Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and specifically to a photovoltaic support construction device. Background Technology

[0002] Solar photovoltaic (PV) power generation systems are a new type of power generation system that utilizes the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. The solar cell array is supported by a photovoltaic support structure, such as... Figure 1 As shown, the photovoltaic support system mainly consists of pipe piles 50, upper clamps 48, lower clamps 49, support components, and purlins 41. The support components include inclined beams 42, front columns 43, rear columns 44, crossbeams 45, front diagonal braces 46, and rear diagonal braces 47. The front columns 43 and rear columns 44 are installed on top of the pipe piles 50 using two clamps and crossbeams 45. Then, the inclined beams 42 are installed obliquely on top of the front columns 43 and rear columns 44 using bolts. Purlins 41... 1. Installed on the inclined beam 42, forming a rectangular frame between the purlin 41 and the inclined beam 42. Specifically, four purlins 41 are bolted between the inclined beams 42 of two adjacent pipe piles 50. After assembly, the inclined beam 42, the front column 43, and the front diagonal brace 46 together form a triangular structure, and the inclined beam 42, the rear diagonal brace 47, and the rear column 44 together form another triangular structure. The triangles increase stability. Figure 2 As shown, the photovoltaic modules are installed on the purlins 41. The photovoltaic modules adopt a 2×n array, that is, the photovoltaic panels 40 are arranged in two rows, one above the other, with several distributed in each row along the horizontal direction. Each photovoltaic panel 40 needs to be fixed to the purlins 41 by connectors.

[0003] During construction, the conventional installation method involves erecting scaffolding to connect the support components to the pipe piles, then installing the purlins arranged at an angle, and finally installing the photovoltaic panels one by one on the four purlins. The applicant discovered that when assembling the purlins onto the inclined beams of the support components, there was a significant misalignment between the inclined beams and the purlins above them, preventing the photovoltaic panels from being installed. Therefore, during installation, workers need to repeatedly adjust the height of the columns, the angle of the diagonal braces, and the position of the inclined beams in the support components. However, in actual operation, installation is all at height, making precise adjustments difficult and resulting in a cumbersome installation process with high labor costs. This leads to long construction periods and high construction costs for existing photovoltaic systems. Therefore, developing a photovoltaic system construction device that improves mechanization and reduces installation losses is crucial for reducing photovoltaic system installation costs and improving installation quality and efficiency. Summary of the Invention

[0004] To address the problem that existing photovoltaic (PV) support system construction requires workers to repeatedly adjust the positions of support components and inclined beams, which is often done at heights and makes precise adjustments difficult, resulting in a cumbersome installation process, high labor costs, long construction periods, and high construction costs, this invention proposes a PV support system construction device. This device changes the traditional method of installing PV panels on four purlins arranged at an angle. Instead, the PV panels are assembled on a platform, followed by the sequential installation of the purlins and support components, and finally, the assembly is joined to the pipe piles. This simplifies construction and installation, quickly avoids construction errors, effectively improves the installation efficiency and quality of PV support systems, and significantly reduces installation costs.

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

[0006] A photovoltaic support construction device includes a base, a movable component is provided on the upper surface of the base, a lifting component is provided above the movable component, and a tilting component is provided above the lifting component; the tilting component includes a bracket provided on the lifting component, a tilting plate hinged to the bracket, and two hydraulic cylinders hinged to the bracket, the piston rod of the hydraulic cylinders being hinged to one side of the tilting plate, and a platform being provided on the other side of the tilting plate.

[0007] The platform has two rows of limiting members on its front side for fixing the edges of the photovoltaic panels. Each row of limiting members includes several horizontally spaced first blocks and two second blocks located on the outermost sides of the first blocks. The first blocks are inverted T-shaped, and the second blocks are L-shaped. The bottom surfaces of the first and second blocks in the upper row are both beveled. The platform also has four rows of clamping plates on its front side, with at least two clamping plates in each row, spaced horizontally. One end of each clamping plate is bent upward to form a hook. The platform also has a sliding groove for the clamping plates to pass through. The other end of each clamping plate passes through the sliding groove and is connected to a drive assembly, which drives the clamping plate to slide within the sliding groove. The moving assembly can drive the lifting assembly to move horizontally, and the lifting assembly can drive the tilting assembly to move vertically.

