Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and in particular to auxiliary installation equipment of photovoltaic modules. Background Art

[0002] In the prior art, during the laying process of photovoltaic modules, the photovoltaic modules are usually laid on support frames. Since the overall height of some support frames is relatively high, during the laying process, personnel at the bottom of the frame are required to take the photovoltaic modules to the installation position, and then pass them from a low place to a high place. Then, the laying personnel on the frame install the photovoltaic modules at the designated position.

[0003] Therefore, during the laying process, the workers' workload is relatively high, and when transferring photovoltaic modules from the ground to a high place for installation, there is also the possibility that the photovoltaic modules may fall during the transfer process, which will not only threaten the safety of the workers, but also cause the photovoltaic modules to be damaged.

[0004] If a lift is used to transfer photovoltaic modules, since the overall height of the support frame of different installation projects is different, it is necessary to adapt to lifts of various specifications. If a large-sized lift is selected, it is not only inconvenient to transport, but also occupies a large area during installation, thus being constrained. Summary of the invention

[0005] The content of the present invention is used to introduce the concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of the present disclosure is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0006] Some embodiments of the present invention provide auxiliary installation equipment for photovoltaic modules to solve the technical problems mentioned in the above background technology section.

[0007] The auxiliary installation device of the photovoltaic module comprises a bracket, on which a symmetrically arranged fixing plate is fixedly connected, a fixing frame is slidably buckled on the top of the fixing plate, and a sliding frame slidably connected to the fixing plate is provided below the fixing frame;

[0008] Large sprockets are provided on both sides of the opposite inner walls of the two fixed plates; large sprockets are provided on both sides of the opposite inner walls of the fixed frame; and one large sprocket is provided on the two opposite inner walls of the sliding frame; the five large sprockets on each side are meshed and connected with a large chain, and each of the large chains is connected with a bracket for carrying a photovoltaic module;

[0009] The bottom ends of both sides of the sliding frame are connected with tension springs, and the other ends of the tension springs are fixedly connected to the fixing plate.

[0010] The above-mentioned embodiments of the present invention have the following beneficial effects: through the auxiliary installation device of the photovoltaic module of the present invention, the height of the device can be flexibly adjusted, so that it can be flexibly adapted to support frames of different heights, so that it can be applicable to various installation projects.

[0011] Specifically, as the fixing frame rises relative to the fixing plate, the large chain is pulled upward, and since the large chain is also engaged with the large sprocket on the sliding frame, a downward force is applied to the large sprocket, thereby compressing the tension spring. In this way, when the height of the fixing frame is adjusted, the tension state of the large chain can be ensured, thereby improving the reliability of lifting the photovoltaic module.

[0023] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0024] See also Figures 1 to 5 , Figure 1 It is a structural schematic diagram of an embodiment of the auxiliary installation device of the photovoltaic module of the present invention; Figure 2 A cross-sectional view of an embodiment of an auxiliary installation device for a photovoltaic module of the present invention; Figure 3 for Figure 2 The enlarged view of point A in the middle; Figure 4 is a cross-sectional view of an embodiment of a fixing frame of the present invention; Figure 5 FIG. 2 is a cross-sectional view of an embodiment of a fixing seat of the present invention. Figure 1 and Figure 2 As shown, the auxiliary installation equipment of the photovoltaic module includes a bracket 1, the top left side of the bracket 1 ( Figure 2 A controller 2 is provided, and a battery 3 is connected to the bottom left end of the bracket 1. Figure 1 A symmetrically arranged fixing plate 4 is fixedly connected thereto (in the direction in the middle), a fixing frame 5 is slidably buckled on the top of the fixing plate 4, and a sliding frame 6 slidably connected to the fixing plate 4 is provided below the fixing frame 5.

[0025] like Figures 2 to 4 As shown, large sprockets 8 are respectively provided on both sides of the bottom end of each fixed plate 4. Large sprockets 8 are respectively provided on both sides of the two opposite inner walls of the fixed frame 5. In addition, a large sprocket 8 is provided on each of the two inner walls of the sliding frame 6. Two fixed shafts 7 are also pivotally provided at the bottom ends of the two fixed plates 4, and two oppositely arranged large sprockets 8 are sleeved on one fixed shaft 7. Two fixed shafts 7 are pivotally provided between the two inner walls of the above-mentioned fixed frame 5, and two oppositely arranged large sprockets 8 are sleeved on one fixed shaft 7. A fixed shaft 7 is pivotally provided between the two inner walls of the above-mentioned sliding frame 6, and two oppositely arranged large sprockets 8 are sleeved on the fixed shaft 7.

