[0002] During the operation and maintenance of photovoltaic (PV) modules, staff need to regularly clean, inspect, and maintain them. Traditional maintenance methods typically involve staff walking directly on the corrugated steel roof, posing several safety hazards: First, the surface of the corrugated steel roof is slippery, especially in damp or dusty conditions, making staff prone to slipping and falling. Second, the PV module cables are often haphazardly placed on the roof, not only hindering staff movement but also potentially causing tripping accidents. Furthermore, cleaning PV modules requires tools and equipment, and the lack of a stable operating platform could lead to equipment slippage or staff loss of balance. Therefore, there is an urgent need for a device that provides a safe and stable maintenance path while also managing cables in a standardized manner to improve the safety of staff during PV module maintenance.

[0043] During the operation and maintenance of photovoltaic (PV) modules, staff need to regularly clean, inspect, and maintain them. However, traditional maintenance methods often lack dedicated access routes, forcing staff to walk directly on corrugated steel roofs, posing several safety hazards: First, the smooth surface of corrugated steel roofs, especially in damp or dusty conditions, makes staff prone to slipping and falling; second, PV module cables are often haphazardly laid out on the roof, not only hindering staff movement but also potentially causing tripping accidents; furthermore, the lack of a stable platform for tools and equipment used for cleaning PV modules could lead to equipment slippage or staff loss of balance. Therefore, there is an urgent need for a device that provides a safe and stable access route while also managing cables in a standardized manner to improve the safety of staff during PV module maintenance.
[0044] In view of this, see Figures 1 to 5 The rooftop photovoltaic module maintenance channel provided in this embodiment of the utility model is installed on a roof with photovoltaic modules and includes an anti-slip plate, a mounting frame 2, and multiple support members 3. The anti-slip plate and the mounting frame 2 are both rectangular, and the anti-slip plate and the mounting frame 2 are arranged side by side along their length. Multiple support members 3 are arranged at intervals along the length of the anti-slip plate, and the anti-slip plate and the mounting frame 2 are both installed on the support members 3. The support members 3 are used for installation on the roof, the surface of the anti-slip plate has a water-guiding structure, and the mounting frame 2 is used to accommodate the cables 7 extending from the photovoltaic modules.
[0045] Specifically, photovoltaic modules are installed on the roof, and an anti-slip plate is installed adjacent to the photovoltaic modules on the roof; in this embodiment, the distance between the photovoltaic modules and the anti-slip plate is less than or equal to 300mm, such as 100mm, 150mm, or 300mm. Further, see... Figure 4 The support member 3 is set as a U-shaped square steel. The bottom wall of the U-shaped square steel is provided with a first mounting hole. The bolt passes through the bottom wall of the mounting frame 2 and the bottom wall of the U-shaped square steel in sequence and is connected to the nut to realize the mounting frame 2 being installed on the support member 3.
[0046] The rooftop photovoltaic module maintenance access is installed on the roof with photovoltaic modules and is located close to the photovoltaic modules. Support member 3 is installed on the roof, and anti-slip plate and mounting bracket 2 are installed on support member 3. Support member 3 provides support for anti-slip plate and mounting bracket 2. The surface of anti-slip plate has a water-guiding structure, which can guide water away from the surface of anti-slip plate in time to avoid the surface of anti-slip plate being wet and slippery. The water-guiding structure can also enhance the surface roughness of anti-slip plate to further achieve the anti-slip function. Anti-slip plate can also be used as a pedestrian walkway, as its dry and rough surface prevents workers from falling when walking. Anti-slip plate can also be used as an operating platform, and the water-guiding structure can be used to place operating tools to prevent operating tools from falling. Mounting bracket 2 is used to place the photovoltaic module cables 7.
[0047] During the cleaning, inspection and maintenance of photovoltaic modules, the staff can walk on the anti-slip plate, which can prevent them from slipping and falling due to the wet corrugated steel roof. The anti-slip plate can also serve as a stable operating platform. The mounting frame 2 can manage the cable 7 in a standardized manner, ensuring the safety of the staff during the operation and maintenance of photovoltaic modules.
[0048] The rooftop photovoltaic module maintenance access provides a safe and stable access, solving the problem of workers slipping and falling on the wet and slippery surface of the corrugated steel roof during the cleaning, inspection and maintenance of photovoltaic modules. It also provides a stable operating platform and a device for the standardized management of cables to prevent safety accidents caused by tripping over tools, equipment or cables.
[0049] The following is a detailed description of the structure of the maintenance channel for rooftop photovoltaic modules:
[0050] In the optional solution provided by this utility model embodiment, four anti-slip plates are provided. The four anti-slip plates are connected end to end, and two adjacent anti-slip plates are vertically connected to form an area for accommodating photovoltaic modules.
[0051] Specifically, the anti-slip plate is arranged in a ring around the photovoltaic module; correspondingly, the mounting bracket 2 is also arranged in a ring around the photovoltaic module. Furthermore, the anti-slip plate can be parallel to the roof surface for easy installation; of course, the anti-slip plate forming a certain angle with the roof surface should also be within the protection scope of this utility model embodiment.
[0052] Anti-slip plates are installed around the photovoltaic modules, allowing staff to clean, inspect, and repair the modules from different directions, thus improving convenience.
[0053] In the optional solution provided by this utility model embodiment, the anti-slip plate is set as a steel grating plate 1, which has N rows and M columns of holes, and the holes form a water guiding structure.
[0054] Specifically, the width of the steel grating 1 is set to 400mm. The steel grating 1 has multiple regularly arranged holes, allowing water on its upper surface to drain away, preventing it from becoming slippery. Furthermore, the holes divide the upper surface of the steel grating 1 into multiple areas, increasing its roughness. Workers can directly insert tools into the holes. The support member 3 is rectangular, with its length along the width of the steel grating 1, preventing it from clogging the holes and affecting water drainage.
