Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic panel cleaning, and specifically relates to a photovoltaic panel cleaning machine. Background Art

[0002] The existing photovoltaic panel cleaning robots are automated devices specifically designed to clean the dust, dirt and other impurities on the surface of photovoltaic panels. These robots can improve the power generation efficiency of photovoltaic power stations because clean photovoltaic panels can better absorb sunlight and thus generate more electricity. Among them, the rail-mounted photovoltaic cleaning robots rely on the photovoltaic panel frame and are mounted on the photovoltaic panels for cleaning.

[0003] Chinese Patent with application number CN202120606093.8 discloses a photovoltaic panel cleaning robot, including a housing. A photovoltaic panel is fixedly arranged on the front end face of the housing. A brush roller is rotatably installed at the rear end of the housing through a bearing seat. The brush roller makes a rotational motion through a brush motor. Power wheels are rotatably installed on both sides of the brush roller. There are four power wheels, which are distributed on both sides of the two ends of the brush roller. The two power wheels on the same side of the brush roller are connected by a connecting shaft, and the connecting shaft is rotatably connected with the housing. The utility model relates to the technical field of photovoltaic panel processing, and specifically relates to a photovoltaic panel cleaning robot.

[0004] The above existing technology drives the brush roller to rotate automatically for cleaning through a brush motor, without manual operation and without using water resources. The self-used energy is supplied by the photovoltaic power generation carried by itself. However, in the actual use process, after cleaning with the brush roller, some dust is likely to adhere to its bristles, resulting in a gradual decrease in the cleaning efficiency of the brush roller. The dust on the bristles may cause the brush roller to be unable to effectively contact and remove the dust on the target surface or the dust on itself may cause secondary pollution to the photovoltaic panel during the next use, thus affecting the cleaning effect and reducing the cleaning quality.

[0005] In view of this, the present utility model is specifically proposed. Summary of the Utility Model

Detailed implementation manners

[0031] Now, the present utility model will be further described in detail with reference to the drawings.

[0032] Please refer to Figure 1-7 As shown, in this embodiment, a photovoltaic panel cleaning machine is provided, which includes an outer frame 1. A photovoltaic panel body 2 is installed on the upper side of the outer frame 1. A U-shaped cleaning frame 3 is slidably fitted on the outer frame 1. Driving grooves 4 are opened on both sides of the inner wall of the U-shaped cleaning frame 3. Two cooperating driving wheels 5 are rotatably fitted on the inner walls of the driving grooves 4. Driving motors 6 cooperating with the driving wheels 5 are fixedly connected to the lower sides of the U-shaped cleaning frame 3 respectively;

[0033] A dust discharge port 7 is opened on one side of the outer frame 1. A cleaning groove 8 is opened on the upper side of the inner wall of the U-shaped cleaning frame 3. A cleaning motor 9 is fixedly connected to one side of the inner wall of the cleaning groove 8. The output end of the cleaning motor 9 is fixedly connected to a cleaning brush roller 10. A blowing plate 11 is fixedly connected to the upper side of the inner wall of the cleaning groove 8. The blowing plate 11 is a hollow plate, and a plurality of air outlet holes are opened on the lower side of the hollow plate. When there is a certain air pressure in the hollow plate, its gas will be ejected from the plurality of air outlet holes. A blowing groove 12 is opened on one side of the U-shaped cleaning frame 3. A micro blowing pump 13 cooperating with the blowing plate 11 is fixedly connected to the lower side of the inner wall of the blowing groove 12. A flicking component 14 is arranged on the inner wall of the dust discharge port 7.

[0034] An application in one aspect of this embodiment is as follows: When in use, when it is necessary to clean the photovoltaic panel body 2, first, the two driving motors 6 can be started simultaneously to drive the corresponding two driving wheels 5 to rotate. By the contact between the driving wheels 5 and both sides of the outer frame 1, the U-shaped cleaning frame 3 is moved. During the movement, the cleaning motor 9 is started to drive the cleaning brush roller 10 to rotate, so that the cleaning brush roller 10 can normally clean the upper side of the photovoltaic panel body 2;

[0035] After the cleaning is completed, the driving motor 6 is rotated in the reverse direction to drive the driving wheel 5 to reset the U-shaped cleaning frame 3. After the reset, the micro blowing pump 13 is started to blow air into the blowing plate 11. The output end of the micro blowing pump 13 penetrates into the interior of the blowing plate 11. Then, the cleaning motor 9 is started to flip the cleaning brush roller 10, and the cleaning brush roller 10 is blown to fall from the dust discharge port 7, so as to clean the cleaning brush roller 10, realizing automatic cleaning during the intermittent period of the cleaning brush roller 10, without manual intervention, saving manpower and time, and improving the overall working efficiency;

