In recent years, with the intensification of the global energy crisis and the continuous deepening of marine resource development, marine engineering technology, especially deep-sea engineering technology, has gradually attracted attention. With the increase in the depth of marine development, the challenges faced by marine engineering are becoming increasingly severe.

[0043] Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings.

[0044] Combination Figures 1 to 8 As shown, an embodiment of the present application provides a simulation system, including a water reservoir 10, a gate 13, an environmental simulation system 20, a measurement system 30 and a control system 40.

[0045] Combination Figure 1 The water reservoir 10 includes a side wall 12, a bottom wall 11 connected to the side wall 12, and a first accommodating chamber 100. The gate 13 is opened on the side wall 12 of the water reservoir 10. The bottom wall 11, the side wall 12 of the water reservoir 10, and the gate 13 in a closed state together enclose the first accommodating chamber 100.

[0046] The environmental simulation system 20 acts on the water and / or air contained in the first accommodating chamber 100 to simulate the sea condition. The measuring system 30 is used to monitor the parameter information of the reservoir 10 during the sea condition simulation process. The control system 40 is electrically connected to the gate 13, the environmental simulation system 20 and the measuring system 30. The control system 40 is used to control the gate 13 to be opened or closed according to the current sea condition simulation requirements, so that the first accommodating chamber 100 is connected to or closed from the external environment of the reservoir 10.

[0047] The control system 40 here has data processing and storage capabilities, and can process, store and analyze the large amount of data generated during the experiment in real time. Through the automated processing of data, the system can further generate an experimental report to provide data support for subsequent experimental analysis and result verification. The control system 40 adopts an open design, has good scalability and compatibility, and can be linked with other experimental equipment to provide more efficient operation support for complex experiments.

[0048] The simulation system provided by the embodiment of the present application is adopted, and the sea condition is simulated by the reservoir 10 and the environmental simulation system 20, and the real-time monitoring of the parameter information in the reservoir 10 during the sea condition simulation is realized by the measurement system 30 to obtain the simulated experimental results. In addition, the switch control of the gate 13 opened in the side wall 12 is performed by the control system 40. When the control system 40 controls the gate 13 to be closed, the first accommodating chamber 100 in the reservoir 10 is isolated from the external environment, and the reservoir 10 forms an independent experimental environment, which can be used for accurate small-scale experiments. When the control system 40 controls the gate 13 to be opened, the reservoir 10 is connected to the external environment, and the external environment is used to achieve a farther simulation distance and conduct a large-scale experiment. It is beneficial to avoid the experimental deviation caused by the size limitation of the reservoir 10, improve the authenticity of the simulation, and thus improve the accuracy of the experimental results. In this way, the switch control of the gate 13 can meet different sea condition simulation requirements, which is beneficial to improve the accuracy of marine engineering simulation.

[0049] In addition, when the gate 13 is closed, independent processing, inspection and maintenance conditions can be provided for each device in the reservoir 10.

[0050] During the implementation, the external environment 200 is the ocean, and the water reservoir 10 is set close to the ocean. When the gate 13 is opened, the first accommodating chamber 100 is connected to the external ocean. In this way, the real ocean conditions are simulated, and the external ocean environment is used to achieve natural wave absorption, avoiding experimental deviations caused by the limitations of the water reservoir 10, thereby improving the accuracy of marine engineering simulation, and further improving the reliability and applicability of the experimental results.

[0051] In some embodiments, the simulation system has multiple experimental modes, and each experimental mode corresponds to setting the switch state of the gate 13. The control system 40 is used to control the gate 13 to open or close according to the current experimental mode to perform the test in the experimental mode. For example, when the current experimental mode is a large wave experiment, the gate 13 is controlled to be opened. When the current experimental mode is a small scale experiment, the gate 13 is controlled to be closed.

[0052] Exemplarily, in some embodiments, the side wall 12 of the water reservoir 10 includes a first side wall, a second side wall and a third side wall respectively connected to both sides of the first side wall, and a fourth side wall with a gate 13. The first side wall, the second side wall, the third side wall, the fourth side wall, the gate 13 and the bottom wall 11 are enclosed together to form a first accommodating cavity 100. The second side wall is parallel to the third side wall and has the same length, the first side wall is parallel to the fourth side wall and has the same length, and the first side wall is perpendicular to the second side wall. In this way, a first accommodating cavity 100 in a rectangular shape is formed, which is conducive to more controllable adjustment and control of the environment in the first accommodating cavity 100.

