Embodiment Construction

[0027] In order to overcome the fire-prone safety hazards in the power battery compartment of new energy pure electric vehicles, a vehicle power battery compartment fire extinguishing system is proposed. The above-mentioned vehicle power battery compartment fire extinguishing system will be further elaborated below through specific implementation methods.

[0028] see figure 1 , a vehicle power battery compartment fire extinguishing system 100 according to an embodiment includes a fire extinguishing device 110 , a fire extinguishing agent delivery pipe 120 , a thermal sensor 130 , a signal converter 140 and a junction box 150 .

[0029] The fire extinguishing device 110 is arranged in the vehicle power battery compartment. The fire extinguishing device 110 may be a thermal aerosol fire extinguisher, a dry powder fire extinguisher, or an ultra-fine dry powder fire extinguisher. The ultrafine dry powder fire extinguishing agent of the ultrafine dry powder fire extinguisher is n...

Abstract

The invention relates to an automobile motive power battery compartment fire extinguishing system, which comprises a fire extinguishing device, a fire extinguishing agent conveying pipe, a signal converter and a thermosensitive element, wherein the fire extinguishing device is arranged in an automobile motive power battery compartment, the fire extinguishing agent conveying pipe is communicated with a spraying opening of the fire extinguishing device, the signal converter is electrically connected with the fire extinguishing device, and the thermosensitive element is used for detecting the temperature in the automobile motive power battery compartment and transmits the temperature value to the signal converter. When the temperature value is higher than a set threshold value, the signal converter converts the temperature value into fire extinguishing device starting signals and sends the fire extinguishing device starting signals to the fire extinguishing device, and a fire extinguishing agent is sprayed into the automobile motive power battery compartment through the fire extinguishing agent conveying pipe after the fire extinguishing device receives the fire extinguishing device starting signals. Through the temperature detection by the thermosensitive element and the signal conversion and the signal sending by the signal converter, the fire extinguishing device can be automatically started in time, the fire extinguishing agent is conveyed to the fire extinguishing agent conveying pipe and is sprayed out to the automobile motive power battery compartment, the local or full submerging state is formed in the automobile motive power battery compartment, fire can be automatically extinguished in time, the fire extinguishing efficiency is high, and the safety is good.

Description

【Technical field】 [0001] The invention relates to the technical field of vehicle fire protection, in particular to a fire extinguishing system for an automobile power battery compartment. 【Background technique】 [0002] In new energy pure electric vehicles, the protection of power batteries has always been an important issue. When the vehicle is running, the power battery is outputting current and dissipating heat. In the sealed power battery compartment, especially in hot summer, the continuously accumulated heat will cause the temperature of the power battery compartment to rise. The wiring harness in the power battery compartment is due to its own temperature, the heat emitted by the power battery, and the high temperature of the environment , easy to catch fire and cause a fire. The fire will not only damage the key components in the power battery compartment, but even cause casualties, which poses a serious safety hazard. [0003] Portable dry powder fire extinguishe...