[0008] Furthermore, the moving component includes a motor fixedly mounted on the upper surface of the base. Two upright plates are fixedly mounted on the upper surface of the base, and a lead screw is rotatably mounted between the two upright plates. The output end of the motor is fixedly connected to one end of the lead screw via a coupling. A threaded seat is provided on the lead screw, and the lead screw passes through the threaded seat and is threadedly connected to the threaded seat. A sliding seat is fixedly mounted above the threaded seat. When the motor rotates, it drives the lead screw to rotate, and the sliding seat moves forward or backward with the forward and reverse rotation of the lead screw.

[0009] Furthermore, two symmetrical guide rails are fixedly mounted on the upper surface of the base, and sliders are slidably mounted on the guide rails. The sliders are fixedly connected to the sliding seats. The sliders slide in cooperation with the guide rails, and move between the two upright plates.

[0010] Furthermore, the lifting assembly includes a second hydraulic cylinder mounted on the upper surface of the sliding seat and two guide rods. Each guide rod is equipped with a guide unit, and a crossbeam is mounted on the top of the two guide units. The piston rod of the second hydraulic cylinder is fixedly connected to the crossbeam. The second hydraulic cylinder drives the crossbeam, thereby driving the tilting assembly to lift and lower.

[0011] Furthermore, the guide unit includes rollers disposed on the left and right sides of the guide rod, and support plates are disposed on both the front and rear sides of the guide rod, with the two support plates connected by side plates; the rollers are rotatably mounted on the support plates via pins, and the rollers are located at the upper and lower ends of the support plates, simultaneously contacting the guide rod; two crossbeams are disposed on one side of the support plate, and the bracket is fixedly connected to one of the crossbeams, while a reinforcing rib is disposed between the other crossbeam and the bracket. By setting up the guide unit, the rollers on the support base maintain close contact with their corresponding guide rods, making the lifting operation more stable and reliable.

[0012] Furthermore, the drive assembly is located on the back of the platform. The drive assembly includes a hydraulic cylinder three hinged to the platform. Outer sleeves are provided on both sides of the hydraulic cylinder three, and an inner sleeve is slidably disposed within the outer sleeves. The clamping plate is fixedly connected to the inner sleeve, and a connecting rod is connected to one end of the inner sleeve. The piston rod of the hydraulic cylinder three is hinged to the connecting rod. The hydraulic cylinder three drives the connecting rod, thereby causing the inner sleeve to slide within the outer sleeve, causing the clamping plate to support the purlin or disengage from the purlin.

[0013] Furthermore, two supports are provided on one side of the bracket, and each support has a hinge seat rotatably mounted on one side via a pivot. The flip plate is fixedly installed between the two hinge seats. The platform on the bracket rotates around the pivot.

[0014] The beneficial effects of this utility model through the above technical solution are as follows:

[0015] This invention changes the traditional method of installing photovoltaic panels on four purlins arranged at an angle. Instead, the photovoltaic panels are assembled on a platform, and then the purlins and support components are installed sequentially. Finally, the entire assembly is assembled with the pipe piles. The photovoltaic panels are laid with the platform as a reference before the purlins are assembled, 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 high-altitude work platforms. It facilitates construction and installation, quickly avoids construction errors during photovoltaic bracket construction, effectively improves the installation efficiency and quality of photovoltaic brackets, and effectively reduces installation costs.

[0016] In this invention, the platform is equipped with a first stop block, a second stop block, and a retaining plate. When laying photovoltaic panels, the photovoltaic panels are placed between two adjacent first stop blocks, and the outermost photovoltaic panel is placed between first stop block and second stop block. At this time, the light-receiving surface of the photovoltaic panel is in contact with the platform. When assembling purlins, the four purlins are placed sequentially on the upper and lower four rows of retaining plates, and the purlins are limited by hooks on the retaining plates. Through the above-mentioned structure, the photovoltaic panels are effectively prevented from falling off when flipping. Furthermore, when the platform is tilted to the right to the preset installation angle of the photovoltaic panels, on the one hand, the retaining plate is moved downward in the slide groove by the third hydraulic cylinder, and the retaining plate is disengaged from the purlins. On the other hand, the bottom surfaces of the upper row of first stop block and second stop block are both inclined, preventing the first stop block or second stop block from scratching the lower row of photovoltaic panels, which facilitates the disengagement of the platform from the photovoltaic panels in subsequent construction.

