[0025] The last paragraph constitutes the adjusting assembly for moving the movable plate 3 up and down. When the movable frame 4 is to be moved up, the fixed rod 6 is rotated to move the screw rod 12 up, thereby moving the fixed rod 6 up, which in turn moves the movable plate 3 up, and the movable frame 4 is moved up by the movable plate 3, so that the movable frame 4 exceeds the cover plate 5 and the groove body 1 to separate the newly formed estuary wetland. The screw rod 12 can be fixed in the threaded hole by the threaded cooperation between the screw rod 12 and the fixed plate 2, so as to fix the height of the movable frame 4 after being moved up, and prevent the movable frame 4 from falling after being moved up.

The top end of the support column 8 is fixed to the bottom surface of the cover plate 5, and the bottom end of the support column 8 is fixed to the top surface of the fixed plate 2. The support columns 8 support the cover plate 5, making the top surface of the cover plate 5 flush with the top of the side wall of the tank 1. Furthermore, the third through hole in the movable plate 3 allows the movable plate 3 to move up and down independently. In some embodiments, a fourth through hole can be provided on the fixed plate 2 for the bottom end of the support column 8 to pass through, fixing the bottom end of the support column 8 to the inner bottom of the tank 1, thereby supporting the cover plate 5.
