Orifice shield for drainage pipe
An orifice shield for distributing water flowing from an orifice in a pipe and preventing blockage of the orifice. The orifice shield includes a housing including a cage, the cage being defined by a first plate joined to a second plate via fins, the fins being joined via a plurality of lateral members, the cage including a plurality of openings or slots defined between the fins and the lateral members, the first plate including a central shaft extending downwardly toward the second plate. A freely rotating fan is mounted on the shaft. The fan is adapted to evenly distribute the water flowing from the orifice via the openings or slots. The housing may also be a box housing including a plurality of openings or slots defined therein. The housing includes a first clamp and a second clamp that are adapted to be removably secured to the pipe.
1. An orifice shield for distributing water flowing from an orifice in a pipe and preventing blockage of the orifice, said orifice shield comprising:
a housing including a cage, said cage being defined by a first plate joined to a second plate via fins, said fins being joined via a plurality of lateral members, said cage including a plurality of openings or slots defined between said fins and said lateral members, said first plate including a central shaft extending downwardly toward said second plate;
a freely rotating fan mounted on said shaft, said fan adapted to evenly distribute the water flowing from the orifice via said openings or slots; and
a first clamp extending from said first plate and a second clamp from said second plate, said first and second clamps adapted to be removably secured to the pipe.
