SEPARABLE ROTOR BLADE FOR GENERATING TIDAL CURRENT POWER

摘要

Provided is a separative tidal current rotor blade including: a hub constituting a body of a rotor; a blade formed by coupling a plurality of blade blocks together; a connecting member for connecting the hub and the blade; and a coupling unit for coupling one end of the connecting member to the hub. The blade can be mass produced and has excellent compactibility by dividing a body unit of the blade into a plurality of blocks and assembling the blocks. Also, manufacturing and maintenance costs and time can be reduced since the body unit of the blade is divided into the blocks. In addition, the blade can be prevented from being damaged since a shock absorbing member is disposed between blade blocks to absorb a sudden shock.
