Description

Technical Field

[0001] This invention belongs to the field of photovoltaic module assembly technology, and relates to an assembly device for photovoltaic panels and metal plates used in the processing of solar photovoltaic modules. Background Technology

[0002] In recent years, the application of solar photovoltaic power generation systems on buildings has become increasingly widespread. During installation, it is usually necessary to fix the photovoltaic panels to a metal plate, with the metal plate providing support and protection for the photovoltaic panels. Since photovoltaic panels need to receive sunlight, their installation positions are often high (such as the roof of a high-rise building). Therefore, the conventional practice is to first fix the metal plate to the predetermined position on the high-rise building, then use hoisting equipment to lift the photovoltaic panels to the metal plate, and finally, operators complete the assembly using bolts and other connectors.

[0003] Currently, the installation of photovoltaic panels mainly relies on cranes or lifting equipment. Traditional cranes mostly use slings for lifting. Because wind speeds are generally high above high-rise buildings, slings are prone to causing photovoltaic panels to sway under wind force, affecting positioning accuracy and posing serious safety hazards, potentially leading to collision damage or falling accidents. While rigid lifting devices such as hydraulic rods can be used, their limited lifting stroke makes them unsuitable for the high-altitude installation requirements of high-rise buildings. Furthermore, hydraulic rods are bulky; when a large lifting range is needed, their length increases significantly, resulting in an excessively large overall space requirement for the lifting device, making it unsuitable for use on space-constrained building rooftops or in construction environments.

[0004] To address the aforementioned problems, this invention proposes an assembly device for photovoltaic panels and metal plates used in the processing of solar photovoltaic modules. Summary of the Invention

[0005] To address the problems existing in the background technology, the present invention proposes an assembly device for photovoltaic panels and metal plates used in the processing of solar photovoltaic modules, in order to solve the technical problems of easy swinging of slings, limited lifting range of hydraulic rods, and large space occupation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an assembly device for photovoltaic panels and metal plates used in the processing of solar photovoltaic modules, comprising: a fixed box, wherein a first take-up roller is rotatably connected inside the fixed box; a limiting channel is provided at the bottom of the fixed box; a first chain link, comprising a plurality of sequentially hinged connecting blocks, the upper end of the first chain link being connected to the first take-up roller, and the lower end of the first chain link extending through the limiting channel to the outside of the fixed box and connected to a mounting base; the first chain link having a channel extending along its length direction; a steel cable, both ends of which are fixedly connected to the first take-up roller and the mounting base respectively, and the steel cable being distributed along the length direction of the first chain link; a second chain link, comprising a plurality of sequentially hinged locking blocks, one end of the second chain link being connected to a second take-up roller mounted on the mounting base, and the other end of the second chain link extending from the lower end of the first chain link into the channel; and a drive mechanism, mounted on the mounting base, for driving the locking blocks to slide along the channel inside the first chain link.

[0007] The lifting and lowering are achieved by taking in and releasing the first chain link and steel cable with the first take-up roller. At the same time, the sliding of the second chain link in the channel can make the first chain link turn into a rigid vertical state when it extends, so as to avoid swinging. When winding, the first chain link can be flexibly bent, which occupies little space.

[0008] Furthermore, a fixing sleeve is fixedly connected to one side of the connecting block, and the steel cable passes through the fixing sleeve.

[0009] The steel cable is kept in relative position with each connecting block by a fixing sleeve, so that the steel cable can independently bear the tensile force, avoid the stress at the hinge, and prevent breakage.

[0010] Furthermore, the length of the limiting channel is at least the sum of the lengths of the two connecting blocks, and the cross-sectional dimensions of the limiting channel are adapted to the cross-sectional dimensions of the connecting blocks.

[0011] The limiting channel provides guidance and limitation for the first chain link, ensuring that the connecting block at the exit remains vertical.

[0012] Furthermore, the channel includes a through hole formed on the connecting block and sliding grooves located on both sides of the through hole; the second hinge shaft between adjacent locking blocks is slidably engaged with the sliding groove.

[0013] The slide groove guides the second hinge shaft, ensuring that the second chain link slides smoothly in the channel and accurately pushes the locking block.

[0014] Furthermore, the mounting base is provided with a guide groove that slides with the second hinge shaft, and the guide groove is connected to the sliding groove in the connecting block.

[0015] The guide groove smoothly guides the second link bar inside the mounting base into the groove of the first link bar, ensuring an unobstructed transition of the second hinge shaft and enabling continuous sliding.

[0016] Furthermore, the driving mechanism includes a driving gear, which is rotatably connected to the mounting base, and the side of the locking block is fixedly connected with a plurality of meshing teeth that mesh with the driving gear.

[0017] The drive gear pushes the locking block to slide through the meshing teeth, which can precisely control the feed speed and direction of the second chain link, and work with the second take-up roller to keep the end locking block always within the limit channel.

[0018] Furthermore, the locking block has a non-linear cross-sectional shape with at least one bend, which restricts the relative rotation between adjacent connecting blocks at any sliding position.

