Description

Technical Field

[0001] This invention relates to the field of photovoltaic module installation technology, and more specifically, to a multifunctional auxiliary transfer device for photovoltaic module installation. Background Technology

[0002] A single solar cell cannot be used directly as a power source. To use it as a power source, several individual cells must be connected in series and parallel and tightly packaged into a module. Photovoltaic modules (also called solar panels) are the core part of a solar power generation system. Photovoltaic modules need to be installed on designated brackets, which requires auxiliary transfer devices to transfer and install the photovoltaic modules to the designated location.

[0003] The prior art patent application CN209256233U discloses an auxiliary installation device for photovoltaic modules, including a walking mechanism, a conveying mechanism, and a material dropping mechanism. The walking mechanism is mounted on the inclined surface of the photovoltaic support and can move laterally on the photovoltaic support. The conveying mechanism is fixed relative to the walking mechanism and is used to transport the photovoltaic modules from the bottom to the top of the photovoltaic support. The material dropping mechanism is mounted on the walking mechanism and can move laterally relative to it, used to grab the photovoltaic modules on the conveying mechanism and drop them onto the photovoltaic support. The purpose of this utility model is to provide an auxiliary installation device for photovoltaic modules to reduce labor intensity, improve installation efficiency, and avoid the potential for microcracks caused by people stepping on the photovoltaic modules. However, this auxiliary installation device has certain drawbacks. Installing photovoltaic modules requires arranging four solar panels sequentially each time, and manual replenishment is required after arrangement. It cannot continuously move while installing solar panels. Furthermore, even after installation using suction cups, screws cannot be installed; personnel still need to carry tools and step on the panels to fix the screws to the mounting bracket, thus significantly reducing installation efficiency. Summary of the Invention

[0004] This invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. To overcome the aforementioned deficiencies of existing technologies, this invention provides a multifunctional auxiliary transport device for photovoltaic module installation. This addresses the issues raised in the background section, such as the need to arrange four solar panels sequentially for each installation, requiring manual replenishment after arrangement, the inability to continuously walk while installing solar panels, and the failure to install screws after suction cup installation, which necessitates personnel carrying tools to step on and secure the screws to the mounting bracket, thus significantly reducing installation efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional auxiliary transfer device for photovoltaic module installation, comprising a base frame, a concave support plate fixed on one side of the base frame, and a row of auxiliary mechanisms provided inside the concave support plate;

[0006] The auxiliary mechanism includes a drive motor installed inside a concave support plate, with a toothed ring concentrically mounted on the output end of the drive motor. The inner wall of the base frame has two symmetrically arranged support shafts, and the outer side of each support shaft has multiple adjustable collar pedals arranged from left to right to provide stepping positions for installers. A drive chain is fitted around the toothed rings, and a drive toothed ring and a limiting roller are installed inside the drive chain near its bottom. The multiple adjusting collar pedals are movably connected to the support shafts, and the outer wall of the support shafts is polished. The toothed ring is fixedly connected to the output end of the drive motor, and the toothed ring meshes with the drive chain for transmission. The limiting roller is located on the inner wall of the drive toothed ring and is fixedly connected. Both the limiting roller and the drive toothed ring are made of stainless steel.

[0007] Preferably, the bottom end of the base frame is located on the outer wall of the limiting rolling rod and is provided with a plurality of first ring shaft blocks arranged sequentially from left to right. The limiting rolling rod and the first ring shaft blocks are movably connected by bearings. A second ring shaft block is provided on one side of the first ring shaft block, and a rolling shaft is movably connected inside the second ring shaft block by bearings.

[0008] Preferably, a multi-point linkage assembly is fixedly provided at the bottom end of the base frame. The multi-point linkage assembly includes a limiting frame plate fixedly installed at the bottom end of the base frame, and a bidirectional transmission screw is installed inside the limiting frame plate. A threaded collar block and a threaded linkage block are sleeved on the outer wall of the bidirectional transmission screw. A servo drive motor for providing rotational force to the limiting frame plate is fixedly installed at one end of the bidirectional transmission screw, concentrically. A linkage L-shaped plate is fixed at the bottom end of the threaded collar block, and a pressing support plate is welded to the bottom end of the linkage L-shaped plate. Friction blocks are arranged equidistantly from left to right on the lower surface of the pressing support plate. The lower surface of the threaded linkage block is welded with a linkage plate, and a linkage support plate is installed below the linkage plate. Multiple extrusion rack blocks are arranged equidistantly from left to right at the bottom end of the linkage support plate. The threaded linkage block is located on one side of the threaded collar block, and both the threaded linkage block and the threaded collar block are threadedly connected to the bidirectional transmission screw. The two threads on the outer wall of the bidirectional transmission screw are opposite and symmetrically arranged. The adjacent friction blocks and extrusion rack blocks are staggered and symmetrically arranged with gaps between them. One end of the bidirectional transmission screw penetrates the inner wall of the limiting frame plate and extends to one side of the limiting frame plate.

