DETAILED DESCRIPTION

[0039] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0040] First, the nouns in the embodiments of the present application are explained:

[0041] Photovoltaic modules: PV modules are the core component of solar power generation systems, converting sunlight directly into electricity. They typically consist of multiple photovoltaic cells (also known as solar cells) made of semiconductor materials such as silicon. PV modules can be categorized by their structure and technology, including monocrystalline silicon, polycrystalline silicon, and thin-film modules.

[0042] Photovoltaic panel supports: PV panel supports are structural devices used to mount and secure solar photovoltaic panels. Their primary function is to ensure that the panels are exposed to sunlight at the optimal angle and position, thereby maximizing solar energy collection efficiency. There are various types of PV panel supports, including ground-mounted, roof-mounted, adjustable-angle, and fixed-angle supports. PV panel supports are typically made of aluminum alloy or stainless steel.

[0043] Photovoltaic modules (or solar panels) are the core components of photovoltaic power generation systems. Their primary function is to convert solar energy into electricity. With the continuous advancement of photovoltaic technology, the efficiency and lifespan of photovoltaic modules are also constantly improving. However, due to the influence of the natural environment and the aging of the modules, photovoltaic modules may experience performance degradation or failure after long-term use, necessitating replacement.

[0044] In view of the problem in the prior art that, due to the high installation height of photovoltaic modules, workers need to stand on scaffolding or insulating ladders to replace them, and the steps in the module replacement process are time-consuming and laborious. At the same time, workers are prone to stepping on the photovoltaic modules during the replacement process, causing damage to the photovoltaic bracket. The technical concept of this application is:

[0045] A ladder is designed, wherein at least two hooks are provided at one end of the ladder, and at least two supporting structures are provided at the other end of the ladder. Since the photovoltaic module bracket is set at an angle, an upper supporting frame and a lower supporting frame with a certain height are installed on the photovoltaic module bracket. At least the hook at one end of the ladder is hung on the upper supporting frame, and at least two supporting structures at the other end are placed on the lower supporting frame, so that the ladder is fixed on the upper supporting frame and the lower supporting frame. At the same time, the upper supporting frame and the lower supporting frame support the ladder to be suspended in the air.

[0046] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0047] Example 1

[0048] Figure 1 Schematic diagram of the photovoltaic module replacement ladder provided in the embodiment of the present application Figure 1 ,like Figure 1 As shown, the ladder comprises a ladder frame 100, with at least two hooks 200 disposed at one end of the ladder frame 100 and at least two support structures 300 disposed at the other end of the ladder frame 100. The ladder frame 100 comprises two longitudinal beams, and a plurality of cross beams connect the two longitudinal beams. In this embodiment of the present application, the ladder frame can be made of stainless steel.

[0049] like Figure 1 As shown, the ladder can be provided with two hooks 200, the two hooks 200 are respectively provided on the longitudinal beams of the ladder frame 100, and the support structure 300 can be two support plates, which are also provided on the longitudinal beams of the ladder frame 100. It should be noted that the hooks 200 and the support structure 300 can also be provided on the crossbeams between the longitudinal beams of the ladder frame 100, and the support plates are not limited to Figure 1 The rectangle shown can also be a circle, a triangle, a polygon, etc. The support structure 300 is not limited to Figure 1 The support sheet shown can also be a support block, a support column, etc.

[0050] Figure 2 The ladder installation diagram provided in the embodiment of the present application is as follows: Figure 2 As shown, a first support frame 600 and a second support frame 700 are fixed on the photovoltaic module support 500, and the first support frame 600 is located above the second support frame 700;

[0051] At least two hooks 200 hook the first support frame 600 , and at least two support structures 300 abut against the second support frame 700 to fix the ladder between the first support frame 600 and the second support frame 700 .

[0052] like Figure 2 As shown, a transverse tubular structure may be provided at the top of the first support frame 600 to facilitate the hook 200 to hook the tubular structure. The tubular structure at the top of the first support frame 600 may be a rectangular tube, a round tube, or the like.

[0053] like Figure 2 As shown, the top of the second support frame 700 can be a Y-shaped structure, so that the support piece is stuck in the Y-shaped structure at the top of the second support member to keep the ladder stable. Figure 2 As shown in FIG, the structures are parallel to each other, thereby clamping the vertical support piece.

[0054] It should be noted that the first support frame 600 and the second support frame 700 of the present application are not limited to Figure 2In the structure shown, the first support frame 600 and the second support frame 700 can be fixed to the photovoltaic module support 500 by welding, bolt connection, etc.

[0055] like Figure 1 、 Figure 2 As shown, a bending structure 800 is provided at the end of the ladder frame 100, and each bending structure 800 is connected to at least one supporting structure 300. Figure 1 、 Figure 2 In the embodiment, each bending structure 800 is connected to a supporting structure 300 .

[0056] The bending direction of the bending structure 800 is opposite to that of the hook 200. By setting the bending structure 800, when the ladder is tilted and hung on the photovoltaic module bracket 500, the support plate at the end of the ladder frame 100 can be in a horizontal position, which facilitates the support plate to be inserted into the second support frame 700, thereby achieving a stable connection between the support plate and the second support frame 700.

