Abstract

A spray structure for firefighting has a firefighting water gun and a stopper. A U-shaped positioning block is protruded from the lower half of the arc-shaped profile of the water outlet end of the firefighting water gun toward the water outlet direction. The stopper is fixed to the position block, so that there is a distance between the stopper and the firefighting water gun. When the water contacts the stopper, the stopper forms a barrier, so that the water is sprayed outward along the surface of the stopper to form a fine water mist to form a water wall.

Description

Fire sprinkler structure

This work is about a water spray structure for fire protection, especially a water spray structure that can generate a water wall.

When a fire occurs, a large amount of heat energy is released by the combustion of the material and absorbed by the air in the fire site, resulting in a high temperature environment accompanied by a large amount of smoke. If the temperature is above 1,000 degrees, the temperature of the surrounding environment will continue to heat up due to the continuous burning of the fire site. Even if there are trained firefighters or the public, staying in the high temperature environment of the fire site for a long time will still cause harm to the human body. Therefore, in addition to putting out the fire at the fire site as soon as possible, it is also necessary to quickly reduce the temperature of the surrounding environment of the fire site to prevent firefighters from harming the human body due to the ambient temperature in the process of performing duties. Therefore, this design can also allow the water curtain wall to absorb air and convection. Heat to avoid extended burning and properly block smoke and convective heat.

In addition, firefighters will use a straight jet of water to form a water wall-like effect to prevent the fire from spreading to the houses around the fire site and reduce the ambient temperature around the fire site.

Based on the above deficiencies, the purpose of this creation is to provide a water spray structure for fire protection that can generate a water wall.

According to the purpose of the present creation, a water spray structure for fire fighting is provided, which has a fire water gun and a stopper. A water outlet end face of the fire water gun is protruded with a positioning block toward the water outlet direction, wherein the cross-sectional profile of the water outlet end face is The cross-sectional profile of the positioning block is U-shaped, and is protruded from the lower half of the arc-shaped profile of the water outlet end face. The stopper is fixed to the positioning block, so that the stopper and the water outlet The end faces are spaced apart by a distance for the flow of water to pass therethrough.

Wherein, the cross-sectional area of the stopper is larger than the cross-sectional area of the water outlet.

The positioning block is provided with a plurality of positioning holes, the stopper has a positioning structure, and the positioning structure has a plurality of perforations and a plurality of supporting ribs corresponding to the positioning holes, and a positioning element is simultaneously penetrated through the these positioning holes. The through holes and the positioning holes make the stopper fixed to the positioning block.

Preferably, the stopper is rectangular, triangular or sector-shaped.

Preferably, the fire water gun has at least one support foot.

In order to clearly illustrate the specific implementation, structure and achieved effects of this creation, the following examples are provided and described in conjunction with the drawings:

Please refer to FIG. 1 , which shows a fire-fighting water spray structure, which has a fire-fighting water gun 10 and a stopper 20 . A water outlet end of the fire-fighting water gun 10 is protruded with a positioning block 11 toward the water outlet direction. The positioning block 11 is provided with A plurality of positioning holes 111, the stopper 20 has a positioning structure 21, the positioning structure 21 includes a plurality of through holes 21a corresponding to the positioning holes 111 and a plurality of support ribs 21b, the support ribs 21b are used to strengthen the Equivalent to the structural strength of the through holes 21 a, a positioning element 23 is inserted through the through holes 21 a and the positioning holes 111 at the same time, so that the stopper 20 is fixed to the positioning block 11 . In this embodiment, the positioning hole 111 is a screw hole, and the positioning element 23 is a bolt. When the stopper 20 is fixed to the positioning block 11, the threaded portion of the bolt is screwed into the screw hole, and the nut portion of the bolt is connected to the through hole. 21a is contoured for a tight fit.

In this embodiment, the cross-sectional contour of the water outlet end surface is circular, and the cross-sectional contour of the positioning block 11 is U-shaped, and is protruded from the lower half of the arc-shaped contour of the water outlet end surface (ie protruding at the lower semicircle of the water outlet end face), at this time, a part of the stopper 20 is fixed to the positioning block 11, and other parts of the stopper 20 form a distance from the water outlet end face, the stopper The space between 20 and the water outlet end face is passed by the water flow. When the water flow contacts the stopper 20, the stopper 20 forms a barrier, so that the water flow is sprayed outward along the surface of the stopper 20 to form many fine water mists. Form a water wall.

In this embodiment, the stopper 20 is fan-shaped, and the cross-sectional area of the stopper 20 is larger than the cross-sectional area of the water outlet. Therefore, when the area of the stopper 20 fixed to the positioning block 11 is fixed, the larger the cross-sectional area of the stopper 20 is, the greater the range of the water wall formed. In other aspects, the stopper 20 may be, but not limited to, rectangular, triangular, or other geometric shapes.

In this embodiment, the fire-fighting water gun 10 has a support foot 12. When the firefighters are performing their duties, they can place the fire-fighting water gun 10 on the ground around the building on fire, and use the fire-fighting water spray structure of the present invention. , to form a protective water wall around the building on fire. When the water mist is sprayed on the surface of the burning object, the small water mist droplets form a thermal barrier to reduce the radiant heat of the fire source, reduce the temperature of the fire field, and prevent the fire from expanding or extending to the end. burning items.
