Hidden fire hydrant

Abstract

The invention discloses a hidden fire hydrant. The hidden fire hydrant comprises a concrete base platform which is cast underground, a sinking platform is formed in the concrete base platform, a firehydrant base is fixed to the portion, on the bottom surface of the sinking platform, of the concrete base platform, a vertical delivery pipe is formed on the fire hydrant base, a fire hydrant connection base is arranged at the upper side of the water delivery pipe, several water pipe interfaces are formed in the side wall of the fire hydrant connection base, a vertical external thread columnar pipe is formed on the lower end surface of the fire hydrant connection base, the water delivery pipe on the fire hydrant base is inserted into the external thread columnar pipe of the fire hydrant base,the external thread columnar pipe is in screw joint with an internal thread columnar cover, the internal thread columnar cover is inserted outside the water delivery pipe and is fixed to the fire hydrant base, a ball valve is fixedly connected to the lower end of the water delivery pipe, several annular grooves are formed in the inner wall of the lower end of the external thread columnar pipe, andsealing rings are fixedly inserted into the annular grooves of the external thread columnar pipe, and abut against the outer wall of the water deliver pipe. When the fire hydrant is not in use, the fire hydrant can be hidden underground, and it can be avoided that vehicles run down the fire hydrant.

Description

Technical field: [0001] The invention relates to the technical field of fire-fighting appliances, and more specifically relates to a concealed fire hydrant. Background technique: [0002] Fire hydrants include indoor fire hydrants and outdoor fire hydrants, and outdoor fire hydrants are further divided into above-ground fire hydrants and underground fire hydrants. The above-ground fire hydrant is fixed on the ground and is easy to use, but it affects traffic and is prone to collisions, resulting in a waste of property and resources. Although the underground fire hydrant does not have the problem of the above-ground fire hydrant, it requires firefighters to go down the well to install it. Fire hoses bring a lot of inconvenience to firefighting work. Invention content: [0003] The purpose of the present invention is exactly for the deficiencies in the prior art, and a kind of concealed fire hydrant is provided, and it can be hidden underground when not in use, avoids that ...
