Description

Technical Field

[0001] The utility model relates to the technical field of water hose connection, in particular to a water hose connection device for a fire-fighting robot. Background Art

[0002] With the continuous development of society, fire safety issues have received increasing attention from people. The safety of people's lives and property and their livelihood are closely related to it. Most of the existing indoor fire-fighting equipment is installed on the roof of the fire sprinkler pipe. This type of equipment can only form a basket-shaped water curtain when the indoor air temperature reaches a certain value and can melt the solder on the fusible alloy lock piece. This makes it impossible to extinguish the fire in time and it is impossible to accurately determine the ignition source.

[0003] When extinguishing fires indoors, fire trucks cannot enter to extinguish fires and can only play their full role when the fire develops to a certain stage. Therefore, robots are needed to enter the fire scene to extinguish fires. However, traditional pipe docking uses snap-on docking. When the pipes are supplied over long distances, this docking method is prone to slippage due to the large pulling force, resulting in the inability to supply water remotely. Utility Model Content