[0053] Combination Figure 3 As shown, in some embodiments, the area of ​​the gate 13 is equivalent to the area of ​​the fourth side wall, and the second side wall 122 and the third side wall 123 are directly connected through the gate 13. At this time, it is equivalent to that the side wall 12 includes the first side wall 121 and the second side wall 122 and the third side wall 123 respectively connected to the two sides of the first side wall 121. The second side wall 122 and the third side wall 123 are parallel and of equal length, the first side wall 121 is parallel to the gate 13, and the first side wall 121 is perpendicular to the second side wall 122. In this way, when the gate 13 is opened, unobstructed communication can be achieved between the first accommodating chamber 100 and the external environment 200. In the process of large-scale experiments in which the first accommodating chamber 100 and the external environment 200 are connected, it is helpful to avoid the situation where the water flow is greatly affected by the obstruction of the side wall 12, and accurate and controllable sea state simulation cannot be achieved.

[0054] In some embodiments, the length of the first accommodating chamber 100 is greater than or equal to 100 meters, and the depth is greater than or equal to 15 meters. Further, in some embodiments, the length of the first accommodating chamber 100 is greater than or equal to 200 meters. In this way, compared with the existing simulation system, a larger simulation environment is provided, thereby more realistically reflecting the deep-sea environment, thereby improving the accuracy of the experimental results. And, in some embodiments, the width of the first accommodating chamber 100 is greater than or equal to 30 meters. To provide sufficient width for simulating various sea conditions.

[0055] Take the case where the first side wall 121, the second side wall 122, the gate 13, the third side wall 123 and the bottom wall 11 in the water reservoir 10 enclose a rectangular first accommodating cavity 100 as an example. The lengths of the second side wall 122 and the third side wall 123 are greater than the length of the first side wall 121. The lengths of the second side wall 122 and the third side wall 123 are used as the length of the first accommodating cavity 100, the length of the first side wall 121 is used as the width of the first accommodating cavity 100, and the lowest height among the first side wall 121, the second side wall 122 and the third side wall 123 is used as the depth of the first accommodating cavity 100 for size restriction.

[0056] It should be noted that, at least in some embodiments, the water reservoir 10 includes a water injection system. The water injection system can be used to inject water into the first accommodating chamber 100 in the water reservoir 10. Specifically, natural seawater can be injected into the first accommodating chamber 100 in the water reservoir 10, which is conducive to further ensuring the authenticity of density and related physical properties, thereby improving simulation accuracy.

[0057] Continue to combine Figure 3 As shown, in some embodiments, at least a portion of the top of the side wall 12 is provided with a through groove 1201, and the water in the first accommodating chamber 100 that reaches the side wall 12 and is higher than the through groove 1201 overflows through the through groove 1201. In this way, it is helpful to reduce the situation where the water contained in the first accommodating chamber 100 hits the side wall 12 at a greater height and splashes out, reduce the impact of the experimental process on the surrounding environment, and reduce the risk of affecting the equipment set near the side wall 12.

[0058] In some embodiments, the water reservoir 10 is constructed of corrosion-resistant materials, which is helpful to ensure that the water reservoir 10 can be used for experiments for a long time.

[0059] In some embodiments, at least part of the side wall 12 of the water reservoir 10 is provided with a transparent observation window. One or more observation windows are adaptively provided. In some embodiments, the observation window is made of high-strength, pressure-resistant material to avoid damage to the observation window due to excessive water pressure, thereby ensuring the feasibility of observing water phenomena during the experiment. Taking the case where the first side wall 121, the second side wall 122, the gate 13, the third side wall 123 and the bottom wall 11 in the water reservoir 10 enclose the first accommodating cavity 100 of a rectangular body as an example, observation windows can be provided on the second side wall 122 and the third side wall 123 to observe the current conditions in the first accommodating cavity 100.

[0060] In some embodiments, the simulation system further includes a display device 70, which is electrically connected to the control system 40 and is used to display parameter information of the water reservoir 10. In this way, real-time display of experimental data can be achieved, which facilitates the experimenter to connect to the experimental process in a timely manner.

