DETAILED DESCRIPTION
[0040] The utility model embodiment discloses a photovoltaic cleaning device, wherein a gap can be formed between the anti-warping head component and the traveling component to ensure that the photovoltaic component is located between the traveling component and the anti-warping head component during use, and the anti-warping head component is used to press against the back side of the photovoltaic component to reduce or even avoid the traveling component from being separated from the sun-facing side of the photovoltaic component, thereby reducing the degree of "warping" of the photovoltaic cleaning device or eliminating the "warping head" phenomenon, which is conducive to making the roller brush of the device body fit the surface of the photovoltaic component and improving the cleaning effect.
[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The anti-warping head component includes a limiting wheel, and the limiting wheel includes a fixedly connected limiting wheel part 121 and an anti-slip wheel part 122; the limiting wheel part 121 is located between the device body 100 and the anti-slip wheel part 122; the anti-slip wheel part 122 can press against the back of the photovoltaic module 201; the size of the cross section of the anti-slip wheel part 122 along the direction perpendicular to the axis of the limiting wheel part 121 is greater than the size of the cross section of the limiting wheel part 121 along the direction perpendicular to its own axis; and / or the anti-warping head component includes an elastic suspension wheel 106, and the elastic suspension wheel 106 is kept pressed against the back of the photovoltaic module 201 by its own elastic action.
[0043] Those skilled in the art can understand that the photovoltaic module 201 is arranged at an angle at the power generation site, with the higher end being the upper end and the lower end being the lower end; the surface of the photovoltaic module 201 facing the sunlight is the sun-facing side, and the surface of the photovoltaic module 201 opposite to the sun-facing side is the back side.
[0044] When the photovoltaic cleaning device is used to perform cleaning or charging tasks, the device body 100 is arranged on the sunny side of the photovoltaic module 201; the device body 100 is provided with a walking component for walking along the sunny side of the photovoltaic module 201. In some embodiments, the walking component includes an upper walking component 101 and a lower walking component 103, the upper walking component 101 moves along the upper end of the sunny side of the photovoltaic module 201, and the lower walking component 103 moves along the lower end of the sunny side of the photovoltaic module 201. The photovoltaic module 201 is clamped in the gap formed between the walking component and the anti-warping component, wherein the anti-warping component can press against the back of the photovoltaic module 201; if the photovoltaic cleaning equipment is affected by factors such as the uneven speed of the upper walking component 101 and the lower walking component 103, the difference in spacing between adjacent photovoltaic modules 201, etc., resulting in the walking component tending to separate from the sunny side of the photovoltaic module 201, at this time, the anti-warping component presses against the back of the photovoltaic module 201, causing the walking component to only separate from the sunny side of the photovoltaic module 201 by a small distance or unable to separate from the sunny side of the photovoltaic module 201, thereby reducing or even avoiding the "warping" of the photovoltaic cleaning equipment, and causing the roller brush 105 of the equipment body 100 to fit the surface of the photovoltaic module 201, thereby achieving the purpose of improving the cleaning effect.
[0045] Those skilled in the art can understand that the device body 100 can be equipped with an upper limit wheel 102 and a lower limit wheel 104, which are respectively used to move close to the upper end surface and the lower end surface of the photovoltaic module 201.

When the limiting wheel used as the anti-warping component is arranged as the upper limiting wheel 102, its anti-slip wheel portion 122 can press against the upper end of the back side of the photovoltaic module 201. The diameter of the anti-slip wheel portion 122 gradually increases in the direction away from the limiting wheel portion 121.

The advantage of this structure is that in the early stage of "warping", the upper end of the photovoltaic cleaning device is immediately subject to the resistance applied by the photovoltaic module 201 to the side of the anti-slip wheel part 122, and the higher the degree of "warping", the greater the resistance, thus minimizing the probability of the "warping" phenomenon and the severity of the "warping" phenomenon, and reducing or even avoiding the formation of a cleaning blind area on the photovoltaic module 201.
[0049] In another specific embodiment, the outer peripheral surface of the anti-slip wheel portion 122 is a conical surface, and the diameter of the end of the anti-slip wheel portion 122 close to the limiting wheel portion 121 is D1, and the diameter of the end away from the limiting wheel portion 121 is D2, wherein 1.1*D1<D2<3*D1. In the solution provided in this embodiment, the outer peripheral surface of the anti-slip wheel portion 122 is set to a conical surface, which has a simpler structure and lower manufacturing cost.
[0050] In the photovoltaic cleaning device, the diameters of the limiting wheel portion 121 are uniform at various locations; the diameter D1 of one end of the anti-slip wheel portion 122 close to the limiting wheel portion 121 is consistent with the diameter of the limiting wheel portion 121 .
[0051] The limiting wheel portion 121 and the anti-slip wheel portion 122 may be arranged to be connected as one body. The outer circumference of the limiting wheel portion may be provided with a tire pattern to increase the friction between the limiting wheel portion 121 and the end face of the photovoltaic module 201 .

The annular body 1221, the central shaft inserting cylinder 1222 and the connecting plate 1223 can be set as an integrated structure, and the three are respectively connected to the limiting wheel portion 121 as a whole.
[0053] In another embodiment, the anti-warping component is an elastic suspension wheel 106, and the elastic suspension wheel 106 includes:
[0054] A telescopic rod, a first end of which is mounted on the device body 100;
[0055] A rotating wheel, which is rotatably mounted on the second end of the telescopic rod around its main line;
[0056] The spring is sleeved on the telescopic rod and provides an extension driving force to the telescopic rod so that the rotating wheel is pressed against the back side of the photovoltaic component 201.
[0057] The first end of the telescopic rod can be arranged to be mounted on the device body 100 through a bracket, and can also be arranged to be mounted on the device body 100 through an anti-detachment hook 107. The anti-detachment hook 107 is fixed to the device body 100. The anti-detachment hook 107 is L-shaped, including a first bending rod and a second bending rod connected to each other, the end of the first bending rod is fixed to the device body 100, and the second bending rod is located on the back side of the photovoltaic module 201; the first end of the telescopic rod is installed on the surface of the second bending rod facing the photovoltaic module 201.
[0058] The photovoltaic cleaning equipment provided in this embodiment has a simple structure, is easy to manufacture, and has a low production cost.
