Description

Technical Field

[0001] The present invention relates to the technical field of wave simulation equipment, and in particular to a multi-dimensional intelligent wave-making water tank and a flow field measurement system. Background Art

[0002] The wind, wave and current flume is a laboratory test equipment that simulates the marine environment. It is mainly used for model testing and testing of marine engineering and marine equipment. The wind, wave and current flume can conduct tests such as wind resistance and wave resistance. By simulating real marine conditions, it can observe and record data of the scaled model, and conduct environmental simulation analysis based on the data, providing strong data support for actual production and construction.

[0003] The existing wind and wave water tank, wind turbine mainly driven by motor, high-power axial flow water pump, push plate wave maker, wave-breaking plate, experimental water tank and control system are grouped together. It is also equipped with slide rails, XY trailers and cranes, which can carry various measuring equipment according to experimental needs. However, the existing wave-making equipment uses servo motors and complex mechanical transmission equipment, which makes the equipment expensive, difficult to maintain and requires a large area of space. This leads to a high threshold for experiments in the field of ship and ocean engineering. Ordinary researchers, students and small scientific research institutions are unable to carry out relevant experimental research. The industry urgently needs miniaturized wave-making pools. Compared with the vast ocean environment, the size of the pool is very limited. On the one hand, the waves generated by the existing miniaturized experimental wave-making device will be reflected when they reach the boundary. The reciprocating cycle will generate multiple reflected waves, which will "pollute" the target wave field, causing the wave field to be disordered, affecting the accuracy and reliability of the experiment, and leading to experimental failure. On the other hand, the commonly used components of the existing small wave-making devices are wave sensors, but in actual use, the accuracy of the initial zero position of the wave sensor cannot be maintained, and long-term measurement will cause zero drift problems.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the Invention

[0013] The present invention also provides a multi-dimensional intelligent wave-making flume flow field measurement system, comprising a parameter acquisition unit, a data acquisition unit, a flow field analysis unit, a parameter correction unit and a general control unit;

[0014] The parameter acquisition unit is used to obtain wave-making requirements, which include wave height, wave pressure, and wave period, obtain equipment operating parameters based on the wave-making requirements, which include the output power of the hydraulic pump, the output power of the servo motor, and the output power of the rotary motor, and send the equipment operating parameters to the main control unit;

[0015] The data acquisition unit is used to acquire wave data in the water tank through a sensor group, wherein the sensor group includes a capacitive wave height measurement sensor, a resistive wave measurement system and a micro point pressure sensor, and sends the wave data to the flow field analysis unit;

[0016] The flow field analysis unit is used to obtain and process wave data, including wave height data collected by a capacitive wave height measurement sensor, wave period collected by a resistive wave measurement system, and wave pressure data collected by a micro-point pressure sensor.

At the same time, it obtains the updated optimization parameters to adjust the output power of the hydraulic pump, the output power of the servo motor and the output power of the rotating motor again to further optimize the wave-making simulation process.

[0019] Furthermore, the specific process of optimizing the equipment operating parameters according to the evaluation results to obtain updated optimized parameters is as follows:

During the simulation process, define appropriate boundary conditions in the simulation area. After running the simulation, the CFD software can output the time-varying wave data and generate several dynamic wave simulation diagrams using the software's built-in graphics tools.

[0025] If the wave assessment coefficient Wi is less than Wmin or greater than Wmax, the assessment result is that the simulation fails to meet the standards;

[0026] S6. After obtaining the simulation results that do not meet the standards, obtain the ideal wave curve and the dynamic wave curve again, and optimize the equipment operating parameters according to the curve trends on the evaluation nodes.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. This multi-dimensional intelligent wave-making tank uses a hydraulic pump to power the hydraulic push rod, which drives the movable sleeve to move vertically up and down, and then drives the wave-making plate to move up and down in the tank to form waves. The main control unit controls the servo motor to rotate the ball screw, and the ball screw drives the slide to move along the horizontal track, thereby driving the wave-making plate to move. At the same time, the suction pump is used to inflate the expansion bladder, so that the expansion bladder expands and fills the gaps between the wave-making plates. By changing the overall size of the wave-making plate, the intensity and height of the waves can be changed to meet different wave simulation requirements.

