Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and in particular to an adjustable photovoltaic support with good seismic resistance. Background Technology

[0002] Photovoltaic (PV) mounting systems are an important component of solar photovoltaic (PV) power generation systems. They are mainly used to fix and support PV modules, ensuring they face the sun at the optimal angle to maximize solar radiation reception. Mounting systems are typically made of corrosion-resistant materials such as aluminum alloy, galvanized steel, or stainless steel, providing good structural strength and wind pressure resistance. Depending on the installation method, PV mounting systems can be divided into various types, such as ground-mounted, rooftop, and floating mounting systems, adapting to different terrains and environmental conditions. A well-designed mounting system not only ensures the long-term stable operation of PV modules but also optimizes power generation efficiency by adjusting the tilt angle, serving as a fundamental guarantee for the safe and reliable operation of PV power plants.

[0003] When photovoltaic (PV) mounting systems are put into use, the stress on them varies depending on the wind force. They cannot effectively stabilize under large wind loads, leading to potential damage to the entire system. For example, Chinese patent application CN119010728A discloses a PV mounting system with good seismic resistance. Even though this system absorbs and dissipates vibrations caused by external forces and wind through the stretching and compression of shock-absorbing and buffering springs, significantly reducing vibrations and impacts on mechanical equipment and building structures under operation or external factors, it still cannot solve the problem of damage caused by excessive wind loads during strong winds.

[0004] Therefore, how to provide an adjustable photovoltaic support system with good seismic resistance is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0027] The beneficial effects of this invention are:

[0028] 1. This invention uses a hydraulic telescopic rod to drive a rotating seat and an adjusting frame to adjust the angle of a photovoltaic panel. While the photovoltaic panel is being adjusted, a moving roller slides in a pre-set guide groove on the base. The rotating gear on the roller meshes with an external fixed toothed plate, ensuring the linearity and precision of the angle change process. At the same time, the follower frame moves synchronously in the limiting guide groove, making the photovoltaic panel angle adjustment more stable. By setting connecting arm plates on both sides of the bottom of the photovoltaic panel, structural deformation caused by uneven force can be effectively avoided.

[0029] 2. In this invention, after the photovoltaic panel is adjusted or stored in place, the electric lifting rod drives the lifting component and the elastic block to descend. The elastic block is embedded in the tooth groove of the toothed plate to achieve basic locking of the gear position. The elastic material not only provides a tight mechanical fastening, but its own deformation capability can also absorb and dissipate wind vibration energy, enabling the device to quickly switch between normal and windy conditions, and ensuring reliable pull-out and vibration resistance at any position.

[0030] 3. This invention, by setting up a function to store photovoltaic panels, allows the device to be stored and folded as needed when put into use, reducing the size of the device. The photovoltaic panels can be completely stored in the base and supported by the buffer pad, reducing the external outline and the windward cross section of the photovoltaic panels, directly storing and protecting the photovoltaic panels, which can reduce wind load, enhance the stability of the device, and reduce swaying and structural fatigue caused by wind.

[0031] 4. In this invention, when the photovoltaic panel is in a large tilt angle working state, the guide plate is adjusted to a tilted state, which can actively guide the airflow to flow smoothly over the leeward side of the photovoltaic panel, effectively destroying vortices, reducing wind-induced vibration and load, and enhancing the heat dissipation effect of the airflow on the panel surface, thereby improving the stability and efficiency of power generation. After the photovoltaic panel is stored, the guide plate tends to be vertical, converting wind force into dispersed lateral force, enhancing overall rigidity, dispersing the impact force of strong winds, protecting the photovoltaic panel under extreme weather conditions, and enabling the flowing gas to form a scouring airflow on the panel surface, achieving wind-driven self-cleaning, reducing the frequency and cost of manual cleaning, and maintaining high power generation efficiency.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0048] Example 1

[0049] refer to Figures 1-8 The present invention provides a technical solution: an adjustable photovoltaic bracket with good seismic resistance, including a photovoltaic panel 1, a storage base 2 rotatably connected to one side of the bottom of the photovoltaic panel 1, the photovoltaic panel 1 being able to rotate around the connection point within the storage base 2, and a support leg 3 fixedly connected to the bottom of the storage base 2, the device being able to be installed on the ground by setting the support leg 3, and further including:

[0050] The hydraulic telescopic rod 403 is located at the bottom of the inner side of the storage base 2. The other end of the hydraulic telescopic rod 403 is connected to the photovoltaic panel 1. When the hydraulic telescopic rod 403 is working, it can push the photovoltaic panel 1 to rotate inside the storage base 2.

