DETAILED DESCRIPTION

[0029] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0030] In the related art, when installing and maintaining photovoltaic modules, traditional ladders are usually used as tools for installing and maintaining photovoltaic panels. However, when using traditional ladders to install and maintain photovoltaic panels, it is not convenient for workers to stay stable on the photovoltaic panels, especially when the photovoltaic panels are at a certain angle to the ground, and the use of traditional ladders will make the working environment of the workers unstable.

[0031] In view of this, the embodiment of the present application realizes movement on the photovoltaic panel by setting two walking pedals. By setting a rotating base under the two walking pedals respectively, the rotating base can drive the two walking pedals to rotate relative to the photovoltaic panel, thereby changing the horizontal orientation of the photovoltaic panel maintenance device. And when the photovoltaic panel maintenance device adjusts the moving direction, the staff can walk alternately on the two walking pedals, so that they can move on the photovoltaic panel in the expected direction. The embodiment of the present application connects the two walking pedals through a universal joint, so that the staff can adjust the angle between the two walking pedals according to the specific working environment needs, thereby ensuring the stability of the working state. The embodiment of the present application sets a universal shaft between the walking pedal and the rotating base, so that in the process of maintaining the photovoltaic panel, the staff can adjust the universal shaft according to the inclination of the photovoltaic panel, and by twisting the universal shaft, the standing board connected to the universal shaft can be kept level with the ground, thereby improving the stability of the working environment.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] Figure 1 This is a schematic diagram of the structure of the photovoltaic panel maintenance device provided in this application. Figure 1As shown, the photovoltaic panel maintenance device includes a first walking pedal 100 and a second walking pedal 200, and the first walking pedal 100 and the second walking pedal 200 include respective corresponding standing boards 300; side rods 400 are respectively arranged on opposite sides of the two standing boards 300, and the side rods 400 of the first walking pedal 100 and the second walking pedal 200 are movably connected; a rotating base 500 is arranged at the bottom of each standing board 300, and the rotating base 500 is connected to the standing board 300 through a universal shaft 600, and the rotating base 500 drives the universal shaft 600 to rotate circumferentially, so that the universal shaft 600 drives the standing board 300 to rotate, and the universal shaft 600 rotates to change the angle between the standing board 300 and the photovoltaic panel. That is to say, through the setting of the above-mentioned rotating base 500, the staff can adjust the direction of the photovoltaic panel maintenance device on the standing board 300, which is convenient for the staff to maintain and maintain the photovoltaic panel, and there is no need to move or adjust the photovoltaic panel maintenance device on the photovoltaic panel, thereby improving the maintenance efficiency. In addition, by arranging a universal joint 600 between the walking pedal and the rotating base 500, during the maintenance of the photovoltaic panel, the staff can adjust the universal joint 600 according to the inclination of the photovoltaic panel, and by twisting the universal joint 600, the standing board 300 connected to the universal joint 600 can be kept level with the ground, thereby improving the stability of the working environment.

[0034] Figure 3 The schematic diagram of the structure of the universal shaft of the photovoltaic panel maintenance device provided in this application. Figure 3 The universal shaft 600 of the photovoltaic panel maintenance device is further described.

[0035] In a possible embodiment, the universal shaft 600 includes a first bearing sleeve 601 and a second bearing sleeve 602, the first bearing sleeve 601 and the second bearing sleeve 602 are connected by a cross shaft, and the first bearing sleeve 601 and the second bearing sleeve 602 are also connected by a fixing bar 603. In other words, the cross shaft connects the first bearing sleeve 601 and the second bearing sleeve 602, which can play a role in transmitting torque and force. When the second bearing sleeve 602 is twisted, the cross shaft can transfer the torsional force of the first bearing sleeve 601 to the second bearing sleeve 602. When the rotating base 500 rotates, the universal shaft 600 can drive the standing plate 300 connected thereto to rotate, and then drive the entire photovoltaic panel maintenance device to rotate. Further, the first bearing sleeve 601 and the second bearing sleeve 602 are also connected by a fixing bar 603.

[0036] Preferably, the first bearing sleeve 601 and the second bearing sleeve 602 are detachably connected to the fixing bar 603. That is, when the fixing bar 603 is connected to the first bearing sleeve 601 and the second bearing sleeve 602, the fixing bar 603 can limit the torsion between the first bearing sleeve 601 and the second bearing sleeve 602, and the universal shaft 600 cannot adjust the angle between the standing plate 300 and the photovoltaic panel in the above state. When the fixing bar 603 is separated from the first bearing sleeve 601 and the second bearing sleeve 602, the first bearing sleeve 601 and the second bearing sleeve 602 can be torsion, thereby adjusting the angle between the standing plate 300 and the photovoltaic panel. By providing the fixing bar 603, it can provide additional support and connection for the first bearing sleeve 601 and the second bearing sleeve 602, so that the universal shaft 600 can remain stable when transmitting the rotational force of the rotating base 500.

