[0037] Photovoltaic power generation refers to a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. It mainly consists of three parts: photovoltaic panels, controllers, and inverters.

[0038] In existing technologies, photovoltaic modules are typically installed on rooftops. The photovoltaic panels are mounted on the existing roof using mounting frames to absorb sunlight and generate electricity.

[0039] However, since photovoltaic panels are installed outdoors, a large amount of dust will accumulate on their surface during long-term operation, blocking the absorption of sunlight and thus affecting the power generation of the photovoltaic modules.

[0040] To address the aforementioned issues, this application provides a photovoltaic module cleaning device. The device comprises a cleaning rod mounted on a mounting frame, with a cleaning component mounted on the rod for cleaning the photovoltaic panels. A wind cup is incorporated, which rotates under wind power. The wind cup drives a transmission component, which in turn drives the cleaning rod to slide back and forth on the mounting frame, thus enabling the cleaning component to reciprocate and clean the photovoltaic panels. This wind-driven cleaning of the photovoltaic modules reduces dust accumulation and ensures the normal operation of the photovoltaic modules.

[0041] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0042] This application provides a photovoltaic module cleaning device, referring to... Figures 1 to 6 The photovoltaic module cleaning device includes a mounting frame 100, a cleaning rod 200, a wind cup 300, a transmission assembly 400, and a cleaning assembly 500.

[0043] A photovoltaic panel 600 is mounted on the mounting frame 100. A cleaning rod 200 is slidably mounted on the mounting frame 100 and located above the photovoltaic panel 600. A cleaning assembly 500 is mounted on the cleaning rod 200 for cleaning the photovoltaic panel 600. A wind cup 300 is rotatably mounted on the mounting frame 100. A transmission assembly 400 is mounted on the mounting frame 100 and connected to the cleaning rod 200 and the wind cup 300 respectively to transmit the power of the wind cup 300 and drive the cleaning rod 200 to slide back and forth.

[0044] Among them, reference Figure 1 One end of the mounting frame 100 is higher than the other end, so that the photovoltaic panel 600 mounted on the mounting frame 100 is tilted to improve the sunlight reception of the photovoltaic panel 600. Multiple photovoltaic panels 600 are configured and mounted on the upper surface of the mounting frame 100.

[0045] The wind cup 300 is mounted on the top of the higher end of the mounting bracket 100, and the rotation axis of the wind cup 300 is vertical. The wind cup 300 includes a rotating shaft and three cups. The main body is a hemispherical shell, and the three cups are evenly distributed and fixed to the top of the rotating shaft. The rotating shaft is rotatably connected to the mounting bracket 100 in the vertical direction. When the wind blows, the wind force blows the three cups, causing the rotating shaft to rotate, thereby realizing the wind-driven movement of the cleaning rod 200. There is no need to install a motor drive, reducing costs. At the same time, cleaning of the photovoltaic panel 600 does not need to be carried out continuously, but only when there is wind. Furthermore, in this embodiment, in order for the wind cup 300 to rotate better under the drive of the wind, a horizontal section is provided at the top of the mounting bracket 100, and the wind cup 300 is rotatably connected to the horizontal section.

[0046] In other embodiments, the wind cup 300 can also be replaced by an impeller, fan blades, etc., which will not be elaborated on here.

[0047] In some embodiments, the transmission assembly 400 is located at the bottom of the mounting bracket 100.

[0048] The transmission component 400 is installed at the bottom of the mounting frame 100. The mounting frame 100 and the photovoltaic panel 600 installed on it provide a certain degree of shade for the transmission component 400, reducing the transmission component 400 from sun and rain, so as to improve the service life of the transmission component 400.

[0049] In some embodiments, refer to Figure 2 and Figure 4 The cleaning rod 200 includes a mounting part 210 and two connecting parts 220. The two connecting parts 220 are respectively disposed at both ends of the mounting part 210. The mounting part 210 is located above the photovoltaic panel 600 and is used to install the cleaning assembly 500. The connecting parts 220 extend to the bottom of the mounting frame 100. The two ends of the connecting plate 410 are respectively connected to the two connecting parts 220.

