Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a water spray nozzle for dissolving snow by spraying underground water, river water, etc. onto roads, parking lots, etc.

[Technical background and problems of the invention]

Conventionally, water nozzles, which spray groundwater sent through a water pipe onto the ground surface from a water spout, have been widely used for snow removal during the winter.

However, with conventional water nozzles, the water spout becomes clogged during seasons other than winter when water is not sprinkled, and as a result, the water spout has to be restored at the beginning of the winter season. In other words, sand and pebbles on the road clog the water spout when water is not being sprinkled;
The pebbles are pushed in by the vehicle's tires, and as a result, the blockage cannot be cleared by poking it with a wire. For this reason, in order to restore the water sprinkling ports, they are drilled one by one using an electric drill, an extremely complicated process that is repeated every year.

For example, a conventional water spout is proposed by the same applicant in Japanese Patent Publication No. 51-12336 as shown in FIG.
The end of the nozzle body 3 is connected to the water supply hole 4 of the nozzle body 3. The nozzle body 3 has a cavity 6 formed above the water supply hole 4 via a partition wall 5, and further has a plurality of water sprinkling holes 7 communicating with the cavity 6 and the outside, and also has a plurality of water spray holes 7 communicating with the outside. A pressure regulating valve 8 is provided at The pressure regulating valve 8 includes a pressure regulating valve main body 8a communicating the water supply hole 4 and the cavity 6, and a spindle 8b screwed onto the pressure regulating valve main body 8a.

Furthermore, a rectifier pipe 9 is disposed outside the water flow control hole 8c of the pressure regulating valve 8, and the water sent from the water pipe 1 passes through the water flow hole 4, the water flow control hole 8c, the cavity 6, and the water sprinkling port 7. It is something that is discharged through the body.

However, since the water sprinkling port 7 is always open, it becomes clogged with sand, pebbles, etc.

As a means to solve such problems, it is conceivable to break-fit a cover that covers the upper surface of the nozzle body 3 together with the water sprinkling port 7 of the water sprinkling nozzle.

However, in such a cover type, since it is not integrated with the water spray nozzle main body, there is a risk of it coming off when a vehicle passes by.

Furthermore, it is also possible to install a plug at the water sprinkling port of the water nozzle, but in such a plug method,
One water sprinkling nozzle has a plurality of water sprinkling ports 7, generally four water sprinkling ports 7, which has the disadvantage of low work efficiency. It is conceivable to provide a rotatable outer plate on the outside of the outer plate, and to form a valve hole in the nozzle hole in the outer plate so that the nozzle hole and the valve hole match to spray water. The disadvantage is that the nozzle hole faces upward, making it impossible to spray water around the area.

[Purpose of invention]

The present invention has been made in consideration of the above circumstances, and aims to provide a water sprinkling nozzle that has a water sprinkling port that can be opened and closed and that can be easily switched.

[Summary of the idea]

This invention has a water supply hole in the lower part of the water supply nozzle body, a hollow part connected above the water supply hole, and a water supply hole that communicates this cavity with the outside. In the nozzle, the water sprinkling holes are formed diagonally upward on the outside, and a plurality of the water sprinkling holes are provided at intervals concentrically with the water sprinkling nozzle main body, and the water sprinkling holes can be opposed to the water sprinkling ports on the outside of the water sprinkling ports. A water stop wall is provided concentrically with the nozzle body at intervals, and the water sprinkling hole or the water stop wall is rotatably provided around the axis of the nozzle body so that the water sprinkling port can be opened and closed.
