lines

43, 41, the plurality of connecting

lines

43, 41 being spaced about the axis of the support structure 30, and each connecting

line

43, 41 being connected at one end to the sea floor and at the other end to the bottom buoy 31. Specifically, the arrangement of the connecting

ropes

43 and 41 facilitates fixing the floating offshore wind power relative to the seabed, i.e., it is ensured that the position of the floating offshore wind power is not greatly deviated, and the floating offshore wind power does not drift to other sea areas along with the sea wind. The connecting

ropes

43 and 41 are generally steel ropes, and the outer sides of the steel ropes are coated with corrosion-resistant materials to prolong the service life of the connecting

ropes

One end of the connecting rope 43 and the connecting ring 41 are fixedly connected through the fixing ring, and the other end of the connecting rope 43 and the anchoring ring are fixedly connected through the fixing ring. Wherein, the connecting ring and the anchoring ring can be arranged by adopting a detachable structure so as to replace the connecting rope 43 and the cable 41.

As shown in fig. 1 to 3, in one specific embodiment, the number of the connecting

ropes

43 and 41 is four, and four connecting

ropes

43 and 41 are respectively disposed at four corners of the supporting structure 30. By fixing the four connecting

ropes

ropes

43 and 41, so that the stress is kept stable. Of course, the number of the connecting

cords

43 and 41 may be more, for example, six, eight, etc. It should be noted that the number of connecting

cords

43 and 41 is increased in an even number, which ensures a balanced load of the support structure 30. For example, when the number of the connecting ropes 43 and the number of the ropes 41 are six, four corners of the support structure 30 are distributed, and the remaining two are disposed at two opposite corners of the support structure 30. When eight, two connecting

ropes

43 and 41 are connected at each top corner. In a further embodiment, the area of the quadrilateral enclosed by the connecting lines 43 and the four anchoring rings installed on the seabed is larger than the area of the quadrilateral enclosed by the four connecting rings on the bottom pontoon 31.

The number of the connecting strings 43 is plural, and the plural connecting strings 43 are spaced apart around the axis of the suspension plate 42 to improve the force balance. Wherein the circular diameter of the suspension plate 42 may be the same as the circular diameter of the middle base 321 in the center column 32.

1-3, in some embodiments, the tower 20 is disposed in a tapered configuration from a side of the support structure 30 facing the wind turbine assembly 10. In particular, such an arrangement ensures that the end of the tower 20 connected to the support structure 30 has a larger force-bearing area, thereby ensuring smooth force-bearing and higher support. Meanwhile, as the tower tube 20 extends upwards, the contact area between the tower tube 20 and the wind flow in the air can be reduced by gradually reducing the diameter, and the resistance of the wind flow to the tower tube 20 is reduced, so that the fan unit 10 can be supported more stably. Wherein the axis of the tower 20 coincides with the axis of the center post 32. The fan unit 10 includes a generator 11, a blade 13 and a rotating shaft 12, the generator 11 is connected with the rotating shaft 12, and the blade 13 is installed on the rotating shaft 12. Wind acts on the blades 13, so that the blades 13 drive the rotating shaft 12 to rotate, thereby generating electricity. The number of the blades 13 is plural, and the plural blades 13 are uniformly distributed at intervals around the axis of the rotating shaft 12. Typically, the number of blades 13 is three. Wherein each blade 13 is spirally bent so as to increase a contact area with wind current to sufficiently utilize wind power for power generation.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
