[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wave making device that can artificially generate waves in a water tank, a pool, a sea pond, or the like.
[0002]
[Prior art]
Conventionally, wave generators used in aquariums, pools, sea ponds, and the like are classified as shown in FIG. That is, (A) flap type, (B) piston type, (C) plunger type, (D) air type, and (E) water level difference type.
[0003]
In the flap type of (A), the wave making body 8 configured to be swingable is reciprocated by an external drive device 9 to be driven swingably to generate the wave 7. In the piston type of (B) and the plunger type of (C), the wave forming bodies 10 and 11 are reciprocated and moved up and down by the external driving device 9 to generate the wave 7. In the pneumatic type (D), a normal control valve 14 and an exhaust valve 15 are controlled by an external drive device in order to allow air from the blower 13 to enter and exit from an air chamber 12 installed at one end of a water tank, a pool, a sea pond or the like. The water level difference is generated between the air chamber, the water tank, the pool, the sea pond and the like, and the wave 7 is generated. The water level difference formula of (E) drops water by storing water in a water tank 16 installed at one end of a water tank, a pool, a sea pond, etc. with a pump 5 for a certain period of time and opening the shut-off valve 17 at once with an external drive device 9 And the wave 7 is generated by the impact.
[0004]
The conventional wave generator has the following problems. That is, in the conventional wave-making apparatus, the wave-making body is a wave-forming body in each type (A), (B), and (C), and a valve that performs control in each type (D) and (E). In order to drive and control the valves and the like, an external driving device is indispensable. For this reason, an installation space for the external drive device is required in addition to the wave-making body, and an external drive device and a soundproofing device for preventing noise from the blower 13 and the like are also required. Further, (D), (D In the model E), an air tank 12 and a water tank 16 made of concrete or the like are required, and the facilities and foundations are large-scale. Also, in order to make waves, it is necessary to accurately control the wave forming body, valves, etc., so the mechanical structure is complicated, there are many components, and the manufacturing cost is expensive, and it is very expensive for maintenance and maintenance.

[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a preferred embodiment of a wave making device according to the present invention will be described with reference to the drawings. FIG. 1 is a sectional side view (a) and a plan view (A) of a wave making apparatus showing a preferred embodiment of the wave making apparatus according to the present invention, in which 1 is a wave making body and 2 is a wave making. A body support part, 3 is an opening part, 4 is a protruding plate part, 5 is a device such as a pump that allows liquid to flow into the wave forming body, and 6 is a liquid inflow hole.
[0008]
Further, the wave making device is a wave making device characterized in that it is provided with a wave drive body 1 that is hollow and has an opening 3 and can store a liquid therein and can be driven to rotate. ing.
[0009]
Further, the wave generator described above is a wave generator characterized in that an external drive device is not required for driving the wave generator 1. Here, the external drive device is a device such as an electric motor that is assumed to rotate the wave forming body 1 by supplying rotational force to the wave forming body 1 from the outside. The pump 5 or the like is a device that supplies liquid from the opening 3 to the wave forming body 1 and does not hit the external drive device.
[0010]
Further, the wave making device includes, for example, a protruding plate portion 4 protruding from one side portion of the opening 3 in the wave making body rotation direction in order to make the wave making body 1 rotate. It is a wave making device in which the body 1 is adjusted and supported by the wave making body support portion 2 so as to rotate at least efficiently and make necessary waves.
[0011]
Next, a wave making procedure in this wave making device will be described. [0012]
Initial step) as shown in (1) of FIG. 1 and FIG. 2, Zohatai 1 has a cylindrical shape, since it has an opening 3, the side of the container wall of the opening 3 in the Zohatai 1 Concrete Namitai 1 of the center of rotation relates to the INO than light axisymmetric side of the container wall, relates the rotation center of Zohatai 1, farther from the opening 3 side (the lower side in FIG. 2 (1)) is positioned lower, At the start of liquid inflow, the opening 3 in the wave making body 1 faces the liquid inflow hole 6 and the wave making body 1 is balanced. At this time, the wave-making body 1 is slightly inclined toward the protruding plate portion 4 by the weight of the protruding plate portion 4, and the edge on the protruding plate portion 4 side of the opening 3 is slightly lower than the opposite edge. .
[0013]
(Storage process) Next, as shown in (2) of FIG. 2, the liquid flowing in from the liquid inflow hole 6 continues to be stored in the wave forming body 1, and eventually the wave forming body 1 is filled with the liquid. The liquid overflows from the protruding plate portion 4 of the opening 3.
[0014]
(Rotation step) Next, as shown in FIG. 3 (3), the wave body 1 starts rotating by the action of the liquid overflowing from the protruding plate portion 4 of the opening 3, and the liquid overflowing from the opening 3 Due to the action, the rotation speed of the wave forming body 1 is further increased. Here, the wave body 1 starts to rotate by the action of the overflowing liquid, as shown in FIG. 2 (2), exceeding the weight of the liquid accumulated in the protruding plate portion 4 and the protruding plate portion 4. This is because the rotating body loses its balance due to the weight of the liquid flowing down the side wall of the wave-making body 1 and the wave-making body 1 is further inclined toward the protruding plate portion 4 side . Also, the rotational speed of the wave-making body 1 is increased because the wave-making body 1 that has started rotating due to the weight of the liquid accumulated in the protruding plate portion 4 has a structure in which the protruding plate portion 4 generates the wave in addition to the inertial force. Since the balance of the rotating body is greatly disrupted at the time when it is level with or slightly below the center of rotation of the body 1, the liquid is rapidly discharged from the wave-making body 1, so compared with the initial stage of rotation. This is because it receives a remarkably large rotational force.
[0015]
(Discharge process) The wave forming body 1 continues to rotate, and when the opening 3 faces downward as shown in (4) in FIG. 3, the liquid stored in the wave forming body 1 is drawn all at once. Discharge. A wave 7 is generated by the impact action of the liquid discharged from the opening 3 at this time.
[0016]
The initial process, the storing process, the rotating process, and the discharging process are repeated, and necessary types of waves are repeatedly formed. Here, since the internal space of the wave forming body 1 is emptied after the discharging process, as described with respect to the initial process, the opening 3 side is farther from the opening 3 with respect to the rotation center of the wave forming body 1 (FIG. 3). Since the opening area of the opening 3 is lighter than the upper side in (4), the wave-making body 1 rotates halfway and returns to the initial process posture of FIG.
[0017]
In addition, the magnitude | size, speed, and period of a wave are possible by setting the quantity of the liquid which flows in from the inflow hole 6, and the volume of the wave making body 1 as needed, for example.
[0018]
As described above, in the wave making device according to the present invention, since the wave making body itself is rotationally driven by the action of the flowing liquid, an external drive device is not required for driving the wave making body, and the installation space for the wave making device is large. It is small and no noise is generated when the wave generator is driven. In addition, it has a simple structure that does not require complicated control to drive the wave generator, has few components, can reduce manufacturing costs, and has various advantages such as extremely easy maintenance and maintenance. .
[0019]
【The invention's effect】
As described above, the present invention includes a wave-making body that is hollow and has an opening, and that can store a liquid therein and that can be driven to rotate, and that an external drive device is required to drive the wave-making body. Therefore, compared with the conventional wave generator, the wave generator has various advantages. As described above, as a preferred embodiment of the wave making device according to the present invention, the case where the wave making body has a cylindrical shape has been illustrated and described. However, the present invention is not limited to this embodiment. As for the body, it can be suitably used as long as it is hollow and has an opening, and can store liquid inside, and can be rotationally driven, and various design changes can be made without departing from the spirit of the present invention. Of course it can be done.
