Comprehensive fire extinguishing device for container type lithium ion battery energy storage system

Abstract

The invention discloses a comprehensive fire extinguishing device for a container type lithium ion battery energy storage system. The comprehensive fire extinguishing device comprises a base, whereina box body is fixedly connected to the upper end of the base, a plurality of lithium ion batteries are arranged at the inner bottom of the box body, a plurality of battery protective covers are arranged at the inner bottom of the box body, the battery protective cover are arranged on the outer walls of the lithium ion batteries in a sleeving mode, a water storage cavity is formed in the box body,a square groove is formed in the base, a plurality of through holes communicating with the interior of the square groove are formed in the inner bottom of the box body, a channel communicating with the square groove is formed in the base, the channel communicates with the interior of the water storage cavity, and a first water pump is arranged on the inner wall of the square groove. According to the comprehensive fire extinguishing device for the container type lithium ion battery energy storage system, the temperature in the box body is detected through a temperature sensor, when the temperature in the box body rises to the dangerous temperature, a second water pump is started through a first PLC module, water in the water storage cavity is pumped into a water outlet pipe and is sprayed out by spray holes in a spray head, and then the fire extinguishing treatment in the box body can be realized.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a comprehensive fire-fighting device for a container-type lithium-ion battery energy storage system. Background technique [0002] In recent years, with the development of smart grid construction, the demand for battery energy storage has been increasing. The battery energy storage system has the advantages of peak shaving and valley filling, emergency backup, and improvement of power quality. Lithium-ion batteries have gradually become the most widely used batteries in battery energy storage systems due to their many advantages such as high energy density, high output power, long charge and discharge life, wide operating temperature range, and small self-discharge. At the same time, with the increasing demand for battery energy storage applications, fast construction and mobility have become new requirements for energy storage systems on the demand side, and con...

Problems solved by technology

Due to the limitation of energy density and space, energy storage containers are generally arranged relatively closely, and there is no staff to monitor the working status in the container in real time

Therefore, if the thermal runaway of the batteries in the battery cabinet causes a fire and the fire is not extinguished and cooled in time, the fire will easily spread among battery modules, battery cabinets, and even energy storage containers, resulting in large-scale fire and explosion accidents. It poses a great threat to the safety of people and property
