Pressure storage type fire extinguishing device and fire extinguishing method thereof

Abstract

The invention discloses a pressure storage type fire extinguishing device. The fire extinguishing device comprises fire extinguishing bottles, electrical explosion devices, valve bodies, siphons, fire extinguishing pipelines, a control terminal, a cable assembly, a flame detector, an infrared thermal imaging detector and a temperature and pressure detector, and fire extinguishing agents are stored in the fire extinguishing bottles; the electrical explosion devices are connected with the valve bodies through threads; the valve bodies are connected with the fire extinguishing bottles through threads, and tank body sealing is achieved; nitrogen or air is stored in sealed cavities formed by the fire extinguishing agents, the fire extinguishing bottles, the siphons and the valve bodies; a pressure gauge is installed on one side of each diaphragm sealing type valve body; the valve bodies are connected with the siphons through threads and connected with the fire extinguishing pipelines; and the control terminal is provided with the infrared thermal imaging detector, the temperature and pressure detector and the flame detector. By cooperating with a fire extinguishing method, the device not only has the advantages of being convenient and fast to operate, safe, efficient and the like, but also can achieve multiple times of effective fire extinguishing.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a pressure storage type fire extinguishing device and a fire extinguishing method thereof. Background technique [0002] At present, domestic automatic fire extinguishing devices are still in their infancy, and there are many problems: [0003] 1) Most automatic fire extinguishing devices cannot achieve multiple effective fire extinguishing during fire extinguishing; [0004] 2) Most of the automatic fire extinguishing devices use line type temperature detectors, temperature detectors, smoke detectors and other detection sensitivities. A small number of single-ultraviolet detectors are used as the detection unit, which cannot resist the interference of various light sources such as strong light, weak light, and flash lights in the environment during actual use, and the processing algorithm is not perfect, which makes it easy to appear automatic fire extinguishing devices...

AI Technical Summary

Problems solved by technology

[0003] 1) Most automatic fire extinguishing devices cannot achieve multiple effective fire extinguishing during fire extinguishing;

[0004] 2) Most automatic fire extinguishing devices use linear temperature detectors, temperature detectors, smoke detectors, etc. with poor detection sensitivity

A small number of single-ultraviolet detectors are used as the detection unit, which cannot resist the interference of various light sources such as strong light, weak light, and flash lights in the environment during actual use, and the processing algorithm is not perfect, which makes it easy to appear automatic fire extinguishing devices during use Malfunction;

[0005] 3) Most of the automatic fire extinguishing devices have no fault self-diagnosis function, which leads to failure to find and deal with them in time after the parts of the automatic fire extinguishing device have problems;

[0006] 4) Most automatic fire extinguishing devices have no system operation data storage function, resulting in no data and images that can be used for cause analysis after a vehicle fire occurs;

[0007] 5) At present, most automatic fire extinguishing devices have no display port and are only controlled by buttons, which leads to the inability to judge the actual situation of the protection area in time when the system alarms, which may easily lead to misjudgment;

[0008] 6) At present, the feedback signal of the fire extinguisher bottle of the automatic fire extinguishing device is single, and it is difficult to judge the state of the fire extinguisher bottle (empty bottle, faulty bottle, normal bottle) without checking the pressure gauge of the fire extinguisher bottle. Based on the above understanding, a new intelligent fire extinguisher is needed system to solve the above problems