[0061] Here, the environment simulation system 20 is further described.

[0062] Combination Figure 2 , Figure 3 As shown, the environment simulation system 20 includes one or more of a wave-making device 21 , a fan device 22 and a flow-making device 23 .

[0063] The wave-making device 21 is disposed in the reservoir 10, and is used to generate and control waves in the first accommodating chamber 100. In this way, accurate simulation of wave conditions can be achieved, and it is convenient to test the parameter changes related to the waves.

[0064] Specifically, in some embodiments, the wave-making device 21 uses a hydraulic drive system 211 or a swing plate drive system to drive the wave-making plate 212, and simulates different wave conditions by adjusting the wave amplitude, wavelength and wave speed. The use of a hydraulic drive or a swing plate drive system can generate large waves with a height of 5 to 6 meters, thereby improving the authenticity of the experimental simulation and achieving precise control of the generated waves.

[0065] More specifically, the wave-making device 21 uses a hydraulic drive system 211 or a swing plate drive system to drive the wave-making plate 212 in the wave-making process, and has the ability to generate multiple waveforms including sine waves, square waves, triangle waves, etc. In some embodiments, the adjustable amplitude range of the wave-making device 21 is 0.1 meters to 6 meters to meet different experimental requirements. By adjusting the amplitude and frequency, the accurate generation of waves is ensured. The operating system of the wave-making device 21 is connected to the control system 40, which monitors the wave parameters in real time and generates the target waveform according to the preset program. Therefore, during the experiment, the high consistency of the trough and peak waveforms of the waves is achieved through precise control.

[0066] In some embodiments, the reservoir 10 has a first end and a second end opposite to each other, the gate 13 is disposed at the first end of the reservoir 10, and the wave-making device 21 is disposed at the second end of the reservoir 10. In this way, the wave-making device 21 is disposed opposite to the gate 13, which can ensure that the flow of water will push the waves generated by the wave-making device 21 to propagate toward the other end of the reservoir 10 where the gate 13 is disposed, forming relatively stable waves. At the same time, it can prevent the wave-making device 21 from being too close to the gate 13, resulting in the water flow disturbance at the gate 13 directly affecting the generation of waves when the gate 13 is opened, which is conducive to maintaining the stability of the waves, improving the accuracy of the sea condition simulation, and improving the accuracy of the experimental results.

[0067] The aforementioned fan device 22 is used to generate a controllable airflow environment in the first accommodating chamber 100 to simulate the airflow conditions in an actual marine environment. The fan device 22 is electrically connected to the control system 40, and at least part of the air outlet height, air outlet direction, and air outlet speed of the fan device 22 can be controlled and changed. In some embodiments, the fan device 22 includes a plurality of controllable fans to improve the flexibility of airflow environment control and further improve the accuracy of airflow environment simulation.

[0068] In some embodiments, the simulation system also includes a fan movable track 220, which is arranged along the side wall 12 of the water reservoir 10. The fan device 22 is slidably connected to the fan movable track 220. In this way, the fan device 22 can slide along the fan track to adjust the air outlet position, which can achieve more flexible control compared to the fixed position setting method, thereby improving the accuracy of the airflow environment generated by the fan device 22. The setting position of the fan movable track 220 is further explained. In some embodiments, the fan movable track 220 is arranged on the outside of the water reservoir 10 along the side wall 12 of the water reservoir 10, and the air outlet of the fan device 22 is higher than the height of the side wall 12, so that the air outlet of the fan device 22 blows into the first accommodating chamber 100.

[0069] The flow-generating device 23 is disposed in the water reservoir 10, and is used to generate a controllable water flow environment in the first accommodating chamber 100. In this way, the simulation of the water flow environment in the water reservoir 10 can be achieved. The flow-generating device 23 is used to change at least one of the water flow direction and the water flow velocity in the first accommodating chamber 100. Specifically, in some embodiments, the water reservoir 10 has a first side and a second side opposite to each other, and the first side and the second side are adjacent to the first end and the second end respectively, and the flow-generating device 23 is disposed on the first side and the second side of the water reservoir 10. In this way, the water flow control in the direction from the first end to the second end can be achieved.

