Description

Technical Field

[0001] This invention relates to the field of offshore photovoltaic equipment installation technology, and in particular to a support structure for an offshore wind-resistant photovoltaic platform. Background Technology

[0002] A photovoltaic platform, generally referring to a photovoltaic power generation device, is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy.

[0003] A photovoltaic (PV) system mainly consists of three parts: solar panels (modules), a controller, and an inverter. The main components are electronic devices. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. These modules, along with components such as power controllers, constitute a PV power generation system. To allow PV systems to be installed on the sea surface, they are typically supported by a support structure to ensure they float. However, the harsh marine environment, especially strong winds, typhoons, and their resulting giant waves, poses unprecedented challenges to the support structure of PV platforms.

[0004] The patented technology, disclosed in patent number "CN115955171A", provides a floating photovoltaic device with a damping pool. It is known that the technology enables the damping pool to remain stable due to the high-speed rotation of the wheel when it sways with the waves. This causes the outer and inner fixed rings to rotate, and the first and second trigger posts to contact the first and second conductive plates, respectively, thus enabling the detection of whether the mounting plate is deflected.

[0005] However, the above-mentioned device still has the following problems during use: In order to maximize the power generation efficiency of the photovoltaic panels, the device can maintain the overall stability of the device under the action of waves, reduce the tilting and swaying caused by waves, and ensure that the photovoltaic panels can stably face the sun. However, strong winds often blow in the marine environment. When the wind direction is at a certain angle to the photovoltaic panel, its surface will not only generate huge wind pressure, but also generate strong vortex-induced vibration behind the panel, which will further aggravate the fatigue damage of the structure. At the same time, although the device has the function of controlling the angle adjustment, it cannot automatically and timely change the angle of the photovoltaic panel to reduce the wind-receiving area when the device begins to be subjected to wind pressure. At this time, the impact of the sea wind is entirely borne by the structure, which can easily lead to fatigue or damage at the connection points, seriously reducing the service life of the supporting structure. Summary of the Invention

[0006] The purpose of this invention is to solve the problems mentioned in the background art, and to propose a support structure for offshore wind-resistant photovoltaic platforms.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a support structure for a marine wind-resistant photovoltaic platform, comprising a mounting base and a photovoltaic panel, wherein a rotating ring is slidably connected inside the mounting base, and an inclination adjustment mechanism is provided on the inner wall of the rotating ring, and a downward pressure relief mechanism is provided above the mounting base; The tilt adaptation mechanism includes a movable block located above the rotating ring. When the photovoltaic panel is subjected to weak wind, the movable block moves it slightly to buffer the instantaneous sea wind pressure. When the photovoltaic panel is subjected to strong wind, the movable block rotates the long side of the photovoltaic panel to face the wind direction, reducing wind load and preventing the structure from being damaged by the instantaneous impact of strong wind. A rotating wind-resistant mechanism is provided above the movable block, and the rotating wind-resistant mechanism includes a sliding disk located on the top of the movable block. When the photovoltaic panel is subjected to wind pressure from the sea breeze, the sliding disk is squeezed to move, so that the photovoltaic panel changes its pitch angle around its horizontal axis to parallel the wind direction, thereby reducing the wind-receiving area and wind pressure of the photovoltaic panel while enhancing stability. The downward pressure reduction mechanism includes a connecting frame installed above the mounting base. As the movable block drives the photovoltaic panel to rotate, the synchronous rotation of the connecting frame will drive the photovoltaic panel to move downward towards the sea surface, so that it avoids the strong wind belt above and further reduces the wind pressure.

[0008] Furthermore, the tilt adaptation mechanism includes a connecting frame, and two sliders are slidably connected through the inner wall of the connecting frame. A first fixing rod is slidably connected through the interior of each of the two sliders. A second fixing rod is fixedly connected to the opposite sides of the two sliders. The interior of the movable block is slidably connected to the outer wall of the second fixing rod. A fixing block is fixedly connected through the top of the connecting frame, and a positioning post is slidably connected through the interior of the fixing block. A limit ring is slidably connected to the outer wall of the positioning post, and a first spring is fixedly connected to the top of the limit ring. A tension spring is fixedly connected to one end of the positioning post located inside the connecting frame.

