Description

Technical Field

[0001] The present invention relates to the technical field of water pollution control and renewable energy, in particular to a solar power generation device for a pollution control system. Background Art

[0002] In recent years, floating solar power generation systems have become increasingly popular in water environment management due to their advantages, such as conserving land resources and utilizing water cooling to improve power generation efficiency. These systems typically consist of a photovoltaic rack with photovoltaic panels mounted on it and a buoyancy pontoon assembly. Supported by a buoyant pontoon, they are supported on the water surface and provide clean energy for pollution control equipment such as water quality monitoring, aeration and oxygenation, and biological purification. Existing technologies generally use a pontoon structure with a fixed buoyancy design, and the photovoltaic rack is often fixed relative to the water surface.

[0003] However, there are some problems with existing equipment: First, the buoyancy and height adjustment adaptability are insufficient. Most of them use a fixed float design, which cannot adjust the height of the photovoltaic modules relative to the water surface as the water level changes dynamically. At high water levels, they are easily impacted by waves, causing water to enter the photovoltaic panels and short-circuit. At low water levels, they are worn by silt and stones due to their proximity to the lake bottom, resulting in a high equipment failure rate. Second, the ecological synergy is poor. Shading structures such as fixed baffles cannot be dynamically adjusted. In summer, insufficient shading leads to an increased incidence of cyanobacteria blooms, while in winter, excessive shading reduces the survival rate of submerged plants. These problems make it difficult for existing equipment to balance power generation efficiency, ecological governance effects and long-term stability, restricting its large-scale application in complex lake environments. Summary of the Invention

The height of the photovoltaic panels can automatically adjust with water level and waves, preventing water short-circuiting and ice damage. Combining the support of the main pontoon and the auxiliary pontoon, the drive sleeve is driven by water surface fluctuations to drive cyclical motion.

This intermittent wave energy drive requires no external power, reducing operation and maintenance costs. When the photovoltaic support is raised on the mounting platform, the rotating rods deploy outward, expanding the shade area, inhibiting algal photosynthesis, and reducing cyanobacterial blooms. The deployed rotating rods also increase the horizontal projected area of ​​the platform, significantly improving its wind and wave resistance. When the photovoltaic support is lowered on the mounting platform, the rotating rods retract, reducing shading and ensuring photosynthesis of submerged plants. The rotating rod structure and the symmetrical layout of the main pontoon work together to enhance overall stability and reduce the risk of the platform capsizing. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0038] Example 1

[0039] Reference Figures 1 to 5 , which is the first embodiment of the present invention, provides a solar power generation device for a pollution control system.

[0040] Specifically, the photovoltaic assembly 100 includes a photovoltaic panel 101 and a photovoltaic bracket 102 provided at the end of the photovoltaic panel 101;

[0041] The support assembly 200 includes a mounting platform 201. A main float 202 and an auxiliary float 203 are provided at the end of the mounting platform 201. An adjusting component is provided inside the auxiliary float 203. The adjusting component is used to adjust the buoyancy of the auxiliary float 203 according to the water level of the lake. A supporting component is also provided on the end face of the mounting platform 201. The supporting component is affected by the auxiliary float 203 and is used to adjust the absolute height of the photovoltaic bracket 102 above the water surface. When the photovoltaic bracket 102 is raised on the end face of the mounting platform 201, the rotating rod 2018 provided inside the mounting frame 2011 on the side of the mounting platform 201 will open outward.

[0042] The wave energy transmission assembly includes a transmission sleeve 205 hinged to the auxiliary buoy 203, a transmission sleeve 205 sleeved on the outer wall of the transmission block 2043, a limiting post 2055 within the mounting post 2052, and a transmission gear 2045 and an output gear 2047 disposed within the transmission box 204. The limiting post 2055 and the transmission groove 2044 form an "idling-driving" alternating mechanism to convert wave energy into the lifting and lowering power of the support column 206.

[0043] A threaded rod 2062 and a lifting sleeve 2063 are provided inside the support column 206, and the top of the lifting sleeve 2063 is fixed to the photovoltaic support 102;

[0044] The sunshade assembly includes a rotating rod 2018 symmetrically arranged in the installation frame 2011. The rotating rod 2018 is linked to the lifting mechanism of the support column 206 and is deployed outward to form a sunshade when the photovoltaic bracket 102 is lowered. The rotating rod 2018 is made of carbon fiber composite material and has structural stability at wind speeds of ≥10m / s. The horizontal projection area of ​​the sunshade assembly in the fully expanded state is 1.2-1.8 times the area of ​​the installation platform 201

[0045] Among them, the photovoltaic panels 101 are symmetrically fixed on the outer surfaces of both sides of the photovoltaic bracket 102, and the photovoltaic bracket 102 is installed on the upper surface of the mounting platform 201. The photovoltaic panels 101 absorb light energy and convert it into electrical energy, which is then converted into DC power through the solar controller and stored in the battery to power the solar inverter and other DC power-consuming equipment.

