Description

Technical Field

[0001] This invention relates to a marine protective photovoltaic support structure, suitable for installing photovoltaic equipment at sea. Background Technology

[0002] Offshore photovoltaic (PV) support structures form the framework supporting offshore PV modules. These structures are mainly divided into two types: pile-fixed and floating. Pile-fixed structures use piles (such as steel pipe piles or PHC pipe piles) to fix the support structure to the seabed. Floating structures, on the other hand, use buoyancy devices such as floats to allow the PV array to float on the water surface. When the water depth or silt depth is significant (usually not less than 8 meters), the difficulty and cost of pile-fixing construction increase significantly, making floating structures more economical and feasible.

[0003] Compared to terrestrial environments, the harsh marine environment places higher demands on the stability and durability of the support structure. Among these challenges, sea winds and waves are the main obstacles to the support structure. The enormous wave forces and ocean currents can cause vibrations and fatigue damage to the support structure, leading to twisting or collisions of the photovoltaic support structure, or even causing the entire support structure to overturn. At the same time, the high salinity and high humidity of the marine environment can also accelerate the corrosion of metal components, affecting structural safety and service life, thereby further reducing the overall stability of the photovoltaic support structure. Summary of the Invention

[0004] To overcome the above-mentioned defects, embodiments of the present invention provide a marine protective photovoltaic support structure, which solves the technical problem in the prior art that photovoltaic supports installed in marine environments are prone to vibration and fatigue damage when exposed to harsh marine environments such as sea winds and waves, thus reducing the safety of photovoltaic support use.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A marine protective photovoltaic support structure includes a floating platform, a support bracket fixed on the floating platform, and a support frame mounted on the support bracket for mounting photovoltaic panels. One end of the support frame is hinged to one end of the support bracket via an angle adjustment assembly, and the other end of the support frame is connected to the other end of the support bracket via a flexible support structure. The flexible support structure includes a spring damper and a rigid positioning assembly. The two ends of the spring damper are respectively hinged to the support frame and the support bracket. The rigid positioning assembly includes a sliding frame that can slide within a groove provided on the support bracket and an elastic top member provided on the support bracket that can position and unlock the sliding frame. One end of the sliding frame is hinged to the end of the support frame via a telescopic and rotatable connecting part.

[0006] A further improvement of the technical solution of the present invention is that: the angle adjustment component includes a fixed frame fixedly connected to the end of the support bracket, a limiting bracket that can slide up and down is installed inside the fixed frame, the top of the limiting bracket is hinged to the support frame, and a positioning mechanism is also provided on the fixed frame to position the limiting bracket within the fixed frame.

[0007] A further improvement of the technical solution of the present invention is that the positioning mechanism includes a plurality of positioning holes vertically opened on the limiting bracket and fasteners that are adapted to the positioning holes and are installed on the fixed frame to position the limiting bracket in the fixed frame.

[0008] A further improvement of the technical solution of the present invention is that: the elastic top component includes a sliding rod vertically installed at the end of the bearing support and a limiting spring sleeved on the sliding rod to press the sliding rod down; the lower end of the sliding rod corresponds to the rigid fixing hole on the top surface of the sliding frame; and the upper end of the sliding rod is provided with a guide frame that converts wind power into lift.

[0009] A further improvement of the technical solution of the present invention is that: the flow guide frame is coaxially fixedly installed on the top of the sliding rod, and the flow guide frame is configured with a large curvature on the upper surface and a flat surface on the lower surface, which is used to provide lift when the wind blows.

[0010] A further improvement of the technical solution of the present invention is that: the elastic top member is installed in a vertical cavity on the support bracket; the sliding rod is internally configured as a hollow through groove; an adjusting component for adjusting the pressure of the sliding rod is installed in the through groove; the adjusting component includes an adjusting rod, an adjusting screw fixed below the adjusting rod, and an adjusting nut threadedly engaged with the adjusting screw; the adjusting nut is fixed inside the sliding frame; the sliding frame is located at the lower part of the sliding rod; a limiting spring fitted on the sliding rod is located between the top of the sliding frame and the inner top wall of the cavity; the upper end of the adjusting rod is located inside the guide frame; when the adjusting rod is rotated, the sliding frame moves up and down inside the cavity.