[0026] like Figure 2 As shown, the outer sides of the five large sprockets 8 on each side are meshed with large chains 9, that is, the large chains 9 are meshed with the two large sprockets 8 on the fixed frame 5 and the left side of the fixed plate 4 ( Figure 2 The large chain 9 is upwardly sleeved on the large sprocket 8 on the sliding frame 6 and then downwardly engaged with the right side of the fixed plate 4 ( Figure 2 The large sprocket 8 (in the direction of the center) is engaged.

[0027] The two large chains 9 are on the lower right outside ( Figure 2 The fixing plate 4 is fixedly connected to the fixing rod 14. The fixing rod 14 is connected to the bracket 15 on the outside. Figure 2 A fixing seat 16 is provided on the bracket 1 at a position (in the direction in the middle), and the fixing seat 16 is slidably connected to the bracket 1. The top of the fixing seat 16 is slidably connected to a limiting plate 17, and a photovoltaic component 18 is inserted into the top of the limiting plate 17.

[0028] like Figure 2-4 As shown, in order to solve the problem that the tension of the large chain 9 cannot be guaranteed after the height of the fixed frame 5 is adjusted, the bottom ends of both sides of the sliding frame 6 are connected with tension springs 10, and the other end of the tension spring 10 is fixedly connected to the fixed plate 4. In this way, the tension spring 10 can provide an upward force to the sliding frame 6, the fixed shaft 7 and the two large sprockets 8 in the sliding frame 6, so that the large chain 9 is in a tensioned state.

[0029] When the height of the fixed frame 5 is adjusted, due to the lifting of the four large sprockets 8 in the fixed frame 5, the sliding frame 6 can compress or pull the tensioning spring 10 through the large chain 9, the large sprocket 8 in the sliding frame 6 and the corresponding fixed shaft 7, thereby ensuring the tension of the large chain 9 after the equipment height is adjusted.

[0030] like Figure 1-4 As shown, in actual work, the transmission of the large chain 9 can drive the bracket 15 to rise, so that the bracket 15 can lift the photovoltaic module 18. In order to improve the stability of the bracket 15 when it is lifted, the top of the sliding frame 6 is fixedly connected to the driving motor 11, and the main shaft end of the driving motor 11 is fixedly connected to the worm 12, and the outer side of the worm 12 is meshed with the worm wheel 13, and the worm wheel 13 is fixedly sleeved to the middle of the fixed shaft 7 in the sliding frame 6. The driving motor 11 drives the worm 12 and the worm wheel 13, so that the fixed shaft 7 in the sliding frame 6 drives the large sprockets 8 on both sides to rotate, so that the chain 9 and other large sprockets 8 rotate synchronously, and then the two brackets 15 are lifted synchronously, and the photovoltaic module 18 on the far left can be lifted upward. Therefore, the self-locking property of the worm 12 meshing with the worm wheel 13 is used to ensure the stability of the bracket 15 after lifting the photovoltaic module 18.

[0031] like Figure 2 As shown, the bracket 15 is arranged in a U shape, and the bracket 15 is fixedly connected to the fixing rod 14. By controlling the bracket 15 arranged in a U shape to lift the photovoltaic assembly 18, the photovoltaic assembly 18 has better stability after being lifted.

[0032] like Figure 1 and Figure 5 As shown, in order to solve the problem of adjusting the distance between the two limit plates 17 according to the size of the photovoltaic module, the bottom end of the limit plate 17 is spirally connected with a fixed threaded shaft 19, and the fixed threaded shaft 19 is rotatably connected to the fixing seat 16. By rotating the fixed threaded shaft 19, the limit plate 17 can slide relative to the fixing seat 16, so that the distance between the two limit plates 17 can be adjusted according to the size of the photovoltaic module 18.

[0033] like Figure 2 and 5As shown, in order to solve the problem of inconvenience in continuous transfer of photovoltaic components 18, a mobile motor 20 is arranged under each fixed seat 16, and the main shaft of the mobile motor 20 is fixedly connected with a positioning threaded shaft 21, and the positioning threaded shaft 21 is rotatably connected to the bracket 1. The positioning threaded shaft 21 is sleeved with a slide bar 22, and the slide bar 22 is slidably connected to the bracket 1, and the slide bar 22 is also fixedly connected to the fixed seat 16. After completing one transfer of the photovoltaic component 18 and resetting the bracket 15, the positioning threaded shaft 21 is driven to rotate by controlling the mobile motor 20, so that the slide bar 22 drives the fixed seat 16 and the limit plate 17 to move a fixed distance to the left, thereby controlling the photovoltaic component 18 outside the limit plate 17 to move to the left ( Figure 2 In the direction of the bracket 15, the photovoltaic components 18 are moved a fixed distance, and when the next photovoltaic component 18 to be transferred is moved to the top of the bracket 15, the photovoltaic components 18 are transferred continuously.

