Embodiment Construction

[0017] combine Figure 1 to Figure 4 The self-elevating offshore wind turbine installation vessel of the present invention is described. The invention is a steel non-self-propelled self-elevating wind power installation platform, which has the condition of being refitted into a short-distance deployment and sailing. The installation space of the generator set and the propulsion device is reserved in the design, and it is mainly used for the wind power installation in the offshore shallow water area of ​​the Yellow Sea. .

[0018] The self-elevating offshore fan installation ship of the present invention mainly includes a hull 1 provided with a lifting mechanism room and a leg 2 passing through the lifting mechanism room, a friction winch 3 arranged on the hull, a guide pulley 9 and a steel wire rope 10; There are fixed pulleys 4 at the top of the legs and fixed pulleys 7 at the bottom of the legs. The measuring device is used to measure the tension, stroke and speed of the wi...

Abstract

The invention discloses a self-elevating offshore wind turbine installation vessel which comprises a vessel body, spud legs, friction winches, guide pulleys and steel wire ropes, wherein the vessel body is provided with lifting mechanism chambers, the spud legs penetrate the lifting mechanism chambers, and the friction winches, the guide pulleys and the steel wire ropes are arranged on the vessel body. Spud leg top fixed pulley blocks and spud leg lower fixed pulley blocks are arranged on the spud legs, lifting platforms are arranged on the lifting mechanism chambers, platform lower fixed pulley blocks and platform upper fixed pulley blocks are arranged on the lifting platforms, one end of each steel wire rope is fixed at the top of the corresponding lifting mechanism chamber, the other end of each steel wire rope is sequentially wound on the corresponding spud leg top fixed pulley block, the corresponding platform upper fixed pulley block, the guide pulleys and the friction winches and wound on the corresponding platform lower fixed pulley block and the corresponding spud leg lower fixed pulley block through another group of guide pulleys, the tail end of each steel wire rope is fixed on the corresponding lifting mechanism chamber, and the steel wire ropes, the pulley blocks and the friction winches form a closed circulation system. The self-elevating offshore wind turbine installation vessel has the advantages that the installation vessel is small in size, smooth and continuous in motion, fast in lifting, convenient to maintain and applicable to wind power installation in shoaling water, and has a wide market prospect.

Description

technical field [0001] The invention relates to an offshore platform and a large ship, in particular to a self-elevating offshore fan installation ship. Background technique [0002] Wind turbine installation ship, also known as offshore wind farm engineering ship, windmill installation ship, is a dedicated offshore wind turbine installation engineering ship that integrates transportation, lifting, lifting and navigation functions. The ultra-large jack-up wind power installation vessel belongs to the second-generation offshore wind power installation engineering vessel. [0003] There are two main designs of existing self-elevating installation ship pile legs: shell type and truss type. The advantage of the shell type is that the structure is simple, easy to manufacture, and the strength is mainly realized by using ultra-high and ultra-thick strength plates. Compared with the truss type structure, it occupies a small area of ​​the hull, but its area affected by wind and wav...
