Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and in particular to an adjustable support structure for assisting in the adjustment of the angle of photovoltaic panels. Background Technology

[0002] Photovoltaic panels are the core equipment that converts solar energy into electrical energy through the photovoltaic effect. The core principle is that when sunlight shines on the surface of a specific material, electrons are excited and form an electric current, thus generating electricity. Photovoltaic panels are widely used in various solar power generation systems, providing clean and pollution-free electricity for residential, industrial, and commercial buildings. This effectively reduces dependence on traditional fossil fuels such as coal and oil, making them a key component in the global energy transition. As a crucial component of photovoltaic (PV) panel installation, the photovoltaic (PV) panel support system's core function is to support and secure the solar panels, while ensuring their stable and reliable operation under various complex environmental conditions. The design of the support system must not only guarantee the safety of the PV panel installation, preventing potential detachment or damage, but also maximize the PV panel's sunlight reception angle through a rational structural design, thereby improving the overall power generation efficiency of the PV power generation system and fully leveraging the energy conversion efficiency of the PV panels.

[0003] However, under strong winds, the photovoltaic support structures that support the photovoltaic panels often cannot withstand the huge wind loads and are prone to deformation, tilting, or even collapse. Such structural deformation or tilting will not only change the installation angle and position of the photovoltaic panels, causing structural damage to the photovoltaic panels themselves and directly affecting their power generation efficiency, but will also further damage the overall stability of the support structure, triggering a chain reaction such as failure of support connectors and structural instability.

[0011] Preferably, the cleaning component includes a circular tube fixed to the bottom of the photovoltaic panel. The circular tube is connected to the stacked airbag via a connecting pipe A.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses gears to drive a reflector to rotate towards or away from the photovoltaic panel, thereby achieving adaptive linkage adjustment of the angle between the photovoltaic panel and the reflector according to seasonal changes and the tilt angle of the photovoltaic panel. This ensures that the reflector always maintains the optimal reflective angle with the photovoltaic panel, further improving photovoltaic power generation efficiency. Simultaneously, when strong winds occur, a wind speed sensor can detect wind speed values ​​in real time, outputting a control signal to drive the motor. During this process, an angle sensor monitors and determines the rotation angle of the photovoltaic panel in real time. When the photovoltaic panel reaches a horizontal position, the angle sensor immediately controls the motor to stop, keeping the photovoltaic panel horizontal. This effectively reduces the wind pressure impact and structural load on the photovoltaic panel and the overall support structure caused by strong winds, preventing the photovoltaic panel from swaying, deforming, or even being damaged in strong winds. Furthermore, the reflector forms a protective layer covering the surface of the photovoltaic panel, effectively preventing sand, dust, and debris carried by strong winds from scratching and abrading the photovoltaic panel surface, achieving dual protection for the photovoltaic panel in strong wind environments.

[0016] 2. This invention involves rotating the photovoltaic panel up and down around the hinge position of the support frame. Based on the difference in solar altitude angle between winter and summer, the tilt angle of the photovoltaic panel is dynamically adjusted to ensure that the panel maintains an optimal incident angle with sunlight, maximizing solar energy reception and effectively improving photovoltaic power generation efficiency. Simultaneously, during the operation of the photovoltaic panel, a reflector concentrates and reflects scattered sunlight onto the light-receiving surface of the panel, further improving light utilization and thus enhancing the overall power generation effect of the photovoltaic panel, achieving highly efficient utilization of solar energy.

