Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrants, in particular to an outdoor fire hydrant antifreeze device. 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 sources of ignition. They are divided into indoor fire hydrants and outdoor fire hydrants. Outdoor fire hydrants are water supply facilities installed on the fire water supply network outside the building. They are mainly used for fire trucks to take water from the municipal water supply network or the outdoor fire water supply network to implement fire extinguishing. They can also be directly connected to water hoses or water guns to discharge water for fire extinguishing.

[0003] For example, the Chinese utility model provides "an antifreeze outdoor fire hydrant" announcement number: CN220644454U. The application includes a fire hydrant body and an antifreeze mechanism for preventing the fire hydrant body from freezing. The antifreeze mechanism is arranged on the outside of the fire hydrant body. The utility model sets an antifreeze mechanism. When the device is used, the photovoltaic panel converts solar energy into electrical energy and stores it in the battery. When the temperature sensor detects that the temperature inside the fixed shell is lower than the set value, the controller controls the heating coil to be energized, and the heating coil is energized to generate heat, and the temperature inside the fixed shell rises accordingly. This can effectively prevent the fire hydrant body from freezing.

[0004] In the above-mentioned technology, the antifreeze type outdoor fire hydrant adopts an antifreeze mechanism to effectively protect the surrounding area of ​​the fire hydrant from freezing. However, since the fixed shell in the antifreeze mechanism is installed on the fixed seat with bolts and other components, when personnel need to use the fire hydrant, they need to use corresponding tools to disassemble the fixed shell. The overall operation is relatively cumbersome and time-consuming, which has an adverse effect on the firefighting work of personnel. Utility Model Content
