Special automatic fire extinguishing apparatus for battery cases

Abstract

The present invention relates to a special automatic fire extinguishing apparatus for battery compartments. The special fire extinguishing apparatus is provided with a cylindrical shell, which is filled with a fire extinguishing agent, and is provided with a packing port, wherein the packing port is provided with a multifunctional combination valve, the multifunctional combination valve is provided with a fire extinguishing agent output channel and a gas production chamber, the gas production chamber is provided with a pressing rod, the multifunctional combination valve is provided with a handle, the handle position is provided with a position limiting shaft, the multifunctional combination valve is provided with a sealing rod, a sealing spring is arranged under the sealing rod, the multifunctional combination valve is provided with a pressure relief rod, and a pressing spring is arranged on the pressure relief rod. According to the present invention, the special automatic fire extinguishing apparatus is suitable for the fire extinguishing of battery compartments, can automatically and timely extinguish fire, and has advantages of high fire extinguishing efficiency and good safety.

Description

technical field [0001] The invention belongs to a starting device on a fire fighting equipment, in particular to a special automatic fire extinguishing device for a battery box. Background technique [0002] The automatic fire extinguishing device has a stored pressure type that uses nitrogen as a power source, and a non-storage type that converts a solid into an inert gas instantaneously. Whether it is a pressure storage type or a non-pressure storage type, the current standard requires two start-up methods: namely: manual start-up through electrical signals and automatic start-up by automatically sensing flame and temperature signals. At present, the mode of manually starting the fire extinguishing device of the stored pressure type automatic fire extinguishing device by an electric signal is all realized by a motor, and the automatic starting mode of the automatic induction flame and temperature signal is all realized by a battery (self-provided power supply). The disadv...

AI Technical Summary

Problems solved by technology

The disadvantages of these two starting methods are: 1. When a fire occurs, if the motor fails, the entire system will have no power, the manual electric starting function will fail, and the fire extinguishing device will not be able to start electrically; The loss is obvious. If the battery is used as the self-provided power supply, if the battery is not replaced in time, the fire extinguishing device will not be able to start automatically when the fire occurs; 3. The pressure gauges with the pressure relief signal output function are relatively large, thereby increasing The overall volume of the fire extinguishing device

The scope of application becomes smaller; 4. Motors, batteries (self-provided power supply), and large-volume pressure gauges will increase the overall volume of the fire extinguishing device, thereby reducing the scope of use of the fire extinguishing device