[0011] A further improvement of the technical solution of the present invention is that a positioning column is fixedly installed at the bottom of the sliding frame, and the bottom of the positioning column is set in a round head shape to match the rigid fixing hole on the sliding frame.

[0012] A further improvement of the technical solution of the present invention is that: the cavity is located at the upper part of the slide groove, the rigid fixing hole on the sliding frame is a through hole, and the slide groove is provided with a recess at the position corresponding to the positioning column.

[0013] A further improvement of the technical solution of the present invention is that: the connecting part includes an outer sleeve rod and an inner sleeve rod hinged between the support frame and the sliding frame, the outer sleeve rod and the inner sleeve rod are slidably sleeved together and a positioning member is provided for fixing the relative position of the outer sleeve rod and the inner sleeve rod.

[0014] A further improvement of the technical solution of the present invention is that: the positioning component includes a fixing nut fixed on the outer sleeve rod, a fixing screw threaded with the fixing nut, and a fixing disc located inside the outer sleeve rod. The fixing disc slides radially inside the outer sleeve rod under the drive of the fixing screw, and the fixing disc is rotatably connected to the end of the fixing screw.

[0015] A further improvement to the technical solution of the present invention is that adjacent floating platforms are connected together by a flexible connection structure to form a floating photovoltaic support array.

[0016] A further improvement of the technical solution of the present invention is that: the flexible connection structure includes two mounting seats respectively connected to the sides of adjacent floating platforms, a cylindrical airbag is installed between the two mounting seats, and a chain is also provided between the two mounting seats and inside the cylindrical airbag.

[0017] The technological advancements achieved by this invention due to the adoption of the above technical solutions are as follows: 1. In this invention, when wind passes over the guide frame, it generates an upward lift. When the external wind force reaches a certain level, until the lift generated by the guide frame is sufficient to overcome the self-weight of the guide frame, sliding rod, positioning column, and other structures, as well as the friction between the sliding rod and the supporting bracket and the elastic force of the limiting spring, the positioning column can disengage from the rigid fixing hole. This eliminates the rigid support for the support frame and switches to flexible support from the spring damper, dissipating the impact kinetic energy of the strong wind and preventing the support frame from shaking violently. This allows it to move smoothly and slowly, thus avoiding damage to structures such as photovoltaic panels. When the wind force weakens, the positioning column automatically resets under the action of the limiting spring until it returns to a rigid connection state, ensuring the overall stability of the photovoltaic support system.

[0018] 2. In this invention, by using relevant tools to turn the adjusting rod, the adjusting rod drives the adjusting screw to rotate, thereby adjusting the sliding frame to move along the through groove through the adjusting nut, thereby adjusting the distance between the top of the sliding frame and the top wall of the cavity, and thus adjusting the compression state of the limiting spring, the threshold of the spring can be adjusted so that it can adapt to sea areas with different wind conditions, thereby improving the overall adaptability of the photovoltaic support.

[0019] 3. In this invention, the tilt angle of the photovoltaic panel can be easily adjusted by setting the angle adjustment component to track the optimal solar radiation angle and maximize power generation efficiency. The flexible support structure enables passive automatic switching between two working states of the photovoltaic support: rigid locking under normal conditions and flexible vibration resistance under extreme wind and waves. Flexible protection is only activated under truly dangerous extreme wind and waves, making it more targeted. Furthermore, the rigid positioning component has a simple structure, requiring no reliance on electricity, sensors, or complex control systems, resulting in high reliability and versatility.

Detailed Implementation

[0021] A marine protective photovoltaic support structure includes a floating platform 1, a load-bearing support 2 fixed on the floating platform 1, and a support frame 3 mounted on the load-bearing support 2. The support frame 3 is used to mount and support photovoltaic panels 4. One end of the support frame 3 is hinged to one end of the load-bearing support 2 via an angle adjustment assembly, and the other end of the support frame 3 is connected to the other end of the load-bearing support 2 via a flexible support structure.

