Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic technology, specifically relating to a dust removal device for photovoltaic panels. Background Technology

[0002] Solar photovoltaic devices are currently widely used power generation equipment. They convert solar energy into electrical energy through photovoltaic panels, which not only saves energy and reduces emissions, but also effectively prevents the over-exploitation and use of non-renewable energy.

[0003] Photovoltaic panels are generally installed outdoors, mostly on unused slopes in the suburbs. After long-term use, a lot of dust will accumulate on the photovoltaic panels, which will significantly reduce the solar energy absorption efficiency of the photovoltaic panels. Therefore, it is necessary to clean the photovoltaic panels regularly to keep their surfaces clean. To this end, we propose a photovoltaic panel dust removal device. Utility Model Content

[0004] The purpose of this invention is to provide a dust removal device for photovoltaic panels, which effectively cleans the dust on the surface of photovoltaic panels and ensures the effectiveness of photovoltaic panels in absorbing light energy.

[0005] The technical solution adopted by this utility model is a photovoltaic panel dust removal device, including an upper end frame and a lower end frame installed on both sides of the photovoltaic panel. The upper end frame and the lower end frame on the same side are respectively rotatably connected to the lead screws through bearing seats. The top ends of the two lead screws extend out of the bearing seats and are connected to the drive motor. Two lead nuts that match the lead screws are respectively connected to the two lead screws and slide along them. A connecting rod is bolted between the two lead nuts. The connecting rod is located above the photovoltaic panel. A mounting frame is provided below the connecting rod. A roller brush is installed at the front end of the mounting frame and a cleaning wheel is installed at the rear end. Both the roller brush and the cleaning wheel are in contact with the surface of the photovoltaic panel.

[0006] Preferably, a water tank is provided between the two upper frames, and a water spray pipe is provided on the side of the water tank facing the photovoltaic panel. The head of the water spray pipe is connected to a water pump, and multiple nozzles are provided at intervals on the water spray pipe.

[0007] Preferably, the mounting frame is in the shape of an inverted T, with mounting plates on both sides of the front end of the mounting frame facing downwards. The mounting plates are connected to rollers by a rotating shaft, and the rollers are provided with brushes or adhesive brushes on their surfaces, which are in frictional contact with the photovoltaic panels.

[0008] Preferably, multiple rotating motors are installed at intervals at the rear end of the mounting frame. The top of the rotating motor is fixedly connected to the mounting frame via a mounting base. The output shaft of the rotating motor extends downward to connect to the cleaning disc, and a mop is provided on the cleaning disc.

[0009] Preferably, the mop is made of cotton or sponge and is bonded to the cleaning disc.

[0010] Compared with the prior art, the beneficial effects of this utility model are that the photovoltaic panel dust removal device designed in this utility model drives the lead screw to rotate through the drive motor, which drives the lead screw nut to move up and down along the lead screw, thereby causing the roller brush to roll and rub against the photovoltaic panel to clean the dust on the surface of the photovoltaic panel. At the same time, the rotation of the motor causes the cleaning wheel to rotate and continuously wipe away the dust. After the roller brush and cleaning wheel have reciprocated once, the water spray pipe sprays water onto the photovoltaic panel through multiple nozzles, and then another cleaning cycle is performed to ensure that the surface of the photovoltaic panel is clean and improve the quality of the photovoltaic panel's absorption of light energy.

The top ends of the two lead screws 5 extend out of the bearing seats 4 and are connected to drive motors 6. The drive motors 6 are installed on the upper frame 2. Two nuts 7 that match the lead screws 5 are respectively connected to the two lead screws 5 and slide along them. A connecting rod 8 is bolted between the two nuts 7. The connecting rod 8 is located above the photovoltaic panel 1. A mounting frame 9 is provided below the connecting rod 8. A roller brush 10 is installed at the front end of the mounting frame 9, and a cleaning wheel 11 is installed at the rear end.

The head of the water spray pipe 13 is connected to a water pump, and multiple nozzles 14 are provided on the water spray pipe 13 at intervals. The drive motor 6 drives the lead screw 5 to rotate, which drives the lead screw nut 7 to move up and down along the lead screw 5, so that the roller brush 10 and the cleaning wheel 11 clean the photovoltaic panel 1 in turn to remove surface dust and keep it clean.

[0018] Furthermore, the aforementioned mounting frame 9 is in the shape of an inverted T.
