Description

TECHNICAL FIELD

[0001] The utility model relates to the field of fire fighting, especially a controllable non-pressure storage cabinet type fire extinguishing device. BACKGROUND

[0002] The energy storage industry in China is growing rapidly, and the installed capacity of electrochemical energy storage power stations is increasing. However, the lithium-ion batteries used in electrochemical energy storage power stations are essentially chemical components containing high-energy substances, and there is a risk of fire during use. The fire development process is fast, and its characteristics are different from traditional building fires or other types of fires. Once it catches fire, it is difficult to extinguish, and after the fire is extinguished, it is easy to reignite, so the fire extinguishing device needs to release the fire extinguishing agent multiple times to continuously suppress the fire according to the characteristics of lithium-ion battery fire reignition. However, most current cabinet or other fire extinguishing devices are designed mainly for general building fire scenes, and are generally pressure storage type designs without the function of precise multiple spraying of fire extinguishing agent, making it difficult to meet the requirements of electrochemical energy storage systems for fire extinguishing devices. In addition, pressure storage devices need periodic maintenance, and the entire set needs to be replaced after the release of the fire extinguishing agent. Many electrochemical energy storage power stations are located in remote areas without human attendance, and it is not convenient to maintain the pressure storage type fire extinguishing device for a long time. Some other fire extinguishing devices also have a float type liquid level sensor inside to monitor the amount of fire extinguishing agent in the tank, but this sensor is installed in the tank, with a complex structure and high maintenance cost. In particular, due to its structural principle and the influence of fire extinguishing agent pressure, density, and viscosity, its measurement accuracy is low, and it can only be used to monitor the fault state of fire extinguishing agent depletion, but cannot accurately measure and timely feedback the amount of fire extinguishing agent, and cannot be used for applications that require real-time feedback to automatically control the start time and accurately control the amount of fire extinguishing agent sprayed.

[0003] The utility model aims at overcoming the deficiency of traditional fire extinguishing cabinet type fire extinguishing device in application of electrochemical energy storage power station performance, and designs a controllable non-pressure storage cabinet type fire extinguishing device. The fire extinguishing agent is installed in the non-pressure storage fire extinguishing agent tank. When it needs to be used, the pump set is started according to the set program or feedback information to inject the fire extinguishing agent multiple times into the fire extinguishing agent output pipeline to release the fire extinguishing agent.