[0022] The aforementioned angle adjustment assembly includes a fixed frame 6 that is fixedly connected to or integrally formed with one end of the support bracket 2. A limiting bracket 7 is installed inside the fixed frame 6. The top of the limiting bracket 7 is hinged to the end of the support frame 3. The limiting bracket 7 can slide up and down inside the fixed frame 6 to raise or lower the position of one end of the support frame 3, thereby changing the angle at which sunlight shines on the photovoltaic panel 4 on the support frame 3. A positioning mechanism is also provided on the fixed frame 6 to position the limiting bracket 7 within the fixed frame 6. The positioning mechanism may include several vertically formed positioning holes 9 on the limiting bracket 7 and fasteners 8 installed on the fixed frame 6 that are adapted to the positioning holes 9 to position the limiting bracket 7 within the fixed frame 6.

[0023] The flexible support structure includes a spring damper 5 and a rigid positioning assembly. The two ends of the spring damper 5 are respectively hinged to the support frame 3 and the load-bearing bracket 2; that is, one end of the spring damper 5 is hinged to the bottom of the support frame 3, and the other end is hinged to the top of the load-bearing bracket 2. When the spring damper 5 primarily supports the support frame 3, it also dampens the support frame 3 when it is blown by the wind.

[0024] The rigid positioning assembly includes a sliding frame 12, an elastic top member, and a connecting part. The sliding frame 12 is disposed within a sliding groove 11 provided on the support bracket 2 and can slide within the sliding groove 11. A rigid fixing hole 13 is provided at one end of the top surface of the sliding frame 12. An elastic top member is provided above this rigid fixing hole 13 on the sliding frame 12. The elastic top member is disposed on the support bracket 2 and can position and unlock the sliding frame 12; that is, when the elastic top member is inserted into the rigid fixing hole 13, the sliding frame 12 cannot move; when the elastic top member is disengaged from the rigid fixing hole 13, the sliding frame 12 can slide.

[0025] The connecting part connects the sliding frame 12 and the support frame 3. The connection point with the sliding frame 12 can be located at the end opposite to the rigid fixing hole 13, and the connection point with the support frame 3 is also close to the end of the support frame 3. The connection between the connecting part and both the sliding frame 12 and the support frame 3 is hinged, allowing them to rotate relative to each other and move their relative positions. The connecting part is telescopic and can include an outer sleeve rod 24 and an inner sleeve rod 25 hinged between the support frame 3 and the sliding frame 12. The outer sleeve rod 24 and the inner sleeve rod 25 are slidably sleeved together, and a positioning member is provided between the outer sleeve rod 24 and the inner sleeve rod 25 to fix the relative position of the outer sleeve rod 24 and the inner sleeve rod 25, i.e., the extended length of the outer sleeve rod 24 and the inner sleeve rod 25. The positioning component includes a fixing nut 26 fixed on the outer sleeve 24, a fixing screw 27 threaded with the fixing nut 26, and a fixing disc 28 located inside the outer sleeve 24. The fixing disc 28 slides radially inside the outer sleeve 24 under the drive of the fixing screw 27. The fixing disc 28 is rotatably connected to the end of the fixing screw 27. When the fixing screw 27 is tightened, the fixing disc 28 presses against the inner sleeve 25, so that the elongation length of the outer sleeve 24 and the inner sleeve 25 becomes a fixed length, so that the sliding distance of the sliding frame 12 is specific when it slides with the swing of the support frame 3.

