Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire hydrant with a steerable fire-fighting interface. Background Art

[0002] Fire hydrants, formally called fire hydrants, are a type of fixed fire-fighting facility. Their main function is to control combustibles, isolate combustion-supporting materials, and eliminate fire sources. They are important fire-fighting water supply devices in cities, factories, mines, warehouses, docks, airports, traffic tunnels, high-rise buildings, etc. Fire hydrants are mainly divided into indoor fire hydrants and outdoor fire hydrants.

[0003] When using a fire hydrant, the operator usually quickly pulls out the hose and water gun (or fire hose), then connects one end of the hose to the fire interface of the fire hydrant and the other end to the water gun, and then throws the hose away and turns on the hand wheel of the fire hydrant. At this time, hold the water gun tightly and use the jet generated by the water gun to shoot water to the fire point to extinguish the fire;

[0004] During the use of existing fire hydrants, the fire interface of the fire hydrant usually needs to be connected with the water hose and the water gun, but the position of the fire interface of most fire hydrants is fixed, which may limit the connection angle and position of the water hose and the water gun, making it difficult to find a suitable connection angle in some cases, affecting the fire extinguishing effect. Some fire hydrants with steerable fire interfaces adjust the direction of the fire interface through the coordination of electric push rods and adjustment devices, thereby improving the flexibility of the fire interface. Although this driving method can self-lock after adjusting the direction of the fire interface, it also makes the internal structure of the fire hydrant with a steerable fire interface more complicated and the cost is relatively high. For this reason, we propose a fire hydrant with a steerable fire interface. Utility Model Content
