Description

Technical Field

[0001] The present invention belongs to the technical field of flexible photovoltaic brackets, and in particular relates to a flexible photovoltaic bracket suitable for complex terrains. Background Art

[0002] Flexible photovoltaic bracket is a photovoltaic bracket designed based on the tension structure system. It has the characteristics of large span, high clearance and long column distance. It is fixed at both ends and uses cables as supporting members to form a large-span photovoltaic module support structure.

[0003] Existing flexible photovoltaic brackets use a steel cable structure as the supporting and mounting structure of the photovoltaic panel. However, under conditions of thermal expansion and contraction, the steel cable structure will frequently experience changes in tension due to its thermal expansion and contraction. Especially in strong wind environments, due to the lack of an effective connection structure and tension self-adjustment function between the steel cables, the swing of the steel cable structure will be aggravated under the action of wind, which can easily cause the photovoltaic panel to become seriously tilted and twisted. This tilt and twisting will cause the lighting angle of the photovoltaic panel to change, and shadows may appear in some areas, thereby greatly reducing the efficiency of photovoltaic power generation.

[0004] Combining the above-mentioned issues, it is found that it is difficult to avoid the above-mentioned problems when the existing devices on the market are in use. Therefore, we propose a flexible photovoltaic bracket suitable for complex terrain, which can self-adjust the tension of the steel cable structure under temperature changes during use, limit the displacement and deformation of the steel cable, and significantly reduce the tilt and distortion of the photovoltaic panels caused by wind. Summary of the invention

The advantage of the present invention is that the tension of the cable body can be accurately controlled by setting an anchoring structure to adapt to temperature changes, avoid sagging of the cable body due to tension changes or aggravate the swing of the photovoltaic panel in a strong wind environment. By setting a wind-resistant connection structure, the wind-resistant stability of the flexible photovoltaic bracket can be enhanced, the inclination and distortion of the photovoltaic panel can be reduced, the lighting and light reception can be ensured to be stable, the power generation efficiency can be improved, and the maintenance cost and safety risks can be reduced.

[0007] By adopting the above technical solution, the cable tension can be accurately controlled by setting an anchoring structure to adapt to temperature changes, avoid sagging of the cable due to tension changes or aggravate the swing of the photovoltaic panels in strong wind environments.

[0008] The present invention is further configured as follows: the adjustment component includes a screw rod, the screw rod passes through the interior of the fixed plate, and a connecting disk is bolted to the top of the screw rod, a first spring is arranged between the connecting disk and the connecting plate, both sides of the top of the connecting disk and the bottom of the connecting plate are bolted to fixing tubes, and a fixing rod is arranged between the opposite sides of the two fixing tubes.

[0009] By adopting the above technical solution, an adjustment component is set up, which can accurately control the tension of the cable body and adapt to the tension changes caused by factors such as thermal expansion and contraction. The screw adjusts the height of the connecting plate, and the first spring buffers and automatically adjusts the tension to keep the cable body tension within an appropriate range, avoiding affecting the stability of the bracket and the operation of the photovoltaic module.

[0010] The present invention is further configured as follows: a plurality of guide posts are bolted between opposite sides of the upper support plate and the lower support plate, and a synchronous plate is sleeved on the surface of the guide post, and the synchronous plate is connected to the connecting plate and the fixing plate at one side thereof.

[0011] By adopting the above technical solution, guide columns and synchronization plates are set. The guide columns and synchronization plates ensure that the various parts of the anchoring structure move synchronously under tension adjustment and external force. The guide columns provide precise sliding guides for the synchronization plates. The synchronization plates connect the connecting plates and the fixed plates to ensure a stable connection between the pulley block and the cable body. The anchoring structure works together as a whole to avoid damage caused by local uneven force and improve overall reliability and stability.

[0012] The present invention is further configured as follows: the pulley block includes a first fixed frame and a second fixed frame, the first fixed frame is bolted to the front side of the reinforcing beam, a fixed pulley is rotatably connected inside the first fixed frame, the second fixed frame is arranged at the front side of the first fixed frame and is connected to the cable body, a movable pulley is rotatably connected inside the second fixed frame, a connecting cable is wound around the surface of the fixed pulley, one end of the connecting cable passes around the movable pulley and is connected to the first fixed frame, and the other end of the connecting cable passes through the upper support plate and is connected to the connecting plate.

[0013] By adopting the above technical solution, a pulley block is set up, and the tension of the cable body acts on the movable pulley, which is transmitted to the connecting cable after changing the force direction through the fixed pulley. The connecting cable transmits the force to the connecting plate. When the cable body is stretched or displaced due to thermal expansion or contraction or wind force, the connecting cable can slide accordingly in the pulley block and adjust its own length to keep the force transmission stable and effective. The fixed pulley and the movable pulley are combined to change the force direction and save effort. The connecting cable connects the various components, adapts to the deformation of the cable body, evenly disperses the tension of the cable body, improves the bracket system's ability to withstand the tension of the cable body, and ensures stability and reliability.

