[0030] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

[0031] Please refer to Figure 1-12 A drone component for photovoltaic cleaning includes a drone base 1 and arms 2 around the drone base 1, wings 3 are provided at the ends of the arms 2, a cleaning substrate 8 with an adjustable angle is provided under the drone base 1, a cleaning mechanism for cleaning photovoltaic panels 12 is provided in the cleaning substrate 8, and the photovoltaic panels 12 are cleaned by the cleaning mechanism when the drone flies horizontally.

[0032] In the solution of the present invention, an angle adjustment mechanism is provided at the bottom of the drone base 1, and the cleaning substrate 8 is adjusted in angle through the angle adjustment mechanism. The angle adjustment mechanism includes a fixed block 5 fixed to the bottom surface of the drone base 1 and a lifting block 6 on one side of the fixed block 5. A fixed U-shaped rod 51 is provided at the bottom of the fixed block 5, and a lifting U-shaped rod 63 is provided at the bottom of the lifting block 6. Two connecting blocks 7 with holes are provided in the middle of the surface of the cleaning substrate 8. The two connecting blocks 7 with holes are respectively connected to the fixed U-shaped rod 51 and the lifting U-shaped rod 63. The bottom of the connecting block 7 with holes is fixed to the surface of the cleaning substrate 8, and the up and down lifting of the lifting block 6 drives the cleaning substrate 8 to tilt left and right.

[0033] The connection between the holed connecting block 7 and the fixed U-shaped rod 51 and the lifting U-shaped rod 63 is equivalent to a hinge, the holed connecting block 7 is rotatably connected to the fixed U-shaped rod 51, and the holed connecting block 7 and the lifting U-shaped rod 63 are movable and pushed; when the angle of the cleaning substrate 8 needs to be adjusted, it is only necessary to control the lifting and lowering of the lifting block 6; the lifting and lowering of the lifting block 6 can drive the cleaning substrate 8 to achieve angle adjustment, so that the cleaning substrate 8 matches the inclination angle of the photovoltaic panel and improves the cleaning effect.

[0034] Specifically, the fixed block 5 is provided with a vertically erected rack 53 on one side close to the lifting block 6, and T-shaped limit grooves 52 are symmetrically provided on both sides of the rack 53. The lifting block 6 is provided with a slider matched with the T-shaped limit groove 52 on one side close to the fixed block 5, and the lifting block 6 is lifted and lowered along the T-shaped limit groove 52 through the slider. The lifting block 6 is provided with a groove 62 on one side close to the fixed block 5, and a gear matched with the rack 53 is provided in the groove 62. The gear is connected to the output shaft of the motor 61 by transmission, and the lifting block 6 is lifted and lowered when the gear rotates. In other words, the lifting block 6 is matched with the T-shaped limit groove 52 on the fixed block 5 through the slider, and the motor 6 drives the gear to rotate at the same time. When the motor 6 rotates, the gear meshes with the rack 53 to realize the lifting and lowering of the lifting block 6. When the bottoms of the fixed U-shaped rod 51 and the lifting U-shaped rod 63 are flush, the cleaning substrate 8 is set horizontally (such as Fig.10 As shown in FIG. 1 ), when the lifting U-shaped rod 63 extends out of the bottom of the fixed U-shaped rod 51, the cleaning substrate 8 tilts to the left (as shown in FIG. 1 ). Fig.11 As shown in FIG. 1 ), when the lifting U-shaped rod 63 is retracted into the bottom of the fixed U-shaped rod 51, the cleaning substrate 8 tilts to the right (as shown in FIG. 1 ). Fig.12 as shown).

[0035] In this embodiment, the motor 61 is a stepper motor, which can realize the forward and reverse rotation of the gears, thereby driving the lifting block 6 to achieve lifting; in addition, the motor 61 is remotely controlled through a control system, and the control system includes a motor driver, a single-chip microcomputer, a 4G / 5G module, a cloud server and a mobile phone terminal. The motor controller is electrically connected to the single-chip microcomputer and is connected to the cloud server signal through the 4G / 5G module. The mobile phone terminal, the single-chip microcomputer and the 4G / 5G module are connected to the same cloud server; the model of the single-chip microcomputer is STM32.89c51, and the model of the 4G module is G8100.

