Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic support technology, specifically relating to an adjustable tilt angle photovoltaic support auxiliary load-bearing structure. Background Technology

[0002] Solar photovoltaic (PV) mounting brackets are specialized supports designed for placing, installing, and securing solar panels in a solar photovoltaic power generation system. Common materials include aluminum alloy, carbon steel, and stainless steel. As a solar PV mounting bracket manufacturer, we primarily use aluminum alloy as the material for our brackets.

[0003] Domestic utility model patent application number 202121719948.4 discloses an adjustable pressure-resistant and windproof photovoltaic bracket, including a base plate, a connecting plate, and a bracket. The top end of the base plate is fixedly connected to the bottom end of the bracket. A lifting device is provided at the top end of the base plate, and a shock-absorbing device is fixedly connected to the top end of the bracket. Fixing devices are fixedly connected to both ends of the base plate. This utility model allows adjustment of the height of the threaded rod by rotating the first handle, thereby adjusting the tilt of the connecting plate and adjusting the angle of sunlight between the solar panel and the ground to achieve the best irradiation effect. By rotating the second handle, the fixing rod is adjusted to the bottom. After the fixing device fixes the entire device, the stability is further increased, which can reduce the wind-exposed area, reduce the damage to the solar panel in strong winds, and reduce the swaying amplitude when the connecting plate adjustment angle remains unchanged, thus reducing the damage to the solar panel caused by swaying. The aforementioned utility model reduces the wind-exposed area, thus mitigating damage to solar panels from strong winds. However, the spring components in the shock-absorbing device are prone to corrosion and weathering under long-term outdoor conditions, leading to elasticity failure. Although the angle can be adjusted to reduce the wind-exposed area, the photovoltaic panel still cannot withstand significant snow pressure during snowy weather. To ensure its actual load-bearing capacity, the bottom of the photovoltaic panel needs to be reinforced. Furthermore, to reduce the wind-exposed area, the angle of the photovoltaic panel needs to be adjusted, affecting its irradiated area and thus its power generation. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an adjustable tilt angle photovoltaic support auxiliary support structure, comprising multiple sets of photovoltaic panels, multiple sets of concrete blocks, and a support frame cast and installed on top of the concrete blocks. A positioning frame is fixedly installed on the top of the support frame, and a flipping frame is flipped and installed on the positioning frame. A set of support trusses is fixedly installed on the top of the multiple sets of flipping frames. Two sets of auxiliary supports are fixedly installed on the flipping frames, and cross support frames are connected and installed through the auxiliary supports. The top of the cross support frames is connected and installed to the other two sets of support trusses. The photovoltaic panels are fixedly installed on the three sets of support trusses through multiple sets of clamping blocks, and multiple sets of connecting plates are welded and installed at the bottom of the support trusses.

[0005] As a further preferred technical solution of this utility model; multiple sets of docking plates are welded and installed at the bottom of the load-bearing truss, and four sets of fixing frames corresponding to the positions of the docking plates are welded and installed at the top of the cross support frame, and the fixing frames are fixedly installed to the docking plates by fixing bolts. The auxiliary brackets are fixedly installed in four sets between the cross support frame and the two sets of flipping frames.

[0006] The cross support frame increases the stability of the connection between the two sets of photovoltaic panels and increases the load-bearing capacity of the frame for the photovoltaic panels. The auxiliary support frame is fixedly installed between the flip frame and the cross support frame to ensure the overall stability of the cross support frame and prevent the photovoltaic panels from collapsing due to the weak load-bearing capacity at the bottom when encountering snow pressure. At the same time, the auxiliary support frame can also resist some of the wind force.

[0007] As a further preferred technical solution of this utility model; the flipping frame includes a flipping block that cooperates with the positioning frame to flip, a flipping shaft is connected and installed between the flipping blocks through the positioning frame, an installation frame is welded and installed on the top of the flipping block, and the installation frame is connected and installed with the docking plate.

[0008] By manually rotating the flipping shaft, multiple sets of flipping blocks mounted on a set of flipping shafts are rotated, thereby flipping the photovoltaic panels on the load-bearing truss that are connected to the top of the flipping blocks, thus achieving the function of adjustable tilt angle.

