[0028] See Figures 1 to 9 , this embodiment provides a maintenance pedal for a photovoltaic module, including a pedal main body 1. At least four hanging hooks 2 are provided at the edge of the pedal main body 1. The four hanging hooks 2 extend towards the same side of the pedal main body 1. Two hanging hooks 2 at one end can be hung on the upper aluminum frame 301 of the photovoltaic module 3, and two hanging hooks 2 at the other end can lean against the upper aluminum frame 301 of the adjacent photovoltaic module 3 below. Function: By including a pedal main body, at least four hanging hooks are provided at the edge of the pedal main body, and the four hanging hooks extend towards the same side of the pedal main body. Two hanging hooks at one end can be hung on the upper aluminum frame of the photovoltaic module, and two hanging hooks at the other end can lean against the upper aluminum frame of the adjacent photovoltaic module below; thereby enabling the pedal main body to be stably placed on the photovoltaic module by using the hanging hooks for personnel operation, and it can be used in power stations with an inclination angle of 30 degrees.

[0029] Specifically, the hanging hook 2 can be fixed at different positions on the pedal body 1 to fit photovoltaic modules 3 of different widths. Function: The position of the hanging hook on the pedal body 1 can be adjusted to adapt to photovoltaic modules of different widths.

[0030] Specifically, the pedal body 1 is rectangular. The pedal body 1 includes two parallel brackets 101 and several tread bars 102 arranged between the two brackets 101. Function: The arrangement of the two brackets 101 and several tread bars 102 makes the pedal body 1 not only lightweight but also suitable for personnel to step on during operation. Preferably, the width of the bracket is slightly wider than that of the photovoltaic module to facilitate stable placement on the photovoltaic module for personnel to operate.

[0031] Specifically, two hanging hooks 2 are respectively arranged at both ends of one of the brackets 101, and the other two hanging hooks 2 are respectively arranged at both ends of the other bracket 101. The hanging hook 2 can be fixed at different positions on the bracket 101. Function: The hanging hook can be fixed at different positions on the bracket to fit photovoltaic modules of different widths. Preferably, the bracket can be in the shape of a straight and long guide rail to facilitate the movement and adjustment of the hanging hook.

[0032] Specifically, the pedal body 1 is made of aluminum alloy, and rubber sheaths 4 are respectively provided at both ends of the bracket 101. Function: Made of aluminum alloy, the total weight of the photovoltaic module maintenance pedal can be made about 5 kilograms, which can be picked up with one hand. The rubber sheath 4 can prevent the ends of the bracket 101 from being too sharp.

[0033] Specifically, the angle between the hanging hook 2 and the pedal body 1 can be adjusted. Function: By adjusting the angle between the hanging hook arranged at one end or both ends of the pedal body 1 and the pedal body 1, there is a height difference in the support at both ends of the bracket. Thus, when the maintenance pedal is placed on a photovoltaic module array installed at a certain angle of inclination, the bracket can be kept horizontal with the ground. Preferably, the angle between the hanging hook and the bracket 101 can be adjusted.

[0034] Specifically, the hanging hook 2 is at least composed of two parts. One end of the upper part is fixedly arranged on the pedal body 1, the other end of the upper part is connected to the lower part, and the lower part can rotate around the center of the connection point between the upper part and the lower part to the required angle and be fixed. Function: By rotating the lower part around the center of the connection point to the required angle and fixing it, the support of the inclined plane is realized. Preferably, one end of the upper part is fixedly arranged on the bracket.

[0035] Specifically, the main body of the hanging hook 2 is made of metal, and an elastomer is arranged outside the metal to prevent damage to the photovoltaic module 3. Function: In this way, it has both the strength of the metal and the elastic protection of the elastic part.

[0036] Specifically, the main body of the hanging hook 2 is the hanging hook aluminum alloy main body 201, and the elastomer is the hanging hook rubber sheath 202 or polyurethane elastomer. Function: The selection and combination of these materials are relatively appropriate.

[0037] Specifically, the elastomer at the lower part of the hanging hook 2 is provided with a hanging hook flange 203. Function: The setting of the hanging hook flange 203 can enable the hanging hook 2 to better hang and lean on the upper ends of the aluminum frames of two adjacent upper and lower photovoltaic modules, so as to support the bracket and further support the pedal main body 1.

[0038] Therefore, the utility model can be used on roof photovoltaic modules and has good portability.

[0039] Preferably, the bracket is made of carbon fiber reinforced composite material and metal material.

[0040] Further preferably: The metal material is titanium alloy.

[0041] Preferably: The carbon fiber reinforced composite material and the titanium alloy material of the bracket are fixed by blind rivets.

[0042] The above is the preferred embodiment of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and retouches can still be made, and these improvements and retouches are also regarded as the protection scope of the utility model.
