Detonation device for firefighting and fire extinguishing

Abstract

The invention belongs to the field of firefighting and particularly relates to a detonation device for firefighting and fire extinguishing. The detonation device comprises a compression gas bottle anda delayed inflation unit, the compression gas bottle communicates with the delayed inflation unit, and the delayed inflation unit is provided with a triggering device and an exhaust port; and the delayed inflation unit is assembled in the mode that when the triggering unit is not triggered, the compression gas bottle is disconnected with the exhaust port, and when the triggering device is triggered, the delayed inflation unit can make the compression gas bottle to communicate with the exhaust port after a period of set time. The delayed inflation device is adopted to conduct delayed detonation on a water bag, only by activating the delayed inflation device before the water bag is thrown, the water bag can be detonated automatically by the delayed inflation device after the predetermined time, open fire is not generated by adopting high-pressure gas for detonation, and secondary disaster is avoided while it is guaranteed that the water bag is fully burst.

Description

technical field [0001] The invention belongs to the field of fire fighting, and in particular relates to a detonating device for fire fighting and extinguishing. Background technique [0002] Forest fires generally occur in remote areas with dense vegetation, and the burning area is large and the spread speed is fast. Therefore, it is difficult to use artificial ground fighting to extinguish the fire. In the prior art, helicopter buckets are mainly used to sprinkle and extinguish the fire area, but the buckets in the prior art still have many defects in the actual use process: first, the helicopter generally selects the nearest water intake point to fetch water on the spot, and the bucket is always used when fetching water. Hanging under the helicopter, so the helicopter needs to keep hovering for a long time during the water intake process, which not only affects the efficiency of fire fighting, but also has a greater safety risk for the helicopter to hover for a long time ...

Problems solved by technology

In the prior art, helicopter buckets are mainly used to sprinkle and extinguish the fire area, but the buckets in the prior art still have many defects in the actual use process: first, the helicopter generally selects the nearest water intake point to fetch water on the spot, and the bucket is always used when fetching water. Hanging under the helicopter, so the helicopter needs to keep hovering for a long time during the water intake process, which not only affects the efficiency of fire fighting, but also has a greater safety risk for the helicopter to hover for a long time in an uncertain environment; second, the existing technology When the bucket in the bucket is splashing, the water in the bucket will not gushes out all at once, but will pour slowly like a waterfall, and the helicopter is not suitable for hovering over the fire scene, and usually directly skips over the fire scene, so it will As a result, the amount of water poured per unit area of ​​the fire scene is insufficient, and it is difficult to suppress the fire. In addition, the water flow will be atomized during the pouring process, and the water mist is easily decomposed into hydrogen and oxygen when it encounters high temperature, resulting in deflagration and aggravating the fire; Third, in order to improve the fire extinguishing effect, fire extinguishing agent is generally added to the bucket. However, due to the different water quality conditions at different water intake points, the fire extinguishing agent may fail after mixing with water for a long time, especially the distance between the water intake point and the fire scene. In the case of a long distance, the fire extinguishing agent has sufficient time to react with the chemical substances in the water during transportation, which further increases the risk of fire extinguishing agent failure
