Description

Technical Field

[0001] The invention relates to the technical field of aquifer monitoring, and in particular to a wave-making simulation device for monitoring underground aquifers on islands and reefs. Background Art

[0002] Simulating and studying the changes in the amount of groundwater resources and groundwater environment on islands and reefs can help us understand the hydraulic balance and water volume of islands and reefs, and through artificial intervention facilities and systems, effectively intercept freshwater resources, increase freshwater utilization, conserve surface vegetation, and support the development and utilization of freshwater on the islands. In island and reef areas with small waves, it is necessary to set up artificial wave-making devices to observe the impact of seawater on the underground freshwater of islands and reefs. After the wave ends its impact on the beach and before the next wave arrives, the water on the beach will recede back into the ocean. The artificial wave-making equipment in the existing technology simply generates periodic forces to push the seawater toward the coast, and cannot fully utilize the energy of the seawater retreating from the beach into the ocean. When pushing the seawater toward the coast, the thrust may just encounter the retreat of the water on the beach, which will also weaken the impact of the seawater on the beach. In addition, the existing technology pushes the seawater toward the beach at fixed intervals, and the simulated waves are different from the irregular wave movement in the natural environment.

When the waves move toward the beach, they pass through the rear deflector and several of the front deflectors in sequence. The front deflector is rotatably connected to a bracket, the lower end of the bracket is connected to the lower deflector, the rear end of the lower deflector is provided with the rear end of the lower deflector, the rear end of the rear deflector is an arc-shaped structure with a concave surface facing the front deflector, the rear deflector is provided with the flow rate sensor, the flow rate sensor is connected to a controller by signal, and the controller is connected to the driving mechanism by signal; when the flow rate sensor detects that the waves are moving toward the coast, the controller controls the driving mechanism to drive the front deflector to rotate to a position where the upper end is above the water surface, and after a preset time, drives the front deflector to rotate to a position parallel to the lower deflector.

[0006] Furthermore, the driving mechanism includes a motor and a connecting rod, the connecting rod is rotatably connected to the plurality of front deflectors, and the output shaft of the motor is connected to the front deflectors.

[0007] Furthermore, the motor and the flow rate sensor are signal-connected to the controller, and the controller is electrically connected to the power supply device.

[0008] Furthermore, the motor is a waterproof motor.

[0009] Furthermore, an upper guide plate is provided above the lower guide plate, a water flow channel is formed between the upper guide plate and the lower guide plate, and a first through hole is provided on the upper guide plate below the front guide plate.

[0010] Furthermore, the power supply equipment includes a floating plate, a permanent magnet, a magnetic tube and a column. The floating plate floats on the water surface and is provided with a through hole in the middle. The magnetic tube passes through the through hole. The permanent magnet is provided around the through hole. An induction coil is provided in the magnetic tube. The column passes through the middle of the magnetic tube.

[0014] Furthermore, a filter is provided at the water inlet of the water push pump, and a friction pad is provided on the side of the balloon facing the column.

[0015] The beneficial effects of the present invention are:

[0016] As waves move away from the beach, they sequentially pass through the locations of the front and rear deflectors. When the front deflector rotates upward and tilts toward the beach, the water retreating from the beach is directed underwater by the front deflector. The water changes its direction along the rear deflector, ultimately moving toward the beach. After the front deflector rotates so that its upper end is above the water surface, the front, lower, and rear deflectors work together to guide the water. This prevents the retreating water from interacting with the returning water, thereby weakening the impact of the water on the beach. It also utilizes the kinetic energy of the water pushed away from the coast to propel the water toward the shore. This prevents the waves from being obstructed by the front deflector as they approach the beach, facilitating their impact. The frequency and amplitude of the waves generated by the present invention are not fixed, more closely resembling the motion of waves in a natural environment, resulting in a more realistic simulation.