[0014] The present invention is further configured as follows: an opening is provided on the rear side of the counterweight block, and elastic sheets are provided on both sides of the inner wall of the opening, the elastic sheet is in contact with the side close to the hollow moving column, a nut is threadedly connected to the surface of the hollow moving column, and the bottom of the nut is in close contact with the top counterweight block.

[0015] By adopting the above technical solution, elastic sheets and nuts are set, and the counterweight block opening and the elastic sheet ensure stable installation and prevent shaking and falling off. The nut and the counterweight block cooperate to facilitate the adjustment of the number of counterweights and flexibly control the tension of the cable body.

[0016] The present invention is further configured as follows: the wind-resistant connection structure includes a first connecting sleeve, the first connecting sleeve is sleeved on the surface of the middle cable body, both sides of the first connecting sleeve are bolted with connecting seats, the surfaces of the two cable bodies on both sides are sleeved with three second connecting sleeves, both sides of the connecting seat are bolted with cross bars, and the side of the cross bar close to the middle second connecting sleeve is connected to it, and diagonal braces are provided on the front and rear sides of both sides inside the connecting seat, and the diagonal braces are connected to the two second connecting sleeves on the front and rear sides.

[0017] By adopting the above technical solution, by setting up a wind-resistant connection structure, under the action of wind, the cross bar limits the lateral displacement of the cable body, and the diagonal support rod provides support force from the diagonal direction. The first connecting sleeve serves as the central connection point, and the connecting seat connects the cross bar, the diagonal support rod and the cable body. When the wind blows from one side, the cross bar bears the lateral force, and the diagonal support rod shares part of the diagonal force, so that the cable body remains relatively stable, avoiding the cable body from swinging sharply due to wind force and causing the photovoltaic panel to tilt and twist, effectively limiting the displacement and deformation of the cable body under the action of wind, reducing the tilt and twisting of the photovoltaic panel, ensuring the stability of the lighting angle and the light-receiving area, improving the efficiency of photovoltaic power generation, and reducing the maintenance cost and safety risk of wind-induced structural damage.

[0018] The present invention is further configured as follows: the cross bar includes two connecting rods, and the connecting rod is connected to the connecting seat and the second connecting sleeve in the middle on one side thereof, and a movable rod is arranged between the opposite sides of the two connecting rods. A limiting rod is arranged inside the movable rod, and the limiting rod is connected to the connecting rod on the side thereof close to the inner wall thereof, and a second spring is sleeved on the surface of the limiting rod, and the second spring is respectively connected to the movable rod and the connecting rod on the side thereof close to the inner wall thereof, and the space between the movable rod and the connecting rod is filled with oil.

[0019] By adopting the above technical solution, a cross bar is set. When wind acts on the cross bar, the cross bar is subjected to force to cause the movable rod to move in the connecting rod, the limit rod limits the moving range of the movable rod, the second spring is compressed, and the oil flows between the movable rod and the connecting rod to generate a damping force. These work together to absorb and disperse the impact energy of the wind. For example, when strong wind causes force on one side of the cross bar, the second spring is compressed to buffer part of the impact force, and the damping force of the oil slows down the moving speed of the movable rod, so that the overall force on the cross bar is more uniform and stable, reducing the impact on the cable body and the photovoltaic panel.

[0020] The present invention is further configured as follows: the support structure includes a support rod, a stud is arranged inside the support rod, and a fixing plate is welded to the bottom of the stud, and the bottom of the support rod is rotatably connected to an internal threaded barrel, and the internal threaded barrel is threadedly connected to the stud.

[0021] By adopting the above technical solution, by setting support rods, internal threaded tubes and studs, the height of the support rods can be adjusted through the cooperation of the studs and the internal threaded tube to adapt to the height differences of different terrains. There is no need for large-scale earthwork projects, the ecological environment is protected, and the construction cost and period are reduced.

[0022] The present invention is further configured as follows: a mounting plate is bolted to the bottom of the fixing plate, and an annularly arranged pre-buried anchor bolts penetrate the interior of the mounting plate, and connecting rings are welded between the surfaces of the pre-buried anchor bolts.

[0023] By adopting the above technical solution, the supporting structure is firmly connected to the ground through pre-buried anchor bolts and connecting rings, providing a stable foundation, preventing the bracket from being displaced due to external force or long-term use, ensuring the long-term stable operation of the bracket system, and reducing safety hazards and maintenance costs caused by loose foundation.

[0024] The present invention is further configured as follows: the diagonal support rod is configured as a telescopic structure, and the two ends of the diagonal support rod are rotatably connected to the connecting seat and the second connecting sleeves at the front and rear sides respectively.

