When the photovoltaic support 21 rotates relative to the fixed shaft 11 within the second angle range, the guide pin 111 slides in the second section 442; the second transmission mechanism includes a swing rod 42 and a driving plate 45, the driving plate 45 is fixedly connected to the sliding sleeve 44, a waist-shaped hole 451 arranged along the second direction is provided on the driving plate 45, a first end of the swing rod 42 is fixedly connected to the first end of the swing arm 41, a pin shaft 43 is provided at a second end of the swing rod 42, and the pin shaft 43 and the waist-shaped hole 451 form a sliding fit.

[0033] Please refer to Figure 1-5As shown, in an alternative embodiment of the present invention, two of the photovoltaic panels 20 are provided on each of the photovoltaic brackets 21. The two photovoltaic panels 20 are arranged at intervals, and the slide rail 22 is located between the two photovoltaic panels 20. The driving mechanism includes a worm gear 52, a worm 51 and a servo motor (not shown in the figure). One of the worm gears 52 is respectively installed on each of the photovoltaic brackets 21. The worm 51 is rotatably connected to the frame 10. The servo motor is installed on the frame 10, and the output shaft of the servo motor is in transmission connection with the worm 51. Two sets of the linkage mechanisms are correspondingly arranged for each of the wiper strips 40, and the two sets of the linkage mechanisms are symmetrically arranged on both sides of the wiper strip 40.

[0034] In an alternative embodiment of the present invention, a sensor for detecting the sunlight irradiation angle is further included. The sensor and the servo motor are respectively electrically connected to a controller. In this embodiment, the photovoltaic panel 20 can automatically adjust the panel direction according to the sunlight irradiation angle, so that the sunlight can directly irradiate the photovoltaic panel 20 as much as possible, improving the power generation performance.

[0035] The specific working process and principle of the present invention are as follows:

[0036] First of all, it should be understood that the normal working angle of the photovoltaic panel 20 is about 90°, that is, the stroke of the panel from the vertical state to the horizontal state. After exceeding this stroke, the panel of the photovoltaic panel 20 will not be able to collect sunlight. The present invention exactly utilizes the non-working stroke of the photovoltaic panel 20 to drive the wiper strip 40 to move. When the photovoltaic panel 20 rotates to outside the working angle range, the rotation movement of the photovoltaic panel 20 itself is used to drive the wiper strip 40 to move, which not only simplifies the equipment structure and reduces the equipment cost, but also will not interfere with the normal working state of the photovoltaic panel 20. The specific principle is as follows: When the photovoltaic panel 20 rotates within the first angle range, that is, when the photovoltaic panel 20 is within the working angle range, the guide pin 111 is located in the first section 441 of the guide groove. At this time, the sliding sleeve 44 will not generate any displacement, so that the wiper strip 40 can be kept at the edge of the photovoltaic panel 20 and will not block the sunlight. When the photovoltaic panel 20 exceeds the working angle, that is, when the photovoltaic panel 20 rotates within the second angle range. For example, when the photovoltaic panel 20 rotates to the vertically upward state and then continues to flip backward, the guide pin 111 enters the second section 442 of the guide groove. At this time, the sliding sleeve 44 generates an axial displacement under the action of the spiral guide groove, thereby driving the wiper strip 40 to move. Before performing this operation, the surface of the photovoltaic panel 20 can be sprayed with clean water or cleaning agent by the spraying device 30 first. In this way, the surface of the photovoltaic panel 20 can be cleaned by the movement of the wiper strip 40. The present invention only needs to drive the photovoltaic panel 20 to rotate from beginning to end. By rotating the photovoltaic panel 20 within different angle ranges, the normal working of the photovoltaic panel 20 and the cleaning of the photovoltaic panel 20 are realized, without an additional power source, greatly simplifying the equipment structure and reducing the equipment cost.
