Rotary sluice gate
First Claim
1. A rotary sluice gate for controlling the flow through a canal sluice wherein it is installed, said gate consisting of a vane wheel, said wheel including a horizontal shaft mounted transversely across the top of the sluice for rotation about its axis, said wheel having at least three radial vanes fixed about said shaft at circumferential positions, said vanes being of a length so as to be partially and sequentially immersible for operating the gate using the hydraulic energy of the canal for rotating said wheel and means for establishing within the sluice different closing surface areas, and said sluice gate including gate locking means for successively maintaining said wheel at positions where at least two of said vanes are fixedly immersed in the canal sluice.

Abstract
A sluice gate is provided in the form of a vane wheel on a horizontal shaft mounted transversally across the sluice in which it is installed, said vanes being distributed about the shaft and being partially immersible for the purpose of gate operation, same said vanes providing different sluice closing surface areas and said sluice gate comprising wheel locking means to maintain the vanes fixedly in the sluice. Application in small irrigation sluices is suggested.
