Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic system cleaning device. Background Art

[0002] Solar energy is generated by the continuous nuclear fusion reactions within or on the surface of the sunspots. Solar energy boasts abundant resources, longevity, widespread distribution, safety, cleanliness, and reliable technology. Because solar energy can be converted into a variety of other forms of energy, it has a wide range of applications. To generate electricity from solar energy, solar cells perform photoelectric conversion.

[0003] Many commercial and industrial rooftops are currently equipped with photovoltaic power generation systems. These systems require regular cleaning of dust and dirt to prevent them from affecting their effective power output. Existing cleaning robots require three to five days to clean the entire area covered by photovoltaic panels, making them inefficient. Traditional cleaning methods are infrequent (occasionally cleaning every few months). However, the longer the interval between cleanings, the more dust and dirt accumulate, reducing the panel's power generation. (In some areas, power generation decreased by 50% or more just one month after cleaning.) Furthermore, the longer the cleaning interval, the more difficult it is to remove dust and dirt. Therefore, ensuring thorough cleaning requires a higher level of intelligence in the robot, which in turn leads to a higher price tag (ranging from several thousand to tens of thousands of yuan). Summary of the Invention

The two steel wire rope groups are wound on the output end of the drive motor and, driven by the drive motor, drive the water spray frame to move along the photovoltaic panel unit.

[0006] As a further improvement of the above technical solution: The winding directions of the two steel rope groups on the output end of the driving motor are opposite.

[0007] The wire rope group includes a wire rope and a fixed pulley. The fixed pulley is arranged on a bracket at the rear end of the photovoltaic system. One end of the wire rope is connected to the front end of one side of the spray frame, and the other end is connected to the rear end of the other side of the spray frame after being wound around the fixed pulley.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 4As shown, the photovoltaic system cleaning device of this embodiment comprises a photovoltaic panel unit 1 and a bracket 2, each photovoltaic panel unit 1 being supported on the bracket 2. The cleaning device comprises a water spray frame 3, a drive motor 4, and two steel wire rope groups 5. The two steel wire rope groups 5 are connected to the water spray frame 3 end to end, with the connection points located at both ends of the water spray frame 3. The two steel wire rope groups 5 are wound around the output end of the drive motor 4 and, driven by the drive motor 4, drive the water spray frame 3 to move along the photovoltaic panel unit 1. The present invention uses the two steel wire rope groups 5 wound around the drive motor 4 to pull the water spray frame 3 to move. No other transmission parts are required between the drive motor 4 and the water spray frame 3, simplifying the structure of the cleaning device, reducing costs, and facilitating installation.

[0021] In this embodiment, the two steel rope groups 5 are wound in opposite directions on the output end of the drive motor 4. The steel rope group 5 includes a steel rope 51 and a fixed pulley 52. The fixed pulley 52 is mounted on the bracket 2 at the rear end of the photovoltaic system. One end of the steel rope 51 is connected to the front end of one side of the spray rack 3, and the other end is connected to the rear end of the other side of the spray rack 3 after being wound around the fixed pulley 52. In this structure, the two steel ropes 51 are wound in opposite directions on the output end of the drive motor 4, so that when the drive motor 4 is running, the two steel ropes 51 move in opposite directions. The steel ropes 51 are reversed by the fixed pulley 52, so that the two steel ropes 51 at the front and rear ends of one side of the spray rack 3 move in the same direction. The structure is simple and the design is ingenious.

[0022] In this embodiment, the cleaning device further includes two reversing pulley assemblies 6, each of which is disposed on a bracket 2 at the front end of the photovoltaic system. The reversing pulley assemblies 6 include an upper pulley 61 and a lower pulley 62. Two steel ropes 51 are respectively wound around the upper pulley 61 or the lower pulley 62 of the two reversing pulley assemblies 6. In this embodiment, the steel ropes 51 are wound around the upper pulley 61 of one reversing pulley assembly 6 and the lower pulley 62 of the other pulley assembly 6. The two steel ropes 51 cross each other on the two reversing pulley assemblies 6. This arrangement ensures that the steel ropes 51 are subjected to balanced force when pulling the water spraying frame 3, maintaining smooth movement of the water spraying frame 3.

[0023] In this embodiment, the water spray frame 3 includes a support base 31 and a water spray pipe 32. The water spray pipe 32 is fixed on the support base 31, and the wire rope 51 is connected to the support base 31. The water spray pipe 32 is used for the simplest flushing and cleaning, which has a simple structure and low cost.

[0024] In this embodiment, a plurality of nozzles 321 are distributed on one side of the water spray pipe 32 facing the photovoltaic panel unit 1. The plurality of nozzles 321 are provided to improve the cleaning effect.

[0025] In this embodiment, the support base 31 is provided with a roller 33 that is slidably connected to the photovoltaic panel unit 1. The roller 33 is slidably connected to the photovoltaic panel unit 1 to facilitate movement.

[0026] In this embodiment, a brush head 34 for cleaning the photovoltaic panel unit 1 is further provided on the support base 31. In this structure, the provision of the brush head 34 further improves the cleaning effect.