[0070] Taking the case where the first side wall 121, the second side wall 122, the gate 13, the third side wall 123 and the bottom wall 11 in the water reservoir 10 enclose a first accommodating chamber 100 of a rectangular body as an example, the end where the first side wall 121 is located is the first end, and the end where the gate 13 is located is the second end. The second side wall 122 is the aforementioned first side, and the third side wall 123 is the aforementioned second side. The wave-making device 21 is arranged near the first side wall 121 relative to the gate 13. More specifically, in some embodiments, the wave-making device 21 is arranged on the inner wall of the first side wall 121. The flow-making device 23 is respectively arranged on the second side wall 122 and the second side wall 122.

[0071] It should be further explained that, in some embodiments, the environmental simulation system 20 includes the aforementioned wave-making device 21, the fan device 22 and the flow-making device 23. In this way, the fully coupled simulation of multiple physical phenomena such as wind, waves and flow can be realized, reflecting the mutual influence between multiple physical effects including fluid dynamics, aerodynamics and structural dynamics in the deep-sea environment. The simultaneous real simulation of multiple factors is realized, which is conducive to improving the accuracy and reliability of the experimental results.

[0072] Here we continue to combine Figure 4 and Figure 5 The measurement system 30 is further described.

[0073] The measuring system 30 includes a first sensor system for monitoring first environmental parameter information in the first accommodating chamber 100 and is electrically connected to the control system 40. The first environmental parameter information includes at least one of wave height, water flow velocity, and wind speed. In this way, real-time monitoring of environmental parameters in the first accommodating chamber 100 can be achieved.

[0074] In some embodiments, the simulation system further includes a sensor moving track 3110 connected to the side wall 12 of the water reservoir 10. The first sensor system includes a first sensor device 311 slidably connected to the sensor moving track 3110, and the first sensor device 311 is electrically connected to the control system 40, and the first sensor device 311 can be controlled to move to monitor the first environmental parameter information at different positions in the first accommodating cavity 100. In this way, the monitoring position of the first sensor device 311 can be adjusted according to actual needs, which is conducive to improving the accuracy of the first environmental parameter information.

[0075] In some embodiments, the moving speed of the first sensor device 311 reaches 5 meters per second to achieve real-time data collection in a high-dynamic experimental environment. In some embodiments, the moving accuracy of the first sensor device 311 reaches sub-millimeter level to ensure the accuracy of the control of the first sensor device 311 during the experiment.

[0076] Specifically, in some embodiments, the sensor mobile track 3110 includes a first mobile track 3101, a second mobile track 3102 and a third mobile track 3103; and the first mobile track 3101, the second mobile track 3102 and the third mobile track 3103 are perpendicular to each other. In this way, the mobile control of the first sensor device 311 in three dimensions is realized, and compared with the mobile control in a single direction or a single plane, the movable range of the first sensor device 311 is increased, that is, the first sensor device 311 can realize environmental parameter monitoring of more different positions. At the same time, setting the first mobile track 3101, the second mobile track 3102 and the third mobile track 3103 to be perpendicular to each other facilitates the position control of the first mobile device during the implementation process, which is conducive to improving the control accuracy. It should be noted here that the first mobile track 3101, the second mobile track 3102 and the third mobile track 3103 in the sensor mobile track 3110 are only distinguished by direction, and the number of sensor mobile tracks 3110 is not limited to only three.

[0077] In some embodiments, the top surface of the side wall 12 is provided with a groove 1202 that matches the sensor moving track 3110, and at least part of the sensor moving track 3110 is disposed in the groove 1202. In this way, the sensor moving track 3110 can be stably disposed, which is beneficial to improving the stability of the movement control of the first sensor device 311.

[0078] Here, an example of the arrangement of the sensing moving track 3110 is provided. The first moving track 3101 and the second moving track 3102 are both arranged in a plane parallel to the bottom wall 11 of the water reservoir 10, and the arrangement plane is located above the water reservoir 10. The third moving track 3103 is arranged perpendicular to the arrangement plane, and at least partially extends toward the bottom wall 11. More specifically, the side wall 12 of the water reservoir 10 includes a first side wall 121, a second side wall 122, and a third side wall 123. The first side wall 121, the second side wall 122, the gate 13, and the third side wall 123 are connected in sequence, and are all connected to the bottom wall 11 to enclose a rectangular space. In the case of the first accommodating cavity 100, the top surfaces of the second side wall 122 and the third side wall 123 are both provided with grooves 1202, and the first moving track 3101 is arranged in the grooves 1202 on the top surfaces of the second side wall 122 and the third side wall 123, and the two parts of the first moving track 3101 are parallel to each other. The second movable track 3102 is arranged parallel to the first side wall 121, connecting the two movable tracks arranged on the second side wall 122 and the third side wall 123. The third movable track 3103 is arranged perpendicular to the plane where the bottom wall 11 is located, and at least partially extends toward the bottom wall 11.

