Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a maintenance support that is easy to operate. Background Technology

[0002] With the expansion of photovoltaic power plant scale and the increase in operation and maintenance costs, improving operation and maintenance efficiency and reducing operation and maintenance costs have become important directions for the development of mountain photovoltaic power plants. During operation and maintenance, the replacement of photovoltaic modules and the repair of support structures are common needs. However, due to the complexity of mountainous terrain, traditional maintenance methods are often inefficient and pose safety hazards.

[0003] Mountain photovoltaic (PV) power stations are typically built on complex and varied mountainous terrain, which presents numerous challenges to their construction and operation. First, the undulating terrain and varying slopes result in inconsistent installation heights for PV modules, significantly complicating maintenance work. Second, the complex geological conditions of mountains, with their unstable soil and uneven rock distribution, place higher demands on the stability and load-bearing capacity of the maintenance support structures. Furthermore, the variable mountain climate, characterized by strong winds, heavy rainfall, and large temperature differences, imposes special requirements on the materials, structure, and corrosion resistance of the maintenance support structures. The inconsistent installation heights of PV modules due to the undulating terrain and varying slopes further complicate maintenance work.

[0004] However, existing maintenance supports for photovoltaic power stations in mountainous terrain are mostly ladders. Due to structural limitations, the bottom of the ladder needs to be supported by the ground. Mountainous terrain has a significant impact on the stability of the ladder. In addition, ladders cannot adapt to photovoltaic modules with different installation heights. The overall volume of the ladder is large, making it inconvenient to transport in mountainous terrain and resulting in poor performance. Based on this, this utility model designs an easy-to-operate maintenance support to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an easy-to-operate maintenance bracket to solve the problems mentioned above, such as the inability of ordinary maintenance ladders to install photovoltaic modules of different heights in mountainous terrain, and the difficulty in transporting ordinary maintenance ladders.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An easy-to-operate maintenance bracket for photovoltaic module maintenance includes a support column. An upper crossbeam and a lower crossbeam are detachably connected to the upper and lower ends of the support column, respectively. A diagonal brace is movably connected to the other end of the upper crossbeam, and the other end of the lower crossbeam is movably connected to the other end of the diagonal brace. The support column and the diagonal brace are movably connected at their middle sections. A triangular support is formed between the upper and lower crossbeams and the support column. The upper and lower crossbeams form support end faces. A first fastener is welded to one side of the support column, and a second fastener is provided on the lower crossbeam. The first and second fasteners are used to engage the photovoltaic module.

[0008] As a further embodiment of this utility model: the lower crossbeam is sleeved with the second fastener, the second fastener is fixed to the lower crossbeam by bolts, and the second fastener can move laterally on the lower crossbeam to adapt to the different angles of the connection between the photovoltaic module and the lower crossbeam.

[0009] As a further embodiment of this utility model: a telescopic cavity is provided at one end of the support column near the lower crossbeam, and a telescopic rod is installed in the telescopic cavity. The telescopic rod is used to extend the support height of the support column, and a fixing bolt is threaded to one end of the support column near the lower crossbeam. The fixing bolt is used to fix the telescopic rod.

[0010] As a further embodiment of this utility model: the snap-fit ​​ends of the first and second snap-fit ​​components are both U-shaped.

[0011] As a further embodiment of this utility model, it also includes a maintenance platform, which is placed on the supporting end face of the upper crossbeam and is used for maintenance operations of the photovoltaic module.

[0012] As a further embodiment of this utility model: the maintenance platform is placed on the supporting end face of the lower crossbeam, and the maintenance platform is used for the maintenance operation of the photovoltaic module.

[0013] As a further embodiment of this utility model: a placement groove is provided on the support end face of both the upper and lower crossbeams, and the maintenance platform is matched and snapped into the placement groove, which is used to limit the position of the maintenance platform.

[0014] As a further embodiment of this utility model: the maintenance platform is an anti-slip foot pedal, and multiple sets of anti-slip strips are provided on the anti-slip foot pedal.

[0015] As a further embodiment of this utility model: the connecting ends of the upper and lower crossbeams and the supporting column are provided with locking pins, and the locking pins are detachably connected to the upper and lower ends of the supporting column.

[0016] As a further embodiment of this utility model: the connecting ends of the upper and lower crossbeams and the supporting column are provided with bolts, and the bolts are detachably threaded to the upper and lower ends of the supporting column.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, the upper and lower crossbeams, which are detachably connected at both ends of the supporting column, are placed horizontally. The upper and lower crossbeams and the supporting column are all movably connected to the diagonal braces. The upper and lower crossbeams, the supporting column, and the diagonal braces form two triangular structures. Through the stable support of the triangles, the upper and lower crossbeams are placed horizontally and form stable support end faces. The support end faces of the upper and lower layers support the placement of maintenance equipment at different heights, allowing maintenance personnel to stand at the corresponding maintenance height and perform convenient and quick maintenance on the photovoltaic panels at the top. The supporting column is detachably connected to the upper and lower crossbeams. When transporting the equipment on the complex terrain of the mountain photovoltaic power station, the upper and lower crossbeams are separated from the supporting column, and the upper and lower crossbeams and the diagonal braces are folded over the supporting column, reducing the overall volume of the device and facilitating transportation in complex mountainous environments.

