s1: firstly, a wind driven generator (5) is inserted into a movable pipe (9), at the moment, the wind driven generator (5) pushes a support plate (14) to move, meanwhile, the support plate (14) pushes a threaded ring (15) to move, the threaded ring (15) guides a threaded column (17) to rotate through threads, and at the moment, along with the rotation of the threaded column (17), the threaded column (17) drives a gear (18) to rotate;

s2: the gear (18) guides the rack (19) to move along with the rotation of the gear (18), and at the moment, the rack (19) drives the extension rod (20) to be connected with the positioning hole along with the movement of the rack (19);

s3: along with the descending of the supporting plate (14), the supporting plate (14) pushes the telescopic pipe (11) to rotate through the elastic rubber rod (13), meanwhile, the telescopic pipe (11) pushes the pushing plate (12) to move, along with the movement of the pushing plate (12), the pushing plate (12) pushes the sliding plate (7) to move, and the sliding plate (7) guides the clamping plate (8) to move and clamps the wind driven generator (5);

s4: after the wind driven generator (5) is assembled, the driving belt (24) driven by the motor (3) rotates, meanwhile, the driving belt (24) cancels the pulling force on the pulling belt (25) through the rotating column (23), the gravity of the limiting plate (26) moves, the water inlet is opened at the moment, seawater is guided into the shell (1), and the whole device floats on the sea surface.
