[0001] This application relates to the field of simulation experiment testing technology, and more specifically, to a device and method for testing the corrosion and fouling resistance of a floating photovoltaic system at sea. Background Technology

[0002] With the rapid development of offshore floating photovoltaic (PV) power generation technology, performance testing of PV modules has become a crucial step in ensuring their long-term stable operation. In the marine environment, PV modules face complex and variable climatic conditions, with fluctuations in sunlight intensity having a particularly significant impact on module performance. Current technologies typically employ simulated sunlight environments to assess the weather resistance of coatings for offshore floating PV modules through light source irradiation.

[0003] However, existing testing equipment often cannot flexibly control the interference of external light on the test when simulating illumination, so that the test results are affected by the fluctuation of illumination, which in turn affects the accurate evaluation of coating performance. Summary of the Invention

[0004] The purpose of this application is to provide a floating photovoltaic anti-corrosion and anti-fouling performance testing device and method, which can reduce the interference of external light on the experiment and improve the testing accuracy.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a floating marine photovoltaic anti-corrosion and anti-fouling performance testing device, comprising: A container containing a test solution for simulating an environment, the container having an opening; A solution environment parameter adjustment module is installed in the container to adjust the environmental parameters of the test solution. A light blocking module is disposed at the opening of the container. The light blocking module has a blocking position and a light-transmitting position at the opening. When the blocking position is in place, it blocks external light from entering the interior of the container. When the light-transmitting position is in place, external light can enter the interior of the container through the opening.

[0006] In an optional implementation, the solution environment parameter adjustment module includes: A heater for heating the test solution, the heater being disposed within the test solution in the container.

[0007] In an optional embodiment, a temperature sensor is provided on the inner wall of the container, and the temperature sensor is separately provided from the heater; The temperature sensor is electrically connected to the first control module, and the temperature sensor sends the acquired temperature of the test solution to the first control module. The first control module is electrically connected to the heater, and the first control module controls the start and stop of the heater according to the obtained test solution temperature.

[0008] In an optional embodiment, a fixing plate is detachably provided on the container, and the heater is disposed on the fixing plate; The number of fixed plates is at least two, and the number of heaters is correspondingly more than two.

[0009] In an optional implementation, the light-blocking module includes: A cover plate, which is slidably installed at the opening of the container, is openable and closable at the opening, and when the cover plate is opened, the light blocking module switches to the light-transmitting position; When the cover is closed, the light blocking module switches to the blocking position, and the opening is closed to block external light from entering the container.

[0010] In an optional embodiment, a guide rail is provided at the opening of the container, and the cover plate is slidably mounted on the guide rail; A traction machine is provided at the guide rail, which is used to pull the cover plate to slide on the guide rail so as to drive the cover plate to open and close.

[0011] In an optional implementation, the solution environment parameter adjustment module further includes: A wave generator, disposed in the container, is used to adjust the wave height and flow rate of the test solution in the container.

[0012] In an optional embodiment, the solution environment parameter adjustment module further includes an ultraviolet light source, which is disposed in the container and used to radiate ultraviolet light into the container; And / or, the solution environment parameter adjustment module further includes a salt spray emitter, which is disposed in the container and is used to release solution spray into the container.

[0013] Secondly, the present invention provides a method for testing the corrosion and fouling resistance of a floating photovoltaic system at sea, comprising: Multiple test workpieces with floats and supports are set up in the test environment. The test workpieces are divided into test group and control group. Anti-fouling coating is applied to the floats of the test workpieces in the test group, and anti-corrosion coating is applied to the supports. Initial sample characteristics of the test workpieces in the test group and control group are obtained.

The second cycle is longer than the first cycle, the first preset time is shorter than the first cycle, and the environmental parameters are not applied at the same time.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] The embodiments of this application provide a device and method for testing the anti-corrosion and anti-fouling performance of a floating photovoltaic system at sea. The method of this application can be implemented by the device of this application.

[0024] In a first aspect, embodiments of this application provide a floating photovoltaic anti-corrosion and anti-fouling performance testing device, including a container 100, a solution environment parameter adjustment module, and a light blocking module.

