[0027] The development of offshore tidal flat photovoltaic construction platforms is to utilize the vast ocean space for photovoltaic power generation, especially in tidal flats and intertidal zones. These platforms can overcome the problems of limited land resources and strict environmental protection requirements, while also being able to withstand the special challenges brought by the marine environment, such as salt spray corrosion, wind and wave impact, etc.

[0028] At present, the purpose of applying photovoltaic construction platforms on offshore tidal flats is to allow photovoltaic panels to fully contact sunlight and improve power generation efficiency. However, during use, existing platforms are unable to adjust the operating angle of photovoltaic panels according to changes in light and light intensity, resulting in the power generation efficiency of photovoltaic panels being lower than the estimated power generation.

[0029] In order to solve the above technical defects, the inventor provides a photovoltaic construction platform for offshore tidal flats. The present invention is further described in detail below with reference to the accompanying drawings: Embodiment 1: The embodiment of the present invention provides an offshore tidal flat photovoltaic construction platform, including a base 1, on which a light monitoring device, a driving device and a control device are provided; an adjusting device is installed on the top of the driving device and is used to adjust the angle between the photovoltaic panel 10 and the base 1; the control device is electrically connected to the light monitoring device, the driving device and the adjusting device; when the photovoltaic panel 10 on the platform generates electricity, the light monitoring device determines the optimal operating angle of the photovoltaic panel 10 according to the light brightness, and then the control device is used to control the driving device to drive the adjusting device to adjust the operating angle of the photovoltaic panel 10; in this process, the light brightness is monitored in real time by the light monitoring device, and the control device is used to control the adjusting device to automatically adjust the operating angle between the photovoltaic panel and the base 1 according to the light conditions, which can ensure that the photovoltaic panel 10 always faces the optimal angle of direct sunlight, thereby maximizing the capture of the straight line of sunlight and improving the photoelectric conversion efficiency. This dynamic adjustment can significantly increase the power generation of the photovoltaic system, and the effect can meet the expected requirements, which solves the technical defect that the platform of the prior art cannot adjust the operating angle of the photovoltaic panel 10 according to the changes in light and light brightness during use, resulting in the power generation efficiency of the photovoltaic panel 10 being lower than the estimated power generation. In this solution, the driving device includes a mounting frame 2, which is arranged at one end of the base 1, and a power output assembly is provided on the mounting frame 2; the adjusting device includes a first adjusting assembly and a second adjusting assembly, the first adjusting assembly is symmetrically arranged at the top of the mounting frame 2, and the ends of the two first adjusting assemblies are connected to one end of the photovoltaic panel 10; one end of the second adjusting assembly is arranged at the other end of the base 1, and the other end of the second adjusting assembly is rotatably connected to the other end of the photovoltaic panel 10; and the light monitoring device is arranged around the top of the base 1 to form four light monitoring areas, which can automatically identify and locate the area with the greatest light brightness by real-time monitoring of the light brightness in four different directions, and the coordinated work of the power output assembly and the first adjusting assembly and the second adjusting assembly enables the photovoltaic panel 10 to be quickly and accurately adjusted to the optimal angle, ensuring that the photovoltaic panel 10 always faces the direction of the strongest light, thereby maximizing the capture of solar energy and improving power generation efficiency. Specifically, when the light intensity monitoring value in a certain light monitoring area is greater than the light intensity monitoring value in other light monitoring areas, the control device controls the power output component, the first adjustment component and the second adjustment component to cooperate to adjust the angle between the photovoltaic panel 10 and the base 1, and place the photovoltaic panel 10 in the light monitoring area with the largest light intensity monitoring value.

