[0046] Photovoltaic power stations generate electricity through photovoltaic modules. A photovoltaic power station consists of a photovoltaic module array. As the service time of the photovoltaic modules increases, the failure rate of the photovoltaic modules increases, and regular maintenance work needs to be carried out.

[0047] In the prior art, since the top of the photovoltaic module support is at a relatively high distance from the ground, during the maintenance process, a straight ladder is leaned against one side of the photovoltaic module for maintenance. However, when maintaining photovoltaic modules in mountainous terrains, due to the complex and changeable mountainous terrain, the ground is uneven and has a large slope, resulting in poor stability of the straight ladder placement and making it difficult to ensure the safety of the operators.

[0048] In view of this, the embodiments of the present application provide a maintenance ladder, including: a telescopic component, a connection component, and at least two anti-slip components; the telescopic component includes a first telescopic ladder and a second telescopic ladder, and the first telescopic ladder is hinged to the second telescopic ladder; the connection component is arranged on the second telescopic ladder and is used to connect with the photovoltaic module; each anti-slip component is respectively connected to the first telescopic ladder and the second telescopic ladder and faces away from the connection component. The first telescopic ladder and the second telescopic ladder can be relatively far away or relatively close to each other through the hinge, and the interval between the two can be flexibly adjusted according to the terrain. Moreover, a stable triangular structure is formed between the first telescopic ladder, the second telescopic ladder, and the ground, enhancing the stability of the maintenance ladder. In addition, by connecting with the photovoltaic module through the connection component, the stability of the maintenance ladder is enhanced. Additionally, the anti-slip components are respectively arranged at the bottoms of the first telescopic ladder and the second telescopic ladder and face the ground, thereby increasing the friction force and ensuring the stability of the maintenance ladder during use.

[0049] The following will be combined with Figures 1 to 5 and specific embodiments to elaborate on the present application in detail. Figure 1 It is a schematic structural diagram of the maintenance ladder provided by the embodiments of the present application; Figure 2 It is Figure 1 a schematic structural diagram of the lifting component in Figure 3 It is Figure 1 a schematic structural diagram of the driving component and the handle component in Figure 4 It is a schematic structural diagram of the connecting piece; Figure 5 It is Figure 1 a schematic structural diagram of the connecting piece in

[0051] In specific implementation, the first telescopic ladder 110 is hinged to the second telescopic ladder 120, and the first telescopic ladder 110 and the second telescopic ladder 120 can be relatively far away from or relatively close to each other, so that the inspection ladder can adapt to various terrains and inspection requirements. The first telescopic ladder 110 and the second telescopic ladder 120 can also be unfolded or retracted to adjust the height of the inspection ladder, or the height of the first telescopic ladder 110 or the second telescopic ladder 120 can be adjusted separately according to the terrain adaptability. After use, the first telescopic ladder 110 and the second telescopic ladder 120 are relatively close to each other, and the first telescopic ladder 110 and the second telescopic ladder 120 are retracted, so that the ladder occupies less space when stored, which is convenient for carrying and storing.

[0052] Exemplarily, as Figure 1 and Figure 2 shown, a hinge portion is provided at the top of the first telescopic ladder 110, and the second telescopic ladder 120 also has the same hinge portion at the top. For the convenience of description, the hinge portion at the top of the first telescopic ladder 110 is named the first hinge portion, and the hinge portion at the top of the second telescopic ladder 120 is named the second hinge portion. The first hinge portion is inserted into the second hinge portion. Hinge holes are provided on both the first hinge portion and the second hinge portion. When the first hinge portion is inserted into the second hinge portion, the axes of the hinge holes of the first hinge portion and the axes of the hinge holes of the second hinge portion coincide, and the hinge shaft passes through the hinge holes to connect the first hinge portion and the second hinge portion. Through the hinged manner, it is convenient for the first telescopic ladder 110 and the second telescopic ladder 120 to be relatively far away from or relatively close to each other.

A stable triangular structure is formed between the first telescopic ladder 110, the second telescopic ladder 120 and the ground, which enhances the stability of the maintenance ladder.
