| titleOfInvention | A flap door device |
| abstract | The invention discloses a flap door device, comprising: an inverted trapezoidal door body, the door body is provided with a hinge, the bottom edge of the door body is provided with a bottom water stop strip, and the side edge of the door body is provided with a side water stop strip; The bottom sill embedded part set at the bottom of the river channel, the bottom sill embedded part has a hinge seat; the lateral embedded part used for the side part of the river bank, the lateral embedded part has a conical surface; the hinge of the door body and the bottom sill embedded part The hinge seat is hinged, and the rotation of the door body realizes the adjustment of the upstream water level of the door body. During the rotation of the door body, the bottom water stop strip of the door body is kept in close contact with the surface of the embedded part of the bottom sill, and the side water stop strip of the door body and The conical surfaces of the lateral embeds maintain a tight fit. The inverted trapezoidal door body provided by this patent is consistent with the inverted trapezoidal channel section, which will not reduce the flow cross section of the river channel, so that the channel water can flow smoothly through the gate; Complete water stop seating surface in a simple form. |