[0009] Furthermore, both ends of the first fixing rod are fixedly connected to the inside of the connecting frame, the outer wall of the limiting ring is slidably connected to the inside of the fixing block, the end of the first spring away from the limiting ring is fixedly connected to the inside of the fixing block, and the end of the tension spring away from the positioning post is fixedly connected to the bottom of the movable block.

[0010] Furthermore, the top of the rotating ring is provided with a circular groove, and the inner wall of the circular groove is provided with several positioning holes. The outer wall of the fixing block is slidably connected to the inner wall of the circular groove, and the outer wall of the positioning post away from the tension spring is inserted into the inner wall of the corresponding positioning hole.

[0011] Furthermore, the rotating wind-resistant mechanism includes a first connecting rod, and the first connecting rod has an internal cavity. A second connecting rod is slidably connected through the inside of the first connecting rod, and the bottom of the second connecting rod is fixedly connected to the top of the sliding disk. The sliding disk has several through holes. A second spring is fixedly connected to the side of the sliding disk away from the second connecting rod. A rotating rod is rotatably connected to the end of the second connecting rod away from the sliding disk. A fixing frame is fixedly installed at the bottom of the photovoltaic panel, and a limit groove is formed inside the fixing frame.

[0012] Furthermore, the bottom of the first connecting rod is fixedly connected to the top of the connecting frame, the outer wall of the sliding disk is slidably connected to the inner wall of the inner cavity, the end of the second spring away from the sliding disk is fixedly connected to the inner wall of the inner cavity, and the outer wall of the rotating rod is slidably connected to the inner wall of the limiting groove.

[0013] Furthermore, the downward pressure relief mechanism includes a fixed column, a torsion spring is fixedly connected to the bottom of the connecting frame, a bidirectional inclined groove is provided on the outer wall of the fixed column, and a protruding rod is fixedly connected to the inside of the connecting frame.

[0014] Furthermore, the interior of the connecting frame is slidably connected to the outer wall of the fixed column, the end of the torsion spring away from the connecting frame is fixedly connected to the top of the mounting base, and the outer wall of the protruding rod is in contact with and slides against the inner wall of the bidirectional inclined groove.

[0015] Compared with existing technologies, the above solution has the following advantages: 1. When the photovoltaic panel is blown by a gentle sea breeze, the photovoltaic panel will cause the movable block to slide along the outer wall of the second fixed rod. At the same time, the second fixed rod will slide along the first fixed rod through the sliders at both ends. This will cause the photovoltaic panel to move several movable blocks in a small range along the wind direction, minimizing the wind pressure on the photovoltaic panel when it is first hit by the sea breeze, greatly smoothing the load, and avoiding damage to the structure due to instantaneous impact. When the photovoltaic panel is blown by strong sea winds, the movable block inside the connecting frame moves to its maximum distance. During this movement, the bottom of the movable block drives one end of the tension spring to move synchronously. Then, the bottom of the positioning column slides along the inner wall of the positioning hole until it disengages. At the same time, it causes the photovoltaic panel to rotate horizontally around the center of the mounting base. The sea wind then applies pressure to the surface of the photovoltaic panel, causing it to eventually rotate to a position where its long side faces the wind, reducing the area exposed to wind pressure. This ensures that the device provides a buffer for the photovoltaic panel when dealing with weak winds. At the same time, when dealing with strong winds, the device automatically maximizes the protection of the main support structure and the photovoltaic panel, significantly improving the service life of the equipment and achieving a fundamental and maximum reduction of wind load.

[0016] 2. As the rotating rod moves up or down, it drives the second connecting rod to move synchronously. Then, the second connecting rod drives the sliding disc to slide along the inner wall of the cavity. Since the cavity is filled with damping oil, the damping oil on one side of the sliding disc moves to the other side of the sliding disc through several through holes during the sliding process. This makes the sliding of the second connecting rod smoother, preventing the support structure and photovoltaic panel from experiencing severe and destructive impacts and shaking under strong winds. This ensures the stability of the entire structure when adjusting the tilt angle. After changing the tilt angle, the photovoltaic panel will be as parallel to the wind direction as possible, adjusting itself to the state of least resistance according to the wind direction, thereby avoiding strong vibrations on the leeward side of the photovoltaic panel and further enhancing stability.

