The improved rope power take-off system used in the wave energy converter of heaving point absorber types

摘要

It is used in a wave energy converter (WEC) of a heaving point absorber type, and the air compressed in the inner space of the buoy substructure due to the upward and downward movement of the buoy 100 in the WEC. It is installed with a power take-off device (air PTO) that calculates electrical power using behavior. In addition, the rope 101 and the drum 200 are disposed on both sides of the center, respectively ① power spring (215) / drum brake (206) / ① friction clutch (600) / ① flywheel (401) / No. ② friction clutch (600-1)/ No. ② power spring (215-1)/ ratchet device (223)/sensor (224)/ No. 3 friction clutch (600-2)/ No. ② flywheel (401-1)/ It includes a transmission (204) / PMSG (205), And the unwinding and rewinding operation of the rope (101) from the outer surface of the drum (200) in the heaving behavior of the buoy (100) by releasing the restraint against the buoy (100) at the incident wave Disclosed is an improved power take-off device (rope PTO) that operates continuously and simultaneously produces electrical power having a high value through efficient and complex operation between self-constructed devices associated with the.
