Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning technology, specifically to a photovoltaic panel cleaning device. Background Technology

[0002] A photovoltaic (PV) panel (solar panel) is a device that converts solar energy into electrical energy. It consists of multiple photovoltaic cell units, and the core material is mostly silicon semiconductor. When sunlight shines on it, photons interact with electrons in the semiconductor to generate direct current (DC). This DC power can be converted into alternating current (AC) power by an inverter for daily use. Types include monocrystalline silicon (high efficiency but high cost), polycrystalline silicon (balanced cost-effectiveness), and thin-film batteries (lightweight but lower efficiency). Chinese patent publication number CN 219204450 U discloses a photovoltaic panel cleaning device, which includes an installation mechanism movably installed at both ends of the photovoltaic panel. The installation mechanism has two sets, and a spray component, a cleaning component, and a wiping component are slidably arranged between the two sets of installation mechanisms. The installation mechanism includes a mounting frame and a clamping frame. The clamping frame is slidably arranged in the mounting frame, and a return spring abuts between the mounting frame and the clamping frame.

[0003] In the above technical solution, a photovoltaic panel cleaning device can spray cleaning liquid onto the photovoltaic panel and roll it for cleaning. However, the cleaning roller is made of flexible cloth and is directly installed on the output end of the rotary motor, making it inconvenient to disassemble. After a period of use, a lot of dirt will stick to the surface of the cleaning roller, so it needs to be disassembled for maintenance. Otherwise, it will affect the quality of subsequent photovoltaic panel cleaning.

[0004] Therefore, a photovoltaic panel cleaning device is proposed. Utility Model Content

[0025] like Figure 1-3As shown, a photovoltaic panel cleaning device includes two fixed frames 1 and a cleaning roller 7. Mounting plates 2 are provided on the surfaces of both fixed frames 1. A moving mechanism 3 for lateral movement is provided on each fixed frame 1. A lifting mechanism 4 for height adjustment is provided on the moving mechanism 3. A sprayer 5 is provided on the lifting mechanism 4. A water supply component 6 is provided on the moving mechanism 3 and mounted on the sprayer 5. An installation mechanism 8 for convenient installation and fixing of the cleaning roller 7 is provided on the lifting mechanism 4, and the cleaning roller 7 is mounted on the installation mechanism 8. A drive mechanism 9 for rotating the cleaning roller 7 is provided on the installation mechanism 8. A scraper 10 is provided on the lifting mechanism 4. In this embodiment, the water supply component 6 is composed of a water tank, a water pump, and water pipes. During use, the mounting plate 2 is fixed to the photovoltaic panel bracket by bolts. The height of the sprayer 5, cleaning roller 7, and scraper 10 is adjusted by the lifting mechanism 4. Both the cleaning roller 7 and the scraper 10 are in contact with the photovoltaic panel. At this time, water can be supplied to the sprayer 5 through the water supply component 6, and then sprayed outward from the sprayer 5 onto the photovoltaic panel to soften the dust. The drive mechanism 9 drives the cleaning roller 7 to rotate, which rolls and cleans the photovoltaic panel sprayed with water. The moving mechanism 3 can move the sprayer 5, cleaning roller 7, and scraper 10. With the cooperation of the sprayer 5 and the cleaning roller 7, the dust on the surface of the photovoltaic panel is cleaned by moving. The scraper 10 moves to remove water stains from the photovoltaic panel after cleaning. After the cleaning roller 7 has been used for a period of time, it can be disassembled by the installation mechanism 8 for maintenance or replacement. This makes it easy to install and replace the cleaning roller 7 and remove water stains after cleaning the photovoltaic panel. The operation is simple and practical.

[0026] like Figure 1-2 As shown, the moving mechanism 3 includes a one-way screw 301, which is rotatably installed inside the front fixed frame 1. A cylinder 302 is fixedly installed inside the rear fixed frame 1. A moving frame 303 is threaded onto the outer wall of the one-way screw 301 and slides on the outer wall of the cylinder 302. A motor 304 is fixedly installed on the surface of the front fixed frame 1, and the one-way screw 301 is fixedly installed at the output end of the motor 304. In this embodiment, the motor 304 is started, which drives the one-way screw 301 to rotate, causing the moving frame 303 to move laterally, thereby adjusting the position of the moving frame 303.

[0027] like Figure 1-2 As shown, the lifting mechanism 4 includes two cylinders 401. The cylinders 401 are fixedly mounted on the top of the movable frame 303. The telescopic ends of the cylinders 401 are slidably mounted on the movable frame 303. The telescopic ends of the two cylinders 401 are fixedly mounted with lifting plates 402. In this embodiment, the two cylinders 401 are activated to drive the lifting plates 402 to move longitudinally, thereby adjusting the height of the lifting plates 402.

