Gravity energy storage system based on efficient lifting and transferring of multiple heavy objects

Abstract

The invention discloses a gravity energy storage system based on efficient lifting and transferring of multiple heavy objects. The gravity energy storage system comprises a vertical shaft (1), a roadway (2), an upper heavy object storage warehouse (3), a lower heavy object storage warehouse (4), a supporting beam frame (5), an electric lifting machine (6), a lift car (7), an AGV forklift (8) and n heavy object carrier modules (9). Under the energy storage working condition, n weight carrier modules (9) are sequentially transferred into the lift car (7) from the weight storage lower warehouse (4) through the AGV forklift (8), then lifted to the upper portion of the vertical shaft (1) through the electric hoister (6) and transferred to the weight storage upper warehouse (3) to be stored through the AGV forklift (8); and under the energy release working condition, n weight carrier modules (9) are sequentially transferred into the lift car (7) from the weight storage upper warehouse (3) through the AGV forklift (8), the weight carrier modules (9) drive the electric hoister (6) to generate electricity in the falling process, and after the weight carrier modules (9) fall to the bottom, the weight carrier modules (9) are transferred into the weight storage lower warehouse (4) from the lift car (7) to be stored through the AGV forklift (8).

Description

technical field [0001] The invention relates to the technical field of energy storage, in particular to a gravity energy storage system based on the efficient lifting and transfer of multiple objects. Background technique [0002] Carbon peak carbon neutrality "30.60" goal is a solemn commitment made by China to deal with global climate change, and it is also a hard constraint when China formulates policies, which has a profound impact on the economy and the market. To achieve carbon peaking and carbon neutrality, on the one hand, we must gradually reduce the consumption of fossil energy, and on the other hand, we must effectively increase the proportion of renewable energy consumption. my country's new energy sources such as wind energy and solar energy are mainly distributed in the northwest region, and solar power generation is concentrated in the daytime, while the power load is mainly distributed in the southeast coastal area, and the ratio of power consumption at night...

Problems solved by technology

In order to solve the shortage of gravity energy storage for a single heavy object in a shaft, Chinese invention patent 202110714699.8 proposes a method for transferring multiple heavy objects using a self-driving rail car. If there are too many heavy objects, multiple self-driving rail cars need to The independent power supply and control system reduces the overall reliability of the system and increases the cost of manufacturing and operation and maintenance; Chinese invention patent 202111173003.1 proposes a method of transferring multiple objects using multiple beams and radial beams on the gantry. The problem of longer time for horizontal transfer of objects and higher manufacturing cost of the beam frame