[0046] A plurality of working modules are also provided on the lower surface of the installation platform 201 for treating the water quality of the lake and reducing pollutants in the water.

[0047] A plurality of main floats 202 are arranged in an array on the lower surface of the installation platform 201. The main floats 202 provide buoyancy to the installation platform 201 and the photovoltaic bracket 102 on the installation platform 201, so that they are stably placed on the lake surface. At the same time, auxiliary floats 203 are symmetrically arranged on both sides of the installation platform 201. The auxiliary floats 203 are provided with adjustment components inside. The adjustment components are adjusted according to the floating height of the water level in the lake. When the water level rises more, the adjustment components control the buoyancy in the auxiliary floats 203 to increase. The auxiliary floats 203 cooperate with the main floats 202 to raise the installation platform 201 a little higher relative to the lake surface. At the same time, the auxiliary floats 203 are affected by the waves on the lake surface, which will drive the supporting components to move, so that the photovoltaic bracket 102 rises again above the installation platform 201, thereby preventing the waves from impacting the photovoltaic panels 101 and affecting the operation of the photovoltaic panels 101.

[0048] At the same time, when the photovoltaic bracket 102 rises relative to the installation platform 201, the rotating rod 2018 located inside the installation frame 2011 on the side of the installation platform 201 will expand outward. The outward expansion of the rotating rod 2018 can improve the stability of the installation platform 201 and improve its stability in wind and waves.

[0049] Example 2

[0050] Reference Figures 4 to 7 , which is the second embodiment of the present invention, and is implemented based on the previous embodiment.

[0051] Specifically, the adjusting component includes a built-in sleeve 2032 arranged inside the auxiliary float 203, an electric push cylinder 2033 is arranged inside the built-in sleeve 2032 and a piston 2034 is arranged at the axis center of the electric push cylinder 2033, a connecting channel 2035 is provided at the end of the built-in sleeve 2032, and the connecting channel 2035 is connected to the outside of the auxiliary float 203, and the piston 2034 moves inside the built-in sleeve 2032 to adjust the water volume inside the built-in sleeve 2032 and change the buoyancy of the auxiliary float 203.

[0052] The auxiliary buoys 203 are symmetrically arranged on both sides of the installation platform 201 , and the two auxiliary buoys 203 are connected together to keep synchronous movement when affected by wind and waves on the lake surface below the installation platform 201 .

[0053] The built-in sleeve 2032 is fixed inside the auxiliary float 203 and is connected to the outside of the auxiliary float 203 through the connecting channel 2035. There is a closed cavity between the two. The position of the piston 2034 inside the built-in sleeve 2032 is controlled by the electric push cylinder 2033. The water outside the auxiliary float 203 is sucked into the inside of the built-in sleeve 2032 through the movement of the piston 2034, which is used to change the overall buoyancy of the auxiliary float 203. The configuration block 2031 arranged below the auxiliary float 203 is used to increase the gravity of the auxiliary float 203 to prevent the connecting channel 2035 from being above the water level of the lake.

[0054] Preferably, a connecting block 2036 is provided on the outer wall of the auxiliary buoy 203 and a limiting groove 2037 is provided on the end face of the connecting block 2036. A connecting rod 2038 is hinged at the end of the connecting block 2036 and the end of the connecting rod 2038 is limited by the limiting groove 2037. The other end of the connecting rod 2038 is hinged to the transmission sleeve 205.

[0055] Among them, the connecting rod 2038 is symmetrically arranged with two connecting blocks 2036 on the outside of the auxiliary buoy 203, and is hinged to the axis of the outer surface of the auxiliary buoy 203. The limiting groove 2037 on the surface of the connecting block 2036 has a small distance from the outer surface of the end of the connecting rod 2038, so that the connecting rod 2038 can move freely at a small angle on the outer surface of the connecting block 2036. When the auxiliary buoy 203 rises to a certain height or falls to a certain height on the water surface, the top position of the connecting rod 2038 will be stuck in the inner edge of the limiting groove 2037, and then the connecting rod 2038 will be driven by the connecting block 2036 to move up or down with the auxiliary buoy 203.