[0017] 3. When the sea breeze blows the photovoltaic panel, causing several fixed blocks to slide, several connecting frames will simultaneously drive the connecting frame to rotate synchronously. Then, the connecting frame will drive the protruding rod to slide along the inner wall of the bidirectional inclined groove. Since the fixed column is fixed above the mounting base, and the bidirectional inclined groove is designed with an angle, the sliding of the bidirectional inclined groove along the protruding rod will cause the connecting frame to move down a certain distance. At the same time, the connecting frame will drive the connecting frame to squeeze the circular groove, causing the circular groove to slide down the inner wall of the rotating ring by the same distance. At this time, the overall height of the photovoltaic panel will also move down with the circular groove, thereby shortening the distance between the photovoltaic panel and the sea surface. Further reducing the height of the photovoltaic panel, which has already been adjusted to a streamlined posture, will lower the center of gravity of the entire photovoltaic panel, thereby avoiding strong winds and further reducing wind pressure.

Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments; generally, the components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations.

[0022] Example 1, please refer to Figures 1-3 A support structure for a wind-resistant photovoltaic platform at sea includes a mounting base 1 and a photovoltaic panel 8. A rotating ring 2 is slidably connected inside the mounting base 1, and an angle adaptation mechanism 3 is provided on the inner wall of the rotating ring 2. A downward pressure relief mechanism 5 is provided above the mounting base 1. A circular groove 6 is opened on the top of the rotating ring 2, and a number of positioning holes 7 are opened on the inner wall of the circular groove 6. The tilt adaptation mechanism 3 includes a movable block 305 set above the rotating ring 2. When the photovoltaic panel 8 is subjected to weak wind, the movable block 305 drives it to move slightly to buffer the instantaneous sea wind pressure. When the photovoltaic panel 8 is subjected to strong wind, the movable block 305 drives the long side of the photovoltaic panel 8 to rotate to face the wind direction, reducing the wind load and avoiding damage to the structure due to the instantaneous impact of strong wind. Furthermore, the tilt adaptation mechanism 3 includes a connecting frame 301, and two sliders 302 are slidably connected through the inner wall of the connecting frame 301. A first fixing rod 303 is slidably connected through the interior of each slider 302. A second fixing rod 304 is fixedly connected to the opposite side of the two sliders 302. The interior of the movable block 305 is slidably connected through the outer wall of the second fixing rod 304. A fixing block 306 is fixedly connected through the top of the connecting frame 301, and a positioning post 307 is slidably connected through the interior of the fixing block 306. A limit ring 308 is slidably connected to the outer wall of the positioning post 307, and a first spring 309 is fixedly connected to the top of the limit ring 308. A tension spring 310 is fixedly connected to one end of the positioning post 307 located inside the connecting frame 301. More specifically, the installation of offshore photovoltaic (PV) platforms generally includes floating and fixed types. Floating PV platforms primarily utilize flexible connections to allow them to float on the water surface and move with the waves, enabling broad adaptability to different water depths, especially deep water areas. However, the swaying motion inherent in this flexibility during wind and waves exacerbates structural fatigue and increases maintenance costs. Currently, many environments still require fixed structures. The assembled connecting platform is rigidly connected to the seabed via pile foundations, and then the PV power generation device is installed on the connecting platform. In use, the mounting base 1 can be directly fixed to the connecting platform above the pile foundation, completing the positioning and erection of the device. The connecting platform provides a stable working environment for the PV panel 8, eliminating swaying issues and achieving better economy and reliability in suitable shallow water areas. The supporting structure then provides support for the PV panel 8 during operation. The PV panel 8 utilizes the photovoltaic effect of semiconductor materials, through… Since the photovoltaic panel 8 is installed on the sea surface, it is subject to sea winds of varying intensities during operation. When the photovoltaic panel 8 is blown by a relatively weak sea wind, it will cause the movable block 305 to slide along the outer wall of the second fixed rod 304. At the same time, the second fixed rod 304 will slide along the first fixed rod 303 via the sliders 302 at both ends. Both ends of the first fixed rod 303 are fixedly connected to the inside of the connecting frame 301. The outer wall of the limiting ring 308 is slidably connected to the inside of the fixed block 306. The end of the first spring 309 away from the limiting ring 308 is fixedly connected to the inside of the fixed block 306. The end of the tension spring 310 away from the positioning post 307 is fixedly connected to the bottom of the movable block 305. This allows the photovoltaic panel 8 to move several movable blocks 305 in a small range along the wind direction, minimizing the wind pressure on the photovoltaic panel 8 when it is first exposed to sea winds. This greatly smooths the load, prevents structural damage due to instantaneous impact, and significantly improves fatigue life. When the photovoltaic panel 8 is blown by a strong sea breeze, the movable block 305 moves to its maximum distance inside the connecting frame 301. The outer wall of the fixed block 306 slides on the inner wall of the circular groove 6. The outer wall of the positioning post 307 away from the tension spring 310 is inserted into the inner wall of the corresponding positioning hole 7. During the movement of the movable block 305, its bottom will drive one end of the tension spring 310 to move synchronously. Then the tension spring 310 will be stretched to its maximum length. The movement of the movable block 305 will then lift the positioning post 307 through the tension spring 310. The positioning post 307 will then slide upward along the inside of the fixed block 306. At the same time, the positioning post 307 will drive the limiting ring 308. Synchronous movement compresses the first spring 309, and then the bottom of the positioning post 307 slides along the inner wall of the positioning hole 7 until it disengages. At this time, the positioning post 307 no longer limits the position of the fixing block 306. Then, several fixing blocks 306 rotate along the inner wall of the circular groove 6, which in turn drives the photovoltaic panel 8 to rotate horizontally around the center of the mounting base 1. Then, the sea breeze applies pressure to the surface of the photovoltaic panel 8, causing the photovoltaic panel 8 to finally rotate to a position where its long side faces the wind, reducing the area affected by wind pressure. This ensures that the device provides a buffer for the photovoltaic panel 8 when dealing with weak winds, and automatically maximizes the protection of the main support structure and the photovoltaic panel 8 when dealing with strong winds.

