Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic power generation equipment technology, specifically relating to photovoltaic brackets. Background Technology

[0002] As a key structure supporting photovoltaic modules, the strength and stability of photovoltaic brackets directly affect the safety and lifespan of the entire photovoltaic system. Traditional photovoltaic bracket steel structures typically use welding to fix the inclined beams and crossbeams together, and then attach the photovoltaic panels to the inclined beams.

[0003] Because of the large surface area of ​​photovoltaic panels after installation, the connection between the inclined beams and the crossbeams will be subjected to large tensile and shear forces under strong wind conditions. Simple welded connections are prone to cracking and eventually breakage under frequent wind pulling, which leads to a decrease in the connection strength between the inclined beams and the crossbeams in the photovoltaic support structure. Ultimately, the inclined beams and the crossbeams may detach, causing the photovoltaic panels to fall off.

[0004] Existing technologies also employ prefabricated structures to fix the inclined beams and crossbeams. For example, Chinese utility model patent CN210518167U provides a ground-mounted photovoltaic carbon steel support bracket, including: a front column and a rear column. Each of the front and rear columns has a first oblong hole at one end and at least one first through hole at the other end. The length of the front column is greater than the length of the rear column. An inclined beam is positioned between the front and rear columns, and the inclined beam has several second oblong holes that intersect the first oblong holes in a cross shape. The inclined beam is connected to the front and rear columns by bolts passing through the first and second oblong holes and then connected to nuts. A crossbeam is erected between the inclined beams and is fixedly connected to the inclined beams by purlin brackets. However, the purlin brackets are L-shaped, connected to the inclined beam on one side and the crossbeam on the other. Under extreme wind stress, they are prone to loosening and eventually separation. Utility Model Content

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a photovoltaic support structure with reinforced crossbeams. This structure solves the problem of decreased connection strength between the inclined beams and the crossbeams due to prolonged exposure to wind on the photovoltaic panels, ensuring reliable connection between the inclined beams and the crossbeams and preventing separation between them that could cause the photovoltaic panels to fall.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A photovoltaic support bracket with reinforced crossbeams includes an inclined beam and crossbeams vertically and intersectingly fixed to the inclined beam. The inclined beams are provided with a reinforcing connection assembly. The reinforcing connection assembly includes a fixing plate fixed to the inclined beam, two limiting rods arranged side by side in the longitudinal direction and fixed at their bottom ends to the fixing plate, and a top plate located above the fixing plate and connected to the top ends of the limiting rods. A positioning groove that cooperates with the crossbeams is provided between the two limiting rods. A clamping structure that cooperates with the limiting rods to press and fix the crossbeams is provided between the top plate and the limiting rods.

[0008] Preferably, the clamping structure includes a clamping plate movably connected to the limiting rod, a crossbeam located below the clamping plate, and a driving part provided on the top plate for driving the two clamping plates connected to the two limiting rods to move downward, and the two clamping plates cooperate to clamp and fix the crossbeam.

[0009] Preferably, the limiting rod is provided with a rotating seat, and the clamping plate is rotatably connected to the rotating seat through a first rotating rod and a first torsion spring, the first torsion spring having a tendency to rotate the clamping plate upward.

[0010] Preferably, the clamping structure further includes a pressure strip protruding from the bottom surface of the top plate, the pressure strip being used to drive the clamping plate.

[0011] Preferably, the clamping plate is provided with a limiting step that cooperates with the crossbeam.

[0012] Preferably, the upper part of the limiting rod is provided with a mounting cavity on the opposite side, and the rotating seat is slidably disposed in the mounting cavity.

[0013] Preferably, a limiting spring is provided between the rotating seat and the bottom surface of the mounting cavity.

[0014] Preferably, the opposite side walls of the mounting cavity are provided with vertically extending sliding grooves, and the rotating seat is provided with a slider that slides in cooperation with the sliding grooves.

