Description
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.
SUMMARY OF THE INVENTION The present invention has been accomplished to solve the above problems, and it is an object of the present invention to provide a hose having a plurality of exhaust holes formed at regular intervals, a coupler installed at both ends of the hose, And the angle of the hose is adjusted by the nozzle so that the direction of spraying of the fire water can be easily changed.
According to an aspect of the present invention,
A hose having a plurality of exhaust holes formed in its longitudinal direction, first and second couplers coupled to both ends of the hose, and an angle adjusting unit coupled to the first and second couplers, respectively.
The first coupler may have a first coupling hole formed on the outer circumferential surface thereof and a second coupling hole formed on the inner circumferential surface of the second coupling coupler.
The angle adjusting unit may include a support ring coupled to the outer sides of the first and second couplers and an angle adjusting member fixedly coupled to the first and second couplers through the through holes of the support ring .
Further, a support leg is provided under the support ring.
The angle adjusting member may include a guide member coupled to the through-hole of the support ring, an adjusting member having a fixing shaft coupled to the inside of the guide member, and an elastic member provided between the guide member and the adjusting member .
The outer circumferential surface of the first and second couplers is formed with a moving groove for moving the fixing shaft of the adjusting member in the circumferential direction, and a plurality of fixing grooves are formed on the inner side of the moving groove at regular intervals.
In addition, a cap is coupled to the first coupling port of the first coupler.
According to the present invention, there are provided a hose having a plurality of exhaust holes formed at regular intervals, a coupler installed at both ends of the hose, and an angle adjusting unit coupled to the coupler, so that the angle of the hose can be adjusted by the angle adjusting unit, Can be changed.
