The present invention relates to a method for installing a sea wind power generator by using lead rails, and the method includes the steps of: locating a large-sized lower support on sea and close-contacting barges with the both sides of the lower support and fixedly erecting a plurality of fixing posts located at the corners of a deck of each barge on the sea surface, thereby fixing the pair of barges on the sea surface to provide a working area thereon; locating a pair of posts of a tower crane and a cage for each post at the both sides of the lower support, ascending a nacelle assembly and overhead crane, and fixedly coupling an intermediate support to the lower support; and locating the lead rails along the deck of the barges and the front surface of the intermediate support and ascending an upper support along the lead rails by means of the overhead crane. Next, after a nacelle base, a support frame, the lead rails, and the tower crane are disassembled from the located positions, a plurality of propellers connected to rollers located inside a rotary part of the nacelle assembly are lifted by means of a winch and are inserted into a plurality of coupling grooves of the rotary part, and then, the barges are separated from the lower post and moved by using a motor ship. The method of this invention has relatively low installation costs when compared with conventional installing methods and provides more effective and rapid in¬ stallation processes to advantageously reduce the construction period. |
