Problems solved by technology

[0003] The biggest difference between offshore wind power generation and onshore wind power generation lies in the location of the two. Since the foundation of the offshore wind power generation unit is at sea, the installation of the offshore wind power generation unit will be affected by the wind, waves and currents at sea. The difficulty of fan installation
At present, the hoisting of domestic offshore wind turbines generally adopts split installation and integral installation technology, but because split installation has many procedures, is greatly affected by the weather, and has low efficiency, it is seldom used.
The integral installation requires a large wharf for pre-assembly, and the transportation of large equipment is also restricted by the weather

Abstract

The invention discloses a rabbit ear type assembling and mounting process for offshore wind driven generation units, which includes the following steps of firstly, assembling a cabin, a hub, a first blade and a second blade to form a rabbit ear type cabin; secondly, conveying the rabbit ear type cabin and a third blade to a mounting location through a transport ship; thirdly, hoisting a tower to the mounting location by a main crane on the transport ship; fourthly, hosting the rabbit ear type cabin assembled in the first step to the top of the tower; and finally, hoisting the third blade to the hub through the main crane. The rabbit ear type assembling and mounting process for the offshore wind driven generation units solves problems that existing offshore wind driven generation units are low in mounting efficiency and easy to be affected by wind wave and current, so that offshore construction efficiency is increased greatly and construction cost is reduced.

Description

technical field [0001] The invention relates to the installation engineering of the offshore wind power industry, in particular to the rabbit-ear assembly and installation process of the offshore wind power unit. Background technique [0002] The intertidal zone is the area between the high and low tide levels of the spring tide, which is submerged and exposed as the tide rises and falls. According to preliminary estimates, the annual average wind speed in the intertidal zone can reach 6-7 m / s, so there is available wind energy in the intertidal zone. For intertidal wind power projects, it mainly involves the construction of wind turbine foundations. [0003] The biggest difference between offshore wind power generation and onshore wind power generation lies in the location of the two. Since the foundation of the offshore wind power generation unit is at sea, the installation of the offshore wind power generation unit will be affected by the wind, waves and currents at sea....
