Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and specifically to an installation device for a photovoltaic bracket. Background Technology

[0002] Photovoltaic (PV) mounting systems are a crucial component of solar photovoltaic (PV) power generation systems, used to support and install PV modules. Installation must be carried out on-site at the PV field. The conventional method for installing PV mounting systems is the "single-component sequential installation method," which involves installing the support components, diagonal beams, purlins, and PV panels sequentially from bottom to top. For example... Figure 1 As shown, the supporting components of the photovoltaic bracket mainly include a front column 33, a rear column 34, a crossbeam 35, a front diagonal brace 36, and a rear diagonal brace 37. The front column 33 and the rear column 34 are installed on the top of the pile foundation 40 using two clamps and the crossbeam 35. Then, the diagonal beam 32 is installed obliquely on the top of the front column 33 and the rear column 34 by bolt connection. The purlin 31 is installed on the diagonal beam 32, so that the purlin 31 and the diagonal beam 32 form a rectangular frame. Finally, the photovoltaic panel 30 is installed on the purlin 31.

[0003] During photovoltaic (PV) bracket installation, significant deviations exist between the inclined beams and the purlins above them. This causes the purlin mounting surfaces to fail to meet the flatness requirements for PV panel installation. Consequently, workers must repeatedly adjust the support components below the inclined beams and the position of the inclined beams themselves. However, in practice, scaffolding is often erected on land or boats on water, and high-altitude work platforms are used to repeatedly adjust the height of the uprights, the angle of the diagonal braces, and the position of the inclined beams. Due to the lack of specialized leveling equipment, workers rely on manual measurement and experience, resulting in lengthy adjustments each time. Consequently, the current PV bracket installation process is time-consuming and costly. Summary of the Invention

[0004] To address the issue of repeatedly adjusting the height of the columns, the angle of the diagonal braces, and the position of the inclined beams in the support components during photovoltaic module installation on a high-altitude work platform, which is time-consuming due to the lack of specialized leveling tools and the reliance on manual measurement and experience by workers, resulting in long construction periods and high costs for existing photovoltaic support systems, this utility model proposes an installation device for photovoltaic support systems. This device changes the conventional photovoltaic support system installation method by first placing the purlins, then installing the photovoltaic modules, inclined beams, and support components in sequence, and finally fixing the entire system to the top of the pile foundation. This eliminates the manual adjustment process during high-altitude operations, improves assembly efficiency, and reduces construction costs.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A photovoltaic bracket installation device includes a base, an installation platform disposed above the base, and a lifting mechanism disposed on the base for driving the installation platform to rise and fall. The installation platform has several notches with openings facing the side where the pile foundation is located. An inclined platform is disposed between two adjacent notches. Several rows of placement slots are provided on the front of each inclined platform. Several rows of blocks for fixing the edges of photovoltaic panels are also provided on each inclined platform.

[0007] Furthermore, the placement groove is a U-shaped groove, with its first sidewall perpendicular to the bottom and its second sidewall forming an obtuse angle with the bottom. This structural arrangement prevents interference between the purlin and the placement groove during the separation of the inclined platform from the purlin.

[0008] Furthermore, the lifting mechanism is configured as two sets, located on the left and right sides of the base respectively. The lifting mechanism includes upper and lower scissor arm assemblies, and the ends of the upper and lower scissor arm assemblies are rotatably connected by pins. The lower scissor arm assembly is connected to a hydraulic cylinder.

[0009] Furthermore, each layer of the scissor arm assembly includes a first link and a second link arranged in an X-shape. The intersection of the first link and the second link is rotatably connected by a pivot. A support shaft connects the two first links in the lower layer of the scissor arm assembly. The piston rod of the first cylinder is hinged to the support shaft, and the cylinder body of the first cylinder is hinged to the base. When the first cylinder extends, the mounting platform rises accordingly; when the first cylinder retracts, the mounting platform descends accordingly.

[0010] Furthermore, in the upper scissor arm assembly, one end of each of the two connecting rods is hinged to the mounting platform, and one end of each of the two connecting rods is equipped with an upper roller. In the lower scissor arm assembly, one end of each of the two connecting rods is hinged to the base, and one end of each of the two connecting rods is equipped with a lower roller. The bottom surface of the mounting platform is provided with a pair of upper rails, and the top ends of each of the two connecting rods in the upper scissor arm assembly are slidably connected to the pair of upper rails via upper rollers. The top surface of the base is provided with a pair of lower rails, and the bottom ends of each of the two connecting rods in the lower scissor arm assembly are slidably connected to the pair of lower rails via lower rollers. Both ends of the upper and lower rails are equipped with baffles. The upper rollers roll horizontally along their corresponding upper rails, and the lower rollers roll horizontally along their corresponding lower rails.

