Description

Technical Field

[0001] The utility model specifically relates to a pump group type fire suppression device for electrochemical energy storage fire safety. Background Art

[0002] Lithium batteries have a high energy density and can store a large amount of electrical energy in a relatively small volume and weight. They also have a fast charge and discharge rate, can quickly respond to changes in energy demand, and provide stable power output. They are widely used in energy storage systems. Lithium battery energy storage systems are generally equipped with portable fire extinguishers to prevent abnormal chemical reactions or short circuits that may occur during charging or discharging, which may lead to thermal runaway fires, thereby improving the safety of energy storage.

[0003] The existing manual fire extinguishing method using portable fire extinguishers is slow in efficiency. In addition, the fire caused by lithium batteries burns quickly, releases thick smoke and toxic gases, which greatly endangers the safety of workers. It is not convenient to remotely control the spraying of fire extinguishing agents to extinguish the fire. In order to quickly respond to the fire, cover the fire and improve the fire extinguishing efficiency, we propose a pump-type fire suppression device for electrochemical energy storage fire safety.