[0079] In some embodiments, the first sensing system includes a second sensing device 312, and the distance between the second sensing device 312 and the gate 13 is less than the first set distance, and is used to monitor the first environmental parameter information at the gate 13. That is, the second sensing device 312 is arranged close to the gate 13. More specifically, when the gate 13 is arranged at the first end of the reservoir 10 and the wave-making device 21 is arranged at the second end of the reservoir 10, the second sensing device 312 is arranged close to the gate 13 relative to the wave-making device 21. In this way, accurate monitoring of the environmental parameter information at the gate 13 can be achieved, especially when the gate 13 is open, the influence of the external environment 200 on the parameters in the first accommodating chamber 100 can be reflected.

[0080] In some embodiments, the second sensing device 312 includes a wave height sensor 3121 for monitoring wave height and is electrically connected to the control system 40. Further, the wave height sensor 3121 can perform high-precision measurements within a range of 0 to 5 meters to ensure real-time monitoring of wave dynamics in wave experiments.

[0081] In some embodiments, the second sensing device 312 includes a flow rate sensor 3122, which is used to monitor the flow rate of the water flow and is electrically connected to the control system 40. Further, the flow rate sensor 3122 monitors the flow rate at multiple points at different positions to achieve comprehensive collection of the flow rate. The data accuracy of the flow rate sensor 3122 reaches the sub-millimeter level to ensure the accuracy of the flow rate monitoring.

[0082] In some embodiments, the second sensing device 312 includes a wind speed sensor 3123 for monitoring wind speed and is electrically connected to the control system 40. At least in some embodiments, the position of the wind speed sensor 3123 is movable to flexibly adjust the position according to different experimental requirements to improve the accuracy of the wind speed data finally monitored.

[0083] In some embodiments, the first sensing system further includes a third sensing device 313, the distance between the third sensing device 313 and the environment simulation system 20 is less than the second set distance, and is used to monitor the impact of the environment simulation system 20 on the first environment parameter information in the first accommodating chamber 100. In this way, setting the third sensing device 313 close to the environment simulation system 20 is conducive to reducing the impact of the environment in the first accommodating chamber 100 and accurately monitoring the sea state simulation effect. The third sensing device 313 can realize real-time feedback on the sea state simulation effect, and the controller can further adjust the environment simulation system 20 according to the first environment parameter information feedback monitored by the third sensor to improve the accuracy of the sea state simulation.

[0084] In some embodiments, the third sensing device 313 includes a wave feedback sensor 3131 for monitoring the wave conditions in the reservoir 10. The operating state of the wave-making device 21 can be further adjusted according to the wave conditions, thereby improving the accuracy of the wave simulation conditions.

[0085] In some embodiments, the third sensing device 313 includes a wind speed feedback sensor 3132 for monitoring the wind speed in the reservoir 10. The operating state of the fan device 22 can be further adjusted according to the current wind speed, thereby improving the accuracy of the wind speed simulation condition.

[0086] In some embodiments, the third sensing device 313 includes a flow rate feedback sensor 3133 for monitoring the flow rate of water in the reservoir 10. The operating state of the flow generating device 23 can be further adjusted according to the current flow rate, thereby improving the accuracy of the water flow simulation conditions.

[0087] In some embodiments, the measurement system 30 includes an image system 32. The image system 32 is used to obtain image information of the reservoir 10 to measure the motion response of the floating structure in the reservoir 10 during the sea state simulation, and the image system 32 is electrically connected to the control system 40. In this way, the working characteristics of the floating structure during different sea state simulations can be monitored. Specifically, the image system 32 can be a high-definition camera.