[0011] Furthermore, one end of the tilting platform is hinged to the mounting platform, and an adjustment mechanism is provided between the tilting platform and the mounting platform. The adjustment mechanism includes two opposing vertical plates, with a lead screw rotatably connected between the two plates and at least one guide rod fixedly connected thereto. The guide rod and the lead screw are arranged parallel to each other. A slider is also provided between the two vertical plates, with a threaded hole and a through hole on the slider. The lead screw passes through the threaded hole of the slider and engages with it in a threaded manner. The guide rod passes through the through hole of the slider. A connecting rod is hinged above the slider, and the other end of the connecting rod is hinged to the tilting platform. One end of the lead screw passes through one of the vertical plates and is connected to a handwheel. By setting up the adjustment mechanism, the angle between the mounting platform and the tilting platform can be finely adjusted.

[0012] Furthermore, the stops are arranged in two rows, one above the other, and are ⊥-shaped blocks with a chamfer on one side of their bottom surface. This prevents the stops from scraping against the lower row of photovoltaic panels during the separation of the tilting platform from the crossbeam.

[0013] The beneficial effects of this utility model through the above technical solution are as follows:

[0014] This invention uses an inclined platform to place four purlins on the inclined platform before laying the photovoltaic panels, ensuring that the purlin mounting surface meets the flatness requirements for photovoltaic panel installation. This avoids the need for repeated adjustments to the column height, brace angle, and beam position in the support components on an aerial work platform.

[0015] During installation, four purlins are placed sequentially in the four rows of grooves, followed by the installation of photovoltaic panels. The photovoltaic panels are placed between two adjacent blocks and fixed to the purlins using connectors. Then, the inclined beams and support components are installed. The device is then transported to the designated location and the base is fixed. The height of the installation platform is higher than the height of the pile foundation. When the hydraulic cylinder shortens, the installation platform descends until the crossbeam of the support component contacts the top of the pile foundation. The support component is then installed on top of the pile foundation using two clamps and the crossbeam, completing the construction of the photovoltaic bracket. Through the above setup, this invention changes the conventional photovoltaic bracket installation method to first placing the purlins, then installing the photovoltaic modules, inclined beams, and support components in sequence, and finally fixing the entire assembly to the top of the pile foundation. This eliminates the need for manual adjustment during high-altitude operations, improves assembly efficiency, and reduces construction costs. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0031] like Figures 1-12 As shown, this embodiment provides a photovoltaic bracket installation device, including a base 1, an installation platform 2 disposed above the base 1, and a lifting mechanism disposed on the base 1 for driving the installation platform 2 to rise and fall. The installation platform 2 has several notches 3 with openings facing the side where the pile foundation 40 is located. An inclined platform 4 is disposed between two adjacent notches 3. Several rows of placement slots 5 are opened on the front of each inclined platform 4. Several rows of blocks 6 for fixing the edges of the photovoltaic panel 30 are also disposed on each inclined platform 4.

[0032] In this embodiment, the photovoltaic modules adopt a 2×n array, that is, the photovoltaic panels 30 are arranged in two rows, one above the other, with several distributed in each row along the horizontal direction. Each photovoltaic panel 30 is fixed to the purlin 31 by connectors. Specifically, four purlins 31 are installed between the inclined beams 32 of two adjacent pile foundations 40 by bolt connection, and four rows of placement slots 5 are opened on the inclined platform 4. When laying the photovoltaic panels 30, the photovoltaic panels 30 are placed between two adjacent blocks 6.

[0033] Please refer to this again. Figure 5 and Figure 12 The placement groove 5 is a U-shaped groove, with its first sidewall perpendicular to the bottom and its second sidewall forming an obtuse angle with the bottom. This structure prevents interference between the purlin 31 and the placement groove 5 during the separation of the inclined platform 4 from the purlin 31.

[0034] In this utility model, the lifting mechanism is configured as two sets and located on the left and right sides of the base 1 respectively. The lifting mechanism includes upper and lower scissor arm assemblies. The ends of the upper and lower scissor arm assemblies are rotatably connected by pins 7. The lower scissor arm assembly is connected to a hydraulic cylinder 8.

[0035] Specifically, each layer of the scissor arm assembly includes a first connecting rod 9 and a second connecting rod 10 arranged in an X-shape. The intersection of the first connecting rod 9 and the second connecting rod 10 is rotatably connected by a pivot 11. A support shaft 12 connects the two first connecting rods 9 in the lower layer of the scissor arm assembly. The piston rod of the first hydraulic cylinder 8 is hinged to the support shaft 12, and the cylinder body of the first hydraulic cylinder 8 is hinged to the base 1. When the first hydraulic cylinder 8 extends, it lifts the support shaft 12, thereby supporting the first connecting rod 9 and the second connecting rod 10, and the mounting platform 2 also rises accordingly; conversely, when the first hydraulic cylinder 8 retracts, the mounting platform 2 descends accordingly.