[0050] Specifically, the two ends of the mounting portion 210 extend to the outer sides of the mounting frame 100, and two connecting portions 220 are respectively connected to the two ends of the mounting portion 210, so that the connecting portions 220 can extend to the bottom of the mounting frame 100 and connect with the transmission assembly 400. The mounting portion 210 slides from the bottom end of the mounting frame 100 toward the top end, and then returns from the top end of the mounting frame 100 to the bottom end, thus achieving reciprocating cleaning of the photovoltaic panel 600.

[0051] In some embodiments, the mounting portion 210 is detachably connected to the two connecting portions 220.

[0052] For example, the mounting part 210 is fixed to the two connecting parts 220 by bolts. In other embodiments, the mounting part 210 can also be fixed to the connecting parts 220 by means of clips or the like. The detachable connection of the mounting part 210 facilitates the removal of the mounting part 210 for replacement and maintenance of the cleaning component 500, thereby maintaining the cleaning effect.

[0053] In some embodiments, refer to Figure 2 The transmission assembly 400 includes a connecting plate 410, a reciprocating screw 420, and a transmission component 430. The connecting plate 410 is connected to the cleaning rod 200. The reciprocating screw 420 is rotatably mounted on the mounting bracket 100 and threaded onto the connecting plate 410. The transmission component 430 is connected to the reciprocating screw 420 and the air cup 300 respectively to drive the reciprocating screw 420 to rotate.

[0054] Both ends of the connecting plate 410 are connected to the connecting part 220, so that the cleaning rod 200 and the connecting plate 410 combine to form a rectangular frame structure that fits onto the mounting bracket 100, thus limiting the sliding of the cleaning rod 200. The reciprocating screw 420 is set along the length direction of the mounting bracket 100 so that the cleaning rod 200 can slide along the length direction of the mounting bracket 100. The reciprocating screw 420 is rotatably connected to the bottom of the mounting bracket 100. Two mounting blocks 110 are fixed to the bottom of the mounting bracket 100, and the reciprocating screw 420 is rotatably connected between the two mounting blocks 110. The connecting plate 410 has a threaded hole for threaded connection with the reciprocating screw 420. The characteristics of the reciprocating screw 420 enable the connecting plate 410 to move when the reciprocating screw 420 is rotated. When the connecting plate 410 moves to the end of the reciprocating screw 420, it automatically slides back along the reciprocating screw 420, thereby realizing the reciprocating movement of the connecting plate 410.

[0055] In some embodiments, the transmission member 430 includes a first bevel gear 431 and a second bevel gear 432. The first bevel gear 431 is connected to the wind cup 300 to rotate with the wind cup 300. The second bevel gear 432 is connected to the reciprocating screw 420 and meshes with the first bevel gear 431.

[0056] The first bevel gear 431 is connected to the bottom of the rotating shaft of the wind cup 300, which is rotatably connected to the mounting bracket 100 via a bearing. The second bevel gear 432 is fixed to the end of the reciprocating screw 420. The second bevel gear 432 has a certain deflection angle with the first bevel gear 431. Therefore, it is necessary to adjust the meshing angle of the first bevel gear 431 and the second bevel gear 432 so that the first bevel gear 431 can drive the second bevel gear 432 to rotate.

[0057] By adopting the above technical solution, under the drive of wind power, the wind cup 300 rotates, which drives the first bevel gear 431 to rotate. The first bevel gear 431 drives the second bevel gear 432 to rotate. The second bevel gear 432 drives the reciprocating screw 420 to rotate. The reciprocating screw 420 drives the connecting plate 410 to slide back and forth. The connecting plate 410 drives the cleaning rod 200 to slide back and forth on the photovoltaic panel 600, so as to realize the cleaning component 500 cleaning the photovoltaic panel 600. It also uses wind energy as a power source, which has the effect of energy saving and environmental protection.

[0058] In some embodiments, refer to Figure 4 , Figure 5 and Figure 6 The cleaning assembly 500 includes a cleaning component 510 and an elastic component 520. The cleaning rod 200 has an installation groove 211. The cleaning component 510 is slidably disposed on the installation groove 211. The cleaning component 510 is used to clean the photovoltaic panel 600. The elastic component 520 is disposed in the installation groove 211 and connected to the cleaning component 510 to push the cleaning component 510 out of the installation groove 211.

