Sluice gate for automatically regulating a level
First Claim
Patent Images
1. A sluice gate for automatically regulating a level of liquid flowing within a channel, the gate comprising:
- means for enabling said gate to oscillate about a transverse oscillation axis;
a plate disposed upstream from said oscillation axis in order to close to a greater or lesser extent said channel between a regulated level reach and another reach, said plate being cylindrical in shape about said axis;
a float operatively connected to said plate and dipping to a greater or lesser extent into said regulated level reach in order to raise or lower said plate as a function of variations in the level of said reach; and
adjustable balancing masses for conferring substantially neutral balance on said gate when the level of said regulated level reach is at a reference value;
wherein said gate further includes an adjustment support system for maintaining, on command, an adjustment mass in one or other of at least two adjustment positions situated at a longitudinal distance apart from each other so as to vary said reference level while retaining the substantially neutral character of said balance.

Abstract
The gate of the present invention regulates the level of a downstream reach (4) by means of a sector-shaped plate (1) carried by a frame (6, 7) that oscillates about a axis (5) and that also carries a float (8) dipping into said reach. Substantially neutral equilibrium is obtained at a reference level by raising the center of gravity above the oscillation axis, and the reference level is adjusted by transferring water between two longitudinally offset tanks (11, 13). The invention is particularly suitable for irrigation networks.