[0025] By adopting the above technical solution, the diagonal support rod is retractable and rotatably connected at both ends, so that the angle and length can be flexibly adjusted under different wind directions and intensities, better adapting to wind changes, optimizing the supporting force of the cable body, enhancing wind resistance, and improving the stability of the support system under complex wind conditions.

[0026] In summary, the present invention has the following beneficial effects: By setting up the anchoring structure, the cable tension can be accurately controlled to adapt to temperature changes, avoid the cable sagging caused by tension changes or the aggravated swing of the photovoltaic panel in strong wind conditions; By setting up a wind-resistant connection structure, the wind-resistant stability of the flexible photovoltaic bracket can be enhanced, the tilt and distortion of the photovoltaic panels can be reduced, the lighting and light reception can be ensured to be stable, the power generation efficiency can be improved, and the maintenance costs and safety risks can be reduced.

[0031] like Figure 3As shown, the adjustment component 38 includes a screw 381, which passes through the interior of the fixing plate 37, and a connecting plate 382 is bolted to the top of the screw 381, a first spring 383 is arranged between the connecting plate 382 and the connecting plate 310, and fixing cylinders 384 are bolted to both sides of the top of the connecting plate 382 and the bottom of the connecting plate 310, and a fixing rod 385 is arranged between the opposite sides of the two fixing cylinders 384. By setting the adjustment component 38, the adjustment component 38 can accurately control the tension of the cable body 4 and adapt to the tension changes caused by factors such as thermal expansion and contraction.

[0032] like Figure 1 As shown, a plurality of guide columns 7 are bolted between the opposite sides of the upper support plate 31 and the lower support plate 32, and a synchronous plate 8 is sleeved on the surface of the guide column 7. The synchronous plate 8 is connected to the connecting plate 310 and the fixed plate 37 on one side thereof. By setting the guide columns 7 and the synchronous plates 8, the guide columns 7 and the synchronous plates 8 ensure that the various parts of the anchoring structure 3 move synchronously under tension adjustment and external force. The guide columns 7 provide precise sliding guides for the synchronous plates 8. The synchronous plates 8 connect the connecting plate 310 and the fixed plate 37, so that the pulley block 39 is stably connected to the cable body 4. The anchoring structure 3 works as a whole to avoid damage caused by local uneven force, thereby improving overall reliability and stability.

The connecting cable 395 transmits the force to the connecting plate 310. When the cable body 4 is stretched or displaced due to thermal expansion or contraction or wind force, the connecting cable 395 can slide accordingly in the pulley block 39 to adjust its own length to keep the force transmission stable and effective. The fixed pulley 393 and the movable pulley 394 are combined to change the force direction and save effort. The connecting cable 395 connects the various components, adapts to the deformation of the cable body 4, evenly disperses the tension of the cable body 4, improves the bracket system's ability to withstand the tension of the cable body 4, and ensures stability and reliability.

[0034] like Figure 5As shown, an opening is provided on the rear side of the counterweight block 36, and elastic sheets 9 are provided on both sides of the inner wall of the opening. The elastic sheet 9 is in contact with the side close to the hollow movable column 34. A nut is threadedly connected to the surface of the hollow movable column 34, and the bottom of the nut is in close contact with the top counterweight block 36.

[0037] A brief description of the use process: Calculate the number of counterweights 36 required according to the tension of the cable body 4, and stack the counterweights 36 on the carrier plate 35. When placing the counterweights 36, ensure that the rear opening of the counterweights 36 is aligned with the hollow moving column 34 so that the elastic sheet 9 can clamp the hollow moving column 34 to prevent the counterweights 36 from shaking or falling off.

Then, adjust the height of the connecting plate 382 by the screw rod 381 to fine-tune the tension of the cable body 4. When the temperature rises, the cable body 4 stretches and its tension decreases. At this time, the cable body 4 The pulling force on the pulley group 39 is also reduced. Under the action of the movable pulley 394 and the fixed pulley 393, the connecting cable 395 will transmit this change to the connecting plate 310, and the pulling force on the connecting plate 310 is reduced. By utilizing the reset of the first spring 383 and the gravity of the counterweight block 36, the tension of the cable body 4 is adjusted so that the tension of the cable body 4 is compensated to a certain extent. On the contrary, when the temperature drops, the cable body 4 shrinks and the pulling force increases, the connecting cable 395 will pull the connecting plate 310 upward, and the gravity of the counterweight block 36 interacts with the pulling force of the cable body 4 to achieve a balance of force, thereby preventing the cable body 4 from being damaged due to excessive tension or affecting the stability of the photovoltaic bracket.

