Hydroelectric power station
First Claim
1. A low-head hydroelectric power station comprising a dam forming an upstream pool and a downstream pool in a watercourse, at least one turbine having a turbine runner located within a high flow-velocity passageway formed at the base of the dam, and at least one electric generator coupled to the turbines and housed within a totally submerged casing, wherein said generator casing is located within the upstream pool at a distance from the dam and the turbine and upstream of the high flow-velocity zone, said casing being provided with an inspection shaft having an opening located above the normal water level and fixed on a flooring structure in a demountable and removable manner.

Abstract
In a low-head hydroelectric power station, a turbine runner is mounted within the hub of a convergent-divergent draft tube at the base of a dam. At least one turbine is coupled to one or more electric generators housed within a casing which is totally submerged within the upstream pool. The distance from the generator casing to the draft tube intake is sufficient to prevent any interference with the water flow. The casing is provided with a vertical access and inspection shaft, the top opening of which is located above the normal water level and removably fixed on a flooring structure.