[0055] The anti-slip plate is made of steel grating 1, which has a simple structure and can use its holes to guide water on its upper surface and improve the roughness of the upper surface.
[0056] In the optional solutions provided by the embodiments of this utility model, see Figure 1The support member 3 is connected to the steel grating 1 through the first connector 4; along the width direction of the steel grating 1, the first connector 4 is located in the middle of the steel grating 1.
[0057] Specifically, the first connector 4 is located in the middle of the steel grating 1, so that the steel grating 1 is stably installed on the support 3.
[0058] The first connector 4 connects the support 3 to the steel grating 1.
[0059] In the optional solutions provided by the embodiments of this utility model, see Figure 5 The first connecting member 4 includes a connecting section 41 and two snap-fit sections 42. The two ends of the connecting section 41 are respectively connected to the two snap-fit sections 42. The connecting section 41 is connected to the support member 3 by fasteners. The two snap-fit sections 42 are snap-fitted to the steel grating 1.
[0060] Specifically, a first connector 4 is formed by bending a sheet metal piece, which has a connecting section 41 and two snap-fit sections 42. Fasteners include bolts and nuts, with the bolts passing through the connecting section 41 and the support member 3 in sequence before being connected to the nuts.
[0061] The first connector 4 is connected to the support member 3 through the connecting section 41; and is connected to the steel grating 1 through the snap-fit section 42.
[0062] In the optional solution provided by this utility model embodiment, the steel grating 1 has N rows and M columns of grating bars, and multiple grating bars form N rows and M columns of holes; the snap-fit section 42 snaps into the corresponding grating bar.
[0063] Specifically, see Figure 5 The first connector 4 is bent to form a snap-fit section 42 with a snap-fit cavity 421. Further, the snap-fit section 42 includes a first section 422, a second section 423, and a third section 424. The two ends of the second section 423 are connected at an angle to the first section 422 and the third section 424, respectively, and the first section 422 and the third section 424 are located on the same side of the second section 423. The first section 422, the second section 423, and the third section 424 form the snap-fit cavity 421, into which the grid bars snap. During installation, the steel grating 1 is first placed above the support member 3, and then the first connector 4 is placed above the steel grating 1. The first connector 4 is pressed down so that the snap-fit cavities 421 of the two snap-fit sections 42 snap with the two corresponding grid bars of the steel grating 1, and the connecting section 41 is opposite to the support member 3. Finally, bolts are passed through the connecting section 41 and the support member 3 in sequence and then connected to the nuts. Furthermore, the support member 3 is set as a U-shaped square steel, and the bottom wall of the U-shaped square steel is provided with a second mounting hole, which is engaged with a bolt.
[0064] The snap-fit section 42 snaps into the grid strip, thereby connecting the first connector 4 to the steel grating 1.
[0065] As another implementation, the upper surface of the anti-slip plate is provided with multiple grooves, which form a water-guiding structure.
[0066] Specifically, multiple grooves are spaced apart along the length of the anti-slip plate; or, multiple grooves are spaced apart along the width of the anti-slip plate. In this embodiment, the anti-slip plate is installed on the support member 3 by using bolts to sequentially pass through the anti-slip plate and the support member 3 and then connect them with nuts.
[0067] The grooves effectively guide water from the surface of the anti-slip plate to both sides and enhance the roughness of the surface; the structure is simple and easy to manufacture.
[0068] In the optional solution provided by this utility model embodiment, a second connector is installed at both ends of the support member 3, and the second connector is used to connect with the roof.
[0069] Specifically, the second connector is located at both ends of the support 3 to prevent the second connector from affecting the first connector 4.
[0070] The second connector has two parts, and both are connected to the support 3 and the roof respectively, which enhances the connection strength between the support 3 and the roof and improves the stability of the operation and maintenance channel.
[0071] In the optional solution provided by this utility model embodiment, the second connecting member includes a clamp 51 and a U-shaped connecting member 52.
[0072] Specifically, see Figure 2 When the steel grating 1 is perpendicular to the crest of the corrugated steel sheet, clamp 51 is used to clamp the crest of the corrugated steel sheet, see [reference]. Figure 3 When the steel grating 1 is parallel to the crest of the color steel tile, the U-shaped connector 52 is fixed to the color steel tile using self-tapping screws. The clamp 51 or the U-shaped connector 52 is connected to the support 3 by bolts.
[0073] The clamp 51 and the U-shaped connector 52 correspond to different positions on the roof.
[0074] In the optional solution provided by this utility model embodiment, the roof photovoltaic module operation and maintenance channel also includes a grounding component 6. The grounding component 6 is rectangular, and the length direction of the grounding component 6 and the length direction of the anti-slip plate are arranged side by side. Along the width direction of the anti-slip plate, the mounting frame 2 is located between the anti-slip plate and the grounding component 6, and the grounding component 6 is installed on the support component 3.
[0075] Specifically, grounding component 6 is set as grounding flat steel.
[0076] Grounding component 6 is used to ground the photovoltaic modules, further improving the safety of photovoltaic system operation and maintenance personnel.
[0077] In the optional solution provided by this utility model embodiment, the support member 3 is set as a U-shaped square steel, and the grounding member 6 is welded to the U-shaped square steel.
[0078] Specifically, the open end of the U-shaped square steel faces the grounding component 6, and the closed end faces the roof.
[0079] The grounding flat steel is welded and fixed to the support 3 to enhance the connection strength between the two.
[0080] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0081] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