[0015] Preferably, the top of the limiting rod is provided with a threaded hole, the top plate is provided with a fixing hole, the screw passes through the fixing hole and is connected to the threaded hole, so that the top plate is fixed together with the limiting rod; and / or, the fixing plate is fixed to the inclined beam by bolts.

[0016] Preferably, both the fixing plate and the top plate are rectangular structures, and four limiting rods are provided at the four corners of the rectangle.

[0017] The present invention adopts the above technical solution and has the following beneficial effects:

[0018] 1. A reinforced connection assembly is used to fix the crossbeam. This assembly includes a fixing plate fixed to the inclined beam, two longitudinally parallel limiting rods with their bottom ends fixed to the fixing plate, and a top plate located above the fixing plate and connected to the tops of the limiting rods. A positioning groove is provided between the two limiting rods to cooperate with the crossbeam. Therefore, the two limiting rods can limit the crossbeam longitudinally. Furthermore, while the positioning groove limits the crossbeam, a clamping structure between the top plate and the limiting rods clamps and fixes the crossbeam. Therefore, compared to using purlin brackets for fixing, this method increases the number of components and corresponding fixing points, fixing the crossbeam both longitudinally and vertically. From the perspective of solving the problem of decreased connection strength between the inclined and crossbeams due to long-term wind exposure of photovoltaic panels, this technical solution can more stably and reliably connect the crossbeam and inclined beam, improving the overall stability of the photovoltaic support system and preventing photovoltaic panels from falling. It has good application value in areas with frequent strong winds.

[0019] Meanwhile, the reinforced connection components can be prefabricated in the factory. The quality of the connection can be ensured by the prefabricated reinforced connection components, and the problem of reduced weld strength caused by welding operation errors of the workers can be avoided.

[0020] 2. The top plate is equipped with a driving part for driving two clamping plates connected to two limiting rods to move downward. The two clamping plates cooperate to press and fix the crossbeam. Compared with the top plate directly pressing the crossbeam, the use of movable clamping plates to press the crossbeam, under the fastening connection of the screw, the clamping plates are driven to move downward by the fastening of the top plate, so that the top plate, together with the fixing plate and the clamping plates, can connect the crossbeam and the inclined beam more stably and reliably.

[0021] 3. Since the limiting rod is equipped with a rotating seat, the clamping plate is rotatably connected to the rotating seat through the first rotating rod and the first torsion spring. The first torsion spring has a tendency to make the clamping plate rotate upward. Therefore, during installation, when the crossbeam is pressed down from the top of the two limiting rods, the crossbeam will push the two clamping plates apart downward until the bottom surface of the crossbeam is in contact with the top surface of the fixing plate, which facilitates the installation of the crossbeam. Subsequently, under the action of the first torsion spring, the clamping plate is reset upward, which also facilitates the clamping plate to press and fix the crossbeam after the top plate is fixed.

[0022] 4. The bottom surface of the top plate has a protruding pressure strip, which can be inserted downward into the mounting cavity to drive the clamping plate, without affecting the contact between the other parts of the bottom surface of the top plate and the top surface of the limit rod near the pressure strip.

[0023] 5. Since the clamping plate is provided with a limiting step that cooperates with the crossbeam, it can be matched with the shape of the crossbeam to ensure that the crossbeam is limited.

[0024] 6. Because the rotating seat slides up and down within the mounting cavity, and a limiting spring is provided between the rotating seat and the bottom surface of the mounting cavity, and vertically extending grooves are provided on the opposite side walls of the mounting cavity, and the rotating seat is provided with a slider that slides in cooperation with the grooves, the rotating seat can slide up and down, but its translation is restricted. Therefore, the clamping plate and the rotating seat can move downwards together. After the crossbeam pushes the two clamping plates downwards until the bottom surface of the crossbeam is in contact with the top surface of the fixing plate, the clamping plate and the rotating seat can return to their original position. Subsequently, when fixing the top plate, it can also be ensured that after the clamping plate is pressed into place, the limiting step on the clamping plate can cooperate with the shape of the crossbeam.