[0019] The non-linear structure creates a fitting constraint between adjacent locking blocks, which can effectively prevent the connecting blocks from rotating and avoid the hinge shaft from breaking under stress, even if the second hinge shaft is located at the joint surface of the two connecting blocks.

[0020] Furthermore, adjacent connecting blocks are hinged together by a first hinge axis, and a slide is provided on the side of the channel away from the first hinge axis.

[0021] The slide is positioned far from the first hinge axis, which increases the distance between the second hinge axis and the first hinge axis, improves the anti-torsional lever arm, and enhances locking stability.

[0022] Furthermore, the mounting base is equipped with a pneumatic suction cup for mounting photovoltaic panels.

[0023] Pneumatic suction cups are used to adsorb and fix photovoltaic panels, enabling the grasping and release of photovoltaic panels, which facilitates hoisting and assembly.

[0024] Compared with existing technologies, the present invention has the following advantages: Through the sliding engagement of the first and second chain links, the extended portion can be switched to a rigid vertical state, effectively avoiding swaying caused by high-altitude winds and improving hoisting safety. The steel cable independently bears the tensile load, protecting the hinged structure of the first chain link.

[0025] After being rolled up, the overall volume is compact and takes up little space. Attached Figure Description

Detailed Implementation

[0046] 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.

[0047] like Figures 1-19 The diagram shows an assembly device for processing photovoltaic panels and metal plates for solar photovoltaic modules.

[0048] Example 1: The technical solution adopted in this invention is as follows: An assembly device for photovoltaic panels and metal plates used in the processing of solar photovoltaic modules, comprising a fixed box 1, a first chain link, a steel cable 10, a second chain link, and a drive mechanism. The fixed box 1 is fixedly installed on an external crane. A first winding roller 2 is rotatably connected inside the fixed box 1, and a limit channel 4 is provided at the bottom of the fixed box 1. A first motor for driving the first winding roller 2 to rotate is installed on the fixed box 1.

[0049] The first link is formed by hinged connections of multiple connecting blocks 5. Adjacent connecting blocks 5 are hinged together by a first hinge shaft 6, allowing the first link to be flexibly bent during winding. The uppermost connecting block 5 of the first link is hinged to the first winding roller 2. The lowermost connecting block 5 of the first link extends through the limiting channel 4 to the outside of the fixed box 1 and is fixedly connected to the mounting base 11.

[0050] A guide wheel 3 is rotatably installed inside the fixed box 1. The guide wheel 3 is used to guide the first chain link and introduce it into the limiting channel 4.

[0051] The length of the limiting channel 4 is at least the sum of the lengths of the two connecting blocks 5.

[0052] The cross-sectional dimensions of the limiting channel 4 are adapted to the cross-sectional dimensions of the connecting block 5. The limiting channel 4 guides and limits the connecting block 5, ensuring that the first chain link remains vertical at the exit.

[0053] The first link has a channel extending along its length. Specifically, the channel includes a through hole 7 formed in the connecting block 5 and grooves 8 located on both sides of the through hole 7. The grooves 8 are located on the side of the through hole 7 away from the first hinge shaft 6.

[0054] Both ends of the steel cable 10 are fixedly connected to the first take-up roller 2 and the mounting base 11, respectively, and the steel cable 10 is distributed along the length direction of the first chain link. Specifically, a fixing sleeve 9 is fixedly connected to one side of each connecting block 5, and the steel cable 10 passes through each fixing sleeve 9, such as... Figure 6, Figure 7 As shown. The steel cable 10 is used to bear the main pulling force when hoisting the photovoltaic panel, avoiding stress on the hinge joint of the first chain link.

[0055] The second link is formed by a plurality of locking blocks 14 hinged together in sequence. Adjacent locking blocks 14 are hinged to each other by a second hinge shaft 15. One end of the second link is connected to a second take-up roller 13 mounted on a mounting base 11, and the other end extends from the lower end of the first link into the channel. A second motor for driving the second take-up roller 13 is mounted on the mounting base 11.

[0056] like Figure 17 As shown, the mounting base 11 has a guide groove 17 that slides with the end of the second hinge shaft 15. Figure 17 As shown, the guide groove 17 is connected to the slide groove 8 in the first link. The second hinge shaft 15 is slidably connected in the guide groove 17 and the slide groove 8, so that the locking block 14 can smoothly slide from the inside of the mounting base 11 into the channel of the first link.

[0057] The drive mechanism is mounted on the mounting base 11 and is used to drive the locking block 14 to slide along the channel inside the first chain link. Figure 10 As shown, in this embodiment, the driving mechanism includes a driving gear 18, which is rotatably connected to the mounting base 11. A plurality of meshing teeth 16 are fixedly connected to the side of the locking block 14, and the driving gear 18 is meshed with the meshing teeth 16.

[0058] A third motor is mounted on the mounting base 11, and the output shaft of the third motor is fixedly connected to the drive gear 18.

[0059] Multiple pneumatic suction cups 12 are fixedly connected to the bottom of the mounting base 11 for adsorbing and fixing the photovoltaic panel.

