It provides things that competition practitioners can practice surfing tube riding, and ordinary players can feel free to experience surfing tube riding.
  • Surfing is popular all over the world. In recent years, not only marine leisure, but also the number of people who are seriously challenging as a competition is increasing. In order to actually enjoy surfing, you have to go to a coast with a natural environment suitable for surfing.
  • a coast with a natural environment suitable for surfing is a coastline facing the open ocean where large waves are easy to reach, and the rushing waves tend to be so-called large solitary waves that travel toward the coast. It is necessary to have a shallow seafloor topography that facilitates the formation of waves that appear at the same time so that the breaking area of the wave crest and the area immediately before the break continue.
  • the solitary wave does not mean an oscillating wave that repeatedly moves up and down at the same point, but means a wave in which each wave is isolated and progresses with an interval between the waves.
  • Waves that are particularly suitable for surfing are those in which the cross section of the wave is a tube-like wave due to the appearance of the region from the collapse front of the solitary wave to the region immediately before the collapse. Surfers can surf by sliding from the collapse area of the wave front of this tubular winding wave to the area just before the collapse.
  • the beach where waves suitable for surfing are formed is limited to natural conditions, and you cannot enjoy surfing anywhere in the world.
  • the flap-type wave-making device reciprocally swings a half-submerged vertical wave-making plate whose lower end is rotatably supported by a hinge at the bottom of a water tank with the hinge as a fulcrum. It is what causes waves.
  • the wave-making device of the piston is for making a semi-submerged piston attached to the shaft to reciprocate to push and pull along the shaft to generate waves.

It is a wave-making device that generates a wave by moving the water captured by the water carrier to the front by moving it.
  • the various wave forming devices described in the related art have the following problems from the viewpoint of wave forming devices suitable for surfing.
  • the waves formed by the flap-type wave-making device are so-called up-and-down waves that cause the water in the pool to go up and down on the spot, and are not traveling waves that travel independently. Therefore, it is impossible to form a so-called tube-shaped winding wave in which the crests in the region just before the collapse that are suitable for surfing are continuous. Therefore, a winding wave suitable for surfing cannot be formed even if the scale of the device is increased and the power is increased.
  • a flap type wave generator it is necessary to enlarge the flap and deepen the water depth, but it requires too much power to move the amount of water in the pool section and the mechanism becomes complicated. Problems also occur.
  • the wave formed by the piston-type wave-making device is a so-called up-and-down wave that is pushed up and down by the pool water in the same manner as the flap-type wave, so it moves up and down in isolation. Not a progressive wave. Therefore, it is impossible to form a so-called tube-shaped winding wave in which the crests in the region just before the collapse that are suitable for surfing are continuous. Therefore, a winding wave suitable for surfing cannot be formed even if the scale of the device is increased and the power is increased.
  • the air compression type wave generator pushes the water in the pool up and down, so it is a so-called up-and-down wave that is greatly moved up and down on the spot, not a traveling wave that progresses in isolation. .. Therefore, it is impossible to form a so-called tube-shaped winding wave in which the crests in the region just before the collapse that are suitable for surfing are continuous. Also, since a large vacuum pump is used, it cannot be said that it is energy efficient in generating a large wave.
  • the direction of discharge of the stored water becomes a problem, but basically it drops the water directly below the tank chamber standing in the pool, so due to the influence of the weight of the water, After all, it propagates as a so-called up-and-down wave that moves up and down on the spot, and does not become a traveling wave that travels in isolation. Therefore, it is impossible to form a so-called tube-shaped winding wave in which the crests in the region just before the collapse that are suitable for surfing are continuous. In addition, since the water is pumped up and stored in the tank, it is not energy efficient.

Add some ingenuity to the bottom of the pool to make it easier for waves to form.
  • FIG. 19 is a view showing the bottom of the pool 200 of the surfing practice equipment of the present invention for easy understanding. It is a plan view. As shown in FIG. 19, the bottom surface of the pool 200 is provided with a flat portion 210, a slope portion 220, and a trapezoidal portion 230. There is a game area 240 in the center of the pool 200.
  • the flat portion 210 is a flat portion continuing from the movement range in which the container 110 moves. It extends in front of the wave generator for surfing. In this flat portion 210, the water depth of the pool is relatively deep.
  • the slope portion 220 is an upward slope slope provided near the start position of the game area 240 following the flat portion 210.
  • the depth of the water in the pool gradually decreases as it passes through this slope.
  • the slope portion 220 is not provided parallel to the direction of the traveling wave, but is angled. That is, the slope portion 220 is angled with respect to the moving direction of the container body 110.
  • the slope portion 220 has a substantially triangular shape. Due to the angled arrangement of the slope portion 220, the wave that reaches the area of the slope portion 220 at the shortest as the traveling wave travels starts to have a shallow water depth, and the slope portion 220 first. Pass through. The adjacent wave then begins to fall on slope 220, and the adjacent wave then begins to fall on slope 220. In this way, the depth change of the traveling wave gradually occurs from one side to the other.
  • the trapezoidal portion 230 is a trapezoidal portion having a shallow bottom through the slope portion 220. There is a game area 240 in this trapezoidal portion. The back side of the trapezoidal portion 230 approaches the end of the pool, so it is not the game area 240. The reason why the tubular winding wave is easily formed can be explained as follows.
  • the speed of the waves is affected by the depth of the water in the pool. Physically, it is known that the deeper the water is, the faster the wave speed is, and the shallower the water is, the slower the wave speed is. Therefore, by providing the slope portion 220 rising from the flat portion 210, the speed becomes slower as the depth becomes shallower. While passing through the slope portion 220, a velocity difference in the front-back direction of the wave is accumulated, and a so-called tubular winding wave is formed so that the back side of the wave covers the front side, and finally the wave front is formed. It collapses toward the front.
  • the slope portion 220 has a substantially triangular shape having vertices
  • the speed starts to slow down from the position corresponding to the vertices of the triangle, and the speed gradually decreases toward the sides of the triangle.
  • the earliest collapse region occurs at the point corresponding to the apex, and the waves collapse in succession in the lateral direction so as to continue from the collapse region.
  • a tubular winding wave suitable for continuous surfing is created.
  • a pair of left and right tube-shaped winding waves that are divided into left and right with the apex of the triangle as a boundary is formed.
  • the shape of the slope portion 220 may be various as long as it has an angle with respect to the traveling wave.
  • the example of FIG. 20 is an example in which the shape of the slope portion 220 is provided so as to run diagonally.
  • one tubular winding wave is formed from one side of the pool to the other side.
  • the width of the game area must be wide to some extent, and the length of the tubular winding wave that is formed must be long to some extent. It can be said that a configuration in which a plurality of sets of surf wave making devices 100 are arranged in a line as shown in FIG. 13 is also preferable.
  • the surf wave generator of the present invention can be widely applied to artificial surf wave generators installed indoors or outdoors.