[0023] Example 2, please refer to Figures 1-4 Based on Embodiment 1, in this embodiment, a rotating wind-resistant mechanism 4 is provided above the movable block 305, and the rotating wind-resistant mechanism 4 includes a sliding disk 404 provided on the top of the movable block 305. When the photovoltaic panel 8 is subjected to the wind pressure of the sea breeze, the sliding disk 404 is squeezed to move, so that the photovoltaic panel 8 changes the pitch angle around its horizontal axis to parallel the wind direction, thereby reducing the wind-receiving area and wind pressure of the photovoltaic panel 8 while enhancing stability. Furthermore, the rotating wind-resistant mechanism 4 includes a first connecting rod 401, and the first connecting rod 401 has an inner cavity 402. A second connecting rod 403 is slidably connected through the first connecting rod 401, and the bottom of the second connecting rod 403 is fixedly connected to the top of the sliding disk 404. The sliding disk 404 has several through holes 405. A second spring 406 is fixedly connected to the side of the sliding disk 404 away from the second connecting rod 403. A rotating rod 407 is rotatably connected to the end of the second connecting rod 403 away from the sliding disk 404. A fixing frame 408 is fixedly installed at the bottom of the photovoltaic panel 8, and a limit groove 409 is opened inside the fixing frame 408. More specifically, when the photovoltaic panel 8 is exposed to sea breezes during operation, the height of both sides of the photovoltaic panel 8 will change. As the photovoltaic panel 8 moves, it will cause the fixing frame 408 at its bottom to move synchronously. Then, the fixing frame 408 will tilt synchronously with the photovoltaic panel 8. During this process, the height of the fixing frame 408 will change, which will then cause the rotating rod 407 to move up and down synchronously. Simultaneously, the rotating rod 407 will slide along the inner wall of the limiting groove 409. The bottom of the first connecting rod 401 is fixedly connected to the top of the connecting frame 301, and the sliding disk 404... The outer wall is slidably connected to the inner wall of the inner cavity 402. The end of the second spring 406 away from the sliding disk 404 is fixedly connected to the inner wall of the inner cavity 402. The outer wall of the rotating rod 407 is slidably connected to the inner wall of the limiting groove 409. Then, as the rotating rod 407 moves up or down, it will drive the second connecting rod 403 to move synchronously. Then, the second connecting rod 403 will drive the sliding disk 404 to slide along the inner wall of the inner cavity 402. At the same time, the second spring 406 will be stretched or compressed. The force generated by the stretching or compression provides the force for the subsequent sliding reset of the second connecting rod 403. Because the inner cavity 402 is filled with damping oil, during the sliding process of the sliding disk 404, the damping oil on one side will pass through the interior of several through holes 405 and move to the other side of the sliding disk 404. During this process, the sliding of the second connecting rod 403 will be relatively smooth, preventing the support structure and photovoltaic panel 8 from generating violent and destructive impacts and vibrations under strong winds. This ensures the stability of the entire structure when adjusting the tilt angle. After changing the tilt angle, the photovoltaic panel 8 will be as parallel to the wind direction as possible, adjusting itself to the state of least resistance according to the wind direction, thereby avoiding strong vibrations on the leeward side of the photovoltaic panel 8 and further enhancing stability.