[0037] In a possible implementation, one end of the fixing bar 603 is connected to the wall of the first bearing sleeve 601 through a fixing bolt 604, and the other end of the fixing bar 603 is connected to the connection between the second bearing sleeve 602 and the cross shaft through a fixing bolt 604. In other words, the fixing bar 603 is movably connected to the first bearing sleeve 601 and the second bearing sleeve 602 through the fixing bolt 604. The angle between the standing board 300 and the photovoltaic panel is adjusted by loosening the fixing bolt 604 between the fixing bar 603 and the second bearing sleeve 602. Preferably, the number of the fixing bars 603 is 4.

[0038] Figure 4 The schematic diagram of the structure of the universal joint of the photovoltaic panel maintenance device provided in this application. Figure 4 The photovoltaic panel maintenance device provided in this application is further explained.

[0039] In a possible implementation, the first walking pedal 100 and the second walking pedal 200 are connected via a universal joint 800, one end of the universal joint 800 is plugged into the side rod 400 of the first walking pedal 100, and the other end of the universal joint 800 is plugged into the side rod 400 of the second walking pedal 200, wherein the angle between the first walking pedal 100 and the second walking pedal 200 is changed by the movable universal joint 800. That is, the photovoltaic panel maintenance device provided in the present application enables the first walking pedal 100 and the second walking pedal 200 to be movably connected via two universal joints 800, and enables the first walking pedal 100 and the second walking pedal 200 to move relative to each other via the movable universal joint 800.

[0040] Optionally, two side rods 400 located on the same side of the first walking pedal 100 and the second walking pedal 200 are connected through a universal joint 800, and another two side rods 400 located on the same side of the first walking pedal 100 and the second walking pedal 200 are connected through a universal joint 800. The universal joint 800 and the side rod 400 may be movably connected, for example, the universal joint 800 and the side rod 400 are plugged.

[0041] In the specific implementation process, the angle between the first walking pedal 100 and the second walking pedal 200 can be changed by moving the universal joint 800 between the first walking pedal 100 and the second walking pedal 200. When the photovoltaic panel maintenance device needs to be rotated, the staff can use the universal joint 800 as the rotation point and rotate the first walking pedal 100 around the universal joint 800 in the direction close to the second walking pedal 200, so that the first walking pedal 100 can leave the photovoltaic panel. After the first walking pedal 100 leaves the photovoltaic panel, the staff can rotate the photovoltaic panel maintenance device by rotating the base 500. Furthermore, when changing the angle between the first walking pedal 100 and the second walking pedal 200, one of the universal joints 800 can also be pulled out from the side rod 400, so that the angle between the first walking pedal 100 and the second walking pedal 200 can be changed in a larger range. By providing the universal joint 800, the rotating base 500 can drive the two walking pedals to rotate relative to the photovoltaic panel, thereby changing the direction of the photovoltaic panel maintenance device, so that the staff can move in the desired direction through the two walking pedals. In addition, by providing the universal joint 800, the angle between the first walking pedal 100 and the second walking pedal 200 can be flexibly adjusted, so that the staff can adjust the working state of the photovoltaic panel maintenance device at different positions and angles to adapt to different working environments.

[0042] Figure 2 The schematic diagram of the structure of the rotating base of the photovoltaic panel maintenance device provided in this application. Figure 2 The rotating base 500 of the photovoltaic panel maintenance device is further described.

[0043] In a possible embodiment, the rotating base 500 includes a rotating rod 501, a sleeve 502, a rotating table 503 and a rotating bottom plate 505. The top of the rotating table 503 is fixedly connected to the universal shaft 600, and the bottom of the rotating table 503 is connected to the rotating rod 501 through a fixed block 504. The sleeve 502 is arranged on the rotating bottom plate 505, and the rotating rod 501 rotates in the sleeve 502. The rotating rod 501 drives the fixed block 504 and the rotating table 503 to rotate, so as to drive the universal shaft 600 and the standing board 300 to rotate. In other words, the setting of the rotating base 500 can drive the universal shaft 600 and the standing board 300 to rotate, so that the staff can easily adjust the position and angle of the photovoltaic panel maintenance device on the photovoltaic panel, which is convenient for the maintenance and care of the photovoltaic panel, and avoids the staff manually moving to adjust the position of the photovoltaic panel maintenance device.

