Description

Fire control nozzle for energy storage battery box

Technical Field

As the number and size of energy storage power stations is now rapidly increasing, the number of energy storage battery boxes therein is much larger. The fire risk is increased due to the performance and life of the battery in the battery box, and fire accidents occur at the same time. When a fire disaster occurs, the initial fire disaster has the thermal runaway spontaneous combustion of the electric core in the battery box, then the electric core in the battery box is burnt to spread and expand all the electric cores from one electric core to the inside of the box, and finally the structure of the battery box cannot bear the pressure and the temperature in the box to burst, so that the fire disaster is rapidly spread in the whole energy storage station. In the energy storage station, a nozzle and a fire detector are usually arranged at the top of the station, and when the detector responds, the fire extinguishing medium is sprayed from the top, so that the fire spread and development in the battery box are difficult to be restrained. Meanwhile, the fire-fighting scheme is that the nozzle is arranged outside the battery box, when the fire-fighting medium is sprayed, the temperature can be reduced outside the box, the fire development in the box is slowed down, and finally the expansion of the fire cannot be prevented. Only a small part of the battery energy storage boxes of the energy storage stations are prefabricated with fire extinguishing medium nozzles, so that the early suppression effect can be achieved. However, because the prefabricated fire extinguishing medium nozzles on the battery box need to communicate in the design stage of the battery box, the fire-fighting equipment is a fire-fighting manufacturer, the production design of the battery box is relatively more numerous, and a smooth communication cooperation channel cannot be formed. The prefabricated nozzle is arranged on the battery box, so that the structure, the tightness and the like of the battery box are influenced and destroyed, the later authentication test and the like are influenced, and therefore, a plurality of battery box manufacturers have more concerns and have lower relative acceptance.

This patent is just to this kind of circumstances, designs proprietary drilling structure on the nozzle, and the installation need not destroy the outer case structure of battery box, guarantees the sealed and the demand of intensity of battery box. Meanwhile, when the fire disaster occurs in the battery box and the fire extinguishing system is required to be started, the nozzle can drill holes while cooling the box body. The corresponding problems generated when the nozzle is preassembled to the box body without fire are avoided.
