ABSTRACT:
An energy-efficient automatic sluice gate for sustaining a fluid level, separating an upstream pool from a downstream pool in an irrigation system and enabling the level of water in one of the pools to be kept constant at a settable value. A sluice gate separates an upstream pool (1) from a downstream pool (2) and enables the level of one of the pools to be kept constant at a settable value, said gate comprising a baffle (3) movable about a horizontal rotational shaft (4) whereby the rotation of the baffle about its shaft determines the flow of water downstream, said baffle constituting a segment of a cylinder having the said rotational shaft as its axis, and further comprising a box member (7A) and a second box member (7B), both moving with the baffle and dipping respectively in the upstream pool and in the downstream pool, means (9, 13, 15) for at least partially filling the box members, means (20) for keeping constant the level in the first or the second box member according to whether the level in the upstream pool or in the downstream pool is to be kept constant and means (50) of setting said constant level value.
