Detailed Implementation

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0022] Please refer to Figure 1 As those skilled in the art will understand, the photovoltaic panel 10 is generally installed at an angle relative to the mounting surface, which refers to a horizontal surface such as a rooftop or the ground. In this embodiment, the upper surface 11 of the photovoltaic panel 10 refers to the surface of the photovoltaic panel 10 facing the sun, that is, the surface of the photovoltaic panel 10 that absorbs light energy. In this embodiment, the photovoltaic panel 10 includes a first end and a second end arranged opposite to each other along a first direction, and in the direction of gravity, the first end of the photovoltaic panel 10 is higher than the second end of the photovoltaic panel 10. More specifically, the first end of the photovoltaic panel 10 refers to the end of the photovoltaic panel 10 that is farther from the mounting surface, and the second end of the photovoltaic panel 10 refers to the end of the photovoltaic panel 10 that is closer to the mounting surface. In this embodiment, the side surface 12 of the first end of the photovoltaic panel 10 refers to the surface where the first end of the photovoltaic panel 10 connects to the upper surface 11 of the photovoltaic panel 10.

[0023] Please refer to Figures 1 to 4 The photovoltaic panel cleaning device provided in this application embodiment is used to clean foreign objects from a photovoltaic panel 10. The photovoltaic panel 10 includes a first end and a second end that are opposite each other along a first direction. In the direction of gravity, the first end of the photovoltaic panel 10 is higher than the second end of the photovoltaic panel 10. The photovoltaic panel cleaning device includes a first rolling component 100, a second rolling component 200, and a cleaning component 300. The first rolling component 100 is disposed at the first end of the photovoltaic panel 10, and the second rolling component 200 is disposed at the second end of the photovoltaic panel 10.

[0024] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The cleaning component 300 includes a mounting frame 310, a chain 320, a first sprocket 330, a second sprocket 340, and a cleaning component 350. A first rolling component 100 and a second rolling component 200 are respectively fixed to opposite ends of the mounting frame 310. The first sprocket 330 is located on the side of the mounting frame 310 near the first rolling component 100, and the second sprocket 340 is located on the side of the mounting frame 310 near the second rolling component 200. The chain 320 is engaged with the first sprocket 330 and the second sprocket 340. The cleaning component 350 is fixed to the side of the chain 320 facing the upper surface 11 of the photovoltaic panel 10. The first sprocket 330 and the second sprocket 340 can drive the chain 320 to rotate so that the cleaning component 350 can clean the upper surface 11 of the photovoltaic panel 10. The rotation trajectory of the cleaning component 350 is parallel to the upper surface 11 of the photovoltaic panel 10.

[0025] refer to Figure 4 The mounting bracket 310 is provided with dust discharge ports 311 at both opposite ends along the first direction. The dust discharge ports 311 extend out of the photovoltaic panel 10 along the first direction and face the photovoltaic panel 10. The rotation trajectory of the cleaning component 350 passes through the two dust discharge ports 311.

[0026] Please refer to Figure 2 and Figure 4 In this embodiment, the first sprocket 330 and the second sprocket 340 are both parallel to and spaced apart from the upper surface 11 of the photovoltaic panel 10. That is, the rotation surfaces of the first sprocket 330 and the second sprocket 340 are parallel to the upper surface 11 of the photovoltaic panel 10. The chain 320 meshes with the first sprocket 330 and the second sprocket 340; therefore, the plane containing the rotation trajectory of the chain 320 is also parallel to the upper surface 11 of the photovoltaic panel 10. Those skilled in the art will understand that while the plane containing the rotation trajectory of the chain 320 is parallel to the upper surface 11 of the photovoltaic panel 10 in this application, in reality, the chain 320 may have some deviation due to gravity or installation errors. That is, in practice, absolute parallelism will not occur.

[0027] In this embodiment, the cleaning component 350 is fixedly connected to the side of the chain 320 facing the upper surface 11 of the photovoltaic panel 10. Obviously, the side of the cleaning component 350 facing the upper surface 11 of the photovoltaic panel 10 should be in contact with the upper surface 11 of the photovoltaic panel 10, so that when the cleaning component 350 rotates with the chain 320, the cleaning component 350 can clean the dust, snow and other debris on the upper surface 11 of the photovoltaic panel 10. As the cleaning component 350 rotates with the chain 320 to clean the upper surface 11 of the photovoltaic panel 10, when the cleaning component 350 rotates to the dust discharge port 311, since the dust discharge port 311 extends beyond the photovoltaic panel 10 in the first direction, the dust cleaned by the cleaning component 350 will also be driven by the cleaning component 350 to a position extending beyond the photovoltaic panel 10 in the first direction. At this time, under the action of gravity, the dust or snow cleaned by the cleaning component 350 will fall from the dust discharge port 311 to the ground, thus preventing dust, snow and other foreign objects from being stirred up and falling back onto the photovoltaic panel 10, thereby improving the cleaning effect.

