However, current solar photovoltaic panels are exposed outdoors and often have dust on them that blocks the light, which greatly affects the conversion of light energy. Therefore, it is very important to clean the solar photovoltaic panels.

[0003] In the prior art, the invention patent with application number 202310391072.2 discloses a solar photovoltaic panel cleaning device and a cleaning method thereof, including a bracket, a photovoltaic panel is fixedly connected to the top of the bracket, a cleaning mechanism is fixedly connected to the end of the photovoltaic panel away from the bracket, a water spraying mechanism is fixedly connected to the inner wall of the bracket, and the outer surface of the water spraying mechanism is fixedly connected to a water pump.

The water spraying mechanism includes a water storage tank, and the water pump draws water into the water storage tank for storage. When needed, the water spraying mechanism sprays water onto the outer surface of the photovoltaic panel, and then the cleaning mechanism cleans the outer surface of the photovoltaic panel.

[0028] The present invention also provides a technical solution: A self-cleaning method for an angle-adjustable solar photovoltaic panel self-cleaning device comprises the following steps: The whole device is moved to the side of the solar photovoltaic panel to be cleaned, and the tilt angle of the solar photovoltaic panel to be cleaned is determined by an angle detection instrument; wherein the angle detection instrument is selected from an inclinometer or an inclination sensor.

[0029] According to the obtained tilt angle of the solar photovoltaic panel to be cleaned, the tilt angle of the cleaning assembly 3 is adjusted by the cooperation of the Y-axis height adjustment mechanism, the X-axis position adjustment mechanism and the angle adjustment mechanism 2 to ensure that the cleaning belt 39 is always in close contact with the surface of the solar photovoltaic panel to be cleaned; The cleaning assembly 3 is driven to move along the X-axis direction by the X-axis position adjustment mechanism to clean the surface of the solar photovoltaic panel to be cleaned.

[0030] Embodiment: Move the whole device to the side of the solar photovoltaic panel to be cleaned, and determine the tilt angle of the solar photovoltaic panel to be cleaned by the tilt sensor. The tilt sensor is detachably connected to the back of the solar photovoltaic panel to be cleaned. The tilt sensor usually uses the principle of gravity acceleration to measure the tilt angle of an object. When the object tilts, the sensitive element inside the tilt sensor will be deformed by the gravity, thereby converting the tilt angle into an electrical signal output; According to the obtained inclination angle of the solar photovoltaic panel to be cleaned, the inclination angle of the cleaning component 3 is adjusted by the cooperation of the Y-axis height adjustment mechanism, the X-axis position adjustment mechanism and the angle adjustment mechanism 2, so as to ensure that the cleaning belt 39 is always in close contact with the surface of the solar photovoltaic panel to be cleaned; when adjusting the inclination angle of the cleaning component 3, firstly, the Y-axis driving screw 1102 is driven to rotate by the height adjustment motor 11, thereby driving the adjustment seat 1204 to move up and down along the Y-axis guide rod 1103, when the height adjustment motor 11 drives the Y-axis driving screw 1102 to rotate forward, the adjustment seat 1204 moves upward along the Y-axis guide rod 1103; when the height adjustment motor 11 drives the Y-axis driving screw 1102 to reverse, the adjustment seat 1204 moves downward along the Y-axis guide rod 1103; thereby realizing the change of the Y-axis height of the cleaning component 3. Then, the X-axis telescopic cylinder 1203 drives the X-axis driving rod 1202 to extend or retract, thereby driving the connecting member 12 to move left and right along the X-axis direction, thereby driving the connecting block 21 fixedly connected to the connecting member 12 to move left and right along the X-axis direction, thereby driving the angle adjustment mechanism 2 to move left and right along the X-axis direction.

[0031] When the angle adjustment mechanism 2 and the cleaning component 3 are moved to the top of the solar photovoltaic panel to be cleaned by the Y-axis height adjustment mechanism and the X-axis position adjustment mechanism, the inclination angle of the linear module 27 connected to the inclined plate 26 is adjusted by adjusting the length of the length adjustment rod 25. The length adjustment rod 25 includes an adjustment section in the middle and hinged sections at both ends of the adjustment section. An adjustment nut and two adjustment rods threaded with the adjustment nut are arranged at the center of the adjustment section. The threads on the surfaces of the two adjustment rods are forward and reverse threads. When the adjustment nut rotates forward, the two adjustment rods move toward the direction of the adjustment nut at the same time under the action of the thread, thereby shortening the length of the entire length adjustment rod 25; when the adjustment nut rotates reversely, the two adjustment rods move away from the adjustment nut at the same time under the action of the thread, thereby extending the length of the entire length adjustment rod 25; when the length of the length adjustment rod 25 becomes shorter, the inclination angle of the inclined plate 26 becomes smaller and tends to be horizontal; when the length of the length adjustment rod 25 becomes longer, the inclination angle of the inclined plate 26 becomes larger and tends to be vertical, and finally the inclination angle of the linear module 27 is adjusted, thereby adjusting the inclination angle of the cleaning component 3. Ensure that the cleaning belt 39 always closely fits the surface of the solar photovoltaic panel to be cleaned.