[0026] The elastic top component includes a sliding rod 14 vertically mounted at the end of the support bracket 2. A limit spring 19 is fitted on the sliding rod 14. The elastic force generated by the limit spring 19 can press the sliding rod 14 downward. The lower end of the sliding rod 14 corresponds to the rigid fixing hole 13 on the top surface of the sliding frame 12. When the sliding rod 14 is pressed down, the lower end of the sliding rod 14 enters the rigid fixing hole 13, preventing the sliding frame 12 from sliding. The upper end of the sliding rod 14 is provided with a flow guide frame 16 that converts wind power into lift. The flow guide frame 16 is coaxially fixedly mounted on the top of the sliding rod 14. The flow guide frame 16 is designed with a large curvature on the upper surface and a flat lower surface. When a strong wind blows, the flow guide frame 16 is lifted, causing the sliding rod 14 to generate lift and thus move away from the rigid fixing hole 13 on the top surface of the sliding frame 12, allowing the sliding frame 12 to slide. The elastic top component is installed in a vertical cavity 10 on the support bracket 2. The specific structure of the elastic top member can be such that the interior of the sliding rod 14 is set as a hollow through groove 17, and an adjustment component for adjusting the pressure of the sliding rod 14 (i.e., the threshold at which the rigid positioning component is unlocked) is installed in the through groove 17. The adjustment component includes an adjustment rod 20, an adjustment screw 22 fixed below the adjustment rod 20, and an adjustment nut 23 threadedly engaged with the adjustment screw 22. The adjustment nut 23 is fixed inside the sliding frame 18, which is located at the lower part of the sliding rod 14 and is fitted onto the outside of the sliding rod 14. A limiting spring 19 presses against the top of the sliding frame 18 and the inner top wall (inner top surface) of the cavity 10. The upper end of the adjustment rod 20 is located inside the flow guide frame 16, and the sliding frame 18 moves up and down in the cavity 10 when the adjustment rod 20 is rotated. The present invention also includes a positioning post 15 fixedly installed at the bottom of the sliding frame 18. The bottom of the positioning post 15 is rounded and fits into the rigid fixing hole 13 on the sliding frame 12. The cavity 10 is located above the slide groove 11. The rigid fixing hole 13 on the sliding frame 12 is a through hole, and the slide groove 11 has a recess corresponding to the position of the positioning post 15. A cover 32 for sealing the cavity 10 is provided on the flow guide frame 16 corresponding to the top of the adjusting rod 20.

[0027] When the support frame 3, on which the photovoltaic panels 4 are installed, swings sufficiently under wind force, the elastic top unlocks the sliding frame 12. One end of the support frame 3 is hinged to one end of the support bracket 2, and the other end of the support frame 3 and the support bracket 2 form a flexible connection by a spring damper 5. When the support frame 3 swings, the sliding frame 12 can slide in the groove 11 of the support bracket 2 under the transmission of the connection part, and the spring damper 5 dampens the swing of the support frame 3, so that the support frame 3 and the photovoltaic panels 4 do not vibrate violently. When the wind force is not strong enough and the support frame 3 on which the photovoltaic panels 4 are installed does not need to swing, the elastic top positions the sliding frame 12 so that it no longer slides.

[0028] The adjacent floating platforms 1 of the present invention are connected together by a flexible connection structure to form a floating photovoltaic support array. The flexible connection structure includes two mounting seats 29 respectively connected to the side of the adjacent floating platforms 1, a cylindrical airbag 31 installed between the two mounting seats 29, and a chain 30 is also provided between the two mounting seats 29 and inside the cylindrical airbag 31.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] The marine protective photovoltaic support structure of this embodiment includes a support structure consisting of a floating platform 1 and a supporting support 2. The supporting support 2 is fixed on top of the floating platform 1, as shown below. Figure 1 As shown, several floating platforms 1 are connected together by a flexible connection structure, thus forming a floating photovoltaic support array. It should be further noted that, to ensure the stability of the floating platforms 1, the counterweight can be adjusted by filling the interior of the platforms with water according to different sea conditions in different regions.

[0031] Each photovoltaic support in this embodiment includes a support frame 3, an angle adjustment component, and a flexible support structure. Each support bracket 2 is equipped with a support frame 3, and a photovoltaic panel 4 is mounted on the support frame 3. Each support bracket 2 is also equipped with an angle adjustment component for adjusting the angle position of the support frame 3. The angle adjustment component includes a fixed frame 6 and a positioning mechanism. A fixed frame 6 is fixedly mounted at one end of each support bracket 2. A limit bracket 7 is slidably mounted inside the fixed frame 6. The top of the limit bracket 7 is rotatably connected to the bottom of the support frame 3 on the side away from the spring damper 5. A positioning mechanism is installed between the fixed frame 6 and the limit bracket 7 to fix them together after adjusting the vertical position of the limit bracket 7 within the fixed frame 6.