[0028] like Figure 2-3 As shown, the mounting mechanism 8 includes a sliding plate 804. The bottom of the lifting plate 402 is provided with a sliding groove, and the sliding plate 804 is slidably mounted on the inner wall of the sliding groove. A rectangular plate 805 is fixedly mounted on the bottom of the lifting plate 402. A T-shaped stud 806 is threaded onto the rectangular plate 805, and the T-shaped stud 806 is rotatably mounted on the sliding plate 804. A knob 807 is fixedly mounted on the surface of the T-shaped stud 806. In this embodiment, by rotating the knob 807 in the forward direction, the T-shaped stud 806 is driven to rotate and move, pushing the sliding plate 804 to slide in the sliding groove. Conversely, by rotating the knob in the reverse direction, the sliding plate 804 is pulled to slide in the sliding groove, thereby adjusting the position of the sliding plate 804.

[0029] like Figure 3-4 As shown, a fixed plate 801 is fixedly installed at the bottom of the lifting plate 402. A cross shaft 802 is rotatably installed on the fixed plate 801. A connecting block 803 is fixedly installed on the surface of the cross shaft 802. A hexagonal block is fixedly installed on one side of the sweeping roller 7. A hexagonal groove is opened on the surface of the connecting block 803, and the hexagonal block is slidably installed on the inner wall of the hexagonal groove. A round block is fixedly installed on one side of the sweeping roller 7. A round groove is opened on the surface of the sliding plate 804, and the round block is slidably installed on the inner wall of the round groove. In this embodiment, when the hexagonal block on the sweeping roller 7 is inserted into the hexagonal groove, and the T-shaped stud 806 pushes the sliding plate 804 to move, the round block on the sweeping roller 7 will be inserted into the round groove, thus completing the clamping and fixing of the sweeping roller 7.

[0030] like Figure 3-4 As shown, the drive mechanism 9 includes a second motor 901, which is fixedly mounted on the top of the lifting plate 402. Both the cross shaft 802 and the output end of the second motor 901 are fixedly mounted with synchronous pulleys 902. Synchronous belts 903 are meshed on the outer walls of the two synchronous pulleys 902. In this embodiment, when the second motor 901 is started, it drives the synchronous pulleys 902 connected to it to rotate. With the cooperation of the synchronous belts 903, the two synchronous pulleys 902 rotate synchronously. Therefore, the cross shaft 802, the connecting block 803, the hexagonal block, the cleaning roller 7 and the round block rotate synchronously. The cleaning roller 7 can roll and clean the photovoltaic panel.

[0031] In summary, the water supply assembly 6 comprises a water tank, a water pump, and water pipes. During use, the mounting plate 2 is fixed to the photovoltaic panel bracket with bolts. The height of the sprayer 5, cleaning roller 7, and scraper 10 is adjusted via the lifting mechanism 4. Both the cleaning roller 7 and scraper 10 are in contact with the photovoltaic panel. Water is supplied to the sprayer 5 via the water supply assembly 6, and then sprayed onto the photovoltaic panel to soften dust. The drive mechanism 9 rotates the cleaning roller 7, which then rolls and cleans the sprayed photovoltaic panel. The moving mechanism 3 allows the sprayer 5, cleaning roller 7, and scraper 10 to move. The sprayer 5 and cleaning roller 7 work together to clean the dust on the photovoltaic panel surface, while the moving scraper 10 removes water stains from the cleaned panel. After a period of use, the cleaning roller 7 can be disassembled via the mounting mechanism 8 for maintenance or replacement. This facilitates the installation and replacement of the cleaning roller 7 and the removal of water stains after cleaning the photovoltaic panel. The operation is simple and highly practical. Motor 304 drives the one-way screw 301 to rotate, causing the moving frame 303 to move laterally, thereby adjusting the position of the moving frame 303. Two cylinders 401 are activated, driving the lifting plate 402 to move longitudinally, thereby adjusting the height of the lifting plate 402. Rotating the knob 807 in the forward direction drives the T-screw 806 to rotate and move, pushing the sliding plate 804 to slide within the groove. Conversely, rotating it in the reverse direction pulls the sliding plate 804 to slide within the groove, thereby adjusting the position of the sliding plate 804. When the hexagonal block on the cleaning roller 7 is inserted into the hexagonal groove, and the T-shaped stud 806 pushes the sliding plate 804 to move, the round block on the cleaning roller 7 will be inserted into the round groove, thus completing the clamping and fixing of the cleaning roller 7. The motor 901 is started, which drives the synchronous wheel 902 connected to it to rotate. With the cooperation of the synchronous belt 903, the two synchronous wheels 902 rotate synchronously. Therefore, the cross shaft 802, the connecting block 803, the hexagonal block, the cleaning roller 7 and the round block rotate synchronously, and the cleaning roller 7 can roll and clean the photovoltaic panel.
