[0032] As shown in the background technology, in the prior art, for some photovoltaic power stations that have been in operation for a long time, affected by the natural environment and production and installation processes, more and more components have problems such as hot spots, hidden cracks, power attenuation, backboard aging, fragmentation, deformation, wind blowing, loosening, etc., which require replacement or re-fixation of photovoltaic components. Since conventional ladders are equipped with multiple footrest beams between two columns, a large placement space is required, and the photovoltaic components installed in groups are arranged compactly, and the gaps between photovoltaic components are small, when conventional ladders cannot be used, maintenance personnel need to step on the photovoltaic components for support. However, the surface of photovoltaic components is smooth and has a slope, and there are safety hazards when maintenance personnel step on photovoltaic components.

[0033] Based on this, the ladder for photovoltaic module maintenance provided by the present application is provided with a ladder vertical rod, a plurality of footrest crossbars and at least one fixing clamp, and footrest crossbars are provided on both sides of the ladder vertical rods, and the footrest crossbars are provided at intervals along the extension direction of the ladder vertical rods. The ladder vertical rods are located in the middle of the footrest crossbars, which reduces the placement space required for the ladder and can adapt to photovoltaic modules with smaller spacing. A pair of fixings are provided to form a fixing clamp, and the fixings are slidably connected to the ladder vertical rods, and each pair of fixings are relatively arranged to jointly clamp the steel beam of the photovoltaic bracket, thereby fixing the ladder and providing a safe working platform for maintenance personnel.

[0034] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0035] Figure 1 A schematic diagram of the structure of a ladder for photovoltaic module maintenance provided in an embodiment of the present application; Figure 2 for Figure 1 Schematic diagram of the structure from another angle.

[0036] Reference Figure 1 and Figure 2 As shown, the ladder for photovoltaic module maintenance provided by the present application includes a ladder vertical rod 100, a plurality of footrest cross bars 200 and at least one fixing clamp 300, and the footrest cross bars 200 are correspondingly arranged on the opposite sides of the ladder vertical rod 100, and the footrest cross bars 200 are arranged at intervals along the extension direction of the ladder vertical rod 100.

[0037] The fixing clamp 300 includes a pair of fixing members 310 , which are slidably connected to the ladder vertical rod 100 , and each pair of fixing members 310 are arranged opposite to each other to jointly clamp the steel beam of the photovoltaic support.

[0038] For example, the width of the ladder vertical rod 100 can be consistent with the gap width of the photovoltaic module, and the length of the ladder vertical rod 100 can be 1.5 times the length of the photovoltaic module. As long as the ladder can be placed between the photovoltaic brackets and it is convenient for maintenance personnel to maintain the photovoltaic module, the present application does not impose too many restrictions on the width and length of the ladder vertical rod 100.

[0039] It should be noted that the footrest crossbar 200 is correspondingly arranged on both sides of the ladder vertical bar 100, that is, the ladder vertical bar 100 is located in the middle of the footrest crossbar 200, which reduces the placement space required for the ladder and can adapt to photovoltaic modules with smaller spacing.

[0040] It can be understood that the footrest crossbar 200 is correspondingly arranged on the two opposite sides of the ladder vertical rod 100, that is, the footrest crossbar 200 is arranged along the ladder vertical rod 100. Figure 2 The X direction indicated by the middle arrow makes the forces on both sides of the ladder vertical rod 100 balanced, thereby improving the stability of the ladder.

[0041] At the same time, the footrest crossbars 200 are located on opposite sides of the ladder vertical rods 100, which is convenient for maintenance personnel to climb and stand. The footrest crossbars 200 are arranged at intervals along the extension direction of the ladder vertical rods 100, that is, the footrest crossbars 200 are arranged along the extension direction of the ladder vertical rods 100. Figure 2 The Y direction interval setting is shown by the arrow in the middle.

[0042] Exemplarily, the size of the footrest crossbar 200 can be 300 mm in length, 40 mm in width, and 20 mm in height, or other sizes, depending on actual needs, and the present application does not impose too many restrictions on this.

[0043] Exemplarily, the spacing between the footrest bars 200 may be 450 mm, and may also be adjusted according to the height of the photovoltaic module. The present application does not impose too many restrictions on the spacing and number of the footrest bars 200.

