both ends of the cableway can be successfully operated, the position of one end is relatively fixed, and the other end will adjust the storage position and storage height according to the amount of goods stored, and the frequency of storing goods will also change at any time. The device requires complex and intelligent devices and operating equipment, and its construction and

Abstract

The invention discloses a sand lifting and energy storing power station, and aims to change intermittent input electric energy into electric energy which can be stably output and is convenient to use by increasing and lowering the height of quicksand. A bridge (2) is built above a high-position sand warehouse (1), and a tunnel (4) is built under the high-position sand warehouse (1). A bridge (8) is built above a low-position sand warehouse (7), and a tunnel (9) is built under the low-position sand warehouse (7). Sand leakage openings (5) are respectively formed in the bottom of the high-position sand warehouse (1) and the bottom of the low-position sand warehouse (7). The sand warehouses at the upper portion and the tunnels at the lower portion are communicated. Quicksand control devices (6) are installed at the portions of the sand leakage openings (5). A sand conveying channel (11) is built between the high-position sand warehouse (1) and the low-position sand warehouse (7). A rail (10) is built in the direction of the bridge (8), the sand conveying channel (11) and the tunnel (4). A ground cable car sand lifting device (12) is installed on a rail (3). A ground cable car electricity generating device (13) is installed on the rail (10).

Description

technical field [0001] The invention belongs to the field of energy storage technology, and in particular relates to a power station technology and device for energy storage and power generation by using a ground cable car device to lift and lower quicksand. Background technique [0002] Due to the intermittency of solar energy and wind energy, the electricity generated by solar energy and wind energy also has intermittent problems, and the energy needed by human beings requires a stable and continuous supply, so the discontinuous electricity generated by solar energy and wind energy is stored and It is very necessary to convert it into continuous and stable electric energy when needed. [0003] Among the existing large-scale energy storage power generation technologies, pumped storage power generation technology has been widely used. However, in Northwest my country, which is rich in solar and wind energy resources, due to the shortage of water resources, the construction ...