[0051] A connecting arm plate 502 is disposed on the outside of the photovoltaic panel 1. A movable roller 503 is rotatably connected to the side of the connecting arm plate 502 away from the photovoltaic panel 1. A limiting disk 504 is provided on the outside of the movable roller 503. By setting the limiting disk 504, the movable roller 503 can be guided to move synchronously in cooperation with the guide groove 505 through the limiting disk 504.

[0052] The guide groove 505 is opened on both sides of the storage base 2. The limiting disk 504 on the moving roller 503 is set in the guide groove 505, and the limiting disk 504 can move in the guide groove 505. This allows the limiting disk 504 to move adaptively in the guide groove 505 when the photovoltaic panel 1 changes angle.

[0053] The toothed plate 602 is fixedly connected to the outside of the storage base 2. A rotating gear 601 is engaged at the bottom of the toothed plate 602. The middle part of the rotating gear 601 is fixedly connected to the moving roller 503. The rotating gear 601 can move at the bottom of the toothed plate 602. At the same time, the rotating gear 601 can synchronously drive the moving roller 503 to move when it moves.

[0054] The follower frame 604 is fixedly connected to the outside of the moving roller 503 and is located on the side of the follower frame 604 away from the storage base 2, and can be adjusted in position synchronously with the movement of the moving roller 503;

[0055] The locking seat 605 is located on the top of the follower frame 604 near the storage base 2. An electric lifting rod 606 is fixedly connected to the middle of the top of the locking seat 605. A lifting component 607 and an elastic block 608 are fixedly connected to the bottom of the electric lifting rod 606. When the electric lifting rod 606 is working, it can control the lifting component 607 and the elastic block 608 to insert into the tooth groove on the toothed plate 602.

[0056] The bottom of the storage base 2 is equipped with a cushioning pad, which can protect the bottom of the photovoltaic panel 1.

[0057] Working principle:

[0058] When the photovoltaic panel encounters strong winds and experiences heavy wind loads, the hydraulic telescopic rod 403 is activated. When the hydraulic telescopic rod 403 is activated, it pushes the adjusting frame 405 and connecting frame 406 to bear force, causing the photovoltaic panel 1 on the other side of the connecting frame 406 to rotate within the storage base 2. This allows for angle adjustment of the photovoltaic panel 1. When the photovoltaic panel 1 is stored within the storage base 2, the windward section of the device is reduced, and the storage of the photovoltaic panel 1 provides protection. As the photovoltaic panel 1 rotates, the rotating gear 601 on the outer connecting arm plate 502 of the photovoltaic panel 1 moves synchronously on the toothed plate 602 on the outer side of the storage base 2. By controlling the electric lifting rod 606, the lifting component 607 and the elastic locking block 608 can be inserted into the toothed groove on the outer side of the toothed plate 602, locking the position of the rotating gear 601 on the outer side of the photovoltaic panel 1, preventing the device from shaking and enhancing its stability.

[0059] Example 2

[0060] refer to Figures 1-4 Based on Embodiment 1, the present invention provides a technical solution that further includes an angle adjustment component 4, which is composed of a fixed frame 401, a rotating seat 1 402, a hydraulic telescopic rod 403, a rotating seat 2 404, an adjustment frame 405, and a connecting frame 406.