[0044] Optionally, a bearing is provided at the bottom of the sleeve 502. The rotating rod 501 is connected to the bearing, and the rotating rod 501 rotates in the sleeve 502 through the bearing. Providing the bearing at the bottom of the sleeve 502 helps to support the rotating rod 501, and can reduce the friction resistance of the rotating rod 501 rotating in the sleeve 502, so that the rotation of the rotating rod 501 is more stable and smooth.

[0045] In a possible embodiment, a through hole is provided on the sleeve 502, and a stop bolt 506 is provided in the through hole. The length of the stop bolt 506 is greater than the depth of the through hole. The stop bolt 506 is tightened to limit the rotation of the rotating rod 501. In other words, the stop bolt 506 can contact the rotating rod 501 through the through hole on the sleeve 502. When the stop bolt 506 is inserted into the through hole and close to the rotating rod 501, the stop bolt 506 can limit the rotation of the rotating rod 501 in the sleeve 502. When the position of the photovoltaic panel maintenance device needs to be adjusted, the staff can reversely rotate the stop bolt 506 to keep it away from the rotating rod 501, thereby restoring the rotation ability of the rotating rod 501. Through the setting of the above-mentioned stop bolt 506, the staff can limit the rotation range of the rotating rod 501 when adjusting the position of the photovoltaic panel maintenance device, and the rotation angle can be effectively controlled by adjusting the tightening degree of the stop bolt 506 to prevent excessive rotation.

[0046] In a possible implementation, a reinforcing rib 508 is further provided at the bottom of the shaft sleeve 502, one end of the reinforcing rib 508 is connected to the shaft sleeve 502, and the other end of the reinforcing rib 508 is connected to the rotating base plate 505. By providing the reinforcing rib 508, the bottom structural strength of the shaft sleeve 502 can be effectively increased, so that the connection between the rotating base plate 505 and the shaft sleeve 502 is more stable, thereby improving the bearing capacity and stability of the entire rotating base 500.

[0047] In a possible embodiment, the length of the rotating rod 501 is greater than the length of the sleeve 502, and a rotating handle 507 is provided on the rotating rod 501, and the rotating handle 507 is arranged between the fixed block 504 and the sleeve 502, and the rotating handle 507 is inserted into the rotating rod 501 in the radial inward direction of the rotating rod 501. In other words, the rotating rod 501 can be partially inserted into the sleeve 502, and there is a part of the rotating rod 501 placed outside the sleeve 502. That is, there is a distance between the sleeve 502 and the fixed block 504, and the above distance is the length of the rotating rod 501 exceeding the sleeve 502. Through the above arrangement, the rotating handle 507 can be arranged on the rotating rod 501 between the sleeve 502 and the fixed block 504. Through the arrangement of the rotating handle 507, the staff can control the rotation of the rotating rod 501 through the rotating handle 507, making the operation more convenient. And the arrangement of the rotating handle 507 can prevent the staff from directly contacting the rotating rod 501, reduce the potential safety hazards during the operation, and improve the safety of the operation.

[0048] In a possible implementation, a rubber pad 700 is provided under the rotating bottom plate 505, and the cross-sectional area of ​​the rubber pad 700 is greater than the cross-sectional area of ​​the rotating bottom plate 505, and the cross-sectional area of ​​the rubber pad 700 is smaller than the cross-sectional area of ​​the standing plate 300. The provision of the rubber pad 700 can protect the photovoltaic panel. By providing the rubber pad 700 with a cross-sectional area greater than that of the rotating bottom plate 505, the pressure of personnel and the photovoltaic panel maintenance device on the photovoltaic panel can be dispersed to avoid damage to the photovoltaic panel. In addition, the rubber pad 700 can also play an anti-slip role, and can increase the friction between the photovoltaic panel maintenance device and the photovoltaic panel, especially when the photovoltaic panel is at a certain angle, the rubber pad 700 can increase the stability of the photovoltaic panel maintenance device.

[0049] In a possible implementation, at least one crossbeam 900 is disposed between the side bars 400 on both sides of the first walking pedal 100 and the second walking pedal 200. Optionally, a plurality of crossbeams 900 are disposed between the side bars 400 on both sides of the first walking pedal 100 and the second walking pedal 200, and each crossbeam 900 is vertically connected to the side bars 400. For example, two crossbeams 900 are disposed between the side bars 400 on both sides of the second walking pedal 200, and the two crossbeams 900 are spaced apart. By arranging the crossbeam 900 between the side bars 400, the structural stability and rigidity of the first walking pedal 100 and the second walking pedal 200 can be increased, the deformation and shaking between the side bars 400 can be reduced, and the stability of the first walking pedal 100 and the second walking pedal 200 can be improved.
