[0002] A wave maker is an infrastructure supporting a wave test pool. Its function is to generate waves with different wavelengths and wave heights in the test pool, simulate the influence of actual waves on ships or buildings, etc., to measure various technical data and provide a basis for relevant designs. Therefore, the main task of the wave maker is to generate waves meeting the requirements, including regular waves and irregular waves, two-dimensional waves and three-dimensional waves, as well as waves with special requirements. With the development of technology, the back-dry synchronous belt wave maker has gradually become the mainstream, with the characteristics of energy saving, high precision, low noise and large load.

[0003] Traditional wave makers usually adopt a structure with water on both sides. There is water on both the front and back sides of the wave-making plate. The wave-making plate swings back and forth, doing work on the water bodies in the front and back. A wave suppressing device needs to be designed on the back to prevent the water body from surging back and forth. This structure has problems of high energy consumption and low efficiency. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a back-dry rocking plate synchronous belt wave maker. The rocking plate has water on one side and no water on the back. The air pressure of the air spring balances the water pressure. When the rocking plate swings back and forth, it only does work on the water body in the front, greatly increasing the wave-making efficiency and reducing the energy consumption by 30 - 40%.

[0005] To achieve the above purpose, the technical scheme adopted by the utility model is as follows: A back-dry rocking plate synchronous belt wave maker includes a fixed frame and a wave-making module arranged on the fixed frame.

The air spring is connected with a controller, and the controller is used to set a constant pressure for the air spring, so as to provide water pressure and the thrust required for wave making for the rocking plate. The driving unit drives the synchronous belt to drive the arc-shaped transmission frame to move, and then drives the rocking plate connected to the arc-shaped transmission frame to move.

[0006] As a preferred scheme, it further includes an air storage tank and an air compressor. The air inlet pipeline of the air storage tank is connected to the air compressor, and the air outlet pipeline of the air storage tank is connected to the controller of each wave-making module.

[0020] The present invention will be further described below with reference to specific embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the protection scope of the present invention.

[0021] Example:

[0022] like Figure 1 As shown, a back-dry type rocker synchronous belt wave generator includes a fixed frame 1 and wave-generating modules 2 disposed on the fixed frame 1. Several wave-generating modules 2 are spaced apart on the fixed frame 1. Each wave-generating module 2 includes a rocker 3, an arc-shaped transmission frame 4, a drive unit 5, a synchronous belt 6, and an air spring 7. The upper part of the rocker 3 is connected to the arc-shaped transmission frame 4, the middle part of the rocker 3 is connected to the air spring 7, and the bottom of the rocker 3 is connected to the fixed frame 1. The air spring 7 is connected to a controller 8, which is used to set a constant pressure for the air spring 7, thereby providing water pressure and the thrust required for wave generation to the rocker 3. The drive unit 5 drives the synchronous belt 6 to move the arc-shaped transmission frame 4, thereby moving the rocker 3 connected to the arc-shaped transmission frame 4.

[0023] Preferably, it also includes an air storage tank 9 and an air compressor 10. The air inlet pipe 11 of the air storage tank 9 is connected to the air compressor 10, and the air outlet pipe 12 of the air storage tank 9 is connected to the controller 8 of each wave-generating module 2.

[0024] Specifically, the function of the air compressor 10 is to inflate the air reservoir 9 to maintain a certain pressure inside the air reservoir 9. In addition to storing high-pressure gas, the most important function of the air reservoir 9 is to inflate the air spring 7.

[0025] More specifically, because the air compressor 10 produces some noise when it is working, and frequent operation will also shorten the service life of the air compressor 10, the air compressor 10 first fills the air storage tank 9 with gas. After the air storage tank 9 reaches a certain air pressure, the air compressor 10 stops working, effectively reducing noise and extending the service life of the air compressor 10.

[0026] Preferably, the air spring 7 includes an air bag 13, a transmission component 14, and an inlet / outlet air pipe 15. One end of the transmission component 14 is connected to the rocker plate 3, and the other end of the transmission component 14 is connected to the air bag 13. The air bag 13 is connected to the controller 8 through the inlet / outlet air pipe 15.

