Description
Technical Field
[0001] This invention relates to the field of photovoltaic panel technology, specifically to a photovoltaic panel with self-cleaning function and its cleaning method. Background Technology
[0002] Solar energy refers to the thermal radiation energy of the sun. Therefore, solar energy is a clean energy source. In real life, photovoltaic power generation technology is often used to convert solar energy into electrical energy for utilization and storage. The core component of photovoltaic power generation technology is the photovoltaic panel. When using photovoltaic panels, they need to be aligned with the sun. Therefore, in order to prevent buildings or trees from blocking the photovoltaic panels, they are often installed in a high position.
[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: When using photovoltaic panels in winter, the surface of the photovoltaic panels is easily covered by snow. When the ambient temperature is low, the snow melts slowly during the day and the resulting snow water is easily frozen into ice at night, causing the snow to harden and making it difficult to clear. Furthermore, since the photovoltaic panels are installed at a high position, it is difficult to clear the snow in time, which can easily cause the photovoltaic panels to malfunction and greatly reduce the power generation efficiency of the photovoltaic panels.
[0004] Therefore, we propose a photovoltaic panel with self-cleaning function and its cleaning method. Summary of the Invention
[0005] The purpose of this invention is to provide a photovoltaic panel with self-cleaning function and a cleaning method thereof, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic panel with self-cleaning function and a cleaning method thereof, comprising a column, a bracket fixedly connected to the upper end of the column, a photovoltaic panel body fixedly connected to the surface of the bracket, and further comprising: a cleaning structure disposed on the surface of the bracket for automatically cleaning ice and snow adhering to the surface of the photovoltaic panel body, the cleaning structure comprising a guide rail fixedly installed on the surface of the bracket, a dividing wire and a rigid tube for scraping ice and snow, and an auxiliary gear for driving the dividing wire to rotate; an auxiliary structure disposed on the surface of the bracket for improving the cleaning effect on the photovoltaic panel body, the auxiliary structure comprising an L-shaped plate fixedly installed on the surface of the bracket, a scraper for scraping the photovoltaic panel body, and a partition for adjusting the distance between the scraper and the photovoltaic panel body; and a shielding structure disposed on the surface of the bracket for preventing snow from hindering the normal operation of the cleaning structure, the shielding structure comprising a shielding frame fixedly installed on the surface of the bracket and a through hole for ensuring that the scraper can slide normally.
[0007] The aforementioned components achieve the following effects: By setting up a cleaning structure, the system can automatically remove ice and snow adhering to the surface of the photovoltaic panel, ensuring the panel can function normally and guaranteeing that its power generation efficiency is not affected by snow accumulation. Furthermore, it can break up the ice and snow into smaller pieces, preventing large chunks from falling and hitting people or objects below. By setting up an auxiliary structure, a scraper can remove any remaining melted snow water from the surface of the photovoltaic panel, preventing it from refreezing and further improving the cleaning effect. By setting up a shielding structure, a shielding frame can cover some parts of the cleaning structure, preventing melted and frozen snow from affecting its normal operation, thus reducing maintenance requirements and making the cleaning structure more practical.
[0008] Preferably, there are two guide rails. A sliding frame is slidably connected to the surface of each guide rail. A servo motor is fixedly connected to the surface of the sliding frame. Synchronizing rods are fixedly connected to the output ends of the two servo motors. Two main gears are fixedly connected to the arc surface of the synchronizing rods. The main gears mesh with auxiliary gears. A rack is fixedly connected to the support relative to the position of the main gears. The rack meshes with the main gears. A rotating shaft is rotatably connected inside the sliding frame. One end of the rotating shaft is fixedly connected to an auxiliary gear. Both ends of the dividing wire are fixedly connected to the two auxiliary gears respectively. A heating element is fixedly connected between the two auxiliary gears. A rigid tube is fixedly installed on the arc surface of the heating element. Brush bristles are fixedly connected to the rigid tube relative to the position of the heating element, and the brush bristles penetrate the rigid tube. The diameter of the main gear is larger than the diameter of the auxiliary gear.
