AI Technical Summary

Technical Problem

The mechanical pressure relief windows of existing prefabricated cabins are not well sealed, making them prone to water leakage and seepage, which can cause the energy storage equipment to become damp and pose a risk of short circuits. Furthermore, the opening and closing pressure values ​​are not adjustable.

Method used

Design a rainproof pressure relief valve for prefabricated cabins. It adopts a three-layer waterproof structure consisting of a flip cover, self-closing louvers, frame and magnetic block. The flip cover automatically closes under normal conditions and automatically opens to relieve pressure in case of failure. The sealing performance is enhanced by a labyrinth structure and dustproof sealing gasket.

Benefits of technology

It achieves waterproof and dustproof performance under normal conditions, and effectively relieves pressure in case of failure, preventing rainwater from entering and ensuring the safety and reliability of the energy storage equipment, meeting the IP54 protection level.

Abstract

The utility model discloses a prefabricated cabin rainproof pressure relief valve, including the installation in the cabin pressure relief mouth outside position's flap, including the installation in the cabin pressure relief mouth inside position's self -inclined louver, still have the frame between the flap and the pressure relief mouth, and the frame is fixed to the pressure relief mouth side side, and the flap upside position has the pin shaft, is used for with the frame corresponding upside position flip type hinged installation, the downside position of frame is provided with the magnetic attraction piece, is used for the magnetic attraction type fixed flap downside. The cabin internal pressure normal state, the flap automatic drooping, and the magnetic attraction closes, when the battery in the cabin appears the fault, produces VOC, CO gas time, in order to prevent the explosion, and the pressure rise effect pushes open the flap, and the flap turns over, and the downside appears the pressure relief side, and the pressure relief is completed after the pressure balance, and the flap automatic landing forms the seal, prevents dust and rainwater etc. from entering the cabin inside.
