ABSTRACT:
The arrangement is of the kind in which at least one water turbine (11) is located in the path of a water source for power generation, comprising a barrage structure (10) which extends across and above the level of the water source (12). The invention is characterized in that the structure is of a cross-sectional width sufficient to absorb static and dynamic loading from said water source and defines only a draught tube (15) for the turbine, in that the turbine is mounted within an inlet casing (19) to form a separate assembly, in that the outlet end of said inlet casing is adapted to be releasably connected to the inlet end of said draught tube, in that locating and locking means (24, 25) are provided for effecting said releasable connection, and in that means (20 to 22) are provided for supporting the weight of the turbine/inlet casing assembly when connected to the draught tube. Preferably, the support means for the turbine comprises a support pier (20) extending upwardly from the wall of the inlet casing to beneath the turbine, and this assembly is, in turn, supported by further support means, comprising a foundation pad (21) mounted on (22) whereby the turbine in use will transmit static and dynamic loading to said piling via said support structure.
