[0044] Among them, the second drive motor 16 mentioned above can be purchased on the market. It is a mature technology and has been fully disclosed, so it is not repeated in the specification. The second drive motor 16 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or chemical power source) through the power line, and the main controller can be a conventional known device such as a computer that plays a control role.

[0045] As a technical optimization scheme of the present invention, the water collection unit 9 includes a water collecting box 20 arranged on the ground, a water collecting trough 21 is arranged on the support frame 3, the water collecting trough 21 is located below the lowest side of the photovoltaic panel body 2, a water collecting port 22 is opened at the lowest horizontal position in the water collecting trough 21, a water collecting pipe 23 connected to the water collecting port 22 and the water collecting box 20 is arranged, a pump body 25 is arranged in the water collecting box 20, and an elastic hose 24 is fixedly installed at one end of the pump body 25 and one end of the water pipe 7.
