Abstract
Single-door flap gates and double-door flap gates are disclosed. A first flap gate includes a first door coupled with a first hinge, a second door coupled with a second hinge, wherein the first door and the second door together form a continuous concave surface, wherein the first hinge and the second hinge couple with a wall, and wherein, when in a closed position, the first door and the second door rest against the wall to cover an opening thereof. The opening may correspond to an end of a pipe that extends away from the first door and the second door. Further, the continuous concave surface may include a radius of curvature configured to be substantially similar to a radius of curvature of the wall, wherein the wall may be interior wall of a cylindrical structure.
Claims19
A flap gate comprising:
- a first door coupled with a first hinge;
- a second door coupled with a second hinge, wherein the first door and the second door together form a continuous concave surface,
- wherein the first hinge and the second hinge couple with an interior wall of a cylindrical structure,
- wherein, when in a closed position, the first door and the second door rest against the interior wall to cover an opening thereof, and wherein the continuous concave surface has a radius of curvature configured to be substantially similar to a radius of curvature of the interior wall of the cylindrical structure thereby enabling the first door and the second door, when in the closed position, to couple with the interior wall, wherein the doors and the hinges are circumscribed by the interior wall of the cylindrical structure.
A flap gate comprising:
- a door that includes a concave surface;
- a hinge coupled to an interior wall, the interior wall of a cylindrical structure having an opening, wherein the hinge is further coupled with the door such that the door opens by rotating about an axis of rotation of the hinge, wherein the door rests against the wall to at least partially cover the opening,
- wherein, when in a closed position, the door rests against the interior wall to cover the opening, and wherein the concave surface has a radius of curvature configured to be substantially similar to a radius of curvature of the interior wall of the cylindrical structure thereby enabling the door, when in the closed position, to couple with the interior wall, and wherein the door and the hinge are circumscribed by the interior wall of the cylindrical structure.
A flap gate comprising:
- a first door coupled with a first hinge;
- and
- a second door coupled with a second hinge, wherein, when in a closed position, the first door and the second door meet to form a continuous concave surface,
- wherein the first hinge and the second hinge couple to an interior of a wall such that the first door and the second door rest against a surface surrounding the opening thereby covering the opening when in the closed position, and
- wherein the continuous concave surface has a radius of curvature configured to be substantially similar to a radius of curvature of the interior of the wall thereby enabling the first door and the second door, when in the closed position, to couple with the interior of the wall, wherein the doors and the hinges are circumscribed by the interior of the wall.
