AI Technical Summary

Technical Problem

The poor watertightness and airtightness of energy storage containers affect the operational reliability and stability of energy storage containers and energy storage systems.

Method used

An inner sealing strip and an outer sealing strip are installed on the enclosure. When the door panel closes the opening, it forms an interference fit with the inner sealing strip. When the door panel closes the opening, the outer sealing strip, together with the enclosure and the door panel, is constrained within the gap space. Combined with the use of fire-fighting circulation pipelines and flame-retardant media, the sealing performance and fire and explosion protection capabilities are improved.

Benefits of technology

The watertightness and airtightness of the energy storage container have been improved, reducing the probability of ambient water vapor and air entering the container, enhancing the operational reliability and stability of the energy storage container and system, and reducing the risk of combustion and explosion in the event of thermal runaway.

Abstract

The invention relates to an energy storage container and an energy storage system. The energy storage container comprises a container body with an opening in one side; the door plate is rotationally connected to the box body and used for opening or closing the opening, and a gap space is formed between the door plate and the box body; the sealing assembly comprises an inner sealing strip and an outer sealing strip, the inner sealing strip is connected to the box body and surrounds the opening, and the outer sealing strip is connected to the door plate; the door plate is in interference fit with the inner sealing strip when the opening is closed, and the outer sealing strip is in interference fit with the box body when the opening is closed by the door plate so as to seal the clearance space. According to the energy storage container, the inner sealing strip and the outer sealing strip seal the inner side and the outer side of the door plate correspondingly when the opening of the door plate is closed, the sealing performance between the door plate and the container body is effectively improved, the probability that environmental water vapor and air enter the container body is reduced, and the overall water tightness and air tightness of the energy storage container are improved; and the operation reliability and stability of the energy storage container and the corresponding energy storage system are improved.
