DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mainly used in a fountain facility for enjoying a water view, and in addition, a watering nozzle and a watering device used when water is diffused and spread over a wide area such as a fire fighting facility. It is about.

[0002]

2. Description of the Related Art A watering nozzle and a watering device of this kind are
In particular, the conventional ones used in fountains can show how high water can be spouted out, or how strongly they can attract the viewer's attention by devising the thickness and sharpness of the water column that is jetted upward Most of them have been developed with a focus on linear and planar fountain modeling.

[0003]

In the above-described conventional watering nozzle and watering apparatus, since the water spreads linearly and planarly, fire fighting equipment and the like in which a wide water diffusion range is desired. Not only can not be used,
Even when used as a fountain facility for waterscapes, the decorativeness and effect of the fountain modeling with a three-dimensional and dynamic feeling cannot be obtained. In addition, it is also possible to use three or more conventional watering nozzles that jet water linearly and planarly, and devise the watering direction and watering angle of these multiple nozzles to spray water three-dimensionally. However, in this case, a plurality of nozzles must be used, and a complicated support structure for supporting a plurality of nozzles with different watering directions and watering angles, and water is stably and lost to those nozzles. Special water supply equipment is also required to supply a small amount of water, and the whole sprinkler tends to be structurally very complicated and expensive.

[0004] The present invention has been made in view of the above circumstances, and can diffuse water three-dimensionally and widely with only a single nozzle, and can be particularly effectively used as a fountain facility for waterscapes. The main purpose is to provide a nozzle for watering that can also be used for firefighting equipment and other purposes. In addition to three-dimensional modeling, water that has a very dynamic It is an object of the present invention to provide a sprinkler capable of obtaining the shape of the water spray.

[0005]

In order to achieve the above object, a sprinkling nozzle according to the present invention has a slit formed along a streamline direction of water on a peripheral wall of a nozzle body having a dome-shaped tip. A plurality of slit-shaped openings are formed at intervals in the circumferential direction, and these slit-shaped openings have a length reaching the vicinity of the top of the dome-shaped tip portion. Is what you do.

According to the watering nozzle of the present invention having the above structure, the main flow of water supplied into the nozzle main body is formed on the peripheral wall of the nozzle main body so as to reach the vicinity of the top of the tip of the dome shape. At the same time, the water is discharged from the upper ends of the plurality of slit-shaped apertures vigorously outward diagonally upward, and at the same time, some of the water collides with the top of the dome-shaped tip, and the streamline direction It bounces in the opposite direction, hits the main flow of water flowing from the base end side of the nozzle body, is diffused in the circumferential direction, and is discharged horizontally and outward from a plurality of slit-shaped openings as a large vertical flow. Is done. As described above, the water is sufficiently diffused in the circumferential direction and the vertical direction of the nozzle body while spraying water over a wide area in a three-dimensional manner while suppressing the linear upward scattering of water, so that the water is used as a fountain facility for waterscapes. In this case, a three-dimensional and dynamic fountain formation can be obtained, and the decorativeness and effect of the fountain can be enhanced. In addition, it can be used as fire fighting equipment and the like because the range of watering is widened.

[0007] In particular, in the watering nozzle, the water supply base end portion of the nozzle body has a divergent shape, and the base portion of the divergent shape also has an elongated hole along the circumferential direction and water. When adopting a configuration in which a plurality of slit-shaped openings along the streamline direction are mixed and formed at intervals in the circumferential direction, a part of the water supplied to the nozzle body is divergent. Water is diffused more widely and three-dimensionally because it is also discharged diagonally upward from the plurality of elongated holes and slit-shaped holes formed at the end. It is possible to obtain a water spray molding with a more three-dimensional and dynamic feeling.

Further, in the watering device according to the present invention, a slit-shaped opening having a length reaching the vicinity of the top of the dome-shaped tip portion is provided on the peripheral wall of the nozzle body having a dome-shaped tip portion. Sprinkling nozzles in which a plurality of holes are formed at intervals in the circumferential direction are arranged in the water storage portion in a vertical posture with the dome-shaped tip portion of the nozzle body being the highest, and the sprinkling nozzle is At the lower end of the nozzle body, a water storage unit that can store water that is stored in the water storage unit and flows into the nozzle main body through the slit-shaped opening is connected. A compressible fluid supply device for discharging stored water by supplying a fluid from each slit-shaped opening of the watering nozzle is connected via an on-off control valve.

According to the watering apparatus of the present invention having the above-described structure, the water stored in the water reservoir flows into the nozzle body through the slit-shaped opening formed in the peripheral wall of the nozzle body. Stored in water storage. In such a state of storing water, when the on-off control valve is opened and the compressible fluid is supplied from the compressible fluid supply device into the water storage unit, the water in the water storage unit is rapidly sent to the watering nozzle. In this watering nozzle, three-dimensionally and actively shaped water is discharged like a volcanic eruption by being vigorously discharged and scattered from a plurality of slit-shaped openings formed in the nozzle body in the circumferential direction of the nozzle body. A figure will be obtained. Here, by changing the opening timing of the opening / closing control valve variously with time in relation to the amount of stored water in the water storage unit, the discharge form in the circumferential direction and the vertical direction of the nozzle body from the slit-shaped opening,
In other words, it is possible to make a great change in the temporal and spatial diffusion pattern of water, and when used as a fountain facility for waterscapes, it is necessary to give diversity to the size and shape of the three-dimensional and active fountain body. It is possible to remarkably enhance the decorativeness and effect of the fountain. In addition, it is possible to circulate and use the water in the water storage section, such as storing the water stored in the water storage section in the water storage section through the opening of the watering nozzle. This is unnecessary, and the overall structure of the sprinkler can be simplified, made compact, and reduced in cost.
