Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a snow-melting water nozzle for dissolving snow by spraying underground water, seawater, etc. onto a road surface.

[Prior Art] As a conventional water spray nozzle of this kind, one in which water from a water pipe is injected into a cavity and then sprayed onto the road surface from four water sprinkling ports is known from Japanese Utility Model Application Publication No. 50-13209. It is being In this system, water is sprayed in a water line shape from four water sprinkling ports, with the amount of water being regulated by the vertical movement of a water volume adjustment knob provided at the center of the cavity.

[Problems to be solved by the invention] In the above-mentioned conventional technology, the amount of watering can be adjusted using the water amount adjusting knob, but there is a limit to the flying distance of watering and the direction of watering is limited to four directions. Therefore, there was a problem of low snow removal efficiency. Also,
Sand and other substances tend to accumulate in the cavities into which water is injected from the water pipes, and this sand and other substances impede water spraying, further reducing the efficiency of snow removal.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a water spray nozzle for snow removal that can effectively melt snow over a wide distance and in a wide direction without sand or the like accumulating in the cavity and preventing water spraying.

[Means for Solving the Problems] The present invention includes an inner nozzle body having a tapered peripheral surface, and an outer nozzle body fixed to the inner nozzle body, and a water supply hole provided in the inner nozzle body. and a cavity formed by the tapered circumferential surface and the circumferential surface of the outer nozzle body are communicated with each other by water control holes that are inclined in vertical and horizontal directions, and the upper end of the cavity is connected to the tapered circumferential surface. The water spout is formed into an annular planar shape with a diameter smaller on the outside than on the inside.

[Function] The water flow from the water supply hole flows into the cavity as a swirling flow through the water control hole that slopes downward and laterally.
The sand inside this cavity swirls together with the water flow, and the water flow swirling inside the cavity is rapidly condensed along with the sand, etc. along the tapered peripheral surface and the water spout, creating a water film all around 360 degrees. water is sprinkled on the ground.

[Example] Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

In FIGS. 1 to 4, reference numeral 1 denotes an inner nozzle body connected to a water pipe 3 via a gasket 2, and has a substantially inverted conical portion 4 formed at its upper portion. Reference numeral 5 denotes an outer nozzle body fixed by a screw portion 6 of the inner nozzle body 1, and a cavity 9 is formed by the tapered circumferential surface 7 of the substantially inverted conical portion 4 and the vertical circumferential surface 8 of the outer nozzle body 5.
is formed. Reference numeral 10 denotes a water supply hole installed vertically in the center of the inner nozzle body 1, and communicates with the cavity 9 through three water control holes 11 formed at the lower part of the inverted conical portion 4. The water control hole 11 slopes downward as it moves outward as shown in FIG. 1, and also slopes counterclockwise as it moves outward when viewed from a plane as shown in FIG. Reference numeral 12 is a knob for adjusting the amount of water that is screwed onto the upper part of the water supply hole 10 and can be adjusted with a screwdriver or the like. Reference numeral 13 denotes a flange that projects from the inner nozzle body 1 so as to come into contact with the bottom surface of the cavity 9. Reference numeral 14 denotes a water sprinkling port formed at the upper end of the cavity 9 so as to be continuous with the tapered circumferential surface 7 and in the same inclined state, and is continuously formed in an annular shape when viewed from a plane.
In this case, the water sprinkling port 14 is formed by the tapered circumferential surface 7 of the inner nozzle body 1 and the tapered circumferential surface 8A formed at the upper end of the circumferential surface 8 of the outer nozzle body 5 opposing thereto. By changing the angle of inclination between the water spout 7 and the tapered circumferential surface 8A, the water spout 14 is formed into an annular shape whose diameter gradually decreases from the inside to the outside. 15 is a groove for an attachment/detachment tool formed on the upper surface of the inner nozzle body 1. The water flow sent through the water pipe 3 is pressure regulated from the water supply hole 10 with a water volume adjustment knob 12, and then injected into the cavity 9 through the water control hole 11, and is sprayed from the water sprinkling port 14. In this case cavity 9
The water inside is condensed by an annular water sprinkling port 14 whose diameter gradually becomes smaller toward the outside, and is sprayed over a wide area with a sufficient flying distance to form a water film over the entire 360° circumference. Further, the water flow becomes a swirling flow through the water control holes 11 that are inclined downward and laterally, and flows into the cavity 9, so that sand and the like in the cavity 9 swirl along with the water flow and follow the tapered circumferential surface 7. Water is sprayed from the sprinkling port 14 along with sand and the like while being squeezed.

In this way, in the above embodiment, the water supply hole 10
The water flow from the water supply hole 10 becomes a swirling flow through the water control hole 11 which is inclined downward and laterally by communicating the water control hole 11 which is inclined vertically and horizontally with the cavity 9. flows into the cavity 9, and this cavity 9
The sand inside swirls together with the water flow, and at the upper end of the cavity 9, continuous to the tapered peripheral surface 7, a water sprinkling port 14 whose diameter is smaller on the outside than on the inside is formed in an annular planar shape. As a result, the water swirling inside the cavity 9 is rapidly condensed along with sand, etc. along the tapered circumferential surface 7 and the water sprinkling port 14, and is sprayed in a water film over the entire 360° circumference, and is sprayed all around the circumference with a sufficient flying distance. Snow is effectively melted by spraying water over a wide area.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made within the scope of the gist of the present invention. For example, as shown in FIG.
A may be fixed, and the shape and structure of the inner and outer nozzle bodies may be modified as appropriate. Alternatively, it may be fixed by fitting the threaded portion elsewhere. Further, the shapes and structures of the cavity, the water control holes, and the water volume adjustment section may be modified as appropriate, and the number and inclination of the water control holes may also be changed as appropriate. Further, the water spout may have an annular planar shape, and is not limited to a circular shape, but may be rectangular or the like. Further, the structure in which the diameter becomes smaller toward the outside may be selected as appropriate; for example, as shown in FIG.
Alternatively, as shown in FIG. 6, the water spout 14B may be formed by making the outside diameter smaller than the right side by the stepped portion 16.
In short, any water spout that has a smaller diameter on the outside than on the inside will suffice.

[Effects of the invention] The present invention includes an inner nozzle body having a tapered peripheral surface, and an outer nozzle body fixed to the inner nozzle body, and a water supply hole provided in the inner nozzle body and a water supply hole provided in the inner nozzle body, The cavity formed by the circumferential surface and the circumferential surface of the outer nozzle body is communicated by a water control hole that slopes in the vertical and horizontal directions, and the upper end of the cavity is connected to the tapered circumferential surface from the inside. It is a water extinguisher that has an annular planar shape with a water sprinkling port that has a smaller diameter on the outside, and has a wide scattering distance and water spraying direction without interfering with sand or other particles accumulating in the cavity and effectively melting snow. We can provide snow sprinkler nozzles.
