| Description/Abstract | Small power stations according to the invention consist of at least 3 floats kept at equal distances and parallel to each other by spacer pipes, which contain all the parts of the machines and units. Only the blades for taking up the wave energy are situated between these floats. These blades of long rectangular shape move around horizontal waves, which run near the lower longitudinal edge. By using a modular system of floats and blades, large outputs can be produced. The floats anchored near the coast on the bottom of the sea hold the blades at a suitable height relative to sea level. The periodic waves move the blades to and from through about 90/sup 0/, and transmit the wave energy by shaft bearings and cranks projecting from the ends of the blades into the float to pump pistons. The 4 blades between 3 floats actuate a total of 8 pistons, 2 in each of the side floats and 4 in the central float. Water displaced by these pistons at high pressure runs in a closed circuit through a pressure vessel and a turbine coupled to a generator, and returns to the suction side of the pump not under pressure via a reservoir at the bottom of the float. The system forms a torque converter, which matches an available form of energy to a machine (a fast turbine) working in different conditions. By using the spacer pipes between the floats as suction and pressure pipes of the whole pump system, the plant may be equipped with one large turbine in the central float, instead of one turbine in each float. |