[0009] The aforementioned components achieve the following effects: Starting the servo motor and energizing the heating element causes the synchronizing rod to rotate via the output of the servo motor, which in turn drives the main gear. Since the main gear meshes with the rack, it drives the servo motor to move. This movement of the servo motor causes the sliding frame to slide along the surface of the guide rail, which restricts the sliding path of the frame. The sliding frame's movement drives the rotating shaft, which in turn drives the auxiliary gear. Since the auxiliary gear meshes with the main gear, the rotation of the main gear drives the auxiliary gear to rotate. The auxiliary gear then drives the dividing wire to simultaneously tilt upwards and rotate around the axis of the rotating shaft. The heating element, aided by the rotation of the auxiliary gear, drives the rigid tube to rotate. The rigid tube first contacts the snow on the surface of the photovoltaic panel and creates grooves on the snow surface. Then, the dividing wire contacts the snow, dividing it into smaller pieces. Because the snow surface already has grooves, the snow is broken into multiple fragments, preventing large chunks of snow from falling from a height and hitting people or objects below.
[0010] Preferably, a heat-conducting wire is fixedly connected to the arc surface of the heating element, and the other end of the heat-conducting wire is fixedly connected to a dividing wire. The heat-conducting wire is made of copper alloy.
[0011] The effect achieved by the above components is that the heat-conducting wire transfers the heat from the heating element to the dividing wire, so that when the dividing wire comes into contact with the snow, it can melt the snow, making it easier to clean up the snow.
[0012] Preferably, the arc surface of the rigid tube has a groove, the size of which is adapted to the size of the bristles.
[0013] The aforementioned components achieve the following effect: the groove facilitates the bending of the bristles after they come into contact with the snow, and prevents the bristles from being broken by the snow and the hard tube as they slide along the snow surface.
[0014] Preferably, a strip frame is fixedly connected to the surface of the short arm of the L-shaped plate, the partition is fixedly installed on the inner wall of the strip frame, a guide plate is rotatably connected to the surface of the partition, a connecting plate is slidably connected to the inner wall of the strip frame, the connecting plate is slidably connected to the partition, the scraper is fixedly installed on the lower surface of the connecting plate, a round rod slides through the connecting plate, the round rod is fixedly connected to the sliding frame, the scraper is made of rubber, and the cross-section of the scraper is "V" shaped.
[0015] The aforementioned components achieve the following effects: the sliding of the round rod will cause the connecting plate to slide. As the connecting plate slides along the inner wall of the strip frame, the scraper will slide along the surface of the photovoltaic panel body. At this time, the rubber scraper can clean the melted snow water remaining on the surface of the photovoltaic panel body, thereby preventing the snow water from freezing again. In addition, the scraper can also clean dust and other foreign objects. Since the cross-section of the scraper is "V" shaped, dust and other foreign objects will slide along the middle of the photovoltaic panel body to both sides after contacting the scraper, thus making it easy to clean the dust and other foreign objects.
[0016] Preferably, a plurality of leaf springs are fixedly connected to the outer wall of the strip frame, and a pressure plate is fixedly connected to one end of each leaf spring. One end of the pressure plate has an arc-shaped structure. Both ends of the connecting plate are provided with relief grooves. A trapezoidal block is slidably connected to the inner wall of the relief groove. Two springs are fixedly connected to the surface of the trapezoidal block, and the other end of the springs is fixedly installed on the inner wall of the relief groove.
[0017] The above components achieve the following effects: the sliding of the connecting plate will cause the trapezoidal block to slide, and the flat surface of the trapezoidal block will contact the arc segment of the pressure plate. At this time, the trapezoidal block will squeeze the pressure plate, causing the pressure plate to slide upward. Since it is the flat surface of the trapezoidal block that contacts the pressure plate, the trapezoidal block will not slide into the relief groove again. The sliding of the pressure plate will also squeeze the leaf spring. At this time, the leaf spring is in a compressed state. Therefore, the pressure plate will squeeze the trapezoidal block with the help of the elastic force of the leaf spring. The trapezoidal block will press the connecting plate against the inner wall of the strip frame, and the connecting plate will press the scraper tightly against the surface of the photovoltaic panel body.
[0018] Preferably, a limiting plate is fixedly connected to the surface of the pressure plate, and the limiting plate is slidably connected to the strip frame.