[0044] Exemplarily, the footrest crossbar 200 may be welded to the ladder vertical bar 100, or may be connected in other ways. The present application does not impose too many restrictions on the connection method between the footrest crossbar 200 and the ladder vertical bar 100.

[0045] Exemplarily, the ladder vertical rod 100 and the footrest horizontal rod 200 can be made of square steel or other materials, and the present application does not impose too many restrictions on this.

[0046] Exemplarily, there may be one or more fixing clips 300 , and the present application does not impose too many restrictions on the number of fixing clips 300 .

[0047] Further, a pair of fixing members 310 are provided to form a fixing clamp 300, and each pair of fixing members 310 is arranged along Figure 2 The Y directions indicated by the middle arrows are arranged relatively to jointly clamp the steel beams of the photovoltaic bracket, thereby fixing the ladder and providing a safe working platform for maintenance personnel.

[0048] Furthermore, the fixing member 310 is slidably connected to the ladder vertical rod 100, and the size of the fixing clamp 300 can be adjusted by sliding the fixing member 310, so that steel beams of different sizes of the photovoltaic bracket can be clamped, thereby improving the applicability of the ladder.

[0049] It is understandable that, compared with conventional ladders in the prior art, a larger placement space is required. When conventional ladders cannot be used, maintenance personnel need to step on photovoltaic modules as support. The ladder used for photovoltaic module maintenance in this embodiment is provided with a ladder vertical rod 100, a plurality of footrest crossbars 200 and at least one fixing clamp 300. The ladder vertical rod 100 is provided with footrest crossbars 200 on both sides opposite to each other. The footrest crossbars 200 are arranged at intervals along the extension direction of the ladder vertical rod 100. The ladder vertical rod 100 is located in the middle of the footrest crossbar 200, which reduces the placement space required for the ladder and can adapt to photovoltaic modules with smaller spacing. By providing a pair of fixing members 310 to form a fixing clamp 300, the fixing member 310 is slidably connected to the ladder vertical rod 100, and each pair of fixing members 310 is relatively arranged to clamp the steel beam of the photovoltaic support together, thereby fixing the ladder and providing a safe working platform for maintenance personnel.

[0050] Figure 3 for Figure 1 Schematic diagram of the structure from another angle.

[0051] In some embodiments, reference Figure 3 As shown, the fixing member 310 includes a first limiting portion 311, a clamping portion 312 and a second limiting portion 313. One end of the first limiting portion 311 is slidably connected to the ladder vertical rod 100, and the other end of the first limiting portion 311 is connected to the second limiting portion 313 through the clamping portion 312. The clamping portion 312 is used to abut against the steel beam.

[0052] It can be understood that the clamping of the steel beam by the fixing clamp 300 is achieved by the clamping portions 312 of each pair of fixing members 310 abutting against the steel beam.

[0053] Furthermore, the first limit portion 311 is slidably connected to the ladder vertical rod 100, that is, the first limit portion 311 can be slidably connected to the ladder vertical rod 100 along the Figure 2 The fixing clip 300 slides in the Y direction as indicated by the middle arrow, thereby adjusting the distance between each pair of fixing members 310, that is, adjusting the size of the fixing clip 300, to adapt to steel beams of different sizes.

[0054] At the same time, the height of the fixing clamp 300 can be changed by sliding the first limiting portion 311, so that the ladder can adapt to steel beams of different heights.

[0055] In some embodiments, reference Figure 3 As shown, the opposite side of the clamping portion 312 of each pair of fixing members 310 is a curved surface 3121 .

[0056] It should be noted that the opposite side of the clamping portion 312 of each pair of fixing members 310 is set as a curved surface 3121, which improves the clamping effect.

[0057] In some embodiments, reference Figure 3As shown, a buffer is provided on the arc surface 3121, and the buffer is used to contact the steel beam.

[0058] It can be understood that by setting the buffer member in contact with the steel beam, the steel beam can be protected, and at the same time the friction between the buffer member and the steel beam is increased, further improving the clamping effect of the fixing clamp 300.