[0088] In some embodiments, the image system 32 includes a plurality of image acquisition devices, and the image acquisition devices are arranged along the side wall 12 of the water reservoir 10 in different directions around the side wall 12. This is conducive to ensuring the integrity of the angle of the image finally obtained, thereby improving the accuracy of the test results. Taking the case where the first side wall 121, the second side wall 122, the gate 13, the third side wall 123 and the bottom wall 11 in the water reservoir 10 enclose the first accommodating cavity 100 of a rectangular body, and the lengths of the second side wall 122 and the third side wall 123 are greater than the length of the first side wall 121 as an example, a plurality of image acquisition devices are respectively arranged on both sides of the water reservoir 10, and are arranged along the outer side of the second side wall 122 and the outer side of the third side wall 123.

[0089] In addition, in some embodiments, a propulsion system is provided on the first sensing device 311, and the propulsion system is electrically connected to the control system 40. The propulsion system is used to drive the water flow in the first accommodating chamber 100, and the control system 40 is used to control at least one of the driving speed and driving direction of the water flow by the propulsion system. In this way, a stable flow field can be achieved in the first accommodating chamber 100 through the propulsion system, as one of the flow generation methods, so that the first sensing device 311 also has the function of controlling the water flow environment. More specifically, in some embodiments, the propulsion system includes a plurality of propulsion devices installed on the first sensing device 311. In this way, the control accuracy of the water flow driving process can be improved. Specifically, the propulsion system includes, for example, a propeller or a water pump.

[0090] In some embodiments, the measurement system 30 is connected to the control system 40 using wireless data transmission technology to transmit the collected data to the control system 40 in real time. This is conducive to ensuring rapid feedback of real-time data, data analysis and result output.

[0091] In some embodiments, in combination Figure 6 As shown, the simulation system also includes a first height adjustment device 50, which is arranged below the bottom wall 11 of the water reservoir 10 and can be controlled to extend and retract to change the vertical height of the water reservoir 10. The first height adjustment device 50 is electrically connected to the control system 40, and the control system 40 is used to control the extension and retraction of the first height adjustment device 50 according to the height adjustment requirements of the water reservoir 10. When the first accommodating chamber 100 of the water reservoir 10 is connected to the external marine environment, the simulation of different depths in the first accommodating chamber 100 can be achieved by adjusting the height of the water reservoir 10. In this way, environments of different water depths can be simulated in the water reservoir 10, providing more realistic and richer experimental conditions for the test, which is conducive to improving the accuracy of the test results. In some embodiments, the height adjustment range of the first height adjustment device 50 is 0 to 10 meters to meet the adjustment requirements of different depths.

[0092] Specifically, the first height adjustment device 50 includes a support portion 51, a lifting portion 52 and a contact portion 53. The contact portion 53 contacts the side of the bottom wall 11 of the water reservoir 10 away from the first accommodating chamber 100, and the lifting portion 52 connects the contact portion 53 and the support portion 51. The lifting portion 52 is used for controlled extension and retraction to change the distance between the support portion 51 and the contact portion 53, so that the contact portion 53 drives the bottom wall 11 to rise and fall. The lifting portion 52 is electrically connected to the control system 40, and the control system 40 is used to control the extension and retraction of the lifting portion 52 according to the height adjustment requirements of the water reservoir 10. In this way, the specific adjustment of the height of the water reservoir 10 is achieved.

[0093] More specifically, the contact portion 53 is a plane so as to distribute and balance the weight of the water storage tank 10. The lifting portion 52 is a hydraulic system, which can achieve rapid lifting. The support portion 51 includes a plurality of support points to ensure the stability of the lifting process of the contact portion 53 and prevent the contact portion 53 from tilting or deforming. More specifically, at least part of the first height adjustment device 50 is made of high-strength alloy material, which can withstand the weight of large marine equipment and structures, and is conducive to ensuring the stability of the lifting process. At the same time, it has good corrosion resistance, which is conducive to ensuring long-term stable operation.

[0094] The aforementioned measuring system 30 also includes a fourth sensor device 314 for monitoring the height and stability of the first height adjustment device 50. The fourth sensor device 314 is electrically connected to the control system 40. In this way, it is convenient to feed back the adjustment data of the current height sensor device in real time so that the experimenter can perform necessary maintenance and adjustment.