[0019] The effect achieved by the above components is that the sliding of the pressure plate will cause the limiting plate to slide along the surface of the strip frame, and the limiting plate will restrict the sliding path of the pressure plate.
[0020] Preferably, the through hole is formed on the side wall of the shielding frame, and the dividing wire, heating tube, connecting plate and scraper all pass through the through hole. A bending plate is fixedly connected to the surface of the shielding frame, and a baffle is slidably connected to the inner wall of the bending plate. The baffle is slidably connected to the shielding frame, and the size of the baffle is adapted to the size of the through hole.
[0021] The aforementioned components achieve the following effects: after the connecting plate contacts the baffle, it will compress the baffle, and the baffle will slide along the surface of the bent plate and the strip frame. The bent plate restricts the sliding path of the baffle. When the sliding frame slides downward along the surface of the slide rail, the baffle will slide synchronously to block the through hole. Therefore, the baffle and the blocking frame can block the main gear, auxiliary gear and rack, etc., to prevent snow from melting and freezing on the tooth surface of the main gear, auxiliary gear or rack, thus affecting the normal operation of the cleaning structure.
[0022] Preferably, a traction rope is fixedly connected to the surface of the baffle, the other end of the traction rope is fixedly connected to the shielding frame, a counterweight is fixedly connected to the arc surface of the traction rope, a rotating block is rotatably connected to the outer wall of the shielding frame, and the traction rope passes through the rotating block.
[0023] The effect achieved by the above components is as follows: when the counterweight moves downward with the help of its own weight, the help rope will cause the baffle to slide in the opposite direction. The counterweight and the help rope work together to ensure that the baffle can automatically reset.
[0024] Preferably, a cleaning method for a photovoltaic panel with self-cleaning function includes the following steps: S1. When it snows, the main gear, auxiliary gear and rack are shielded by the shielding frame and baffle to prevent snow from melting and freezing on the tooth surface of the main gear, auxiliary gear or rack and affecting the normal operation of the cleaning structure. S2. When clearing snow, the servo motor is started and power is supplied to the heating element. At this time, the rigid tube will create grooves on the surface of the snow, and the dividing wires can separate the snow into pieces, allowing the snow to slide off the surface of the photovoltaic panel, thus achieving snow clearing. S3. Control the output end of the servo motor to reverse, so that the scraper sticks against the surface of the photovoltaic panel body and slides along the surface of the photovoltaic panel body. The scraper stick removes the snow water remaining on the surface of the photovoltaic panel body, thereby achieving further cleaning of the photovoltaic panel body.
[0025] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up a cleaning structure, can automatically clean the ice and snow attached to the surface of the photovoltaic panel, so that the photovoltaic panel can work normally and ensure that the power generation efficiency of the photovoltaic panel is not affected by the snow. It can also break the ice and snow into small pieces to prevent large pieces of snow from falling and hitting people or objects below.
[0026] By setting up an auxiliary structure, this invention can use a scraper to clean the residual melted snow water on the surface of the photovoltaic panel, thereby preventing the snow water from freezing again and further improving the cleaning effect on the photovoltaic panel.
[0027] This invention uses a shielding structure to cover some parts of the cleaning structure with a shielding frame, preventing snow from affecting the normal operation of the cleaning structure after it melts and freezes, thereby reducing the maintenance requirements of the cleaning structure and making it more practical.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] Please see Figure 1-11 This invention provides a technical solution: a photovoltaic panel with self-cleaning function and its cleaning method, including a column 1, a support 2 fixedly connected to the upper end of the column 1, a photovoltaic panel body 3 fixedly connected to the surface of the support 2, and further including: a cleaning structure 4 disposed on the surface of the support 2 for automatically cleaning ice and snow adhering to the surface of the photovoltaic panel body 3, the cleaning structure 4 including a guide rail 401 fixedly installed on the surface of the support 2, a dividing wire 410 and a rigid tube 412 for scraping ice and snow, and an auxiliary gear 408 for driving the dividing wire 410 to rotate. The auxiliary structure 5, which is set on the surface of the bracket 2 to improve the cleaning effect on the photovoltaic panel body 3, includes an L-shaped plate 501 fixedly installed on the surface of the bracket 2, a scraper 507 for scraping the photovoltaic panel body 3, and a partition 503 for adjusting the distance between the scraper 507 and the photovoltaic panel body 3; and a shielding structure 6, which is set on the surface of the bracket 2 to prevent snow accumulation from hindering the normal operation of the cleaning structure 4, includes a shielding frame 61 fixedly installed on the surface of the bracket 2 and a through hole 66 for ensuring that the scraper 507 can slide normally.
