[0002] As an important firefighting facility, underground fire hydrants are usually designed and installed outdoors, hidden in underground wells. This design not only does not affect the appearance of the city, but also effectively protects the fire hydrants from direct impact from the external environment, extending their service life. The installation location of the underground fire hydrant is close to the wellhead, and the height of the water outlet from the ground is controlled at about 30 cm. This design takes into account the convenience of firefighters to obtain water and the convenience of maintenance and use.