[0095] For example, when testing an offshore engineering structure represented by a tension leg floating platform, the test well 60 can evaluate the load-bearing capacity and structural strength of the tension leg through a static load test. A specific load is applied to the tension leg, and its displacement and deformation are recorded through the test well 60 to analyze its support performance in a deep sea environment. The response of the tension leg is observed by applying periodic or random loads. The load is used to simulate dynamic marine environmental factors such as waves, currents, and wind. The tension changes and dynamic responses of the tension leg are monitored in real time through the third sensor device 313 set in the test well 60 to evaluate its fatigue resistance and durability.

[0096] On the basis of the support part 51, the lifting part 52 and the contact part 53, in some embodiments, the simulation system further includes a rotating shaft 54. The rotating shaft 54 ​​is arranged on the contact part 53, and the control system 40 is used to control the lifting parts 52 on both sides of the rotating shaft 54 ​​to extend to different lengths according to the slope adjustment requirements of the water reservoir 10, so that the contact part 53 drives the bottom wall 11 to rotate along the rotating shaft 54. In this way, it is possible to accurately simulate the sea environment with terrain conditions of different slopes, which is conducive to improving the accuracy of experimental tests. In at least some embodiments, the slope adjustment angle range is 0° to 30°, and the slope adjustment angle is specifically set according to actual needs.

[0097] The fourth sensor device 314 is also used to monitor the tilt angle of the contact portion 53, and feeds back to the control system 40 through the electrical connection with the control system 40, so as to facilitate the experimenter to determine the current slope condition and control.

[0098] Specific combination Figure 3 , Figure 5 As shown, the simulation system also includes a test deep well 60, which is opened on the bottom wall 11 of the reservoir 10 and extends in a direction away from the first accommodating chamber 100 to form a second accommodating chamber 600. In this way, a true simulation of a deeper environment can be achieved on the basis of the reservoir 10, and combined with the reservoir 10, the complex conditions in the deep-sea environment can be simulated to improve the accuracy of the simulation and further testing processes. For example, the test deep well 60 can provide a series of key tests for the tension-leg floating platform to evaluate its stability, reliability and wind and wave resistance in the deep-sea environment.

[0099] In some embodiments, the depth of the test well 60 is greater than or equal to 50 meters, so as to achieve a true simulation of extreme conditions in a deep sea environment.

[0100] It can be understood that the second accommodating chamber 600 of the test deep well 60 is formed by the bottom wall 11 and the side wall 12. In some embodiments, a second height adjustment device is provided under the bottom wall 11 of the test deep well 60 to adjust the height of the test deep well 60. The second height adjustment device can be provided in a similar structural manner to the aforementioned first height adjustment device 50, which will not be described in detail here.

[0101] When the test deep well 60 is provided, the measurement system 30 is also used to monitor parameter information in the test deep well 60. Figure 7 As shown, in some embodiments, the test system further includes a second sensor system 33, which is disposed in the second accommodating chamber 600 and is used to test the second environmental parameter information in the second accommodating chamber 600. The second environmental parameter information includes at least one of temperature and pressure. For example, the second sensor system 33 includes a temperature sensor 331 and a pressure sensor 332 disposed in the second accommodating chamber 600, which can monitor the temperature and pressure in the test deep well 60 in real time, thereby realizing real-time monitoring of the parameters in the test deep well 60.

[0102] In some embodiments, the first accommodating chamber 100 is a rectangular body, and the projection of the test deep well 60 on the bottom wall 11 passes through the central axis of the bottom wall 11. More specifically, the second accommodating chamber 600 is a cylinder, and the projection of the test deep well 60 on the bottom wall 11 is a circle, and the center of the projection is on the central axis of the bottom wall 11. In this way, it is helpful to improve the balance of the influence of the environment in the first accommodating chamber 100 on the environment in the first accommodating chamber 100 on both sides of the test deep well 60, and avoid the environment in the first accommodating chamber 100 from having too great an influence on the second accommodating chamber 600, thereby helping to improve the accuracy of parameter testing in the second accommodating chamber 600.