[0036] When the cleaning brush roller 10 rotates, it contacts the cleaning brush roller 10 through the rubber rod 142 on the support plate 141. A slight "flapping" or "sweeping" effect will be generated between the rotational movement of the bristles and the rubber rod 142. This effect can help loosen and bounce up the dust particles adhering to the surface. Subsequently, due to the continuous rotation of the brush roller and the elasticity of the bristles, these dust particles will be swept off or bounced away from the surface, thus achieving the cleaning purpose and further realizing the cleaning effect of the cleaning brush roller 10. The rubber rod 142 is made of soft rubber material and will not affect the movement of the U-shaped cleaning frame 3 above the dust outlet 7.

[0037] By setting the micro air blowing pump 13, after the cleaning is completed, it can be realized that by blowing air into the inside of the air blowing plate 11 and then the gas is ejected from top to bottom, the rotating cleaning brush roller 10 is blown, so that the dust adsorbed on the cleaning brush roller 10 after cleaning is discharged from the dust outlet 7, realizing automatic cleaning without manual intervention, saving manpower and time, and improving the overall work efficiency.

[0038] By setting the rubber rod 142, when the cleaning brush roller 10 rotates, through the contact between the rubber rod 142 and the cleaning brush roller 10, and the bristles on the cleaning brush roller 10 are slapped, so that they are swept off or bounced away from the surface, thus achieving the cleaning purpose and further improving the cleaning effect of the cleaning brush roller 10.

[0039] As Figure 3 and Figure 4 and Figure 7 As shown in [relevant figures], the dust bouncing-off assembly 14 includes a support plate 141 fixedly connected to the inner wall of the dust outlet 7 and a plurality of rubber rods 142 fixedly connected to the upper side of the support plate 141. The rubber rods 142 are in contact with the cleaning brush roller 10. The rubber rod 142 is made of soft rubber material. When the U-shaped cleaning frame 3 moves, the rubber rod 142 will produce a bending effect. When the lower side of the U-shaped cleaning frame 3 overlaps with the dust outlet 7, the rubber rod 142 will rebound and reset.

[0040] As Figure 2 and Figure 7 As shown in [relevant figures], a sealing gasket 15 is fixedly connected to the upper side of the outer frame 1. The upper side of the sealing gasket 15 is in contact with the upper side of the inner wall of the U-shaped cleaning frame 3. By contacting the inside of the U-shaped cleaning frame 3 through the sealing gasket 15, the gap between the U-shaped cleaning frame 3 and the photovoltaic panel body 2 is sealed, which can reduce the situation of secondary pollution of the photovoltaic panel body 2 by dust when cleaning the dust.

[0041] As Figure 1 and Figure 2As shown, one side of the U-shaped cleaning frame 3 is fixedly connected with a dust-proof net 16 located on one side of the blowing groove 12. A plurality of screws are installed between the dust-proof net 16 and the U-shaped cleaning frame 3. The dust-proof net 16 is used for dust prevention in the blowing groove 12, and the plurality of screws improve the convenience of disassembly.

[0042] As Figure 1 and Figure 2 shown, a U-shaped clamp 17 is fixedly connected to the lower side of the U-shaped cleaning frame 3. A limit opening 18 matching the U-shaped clamp 17 is opened on the lower side of the outer frame 1. When the U-shaped cleaning frame 3 moves, the U-shaped clamp 17 can limit the U-shaped cleaning frame 3 in the limit opening 18.

[0043] As Figure 2 shown, a micro photovoltaic panel 19 is fixedly connected to the upper side of the U-shaped cleaning frame 3. A control cabinet 20 matching the micro photovoltaic panel 19 is fixedly connected to the upper side of the U-shaped cleaning frame 3. The control cabinet 20 is matched with the driving motor 6 and the cleaning motor 9. The micro photovoltaic panel 19 has its own battery and is interconnected with the control cabinet 20 through a photovoltaic inverter. The control cabinet 20 controls the internal driving motor 6 and cleaning motor 9, and they are all common matching electrical components on the market.

[0044] As Figure 5 and Figure 6 shown, sprockets 21 are fixedly connected to both of the two driving wheels 5. A chain 22 is arranged between the two sprockets 21. When the driving motor 6 drives one of the driving wheels 5 to rotate, through the action of the chain 22 on the two sprockets 21, the two corresponding driving wheels 5 can rotate in the same direction and in equal proportion.

[0045] The present utility model is not limited to the above embodiments. Anyone should know that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, all fall within the protection scope of the present utility model. The technologies, shapes, and structures not described in detail in the present utility model are all well-known technologies.