[0061] The fixed frame 401 is fixedly connected to the middle of the bottom inside the storage base 2. The rotating seat 402 is rotatably connected to the middle of the side of the fixed frame 401 away from the storage base 2. The hydraulic telescopic rod 403 is fixedly connected to one side of the rotating seat 402. The rotating seat 404 has a telescopic end. The adjusting frame 405 is fixedly connected to the telescopic end of the rotating seat 404. The connecting frame 406 is fixedly connected to the top of the adjusting frame 405.

[0062] When the hydraulic telescopic rod 403 is working, the rotating seat 402 can rotate adaptively within the fixed frame 401, while the rotating seat 404 can rotate adaptively within the adjusting frame 405.

[0063] Example 3

[0064] refer to Figures 5-8 Based on Embodiment 2, the present invention provides a technical solution that further includes a support component 5, which is composed of a rotating component 501, a connecting arm plate 502, a limiting disc 504, and a guide groove 505.

[0065] The rotating part 501 is fixedly connected to the outside of the storage base 2, the connecting arm plate 502 is rotatably connected to the middle of the outside of the rotating part 501, the limiting disc 504 is fixedly connected to the outside of the moving roller 503 and is located on the side away from the connecting arm plate 502, and the guide groove 505 is opened on the front and rear sides inside the storage base 2 and is located on the side away from the connection between the photovoltaic panel 1 and the storage base 2.

[0066] It also includes a locking assembly 6, which consists of a rotating gear 601, a toothed plate 602, a limiting guide groove 603, and a locking seat 605.

[0067] The rotating gear 601 is fixedly connected to the outside of the moving roller 503, the toothed plate 602 is fixedly connected to the outside of the storage base 2 and is located above the guide groove 505, the limiting guide groove 603 is fixedly connected to the outside of the storage base 2 and is located below the guide groove 505, and the locking seat 605 is fixedly connected to the top of the follower frame 604.

[0068] The inner side of the limiting disc 504 is disposed inside the guide groove 505, and the inner side of the limiting disc 504 is slidably connected to the guide groove 505.

[0069] The inner side of the lifting component 607 is fixedly connected to the elastic block 608. The top and bottom of the toothed plate 602 are provided with through toothed grooves, and the toothed plate 602 is connected to the rotating gear 601 through the toothed grooves.

[0070] The follower frame 604 has a guide plate fixedly connected to the bottom of the side near the storage base 2. The follower frame 604 is slidably connected to the limiting guide groove through the guide plate.

[0071] The follower frame 604 has a fixing groove in the middle, and the follower frame 604 is fixedly connected to the moving roller 503 through the fixing groove.

[0072] The number of rotating parts 501, connecting arm plate 502, moving roller 503, limiting disc 504, guide groove 505, rotating gear 601, toothed plate 602, limiting guide groove 603, follower frame 604, locking seat 605, electric lifting rod 606, lifting parts 607 and elastic locking blocks 608 are all two. The two rotating parts 501, connecting arm plate 502, moving roller 503, limiting disc 504, guide groove 505, rotating gear 601, toothed plate 602, limiting guide groove 603, follower frame 604, locking seat 605, electric lifting rod 606, lifting parts 607 and elastic locking blocks 608 are symmetrically distributed on the front and rear sides of the bottom of photovoltaic panel 1.

[0073] Working principle: When the angle of the photovoltaic panel 1 needs to be adjusted, the hydraulic telescopic rod 403 is extended, which allows the rotating seat 404, adjusting frame 405, and connecting frame 406 on the other side of the hydraulic telescopic rod 403 to be stressed, so that the photovoltaic panel 1 can rotate upward inside the storage base 2. During the rotation of the photovoltaic panel 1, the rotating component 501 on the outer side of the photovoltaic panel 1 drives the connecting arm plate 502, so that the moving roller 503 and the limiting disc 504 on the other side of the connecting arm plate 502 slide in the guide groove 505 on the outer wall of the storage base 2. This allows the rotating gear 601 on the moving roller 503 to move below the toothed plate 602 on the outer side of the storage base 2. At the same time, the follower frame 604 on the outer side of the moving roller 503 moves synchronously. 4. During movement, the photovoltaic panel 1 can slide within the limiting guide groove 603 on the outside of the storage base 2 via the guide plate, reducing the moving speed of the follower frame 604 when the photovoltaic panel 1 rotates, so that the photovoltaic panel 1 can be smoothly adjusted in angle. After the angle of the photovoltaic panel 1 is adjusted, the electric lifting rod 606 on the locking seat 605 at the top of the follower frame 604 is controlled to work, so that the electric lifting rod 606 can control the lifting component 607 and the elastic block 608 to insert into the tooth groove on the toothed plate 602, so that the lifting component 607 and the elastic block 608 can fill the tooth groove and lock the position of the rotating gear 601. At the same time, since the elastic block 608 is made of elastic material, it can absorb the vibration generated by wind load to a certain extent and reduce the impact of wind load.

