Description

Water curtain fire hose {fire hose}

The present invention relates to a water curtain fire hose, and more particularly, to a water curtain fire hose, which comprises a hose having a plurality of discharge holes formed at regular intervals, a coupler installed at both ends of the hose and an angle adjusting unit coupled to the coupler, To a water curtain fire hose capable of changing an injection direction of fire water easily by adjusting the angle.

Generally, when a fire occurs, a powder fire extinguisher is used to inject the fire extinguishing agent filled in the fire extinguishing agent into the fire source, or after connecting the hose to the fire extinguisher, the high pressure water supplied from the fire extinguisher is sprayed directly to the fire source to suppress the fire.

In recent years, thanks to the development of technology, it has been improved so that fire can be extinguished through an automatic fire extinguishing system such as sprinkler which is detected so that water is sprayed from a ceiling surface of a building or the like.

On the other hand, when a fire occurs, fire or water is usually used to evolve the fire. Sprinklers or water spray devices are used as equipment for this purpose, but the usual method of evolution using water or a foam solution is limited to limited range of spraying It is unsuitable for extinguishing large-sized buildings such as fire or forest fire, and it is difficult to evolve a wide range of oil and gas fires.

In addition, since the fire fighting equipment is designed to spray water in a simple straight shape, the spraying range is limited and it is not suitable as a device for preventing the fireball from penetrating into the building or preventing it from spreading to the outside.

As a conventional technique for solving such a problem, Korean Utility Model No. 20-2009-0006558 discloses a fire prevention valve structure for forming a water film for protecting a temple cultural property. The technical structure thereof is combined with an external hose, And a fan-shaped discharge port integrally connected to the hose coupling port; Wherein the fan-shaped discharge port has a diffusion area diffused at a predetermined angle with a transfer area for transferring water therein, and a rounded discharge hole in which fine holes are perforated in the shape of a straight line at the end, wherein the discharge hole has a width Is formed to be the longest and to be shortened toward the edge.

However, in the conventional art, the rotation angle of each discharge port must be adjusted in order to adjust the spray angle, which is cumbersome and takes a lot of time.