[0032] The following section will explain the specific settings and functions of its cleaning structure 4, auxiliary structure 5, and shielding structure 6.
[0033] like Figure 2-5As shown, there are two guide rails 401. A sliding frame 402 is slidably connected to the surface of the guide rail 401. A servo motor 403 is fixedly connected to the surface of the sliding frame 402. Synchronizing rods 404 are fixedly connected to the output ends of the two servo motors 403. Two main gears 405 are fixedly connected to the arc surface of the synchronizing rod 404. The main gears 405 mesh with auxiliary gears 408. A rack 406 is fixedly connected to the bracket 2 relative to the position of the main gears 405. The rack 406 meshes with the main gears 405. A rotating shaft 407 is rotatably connected inside the sliding frame 402. One end of the 7 is fixedly connected to the auxiliary gear 408. Both ends of the dividing wire 410 are fixedly connected to the two auxiliary gears 408 respectively. A heating element 409 is fixedly connected between the two auxiliary gears 408. A rigid tube 412 is fixedly installed on the arc surface of the heating element 409. Brush bristles 413 are fixedly connected to the rigid tube 412 relative to the heating element 409, penetrating the rigid tube 412. The diameter of the main gear 405 is larger than the diameter of the auxiliary gear 408. The servo motor 403 is started, and the heating element 409 is energized. The synchronizing rod 404, aided by the output of the servo motor 403... The rotation of the end gear drives the main gear 405 to rotate. Since the main gear 405 meshes with the rack 406, the main gear 405 drives the servo motor 403 to move. The movement of the servo motor 403 drives the sliding frame 402 to slide along the surface of the guide rail 401. The guide rail 401 restricts the sliding path of the sliding frame 402. The sliding of the sliding frame 402 drives the rotating shaft 407 to move. The movement of the rotating shaft 407 drives the auxiliary gear 408 to move. Since the auxiliary gear 408 meshes with the main gear 405, the rotation of the main gear 405 drives the auxiliary gear 408 to rotate. Gear 408 drives the dividing wire 410 to simultaneously tilt upwards and rotate around the axis of shaft 407. The heating element 409, aided by the rotation of the auxiliary gear 408, drives the rigid tube 412 to rotate. The rigid tube 412 first contacts the snow on the surface of the photovoltaic panel 3 and grooves the snow. Then, the dividing wire 410 contacts the snow, dividing it into smaller pieces. Because the snow surface already has grooves, the snow is broken into multiple fragments, preventing large chunks of snow from falling and hitting people or objects below. A heat-conducting wire 411 is fixedly connected to the arc surface of the heating element 409. The other end of the heat-conducting wire 411 is fixedly connected to the dividing wire 410. The heat-conducting wire 411 is made of copper alloy and transfers heat from the heating element 409 to the dividing wire 410, allowing the dividing wire 410 to melt the snow upon contact, thus facilitating snow removal. The arc surface of the rigid tube 412 is provided with a groove 414. The size of the groove 414 is adapted to the size of the bristles 413. The groove 414 facilitates the bending of the bristles 413 after contact with the snow, and prevents the bristles 413 from being pinched and broken by the snow and the rigid tube 412 during the process of the rigid tube 412 sliding along the snow surface.