[0030] Furthermore, the power output assembly includes an annular guide unit, a first drive member and a distance monitoring unit. The annular guide unit is arranged on the top of the mounting frame 2, and an annular moving area is formed above the top of the base 1, so that when the photovoltaic panel 10 adjusts the working angle later, it can move around the base 1, so that the photovoltaic panel 10 is always aligned with the brightest light area, thereby improving the power generation efficiency and quality of the photovoltaic panel 10; secondly, the first drive member is arranged at the center of the annular guide unit, and a transmission plate is installed at the driving end of the first drive member. The transmission plate is axially perpendicular to the first drive member and axially parallel to the base 1. A moving block is welded on the end of the transmission plate, and the top of the moving block is aligned with the mounting frame 2. The bottom is fixedly connected to support the mounting frame 2 and the photovoltaic panel 10 on the mounting frame 2; then, the second adjustment component is installed in the annular guide unit, and the distance monitoring unit is arranged outside the annular guide unit, and multiple distance monitoring units are arranged, and the multiple distance monitoring units are respectively located in each light monitoring area, and the main function is to monitor the distance between the moving block; when used, there are four light monitoring areas on the platform, each light monitoring area is located in a different direction and position of the base 1, and these four light monitoring areas, to a certain extent, include all areas on the base 1 where sunlight irradiates; at the same time, because the light brightness and the path of the light beam change with the movement trajectory of the sun and the distribution of clouds Therefore, the light monitoring devices in each light monitoring area monitor different light brightness values. The signals of these different light brightness values ​​are transmitted to the control device, and the light monitoring device with the largest light brightness value is screened out by the analysis and comparison module in the control device. Then, the specific position of the light monitoring device on the base 1 is determined according to the positioning module in the control device; then, the control device controls the first driving member to drive the moving block to slide on the annular guide unit, so that the first adjusting component on the mounting frame 2 drives the photovoltaic panel 10 to perform a circular motion around the center of the base 1; since the moving path planned by the annular guide unit is annular, the moving block will drive the mounting frame The photovoltaic panel 10 on 2 passes through each light monitoring area in turn, and the distance monitoring unit located outside the annular guide unit can determine in which light monitoring area the moving block and the photovoltaic panel 10 are located by monitoring the distance value between it and the moving block; if the moving block drives the photovoltaic panel 10 and does not move to the non-target light monitoring area, the first driving member does not stop driving; if the moving block drives the photovoltaic panel 10 and moves to the target light monitoring area, and the distance monitoring unit located in the area detects that the moving block and the driving end of the distance monitoring unit meet the requirements, the signal is transmitted to the control device, and the control device controls the first driving member to stop driving, so that the photovoltaic panel 10 can generate electricity in this area.During this process, the four light monitoring areas fully cover all areas on the base 1 that may be illuminated by sunlight, ensuring the comprehensiveness and accuracy of the light data, and providing reliable data support for the precise tracking of the photovoltaic panel 10. By analyzing and comparing the light brightness values ​​of each light monitoring area, the area with the highest light brightness can be quickly identified and its specific position on the base 1 can be determined. At the same time, combined with the annular guide unit and the distance monitoring unit, the moving path and stop position of the photovoltaic panel 10 can be accurately controlled to ensure that the photovoltaic panel 10 is accurately aligned with the area with the highest light brightness, maximize the efficiency of capturing solar energy, and improve the production capacity and efficiency of photovoltaic power generation; moreover, this intelligent tracking method can significantly reduce energy waste caused by insufficient light or angle deviation, improve the overall power generation effect, and automatically adjust the angle of the photovoltaic panel according to the light conditions without human intervention; moreover, it can also adapt to light changes in different geographical locations, seasons and weather conditions, and realize flexible adjustment of the angle of the photovoltaic panel 10.

[0031] In this solution, the annular guide unit is a guide rail, specifically a concave guide rail, and is an annular structure, arranged on the top of the base 1. When the moving block slides with the guide rail of the annular structure, it will generate a great friction force, causing the moving block to get stuck in the guide rail; in order to improve the smoothness of the displacement of the moving block in the guide rail, rollers are installed on the two sides of the moving block facing the guide rail; the setting of the rollers allows the moving block to change sliding to rolling when cooperating with the guide rail, rolling on the inner wall of the guide rail, significantly reducing the friction force when the moving block moves in the guide rail, so that the moving block can slide more smoothly in the guide rail, avoiding the occurrence of the stuck phenomenon; and, because the rollers can distribute the load more evenly, the deformation of the guide rail or the deflection of the moving block caused by excessive local pressure is reduced, thereby improving the positioning accuracy and stability of the photovoltaic panel 10 tracking. In addition, the resistance of rolling friction is small, which makes the required driving force when the moving block moves in the guide rail also reduced accordingly, thereby reducing energy consumption. The first adjustment component includes an adjustment rod and an adjustment plate. One end of the adjustment rod is detachably connected to the top of the mounting frame 2 through the adjustment plate, and the other end is detachably connected to the bottom of one end of the photovoltaic panel 10. The adjustment rod is specifically an electric push rod. The second adjustment component includes a rotating table, which is symmetrically arranged on the annular guide unit. The rotating table can be divided into a fixed part and a rotating part. The fixed part is welded to the base 1 to improve the firmness of the fixation. The rotating part is installed on the fixed part, and the top of the rotating part is connected to the bottom of the other end of the photovoltaic panel 10 through a wire rope. The light monitoring device is a light sensor or a photoresistor sensor. The embodiment is preferably a light sensor. Through the cooperation of the above-mentioned components, the photovoltaic panel 10 can be moved in each light monitoring area, and the precise positioning of the photovoltaic panel 10 in each light monitoring area is realized, which not only improves the efficiency and capacity of photovoltaic power generation, but also enhances the stability, reliability and maintainability of the system.