[0057] like Figure 2 As shown, by arranging the first support frame 600 and the second support frame 700 on the photovoltaic component support 500, when the ladder provided in the embodiment of the present application is fixed between the first support frame 600 and the second support frame 700 in the above manner, the ladder can be suspended above the photovoltaic component support 500, and the staff will not step on the photovoltaic components below when replacing the photovoltaic components on the ladder, which can prevent damage to the photovoltaic components; and by installing the first support frame 600 and the second support frame 700, the ladder can be conveniently fixed by the hook 200 and the support structure 300, and the ladder-building process is convenient and quick.

[0058] like Figure 1 As shown, an abutting structure 400 is provided at the connection between the hook 200 and the first ladder frame 110 . The abutting structure 400 is configured such that when the hook 200 hooks the first support frame 600 , the abutting structure 400 abuts against the first support frame 600 .

[0059] like Figure 2 As shown, when the ladder is placed above the photovoltaic component support 500, when the hook 200 hooks the first support frame 600, the abutment structure 400 below the hook 200 can just abut the first support frame 600, cooperating with the hook 200 to clamp the first support frame 600, thereby improving the firmness of the ladder installation.

[0060] Example 2

[0061] Figure 3 Schematic diagram of the photovoltaic module replacement ladder provided in the embodiment of the present application Figure 2 ,like Figure 3As shown, the ladder frame 100 includes a first ladder frame 110 and a second ladder frame 120. The rear end of the first ladder frame 110 is rotatably connected to the front end of the second ladder frame 120. The front end of the first ladder frame 110 is provided with at least two hooks 200, and the rear end of the second ladder frame 120 is provided with at least two support structures 300.

[0062] like Figure 3 As shown, the first ladder frame 110 and the second ladder frame 120 are rotatably connected via a connecting structure 900 . The connecting structure 900 may be a rivet, a bolt, or a hinge pin to achieve the hinge connection between the first ladder frame 110 and the second ladder frame 120 .

[0063] By designing that the rear end of the first ladder frame 110 and the front end of the second ladder frame 120 are rotatably connected, the first ladder frame 110 can be folded and stored toward the second ladder frame 120 for easy transportation.

[0064] like Figure 3 As shown, at least two fixing structures 1000 are provided on the second ladder frame 120. The fixing structures 1000 are configured to rotate the first ladder frame 110 toward the second ladder frame 120 so that the hooks 200 hook onto the fixing structures 1000. The number of fixing structures 1000 matches the number of hooks 200, and the fixing structures 1000 are symmetrically mounted on the second ladder frame 120 corresponding to the positions of the hooks 200.

[0065] Specifically, such as Figure 3 As shown, the fixing structure 1000 can be a fixing column. When the first ladder frame 110 is folded toward the second ladder frame 120, the hook 200 can hook onto the column of the fixing column. Based on the design of folding the first ladder frame 110 toward the second ladder frame 120 for storage, the fixing structure 1000 can be designed to secure the first ladder frame 110, preventing it from loosening during transportation and facilitating transportation.

[0066] In this embodiment, the fixing post can be a magnetic column. Specifically, the fixing post can be made of a magnetic material, or a magnetic component can be fixed to the fixing post. If the fixing post is magnetic, the hook 200 can be made of iron. Therefore, after the first ladder 110 is folded toward the second ladder 120, the hook 200 not only hooks onto the fixing post, but the magnetism of the fixing post can also attract the iron hook 200, further preventing the first ladder 110 from loosening.

[0067] The fixing structure 1000 may also be a locking structure, and when the first ladder frame 110 is folded toward the second ladder frame 120 , the hook 200 is locked by the locking structure.

[0068] In this embodiment, the fixing structure 1000 can also be a bolt. The bolts are symmetrically arranged on the two longitudinal beams of the second ladder frame 120. After the first ladder frame 110 is folded toward the second ladder frame 120, the hook 200 can hook the column of the bolt to fix the first ladder frame 110.

[0069] Example 3

[0070] Figure 4 Schematic diagram of the photovoltaic module replacement ladder provided in the embodiment of the present application Figure 3 ,like Figure 4 As shown, a protruding abutting structure 400 is provided at the connection between the hook 200 and the ladder frame 100, so that when the hook 200 hooks the first support frame 600, the protruding abutting structure 400 and the hook 200 jointly clamp the first support frame 600. The protruding abutting structure 400 can play a better clamping role than a shorter abutting structure 400.

[0071] Example 4

[0072] Figure 5 Schematic diagram of the photovoltaic module replacement ladder provided in the embodiment of the present application Figure 4 ,like Figure 5 As shown, the two support pieces are connected by a bending structure 800. By connecting the two support pieces by the bending structure 800, a clamping space can be formed between the two support pieces. When installing the ladder, the clamping space can be used to clamp the second support frame 700, thereby improving the stability of the ladder installation.

[0073] In addition, the two supporting plates are connected, which makes it convenient for workers to climb up the ladder by stepping on the two supporting plates.

[0074] Finally, it should be noted that those skilled in the art will readily conceive of other embodiments of the present invention after considering the specification and practicing the invention disclosed herein. This invention is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein.