[0032] After the adjustment is completed, the cleaning assembly 3 is driven to move along the X-axis guide rod 1201 in the X-axis direction through the X-axis position adjustment mechanism in cooperation with the X-axis telescopic cylinder 1203 and the X-axis driving rod 1202 to clean the surface of the solar photovoltaic panel to be cleaned.

[0033] During cleaning, the blower mechanism 32 is arranged at the front end in the direction of travel, and the blower cooperates with the blowing duct 3201 and the plurality of blowing ports 3202 to preliminarily clean the debris and dust on the surface of the solar photovoltaic panel.

[0034] Then, the cleaning belt 39 near the side of the blower mechanism 32 is driven by the servo motor 41 in cooperation with the driving wheel 36 and the driven wheel 37 to rotate forward or reverse. Figure 5 As shown, the cleaning belt 39 near the side of the blower mechanism 32 is driven by the servo motor 41 in cooperation with the driving wheel 36 and the driven wheel 37 to rotate right or left, and finally the cleaning belt 39 cooperates with the nozzle 42 to clean the surface of the solar photovoltaic panel; the cleaning belt 39 near the side of the drying mechanism 40 is driven by the servo motor 41 in cooperation with the driving wheel 36 and the driven wheel 37 to reverse, that is, Figure 5 As shown, the cleaning belt 39 near the drying mechanism 40 rotates to the left under the drive of the servo motor 41 in cooperation with the driving wheel 36 and the driven wheel 37, ensuring that the cleaning belt 39 can pass through the nozzle 42, the extrusion mechanism 38 and the drying mechanism 40 in sequence, thereby ensuring that the surface of the cleaning belt 39 in contact with the surface of the solar photovoltaic panel always remains dry. During the rotation of the cleaning belt 39 near the blower mechanism 32, the nozzle 42 close to it sprays water at the position where it contacts the solar photovoltaic panel, and the surface of the solar photovoltaic panel is cleaned by the cleaning belt 39. As the entire cleaning assembly 3 moves, the cleaning belt 39 on the other side cleans the water stains remaining on the surface of the solar photovoltaic panel. The cleaning belt 39 on the side of the box body away from the blower mechanism 32 cooperates with the drying mechanism 40, the squeezing mechanism 38 and the nozzle 42. When in use, it can ensure that the cleaning belt 39 is always in a dry state. When in use, firstly, the cleaning belt 39 contacting the surface of the solar photovoltaic panel is flushed with water through the nozzle 42, and then the cleaning belt 39 is squeezed by the squeezing mechanism 38 to remove excess water adsorbed by it, and finally it is dried by the drying mechanism 40 to ensure that after the cleaning belt 39 on the other side cleans the surface of the solar photovoltaic panel with water, the cleaning belt 39 on the side with the drying mechanism 40 can adsorb excess water stains on the surface of the solar photovoltaic panel.

[0035] During the cleaning process, the cleaning belt 39 passes through the squeezing mechanism 38, which includes a collection chamber 3803 connected to the bottom of the mounting frame 34, and a positioning wheel 3801 and a squeezing wheel 3802 are respectively arranged inside the collection chamber 3803, and the surface of the positioning wheel 3801 is provided with an arc-shaped groove that is concave inward, and the surface of the squeezing wheel 3802 is provided with an arc-shaped convex block that is convex outward, and the convex block and the groove are connected with each other, and the cleaning belt 39 is arranged between the convex block and the groove. The gap between the positioning wheel 3801 and the squeezing wheel 3802 is smaller than the thickness of the cleaning belt 39, so as to ensure that the positioning wheel 3801 and the squeezing wheel 3802 can fully squeeze the cleaning belt 39 and discharge the adsorbed sewage into the collection chamber 3803.

[0036] The two cleaning belts 39 are connected to the slide 43 inside the box body through the driving wheel 36 and the driven wheel 37 in cooperation with the slider. The ends of the slide 43 are provided with a return spring, and the other end of the return spring is connected to the slider. Through the action of the slide 43, the slider and the return spring, in cooperation with the lifting cylinder 33 and the mounting frame 34, when the lifting cylinder 33 is retracted, the driving wheel 36 and the driven wheel 37 are moved toward the center along the slide 43 through the slider. When the lifting cylinder 33 is extended, the driving wheel 36 and the driven wheel 37 move to both sides along the slide 43 through the action of the slider and the return spring, so that the length of the entire cleaning belt 39 contacting the solar photovoltaic panel can be adjusted, and it can be used to clean solar photovoltaic panels of different sizes.

[0037] The mounting seat 29 is slidably connected to the working surface of the linear module 27. The driving motor 28 on one side of the linear module 27 cooperates with the transmission parts to drive the transmission screw inside the linear module 27, thereby driving the mounting seat 29 to move along the length direction of the linear module 27. When in use, the position of the cleaning component 3 along the length direction of the linear module 27 can be fine-tuned.
