Water separation gate

A water separation gate is characterized by mainly consisting of a back plate, a gate plate and an opening and closing driving mechanism. The back plate is provided with a discharge opening, the gate plate is relatively slidably connected with the back plate and has an opening work position and a closing work position, a sealing strip is fixedly arranged on an inner lateral surface of the gate plate facing towards the back plate, action parts are arranged on the outer side of the gate plate at intervals and are fixedly connected with the back plate relatively, one of each action part and the gate plate is provided with an abutting portion while the other one is provided with an oblique surface relatively, the gate plate moves to the closing work position from the opening work position under gravity, the abutting portion slides on the oblique surface to generate push force to the side of the back plate, and then the gate plate is driven to contact with the back plate via sealing strips so as to realize watertight seal.. The water separation gate utilizes a slidably opening and closing form, leads the gate plate to press towards the side of the back plate on a gate plate closing station by aid of engagement action of the oblique surface and the abutting portion, achieves seal locking effect, guarantees water stopping sealing property of the gate, and is simple in integral structure and low in cost.
