In this embodiment, the overall structure of the combined and installed mirror body and frame is approximately a symmetrical structure, and the center of gravity is located near the center of gravity, and the overall structure can be adjusted from a horizontal state to a vertical state, i.e. the angle adjustment range of the mirror body is 0-90 °. The angle of the lens body needs to be adjusted to change the motion state of the whole structure, and as the mass of the whole structure is often larger, especially for medium and large heliostats, the change of the motion state of the whole structure needs to provide larger driving force for the telescopic rod 6, and the power requirement on a device for driving the telescopic rod 6 is higher.
In this embodiment, the main beam circular tube 4 is installed on one side of the frame, which is deviated from the center of the frame, so that the main beam circular tube 4 is located on one side of the central axis of the overall structure. The integral structure is driven to rotate through the rotation of the main beam circular tube 4, namely, the integral structure rotates around the central shaft of the main beam circular tube 4.

The telescopic rod 6 of the embodiment is connected with the connecting arm 12 on one side of the main beam circular tube 4 far away from the center of the frame, and when the overall structure is in a horizontal state, the telescopic rod 6 is in a contracted state. Thus, when the telescopic rod 6 is extended, the gravity on one side connected with the telescopic rod 6 is smaller than that on the other side, so that the gravity and the driving force provided by the telescopic rod 6 drive the integral structure to rotate together in the process of adjusting the integral structure from the horizontal state to the vertical state. Because the dead weight of the integral structure participates in acting, the output power of the telescopic rod 6 is reduced, and meanwhile, the angle adjustment of the heliostat is more convenient and flexible.
