<p>[Object of the Invention] An object of the present invention is to provide a water turbine power generator comprising a power generation mechanism provided with a water turbine unit and a power generator unit, and a locking mechanism for engaging the power generation mechanism with a support member, which is free from various drawbacks such as increase in size of the locking mechanism, difficulty of detaching the locking mechanism from a damming board forming the support member when the water turbine power generator is serviced, and so forth. [Disclosure of the Invention] A water turbine power generator comprises a power generation mechanism and a locking mechanism for engaging the power generation mechanism with a support member, wherein the power generation mechanism comprises a water turbine unit and a power generator unit, wherein the water turbine unit comprises a vertically extending cylindrical casing provided with a water inlet port at an upper part of a circumferential side wall and a water outlet port at a lower end, and impellers installed in the cylindrical casing, and wherein the locking mechanism engages the cylindrical casing of the water turbine unit with a damming board which is installed in a canal to form a support member, and wherein the water turbine unit is provided with a pair of impellers disposed coaxially in the cylindrical casing with blades of one of the pair of impellers and blades of the other of the pair of impellers twisted in opposite directions relative to the extending direction of the central axis of the impellers, the power generator unit comprises an inner/outer double rotational armatures-type power generator, and wherein one of the pair of impellers is connected to one of the inner/outer rotational armatures of the power generator unit and the other of the pair of impellers is connected to the other of the inner/outer rotational armatures of the power generator unit, and the locking mechanism engages the power generation mechanism with the support member without fixing the power generation mechanism to the support member.</p> |
