2. The sand-blocking and wind-prevention system of the insert-plate type sand-blocking dike according to claim 1, characterized in that: The trapezoidal sand retaining wall (100) also has a first inclined wall (130) and a second inclined wall (140) connected to the upper bottom wall (110) and the lower bottom wall (120) at the same time, and the angle between at least one of the first inclined wall (130) and the second inclined wall (140) and the lower bottom wall (120) is set to 30°-35°.

3. The sand-blocking and wind-prevention system of the insert-plate type sand-blocking dike according to claim 1, characterized in that: A slot (150) is provided on the upper bottom wall (110), and the side of the first plate (210) away from the second plate (220) is inserted into the slot (150).

4. The sand-blocking and wind-prevention system of the insert-plate type sand-blocking dike according to claim 3, characterized in that: The slot (150) is also provided with anti-dislodgement insertion holes (160) on the slot side wall. The sandstorm baffle (200) further includes an anti-detachment component (230), which is installed on the first plate (210). The anti-detachment component (230) has a first state and a second state that can be switched between each other. When it is in the first state, the anti-detachment component (230) is inserted into the anti-detachment socket (160) to prevent the sandstorm baffle (200) from disengaging from the slot (150). When it is in the second state, the anti-detachment component (230) is separated from the anti-detachment socket (160) to release the locking of the sandstorm baffle (200) and the trapezoidal sand retaining wall (100).

5. The sand-blocking and wind-prevention system of the insert-plate type sand-blocking dike according to claim 4, characterized in that: The anti-detachment component (230) includes an anti-detachment insert (231), an elastic element (232), and a force transmission element (233); the first plate (210) is provided with an assembly through hole, the assembly through hole having a first hole section (214) and a second hole section (215) that are interconnected, the end of the first hole section (214) away from the second hole section (215) extends to a plate surface of the first plate (210), and the end of the second hole section (215) away from the first hole section (214) extends to the first plate (210). On one side of the 0), the anti-detachment rod (231) is slidably installed in the first hole section (214); the elastic element (232) is connected to both the anti-detachment rod (231) and the trapezoidal sand retaining wall (100) to make the anti-detachment rod (231) have a tendency to extend out of the first hole section (214); the force transmission element (233) is rotatably installed in the second hole section (215) and the force transmission element (233) is used to drive the anti-detachment rod (231) to retract into the first hole section (214).

6. The sand-blocking and wind-prevention system of the insert-plate type sand-blocking dike according to claim 5, characterized in that: The anti-detachment rod (231) is provided with a guide slope (2311), which is used to contact the edge of the groove sidewall so that when the guide slope (2311) contacts the edge of the groove sidewall, the anti-detachment rod (231) is driven back into the first hole section (214) by the edge of the groove sidewall.

7. The sand-blocking and wind-prevention system of the insert-plate type sand-blocking dike according to claim 5, characterized in that: The force transmission component (233) includes a rod body (2331) and an eccentric head (2332). The eccentric head (2332) is fixed to the rod body (2331). The rod body (2331) is rotatably connected to the second hole section (215), and the rod body (2331) does not protrude from the port of the second hole section (215). An operating groove is provided on the end face of the rod body (2331) near the port of the second hole section (215).

8. The sand-blocking and wind-prevention system of the insert-plate type sand-blocking dike according to any one of claims 1-7, characterized in that: The porosity of the first plate (210) is set to 0.45-0.

51.

9. The sand-blocking and wind-prevention system of the insert-plate type sand-blocking dike according to any one of claims 1-7, characterized in that: The included angle between the first plate (210) and the second plate (220) is set to 65°-75°.

10. The sand-blocking and wind-prevention system of the insert-plate type sand-blocking dike according to any one of claims 1-7, characterized in that: The shape of the ventilation hole (211) is set to polygonal, circular or elliptical.