[0032] It should be added that, before construction, to ensure the smooth implementation of the project, a detailed survey of the water depth and underwater topography is required, and obstacles must be cleared. Simultaneously, the seabed geological conditions (such as soft soil or sand) need to be understood to select and establish a suitable anchoring system (such as counterweight anchoring, special anchorage anchoring, and pile anchoring systems). Then, an installation platform is built on the shore or at the dock, with the submerged portion of the platform having a slope of approximately 10 degrees to facilitate the sliding of the assembled floating units into the water. According to the design requirements, the floating platform 1 and the supporting support 2, which constitute the support structure, are installed together. Then, several floating platforms 1 are installed together using corresponding flexible connection structures to form an array. To improve efficiency and avoid the inconvenience of assembling a large number of floating units at once on land, installation can be carried out between several floating units on the platform. After a portion is installed, it can be pushed halfway into the water, and then the subsequent floating units are installed on the platform until the array is completed. During this process, the photovoltaic panels 4 are installed simultaneously, and the tilt angle of the support frame 3 is adjusted using the angle adjustment components.

[0033] After the assembled floating photovoltaic support array is moved to the predetermined position, the anchor chain connecting plate is fixed in the set position of the floating array. Finally, the anchoring system and the floating array are connected with anchor chains to complete the construction of the floating photovoltaic support array. After debugging and testing, it can be put into use.

[0034] Specifically, during use, when encountering harsh marine environments such as sea winds and waves, to avoid damage to the photovoltaic support system caused by the strong winds and waves, a flexible support structure is used. When encountering strong sea winds, if the wind force is not strong, the wind passing through the flexible support structure will not change its rigid support state. At this time, the support frame 3 and the load-bearing support 2 remain rigidly connected. When the wind force reaches a certain level, the flexible support structure is triggered. At this time, the rigid connection between the support frame 3 and the load-bearing support 2 is broken, and a flexible connection is achieved through the spring damper 5. When a strong wind blows, the spring damper 5 generates huge resistance, dissipating the impact kinetic energy of the strong wind, thereby preventing the support frame 3 from shaking violently and allowing it to move smoothly and slowly, thus avoiding damage to the photovoltaic panels 4 and other structures. When the wind force weakens, the flexible support structure automatically resets until it returns to the rigid connection state, ensuring the overall stability of the photovoltaic support system.

[0035] Meanwhile, the flexible connection structure ensures that when waves pass over the floating photovoltaic support array, several floating platforms 1 can move with the waves, thereby reducing the possibility of rigid impact between the floating platforms 1 and improving the overall stability of the photovoltaic support system.

[0036] During the use of photovoltaic panel 4, the angle of support frame 3 needs to be adjusted according to the actual situation to ensure that photovoltaic panel 4 is in the optimal power generation position. When it is necessary to adjust the angle of support frame 3, the positioning mechanism is released, and then the relative positions of limit bracket 7 and fixed frame 6 are adjusted. After the adjustment is completed, the two are fixed together by the positioning mechanism, and the angle of support frame 3 can be adjusted.

[0037] like Figure 3 , Figure 4 As shown, the positioning mechanism includes fasteners 8 and positioning holes 9. Each fixed frame 6 is equipped with a fastener 8, and the limiting bracket 7 has several positioning holes 9. The arrangement direction of the positioning holes 9 is the same as the sliding direction of the limiting bracket 7. The fasteners 8 are adapted to the positioning holes 9. Specifically, when adjusting the relative position of the limiting bracket 7 and the fixed frame 6, the fastener 8 is removed. After adjusting the relative position, the installation position of the fastener 8 is adapted to one of the positioning holes 9. Then, the fastener 8 is fixed in the positioning hole 9.

