[0002] During the wave test in the pool, in order to eliminate the influence of reflected waves and improve the test accuracy, a wave-breaking device must be installed in the pool. At present, the arc slope device is more commonly used in wave pools, which mainly relies on the friction, vortex and breakage of the waves climbing the slope surface. However, the biggest disadvantage of the arc slope wave-breaking device is that it occupies too large an area of ​​the pool. The maximum wave-breaking wavelength used is close to the length of the wave-breaking device (the direction of the incoming waves), and the wave height cannot be too large. Therefore, how to increase the applicability of the wave-breaking device and reduce the pool area occupied by the wave-breaking device is the main concern of wave-breaking in wave pools.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] The utility model provides a gravity type wave dissipation structure for a wave pool, such as Figure 1 and Figure 2 As shown, the pool includes a pool bottom 1-1, a pool wall 1-2 around the pool bottom 1-1, a wave-breaking net 2-1, and an energy dissipation channel 3; the pool bottom 1-1 and the pool wall 1-2 are cast as a whole to form a cylindrical wave-forming pool 1. The pool wall 1-2 of the wave-forming pool 1 is divided into 3-4 circular wave-facing sections 2 from top to bottom along the vertical direction. Figure 1 The pool wall 1-2 is divided into four wave-facing sections 2 vertically from top to bottom, and spaces for waves to enter are provided between upper and lower adjacent wave-facing sections 2.

[0035] The vertical surface of the pool wall 1-2 is the wave-facing surface of each wave-facing section 2, and the wave-facing surface is inclined so that the width of the wave-facing section 2 gradually decreases from top to bottom; the upper surface of the wave-facing section 2 is the wave-guiding surface 2-2, and the height of the wave-guiding surface 2-2 near the wave-facing surface is higher than that of the other side, and the wave-guiding surface 2-2 is set as an anti-curved arc surface near the wave-facing surface. Figure 2 As shown, the waveguide surface 2-2 has a slope of 15° with the horizontal direction, the upper edge of the wavefront surface of each wavefront segment 2 is more prominent than the lower edge, presenting an inward-sloping surface, and the angle between the wavefront surface and the vertical direction is also about 15°.

[0036] In order to break the waves quickly, a wave-breaking net 2-1 is hung on the wave-facing surface, and the falling point of the wave-breaking net 2-1 is located in the wave-guiding surface 2-2 of the adjacent next layer of the wave-facing section 2, so that the next stage of wave breaking can be carried out through the wave-guiding surface 2-2.

[0037] The shape of the wave-breaking net 2-1 can be referred to Figure 1 or Figure 2 It is a lower chute type, which is opposite to the inclination direction of the wavefront and can cope with wave impacts in all directions.

[0038] A flow guiding structure 4 is provided at the lower end of the wave guiding surface 2-2, that is, the side away from the wave front surface. The flow guiding structure 4 includes a flow guiding shaft 4-1 connected to the pool wall 1-2, and flow guiding blades 4-2 distributed on the periphery of the flow guiding shaft 4-1. Figure 4 Multiple guide structures 4 are evenly arranged in the circle formed by the lower end of the waveguide surface 2-2, and the guide axis 4-1 of each guide structure 4 can rotate freely in both directions, thereby achieving wave velocity attenuation and guiding the flow upward or offsetting the gravitational potential energy released by the downward flow.

[0039] For long wavelengths and large waves, it is necessary to use the energy dissipation channel 3 for gravity energy dissipation. The energy dissipation channel 3 is arranged inside the pool wall 1-2. The energy dissipation channel 3 includes a deceleration section 3-1 and a water discharge section 3-2 which are arranged vertically and correspond to the waveguide surface 2-2. The deceleration section 3-1 is located above the end of the waveguide surface 2-2 away from the wavefront surface, and the lower end of the deceleration section 3-1 is connected to the end of the waveguide surface 2-2 away from the wavefront surface; the upper end of the deceleration section 3-1 is connected to the corresponding water discharge section 3-2 through a horizontal section 3-5; each adjacent water discharge section 3-2 is interconnected up and down, and the pipe diameter of the water discharge section 3-2 is smaller than the pipe diameter of the deceleration section 3-1, preferably 1 / 3 to 1 / 4 of the pipe diameter of the deceleration section 3-1. The flow guide structure 4 is arranged at the turning connection between the waveguide surface 2-2 and the deceleration section 3-1. The deceleration section 3-1 realizes the deceleration of the waves through the gravitational potential energy, and the water discharge section 3-2 realizes the reduction of the flow velocity through the change of the pipe diameter, so that the water flows out slowly.

