[0016] The present invention has the following beneficial effects:

[0017] (1) The present invention is a photovoltaic power generation device, which connects a water inlet pipe to an external water tank. When the water inlet pipe is connected to the external water tank, the motor is turned on, and the motor drives the cleaning vehicle to move along the photovoltaic panel placement rack. At the same time, the cleaning cotton contacts the surface of the photovoltaic panel. When the cleaning cotton squeezes the surface of the photovoltaic panel, the cleaning cotton pushes the outer shell to move upward. When the outer shell moves upward, it pushes the diverter barrel to move upward. When the diverter barrel moves upward, it pushes the push rod to move upward. When the push rod moves upward, it pushes the circular water spray hose upward and expands. At the same time, when the water flow hits the fan barrel, it drives the fan barrel to move upward. When the fan barrel rotates, it will drive the round barrel to rotate, and when the round barrel rotates, it will drive the diverter barrel to rotate, and when the diverter barrel rotates, it will drive the connecting rod to rotate, and when the connecting rod rotates, it will drive the circular water spray hose to rotate, so that the device can rotate and spray water, and at the same time expand the water pipe to increase the diffusion range of the cleaning liquid and water. During the spraying process, the dust on the surface of the photovoltaic panel can be washed away, and the cleaning liquid and water can be evenly distributed, so that in the subsequent wiping of the photovoltaic panel, the cleaning effect of the device is improved, thereby improving the cleanliness of the photovoltaic panel and improving the power generation efficiency of the photovoltaic panel.

[0018] (2) The present invention is a photovoltaic power generation device. When water flows into the device along the water inlet pipe, the water flow will impact the fan barrel, thereby causing the fan barrel to rotate. When the fan barrel rotates, it will drive the slider to rotate. When the slider rotates, it will move up and down along the two-way threaded shaft. When the slider moves up and down, it will drive the tilting rod to rotate up and down. When the tilting rod moves up and down, it will push the ring to move up and down. When the ring moves up and down, it will push the connecting rod 1 back and forth. When the connecting rod 1 is pushed back and forth, it will push the connecting rod 2 back and forth in the direction of the circular water spray hose, so that the circular water spray hose can continue to expand and contract, so that the circular water spray hose can produce different flushing angles and strengths when spraying water, which is helpful to better remove the wind and sand on the surface of the photovoltaic panel. At the same time, it can also make the cleaning liquid and water more comprehensively cover the surface of the photovoltaic panel, ensuring that every corner can be cleaned, thereby further improving the cleaning effect, ensuring the efficient and stable operation of the photovoltaic power station, and further improving the power generation efficiency of the photovoltaic power station.

[0019] (3) The present invention is a photovoltaic power generation device. When the water flow impacts the fan barrel 1 and drives the round barrel to rotate, the round barrel will drive the diverter barrel to rotate. When the diverter barrel rotates, it will drive the outer shell to rotate. When the outer shell rotates, it will drive the slider 1 to move up and down along the C-shaped rod. When the slider 1 moves back and forth along the C-shaped rod, it will drive the inner shell to rotate in the opposite direction. When the outer shell rotates, it will drive the baffle to rotate. When the baffle rotates, it will drive the soft rod to rotate. When the soft rod rotates, it will drive the external cleaning cotton to rotate. At the same time, when the inner shell rotates in the opposite direction, it will drive the bottom gear to rotate. The square frame rotates in the opposite direction, and the gear rotates, which drives the pull rod to be pulled repeatedly. When the pull rod is pulled repeatedly, it drives the gear inside the square frame to be pulled repeatedly. When the square frame is pulled repeatedly, the tooth column inside the square frame drives gear one to rotate repeatedly, so that the cleaning cotton rotates repeatedly, and the cleaning cotton rubs the surface of the photovoltaic panel repeatedly. During the rubbing, the wind and sand deposited on the surface of the photovoltaic panel are effectively cleaned, so that the cleanliness of the surface of the photovoltaic panel is improved, the deposited wind and sand are prevented from affecting the direct exposure to the sun, the damage to the photovoltaic panel by the wind and sand is reduced, and the service life of the photovoltaic panel is further improved.
