BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water spray nozzle that sprays water in a predetermined range.

[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
For example, as a water sprinkling nozzle that sprinkles water from a nozzle in a fan shape in a desired predetermined range, a thin water sprinkling nozzle hole 21 having a predetermined width is formed on the peripheral surface of a cylindrical water sprinkling nozzle tube 20 as shown in FIG. Some spray water from the nozzle hole 21 in a fan shape. However, such a conventional water spray nozzle can spray water in a fan shape by the opening range of the water spray nozzle hole 21 with a narrow water spray direction and the water pressure, but it does not fly far and does not become a stable fan water spray and stabilizes the desired range. It is difficult to keep watering well.

Further, since the water spray nozzle holes 21 are simply opened in the thin wall-shaped water spray nozzle tubes 20, water spray nozzle holes 21 having different water spray angles can be formed side by side on one water spray nozzle tube 20. is not.

According to the present invention, water can be sprayed in a predetermined range as needed, and the spray can be opened thinly in a fan shape and can fly far, and can spray water in a predetermined range stably and accurately without wasting the amount of water, and the spraying distance is different and the spraying distance is different. It is an object of the present invention to provide an excellent water sprinkling nozzle in which water spouting nozzle holes having different shapes can be formed side by side.

[0005]

The gist of the present invention will be described with reference to the accompanying drawings.

A thick nozzle forming portion 2 is formed at the tip of the nozzle base 1.
The outer surface of the thick nozzle forming portion 2 is formed into a curved surface 3, and a nozzle groove 4 having a predetermined width is formed in the curved surface 3 in a direction in which the groove opening outer surface is curved. The present invention relates to a water sprinkling nozzle characterized in that a water passage hole 5 is communicated with a bottom portion.

Further, the water passage hole 5 is made to communicate with the center of the bottom of the nozzle groove 4, and a water passage guide recess is formed on the inner surface of the nozzle groove 4 from the water passage hole 5 toward the outer surface of the groove opening of the nozzle groove 4. The sprinkling nozzle according to claim 1, wherein the sprinkler 6 is formed. In addition, the nozzle forming portion 2
The water spray nozzle according to claim 1, wherein a plurality of nozzle grooves 4 having different surface directions of the groove inner surface that determines the water spray angle are formed on the curved surface 3.

[0008]

The water that has passed through the water passage hole 5 is sprayed outward from the bottom surface of the nozzle groove 4 along the inner surface of the nozzle groove 4 and from the outer surface of the groove opening.

Therefore, the water spouting from the water passage hole 5 is not simply spouted from the nozzle hole, but once the direction of water spouting is regulated on the inner surface of the nozzle groove 4 and spouting with a predetermined sprinkling pressure, which is the case in the conventional example. On the other hand, the nozzle grooves 4 are regulated by the narrow groove widths and the inner surfaces facing each other with a predetermined depth, and water is sprinkled to a long distance, so that the desired range can be sprinkled accurately.

Further, if the bottom surface of the nozzle groove 4 is made flat, the outer surface of the nozzle opening of the nozzle groove 4 is curved, so that water is sprayed in a fan shape by a predetermined angle corresponding to the lateral width (predetermined width) of the nozzle groove 4. It will be.

Further, the water passage hole 5 is made to communicate with the center of the bottom of the nozzle groove 4, and a water passage guide groove is formed on the inner surface of the nozzle groove 4 from the water passage hole 5 toward the outer surface of the groove opening of the nozzle groove 4. If 6 is formed, the water in the other water spray directions will also fly far, as if being drawn by the line water spray along the water guide groove 6. Further, as shown in FIG. 6 in which broken lines show how the water is sprayed when the guide recesses 6 are not formed, the water guide recesses 6 are formed in the water passage direction which goes straight from the water passage hole 5 which is the most difficult to fly. The water sprinkling distance in this direction extends, and it is possible to sprinkle a fan-shaped water with a substantially uniform amount of water to a long distance.

Further, by forming a plurality of nozzle grooves 4 on the curved surface 3 of the nozzle forming portion 2 in which the surface directions of the groove inner surface for determining the water spray angle are different, it is possible to spray water from one spray nozzle at different angles. Therefore, the nozzle groove 4 can spray water at a distant predetermined range, and the other nozzle groove 4 can spray near a predetermined range at the same time.

EXAMPLE In this example, a joint hole 7 is formed in the base portion of the nozzle base 1, the water passage hole 5 is formed from the joint hole 7 toward the tip, and the joint hole 7 is communicated so as to intersect with the water passage hole 5. A water amount adjusting rod 9 having a hole 8 is rotatably installed.

