Description

[Detailed Description of the Invention] The present invention relates to a water supply device for an aquarium, and in particular can easily prevent ripples on the water surface caused by water supply.

In water tanks such as water receiving tanks and elevated water tanks, where a water supply pipe that penetrates from the outside to the inside is installed at the top of the side wall, when water falls from the water supply pipe, the water surface will ripple, leading to malfunction of the level gauge that controls the water level. Also, the sound of water being supplied when falling into water was loud. Conventionally,
It is known to provide a downpipe connected to a water supply pipe and to position the lower end of the downpipe below the water surface.

In this case, especially for aquariums with a large amount of water supply, it is necessary to prepare a pipe with a large diameter commensurate with the amount of water supplied, and it is also necessary to install the water supply pipe vertically from the tip to near the bottom wall of the aquarium, and to fix the downpipe to the aquarium. However, it was not economical and required time and effort.

The present invention improves these conventional drawbacks, and in an aquarium equipped with a water supply pipe that opens downward, a breakwater tube with buoyancy is placed above the water surface below the water supply pipe, and the opening is used to supply water. It is arranged facing the pipe side, a sliding part is formed in the breakwater tube, and the sliding part of the breakwater tube is engaged with a guide rod installed vertically in the water tank, so that the breakwater tube is guided along the guide rod. The present invention relates to an aquarium characterized by being vertically movable and having a predetermined height of the peripheral wall of the breakwater cylinder exposed above the water surface.

The present invention will be explained in more detail below with reference to the drawings.

FIG. 1 is a partially cutaway sectional view of a main part of an embodiment according to the present invention, and FIGS. 2 to 5 are perspective views of a breakwater cylinder used in the present invention.

In FIG. 1, a water supply pipe 3 that penetrates the upper part of the side wall 2 of a water tank 1 and opens downward is provided, and a guide rod 4 is vertically provided in connection with the water supply pipe 3.
is inserted, and the peripheral wall 51 of the breakwater tube 5 is shown exposed at a predetermined height above the water surface L.

In FIG. 1, the aquarium 1 is shown as being integrally molded from an FRP plate or the like, but the present invention is not limited thereto, and may be an assembly-type aquarium constructed by joining a plurality of unit plates. The guide rod 4 is made of a rod or pipe made of synthetic resin or the like, and although not shown, the upper end is fixed to approximately the center of the water supply pipe 4 by appropriate means.
Further, the lower end portion is fixed to the bottom wall 6 of the water tank 1.

FIG. 2 shows the breakwater tube 5 used in the present invention. The wave-break tube 5 has a cylindrical sliding part 52 arranged approximately at the center of a cylindrical peripheral wall 51, and the peripheral wall 51 and the sliding part 52
A plate-shaped partition member 5 is provided between the
3 is provided. The inner diameter of the sliding part 52 made of a cylindrical body is made slightly larger than the outer diameter of the guide rod 4, and the wave-proof tube 5 can move up and down along the guide rod 4.

The breakwater tube 5 is made of a material having a specific gravity lighter than water, such as a closed-cell synthetic resin (e.g., polystyrene, polyurethane, etc.) foam or a synthetic resin hollow body, so that a predetermined height of the peripheral wall 51 is exposed above the water surface. It has been manufactured.

In addition, as shown in FIG. 3, the breakwater tube 5 is further provided with a plurality of cylindrical walls 54 between the outer wall 51 and the sliding portion 52, so that the water falling from the water supply pipe 5 flows through the cylindrical walls 54. The force of the cylindrical wall body 54 is weakened by
Since the water falls into a plurality of sections separated by a plurality of sections, it is advantageous because it can be effectively extinguished and the sound of water supply can be reduced. The cylindrical wall body 54 is connected to the outer wall 5
1 and the sliding part 52, the partition member 53 made of a rod-shaped body made of synthetic resin or the like is shown in the figure, but if the walls 54 can be fixed at a predetermined interval, other means may be used. It can be adopted as appropriate.
Moreover, as shown in FIGS. 4 and 5, the breakwater tube 5 has an outer wall 51
The sliding portion 52 may also be shaped like a square pipe.

Although the sliding portion 52 of the breakwater tube 5 is cylindrical and is provided in the center of the breakwater tube 5, the present invention is not limited to this. , the guide rod 4 may be fixed at a predetermined distance from the side wall 2, and the wave-break tube 5 may be inserted into the guide rod 4 to be movable up and down. In addition, as long as the breakwater cylinder 5 is vertically movable below the water supply pipe 3, any suitable means can be adopted.

As described above, according to the present invention, a breakwater tube having buoyancy is disposed on the water surface below a water supply pipe with its opening facing toward the water supply pipe, and a sliding portion is formed in the breakwater tube,
The sliding part of the breakwater tube engages with a guide rod installed vertically in the water tank, allowing the breakwater tube to move up and down along the guide rod, and exposing a predetermined height of the breakwater tube above the water surface. As a result, the water flowing out from the water supply pipe falls into the buoyant surrounding wall of the breakwater cylinder regardless of the position of the water storage surface, thereby preventing the water surface from rippling.
In addition, the sliding part formed on the buoyant breakwater tube engages with a guide rod installed vertically in the water tank, making the buoyant breakwater tube movable up and down along the guide rod.
It is easy to construct and can provide reliable wave protection.
Furthermore, if multiple walls are provided inside the breakwater cylinder circumferential wall,
The water falling from the water supply pipe hits the wall and its force is weakened, and the water falls into multiple compartments separated by the wall, so it is effectively eliminated and the sound of water supply can be reduced. It is economical and requires no effort to install, and is of great practical benefit.