[0009] Preferably, the top of the bottom frame is provided with a linkage material handling assembly. The linkage material handling assembly includes a protective frame set at the top of the bottom frame, and the inner wall of the protective frame is provided with two positioning support rods. A sliding support plate is slidably connected to the outer wall of the positioning support rods through bearings. A photovoltaic panel tilting plate for supporting multiple solar panels is installed on one side of the sliding support plate. An interval adjustment frame is welded to one side of the photovoltaic panel tilting plate. A linkage screw and a threaded block are provided inside the interval adjustment frame. A linkage bracket is fixed to the top of the threaded block. A plurality of sleeve shaft blocks are arranged equidistantly from top to bottom on one side of the linkage bracket. A rotating shaft with a top cross-sectional area larger than its bottom cross-sectional area is movably connected to the inside of each sleeve shaft block through a bearing. An inclined insertion block for spacing between two adjacent solar panels is welded to the outer wall of the rotating shaft block below the sleeve shaft block. A limit support plate is welded to one side of the linkage bracket below the inclined insertion block. The threaded block is threaded to the outer wall of the linkage screw. The top of the inclined insertion block is chamfered and polished.

[0010] The technical effects and advantages of this invention are as follows:

[0011] 1. This invention employs a row-type auxiliary mechanism that allows personnel to stand on multiple adjusting ring pedals within the base frame. The drive motor activates, driving the gear ring, which in turn drives the drive chain, which in turn drives the drive gear ring. A limiting rolling rod rolls along multiple photovoltaic supports. Following a left-to-right installation sequence, two adjusting ring pedals can be moved to the right, bringing them closer to the other three pedals and creating an installation gap. Personnel can then directly remove the solar photovoltaic panels and stand on the adjusting ring pedals to install them directly onto the supports. This row-by-row installation of the photovoltaic supports prevents damage to the panels from stepping on them. Furthermore, the rapid tightening of bolts by personnel in a row ensures secure installation. This allows for large-scale, one-time row installation, resulting in higher efficiency and speed, a lower damage rate to the solar photovoltaic panels, and improved safety for personnel during installation and use.

[0012] 2. This invention uses a multi-point linkage component to start a servo drive motor to drive a bidirectional transmission screw to rotate forward. The bidirectional transmission screw drives the threaded collar block to move to the right on the inner wall of the limiting frame plate, and the threaded linkage block moves to the left under the action of the thread. The extrusion support plate drives multiple friction blocks to move to the right, and the threaded linkage block drives the linkage plate to move the linkage support plate to the left. The linkage support plate drives multiple extrusion rack blocks to move to the left, realizing staggered extrusion. This can achieve staggered extrusion locking and fixing of multiple photovoltaic brackets, forming a multi-point linkage locking, increasing the locking contact area, improving stability, reducing the likelihood of shaking of the entire bracket, improving safety, ensuring stable installation by personnel, improving installation efficiency, and reducing the likelihood of shaking.

[0013] 3. This invention uses a linkage material handling assembly to cause the linkage screw to drive the threaded block to move to the left under the action of the thread. The linkage bracket drives the sleeve shaft block to move the rotating shaft. The tilting plug is inserted into the gap between two photovoltaic panels. In this way, multiple tilting plugs are inserted into the gaps between multiple solar panels. Personnel can insert their fingers into the gaps and rotate the solar panels upwards. This causes the tilting plug to drive the rotating shaft to rotate upwards inside the sleeve shaft block, thus tilting the solar panels. The solar panels can then be removed and placed in the required installation position. This allows for quick tilting and removal of solar panels from the gaps for installation. The batch removal of solar panels is more efficient and faster.