[0032] Embodiment 2: In this scheme, the difference from the first embodiment is that the power output assembly also includes a second driving member, a guide unit and a limit rod 30. The second driving member is arranged at one end of the mounting frame 2, and the driving end of the second driving member is connected to the guide unit, and the end of the guide unit extends to the other end of the mounting frame 2; a slider 5 is screwed on the guide unit, and the slider 5 is rotatably connected to the first adjustment assembly; there are two limit rods 30, one end of the two limit rods 30 is rotatably connected to the top of the mounting frame 2, and the other end is movably connected to a sliding rod 31, and the end of the sliding rod 31 is fixedly connected to the bottom of one end of the photovoltaic panel 10, and the limit rod 30 is used to limit the height of the sliding rod 31 inside the limit rod 30; Figure 1-Figure 8 As shown, in this solution, the mounting frame 2 is a frame-type structure, the second driving member is preferably a motor 3, and the guide unit is preferably a reciprocating screw 4; one end of the motor 3 is fixed on the mounting frame 2, and the other end is fixedly connected to the guide unit. The guide fixed unit is screwed with a slider 5. Driven by the motor 3, the slider 5 can perform linear reciprocating motion inside the mounting frame 2. A connecting shaft is installed in the slider 5, and both ends of the connecting shaft are rotatably connected to the first adjustment component; specifically, the first adjustment component includes a support rod 6, one end of the support rod 6 is rotatably connected to the connecting shaft, and the other end is fixed to one end of the mounting plate 8 through a first connecting button 7, and the other end of the mounting plate 8 is rotatably connected to the base 1 through a second connecting button 9. The mounting plate 8 is used to place the photovoltaic panel 10. The mounting plate 8 is provided with a mounting block 11, and a card slot is provided on the left side of the mounting block 11. The right side of the plug block 13 is set as an inclined surface. A No. 1 spring is provided between the plug block 13 and the fixed block 12. The plug block 13 is reset by the No. 1 spring, which plays a balancing auxiliary effect on the movement of the slider 5. Through the combination of the above structures, during the driving process of the motor 3, the slider 5 drives the first adjustment component to rotate, so that the photovoltaic panel 10 is tilted toward the end close to the mounting frame 2, or, tilted toward the end away from the mounting frame 2; the motor 3 serves as a driving force source, and accurately controls the linear reciprocating motion of the slider 5 through the reciprocating screw 4, and then drives the photovoltaic panel 10 to adjust the angle through the connecting shaft and the support rod 6, which is enough to ensure that the photovoltaic panel 10 achieves precise angular positioning during the adjustment process, thereby improving the efficiency of photovoltaic power generation; because the photovoltaic panel 10 can be tilted toward one end close to or away from the mounting frame 2, thereby meeting the angle adjustment requirements under different lighting conditions, the photovoltaic panel 10 can more flexibly adapt to changes in light and improve power generation efficiency. In order to accurately locate the working height of the photovoltaic panel 10 according to the light intensity and the path of the light beam, a limit rod 30 is further provided at the top of the mounting frame 2. The limit rod 30 is located at the rear side of the support rod 6. Two limit rods 30 are provided. One end of the two limit rods 30 is rotatably connected to the top of the mounting frame 2, and the other end is movably connected with a sliding rod 31. The end of the sliding rod 31 is fixedly connected to the bottom of one end of the photovoltaic panel 10. The limit rod 30 is used to limit the height of the sliding rod 31 inside the limit rod 30. The setting of the limit rod 30 provides a precise limit for the height adjustment of the photovoltaic panel 10. By adjusting the height of the sliding rod 31 inside the limit rod 30, the operating height of one end of the photovoltaic panel 10 can be accurately controlled to ensure that the photovoltaic panel 10 can be optimally adjusted according to the light intensity and the beam path, thereby improving the efficiency of photovoltaic power generation; and the limit rod 30 is rotatably connected to the top of the mounting frame 2, providing a stable support point for the photovoltaic panel 10; at the same time, the sliding rod 31 is fixedly connected to the bottom of the photovoltaic panel 10, and the limiting effect of the limit rod 30 effectively prevents the photovoltaic panel 10 from shaking or shifting during the adjustment process, thereby enhancing the stability of the entire system. In this solution, the monitoring device is symmetrically arranged on the top of the base 1 to form two light monitoring areas, and the second driving member is used for the guide unit to drive the first adjustment component and the limit rod 30 to rotate, so that the photovoltaic panel 10 moves to one of the light monitoring areas, or so that the photovoltaic panel 10 moves to another light monitoring area. The setting of two light monitoring areas can