[0025] 7. Since both the fixed plate and the top plate are rectangular structures, and four limiting rods are set at the four corners of the rectangle, along with the clamps set on the limiting rods, the number of fixing points for the crossbeam is further increased, thereby ensuring the reliability of the connection between the inclined beam and the crossbeam.

[0038] To address the issue of weakened connection between the inclined beams and crossbeams due to prolonged wind exposure of photovoltaic panels, and to ensure the reliability of this connection, preventing separation and subsequent panel detachment. For example... Figures 1 to 4 As shown, this embodiment provides a photovoltaic support structure with reinforced crossbeams, including an inclined beam 2, a crossbeam 3 vertically intersecting and fixed to the inclined beam, and a column 1 supporting the inclined beam 2. The inclined beam 2 extends longitudinally and has the crossbeam 3 mounted on it. Photovoltaic modules are installed on the crossbeams. Specific installation structures can be found in existing technologies. The inclined beam 2 is equipped with a reinforcing connection component 4 to fix the crossbeam, ensuring reliable connection between the inclined beam and the crossbeam.

[0039] In this embodiment, the reinforcing connection assembly 4 includes a fixing plate 41 fixed to the inclined beam, two limiting rods 42 arranged side by side in the longitudinal direction and fixed at their bottom ends to the fixing plate, and a top plate 411 located above the fixing plate 41 and connected to the top of the limiting rods. A positioning groove that cooperates with the crossbeam 3 is provided between the two limiting rods 42. A clamping structure that cooperates with the top plate 411 and the limiting rods 42 to press and fix the crossbeam.

[0040] The above technical solution uses two limiting rods to limit the crossbeam longitudinally. Furthermore, while the positioning groove limits the crossbeam, the clamping structure between the top plate and the limiting rods presses the crossbeam firmly in place. Therefore, compared to using purlin brackets for fixing, this solution increases the number of components and corresponding fixing points, ensuring the crossbeam is fixed both longitudinally and vertically. From the perspective of addressing the problem of weakened connection between the inclined beam and the crossbeam due to long-term wind exposure of the photovoltaic panel, this technical solution can more firmly and reliably connect the crossbeam and the inclined beam, improving the overall stability of the photovoltaic support system and preventing the photovoltaic panel from falling. It has significant application value in areas with frequent strong winds.

[0041] Meanwhile, the reinforced connection components can be prefabricated in the factory. The quality of the connection can be ensured by the prefabricated reinforced connection components, and the problem of reduced weld strength caused by welding operation errors of the workers can be avoided.

[0042] In some embodiments, the clamping structure includes a clamping plate 48 movably connected to a limiting rod 42, with the crossbeam 3 located below the clamping plate 48. The top plate 411 has a driving part for driving the two clamping plates 48, which are connected to the two limiting rods, to move downwards. The two clamping plates 48 cooperate to clamp and fix the crossbeam 3. Compared to the top plate directly clamping the crossbeam, using movable clamping plates to clamp the crossbeam allows the clamping plates to move downwards under the tightening action of the screws. This, combined with the top plate, the fixing plate, and the clamping plates, enables a more stable and reliable connection between the crossbeam and the diagonal beam.

[0043] Furthermore, the limiting rod 42 is provided with a rotating seat 46, and the clamping plate 48 is hinged to the rotating seat 46. The clamping plate 48 is rotatably connected to the rotating seat 46 via a first rotating rod and a first torsion spring, the first torsion spring having a tendency to rotate the clamping plate upwards. The rotating seat 46 has a U-shaped groove, and the clamping plate is rotatably connected within the U-shaped groove. Limiting parts can be provided on both sides of the U-shaped groove, allowing the clamping plate to rotate downwards. However, after returning to its original position under the action of the first torsion spring, it is limited by the limiting parts, resulting in a roughly horizontal top surface. This facilitates its cooperation with the pressure strip on the top plate when the top plate is fixed. When the crossbeam is not installed, under the action of the first torsion spring and the limiting action between the rotating seat and the U-shaped groove, the rotating seat remains in a position where the clamping plate is roughly parallel to the fixed plate, facilitating the installation of the crossbeam. When installing the crossbeam, press the crossbeam downwards from the top of the two limiting rods. The crossbeam will push the two clamps apart until the bottom surface of the crossbeam is in contact with the top surface of the fixing plate, thus achieving the initial positioning of the crossbeam. After the crossbeam is positioned, the clamps will return to their original position under the action of the first torsion spring, which also makes it convenient for the clamps to press and fix the crossbeam after the top plate is fixed.

