[0002] Marine engineering structures (such as bridge piers and offshore wind turbine foundations) are subjected to cyclic loads from waves and tides, as well as corrosive environments characterized by high salinity and humidity, leading to increasingly prominent durability issues. To investigate the performance degradation patterns of materials and structures in marine environments, simulation experiments are necessary in the laboratory.

[0003] In related technologies, the experimental equipment has the following shortcomings: 1. Single function: Most devices can only simulate a single factor (such as immersion corrosion or simple wave impact), lacking the comprehensive simulation capability for the coupled effects of multiple factors such as load, wet-dry cycle, and water quality parameters; 2. Outdated monitoring methods: The monitoring of the corrosion state of components mostly adopts periodic broken sampling or external specimen method, which cannot conduct in-situ, real-time, and continuous monitoring of large components in the pool, resulting in discontinuous and unrepresentative data; 3. High energy consumption: High-power equipment such as wave generators, circulating water pumps, and loading devices, as well as continuously operating monitoring systems, have high energy consumption, which does not conform to the green and low-carbon research trend; 4. Low degree of automation: The control and monitoring of environmental parameters such as water level, water temperature, and salinity mostly rely on manual operation, which is inefficient and difficult to guarantee accuracy. Utility Model Content

[0004] The purpose of this application is to provide a marine environmental corrosion testing equipment that is self-generating and adaptable to multi-scenario and multi-parameter intelligent monitoring, aiming to solve the technical problems of testing equipment that can only simulate a single factor, outdated monitoring methods, high energy consumption, and low degree of automation.

[0005] To achieve the above objectives, the technical solution adopted in this application embodiment is: a self-generating marine environmental corrosion testing equipment adapted to multi-scenario and multi-parameter intelligent monitoring, including a water tank body, an environmental simulation system, a component holding system, a monitoring system, a control system, and a power supply system.

[0006] The water tank body includes a main water tank and a storage tank, which are separated by a partition wall. The environmental simulation system includes a water level control module, a wave-generating module, and a water quality maintenance module. The water level control module is used to adjust the water level of the main water tank. The wave-generating module is located in the main water tank and is used to generate simulated ocean waves. The water quality maintenance module is used to maintain the water quality in the main water tank. The component holding system is used to apply a continuous load to the test component located in the main water tank. The monitoring system is used to collect environmental parameters in the main water tank and state parameters of the test component in real time. The environmental simulation system, the component holding system, and the monitoring system are all communicatively connected to the control system. The control system controls the operation of the environmental simulation system and the component holding system, and receives and processes data from the monitoring system. The power supply system includes an independent power generation module, a storage module, and a power supply module. The power generation module is a new energy power generation device, and its output is electrically connected to the storage module. The output of the storage module is electrically connected to the monitoring system and the control system. The power supply module is a mains power interface or a high-power power supply, and its output is electrically connected to the environmental simulation system and the component holding system.

[0007] The beneficial effects of the self-generating, multi-scenario, multi-parameter intelligent monitoring marine environmental corrosion testing equipment provided in this application embodiment are as follows: the wave-generating module can generate water flow motion simulating real ocean waves in the main pool; the component-bearing system can apply continuous loads to the test components, restoring the structural stress borne by the marine engineering test components during service; the water level control module, through the coordinated work of the opening and closing device and the water pump, realizes the periodic rise and fall of the water level in the main pool, accurately simulating the dry-wet cycle effect brought about by the ebb and flow of tides; the water quality maintenance module maintains the stability of parameters such as microorganisms in the liquid in the main pool, matching the water quality characteristics of different sea areas. It can integrate wave generation, bearing, dry-wet cycle, and water quality control functions into one. Under the synergistic effect of multiple functions, the equipment can reproduce the complex environment of different marine scenarios such as nearshore, deep sea, and intertidal zone, making the test data more consistent with the actual service conditions of the components, and providing a more reliable basis for the corrosion-resistant design of marine engineering materials and structures. The monitoring system collects environmental parameters and test component status parameters in the main water tank in real time. The control system receives and processes the data from the monitoring system. The monitoring and control systems work together to monitor and process data in real time, ensuring data continuity and providing a more reliable basis for the corrosion-resistant design of marine engineering materials and structures. The environmental simulation system and component holding system are high-energy-consuming modules, which can meet their high-power requirements by being powered by mains electricity or a high-power power supply. The monitoring and control systems, however, have lower energy consumption and can be powered by new energy power generation modules. This partitioned power supply mode of "high-energy-consuming modules powered by mains electricity + low-energy-consuming modules powered by new energy sources" reduces the power configuration of new energy power generation devices, lowering the initial cost of equipment; it also reduces mains electricity consumption, achieving energy conservation and emission reduction. Furthermore, powering the monitoring and control systems from the new energy power generation modules ensures that the parameters of the test components and the environment are always collected by the monitoring system and analyzed by the control system, ensuring no data loss and achieving full life-cycle data acquisition. The control system controls the operation of the environmental simulation system and the component holding system to automatically control environmental parameters and the load on the test components, reducing reliance on manual operation and increasing automation.

