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 tests and testing of marine engineering and marine equipment. The wind, wave and current flume can conduct tests such as wind resistance and wind and wave resistance. By simulating real marine conditions, data observation and recording of the year-on-year scaling model are carried out, and environmental simulation analysis is carried out based on the data, providing strong data support for actual production and construction. The existing wind and wave water tank, wind turbines mainly driven by motors, high-power axial flow water pumps, push-plate wave makers, wave-breaking plates, experimental water tanks and control system groups. 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 ​​​​site, which leads to a high threshold for experiments in the field of shipbuilding and marine engineering. Ordinary researchers, students and small scientific research institutions cannot carry out related experimental research. The industry is in urgent need of 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 device 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; In view of the above technical defects, a solution is now proposed.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This multi-dimensional intelligent wave-making tank uses a hydraulic pump to provide power to the hydraulic push rod, so that the hydraulic push rod 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 servo motor is controlled by the main control unit to drive the ball screw to rotate, 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 bag, so that the expansion bag expands and fills the gap between the wave-making plates. The intensity and height of the wave are changed by changing the overall size of the wave-making plate to meet different wave simulation requirements.

[0014] 2. In this multi-dimensional intelligent wave-making water tank, when the waves generated in the water tank reach the edge of the water tank, they first contact 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 water tank, and the other wave-breaking slope block is movably connected to the inner wall of the water tank. Therefore, according to the wave simulation requirements, the main control unit can control the rotating 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 water tank.

[0015] 4.

[0027] The specific process of optimizing the equipment operating parameters according to the evaluation results to obtain updated optimized parameters is as follows: S1. Obtain wave data, and then import the real-time wave height data, wave period and wave pressure data into the CFD software. During the simulation process of the CFD software, define appropriate boundary conditions in the simulation area.

During the simulation process of the CFD software, define appropriate boundary conditions in the simulation area. After running the simulation, the CFD software can output the time-varying data of the waves, and generate several dynamic wave simulation diagrams through the graphics tools provided by the software. S2. Obtain wave-making requirements, including wave height, wave pressure and wave period, and input the wave-making requirements into the CFD software to generate several ideal wave representation diagrams; S3, gray-processing the ideal wave representation image and several dynamic wave simulation images to obtain an ideal gray-scale image and a simulated gray-scale image, and performing feature extraction on the ideal gray-scale image and the simulated gray-scale image to obtain an ideal wave curve and a dynamic wave curve; S4. Establish a standard coordinate system, integrate the ideal wave curve and the dynamic wave curve into the standard coordinate system, mark the evaluation node on the horizontal axis of the standard coordinate system, obtain the curve characteristics on the evaluation node, the curve characteristics 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, and 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 demand; S5. Obtain a preset evaluation range (Wmin, Wmax). If the wave evaluation coefficient Wi is greater than or equal to Wmin and less than or equal to Wmax, the evaluation result is that the simulation meets the standard; 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 standard; 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.
