Water-absorbing cotton 5 is arranged in the drain pipe 3 to block the rainwater, so that the rainwater seeps out slowly, thereby extending the use time of the rainwater. Through the above process, the existing device for fixing sand dunes in the edge of the desert is solved. When sand barriers are used to fix sand, the problem of difficulty in storing rainwater in the rainy season and causing rainwater loss is solved due to the lack of water storage function of the sand barriers.
[0024] Furthermore, a top plate 8 is fixed between the two fixed plates 7, and a plurality of first water inlet grooves 9 are provided on the top surface of the top plate 8.

When it rains, rainwater enters through the through groove 14 on the first protective cover 10, and the high-temperature resistant water-swellable waterstop strip 15 expands after absorbing water, thereby pushing the movable plate 12 to move, so that the second water inlet trough 13 on the movable plate 12 is aligned with the first water inlet trough 9 on the top plate 8. At the same time, the movable plate 12 drives the movable baffle 17 to move, so that the first drainage groove 18 on the movable baffle 17 is aligned with the second drainage groove 20 on the side plate 19. Rainwater passes through the second water inlet trough 13 and the first water inlet trough 9 into the water tank 1, and the dust washed off the filter screen 6 is discharged from the first drainage groove 18 and the second drainage groove 20.
