Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting equipment, and in particular relates to a trolley-type fire extinguisher valve protection device. Background Art

[0002] As a portable fire extinguishing tool, a fire extinguisher contains chemicals. Different types of fire extinguishers contain different ingredients. Fire extinguishers are usually stored in public places or places where fires may occur. They are designed for different fire causes and are used to extinguish fires. There are many types of fire extinguishers. According to their mobility, they can be divided into: portable and trolley types; according to the power source of the extinguishing agent, they can be divided into: gas cylinder type, pressure storage type and chemical reaction type; according to the extinguishing agent filled, they can be divided into: foam fire extinguishers, dry powder fire extinguishers, carbon dioxide fire extinguishers and water-based fire extinguishers, etc.

[0003] When a large fire occurs, a small-capacity fire extinguisher cannot meet the fire extinguishing conditions, so a larger-capacity fire extinguisher is needed. The tank of a larger-capacity fire extinguisher is heavy, so it is usually equipped with a special cart to facilitate its transportation, thus forming a cart-type fire extinguisher. Trolley-type fire extinguishers are mostly used in warehouses, cargo yards, gas stations and other places. They are very convenient to use and are generally operated by two people. When in use, two people push or pull the fire extinguisher to the burning place together, stop about ten meters away from the burning object, one person quickly removes the horn spray tube and unfolds the spray tube, then holds the handle at the root of the horn spray tube, and the other person quickly swings the switch handle of the valve to open the valve to the maximum position. The fire extinguishing method is the same as the portable method. The principle is to quickly reduce the temperature of the combustible material and isolate it from the air.

[0004] Prior art CN218961646U discloses a cart-type fire extinguisher, including a fire extinguisher assembly and a trolley assembly, the fire extinguisher assembly includes a tank, a valve and a nozzle, the upper half of the nozzle is a hose, the lower half is a hard pipe, the hose is connected to the valve outlet, and the lower end of the hard pipe is a jet port; the trolley assembly includes a frame, a roller is installed below the frame, two vertical trapezoidal brackets are symmetrically arranged above the rectangular bottom frame of the frame, a fixed crossbeam is arranged on the top of the trapezoidal bracket, an annular clamp connected to the frame is sleeved on the outer side of the tank, an annular handrail that can be pitched is arranged between the two fixed crossbeams, a gun rod that can be pitched is arranged in the center of the front of the annular handrail, a U-shaped handle is connected to the tail of the gun rod, a gun barrel is connected to the head of the gun rod, and the nozzle is arranged in the gun barrel. The cart-type fire extinguisher can be quickly operated by only one person, which can reduce personnel input, reduce operational errors, shorten firefighting time, and reduce economic losses and personal injuries caused by fire. The valve of the existing trolley fire extinguisher is installed on the top of the bottle body, and the valve lacks a protective device. Since the trolley fire extinguisher has a large volume or weight, the trolley fire extinguisher is prone to collision during movement, causing the valve to be impacted by external force, resulting in damage to the valve.