[0019] 2. In this utility model, the device uses the Y-shaped structure of the photovoltaic bracket for snap-fit ​​fixation. During installation, the device does not require a base for support and does not rely on the foundation of the mountain. Therefore, the complex geological conditions of the mountain, poor soil stability, uneven rock distribution, etc. will not affect the maintenance operation of the device. The device uses the photovoltaic bracket as the support point, and the height of the support end face formed by the device matches the height of the photovoltaic panel, which is suitable for the maintenance of photovoltaic panels of various heights in mountain photovoltaic power stations.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "comprising" and similar expressions used herein mean that the element or object preceding the word covers the element or object listed following the word and its equivalents, but does not exclude other elements or objects.

[0029] Example:

[0030] Please see Figures 1-7 In this embodiment of the utility model, an easy-to-operate maintenance bracket is applied to the maintenance of photovoltaic modules. It includes a support column 1, with an upper crossbeam 2 and a lower crossbeam 3 detachably connected to the upper and lower ends of the support column 1, respectively. The other end of the upper crossbeam 2 is movably connected to a diagonal brace 4, and the other end of the lower crossbeam 3 is movably connected to the other end of the diagonal brace 4. The support column 1 and the diagonal brace 4 are movably connected at the middle. The upper crossbeam 2 and the lower crossbeam 3 form a triangular support with the support column 1. The upper crossbeam 2 and the lower crossbeam 3 are used to form a support end face. A first fastener 5 is welded to one side of the support column 1, and a second fastener 6 is provided on the lower crossbeam 3. The first fastener 5 and the second fastener 6 are used to fasten the photovoltaic modules.

[0031] Specifically, such as Figures 5-7As shown, the photovoltaic module includes a photovoltaic support frame 9 and a photovoltaic panel 10. The photovoltaic support frame 9 supports the photovoltaic panel 10. The bottom end of the photovoltaic support frame 9 is fixedly connected to the base of the mountain. The upper end of the photovoltaic support frame 9 supports the inclined photovoltaic panel 10. The photovoltaic support frame 9 is Y-shaped to provide inclined and stable support for the photovoltaic panel 10. The first fastener 5 on the support column 1 is matched and fastened to the vertical part of the frame of the photovoltaic support frame 9. The bottom end of the support column 1 contacts the bifurcation of the photovoltaic support frame 9. The second fastener 6 on the lower crossbeam 3 is fastened to the inclined part of the photovoltaic support frame 9. The device is supported by three points: the first fastener 5, the second fastener 6, and the bottom end of the support column 1. The entire structure is stably connected to the photovoltaic bracket 9. The upper and lower crossbeams 2 and 3, detachably connected at both ends of the support column 1, are horizontally positioned. The upper and lower crossbeams 2 and 3, along with the support column 1, are all movably connected to the diagonal braces 4. These structures form two triangular structures, providing stable support for the upper and lower crossbeams 2 and 3, ensuring their horizontal placement and stable support surfaces. These two layers of support surfaces support maintenance equipment at different heights, allowing maintenance personnel to stand at the corresponding maintenance height for convenient and quick maintenance of the upper photovoltaic panels 10. The support column 1, along with the upper and lower crossbeams 2 and 3, are detachably connected at both ends. All crossbeams 3 are detachable. When transporting them on complex terrain in mountainous photovoltaic power stations, the upper crossbeam 2 and lower crossbeam 3 are separated from the supporting column 1, allowing the upper crossbeam 2, lower crossbeam 3, and diagonal brace 4 to overlap and fold with the supporting column 1, reducing the overall volume of the device and facilitating transport in complex mountainous environments. The device has a simple overall structure, is lightweight, and easy to transport. It utilizes the Y-shaped structure of the photovoltaic bracket 9 for snap-fit ​​fixing. During installation, the device does not require a base support and is not dependent on the mountain's foundation. Therefore, complex geological conditions, poor soil stability, and uneven rock distribution in mountainous areas will not affect the maintenance operation of the device. Traditional maintenance ladders have a limited height... Due to inherent limitations and structural constraints on the support height, the existing system cannot fully accommodate the various heights of the photovoltaic support bracket 9 in mountainous photovoltaic power stations. The height of the operator relative to the photovoltaic panel 10 cannot reach the ideal level, hindering convenient maintenance. This new device uses the photovoltaic support bracket 9 as a support point, ensuring that the height of the support end face matches the height of the photovoltaic panel 10. It is suitable for maintaining photovoltaic panels 10 at various heights in mountainous photovoltaic power stations. The device is easy and quick to install, provides stable support connections, and has a compact folding size, making it easy to transport in mountainous areas. It is also independent of mountainous geological conditions, convenient to use, reduces the difficulty of maintaining photovoltaic panels 10 in mountainous photovoltaic power stations, and saves on operation and maintenance costs.