[0010] In some embodiments, the opening and closing device includes an actuator and a seal; the seal is in sealing engagement with the overflow orifice, and the actuator is configured to drive the seal to move relative to the overflow orifice to open or close the overflow orifice.

[0011] In some embodiments, the seal is configured to be inserted into the overflow orifice under the actuation of the actuator to close the overflow orifice, or to be withdrawn from the overflow orifice to open the overflow orifice.

[0012] In some embodiments, the seal includes a plug portion and a stop portion, the stop portion protruding radially outward from the plug portion; when the plug portion is inserted into the overflow hole, the stop portion abuts against the wall surface of the partition wall facing the main water tank and surrounding the overflow hole.

[0013] In some embodiments, there are multiple overflow holes, which are spaced apart in the height direction of the main water tank. There are multiple opening and closing devices, which are configured one-to-one with the overflow holes, and each opening and closing device can be controlled independently to achieve multi-level adjustment of the water level in the main water tank.

[0014] In some embodiments, the water quality maintenance module includes an ultraviolet disinfection lamp disposed on the upper part of the main water tank, the ultraviolet disinfection lamp being used to irradiate and disinfect the liquid in the main water tank.

[0015] In some embodiments, the component holding system is a hydraulic loading system that applies a continuous load to the test component via hydraulic drive.

[0026] Marine engineering structures (such as bridge piers and offshore wind turbine foundations) are subjected to cyclic loads from waves and tides, as well as corrosive environments characterized by high salinity and humidity, leading to increasingly prominent durability issues. To investigate the performance degradation patterns of materials and structures in marine environments, simulation experiments are necessary in the laboratory.

[0027] In related technologies, the experimental equipment has the following shortcomings: 1. Single function: Most devices can only simulate a single factor (such as immersion corrosion or simple wave impact), lacking the comprehensive simulation capability for the coupled effects of multiple factors such as load, wet-dry cycle, and water quality parameters; 2.

[0028] In view of the above problems, this application provides a marine environmental sustained corrosion testing equipment that can generate its own power and is adapted to multi-scenario and multi-parameter intelligent monitoring. It aims to solve the technical problems of the testing equipment being able to simulate only a single factor, the monitoring methods being outdated, the energy consumption being high, and the degree of automation being low.

[0029] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0030] Please refer to Figure 1 This application provides a self-generating marine environmental corrosion testing equipment that is adaptable to multi-scenario and multi-parameter intelligent monitoring, including a water tank body, an environmental simulation system, a component holding system, a monitoring system, a control system, and a power supply system.