[0017] 3. This invention automatically removes dust, debris, and other impurities from the surface of the photovoltaic panel using a scraper, effectively improving the cleanliness of the photovoltaic panel surface and ensuring its light-receiving efficiency. Furthermore, during the reflector's flipping process, the reflector drives the pressing rod to rotate synchronously. When the reflector flips to a state where it is completely in contact with the photovoltaic panel, the pressing rod contacts the exhaust valve and triggers the exhaust valve to open. The gas inside the circular tube is discharged through the exhaust pipe. Under the restoring force of spring B, the magnetic block, magnetic ring, and scraper synchronously return to their original positions. During the reset movement, the scraper wipes and cleans the reflector surface along with the sponge strip, effectively removing dust and stains, further ensuring and improving the reflective efficiency and reflection effect of the reflector.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] See Figures 1 to 8 As shown, the present invention provides an adjustable support structure for assisting in the adjustment of the angle of a photovoltaic panel, including a base 1 and a bracket 2 fixed to the top of the base 1. The mounting component is rotatably connected between two sets of brackets 2. A photovoltaic panel 4 is detachably connected to the mounting component, and a reflective component is rotatably connected to one side of the photovoltaic panel 4. The support adjustment mechanism is located above the base 1 and is connected to the installation components. The support adjustment mechanism includes a guide rail 61 fixed to the surface of the base 1. A lead screw 62 driven by a motor 63 is rotatably installed inside the guide rail 61. A moving block 64 is threadedly connected to the outer wall of the lead screw 62. Connecting rods 65 are fixed to both sides of the moving block 64. A rotating rod 66 is hinged between the connecting rod 65 and the photovoltaic panel 4. The sensing and control component is electrically connected to the support and adjustment mechanism. It is used to detect the external wind force and monitor the flip angle of the photovoltaic panel 4, and to transmit control signals to the support and adjustment mechanism. It should be noted that, for reference Figures 1 to 2As shown, during installation, the base 1 is fixed to a flat cement surface with bolts. The initial angle between the photovoltaic panel 4 and the bracket 2 is preset according to the local seasonal characteristics and the angle of sunlight. When it is necessary to adjust the angle of sunlight received by the photovoltaic panel 4 according to seasonal changes, the motor 63 is started, which drives the lead screw 62 to rotate, thereby driving the moving block 64 to move linearly along the guide rail 61. When the solar altitude angle is large in summer, the motor 63 is controlled to rotate forward, so that the lead screw 62 drives the moving block 64 to move away from the motor 63. The moving block 64 drives the rotating rod 66 to move synchronously through the connecting rod 65. This causes the photovoltaic panel 4 to rotate upwards by 10 to 15 degrees around the hinge position of the bracket 2, increasing the angle between the photovoltaic panel 4 and the bracket 2. This allows the photovoltaic panel 4 to receive sunlight in a posture more suitable for the high solar altitude angle in summer. When the solar altitude angle is lower in winter, the motor 63 is reversed, causing the rotating rod 66 to pull the photovoltaic panel 4 downwards by 10 to 15 degrees around the hinge position of the bracket 2. This dynamically adjusts the tilt angle of the photovoltaic panel 4 according to the difference in solar altitude angle between winter and summer, ensuring that the photovoltaic panel 4 maintains a better incident angle with the sunlight, fully receiving solar energy and effectively improving the photovoltaic power generation efficiency. Meanwhile, during the operation of the photovoltaic panel 4, the reflector 5 installed in conjunction with it can effectively reflect sunlight, concentrating the scattered sunlight onto the light-receiving surface of the photovoltaic panel 4, further improving the light utilization rate, thereby enhancing the overall power generation effect of the photovoltaic panel 4 and realizing the efficient utilization of solar energy.