[0027] Specifically, the air spring 7 provides the thrust required for wave generation by balancing water pressure with air pressure, and controls the inflation and deflation of the airbag 13 by the controller 8, thereby realizing the adjustment of the swing amplitude (angle) of the rocker 3.

[0028] Preferably, the controller 8 is equipped with a pressure sensor (not shown in the figure), which is used to monitor the attitude of the rocker 3.

[0029] Specifically, the pressure sensor is used to monitor the attitude of the rocker 3 and feed back the current state of the rocker 3 to the controller 8.

[0030] Preferably, the arc-shaped transmission frame 4 is connected to a support rod 16. One end of the arc-shaped transmission frame 4 is a fixed end 17, and the other end of the arc-shaped transmission frame 4 is a free end 18. The fixed end 17 is connected to the upper part of the rocker plate 3. One end of the support rod 16 is connected to the arc-shaped transmission frame 4, and the other end of the support rod 16 is connected to the lower part of the rocker plate 3.

[0031] Specifically, in this embodiment, the connection position between the support rod 16 and the arc-shaped transmission frame 4 is close to the free end 18 of the arc-shaped transmission frame 4.

[0032] Preferably, the drive unit 5 is fixedly mounted on the fixed frame 1. The drive unit 5 includes a drive motor 19, a synchronous pulley 20, a first tension pulley 21, and a second tension pulley 22. The output end of the drive motor 19 is connected to the synchronous pulley 20 for transmission. The synchronous belt 6 is wound around the synchronous pulley 20. One end of the synchronous belt 6 passes through the first tension pulley 21 and is connected to the free end 18 of the arc-shaped transmission frame 4. The other end of the synchronous belt 6 passes through the second tension pulley 22 and is connected to the fixed end 17 of the arc-shaped transmission frame 4.

[0033] Specifically, the synchronous belt 6 is flat and elongated, with teeth on one side and a smooth surface on the other. The teeth on the outer periphery of the synchronous pulley 20 mesh with the teeth of the synchronous belt 6 to achieve synchronous transmission. The first tension pulley 21 and the second tension pulley 22 are in contact with the smooth surface of the synchronous belt 6 to provide tensioning and guidance.

[0034] Preferably, a hinge seat 23 is provided on the bottom of the fixed frame 1, and a hinge shaft 24 is rotatably provided on the hinge seat 23. A hinge connecting frame 25 is provided on the bottom of the rocker plate 3, and the hinge connecting frame 25 is rotatably provided on the hinge shaft 24.

[0035] Specifically, the bottom of the support rod 16 is mounted on the hinged connecting frame 25.

[0036] Preferably, a force sensor (not shown in the figure) is provided on the rocker plate 3, which is used for wave feedback simulation.

[0037] Furthermore, the force sensor is located at the water level line of the rocker wave generator.

[0038] In practice, the inflation and deflation process of the air spring 7 is as follows: When the wave generator needs to generate waves, the controller 8 directly inflates the air spring 7 by controlling the air storage tank 9, instead of directly pressurizing the air spring 7 through the air compressor 10. The controller 8 sets a constant pressure for the air spring 7, providing water pressure and the thrust required for wave generation to the rocker plate 3. The drive unit 5 provides pressure to overcome the air spring 7 and pulls the rocker plate 3 back. During the process of providing and releasing pressure, the rocker plate 3 reciprocates. When no experiments are conducted for a long time, the air spring 7 deflates and rests against the fixed frame 1. The deflation process of the air spring 7 is relatively simple, relying on water pressure to expel the gas from the air spring 7.

[0039] In summary, this utility model has the following advantages:

[0040] (1) Good wave simulation effect: It can accurately simulate the shape, period and wave height changes of natural waves, making the simulated waves similar to actual ocean waves in terms of mechanical properties and statistical characteristics, providing reliable experimental conditions for marine engineering research, ship testing and other activities.

[0041] (2) High efficiency in deep water: In deep water environments, some single-sided wave generators, such as rocker wave generators, have higher wave generation efficiency and can better generate ideal waves in deeper waters.

[0042] (3) Small footprint: The wave generation direction is relatively simple, and it does not need to reserve a large space in multiple directions like a multi-directional wave generator. Therefore, it occupies a relatively small space in the laboratory or specific place.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