[0034] like Figure 2 and Figure 5-9 As shown, a strip frame 502 is fixedly connected to the surface of the short arm of the L-shaped plate 501. A partition plate 503 is fixedly installed on the inner wall of the strip frame 502. A guide plate 504 is rotatably connected to the surface of the partition plate 503. A connecting plate 505 is slidably connected to the inner wall of the strip frame 502. The connecting plate 505 is slidably connected to the partition plate 503. A scraper 507 is fixedly installed on the lower surface of the connecting plate 505. A round rod 506 slides through the connecting plate 505. The round rod 506 is fixedly connected to the sliding frame 402. The scraper 507 is made of rubber and has a "V" shaped cross-section. The round rod 506 slides and... As the connecting plate 505 slides along the inner wall of the strip frame 502, the scraper 507 slides along the surface of the photovoltaic panel body 3. At this time, the rubber scraper 507 can clean the melted snow water remaining on the surface of the photovoltaic panel body 3, thereby preventing the snow water from freezing again. In addition, the scraper 507 can also clean dust and other foreign objects. Since the cross-section of the scraper 507 is "V" shaped, dust and other foreign objects will slide along the middle of the photovoltaic panel body 3 to both sides after contacting the scraper 507, thus making it easy to clean the dust and other foreign objects. Several leaf springs 508 are fixedly connected to the outer wall of the strip frame 502. A pressure plate 509 is fixedly connected to one end of each leaf spring 508. One end of the pressure plate 509 has an arc-shaped structure. Both ends of the connecting plate 505 have clearance grooves 511. A trapezoidal block 513 is slidably connected to the inner wall of the clearance groove 511. Two springs 512 are fixedly connected to the surface of the trapezoidal block 513. The other ends of the springs 512 are fixedly installed on the inner wall of the clearance groove 511. When the connecting plate 505 slides, it causes the trapezoidal block 513 to slide. The plane of the trapezoidal block 513 contacts the arc segment of the pressure plate 509. At this time, the trapezoidal block 513 presses against the pressure plate 509, causing the pressure plate 509 to slide upwards. Furthermore, because the plane of the trapezoidal block 513 is in contact with the arc segment of the pressure plate 509... When the pressure plate 509 contacts, the trapezoidal block 513 will not slide back into the clearance groove 511. The sliding of the pressure plate 509 will also compress the leaf spring 508. At this time, the leaf spring 508 is in a compressed state. Therefore, the pressure plate 509 will use the elastic force of the leaf spring 508 to compress the trapezoidal block 513. The trapezoidal block 513 will press the connecting plate 505 against the inner wall of the strip frame 502. The connecting plate 505 will press the scraper 507 tightly against the surface of the photovoltaic panel body 3. The surface of the pressure plate 509 is fixedly connected to the limiting plate 510. The limiting plate 510 is slidably connected to the strip frame 502. The sliding of the pressure plate 509 will drive the limiting plate 510 to slide along the surface of the strip frame 502. The limiting plate 510 achieves the function of restricting the sliding path of the pressure plate 509.
[0035] like Figure 2 and Figure 10 as well as Figure 11As shown, a through hole 66 is formed on the side wall of the shielding frame 61. The dividing wire 410, the heating element 409, the connecting plate 505, and the scraper 507 all pass through the through hole 66. A bent plate 62 is fixedly connected to the surface of the shielding frame 61. A baffle 63 is slidably connected to the inner wall of the bent plate 62. The baffle 63 is slidably connected to the shielding frame 61. The size of the baffle 63 is adapted to the size of the through hole 66. When the connecting plate 505 contacts the baffle 63, it will squeeze the baffle 63. The baffle 63 will move along the bent plate 62 and the strip frame 507. The surface of 02 slides, and the bending plate 62 restricts the sliding path of the baffle 63. When the sliding frame 402 slides downward along the surface of the slide rail, the baffle 63 will slide synchronously to block the through hole 66. Therefore, the baffle 63 and the blocking frame 61 can block the main gear 405, auxiliary gear 408 and rack 406 and other components, preventing snow from melting and freezing on the tooth surface of the main gear 405, auxiliary gear 408 or rack 406 and affecting the normal operation of the cleaning structure 4. A traction rope 64 is fixedly connected to the surface of the baffle 63. The other end of the traction rope 64 is fixedly connected to the shielding frame 61. A counterweight 65 is fixedly connected to the arc surface of the traction rope 64. A rotating block 67 is rotatably connected to the outer wall of the shielding frame 61. The traction rope 64 passes through the rotating block 67. When the counterweight 65 moves the traction rope 64 downward by its own weight, the traction rope 64 will cause the baffle 63 to slide in the opposite direction. The counterweight 65 and the traction rope 64 work together to ensure that the baffle 63 can automatically reset.
