Description

technical field

[0001] The invention relates to a safety fire hydrant, which belongs to fire fighting equipment. Background technique

[0002] With the rapid development of my country's economic construction and the continuous improvement of the country's fire safety regulations, the public's awareness of fire protection is increasing, and road fire hydrants have become one of the necessary basic fire protection facilities for cities and industrial and mining enterprises. Due to the particularity and density of fire hydrants installed on both sides of the road, it is required to be installed along the road, close to the intersection, with a distance of no more than 200 meters. The waste of precious water resources, and bring inconvenience to people's life, time-consuming maintenance replacement and water supply pipeline stop water, bring hidden danger to fire safety. Relevant data show that there are basically four types of vehicle collisions: frontal collision, side collis...
