The present invention relates to a fire hydrant installed in the ground, and more particularly, to minimize the installation area by storing the drum wrapped around the fire hose lay on the inner side of the fire hydrant, in the case of fire use including fire extinguishing direction or water jet direction It is related to an elevated hose reel hydrant capable of rotating the drum left and right according to the condition to freely rotate the drum from side to side.

In general, outdoor fire hydrants are disaster prevention facilities that supply fire water for extinguishing fires. However, outdoor fire hydrants should be constructed in a durable structure and method so that they can be maintained, repaired and used for a long time after being installed. It should not be exposed to freezing, damage, breakage, freezing of fire extinguishing water, etc., and should be kept available for use at any time.

However, the underground fire hydrant installs a manhole and installs a fire hydrant in the manhole, which requires a lot of construction cost, longer air, and open a heavy-cast manhole cover for emergency use. It is inconvenient to use because it has to be combined, and there is a possibility of freezing in winter because there exists a space even if it is installed in the manhole, and there is a case where the pipe freezes in case of fire and it cannot be used. It is cheaper, but generally, it is made of heavy gray cast iron castings to withstand strong hydraulic pressure and corrosion resistance, making it difficult to handle by manpower during construction, weak to breakage by impact, and protruding body on the ground, which may cause freezing and freezing. It is generally installed at a position where it is in contact with the roadway of the pedestrian passage side. It may cause inconvenience to traffic and parking of the vehicle, and may be damaged by contact with heavy moving objects such as the vehicle, and may be exposed to the outdoors, causing damage and corrosion of important operating parts, making it difficult to use in an emergency. It is pointed out as a problem, and after the fire hydrant is constructed, repair and repair frequently occur, which causes a large cost in maintenance.

Prevents the danger of pedestrians, and facilitates pedestrians' traffic, but requires much construction cost and air due to manhole installation, exposes to the risk of freezing and freezing in winter, and hydrant valves are attached to the vertical piston cylinder. As the piston rod and the locking plate are installed, the cost of manufacturing the fire hydrant is increased and the sudden fire hydrant rising shock due to the water pressure caused by the sudden operation of the water dispenser valve is to be sustained. Even if the type piston cylinder body disassembles the piston rod, It cannot be removed, so the internal parts of the fire hydrant cannot be repaired or replaced.

The hoisting fire hydrant with drum rotation, published in Utility Model Application No. 2003-0006185, is installed in a manhole like underground fire hydrant, thus preventing the risk of damage and damage of the ground fire hydrant. However, the construction cost and air consumption are high, exposed to the risk of freezing and freezing in winter, and the structure and operation principle of the hydrant valve fixed to the hydrant body are complicated. Increasingly, the cost of manufacturing a fire hydrant is increased, and a sudden fire hydrant rising shock due to a high pressure of water due to a rapid distillation valve operation is generated, which exposes the risk of damage to the fire hydrant body.
