DETAILED DESCRIPTION

[0016] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0017] Example: An oil spill dispersant experimental device, see Figure 1 , including a test water tank 1, a wave generating device 2, a water flow generating device 3, and a wind generating device 4. The wave generating device 2 and the water flow generating device 3 are both arranged in the test water tank 1, and the wind generating device 4 is connected to one end of the test water tank 1. The test water tank 1 in this embodiment is in the shape of a long strip. Liquid is stored in the test water tank 1, and the liquid can be seawater or fresh water. The choice of seawater or fresh water depends on the experimental needs. For example, to simulate the environment of an ocean, a river, or a lake, the experimental equipment research and development team found that it is necessary to construct a composite fluid environment that can simultaneously simulate wave motion, overall water flow, and local turbulence. Traditional equipment mostly uses a single wave-making or flow-making method, which makes it difficult to achieve the coupling effect of different flow modes. By analyzing the characteristics of marine fluid dynamics, a design idea of ​​independently controlling the overall flow and local disturbances is proposed, which can not only simulate large-scale water movements such as ocean currents, but also reproduce local turbulence effects such as ship wakes.

[0018] See also Figure 2 The wave generating device 2 is arranged at one end of the test water tank 1, and includes a wave-making push plate 21 and a wave-making control component 22 for driving the wave-making push plate 21 to move. The wave-making push component in this embodiment adopts a ball screw pair including a screw, a ball nut and a driving motor for driving the screw to rotate, but the wave-making push component can also adopt a linear motion mechanism such as an electric push rod or a linear module. The wave-making push component can be used to drive the wave-making push plate 21 to move, so that the wave-making push plate 21 is used to beat the liquid in the test water tank 1 to form waves. By changing the moving speed and frequency of the wave-making push plate 21 driven by the wave-making push assembly, waves of different shapes can be generated, such as regular waves, irregular waves or specific spectrum waves. The waves generated by the wave generating device 2 in the test water tank 1 move from one end of the test water tank 1 to the other end. A wave-breaking block 14 is provided at the end of the test water tank 1 away from the wave generating device 2. The wave-breaking block 14 is arranged with an inclined slope toward the end of the wave generating device 2. The inclined design of the wave-breaking block 14 can effectively reflect and dissipate wave energy, thereby preventing wave rebound from interfering with the experiment.

[0019] The water flow generating device 3 includes an overall flow generating component 31 and a drag flow generating component 32. The overall flow generating component 31 includes a circulation pipeline 311, a circulation water pump 312, a water inlet 313 and a drain 314 arranged in the circulation pipeline 311.

The two ends of the circulation water pipe are connected at the water inlet 313 and the drain 314 respectively. Through the circulation water pump 312, the liquid enters the test water tank 1 from the water inlet 313. A water flow is formed in the test water tank 1 and then re-enters the circulation pipe through the drain port 314. In this embodiment, the water inlet 313 and the wave generating device 2 are located on the same side of the test water tank 1. The circulation pipe 311 is equipped with a chiller. The liquid in the circulation pipe 311 can enter the chiller. The temperature of the liquid in the circulation pipe 311 can be controlled by the chiller, and the liquid in the test water tank 1 can be controlled to have different temperatures to simulate the influence of different climatic conditions on the existing dispersion effect, thereby increasing the diversity of the experiment.

[0020] The wave generating device 2 and the water flow generating device 3 can accurately reproduce the synergistic effect of waves, overall water flow and local turbulence in the marine environment, providing a real experimental environment for evaluating the diffusion inhibition effect of oil spill dispersants under different sea conditions. Experimenters can adjust the motion parameters, overall flow velocity and jet intensity of the wave-making push plate 21 to systematically study the influence of fluid dynamic parameters on dispersant performance, significantly improving the correlation between experimental data and practical applications.

