Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher technology, and more specifically, to a portable high-pressure fine water mist fire extinguisher. Background Technology

[0002] Throughout history, many ancient buildings have been destroyed by fire, causing severe damage to our precious historical and cultural heritage, and the lessons learned are extremely painful. Ancient buildings in my country are widely distributed, mostly of wooden structure, posing a significant inherent fire hazard. Once a fire breaks out, due to their low fire resistance, high fire load, and clustered distribution, they are extremely prone to spreading rapidly. Most ancient buildings are also far from towns, nestled in mountains and lacking water, which is very unfavorable for firefighting. Even the few ancient buildings near towns often lack fire lanes due to high walls, layered steps, narrow doorways, and high thresholds, delaying firefighting efforts. To mitigate these problems, high-pressure water mist fire extinguishers were developed.

[0003] However, most traditional high-pressure fine water mist fire extinguishers are just simple bodies, which makes them difficult to pick up and carry due to their smooth surfaces, thus affecting their portability.

[0004] Furthermore, high-pressure fine water mist fire extinguishers need to be connected to external water pipes during use. However, the connection method is often fixed by simple structures such as flanges. This fixing method results in poor sealing at the connection point, leading to water leakage and affecting normal fire extinguishing. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a portable high-pressure fine water mist fire extinguisher with the following advantages:

[0018] 1. By setting up a housing, a square shell, an electric push rod, and connecting screws, when the fire extinguisher body needs to be carried, the electric push rod can be controlled to lower the square shell and let it enter the housing. Then, the bottom of the connecting screw is screwed into the threaded hole by turning the block to fix the square shell and the housing, which facilitates subsequent carrying.

[0019] 2. By setting up a water pipe, a first conical surface, a second conical surface, and a clamping nut, when it is necessary to connect the fire extinguisher body to the water pipe, the first conical surface on the water pipe can be directly inserted into the second conical surface on the outer pipe. Then, tighten the clamping nut to make its interior press against the retaining ring, so that the inner wall of the first conical surface abuts against the inner wall of the second conical surface, thereby increasing the sealing of its connection position and preventing water leakage.

[0020] 3. By setting up shock-absorbing seats, rubber blocks, and shock-absorbing springs, when the fire extinguisher body is in use, the vibration generated by it will be transmitted to the upper end of the shock-absorbing seats. At this time, the rubber blocks and shock-absorbing springs inside the cavity will absorb the vibration emitted by the fire extinguisher body, preventing resonance and helping to reduce noise.
