Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic equipment maintenance, and in particular to a bending ladder for photovoltaic modules. Background Art

[0002] A photovoltaic power station is a device that uses the radiation energy of the sun to generate electricity. A photovoltaic power station converts solar energy into electrical energy by absorbing solar radiation through photovoltaic modules. Photovoltaic modules include mounting brackets, photovoltaic panel mounting frames and photovoltaic panels. The photovoltaic panel mounting frame is arranged above the mounting bracket, and the photovoltaic panel is mounted on the photovoltaic panel mounting frame. The mounting bracket supports the photovoltaic panel at a higher position to absorb solar energy. In order to increase the absorption rate, the photovoltaic panel mounting frame and the photovoltaic panel are usually inclined surfaces. Replacement or maintenance of photovoltaic panels is one of the most common tasks in daily operation and maintenance.

[0003] In daily operation and maintenance work, when workers inspect and repair photovoltaic modules, they need to use ladders to climb onto the photovoltaic panels to replace or inspect the photovoltaic panels and other components located above. The existing ladders are vertical. After workers climb to the top of the photovoltaic panels, they need to bring up the ladder again because the photovoltaic panel mounting frame and the photovoltaic panels are inclined surfaces. Then, the ladder is placed against the photovoltaic panel mounting frame located above. The workers can move on the ladder to move to photovoltaic panels at different positions, and the workers can replace or inspect each photovoltaic panel.

[0004] Since the existing ladder needs to be placed against the photovoltaic panel mounting frame, when a worker steps on the ladder, the ladder exerts great pressure on the photovoltaic panel mounting frame, causing the photovoltaic panel mounting frame to deform, which can easily cause damage to the photovoltaic panel and the photovoltaic panel mounting frame.

[0043] A photovoltaic power station is a device that uses the radiation energy of the sun to generate electricity. A photovoltaic power station converts solar energy into electrical energy by absorbing solar radiation through photovoltaic modules. Photovoltaic modules include mounting brackets, photovoltaic panel mounting frames and photovoltaic panels. The photovoltaic panel mounting frame is arranged above the mounting bracket, and the photovoltaic panel is mounted on the photovoltaic panel mounting frame. The mounting bracket supports the photovoltaic panel at a higher position to absorb solar energy. In order to increase the absorption rate, the photovoltaic panel mounting frame and the photovoltaic panel are usually inclined surfaces. Replacement or maintenance of photovoltaic panels is one of the most common tasks in daily operation and maintenance.

[0044] In daily operation and maintenance work, when workers inspect and repair photovoltaic modules, they need to use ladders to climb onto the photovoltaic panels to replace or inspect the photovoltaic panels and other components located above. The existing ladders are vertical. After workers climb to the top of the photovoltaic panels, they need to bring up the ladder again because the photovoltaic panel mounting frame and the photovoltaic panels are inclined surfaces. Then, the ladder is placed against the photovoltaic panel mounting frame located above. The workers can move on the ladder to move to photovoltaic panels at different positions, and the workers can replace or inspect each photovoltaic panel.

[0045] Since the existing ladder is used, the ladder needs to be abutted against the photovoltaic panel mounting frame. After the worker steps on the ladder, the ladder causes great pressure on the photovoltaic panel mounting frame, causing the photovoltaic panel mounting frame to deform. Moreover, when the ladder is abutted against the photovoltaic panel mounting frame, since the abutment area of ​​the ladder against the photovoltaic panel mounting frame is small, it is easy for the ladder to abut against the photovoltaic panel, which can easily cause damage to the photovoltaic panel. Moreover, since the distance between the ladder and the photovoltaic panel is very small, it is easy for the worker to step on the photovoltaic panel by mistake. That is, the use of the existing ladder can easily cause damage to the photovoltaic panel and the photovoltaic panel mounting frame.