[0025] like Figure 1 As shown, container 100 has an opening 110. The opening 110 is used to communicate the interior of container 100 with the external environment. Water and equipment from the outside can enter the interior of container 100 through the opening 110.

[0026] Container 100 contains a test solution for simulating an environment, such as seawater or a solution prepared with NaCl. The test solution is used to simulate the seawater environment in which photovoltaic modules are actually used.

[0027] A solution environment parameter adjustment module is installed in container 100 to adjust the environmental parameters of the test solution. Environmental parameters include, for example, temperature, flow rate, pH value, or ultraviolet radiation value.

[0028] The light blocking module is installed at the opening 110 of the container 100. The light blocking module has a blocking position and a light-transmitting position at the opening 110. When it is in the blocking position, it blocks external light from entering the container 100. When it is in the light-transmitting position, external light can enter the container 100 through the opening 110.

[0029] This application, through the setting of a light-blocking module, can block external light from entering the container 100, thereby interfering with the experiment inside the container 100 and improving the accuracy of the test.

[0030] For example, the light-blocking module includes photochromic glass disposed at the opening 110. When it needs to be switched to the blocking position, the photochromic glass turns black or the like to block external light from entering the container 100. However, in other embodiments, the light-blocking module includes a cover detachably mounted at the opening 110 of the container 100. When the cover covers the opening 110, the light-blocking module is in the blocking position; when the cover is retracted from the opening 110, the light-blocking module is in the light-transmitting position.

[0031] For example, the cover includes a flexible roller blind that is wound around a rotating shaft rotatably mounted in the container 100. When it is necessary to switch the light blocking module to the blocking position, the flexible roller blind is unrolled from the rotating shaft to cover the opening 110, thereby closing the opening 110 and blocking external light (e.g., ultraviolet rays) from entering the container 100 through the opening 110. After use, the flexible roller blind is wound back onto the rotating shaft, the opening 110 is opened, and the light blocking module is in the light-transmitting position.

[0032] For example, the flexible roll is made of a flexible material, which is at least one of the following: sponge, silicone, latex, rubber, polyurethane, polystyrene, natural / synthetic fibers, etc.

[0033] Unlike the embodiments described above, where the covering element includes a flexible roller blind, such as Figure 1 As shown, in another embodiment, the cover includes a cover plate 310, which is slidably mounted at the opening 110 of the container 100. The cover plate 310 can be opened and closed at the opening 110. When the cover plate 310 is open, the light blocking module switches to the light-transmitting position.

[0034] When the cover 310 is closed, the light blocking module switches to the blocking position, and the opening 110 is closed to block external light from entering the container 100.

[0035] The light blocking module is set at the opening 110 of the container 100. When in the blocking position, it can block external light from entering the container 100, effectively avoiding interference from external light to the experiment inside the container 100, and improving the accuracy and reliability of the test results.

[0036] To improve the efficiency of the light-blocking module switching between blocking and light-transmitting positions, such as... Figure 1 As shown, in one embodiment, a guide rail 320 is provided at the opening 110 of the container 100, and a cover plate 310 is slidably mounted on the guide rail 320. The cover plate 310 can slide back and forth on the guide rail 320 to switch the light blocking module to a blocking position or a light-transmitting position.

[0037] A traction machine is installed at the guide rail 320. The traction machine is used to pull the cover plate 310 to slide on the guide rail 320 so as to drive the cover plate 310 to open and close.

[0038] The traction device includes a drive motor, a first cable, and a second cable. One end of the first cable and the second cable are connected to the output end of the drive motor, and the other end of the first cable and the second cable are connected to the cover plate 310. The first cable and the second cable extend in different directions to form a ring structure, and each of the first cable and the second cable is half of the ring structure. When the drive motor rotates forward, the first cable is wound around the output shaft and the second cable is released from the output shaft. The first cable pulls the cover plate 310 to move and close the opening 110, thereby switching the light blocking module to the blocking position. When the drive motor rotates in reverse, the first cable is released from the output shaft and the second cable is wound around the output shaft. The second cable pulls the cover plate 310 to move and open the opening 110, thereby switching the light blocking module to the light-transmitting position.

