Description

Technical Field

[0002] In recent years, various energy storage technologies have flourished. Pumped storage, compressed air storage and gravity potential energy storage are important physical energy storage technologies. Compared with battery and other energy storage technologies, they are safe, reliable, scalable, environmentally friendly, pollution-free and economical. Energy storage power stations have the functions of peak shifting, frequency and phase regulation, and emergency backup. However, the most mature pumped storage is greatly restricted by geographical conditions and is heavily dependent on terrain and topography. In addition, the geographical resources for pumped storage in my country are extremely limited, and site selection is difficult, resulting in the inability to widely use pumped storage systems.

[0003] Gravity energy storage uses a mass block as an energy storage carrier. It consumes energy to lift the mass block to a certain height, thereby converting the consumed energy into the potential energy of the mass block and storing it. When the energy needs to be released, the mass block is dropped, and the generator is driven to rotate and generate electricity during the falling process, thereby converting the potential energy into electrical energy for use.

[0004] In the prior art, the energy storage methods of gravity energy storage systems include vertical matrix energy storage, slope energy storage, etc. Gravity energy storage is not limited by the terrain environment and has a wide range of applications, but there are problems such as high construction costs. Vertical matrix gravity energy storage requires the construction of a taller building to store mass blocks. For example, the invention patent with patent number CN202210629489.3: A gravity energy storage module and a modular gravity energy storage system, is to build a taller building to store mass blocks, which is difficult to build, costly, time-consuming and labor-intensive. In order to save costs, we propose an energy storage system based on slopes and vertical mines. We plan to use abandoned mines as potential energy lifting platforms.