[0024] Example 3, please refer to Figures 1-6 Based on Embodiment 2, in this embodiment, the downward pressure reduction mechanism 5 includes a connecting frame 502 set above the mounting base 1. When the movable block 305 drives the photovoltaic panel 8 to rotate, the synchronous rotation of the connecting frame 502 will drive the photovoltaic panel 8 to move downward towards the sea surface, so as to avoid the strong wind belt above and further reduce the wind pressure. Furthermore, the downward pressure relief mechanism 5 includes a fixed column 501, a torsion spring 503 fixedly connected to the bottom of the connecting frame 502, a bidirectional inclined groove 504 opened on the outer wall of the fixed column 501, a protruding rod 505 fixedly connected inside the connecting frame 502, the inside of the connecting frame 502 being slidably connected to the outer wall of the fixed column 501, the end of the torsion spring 503 away from the connecting frame 502 being fixedly connected to the top of the mounting base 1, and the outer wall of the protruding rod 505 slidingly against the inner wall of the bidirectional inclined groove 504. More specifically, when the sea breeze blows the photovoltaic panel 8, causing several fixing blocks 306 to slide along the inner wall of the circular groove 6, several connecting frames 301 will rotate along with the fixing blocks 306. Simultaneously, the connecting frames 301 will drive the connecting frame 502 to rotate synchronously. Then, the connecting frame 502 will drive the protruding rod 505 to slide along the inner wall of the bidirectional inclined groove 504. The rotation of the connecting frame 502 will compress the torsion spring 503. After the sea breeze subsides and stabilizes, the force generated by the compression can drive the positioning post 307 to re-insert into the inner wall of the positioning hole 7, returning the photovoltaic panel 8 to its working state. Since the fixing post 501 is... Above the fixed mounting base 1, and with the bidirectional inclined groove 504 being designed at an angle, the bidirectional inclined groove 504 slides along the protruding rod 505, causing the connecting frame 502 to move down a certain distance. At the same time, the connecting frame 502 causes the connecting frame 301 to squeeze the circular groove 6, causing the circular groove 6 to slide down the same distance along the inner wall of the rotating ring 2. At this time, the overall height of the photovoltaic panel 8 will also move down with the circular groove 6, thereby shortening the distance between the photovoltaic panel 8 and the sea surface. This further reduces the height of the photovoltaic panel 8, which has already been adjusted to a streamlined posture, causing the center of gravity of the entire photovoltaic panel 8 to drop, thereby avoiding strong winds and further reducing wind pressure.