[0031] The water tank body includes a main water tank 1 (generally, both the main water tank 1 and the storage tank 2 are used to hold sodium chloride solution simulating seawater, and the test component 10 is set in the main water tank 1) and a storage tank 2, which are separated by a partition wall. The environmental simulation system includes a water level control module, a wave-generating module 6, and a water quality maintenance module 8. The water level control module is used to regulate the water level of the main water tank 1. The wave-generating module 6 is set in the main water tank 1 and is used to generate simulated ocean waves in the main water tank 1. The water quality maintenance module 8 is used to maintain the water quality in the main water tank 1. The component holding system is used to apply a continuous load to the test component 10 set in the main water tank 1. The monitoring system is used to collect environmental parameters in the main water tank 1 and state parameters of the test component 10 in real time. The control system 5 is communicatively connected to the environmental simulation system, the component holding system, and the monitoring system, and is used to control the operation of the environmental simulation system and the component holding system, and to receive and process data from the monitoring system. The power supply system includes an independent power generation module, an energy storage module 4, and a power supply module 18. The power generation module is a new energy power generation device, and its output end is electrically connected to the energy storage module 4. The output end of the energy storage module 4 is electrically connected to the monitoring system and the control system 5. The power supply module 18 is a mains power interface or a high-power power supply, and its output end is electrically connected to the environmental simulation system and the component support system.

[0032] In the marine environmental corrosion testing equipment with self-generating power and adaptable to multi-scenario, multi-parameter intelligent monitoring provided in this application embodiment, the wave-generating module 6 can generate water flow motion that simulates real ocean waves in the main water tank 1; the component holding system can apply continuous load to the test component 10, restoring the structural stress borne by the marine engineering test component 10 during service; the water level control module, through the coordinated work of the opening and closing device and the water pump 7, realizes the periodic rise and fall of the water level in the main water tank 1, accurately simulating the dry and wet cycle effect brought about by the ebb and flow of tides; the water quality maintenance module 8 maintains the stability of parameters such as microorganisms in the liquid in the main water tank 1, matching the water quality characteristics of different sea areas. It can integrate wave generation, holding, dry and wet cycle, and water quality control functions into one. Under the synergistic effect of multiple functions, the equipment can reproduce the complex environment of different marine scenarios such as nearshore, deep sea, and intertidal zone, making the test data more consistent with the actual service conditions of the components, and providing a more reliable basis for the corrosion resistance design of marine engineering materials and structures. The monitoring system collects environmental parameters and state parameters of the test component 10 in real time within the main water tank 1. The control system 5 receives and processes the data from the monitoring system. The monitoring and control systems work together to monitor and process data in real time, ensuring data continuity and providing a more reliable basis for the corrosion-resistant design of marine engineering materials and structures. The environmental simulation system and component support system are high-energy-consuming modules, which can meet their high-power requirements by being powered by mains electricity or a high-power power supply. The monitoring and control systems 5, however, have lower energy consumption and can be powered by a new energy power generation module. This zoned power supply mode of "high-energy-consuming modules powered by mains electricity + low-energy-consuming modules powered by new energy" reduces the power configuration of the new energy power generation devices, lowering the initial cost of the equipment; it also reduces mains electricity consumption, achieving energy conservation and emission reduction. Furthermore, the power supply from the new energy power generation module to the monitoring and control systems 5 ensures that the parameters of the test component 10 and the environment can be collected by the monitoring system and analyzed by the control system 5 under all circumstances, ensuring no data loss and achieving full life-cycle data acquisition. The control system 5 is used to control the operation of the environmental simulation system and the component holding system, so as to realize the automatic control of environmental parameters and the load of the test component 10, reduce the dependence on manual operation, and improve the degree of automation.

[0033] It should be noted that new energy power generation is greatly affected by natural conditions (such as solar power generation being affected by day and night and weather, and wind power generation being affected by wind strength). The energy storage module 4 can store the excess electricity generated by the power generation module during peak periods (such as when there is plenty of sunshine at noon or when there is strong wind) and release it during off-peak periods (such as at night or when there is no wind), ensuring the stable power supply of the monitoring system and control system 5 and avoiding power outages caused by fluctuations in new energy power generation.

[0034] In some embodiments, the power generation module includes at least one of a solar power generation unit 3 and a wind power generation unit. The solar power generation unit 3 includes an array of solar panels installed on top of the pool body; the wind power generation unit includes a wind power supply module 18.

[0035] In the above embodiment, the solar panel array is laid on top of the pool body, making full use of the unused space above the pool body without occupying additional ground area. At the same time, the reflective effect of the pool surface can help improve the light-gathering efficiency of the solar panels (especially in sunny weather), ensuring stable power output. The wind power generation unit (such as a small wind turbine) can utilize the natural wind resources of the test scenario such as islands and coastlines, complementing solar power generation. On cloudy days or at night, wind power generation can make up for the shortcomings of solar power generation, ensuring the continuous power supply capability of the power generation module and improving the stability of new energy utilization.

