Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rising rotary water sprinkler for melting snow, mainly for removing snow from roofs of houses, surroundings of houses, station plazas, roads, etc. in areas with heavy snowfall.

Conventionally, in areas with heavy snowfall, methods for removing accumulated snow include, in addition to manual labor, heat ray road heating, hot water pipe broad heating, running water snow melting using groundwater, and snow melting by sprinkling water on snow with a rotary water sprinkler. There is.

From past experience, we know that each type has its own characteristics, advantages and disadvantages, but snow melting using a rotary water sprinkler extinguishes lightning in a short time and is economically inexpensive.

However, rotary water sprinklers have disadvantages such as exposing the water spraying head (if buried in snow, the swing arm etc. will be unable to rotate due to the resistance of the snow, and spraying water from above the snow may cause melted snow to freeze). It had a

The present invention is a rising rotary water sprinkler for snow melting that eliminates these drawbacks. Next, this will be explained with reference to the embodiment shown in the drawings. 1 is a water sprinkler head box, and the head box 1 has drainage holes 2. , 2 are provided.

3 is a lid that covers the upper part of the head box 1, and a backing 5 that slides the upper end of the water sprinkling head body 4 at the bottom of the drawer 3.
It is rotatably provided through.

Reference numeral 6 denotes a water conduit pipe provided in the upper part of the main body of the water spraying head, and head nozzles 9 and 10 connected to the water conduit pipe and having a plurality of diagonally upward spout lowers and a large number of lateral spout ports 8 are introduced into the water conduit pipe 6. Adjustment screw part 11 and lock nut 12 at the top of the water pipe
13 are stacked on top of each other and protrude from the top of the lid 3 via a slide backing 5'.

Therefore, the head nozzle portion A formed by the head nozzle 910
water can be sprayed with the lid covering the head box as shown by the solid line, but if the head body 4 moves upward and rotates due to water conduction pressure as shown by the dotted line,
The head nozzles 9 and 10 move upward and rotate together with the head body 4, and water is sprayed from the jet lowers 8 of the head nozzles 9 and 10.

Then, quickly remove the snow on the lid 3 (when trying to melt the snow,
Loosen the opening nut 12 and rotate the head nozzle 9 to spray water from the entire circumference of the overlapping part 13 with an appropriate gap so that it can melt the snow on the lid in cooperation with the horizontal spout 8. This is what I did.

In addition, 14 is the main nozzle of the water spray head, 15 is the side nozzle of the head body, and 16 is a swing arm loosely attached to the arm shaft 17 which also serves as a water flow pipe. Of course, in this case, if the water jet from the side nozzle is applied to the impulse arm a, the swing arm will rotate due to the water force, and the receiver of the head body will be attached to the frame 18.18'. The swing arms 16, 16 apply an impact to rotate the head body, then the spring 20 returns to its original position, and this process is repeated to rotate the head body.

19 is a buffer spring, 21 is a sliding cylinder, 22 is a guide cylinder, 23 is a head box support pipe that also serves as a water pipe, 2
4 is a return spring, 25 is a cap nut, 26 is a lock nut,
27 indicates a slide backing.

In the present invention, which is configured in a diagonal manner, in areas with heavy snowfall, for example, the water sprayer head box 1, which stores the water spray head body etc. in the head box, is installed underground in a station plaza, a road, etc., and the lid 3 is placed on the ground. If the sprinkler head box 1 is aligned with the surface of the house or installed around the house or on the roof of the house, the sprinkler head main body 4 will initially react to the snow on the cover 3 of the sprinkler head box as shown by the solid line. head box 1
Water is sprayed from the main nozzle and side nozzle inside the lid 3, and the head nozzle 910 on the lid 3 also sprays water above and around the spout lower 8 at that position, gradually melting the snow on the top of the lid and around it. Then, a cavity is created in this part, and then the main nozzle 14 and side nozzle 15 of the water spray head body 4 are naturally raised into the cavity by the water guiding pressure as shown by the dotted line, and the head nozzle 9 is rotated.
10, water is discharged together with the lower head nozzle 10 to further melt snow on the ground surface, making snow removal work extremely easy.Furthermore, by loosening the lock nut 12 and rotating the upper head nozzle 9, the overlapping part 13 with the lower head nozzle 10 is removed. By sprinkling water with gaps in between, the snow on the head box lid will flow down more quickly, allowing the water spray head to quickly melt the snow. If you leave it there,
Avoid causing accidents where watering is not possible (it has a remarkable effect on snow removal).

Of course, if the water supply is stopped, the head body and lid will return to their original state.

Claims (1)

[Claims] 1 At the lower part of the lid 3 which covers the upper part of the water sprayer head box 1, the upper end of the water spray head main body 4 inside the head box is rotatably provided via a slide backing 5, and the inside of the water spray head main body 4 is rotatably provided. A head nozzle part A in which upper and lower head nozzles 910 having upper and lower head nozzles 910 having an ejection lower 8 communicating with the water conduit pipe 6 are arranged is provided on the upper part of the lid 3 via a slide backing 5', This rising rotary water sprinkler for snow melting is characterized in that a head nozzle part A is provided on a water conduit pipe 6 so as to be adjustable so as to provide an appropriate gap.