[0028] Those skilled in the art will also understand that there can be multiple cleaning components 350, which are spaced apart on the chain 320. The specific number of cleaning components 350 can be set by those skilled in the art according to the actual situation, and this application embodiment does not make a specific limitation.

[0029] Please refer to Figure 2 and Figure 3 In some embodiments, the mounting frame 310 includes a first support beam 312, a second support beam 313, a first fixing plate 314, and a second fixing plate 315. The first support beam 312 and the second support beam 313 are arranged parallel and spaced apart. The photovoltaic panel 10 extends from opposite ends of the first support beam 312 along the first direction and is fixedly connected to the first rolling assembly 100 and the second rolling assembly 200. The photovoltaic panel 10 extends from opposite ends of the second support beam 313 along the first direction and is fixedly connected to the first rolling assembly 100 and the second rolling assembly 200. The first mounting bracket 310 consists of a first rolling assembly 100 and a second rolling assembly 200. A first fixed plate 314 is fixedly connected to a first support beam 312 and a second support beam 313, with the first fixed plate 314 located on the side closer to the first rolling assembly 100. A first sprocket 330 is located on the side of the first fixed plate 314 facing the photovoltaic panel 10. A second fixed plate 315 is fixedly connected to the first support beam 312 and the second support beam 313, with the second fixed plate 315 located on the side closer to the second rolling assembly 200. A second sprocket 340 is located on the side of the second fixed plate 315 facing the photovoltaic panel 10. Using the first support beam 312 and the second support beam 313 reduces the weight of the mounting bracket 310, thereby preventing damage to the photovoltaic panel 10 due to excessive weight of the cleaning equipment.

[0030] Those skilled in the art will understand that the photovoltaic panels 10 extend from both ends of the first support beam 312 and the second support beam 313 along the first direction, and the interval between the portions of the first support beam 312 and the second support beam 313 extending out of the photovoltaic panels 10 forms a dust discharge port 311.

[0031] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the mounting frame 310 further includes a first track beam 316 and a second track beam 317. The first track beam 316 is fixedly connected to a first support beam 312, and the second track beam 317 is fixedly connected to a second support beam 313. A first slide rail 3161 is provided on the side of the first track beam 316 facing the photovoltaic panel 10, and the first slide rail 3161 extends through the first track beam 316 along a first direction. A second slide rail 3171 is provided on the side of the second track beam 317 facing the photovoltaic panel 10, and the second slide rail 3171 extends through the second track beam 317 along the first direction. A portion of the chain 320 is located in the first slide rail 3161 and the second slide rail 3171. In this embodiment, by setting the first slide rail 3161 and the second slide rail 3171, the running trajectory of the chain 320 can be ensured to be stable, thereby ensuring the smooth operation of the cleaning component 350 and improving the cleaning effect.

[0032] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the first slide rail 3161 and the second slide rail 3171 each include a receiving cavity 3162 and a clearance cavity 3163 that are interconnected along the direction from the first support beam 312 to the photovoltaic panel 10. The chain 320 includes a first chain piece group 321 and a second chain piece group 322 that are disposed opposite to each other, and a roller group 323 connected between the first chain piece group 321 and the second chain piece group 322. The first chain piece group 321 is located in the receiving cavity 3162 and contacts the bottom wall of the receiving cavity 3162 on the side near the clearance cavity 3163. The roller group 323 extends from the side of the clearance cavity 3163 away from the receiving cavity 3162 and is connected to the second chain piece group 322. The cleaning member 350 is fixedly connected to the side of the second chain piece group 322 away from the first chain piece group 321. With this configuration, the bottom wall of the cavity 3162 can support the weight of the chain 320 and the cleaning component 350, thereby preventing the chain 320 and the cleaning component 350 from falling due to gravity. This ensures that the pressure applied by the cleaning component 350 to the upper surface 11 of the photovoltaic panel 10 is consistent, preventing damage to the photovoltaic panel 10 during the cleaning process and ensuring the service life of the photovoltaic panel 10.

[0033] Those skilled in the art will understand that the first chain link group 321, the second chain link group 322, and the roller group 323 of the chain 320 can be easily disassembled and assembled. Therefore, in the process of installing the chain 320 to the first slide rail 3161, the first sprocket 330, the second slide rail 3171, and the second sprocket 340, the chain 320 can be disassembled first and then installed, which facilitates the installation of the chain 320.

[0034] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the cleaning assembly 300 further includes a connecting plate 360, through which the cleaning component 350 is fixedly connected to the side of the second chain link group 322 opposite to the first chain link group 321. Fixing the cleaning component 350 via the connecting plate 360 ​​facilitates adjustment of its position and installation. Those skilled in the art will understand that the cleaning component 350 may include a brush and a flexible plate, which may be alternately and alternately arranged on the side of the second chain link group 322 opposite to the first chain link group 321. The flexible plate may be made of rubber. The brush removes dust, while the flexible plate removes snow. The simultaneous arrangement of the brush and flexible plate on the second chain link group 322 allows the cleaning device to remove both dust and snow.

