Description

Technical Field

[0001] The present invention belongs to the technical field of simulation devices, and in particular relates to a device for simulating marine environment and mineralization of a wind power surface protective layer and a method for using the device. Background Art

[0002] At present, offshore wind power projects are gradually moving towards deep sea areas. Whether it is offshore wind power foundations in nearshore waters or deep sea areas, most of its components (including equipment, foundations, submarine cables, and booster stations, etc.) are made of low-carbon steel materials, especially foundations (towers, steel pipe piles, buoy structures, etc.). At present, the anti-corrosion design of steel components in tidal range and submerged areas mainly adopts anti-corrosion coating technology, sacrificial anode cathodic protection technology, and impressed current cathodic protection technology. According to the survey, the anti-corrosion primer and coating in the deep sea environment are difficult to meet the 28-year anti-corrosion life requirements at one time, especially in the environment under the coupling of high humidity and heat and multiple factors in the South China Sea. Specifically, the anti-corrosion coating has low bonding strength, is prone to local corrosion, and is difficult to solve the problem of marine biological fouling. This greatly reduces the normal service life of offshore wind turbines (at least 25 years). According to statistics, the actual longest service life of the full life cycle of domestic offshore wind power projects has not exceeded 13 years. However, there is currently no effective anti-corrosion technology for the problems of anti-corrosion of steel components in tidal range and submerged areas, which is a technical bottleneck that directly restricts the high-quality operation of offshore wind turbines.

[0003] In addition, the corrosion losses caused by marine microorganisms account for about 20% of the total corrosion losses. Marine microbial fouling is a prominent adhesion corrosion damage problem faced by steel components in tidal range and submerged areas, especially in the high humidity and high heat environment of the South China Sea, where marine microorganisms grow luxuriantly and their adhesion corrosion damage problem is more serious. With the continuous deepening of research on microbial corrosion, researchers have found that under certain conditions, microorganisms can inhibit corrosion to a certain extent, and their anti-corrosion effect is even better than some coatings in a short period of time. Therefore, microbial inhibition of corrosion is expected to become the current marine biological fouling problem for offshore wind power steel components in tidal range and submerged areas. However, the mechanism by which microbial adhesion corrosion accelerates the corrosion failure of steel components in tidal range and submerged areas still puzzles the materials and marine communities, and there is still a lack of effective control technology. This is a major scientific and technological problem that has not been fully recognized and solved by existing technologies. The former mainly reflects the interface binding mechanism of marine fouling organisms on the surface of materials, the influence of biological secretions and the molecular composition of the material surface on the biological attachment behavior, the key control factors of the transition from temporary attachment to permanent attachment of typical organisms, the curing binding mechanism of the adhesives secreted by organisms and the surface of materials, the intrinsic relationship between the surface / interface structure and the interface between organisms and marine environment media and materials, etc. The latter mainly reflects the beneficial utilization of the mineralization mechanism of marine biological secretions on the corrosion protection and repair of steel components. Therefore, a device that can simulate the marine environment and realize the biomineralization protection experiment of service materials is needed. Summary of the invention

Figure 2 This is a schematic diagram of the separation of the environmental chamber and the reaction tank in the device for simulating the marine environment and the mineralization of the wind power surface protection layer of the present invention.

In order to facilitate the movement of the environmental box 10, in one embodiment, a plurality of Forma wheels are provided at the bottom of the environmental box 10.

[0053] Since the interior of the environmental box 10 is a sealed space, it is necessary to ventilate the interior of the environmental box 10 by controlling the ventilation component 20 at irregular intervals, so as to ensure that the temperature and humidity of the interior space of the environmental box 10 are maintained while the gas can be continuously circulated, highly simulating the conditions of seawater in natural space. A filtering and disinfecting mechanism 24 for filtering and disinfection is provided at the inlet and outlet of the ventilation component 20.

In one embodiment, the filtration and disinfection mechanism 24 includes a disinfection box and a plurality of ultraviolet sterilization lamps disposed in the disinfection box. A connection port for communicating with the air outlet pipe 22 or the air inlet pipe 21 is disposed at one end of the disinfection box, and a connecting pipe communicating with the interior of the disinfection box is disposed at the other end of the disinfection box, and filter cotton is disposed in the connecting pipe. The filter cotton plays a filtering role, mainly isolating particulate matter, and the ultraviolet sterilization lamp can achieve a sterilization rate of more than 99.9% for bacteria and fine particles.

[0054] The sterilization assembly 50 is disposed in the environmental box 10, and is used to sterilize the interior of the environmental box 10, ensure that the air inside the environmental box 10 is sterile air, and make the interior of the environmental box 10 a sterile environment. In one embodiment, the sterilization assembly 50 includes a plurality of ultraviolet sterilization lamps, and the plurality of ultraviolet sterilization lamps are arranged at intervals at the top of the environmental box 10. The ultraviolet sterilization lamp can eliminate bacteria and fine particles at a rate of more than 99.9%.

