Embodiment Construction

[0022] Such as figure 1 and figure 2 As shown, this embodiment provides a construction method for separate installation of offshore wind turbines. The wind turbines are located on the platform of the wind turbine foundation 10, wherein the wind turbines include towers and are located above the towers. The fan includes the following steps: step S1: sinking the pile foundation of the fan foundation 10; step S2: manufacturing the auxiliary platform 20, and installing the auxiliary platform 20 next to the fan foundation 10, so that the The auxiliary platform 20 is close to the fan foundation 10; step S3: install a spreader on the auxiliary platform 20, and continue to inspect the cable pipes, ship berthing facilities, and anti-collision structures of the fan foundation 10 under the cooperation of the spreader. Install and carry out the construction of cap steel bars, templates and concrete structures; step S4: use the sling on the auxiliary platform 20 to hoist the tower to the ...

Abstract

The invention relates to a construction method applied to split installation of offshore wind power generators. A wind power generator is located on a bearing platform of a fan foundation and comprises a tower frame and a fan located at the upper part of the tower frame. An auxiliary platform is used for lifting the wind power generator on the fan foundation, so that the split installation of the wind power generator is achieved. Through the construction method, the auxiliary platform is used for achieving split installation of the fan; the influence of the wind wave on the installation construction of the fan is effectively reduced; the installation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a construction method for separate installation of offshore wind power generators. Background technique [0002] my country has a vast sea area and abundant offshore wind energy resources. The potential of using sea wind to generate electricity is great. However, the development of offshore wind energy in my country is relatively late. The completion of the Donghai Bridge offshore wind farm marks the official start of offshore wind power generation in my country. [0003] As a new type of energy, offshore wind power is currently selected as an offshore environment that is more than 10 nautical miles offshore. At present, there are two main methods for the installation and construction of offshore wind turbines. One is to use large floating cranes for direct overall hoisting, and the other is to Use fan installation special large-scale equipment. Due to the harsh se...
