RIVER HYDROPOWER PLANT Russian patent published in 2016 - IPC E02B9/00 E02B9/06 

FIELD: hydropower.

SUBSTANCE: invention relates to hydraulic power engineering and specifically to hydroelectric power plants. Proposed technical solution for hydro-electric power station installed at small and medium rivers is characterised by that the installed on them active hydraulic turbines are used to generate energy due to dynamic head. Creation of velocity head is made by narrowing of riverbed using soil bridge in the form of truncated cone 1. To prevent a wash the new river shores and bottom are reinforced within the range of truncated cone. At the outlet of truncated cone water intake 2 is made also having truncated cone shape. Water intake is connected to turbine pipeline 3 connected with taps 4 to nozzles of ladle hydraulic turbine. At the intersection of rivers with automobile or railway roads, when pipes are installed instead of bridges for passage of river water flow, which also results in bed narrowing, enhancement of water flow rate and concentration of kinetic energy to the outlet holes, the water intake in the form of truncated cone is mounted and connected to the turbine pipeline connected to outlets of nozzles of ladle turbine. In case of short-term increase of water level in river as a result of shower, flood, reduced load, emergency excessive consumption of water is drained into river bed bypassing the water intake. Throughout the length of river at some distance may be installed several hydro-electric power stations (cascade) with automatic remote control from single control panel. Such hydro-electric power stations can be connected to a network or operate under autonomous mode.

EFFECT: high rate of water flow as a result of concentration provides year-round operation of small hydro-electric power stations.
