Embodiment 1

[0053] This embodiment mainly introduces the overall structure of the mooring system. Such as figure 1 and figure 2 as shown, figure 1 It is one of the structural diagrams of the mooring system of the embodiment of the present invention, figure 2 It is the second structural diagram of the mooring system of the embodiment of the present invention. in, figure 1 Only the overall structure of the mooring system is shown, figure 2 It shows the structure of the whole wind generating set including the wind generating set (hereinafter referred to as the fan 9 ) and the mooring system. The floating wind turbine mooring system of the embodiment of the present invention includes a rigid weight 1 and a floating foundation 2, the floating foundation 2 is provided with a plurality of first cable fixing parts 21, and the rigid weight 1 is provided with a plurality of second cables The fixing part 11 and the plurality of third cable fixing parts 12, the plurality of first cable fixin...

Embodiment 2

[0070] Since the system of the embodiment of the present invention belongs to the constrained mooring system, it has a significant restraint effect on the in-plane and out-of-plane motion of the floating fan 9. Therefore, the motion performance of the floating foundation 2 itself is not high, and the corresponding structural main The scale can be appropriately reduced, reducing the structural weight of the floating foundation 2 and reducing the structural cost.

[0071] Optionally, in order to set the first cable 3 into an adjustable structure, correspondingly, the first cable fixing part 21 may include a hoist, a cable pulley and a chain stopper (not shown in the figure) arranged on the floating foundation 2 ), the fairlead pulley can be arranged on the end column 22 (specifically, it can be arranged on the lower end or the side wall of the end column 22), the winch can be arranged on the end column 22, or can be arranged on the working platform of the floating foundation , t...

Embodiment 3

[0078] This embodiment mainly illustrates an optional structure of the rigid weight 1 . Such as figure 1 and figure 2 The rigid weight 1 can be set as a Y-shaped structure as a whole, and the three sides of the rigid weight have the same structure, and the angle between the three sides is 120 degrees. When the first cable 3 is tensioned and the floating foundation 2 and the rigid weight 1 is in a horizontal state, the center of the rigid weight 1 is located on the central axis of the floating foundation 2. Further, the above-mentioned Y-shaped structure has three sides with equal lengths extending in three directions, the second cable 4 fixed part is located at the end of the upper surface of the three sides of the Y-shaped rigid weight 1, and the third cable is fixed The portion 12 is located at the end of the lower surface of the three sides of the rigid weight 1 . In addition, the end points of the three sides of the Y-shaped rigid weight 1 can just correspond to the th...

Abstract

The invention provides a floating type draught fan mooring system, an offshore wind generator unit and an assembly method of the offshore wind generator unit. The floating type draught fan mooring system comprises a rigid weight and a floating foundation. Multiple first cable fixing portions are arranged on the floating foundation. The rigid weight is provided with multiple second cable fixing portions and multiple third cable fixing portions. The first cable fixing portions and the second cable fixing portions are correspondingly connected through first cables. The third cable fixing portions are connected with fourth cable fixing portions under the sea through second cables. According to the floating type draught fan mooring system, the offshore wind generator unit and the assembly method of the offshore wind generator unit, the structure that the rigid weight is connected to the position below the floating foundation through the cables is adopted, the rigid weight can evenly bear the stress of the cable fixing portions, and therefore the floating foundation can be kept stable in a storm; the rigid heavy block is arranged below the floating foundation at a certain distance, so that the center of gravity of the whole mooring system is lowered, and the overall anti-storm capacity can be greatly improved.

Description

technical field [0001] The invention relates to a floating wind turbine mooring system, an offshore wind power generating set and an installation method thereof, and belongs to the technical field of wind power generation. Background technique [0002] In the deep sea area above 50 meters, there are more and better wind resources that can be developed and utilized, and the market prospect is also broader. To develop deep-sea wind farms in these sea areas, it will not be advantageous to fix the various through-pile structures on the seabed that are commonly used in offshore wind farms, because as the water depth increases, the cost of fixed foundations rises linearly, and fixed offshore wind turbines The cost of construction and operation and maintenance is higher than that of floating type. Therefore, in order to enable the construction of offshore wind farms to develop into deep sea areas, it is necessary to develop economical and practical floating wind turbines. At prese...