[0074] In windy weather, to prevent damage to the device, the hydraulic telescopic rod 403 is retracted, allowing the photovoltaic panel 1 to rotate within the storage base 2 and be stored on the buffer pad at the bottom of the storage base 2. While the photovoltaic panel 1 rotates within the storage base 2, the connecting arm plate 502 on the outer side of the photovoltaic panel 1 rotates synchronously within the rotating component 501. This allows the rotating gear 601 on the moving roller 503 on the other side of the connecting arm plate 502 to move at the bottom of the toothed plate 602. The electric lifting rod 606 is then activated, enabling the lifting component 607 and the elastic locking block 608 to lock the position of the rotating gear 601. This strengthens the connection between the photovoltaic panel 1 and the storage base 2, improves the device's pull-out resistance, and reduces the overall windward cross-section of the device, lowering the probability of wind load damage during windy weather.

[0075] Example 4

[0076] refer to Figures 9-13Based on Embodiment 3, the present invention provides a technical solution that further includes a flow guiding component 7, which is composed of a fixed extrusion block 701, a protective groove plate 702, a fixed slide groove 703, a rotating limiting roller 704, a sliding plate 705, a flow guiding plate 706, a first drive housing 707, a second drive housing 708, a first spring 709, a first piston plate 710, an extrusion rod 711, a connecting pipe 712, a second spring 713, a second piston plate 714, and a connecting rod 715.

A protective groove plate 702 is fixedly connected to the top of the photovoltaic panel 1. A fixed slide groove 703 is fixedly connected to the bottom of the protective groove plate 702. A rotating limiting roller 704 is rotatably connected to the bottom of the protective groove plate 702 and located on the side away from the storage base 2. A sliding plate 705 is slidably connected to the bottom of the fixed slide groove 703. A guide plate 706 is hinged to the top of the sliding plate 705. Multiple guide plates 706 are evenly spaced on the top of the sliding plate 705. A drive housing 707 is fixedly connected to... The drive housing 708 is fixedly connected to the outside of the photovoltaic panel 1, located at the bottom of the protective groove plate 702 and near the connection between the photovoltaic panel 1 and the storage base 2. A spring 709 is fixedly connected to the middle of the top of the drive housing 708. A piston plate 710 is fixedly connected to the bottom of the spring 709. A pressing rod 711 is fixedly connected to the bottom of the piston plate 710. The bottom end of the pressing rod 711 passes through the middle of the bottom of the drive housing 708 and extends below the drive housing 708. The pressing rod 711 is slidably connected to the middle of the bottom of the drive housing 708. A connecting pipe 712 is fixedly connected to the top of the drive housing 708.

A circular groove is opened in the middle part of the drive housing 707 away from the drive housing 708 to accommodate the movement of the connecting rod 715. The connecting rod 715 can move within the circular groove. Damping oil is provided inside the drive housing 708 at the top of the piston plate 710. When the piston plate 710 rises, the damping oil can be squeezed into the drive housing 707 through the connecting pipe 712, which increases the pressure at the spring 713 inside the drive housing 707 and stretches the spring 713. This allows the spring 713 to push the piston plate 714 and the connecting rod 715 to move. The end of the connecting rod 715 away from the piston plate 714 is fixedly connected to the sliding plate 705. When the connecting rod 715 moves, it can synchronously drive the sliding plate 705 to move.