DETAILED DESCRIPTION

[0022] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0023] Example 1

[0024] See also Figure 1A wave-making simulation device for monitoring underground aquifers on islands and reefs comprises a front deflector 1, a rear deflector 2, a lower deflector 3, a flow velocity sensor 4 and a driving mechanism 5. The front deflector 1 and the rear deflector 2 are located in a straight line and are arranged along the moving direction of the waves. When the waves move toward the beach, they pass through the rear deflector 2 and several of the front deflectors 1 in sequence. When the waves move in the direction of retreating from the beach, they pass through the positions of several of the front deflectors 1 and the rear deflectors 2 in sequence. The front deflector 1 is rotatably connected to a bracket 6, and the front deflector 1 rotates upward and tilts toward the beach. When the water moves in the direction of the beach, the seawater retreating from the beach is guided by the front deflector 1 and moves underwater. The lower end of the bracket 6 is connected to the lower deflector 3, so that the bracket 6 is fixed on the lower deflector 3, and the lower deflector 3 is located at the bottom of the front deflector 1 and the rear deflector 2. The rear end of the lower deflector 3 is provided with the rear deflector 2. The seawater moving along the lower deflector 3 will impact the rear deflector 2. The rear deflector 2 is an arc-shaped structure with the concave surface facing the front deflector 1, and finally causes the seawater to change its direction of movement along the rear deflector 2 and finally move toward the beach. The rear deflector 2 is provided with the flow velocity sensor 4, which can detect the direction of movement of the seawater. The flow velocity sensor 4 is connected to the controller 7 for signal transmission, and the flow velocity sensor 4 transmits the detected signal to the controller 7. The controller 7 is also signal-connected to the drive mechanism 5. When the flow rate sensor 4 detects waves moving toward the coast, the controller 7 controls the drive mechanism 5 to rotate the front deflector 1 to a position where its upper end is above the water surface. After the front deflector 1 rotates to a position where its upper end is above the water surface, the front deflector 1, lower deflector 3, and rear deflector 2 jointly divert the seawater. This, on the one hand, prevents the retreating seawater from interacting with the returning water, thereby weakening the impact of the seawater on the beach. On the other hand, it utilizes the kinetic energy of the seawater pushed away from the coast to propel the seawater toward the coast. After the front deflector tilts toward the coastline for a preset period of time, the drive mechanism 5 then drives the front deflector 1 to rotate to a position parallel to the lower deflector 3. This prevents the waves from being obstructed by the front deflector 1 as they rush toward the beach, thereby facilitating the waves' impact on the beach. The frequency and amplitude of the waves generated by the present invention are not fixed, and are closer to the movement of waves in a natural environment, resulting in a more realistic simulation.

[0025] Specifically, the drive mechanism 5 includes a motor 8 and a connecting rod 9. Several of the front deflectors 1 are interconnected via the connecting rod 9, and the output shaft of the motor 8 is connected to the front deflectors 1. The motor 8 is fixed to the bracket 6. When the output shaft of the motor 8 rotates, the front deflectors 1 rotate. Since the front deflectors 1 are interconnected via the connecting rod 9, they can drive each other, ultimately causing all of the front deflectors 1 to rotate so that their upper ends extend out of the water. This prevents the receding seawater from interacting with the returning water, thereby weakening the impact of the seawater on the beach. Furthermore, the kinetic energy of the seawater pushed away from the coast can be used to push the seawater toward the coast.

[0026] Specifically, the motor 8 and flow sensor 4 are signal-connected to the controller 7, which is electrically connected to a power supply. The flow sensor 4 transmits collected information to the controller 7, which controls the operation of the motor 8 based on the information transmitted by the flow sensor 4. The present invention supplies power to the aforementioned devices via the power supply. The flow sensor 4 monitors the flow velocity of the seawater in real time, enabling automated control and facilitating detection and utilization of seawater energy.

[0027] Specifically, the motor 8 is a waterproof motor 8 , which increases the service life of the motor 8 .

[0028] Specifically, an upper guide plate 24 is provided above the lower guide plate 3. A water flow channel is formed between the upper guide plate 24 and the lower guide plate 3. The upper guide plate 24 is provided with a first through hole 25 below the front guide plate 1. After being guided by the front guide plate 1, the seawater retreating from the beach passes through the first through hole 25 into the water flow channel and then moves along the water flow channel to the rear guide plate 2. The upper guide plate 24 concentrates the flow of seawater, which is conducive to utilizing the kinetic energy of the seawater.

