Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a fountain device that illuminates a fountain or other decorative item with light emitted from the tip of an optical fiber.

[Conventional technology]

The above-mentioned type of fountain device is known to be excellent in safety because an optical fiber is passed through the water without the risk of electrical leakage, and moreover, it can provide a novel decorative effect. In such fountain devices, conventionally,
A floodlight to project light onto the optical fiber is installed outside the aquarium, and the tip of the optical fiber guided from the installation point of the light transmitter is placed around the nozzle that spouts water in the aquarium or other fountain devices. They were placed around various attached ornaments.

[Problem that the invention attempts to solve]

However, if the floodlight is installed outside the aquarium as in a conventional water fountain system, the required length of the optical fiber between the floodlight and the nozzle is relatively long, which reduces light transmission loss. Not only does it become impossible to ignore, but the optical fibers drawn out to the outside of the aquarium and the floodlights installed outside the aquarium stand out, spoiling the overall aesthetics of the fountain system.
As a result, the decorative effect of the fountain device is halved, and moreover, a large space is required to install the fountain device. In addition, the installation of the optical fiber is time consuming and requires a long optical fiber, which impairs economic efficiency.

This idea solves the above problems.By installing the floodlight integrally with the aquarium, it is possible to make the transmitter less noticeable and prevent deterioration of the overall aesthetic appearance. It is an object of the present invention to provide a fountain device that can reduce the required length of the fountain device to minimize light transmission loss, and can be easily installed in a narrow space.

[Means for solving problems]

In order to achieve the above object, the fountain device of this invention closes the transparent hole formed in the side wall of the water tank with a transparent plate, and provides a floodlight on the outer surface of the transparent plate.
The base end of the optical fiber, which receives the light from the projector that has passed through the light-transmitting plate, is disposed on the inner surface of the light-transmitting plate.

In such a fountain device, the side wall of the aquarium is configured in an inverted V shape by an inner plate and an outer plate, and a floodlight is installed in the space between the inner plate and the outer plate, or the water surface is covered inside the aquarium. You are free to arrange a board and spread artificial grass, artificial flowers, etc. on top of this board.

[Effect]

According to the above means, the light emitted from the projector is transmitted through the light-transmitting plate and is received at the base end of the optical fiber, and the light is emitted from the distal end of the optical fiber. The fountains and other ornaments are then illuminated, creating a novel decorative effect.

Furthermore, if the transmitter is installed in the internal space of the inverted V-shaped side wall, the transmitter will be completely covered by the side wall and will not be visible from the outside. If you cover the floor with artificial grass or artificial flowers, the sound of water droplets ejected from the nozzle falling will be suppressed.

〔Example〕

FIG. 1 is an overall schematic sectional view of the fountain device of this invention. In the same figure, 1 is a water tank, and its side wall 2
is formed into a V-shape by an inner plate 3 that expands upward and an outer plate 4 that narrows upward and slopes slightly upward, and the inner space S thereof is open at the bottom.
A submersible pump 6 is installed on the bottom plate 5 of the water tank 1, and the stored water W in the water tank 1, which is pumped by this submersible pump 6, is sent to a nozzle 8 through piping 7. The structure is such that the air can be blown up to a predetermined height. Although the number and arrangement of the nozzles 8 can be variously adopted, in the illustrated fountain device, as shown in FIG. The nozzles are arranged at equal intervals on the same virtual circle.

As shown in FIG. 3, a through hole 9 is formed at one or several predetermined locations on the inner plate 3 of the side wall 1, and this through hole 9 is formed by an acrylic resin plate or glass fixed to the inner plate 3. It is closed by a translucent plate body 10 made of a plate or the like. The inner surface of the transparent plate 10 holds the proximal end of the optical fiber 11, and the end surface 11 of the optical fiber 11 is held on the inner surface.
A fiber fitting 12 is arranged to accurately bring the light-transmitting plate 10 into close contact with the light-transmitting plate 10. optical fiber 1
The tip of the nozzle 1 is arranged around the nozzle 8.
Note that the tip of the optical fiber 11 may be arranged not only around the nozzle 8 but also around decorative items such as artificial grass and artificial flowers, which will be described later. On the other hand, at a predetermined location on the outer surface side of the translucent plate body 10, in the illustrated example, the inner plate 3
A floodlight 14 is provided on the outer surface of the housing via a fixture 13. Translucent plate 10, fiber fitting 1
2 and the mounting tool 13 are the mounting bolts 1 as shown in the example.
5 or may be fixed to the inner plate 3 by other means. In addition, as shown in the illustrated example, by inserting packings 16 and 17 between the inner plate 3 and the translucent plate 10 and between the inner plate 3 and the fixture 13, the translucent plate It is desirable to ensure watertightness of the mounting parts such as 10.

