Description

Technical Field

[0001] The utility model relates to the technical field of fire hose cleaning, in particular to a hose cleaning device. Background Art

[0002] A fire hose is a commonly used tool in firefighting missions. It is a hose that can be used to transport high-pressure water or foam. Traditional fire hoses are lined with rubber and wrapped with linen fabric on the outside, while advanced fire hoses are made of polymer materials such as polyurethane. There are metal joints on 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. The surface of the fire hose used at the fire scene will be sticky with a lot of mud and impurities. Directly winding up the fire hose will make it difficult to store and use it for a long time. Therefore, the fire hose needs to be cleaned after use.

[0003] Traditional fire hose cleaning mainly relies on staff to use brushes and water to clean, or use hose cleaning devices. Most of the hose cleaning devices in the prior art are large in size, which is not convenient to carry with the vehicle and move at will. After the fire extinguishing task is performed, the hose cannot be cleaned in time, effectively and quickly. After a simple rinse, the hose is not thorough and clean, and needs to be brought back for re-rinsing, which greatly increases the daily work tasks of firefighters. In addition, most of the hose cleaning devices in the prior art have unsatisfactory cleaning effects on the hose. During use, the hose may become tangled, etc., and it is easy to cause inadequate cleaning. Therefore, it is necessary to design an efficient, simple and lightweight hose cleaning device to solve the above problems. Utility Model Content