[0035] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the photovoltaic panel cleaning device further includes a reinforcing plate 370, which is fixedly connected to the first support beam 312 and the second support beam 313; the first track beam 316 and the second track beam 317 are respectively fixedly connected to the reinforcing plate 370 on the side facing the photovoltaic panel 10. Those skilled in the art will understand that multiple reinforcing plates 370 can be provided, and the multiple reinforcing plates 370 are spaced apart along a first direction. By providing reinforcing plates 370, deformation of the first support beam 312 and the second support beam 313 can be avoided. In this embodiment, the first track beam 316 and the second track beam 317 can also be fixedly connected to the reinforcing plate 370 on the side facing the photovoltaic panel 10, thereby allowing flexible adjustment of the positions of the first track beam 316 and the second track beam 317 to adapt to the rotation trajectory of the chain 320, facilitating installation.

[0036] Please refer to Figure 2 , Figure 3 and Figure 4In some embodiments, the photovoltaic panel cleaning device further includes a drive motor 380, which is fixed to a first fixed plate 314 and used to drive a first sprocket 330, or the drive motor 380 is fixed to a second fixed plate 315 and used to drive a second sprocket 340. Those skilled in the art will understand that hydraulic or pneumatic drives can also be used. In the embodiments of this application, the drive motor 380 can be used to drive either the first sprocket 330 or the second sprocket 340, and this is not limited thereto. Those skilled in the art will also understand that the drive motor 380 can drive the chain 320 to rotate clockwise, such as... Figure 4 As shown, the drive motor 380 can also drive the chain 320 to rotate counterclockwise, but no specific limitation is made in this embodiment.

[0037] In some embodiments, the first rolling component 100 and the second rolling component 200 can move along a second direction on the upper surface 11 of the photovoltaic panel 10 to drive the cleaning component 300 to move along the second direction on the upper surface 11 of the photovoltaic panel 10, the second direction being perpendicular to the first direction. Those skilled in the art will understand that, since the area of ​​the photovoltaic panel 10 is generally large, the cleaning component 350 needs to move along the second direction during the cleaning of the upper surface 11 of the photovoltaic panel 10 to ensure that the cleaning component 350 can completely clean the upper surface 11 of the photovoltaic panel 10. In this embodiment, the movement of the first rolling component 100 and the second rolling component 200 drives the movement of the cleaning component 300, thereby enabling the cleaning component 300 to perform comprehensive cleaning of the upper surface 11 of the photovoltaic panel 10, improving the automation capability of the cleaning equipment.

[0038] In some embodiments, the first rolling assembly 100 includes a first mounting plate 110 and two side wheels 120, and the second rolling assembly 200 includes a second mounting plate 210; the opposite ends of the mounting bracket 310 are respectively fixed to the first mounting plate 110 and the second mounting plate 210; specifically, the opposite ends of the first support beam 312 are respectively fixedly connected to the first mounting plate 110 and the second mounting plate 210, and the opposite ends of the second support beam 313 are respectively fixed to the first mounting plate 110 and the second mounting plate 210.

[0039] Two side wheels 120 are respectively connected to the first mounting plate 110, and both side wheels 120 can roll on the side 12 of the first end of the photovoltaic panel 10. By setting two side wheels 120, the cleaning equipment can be hung on the photovoltaic panel 10 without the need for additional support equipment, making the structure simple and practical.

[0040] The first rolling assembly 100 further includes two first traveling wheels 130, and the second rolling assembly 200 further includes two second traveling wheels 220; the end of the cleaning assembly 300 away from the first mounting plate 110 is fixedly connected to the second mounting plate 210; both first traveling wheels 130 are connected to the first mounting plate 110, and both first traveling wheels 130 can roll along the upper surface 11 of the first end of the photovoltaic panel 10; both second traveling wheels 220 are connected to the second mounting plate 210, and both second traveling wheels 220 can roll along the upper surface 11 of the second end of the photovoltaic panel 10. Those skilled in the art will understand that the two first traveling wheels 130 are located on both sides of the cleaning component 300, and the two second traveling wheels 220 are also located on both sides of the cleaning component 300. More specifically, the interval between the two first traveling wheels 130 is equal to the interval between the two second traveling wheels 220, and one end of the cleaning component 300 is fixed in the middle of the two first traveling wheels 130, and the other end of the cleaning component 300 is fixed in the middle of the two second traveling wheels 220. This arrangement can ensure that the cleaning equipment moves smoothly during movement.

[0041] Of course, both the first traveling wheel 130 and the second traveling wheel 220 can be driven by a drive device so that the first traveling wheel 130 and the second traveling wheel 220 can roll on the upper surface 11.

[0042] The embodiments of this application have been described in detail above. Specific examples have been used in this article to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and central idea of ​​this application.