In FIGS. 1 and 2, reference numeral 18 is a strong plate having a large number of through holes 19, such as a punching plate. This plate 18 is installed at the upper end of the inner plate 3, and the surface of the stored water W in the water tank 1 is covered and hidden by this plate 18. Further, an opening 20 is formed in this plate 18 at a location opposite to the nozzle 8, and the structure is such that the water jetted from the nozzle 8 is blown up to a predetermined height. The above-mentioned opening 20 is provided on the upper surface of the plate body 18.
Artificial grass 21 is spread over the entire area except for the artificial grass 21, and artificial flowers 22 are decorated at appropriate places of this artificial grass 21, such as the outer periphery and around the opening 20. Natural grass or flowers may be used instead of the artificial grass 21 or artificial flowers.

According to such a fountain device, compared to a conventional fountain device in which the floodlight 14 is installed outside the aquarium 1, the required length of the optical fiber 11 is very short, so there is almost no transmission loss of light, and The work of laying the optical fiber 11 is simplified, the required length of the optical fiber 11 is shortened, and economical efficiency is improved.

Further, since the projector 14 is installed in the internal space S of the side wall 2, the projector 14 is completely invisible from the outside. Therefore, the aesthetic appearance caused by the projector 14 being conspicuous is eliminated. Moreover, the space for installing the fountain device is small.

When the submersible pump 6 is operated to eject the water W stored in the water tank 1 from a large number of nozzles 8, the water is blown up to a predetermined height and then falls onto the artificial grass 21 and artificial flowers 22. Therefore, the sound of falling water does not become too loud. Regarding this point, if there is no artificial turf 21, artificial flowers 22, or plate 18, the water blown up from the nozzle 8 will fall onto the surface of the stored water W, and the collision sound will be a loud and harsh rasp. The problem is that it becomes the sound of water, and this water sound becomes noise. However, in the illustrated example, such a harsh sound of water does not occur, so the fountain device does not become a noise source, and furthermore,
Those who view the fountain feel calm, and the sound of water falling on the artificial grass 21 and artificial flowers 22 feels more pleasant than noise. These artificial grass 21 and artificial flowers 22 are of great use in decorating the entire fountain device. A similar sound-absorbing effect can be obtained by covering the plate 18 with various materials that dampen the sound of falling, such as fine sand, instead of the artificial grass 21 or the artificial flowers 22. Also, plate 1
8 itself has great strength, so even if an infant, child, or small animal falls, it can sufficiently catch it. Therefore, high safety can be ensured against such unexpected situations. moreover,
If you do it as shown in the example, the submersible pump 6, piping 7, and other incidental equipment will not be visible to those viewing the fountain, and the water blowing up and the lighting will make you wonder, ``Why is it like that?'' It creates a sense of mystery and can be enjoyed by the viewer. In other words, since the various techniques applied to the fountain are not revealed, it becomes more than just a decorative effect; it also leaves a strong impression. In addition, nozzle 8
The height of the water column blown up from the screen can be freely configured to vary depending on, for example, changes in the brightness or hue of the music or surrounding lighting.

By the way, as in the embodiment, by forming the side wall 1 in an inverted V shape, an internal space S is formed in the side wall 1.
When provided, not only the floodlight 14 but also a filtration device (not shown) for the stored water W can be housed in the internal space S. When water pressure is generated by a land-based vacuum pump instead of the submersible pump 6, the vacuum pump 2
It is also possible to store 3. Therefore, there is an advantage that by accommodating only the piping 7 leading to the nozzle 8 inside the water tank 1, the overall height of the fountain device can be kept low. Furthermore, there is no need to worry about the pumps or the floodlight 14 coming into contact with people, increasing safety. Furthermore, when the side wall 2 is formed into an inverted V-shape by an inner plate 3 that expands upward and an outer plate 4 that is slightly tapered upward, the external shape makes the aquarium 1 feel larger. In addition, the amount of stored water W can be reduced, and the side wall 2 of the water tank 1 feels thicker.
Regardless of the material of the aquarium 1, it feels heavier,
It creates a high-class image and is in line with recent trends toward luxury. Also, the inclination angle of inner plate 3 is set to 45
If the taper angle is set to a large taper angle of approximately 100°, the water surface will be set at a high level even if the stored water W is small, if the water surface is visible by omitting the plate 18, artificial grass 21, or artificial flowers 22 described above. This has the advantage that the fountain feels close to the viewer, and the internal space S of the side wall 1 is very large, which is convenient for storing various machinery and incidental equipment such as cleaning tools.

[Effect of idea]

As explained above, the fountain device of this invention is
A floodlight was placed on the outside of the translucent plate that covered the hole formed in the side wall of the aquarium, and the light from the floodlight was emitted through optical fibers to illuminate the fountain and other decorations. Although the advantages of traditional fountain devices such as no risk of electrical leakage and a novel decorative effect are not compromised, the floodlight is installed integrally with the aquarium, and as a result, the distance between the floodlight and nozzle is reduced. The required length of the optical fiber that is laid between the aquarium and the aquarium is very short, and as a result, not only is there almost no light transmission loss, but also the optical fiber that is drawn out to the outside of the aquarium and the optical fiber that is installed outside the aquarium. The floodlight stands out and does not detract from the overall beauty of the fountain system. Furthermore, the work of laying the optical fiber becomes easier, and the optical fiber becomes shorter, which also improves economic efficiency.
