Example 2:

on the basis of the embodiment 1, the hydraulic pump 5 is arranged at the bottom of the river channel 7 and is connected with a hydraulic control system, and the hydraulic control system is in signal connection with the electric cabinet.

Example 3:

on the basis of the embodiment 1-2, the rubber sleeves 4 are wrapped at the two end parts of the interception dam 3, and the rubber pads 6 matched with the rubber sleeves 4 at the end parts of the interception dam 3 are arranged on the river banks 1 on the two sides of the river channel 7. The two ends of the interception dam 3 are wrapped by the rubber sleeves 4, and the rubber pads 6 are arranged on the river levee 1, so that water leakage can be avoided, and the effect of intercepting and storing water is improved.

Example 4:

on the basis of embodiments 1 to 3, the position of the rubber pad 6 on the wall of the river bank 1 corresponds to the movable position of the interception dam 3. By the structure, when the interception dam 3 rotates, the rubber sleeve 4 at the end part of the interception dam 3 can be in contact with and sealed with the rubber pad 6 on the wall of the river bank 1, water cannot leak from the wall of the river bank 1 of the interception dam 3, and the effect of intercepting and storing water is improved.
