When the sealing plate completely covers the drain opening, the sealing effect of the contact portion can be increased by the presence of the rubber plate.

Preferably, in order to restrict the stroke of each sealing plate, two sides of each sealing plate are respectively provided with a limiting block, and the limiting blocks and the flashboards are welded and fixed.

The beneficial effects of the utility model are that:

when the required water discharge is larger, the height of the whole gate plate is adjusted by controlling the screw hoist; when the required water discharge is smaller, the opening degrees of the two water outlets are independently adjusted by controlling the speed reducing motor. The rising times of the whole flashboard are reduced through the arrangement of the water outlet, and the service life of the screw hoist is prolonged. The sealing plate is small in size, light in weight, low in power consumption in the operation process, low in requirement on the speed reducing motor, and capable of reducing operation cost and later maintenance cost.