[0038] like Figures 3 to 8 As shown, each support bracket 2 is equipped with a flexible support structure, which includes a spring damper 5 and a rigid positioning assembly. Each support bracket 2 is rotatably mounted with a spring damper 5, and the other end of the spring damper 5 is rotatably connected to the bottom of the support frame 3 to provide flexible support. The rigid positioning assembly is used to provide rigid support for the support frame 3. When the sea waves exceed the safety threshold that the support frame 3 can withstand, the rigid positioning is automatically released, and the support is provided by the spring damper 5. The rigid positioning assembly includes a cavity 10, a slide groove 11, a sliding frame 12, a rigid fixing hole 13, and an elastic top member. Each support bracket 2 has a cavity 10 and a slide groove 11 inside. The cavity 10 is located on the upper part of the slide groove 11. A sliding frame 12 is slidably installed inside each slide groove 11. The sliding frame 12 is connected to the support frame 3 through a connecting part. When the support frame 3 swings, the sliding frame 12 can be moved by pushing it through the connecting part. A rigid fixing hole 13 is opened on the sliding frame 12. The rigid fixing hole 13 is located at the lower part of the cavity 10. An elastic top member is installed inside the cavity 10. The lower part of the elastic top member is adapted to the rigid fixing hole 13 to fix the sliding frame 12 in the slide groove 11. The elastic top member can adjust the trigger threshold and automatically trigger when affected by wind and waves.

[0039] Specifically, when the sea breeze blows over the elastic top component, if the wind force is not strong, the elastic top component does not change, thus fixing the position of the sliding frame 12 through the rigid fixing hole 13. At this time, the sliding frame 12 supports the support frame 3 through the connecting part, providing rigid support for the support frame 3. When the wind force reaches a certain level, the elastic top component is triggered. At this time, the elastic top component leaves the rigid fixing hole 13, causing the sliding frame 12 to be in a sliding state, thereby canceling the rigid support for the support frame 3 and changing to flexible support through the spring damper 5. As the wind blows, the spring damper 5 deforms, and the support frame 3 also swings. Through the action of the connecting part, the sliding frame 12 slides in the sliding groove 11 until the wind force decreases, the support frame 3 descends, and the elastic top component resumes its cooperation with the rigid fixing hole 13, thus restoring the rigid support for the support frame 3 and ensuring the overall stability of the photovoltaic support system.

[0040] like Figure 4 , Figure 7 , Figure 8 As shown, the aforementioned elastic top component includes a sliding rod 14, a positioning post 15, a flow guide frame 16, and an adjustment component. Each supporting bracket 2 has a vertical cavity 10, and the sliding rod 14 is located within the cavity 10, allowing it to move up and down within the cavity 10. The sliding rod 14 is a hollow structure with vertical through slots 17 inside. A positioning post 15 is fixedly installed at the bottom of each sliding rod 14. The bottom of the positioning post 15 is a conical structure for easy docking, and the positioning post 15 is adapted to the rigid fixing hole 13. A flow guide frame 16 for converting wind power into lift is coaxially fixedly installed at the top of each sliding rod 14. An adjustment component is fixedly installed inside each sliding rod 14 to adjust the trigger threshold of the sliding rod 14. Specifically, when wind passes through the guide frame 16, it generates an upward lift. The adjustment mechanism provides a threshold for the displacement of the sliding rod 14. When the external wind force reaches a certain level, until the lift generated by the guide frame 16 is sufficient to overcome the self-weight of the guide frame 16, sliding rod 14, positioning column 15, the friction between the sliding rod 14 and the supporting bracket 2, and the elasticity of the adjustment mechanism, the positioning column 15 can disengage from the rigid fixing hole 13, thus eliminating the rigid support for the supporting frame 3. For example... Figure 7 , Figure 8As shown, the aforementioned adjusting components include a through groove 17, a sliding frame 18, an adjusting rod 20, an adjusting screw 22, and an adjusting nut 23. A sliding frame 18 is slidably mounted on each sliding rod 14. A limiting spring 19 is fixedly installed between the top of the sliding frame 18 and the inner top wall of the cavity 10. The limiting spring 19 is fitted on the outside of the sliding rod 14. An adjusting rod 20 is rotatably mounted inside each sliding rod 14. A connector 21 is fixedly installed on the top of the adjusting rod 20. The connector 21 is located inside the flow guide frame 16. An adjusting screw 22 is fixedly installed on the bottom of each adjusting rod 20. The adjusting nut 23 is threaded onto the adjusting screw 22. The adjusting nut 23 is fixedly connected to the sliding frame 18. When the lift generated by the guide frame 16 overcomes the elastic force supported by the limiting spring 19, the limiting spring 19 is compressed, and the sliding frame 18 moves within the cavity 10 until the positioning post 15 disengages from the rigid fixing hole 13, thus canceling the rigid support for the support frame 3. To adapt to sea areas with different wind conditions, the elastic threshold of the spring can also be adjusted. At this time, the adjusting rod 20 is turned with the help of relevant tools, and the adjusting rod 20 drives the adjusting screw 22 to rotate, thereby adjusting the sliding frame 18 to move along the through groove 17 through the adjusting nut 23, thereby adjusting the distance between the top of the sliding frame 18 and the top wall inside the cavity 10, and thus adjusting the compression state of the limiting spring 19, thereby adjusting the threshold (pressure) of the spring.

