Description

Technical Field

[0001] The utility model relates to the technical field of fire hoses, in particular to a quick leak-stopping device for fire hoses. Background Art

[0002] Is a fire hose a hose used to transport flame-retardant liquids such as high-pressure water or foam? Fire hoses are divided into two categories: lined fire hoses and leaking fire hoses. Traditional fire hoses are lined with rubber and wrapped with linen woven fabric on the outside, while advanced fire hoses are made of polymer materials such as polyurethane. There are metal joints at both ends of the fire hose, which can be connected to another hose to extend the distance or connected to a nozzle to increase the liquid injection pressure. Fire hoses may be damaged and leak due to various reasons during use. Once a fire hose leaks, it will inevitably affect the effect of the fire extinguishing operation, and a quick leak plugging device is needed to plug the damaged part.

[0003] The Chinese patent publication number is CN214384304U, and the authorization announcement date is October 12, 2021. A quick leak plugging device for a fire hose includes a connecting shaft and a mounting box, one side of the connecting shaft is movably connected with a first fastener and a second fastener, an air bag is arranged in the mounting box, a trachea is plugged into the top of the air bag, a fixing plate is fixedly connected to the inner wall of one side of the mounting box, an air pump is fixedly connected to the upper surface of the fixing plate, and one end of the trachea is plugged into the air pump, and a sliding rod is plugged into the bottom of the air pump, and one end of the sliding rod passes through the fixing plate and is movably connected to a spring. The utility model can not only inflate the air bag with an air pump, so that the air bag can block and protect the damaged part of the water hose to prevent the damaged mouth from increasing due to friction, but also can fix the pressure ring on the damaged part of the water hose by adjusting the fastening bolt to prevent water from overflowing, and can also make the mounting box slide in the slide slot, so that the air bag can block and protect different damaged parts of the water hose, thereby improving the efficiency of leak plugging.

[0004] The existing fire hose plugging is achieved by screwing screws into the fire hose to quickly plug the fire hose leak. The water pressure of the fire hose increases during use, and the water pressure exerts pressure on the screws, causing the screws to fall off, resulting in larger damage to the fire hose, reducing the fire hose leak plugging effect, and cannot meet usage requirements.
