[0031] Embodiment 1:

[0032] Reference Figure 1-6 , a cleaning device for outdoor photovoltaic components, comprising two clamping frames 1, the bottom ends of the adjacent sides of the two clamping frames 1 are fixedly connected with sliding rods 2, the top ends of the adjacent sides of the two clamping frames 1 are clamped with photovoltaic panels 6, an unfolding assembly is connected between the two sliding rods 2, the top side of the left clamping frame 1 is fixedly connected with a sliding frame 7, the inner wall of the sliding frame 7 is rotatably connected with a screw rod 8, the outer wall of the screw rod 8 is threadedly connected with a screw sleeve 9, the rear end of the screw rod 8 is connected with a driving assembly, a plurality of splicing sleeves 12 are arranged on the right side of the screw sleeve 9, a protective sleeve 14 is arranged on the right side of the rightmost splicing sleeve 12, the screw sleeve 9, the splicing sleeve 12 and the protective sleeve 14 are all connected through a splicing assembly, and a cleaning brush is arranged on the bottom side of the splicing sleeve 12; the driving assembly comprises a motor 10, the outer wall of the motor 10 is fixedly connected to the rear side of the sliding frame 7 through a shell, and the driving end of the motor 10 is fixedly connected to the rear end of the screw rod 8;

[0033] Specifically, the device adopts an external design, which is intended to install a cleaning component for outdoor photovoltaic modules that are not designed with a cleaning structure, so that the photovoltaic modules do not need to be replaced with new photovoltaic modules with cleaning components, thereby reducing replacement costs and expenses. The shape of the screw sleeve 9 is consistent with the internal structure of the sliding frame 7, so that when the screw sleeve 9 is displaced by the transmission of the screw rod 8, the screw sleeve 9 will not rotate due to the limitation of the sliding frame 7, thereby ensuring that the screw sleeve 9 and the structure connected to the right end of the screw sleeve 9 are stably displaced. When cleaning the surface of the photovoltaic panel 6, the started motor 10 will drive the screw rod 8 connected to its driving end to rotate, and the rotating screw rod 8 will thread the screw sleeve 9 to displace the screw sleeve 9, and the displaced screw sleeve 9 drives the right end together with the components including the splicing sleeve 12 to displace.

[0034] The unfolding assembly includes two sliding sleeves 3, both of which are slidably connected to the outer wall of the slide rod 2, and a connecting rod 4 is connected between the sliding sleeves 3 at both ends, and the two connecting rods 4 cross each other, and the sides of the two connecting rods 4 that are close to each other are connected by rotation, and the sides of the two sliding sleeves 3 that are separated are provided with springs 5, and the springs 5 ​​are sleeved on the outer wall of the slide rod 2; one end of the connecting rod 4 is rotatably connected to the sliding sleeve 3 at the left end, and the other end of the connecting rod 4 is rotatably connected to the sliding sleeve 3 at the right end;

[0035] Specifically, one end of the spring 5 is connected to the sliding sleeve 3, and the other end is connected to the end of the sliding rod 2, so that when the sliding sleeve 3 is displaced, the traction spring 5 is deformed. The device body can be unfolded and stored by the unfolding and storage of the connecting rod 4, so that the device can be adapted to photovoltaic panels 6 of different sizes and can be conveniently transported and stored. When installing the cleaning device, the spacing of the clamping frame 1 is increased by pulling apart the clamping frame 1, and at the same time, the middle ends of the two connecting rods 4 rotate with each other, the angle of the intersection changes, and the sliding sleeves 3 connected at both ends of the connecting rod 4 slide toward each other on the sliding rod 2, the spacing is reduced, and the spring 5 on the side of the sliding sleeve 3 is stretched, and the two clamping frames 1 are placed on the back of the photovoltaic panel 6 of the photovoltaic assembly. At this time, the clamping frame 1 is released, the spring 5 is reset, the sliding sleeve 3 is pulled, and the stressed sliding sleeve 3 pulls the connecting rod 4, so that the clamping frame 1 is pulled by the connecting rod 4, and the two ends of the photovoltaic panel 6 are firmly clamped.