[0029] 2. In this multi-dimensional intelligent wave-making tank, when the waves generated in the tank reach the edge of the tank, they first come into contact with the wave-breaking columns to eliminate the waves, and then flow downward along the wave-breaking slope blocks to weaken the wave trend. Among the two adjacent wave-breaking slope blocks, one wave-breaking slope block is fixed to the inner wall of the tank, and the other wave-breaking slope block is movably connected to the inner wall of the tank. Therefore, according to the wave simulation requirements, the main control unit can control the rotation motor to drive the hinge shaft to rotate, and then pull the hinge to drive the arc plate to move along the sliding long groove, thereby changing the distance between the two adjacent wave-breaking slope blocks, thereby adjusting the wave breaking effect, so that it cooperates with the wave-making mechanism to form different wave simulation requirements in the tank.

[0030] 4. The flow field measurement system of the multi-dimensional intelligent wave-making flume obtains equipment operating parameters according to wave-making requirements, realizes the wave-making simulation process, obtains wave data in the flume through the sensor group, obtains several dynamic wave simulation diagrams based on the wave data, and generates ideal wave representation diagrams according to the wave-making requirements. The wave evaluation coefficient is calculated based on the ideal wave representation diagram and several dynamic wave simulation diagrams, and the equipment operating parameters are optimized according to the evaluation results to obtain updated optimized parameters, further optimizing the wave-making simulation process, so that the wave-making effect is more inclined to the wave-making requirements.

Several wave-breaking mechanisms are connected to the driving mechanism, and several wave-breaking mechanisms are fixedly provided on the inner wall of the water tank 1 and fixedly connected to the measuring assembly.

[0039] The wave-making mechanism includes a movable sleeve 6 and a wave-making component. The movable sleeve 6 is fixed to the outer surface of the fixed flange 4. The outer surface of the movable sleeve 6 is fixed with a first ring 7 and a second ring 8. Several wave-making components are fixed between the first ring 7 and the second ring 8.

[0040] The wave-making component includes a wave-making plate 13 and an expansion bag 27. A horizontal track 9 is fixedly provided on the top surface of the second ring 8, and a servo motor 10 is fixedly provided on the inner wall of the horizontal track 9. The output end of the servo motor 10 is connected to a ball screw 11, and a slide 12 is movably connected to the inner wall of the horizontal track 9. The slide 12 is movably sleeved on the outer surface of the ball screw 11. The wave-making plate 13 is fixed on the top surface of the slide 12, and the expansion bag 27 is fixed on the outer two side surfaces of the wave-making plate 13. A limiting long groove 14 is fixed on the bottom surface of the first ring 7, and a limiting block 15 is commonly connected between the limiting long groove 14 and the wave-making plate 13.

[0041] A suction pump 16 is fixedly provided on one side surface of the wave-making plate 13 , and a suction pipe 17 is commonly connected between the outer surface of the output end of the suction pump 16 and the expansion bag 27 .

[0042] The driving mechanism includes a rotary motor 18 and a hinge 20 . The rotary motor 18 is fixed to the outer surface of the water tank 1 . A hinge shaft 19 is fixed to the output end of the rotary motor 18 . The hinge 20 is movably wound around the outer surface of the hinge shaft 19 .

[0043] The wave-breaking mechanism includes a wave-breaking slope block 21 and a curved plate 22. The wave-breaking slope block 21 is connected to the inner wall of the water tank 1. The curved plate 22 is fixed to the top surface of the wave-breaking slope block 21. A number of wave-breaking columns 23 are evenly distributed on the top surface of the curved plate 22. The end surface of the hinge 20 is fixedly connected to the outer surface of the curved plate 22.

[0044] The measuring assembly includes a floating block 25 and a traction rope 24. One end of the traction rope 24 is connected to the outer surface of the wave-breaking slope block 21. The floating block 25 is fixedly connected to the outer surface of the traction rope 24. A sensor group 26 is fixedly provided on the top surface of the floating block 25.

[0045] The working principle is as follows: the hydraulic pump 2 provides power to the hydraulic push rod 3, which drives the movable sleeve 6 to move vertically up and down, and then drives the wave-making plate 13 to move up and down in the water tank 1. At this time, the water surface will be pushed open to form a wave crest. At the same time, the water in the pool will be affected by the thrust of the wave plate, and begin to fluctuate, forming waves.

[0046] According to the requirements of wave simulation, the main control unit controls the servo motor 10 to drive the ball screw 11 to rotate, and the ball screw 11 drives the slide 12 to move along the horizontal track 9, thereby driving the wave-making plate 13 to move. At the same time, the suction pump 16 inflates the expansion bag 27, so that the expansion bag 27 expands and fills the gap between the wave-making plates 13. By changing the overall size of the wave-making plates 13, the intensity and height of the waves can be changed to meet different wave simulation requirements.

