WAVE ENERGY CONVERSION SYSTEM Russian patent published in 2015 - IPC F03B13/18 F04B9/02 

FIELD: power industry.

SUBSTANCE: group of inventions relates to wave energy conversion, namely to a device for energy extraction from wave motion. Apparatus (10) includes floating actuating mechanism (14) and pump (15) arranged in water column, usually at sea bottom (13). Apparatus (10) operates in a closed loop mode. A fluid medium under high pressure is pumped to the shore by means of pump (15); energy is extracted in the form of useful work by means of plant (17) located on the shore. Mechanism (14) is connected to pump (15) by means of wireline (19) and is in a suspended state in water column (11) above pump (15). Mechanism (14) is provided with a connection device providing an elastic connection between a hollow body and wireline (19). The connection device includes a damping device having a possibility of supporting a rigid connection between the hollow body and wireline (19) till the load between them exceeds the pre-set value; after that, the damping device allows their restricted relative movement in order to weaken the load.

EFFECT: group of inventions is aimed at weakening of excess loads on components of apparatus (10) in order to avoid damage to them under unfavourable weather conditions.