[0014] In summary, through the interaction of the above-mentioned multiple functions, the photovoltaic panels will not be damaged by being stepped on. At the same time, the installation is secured by personnel quickly tightening the bolts in rows. Large-scale row installation at one time results in higher installation efficiency and speed, and a lower damage rate of solar photovoltaic panels. The linkage of multiple locking points increases the locking contact area, resulting in higher stability and less swaying of the entire support structure, thus improving safety. It also ensures stable installation by personnel, further increasing installation efficiency and reducing swaying. The solar panels can be tilted and then removed for placement in the desired location. This allows for quick and easy removal of the solar panels by hand through the gaps, effectively improving installation efficiency and safety, and enabling multi-functional installation operations.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] As attached Figure 1-8 The diagram illustrates a multi-functional auxiliary transfer device for photovoltaic module installation. This device includes a row-mounted auxiliary mechanism, a multi-point linkage component, and a linkage material handling component. The arrangement of these mechanisms and components provides safety protection during photovoltaic module installation, facilitates rapid row-mounted installation, and enables multi-point staggered locking, achieving multiple functions. The specific structural configuration of each mechanism and component is as follows:

[0026] In some embodiments, as shown in the appendix Figure 1-3As shown, the auxiliary mechanism includes a drive motor 3 installed inside the concave support plate 2, and a toothed ring 4 is installed concentrically on the output end of the drive motor 3. The inner wall of the bottom frame 1 is provided with two symmetrically arranged support shafts 5, and the outer side of the support shafts 5 is provided with multiple adjustable collar pedals 6 arranged from left to right to provide stepping positions for installers. The toothed ring 4 is fitted with a drive chain 9. Inside the drive chain 9 and near its bottom position, a drive toothed ring 7 and a limiting rolling rod 8 are installed. The multiple adjusting collar pedals 6 are movably connected to the support shafts 5, and the outer wall of the support shafts 5 is polished. The toothed ring 4 is fixedly connected to the output end of the drive motor 3, and the toothed ring 4 meshes with the drive chain 9 for transmission. The limiting rolling rod 8 is located on the inner wall of the drive toothed ring 7 and is fixedly connected. Both the limiting rolling rod 8 and the drive toothed ring 7 are made of stainless steel.

[0027] In this embodiment, when installing photovoltaic panels in rows, personnel can stand on multiple adjusting ring pedals 6 in the base frame 1. When it is necessary to install solar panels, the controller on the concave support plate 2 can start the drive motor 3 to drive the gear ring 4. The gear ring 4 drives the drive chain 9 for transmission, and the drive chain 9 drives the drive gear ring 7. The drive gear ring 7 drives the limiting rolling rod 8 to rotate. In this way, the limiting rolling rod 8 rolls along multiple photovoltaic supports. When it moves to the position where the solar panel needs to be laid, the drive motor 3 can be stopped to lock the limiting rolling rod 8. Following the installation sequence from left to right, two adjusting ring pedals 6 can be moved to the right. In this way, the two adjusting ring pedals 6 begin to move closer to the positions of the other three adjusting ring pedals 6, thereby opening an installation gap. Personnel can directly pick up the solar photovoltaic panel and stand on the adjusting ring pedal 6 to install it directly on the support. Then, pushing one adjusting ring pedal 6 to the left will open another installation gap. Multiple gaps can be opened in this way.

[0028] In some embodiments, as shown in the appendix Figure 4-5 As shown, at the bottom end of the base frame 1, located on the outer wall of the limiting roller 8, there are multiple first set of ring shaft blocks 10 arranged sequentially from left to right. The limiting roller 8 and the first set of ring shaft blocks 10 are movably connected by bearings. A second set of ring shaft blocks 11 is provided on one side of the first set of ring shaft blocks 10. A rolling shaft rod 12 is movably connected inside the second set of ring shaft blocks 11 by bearings. This allows the limiting roller 8 to rotate inside the multiple first set of ring shaft blocks 10 when the base frame 1 moves, and the rolling shaft rod 12 to rotate inside the second set of ring shaft blocks 11. The rollers at the edge of the rolling shaft rod 12 press against the edges of both sides of the photovoltaic bracket, preventing them from pressing against the already installed solar panels.

