Chinese patent publication No. CN102099530a proposes a self-closing flood barrier for protecting inland areas against flood water, wherein the flood barrier comprises: a chamber including a first sidewall and a second sidewall; a water inlet for letting in water; a single support block disposed on the first sidewall; and a dam wall member disposed in the chamber so as to be movable up and down. The dam wall portion includes: a retaining wall for preventing water from flowing into an inland region; a force application member for moving the dam wall member upward; and a latching element for providing an obstruction to limit upward movement, the latching element including an angled surface. The support block comprises an inclined surface against which the inclined surface of the blocking element acts in the closed state of the flood protection barrier. Due to the orientation of the angled walls in the support blocks, the blocking element is forced to move sideways and thereby generates a lateral force pushing the dam wall portion to one side of the sluice chamber.

Aiming at the related technology, flood enters the maintenance pit through the water inlet, and floats in the flood enter the maintenance pit along with the water inlet, so that the normal floating work of the flood control barrier is easily influenced if impurities such as floats are not filtered.
