Description

Technical Field

[0001] The invention relates to the technical field of firefighting and rescue, in particular to an inflatable conversion water gun for firefighting and rescue. Background Art

[0002] In firefighting and rescue work, various complex and dangerous scenarios place extremely high demands on the performance and functions of rescue equipment. Deep well and complex tunnel rescue is one of the most challenging scenarios. In the past, during deep well rescue, due to the narrow space and large depth, the existing gas supply equipment could hardly achieve long-distance and accurate gas supply. Firefighters often faced insufficient or unstable gas supply, which not only affected the rescue progress, but also posed a serious threat to the lives of firefighters.

[0003] In complex tunnel rescue operations, the internal structure of the tunnel is intricate and filled with toxic and harmful gases. Traditional equipment is unable to quickly and effectively purge and replace the toxic and harmful gases in the tunnel, causing rescue workers to be extremely vulnerable to toxic gases when entering the tunnel. For example, in some tunnel rescue operations after fires, toxic gases such as carbon monoxide produced by combustion accumulate for a long time. If they cannot be replaced in time, the risk of poisoning for firefighters during the rescue process will increase significantly.

[0004] There are also many problems in water rescue. When intercepting floating objects downstream, the lack of specialized and effective tools makes it difficult to quickly and efficiently combine water hoses into devices with good interception effects. After an oil leak in open waters, existing equipment makes it difficult to quickly produce effective fences to prevent further spread of oil pollution, causing great harm to the environment.

[0005] In addition, in the sealing performance testing of on-duty fire hoses, the existing testing methods have problems such as cumbersome operation and inaccurate test results; and when carrying out internal attack and firefighting under the cover of water guns, once the officers and soldiers are trapped and the air respirator is exhausted, the existing equipment cannot provide continuous air supply to the trapped firefighters in a timely and convenient manner, which severely compresses the rescue time and reduces the chance of survival of the trapped people.

[0006] Based on the above shortcomings of existing firefighting and rescue equipment in practical applications, it is urgent to develop an equipment such as a firefighting and rescue inflatable conversion water gun that can effectively solve the above problems; it needs to have a simple and efficient connection method, reliable sealing performance, and the ability to adapt to a variety of complex rescue scenarios, so as to improve the overall combat effectiveness of firefighting and rescue, ensure the life safety of firefighters and improve the success rate of rescue work. Therefore, a firefighting and rescue inflatable conversion water gun is proposed to solve the above-mentioned problems. Summary of the invention

[0046] A fire rescue inflatable conversion water gun actual rescue application stage:

[0047] 1. Deep well and complex tunnel rescue: When used for deep well and complex tunnel rescue, the inflated hose 3 transports air to the operation point over a long distance. On the one hand, the continuous airflow provides firefighters with sufficient breathing gas to ensure their normal breathing in a limited space; on the other hand, the airflow is used to push the original toxic and harmful gases in the tunnel out, achieving the purpose of rapid blowing and replacement, purifying the working environment, and reducing the risk of poisoning of firefighters.

[0048] 2. Water rescue: When making downstream interception floating hoses for water rescue, the inflated hose 3 has buoyancy due to the gas inside and can float on the water surface; firefighters connect multiple sections of hoses in sequence and arrange them in appropriate positions to form an interception barrier to intercept floating objects and prevent them from further spreading. After an oil leak in open waters, the floating characteristics of the hoses are also used to arrange hoses around the leaking area to form a fence to prevent the oil from continuing to pollute the surrounding waters.

Fire extinguishing and auxiliary rescue with water gun: Firefighters operate by holding the water gun 4, with the shoulder strap 404 of the water gun 4 slung across the body to reduce the burden of long-term holding, and the protective cover 405 increases the friction between the hand and the water gun 4, making the firefighter more stable when operating the water gun 4; according to actual rescue needs, by adjusting the water outlet 402 of the water gun 4, different forms of water flow can be sprayed out, such as direct current for extinguishing fire at the root of the fire source, and spray for controlling the spread of fire, cooling and protecting the firefighter's own safety, etc., to cope with different fire scenes and improve the effect of fire extinguishing and rescue.

[0050] To sum up, the fire rescue inflatable conversion water gun, through the quick clip-on connector 5, realizes the rapid assembly between the air respirator 1, the medium pressure air supply interface 2, the water hose 3 and the water gun 4, which greatly shortens the rescue preparation time. The sealing kit 6 installed between every two quick clip-on connectors 5 ensures the high air tightness of the entire system, effectively prevents gas leakage, ensures stable air supply, and provides basic guarantee for the smooth implementation of the rescue operation. In addition, the equipment has a simple structure and a compact size. Officers and fighters can operate and use it with simple training, and daily maintenance is convenient, and only needs to be wiped and checked for air tightness.

[0051] In addition, through the air breathing apparatus 1, the medium-pressure air supply interface 2, the water hose 3 and the water gun 4, the quick-connect head 106 on the air breathing apparatus 1 is tightly connected to the medium-pressure air supply interface 2 by means of threads, one end of the medium-pressure air supply interface 2 is clamped with the water hose 3, and the other end of the water hose 3 is connected to the water gun 4. Then the firefighter opens the explosion-proof bottle valve 103 of the air breathing apparatus 1 to allow the gas in the bottle to enter the water hose 3 through the medium-pressure air supply interface 2. When used for deep well and complex tunnel rescue, the inflated water hose 3 transports the air to the operation point over a long distance. On the one hand, the continuous airflow provides the firefighters with sufficient breathing gas to ensure their normal breathing in a limited space; on the other hand, the airflow is used to push the original toxic and harmful gases in the tunnel to be discharged, so as to achieve the purpose of rapid blowing and replacement, purify the working environment, and reduce the risk of poisoning of firefighters.
