Photovoltaic charging pile safety equipment

Abstract

The invention belongs to the technical field of photovoltaic charging piles, and particularly relates to photovoltaic charging pile safety equipment. The device comprises a photovoltaic panel, a charging console and a storage battery. When the storage battery explodes, the impact on the two sealing protrusions can be increased, and the slidable sealing protrusion moves upwards to be flush with the other sealing protrusion to seal the inner hole of the heat dissipation pipe. Therefore, the explosive shock waves can only flow out along the shock wave release channel, when the shock waves flow to the outlet of the shock wave release channel, the shock waves impact the impact swing plate installed at the outlet of the shock wave release channel, the exhaust cover is opened through the impact swing plate, and the square opening in the installation plate is completely opened. Thus, the shock waves of explosion are discharged from the square opening of the installation plate along the shock wave release channel, the situation that explosion is further expanded due to the fact that the shock waves of the explosion cannot be discharged in time is prevented, and other internal equipment cannot be damaged.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic electric piles, and in particular relates to safety equipment for photovoltaic charging piles. Background technique [0002] With the development of new energy vehicles, electric vehicles or hybrid vehicles with motor drive are more and more accepted by consumers. The function of the charging pile is similar to the fuel dispenser in the gas station. It can be fixed on the ground or wall, installed in the parking lot of public buildings and residential areas or in the charging pile, and can charge various types of electric vehicles according to different voltage levels. At present, the power source of photovoltaic charging piles on the market is built on the roof of the charging station or the roof photovoltaic power station of the surrounding buildings. Photovoltaic charging piles can be used in relatively remote places without the need for additional power grids. [0003] Generally, photovo...

AI Technical Summary

Problems solved by technology

[0003] Generally, photovoltaic charging piles are arranged in places with sufficient light sources, and the temperature is relatively high at noon, which requires strong heat dissipation capabilities. However, due to the use of batteries, there are problems such as flammability and explosion in the use of batteries.

[0004] At present, the method of solving battery safety measures often adopts better heat dissipation device and explosion-proof equipment. The two sets of equipment are operated independently, and the equipment cost is relatively high; and the heat dissipation device uses a cooling fan to actively dissipate heat in order to meet the heat dissipation requirements; generally installed photovoltaic The electricity generated by the panels is not enough to meet the needs of electric vehicles, and active cooling will increase the consumption of electricity generated by photovoltaics

However, in the current explosion-proof equipment, the shock wave is suppressed after the explosion, and the internal equipment is basically damaged.
