The outlet flange is a main mounting surface, and the strength membrane, the two layers of gaskets and the weather protection cover can be fixedly connected through bolts, so that the whole plate body is fixed, and meanwhile, the opening channel of the strength membrane is limited, and the strength membrane is not prone to being exploded. The four sides of the weather protection cover are connected to the outlet flange at one side, so that the opening direction is limited while the opening is not influenced. The weather protection cover is mainly used for reducing and restraining the influence of weather on the plate body, and heat preservation and weather resistance are improved through heat preservation cotton. Meanwhile, the first limiting rings forming the isoelectric point between two limiting rings and the second limiting rings forming the isoelectric point between two limiting rings can prevent the damage of a metal structure, the damage of equipment and the like caused by potential difference between a metal object and a protection conductor of each electrical system due to the fact that the energy storage equipment is protected.

Further, the heat preservation cotton is fixedly arranged in the weather protection cover and the outlet flange in a full-sticking mode, so that the board body can be prevented from being scraped easily under the condition of high air volume level.

Further, be equipped with the installing frame that is hollow cube form that is used for the mounting panel body on the energy storage equipment, be equipped with the cross strengthening rib in the installing frame, the plate body is installed on this cross strengthening rib, can support the intensity membrane and can not take place to warp under the weight of rock wool through the design of cross strengthening rib, also makes the plate body whole have certain anti negative pressure ability simultaneously, avoids taking place to sink.

Further, the top surface of the weather shield is inclined to one side, so that the weather shield can play a role in draining accumulated water.

Compared with the prior art, the scheme has the remarkable advantages that:

1. the design of the weather protection cover is adopted to limit the opening direction, reduce the influence of weather on the plate body, prolong the whole service life and simultaneously not greatly influence the explosion venting pressure;