[0039] Unlike the embodiment described above, which includes a drive motor, a first cable, and a second cable, in another embodiment, the traction machine includes a telescopic rod. One end of the telescopic rod is mounted on the container 100, and the other end is connected to the cover plate 310. The telescopic rod extends and retracts, causing the cover plate 310 to move back and forth, thereby switching the light blocking module to either the blocking position or the light-transmitting position.

[0040] For example, telescopic rods include, but are not limited to: hydraulic telescopic rods, pneumatic telescopic rods, electric actuators, threaded screw mechanisms, or linear motors.

[0041] like Figure 1 As shown, in one embodiment, the solution environment parameter adjustment module includes a heater 210, which is used to heat the test solution and is disposed in the test solution in the container 100.

[0042] For example, heater 210 includes, but is not limited to: resistance heater, electromagnetic heater, infrared heater, fuel heater, etc.

[0043] For example, at least two heaters 210 are provided in the container 100, and the at least two heaters 210 are equally spaced in the container 100.

[0044] For example, such asFigure 1 As shown, two heaters 210 are provided. In another embodiment, three heaters 210 are provided. In yet another embodiment, four heaters 210 are provided.

[0045] like Figure 1 As shown, in one embodiment, a temperature sensor 220 is provided on the inner wall of the container 100, and the temperature sensor 220 is separately provided from the heater 210.

[0046] Temperature sensor 220 is electrically connected to the first control module, and the temperature of the test solution acquired by temperature sensor 220 is sent to the first control module.

[0047] A mounting plate 240 is provided on the container 100, and a temperature sensor 220 is mounted on the mounting plate 240.

[0048] The first control module is electrically connected to the heater 210, and controls the start and stop of the heater 210 according to the obtained test solution temperature.

[0049] For example, when the temperature of the test solution is higher than the first preset temperature, the first control module stops the heater 210; when the temperature of the test solution is lower than the first preset temperature, the first control module starts the heater 210. For example, the first preset temperature is a single-point discrete value or a range value.

[0050] For example, the first control module includes, but is not limited to, a central processing unit (CPU), a programmable logic controller (PLC), or an electronic device with logic control functions.

[0051] Temperature sensor 220 is electrically connected to the first control module. Once it acquires temperature data, it can quickly send it to the first control module, achieving rapid data feedback. This rapid feedback mechanism enables the system to respond promptly to temperature changes, helping to maintain the stability of the test solution temperature.

[0052] The first control module automatically controls the start and stop of the heater 210 based on the acquired test solution temperature. When the temperature is higher than the first preset temperature, the heater 210 is automatically stopped to prevent the solution temperature from becoming too high; when the temperature is lower than the first preset temperature, the heater 210 is automatically started to raise the solution temperature. This automated control method requires no manual intervention, greatly improving control efficiency and accuracy, and reducing errors caused by human factors.

[0053] like Figure 1 As shown, in one embodiment, a fixing plate 230 is detachably provided on the container 100, and a heater 210 is provided on the fixing plate 230.

[0054] The number of fixed plates 230 is at least two, and the number of heaters 210 is at least two.

[0055] For example, a heater 210 is installed at one end of the fixing plate 230, and the other end of the fixing plate 230 has a U-shaped structure. The fixing plate 230 is hung on the side wall of the container 100 through the U-shaped structure at the other end, thereby realizing that the fixing plate 230 can be detachably installed on the container 100.

[0056] In another embodiment, a first magnetic chuck is provided on the wall of the container 100, a heater 210 is installed at one end of the fixing plate 230, and a second magnetic chuck is installed at the other end of the fixing plate 230. The first magnetic chuck and the second magnetic chuck are magnetically connected so that the fixing plate 230 can be detachably installed on the container 100.

[0057] In another embodiment, a heater 210 is installed at one end of the fixing plate 230, and a bolt hole is installed at the other end of the fixing plate 230. A bolt groove is provided on the container 100, and bolts are installed in the bolt hole and bolt groove, so that the fixing plate 230 can be detachably installed on the container 100.

