Abstract
A fluid flow control and debris intercepting apparatus for controlling the flow of fluid and the introduction of debris into the entrance of a water diversion system such as a curbside storm drain.
Claims14
A fluid flow control and debris intercepting apparatus for controlling flow through a structure having an opening defining a fluid flow channel comprising:
- (a) first and second side panels connected to the structure;
- (b) a support member connected to said first and second side panels and spanning the opening defining the fluid flow channel;
- (c) a plurality of transversely spaced apart flow control vanes carried by said support member for controlling fluid flow through the fluid flow channel, each of said flow control vanes having an upper portion, a lower portion and an intermediate portion and being movable between a first position and a second position permitting an increase in the volume of fluid flow through the fluid flow channel;
- (d) a yieldably deformable biasing member comprising an elongated cable connected to each of said flow control vanes proximate the intermediate portions thereof for resisting movement of each of said flow control vanes toward said second position;
- and
- (e) a tensioning mechanism carried by one of said first and second side panels for controlling the tension in said elongated cable, said tensioning mechanism comprising a spring operable associated with said elongated cable.

- a hollow cylindrical member connected to said connector plate and extending there from, said hollow cylindrical member including a driving member;
- a cable spool circumscribing said hollow cylindrical member and connected to said cable;
- a helical torsion spring circumscribing said hollow cylindrical member and connected to said cable spool;
- and a tensioning assembly connected to said torsion spring for twisting said torsion spring, said tensioning assembly, including a driven member operably associated with said driving member;
- and
- (f) an operating assembly operably associated with said driven member of said tensioning assembly for controllably rotating said driven member.