[0056] A transmission box 204 is provided on the outer wall of the installation platform 201, and the transmission box 204 is connected to the supporting component and drives the supporting component to move. The transmission sleeve 205 is provided on the outer wall of the transmission box 204. The end of the connecting rod 2038 is hinged to the hinged rod 2051 provided on the outer wall of the transmission sleeve 205 and drives the transmission sleeve 205 to move on the outer wall of the transmission box 204 through the hinged rod 2051. The installation platform 201 adopts a combined structure of an aluminum alloy frame and an HDPE float, which is corrosion-resistant and easy to modularly assemble.

[0057] Among them, the transmission box 204 is provided with multiple parts fixed on the outside of the installation platform 201 and connected to the supporting components. The movement of the auxiliary float 203 on the lake surface is transmitted to the supporting components through the transmission box 204, thereby driving the control component to move to lift or lower the photovoltaic bracket 102 above the installation platform 201.

[0058] The transmission sleeve 205 is installed on the outer wall of the transmission box 204 and the surface of the hinged rod 2051 is also provided with a second limit groove identical to the limit groove 2037. The hinged rod 2051 is hinged to one end of the connecting rod 2038. When the connecting rod 2038 is driven by the auxiliary float 203, the other end drives the transmission sleeve 205 to rotate on the outer wall of the transmission box 204 through the hinged rod 2051.

[0059] Since the auxiliary buoy 203 is affected by the waves on the water surface, it will move up and down periodically, thereby driving the transmission sleeve 205 to rotate up and down in a small range outside the transmission box 204.

[0060] A transmission block 2043 is provided on the outer wall of the transmission box 204, and a transmission groove 2044 is opened in the end face array of the transmission block 2043. The transmission sleeve 205 is sleeved on the outer wall of the transmission block 2043, and a mounting column 2052 is provided on the outer wall of the transmission sleeve 205. A limiting column 2055 is movably provided on the inner wall of the mounting column 2052, and the limiting column 2055 cooperates with the transmission groove 2044 to realize one-way ratchet transmission.

[0061] The transmission block 2043 and the transmission gear 2045 are coaxially connected, but the difference is that the transmission block 2043 is inside the external transmission sleeve 205, while the transmission gear 2045 is installed inside the transmission box 204.

[0062] The limiting column 2055 is movably installed inside the mounting column 2052, and the bottom of the limiting column 2055 is inserted into the transmission groove 2044 on the surface of the transmission block 2043. Through the engagement between the limiting column 2055 and the transmission groove 2044, when the hinged rod 2051 drives the transmission sleeve 205 to rotate, the transmission block 2043 rotates synchronously.

[0063] A vertical groove 2053 and a horizontal groove 2054 are provided on the inner wall of the mounting column 2052, and the vertical groove 2053 and the horizontal groove 2054 are connected to each other. A sliding column 2057 is provided on the end face of the limiting column 2055, and the end of the sliding column 2057 extends into the interior of the vertical groove 2053 and slides with it. A second elastic member 2058 is provided on the outer wall of the limiting column 2055, and the second elastic member 2058 is used to push the limiting column 2055 to move in the direction of the transmission block 2043, so that the inclined surface 2056 provided at the end of the limiting column 2055 is engaged with the inner wall of the transmission groove 2044.

[0064] Among them, the vertical groove 2053 and the horizontal groove 2054 are a whole, and the vertical groove 2053 is provided with two ends at the two ends of the horizontal groove 2054. The sliding column 2057 on the surface of the limiting column 2055 slides inside the vertical groove 2053. The second elastic member 2058 arranged on the surface of the limiting column 2055, the other end of which is in contact with the inner wall of the mounting column 2052, is used to push the bottom of the limiting column 2055 to engage with the transmission groove 2044.

[0065] The inclined surface 2056 at the bottom of the limiting post 2055 fits with the surface of the transmission groove 2044. When the limiting post 2055 rotates with the transmission sleeve 205, the inclined surface 2056 slides upward along the transmission groove 2044, causing the limiting post 2055 to separate from the transmission block 2043. At this time, the transmission sleeve 205 drives the limiting post 2055 to idle outside the transmission block 2043 into the next transmission groove 2044. Since the transmission sleeve 205 is driven by the connecting rod 208 to rotate up and down periodically When the transmission sleeve 205 just drove the limiting column 2055 to rotate with one side of the inclined surface 2056 inside fitting with the transmission groove 2044, the transmission sleeve 205 rotates in the opposite direction at this time, so that the other side of the limiting column 2055 is directly fitted with the transmission groove 2044 and drives the transmission block 2043 and the transmission sleeve 205 to rotate a certain distance. After that, the rotation of the transmission sleeve 205 again drives the inclined surface 2056 at the bottom of the limiting column 2055 to fit with the transmission groove 2044 and idle rotation occurs again, and this cycle is repeated.

