[0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a new energy power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two modes of independent operation and grid-connected operation.

The jet assembly is connected to a three-way pipe through a bearing rotation. The airflow is injected into the three-way pipe by a fan, and the airflow will pass through the three-way pipe and the jet assembly.

[0028] Working principle: Start the hair dryer 4 and send it to the exhaust port 6 through the air duct 5 to dissipate heat and remove dust from the photovoltaic panel 1. The filter plate 7 filters the air blown into the air duct 5. When the filter plate 7 needs to be removed, first pull the handle 15 to drive the pull rod 12 to move, thereby driving the block 11 to leave the slot 9 through the pull rod 12, so that the filter plate 7 loses its fixation, and the filter plate 7 can be removed for cleaning or replacement. When the cleaning is completed or a new filter plate 7 is installed, first pull the handle 15 to make the block 11 enter the limit slot 10. When it is installed in the correct position, release the force on the handle 15, so that the spring 13 releases the tension and the block 11 is stuck in the slot 9, so that the filter plate 7 can be fixed in the air duct 5, and the installation is completed.

[0029] When the height of the photovoltaic panel 1 needs to be adjusted, the motor 22 is started to drive the bidirectional threaded rod 23 to rotate. When the bidirectional threaded rod 23 rotates, it will drive the two connecting plates 24 to move in opposite directions. When the connecting plate 24 moves, it will drive the slider 2 19 at both ends of the connecting plate 24 to move, and the slider 18 is made to slide at the bottom of the lifting plate 3 through the articulated frame 20. Because the opening and closing angle of the articulated frame 20 changes, the vertical height of the articulated frame 20 changes, and the height of the photovoltaic panel 1 changes, so that the height of the photovoltaic panel 1 can be adjusted.
