Temperature and pressure releasing fire extinguishing device

Abstract

The invention discloses a temperature and pressure releasing fire extinguishing device. The temperature and pressure releasing fire extinguishing device comprises an annular packaging layer and a medicine column. The annular packaging layer forms an annular sealed space filled with a fire extinguishing agent, and the fire extinguishing agent is in a liquid state at the normal temperature. The medicine column is installed in an inner ring of the annular packaging layer, the medicine column is provided with an ignition device which is an electronic control element. When the ignition device is ina working state, the medicine column spontaneously burns and gives out heat. According to the temperature and pressure releasing fire extinguishing device, self-spraying under the high-temperature condition is achieved, and the technical problems that in the prior art, a gas fire extinguishing agent applied to disturbing and damaging of a lithium battery is large in size and the like are solved.By means of the temperature and pressure releasing fire extinguishing device, manual intervention is not needed in the fire extinguishing process, and fire extinguishing and cooling functions can be reliably and rapidly achieved in real time after a fire disaster happens.

Description

technical field [0001] The invention relates to the technical field of automatic fire extinguishing, in particular to a fire extinguishing device for releasing temperature and pressure. Background technique [0002] In recent years, with the rapid development of the new energy industry, new energy vehicles are also on the fast track, and the number of new energy vehicles is increasing year by year. Due to the increase of new energy vehicles, fire incidents of new energy vehicles are also increasing year by year. The main reason is that the inherent activity of lithium batteries makes the batteries unstable. When they are squeezed, collided, short-circuited, etc., it is easy to cause the battery to catch fire and cause huge damage. Personal and property losses, while bringing a great negative impact on social stability. With the rapid development of the new energy industry, there is an urgent need for a technology that can effectively extinguish fires. At the same time, acti...
