[0004] The purpose of this application is to address the problem that existing compressed nitrogen foam fire extinguishing devices, which can be charged and swapped, have many hoses, making them inconvenient for firefighting and rescue operations. These hoses also swing around during transportation and firefighting, affecting the time and efficiency of firefighters in the overall firefighting and rescue efforts. The application provides a compressed nitrogen foam fire extinguishing device suitable for charging and swapping cabinets.
[0005] The technical solution adopted in this application is as follows: a compressed nitrogen foam fire extinguishing device suitable for charging and swapping cabinets, wherein a fixing ring is fixedly installed on the surface of the foam tank body, a back plate is fixedly connected to one side surface of the fixing ring, an arc-shaped fixing plate for foam hose is fixedly installed on the side of the back plate away from the foam tank body, a connecting shaft is provided at the edge of the surface of the arc-shaped fixing plate for foam hose, and a limiting arc plate is fixedly installed on the surface of the connecting shaft.
[0006] By adopting the above technical solution, when firefighters use fire extinguishing equipment for fire fighting and rescue, the strong pressure will cause the foam tank hose to shake randomly during the fire fighting process, affecting the firefighters' accurate fire fighting. During the use of this device, firefighters can install the foam tank hose on the surface of the foam hose arc fixing plate and close the upper limit arc plate to position the foam tank hose. The hose fixing can ensure that the hose will not swing or fall off randomly during the fire fighting process, thereby improving the stability and accuracy of the fire fighting operation.

[0008] By adopting the above technical solutions, the spray gun can efficiently spray foam to quickly cover the flame surface, isolate oxygen, and effectively extinguish the fire. The spray gun has a long spray distance, which is many times that of ordinary fire extinguishers, allowing firefighters to stay away from the fire source and ensure their safety.
[0009] In a preferred embodiment, an oxygen tank is fixedly installed on the inner wall surface of the fixing ring adjacent to the foam tank body, and an oxygen hose is fixedly connected to the upper surface of the oxygen tank.
[0010] By adopting the above technical solution, the oxygen cylinder provides firefighters with the oxygen needed for normal breathing in oxygen-deficient or high-concentration toxic gas environments.

The limit ring has a threaded hole on its surface, and a fixing bolt is movably inserted into the surface of the threaded hole.
[0012] By adopting the above technical solution, when firefighters are carrying out firefighting and rescue operations, the oxygen hose can be limited within the limiting ring. The diameter of the limiting ring can be adjusted by using fixing bolts to adjust the diameter of the oxygen hose, which makes it convenient for firefighters to use in a timely manner without affecting their firefighting efficiency.
[0013] In a preferred embodiment, a compressed nitrogen tank is fixedly installed adjacent to the foam tank body, a nitrogen transmission hose is fixedly installed on the upper surface of the compressed nitrogen tank, and the foam tank body is fixedly installed at the end of the nitrogen transmission hose.
[0014] By adopting the above technical solution, the nitrogen cylinder provides the necessary driving gas for the fire extinguishing device, enabling the extinguishing agent to be smoothly sprayed to the fire source and achieve rapid fire extinguishing. As an inert gas, nitrogen does not burn or support combustion. After being injected into the fire scene, it can quickly reduce the oxygen concentration and inhibit the spread of fire, thereby enhancing the fire extinguishing effect.
[0015] In a preferred embodiment, a first U-shaped support plate is fixedly connected to the surface of the compressed nitrogen tank, an oxygen hose fixing plate is welded to the surface of the first U-shaped support plate, an elastic band is provided on the upper surface of the oxygen hose fixing plate, a limit hole is formed on the surface of the elastic band, and a fixing buckle is movably installed on the surface of the elastic band.
[0016] By adopting the above technical solution, after the nitrogen is used up, it is also necessary to store the nitrogen transmission hose to facilitate firefighters to better transport and extinguish the fire with the whole fire extinguishing device.

[0018] By adopting the above technical solution, the carrying strap design allows the fire extinguishing device to be easily carried on the back of firefighters, freeing their hands and facilitating rapid movement and fire extinguishing operations at the fire scene.
[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:
[0020] In this application, when firefighters use fire extinguishing equipment for fire fighting and rescue, the strong pressure can cause the foam can hose to sway freely during the fire fighting process, affecting the firefighters' accurate fire fighting at the fire point. During the use of this device, firefighters can install the foam can hose on the surface of the foam hose arc fixing plate and close the upper limit arc plate to position the foam can hose. The hose fixing can ensure that the hose will not swing or fall off during the fire fighting process, thereby improving the stability and accuracy of the fire fighting operation.
[0021] The spray gun can efficiently spray foam to quickly cover the flame surface, cut off oxygen, and effectively extinguish the fire. The spray gun has a much longer spray distance than ordinary fire extinguishers, allowing firefighters to stay away from the fire source and ensuring their safety. Oxygen cylinders provide firefighters with the oxygen needed for normal breathing in oxygen-deficient or highly toxic gas environments. Firefighters install oxygen masks at the end of the oxygen hose to ensure their safety and improve firefighting efficiency. Attached Figure Description