[0036] Please refer to Figure 1 In some embodiments, an overflow hole 11 is provided on the partition wall, and the water level control module includes an opening and closing device and a water pump 7. The opening and closing device is sealed in the overflow hole 11 and is configured to allow liquid in the main water tank 1 to flow into the storage tank 2 through the overflow hole 11 when opened, thereby lowering the water level in the main water tank 1. The water pump 7 is configured to pump liquid from the storage tank 2 into the main water tank 1, thereby raising the water level in the main water tank 1.

[0037] In the above embodiment, the water level control module, through the coordinated operation of the opening and closing device and the water pump 7, realizes the periodic rise and fall of the water level in the main water tank 1, accurately simulating the dry and wet cycle effect brought about by the ebb and flow of tides.

[0038] In some embodiments, the opening and closing device includes an actuator 20 and a seal. The seal is in a sealing engagement with the overflow orifice 11, and the actuator 20 is configured to drive the seal to move relative to the overflow orifice 11 to open or close the overflow orifice 11.

[0039] In the above embodiments, the actuator 20 (such as an electric push rod or a cylinder) can precisely drive the seal. By controlling the parameters set by the control system 5 (such as opening and closing stroke and speed), the opening degree of the overflow hole 11 is precisely controlled, thereby realizing the step-like adjustment or uniform rise and fall of the water level in the main water tank 1, meeting the precise requirements for the dry-wet cycle rate under different test scenarios (such as simulating rapid dry-wet alternation in the intertidal zone and slow water level changes in the deep sea). At the same time, the actuator 20 has a short response time and can start instantly after receiving the command from the control system 5, avoiding water level control deviations caused by manual operation delays and ensuring the stability of test conditions.

[0040] In some embodiments, the seal is configured to be inserted into the overflow orifice 11 to close the overflow orifice 11 when driven by the actuator 20, or to be withdrawn from the overflow orifice 11 to open the overflow orifice 11.

[0041] Please refer to Figure 1 In some embodiments, the actuator 20 is disposed on the top of the water storage tank 2, and the opening and closing device also includes a transmission assembly (not shown in the figure), which is connected to the actuator 20. One end of the transmission assembly away from the actuator 20 is connected to the seal, and the transmission assembly is used to transmit the driving force generated by the actuator 20 to the seal.

[0042] In the above embodiment, the sealing element and the overflow hole 11 adopt a customized sealing fit (such as an interference fit between the rubber sealing element and the overflow hole 11). Compared with the traditional gap seal, this can effectively prevent liquid leakage from the gap between the overflow hole 11 and the sealing element, ensuring the stability of the water level in the main water tank 1 under sealed conditions and preventing the disruption of the wet-dry cycle due to leakage. In addition, the material of the sealing element can be selected according to the corrosiveness of the test liquid (such as high-salt seawater, acidic seawater) to select corrosion-resistant materials (such as fluororubber, polytetrafluoroethylene), extending the service life of the opening and closing device and reducing maintenance costs.

[0043] In some embodiments, the seal includes a plug and a stop, the stop protruding radially outward from the plug; when the plug is inserted into the overflow hole 11, the stop abuts against the wall surface of the partition wall facing the main water tank 1 and surrounding the overflow hole 11.

[0044] In the above embodiment, when the plug is inserted into the overflow hole 11, the abutment can abut against the wall surface of the partition wall facing the main water tank 1. On the one hand, this provides axial restraint for the seal, preventing the actuator 20 from over-driving and causing the plug to be inserted too deeply, damaging the overflow hole 11 or the seal. On the other hand, the tight fit between the abutment and the partition wall can form a "secondary seal." Even if there is slight leakage in the fit between the plug and the overflow hole 11, the abutment can prevent liquid from flowing from the surface of the partition wall, further improving the sealing reliability. The tight fit between the abutment and the partition wall allows the partition wall to abut against the supporting part, preventing the seal from moving relative to the partition wall under the pressure inside the main water tank 1.

