Description

Technical Field

[0001] This application relates to the field of photovoltaic support technology, and in particular to a photovoltaic support with a more stable structure. Background Technology

[0002] Solar photovoltaic (PV) brackets are special brackets designed for placing, installing, and fixing solar panels in a solar PV power generation system. They are generally made of aluminum alloy, carbon steel, and stainless steel, and often require a large ground-mounted pile bracket.

[0003] An existing patent (publication number: CN223067052U) discloses a photovoltaic bracket, including two supporting columns on both sides. The top of the supporting columns is hinged to a rotatable support rod. The lower front and rear ends of the support rod are respectively hinged to the supporting columns via front and rear adjusters. The front and rear adjusters on both sides are securely connected by adjusting rods. Rotating the adjusting rods drives the front and rear adjusters to open and close, thereby adjusting the angle of the support rod. This utility model has a simple structure and is easy to operate. It only requires rotating the two adjusting rods simultaneously to drive the corresponding pair of front and rear adjusters to extend and retract, thereby adjusting the tilt angle of the support rod for mounting the photovoltaic panels. Moreover, the lateral adjusting rods provide stable support for the support rod, preventing it from shaking and deforming under stress.

[0004] However, in actual use, photovoltaic panels are affected by external factors such as wind, which affects the stability of the support structure. In order to further reduce the impact of external factors such as wind, it is necessary to provide a photovoltaic support structure with a more stable structure. Utility Model Content

[0005] The purpose of this application is to provide a more stable photovoltaic support structure, which adopts a triangular distributed anchoring method, increasing the resistance to the support being pulled out of the ground by stresses such as wind, and solving the problems mentioned in the background art.

[0006] The photovoltaic support structure with a more stable structure provided in this application adopts the following technical solution: A photovoltaic support structure with a more stable structure includes multiple column assemblies and multiple crossbeams. The column assembly includes telescopic columns and connectors installed at the telescopic ends of the telescopic columns. An anchoring assembly is provided at the bottom end of the column assembly. The anchoring assembly includes a base plate fixedly connected to the bottom end of the telescopic column. Multiple connecting columns are fixedly connected to the bottom surface of the base plate. A contact plate is provided below the base plate. The bottom ends of the multiple connecting columns are fixedly connected to the upper surface of the contact plate.

[0007] Three rotatable arc-shaped anchor claws are hinged at the edge of the contact plate. A lead screw is rotatably sleeved on the inner bottom wall of the base plate. A sleeve block is threadedly connected to the outer surface of the lead screw. Three connecting plates are hinged to the outer surface of the sleeve block. The bottom ends of the three connecting plates are respectively hinged to the top ends of the three arc-shaped anchor claws.

[0008] By adopting the above technical solution, and utilizing the triangular distribution of the arc-shaped anchor claws, in conjunction with the screw drive block to drive the connecting plate to adjust the unfolding angle of the arc-shaped anchor claws, the arc-shaped anchor claws can penetrate deep into the soil and form multi-point pull-out support. This effectively increases the pull-out resistance of the support under wind force, prevents the anchoring components from loosening from the soil, and thus improves the overall stability of the support, solving the problem of support displacement caused by wind. At the same time, by adjusting the unfolding angle of the arc-shaped anchor claws, the anchoring requirements under different terrains can be met, making it more practical.

[0009] Preferably, the multiple column assemblies are fixedly connected by multiple crossbeams.

[0010] By adopting the above technical solution, the dispersed column components are connected into an overall frame structure using crossbeams. This allows the wind load on a single column component to be transferred to adjacent column components through the crossbeams, thus distributing the load and preventing individual column components from deforming due to excessive local stress. At the same time, it enhances the overall resistance to lateral displacement and reduces the lateral impact of wind on the device.

[0011] Preferably, the inner sides of the plurality of crossbeams are provided with X-shaped reinforcement members, and the plurality of crossbeams are fixedly connected to each other by the X-shaped reinforcement members.

[0012] By adopting the above technical solution, the X-type reinforcement can form a cross support structure between the beams. By utilizing the principle of triangular stability, the connection stiffness between the beams is improved. When wind force acts on the beams and generates lateral or longitudinal tension, the X-type reinforcement can directly bear part of the load and decompose it, avoiding relative displacement or bending deformation between the beams, further enhancing the horizontal wind resistance stability, and making up for the shortcomings of traditional supports in terms of torsion and shear resistance.