[0029] In some embodiments, as shown in the appendix Figure 1 and attached Figure 4-6As shown, a multi-point linkage assembly is fixedly provided at the bottom end of the base frame 1. The multi-point linkage assembly includes a limiting frame plate 13 fixedly provided at the bottom end of the base frame 1, and a bidirectional transmission screw 14 is installed inside the limiting frame plate 13. A threaded collar block 15 and a threaded linkage block 16 are sleeved on the outer wall of the bidirectional transmission screw 14. A servo drive motor 17 for providing rotational force to the limiting frame plate 13 is fixedly installed at one end of the bidirectional transmission screw 14 with the same center. A linkage L-shaped plate 18 is fixed at the bottom end of the threaded collar block 15. An extrusion support plate 19 is welded to the bottom end of the linkage L-shaped plate 18. Friction blocks 20 are arranged equidistantly from left to right on the lower surface of the extrusion support plate 19. A linkage plate 21 is welded to the lower surface of the threaded linkage block 16. A linkage support bar plate 22 is installed below the linkage plate 21. Multiple extrusion rack blocks 23 are arranged equidistantly from left to right on the bottom end of the linkage support bar plate 22.

[0030] In this embodiment, when the bottom frame 1 is moved to the designated installation position, the servo drive motor 17 is started to drive the bidirectional transmission screw 14 to rotate forward. The bidirectional transmission screw 14 drives the threaded collar block 15 to move to the right on the inner wall of the limiting frame plate 13, and the threaded linkage block 16 moves to the left under the action of the thread. The threaded collar block 15 drives the linkage L-shaped plate 18 to move the extrusion support plate 19. The extrusion support plate 19 drives multiple friction blocks 20 to move to the right. Through the threaded linkage block 16, the linkage plate 21 drives the linkage support bar plate 22 to move to the left. The linkage support bar plate 22 drives multiple extrusion rack blocks 23 to move to the left. The friction blocks 20 and the extrusion rack blocks 23 move and extrude relative to each other.

[0031] In some embodiments, as shown in the appendix Figure 1 and attached Figure 7-8As shown, a linkage material handling assembly is provided at the top of the bottom frame 1. The linkage material handling assembly includes a protective frame 24 set at the top of the bottom frame 1, and two positioning support rods 25 are provided on the inner wall of the protective frame 24. A sliding support plate 26 is slidably connected to the outer wall of the positioning support rods 25 via bearings. A photovoltaic panel tilting plate 27 for supporting multiple solar panels is installed on one side of the sliding support plate 26. An interval adjustment frame 28 is welded to one side of the photovoltaic panel tilting plate 27. A linkage screw 29 and a threaded block 30 are provided inside the interval adjustment frame 28, and a linkage bracket 31 is fixed to the top of the threaded block 30. On one side, there are multiple sleeve shaft blocks 32 arranged equidistantly from top to bottom. Each sleeve shaft block 32 is movably connected to a rotating shaft 33 with a top cross-sectional area larger than its bottom cross-sectional area through a bearing. An inclined plug-in block 34 for separating two adjacent solar panels is welded to the outer wall of the rotating shaft 33 and below the sleeve shaft block 32. A limit support plate 35 is welded to one side of the linkage bracket 31 and below the inclined plug-in block 34. A threaded block 30 is threaded to the outer wall of the linkage screw 29. The top of the inclined plug-in block 34 is chamfered and polished.

[0032] In this embodiment, when picking up solar panels, a large number of solar panels can be stacked and tilted sequentially inside the tilted photovoltaic panel placement plate 27. Then, the linkage screw 29 is rotated, causing the threaded block 30 to move to the left under the action of the thread. At the same time, the threaded block 30 causes the linkage bracket 31 to move along the inner wall of the spacing adjustment frame 28. The linkage bracket 31 causes the sleeve shaft block 32 to move the rotating shaft 33. The rotating shaft 33 causes the tilted insertion block 34 to be inserted into the gap between two photovoltaic panels. In this way, multiple tilted insertion blocks 34 are inserted into the gaps between multiple solar panels, thus ensuring that each solar panel... Gaps are created between the solar panels, and the limiting support plate 35 can limit the tilting plug 34 at the bottom. The tilting plug 34 can only rotate upwards and not downwards. When a person picks up a solar panel, they can pull the photovoltaic panel tilting placement plate 27. The photovoltaic panel tilting placement plate 27 drives the sliding support plate 26 to move along the outer wall of the two positioning support rods 25, so that the photovoltaic panel tilting placement plate 27 can be moved to the position where the solar panel needs to be installed. In this way, a person can insert their fingers in the gap and rotate the solar panel upwards, so that the tilting plug 34 drives the rotating shaft 33 to rotate upwards inside the sleeve shaft block 32.
