DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a swimming pool, a surf-in pool, an experimental aquarium related to marine vessels, and an aquarium for viewing water and waves (in this specification, these are collectively referred to as aquariums). Etc.).

[Conventional technology]

FIG. 10 shows a conventional wave-making water tank. When a wave is formed on the water surface 02 of the water tank 01, the wave making plate 07 is driven horizontally in the direction of the arrow by a wave making plate driving device 06 provided on one side in the water tank 01.

[Problems to be solved by the invention]

In the conventional apparatus described above, when a large wave height (also referred to as a maximum wave, a transient response wave, or a one-shot large wave) is to be formed in the water tank 01, a long pool is required. Further, when a large wave height is to be produced, for example, a wave having a short wavelength is first produced and then advanced. It is necessary to generate waves having a fast wave speed and a long wavelength one after another to superimpose the waves, and it is necessary to provide a special signal to the control of the wave plate driving device 06.

An object of the present invention is to provide a wave-making water tank that can easily form various large wave heights in a water tank and that is suitable for recreational use such as a theater.

[Means for solving the problem]

 The wave making tank of the present invention has the following measures.

(4) A pivot for supporting the water tank main body and a rocking drive device for reciprocating the water tank main body disposed at a position separated from the support shaft.

(5) A driving device for reciprocating the water tank is provided outside the water tank body movably disposed on the floor, and a part or all of the side surface of the water tank body is formed of a transparent plate.

(6) A cover provided on a portion of the wave-making water tank of the above (5) except for the front surface of the transparent plate portion, and a background material provided on a surface portion of the back body of the water tank.

[Action]

In the present invention (1), a traveling wave is generated on the water surface in the water tank main body by reciprocating the water tank main body in the horizontal direction by the driving device. If the cycle of this horizontal reciprocating motion is matched with the natural period of the oscillating vibration of the water surface in the water tank body, the water in the water tank will resonate and tune to create a wave with a large wave height. It rises and falls greatly along the wall, and travels in the tank body as a traveling wave.

In the present invention (2), in the above-mentioned present invention (1), the plurality of cushioning members provided on the inner surface of the water tank main body intersecting with the reciprocating direction make the water tank generate by the traveling wave generated in the water tank main body. The impact when a person or an object in the main body collides with the wall of the aquarium main body is reduced. Further, since the cushioning member is disposed in the vertical direction, the wave in the water tank main body is not attenuated.

In the present invention (3), a wave traveling in two directions is generated by reciprocating the water tank body in two directions. When the cycle of each reciprocating motion is matched with the natural period of the oscillating vibration in each direction of the water surface in the water tank main body, a wave traveling in two directions with a high wave height is created. In addition, it is possible to generate a swirling flow in the rectangular water tank main body.

In the present invention (4), the traveling wave is generated on the water surface in the water tank main body by rocking the water tank main body around the support shaft by the rocking drive device. When the period of the rocking motion of the water tank body is matched with the natural period of the water in the water tank body, the water in the water tank body resonates and tunes to create a wave with a large wave height. It moves up and down along the wall, and moves in the tank body as a traveling wave.

In the present invention (5), waves generated in the water tank main body are viewed through the transparent plate.

In the present invention (6), the waves generated in the main body of the aquarium are watched through the transparent plate, but the unsightly movement of the main body of the aquarium is hidden by the cover. You can watch the wave height.