[0047] When the waves generated in the water tank 1 reach the edge of the water tank 1, they first contact the wave-breaking columns 23 to eliminate the waves, and then flow downward along the wave-breaking slope blocks 21 to weaken the wave trend. Among the two adjacent wave-breaking slope blocks 21, one wave-breaking slope block 21 is fixed to the inner wall of the water tank 1, and the other wave-breaking slope block 21 is movably connected to the inner wall of the water tank 1. Therefore, according to the wave simulation requirements, the main control unit can control the rotating motor 18 to drive the hinge shaft 19 to rotate, and then pull the hinge 20 to drive the arc plate 22 to move along the sliding long groove 5, thereby changing the distance between the two adjacent wave-breaking slope blocks 21, thereby adjusting the wave breaking effect, so that it cooperates with the wave-making mechanism to form different wave simulation requirements in the water tank 1.

[0053] The parameter correction unit is used to obtain a preset evaluation range, determine the evaluation coefficient according to the evaluation range to obtain an evaluation result, and optimize the equipment operating parameters according to the evaluation result to obtain updated optimized parameters and send them to the main control unit;

[0054] The main control unit is used to obtain the equipment operating parameters and adjust the output power of the hydraulic pump 2, the output power of the servo motor 10 and the output power of the rotating motor 18 accordingly to realize the wave-making simulation process. At the same time, it obtains the updated optimization parameters to adjust the output power of the hydraulic pump 2, the output power of the servo motor 10 and the output power of the rotating motor 18 again to further optimize the wave-making simulation process.

[0055] The specific process of optimizing the equipment operating parameters according to the evaluation results to obtain updated optimized parameters is as follows:

[0056] S1. Obtain wave data, then import real-time wave height data, wave period, and wave pressure data into CFD software. During the simulation process, define appropriate boundary conditions in the simulation area.

The parameter correction unit is used to obtain a preset evaluation range, determine the evaluation coefficient according to the evaluation range to obtain an evaluation result, and optimize the equipment operating parameters according to the evaluation result to obtain updated optimized parameters and send them to the main control unit; The total control unit is used to obtain the equipment operating parameters and adjust the output power of the hydraulic pump (2), the output power of the servo motor (10) and the output power of the rotary motor (18) accordingly, thereby realizing the wave-making simulation process, and simultaneously obtain updated optimization parameters to adjust the output power of the hydraulic pump (2), the output power of the servo motor (10) and the output power of the rotary motor (18) again, thereby further optimizing the wave-making simulation process.

The flow field measurement system of the multi-dimensional intelligent wave-making flume according to claim 5 is characterized in that: The specific process of obtaining the updated optimization parameters is as follows: S1. Obtain wave data, then import real-time wave height data, wave period, and wave pressure data into CFD software. During the simulation process, define appropriate boundary conditions in the simulation area. After the simulation, the CFD software can output the time-varying wave data and generate several dynamic wave simulation diagrams using the software's built-in graphics tools. S2. Obtain wave-making requirements, including wave height, wave pressure, and wave period. Similarly, input the wave-making requirements into the CFD software to generate several ideal wave representation diagrams. S3, grayscale processing is performed on the ideal wave representation image and the plurality of dynamic wave simulation images to obtain an ideal grayscale image and a simulated grayscale image, and feature extraction is performed on the ideal grayscale image and the simulated grayscale image respectively to obtain an ideal wave curve and a dynamic wave curve; S4. Establish a standard coordinate system, and integrate the ideal wave curve and the dynamic wave curve into the standard coordinate system. Mark the evaluation node on the abscissa of the standard coordinate system, obtain the curve characteristics at the evaluation node, which include the slope Ki, extreme value di, and period Ti of the ideal wave curve and the slope Kj, extreme value dj, and period Tj of the dynamic wave curve. Calculate the wave evaluation coefficient Wi according to the following formula: , where e1, e2 and e3 are preset proportional coefficients, where i = 1, 2, 3, …, n, and the wave assessment coefficient is used to feedback the degree of deviation between the real-time wave data and the wave-making requirements; S5. Obtain a preset assessment range (Wmin, Wmax). If the wave assessment coefficient Wi is greater than or equal to Wmin and less than or equal to Wmax, the assessment result is that the simulation meets the standards. If the wave assessment coefficient Wi is less than Wmin or greater than Wmax, the assessment result is that the simulation fails to meet the standards; S6. After obtaining the simulation results that do not meet the standards, obtain the ideal wave curve and the dynamic wave curve again, and optimize the equipment operating parameters according to the curve trends on the evaluation nodes.
