SUBMERSIBLE MONOBLOCK MICROHYDRO POWER PLANT Russian patent published in 2014 - IPC F03B13/10 F03B17/06 

FIELD: electricity.

SUBSTANCE: submersible microhydro power plant for electric energy generation includes hydraulic turbine with vertical rotation axis connected to electric generator, also it includes water flow formers and device protecting against floating objects. Lower end of runner shaft 3 is connected directly to generator shaft 17 by means of splined joint. Thrust bearing of runner is rigidly fixed in upper cover of electric generator housing 15 so that it is simultaneously a pilot bearing for electric generator. Electric generator is end-type, water-filled and is located under hydraulic turbine. Hydraulic turbine housing 1 and electric generator housing 15 form single structure monoblock.

EFFECT: reducing dimensions and weight, generating cheaper electric energy due to absence of investments to plants building, simplifying structure and erection works method, reducing maintenance costs.