[0046] In order to solve the technical problem that the existing ladders easily cause damage to photovoltaic panels and photovoltaic panel mounting frames, the present application proposes a bending ladder for photovoltaic panels, including a fixed base, a first ladder frame, a second ladder frame, a rotating assembly, an angle adjustment assembly and an angle locking assembly; the first ladder frame is vertically arranged on the fixed base, and the end of the first ladder frame away from the fixed base is rotatably connected to one end of the second ladder frame through the rotating assembly; the angle adjustment assembly includes a telescopic member and a driving member, one end of the telescopic member is connected to the first ladder frame, the other end of the telescopic member is connected to the second ladder frame, the driving member is connected to the telescopic member, and the driving member is used to adjust the telescopic amount of the telescopic member to adjust the angle between the first ladder frame and the second ladder frame; the angle locking assembly is connected to the rotating assembly, and the angle locking assembly is used to limit the rotation of the rotating assembly to lock the angle between the first ladder frame and the second ladder frame.

[0047] When using the folding ladder for photovoltaic components of the present application, after moving the fixed base to a suitable position, the angle between the first ladder frame and the second ladder frame is adjusted by the angle adjustment assembly, and the distance between the second ladder frame and the photovoltaic panel is adjusted to be appropriate, so that workers can inspect and repair the photovoltaic panel. When the second ladder frame is adjusted to a suitable position, the angle between the first ladder frame and the second ladder frame is locked by the angle locking assembly to prevent the second ladder frame from rotating when the worker is working on the second ladder frame, so that the angle between the first ladder frame and the second ladder frame is fixed, thereby ensuring the safety of the workers on the second ladder frame and preventing the second ladder frame from pressing on the photovoltaic panel. Since the second ladder frame of the folding ladder for photovoltaic components of the present application is arranged on the first ladder frame, and the first ladder frame is arranged on the fixed base, the folding ladder for photovoltaic components of the present application does not contact the photovoltaic component, thereby avoiding applying pressure to the photovoltaic panel mounting frame and the photovoltaic panel, and avoiding damage to the photovoltaic panel and the photovoltaic panel mounting frame during maintenance.

[0048] The following specific embodiments are combined with the accompanying drawings to describe the technical solution of the application in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0049] Reference Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 A schematic diagram of the structure of a bending ladder for a photovoltaic module provided in an embodiment of the present application; Figure 2 A schematic structural diagram of the connection between the first ladder frame and the second ladder frame in the bending ladder for photovoltaic modules provided in an embodiment of the present application; Figure 3 for Figure 2 Schematic diagram of the enlarged structure at point A in the middle.

[0050] In the embodiments of this application, refer to Figures 1 to 3 As shown, an embodiment of the present application provides a bending ladder for a photovoltaic assembly, including a fixed base 100, a first ladder frame 200, a second ladder frame 300, a rotating assembly 400, an angle adjustment assembly 500 and an angle locking assembly 600.

[0051] The first ladder frame 200 is vertically disposed on the fixed base 100 , and one end of the first ladder frame 200 away from the fixed base 100 is rotatably connected to one end of the second ladder frame 300 through a rotating assembly 400 .

[0052] The angle adjustment assembly 500 includes a telescopic member 510 and a driving member 520. One end of the telescopic member 510 is connected to the first ladder frame 200, and the other end of the telescopic member 510 is connected to the second ladder frame 300. The driving member 520 is connected to the telescopic member 510. The driving member 520 is used to adjust the telescopic amount of the telescopic member 510 to adjust the angle between the first ladder frame 200 and the second ladder frame 300.

[0053] The angle locking assembly 600 is connected to the rotating assembly 400 , and the angle locking assembly 600 is used to limit the rotation of the rotating assembly 400 to lock the angle between the first ladder frame 200 and the second ladder frame 300 .

[0054] The fixed base 100 of the present application is used to be set on the ground, usually placed directly on the ground. In order to prevent the fixed base 100 from tipping over, anchor bolts can be set on the fixed base 100 to fix the fixed base 100 on the ground.