[0055] The lighting assembly is fixedly arranged above the environmental chamber 10, and is used to generate lighting of different intensities, and the light is irradiated into the interior of the environmental chamber 10 through the top of the environmental chamber 10, so as to simulate the lighting in the actual marine environment inside the environmental chamber 10.

[0056] Please refer to Figure 4, Figure 3 This is a front view of the environmental box in the device for simulating marine environment and wind power surface protective layer mineralization of the present invention. The temperature control component 30 is arranged in the environmental box 10, and is used to control the temperature in the environmental box 10. The temperature control range of the temperature control component 30 is 5°C-45°C, so that the temperature in the actual marine environment can be simulated in the environmental box 10, such as the temperature can simulate the microbial environment of the South China Sea and the polar environment.

If the temperature in the first chamber needs to be heated, the heating mechanism 32 is turned on, and the air in the second chamber is heated by the heating mechanism 32, and then the fan mechanism 31 is started. The fan mechanism 31 blows the air in the second chamber from the air outlet 121 to the first chamber. Under the air flow, the air in the first chamber will flow from the return air port 122 to the second chamber, and then be heated by the heating mechanism 32, so as to achieve a circulating heating effect. If the temperature in the first chamber needs to be cooled, the heating mechanism 32 is turned on instead of the refrigeration mechanism 33. In addition, the partition 12 is used to divide the interior of the environmental box 10 into the first chamber and the second chamber. The partition 12 is provided with an air outlet 121 and a return air port 122, which can limit the direction of the airflow, and can prevent the airflow from circulating only near the fan mechanism, so as to ensure that the air inside the environmental box 10 participates in the circulation, thereby ensuring that the temperature inside the environmental box is evenly distributed.

[0060] Please refer to Figure 5 , Figure 5The structure diagram of the reaction pool in the device for simulating the marine environment and the mineralization of the surface protective layer of wind power generation in the present invention. The reaction pool 60 is placed in the environmental box 10 for placing seawater. A bracket 63 for placing the sample is provided in the reaction pool 60. One end of the injection tube extends into the reaction pool through the environmental box. A valve (not shown in the figure) is provided at the other end of the injection tube. A bacteria injection pump (not shown in the figure) is provided on the injection tube. The seawater temperature in the natural environment is affected by the ambient temperature. Because the specific heat capacity of water is large, the seawater temperature will be slightly lower than the ambient air temperature in actual conditions. Compared with the change in ambient temperature, the temperature change of seawater is relatively slow. The atmospheric environment is simulated by the environmental box 10 that can control the temperature and humidity. The environmental box 10 directly controls the air temperature to indirectly change the seawater temperature in the reaction pool 60, which is closer to the actual situation. During the experiment, the sample is placed on the bracket 63 in the reaction pool 60 to avoid contact with the reaction pool 60, thereby avoiding affecting the experimental results. By adding artificially prepared seawater in the reaction pool 60, and adding specific biological strains to the seawater in the reaction pool 60 through the injection tube and the injection pump, the biological conditions in the marine environment are simulated. The time for adding specific biological strains is after the sterilization of the interior of the environmental chamber 10 is completed by the sterilization component 50, the valve and the injection pump are opened, and the activated specific biological strains are injected into the seawater of the reaction tank 60. Since the environment chamber 10 is a sterile environment at this time, the specific biological strains added to the reaction tank will not be contaminated by miscellaneous bacteria, thereby avoiding affecting the experimental results. Specific biological strains are selected according to the specific marine biological environment. In one embodiment, the specific biological strains include Pseudoalteromonas.neustonica, Pseudoalteromonas.Piratica and Pseudoalteromonas.Atlantica.

In one embodiment, the wave-making assembly 90 includes a mounting plate 91, a bearing seat 92, a rotating shaft 93, a wave-making plate 94 and a driving motor 95.

And the wave-making board 94 is connected with a one-way plate 96 by a spring hinge 97. When the wave-making board 94 is pushed forward, the one-way plate 96 follows the wave-making board 94 and pushes forward together. The one-way plate 96 closes the through hole on the wave-making board 94, and when the wave-making board 94 is pulled back, the one-way plate 96 rotates upward under the action of seawater resistance, and the through hole on the wave-making board 94 is opened, so that the area of ​​the wave-making board 94 pushing water when moving forward and backward is different, the working area is large when pushing forward, and the working area is small when pulling back, which is conducive to forming waves. And the speed of the wave-making board 94 can be controlled to be fast when pushing forward and slow when pulling back, which is also conducive to forming waves.
