Patent ID: 8177477

Claim:
A dam-free hydraulic power plant comprising: a water passage made in a convergent-divergent shape including a cylindrical neck; a fast-response shutter mounted in the neck; four cross-flow branch pipes, each said branch pipe is connected with the cylindrical neck, the branch pipes each includes a reverse valve of a double-acting type capable of triggering, depending on the water stream direction in the passage, the reverse valves each is mounted within the corresponding branch pipe, wherein a first branch pipe and a second branch pipe are located in front of the shutter, and a third branch pipe and a fourth branch pipe are located behind thereof in relation to the course of water stream in the passage; a first buffer accumulating higher pressure liquid and a second buffer accumulating lower pressure liquid, the first and second buffers are communicated by means of a cross-flow pipeline; a turbine joined with an electro-generator, said turbine is enclosed within the cross-flow pipeline; wherein the first buffer is communicated with the cylindrical neck via the first branch pipe and via the third branch pipe, whereas the second buffer is communicated with the cylindrical neck via the second branch pipe and via the fourth branch pipe.