[0059] The mounting groove 211 is formed at the bottom of the mounting part 210. The cleaning member 510 is slidably connected to the mounting groove 211 in the vertical direction. The cleaning member 510 is partially exposed outside the mounting groove 211 and contacts the photovoltaic panel 600 to clean the photovoltaic panel 600. The elastic member 520 is provided in the mounting groove 211 and connected to the cleaning member 510 to push the cleaning member 510 partially out of the cleaning groove.

[0060] By adopting the above technical solution, the cleaning component 510 maintains contact with the photovoltaic panel 600 during reciprocating movement. However, there is a certain protrusion of the mounting frame at the end of the photovoltaic panel 600, which is not conducive to the movement of the cleaning component 510 and is prone to damage. In this embodiment, when the cleaning component 510 moves to the protrusion of the mounting frame, the cleaning component 510 can compress the elastic member 520 to shrink the cleaning component 510 into the mounting groove 211, reducing the impact of the mounting frame protrusion on the cleaning component 510. When it moves onto the photovoltaic panel 600, the elastic member 520 will pop the cleaning component 510 out, so that the cleaning component 510 always maintains contact with the photovoltaic panel 600 to achieve a good cleaning effect.

[0061] In some embodiments, refer to Figure 5 The elastic element 520 includes a telescopic rod 521 and a spring 522. The spring 522 is disposed inside the telescopic rod 521 to drive the telescopic rod 521 to extend. One end of the telescopic rod 521 is connected to the mounting groove 211, and the other end is connected to the cleaning element 510.

[0062] Specifically, multiple elastic elements 520 are provided, wherein one end of the telescopic rod 521 is fixed to the inner wall of the mounting groove 211, and the other end of the telescopic rod 521 is detachably connected to the cleaning member 510. The spring 522 is in a compressed state to drive the telescopic rod 521 to have an elongation tendency so as to push out the cleaning member 510.

[0063] For example, refer to Figure 5 The cleaning component 510 includes a first mounting plate 511 and a cleaning sponge 512. The first mounting plate 511 is slidably disposed in the mounting groove 211 and connected to the elastic member 520. The cleaning sponge 512 is disposed on the first mounting plate 511 and extends out of the mounting groove 211 to contact the photovoltaic panel 600.

[0064] The cleaning sponge 512 is fixed on the first mounting plate 511, which is slidably connected in the mounting groove 211. The first mounting plate 511 is detachably connected to the telescopic rod 521 so that part of the cleaning sponge 512 extends out of the mounting groove 211 and contacts the photovoltaic panel 600 to clean the photovoltaic panel 600.

[0065] For example, refer to Figure 6 The cleaning component 510 includes a second mounting plate 513 and a cleaning brush 514. The second mounting plate 513 is slidably disposed in the mounting groove 211 and connected to the elastic member 520. The cleaning brush 514 is disposed on the second mounting plate 513 and extends out of the mounting groove 211 to contact the photovoltaic panel 600.

[0066] The cleaning brush 514 is fixed on the second mounting plate 513, which is slidably connected in the mounting groove 211. The second mounting plate 513 is detachably connected to the telescopic rod 521 so that part of the cleaning brush 514 extends out of the mounting groove 211 and contacts the photovoltaic panel 600 to clean the photovoltaic panel 600.

[0067] The photovoltaic module cleaning device provided in this application embodiment cleans the photovoltaic panel 600 by setting a cleaning rod 200 on the mounting frame 100 and a cleaning component 500 on the cleaning rod 200. Furthermore, by setting a wind cup 300, the wind power drives the wind cup 300 to rotate, which in turn drives a transmission component 400. The transmission component 400 then drives the cleaning rod 200 to slide back and forth on the mounting frame 100, thereby enabling the cleaning component 500 to reciprocate and clean the photovoltaic panel 600. This achieves wind-driven cleaning of the photovoltaic module, reduces dust accumulation on the photovoltaic panel 600, and ensures the normal operation of the photovoltaic module.
