Battery box supporting roller and energy storage device using the supporting roller

Abstract

The invention relates to a battery box supporting roller and an energy storage device using the supporting roller. The supporting roller of the battery box includes a rotating shaft and a rolling support body. The rolling support body is used to provide rolling support for the bottom surface of the battery box. The outer peripheral surface of the rolling support body is provided with annular grooves. There are more than two annular grooves. Each annular groove The grooved rolling supports are arranged at intervals in the axial direction. The annular groove divides the rolling support body into multiple support areas in the axial direction. When a support area is not flat enough for the battery box or the installation level of the rollers is poor, it can be more easily deformed to fit the surface of the battery box, and The deformation of the support area will not affect the support of the other support areas to the battery box, and the groove can also accommodate some protrusions on the battery box, ensuring the support area of ​​the battery box support rollers on the battery box, which can better prevent the battery from The box is worn due to uneven force, and it can better prevent problems such as partial wear and damage of the supporting rollers.

Description

technical field [0001] The invention relates to a battery box supporting roller and an energy storage device using the supporting roller. Background technique [0002] As an important way of electric energy storage, battery energy storage has the advantages of flexible configuration of power and energy and fast response speed, and plays an important role in cooperating with centralized or distributed new energy grid connection and grid operation assistance. [0003] Batteries and auxiliary equipment for storing electric energy are often carried by mobile energy storage containers to form an energy storage device that can be transported to places where electric energy is needed. The energy storage device generally includes a battery rack and a battery box. The battery rack has a battery box installation cavity for the battery box to be loaded and unloaded in a horizontal push-pull manner. In order to facilitate the loading of the battery box, reduce resistance, and reduce we...
