Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically a wind-resistant reinforcement device for large photovoltaic supports. Background Technology

[0002] With the booming development of the new energy industry, photovoltaic power generation, as a clean and renewable energy utilization method, has been widely used. Large-scale photovoltaic power plants usually need to install a large number of photovoltaic panels, which are fixed to the ground by photovoltaic brackets. However, in some windy areas, especially when encountering strong winds and severe weather, the photovoltaic brackets are easily impacted by strong winds, causing the brackets to sway, tilt, or even collapse. This not only damages the photovoltaic panels and affects the power generation efficiency, but may also bring safety hazards.

[0003] Currently, existing wind-resistant reinforcement measures for photovoltaic (PV) brackets are relatively simple, mostly involving increasing the number of fixed piles at the bottom of the bracket to improve stability. However, this method has limited effectiveness against strong winds. Under strong winds, PV brackets will still sway significantly, which can easily lead to fatigue damage to the bracket structure over time. In addition, some reinforcement devices are complex to install, making them inconvenient for later maintenance and adjustment, thus increasing the cost of use.

[0004] Therefore, this utility model provides a wind-resistant reinforcement device for large photovoltaic supports to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wind-resistant reinforcement device for large photovoltaic supports, comprising multiple right-angled triangular frames, each consisting of horizontal, vertical, and diagonal bars. Inclined bars are fixedly installed between the diagonal bars of the right-angled triangular frames. Pile blocks are fixedly installed at the bottom of both ends of the horizontal bars of the right-angled triangular frames. The pile blocks are fixedly installed on the ground by casting. An installation assembly is provided on the outer side of the horizontal bars of the right-angled triangular frames. A stabilizing assembly is provided at the bottom of the installation assembly. The installation assembly includes a horizontal plate that fits against the top of the horizontal bars of the right-angled triangular frames. The stabilizing assembly includes a second screw, with a rotating rod fixedly installed at the bottom of the second screw. A helical blade is fixedly installed on the outer side of the rotating rod. The second screw is screwed through the interior of the horizontal plate.

[0007] Preferably, an L-shaped plate is fixedly installed at the bottom of the horizontal plate, the horizontal bar of the right-angled triangular frame is located between the horizontal plate and the L-shaped plate, a first screw is threaded through the inside of the L-shaped plate, a clamping block is rotatably connected to the top of the first screw, a first knob is fixedly installed at the bottom of the first screw, and the clamping block is attached to the bottom of the horizontal bar of the right-angled triangular frame.

[0008] Preferably, each L-shaped plate has two first screws threaded through it, and the lead angle of the first screw thread is less than the equivalent friction angle.

[0013] This invention provides a wind-resistant reinforcement device for large photovoltaic (PV) supports. Compared with existing technologies, it has the following advantages:

[0014] 1. This wind-resistant reinforcement device for large photovoltaic supports features a second screw in the stabilizing component that is threaded through a horizontal plate. Rotating the second knob adjusts the depth of the rotating rod and helical blades underground to adapt to different geological conditions and wind resistance requirements.

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1 to 4This application provides a wind-resistant reinforcement device for large photovoltaic supports, including multiple right-angled triangular frames 1. The right-angled triangular frames 1 are divided into horizontal bars, vertical bars, and diagonal bars. These three bars are connected to each other to form a stable right-angled triangular structure. Utilizing the unique stability of triangles, they provide basic structural support for the entire reinforcement device. Inclined bars 4 are fixedly installed between the diagonal bars of the right-angled triangular frames 1. The inclined bars 4, together with the diagonal bars and other related bars of the right-angled triangular frames 1, form multiple small triangular structures, further enhancing the overall structural stability of the right-angled triangular frames 1 and making it less prone to deformation when subjected to strong wind impacts.

