Abstract

SOLUTION: The exciters 3 are arranged at specified intervals on the circumference of a pond 1.

Sets of the amplitude overlap on each other in the central part a and the waves of the patterns projecting like Mt. Fuji (Konide volcano) are obtd. The elements of the water surface patterns, such as the water columns and splashes generated in the case the waves generated by the respective exciters 3 are concentrated to one point, in addition to basic waves of ripples, stationary waves and large waves are generated by combining the control of the positions where the wave heights and waves 4 interfere with each other. As an example of the program of the water surface patterns, the elements described above are momentarily changed one after another.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water surface pattern generating device applied to a facility for the purpose of recreation, such as a fountain or a pond in a park, or a decoration.

[0002]

2. Description of the Related Art As a similar device for generating a pattern on a water surface, a fountain 22 formed by a fountain tube 21 as shown in FIG. 11 has been conventionally used. In addition, as a similar device in terms of generating a wave, as shown in FIG. 12, there is a wave generator using a water flow or the like which flows out intermittently from an outlet 23 on a side surface.

[0003]

The above-mentioned conventional water surface pattern generating apparatus has the following problems.

(1) In the case of a fountain, when a water surface pattern is generated, the water surface pattern is limited by the laid fountain pipe pattern, and the degree of freedom of the water surface pattern is limited.

(2) In the case of a wave generator, only a large constant wave is generated, and various water surface patterns cannot be generated.

[0006]

The present invention employs the following means to solve the above-mentioned problems.

That is, as a water surface pattern generator, a plurality of vibrators arranged in a fluid and control signals are sent to the vibrators to control the respective amplitudes and phases by a program so as to form a predetermined water surface pattern. And a control device that performs the control.

In the above description, for example, the vibrators are arranged at equal intervals on the circumference in the fluid. Then, from the control device, for example, when the amplitude and the phase of each exciter are controlled to be the same so that a traveling wave having the maximum amplitude is generated at the center, the center overlaps the amplitude, and the shape of the pattern protrudes like Mount Fuji. Waves are obtained.

In addition, when the amplitude and phase of each exciter are controlled by a predetermined program, that is, a temporal pattern, according to the pattern to be generated, various patterns can be generated by interference of traveling waves from each exciter.

In this manner, various water surface patterns can be generated with a large degree of freedom.

BEST MODE FOR CARRYING OUT THE INVENTION

(1) A first embodiment of the present invention will be described with reference to FIGS.

In FIG. 1, around the pond 1 at regular intervals. The exciter 3 is arranged. Each exciter 3 is connected to a control device 5.

As the vibrator 3, there is one as shown in FIGS. Fig. 7 shows a shaft 6 that can vibrate in the axial direction.
, A plurality of disks 7 are attached. In FIG. 8, a rectangular plate 9 is attached to a swing shaft 8.

FIG. 9 shows a case in which a rectangular diaphragm 11 which is arranged perpendicular to the axis of the opening b and vibrates in the axial direction is placed in a cylindrical case 10 having a rectangular opening b on the side surface. is there.

In the above, when the amplitude and the phase of each of the vibrators 3 are controlled to be the same from the control device 5 so that the traveling wave 4 having the maximum amplitude at the center portion a is generated, the amplitude at the center portion a is increased. Waves overlapping and protruding like Mt. Fuji are obtained.

By combining the control of the wave height and the position at which the wave 4 interferes, when the waves generated by the respective vibrators 3 are concentrated at one point in addition to the basic waves of ripples, standing waves, and large waves Water pattern elements such as water columns and splashes can be generated.

An example of a program for a water surface pattern is to change the above elements from time to time.

FIGS. 2 to 6 are examples of calculation of a water surface pattern that can be generated. This means that 12 exciters are evenly arranged on a circumference of 3m radius on the pond water surface, wave frequency 0.5Hz,
This pattern is generated when waves having a wavelength of 1 m and an amplitude of 10 cm are generated in the same phase.

At this time, the amplitude of the wave synthesized at the center of the circle is about 60 cm. And the water surface pattern is (a) ~
(I) is repeated cyclically.

At this time, the energy required for generating the wave is about 4 W per one of the vibrators 3.

Although the example of the water surface pattern has been described above, it is needless to say that it is possible to realize another water surface pattern only by changing the control contents (program) of the control device 5.

Further, it is possible to add this embodiment to a conventional fountain, and to create a more abundant water surface pattern with both the waves and the fountain.

(2) FIG. 10 shows a second embodiment of the present invention.
This will be described below. A plurality of illumination windows 15 are provided on one end surface of the flat cylindrical opaque container 13. Then, a plurality of illumination lamps 16 are arranged inside. Further, the vibrators 3 protruding outward are arranged at equal intervals around the window 15 side. Each exciter 3 is connected to a control device 5 in a container 13. 19 is an outlet.

A transparent container 14 having a transparent cylindrical and arc-shaped end surface is connected to one end surface of the container 13. The colorless liquid 17 and a colored liquid 18 such as blue having a higher specific gravity than the colorless liquid 17 are filled.

In the above, when vibrated by the vibrator 3, the wave 4 having a predetermined pattern is formed at the boundary between the colored liquid 18 and the colorless liquid 17.
Occurs. Light from the lamp 16 is scattered on the surface of the wave 4 and exits from the transparent container 14. Therefore, various wave patterns can be displayed in rich colors.

This embodiment can be used for auxiliary lighting in a room, an interior, and the like. Alternatively, the lighting may be turned upside down to provide illumination from the ceiling.

[0027]

According to the present invention as described above,
Since various desired water surface patterns can be generated, it is very useful for parks and decoration purposes.
