[0002] Offshore wind power, also known as offshore wind power generation, is a new direction for clean energy in the future. Due to the decreasing economically exploitable wind resources on land, the global wind farm construction has shown a trend of developing from land to offshore. Compared with land-based wind power, offshore wind power resources have high energy efficiency and also have the advantages of not occupying land, high wind speed, less sand and dust, large power, stable operation and zero dust emission. The function of the tower is to fix the wind turbine. The tower is usually composed of multiple towers connected in sequence. The adjacent towers are connected by flanges, and the adjacent flanges are fixed by multiple bolts and nuts.

The movable setting here refers to the movable rod 6 It can slide and rotate, and the movable rod 6 is in a vertical direction and moves in the vertical direction. The free end of the movable rod 6 is provided with a hexagonal sleeve 7, which is fixedly connected to the movable rod 6 and forms a step-like structure. The hexagonal sleeve 7 and the hexagonal bolt 3 or the hexagonal nut 4 are plugged in and matched. In this embodiment, in order to facilitate operation, the hexagonal sleeve 7 is a magnetic type, that is, when the hexagonal sleeve 7 and the hexagonal bolt 3 or the hexagonal nut 4 are plugged in, their positions remain unchanged under no external force.

Since the multiple fixed gears 11 are all engaged with the inner gear ring 904, the multiple fixed gears 11 rotate synchronously, thereby realizing the synchronous forward rotation of multiple rotating plates 801.

[0039] With reference to the above, in the initial state, the two limit blocks 15 on the same slide bar 14 are away from each other, and the slide bar 14 is away from the notch 12. During installation, the notches 12 on the two ring plates 5 correspond one to one, driving multiple slide bars 14 to slide synchronously in the horizontal direction to the axis close to the ring plate 5 until the slide bar 14 is inserted into the notch 12, and then driving multiple forward and reverse screw rods 16 to rotate synchronously forward, and the two limit blocks 15 on the same slide bar 14 slide synchronously in the opposite direction to approach each other until the two limit blocks 15 respectively contact and overlap with the opposite sides of the two ring plates 5, thereby realizing the connection and fixation of the two ring plates 5, that is, locking the two ring plates 5 and keeping their positions unchanged, which not only makes operation more convenient, but also further improves the stability of use.
