Background

Recently, when an offshore wind turbine generator system installs blades, a single-blade hoisting mode is gradually used. The single-blade hoisting refers to a hoisting mode that a single blade is clamped by using a special single-blade clamp and then hoisted to the air to be butted with a variable-pitch bearing. Compared with the traditional three-blade hoisting, the single-blade hoisting has the following two advantages: 1) The operation window time is long, the single-blade hoisting can be operated at the wind speed of 12m/s, and the three-blade hoisting can be operated only at the wind speed of 8m/s, so that the single-blade hoisting is not limited by the wind speed and is not rigorous. 2) The ship deck area that occupies is little, and single blade hoist and mount need not to carry out the impeller on the ship deck and assemble, but the area occupied on the deck that significantly reduces.

With the gradual increase of the single-unit capacity of the offshore wind generating set, the length of the set blades is longer and longer, the assembly and hoisting of the impeller of the offshore large wind generating set cannot be met by an installation ship on the market under the conditions of hoisting weight, hoisting height and limited deck area, and the single-blade hoisting mode becomes the mainstream mode of the offshore large generating set hoisting.

Different blades are required to be customized and designed aiming at different wind speed areas, the length of the blade designed in a low wind speed area is generally longer, the length of the blade designed in a high wind speed area is shorter, the structural design of different blades is different, a single-blade clamp is required to be provided with a corresponding supporting structure, the supporting structure is required to be customized and designed according to the surface bearing load of different blades, the surface shape of the blades, the positions of main beams and webs of the blades, and higher cost is brought to the change of the single-blade clamp.
