In step 2, when positioning, which is finished, to be needed to be navigated by water, the connection between propeller and power station is disconnected, cylinder action causes
Suspension hook drives propeller to be flipped up.
It is provided with what is be in contact with propeller on a kind of offshore wind farm construction technology of the present invention, the hull side wall of the hull
Positioning anti-collision block, so as to be positioned when propeller works to its operating position.
Compared with prior art, the beneficial effects of the invention are as follows:
The present invention passes through reasonable arrangement construction procedure so that whole construction technology linking is compact, and the division of labor is clear and definite, greatly improves
Efficiency of construction;Meanwhile, draw, occur during preventing piling bar vertical unexpected to sliding trailer installation hoist engine;And lead to
Cross the setting of dynamic positioning system so that it is convenient that it is positioned, and is easy to carry out positioning construction at any time.