[0058] The fixing plate 230 is detachably mounted on the container 100 and can move the heater 210 when the temperature of the test solution is uneven, thereby controlling the temperature of the test solution more stably.

[0059] like Figure 1 As shown, in one embodiment, the solution environment parameter adjustment module further includes a wave generator 410, which is disposed in the container 100 for adjusting the wave height and flow rate of the test solution in the container 100.

[0060] In one embodiment, the solution environment parameter adjustment module further includes an ultraviolet light source, which is disposed in the container 100 and used to radiate ultraviolet light into the container 100.

[0061] For example, an ultraviolet light source is such as an ultraviolet emitter or an ultraviolet laser.

[0062] In one embodiment, the solution environment parameter adjustment module further includes a salt spray emitter, which is disposed in the container 100 and is used to release solution spray into the container 100.

[0063] For example, in one embodiment, the salt spray emitter includes an oscillating assembly, a pump, and a water tank containing a salt solution. The pump draws the salt solution and supplies it to the oscillating assembly, which vibrates to transform the salt solution from a liquid state into a mist state.

[0064] like Figure 1 and Figure 2As shown, in one embodiment, the marine floating photovoltaic anti-corrosion and anti-fouling performance test also includes a test workpiece 500, which is located in the test solution of the container 100. The test workpiece 500 includes a float 510, a counterweight 540, a support 530, and a photovoltaic panel 520. The float 510 floats on the test solution, the support 530 is installed on the float 510, the photovoltaic panel 520 is set on the support 530, and the support 530 supports the photovoltaic panel 520 away from the test solution. The counterweight 540 is connected to the float 510 by a connecting cable.

[0065] like Figure 2 As shown, in another embodiment, multiple floats 510 are provided, and correspondingly, multiple supports 530 and photovoltaic panels 520 are also provided. Adjacent floats 510 are connected by connectors 550.

[0066] Secondly, embodiments of this application also provide a method for testing the corrosion and fouling resistance of a floating photovoltaic system at sea, comprising: S100: Set up multiple test workpieces 500 with floats 510 and supports 530 in the test environment, divide the test workpieces 500 into test groups and control groups, apply an anti-fouling coating to the floats 510 of the test workpieces 500 in the test group, apply an anti-corrosion coating to the supports 530, and obtain the initial sample characteristics of the test workpieces 500 in the test group and control group.

[0067] For example, antifouling coatings include, but are not limited to, silicon-based, fluorocarbon, or biomimetic coating materials.

[0068] For example, anti-corrosion coatings include, but are not limited to, hot-dip galvanizing, epoxy coatings, or stainless steel alloys.

[0069] For example, when specifically acquiring the initial sample characteristics of the test workpiece 500 of the test group and the control group, the test workpiece 500 of the test group and the control group are initially weighed and their surface roughness is measured; for example, the weighing is achieved by an electronic scale and the surface roughness is measured by a laser profilometer.

[0070] S200: The first constant environmental parameter that continuously acts on the 500 coating of the test workpiece in the constructed test environment.

[0071] For example, the first constant environmental parameters are constructed based on the actual conditions of the target sea area where photovoltaic modules need to be installed.

[0072] For example, the first constant environmental parameters include, but are not limited to: the concentration of the test solution, temperature, pH value, marine organism stock per unit volume, ultraviolet intensity, and irradiation cycle.

[0073] For example, the concentration of the test solution can be set by adding sodium chloride or water.

[0074] For example, the temperature of the test solution can be set using a heater 210.

[0075] For example, the pH value of the test solution can be set by adding an acidic or alkaline solute.

[0076] For example, the amount of marine organisms per unit volume in the test solution can be set using water or attached marine organisms. Attached marine organisms include, for example, algal spores (such as seaweed and diatoms) and shellfish larvae.

[0077] For example, the setting of ultraviolet intensity and irradiation period can be achieved using an ultraviolet light source.