[0025] At the bottom of both ends of the horizontal bar of the right-angled triangular frame 1, pile foundation blocks 5 are fixedly installed. The pile foundation blocks 5 are made of high-strength concrete and are fixedly installed at a certain depth below the ground by on-site pouring. During the pouring process, it is ensured that the concrete is tightly bonded to the surrounding soil, so that the pile foundation blocks 5 form a firm connection with the ground, providing stable foundation support for the entire device and effectively dispersing the wind load borne by the photovoltaic bracket and reinforcement device.

[0026] An installation component 2 is provided on the outer side of the horizontal bar of the right-angled triangular frame 1. The installation component 2 includes a horizontal plate 21, which is made of steel and has high strength and rigidity. Its shape matches the horizontal bar of the right-angled triangular frame 1 and can fit tightly against the top of the horizontal bar of the right-angled triangular frame 1. An L-shaped plate 22 is fixedly installed at the bottom of the horizontal plate 21. The L-shaped plate 22 is also made of steel and is fixedly connected to the horizontal plate 21 by welding. The connection part is ground and rust-proofed to ensure the firmness and durability of the connection. The horizontal bar of the right-angled triangular frame 1 is located between the horizontal plate 21 and the L-shaped plate 22. A first screw 23 is screwed through the inside of the L-shaped plate 22. Two first screws 23 are screwed through the inside of each L-shaped plate 22. The two first screws 23 are evenly distributed along the length of the horizontal bar. This arrangement can make the clamping force act more evenly on the horizontal bar and avoid damage to the horizontal bar or the installation component 2 due to excessive force at a single point.

[0027] A clamping block 24 is rotatably connected to the top of the first screw 23. The clamping block 24 is made of wear-resistant material, and its top surface matches the contact surface of the bottom of the horizontal bar, allowing it to fit tightly against the bottom of the horizontal bar of the right-angled triangular frame 1. A first knob 25 is fixedly installed at the bottom of the first screw 23. The outer side of the first knob 25 is provided with anti-slip texture for easy gripping and rotation by the operator. The thread lead angle of the first screw 23 is less than the equivalent friction angle. This design gives the first screw 23 a self-locking function. When the first knob 25 is rotated to clamp the horizontal bar with the clamping block 24, the first screw 23... It will not rotate on its own due to external force, ensuring the firmness after clamping and preventing loosening between the installation component 2 and the horizontal bar. During installation, the horizontal plate 21 and the L-shaped plate 22 are placed on the horizontal bar of the right-angled triangular frame 1, so that the horizontal plate 21 is in contact with the top of the horizontal bar. Then, the two first knobs 25 are turned respectively, and the first screw 23 moves upward under the action of the thread, which drives the clamping block 24 to move upward until the clamping block 24 is tightly in contact with the bottom of the horizontal bar, firmly clamping the horizontal bar between the horizontal plate 21 and the clamping block 24, thus completing the fixation of the installation component 2 and the right-angled triangular frame 1.

[0028] The bottom of the mounting component 2 is equipped with a stabilizing component 3, which includes a second screw 31. The second screw 31 is screwed through the interior of the horizontal plate 21. Each horizontal plate 21 has two second screws 31 screwed through it. The two second screws 31 are symmetrically distributed on the horizontal plate 21, forming a reasonable force distribution with the first screw 23 in the L-shaped plate 22, thereby improving the stability of the entire device. A second knob 32 is fixedly installed on the top of the second screw 31. The second knob 32 is located above the horizontal plate 21 and has anti-slip texture on its outer side for easy rotation by the operator. A rotating rod 33 is fixedly installed on the bottom of the second screw 31. The rotating rod 33 is a steel round rod, and its length is determined according to the actual wind resistance requirements and geological conditions. A spiral blade 34 is fixedly installed on the outer side of the rotating rod 33. The spiral blade 34 is welded and fixed to the rotating rod 33. The pitch and blade angle of the spiral blade 34 are designed to cut smoothly into the soil when rotating, thereby enhancing the interlocking force between the rotating rod 33 and the soil.

