Abstract
The invention relates to a fine water mist fire gun with a telescopic gun body. The problems that existing individual fire extinguishing equipment is short in operating distance, prone to hurting human bodies during operation and high in fire extinguishing agent cost are solved. The fine water mist fire gun comprises a folding ancon, a switch, a carrying handle, a first-class pipe, a second-class pipe, a third-class pipe, a pinch plate, a nozzle and the like together. When the fine water mist fire gun does not work, the third-class pipe is compressed and further fixed with the pinch plate, so that storage space is reduced, and transportation and carrying are made more convenient; in the working process, the second-class pipe and the third-class pipe can be extended to be adjusted to a proper distance and then are fixed with the pinch plate; and low-pressure gas can generate high-speed airflow through the nozzle to be mixed with water in a nozzle mixing cavity so that fine water mist can be formed to act on a fire. The fine water mist fire gun has the advantages that first, the gun body can be extended to increase the distance between people and a fire source in the working process, and thus the safety coefficient is high; second, a fire extinguishing agent is normal pressure water, cost is low and supplementing is easy; third, water acts on the fire in a fine water mist mode, the cooling effect is good, and the water utilization rate is high; and fourth, the gun body can be contracted when the fire gun does not work, and hence carrying and transportation are made convenient.
Description
Technical field
The present invention relates to a kind of telescopic fine mist fire-fighting rifle of increase operating distance, is especially adapted for use in grassland earth's surface fire and gloomy
The little flare of forest fires calamity puts out.
Background technology
Because the forest reserves more than 98% are grown in mountain area, chain of mountains rows of mountains, ravines and guillies criss-cross, existing forest extinguishing equipment is deposited on market
In many defects, both it had been not easy to the portable in forest environment and had shuttled, while operate the personnel of fire-fighting equipment nearer apart from burning things which may cause a fire disaster,
It cannot be guaranteed that the safety of fire extinguishing personnel, and fire extinguishing to be equipped in fire extinguishing procedure the consumption to extinguishing chemical larger, it is impossible to very well
Ground adapts to supply the reality of difficulty under forest environment, or even some extinguishing chemicals can cause environmental pollution, therefore existing fire extinguishing dress
The standby needs that can not meet forest environment.Still lack one kind on market and can ensure that personal security, portable convenience,
The environmentally friendly individual soldier fire extinguishing equipment of the service efficiency of extinguishing chemical can be improved again.
The content of the invention
To solve existing Fire extinguisher portable inconvenience, fire-fighting efficiency is not high, the low problem of safety coefficient, and the present invention is using scalable
Body of a gun structure, not only can in good time adjust quenching distance, rapidly and thoroughly put out a fire, moreover it is possible to ensure personal security, and the present invention
When not working, the body of a gun is shunk, be easy to portable, transport to take up room little；Extinguishing chemical is aqua, pollution-free and low cost；
Power is provided using low-pressure gas and produce water mists, improve the utilization rate of aqua, reduce rescue supply pressure.The present invention has peace
Overall coefficient is high, and fire-fighting efficiency is high, pollution-free, the features such as easy to operate.
The technical solution adopted for the present invention to solve the technical problems is：Ancon, switch and carrying handle are used in combination can carry out singlehanded behaviour
Make；The body of a gun of fire gun adopts three-level telescoping tube, the rope pulley mechanism in the pipe of the second level triode road can be driven to move, reached
The telescopic purpose of the body of a gun；The nozzle of fire gun adopts reducing and expansion type jet pipe, improves air velocity, forms high velocity air and mixed
Close formation negative pressuren zone in chamber and water is drawn into hybrid chamber and High-speed gas impacting formation water mists, reach the purpose of high-effect fire-extinguishing.
The invention has the beneficial effects as follows：Ancon, switch and carrying handle are used in combination achievable one-handed performance；Using the extension type body of a gun
Both portable it had been easy to, had been also beneficial to efficient fire extinguishing, while improves safety effect distance；Reducing and expansion type jet pipe obtains the efficiency of fire extinguishing
Very big raising.