[0066] Preferably, the end of the limiting column 2055 extends to the outer wall of the mounting column 2052 and a first gear 2059 is provided at the end, an adjustment plate 2041 is provided on the end face of the transmission box 204 and an adjustment rack 2042 is provided at the end of the adjustment plate 2041. When the transmission sleeve 205 passes through the adjustment rack 2042, the first gear 2059 is engaged with the adjustment rack 2042 and drives the limiting column 2055 to rotate on the inner wall of the mounting column 2052.

[0067] Among them, the first gear 2059 is at the top position of the limiting column 2055, and the adjustment plate 2041 on the surface of the transmission box 204 is engaged with the first gear 2059 through the adjustment rack 2042 at the end. When the first gear 2059 rotates with the transmission sleeve 205 outside the transmission sleeve 205, after passing the adjustment rack 2042, it engages with the adjustment rack 2042 and rotates. The sliding column 2057 on the surface of the limiting column 2055 slides from the current vertical groove 2053, passes through the horizontal groove 2054, and enters the inside of another vertical groove 2053. At this time, the limiting column 2055 rotates inside the mounting column 2052, and the inclined surface 2056 at the bottom rotates to the other side to fit the transmission groove 2044.

[0068] In the initial state, the first gear 2059 is below the adjusting rack 2042. At this time, the first gear 2059 is not engaged with the adjusting rack 2042. When the auxiliary float 203 moves upward as the water level rises and the buoyancy increases, the transmission sleeve 205 is driven to rotate by the connecting rod 2038. When the first gear 2059 rotates upward with the transmission sleeve 205 and engages with the adjusting rack 2042, it rotates. After the rotation, the inclined surface 2056 of the limit column 2055 points downward. Therefore, when the auxiliary float 203 fluctuates up and down with the waves, the transmission block 2043 is driven to rotate clockwise through the limit column 2055 to transmit the support component and adjust the height of the photovoltaic bracket 102.

[0069] In summary, when in use, the auxiliary float 203 drives the piston 2034 to move via the electric push cylinder 2033 within the internal sleeve 2032, connects to the outside world through the connecting channel 2035, and draws or discharges external water into the internal sleeve 2032. When the water level rises, the water is discharged to increase buoyancy, and when the water level drops, the water is drawn in to reduce buoyancy, thereby adapting to changes in the lake water level. The lifting and lowering of the auxiliary float 203 is transmitted to the transmission sleeve 205 via the connecting rod 2038 hinged to the outer wall connecting block 2036. The end of the connecting rod 2038 is restricted by the limiting groove 2037. Only after the auxiliary float 203 is raised and lowered to a certain extent, the hinge position of the top of the connecting rod 2038 is locked by the limiting groove 2037, and the connecting rod 2038 is driven to move with the auxiliary float 203. The other end of the connecting rod 2038 drives the transmission sleeve 205 to rotate up and down periodically on the outer wall of the transmission box 204.

[0070] The transmission sleeve 205 is sleeved on the outer wall of the transmission block 2043. The limiting post 2055 in the surface mounting post 2052 is pushed by the second elastic member 2058 to engage with the transmission groove 2044 of the transmission block 2043. When the transmission sleeve 205 rotates, the inclined surface 2056 at the end of the limiting post 2055 slides along the transmission groove 2044 to achieve idling. When the transmission sleeve 205 rotates in the opposite direction, the limiting post 2055 directly engages with the transmission groove 2044, driving the transmission block 2043 to rotate synchronously, forming an intermittent motion of "idling-driving" alternation. When the transmission sleeve 205 is driven by the connecting rod 2038 and rotates upward to a specific position, the first gear 2059 at the end of the limiting post 2055 and the adjustment plate 204 1 is engaged with the adjustment rack 2042 on the surface, and the rotation of the first gear 2059 drives the limit column 2055 to rotate, so that the sliding column 2057 enters the other vertical slot 2053 from the vertical slot 2053 through the horizontal slot 2054, changing the direction of the inclined surface 2056, thereby switching the rotation direction of the transmission block 2043 from clockwise to counterclockwise. According to the rise and fall of the water level, the rotation direction of the transmission block 2043 is changed to drive the support component to move, thereby adjusting the height of the photovoltaic bracket 102.