[0038] Embodiment 2: refer to Figure 7-8 , comprising two supporting structures 1, a reinforcing beam 2 is arranged on the top between the opposite sides of the two supporting structures 1, an anchoring structure 3 is arranged on the opposite side of the two supporting structures 1, a cable body 4 is arranged at the other end of the anchoring structure 3, a wind-resistant connecting structure 5 is sleeved on the surface of the cable body 4, a cable 6 is arranged on the surface of the reinforcing beam 2, and the cables 6 on both sides are symmetrically arranged. By arranging the wind-resistant connecting structure 5, the wind-resistant stability of the flexible photovoltaic bracket can be enhanced, the inclination and distortion of the photovoltaic panel can be reduced, the lighting and light receiving stability can be ensured, the power generation efficiency can be improved, and the maintenance cost and safety risks can be reduced.

[0039] like Figure 7As shown, the wind-resistant connection structure 5 includes a first connection sleeve 51, the first connection sleeve 51 is sleeved on the surface of the middle cable body 4, both sides of the first connection sleeve 51 are bolted with a connection seat 52, the surfaces of the two cable bodies 4 on both sides are sleeved with three second connection sleeves 53, both sides of the connection seat 52 are bolted with a cross bar 54, and the side of the cross bar 54 close to the middle second connection sleeve 53 is connected to it, the front and rear sides of both sides of the connection seat 52 are provided with diagonal braces 55, and the side of the diagonal braces 55 close to the front and rear second connection sleeves 53 is connected to them, by setting the wind-resistant connection structure 5, under the action of wind, the cross bar 54 limits The cable body 4 is prevented from lateral displacement, and the diagonal support rod 55 provides support force from the diagonal direction. The first connecting sleeve 51 serves as the central connecting point, and the connecting seat 52 connects the cross bar 54 with the diagonal support rod 55 and the cable body 4. When the wind blows from one side, the cross bar 54 bears the lateral force, and the diagonal support rod 55 shares part of the diagonal force, so that the cable body 4 remains relatively stable, avoiding the cable body 4 from swinging sharply due to wind force and causing the photovoltaic panel to tilt and twist, effectively limiting the displacement and deformation of the cable body 4 under the action of wind, reducing the tilt and twisting of the photovoltaic panel, ensuring the stability of the lighting angle and the light-receiving area, improving the efficiency of photovoltaic power generation, and reducing the maintenance cost and safety risk of structural damage caused by wind.

[0040] like Figure 8 As shown, the cross bar 54 includes two connecting rods 541, and the connecting rod 541 is connected to the connecting seat 52 and the second connecting sleeve 53 in the middle at one side thereof, and a movable rod 542 is arranged between the opposite sides of the two connecting rods 541, and a limiting rod 543 is arranged for the internal movement of the movable rod 542, and the limiting rod 543 is connected to the connecting rod 541 at one side thereof close to the inner wall thereof, and a second spring 544 is sleeved on the surface of the limiting rod 543, and the second spring 544 is connected to the movable rod 542 and the connecting rod 541 at one side thereof close to the inner wall thereof, and a space is filled between the movable rod 542 and the connecting rod 541. It is filled with oil and a cross bar 54 is set. When wind acts on the cross bar 54, the cross bar 54 is stressed to make the movable rod 542 move in the connecting rod 541, and the limit rod 543 limits the moving range of the movable rod 542. The second spring 544 is compressed, and the oil flows between the movable rod 542 and the connecting rod 541 to generate a damping force. These work together to absorb and disperse the impact energy of the wind. For example, when strong wind causes force on one side of the cross bar 54, the second spring 544 compresses and buffers part of the impact force, and the oil damping force slows down the moving speed of the movable rod 542, so that the overall force on the cross bar 54 is more uniform and stable, reducing the impact on the cable body 4 and the photovoltaic panel.

Under the action of wind force, the cross bar 54 limits the lateral displacement of the cable body 4, and the diagonal support rod 55 provides support force from the diagonal direction. The first connecting sleeve 51 is used as the central connection point, and the connecting seat 52 connects the cross bar 54 and the diagonal support rod 55 to the cable body 4. When the wind blows from one side, the cross bar 54 bears the lateral force, and the diagonal support rod 55 is connected to the cable body 4. 55 shares part of the oblique force, so that the cable body 4 remains relatively stable, and avoids the cable body 4 from swinging sharply due to wind force, thereby causing the photovoltaic panel to tilt and twist, effectively limiting the displacement and deformation of the cable body 4 under the action of wind force, and reducing the tilt and twist of the photovoltaic panel. When the wind acts on the cross bar 54, the cross bar 54 is forced to make the movable rod 542 move in the connecting rod 541, the limit rod 543 limits the moving range of the movable rod 542, the second spring 544 is compressed, and the oil flows between the movable rod 542 and the connecting rod 541 to generate a damping force. These work together to absorb and disperse the wind impact energy.