[0013] Preferably, a solar photovoltaic panel is provided above the plurality of column assemblies, and the output ends of the plurality of connectors are fixedly connected to the outer surface of the solar photovoltaic panel.

[0014] By adopting the above technical solution, the connectors, as the connection medium between the column assembly and the solar photovoltaic panel, can evenly transfer the wind load on the solar photovoltaic panel to the column assembly below, avoiding damage to the connection point between the solar photovoltaic panel and the support due to concentrated force. At the same time, the multi-point fixing method of multiple connectors can prevent the solar photovoltaic panel from warping or swaying under the action of wind, ensuring the stability of the connection between the solar photovoltaic panel and the support, and reducing fatigue damage to the solar photovoltaic panel and the connection structure caused by wind.

[0015] Preferably, a miniature frame is fixedly connected to the upper surface of the contact plate, a fixed sleeve is fixedly connected to the top of the miniature frame, and the bottom end of the lead screw is rotatably sleeved on the inner wall of the fixed sleeve.

[0016] By adopting the above technical solution, the miniature frame and the fixed sleeve cooperate to form the bottom support structure of the lead screw, which can limit the radial displacement of the lead screw during rotation and ensure that the lead screw always moves stably along the axial direction. This ensures the accuracy of the sleeve block when driving the connecting plate to adjust the arc-shaped anchor claw. At the same time, the support structure can share the vertical pressure borne by the lead screw, prevent the lead screw from failing due to bending under force, ensure the stable realization of the adjustment function of the anchoring component, and indirectly improve the wind-resistant fixing effect.

[0017] Preferably, a knob is fixedly connected to the bottom end of the lead screw, and the outer surface of the knob is provided with uniformly distributed anti-slip texture.

[0018] By adopting the above technical solution, the knob provides a convenient operating component for adjusting the lead screw, while the anti-slip texture increases the friction between the operator's hand and the knob, preventing slippage during adjustment. This ensures that the operator can stably rotate the lead screw to adjust the unfolding angle of the arc-shaped anchor claw, guaranteeing that the anchoring component can be accurately installed according to the soil conditions on site. This, in turn, ensures the pull-out support effect of the arc-shaped anchor claw and improves the reliability of the bracket installation and fixation.

[0019] Preferably, the inner wall of the contact plate has evenly distributed positioning holes.

[0020] By adopting the above technical solution, the positioning holes can be used in conjunction with ground fixing components to further enhance the connection strength between the contact plate and the ground, and prevent the contact plate from sliding horizontally under the action of wind. At the same time, the uniform distribution of the positioning holes can make the contact plate more evenly stressed, reduce the deformation of the contact plate caused by local stress concentration, ensure the overall stability of the anchoring component, provide a stable installation foundation for the arc-shaped anchor claw, and indirectly improve the wind resistance of the device.

[0021] Preferably, the connecting column is a rubber damping column.

[0022] By adopting the above technical solution, the connecting column made of rubber damping column has good elastic buffering performance. When the wind causes the support to vibrate, the connecting column can absorb some of the vibration energy, weaken the intensity of the vibration transmitted to the base plate and the contact plate, and reduce the fatigue damage of the vibration to the connection point of the anchoring component. At the same time, the rubber damping column can adapt to a certain degree of displacement deformation, avoid rigid fracture of the connecting column due to wind impact, ensure the stability of the connection between the column component and the anchoring component, and improve the overall wind vibration resistance.

[0023] In summary, this application includes at least one of the following beneficial technical effects: This more stable photovoltaic support structure utilizes a triangular distribution of arc-shaped anchor claws in the anchoring components, combined with a lead screw drive block to adjust the unfolding angle of the connecting plate. Compared to the single fixing method of existing technologies, it can form multi-point pull-out support, significantly increasing the pull-out resistance under wind force and preventing the anchoring components from loosening. Furthermore, the crossbeams connect the dispersed column components into an overall frame, achieving load distribution and preventing localized deformation of individual column components. The X-shaped reinforcements between the crossbeams utilize the triangular stability principle to enhance connection stiffness, compensating for the insufficient torsional and shear resistance of traditional supports. At the same time, the connectors evenly transmit the wind load of the solar photovoltaic panels, preventing damage to the connection points. The micro-frame and fixing sleeve ensure stable movement of the lead screw, the knob facilitates precise adjustment, the positioning holes enhance the connection between the contact plate and the ground, and the connecting columns absorb vibration energy. Overall, stability is improved from multiple dimensions such as fixing, connection, and buffering, effectively solving the problems of support displacement and deformation caused by wind interference in existing technologies.