[0103] In some embodiments, in combination Figure 7 As shown, the simulation system also includes a circulation system 61. The circulation system 61 includes a circulation pipe 611 and a circulation pump 612. The circulation pipe 611 connects the first accommodating chamber 100 and the second accommodating chamber 600, and the circulation pump 612 is used to provide power for the water flow circulation between the first accommodating chamber 100 and the second accommodating chamber 600. In this way, the liquid circulation between the second accommodating chamber 600 of the test deep well 60 and the overall water reservoir 10 is realized, the continuity and stability of the water flow during the test are guaranteed, which is conducive to simulating the dynamic water flow environment in the deep sea, thereby improving the test accuracy.

[0104] Combination Figure 8As shown, the control system 40 includes multiple interfaces for realizing communication connection between various devices and the control system 40. Specifically, it includes: an environmental simulation system control interface 41 for connecting to the environmental simulation system 20, a measurement system control interface 42 for connecting to the measurement system 30, a test deep well control interface 43 for connecting to the test deep well 60, and a first height adjustment device control interface 44 for connecting to the first height adjustment device 50.

[0105] According to the different connection requirements determined by the current simulation system settings, the number and purpose of the interfaces can be adaptively adjusted. For example, in some embodiments, a wave-making device 21 control interface for controlling the wave-making device 21, a fan device 22 control interface for controlling the fan device 22, and a flow-making device 23 control interface for controlling the flow-making device 23 can be separately set. In this way, the use of modular design is conducive to realizing flexible combination between various modules, and each device can be configured according to the current actual experimental needs. When conducting different types of experiments, the equipment can be quickly replaced as needed to meet a variety of experimental needs, which greatly improves the adaptability and flexibility of the simulation system and can cope with different experimental challenges.

[0106] Here, combined Fig. 9 As shown, an example is given to illustrate the operation process of the simulation system provided by this application during the implementation process.

[0107] Step S11, setting various parameters in the control system 40 according to experimental requirements.

[0108] Before the experiment begins, the experimenter needs to set various parameters in the control system 40 according to the experimental requirements and prepare for the experiment. The various parameters here include, for example, wave type, wind speed, flow speed, etc.

[0109] Step S12, starting the water filling system of the water reservoir 10, and filling the water reservoir 10 with water to a set water depth.

[0110] The experimenter starts the water filling system of the water reservoir 10 to ensure that the water reservoir 10 is filled to the set water depth and the water reservoir is filled. During the water filling process, the water temperature, pressure and other parameters are monitored to ensure the stability of the experimental environment.

[0111] Step S13, configuring modular components according to experimental requirements.

[0112] According to the experimental requirements, the experimenters configure the modular components, such as adjusting the height of the height adjustment device, the depth of the test deep well 60, the positions of the fan device 22 and the flow rate feedback sensor 3133, etc.

[0113] Step S14, starting the simulation system.

[0114] The wave-making device 21 is started, and the wave parameters are monitored in real time to ensure that the generated waves meet the preset conditions.

[0115] Step S15 , monitoring the water reservoir 10 and testing the parameter information in the deep well 60 .

[0116] During the experiment, the measurement system 30 is used to monitor the parameter information such as wave, wind speed and flow speed in real time, and the control system 40 is used to record and analyze the data.

[0117] Step S16, shut down the simulation system.

[0118] After the experiment is over, the experimenter can stop the operation of each device in the simulation system and sort out and analyze the data. The control system 40 will automatically generate an experimental report.

[0119] It should be further explained that by adopting the simulation system provided by the present application, the test cycle of the prototype can be greatly shortened, and the time for the four-season sea condition test is reduced from the traditional 365 days to only 7 days, and the time efficiency is improved by 98%. This efficient testing method not only accelerates the iteration and upgrading of technology, but also can provide a more stable and controllable testing environment, significantly reducing the risk in the testing process. In addition, during the test process, if any fault or abnormality occurs in the prototype, the simulation system provided by the present application can immediately stop the environmental simulation process such as wave making to ensure that the equipment will not be damaged or water damaged, which greatly improves the safety and controllability of the testing process. Therefore, the simulation system provided by the present application can not only complete the test task faster and more effectively, but also avoid unforeseen problems that may occur in offshore testing, significantly reduce risks, and improve the economy and practicality of the test. The simulation system provided by the present application makes the technical verification and optimization of the prototype more flexible and efficient, has important practical value, and provides a safer and more reliable solution for future deep-sea engineering and marine equipment testing.

Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include at least one of the features.
