Abstract

PURPOSE: To provide the subject device with an expression function to gather the water columns and water lumps injected into the air to a visual point and an expression function to gather the visual point to a water surface as well. CONSTITUTION: Plural swivel joints 6 are mounted longitudinally at prescribed pitches in communication with a header pipe 3 to which high-pressure water is supplied from a pump 1. Fountain nozzles 10 and oscillation vanes 11A, 11B, 11C are mounted at the respective movable side members 6A of these swivel joints 6. The injection nozzles which inject the high-pressure water are positioned to correspond to these oscillation vanes 11A, 11B, 11C. The injection nozzles and the header pipe 3 are allowed to communicate by a water flow pipe 13. The injection water pressures to the oscillation vanes 11A, 11B, 11C are controlled by adjusting the opening angle of a control valve 14 interposed in this water flow pipe 13, by which the force against springs 15 is changed to vary the elevation angles of the fountain nozzles 10 and the positions where the water columns and water lumps arrive at the water.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water painting fountain device which expresses various paintings and figures on a water surface seen on a campus by utilizing ripples generated on the water surface by the fall of a fountain.

[0002]

2. Description of the Related Art A conventional fountain device is designed for the purpose of concentrating a viewpoint on a water column or a water mass which is intermittently or continuously jetted into the air from one or a plurality of fountain nozzles. No consideration has been given to the point of view of the ripples generated on the surface of the water.

Therefore, while focusing on the water column or water mass that is intermittently or continuously jetted into the air from the fountain nozzle, various paintings and figures were seen on the campus due to the ripples generated on the water surface by the fall of the fountain. By expressing it on the surface of the water that was taken up, we devised to collect viewpoints on the surface of the water,
We have completed a water painting fountain device with increased expressive functions.

[0004]

The problem to be solved is that it has only an expression function of concentrating the viewpoint on a water column or water mass jetted in the air.

[0005]

According to the present invention, a high-pressure water supply source, a header pipe to which high-pressure water is supplied from the high-pressure water supply source, and a header pipe communicating with the header pipe at a predetermined pitch in the pipe axial direction. A plurality of swivel pipe joints attached, and a fountain nozzle attached to the movable side member of each of these swivel pipe joints,
Swing blades mounted on the movable member, jet nozzles for jetting high-pressure water to the swing blades, water pipes for supplying high-pressure water to the jet nozzles, and the jets provided on the water pipes. A control means for controlling the jet water pressure of the nozzle and an urging means for urging the movable member and the swinging blade toward the reference position are provided. We achieved the purpose of having an expression function that allows the water mass to collect the viewpoint and an expression function that allows the water surface to collect the viewpoint.

[0006]

According to the present invention, by supplying high-pressure water from the high-pressure water supply source to the header pipe, it is possible to inject a water column or a water mass from the fountain nozzle into the air to concentrate the viewpoint on the fountain. On the other hand, the landing position of the water column and water mass sprayed in the air is
If the water pressure is constant, it can be changed by the elevation angle of the fountain nozzle. Further, the elevation angle of the water fountain nozzle can be changed by controlling the water pressure of the high-pressure water jetted from the water jet nozzle to the oscillating blades by changing the force against the urging force of the urging means. It is possible. Therefore, by setting the elevation angle of multiple fountain nozzles so that the water column or water mass can be landed at a position where the desired painting or figure can be drawn by connecting the ripples generated on the water surface. Expressing figures and figures on the water surface,
The viewpoint can be collected on the surface of the water.

A plurality of swivel pipe joints (for example, swivel joints) 6 are connected to the header pipes 3 and 3 through a branch pipe 5 provided with a valve 4 at a predetermined pitch in the pipe axial direction. . The swivel pipe joint 6 includes a fixed-side member 6A and a movable-side member 6B, an inlet of the fixed-side member 6A is connected to an outlet of the branch pipe 5, and an outlet of the fixed-side member 6 has an inlet of the movable-side member 6B as an axial line. The movable side member 6B is mounted so as to be rotatable around and liquid-tight, and the outlet of the movable member 6B is closed by a closing member 7, and a shaft 8 attached to the closing member 7
Are rotatably supported by bearings 9.

Movable side member 6B of each swivel pipe joint 6
The fountain nozzle 10 is attached so as to communicate with the inside of the.
Further, a fan-shaped plate 7A is continuously provided on the closing member 7, and the plurality of rocking blades 11A, 11 are projected to one side of the fan-shaped plate 7A.
B and 11C are attached with a predetermined interval.

A jet nozzle 12 for jetting high-pressure water is provided corresponding to the oscillating blades 11A, 11B, 11C. The jet nozzle 12 communicates with the header pipe 3 via a water pipe 13, and the water pipe 13 has a jet nozzle 12
A control valve 14 which is, for example, a motor-operated valve is provided in order to control the injection water pressure. Further, the tip of a spring (pulling spring) 15 is attached to the fan-shaped plate 7A, and the urging of the spring 15 causes the fountain nozzle 10 to move to the position shown in FIG.
Is positioned at the reference position (elevation angle θ) indicated by the solid line.

Are individually varied to swing the figure corresponding to the fish, and the fish swims. In addition to being able to express the state in which it is standing, it is also possible to express other favorite figures and paintings. Moreover, it is possible to continuously express the scale of the figure or painting that has been expressed and the changes from the figure or painting that has been expressed to other shapes or paintings, thus ensuring a dynamic element that appeals to the visual sense. Therefore, the degree of concentration of the viewpoint on the water surface can be further improved.

In the above embodiment, the pair of header pipes 3 and 3 are arranged in parallel with each other at opposite ends in the width direction of the fountain 2, but at one end of the fountain 2 in the width direction. A configuration in which one header tube 3 is arranged or a configuration in which the header tube 3 is formed in a circular ring shape and arranged may be adopted.

[0015]

As described above, according to the present invention, by supplying high-pressure water from the high-pressure water supply source to the header pipe, a water column or a water mass is jetted into the air from the fountain nozzle to concentrate the viewpoint on the fountain. In addition to being able to make it possible, by connecting ripples generated on the water surface due to landing of a water column or a water mass, it is possible to express a desired painting or figure on the water surface, and to collect the viewpoint on the water surface. That is, the function of expressing a water column or water mass by intermittently or continuously spraying it from the fountain nozzle into the air, and the ripples generated on the water surface by the falling water of the fountain make it possible to see various paintings and figures on the surface of the campus.