[0009] As a further preferred technical solution of this utility model; an installation plate is welded and installed at the bottom of the positioning frame, a locking block is provided on the positioning frame at the bottom position of the flipping block, a top plate is welded and installed on the top of the bearing frame, an adjusting bolt is connected and installed at the bottom of the locking block through a bearing, and the adjusting bolt is threaded through the installation plate, and a through hole larger than the diameter of the adjusting bolt is opened on the top plate.

[0010] The angle of the photovoltaic panel is adjusted by the flipping shaft. After adjusting to the specified position, the adjusting bolt is rotated to limit the height of the locking block, so that the two ends of the locking block rub against the flipping block to ensure the position of the flipping block, thereby locking the tilt angle of the photovoltaic panel.

[0011] As a further preferred technical solution of this utility model, a limiting groove is provided inside the bearing truss, and multiple sets of locking holes are provided on the bearing truss.

[0012] The locking holes facilitate the locking and installation of photovoltaic panels.

[0013] As a further preferred technical solution of this utility model, the clamping block is provided with clamping grooves for clamping and positioning the two sides of the photovoltaic panel, and a positioning block is welded and installed at the bottom of the clamping block in the limiting groove. A through bolt is installed through the clamping block, and the through bolt passes through the bearing truss for fixing and locking.

[0014] The photovoltaic panel is snapped into the clamping groove on both sides. The positioning block is inserted into the limiting groove from one end of the supporting truss. After adjusting the position of the photovoltaic panel, the through bolt is tightened. The through bolt clamps and the supporting truss together to clamp and fix the photovoltaic panel, ensuring the stability of the photovoltaic panel installation. Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The cross support frame increases the stability of the connection between the two sets of photovoltaic panels, increases the load-bearing capacity of the frame for the photovoltaic panels, and the auxiliary support is fixedly installed between the flip frame and the cross support frame to ensure the overall stability of the cross support frame and prevent the photovoltaic panels from collapsing due to the weak load-bearing capacity at the bottom when encountering snow pressure. At the same time, the auxiliary support can also resist some of the wind force.

[0017] 2. When encountering wind resistance and snow pressure, the interaction forces between the load-bearing trusses can be reinforced by cross support frames. This increases the stability of the photovoltaic panels while ensuring that the angle adjusted by the flip axis remains unchanged, thus not affecting the solar-received area of ​​the photovoltaic panels.

[0023] This specific embodiment is an adjustable tilt angle photovoltaic support auxiliary load-bearing structure.

[0024] The aforementioned utility model reduces the wind-exposed area, thus mitigating damage to solar panels from strong winds. However, the spring components in the shock-absorbing device are prone to corrosion and weathering under long-term outdoor conditions, leading to elasticity failure. Although the angle can be adjusted to reduce the wind-exposed area, the photovoltaic panel still cannot withstand significant snow pressure during snowy weather. To ensure its actual load-bearing capacity, the bottom of the photovoltaic panel needs to be reinforced. Furthermore, to reduce the wind-exposed area, the angle of the photovoltaic panel needs to be adjusted, affecting its irradiated area and thus its power generation.

