Problems solved by technology

This construction method has the following disadvantages: 1. The bulk transportation of the nacelle, hub, and blades of large-scale wind turbines requires a large overall area and requires a 10,000-ton large transport ship. The construction cost is high, which is not conducive to saving costs; 2. Spare parts After the unit is transported to the installation site, it is necessary to assemble the engine room, hub, and blades on site, requiring a large operating platform, low safety factor and slow speed for offshore operations; 3. Affecting construction safety

Embodiment 1

[0031] Such as Figure 1 to Figure 6 As shown in the figure, an integrated transportation device for offshore wind turbine engine room impeller assembly includes a transport ship, and also includes a transport support unit and a hub support unit arranged on the transport ship. The transport support unit includes a steel frame 1 and a mounting seat 2, and the steel frame 1 It is a rectangular frame made of welded transverse channel steel and longitudinal channel steel. The steel frame 1 is detachably connected to the transport ship through bolts. The mounting seat 2 is fixedly connected to the steel frame 1. The mounting seat 2 is hollow. There are several connecting components, which are connected and fixed to the engine room by using several connecting components. The hub support unit is arranged on the inner side of the mounting base 2 and includes a fixing base 3, a support rod 4 and a pin shaft 5. The fixing base 3 is fixedly connected to the deck of the transport ship. On...

Embodiment approach

[0039] An implementation method of an integrated transport device for an offshore wind turbine nacelle impeller assembly, comprising the following steps:

[0040] S1. First dock the transport ship at the sea transport wharf, weld the steel frame 1 of the pre-fabricated transport bracket unit to the proper position of the transport ship, and use the pre-fabricated hub support unit to weld the fixed seat 3 under the middle of the mounting seat 2 appropriate position on the deck of the transport vessel;

[0041] S2. Use a crawler crane to assemble the hub and blades on the dock site to form an impeller, then combine the nacelle and the impeller into a "rabbit head" overall shape, and use a crawler crane to assemble the assembled nacelle and impeller. "Rabbit head" is hoisted on the mounting seat of the transport bracket unit of the transport ship, and the lower extrusion part pushes the pressure plate to move towards the center of the mounting seat, so that the pressure plate hug...

Abstract

The invention discloses a cabin and impeller combination transportation device for an offshore wind turbine and an implementation method, and belongs to the technical field of wind power generation transportation devices. According to the cabin and impeller combination transportation device for the offshore wind turbine, a steel truss, a mounting seat, a fixing seat, a supporting rod and a pin arearranged, a steel frame and the mounting seat are used as a transportation base table of a cabin and an impeller, a connecting assembly on the mounting seat is used for fixing the cabin, the fixing seat is rotatably connected with the supporting rod through the pin, the end, far away from the fixing seat, of the supporting rod extends into the interior of the cabin and is connected with an internal impeller flange by using a tensioning assembly for auxiliary reinforcement, the safety in the transportation process is improved, the structure is simple, the practicability is high, and the transportation cost is saved.

Description

technical field [0001] The invention belongs to the technical field of wind power generation transportation equipment, and in particular relates to a transportation device for an offshore wind power generator nacelle impeller assembly and an implementation method. Background technique [0002] With the increasing scarcity of world energy and the rapid development of science and technology, coupled with people's requirements for environmental protection, people are trying to find a renewable, environmentally friendly and clean green energy that can replace oil, natural gas and other energy. Wind energy is currently the most promising new type of energy. It is an inexhaustible energy source and a clean, pollution-free, renewable green energy source. [0003] my country's coastal areas are rich in wind resources, with a coastline of more than 18,000 kilometers and more than 6,000 islands. Offshore wind energy resources are mainly concentrated in the southeast coast and its nea...