[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0027] Example 1: A more stable photovoltaic support structure, referring to... Figure 1 , Figure 4 and Figure 5The system includes multiple column assemblies 1 and multiple crossbeams 2. Each column assembly 1 includes a telescopic column 101 and a connector 102 installed at the telescopic end of the telescopic column 101. The telescopic column 101 is an existing product, consisting of an outer sleeve and a sliding inner tube. The telescopic column 101 itself changes length and has a built-in elastic pin, which limits the adjusted height. An anchoring assembly 4 is located at the bottom of each column assembly 1. The anchoring assembly 4 includes a base plate 401 fixedly connected to the bottom of the telescopic column 101. Multiple connecting columns 402 are fixedly connected to the bottom surface of the base plate 401. A contact plate 403 is located below the base plate 401. The bottom ends of the multiple connecting columns 402 are fixedly connected to the upper surface of the contact plate 403. Three rotatable arc-shaped anchor claws 404 are hinged to the edge of the contact plate 403. The inner bottom wall of the base plate 401... A lead screw 407 is rotatably mounted, and a sleeve block 408 is threadedly connected to the outer surface of the lead screw 407. Three connecting plates 409 are hinged to the outer surface of the sleeve block 408. The bottom ends of the three connecting plates 409 are respectively hinged to the top ends of three arc-shaped anchor claws 404. The inner wall of the contact plate 403 is provided with evenly distributed positioning holes 410. The positioning holes 410 can be used with ground fixing components to further enhance the connection strength between the contact plate 403 and the ground and prevent the contact plate 403 from sliding horizontally under the action of wind. At the same time, the even distribution of the positioning holes 410 can make the contact plate 403 more evenly stressed, reduce the deformation of the contact plate 403 caused by local stress concentration, ensure the overall stability of the anchoring assembly 4, provide a stable installation foundation for the arc-shaped anchor claws 404, and indirectly improve the wind resistance of the device. The connecting column 402 is a rubber damping column.

[0028] Reference Figure 1 , Figure 4 and Figure 5A miniature frame 405 is fixedly connected to the upper surface of the contact plate 403. A fixed sleeve 406 is fixedly connected to the top of the miniature frame 405. The bottom end of the lead screw 407 is rotatably sleeved on the inner wall of the fixed sleeve 406. The miniature frame 405 and the fixed sleeve 406 cooperate to form the bottom support structure of the lead screw 407, which can limit the radial displacement of the lead screw 407 during rotation and ensure that the lead screw 407 always moves stably along the axial direction. This ensures the accuracy of the sleeve block 408 when driving the connecting plate 409 to adjust the arc-shaped anchor claw 404. At the same time, this support structure can share the vertical pressure borne by the lead screw 407, preventing the lead screw 407 from failing due to bending under force, ensuring the stable realization of the adjustment function of the anchoring component 4, and indirectly improving the wind-resistant fixing effect. A knob 411 is fixedly connected to the bottom end of the lead screw 407. The outer surface of the knob 411 is provided with evenly distributed anti-slip texture. The knob 411 provides a convenient operating component for adjusting the lead screw 407. The anti-slip texture increases the friction between the operator's hand and the knob 411, preventing slippage during adjustment and ensuring that the operator can stably rotate the screw 407 to adjust the unfolding angle of the arc-shaped anchor claw 404. This ensures that the anchoring component 4 can be accurately installed according to the soil conditions on site, thereby ensuring the pull-out support effect of the arc-shaped anchor claw 404 and improving the reliability of the bracket installation. The connecting column 402, made of rubber damping column material, has good elastic buffering performance. When the wind causes the bracket to vibrate, the connecting column 402 can absorb some of the vibration energy, weakening the intensity of the vibration transmitted to the base plate 401 and the contact plate 403, and reducing the fatigue damage of the vibration to the connection point of the anchoring component 4. At the same time, the rubber damping column can adapt to a certain degree of displacement deformation, preventing the connecting column 402 from rigidly breaking due to wind impact, ensuring the stability of the connection between the column component 1 and the anchoring component 4, and improving the overall wind vibration resistance.