[0025] The working principle of this invention is as follows: By fixing the mounting base 1 to the connecting platform above the pile foundation, the connecting platform with the pile foundation provides a stable working environment for the photovoltaic panel 8. Then, the supporting structure can provide support for the photovoltaic panel 8 during use. The photovoltaic panel 8 is based on the photovoltaic effect of semiconductor materials and converts light energy into electrical energy. Since the installation environment is located on the sea surface, it will be affected by sea winds of different intensities during operation. When the photovoltaic panel 8 is blown by a sea wind with a relatively small force, the photovoltaic panel 8 will drive the movable block 305 to slide along the outer wall of the second fixed rod 304. At the same time, the second fixed rod 304 will slide along the first fixed rod 303 through the sliders 302 at both ends. This will cause the photovoltaic panel 8 to drive several movable blocks 305 to move in a small range along the wind direction, minimizing the wind pressure on the photovoltaic panel 8 when it is first affected by the sea wind and greatly smoothing the load. When the photovoltaic panel 8 is blown by a strong sea breeze, the movable block 305 moves to its maximum distance inside the connecting frame 301. The outer wall of the fixed block 306 slides on the inner wall of the circular groove 6. The outer wall of the positioning post 307 away from the tension spring 310 is inserted into the inner wall of the corresponding positioning hole 7. During the movement of the movable block 305, its bottom will drive one end of the tension spring 310 to move synchronously. Then the tension spring 310 will be stretched to its maximum length. The movement of the movable block 305 will then lift the positioning post 307 through the tension spring 310. The positioning post 307 will then slide upward along the inside of the fixed block 306. At the same time, the positioning post 307 will drive the limiting ring 308 to move synchronously, causing the first spring 30... 9 is compressed, and then the bottom of the positioning column 307 will slide along the inner wall of the positioning hole 7 until it is disengaged. At this time, the positioning column 307 no longer limits the position of the fixing block 306. Then, several fixing blocks 306 rotate along the inner wall of the circular groove 6, which will drive the photovoltaic panel 8 to rotate horizontally around the center of the mounting base 1. Then, the sea breeze applies pressure to the surface of the photovoltaic panel 8, so that the photovoltaic panel 8 finally rotates to the position where its long side faces the wind, reducing the area subjected to wind pressure. This ensures that the device provides a buffer for the photovoltaic panel 8 when dealing with weak winds. At the same time, when dealing with strong winds, the device automatically maximizes the protection of the main support structure and the photovoltaic panel 8, avoiding damage to the structure due to instantaneous impact and significantly improving fatigue life. When the photovoltaic panel 8 is moved by the sea breeze, causing several fixing blocks 306 to slide along the inner wall of the circular groove 6, several connecting frames 301 will rotate along with the fixing blocks 306. At the same time, the connecting frames 301 will drive the connecting frame 502 to rotate synchronously. Then, the connecting frame 502 will drive the protruding rod 505 to slide along the inner wall of the bidirectional inclined groove 504. Simultaneously, the rotation of the connecting frame 502 will compress the torsion spring 503. After the sea breeze decreases and stabilizes, the force generated by the compression can drive the positioning post 307 to be re-inserted into the inner wall of the positioning hole 7. Since the fixing post 501 is fixed above the mounting base 1... Meanwhile, the bidirectional inclined groove 504 is designed with an inclination, so when the bidirectional inclined groove 504 slides along the protruding rod 505, it will cause the connecting frame 502 to move down one end of the distance. At the same time, the connecting frame 502 will cause the connecting frame 301 to squeeze the circular groove 6, so that the circular groove 6 slides down the same distance along the inner wall of the rotating ring 2. At this time, the overall height of the photovoltaic panel 8 will also move down with the circular groove 6, thereby shortening the distance between the photovoltaic panel 8 and the sea surface. Further reducing the height of the photovoltaic panel 8, which has already been adjusted to a streamlined posture, will lower the center of gravity of the entire photovoltaic panel 8, thereby avoiding strong winds and further reducing wind pressure.