[0059] Exemplarily, the buffer may be a rubber cushion layer or other materials, and the present application does not impose too many restrictions on this.

[0060] In some embodiments, reference Figure 3 As shown, the first limiting portion 311 has a first abutting section 3111 , and the second limiting portion 313 has a second abutting section 3131 . The first abutting section 3111 and the second abutting section 3131 are respectively located at two ends of the arc surface 3121 .

[0061] Specifically, by setting a first abutment section 3111 on the first limiting portion 311 and a second abutment section 3131 on the second limiting portion 313, the first abutment section 3111 and the second abutment section 3131 are respectively located at the two ends of the arc surface 3121, which can stop the steel beam and prevent it from detaching from the clamping portion 312.

[0062] In some embodiments, reference Figure 3 As shown, one end of the second limiting portion 313 of each pair of fixing members 310 is provided with a socket, and the other end is provided with a buckle matching the socket.

[0063] It can be understood that by respectively providing a socket and a buckle at the end of the second limiting member 400 of each pair of fixing members 310, the socket and the buckle are clamped together to prevent the steel beam from detaching from the fixing clamp 300, thereby further improving the reliability of the fixing clamp 300.

[0064] In some embodiments, reference Figure 2 and Figure 3 As shown, a slide groove 110 is provided on the side of the ladder vertical rod 100 facing the steel beam, and the extension direction of the slide groove 110 is consistent with the extension direction of the ladder vertical rod 100. The first limiting portion 311 is inserted in the slide groove 110, and the first limiting portion 311 slides relative to the slide groove 110.

[0065] Specifically, the extending direction of the chute 110 is consistent with the extending direction of the ladder vertical rod 100, that is, the chute 110 extends along the Figure 2 The first limiting portion 311 is arranged in the Y direction as indicated by the middle arrow, so that the first limiting portion 311 can slide relative to the slide groove 110 along the Y direction or the opposite direction of the Y direction, thereby adjusting the height of the first limiting portion 311 .

[0066] In some embodiments, reference Figure 3As shown, at least two limit members 400 are also included. The slide groove 110 has a plurality of threaded holes 111 . The limit members 400 are connected to the threaded holes 111 by threads. The limit members 400 are located below the first limit portion 311 . The limit members 400 are used to abut against the first limit portion 311 .

[0067] Exemplarily, there may be two or more limiting members 400 , and the number of the limiting members 400 is consistent with the number of the fixing members 310 .

[0068] Specifically, the limiting member 400 is disposed below the first limiting portion 311 and abuts against the first limiting portion 311 , so as to stop the first limiting portion 311 , thereby fixing the first limiting portion 311 .

[0069] In some embodiments, reference Figure 3 As shown, the limiting member 400 is a bolt.

[0070] It can be understood that the limiting member 400 is connected to the threaded hole 111 by bolts, which is easy to operate and the connection method is stable and reliable.

[0071] In some embodiments, reference Figure 1 As shown, a rubber sheath 210 is sleeved on the footrest crossbar 200 .

[0072] It should be noted that by sleeve-arranging the rubber sheath 210 on the footrest crossbar 200, it is possible to prevent the footrest crossbar 200 from scratching the photovoltaic module, while improving the safety and comfort of climbing the ladder.

[0073] It should also be noted that the entire ladder can be painted and insulated to further improve safety.

[0074] It can be understood by those skilled in the art that the ladder for photovoltaic module maintenance provided by the present application is provided with a ladder vertical rod 100, a plurality of footrest crossbars 200 and at least one fixing clamp 300, the footrest crossbars 200 are provided on both opposite sides of the ladder vertical rod 100, the footrest crossbars 200 are provided at intervals along the extension direction of the ladder vertical rod 100, and the ladder vertical rod 100 is located in the middle of the footrest crossbar 200, thereby reducing the placement space required for the ladder, and can be adapted to photovoltaic modules with smaller spacing. By providing a pair of fixing members 310 to form a fixing clamp 300, the fixing member 310 is slidably connected to the ladder vertical rod 100, and each pair of fixing members 310 is relatively arranged to jointly clamp the steel beam of the photovoltaic support, thereby fixing the ladder, and providing a safe working platform for maintenance personnel.