[0034] like Figure 2 As shown, in order to solve the problem that the moving motor 20 cannot be automatically controlled to stop when the fixing seat 16 and the limit plate 17 are reset after the photovoltaic assembly 18 is completely transferred, the right end of the sliding rod 22 ( Figure 2 The control switch 23 is fixedly connected to the bracket 1 (in the direction of the center). By controlling the mobile motor 20 to reverse, the fixing seat 16 and the limit plate 17 are reset after the photovoltaic assembly 18 is completely transferred. The control switch 23 is engaged with the bracket 1 by sliding the slide bar 22 to the right, triggering the control switch 23, and then controlling the mobile motor 20 to stop working.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, in order to solve the problem that it is inconvenient to adjust the height of the fixing frame according to the transfer height of the photovoltaic module 18, an adjusting threaded shaft 24 is spirally connected in the two fixing plates 4. The top end of the adjusting threaded shaft 24 passes through the fixing frame 5 and is connected to the height adjustment motor 25, and the height adjustment motor 25 is fixedly connected to the upper end of the fixing frame 5. The height adjustment motor 25 can be controlled by the controller 2 to drive the adjusting threaded shaft 24 to rotate, so that the fixing frame 5 slides upward relative to the fixing plate 4. At this time, the large chain 9 is stretched, and the large sprocket 8 in the sliding frame 6 and the corresponding fixed shaft 7 compress the tensioning spring 10 downward, thereby completing the adjustment of the height of the fixing frame according to the height that the photovoltaic module 18 needs to transfer.

[0036] like Figure 2 and Figure 4As shown, in order to solve the problem that it is inconvenient to control the fixing frame 5 to slide up and down stably on the outside of the fixing plate 4, a small sprocket 26 is fixedly mounted on the top of the two adjusting threaded shafts 24, and a small chain 27 is meshed and connected on the outside of the two small sprockets 26. In the process of controlling the fixing frame 5 to slide up and down on the outside of the fixing plate 4, the adjusting threaded shafts 24 on both sides are simultaneously controlled to rotate under the meshing of the small sprocket 26 and the small chain 27, so that the fixing frame 5 can slide up and down stably on the outside of the fixing plate 4.

[0037] In this embodiment, when the staff is laying the photovoltaic module 18, they first rotate the fixed threaded shaft 19 to move the limit plate 17, so that the distance between the two limit plates 17 can be adjusted according to the size of the photovoltaic module 18. After the adjustment, the controller 2 controls the height adjustment motor 25 to rotate, and then drives the two adjustment threaded shafts 24 to rotate through the small sprocket 26 and the small chain 27, so that the fixed frame 5 slides upward on the outside of the fixed plate 4. At this time, the large chain 9 is stretched, and the large sprocket 8 and the corresponding fixed shaft 7 in the sliding frame 6 compress the tension spring 10 downward, so that the height of the fixed frame 5 can be adjusted according to the height that the photovoltaic module 18 needs to transfer. After adjusting the height, insert the photovoltaic assembly 18 between the two limit plates 17, and then push the auxiliary installation equipment to the laying position of the photovoltaic assembly 18, and then control the driving motor 11 through the controller 2 to drive the worm 12 and the worm wheel 13, at this time, the worm wheel 13 drives the fixed shaft 7 in the fixed seat 6 to drive the corresponding large sprocket 8 and the large chain 9 to rotate, so that the other large sprockets 8 rotate synchronously, so that the large chain 9 can drive the U-shaped bracket 15 on the right side of the fixed rod 14 to lift the photovoltaic assembly 18 on the left. When the photovoltaic assembly 18 on the left is lifted to the specified height, the staff on the laying support frame can remove the photovoltaic assembly 18 for laying. After the photovoltaic assembly 18 is removed, the driving motor 11 is controlled by the controller 2 to reverse and reset the bracket 15, and then the moving motor 20 is controlled by the controller 2 to drive the positioning threaded shaft 21 to rotate, so that the slide bar 22 drives the fixed seat 16 and the limit plate 17 to move a fixed distance to the left, thereby controlling the photovoltaic assembly 18 outside the limit plate 17 to move a fixed distance to the left. At this time, the next photovoltaic module 18 to be transferred can be moved to the top of the bracket 15, and then the above operation can be repeated to continue transferring the photovoltaic modules 18. When the photovoltaic modules 18 are completely transferred, the controller 2 is used to control the moving motor 20 to reverse and reset. At this time, when the slide bar 22 slides to the right and triggers the control switch 23, the moving motor 20 will automatically stop, and then the photovoltaic modules 18 are replenished and the staff can continue to transfer the photovoltaic modules 18.
