[0002] When cleaning photovoltaic panels, some use telescopic rods equipped with motors and cleaning brushes for manual cleaning. Since there are large gaps between each photovoltaic panel, these cleaning methods require manual movement of the cleaning equipment to the photovoltaic panel. For large-area matrix photovoltaic power stations, the manual labor intensity is high, time-consuming and labor-intensive, and the cleaning efficiency is low. Some use a combination of drones and rotating brushes to clean photovoltaic panels. Although this can reduce the intensity of manual labor, the rotating brush cannot make strong contact with the photovoltaic panel, and the cleaning effect is poor for sundries on the photovoltaic panel that are difficult to clean, such as bird droppings. Therefore, it is necessary to provide a cleaning device that is both labor-saving and has good cleaning effects.

[0028] The present invention is further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0029] See also Figure 1-4The present invention provides a technical solution: a photovoltaic panel cleaning device, comprising a flying device 1, an identification device 2 electrically connected to a control system on the flying device 1, and the flying device 1 is a drone in the prior art. Photovoltaic panels are generally fixed to the ground through a bracket. Photovoltaic panels will be installed in large numbers according to the site and actual needs. Photovoltaic panels are mostly arranged in rows, and each row includes a plurality of photovoltaic panels connected end to end and arranged in sequence, and the inclination angle with the bracket is the same. The above is the prior art and will not be repeated here. A fixing frame 3 is fixed to the end of the flying device 1 away from the wing by bolts. The fixing frame 3 is a rectangular frame structure, and a reinforcing rod with an integral structure and a "cross" structure is arranged in the middle of the fixing frame 3. Positioning mechanisms for placing along two opposite edges of the photovoltaic panel are arranged at the four corners of the fixing frame 3. The positioning mechanism includes a left rod 5 and a right rod 6 arranged at the two ends of the fixing frame 3. The left rod 5 and the right rod 6 are both electric telescopic rods in the prior art, and the electric telescopic rod is electrically connected to the power supply through the drone control system. Left rods 5 are arranged at the two corner positions of one end of the fixing frame 3. There are two left rods 5 and they are symmetrically arranged about the center line of the fixing frame 3. The left rod 5 is hingedly connected to the fixing frame 3 through an axis and a vertical plate. The vertical plate is bolted to the fixing frame 3. There are two vertical plates and they are symmetrically arranged about the left rod 5. One end of the left rod 5 is clamped with an axis that is rotatably connected to the vertical plate. The end of the left rod 5 away from the fixing frame 3 extends to the outside of the fixing frame 3 and is hingedly connected to a swing rod 12. The cross section of the swing rod 12 is an "L"-shaped structure. A rotating shaft for rotatably connecting the swing rod 12 is clamped on the fixing frame 3. The rotating shaft protrudes from the surface of the fixing frame 3. The swing rod 12 is provided with a ring sleeve that is integrally structured with it and used in conjunction with the rotating shaft. There are two ring sleeves and they are symmetrically arranged about the center line of the swing rod 12. The left rod 5 is tilted with the fixing frame 3 under normal conditions, forming a structure in which the left rod 5 is extended or shortened, driving the swing rod 12 to swing around the rotating shaft. The right rod 6 is fixed by bolts at the two corner positions of one end of the fixing frame 3 away from the left rod 5. There are two right rods 6 and they are symmetrically arranged about the center line of the fixing frame 3. The end of the right rod 6 away from the fixing frame 3 is bolted with a connecting rod 7, which is in an "L" shape. The right rod 6 is arranged perpendicular to the connecting rod 7. The end of the swing rod 12 and the connecting rod 7 away from the fixing frame 3 is provided with a clamping wheel 8 fixed to the side of the photovoltaic panel, and the clamping wheel 8 is in a conical structure. After the flying device 1 is parallel and hovered above the photovoltaic panel to be cleaned, the right rod 6 is extended or shortened to drive the connecting rod 7 and the clamping wheel 8 to contact an edge of the photovoltaic panel, and the left rod 5 is extended or shortened to drive the swing rod 12 to rotate a set angle, and then the two connecting rods 7 and the clamping wheels 8 on the two swing rods 12 are fixed along the two opposite edges of the photovoltaic panel. A walking mechanism is provided at one end of the positioning mechanism away from the fixed frame 3, and the walking mechanism includes a motor 10 that drives the clamping wheel 8 to rotate. A motor is provided at one end of the rocker arm 12 and the connecting rod 7 away from the fixed frame 3, and the rocker arm 12 and the motor 10 on the connecting rod 7 are fixed by mounting seat screws.The connecting rod 7 and the rocker 12 are both provided with circular holes penetrating through their respective thickness directions and for the output shaft of the motor 10 to pass through. The output shaft of the motor 10 is key-connected with the clamping wheel 8, and a rubber layer for increasing friction is glued to the outer surface of the clamping wheel 8. The motor 10 is electrically connected to the power supply through the control system, forming a structure in which the motor 10 rotates and drives the fixing frame 3 to move along the length direction of the photovoltaic panel. A cleaning mechanism is provided on the side of the fixing frame 3 away from the flying device 1, forming a structure in which the walking mechanism drives the fixing frame 3 and the cleaning mechanism to move along the photovoltaic panel, and the photovoltaic panel cleans the photovoltaic panel under the action of the cleaning mechanism.