[0022] The reflective adjustment mechanism is connected to the support adjustment mechanism and the reflective component respectively. It is used to adjust the angle between the reflective component and the photovoltaic panel 4 according to the tilt angle of the photovoltaic panel 4. The reflective adjustment mechanism includes a sleeve A71 fixed to one side of the photovoltaic panel 4. A rack rod 72 is slidably provided in the sleeve A71. A gear 74 that meshes with the rack rod 72 is fixed to one end of the reflective component. A stacked airbag 75 that communicates with the sleeve A71 is fixed between the guide rail 61 and the moving block 64. It should be noted that, for reference Figures 1 to 4As shown, in spring and autumn, the photovoltaic panel 4 and the reflector 5 maintain an optimal 90-degree angle to achieve efficient reflection and utilization of sunlight. In summer and winter, during the angle adjustment process of the photovoltaic panel 4, the moving block 64 moves along the guide rail 61, simultaneously squeezing or stretching the stacked airbag 75. Specifically, in summer, when the photovoltaic panel 4 flips upwards, the moving block 64 moves away from the motor 63 and squeezes the stacked airbag 75. The pressurized gas inside the stacked airbag 75 is transported to the sleeve A71 through the connecting pipe A76, increasing the air pressure inside the sleeve A71 and pushing the rack 72 to move. The rack 72, through its interaction with the gear 74... The meshing transmission drives the reflector 5 to rotate 10 to 15 degrees away from the photovoltaic panel 4. When the photovoltaic panel 4 rotates downward in winter, the moving block 64 moves in the opposite direction and stretches the stacked airbag 75. The air pressure inside the sleeve A71 decreases accordingly. Under the reset action of the spring A73, the rack rod 72 moves back, which in turn drives the reflector 5 to rotate 10 to 15 degrees towards or away from the photovoltaic panel 4 through the gear 74. This achieves adaptive linkage adjustment of the angle between the photovoltaic panel 4 and the reflector 5 with the season and the tilt angle of the photovoltaic panel 4, ensuring that the reflector 5 always maintains the optimal reflective engagement angle with the photovoltaic panel 4, and further improving the photovoltaic power generation efficiency. Meanwhile, when strong winds occur, the wind speed sensor 9 can detect the wind force in real time. When the wind force reaches the set threshold, the wind speed sensor 9 outputs a control signal and drives the motor 63 to operate. The motor 63 drives the lead screw 62 to rotate forward, causing the moving block 64 to move away from the motor 63. The moving block 64 then pushes the mounting frame 3 and the photovoltaic panel 4 to gradually flip to a horizontal state through the rotating rod 66. During this process, the angle sensor 10 monitors and judges the flip angle of the photovoltaic panel 4 in real time. When the photovoltaic panel 4 reaches the horizontal position, the angle sensor 10 immediately controls the motor 63 to stop operating, so that the photovoltaic panel 4 maintains a horizontal posture. By adjusting the photovoltaic panel 4 to a horizontal state, its windward area can be greatly reduced, effectively reducing the wind pressure impact and structural load generated by strong winds on the photovoltaic panel 4 and the overall support structure. This avoids the photovoltaic panel 4 from shaking, deforming, or even being damaged in strong winds, and improves the stability and service life of the overall device in severe weather. In addition, during the process of the photovoltaic panel 4 flipping to a horizontal position, the moving block 64 simultaneously squeezes the stacked airbag 75, causing the gas inside the stacked airbag 75 to enter the sleeve A71 through the connecting pipe A76. The gas pushes the rack rod 72 to move and drives the gear 74 to rotate synchronously with the reflector 5. When the photovoltaic panel 4 flips to a horizontal position, the reflector 5 flips to a state that is in contact with the surface of the photovoltaic panel 4. At this time, the reflector 5 forms a shielding protective layer covering the surface of the photovoltaic panel 4, which can effectively prevent strong winds from carrying sand, dust, debris and other objects to scratch and wear the surface of the photovoltaic panel 4, thus achieving dual protection for the photovoltaic panel 4 in strong wind environments.

[0023] Cleaning component, the cleaning component is installed on photovoltaic panel 4 and connected to bushing A71; The spray assembly is located on one side of the photovoltaic panel 4 and is connected to the water storage component.

[0024] In an optional embodiment, the mounting assembly is a mounting frame 3 rotatably connected between two sets of brackets 2, and the photovoltaic panel 4 is detachably connected to the surface of the mounting frame 3 by bolts.

[0025] In an optional embodiment, the reflective component is a reflector 5 rotatably connected to one side of the photovoltaic panel 4. The reflector 5 is adapted to the shape of the photovoltaic panel 4. Both sides of the photovoltaic panel 4 and the reflector 5 are fixed with hinge seats. A hydraulic rod 11 is provided between the two sets of hinge seats. The reflector 5 is adapted to the shape of the photovoltaic panel 4, which can efficiently reflect sunlight, improve the amount of light received by the photovoltaic panel and the power generation efficiency. The hydraulic rod 11 can provide auxiliary support and limit buffer for the flip angle of the reflector 5 during the rotation adjustment of the reflector 5 with the gear 74, so as to ensure that the reflector 5 is more stable when rotating and does not shake or deviate, thereby improving the stability of the overall structure.

[0026] In an optional embodiment, the sensing and control assembly includes a wind speed detection element fixed to the surface of the base 1 and an angle detection element fixed to the surface of the moving block 64. The wind speed detection element is a wind speed sensor 9, and the angle detection element is an angle sensor 10. Both the wind speed sensor 9 and the angle sensor 10 are electrically connected to the motor 63, and both serve as control signal input components for the motor 63.

[0027] In an optional embodiment, a spring A73 is provided inside the sleeve A71, and the two ends of the spring A73 are fixedly connected to the inner wall of the sleeve A71 and one end of the rack 72, respectively. A connecting pipe A76 connects the stacked airbag 75 and the sleeve A71, and a one-way air inlet valve is provided on the outer wall of the sleeve A71.

