Problems solved by technology

As for the mountain energy storage power station, the publication number is CN103448734B, which discloses the energy storage method of using cableway to lift heavy objects, but its cableway system uses the cable car fixedly connected to the cableway. When in use, it is necessary to fill the cable car with heavy objects such as sand and gravel for lifting energy storage or falling energy release. The cable car runs in a unidirectional cycle on the upper and lower cableways, and the two cableways need to be equipped with corresponding load-bearing towers and load-bearing pulleys. and other facilities and equipment, not only the construction cost is relatively high, but also because the upper and lower cableways are arranged side by side and in order to prevent the opposite collision of the upper and lower cable cars, the cableway system occupies a relatively large width of the near-ground space, and the layout is not compact, which is not easy Adapt to complex mountainous terrain with many ravines and narrow
In addition, the cable car filled with gravel tends to accumulate rainwater in rainy days, resulting in an increase in the ineffective lifting weight outside the energy storage system, which reduces the energy efficiency of the system

Embodiment 1

[0024] like figure 1 and 2 As shown, the mountain multi-cableway multi-cycle load-sharing gravity energy storage power station system of the present embodiment includes a hoisting device (the hoisting machine 13 in this embodiment), a power generating device (the generator 12 in the present embodiment), two rotating wheels 1 and the traction cableway 4 that circulates between the two rotating wheels 1. On one of the two rotating wheels 1, the hoisting machine 13 and the generator 12 are connected in transmission through a shiftable transmission box 14, and the hoisting machine 13 and the generator 12 can only be driven by shifting the transmission box 14. One is selected to be connected with the rotating wheel 1; in other words, the rotating wheel 1 is selectively connected with the hoisting device or the generating device. One rotating wheel 1 is set at a low altitude position, generally speaking, it is at the foot of the mountain body 9, and the other rotating wheel 1 is s...

Embodiment 2

[0035] like image 3 and 4 As shown, this embodiment is substantially the same as the previous embodiment, the difference being:

[0036] In this embodiment, the hoisting device and the power generation device are integrated into a winch and power generation integrated machine 20, which has the functions of hoisting and power generation. It only needs to be switched, in other words, the rotating wheel 1 is still selectively connected with the hoisting device or the generating device.

[0037] In this embodiment, support wheels 8 are provided on opposite sides of the energy storage body 5 (that is, two sides corresponding to each other at approximately 180°), and each support wheel 8 is connected with a fixed cableway 6 below. The energy storage body 5 with this structure is positioned at three points, so that the running posture of the energy storage body 5 is more stable during operation, its load-bearing system is also more complete, and the system security is higher.

Embodiment 3

[0040] This embodiment is substantially the same as the previous embodiment, except that:

[0041] like Figure 5 As shown, the carrier frame 10 of this embodiment is a gantry structure, including a beam 18 and columns 19 fixedly connected to both ends of the beam 18 . The cable 3 on the loading side is movably connected to the inner side of the beam 18 through the supporting pulley 17, and the inner side of the two columns 19 is fixedly connected with the fixed cableway 6 through the fixing device 11 (specifically a connecting block here). Compared with the traditional T-shaped bearing tower with cantilever, the gantry-type bearing frame 10 avoids the cantilever bearing structure, the load-bearing structure is more reasonable, and the safety is higher. In addition, it also makes full use of the columns 16 on both sides. To carry and connect the fixed cableway 6, the laying cost of the fixed cableway 6 is greatly reduced.

[0042] In addition if Image 6 As shown, on the tw...

Abstract

The invention provides a mountain multi-cableway multi-cycle partial load type gravity energy storage power station system which comprises a winding device, a power generation device, two rotating wheels and a traction cableway cyclically operating between the two rotating wheels, the rotating wheels are selectively connected with the winding device or the power generation device, one rotating wheel is arranged at a low-altitude position, and the other rotating wheel is arranged at a low-altitude position. One rotating wheel is arranged at a high altitude position, the other rotating wheel is arranged at a high altitude position, the traction cableway comprises a mounting side cable and a no-load side cable, a plurality of energy storage bodies are detachably connected to the mounting side cable through a mounting device, and a plurality of bearing frames fixed to the ground are movably connected to the mounting side cable. And the occupied width of the near-earth space is small, the structure is compact, more parallel cableways can be arranged under the favorable terrain to improve the total installed capacity of the whole energy storage power station, and the construction cost increase caused by terrain interference is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of electric energy storage, and in particular relates to a multi-cable multi-cycle multi-cycle load-sharing gravity energy storage power station system in mountainous areas. 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 power energy storage technology has been developed. Existing electric energy storage technologies are divided into pumped hydropower stations, battery power stations and mountain energy storage stations. As for the mountain energy storage power station, the publication number is CN103448734B, which discloses the energy storage method of using the cableway to lift heavy objects, but its cableway system uses a cable car fixedly connected to the cableway. When in use, it is necessary ...