[0030] In one embodiment, according to the accompanying drawings of the specification Figure 2 As shown, the cleaning mechanism includes a cleaning brush 11, which belongs to the prior art. The cleaning brush 11 is a hollow cylindrical structure and is sleeved outside the rotating shaft. The cleaning brush 11 is glued to the rotating shaft. A placement box 13 for rotating the connecting shaft is fixed on the fixing frame 3 by screws. The placement box 13 is a hollow and-shaped structure. The cleaning brush 11 is arranged along the length direction of the placement box 13. There are two cleaning brushes 11 and they are symmetrically arranged about the center line of the placement box 13. A driving motor 14 for driving the cleaning brush 11 to rotate is arranged at one end of the placement box 13. The driving motor 14 is fixed to the side wall of the placement box 13 by a mounting seat bolt, forming a structure in which pollutants are cleaned under the action of the cleaning brush 11 driven by the driving motor 14. The cleaning brush 11 is arranged obliquely with the fixing frame 3, and the placement box 13 is arranged parallel to the cleaning brush 11. The obliquely arranged cleaning brush 11 facilitates the discharge of debris after cleaning the photovoltaic panel under the dual action of gravity and the cleaning brush 11. The placement box 13 is provided with a groove which is recessed into itself and is used for placing the fixing frame 3. The length of the placement box 13 and the cleaning brush 11 is greater than the length of the fixing frame 3, so that after the positioning mechanism is fixed to the two opposite edges of the photovoltaic panel by means of the clamping wheels 8 on the two connecting rods 7 and the two rocker arms 12, the cleaning brush 11 can fully cover the photovoltaic panel in the width direction and move in the length direction of the photovoltaic panel to clean the entire photovoltaic panel.

[0031] In one embodiment, according to the accompanying drawings of the specification Figure 4As shown, the fixed frame 3 is provided with a running wheel 15, and there are two running wheels 15 and they are symmetrically arranged about the center line of the fixed frame 3. The running wheel 15 is connected to the fixed frame 3 through an adjusting rod 16, and the adjusting rod 16 and the running wheel 15 are both bolted. The adjusting rod 16 includes a base rod bolted to the fixed frame 3, and a sliding hole is provided in the base rod along its length direction and at a position located at the center line thereof, and an extension rod is slidably connected to the sliding hole, and the ends of the extension rod and the base rod that are away from each other are glued with a limiting ring, and a spring sleeved on the outer wall of the base rod and the extension rod is bolted between the two limiting rings. When forming a cleaning heavy pollution area, the flying device 1 drives the fixed frame 3 to move downward in the direction perpendicular to the photovoltaic panel, and the positioning mechanism makes an adaptive adjustment to shorten the distance between the cleaning brush 11 and the photovoltaic panel to be cleaned, thereby increasing the structure of the cleaning force. When the flying device 1 drives the fixing frame 3 to move downward in the direction perpendicular to the photovoltaic panel, the connecting rod 7 and the rocker arm 12 drive the clamping wheel 8 to move downward synchronously, and the right rod 6 retracts a set distance under the action of the control system, and the two connecting rods 7 drive the clamping wheel 8 to move toward the side close to the photovoltaic panel to be cleaned; the left rod 5 extends a set distance under the action of the control system, and the two rocker arms 12 drive the clamping wheel 8 to move toward the side close to the photovoltaic panel to be cleaned; the four clamping wheels 8 re-fix the two opposite sides of the photovoltaic panel to be cleaned. At this time, the contact area between the cleaning brush 11 and the photovoltaic panel to be cleaned is increased, and the cleaning force is also enhanced, which can better clean up the debris on the photovoltaic panel that is not easy to clean.

