Document Type and Number:
WIPO Patent Application WO/2010/123255
Kind Code:
A2
Abstract:
The present invention relates to an elevating fire hydrant assembly in which an elevating pipe automatically projects from the ground by means of water pressure when a fire hydrant is to be used, and the speed for lowering the elevating pipe projecting from the ground after use is adjustable. The elevating fire hydrant assembly comprises: a water pipe (10) which supplies firefighting water in accordance with the open/shut operation of a water control valve (70) buried underground; an elbow pipe (20) connected to the water pipe (10); a fixing pipe (30) connected to the elbow pipe (20); an elevating pipe (40) which is coupled to the fixing pipe (30) to retract into or extend from the ground, and the lower end of which is coupled to a guide block (41) that slides along the inner surface of the fixing pipe (30); a sealing pipe (31) coupled to the top of the fixing pipe (30) to prevent the elevating pipe (40) from escaping; a head block (50) which is coupled to the top of the elevating pipe (40), and which has a hose connector (51) for connecting a firefighting hose (100); and valve means for opening/shutting the lower end of the elevating pipe. The assembly enables the elevating pipe (40) to move upward by the pressure of firefighting water supplied through the water pipe (10) when the lower end of the elevating pipe (40) is shut by the valve means.