[0024] See also Figure 2 and Figure 4The dragging flow-making assembly 32 includes a first translation assembly 321, a dragging platform 322 and a jet nozzle 323. The dragging platform 322 is controlled by the first translation assembly 321. The first translation assembly 321 includes a linear slide rail, a slider that slides with the linear slide rail, a motor, and a transmission belt controlled by the rotation of the motor. A transmission pulley is keyed on the output shaft of the motor. The motor is arranged at one end of the test water tank 1, and a driven pulley that cooperates with the transmission belt is pivotally provided at the other end of the test water tank 1. The two ends of the transmission belt are respectively sleeved on the transmission pulley and the driven pulley. The dragging platform 322 is fixedly connected to the slider by screws, and the dragging platform 322 is fixedly connected to the clamping block. The dragging platform 322 is fixedly connected to the transmission belt through the clamping block. When the output shaft of the transmission motor drives the transmission pulley to rotate, and then drives the transmission belt to rotate, the rotation of the transmission belt drives the dragging platform 322 to move along the linear slide rail.

[0025] A sensor mounting plate is provided on the dragging platform 322, and the sensor mounting plate can be used to install the following various acquisition modules. The ejector 323 is provided on the dragging platform 322, and the ejector 323 moves synchronously with the dragging platform 322. The ejector 323 is connected to a storage tank for storing liquid.

The transfer platform drives the industrial camera 12 to move back and forth. The industrial camera 12 shoots the scene in the observation window 11, automatically shoots the experimental process, and records the dynamic changes of the existing diffusion.

[0027] When simulating oil spill diffusion in the test water tank 1, the industrial camera 12 moves along the length of the water tank through the third translation component 13, and can continuously and dynamically shoot the oil film diffusion process on the water surface. The extended layout of the observation window matches the movement path of the camera, so that the camera always maintains panoramic coverage of the interior of the water tank during movement. When it is necessary to focus on a specific section, the third translation component can control the camera to stop at the target position for fixed-point shooting, such as capturing the breaking effect of waves on the oil film in the wave-making device area, or recording the stretching state of the oil film downstream of the flow-making device, realizing full visual monitoring of the oil spill diffuser performance test process, and solving the problem of incomplete test data caused by the limited observation range of traditional equipment. The camera movement trajectory is adapted to the linear extension characteristics of the test water tank, ensuring continuous capture of the oil film diffusion boundary during the experiment, and providing complete image data support for analyzing the effect of the diffuser under different flow field conditions.

The wave-making control unit includes a wave-making database storage and a wave-making control subunit. The wave-making database stores a number of wave information. The wave-making control subunit is used to generate corresponding wave-making signals according to the wave information selected by the user and send them to the overall water flow generating device 3. The overall water flow generating device 3 matches the wave information in the wave-making data according to different wave-making signals to generate waves of corresponding shapes.

[0029] The acquisition module includes a wave acquisition unit, a jet acquisition unit and a wind generation acquisition unit. The wave generation acquisition unit is used to acquire the shape of waves in the test water tank 1 and generate waveform information. The jet acquisition unit is used to acquire the flow rate of the liquid in the test water tank 1 and generate flow rate information. The wind generation acquisition unit is used to acquire the wind speed in the test water tank 1 and generate wind speed information. The display module is used to display waveform information, flow rate information, wind speed information and the image captured by the industrial camera 12. The control module also includes a wave cancellation control unit, which includes a wave cancellation command generation subunit and an auxiliary wave cancellation control subunit.

[0030] The wave collection unit adopts a wave monitoring buoy with a built-in sensor that can provide real-time feedback on parameters such as wave height and wavelength. It can be used to collect regular waves or irregular waves. The wave-breaking command generation subunit is connected to the wave-making collection unit. When the waveform information generated by the wave-making collection unit is inconsistent with the wave information stored in the wave-making database, the wave-breaking command generation subunit generates a stop signal. The wave-making control component 22 drives the wave-making push plate 21 to stop moving according to the stop signal, and the auxiliary wave-breaking control subunit drives the ejector 323 to a water-spraying state according to the stop signal, and the jet direction of the ejector 323 is toward the direction of the wave-making push plate 21, thereby accelerating the elimination of waves in the test water tank 1.