[0029] Example 2

[0030] See also Figures 2-3This embodiment differs from the first embodiment in that the power supply device includes a floating plate 10, a permanent magnet 11, a magnetic tube 12, and a column 13. The floating plate 10 floats on the water surface and has a through hole 14 in its center. As the sea surface fluctuates, it drives the floating plate 10 up and down. The magnetic tube 12 passes through the through hole 14, and as the floating plate 10 moves up and down, the magnetic tube 12 remains in the through hole 14. The upper end of the magnetic tube 12 is always above the water surface. The through hole 14 is surrounded by the permanent magnet 11, which is fixed to the floating plate 10 and moves up and down with the floating plate 10. The magnetic tube 12 contains an induction coil 15. As the floating plate 10 moves up and down, it drives the permanent magnet 11 up and down, cutting the magnetic flux lines of the induction coil 15, thereby generating an induced electromotive force that generates electricity. This generated electricity is rectified and stabilized, then charged into a battery (not shown). The battery then powers the controller 7, the motor 8, and the flow rate sensor 4. The column 13 passes through the middle of the magnetic tube 12. When the tide rises or falls, the sea level rises, and when waves arrive, the floating plate 10 moves up and down. The permanent magnet 11 is almost synchronized with the surface fluctuations of the waves, improving power generation efficiency. Because the top and bottom of the magnetic tube 12 are both provided with limit blocks 16, the lower end of the column 13 is fixed underwater. When the floating plate 10 rises above the position of the limit blocks 16, it will drive the magnetic tube 12 up and down, ensuring that after the water level rises, the waves drive the floating plate 10 up and down to always cut the magnetic flux lines. Similarly, when the floating plate 10 descends above the position of the limit blocks 16, it will drive the magnetic tube 12 up and down, ensuring that after the water level drops, the waves drive the floating plate 10 up and down to always cut the magnetic flux lines, fully utilizing the wave energy of the up and down movement of the waves and improving power generation efficiency.

[0031] Specifically, the magnetic tube 12 includes an inner tube 17, an outer tube 18 and a tube cover 19. The inner tube 17 is arranged in the outer tube 18. The inner tube 17 and the outer tube 18 play a protective role. The tube cover 19 seals both ends of the inner tube 17 and the outer tube 18 to prevent seawater from entering the space between the inner tube 17 and the outer tube 18. A closed cavity is formed between the inner tube 17 and the outer tube 18. The induction coil 15 is arranged in the cavity to prevent the coil from being corroded by seawater. The inner wall of the inner tube 17 and the outer wall of the outer tube 18 are both in contact with seawater, which is also conducive to heat dissipation.

[0032] Specifically, the lower deflector 3 has a second through hole 26 at one end near the rear deflector 2, and a water pump 27 is installed in the second through hole 26. The water pump 27 is connected to the controller 7 by signal, and the operation of the water pump 27 is controlled by the controller 7. When the flow rate sensor 4 detects that the waves are moving to the position of the rear deflector 2, the water pump 27 is activated to pump seawater 22 to the position of the rear deflector 2. Under the action of the rear deflector 2, the seawater changes direction and moves toward the beach, thereby boosting the waves and promoting the waves to impact the beach.

[0033] Optionally, the inner wall of the inner tube 17 is provided with a raised balloon 20, which contacts the column 13 and uses the friction between the balloon 20 and the column 13 to fix the height position of the magnetic tube 12. The balloon 20 is connected to a water pipe 21, and the water pipe 21 is connected to the top of a water pump 22. The water pipe is provided with an electromagnetic valve connected to a controller signal. When the electromagnetic valve is opened, when the water pump is working, seawater is pushed into the water pipe, and water is filled into the balloon 20 through the water pipe to adjust the friction between the balloon 20 and the column 13. Preferably, the water pump is connected to the controller 7 signal, and the controller 7 is used to control the operation of the water pump. Closing the electromagnetic valve can prevent seawater from passing through the water pipe, thereby maintaining the friction between the balloon and the column.

[0034] Specifically, the water inlet of the water pump is provided with a filter 23, and the seawater is filtered through the filter 23 before being filled into the balloon 20. A friction pad (not shown) is provided on the side of the balloon 20 facing the column 13 to improve the wear resistance of the balloon 20.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
