Abstract
A beaver control device for a culvert pipe features a generally conical screen having a base portion and an apex portion connected by a plurality of rods. The base portion has a rim sized to fit about the end of the culvert pipe. The apex portion has a rim with an opening sized to selectively receive a weeping tile or other drainage pipe. The screen prevents beavers from damming the culvert while allowing the drainage pipe to drain into or pass through the culvert. A pin is provided to either lock the drainage pipe in place or partially close off the opening in the apex portion when not in use. The screen is movable between raised and lowered positions to allow easy access to the screen and culvert. In one embodiment, the screen is constructed in multiple pieces to allow for easy transport and on-site assembly.
Claims13
A combination of a beaver control device, a culvert pipe and a drainage pipe, said combination comprising:
- a generally conical screen having opposite first and second ends, said generally conical screen comprising:
- a base portion at the first end of the generally conical screen, said base portion comprising a first rim sized to receive the end of the culvert pipe in a first opening defined by the first rim;
- an apex portion at the second end of the generally conical screen, said apex portion comprising a second rim sized to selectively receive the drainage pipe in a second opening defined by the second rim;
- a plurality of spaced apart rods extending from the first end to the second end and connecting the base and apex portions at spaced apart positions about the first and second rims;
- and
- a retaining mechanism cooperative with the generally conical screen and operable to effect selective coupling thereof to the drainage pipe to retain the drainage pipe in position to drain into the culvert.
