Description

A folding type fire demand water discharge device for fire hydrant

The present invention relates to a folding outlet for fire extinguishing for underground burial, and more specifically, by embedding a fire hydrant to prevent freezing in the winter and block exposure from the ground, so as to improve the usability of the surrounding space and induce safety. In addition, the present invention relates to a folding outlet for extinguishing underground burial, which allows the outlet to be exposed to the ground by folding, thereby greatly improving the ease and convenience of extinguishing a fire.

In general, fire hydrants are classified into indoor fire hydrants installed inside buildings and outdoor fire hydrants installed outside buildings.

Among them, the outdoor fire hydrant is a disaster prevention facility that supplies fire-fighting water for fire extinguishing, and must be constructed in a durable structure and method so that it can be maintained, repaired and used for a long time after being installed. It should not be exposed to dangers such as damage, breakage, freezing of fire extinguishing water, etc., and should be kept available at all times.

These outdoor fire hydrants are divided into underground type outdoor fire hydrants buried underground and ground type outdoor fire hydrants exposed to the ground, and underground type fire hydrants are equipped with manholes and fire hydrants installed in the manholes, so that they can cope with winter freezing to some extent. On the other hand, since the fire hydrant is buried underground, it is difficult to connect a fire hose to a fire hydrant installed inside a manhole in a narrow space in the event of a fire, and it is difficult to maintain and maintain a fire hydrant.

In addition, the ground fire hydrant is easy to connect fire hoses, but because the fire hydrant is exposed to the ground, it is very vulnerable to winter freezing, so when a fire occurs, the fire hydrant freezes, making fire extinguishing difficult and extinguishing. There is a problem of being exposed to a safety accident due to a collision of pedestrians or vehicles by a fire hydrant, and the use of the ground space occupied by the fire hydrant exposed to the ground is greatly reduced, as well as when a fire occurs due to corrosion of the fire hydrant exposed to the ground. There is a problem that the hydrant operation does not work properly.

Accordingly, an underground fire hydrant has been devised to allow the fire hydrant to move up and down.

As an example, there is a rotary fire hydrant, which is a registered patent No. 10-0972144, which is installed inside a manhole having a space inside and a manhole cover is installed on the top of the manhole, buried below the manhole. A main buried pipe to move the fire extinguishing water, a main valve installed at the main buried pipe to supply the fire extinguishing water, and a direction changing connector for switching the flow of the fire extinguishing water connected to one end of the main buried pipe, A branch pipe having a flow path formed inside is formed, and a discharge pipe is rotatably installed in a space formed between the branch pipes, and at the other end, a connection pipe installed to be connected to a direction changing connector and a fire hose connected to the upper portion are connected. A hose connection part is provided, and a pivot tube installed in the connection tube is integrally formed at the bottom, and a cap member is provided outside the rotation tube. A safety valve consisting of a discharge pipe configured by a connection, a head portion installed at an end of a rod portion connected to the cap member to open and close the flow path of the connection pipe, an elastic member for restoring the safety valve, and the direction changing connection pipe. It is equipped with a drain valve installed at the bottom to rotate the discharge pipe upright so that it appears and exits from the manhole.

However, such a conventional technique has a problem in that the configuration is complicated, and the installation is burdensome.

As another example, a lift-type fire hydrant assembly, which is a registered patent No. 10-0949366, has been devised, which is a water pipe to which fire-fighting water is supplied according to opening and closing of a water discharge valve buried underground, an elbow pipe connected to the water pipe, and the elbow pipe A fixed pipe connected to the fixed pipe, a lifting pipe coupled to the fixed pipe and driven to the ground, and a guide block coupled to the inner surface of the fixed pipe at the lower end, and a sealing plate coupled to the upper end of the fixed pipe to prevent departure of the lift pipe And, the head block having a hose connector connected to the upper end of the hoisting pipe is connected to the fire hose, and the valve means for opening and closing the lower end of the hoisting pipe, and the air between the fixed pipe and the hoisting pipe to exhaust or suck It is provided as an air valve to open and close, and when the distillation valve is opened, the lower end of the elevating pipe is closed by the valve means The w is a steel tube by the rising pressure of the fire extinguishing can be supplied through the water pipe in the state and to be exposed to the surface so as to rapidly connect the fire hose in case of fire hydrants.

However, such a conventional technology has a complicated configuration, and thus has a burden on the cost of installation, and there is a inconvenience in that the fire hydrant must be lifted by opening the distillation valve during maintenance work of the fire hydrant.