[0041] like Figure 7 , Figure 8 As shown, the aforementioned flow guide frame 16 is designed with a large curvature on the upper surface and a flat lower surface. When wind blows, the flow guide frame 16 can generate lift. According to Bernoulli's principle, the pressure of a fluid (such as air) changes with its velocity. The faster the flow, the lower the pressure; the slower the flow, the higher the pressure. By designing the upper surface of the flow guide frame 16 with a large curvature, the airflow velocity on the upper surface is faster than that on the lower surface, thus creating a pressure difference between the upper and lower surfaces, thereby generating lift. The top of the flow guide frame 16 is also equipped with a removable cover 32 to protect the connector 21 and reduce damage to the connector 21 from the external environment.

[0042] like Figure 5 , Figure 6As shown, the aforementioned connecting part includes an outer sleeve rod 24, an inner sleeve rod 25, and a positioning component. An outer sleeve rod 24 is rotatably mounted on each sliding frame 12, and an inner sleeve rod 25 is slidably mounted inside the outer sleeve rod 24. The top of the inner sleeve rod 25 is rotatably connected to the bottom of the support frame 3. The positioning component is mounted on the outer sleeve rod 24 to fix the relative position between the outer sleeve rod 24 and the inner sleeve rod 25. In a windy environment, during the process of the spring damper 5 supporting the support frame 3, when the support frame 3 swings, the outer sleeve rod 24 swings on the sliding frame 12, and simultaneously the inner sleeve rod 25 swings with the support frame 3. At this time, the sliding frame 12 moves within the slide groove 11, and the rigid fixing hole 13 on the sliding frame 12 also shifts. To ensure the restoration of rigid support and its stability, the extension lengths of the outer sleeve rod 24 and the inner sleeve rod 25 are adjusted to ensure that the rigid fixing hole 13 is in the working position and can be fixed by the elastic top component.

[0043] like Figure 6 As shown, the positioning component includes a fixing nut 26 and a fixing disc 28. Fixing nuts 26 are fixedly installed on each outer sleeve 24, and fixing screws 27 are threaded onto each fixing nut 26. The fixing disc 28 is slidably installed inside the outer sleeve 24, and the sliding direction of the fixing disc 28 is the same as the axial direction of the fixing screws 27. The fixing disc 28 is rotatably connected to the fixing screws 27. Specifically, when it is necessary to fix the relative position between the outer sleeve 24 and the inner sleeve 25, the fixing screws 27 are turned. Under the action of the fixing nuts 26, the fixing screws 27 push the fixing disc 28 to move until the working end of the fixing disc 28 presses against the inner sleeve 25, thereby fixing the relative position between the outer sleeve 24 and the inner sleeve 25.