[0029] Example 2: A more stable photovoltaic support structure, referring to... Figure 1 , Figure 2 and Figure 3Based on the same concept as Embodiment 1 above, this embodiment proposes a fixed connection between multiple column components 1 via multiple crossbeams 2. The crossbeams 2 connect the dispersed column components 1 into an overall frame structure, allowing the wind load on a single column component 1 to be transferred to adjacent column components 1 via the crossbeams 2, thus distributing the load and preventing deformation of a single column component 1 due to excessive local stress. This also enhances the overall lateral displacement resistance and reduces the lateral impact of wind on the device. X-shaped reinforcement members 3 are provided on the inner sides of the multiple crossbeams 2, and the multiple crossbeams 2 are fixedly connected via X-shaped reinforcement members 3. The X-shaped reinforcement members 3 form a cross-support structure between the crossbeams 2, utilizing the principle of triangular stability to improve the connection stiffness between the crossbeams 2. When wind force acts on the crossbeams 2, generating lateral or longitudinal tensile force, the X-shaped reinforcement members 3 can directly bear part of the load and... Its decomposition avoids relative displacement or bending deformation between the crossbeams 2, further enhancing the horizontal wind resistance stability and making up for the shortcomings of traditional supports in terms of torsional and shear resistance. A solar photovoltaic panel 5 is installed above multiple column components 1, and the output ends of multiple connectors 102 are fixedly connected to the outer surface of the solar photovoltaic panel 5. The connectors 102 serve as the connection medium between the column components 1 and the solar photovoltaic panel 5, and can evenly transfer the wind load on the solar photovoltaic panel 5 to the column components 1 below, avoiding damage to the connection point between the solar photovoltaic panel 5 and the support due to concentrated force. At the same time, the multi-point fixing method of multiple connectors 102 can prevent the edges of the solar photovoltaic panel 5 from lifting or swaying under the action of wind, ensuring the stability of the connection between the solar photovoltaic panel 5 and the support, and reducing the fatigue damage of wind to the solar photovoltaic panel 5 and the connection structure.

[0030] The implementation principle of this application embodiment is as follows: First, the foundation is fixed by the anchoring component 4. The operator rotates the knob 411 to drive the lead screw 407 to rotate. Because the bottom end of the lead screw 407 is limited and supported by the fixed sleeve 406 at the top of the miniature frame 405, it can ensure that the lead screw 407 moves stably along the axial direction. When the lead screw 407 rotates, it drives the sleeve block 408 connected by the thread on the outer surface to move up and down. The sleeve block 408 drives the three arc-shaped anchor claws 404 on the edge of the contact plate 403 to unfold or retract through the hinged connecting plate 409, so that the arc-shaped anchor claws 404 It can penetrate deep into the soil layer to form a triangular distributed pull-out support according to soil conditions. At the same time, the positioning holes 410 on the inner wall of the contact plate 403, in conjunction with the ground fixing components, further enhance the connection stability between the contact plate 403 and the ground, preventing the anchoring component 4 from shifting. Then, the bottom end of the telescopic column 101 of the column assembly 1 is fixed to the base plate 401 of the anchoring component 4. The sliding inner tube in the telescopic column 101 can drive the connecting component 102 to adjust the height. The limiting structure inside the telescopic column 101 can ensure the stability after the height is adjusted. Once the desired height is reached, multiple column assemblies 1 are connected into a single frame using crossbeams 2. X-shaped reinforcement members 3 are installed inside the crossbeams 2 to enhance the connection rigidity between them using the principle of triangular stability, preventing relative displacement of the crossbeams 2 under external forces. Next, the solar photovoltaic panels 5 are fixed above the multiple column assemblies 1 using connectors 102 at the telescopic ends of the telescopic columns 101 in the column assembly 1. When external factors such as wind act on the solar photovoltaic panels 5, the load is first evenly transferred to the telescopic columns 101 through the connectors 102, and then... The crossbeam 2 distributes the load borne by a single column assembly 1 to adjacent column assemblies 1, avoiding localized stress concentration. Meanwhile, the X-shaped reinforcement 3 further decomposes the lateral or longitudinal tensile forces on the crossbeam 2. The connecting column 402 between the base plate 401 and the contact plate 403 in the anchoring assembly 4 absorbs the vibration energy generated by the wind, weakening the impact of vibration on the connection point between the anchoring assembly 4 and the column assembly 1. The arc-shaped anchor claw 404 provides continuous pull-out resistance, preventing the whole assembly from loosening or shifting due to wind, ultimately achieving stable support under wind interference.