[0036] Embodiment 2:

[0037] As one of the optimized structural designs for Example 1, Figure 1 , Figure 5 and Figure 6As shown, the splicing assembly includes a plurality of buckles 11, which are respectively fixedly connected to the right side of the screw sleeve 9 and the right side of the splicing sleeve 12, and the left side of the splicing sleeve 12 and the left side of the protective sleeve 14 are both provided with a plug-in cavity, and the inner wall of the plug-in cavity is provided with a card slot 13 on both the front and rear sides, and the right end of the buckle 11 is provided with a protrusion on both the front and rear sides, and the buckle 11 is plugged into the inside of the plug-in cavity, and the buckle 11 is connected with the card slot 13 through the protrusion;

[0038] Specifically, through modular design, the structure of the cleaning part can be adapted to different sizes of photovoltaic panels 6, and a cleaning long-handled brush suitable for the length of the photovoltaic panel 6 can be spliced. The buckle 11 has a certain elasticity, and the size of the slot 13 is adapted to the size of the raised portion of the buckle 11, so that the raised portion of the buckle 11 can be inserted into the slot 13. After the device is clamped on the photovoltaic panel 6, a certain number of splicing sleeves 12 are selected, and these splicing sleeves 12 are plugged into each other. The splicing sleeve 12 at the far left is plugged into the right end of the screw sleeve 9, and the splicing sleeve 12 at the far right is plugged into the protective sleeve 14. During the plugging process, the buckle 11 will be plugged into the plug-in cavity. The buckle 11 is squeezed at the opening of the plug-in cavity and deformed to gather in the middle. The buckle 11 is pushed into the interior of the plug-in cavity until the raised part of the buckle 11 reaches the position of the slot 13. At this time, the raised part of the buckle 11 is reset according to the elasticity of the buckle 11 and is inserted into the slot 13, and then the buckle 11 is plugged into the plug-in cavity, so that the components including the splicing sleeve 12 connected to the buckle 11 and the plug-in cavity are connected to each other, so that they are combined into a long-handled brush for cleaning the surface of the photovoltaic panel 6.

[0039] The cleaning brush includes a brush 16, which is fixedly connected to the middle end of the bottom side of the splicing sleeve 12, and scraping strips 15 are arranged on both the front and rear sides of the brush 16, and the top side of the scraping strip 15 is fixedly connected to the bottom side of the splicing sleeve 12;

[0040] Specifically, when cleaning the photovoltaic panel 6, the displaced screw sleeve 9 drives the right end together with the components including the splicing sleeve 12 to displace, so that the brush 16 on the bottom side of the splicing sleeve 12 cleans soft dirt such as dust. The scraper bar 15 is made of harder rubber. The scraper bar 15 is used to clean hard dirt or scrape off liquid dirt while avoiding damage to the surface of the photovoltaic panel 6, thereby extending the service life of the photovoltaic panel 6.

[0041] Working principle: When installing the cleaning device, the spacing of the clamping frames 1 is increased by pulling apart the clamping frames 1, and at the same time, the middle ends of the two connecting rods 4 rotate relative to each other, the angle of intersection changes, and the sliding sleeves 3 connected at both ends of the connecting rod 4 slide toward each other on the sliding rod 2, the spacing is reduced, and the spring 5 on the side where the sliding sleeve 3 is separated is stretched, and the two clamping frames 1 are placed on the back of the photovoltaic panel 6 of the photovoltaic module. At this time, the clamping frames 1 are released, the spring 5 is reset, and the sliding sleeve 3 is pulled. The stressed sliding sleeve 3 pulls the connecting rod 4, so that the clamping frames 1 are pulled by the connecting rod 4, and the two ends of the photovoltaic panel 6 are firmly clamped. Then, according to the spacing from the clamping frame 1 at the left end to the clamping frame 1 at the right end, a certain number of splicing sleeves 1 are selected. 2. These splicing sleeves 12 are plugged into each other, the splicing sleeve 12 at the far left is plugged into the right end of the screw sleeve 9, and the splicing sleeve 12 at the far right is plugged into the protective sleeve 14. During the plugging process, the buckle 11 will be plugged into the plug-in cavity. The buckle 11 is squeezed at the opening of the plug-in cavity and deformed to gather toward the middle. The buckle 11 is pushed into the inside of the plug-in cavity until the raised part of the buckle 11 reaches the position of the slot 13. At this time, the raised part of the buckle 11 is reset according to the elasticity of the buckle 11 and is inserted into the slot 13, thereby plugging the buckle 11 into the plug-in cavity, so that the components including the splicing sleeve 12 connected to the buckle 11 and the plug-in cavity are connected to each other, so that they are combined into a long-handled brush for cleaning the surface of the photovoltaic panel 6. When cleaning the surface of the photovoltaic panel 6, the started motor 10 will drive the screw 8 connected to its driving end to rotate, and at the same time, the rotating screw 8 threadably drives the screw sleeve 9 to move the screw sleeve 9. The displaced screw sleeve 9 drives the right end together with the components including the splicing sleeve 12 to move, so that the brush 16 on the bottom side of the splicing sleeve 12 cleans soft dirt such as dust, and the scraper 15 cleans hard dirt or scrapes off liquid dirt.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
