Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation system technology, specifically a temporary passage for the maintenance of photovoltaic module arrays, which facilitates the inspection and replacement of photovoltaic modules. Background Technology

[0002] Photovoltaic module arrays are typically installed using a flat-lay method, which involves pre-laying a continuous guide rail on a roof or other suitable surface. Figure 1 Photovoltaic modules are fixed to guide rails using clamps and bolts to form a tightly packed array. However, the structural strength of the photovoltaic modules themselves is insufficient to withstand maintenance personnel walking directly on their surface. To meet the needs of inspection and replacement, existing technology requires the installation of fixed maintenance channels between photovoltaic arrays, allowing direct maintenance of photovoltaic modules near the channels; however, for modules far from the fixed maintenance channels, maintenance personnel still need to remove adjacent modules to access the target location.

[0003] The drawbacks of this approach are that fixed maintenance channels occupy space for photovoltaic module installation; the more channels there are, the less photovoltaic modules can be installed, leading to a decrease in system power generation. Even with fixed maintenance channels, modules far from the channels still require the removal of adjacent components, increasing maintenance time, labor costs, and the risk of module damage. Therefore, there is an urgent need for a photovoltaic array maintenance solution that can both reduce the need for fixed maintenance channels to improve power generation efficiency and avoid the need for module removal. Summary of the Invention

[0004] The purpose of this invention is to provide a temporary maintenance channel for photovoltaic (PV) module arrays. During PV module installation, a temporary maintenance channel support is simultaneously installed on the PV mounting rail. When PV modules need repair or replacement, a temporary maintenance channel is erected above the PV panels using the temporary maintenance channel support, extending to the PV module requiring maintenance. This solution reduces the need for fixed maintenance channels, expands the PV module installation area, and eliminates the need to remove any PV modules during repair or replacement.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A temporary maintenance channel for a photovoltaic module array includes:

[0007] The temporary maintenance access support includes a load-bearing base plate, limiting structures on both sides of the load-bearing base plate, and fastening bolt holes penetrating the load-bearing base plate.

[0008] A temporary maintenance channel panel includes a walkway and support legs fixed below the walkway; wherein, the temporary maintenance channel support is fixed to the photovoltaic module mounting rail through the fastening bolt holes, the support legs are inserted into the limiting structure to form a detachable connection, and multiple temporary maintenance channel panels are sequentially mounted on the support to form a temporary maintenance channel extending from the fixed maintenance channel to the top of the target photovoltaic module.

[0009] Furthermore, the load-bearing base plate is sized to match the width of the photovoltaic module mounting rail, and its bottom surface is fixedly connected to the mounting rail by fastening bolts; the limiting structure is a symmetrically arranged U-shaped groove or buckle structure, used to constrain the lateral displacement of the support leg.

[0010] Furthermore, the temporary maintenance channel support is installed in the gap between the pressure block and the mounting guide rail; the fastening bolt hole shares the same hole position as the mounting bolt of the pressure block, and the support is fastened by adding bolts.

[0011] Furthermore, the end of the support leg is wedge-shaped to enhance the stability of the fit with the limiting structure; the walkways of adjacent temporary maintenance passage panels are connected by overlapping or hinged joints to form a continuous passage.

[0012] Furthermore, the temporary maintenance access board is installed along the shortest distance between the photovoltaic modules to be maintained in the photovoltaic module array; the width of the walkway is not less than the safe working width for maintenance personnel, and the surface is provided with anti-slip texture.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] By combining temporary maintenance channel supports and temporary maintenance channel panels, temporary channels can be erected on the photovoltaic module installation rails as needed, eliminating the need to pre-set a large number of fixed maintenance channels. The freed-up installation space can increase the density of photovoltaic modules, maximize the use of roof or site area, and directly improve the power generation efficiency of the photovoltaic system.