[0028] In an optional embodiment, the cleaning component includes a circular tube 81 fixed to the bottom of the photovoltaic panel 4. The circular tube 81 is connected to the stacked airbag 75 through a connecting tube A76. Two sets of symmetrically arranged magnetic blocks 82 are slidably arranged inside the circular tube 81. A magnetic ring 83 is slidably sleeved on the outer wall of the magnetic block 82. The magnetic block 82 and the magnetic ring 83 are magnetically connected. A scraping component is fixed to the side wall of the magnetic ring 83 through a support rod. The scraping component is a scraper 84. The top of the scraper 84 is provided with a flexible wiping component and the bottom is provided with a brush component. The flexible wiping component is a sponge strip 85.

[0029] In an optional embodiment, two sets of springs B86 are provided inside the circular tube 81. One end of each set of springs B86 is fixed to the inner wall of the circular tube 81, and the other end is fixed to one side of the magnetic block 82. A connecting pipe B87 is connected between the reflective adjustment mechanism and the circular tube 81. An exhaust pipe 88 is connected to the outer wall of the circular tube 81. An exhaust control valve is provided at one end of the exhaust pipe 88. The exhaust control valve is an exhaust valve 89. A pressing rod 810 that is pressed and cooperates with the exhaust valve 89 is fixed to one side of the reflective component.

[0030] It should be noted that, for reference Figures 3 to 7 As shown, during the process of the photovoltaic panel 4 flipping to a horizontal state, the rack rod 72 slides along the inside of the sleeve A71 and squeezes the gas inside the sleeve A71. The squeezed gas enters the inside of the circular tube 81 through the connecting pipe B87, causing the air pressure inside the circular tube 81 to gradually increase. The increased air pressure pushes the two sets of magnetic blocks 82 to move in opposite directions, and the spring B86 is compressed accordingly. The magnetic blocks 82 drive the magnetic ring 83 to move synchronously through the magnetic action. The magnetic ring 83 then drives the two sets of scrapers 84 to move along the surface of the photovoltaic panel 4 through the support rod. In turn, the scrapers 84 automatically scrape away the dust, debris and other impurities remaining on the surface of the photovoltaic panel 4, effectively improving the cleanliness of the photovoltaic panel 4 surface and ensuring the light-receiving efficiency of the photovoltaic panel 4. In addition, when the photovoltaic panel 4 flips to its initial position, the moving block 64 drives the stacked airbag 75 to reset, which reduces the air pressure inside the sleeve A71. At this time, under the action of the spring A73, the rack rod 72 is reset. At the same time, when the rack rod 72 moves, a negative pressure is generated inside the sleeve A71, and external gas is drawn in through the one-way valve on the outer wall of the sleeve A71 to replenish the inside of the sleeve A71, making it convenient for the next use. Meanwhile, during the flipping process of reflector 5, reflector 5 will drive the pressing rod 810 to rotate synchronously. When reflector 5 flips to a state where it is completely in contact with photovoltaic panel 4, pressing rod 810 contacts exhaust valve 89 and triggers exhaust valve 89 to open. Gas inside round tube 81 is discharged through exhaust pipe 88. Under the reset force of spring B86, magnetic block 82, magnetic ring 83 and scraper 84 synchronously return to their original positions. At this time, reflector 5 is exactly in contact with photovoltaic panel 4. During the reset movement, scraper 84 can wipe and clean the surface of reflector 5 through sponge strip 85 at its top, effectively removing dust and stains from the surface of reflector 5, further ensuring and improving the reflectivity and reflection effect of reflector 5.

[0031] In an optional embodiment, the spray assembly includes a sleeve B91 fixed to one side of the photovoltaic panel 4, a piston 92 slidably disposed inside the sleeve B91, a spring C93 fixed between the inner wall of the sleeve B91 and one side of the piston 92, a spray pipe 94 communicating with the outer wall of the sleeve B91, a plurality of spray heads 95 being provided on the outer wall of the spray pipe 94, and a water storage component being a water storage tank 96 fixed to the surface of the base 1, with a suction pipe 97 communicating between the water storage tank 96 and the sleeve B91.