[0078] Working Principle: To cope with different weather conditions, the angle of the photovoltaic panel 1 needs to be adjusted. In light winds, the tilt angle of the photovoltaic panel 1 increases during rotation. This allows the pressing rod 711 at the bottom of the drive housing 708 on the outer side of the photovoltaic panel 1 to contact the fixed pressing block 701. As the rotation angle of the photovoltaic panel 1 increases, the pressing force of the pressing rod 711 on the fixed pressing block 701 gradually increases. When the pressing rod 711 is pressed by the photovoltaic panel 1, it rises within the drive housing 708. Simultaneously, the rising pressing rod 711 drives the piston plate 710 to rise within the drive housing 708. At the same time, the spring 709 at the top of the piston plate 710 is compressed, causing the interior of the drive housing 708 to be positioned above the piston plate 710. The side space is reduced, and the damping oil at the top of the piston plate 710 enters the drive housing 707 through the connecting pipe 712, increasing the pressure at the spring 713. Simultaneously, the spring 713 is stretched, and the piston plate 714 moves within the drive housing 707. This causes the connecting rod 715 to move synchronously away from the drive housing 707. As the connecting rod 715 moves, it drives the sliding plate 705 to slide at the bottom of the protective groove plate 702. As the rotation angle of the photovoltaic panel 1 increases, the pressure exerted by the photovoltaic panel 1 on the pressing rod 711 gradually increases, increasing the stroke by which the connecting rod 715 pushes the sliding plate 705 to move at the bottom of the protective groove plate 702. Since the guide plate 706 is hinged above the sliding plate 705, and the guide plate 706 is connected to the drive housing 707 by a rotating... The rotating limiting roller 704 is used for limiting the movement of the sliding plate 705. Therefore, when the sliding plate 705 moves, the guide plate 706 can adaptively and synchronously rotate inside the rotating limiting roller 704, changing the state of the guide plate 706. This allows the guide plate 706 to be tilted at the top of the photovoltaic panel 1. In light winds, it can guide the airflow passing through the front and rear sides of the photovoltaic panel 1, directing it to flow uniformly towards the lower surface of the photovoltaic panel 1. This effectively guides the airflow to pass smoothly over the panel surface. When the airflow passes through the right side of the photovoltaic panel 1 and flows to the left, the airflow is dispersed to the front and rear sides of the photovoltaic panel 1 by the guide plate 706, causing multiple airflows to converge behind the panel. Since their flow directions and speeds are different, the airflows will interfere with each other, preventing small vortices from effectively merging and growing into a powerful concentrated vortex. The flow breaks down large, concentrated vortices into multiple weak and irregular small turbulents, reducing wind load and enhancing heat dissipation on the surface of the photovoltaic panel 1. When the wind is strong, the photovoltaic panel 1 is rotated into the storage base 2 for storage. At this time, the extrusion rod 711 separates from the fixed extrusion block 701, and the fixed extrusion block 701 can no longer provide effective extrusion force to the extrusion rod 711. This causes the damping oil in the drive housing 1 707 to flow back into the drive housing 2 708, causing the connecting rod 715 to move back into the drive housing 1 707. The connecting rod 715 pulls the sliding plate 705 to move, and gradually makes the guide plate 706 on the top of the photovoltaic panel 1 tend to be vertical. After the photovoltaic panel 1 is stored, the guide plate 706 is vertically set on the top of the photovoltaic panel 1.The vertically positioned deflector 706 reduces the windward surface area, thus guiding the passing wind. Simultaneously, the guided wind washes over the top surface of the photovoltaic panel 1, cleaning dust and dirt accumulated on its surface. Furthermore, the multiple deflectors 706 connected by sliding plates 705 enhance the overall rigidity of the front and rear sides of the photovoltaic panel 1, effectively dispersing wind force and reducing localized peak wind pressure during strong wind impacts.
