Device for preventing fire hydrant from being damaged by impacting

Abstract

The invention relates to the technical field of security and protection, and discloses a device for preventing a fire hydrant from being damaged by impacting. The device comprises a column base, wherein the outer surface of the column base is fixedly connected with the ground, the lower half section of the column base is located in the ground, a water conveying pipe is arranged in an inner cavityof the column base, the upper end of the inner cavity of the column base is movably connected with a spherical valve located above the water conveying pipe, and the upper end of the inner cavity of the column base is fixedly connected with a second fixed magnet located above the spherical valve. By a rotary fire hydrant, when the upper end of the fire hydrant is greatly impacted, a fire-fighting column can rotate around a second rotating shaft to prevent rigid damage to the fire-fighting column; meanwhile, through transmission of a transmission belt, the spherical valve synchronously rotates under transmission of the second rotating shaft, the water conveying pipe is closed through the spherical valve, leakage of a large amount of water resources is avoided, the situation that after a traditional fire hydrant is greatly impacted, the fire hydrant is broken, and leakage of a large amount of water resources is caused is avoided, and the service life of the fire hydrant is guaranteed.

Description

technical field [0001] The invention relates to the technical field of security, in particular to an impact damage prevention device for a fire hydrant. Background technique [0002] A fire hydrant, officially called a fire hydrant, is a fixed fire-fighting facility whose main function is to control combustibles, isolate combustion-supporting substances, and eliminate ignition sources. Fire hydrants are divided into indoor fire hydrants and outdoor fire hydrants according to the application. . [0003] The use method of outdoor fire hydrant is to first open the water bag opening link switch of the fire hydrant with a wrench, then connect the fire water bag, then open the water outlet valve switch with a wrench, and connect the water bag mouth and the water outlet gun head, then the fire can be controlled. Water spraying is carried out on site, but because the outdoor fire hydrant is usually set up next to the main street, the contact of some vehicles and other objects will...