[0032] In an optional embodiment, the nozzle 94 is arranged parallel to the surface of the photovoltaic panel 4, and multiple sets of nozzles 95 are distributed at equal intervals. The water spraying direction of the nozzles 95 is towards the surface of the photovoltaic panel 4 and is tilted at 15° to 30°. The purpose is to make the water flow evenly sprayed on the entire light-receiving surface of the photovoltaic panel 4, avoiding dead corners for rinsing and cooling. The tilt angle of 15° to 30° allows the water flow to adhere to the surface of the photovoltaic panel 4 with appropriate force, effectively rinsing surface impurities and enhancing the auxiliary cleaning effect.

[0033] It should be noted that, for reference Figure 8As shown, during the angle adjustment of the photovoltaic panel 4, the moving block 64 simultaneously exerts a squeezing effect on the stacked airbag 75. The compressed gas inside the stacked airbag 75 is then transported to the sleeve B91 through the connecting pipe A76. With continuous gas injection, the air pressure inside the sleeve B91 continuously increases. This increased pressure pushes the piston 92 to move smoothly along the inner wall of the sleeve B91. The moving piston 92 exerts a squeezing force on the water stored inside the sleeve B91, causing the water to enter the nozzle 94 under pressure. The water is then sprayed onto the surface of the photovoltaic panel 4 through the nozzle 95. After a windy day, the wind speed sensor 9 detects that the wind force is below a preset threshold. At this time, the wind speed sensor 9 controls the motor 63, causing the motor 63 to drive the photovoltaic panel 4 to rotate. When the photovoltaic panel 4 rotates to the initial angle, the angle sensor 10 detects a signal and controls the motor 63 to shut off. Simultaneously, when the photovoltaic panel 4 rotates to the initial position, the moving block 64... When the movable stacked airbag 75 resets, the air pressure inside the sleeve B91 decreases. At this time, under the action of the spring C93, the piston 92 resets. Simultaneously, when the piston 92 moves, a negative pressure is generated inside the sleeve B91, and water from the water storage tank 96 is replenished into the sleeve B91 through the suction pipe 97 for future use. On the one hand, the water sprayed on the surface of the photovoltaic panel 4 can quickly remove the heat generated during the operation of the photovoltaic panel 4, effectively cooling and preventing the photovoltaic panel 4 from experiencing a decrease in power generation efficiency and a shortened service life due to long-term high-temperature operation. On the other hand, the sprayed water can pre-wash the dust, debris, and other impurities attached to the surface of the photovoltaic panel 4, softening the impurities and reducing their adhesion to the surface of the photovoltaic panel 4. This assists the scraper 84 in thoroughly scraping away impurities from the surface of the photovoltaic panel 4, further improving the cleanliness of the photovoltaic panel 4 surface, ensuring that the photovoltaic panel 4 can fully receive sunlight, and guaranteeing the stability of its power generation efficiency.

