Offshore wind turbine installation platform and hoisting device thereof

Abstract

The invention discloses a hoisting device of an offshore wind turbine installation platform, comprising a hoisting boom and a derricking wire rope, wherein the root of the hoisting boom is hinged with a platform body of the offshore wind turbine installation platform and the tail end of the hoisting boom is connected with the derricking wire rope fixedly. The hoisting device further comprises a guide frame, wherein a wind turbine holding mechanism is arranged at the tail end of the guide frame and the tail end of the hoisting boom is hinged with the guide frame; a balance arm in parallel with the hoisting boom is arranged at one side of the guide frame, which is far away from the hoisting boom, and the hoisting boom is equal to the balance arm in length; a transverse beam in parallel with the platform body is arranged on the guide frame fixedly, the root of the balance arm is hinged to the platform body and the tail end of the balance arm is hinged to the transverse beam. According to the invention, a wind turbine can be always kept in an upright state without other auxiliary ship drawing, so positioning difficulty of the wind turbine is reduced and even big sea stormy waves cannot affect the installation of the wind turbine much, thus an offshore environment affects the construction less. The invention also discloses the offshore wind turbine installation platform provided with the hoisting device.

Description

technical field [0001] The invention relates to the technical field of fan installation equipment, in particular to a hoisting device for an offshore fan installation platform. The present invention also relates to an offshore wind turbine installation platform comprising the above-mentioned hoisting device. Background technique [0002] With the rapid development of my country's economic construction, electric energy has a greater impact on economic construction and people's lives, and wind power generation, as one of the various power generation methods, has attracted more and more attention. [0003] Wind power generation is the use of wind turbines to convert the kinetic energy of the wind into mechanical energy, and then the generator converts the mechanical energy into electrical energy and transmits it to the grid. Offshore wind energy resources are relatively abundant, so building wind farms offshore has become a general trend in the field of wind power generation. ...

AI Technical Summary

Problems solved by technology

However, due to the strong sea breeze, the boom often shakes when hoisting the wind turbine, which makes the positioning difficult during construction. The positioning accuracy of the installation ship and the foundation of the offshore wind turbine is high. Construction can only be carried out when the sea conditions are good. The construction window period is short, which seriously affects the construction efficiency