[0032] Preferred, such as Figure 3As shown, the lower crossbeam 3 is sleeved with the second fastener 6, which is fixed to the lower crossbeam 3 by bolts. The second fastener 6 can move laterally on the lower crossbeam 3 to accommodate different angles at the connection between the photovoltaic module and the lower crossbeam 3. The second fastener 6 is sleeved on the lower crossbeam 3 and fixed with bolts after adjustment, allowing it to move laterally on the lower crossbeam 3. This adjusts the snap-fit ​​point between the second fastener 6 and the photovoltaic bracket 9. When the inclined and vertical parts of the photovoltaic bracket 9 have different angles, adjusting the position of the second fastener 6 adapts to photovoltaic brackets 9 with different angles between the inclined and vertical parts, thus having a wide range of applications.

[0033] Preferred, such as Figure 2 As shown, a telescopic cavity is provided at one end of the support column 1 near the lower crossbeam 3, and a telescopic rod 7 is installed inside the telescopic cavity. The telescopic rod 7 is used to extend the support height of the support column 1. A fixing bolt is threaded to one end of the support column 1 near the lower crossbeam 3, and the fixing bolt is used to fix the telescopic rod 7. An adjustable telescopic rod 7 is installed in the telescopic cavity of the lower crossbeam 3. After telescopic adjustment, the telescopic rod 7 is fixed by the fixing bolt. The telescopic rod 7 extends the overall support length of the support column 1. When facing different photovoltaic brackets 9, the overall height of the upper crossbeam 2 and the lower crossbeam 3 can be adjusted by adjusting the telescopic rod 7 and the overall support length of the support column 1. When facing different photovoltaic brackets 9, the upper crossbeam 2 and the lower crossbeam 3 can reach the optimal height for maintaining the photovoltaic panels 10, thus broadening the applicability.

[0034] Preferred, such as Figure 2 As shown, the snap-fit ​​ends of the first snap-fit ​​member 5 and the second snap-fit ​​member 6 are both U-shaped. The first snap-fit ​​member 5 and the second snap-fit ​​member 6 are snapped into the photovoltaic bracket 9 through their U-shaped snap-fit ​​ends. The width of the snap-fit ​​ends of the first snap-fit ​​member 5 and the second snap-fit ​​member 6 is greater than the width of the photovoltaic bracket 9. The wider snap-fit ​​ends of the first snap-fit ​​member 5 and the second snap-fit ​​member 6 facilitate easy snap-fit ​​with the photovoltaic bracket 9 and simplify operation.

[0035] Preferred, such as Figure 7 As shown, it also includes a maintenance platform 8, which is placed on the support end face of the upper crossbeam 2. The maintenance platform 8 is used for the maintenance of photovoltaic modules. Multiple upper crossbeams 2 on multiple maintenance brackets form multi-point support on the same horizontal plane. The maintenance platform 8 is placed on multiple upper crossbeams 2 on the same horizontal plane, forming a large maintenance surface. The maintenance platform 8 is used for placing maintenance equipment and for maintenance personnel to stand on, thereby enabling the maintenance of the photovoltaic panels 10 at the upper end.

[0036] Preferred, such as Figure 7As shown, the maintenance platform 8 is placed on the support end face of the lower crossbeam 3. The maintenance platform 8 is used for the maintenance of photovoltaic modules. Multiple lower crossbeams 3 on multiple maintenance brackets form multi-point support on the same horizontal plane. The maintenance platform 8 is placed on multiple lower crossbeams 3 on the same horizontal plane, forming a large maintenance surface. The maintenance platform 8 is used for placing maintenance equipment and for maintenance personnel to stand on, thereby enabling the maintenance of the upper photovoltaic panels 10. The multi-tiered maintenance surface allows for maintenance operations at different positions on the tilted photovoltaic panels 10, resulting in good performance.

[0037] Preferred, such as Figure 7 The upper crossbeam 2 and lower crossbeam 3 are both provided with placement grooves on their support end faces. The maintenance platform 8 is matched and snapped into the placement grooves, which are used to limit the movement of the maintenance platform 8. By using the placement grooves on the upper crossbeam 2 and lower crossbeam 3 to snap and limit the movement of the maintenance platform 8, sliding of the maintenance platform 8 is prevented, ensuring the safety of maintenance personnel.

[0038] Preferably (not shown in the figure), the maintenance platform 8 is a non-slip foot pedal, and the non-slip foot pedal is equipped with multiple sets of anti-slip strips. The multiple sets of anti-slip strips on the non-slip foot pedal increase friction, making it more stable for maintenance personnel to stand, and improving the safety performance of the device.

[0039] Preferably (not shown in the figure), the connecting ends of the upper crossbeam 2 and the lower crossbeam 3 to the support column 1 are provided with locking pins, which are detachably engaged with the upper and lower ends of the support column 1. The upper crossbeam 2 and the lower crossbeam 3 are connected to the support column 1 by locking pins, and the detachable engagement allows for easy disassembly and reassembly of the upper crossbeam 2 and the lower crossbeam 3 from the support column 1, making it highly operable.

[0040] Preferably (not shown in the figure), bolts pass through the connection ends of the upper crossbeam 2 and lower crossbeam 3 to the supporting column 1, and the bolts are detachably threaded to the upper and lower ends of the supporting column 1.
