Description

Technical Field

[0001] The invention relates to the technical field of robots, and in particular to a photovoltaic panel cleaning robot. Background Art

[0002] Photovoltaic panel cleaning robots are automated equipment specifically designed to clean solar photovoltaic panels. This type of robot uses advanced technology to efficiently and quickly remove dust, dirt and other debris from the surface of photovoltaic panels, thereby ensuring the optimal operating efficiency of photovoltaic power generation systems. With the rapid development of photovoltaic power generation technology, the application range of photovoltaic panels is becoming wider and wider. During the use of photovoltaic panels, they are often affected by environmental factors such as sand, bird droppings and rainwater. These pollutants not only reduce the photoelectric conversion efficiency of the photovoltaic system, but may also cause damage to the equipment. The design of photovoltaic panel cleaning robots usually combines multiple technologies such as mechanical engineering, automatic control and computer vision to avoid damage to photovoltaic panels and the surrounding environment. In addition, these robots usually have the characteristics of high efficiency, water saving, low noise and environmental protection, making them more sustainable in the cleaning process. With the continuous advancement of technology, future cleaning robots will be more intelligent and provide strong support for the development of the photovoltaic industry.

[0003] Some existing photovoltaic panel cleaning robots are installed on one side of the photovoltaic panel when in use, so as to ensure that the photovoltaic panel can be cleaned in time. However, the cleaning rollers of such robots are mostly in an exposed state, which causes excessive impurities to adhere to the surface of the cleaning rollers after a certain period of time, so that the photovoltaic panel is easily damaged when cleaning. In addition, some cleaning rollers do not have a self-cleaning function when in use, which requires workers to perform regular maintenance on them after use. Therefore, this problem needs to be solved. Summary of the invention

[0040] Working principle: When the photovoltaic panel 101 needs to be cleaned, the third motor 212 will start accordingly, and the second synchronous belt 211 is installed on the output shaft of the third motor 212, and the other end of the second synchronous belt 211 is matched with the worm 206, so that when the third motor 212 is started, the worm 206 will rotate accordingly, and the first worm wheel 205 and the second worm wheel 603 are respectively matched on the surface of the worm 206, so that when the worm 206 rotates, the first worm wheel 205 and the second worm wheel 603 will both rotate, and the first screw rod 204 is installed on the top of the first worm wheel 205, and the cross bar 203 is installed on the surface of the first screw rod 204, and the two ends of the cross bar 203 are installed with connecting plates 202, and the connecting plates 202 slide on Inside the inner shell 2, under the constraint of the connecting plate 202, when the first screw rod 204 rotates, the cross bar 203 can be driven to move downward, and a cleaning roller 201 is installed at the bottom of the cross bar 203, so that when the cross bar 203 drives the cleaning roller 201 to move downward, it can be made to contact the photovoltaic panel 101, and a second screw rod 602 is installed at the bottom of the second worm gear 603, and an adjustment plate 6 is installed on the surface of the second screw rod 602, so that when the second screw rod 602 rotates, the adjustment plate 6 can be moved downward, and a bottom plate 4 is installed at the bottom of the outer shell 1, and the bottom plate 4 is matched with the adjustment plate 6 through the pressure plate 406, so that when the adjustment plate 6 moves downward, the bottom plate 4 will also move downward synchronously, thereby removing the shielding of the cleaning roller 201. When the cleaning roller 201 and the bottom plate 4 move down to the right position, the second motor 108 and the first motor 3 will be started. The output shaft of the second motor 108 is equipped with a first synchronous belt 109, and the other end of the first synchronous belt 109 cooperates with the rotating shaft 105. Therefore, when the second motor 108 is started, the rotating shaft 105 will rotate. Main wheels 104 are installed at both ends of the rotating shaft 105, and the main wheels 104 cooperate with the photovoltaic panel 101. Therefore, when the rotating shaft 105 drives the main wheels 104 to rotate, the cleaning roller 201 can be moved. When the cleaning roller 201 moves, the adjusting plate 6 will also move synchronously. A first rack 604 is installed at the bottom of the adjusting plate 6, and the first rack 604 is in contact with the first rack 604 at the top of the pressing plate 406. The gear 404 cooperates with the first rack 604, so that when the first rack 604 moves, the first gear 404 can be rotated. A limit rod 405 is installed at the bottom of the first gear 404, so that when the first gear 404 rotates, the limit rod 405 will also rotate synchronously. After the limit rod 405 rotates, it will be at the bottom of the fixed plate 5, so as to achieve the purpose of limiting the bottom plate 4. A synchronous toothed belt 304 is installed on the output shaft of the first motor 3, and the second synchronous pulley 302 and the third synchronous pulley 303 are also matched inside the synchronous toothed belt 304. The second synchronous pulley 302 is installed at one end of the cleaning roller 201. After the first motor 3 is started, the cleaning roller 201 can be rotated by the synchronous toothed belt 304.In order to make it possible to clean the photovoltaic panel 101 better, a support block 305 is installed on one side of the third synchronous pulley 303, and the support block 305 slides on the inner side of the inner shell 2, and springs 307 are installed on both sides of the support block 305, so that under the constraint of the spring 307, it can be ensured that the cleaning roller 201 can continue to rotate after being lifted, so that when the second motor 108 and the first motor 3 are started, the cleaning roller 201 can clean the photovoltaic panel 101. When the cleaning is completed, the outer shell 1 and the cleaning roller 201 will be reset, and when the cleaning roller 201 is reset, the bottom plate 4 will also When the cleaning roller 201 is used, the electric push rod 701 at the bottom of the guide plate 7 will be started, and a second rack 702 is installed at one end of the electric push rod 701, and the second rack 702 cooperates with the second gear 704 at the bottom of the third screw rod 703, so that when the second rack 702 moves, the third screw rod 703 can be rotated, and baffles 706 are installed on the surfaces of the two third screw rods 703. The baffle 706 initially closes the bottom of the guide plate 7 to prevent impurities from entering the device. Because the baffle 706 is installed on the surface of the third screw rod 703, when the third screw rod 703 rotates, the baffle 706 will also rotate accordingly to open the bottom of the guide plate 7. A scraper 705 is also installed on the top of the third screw rod 703, and the scraper 705 cooperates with the third screw rod 703. When the third screw rod 703 rotates, the scraper 705 can move up to make it contact with the cleaning roller 201. When the two are in contact, the first motor 3 will Start the cleaning roller 201 to rotate. Because the scraper 705 squeezes the cleaning roller 201, the impurities on the cleaning roller 201 can be cleaned when the cleaning roller 201 rotates to avoid damage to the photovoltaic panel 101 when it is used again. Two guide tubes 207 are installed inside the inner shell 2, and multiple nozzles 208 are installed on the surface of the two guide tubes 207. The nozzles 208 on the two guide tubes 207 spray the surface of the photovoltaic panel 101 and the surface of the cleaning roller 201 respectively to ensure that the photovoltaic panel 101 and the cleaning roller 201 can have better effects during the cleaning process.
