10. A conveniently controlled offshore wind turbine installation and connection method, using the conveniently controlled offshore wind turbine installation and connection device according to claim 9, characterized in that: The following steps are involved: S1. First, the lifting plate (20) is connected to the lifting rope, so that the lifting connection structure (1), the side guard frame (2), the supporting frame (3), the fitting support plate (4), and the reinforcement base (5) can be lifted, and the fan blades can be fastened by multiple sets of connecting devices, thereby ensuring the stability of the lifting; S2. Before use, the fan blade is inserted between the first contact wheel (27) and the arc-shaped guide frame (34), and at this time, the fan blade is in contact with the fitting support plate (4), and the side guard frame (2), the supporting base frame (3), the fitting support plate (4), and the reinforcement base (5) are fixedly integrated to perform uniform load-bearing work. Then, the hydraulic controller (31) is controlled to pull back, driving the hydraulic telescopic control guide rod (32) to move upward, so that the reinforcement end frame (33), the arc-shaped guide frame (34), the buffer platform (35), and the second contact wheel (36) change their positions. At this time, the second contact wheel (36) is in contact with the fan blade to perform cooperative load-bearing work, thereby performing a position limiting work on the fan blade; S3, then, the first limiting mechanism (8) operates, the upper end of the electric-controlled hydraulic control rod (16) in the first limiting mechanism (8) is hingedly arranged with the second matching guide rod (17), and the lower end of the electric-controlled hydraulic control rod (16) is hingedly matched with the first matching guide rod (15). At this time, the electric-controlled hydraulic control rod (16) extends, and drives the movable adjustment frame (13) to move through the electric-controlled hydraulic control rod (16). At this time, the movable adjustment frame (13) rotates around the supporting matching rod (12), and synchronously drives the contact extrusion wheel (14) to move around the supporting matching rod (12). The supporting matching rod (12) contacts the fan blade and is limited and fixed again, thereby improving the connection stability. The first contact wheel (27) moves through the second electric-controlled hydraulic control rod, driving the first contact wheel (27) to move downward, so that the first contact wheel (27) contacts the upper surface of the fan blade, thereby ensuring the stability of the fan blade when hoisting; S4. Finally, the fan blades can be hoisted by a crane. The center of the support and stabilization plate (22) is connected to the platform frame (25) through a fixed cushion block (28) and a hydraulic buffer seat (29), which can improve the buffer protection performance of the center position. The support and stabilization plate (22) is fixed by a positioning shaft seat (21), an inclined rod frame (23) and a matching docking shaft (24) to fix the four corners of the platform frame (25), thereby improving the structural stability of the platform frame (25). The hydraulic buffer seat (29) is used to absorb excess stress, which can reduce the problem of high-altitude shaking, thereby enabling stable lifting.
