Description

Technical Field

[0001] This utility model relates to the technical field of deep-sea engineering experimental devices, specifically to a multifunctional deep-sea environment simulation system. Background Technology

[0002] Marine engineering structures are subjected to the combined effects of various environmental loads, such as wind, waves, and currents, in the complex marine environment. These loads are not only random and dynamic but may also generate complex coupling effects, posing extremely high demands on the design, construction, and maintenance of these structures. Conducting relevant physical experiments is crucial for in-depth research and evaluation of the impact of the marine environment on structures. Through experiments, the real marine environment can be simulated, the safety and reliability of structures can be verified, and a scientific basis can be provided for engineering design. Among these, wind-wave coupling experimental devices, as experimental equipment capable of simulating marine wind and wave environments, are of great significance for promoting the development of the marine engineering field, improving the design level of structures, and ensuring the safety of marine engineering projects.

[0003] Currently, domestic laboratories typically use devices such as fans and wave tanks to simulate wind and wave loads separately, applying both loads simultaneously to structures. However, this method has significant limitations: wind and wave loads are usually applied independently, lacking a clear coupling relationship and failing to accurately reflect the interaction between wind and waves at sea. For example, in actual marine environments, wind alters wave morphology and energy distribution, while wave motion, in turn, affects wind field distribution. Existing experimental setups cannot accurately simulate this complex wind-wave coupling effect, leading to significant deviations between experimental results and actual marine conditions, thus limiting the accuracy and reliability of the experiments. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional deep-sea environment simulation system that simultaneously conducts experimental simulations of the combined effects of multiple factors, significantly improving design accuracy; and realizing the wind and wave coupling effect on structures to simulate the real marine wind and wave environment.

[0005] To achieve the above objectives, the technical solution of this application is: a multifunctional deep-sea environment simulation system, comprising:

[0006] The wave and current experimental water tank is a water-bearing cavity with an open top. The inside of the water tank is arranged in sequence according to the wind direction: deep water experimental zone, transition experimental zone, and shallow water experimental zone.

[0007] A fan array is installed above the wave-current experimental water tank to provide the wind field required for the experiment above the water body; two or more fan arrays are installed and fixed above the wave-current experimental water tank, and the flow guide array is located on both sides of the fan array.

[0008] The airflow guide arrays are respectively arranged at the inlet and outlet of the wind farm to guide and control the air generated by the wind turbine array;

[0009] The flow-generating array is connected to the receiving cavity of the wave-current experimental water tank and is used to generate flow, and to complete the circulation of water in the wave-current experimental water tank through the return flow path; the flow-generating array is located below the wind field inlet end and is attached to the outer wall of the wave-current experimental water tank.

[0010] A wave-generating array is set up in a wave-current experimental tank to generate waves of different periods and heights in the water.

[0011] Wave damping plates, located inside the wave flow experimental tank, are used to dissipate the energy of the generated waves.

[0012] As a preferred option, a shaking table is also included, installed in the shallow water test area, to simulate seismic loads of different intensities required for the experiment.

[0013] As a preferred option, it also includes a rising floating bottom located in the wave and current experimental tank to simulate different experimental water depth changes and seabed elevation changes from deep sea to shallow sea.

[0014] As a preferred embodiment, the wave-generating array is an L-shaped wave generator, located in the deep-water test area and the shallow-water test area respectively, and attached to the inner wall of the wave-current test tank.

[0015] As a preferred embodiment, the current-generating array is arranged below the wave-generating array in the deep-water test area.

[0016] As a preferred embodiment, the floating bottom is supported by a floating bottom support rod, which is fixed in the foundation.

[0017] As a preferred embodiment, the vibration table is installed at the bottom of the shallow water test area and fixed in the foundation.

[0018] As a preferred embodiment, the lifting and floating bottom is located in the deep-water test area and the transition test area.

[0019] As a preferred embodiment, the height of the floating bottom is manually controlled, and the deep-water experimental area and the shallow-water experimental area are connected by a sloped floating bottom section in the transition experimental area, thus simulating the elevation changes of the real seabed.

[0020] It should be noted that the wind generated by the wind turbine array is guided and controlled by the guide array and enters the experimental area above the wave flow experimental tank through the wind field inlet; at the same time, the wave generating array synchronously generates wave fields of regular and irregular waves in multiple directions; the wind flowing through the experimental area returns to the location of the wind turbine array after being guided by the wind field outlet and the guide array, realizing the circulation of the wind field in the experimental area.

[0021] By adopting the above technical solution, this utility model can achieve the following technical effects:

[0022] 1.

The current-generating array in the deep-water experimental area can work together with the wind tunnel, wave generators, etc. to achieve wind and wave coupling effect on the structure and simulate the real marine wind and wave environment.

[0023] 2. By combining the atmospheric boundary layer wind tunnel with the deep water tank, the synchronous reproduction of ocean waves and sea breezes can be achieved, breaking through the current focus on single-factor effects and simultaneously carrying out experimental simulations of multi-factor combined effects, thus significantly improving design accuracy.

[0024] 3. The floating pool bottom at the bottom of the wave-current experimental tank can adjust the water depth to meet the requirements of different water depths in the experiment. At the same time, it can simulate the entire process of waves being generated in the open sea and gradually propagating to the shallow sea under the coupling effect of wind and waves.

L-shaped wave generators 11 are arranged on both sides of the tank.

[0030] The wind turbine array 8 generates a high-intensity wind field and guides the airflow through the flow guide array 10, which can employ deflectors to reduce the impact of turbulence. The flow guide array introduces and guides the high-quality wind field into the wind field inlet, providing high-precision simulation of marine wind loads for the experiment. The flow guide array is located at both the air inlet and outlet. The L-shaped wave generator can produce multi-directional irregular waves to simulate marine wave loads; the flow generating array 9 is located below the L-shaped wave generator 11, providing the necessary stable flow field for the experiment.

[0031] The floating platform 2 can be raised and lowered to a specified depth position according to the requirements of the experimental water depth.

The vibration table 4 realizes high-precision simulation of different levels of seismic loads according to the test requirements. The transition test area 6 works together with the floating platform 2 to connect and penetrate the deep water test area 5 and the shallow water test area 7, simulating the seabed topography changes from deep sea to shallow sea.

[0032] The wind field provided by the wind turbine array 8 of this utility model enters and exits the water tank experimental area through the guide array 10.