[0040] The wave section 2, the deceleration section 3-1, and the water discharge section 3-2 are all arranged along the circumference of the pool wall 1-2, that is, they surround the pool wall 1-2. The horizontal cross-sectional shapes of the deceleration section 3-1 and the water discharge section 3-2 are the same as the horizontal cross-sectional shapes of the pool wall 1-2, which can be referred to Figure 3 As shown in the AA cross-sectional view (the guide structure 4 is not drawn), the cross-section of the wave pool 1 is annular, and the deceleration section 3-1 and the water discharge section 3-2 of each wave section 2 are arranged in a circle around the pool wall 1-2, and the horizontal cross-sectional shape is also annular.

[0041] A horizontal energy dissipation and diversion section 3-3 is provided at the intersection of the upper and lower adjacent water discharge sections 3-2, and the pipe wall of the energy dissipation and diversion section 3-3 is a corrugated pipe wall. An energy dissipation and confluence section 3-4 connected to the lowest point of the water discharge section 3-2 is provided horizontally on the surface of the pool bottom 1-1, and the energy dissipation and confluence section 3-4 is located below the last layer of the incoming wave section 2, and the pipe wall of the energy dissipation and confluence section 3-4 is a long corrugated pipe wall. The lowest point of the water discharge section 3-2 converges at the energy dissipation and confluence section 3-4, and flows back to the wave pool 1 through the energy dissipation and confluence section 3-4.

[0042] The effusion structure 5 is evenly arranged in sections within the circumference formed by the lowest point of the water discharge section 3-2 and the connection point of the energy dissipation confluence section 3-4. The structure and arrangement of the effusion structure 5 can refer to the diversion structure 4. The effusion structure 5 includes an effusion shaft connected to the pool wall 1-2 and effusion blades distributed on the periphery of the effusion shaft. The effusion shaft can be connected to a motor. The water flow is allowed to rotate freely through the effusion shaft and then decelerated by the corrugated pipe wall. The motor can also be pressed to make the effusion shaft rotate in the opposite direction of the water flow.

[0043] The gravity wave-absorbing structure of the utility model can be applied to scenes with different wavelengths and wave heights. Its applications in different scenes are as follows:

[0044] Application scenario 1: low wave height, short wavelength

[0045] The wave impacts the wave-breaking net 2-1, and the wave-breaking net 2-1 breaks the wave and slides it into the wave-guiding surface 2-2. The wave climbs upward along the slope of the wave-guiding surface 2-2, and falls after attenuation.

[0046] Application scenario 2: medium wave height, medium wavelength

[0047] The wave hits the wave-breaking net 2-1, and the wave-breaking net 2-1 breaks the wave and slides it into the wave-guiding surface 2-2. The wave climbs upward along the slope of the wave-guiding surface 2-2, pushing the guide shaft 4-1 to rotate forward and then rise along the deceleration section 3-1. After attenuation, it falls back along the deceleration section 3-1, pushing the guide shaft 4-1 to rotate backward and fall back. The guide shaft 4-1 can rotate freely in the forward and reverse directions, and the guide blades 4-2 continue to break the waves broken by the wave-breaking net 2-1. When the guide shaft 4-1 rotates forward, the wave speed can be attenuated and the wave is directed upward. The guide shaft 4-1 rotates backward to offset the gravitational potential energy released by the water flow in the deceleration section 3-1.

[0048] Application scenario 3: large equal wave height and large equal wave length

[0049] The wave hits the wave-breaking net 2-1, and the wave-breaking net 2-1 breaks the wave and slides it into the waveguide surface 2-2. The wave climbs upward along the slope of the waveguide surface 2-2, pushing the diversion shaft 4-1 to rotate forward and then rise along the deceleration section 3-1, entering the water discharge section 3-2 through the horizontal section 3-5. The diameter of the water discharge section 3-2 is 1 / 3-1 / 4 of the diameter of the deceleration section 3-1. The flow rate descending from the water discharge section 3-2 is reduced by changing the diameter. The upper layer of the water discharge section 3-2 is connected to the lower layer of the water discharge section 3-2 through the energy dissipation diversion section 3-3 to reduce the gravitational potential energy released by the descending water flow. The water discharge section 3-2 at the bottom flows back to the pool through the energy dissipation confluence section 3-4. You can choose to let the flow discharge shaft rotate freely to decelerate the water flow through the corrugated pipe wall, or you can choose to press the motor to make the flow discharge shaft rotate in the opposite direction of the water flow to reduce the confluence speed of the water flow.

[0050] Application scenario 4: non-working condition, the wave-breaking channel is cleared.

[0051] Pressing the motor makes the discharge shaft rotate in the same direction as the water flow, so that the water in the channel is discharged faster.

[0052] The above examples of the utility model are described in detail, but the content is only the preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
