Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic shed construction, and in particular to a photovoltaic shed construction method and operation and maintenance channel. Background Art

[0002] Photovoltaic trellis is a trellis installed with photovoltaic panels; the photovoltaic panels installed on it can convert solar energy into electrical energy for use by the load.

[0003] At present, most factories are built with steel structures, and most of the factory roofs are capped with colored steel tiles. As the factory ages, the colored steel tile roofs are often accompanied by obvious damage and water leakage. However, if the colored steel tiles are replaced on a large scale, it is not only expensive, but also fails to solve the fundamental problem. For this reason, photovoltaic sheds are often built on the colored steel tile roofs. Photovoltaic sheds are not only conducive to the use of sunlight, converting light energy into electrical energy for factory use, but also can block the original colored steel tile roof and reduce water leakage.

[0004] During the use of photovoltaic sheds, it is often necessary to perform daily maintenance on the photovoltaic modules on the roof. However, since the photovoltaic modules are installed at an angle on the roof and there are few footholds on the photovoltaic shed, it is not only difficult to perform maintenance work, but also easy to step on the photovoltaic modules and damage them. What's more, maintenance personnel are prone to fall from the roof of the photovoltaic shed. Summary of the invention

[0005] In order to improve the convenience and safety of maintenance on photovoltaic sheds, the present application provides a photovoltaic shed construction method and operation and maintenance channel.

[0006] In the first aspect, the present application provides a photovoltaic shed construction method, which adopts the following technical solution:

[0060] S4.5: Buckle the two ends of the operation and maintenance channel 6 onto the symmetrical sides of the pressure code 4.

[0061] The photovoltaic modules 5 are supported by the M-shaped guide rails 2, the middle support 3 and the pressure codes 4. While supporting the photovoltaic modules 5, the operation and maintenance channel 6 is fastened to the top surfaces of two adjacent photovoltaic modules 5 so that the photovoltaic shed can be inspected and maintained through the operation and maintenance channel 6.

[0062] Second, see Figure 4 An operation and maintenance channel includes the operation and maintenance channel 6 in step S4, wherein both ends of the operation and maintenance channel 6 are fixedly connected with support seats 7, and opposite sides of the two support seats 7 are fixedly connected with buckle plates 8.

[0063] When the operation and maintenance channel 6 needs to be installed, the buckle plate 8 is buckled between the pressure code 4 and the photovoltaic module 5, and then the bolts corresponding to the pressure code 4 are tightened. At this time, the operation and maintenance channel 6 is fixed to the top surface of the photovoltaic shed.

[0064] See also Figure 4 and Figure 5In order to increase the walking range of maintenance personnel on the operation and maintenance channel 6 and increase the foothold, an auxiliary component is installed in the support seat 7, and the auxiliary component includes an extension channel 9, and the number of the extension channels 9 is set in two groups, and the number of each group of extension channels 9 is set in two. The two sides of the support seat 7 are symmetrically provided with accommodating grooves 10, and the number of the accommodating grooves 10 corresponds to the extension channels 9. Each extension channel 9 is hinged in each accommodating groove 10, and the hinged end of the extension channel 9 is the end close to the two extension channels 9 in each group.

[0065] At the same time, the support seat 7 is also equipped with a positioning member, which is used to simultaneously position and fix the positions of the two extension channels 9. The positioning member is a limiting rod 11, and the top surfaces of the two extension channels 9 are provided with a slide groove 12, and the two ends of the limiting rod 11 slide in the slide groove 12 respectively. The side wall of the support seat 7 is also provided with an embedding groove 13, which is located between the two accommodating grooves 10, and the two ends of the embedding groove 13 are respectively connected to the accommodating groove 10. The limiting rod 11 is plugged into the embedding groove 13.

[0066] When the extension channel 9 needs to be unfolded, the two extension channels 9 are first swung out of the accommodating groove 10, and the extension channels 9 are perpendicular to the support seat 7. Then the limiting rod 11 is taken out of the embedding groove 13, and the limiting rod 11 slides in the sliding groove 12. Under the limiting effect of the limiting rod 11, the two extension channels 9 are positioned and fixed at the current position.

[0067] See also Figure 5 In order to fix the limit rod 11, the limit rod 11 has adjustment grooves 14 at both ends, and the adjustment grooves 14 are slidably connected with the insertion rods 15. The extension channel 9 has slots 16 on the groove wall based on the slide groove 12. The number of the slots 16 is multiple, and the multiple slots 16 are respectively distributed in a linear array along the length direction of the extension channel 9. One end of the insertion rod 15 extends outside the rod end of the limit rod 11, and one end of the insertion rod 15 is respectively plugged into the slots 16.

