4. The windbreak and sand-fixing device according to claim 3, characterized in that: The length of the pitch device lead screw (1007) is more than twice the length of the rotating device support (906).

5. A windbreak and sand-fixing device according to any one of claims 1 to 4, characterized in that: Sand-proof sheets (104) are suspended in the mesh of the sand-blocking plate (102). The sand-proof sheets (104) can reduce the speed at which wind and sand pass through the mesh and at the same time block some sand from passing through the windproof and sand-fixing device.

6. A windbreak and sand-fixing device according to any one of claims 1 to 4, characterized in that: The sand baffle bracket (101) has a structure that is narrow at the top and wide at the bottom, and 3 to 6 layers of sand baffles (102) are provided on the sand baffle bracket (101).

7. A windbreak and sand-fixing device according to any one of claims 1 to 4, characterized in that: The lower end of the anchor leg (103) adopts a wedge-shaped plate structure, and the first foot plate (223) and the second foot plate (233) are wide-bottomed conical structures.

8. A windbreak and sand-fixing device according to any one of claims 1 to 4, characterized in that: The number of the first footplate (223) and the second footplate (233) is 8 to 12.

9. A windbreak and sand-fixing device according to any one of claims 1 to 4, characterized in that: The photovoltaic power generation module also includes a photosensitive element, which is used to guide the operation of the photovoltaic panel rotation device (90) and the photovoltaic panel pitch device (100) so that the photovoltaic panel (80) is always perpendicular to the light.