[0025] Its structural diagram is as follows Figures 1-4As shown, an adjustable tilt photovoltaic support auxiliary support structure includes multiple sets of photovoltaic panels 6, multiple sets of concrete blocks 1, and a support frame 2 cast and installed on top of the concrete blocks 1. A positioning frame 4 is fixedly installed on the top of the support frame 2, and a flipping frame 7 is flipped and installed on the positioning frame 4. A set of support trusses 3 is fixedly installed on the top of the multiple sets of flipping frames 7. Two sets of auxiliary supports 62 are fixedly installed on the flipping frames 7, and cross support frames 61 are connected and installed through the auxiliary supports 62. The top of the cross support frames 61 is connected to the other two sets of support trusses 3. Multiple sets of connecting plates 31 are welded and installed at the bottom of the support trusses 3. Four sets of fixing frames 63, corresponding to the positions of the connecting plates 31, are welded and installed on the top of the cross support frames 61. The fixing frames 63 are fixedly installed to the connecting plates 31 by fixing bolts. The auxiliary supports 62 are fixedly installed in four sets between the cross support frames 61 and the two sets of flipping frames 7. The cross support frame 61 increases the stability of the connection between the two sets of photovoltaic panels 6 and increases the load-bearing capacity of the support frame for the photovoltaic panels 6. The auxiliary support frame 62 is fixedly installed between the tilting frame 7 and the cross support frame 61, ensuring the overall stability of the cross support frame 61 and preventing collapse of the photovoltaic panels 6 due to weaker bottom load-bearing capacity under snow pressure. The auxiliary support frame 62 also helps resist some wind force. The tilting frame 7 includes tilting blocks 72 that cooperate with the positioning frame 4 for tilting. A tilting shaft 8 is installed between the tilting blocks 72 and the positioning frame 4. An installation frame 71 is welded to the top of the tilting blocks 72 and is connected to the docking plate 31. By manually rotating the tilting shaft 8, multiple sets of tilting blocks 72 installed on one set of tilting shafts 8 are rotated, causing the photovoltaic panels 6 on the load-bearing truss 3 connected to the top of the tilting blocks 72 to tilt, thus achieving an adjustable tilt angle. A mounting plate 41 is welded to the bottom of the positioning frame 4. A locking block 23 is installed on the positioning frame 4 at the bottom of the flipping block 72. A top plate 22 is welded to the top of the support frame 2. An adjusting bolt 21 is installed at the bottom of the locking block 23 via a bearing connection, and the adjusting bolt 21 is threaded through the mounting plate 41. A through hole larger than the diameter of the adjusting bolt 21 is opened on the top plate 22. The angle of the photovoltaic panel 6 is adjusted by the flipping shaft 8. After adjusting to the designated position, the adjusting bolt 21 is rotated to limit the height of the locking block 23, so that the two ends of the locking block 23 rub against and lock the flipping block 72, ensuring the position of the flipping block 72, thereby locking the tilt angle of the photovoltaic panel 6.

[0026] The photovoltaic panel 6 is fixedly mounted on three sets of supporting trusses 3 by multiple sets of clamping blocks 5. The supporting trusses 3 have internal limiting grooves 33 and multiple sets of locking holes 32. The clamping blocks 5 have clamping grooves 51 for engaging and positioning the two sides of the photovoltaic panel 6. Positioning blocks 53 are welded to the bottom of the clamping blocks 5 within the limiting grooves 33. Through bolts 52 are installed through the clamping blocks 5, and these through bolts 52 pass through the supporting trusses 3 for secure locking. The photovoltaic panel 6 is clamped into the clamping grooves 51 on both sides. The positioning blocks 53 are inserted into the limiting grooves 33 from one end of the supporting truss 3. After adjusting the position of the photovoltaic panel 6, the through bolts 52 are tightened. During the tightening process of the clamping blocks 5 and the supporting trusses 3, the through bolts 52 clamp and fix the photovoltaic panel 6, ensuring the stability of the photovoltaic panel 6 installation. When encountering wind resistance and snow pressure, the cross support frame 61 can reinforce the interaction force between the load-bearing trusses 3, and increase the stability of the photovoltaic panel 6 while ensuring that the angle adjusted by the flip axis 8 to the photovoltaic panel 6 remains unchanged, so as not to affect the sunlight-receiving area of ​​the photovoltaic panel 6.

[0027] The photovoltaic panel 6 is snapped into the clamping groove 51 on both sides. The positioning block 53 is placed into the limiting groove 33 from one end of the supporting truss 3. After adjusting the position of the photovoltaic panel 6, the through bolt 52 is tightened. The angle of the photovoltaic panel 6 is adjusted by the flipping shaft 8. After adjusting to the designated position, the adjusting bolt 21 is rotated to limit the height of the locking block 23, so that the two ends of the locking block 23 rub against the flipping block 72 to ensure the position of the flipping block 72, thereby locking the tilt angle of the photovoltaic panel 6.

[0028] All technical features in this embodiment can be freely combined according to actual needs.

[0029] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