[0032] Instructions for use: When in use, the flying device drives the fixed frame to move to the top of the photovoltaic panel to be cleaned. The flying device adjusts the tilt angle to be parallel to the photovoltaic panel through the identification device and hovers;

[0033] The right rod feeds back the data of the photovoltaic panel to be cleaned detected by the identification device to the control system, and the control system controls the power supply to supply power to the right rod, and ensures that the right rod is extended by a set distance until the clamping wheel on the connecting rod contacts the side of the photovoltaic panel to be cleaned;

[0034] The control system controls the power supply to the left rod, the left rod extends a set distance, and the swing rod drives the clamping wheel to rotate under the action of the left rod until the four clamping wheels clamp the two opposite sides of the photovoltaic panel to be cleaned;

[0035] The driving motor is connected to the power supply under the control of the control system, and the driving motor drives the cleaning brush in the placement box to rotate. The debris is separated from the photovoltaic panel under the action of the cleaning brush and falls through an edge of the photovoltaic panel under the dual action of the gravity of the debris and the push of the cleaning brush, thereby achieving the removal of the debris;

[0036] The motor is powered by the control system, and the clamping wheel rotates, thereby driving the fixing frame and the cleaning brush to move along the length direction of the photovoltaic panel. After a row of photovoltaic panels is cleaned, the above action is repeated until all photovoltaic panels are cleaned;

[0037] When the cleaning process encounters heavy dirt that is difficult to clean, the identification device will detect that there are still debris attached to the photovoltaic panel in the cleaned area. At this time, the motor reverses under the control system to ensure that the fixed frame drives the cleaning brush to move to the edge of the heavy dirt. The flying device drives the fixed frame to move down a set distance in the direction perpendicular to the photovoltaic panel, and the connecting rod and the swing rod drive the clamping wheel to move down synchronously. The right rod retracts the set distance under the control system, and the two connecting rods drive the clamping wheels to move toward the side close to the photovoltaic panel to be cleaned; the left rod extends the set distance under the control system, and the two swing rods drive the clamping wheels to move toward the side close to the photovoltaic panel to be cleaned; the four clamping wheels re-fix the two opposite sides of the photovoltaic panel to be cleaned, and the motor rotates forward under the control system. When the distance between the cleaning brush and the photovoltaic panel to be cleaned is shortened and the contact area between the cleaning brush and the photovoltaic panel to be cleaned is increased, the cleaning continues, and the motor drives the cleaning brush to move to the other edge of the heavy dirt. The right rod extends the set distance under the control system, and the left rod shortens the set distance under the control system. The flying equipment drives the fixed frame to move up the set distance in the direction perpendicular to the photovoltaic panel, and ensures that the four clamping wheels re-fix the two opposite sides of the photovoltaic panel to be cleaned. The motor continues to drive the cleaning brush to clean the photovoltaic panel under the control system.

[0038] The present invention provides a fixing frame on the flying device, a positioning mechanism fixed to the side of the photovoltaic panel to be cleaned and a walking mechanism moving along the edge of the photovoltaic panel on the fixing frame, and a cleaning mechanism on the side of the fixing frame away from the flying device, so that the labor intensity is greatly reduced when cleaning the photovoltaic panel. The setting of the walking wheel with adjustable length connected to the fixing frame and the cooperation of the identification device electrically connected to the control system of the flying device can increase the cleaning force at the heavily contaminated position, so as to facilitate the cleaning of the sundries that are difficult to clean; the right rod is fixedly connected to the fixing frame, so that the flying mechanism can adjust the length of the walking wheel after it approaches the position of the photovoltaic panel to be cleaned. The length of the right rod is adjusted to realize the rapid fixation of the clamping wheel on one side of the photovoltaic panel, the swing arm is hinged to the edge of the fixing frame, and one end of the swing arm is hinged to the left rod, so that the left rod can be extended or retracted to a set length under the action of the control system to drive the swing arm to rotate, thereby realizing the fixation of the clamping wheel on the other side of the photovoltaic panel; the setting of the clamping wheel with a conical structure on the walking mechanism is convenient for better movement along the photovoltaic panel, and the setting of the motor electrically connected to the control system provides power for the movement of the cleaning mechanism; the inclined cleaning brush is convenient for the discharge of debris after cleaning the photovoltaic panel under the dual action of gravity and the cleaning brush.

[0039] The present invention has been described in detail above through specific implementation modes and embodiments, but these do not constitute limitations of the present invention. Without departing from the principles of the present invention, those skilled in the art may also make many variations and improvements, which should also be regarded as the protection scope of the present invention.
