Description
Technical Field
[0001] The utility model relates to the technical field of fire fighting, in particular to an integrated multifunctional fire fighting wrench. Background Art
[0002] Common outdoor fire hydrants are mainly divided into two types: above-ground and underground. The opening and closing operations of above-ground fire hydrant covers, above-ground fire hydrant valves, and underground fire hydrant valves require the use of wrenches of different specifications. The opening and closing operations of above-ground fire hydrant covers generally use above-ground fire hydrant cover wrenches, and the opening and closing operations of above-ground fire hydrant valves generally use above-ground fire hydrant four-corner wrenches or above-ground fire hydrant five-corner wrenches. The opening and closing operations of underground fire hydrant valves generally use underground fire hydrant four-corner wrenches. The functions of fire hydrant wrenches on the market are relatively single, and can only realize the functions of a single four-corner or five-corner wrench.
[0003] Before opening the underground fire hydrant valve, the underground fire hydrant manhole cover must be opened first. Some manhole covers cannot be opened by hand due to their structure and weight, and auxiliary tools such as crowbars must be carried. In addition, some fire rescue scenes require demolition operations, which require special demolition tools.
[0004] In order to ensure the smooth progress of firefighting and rescue operations, firefighting and rescue personnel usually need to be equipped with a number of tools including ground fire hydrant wrenches, underground fire hydrant wrenches, manhole cover opening auxiliary tools, and demolition tools, which increases the workload of firefighting personnel and also poses the risk of delaying firefighting and rescue operations due to insufficient tool preparation.
