Embodiment Construction

[0020] Such as figure 1 and figure 2 As shown, this embodiment provides a hoisting method for a wind turbine, wherein the wind turbine includes a tower 11, a nacelle 12 installed on the tower 11, and an impeller 13 installed on the nacelle 12, the The tower 11 is composed of a lower tower 11a, a middle tower 11b interconnected with the lower tower 11a, and an upper tower 11c interconnected with the middle tower 11b. The impeller 13 includes a hub and is installed on the The three blades on the hub, and the hub is installed on the nacelle 12, the hoisting steps are as follows: Step S1: Fix the tower 11 on the transport ship, and install the hub on the ground in the land area After the nacelle 12 is installed, the first blade and the second blade are installed on the hub to form a nacelle impeller set; Step S2: use a hoisting device to install the nacelle impeller set on the top of the tower 11; Step S3: The third blade is mounted on the hub using lifting equipment.

Abstract

The invention relates to a lifting method of a wind turbine generator. After a tower is fixed on a transportation ship, and a hub is mounted on a cabin on the ground of a land area, a first blade and a second blade are mounted on the hub to form a cabin impeller set; then, the cabin impeller set is mounted at the top of the tower by using lifting equipment; and finally, a third blade is mounted on the hub by using the lifting equipment. The lifting method facilitates improvement of the mounting efficiency, reduces the mounting difficulty, and guarantees the whole stability of the wind turbine generator.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a method for hoisting a wind turbine. Background technique [0002] With the rapid development of the wind power industry, the openness of onshore wind farms is becoming increasingly saturated. Offshore wind farms, with their advantages of high wind speed, low turbulence, and small wind shear, have become a field of wind power that urgently needs to be developed. In addition, with the gradual increase of the capacity of a single wind turbine, the volume and weight of each part of the wind turbine are also increasing. For example, the weight of a wind turbine is about 800 tons. Installation to offshore foundations is very difficult. [0003] Because the load environment of offshore wind turbines is relatively complex and has great uncertainty, random nonlinear wind loads and wave loads will pose great challenges to the safety control of offshore wind turbines. At p...
