Description
Technical field
The present invention relates to technical field of wind power generation, a kind of construction party of offshore wind generating partial installation is referred in particular to
Method.
Background technology
China's oceanic area is vast, and offshore wind energy resource enriches, very big using the potential of sea wind wind-power electricity generation, but China
Wind energy on the sea exploitation it is later, since the completion of Donghai Bridge marine wind electric field indicate China formally Oversea wind power generation.
Offshore wind farm is as a kind of novel energy, and country's addressing is open sea environment of the offshore more than 10 nautical miles, mesh at present
Preceding offshore wind turbine installation mainly has two ways, and one kind is directly to carry out integral hoisting using large-scale floating crane,
Two be to use the special large scale equipment of assembling.Because sea situation is severe, especially natural conditions pair such as construction area wind, wave, stream
The influence of ship machine construction, no matter using which kind of above-mentioned scheme, all has the following disadvantages：Due to the overall marine transportation of wind-driven generator
Center of gravity is high, and the risk that causes to tumble is big；And in transport, the ability of transport and hanging device is not only increased substantially, also
Integral installation buffer unit is considered in wind generator design to reduce the clashing and breaking rate of sea-freight and sea dress, is thus caused marine big
The installation difficulty of type wind-driven generator is big.
In order to overcome above mentioned problem, Chinese invention patent (CN101985917A) discloses a kind of offshore wind turbine
Partial installation construction method, tower crane is assembled on land, is refuted using the crane barge side of being hung to, then tower crane installation is existed by crane barge
On pier after and be fixed on pier；Tower crane is on pier after installation, and order installs three section towers of blower fan, lifting
Blower fan main frame, wheel hub and blade；The tower of blower fan is unclamped using cohesion device, upright position is turned to, arm support and king-post is withdrawn,
Tower crane is lifted on transport barge with crane barge.Above-mentioned offshore wind turbine partial installation construction method, although reduce
Deadweight, reduces cost, facilitates the integral installation of tower crane, but is due to the required precision height of assembling, causes to lifting
The requirement of equipment is also very high, still deposits the problem of easily being influenceed to cause reduction efficiency of construction by wave when mounted.
The content of the invention
Therefore, the technical problems to be solved by the invention are to overcome Wind turbines installation in the prior art easily by sea situation shadow
Ring, the problem of causing low construction efficiency is influenceed small so as to provide one kind by sea situation, ensure that Wind turbines are installed to the full extent steady
The qualitatively construction method of offshore wind generating partial installation.