[0036] Please refer to this again. Figure 7 and Figure 8In the upper scissor arm assembly, one end of each of the two connecting rods 9 is hinged to the mounting platform 2. One end of each of the two connecting rods 10 in the upper scissor arm assembly is equipped with an upper roller 13. One end of each of the two connecting rods 10 in the lower scissor arm assembly is hinged to the base. One end of each of the two connecting rods 9 in the lower scissor arm assembly is equipped with a lower roller 14. A pair of upper rails 15 are provided on the bottom surface of the mounting platform 2. The top ends of the two connecting rods 10 in the upper scissor arm assembly are slidably connected to the pair of upper rails 15 via the upper rollers 13. A pair of lower rails 16 are provided on the top surface of the base. The bottom ends of the two connecting rods 9 in the lower scissor arm assembly are slidably connected to the pair of lower rails 16 via the lower rollers 14. Baffles 17 are provided at both ends of the upper rails 15 and lower rails 16. The upper rollers 13 roll horizontally along their corresponding upper rails 15, and the lower rollers 14 roll horizontally along their corresponding lower rails 16.

[0037] Please refer to this again. Figure 6 and Figure 9 One end of the inclined platform 4 is hinged to the mounting platform 2. An adjustment mechanism is also provided between the inclined platform 4 and the mounting platform 2. The adjustment mechanism includes two opposing upright plates 18. A lead screw 19 is rotatably connected between the two upright plates 18 and at least one guide rod 20 is fixedly connected to them. The guide rod 20 and the lead screw 19 are arranged in parallel. A slider 21 is also provided between the two upright plates 18. The slider 21 has a threaded hole and a through hole. The lead screw 19 passes through the threaded hole of the slider 21 and is threadedly engaged with the threaded hole of the slider 21. The guide rod 20 passes through the through hole of the slider 21. A support rod 22 is hinged above the slider 21. The other end of the support rod 22 is hinged to the inclined platform 4. One end of the lead screw 19 passes through one of the upright plates 18 and is connected to a handwheel 23.

[0038] The applicant considered that the photovoltaic panel 30 often requires fine-tuning of its angle at the construction site, especially considering factors such as geographical location, seasonal changes, and environmental shading. For example, terrain shading, such as mountains or buildings, may cause localized shadows. When installing the photovoltaic bracket at the construction site, the tilt angle of the photovoltaic panel 30 needs to be fine-tuned to avoid shading areas. To this end, this utility model also includes an adjustment mechanism. By rotating the handwheel 23 clockwise or counterclockwise, the lead screw 19 also rotates, and the slider 21 moves back and forth along the guide rod 20, driving the support rod 22 to move. This causes the tilting platform 4 to swing to the left or right by a certain angle, achieving the purpose of fine-tuning the angle between the mounting platform 2 and the tilting platform 4, that is, achieving fine-tuning of the tilt angle of the photovoltaic panel 30.

[0039] It is worth mentioning that the top of the mounting platform 2 is also engraved with scale lines, and a pointer corresponding to the scale lines is fixedly installed on one side of the slider 21. By setting the cooperation between the slider 21, the pointer and the scale lines, the pointer points to the scale line at the scale distance, so that the sliding distance of the slider 21 remains consistent, and the tilt angle of the photovoltaic panels 30 on the three tilting platforms 4 is adjusted synchronously.

[0040] In this invention, the stop blocks 6 are arranged in two rows, one above the other. Each stop block 6 is a ⊥-shaped block, and one side of the bottom surface of the stop block 6 is chamfered. This prevents the stop blocks 6 from scraping against the lower row of photovoltaic panels 30 during the separation of the tilting platform 4 from the crossbeam.

[0041] The working principle of this utility model is as follows:

[0042] During installation, four purlins 31 are placed in the four rows of grooves in sequence, and then the photovoltaic panels 30 are laid. The photovoltaic panels 30 are placed between two adjacent blocks 6 and fixed to the purlins 31 with connectors. Then, the inclined beams 32 and the support components are installed. The installation sequence of each component in the support components is as follows: front column 33, rear column 34, crossbeam 35, front diagonal brace 36 and rear diagonal brace 37.

[0043] After the device is transported to the designated location, the base 1 is fixed. At this time, the height of the mounting platform 2 is higher than the height of the pile foundation 40. Then, the hydraulic cylinder 8 shortens, and the mounting platform 2 descends until the crossbeam 35 in the support assembly contacts the top of the pile foundation 40. The front column 33 and the rear column 34 are installed on the top of the pile foundation 40 by using two clamps and the crossbeam 35, thus completing the construction of the photovoltaic bracket.

[0044] During land construction, the base 1 is fixed to the ground and then assisted by a hydraulic outrigger. During water operations, when the base 1 is fixed to the construction vessel, it is then firmly fixed to the pipe pile by relying on the hull. The purpose of both methods is to effectively suppress the risk of tilting during the construction of the device and to meet the requirements of photovoltaic support construction on land and water.

[0045] In summary, this utility model changes the conventional photovoltaic bracket installation method by first placing the purlin 31, then installing the photovoltaic module, inclined beam 32, and support component in sequence, and finally fixing the whole assembly to the top of the pile foundation 40. This eliminates the manual adjustment process during high-altitude operations, improves assembly efficiency, and reduces construction costs.

[0046] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
