Problems solved by technology

Compared with segmented installation, the integral installation method simplifies the offshore installation process and reduces the difficulty of installation, but due to the large overall structure of the offshore wind turbine, there are great difficulties in the process of hauling at sea, so the integral installation method is currently still no practical application

Embodiment approach

[0041] Embodiments of the present invention include the following steps:

[0042] (1) Offshore wind turbines are hoisted horizontally. Firstly, the whole device is docked at the port wharf, the rotating column 1 is rotated to a horizontal position, and the supporting device 5 is stretched horizontally to ensure the force balance and horizontal position of the rotating column, and the offshore wind turbine 7 is hoisted horizontally from the shore and placed on the self by using large hoisting equipment. On the lock device 3, the rotating lock frame 12 is affected by the pressure of the offshore wind turbine 4, and the shaft connection 14 is gradually closed from the open state, and the offshore wind turbine 4 is fastened to the rotating column 1 through the cooperation of the rotating lock frame 12 and the fixed lock frame 11 , to ensure the horizontal position and stability of the offshore wind turbine.

[0043] (2) Horizontal hauling. The offshore wind turbine 4 is fixed on...

Abstract

The invention discloses an integrated mounting ship capable of achieving offshore wind turbine horizontal towage. The ship comprises a horizontal towage system and a vertical mounting system. The horizontal towage system and the vertical mounting system take an H-shaped ship body and a rotating stand column as the basis, specifically, the horizontal towage system comprises a self-locking device and a horizontal supporting device, and the vertical mounting system comprises a rotating device, a telescopic device and a vertical positioning device. The offshore wind turbine integrated transport and mounting problems can be solved, free conversion of offshore wind turbine horizontal transport and vertical mounting can be achieved, the construction difficulty is reduced, and the construction period can be shortened.

Description

technical field [0001] The invention relates to an integrated installation ship for horizontal hauling of offshore wind turbines, in particular to an integrated transportation installation ship capable of realizing free conversion between overall horizontal haulage and vertical installation of offshore wind turbines. Background technique [0002] At present, the installation of offshore wind turbines in my country mainly includes two forms: segmented installation and integral installation. [0003] Segmented installation means that the offshore wind turbines are first transported to the designated installation location in sections, and then the wind turbines are assembled and installed offshore by professional installation equipment. The difficulty is that the segmented installation requires high precision of the offshore operation equipment during the construction process, the construction is difficult and the operation time is long. [0004] Integral installation means th...