divide the light monitoring area into two according to the space size of the on-site environment without changing the position of the light monitoring area. Driven by the second drive member, the photovoltaic panel 10 can quickly move to the light monitoring area with the best lighting conditions according to the real-time monitored light data, so as to maximize the capture and utilization of sunlight and improve the efficiency of photovoltaic power generation. The overall rotation design of the second drive member driving the guide unit, the first adjustment component and the limit rod 30 enables the photovoltaic panel 10 to switch smoothly and quickly between the two light monitoring areas, thereby enhancing flexibility. Furthermore, if Figure 7 and Figure 8As shown, the limit rod 30 is a hollow structure, and a movable opening is opened on one side, and a lifting groove 38 is opened on the movable opening. The lifting groove 38 is composed of a plurality of depressions, and a reset groove 35 is provided at the bottom of the lifting groove 38. The limit shaft 34 is installed in the movable opening, one end of which is located in the depression, and the other end is rotatably connected to a toggle button 33. The toggle button 33 is rotatably connected to one side of the sliding rod 31 near the bottom surface of the movable opening, and a locking button 32 is movably connected to the toggle button 33, and the locking button 32 is also rotatable. It is movably connected to the sliding rod 31 and is located above the toggle button 33; a first torsion spring is provided between the toggle button 33 and the limiting shaft 34, and a second torsion spring is provided between the locking button 32 and the sliding rod 31; a toggle groove 36 and a locking groove 37 are provided on the end of the toggle button 33 away from the limiting shaft 34, and the toggle groove 36 and the locking groove 37 are arranged at intervals; the end of the locking button 32 away from the sliding rod 31 is a plate-like structure, and the plate-like structure is movably connected to the toggle groove 36 or the locking groove 37. In the design of the above structure, since the lifting groove 38 divides the movable opening into different height gears, when the sliding rod 31 is subjected to the gravity of the photovoltaic panel 10 and slides into the limiting rod 30, each movement will achieve the limitation of the sliding rod 31 through the cooperation of the locking button 32 and the toggle groove 36, or the locking button 32 and the locking groove 37; and due to the setting of the first torsion spring and the second torsion spring, the locking button 32 and the toggle button 33 can be reset after the cooperation is completed, so as to achieve the precise adjustment and limitation of the height of the photovoltaic panel 10. Secondly, since the limiting rod 30 is a hollow structure, and the sliding rod 31 is firmly connected to the limiting rod 30 through the limiting shaft 34, the toggle button 33 and the locking button 32 and other components, the load-bearing capacity of the limiting rod 30 is enhanced, and it can bear a larger weight of the photovoltaic panel 10, thereby improving safety.

[0033] Furthermore, since the platform is applied on the sea surface, it will inevitably be washed by the waves, and some impurities will be attached to the top of the photovoltaic panel 10. In order to clean the impurities, the platform also includes a cleaning device, which is electrically connected to the control device. The cleaning device and the photovoltaic panel 10 are both arranged on the top of the mounting plate 8, and the cleaning device is used to clean the top of the photovoltaic panel 10; specifically, Figure 5 and Figure 6As shown, the cleaning device includes a driving motor 21, which is installed on the top of the mounting plate 8. The driving end of the driving motor 21 is connected to a rotating rod 22, and a slide plate 23 is threadedly connected to the rotating rod 22. The slide plate 23 is located above the photovoltaic panel 10, and a brush plate 24 is installed at the bottom of the slide plate 23. A soft brush is provided at one end of the brush plate 24 facing the photovoltaic panel 10; an auxiliary rod 25 is slidably connected to the end of the slide plate 23 away from the rotating rod 22, and both ends of the auxiliary rod 25 are detachably mounted on the other end of the top of the mounting plate 8, parallel to the rotating rod 22; the driving motor 21 serves as a power source to drive the rotating rod 22 to rotate, thereby driving the slide plate 23 and the brush plate 24 at the bottom to move on the surface of the photovoltaic panel 10, so that the soft brush is in close contact with the surface of the photovoltaic panel 10, effectively removing dust, bird droppings and dirt in sea water, and ensuring that the photovoltaic panel 10 maintains a high photoelectric conversion efficiency. Finally, in order to guide the dirt out and avoid it from remaining on the mounting plate 8 and the photovoltaic panel 10, a guide device is provided at the bottom of the cleaning device, and the end of the guide device extends to the outside of the photovoltaic panel 10; the guide device includes a guide groove 27 and a guide plate, and the guide groove 27 is a U-shaped structure, which is horizontally arranged at the bottom of the cleaning device, and its open end faces the cleaning device.