[0060] Working principle: Initially, the mounting base 11 is close to the bottom of the fixed box 1, and the whole device is compact. The first chain link and the steel cable 10 are wound on the first winding roller 2, and the second chain link is wound on the second winding roller 13.

[0061] The first take-up roller 2 is controlled to rotate, unwinding the first chain link and the steel cable 10. Since the upper end of the first chain link is hinged to the first take-up roller 2 and the lower end is connected to the mounting base 11, the unwinding of the first take-up roller 2 causes the mounting base 11 to move downwards as a whole, while the steel cable 10 is unwound synchronously. Simultaneously, the second take-up roller 13 and the drive gear 18 are controlled to rotate, unwinding the second chain link. At the same time, the drive gear 18 engages with the meshing teeth 16 on the side of the locking block 14, pushing the second chain link upwards along the guide groove 17 on the mounting base 11 and the sliding groove 8 in the connecting block 5.

[0062] As the second take-up roller 13 unwinds and the drive gear 18 rotates, the end of the second link is continuously fed into the channel of the first link.

[0063] By controlling the unwinding speed of the second take-up roller 13 and the conveying speed of the drive gear 18, the locking block 14 at the very end of the second chain link is always kept within the limiting channel 4 area at the bottom of the fixed box 1. Figure 12 As shown.

[0064] As the first link extends, the channel inside the first link located outside the fixed box 1 is gradually filled by the second link. The first link located outside the fixed box 1 maintains a rigid vertical position, and even if the first link is subjected to lateral wind force, the adjacent connecting blocks 5 cannot rotate relative to each other. Therefore, the swaying problem of traditional slings is effectively avoided.

[0065] When the mounting base 11 descends to the predetermined height (the position where the photovoltaic panel is placed), the first winding roller 2, the second winding roller 13, and the drive gear 18 are stopped rotating. Multiple pneumatic suction cups 12 at the bottom of the mounting base 11 are activated to firmly adhere the photovoltaic panel.

[0066] The first take-up roller 2 is controlled to rotate, winding up the steel cable 10 and the first chain link. At this time, the steel cable 10 directly bears the gravitational pull of the photovoltaic panel, while the hinge point of the first chain link (first hinge shaft 6) is basically not under tension, thus avoiding the risk of breakage due to the poor stress capacity of the hinge structure. At the same time, the second take-up roller 13 is controlled to rotate, and the gear 18 is driven to rotate in the opposite direction, driving the second chain link to move along the slide groove 8 and guide groove 17 towards the mounting base 11. And the locking block 14 at the very end of the second chain link is always kept within the area of ​​the limiting channel 4.

[0067] During the ascent, the channel inside the first chain link located outside the fixed box 1 is always filled by the second chain link. Therefore, the first chain link continues to maintain a rigid vertical state, and the photovoltaic panel will not sway due to wind force during the ascent, moving upward safely and stably.

[0068] When the photovoltaic panel is hoisted to the metal plate installation position, the first winding roller 2, the second winding roller 13, and the drive gear 18 are stopped rotating. Then, the pneumatic suction cup 12 is turned off, detaching the photovoltaic panel from the mounting base 11. Subsequently, the workers use bolts and other connectors to fix the photovoltaic panel to the metal plate.

[0069] After one hoisting operation is completed, the first winding roller 2 and the second winding roller 13 can be controlled to continue winding and the drive gear 18 can be rotated, so that the mounting base 11 is back attached to the bottom of the fixed box 1, and the device returns to a compact winding state, which is convenient for moving or carrying out the next hoisting operation.

[0070] Example 2: This example is an improvement based on Example 1.

[0071] In this embodiment, as Figure 15 , Figure 16 As shown, the locking block 14 has a non-linear structure, specifically including a first vertical segment, a second vertical segment, and a horizontal segment. One end of the horizontal segment is fixedly connected to the lower end of the first vertical segment, and the other end is fixedly connected to the upper end of the second vertical segment.

[0072] Between two adjacent locking blocks 14, the first vertical segment of one locking block 14 engages with the second vertical segment of the other locking block 14, and the horizontal segment of one locking block 14 is connected to one end of the other locking block 14 via a second hinge shaft 15. Thus, when the second link is fed into the channel of the first link, the second hinge shaft 15 can stably lock the second link regardless of its position within the channel, preventing relative rotation of the connecting blocks 5. Figure 18 The diagram shows the structure of the locking block 14 in the first state within the channel, at which point the second hinge shaft 15 is located on the contact surface between two adjacent connecting blocks 5. Figure 19 This is a schematic diagram of the locking block 14 in its second state within the channel. When an external force is applied to the connecting block 5, the mating part or the main body of the locking block 14 preferentially bears the lateral force, so that the first hinge shaft 6 or the second hinge shaft 15 hardly bears the shear load, thereby avoiding breakage due to stress concentration. This design effectively prevents the risk of the second hinge shaft 15 or the first hinge shaft 6 breaking under stress, significantly improving the safety and reliability of the hoisting process.

[0073] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