[0071] Example 3

[0072] Reference Figure 3 、 Figure 5 and Figures 6 to 10 , which is the third embodiment of the present invention, is implemented based on the previous embodiment.

[0073] Specifically, a transmission gear 2045 is provided inside the transmission box 204 , and the transmission gear 2045 rotates synchronously with the transmission block 2043 .

[0074] Preferably, the transmission gear 2045 is also engaged with the transmission gear set 2046 arranged inside the transmission box 204, the outer wall of the transmission gear set 2046 is also engaged with the output gear 2047, and a first elastic member 2048 is provided inside the output gear 2047, and a round ball 2049 is also provided at the end of the first elastic member 2048. The first elastic member 2048 is used to push the round ball 2049 to move toward the axis of the output gear 2047, thereby forming a rolling check structure to reduce the reverse impact of waves.

[0075] Among them, the transmission gear 2045 rotates coaxially with the transmission block 2043 and drives the transmission gear set 2046 to rotate. The transmission gear set 2046 is also engaged with the output gear 2047. The force transmitted by the transmission gear 2045 is transmitted through the transmission gear set 2046 and drives the output gear 2047 to rotate.

[0076] A plurality of first elastic members 2048 are provided in the array of the output gear 2047, and the first elastic members 2048 push the ball 2049 to engage with the transmission shaft, so that the rotation of the output gear 2047 can drive the transmission shaft to rotate, and finally drive the second bevel gear 20410 coaxial with the output gear 2047 to rotate.

[0077] Preferably, the supporting component includes a supporting column 206 and a first bevel gear 2061 is arranged inside the supporting column 206, a second bevel gear 20410 is connected to the axis of the output gear 2047, and the second bevel gear 20410 is meshed with the first bevel gear 2061 and drives the first bevel gear 2061 to rotate, a threaded rod 2062 is provided on the end face of the first bevel gear 2061 and a lifting sleeve 2063 is provided on the outer wall of the threaded rod 2062, and the threaded rod 2062 and the lifting sleeve 2063 adopt self-locking trapezoidal threads to prevent the photovoltaic bracket 102 from sliding down in a static water state.

[0078] Among them, the first bevel gear 2061 is engaged with the second bevel gear 20410. When the second bevel gear 20410 rotates, it is transmitted to the first bevel gear 2061 and drives the threaded rod 2062 to rotate synchronously. A lifting sleeve 2063 is provided on the outer surface of the threaded rod 2062. Through the internal thread cooperation, when the threaded rod 2062 rotates, the lifting sleeve 2063 is driven to rise and fall inside the support column 206, and the inner surface of the support column 206 restricts the lifting sleeve 2063 so that it will not rotate with the threaded rod 2062 and can only move up and down.

[0079] The lifting height of the lifting sleeve 2063 is limited. After the lifting sleeve 2063 pushes the photovoltaic bracket 102 to a certain height, or after it is completely lowered, the lifting sleeve 2063 cannot continue to move. At this time, the first bevel gear 2061 cannot continue to rotate, and the output gear 2047 continues to rotate. At this time, the internal ball 2049 will move backward and squeeze the first elastic part 2048, causing the output gear 2047 to fall off the drive shaft and idle.

[0080] It should be noted that when the photovoltaic bracket 102 is pushed by the lifting sleeve 2063 to move upward on the mounting platform 201, the mounting block 1021 on the outside of the photovoltaic bracket 102 drives the screw 1022 to move upward. Inside the mounting frame 2011, a plurality of rotating rods 2018 are arranged in an array. The rotating rods 2018 are stacked and installed inside the mounting frame 2011. The lowest rotating rod 2018 is connected to the fixing ring 2017, and the fixing ring 2017 is fixed inside the mounting frame 2011 and cannot rotate.

[0081] The upper rotating rod 2018 is connected to the output ring 2015, and a groove 2016 is provided on the upper surface of the output ring 2015. The uppermost rotating rod 2018 is connected to the transmission ring 2013. The transmission ring 2013 is sleeved on the outside of the screw rod 1022 and is affected by the screw rod 1022. At the same time, it is restricted by the mounting plate 2012. When the screw rod 1022 moves upward, the transmission ring 2013 only rotates.

