Background

A fire hydrant, called fire hydrant formally, is a fixed fire-fighting equipment, and mainly has the functions of controlling combustible substances, isolating combustion-supporting substances and eliminating ignition sources. It is divided into indoor fire hydrant and outdoor fire hydrant. The outdoor fire hydrant is a water supply facility arranged on a fire-fighting water supply pipe network outside a building, is mainly used for a fire truck to take water from a municipal water supply pipe network or an outdoor fire-fighting water supply pipe network to put out a fire, and can also be directly connected with a water hose and a water gun to discharge water to put out a fire. Therefore, the outdoor fire hydrant system is also one of the important fire fighting facilities for fighting fire. The traditional fire hydrant is installed outdoors and lacks of a protective device, and when the fire hydrant is broken due to vehicle collision, a large amount of water leakage is caused, and the loss is increased.

The prior art has the protection device for protecting the fire hydrant, but the prior fire hydrant protection device generally reduces the impact force of a vehicle on the fire hydrant by arranging a buffering and damping mechanism; in order to obtain a better buffering and damping effect, more elastic parts are generally required to be arranged, and the protection device has a larger volume and needs to occupy a larger installation space due to the arrangement of more elastic parts; moreover, the protection effect of the conventional protection device is mainly embodied in that the impact strength is reduced after the collision, only the damage strength caused after the collision is reduced, and the probability of collision cannot be reduced.