[0055] The first ladder frame 200 and the second ladder frame 300 are ladder structures. The structures of the first ladder frame 200 and the second ladder frame 300 can be the same or different. The first ladder frame 200 is vertically arranged on the fixed base 100. The end of the first ladder frame 200 away from the fixed base 100 is rotatably connected to one end of the second ladder frame 300 through a rotating assembly 400, that is, the second ladder frame 300 can rotate relative to the first ladder frame 200. The first ladder frame 200 is used for workers to climb to the position of the second ladder frame 300 above.

[0056] The angle adjustment assembly 500 is used to adjust the angle between the first ladder frame 200 and the second ladder frame 300, so as to change the distance between the second ladder frame 300 and the photovoltaic panel.

[0057] The angle locking assembly 600 is used to limit the rotation of the rotating assembly 400 to lock the angle between the first ladder frame 200 and the second ladder frame 300. When the angle adjustment assembly 500 adjusts the angle between the first ladder frame 200 and the second ladder frame 300 to a suitable position, the angle between the first ladder frame 200 and the second ladder frame 300 is locked by the angle locking assembly 600 to prevent the second ladder frame 300 from rotating, thereby ensuring the personal safety of workers working on the second ladder frame 300 and preventing the second ladder frame 300 from pressing the photovoltaic panel.

[0058] When using the bending ladder for photovoltaic modules of the present application, after moving the fixed base 100 to a suitable position, the angle between the first ladder frame 200 and the second ladder frame 300 is adjusted by the angle adjustment assembly 500, and is adjusted to make the distance between the second ladder frame 300 and the photovoltaic panel appropriate to facilitate workers to inspect and repair the photovoltaic panel. When the second ladder frame 300 is adjusted to a suitable position, the angle between the first ladder frame 200 and the second ladder frame 300 is locked by the angle locking assembly 600 to prevent the second ladder frame 300 from rotating when the workers are working on the second ladder frame 300, so that the angle between the first ladder frame 200 and the second ladder frame 300 is fixed, thereby ensuring the safety of the workers on the second ladder frame 300 and preventing the second ladder frame 300 from pressing on the photovoltaic panel. Since the second ladder frame 300 of the bending ladder for photovoltaic components of the present application is arranged on the first ladder frame 200, and the first ladder frame 200 is arranged on the fixed base 100, the bending ladder for photovoltaic components of the present application does not contact the photovoltaic components, thereby avoiding applying pressure to the photovoltaic panel mounting frame and the photovoltaic panel, and avoiding damage to the photovoltaic panel and the photovoltaic panel mounting frame during maintenance.

The fixed seat 630 is configured to move in the slide 620 to drive the stopping claw 640 to be engaged in the tooth groove of the rotating gear 610 or to be disengaged from the tooth groove of the rotating gear 610 so as to lock or unlock the rotating gear 610.

[0061] In this embodiment, refer to Figure 2 and Figure 3 As shown, the fixing seat 630 is slidably connected to the slideway 620, and the fixing seat 630 can be Figure 2 When the locking claw 640 is moved to the bottom of the rotating gear 610, the locking claw 640 is engaged with the tooth groove of the rotating gear 610, so that the rotating gear 610 cannot rotate, that is, the rotating gear 610 is locked. Since the rotating gear 610 is installed on the rotating shaft 420, the rotating shaft 420 cannot rotate either, so that the angle between the first ladder frame 200 and the second ladder frame 300 is fixed, and the second ladder frame 300 cannot rotate.

[0062] When unlocking is required, the fixed seat 630 is slid, and the fixed seat 630 drives the locking claw 640 to fall off the tooth groove of the rotating gear 610, so that the rotating gear 610 can rotate freely, that is, the rotating gear 610 is unlocked, so that the rotating shaft 420 can also rotate, so that the angle between the first ladder frame 200 and the second ladder frame 300 can be changed, and the second ladder frame 300 can rotate freely.

In specific use, after the angle locking assembly 600 is used to lock the angle between the first ladder frame 200 and the second ladder frame 300, the locking pin 700 is inserted into the first pin hole 411 and the second pin hole 421.