[0082] When the transmission ring 2013 rotates, the bottom protrusion 2014 moves inside the groove 2016 on the upper surface of the output ring 2015 until it touches the other side of the groove 2016, which drives the lower output ring 2015 and the rotating rod 2018 to rotate around the axis. Similarly, the protrusion on the lower surface of the upper output ring 2015 moves inside the groove 2016 on the surface of the lower output ring 2015, and after touching the edge of the groove 2016, it drives the lower output ring 2015 and the rotating rod 2018 to rotate around the axis. Since the lowest fixed ring 2017 does not rotate, when the protrusion 2014 on the lower surface of the output ring 2015 touches the edge of the groove on the upper surface of the fixed ring 2017, the output ring 2015 and the transmission ring 2013 stop rotating.

[0083] At this time, the rotating rod 2018 on the outer wall of the transmission ring 2013 is located inside the other side of the installation frame 2011. As the rotating rod 2018 is unfolded, the internal folding plate opens, forming a shadow covering the surface of the lake.

[0084] In summer, by blocking sunlight, the growth of algae inside the water body can be reduced, and after the rotating rod 2018 is unfolded on the side of the installation platform 201, when the water level rises, the shaking amplitude of the installation platform 201 on the lake surface can be reduced to improve stability.

[0085] In summary, during use, when the transmission block 2043 rotates, the coaxial transmission gear 2045 rotates synchronously, and power transmission is achieved through the meshing transmission gear set 2046, which ultimately drives the output gear 2047 to rotate. The first elastic member 2048 inside the output gear 2047 pushes the ball 2049 to engage the transmission shaft, so that the power is transmitted to the coaxially connected second bevel gear 20410. The second bevel gear 20410 meshes with the first bevel gear 2061 inside the support column 206, converting horizontal rotation into vertical rotation, driving the threaded rod 2062 on the end face of the first bevel gear 2061 to rotate. The threaded rod and the lifting sleeve 2063 are threaded together. Under the limiting action of the support column 206, the lifting sleeve 2063 moves up and down along the support column 206, thereby pushing the photovoltaic bracket 102 to rise or fall.

[0086] When lifting sleeve 2063 reaches its limit, such as when the photovoltaic bracket reaches its highest or lowest position, first bevel gear 2061 cannot rotate further. At this point, output gear 2047 remains driven, and ball 2049 compresses first elastic member 2048, disengaging it from the drive shaft, causing output gear 2047 to idle, thus preventing damage to components due to forced force. As the photovoltaic bracket ascends, its outer mounting block 1021 drives screw 1022 upward, allowing transmission ring 2013, which fits around screw 1022, to rotate only within the constraints of mounting plate 2012. A projection 2014 at the bottom of the transmission ring slides within groove 2016 in output ring 2015, contacting the edge of groove 2016 and driving the lower output ring 2015 and its connected rotating rod 2018 to rotate. The projections on the upper output ring 2015 in turn push on the lower output ring 2015, ultimately causing the multi-layered rotating rod 2018 to deploy outward from within mounting frame 2011.

[0087] When the water level is high in summer, the auxiliary float 203 adjusts the buoyancy through the adjustment component, and cooperates with the support component to adjust the height of the photovoltaic bracket 102 relative to the water surface, maintaining a safe distance from the water surface and utilizing the natural heat dissipation of the water to reduce efficiency loss caused by high temperature.

[0088] When the photovoltaic bracket 102 is lowered, the rotating rod 2018 in the linkage mounting frame 2011 is unfolded outward to expand the sunshade area, inhibit the photosynthesis of algae, and reduce the occurrence of cyanobacteria blooms. After the rotating rod 2018 is unfolded, the horizontal projection area of ​​the platform is expanded, and the tilt amplitude under the impact of wind and waves is reduced. Combined with the symmetrical layout of the main buoy 202 and the auxiliary buoy 203, the overall anti-overturning ability is improved.

[0089] During winter, when the water level is low, auxiliary buoy 203 adjusts its buoyancy, raising the support components relative to the water surface. This prevents debris such as mud and rocks from the lake bottom from colliding with mounting platform 201 or main buoy 202, minimizing the impact of ice on the equipment and reducing maintenance costs. Simultaneously, PV mount 102 lowers, retracting rotating rod 2018 to minimize shading, ensuring adequate sunlight for submerged plants and photosynthesis, thereby contributing to the restoration of the lake's ecosystem.