[0034] Working principle: During installation, the base 1 is fixed to a flat cement ground with bolts. The initial angle between the photovoltaic panel 4 and the bracket 2 is preset according to the local seasonal characteristics and the angle of sunlight. When it is necessary to adjust the angle of sunlight received by the photovoltaic panel 4 according to seasonal changes, the motor 63 is started, which drives the lead screw 62 to rotate, thereby driving the moving block 64 to move linearly along the guide rail 61. When the solar altitude angle is large in summer, the motor 63 is controlled to rotate forward, so that the lead screw 62 drives the moving block 64 to move away from the motor 63. The moving block 64 drives the rotating rod 66 to move synchronously through the connecting rod 65, thereby pulling the photovoltaic panel 4 to rotate upward by 10 to 15 degrees around the hinge position of the bracket 2, increasing the angle between the photovoltaic panel 4 and the bracket 2, so that the photovoltaic panel 4 can receive sunlight in a posture more suitable for the high solar altitude angle in summer. When the solar altitude angle is small in winter, the motor 63 is controlled to rotate in reverse, so that the rotating rod 66 pulls the photovoltaic panel 4 to rotate downward by 10 to 15 degrees around the hinge position of the bracket 2. Meanwhile, during the operation of the photovoltaic panel 4, the reflector 5, which is set up in conjunction with it, can effectively reflect sunlight; During spring and autumn, the photovoltaic panel 4 and the reflector 5 maintain an optimal 90-degree angle for efficient reflection and utilization of sunlight. In summer and winter, as the photovoltaic panel 4 adjusts its angle, the moving block 64 moves along the guide rail 61, simultaneously compressing or stretching the stacked airbag 75. Specifically, in summer, when the photovoltaic panel 4 flips upwards, the moving block 64 moves away from the motor 63 and compresses the stacked airbag 75. The pressurized gas inside the stacked airbag 75 is then transported to the sleeve A71 through the connecting pipe A76. Inside, the air pressure inside the sleeve A71 increases and pushes the rack rod 72 to move. The rack rod 72 drives the reflector 5 to rotate 10 to 15 degrees away from the photovoltaic panel 4 through meshing with the gear 74. When the photovoltaic panel 4 rotates downward in winter, the moving block 64 moves in the opposite direction and stretches the stacked airbag 75. The air pressure inside the sleeve A71 decreases accordingly. Under the reset action of the spring A73, the rack rod 72 moves back, and then drives the reflector 5 to rotate 10 to 15 degrees closer to the photovoltaic panel 4 through the gear 74. Meanwhile, when strong winds occur, the wind speed sensor 9 can detect the wind force in real time. When the wind force reaches the set threshold, the wind speed sensor 9 outputs a control signal and drives the motor 63 to operate. The motor 63 drives the lead screw 62 to rotate forward, causing the moving block 64 to move away from the motor 63. The moving block 64 then pushes the mounting frame 3 and the photovoltaic panel 4 to gradually flip to a horizontal state through the rotating rod 66. During this process, the angle sensor 10 monitors and judges the flip angle of the photovoltaic panel 4 in real time. When the photovoltaic panel 4 reaches the horizontal position, the angle sensor 10 immediately controls the motor 63 to stop operating, so that the photovoltaic panel 4 maintains a horizontal posture. In addition, during the process of the photovoltaic panel 4 flipping to the horizontal position, the moving block 64 simultaneously squeezes the stacked airbag 75, so that the gas inside the stacked airbag 75 enters the sleeve A71 through the connecting pipe A76. The gas pushes the rack rod 72 to move and drives the gear 74 to rotate synchronously with the reflector 5. When the photovoltaic panel 4 flips to the horizontal position, the reflector 5 flips to the state of being in contact with the surface of the photovoltaic panel 4. At this time, the reflector 5 forms a shielding protective layer covering the surface of the photovoltaic panel 4. During the process of flipping the photovoltaic panel 4 to a horizontal state, the rack rod 72 slides along the inside of the sleeve A71 and squeezes the gas inside the sleeve A71. The squeezed gas enters the inside of the circular tube 81 through the connecting pipe B87, causing the air pressure inside the circular tube 81 to gradually increase. The increased air pressure pushes the two sets of magnetic blocks 82 to move in opposite directions, and the spring B86 is compressed accordingly. The magnetic blocks 82 drive the magnetic ring 83 to move synchronously through the magnetic action. The magnetic ring 83 then drives the two sets of scrapers 84 to move along the surface of the photovoltaic panel 4 through the support rod. Meanwhile, during the flipping process of reflector 5, reflector 5 will drive the pressing rod 810 to rotate synchronously. When reflector 5 flips to a state where it is completely in contact with photovoltaic panel 4, pressing rod 810 contacts exhaust valve 89 and triggers exhaust valve 89 to open. Gas inside round tube 81 is discharged through exhaust pipe 88. Under the action of spring B86's reset force, magnetic block 82, magnetic ring 83 and scraper 84 synchronously achieve return reset. At this time, reflector 5 is exactly in contact with photovoltaic panel 4. During the reset movement, scraper 84 can wipe and clean the surface of reflector 5 through the sponge strip 85 at its top. During the angle adjustment of the photovoltaic panel 4, the moving block 64 simultaneously exerts a squeezing effect on the stacked airbag 75. The gas inside the compressed stacked airbag 75 is then transported to the inside of the sleeve B91 through the connecting pipe A76. As the gas is continuously injected, the air pressure inside the sleeve B91 continuously increases. The increased air pressure pushes the piston 92 to move smoothly along the inner wall of the sleeve B91. The moving piston 92 exerts a squeezing force on the water flow stored inside the sleeve B91, causing the water flow to enter the nozzle 94 under pressure. Subsequently, the water flow is sprayed onto the surface of the photovoltaic panel 4 through the nozzle 95. After the windy weather, the wind speed sensor 9 detects that the wind force is lower than the preset threshold. At this time, the wind speed sensor 9 controls the motor 63, causing the motor 63 to drive the photovoltaic panel 4 to rotate. When the photovoltaic panel 4 rotates to the initial angle, the angle sensor 10 detects the signal and controls the motor 63 to turn off.