[0068] At the same time, in order to improve the stability of the insertion rod 15 inserted into the slot 16, the limit rod 11 is installed with an elastic member, which is a spring 17. The side wall fixing ring of the insertion rod 15 is provided with a pressing ring 18, and the pressing ring 18 slides in the adjustment groove 14. One end of the spring 17 is fixedly connected to the pressing ring 18, and the other end of the spring 17 is fixedly connected to the groove wall of the adjustment groove 14.

[0069] When the limit rod 11 needs to be moved, the rod 15 is first moved away from the slot 16, and the rod 15 is pressed against the spring 17 through the pressure ring 18, and the position of the limit rod 11 can be adjusted. When the rod 15 is released, the spring 17 releases its elastic force and drives the rod 15 to be inserted into the slot 16 through the pressure ring 18.

[0070] It should be noted that in addition to positioning and fixing the two extension channels 9, the limit rod 11 is also used to provide a foothold for maintenance personnel, and the position of the foothold is adjusted by adjusting the position of the limit rod 11, thereby improving the convenience of adjusting the maintenance range.

[0071] See also Figure 6 In order to prevent the extension channel 9 from bending and deforming when construction workers step on the extension channel 9, a vertical groove 19 is opened on the bottom surface of the extension channel 9 away from the hinge, and a wedge-shaped pad 20 is slidably installed in the vertical groove 19, and the bottom end of the wedge-shaped pad 20 extends outside the vertical groove 19.

[0072] See also Figure 6 In order to facilitate the movement of the wedge-shaped pad 20, a lifting member is installed in the extension channel 9, and the lifting member is a screw 21. The screw 21 is threadedly connected to the extension channel 9, and the bottom end of the screw 21 extends into the vertical groove 19, and the bottom end of the screw 21 is rotatably connected to the top surface of the wedge-shaped pad 20.

[0073] When the extension channel 9 is swung out, the extension channel 9 is perpendicular to the inspection channel, and the screw rod 21 is rotated in the reverse direction, and the screw rod 21 drives the wedge-shaped pad 20 to descend. At this time, the wedge-shaped pad 20 is supported on the top surface of the photovoltaic module 5. When the screw rod 21 is rotated in the forward direction, the screw rod 21 drives the wedge-shaped pad 20 to rise, and when the wedge-shaped pad 20 is completely raised, the bottom end of the wedge-shaped pad 20 is placed outside the bottom of the extension channel 9. When the extension channel 9 is reset and swung in the receiving groove 10, the wedge surface of the wedge-shaped pad 20 is pressed against the receiving groove 10, and the wedge-shaped pad 20 is inserted into the receiving groove 10 with an interference fit, so that the extension channel 9 is fixed in the receiving groove 10.

[0074] It is worth mentioning that the inner side of the operation and maintenance channel 6 is fixedly connected with reinforcing ribs, and the number of reinforcing ribs is set to at least two. Under the action of the reinforcing ribs, the overall strength of the operation and maintenance channel 6 is improved.

[0075] The working principle of an operation and maintenance channel:

[0076] When the photovoltaic module 5 needs to be repaired, walk on the photovoltaic shed through the operation and maintenance channel 6 to walk to the location of the photovoltaic module 5 that needs to be repaired. When it is necessary to increase the foothold and widen the maintenance range, first swing the extension channel 9 out of the accommodating groove 10 to make the two extension channels 9 perpendicular to the operation and maintenance channel 6, and then slide the limit rod 11 out of the embedded groove 13. Under the restriction of the limit rod 11 and the groove wall of the accommodating groove 10, the two extension channels 9 are fixed at the current position. In addition, in the process of swinging out the extension channel 9, the screw 21 is tightened forward, and the screw 21 drives the wedge-shaped pad 20 to descend, so that the wedge-shaped pad 20 abuts against the top surface of the photovoltaic module 5, thereby supporting the extension channel 9. At this time, the maintenance personnel can stand on the top surface of the extension channel 9 or the limit rod 11, and then repair the photovoltaic module 5.

[0077] When the position of the foothold needs to be changed, the insertion rod 15 is pulled away from the slot 16, and the insertion rod 15 compresses the spring 17 through the pressure ring 18. At this time, the insertion rod 15 is separated from the slot 16, and the position of the limit rod 11 can be slidably adjusted. When the limit rod 11 slides to the desired position, the card insertion rod 15 is released, the spring 17 releases the elastic force, and drives the insertion rod 15 to be inserted into the slot 16 through the pressure ring 18. At this time, the limit rod 11 is fixed at the current position, so that the position of the foothold can be changed by adjusting the position of the limit rod 11.

[0078] In summary, walking on the photovoltaic shed through the operation and maintenance channel 6 improves the convenience of overhauling the photovoltaic components 5. It reduces stepping on the photovoltaic components 5, avoids slipping from the photovoltaic shed, and improves the safety of overhauling the photovoltaic shed.

[0079] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
