[0020] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] like Figure 1 and Figure 2 As shown, the photovoltaic module cleaning device of the embodiment of the present invention includes a bracket 1, a drive motor 5 and an electrostatic dry wipe 3. The bracket 1 is provided with a pulley 2, which is used for sliding cooperation with the photovoltaic module 8. The drive motor 5 is arranged on the bracket 1 and is used for driving the pulley 2 to move along the photovoltaic module 8. The electrostatic dry wipe 3 is arranged on the end face of the bracket 1 facing the photovoltaic module 8.

[0022] It can be understood that when the photovoltaic component 8 needs to be cleaned, the driving motor 5 can be used to drive the bracket 1 to move along the photovoltaic component 8, and the electrostatic dry wipe 3 opposite to the photovoltaic component 8 can use the strong adsorption ability of the polymer particles to rely on friction electrostatic adsorption of dust, lint, fine particles, etc. on the surface of the photovoltaic component 8. While cleaning the photovoltaic component 8, no water stains will be left. This can solve the problems of high cost and many constraints of traditional water washing without damaging the on-site environment, and can utilize the application of photovoltaic projects in the Shagohuang area.

[0023] The photovoltaic module cleaning device of the embodiment of the present invention is characterized in that the bracket 1 is provided with a pulley 2, which is used for sliding cooperation with the photovoltaic module 8. The driving motor 5 is arranged on the bracket 1 and is used for driving the pulley 2 to move along the photovoltaic module 8. The electrostatic dry wipe 3 is arranged on the end surface of the bracket 1 facing the photovoltaic module 8. Therefore, the driving motor 5 drives the bracket 1 to move, which can drive the electrostatic dry wipe 3 to absorb dust and particulate matter on the surface of the photovoltaic module 8. The device has low cost, does not require a water source, is easy to operate, and solves the problem of difficulty in using photovoltaic projects in the deserted area.

[0024] Furthermore, if Figure 1 and Figure 2 As shown, the bracket 1 includes a top plate 11 and two side plates 12, the top plate 11 extends along a first direction, the two side plates 12 are respectively connected to the two ends of the top plate 11, and the two side plates 12 are respectively clamped on the two sides of the photovoltaic module 8, and the electrostatic dry wipes 3 are arranged on the top plate 11. It should be noted that the conventional photovoltaic modules 8 on the market are mostly regular rectangular structures, and the bracket 1 of the present application is in the form of a buckle plate to clamp the two side frames of the photovoltaic module 8, which is firmly assembled and has good movement stability.

[0025] Preferably, the pulley 2 is disposed on the side plate 12. In other words, the pulley 2 moves along the side frame of the photovoltaic assembly 8 without interfering with the electric panels of the photovoltaic assembly 8.

[0026] Further, in the second direction, the pulley 2 is located on one side of the side plate 12, and the second direction is perpendicular to the first direction and parallel to the top plate 11. In other words, the pulley 2 is arranged on the side of the side plate 12, so that the pulley 2 does not occupy the width space, which is conducive to the miniaturization of the device.

[0027] Furthermore, if Figure 1 and Figure 2 As shown, the side plate 12 includes an opposite front side and a rear side in the second direction, and the front side and the rear side are both provided with pulleys 2. That is, both sides of the side plate 12 are provided with pulleys 2, and the sliding stability and reliability are better.

[0028] Preferably, the pulley 2 has a slide groove, and the side of the photovoltaic assembly 8 in the first direction is slidably matched with the slide groove. Therefore, the cooperation between the slide groove and the side of the photovoltaic assembly 8 can, on the one hand, use the side to guide the moving track of the pulley 2 to avoid deviation, and on the other hand, the slide grooves on both sides clamp the frame to achieve the effect of assembly and fixation, and prevent the bracket 1 from falling off the photovoltaic assembly 8.

[0029] In some embodiments, the photovoltaic module cleaning device further includes a solar panel 7 and a battery 6, both of which are arranged on the bracket 1, and the battery 6 is used to store the electric energy output by the solar panel 7 and supply power to the driving motor 5. Thus, the solar panel 7 can directly use solar energy to supply power to the driving motor 5 without external power supply, and the battery 6 can store electricity to ensure that the cleaning device can be used around the clock.

[0030] Preferably, the side plate 12 has an installation cavity, the drive motor 5 and the battery 6 are arranged in the installation cavity, and the solar panel 7 is laid on the end surface of the top plate 11 away from the electrostatic dry wipe 3. As shown in Figure x, the solar panel 7 is laid on the upper surface of the top plate 11 to collect solar energy, and the drive motor 5 and the battery 6 are arranged in the installation cavity. The bracket 1 can be used to protect the drive motor 5 and the battery 6, and at the same time, they can be hidden to reduce space occupation.

[0031] Preferably, an electrostatic dry wipe storage box 4 is provided on the top plate 11. Thus, after the electrostatic dry wipe 3 completes one cleaning, a new one can be directly taken out from the electrostatic dry wipe storage box 4 for standby use, which is convenient to operate.

[0032] Optionally, a robotic arm may be provided on the bracket 1 to replace the electrostatic dry wipes 3 manually.

[0033] In some embodiments, the top plate 11 includes a fixed section and a movable section, and the movable section is retractable relative to the fixed section. It should be noted that the frame widths of different photovoltaic modules 8 may be different. In this application, the top plate 11 is set as a retractable structure, and the width of the bracket 1 can be adjusted according to demand to facilitate adaptation to different models of photovoltaic modules 8, with high application flexibility.