[0045] Please refer to Figure 1 In some embodiments, there are multiple overflow holes 11, which are distributed at intervals in the height direction of the main water tank 1. There are multiple opening and closing devices, which are set one-to-one with the overflow holes 11, and each opening and closing device can be controlled independently to realize multi-level adjustment of the water level of the main water tank 1.

[0046] In the above embodiment, when the water level of the main water tank 1 is lowered, the opening and closing device can be controlled to open the overflow hole 11 at the corresponding height as needed.

[0047] Please refer to Figure 1In some embodiments, the water quality maintenance module 8 includes an ultraviolet disinfection lamp disposed on the upper part of the main water tank 1, which is used to irradiate and disinfect the liquid in the main water tank 1.

[0048] Ultraviolet (UV) disinfection destroys the DNA structure of microorganisms through ultraviolet light, achieving sterilization and disinfection. The entire process requires no addition of any chemical agents to the water, avoiding any alteration of the test liquid composition (such as salinity and pH) by chemical residues. This ensures that the water quality parameters of the test liquid are consistent with the real marine environment, preventing distortion of test data such as corrosion rate and corrosion morphology due to chemical interference. Simultaneously, it avoids secondary corrosion of the test component 10 by chemical agents (such as the oxidation of metal components by certain disinfectants), ensuring the reliability of the test results.

[0049] In the above embodiment, the ultraviolet disinfection lamp is installed on the upper part of the main water tank 1, which can directly irradiate the liquid in the main water tank 1 in all directions. The disinfection range covers the entire main water tank 1. Compared with the disinfection device installed at the bottom (which is easily blocked by sediment), the disinfection is more thorough and more efficient.

[0050] Meanwhile, the ultraviolet disinfection lamp can be turned on and off in conjunction with the water quality monitoring sensor via the control system 5. When the sensor detects that the microbial content in the water exceeds the standard, the control system 5 automatically turns on the disinfection lamp; it automatically turns off after the standard is met, thus realizing automated control of the disinfection process without manual intervention and reducing the complexity of operation.

[0051] In some implementations, the component holding system is a hydraulic loading system that applies a load (continuous load or cyclic load) to the test component 10 via hydraulic drive.

[0052] Please refer to Figure 1 In the above embodiment, the component holding system includes an oil pump 17 and a hydraulic loading device 9. By controlling the oil pump 17 to apply a preset test duration load to the test component 10 using the hydraulic loading device 9, the actual service load environment of the structure is simulated.

[0053] The hydraulic loading system achieves load output through the pressure regulation of hydraulic oil. It can achieve precise control of the load through components such as proportional relief valve and pressure sensor 16, so as to meet the diverse needs of different test components 10 (such as steel and concrete components) for load size (from a few kN to hundreds of kN) and load type (static continuous load and dynamic alternating load).

[0054] Please refer to Figure 2In some embodiments, the monitoring system includes an environmental parameter sensor group and a component status sensor group. The environmental parameter sensor group, located within the main water tank 1, monitors the liquid environment parameters within the tank. This group includes a temperature sensor 14, a salinity sensor 15, and a flow rate sensor 13. The component status sensor group monitors the status of the test component 10. This group includes a force sensor 16 for monitoring the load level and a fiber Bragg grating sensor 12 for monitoring the corrosion rate of the reinforcing steel within the test component 10. The environmental parameter sensor group (temperature, salinity, and flow rate sensors 13) can capture the dynamic environmental changes of the liquid within the main water tank 1 in real time. The component status sensor group (force sensor 16 and fiber Bragg grating sensor 12) can simultaneously monitor the load and corrosion rate of the component. The data from both groups are linked, stored, and analyzed through the control system 5.

[0055] In the above embodiment, both the temperature sensor 14 and the fiber optic grating sensor 12 embedded inside the test component 10 transmit signals to a dedicated fiber optic demodulator 19 via optical fiber for analysis, and then send the digital signals to the control system 5 to collect and monitor environmental parameters and component status parameters in real time.

[0056] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