[0029] The thread lead angle of the second screw 31 is less than the equivalent friction angle, giving it a good self-locking function. After the rotating rod 33 and the spiral blade 34 are adjusted to the appropriate depth, they can lock themselves in position and will not move up or down due to external forces such as wind. A fixing plate 35 is fixedly installed on the outside of the second screw 31. The fixing plate 35 is a round or square steel plate and is fixedly connected to the second screw 31 by welding. The fixing plate 35 is located above the horizontal plate 21 and has a certain gap with it to facilitate the subsequent installation of the pin 37. Insertion holes 36 are opened inside the horizontal plate 21 and on the outside of the second screw 31. The insertion holes 36 are evenly opened on the outside of the second screw 31 to form a circular distribution of holes. The number of insertion holes 36 is set according to actual needs, usually not less than 4, to meet the needs of fixing at different depths.

[0030] Pins 37 are inserted into both sides of the fixing plate 35. These pins 37 are made of high-strength alloy material, possessing high hardness and toughness. The bottom of each pin 37 is inserted into a corresponding socket 36. When installing the stabilizing component 3, the operator rotates the second knob 32. The second screw 31 rotates under the action of the thread, driving the rotating rod 33 and the spiral blade 34 downwards. During rotation, the spiral blade 34 continuously cuts into the soil, gradually penetrating deeper into the ground. This process is adjusted according to local geological conditions, such as soil hardness and looseness, and the anticipated potential impacts. To determine the maximum wind force, adjust the depth of the rotating rod 33 into the ground. When the soil is soft or the wind is strong, the depth can be increased appropriately, and vice versa. After the rotating rod 33 and the spiral blade 34 are adjusted to the appropriate depth, observe the position of the pin hole on the fixed plate 35 and the insertion hole 36 on the horizontal plate 21. Insert the two pins 37 from the left and right sides of the fixed plate 35 respectively, so that the bottom of the pins 37 is accurately inserted into the corresponding insertion hole 36, thereby firmly fixing the second screw 31 and preventing it from rotating on its own under the action of wind, further ensuring the stability of the stabilizing component 3.

[0031] Furthermore, all content not described in detail in this specification is prior art known to those skilled in the art, and all electrical components mentioned herein are powered by external power supply lines.

[0032] Working Principle: When encountering strong winds and severe weather, the strong winds impact the photovoltaic support structure. The photovoltaic support structure transfers the force to the right-angled triangular frame 1. The right-angled triangular frame 1, with its own triangular stability and the reinforcement effect of the inclined rod 4, can effectively resist part of the impact force. At the same time, the right-angled triangular frame 1 transfers part of the force to the ground through the pile block 5. The firm connection between the pile block 5 and the ground ensures the effective dispersion of this force. The rotating rod 33 and the helical blade 34 in the stabilizing component 3 penetrate deep into the ground and are closely integrated with the soil. The helical blade 34 increases the contact area and friction with the soil, providing strong pull-out resistance to resist the upward and lateral impact forces generated by the wind, thereby effectively reducing the swaying of the photovoltaic support structure and significantly improving its overall stability.

[0033] When maintenance or adjustment of the device is required, first pull out the pins 37 on both sides of the fixing plate 35 to release the fixation of the second screw 31. Then, turn the second knob 32 in the opposite direction. The second screw 31 drives the rotating rod 33 and the spiral blade 34 to rotate upward, so that the spiral blade 34 gradually detaches from the soil until the rotating rod 33 and the spiral blade 34 are completely removed from the ground. This facilitates the inspection, repair or replacement of the stabilizing component 3. If the position of the installation component 2 needs to be adjusted or it needs to be maintained, simply turn the first knob 25 in the opposite direction to move the first screw 23 and the clamping block 24 downward, releasing the clamping of the horizontal bar. Then the installation component 2 can be moved or disassembled. The operation is convenient and quick.