[0036] like Figure 9 and Figure 10 As shown, a cleaning method for a photovoltaic panel with self-cleaning function includes the following steps: S1. When it snows, the shielding frame 61 and the baffle 63 are used to shield the main gear 405, auxiliary gear 408 and rack 406 to prevent snow from melting and freezing on the tooth surfaces of the main gear 405, auxiliary gear 408 or rack 406 and affecting the normal operation of the cleaning structure 4. S2. When clearing snow, the servo motor 403 is started and power is supplied to the heating element 409. At this time, the rigid tube 412 will create grooves on the surface of the snow, and the dividing wire 410 can separate the snow into pieces, allowing the snow to slide off the surface of the photovoltaic panel, thus achieving the clearing of the snow. S3. Control the output end of the servo motor 403 to reverse, so that the scraper 507 presses against the surface of the photovoltaic panel body 3 and slides along the surface of the photovoltaic panel body 3. The scraper 507 removes the snow water remaining on the surface of the photovoltaic panel body 3, thereby achieving further cleaning of the photovoltaic panel body 3.
[0037] Working principle: Both the auxiliary gear 408 and the main gear 405 are standard parts, and they are used in conjunction with each other. When it is necessary to clean the ice and snow adhering to the surface of the photovoltaic panel body 3, the servo motor 403 is started and the heating element 409 is energized. The synchronous rod 404 rotates through the output end of the servo motor 403, which drives the main gear 405 to rotate. Since the main gear 405 meshes with the rack 406, it drives the servo motor 403 to move. The movement of the servo motor 403 drives the sliding frame 402 to move along the surface of the guide rail 401. The guide rail 401 restricts the sliding path of the sliding frame 402. The sliding of the sliding frame 402 drives the rotating shaft 407 to move, which in turn drives the auxiliary gear 408 to move. Since the auxiliary gear 408 meshes with the main gear 405, the rotation of the main gear 405 drives the auxiliary gear 408 to rotate. The auxiliary gear 408 drives the dividing wire 410 to move upwards and rotate around the axis of the rotating shaft 407. The heating element 409, with the help of the rotation of the auxiliary gear 408, drives the rigid tube 412 to rotate. The rigid tube 412 first contacts the snow accumulation on the surface of the photovoltaic panel body 3. The brush touches and creates grooves on the surface of the snow. During this process, the grooves 414 facilitate the bending of the bristles 413 after contact with the snow, preventing the bristles 413 from being broken by the snow and the rigid tube 412 as it slides along the snow surface. Then, the dividing wires 410 come into contact with the snow and divide it. Because the snow surface already has grooves, the snow is now divided into multiple pieces, preventing large chunks of snow from falling from a height and hitting people or objects below. Furthermore, the dividing wires 410, after contacting the snow, will move away from the snow... The rotation away from the photovoltaic panel body 3 prevents the dividing wire 410 from carrying snow closer to the photovoltaic panel body 3, thus preventing the snow from squeezing and damaging the photovoltaic panel body 3. During this process, the heating tube 409 is heated, and the heat-conducting wire 411 transfers the heat from the heating tube 409 to the dividing wire 410, so that the dividing wire 410 can melt the snow when it comes into contact with the snow, making it easier to clean the snow. At the same time, the heating tube 409 heats the surrounding air, thereby using the hot air to melt the snow remaining on the surface of the cleaned photovoltaic panel body 3.