[0046] It is worth mentioning that the platform 5 is also provided with weight reduction holes 33.

[0047] The working principle of this utility model is as follows:

[0048] The specific construction steps are as follows:

[0049] Step 1: Adjust the stage 5 to the first state using the flipping component;

[0050] Step 2: Lay out the photovoltaic panel 40. Place the photovoltaic panel 40 between two adjacent blocks 1 6, and place the outermost photovoltaic panel 40 between block 1 6 and block 2 7.

[0051] Step 3: Assemble the purlins 41. Place the four purlins 41 on the upper and lower four rows of clamping plates 8 in sequence. The purlins 41 are limited by the hooks 9.

[0052] Step 4: Install the support components;

[0053] Step 5: Lift the platform 5 using the lifting assembly, then adjust the platform 5 to the second state using the flipping assembly, then move the platform 5 horizontally using the moving assembly until the pipe pile 50 is aligned with the position between the front column 43 and the rear column 44, and then lower the platform 5 using the lifting assembly until the crossbeam 45 in the support assembly contacts the pipe pile 50.

[0054] Step Six: Connect the support assembly to the pipe pile 50 using clamps;

[0055] Step 7: Drive the card plate 8 to slide downward in the slide groove 10 through the drive component, and the card plate 8 disengages from the purlin 41;

[0056] Step 7: Disconnect the platform 5 from the photovoltaic panel 40 by moving the component to complete the construction of the photovoltaic support.

[0057] In step two, the light-receiving surface of the photovoltaic panel 40 is attached to the carrier platform 5.

[0058] In this embodiment, the flipping component in steps one and three switches the stage 5 between two states. In the first state in step one, as follows: Figure 3 As shown, stage 5 tilts to the left; in the second state of step three, as... Figure 15 and Figure 18 As shown, the platform 5 is tilted to the right to the preset installation angle of the photovoltaic panel 40.

[0059] The installation sequence of the components in the support assembly in step four is as follows: inclined beam 42, front column 43, rear column 44, crossbeam 45, front diagonal brace 46, and rear diagonal brace 47.

[0060] In steps two and three, the photovoltaic panels 40 are laid with the platform 5 as a reference before the purlins 41 are assembled. This ensures that the mounting surface of the purlins 41 meets the flatness requirements for the installation of the photovoltaic panels 40. This avoids the need to repeatedly adjust the height of the support columns, the angle of the braces, and the position of the inclined beams on the high-altitude work platform. This facilitates construction and installation and can quickly avoid construction errors during the construction of the photovoltaic bracket.

[0061] It should be noted that the specific process of step six is ​​as follows: the upper clamp 48 and the lower clamp 49 are installed in sequence, and the upper clamp 48 and the lower clamp 49 are installed on the pipe pile 50 according to the height of the construction design; wherein, the middle part of the front column 43 and the rear column 44 in the support assembly are respectively connected to the connecting ear plates at both ends of the upper clamp 48, the front column 43 and the front diagonal brace 46 are connected to the connecting ear plate at one end of the lower clamp 49, and the rear column 44 and the rear diagonal brace 47 are connected to the connecting ear plate at the other end of the lower clamp 49.

[0062] The applicant would like to explain that during land construction, the base 1 is fixed to the ground and assisted by the hydraulic outrigger; during water operations, the base 1 is fixed to the construction vessel and then securely fixed to the pipe pile 50 by relying on the hull of the vessel. The purpose of both is to effectively suppress the risk of tilting during the construction of the device.

[0063] In summary, this utility model changes the traditional method of installing photovoltaic panels 40 by operating on four purlins 41 arranged at an angle. Instead, the photovoltaic panels 40 are assembled on the platform 5, and then the purlins 41 and support components are installed in sequence. Finally, the whole assembly is assembled with the pipe pile 50. This method is easier to construct and install, can quickly avoid construction errors during photovoltaic bracket construction, effectively improves the installation efficiency and quality of photovoltaic brackets, effectively reduces installation costs, and by fixing the base 1 to the ground or ship hull, it is applicable to photovoltaic bracket construction on land and water.
