Wave modular hydroelectric

 

(57) Abstract:

Wave hydroelectric power plant is designed to convert the energy of pitching floating means into electrical energy by alternate movement of fluid through the hydraulic turbine. Hydroelectric has anchored floating vehicle with a suspended modules hydraulic turbines. Each of the modules includes at least two flow part with guide vanes and impellers with opposite rotation, kinematically connected by means of cardan shafts with generators installed in the hull of the floating means. The flowing part of the turbine rigidly interconnected, their suspension is made free through the cables, and the connection with the anchor made by hydropnic circuits, freely lowered to the bottom. Design of hydroelectric power plant can improve its capacity. 2 Il.

The invention relates to wave energy, namely, devices for energy conversion pitching floating means into electrical energy by alternate movement of fluid through the hydraulic turbine.

Known wave hydroelectric containing sakor the at least two flow part with guide vanes and impellers with opposite rotation, kinematically connected by means of cardan shafts with generators installed in the hull of the floating means (U.S. patent 4462211A, IPC 7 F 03 B 13/12, 1984).

This wave has a hydroelectric low energy power.

The objective of the invention is to increase the energy capacity.

This object is achieved due to the fact that the wave modular hydroelectric contains a floating tool with freely suspended modules hydraulic turbines, each of which includes at least two rigidly interconnected flow part with guide vanes, impeller turbines with opposite rotation kinematically connected by means of cardan shafts with generators installed in the hull of the floating means, and hydropenia anchor chain, freely lowered to the bottom.

The invention is illustrated by drawings, where Fig. 1 illustrates schematically the wave modular hydroelectric power station, General view (partially broken-out section); Fig. 2 is a top view in Fig. 1 (partial broken-out section).

Wave modular power plant comprises a floating tool 1, the generator 2, the cables 3 charms proto blades 8, impellers 9 turbines, shafts 10 of impellers, thrust bearings 11, hydropenia anchor chain 12, the armature 13 with aconitase 14.

It is advisable the length of the floating means and the depth of flowing parts of the modules turbines is equal to half the length of the dominant waves in this sea area.

Wave modular hydroelectric works as follows.

Floating tool 1, swaying on the waves entrain suspended thereto modules turbines, forming in their flowing parts of 4 alternating streams of water. While the impellers 9 turbines when interacting with streams of water begin to rotate, and torque through the propeller shaft 5 is transmitted to the generators 2. Produced by the generators 2 electricity can be used in continuous processes carried out directly on the floating tool 1, and may be transmitted by cable to shore.

Wave hydroelectric containing anchored floating vehicle with a suspended modules hydraulic turbines, each of which includes at least two flow part with guide vanes and trigeneration, installed in the hull of the floating means, characterized in that the flow-through part of the turbine rigidly interconnected, their suspension is made free through the cables, and the connection with the anchor made by hydropnic circuits, freely lowered to the bottom.