[0044] In this embodiment, both the inclined beam and the crossbeam can be made of square tubing. The bottom surface of the crossbeam is supported on the top surface of the fixed plate, and the longitudinal sides are positioned by limiting posts. The clamping plate rotates downward and presses against the upper side of the crossbeam.

[0045] In some embodiments, the top plate 411 is provided with a pressure strip 412 protruding from the bottom surface of the top plate for driving the clamping plate 48. The height of the pressure strip protruding from the bottom surface of the top plate ensures that the clamping plate presses and fixes the crossbeam. The clamping plate 48 is provided with a limiting step 49 that cooperates with the crossbeam 3. Specifically, the head of the clamping plate has an L-shaped structure, forming a stepped structure on the bottom surface of the head, which cooperates with the upper corner of the crossbeam.

[0046] In some embodiments, the upper part of the limiting rod has an installation cavity 44 on one side, and the rotating seat 46 is slidably disposed in the installation cavity 44. A limiting spring 410 is provided between the rotating seat 46 and the bottom surface of the installation cavity. The opposite side walls of the installation cavity 44 are provided with vertically extending grooves 45, and the rotating seat 46 is provided with a slider 47 that slides in cooperation with the groove. The pressure strip 412 can be pressed into the installation cavity and press down on the clamping plate. Due to the cooperation between the slider and the groove, the rotating seat can slide up and down a certain distance, so that the clamping plate is close to the crossbeam, and finally the limiting step cooperates with the crossbeam. Therefore, the rotating seat can slide up and down, but the translation is restricted. The clamping plate and the rotating seat can move down together. After the crossbeam pushes the two clamping plates down until the bottom surface of the crossbeam is in contact with the top surface of the fixing plate, the clamping plate and the rotating seat can be reset upward. When fixing the top plate, it can also be ensured that after the clamping plate is pressed down into place, the limiting step on the clamping plate can cooperate with the shape of the crossbeam.

[0047] Specifically, the top of the limiting rod 42 is provided with a threaded hole 43, and the top plate 411 is provided with a fixing hole. The screw 413 passes through the fixing hole and connects with the threaded hole 43, so that the top plate 411 and the limiting rod 42 are fixed together. The fixing plate 41 is fixed to the inclined beam 2 by bolts, and the corners of the fixing plate are provided with fixing holes for bolt connection. Both the fixing plate and the top plate are rectangular structures, and four limiting rods are set at the four corners of the rectangle. This further increases the fixing points for the crossbeam, thereby ensuring the reliability of the connection between the inclined beam and the crossbeam.

[0048] Using the aforementioned reinforced connection component 4, during installation, the crossbeam 3 is pressed downwards from the top of the two pairs of limiting rods 42. The crossbeam 3 will push the two pairs of clamps 48 downwards until the bottom surface of the crossbeam 3 is in contact with the top surface of the fixing plate 41. Then, all the crossbeams 3 are installed in sequence. Next, the two pressure strips 412 are aligned with the two pairs of mounting cavities 44 and pressed into the mounting cavities 44 until the bottom surface of the top plate 411 is tightly pressed against the top surface of the limiting rod 42. Then, the screw 413 is screwed into the threaded hole 43 at the top of the limiting rod 42. At this time, the top plate 411 and the limiting rod 42 are fixedly connected together. Under the pushing and limiting of the pressure strip 412, the limiting step 49 presses the top surface of the crossbeam 3 tightly. In this way, the crossbeam 3 and the inclined beam 2 are firmly connected together, improving the stability and reliability of the entire photovoltaic bracket.

[0049] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
