Example Embodiment

[0031] Example one:

[0032] Please refer to figure 1 This embodiment provides a nozzle for fire protection of a lithium battery box. The nozzle includes a nozzle body 1 and a nozzle core 2. The nozzle core 2 is arranged in the nozzle body 1, and further includes an elastic member 6 and a nozzle orifice plate 3. Wherein, a first flow passage 11 is formed inside the nozzle body 1, and the first end of the nozzle body 1 is used to connect with the pipe, so that the first end of the first flow passage 11 is connected with the pipe for transmitting the fire extinguishing agent, and the other end of the pipe is connected to the fire extinguishing agent. The second end of the nozzle body 1 is in communication with the nozzle orifice plate 3, and the nozzle orifice plate 3 is provided with at least one spray hole 41 for spraying the fire extinguishing agent flowing out from the second end of the first flow channel 11. Fire out the lithium battery.

Abstract

The invention relates to the technical field of lithium batteries, in particular to a nozzle for fire fighting of a lithium battery box and a lithium battery with a fireproof function. The nozzle comprises a nozzle body, a nozzle core, an elastic member and a nozzle orifice plate, wherein the nozzle core is arranged in a first flow passage of the nozzle body through the elastic member; under the normal condition, the elastic member abuts against the nozzle core when positioned at a first deformation, so that the nozzle core is in sealing contact with the inner wall of a sealing section of thefirst flow passage so as to enable the interior of a battery box body to be in the sealing state, and the sealing requirement of the lithium battery is met; and when the lithium battery fires, the elastic member is compressed by the pressure generated when a fire extinguishing agent is released, the nozzle core exits from the sealing section of the first flow passage, the sealing effect fails, thefire extinguishing agent can be smoothly conveyed to the nozzle orifice plate through the first flow passage, and the fire extinguishing agent is sprayed to the battery box body through spraying holes in the nozzle orifice plate, so that the automatic fire extinguishing effect is achieved, the occurrence of the fire is avoided, and the personal safety of users is guaranteed.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a fire-fighting nozzle for a lithium battery box and a lithium battery with a fireproof function. Background technique [0002] In recent years, with the continuous development of our country's economy, the continuous progress of society. With the rapid development of the country's new energy industry, more and more new energy power battery vehicles based on lithium batteries, energy storage power stations, and charging piles are changing people's lives. [0003] At present, new energy lithium batteries, as a supplement and replacement of traditional energy sources, are the trend of social development. my country's government also gives strong support to the new energy electric vehicle travel and energy storage power station "shaving peaks and filling valleys". The industry is developing rapidly, the scope of use is becoming wider and wider, and the installed capacity...