Accordingly, the joint hole 7 and the water passage pipe 10 are communicated with each other through the joint pipe 11 or the like, and the water that is passed from the water passage pipe 10 is passed through the joint hole 7 and the communication hole 8 of the water amount adjusting rod 9. It has a structure in which water is passed through the water passage hole 5 and is sprinkled outward from the water passage hole 5 through the nozzle groove 4.

By rotating and adjusting the water amount adjusting rod 9, the degree of communication between the communication hole 8 and the water hole 5 is adjusted so that the water amount (water pressure) can be adjusted.

In this embodiment, a solid nozzle forming portion 2 protruding in a thick wall is formed at the tip of the nozzle base 1, and the nozzle forming portion 2 is formed in a curved chevron cross section.
The outer surface of the tip of the is formed into the curved surface 3.

A nozzle groove 4 having a predetermined width and a narrow groove width is formed on the outer surface of the nozzle forming portion 2 at a predetermined angle.
The inner surface of the nozzle groove 4 is curved so that the inner surfaces of the nozzle groove 4 facing each other are flat, and the bottom of the nozzle groove 4 is a flat bottom surface. Is forming.

The water passage hole 5 is formed so as to communicate with the central portion of the flat bottom surface of the nozzle groove 4.

In the present embodiment, when the nozzle groove 4 is cut out, a small circular hole is first formed from the top of the curved surface 3 toward the water passage hole 5 inside, and the small circular hole is used as a foothold. The nozzle groove 4 is formed by cutting it to the left and right at a predetermined width, the water passage hole 5 is made to communicate with the center of the bottom portion of the nozzle groove 4, and the small circular hole is formed on the inner surface of the nozzle groove 4 after this small hole is formed. A linear water guide groove 6 extending from the water hole 5 toward the groove opening screen of the nozzle groove 4 is formed oppositely.

Further, in this embodiment, two water passage holes 5 are formed from the joint hole 7, and the nozzle grooves 4 communicating with the water passage holes 5 are formed in the nozzle forming portion 2 in parallel in the vertical direction.

The upper nozzle groove 4 is formed by cutting out substantially horizontally when the nozzle forming portion 2 is directed to the front so that the inner surface of the nozzle groove 4 becomes a horizontal surface, whereas the lower nozzle groove 4 is formed. 4 has a notch formed from the lower side to the slightly upper side,
The inner surface of the nozzle groove 4 is configured to be inclined downward toward the groove opening side.

Therefore, in this embodiment, the upper nozzle groove 4 flies farther, and the lower nozzle groove 4 sprinkles water closer to the lower portion.

Therefore, for example, if it is installed under the platform 12 of the station as shown in FIG. 4, it is possible to sprinkle water over a predetermined area of the railroad track to remove snow. In this case, the rail on the far side of the upper nozzle groove 4 is used. Therefore, it is possible to sprinkle water in a predetermined range and reliably spray water in a predetermined range of the rail on the side closer to the lower nozzle groove 4.

By arranging the main nozzles at predetermined intervals in this way, only the rails of the railroad track can be surely erased without waste.

Further, as to the effect of the water guide groove 6, when sprinkling a rather large amount of water, if there is no water guide groove 6, as shown by the broken line in FIG.
Inevitably, the central part where the water passage hole 5 is provided, that is, the water pressure in the straight direction that sprinkles water directly from the water passage hole 5 is weak and it is difficult to fly far, but this water guide concave groove 6 allows water to be sprinkled well in this direction. Since it is easy to fly, it is possible to perform a neat fan-shaped water spray without weakening the central portion of the water spray, and it is possible to achieve a good fan-shaped water spray with a substantially uniform water spray amount in all directions of a predetermined width.

Further, the water sprinkling in the direction along the water guide groove 6 in the central portion has a great momentum, and the water spouting in the other direction also pulls the water sprinkling in other directions, resulting in a better flight as a whole. Therefore, it is possible to design a structure in which the water sprinkling distance can be maintained for a very long time and only a predetermined range can be surely sprinkled.

In this embodiment, the thick nozzle forming portion 2 having a substantially semicircular cross section is formed so as to bulge on the front surface. However, a small-diameter passage is formed inside a thick pipe-like shape, for example, a solid cylinder. The water holes may be formed to form the nozzle forming portion 2 on the entire circumference.

[0028]

Since the present invention is constructed as described above, it is possible to satisfactorily perform stable fan-shaped water sprinkling capable of surely sprinkling a predetermined range, and the water sprinkling distance is far superior to the conventional example. It becomes a sprinkling nozzle.
