Problems solved by technology

However, the cost of the tooling tower 101 pre-built on the wharf ground is high, which greatly increases the installation cost of the wind turbine. The overall installation process becomes complicated, the work efficiency is low, and the lifting performance requirements for the main crane are also increased

Embodiment Construction

[0022] A method for assembling an offshore wind turbine wharf, such as figure 2 and image 3 As shown, the steps include: (1) the transport ship 1 stops firmly on the water surface on the shore of the wharf, and the main crane 2 is parked on the ground at the extension line of the center line of the transport ship 1; (2) the main crane 2 moves the lower section The tower tube 9 is hoisted and transported to the wind turbine assembly station 3 of the transport ship 1, and the lower tower tube 9 is fastened to the wind turbine assembly station 3; (3) the main crane 2 lifts the upper hanger 4 and Transport to the wind turbine assembly station 3, fasten the upper hanger 4 on the outer wall of the lower tower 9; (4) the main crane 2 lifts the middle tower 10 and transports it to the wind turbine assembly station 3, Fasten the middle tower tube 10 to the top of the lower tower tube 9; (5) the main crane 2 lifts the balance beam 5 and transports it to the wind turbine assembly stat...

Abstract

The invention provides a method for assembling a whole offshore wind turbine at a wharf. In the process of assembling a wind turbine, a main crane is placed on the ground at a extension line of the center line of a transport ship,when impellersare hoisted in accordance with specific conditions (that is,a high slack tide or a low slack tide period) and a certain rotation angle of an engine room, interference between a lifting arm of the main crane and the impellers during hoisting can be effectively avoided, and the bad influence of offshore waves generated during impeller hoisting can be effectively avoided,after the impellersare installed, the impellersare rotated to an inverted Y-shaped state, the interference between the impellers and the lifting arm of the main crane can be further avoided, and the center of gravity of the whole wind turbine can be made to relatively lower at the same time, the fact thatthe interference between a lifting hook and blades of the impellersis not generatedwhen the whole machine is hoisted in an installation position of the offshore wind turbine is met, and collision between the main crane and the blades when the main crane holds upa mast during assembling the impellers on an adjacent station can be further avoided.

Description

technical field [0001] The invention relates to a method for assembling an offshore wind turbine at a wharf. Background technique [0002] Wind power generation is the fastest growing green energy technology in the world. While the construction of land wind farms is developing rapidly, people have noticed some restrictions on the use of land wind energy, such as large area and noise pollution. Given the wind energy resources available and the viability of today's technology, the ocean becomes a rapidly growing wind power market. [0003] At present, there are two mainstream ways to install offshore wind turbines: integral hoisting and split hoisting. For the integral hoisting method, that is, after the wind turbine is assembled as a whole at the wharf, the complete wind turbine is transported to the offshore installation location by a transport ship for offshore installation. The existing integral hoisting method needs to pre-build the tooling tower 101 on the wharf ground...