[0038] As the sliding frame 402 slides upwards along the surface of the guide rail 401, the round rod 506, aided by the sliding frame 402, drives the connecting plate 505 to slide. The connecting plate 505 first slides along the surface of the guide plate 504. During this process, the distance between the connecting plate 505 and the photovoltaic panel body 3 increases, and the scraper 507 also moves with the connecting plate 505 and disengages from the photovoltaic panel body 3. This prevents the connecting plate 505 and the scraper 507 from contacting the snow and obstructing the normal sliding of the sliding frame 402. The round rod 506 effectively limits the sliding path of the connecting plate 505, ensuring that the connecting plate 505 remains parallel to the photovoltaic panel body 3. Afterwards, the connecting plate 505 slides onto the surface of the partition plate 503. 05 will cause the trapezoidal block 513 to slide, and the inclined surface of the trapezoidal block 513 will contact the strip frame 502. The trapezoidal block 513 will be squeezed by the strip frame 502 and slide into the relief groove 511, thereby avoiding the trapezoidal block 513 from hindering the normal sliding of the connecting plate 505. As the sliding frame 402 slides, the connecting plate 505 will disengage from the partition plate 503. Under the influence of its own gravity, the connecting plate 505 will slide along the arc surface of the round rod 506 towards the photovoltaic panel body 3. At this time, the trapezoidal block 513 will slide out of the relief groove 511 and pass through the strip frame 502 with the help of the tension of the spring 512. Then, the output end of the servo motor 403 will reverse, and the heating tube 409 will drive the bristles 413 to rotate in the opposite direction. At this time, the bristles 413 will brush and polish. Snow residue remains on the surface of the bristles 413, while the rigid tube 412 supports the bristles 413, thus improving the cleaning effect of the bristles 413. The sliding of the round rod 506 causes the connecting plate 505 to slide, which in turn causes the trapezoidal block 513 to slide. The flat surface of the trapezoidal block 513 contacts the arc segment of the pressure plate 509. At this time, the trapezoidal block 513 will press the pressure plate 509, causing the pressure plate 509 to slide upward. Since it is the flat surface of the trapezoidal block 513 that contacts the pressure plate 509, the trapezoidal block 513 will not slide back into the relief groove 511. The sliding of the pressure plate 509 will cause the limiting plate 510 to slide along the surface of the strip frame 502. The limiting plate 510 achieves the function of restricting the sliding path of the pressure plate 509. The pressure plate 509 will also compress the spring 508. At this time, the spring 508 is in a compressed state, so the pressure plate 509 will use the elasticity of the spring 508 to press the trapezoidal block 513. The trapezoidal block 513 will press the connecting plate 505 against the inner wall of the strip frame 502. The connecting plate 505 will press the scraper 507 firmly against the surface of the photovoltaic panel body 3. As the connecting plate 505 slides along the inner wall of the strip frame 502, the scraper 507 will slide along the surface of the photovoltaic panel body 3. At this time, the rubber scraper 507 can clean the melted snow water remaining on the surface of the photovoltaic panel body 3, thus preventing the snow water from freezing again. In addition, the scraper 507 can also clean dust and other foreign objects. Because the cross-section of the scraper 507 is "V" shaped...Therefore, dust and other foreign objects will slide along the middle of the photovoltaic panel body 3 to both sides after coming into contact with the scraper 507, thus facilitating the removal of dust and other foreign objects.
[0039] During snow removal, the connecting plate 505 contacts and presses against the baffle 63, causing the baffle 63 to slide along the surfaces of the bent plate 62 and the strip frame 502. The bent plate 62 restricts the sliding path of the baffle 63. The sliding of the baffle 63 pulls the traction rope 64, which slides through the rotating block 67. The rotating block 67 prevents the traction rope 64 from contacting the bent plate 62 and being worn by it. When the sliding frame 402 slides downwards along the surface of the slide rail, the counterweight 65 uses its own weight to move the traction rope 64 downwards. The movement of the traction rope 64 causes the baffle 63 to slide in the opposite direction, aligning the baffle 63 with the through hole. The baffle 63, in conjunction with the baffle frame 61, can shield components such as the main gear 405, auxiliary gear 408, and rack 406, preventing snow from melting and freezing on the tooth surfaces of the main gear 405, auxiliary gear 408, or rack 406, thus affecting the normal operation of the cleaning structure 4. When the traction rope 64 breaks, since both ends of the traction rope 64 are fixedly connected to the baffle frame 61 and the baffle 63 respectively, the counterweight 65 will not fall directly, thus preventing the counterweight 65 from falling from a height and hitting people or objects below. Therefore, the traction rope 64 can both transmit the weight of the counterweight 65 and prevent the counterweight 65 from falling after the traction rope 64 breaks.