[0015] When photovoltaic modules need to be inspected or replaced near non-fixed maintenance access routes, a temporary access route can be directly erected above the photovoltaic module array by interlocking the support legs of the temporary maintenance access plate with the limiting structure of the temporary maintenance access support. Maintenance personnel can access the target location without removing any photovoltaic modules, significantly reducing the time and labor costs of disassembling and reinstalling modules, while avoiding the risk of module damage caused by frequent disassembly.

[0016] The temporary maintenance access support is installed using the remaining space between the module clamping block and the continuous guide rail, and is secured with nuts by adding nuts to the original bolt holes of the clamping block. This design does not require changes to the original installation method of the photovoltaic modules, ensuring structural stability while simplifying the deployment process of the temporary access, and is suitable for rapid retrofitting of various types of flat-lay photovoltaic power plants.

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1 The photovoltaic module array adopts a flat installation method. First, a long guide rail 6 is installed on the roof or other site. Then, the photovoltaic modules 300 are fixed to the frame of the photovoltaic module one by one using clamping blocks 8 and bolts 9 to form a tightly arranged array. Since the photovoltaic modules 300 themselves are not strong enough to withstand direct foot traffic, inspection and replacement work needs to be carried out through a temporary maintenance passage.

[0027] Please see Figure 2 and Figure 4The temporary maintenance access support 100 consists of a load-bearing base plate 1, two side limiting structures 2, and fastening bolt holes 3. The dimensions of the load-bearing base plate 1 are adapted to the width of the full-length guide rail 6, and its bottom surface is fixedly connected to the guide rail 6 through the fastening bolt holes 3. During installation, the temporary maintenance access support 100 is placed in the remaining space between the pressure block 8 and the guide rail 6, and the support 100 is fastened by adding nuts using the original holes of the pressure block bolts 9. This installation method does not require modification of the original structure of the photovoltaic module 300 and does not interfere with the pressure block 8.

[0028] Please see Figure 3 and Figure 5 The temporary maintenance access board 200 is made of lightweight material and includes a walkway 4 and support legs 5. The support legs 5 are vertically fixed below the walkway 4, and the ends are designed in a wedge shape to enhance the stability of the fit with the limiting structure 2. During installation, the support legs 5 are inserted into the limiting structure 2 of the temporary maintenance access support 100, and the lateral displacement is restrained by the U-shaped groove or the snap-fit ​​structure to form a detachable connection.

[0029] Please see Figure 5 and Figure 7 When maintenance is required on photovoltaic modules 400 located away from the fixed maintenance channel 7, multiple temporary maintenance channel panels 200 are sequentially erected on temporary maintenance channel supports 100, starting from the beginning of the fixed maintenance channel 7. Adjacent channels 4 are connected by overlapping or hinged joints to form a continuous temporary maintenance channel 500. The temporary maintenance channel 500 extends along the shortest path of the photovoltaic modules 400 to be maintained, covering the non-load-bearing area above the photovoltaic module array. The width of the channel 4 meets the safety requirements of maintenance personnel, and the surface is equipped with anti-slip textures to ensure operational safety.

[0030] Please see Figure 6 and 7 After maintenance personnel reach the target photovoltaic module 400 through the temporary maintenance channel 500, they can directly perform inspection or replacement work without removing any adjacent modules. After the work is completed, the temporary maintenance channel panel 200 can be quickly disassembled, restoring the photovoltaic array to its complete state. With the use of the temporary maintenance channel, the number of fixed maintenance channels 7 in the photovoltaic module array is significantly reduced, and the freed-up installation space can be used to increase the laying density of photovoltaic modules 300, thereby increasing the system's power generation. Comparing the array layout before and after use, it is clear that the temporary channel 500 is only erected when needed and does not affect the original module arrangement.

[0031] In summary, this utility model achieves efficient maintenance of photovoltaic module arrays through the modular design of temporary maintenance channel support 100 and temporary maintenance channel plate 200, while improving power generation efficiency and construction convenience during maintenance.
