Outdoor fire hydrant protection device

Abstract

The invention discloses an outdoor fire hydrant protection device. The outdoor fire hydrant protection device comprises a plurality of protection rods and a plurality of mounting frames. The pluralityof mounting frames are embedded in the ground and are in one-to-one correspondence with the protection rods. Rotating rods are horizontally and rotationally installed in the mounting frames and are each vertically and fixedly connected with a plurality of extrusion rods, and a plurality of pressure-sensitive pieces are fixedly installed on the side wall of each mounting frame. The distances between all points on each pressure-sensitive piece and the corresponding rotating rod are different, the extrusion rods make extrusion contact with the pressure-sensitive pieces, and each mounting frame is connected with a plurality of mounting pipes. A movable block is hermetically and slidably mounted in each mounting pipe, the upper ends of the movable blocks extend out of the ground, and the lowerends of the movable blocks are fixedly connected with rack rods. The rack rods are in engaged connection with gears, and the gears fixedly sleeve the rotating rod. According to the device, when a vehicle continuously gets close to a fire hydrant, an expanded air bag has a good buffering effect, and when no vehicle approaches, the air bag contracts, so that the occupied space of the protection device is small.

Description

technical field [0001] The invention belongs to the technical field of fire hydrants, in particular to an outdoor fire hydrant protection device. Background technique [0002] Fire hydrant, officially called fire hydrant, is a fixed fire-fighting facility whose main function is to control combustibles, isolate combustion-supporting materials, and eliminate ignition sources. There are indoor fire hydrants and outdoor fire hydrants. The outdoor fire hydrant is a water supply facility installed on the fire water supply pipe network outside the building. It is mainly used for fire trucks to take water from the municipal water supply pipe network or outdoor fire water supply pipe network for fire extinguishing. It can also be directly connected to a hose or a water gun to extinguish fire. Therefore, the outdoor fire hydrant system is also one of the important fire-fighting facilities for fighting fires. Traditional fire hydrants are installed outdoors and lack protective device...

AI Technical Summary

Problems solved by technology

The traditional fire hydrant is installed outdoors and lacks protective devices. When it breaks when it encounters a vehicle collision, it will cause a lot of water leakage and increase losses.

[0003] In order to protect the fire hydrant, protective devices have appeared in the prior art, but the existing fire hydrant protection devices generally reduce the impact of the vehicle on the fire hydrant by setting a buffer and shock absorbing mechanism; in order to obtain a better buffer and shock absorption effect, Usually, more elastic parts need to be installed, and the installation of more elastic parts makes the protective device larger in size and needs to occupy a relatively large installation space; and the protective effect of the existing protective device is mainly reflected in reducing the impact force after the impact , only reduces the damage caused by the impact, but does not reduce the probability of collision