[0078] S300: Construct environmental parameters that alternately act on the coating of the test workpiece 500 in the test environment. In the first cycle, the first environmental parameter and the second environmental parameter are alternately input. In the second cycle, the third environmental parameter is input. The third environmental parameter lasts for a first preset time. The second cycle is longer than the first cycle, and the first preset time is shorter than the first cycle. The environmental parameters do not act simultaneously.

[0079] For example, the first operating condition environmental parameters are, for example, the wave height and flow rate of the test solution, wherein the wave height is, for example, 0.5m and the flow rate is, for example, 0.5m / s; the second operating condition environmental parameters are, for example, the wave height and flow rate of the test solution, wherein the wave height is, for example, 0m and the flow rate is, for example, 0m / s; and the third operating condition environmental parameters are, for example, the wave height and flow rate of the test solution, wherein the wave height is, for example, 3m and the flow rate is, for example, 2m / s.

[0080] For example, the first cycle is 24 hours, the second cycle is 168 hours (i.e., one week), and the first preset time is 4 hours to 6 hours.

[0081] In specific implementation step S300, during a 24-hour cycle, the first operating condition environmental parameter and the second operating condition environmental parameter are input alternately. For example, after the first operating condition environmental parameter is used for 6 hours, the second operating condition environmental parameter is input, and after the second operating condition environmental parameter is used for 6 hours, the first operating condition environmental parameter is input and used for 6 hours, and so on. Every 168 hours, the third operating condition environmental parameter is input and used for 4 to 6 hours, or the 168-hour cycle ends after the third operating condition environmental parameter is input and used for 4 to 6 hours.

[0082] S400: Obtain a sample from the test workpiece 500, acquire target sample features based on the sample, and analyze coating performance based on the target sample features.

[0083] In specific implementation step S400, the composition of corrosion products on the surface of workpiece 500 is analyzed and tested after the third working condition environmental parameters are applied. For example, XRD analysis of the corrosion product composition is used.

[0084] In specific implementation step S400, the support 530 is removed on a monthly basis, and the corrosion rate on the support 530 is analyzed. For example, the corrosion rate calculation method based on weight loss is used to calculate the corrosion rate of the coating on the support 530.

[0085] In specific implementation step S400, the surface fouling coverage rate of the float 510 is obtained on a seven-day cycle. For example, image analysis software is used to quantitatively analyze the fouling coverage rate.

[0086] In specific implementation step S400, the amount of attached biomass is obtained on a monthly cycle; for example, attached biomass is obtained from the test workpiece 500 by scraping, drying and weighing, and the amount of biomass per unit area is calculated.

[0087] In specific implementation step S400, the proportion of live attached organisms on the float 510 to the total attached organisms is obtained, and the antibacterial activity of the antifouling coating is analyzed; for example, fluorescent staining is used to distinguish between live and dead attached organisms.

[0088] In specific implementation step S400, after obtaining the characteristics of the target sample, the coating performance is evaluated: Antifouling rating: Grade I (Excellent): Soil coverage <5%, biomass <100g / m².

[0089] Grade II (Good): Coverage rate 5%-20%, biomass 100g / m²-300g / m².

[0090] Level III (Poor): Coverage > 20%, Biomass > 300g / m².

[0091] Corrosion resistance level: Grade A (Excellent): Corrosion rate < 0.01 mm / year, no pitting or cracking.

[0092] Grade B (Good): 0.01mm / year - 0.1mm / year, with slight localized corrosion.

[0093] Grade C (Poor): >0.1 mm / year, indicating significant structural damage.

[0094] In one embodiment, a second constant environmental parameter or a third constant environmental parameter is constructed to continuously act on the test workpiece 500 in the test environment, instead of the operating environment parameters that alternately act on the coating of the test workpiece 500.

[0095] For example, the second constant environmental parameter is: a salt spray environment, wherein the salt spray environment is, for example, a 5% NaCl solution spray environment at 35°C.

[0096] For example, the third constant environmental parameter is 0.7 W / m² ultraviolet irradiation, for example, a UVA-340 lamp can be used.

[0097] Input a second or third constant environmental parameter to verify coating durability.

[0098] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0099] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
