Abstract

PURPOSE:To make high-crest wave with small amount of movement by providing a driving device that drives a water tank body to reciprocate horizontally to the outside of the water tank body that is movably installed on a floor. CONSTITUTION:Rollers 3 are provided between a water tank body 1 and the ground surface 4. Then forcible horizontal reciprocation is given to the water tank body 1 by operation of a driving device 5, and progressive wave in a specific cycle is developed therewith over the surface of the water 2. Cycle of the horizontal reciprocation of the water tank body 1 produced by the driving device 5 is made identical with the specific cycle of horizontal swing vibration. The water in the water tank body 1 is then made to resonate and synchronize, and high-crested progressive wave is developed therewith, making the surface of the water go up and down along the wall of the water tank body 1. Thereby the surface of the water becomes capable of making large-scale up-and-down movement even by very small amplitude in forcible horizontal reciprocation given to the water tank body 1.

Regarding wave-making tanks such as ).

[Conventional technology]

Fig. 10 shows a conventional wave-making water tank. When creating waves on the water surface 02 of the water tank 01, the wave-making plate 07 is horizontally moved by the wave-making plate driving device [06] installed on one side of the water N01. is being driven in the direction of the arrow.

[Problem to be solved by the invention]

In the conventional device described above, in order to create a large wave height (also referred to as a maximum wave, a transient response wave, or a single large wave) in the water tank 01, a long pool is required. Furthermore, when creating large wave heights, for example, waves with short wavelengths are created first and then they are allowed to travel. It is necessary to create waves with high wave speeds and long waves one after another and to superimpose the waves, and it is necessary to give a special signal to control the wave-making plate driving device 06.

The present invention can easily create various large wave heights in an aquarium, and is suitable for entertainment purposes such as theaters. A drive device was provided to reciprocate the water tank in the horizontal direction.

(2) In the wave-making aquarium of (1) above, a plurality of slow-stretching materials were arranged vertically on the inner side surface of the aquarium body intersecting the moving direction of the aquarium body.

(3) On the outside of the aquarium body, which is movably placed on the floor,
A first drive device that reciprocates the water tank body in a horizontal direction, and a second drive device that reciprocates the water tank body in a direction crossing the first drive device.

(4) A spindle for supporting the aquarium body, and a swing drive device for reciprocating the aquarium body, which is disposed at a position apart from the spindle.

(5) On the outside of the aquarium body, which is movably placed on the floor,

(6) The wave-making aquarium of (5) above includes a cover provided on a portion other than the front surface of the transparent plate portion, and a background material provided on the back body surface of the aquarium.

[Effect]

In the present invention (1), traveling waves are created on the water surface within the tank main body by horizontally reciprocating the tank main body using the drive device. When the period of this horizontal reciprocating motion is made to match the natural period of the shaking vibration of the water surface inside the aquarium body, the water in the aquarium resonates and synchronizes to create waves with large wave heights, and these waves with large wave heights are caused by the aquarium itself. It moves up and down along the wall of the tank, and becomes a single traveling wave that moves inside the tank itself.

In the present invention (2), according to the above-mentioned present invention (1), a plurality of buffer materials provided on the inner surface of the aquarium body intersecting the reciprocating direction cause a traveling wave generated within the aquarium body to move inside the aquarium body. The impact when a person or object collides with the wall of the aquarium body is reduced. ! In addition, since the buffer material is arranged vertically, it does not attenuate waves within the tank body.

In the present invention (3), waves traveling in two directions are generated by reciprocating the water tank body in two directions.

When the period of each reciprocating motion is made to match the natural period of vibration of the water surface in each direction in the water tank body, waves traveling in two directions with high wave heights are created. Furthermore, this makes it possible to generate a swirling flow within the rectangular water tank body.

In the present invention (4), a traveling wave is created on the water surface within the tank main body by swinging the tank main body about the support shaft 1 by the swing drive device. When the period of the rocking motion of the aquarium body matches the natural period of the water in the aquarium body, the water in the aquarium body resonates and synchronizes to create waves with large wave heights, and these waves with large wave heights are large and cause the water in the aquarium body to It moves up and down along the wall and becomes a primary traveling wave that moves inside the tank body.

In the present invention (5), waves generated within the aquarium main body are viewed through the transparent plate.

In the present invention (6), the waves generated inside the aquarium body are viewed through a transparent plate, but the obtrusive movement of the aquarium body is hidden by the cover, and the audience can see the height of large waves inside the aquarium body with the background material as a background. You can watch the waves, etc.