[0031] The wave-generating database storage refers to a database that stores characteristic parameters of wave morphology. It can be implemented using a relational database or a time-series database and is used to match the user-selected wave type with the actual wave morphology generated by the device. The wave-generating control subunit is a logic module that parses user input and generates control signals based on a preset algorithm. Specifically, it can be implemented using a PLC controller or embedded system to drive the wave-generating push plate 21 to produce the target waveform. Circulating water pump 312 flow control refers to adjusting the pump speed through a frequency converter to change the inlet and outlet water flow rates. Specifically, it can be implemented using a PID closed-loop control algorithm to maintain the stability of liquid flow in the water tank. The air volume control subunit is an electronic speed control device that adjusts the speed of the fan 41. It can be implemented using a continuously variable speed motor or servo drive to precisely control the airflow intensity within the wind tunnel test tube 43.

[0032] When the system is running, the user selects the target wave parameters through the human-machine interface. The wave-making control unit calls the database to match the corresponding control curve and drives the wave-making push plate 21 to generate a specific waveform. At the same time, the circulating water pump 312 maintains the overall water circulation in the water tank according to the set flow parameters. The dragging platform 322 drives the ejector 323 along a predetermined trajectory to generate local turbulence. The fan 41 in the wind tunnel test tube 43 adjusts the output according to the wind speed set value. The wind guide component 42 dynamically corrects the air outlet angle and height based on the collected real-time wind speed data. The wave shape is collected by the laser displacement sensor. The waveform contour is collected. The flow velocity sensor is arranged at the key position of the water tank to monitor the flow state. The wind speed sensor array is distributed in the wind tunnel test section 433 to measure the airflow parameters. All collected data is processed and synchronously displayed on the visualization terminal and superimposed with the oil film diffusion image captured by the camera for analysis.

[0033] In some specific embodiments, the wave breaking control unit can be configured as an automatic trigger mode. When it is detected that the waveform deviation exceeds a threshold, the wave-making action is immediately stopped and the ejector 323 is started to reversely spray and break the wave. The display interface can integrate a multi-window split-screen display function, for example, the real-time waveform curve and wind speed bar graph are displayed on the left, and the dynamic image of the oil film diffusion captured by the camera is played on the right.

[0034] Compared with existing technologies, traditional oil spill detection equipment only uses static water tanks for single parameter testing. This system, by integrating wave, current, and wind composite control modules, realizes the coordinated simulation of multiple elements of the marine environment. Existing technologies lack real-time data collection and feedback mechanisms. This solution constructs a closed-loop test environment through a multi-sensor array and a visual interface, significantly improving the controllability of the experiment.

[0035] This application can accurately simulate the complex fluid conditions of the marine environment and provide a reliable testing platform for the performance evaluation of different oil spill dispersants. The system realizes the simulation of the dynamic coupling of waves, water flow and wind force through multi-module collaborative control, solving the technical defects of traditional equipment that cannot reproduce the real marine environment. The real-time data acquisition and visualization functions make the experimental process observable and traceable, providing accurate data support for optimizing the dispersant formula.

[0036] When the wave shape generated by the wave-making push plate 21 deviates from the preset parameters during the experiment, the wave-breaking command generation subunit immediately sends a stop command to the wave-making control component 22, and synchronously triggers the start of the jet 323. After the jet 323 moves to the target position along the dragging platform 322, it sprays water at a specific angle toward the wave-making push plate 21 to form a reverse disturbance to offset the residual waves in the water tank. For example, when the waveform amplitude is detected to exceed the threshold, the jet 323 can be adjusted to the depth corresponding to the wave peak and valley under the drive of the second lifting component 324, and the water surface can be accelerated to calm down by adjusting the jet flow rate.

[0037] Traditional experimental equipment only relies on stopping the wave-making push plate 21 to achieve wave elimination, resulting in the long-term existence of residual waves that affect the accuracy of subsequent experiments. This solution uses a linked stopping mechanism and active jet wave elimination to quickly eliminate residual waves in the water tank after stopping wave generation, shortening the experimental environment recovery time and avoiding distortion of oil spill diffuser test data caused by residual waves.

[0038] This application effectively solves the problem of test errors caused by the inability of traditional detection equipment to eliminate residual waves in a timely manner. Through the active jet offset mechanism, it ensures that the fluid state in the water tank quickly returns to the baseline conditions before each experiment, significantly improving the stability and comparability of performance tests of different batches of oil spill dispersants.
