A construction method of a photovoltaic support according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1, construction preparation, pouring a concrete base (3) on the ground where the photovoltaic panel (2) is to be installed, then embedding the support column (4) into the top of the base (3), installing the photovoltaic panel (2) on the top of the support frame (1), and hinge the support frame (1) to the top of the support column (4) through a lifting device; S2, installing the adjustment assembly (7), hinge one end of the first connecting rod (71) and the second connecting rod (78) on one side of the bottom of the support frame (1), and then respectively install the first slide plate (72), the second slide plate (77) and the second screw rod (74) on the inner side of the slide groove (73), so that the second screw rod (74) is threadedly connected to the first slide plate (72), and the second slide plate (77) is slidably sleeved on the outer side of the second slide column (76); When the third motor (75) is working, the output shaft of the third motor (75) drives the second screw rod (74) to rotate. When the second screw rod (74) rotates clockwise, the first slide plate (72) drives the second slide plate (77) to move upward along the second slide column (76). The moving speed of the first slide plate (72) is 0.1-0.3 cm / s, so that one side of the photovoltaic panel (2) tends to a horizontal state. When the second screw rod (74) rotates counterclockwise, one side of the photovoltaic panel (2) tends to a vertical state. S3, the cleaning component (5) is installed, when the limit plate (510) and the first motor (512) are respectively installed on one side of the support frame (1), and the fixing frame (51) and the protective cover (56) are installed on one side of the connecting frame (57), the inside of the water tank (511) is filled with water, and the water outlet end of the water pump (516) is connected to the liquid inlet end of the liquid storage chamber (514) through a water pipe; When the output group of the second motor (513) drives the rotating shaft (53) to rotate, the rotating shaft (53) drives the multiple bristles (54) to rotate, and the rotating shaft (53) rotates at a speed of 50-200 r / min. At the same time, the water pump (516) transports the water inside the water tank (511) to the inside of the liquid storage chamber (514). After the water enters the inside of the liquid storage chamber (514), it is sprayed onto the surface of the photovoltaic panel (2) through the multiple water spray holes (55) under the action of the water delivery trough (515). Then, the output shaft of the first motor (512) drives the first screw rod (58) to rotate. The first screw rod (58) is threadedly connected to the connecting frame (57). The connecting frame (57) drives the bristles (54) to move back and forth along the first sliding column (59). Finally, the scraper (52) scrapes off the remaining dirt. S4, installing the photoresistor (6), installing the photoresistor (6) on one side of the top of the support frame (1), and installing the controller (8) on one side of the back of the support frame (1).
