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,
A cylinder device for controlling the swing angle of the movable side member and the fountain nozzle, and an expression function for collecting a viewpoint on a water column or a water mass injected in the air,
We achieved the purpose of having an expressive function that brings the viewpoint to the surface of the water.

[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 fountain nozzle can be changed by activating the cylinder. Therefore,
By setting the elevation angle of multiple fountain nozzles so that the water column and water mass land on the position where you can draw the desired painting or figure by connecting the ripples generated on the water surface, the desired painting or figure You can express such things on the surface of the water so that the viewpoint can be collected on the surface of the water.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing an embodiment of the present invention, FIG. 2 is an enlarged plan view of an essential part, and FIG. 3 is a sectional view taken along the line AA of FIG. 2. In these figures, the water painting fountain device is It has a pump 1 and a pair of header pipes 3, 3 which are arranged parallel to each other at both ends in the width direction of the fountain 2, and high pressure water is supplied from the pump 1 to these header pipes 3, 3.

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, the outlet of the movable-side member 6B is closed by a closing member 7, and is rotatably supported by a bearing 7A standing on the water bottom 2A, and the swing arm 8 is radial. It is extended to the outside.

A fountain nozzle 10 is attached so as to communicate with the inside of the movable member 6B of each swivel pipe joint 6. The movable member 6B and the fountain nozzle 10 are configured to swing by the cylinder device 9.
The cylinder device 9 is, as shown in FIG.
A, a hydraulic cylinder 9B, a hydraulic master cylinder 9C and a plunger pump 9D are provided, and the piston rod 9c of the hydraulic master cylinder 9C and the piston rod 9b of the hydraulic cylinder 9B are provided by the operation of the plunger pump 9D.
As the piston rod 9a of the swing cylinder 9A moves forward and backward, the movable side member 6B and the fountain nozzle 10 are moved through the swing arm 8 connected to the tip of the piston rod 9a. Is configured to swing.

Next, the operation of the above configuration will be described. By operating the pump 1 and supplying high-pressure water to the header pipes 3 and 3, it is possible to inject a water column or a water mass into the air from a plurality of fountain nozzles 10, 10 ... to concentrate the viewpoint on the fountain. .

On the other hand, by activating the plunger pump 9D of the cylinder device 9 and operating the swing cylinder 9A via the hydraulic master cylinder 9C and the hydraulic cylinder 9B, the fountain nozzles 10, 10 ... It is possible to change steplessly within the range from the reference position (elevation angle θ) shown by the solid line to the vertical position shown by the chain double-dashed line. Therefore, if the water pressure from the fountain nozzles 10, 10 ... Is constant, the fountain nozzles 10, 10 ... Are steplessly changed in the range from the reference position to the vertical position, so that the fountain nozzles 10, 10 ... It is possible to change the landing position of the water column or water mass injected into the air from ... infinitely. As a result, the elevation angles of the fountain nozzles 10, 10, ... Are individually set to predetermined values, and the ripples generated on the water surface are linked, so that a figure corresponding to a fish is expressed on the water surface, for example, as shown in FIG. Then, you can let the viewpoint gather on the surface of the water.

Further, by the operation of the cylinder device 9,
By varying the elevation angles of the fountain nozzles 10, 10 ... individually, the figure corresponding to the fish is swung, and
In addition to being able to represent the state in which a fish is swimming, 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 both 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.
Further, the piston rod 9a of the swing cylinder 9A may be configured to be directly moved back and forth by a forward / backward mechanism such as a cam device or a crank device.

[0014]

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. By expressing it, it is possible to exert both functions of attracting the viewpoint on the water surface.