[0044] like Figure 9 As shown, the flexible connection structure connecting the floating platforms 1 consists of two mounting bases 29, which are connected by a chain 30. A cylindrical airbag 31 is installed between the two mounting bases 29, and the chain 30 is located inside the cylindrical airbag 31. Specifically, when several floating platforms 1 are installed together to form an array, two floating platforms 1 are first placed together, and then the mounting bases 29 are installed on the corresponding floating platforms 1. The floating platforms 1 are connected together by the chain 30 between the two mounting bases 29 until several floating platforms 1 are connected to form an array. When encountering waves, the cylindrical airbag 31 provides a reaction force to prevent adjacent floating platforms 1 from colliding, thereby improving the overall stability of the floating photovoltaic support array and its ability to resist wind and waves.

[0045] The working principle or usage process of this application is as follows: During the use of the photovoltaic support system, the angle of the support frame 3 needs to be adjusted according to the actual situation to ensure that the photovoltaic panel 4 is in the optimal power generation position. When the angle of the support frame 3 needs to be adjusted, the fastener 8 is removed, and then the relative position of the limiting bracket 7 and the fixed frame 6 is adjusted. After the adjustment, the installation position of the fastener 8 is adapted to one of the positioning holes 9. The two are fixed together by the fastener 8, and the angle adjustment of the support frame 3 is completed. After the angle position of the support frame 3 is adjusted, the rigid fixing hole 13 on the sliding bracket 12 will shift. In order to ensure the stability of the rigid support, the fixing screw 27 needs to be loosened, and the relative position of the outer sleeve rod 24 and the inner sleeve rod 25 needs to be readjusted to ensure that the rigid fixing hole 13 is in the working position. After the adjustment, the fixing screw 27 is tightened. Under the action of the fixing nut 26, the fixing screw 27 pushes the fixing plate 28 to move until the working end of the fixing plate 28 presses against the inner sleeve rod 25, thereby fixing the relative position between the outer sleeve rod 24 and the inner sleeve rod 25. When encountering harsh marine environments such as sea winds and waves, in order to avoid damage to the floating photovoltaic support array caused by the huge wind force and waves, it provides a reaction force through cylindrical airbags 31 to prevent adjacent floating platforms 1 from colliding, thereby improving the overall stability of the floating photovoltaic support array and its ability to resist wind and waves.

[0046] When facing strong winds, the wind passing through the guide frame 16 will generate an upward lift. When the external wind force reaches a certain level, until the lift generated by the guide frame 16 is sufficient to overcome the self-weight of the guide frame 16, sliding rod 14, positioning column 15, the friction between the sliding rod 14 and the bearing support 2, and the elastic force of the limit spring 19, the limit spring 19 is compressed, and the sliding frame 18 moves within the cavity 10 until the positioning column 15 disengages from the rigid fixing hole 13. At this point, the rigid support for the support frame 3 can be canceled, and a flexible connection is achieved through the spring damper 5. When strong winds blow, the spring damper 5 generates huge resistance, dissipating the impact kinetic energy of the strong winds, thereby preventing the support frame 3 from shaking violently and allowing it to move smoothly and slowly, thus avoiding damage to structures such as the photovoltaic panel 4. During the process of the spring damper 5 supporting the support frame 3, when the support frame 3 swings, the outer sleeve rod 24 swings on the sliding frame 12, and at the same time the inner sleeve rod 25 swings with the support frame 3. At this time, the sliding frame 12 slides in the sliding groove 11 until the wind force decreases, the support frame 3 descends, and after the sliding frame 12 slides into place, under the action of the limit spring 19, the positioning column 15 can be automatically re-inserted into the rigid fixing hole 13, restoring the rigid connection state and ensuring the overall stability of the photovoltaic support system.

[0047] To adapt to different sea conditions, the spring's elastic threshold can be adjusted. By using relevant tools to turn the adjusting rod 20, the adjusting rod 20 drives the adjusting screw 22 to rotate, thereby adjusting the sliding frame 18 up and down through the adjusting nut 23. This adjusts the distance between the top of the sliding frame 18 and the inner top wall of the cavity 10, thereby adjusting the compression state of the limiting spring 19. This allows for adjustment of the spring's threshold (pressure), further improving the overall stability of the photovoltaic support system.