[0036] When it is necessary to adjust the angle of the cleaning substrate 8, an on command is input to the mobile phone terminal, and the single chip microcomputer and the 4G modular motor controller drive the motor 61 to work. At this time, the motor 61 is running, and after the motor 61 is running, the gear starts to rotate and engages with the rack 53 at the same time, so that the lifting block 6 can be lifted and lowered along the T-shaped limit groove 52; since the lifting U-shaped rod 62 is fixed at the bottom of the lifting block 6, the lifting block 6 will drive the lifting U-shaped rod 62 to move up and down to adjust the angle of the cleaning substrate 8; similarly, if it is necessary to reversely adjust the angle of the cleaning substrate 8, the motor reverse command is input to the mobile phone terminal again, so that the cleaning substrate 8 can be tilted to the other side, so as to match the setting angle of the photovoltaic panel 12 in a larger range.

[0037] In the solution of the present invention, side plates 9 are provided at both ends of the cleaning substrate 8 , and the cleaning mechanism is provided between the two side plates 9 .

[0038] The cleaning mechanism includes a brush roller 10 between two side plates 9, and cleaning rollers 11 are symmetrically arranged on both sides of the brush roller 10. The brush roller 10 and the two cleaning rollers 11 are connected by belt transmission. A stepper motor 92 is arranged on the outer side of one of the side plates 9, and the output shaft of the stepper motor 92 passes through the side plate 9 and is connected to the brush roller 10. When the stepper motor 92 is running, the brush roller 10 and the cleaning roller 11 rotate simultaneously. In this embodiment, the bottom heights of the brush roller 10 and the cleaning roller 11 are consistent, and both can contact the surface of the photovoltaic panel 12, thereby cleaning the surface of the photovoltaic panel 12.

[0039] In order to further improve the cleaning effect, a liquid storage tank 4 is also provided above the drone base 1, and a liquid filling port 41 is provided on the surface of the liquid storage tank 4, and a connecting pipe 81 is provided on the surface of the cleaning substrate 8. The liquid storage tank 4 and the connecting pipe 81 are connected through a connecting hose 42. Two rows of nozzles 82 are provided on the bottom surface of the cleaning substrate 8, and the nozzles 82 pass through the cleaning substrate 8 and are connected with the connecting pipe 81. The two rows of nozzles 82 are located directly above the cleaning roller 11.

[0040] The liquid in the liquid storage tank 4 is cleaning liquid, washing liquid, etc., and a micro pump for conveying liquid is also provided in the liquid storage tank 4, and the micro pump is connected to the connecting hose 42; when the UAV is flying, the stepper motor 92 and the micro pump run at the same time, which can ensure that the photovoltaic panel is cleaned with the cleaning liquid, thereby improving the cleaning effect.

[0041] In addition, two detachable traveling gears 93 are provided on the inner sides of the two side panels 9, two motor covers 91 are provided on the outer side of one of the side panels 9, and a built-in motor is provided in the motor cover 91. The two built-in motors are transmission-connected to the two traveling gears 93 on the same side, and reference racks 13 are provided on both sides of the photovoltaic panel 12. The four traveling gears 93 are respectively meshed with the reference racks 13 on both sides. After the built-in motor is running, it drives the whole to move along the reference rack 13.

[0042] In this embodiment, the cleaning mechanism has two operating modes: One method is to use the drone to fly horizontally and remove the traveling gear 93 before use. When the drone flies horizontally, the brush roller 10 and the cleaning roller 11 both contact the surface of the photovoltaic panel 12, thereby cleaning the surface of the photovoltaic panel; the other method is to stop the drone, install the traveling wheel 93, and then start the built-in motor in the motor cover 91. At this time, after the built-in motor runs, the traveling gear 93 cooperates with the reference rack 13, thereby driving the entirety to move along the reference rack 13.

[0043] Regardless of which of the above cleaning methods is used, the stepper motor 92 is in an on-working state; when cleaning is performed in the built-in motor mode, the drone stops running, which can save the power of the drone.

[0044] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
