[0002] A photovoltaic (PV) panel (also known as a solar panel) is a semiconductor device that directly converts solar energy into electrical energy. Its core principle is the photovoltaic effect. It is mainly composed of silicon-based solar cells, glass, EVA film, and a backsheet, and is widely used in clean energy power generation systems. PV panels are typically installed outdoors, and dust and impurities accumulate on their surfaces. Over time, this dust buildup can block sunlight, reducing the absorption of solar radiation and lowering photoelectric conversion efficiency. Therefore, regular cleaning of PV panels is necessary.

[0022] Example 1:

[0023] like Figure 1-6 As shown, an automatic cleaning device for photovoltaic panels includes a cleaning vehicle 1.

Two guide rods 32 are symmetrically fixedly installed on the front of the connecting plate 33. The outer walls of the two guide rods 32 are symmetrically slidably connected to the inside of the fixed frame 3. The electric telescopic rod 31 facilitates the movement of the connecting plate 33. The connecting plate 33 can also drive the two guide rods 32 to move inside the fixed frame 3. The two guide rods 32 can be used to guide the connecting plate 33 horizontally.

[0024] A mounting groove 331 is provided on the back of the connecting plate 33. A low-speed motor 332 is fixedly mounted on the top of the inner wall of the mounting groove 331. A lead screw 333 is fixedly mounted on the output end of the low-speed motor 332 via a coupling. The bottom end of the lead screw 333 is rotatably mounted on the bottom of the inner wall of the mounting groove 331 via a bearing. A positioning block 334 is threadedly connected to the lower part of the outer wall of the lead screw 333. The outer wall of the positioning block 334 is slidably connected to the inside of the mounting groove 331. A connecting frame 335 is hinged to the back of the positioning block 334.

A limiting frame 336 is fixedly installed, and a connecting shaft 337 is fixedly installed inside the limiting frame 336. A support block 338 is fixedly installed on the lower front of the movable seat 34. The inside of the support block 338 is rotatably sleeved on the outer wall of the connecting shaft 337. When the connecting plate 33 moves, it can synchronously drive the movable seat 34 to move, which can move the movable seat 34 to the photovoltaic panel. Through the cooperation of the low-speed motor 332, the lead screw 333, the positioning block 334 and the connecting frame 335, it is easy to drive the upper part of the movable seat 34 to move. The lower part of the movable seat 34 rotates around the connecting shaft 337, so that the movable seat 34 has a certain tilt angle, which facilitates the subsequent cleaning of the photovoltaic panel.

[0025] A conduit 35 is fixedly installed on one side of the rear of the mobile base 34. Multiple nozzles 351 are fixedly installed on the conduit 35. A water pump 4 is fixedly installed on one side of the top of the cleaning vehicle 1. A water tank 2 is fixedly installed on the top of the cleaning vehicle 1. A connecting pipe 5 is fixedly connected to the lower right side of the water tank 2. A solenoid valve 6 is installed on the connecting pipe 5.

With the water tank 2, a large amount of water can be loaded. With the water pump 4 and the connecting pipe 5, the water inside the water tank 2 can be pumped out and discharged into the conduit 35 through the hose 352. At the same time, multiple nozzles 351 are used to spray water onto the surface of the photovoltaic panel, which is convenient for cleaning the photovoltaic panel.

[0026] Example 2:

[0027] like Figure 1-6 As shown, a mounting plate 38 is provided on the other side of the rear of the movable seat 34. A sub-hook and loop fastener is fixedly installed on the back of the mounting plate 38. A female hook and loop fastener is glued to the back of the sub-hook and loop fastener. A sponge strip 39 is fixedly connected to the back of the female hook and loop fastener. A second electric telescopic rod 36 is fixedly installed on the front of the movable seat 34. The telescopic end of the second electric telescopic rod 36 extends to the rear of the movable seat 34 and is fixedly installed in the middle of the front of the mounting plate 38. Two second guide rods 37 are symmetrically fixedly installed on the front of the mounting plate 38. The outer wall of the second guide rod 37 is slidably connected to the inside of the movable seat 34. A waterproof power box 7 is fixedly installed on one corner of the top right of the cleaning engineering vehicle 1. A battery is installed inside the waterproof power box 7.

[0028] In this embodiment, when the movable seat 34 moves and adjusts its angle, it can simultaneously move the sponge strip 39, positioning the sponge strip 39 above the photovoltaic panel. Through the cooperation of the second electric telescopic rod 36 and the second guide rod 37, the mounting plate 38 and the sponge strip 39 can be smoothly moved, allowing the sponge strip 39 to overlap the surface of the photovoltaic panel. When the cleaning vehicle 1 is in motion, the sponge strip 39 can wipe the surface of the photovoltaic panel, improving its cleanliness. The mounting plate 38 and the sponge strip 39 are connected by Velcro, facilitating the disassembly and replacement of the sponge strip 39. The battery inside the waterproof power box 7 can power the electrical equipment in this application, enabling the equipment to operate outdoors.

[0029] In summary, as Figure 1-6As shown, this automatic cleaning equipment for photovoltaic panels operates by first parking the cleaning vehicle 1 near the photovoltaic panel. Then, the connecting plate 33 and the movable seat 34 are moved via the telescopic end of the first electric telescopic rod 31, causing the movable seat 34 to move above one side of the photovoltaic panel. Simultaneously, the output end of the low-speed motor 332 drives the lead screw 333 to rotate. The lead screw 333 causes the positioning block 334 to slide inside the mounting groove 331. The positioning block 334 also causes the bottom end of the connecting frame 335 to move upwards. At this time, the top end of the connecting frame 335 causes the upper part of the movable seat 34 to move upwards, and the lower part of the movable seat 34 causes the support block 338 to rotate on the outer wall of the connecting shaft 337, causing the movable seat 34 to tilt at a certain angle. This tilts the movable seat 34, the nozzle 351, and the sponge strip 351. 9 is in a relatively parallel state with the surface of the photovoltaic panel. Then, the extension end of the second electric telescopic rod 36 drives the installation plate 38 and the sponge strip 39 to move, so that the sponge strip 39 overlaps the surface of the photovoltaic panel. At this time, the solenoid valve 6 and the water pump 4 are turned on, and the water inside the water tank 2 is drawn out by the connecting pipe 5 and the water pump 4 and discharged into the conduit 35 through the hose 352. At the same time, water is sprayed on the surface of the photovoltaic panel through multiple nozzles 351 to clean the photovoltaic panel. Then, the cleaning engineering vehicle 1 drives the nozzles 351 and the sponge strip 39 to move. The movement of the nozzles 351 can quickly clean multiple photovoltaic panels arranged in a horizontal row, and the sponge strip 39 is used to wipe the surface of the photovoltaic panel to further clean the surface of the photovoltaic panel, thus facilitating and quickly cleaning the surface of the photovoltaic panel.
