Problems solved by technology

The self-elevating ships or large-scale floating cranes used in the above two hoisting methods are both expensive to build, and the rental costs are particularly high, and the quantity is scarce. The installation cost has always been high, and it is difficult to meet the needs of large-scale development and construction of offshore wind power.

Embodiment Construction

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Embodiments of the present invention provide an installation device for offshore wind turbines, such as Figure 1-4 As shown, it includes a hull 1, an all-slewing crane 2, a slewing arm and a slewing mechanism 3. The full-slewing crane 2 is fixed on the hull 1, and a slewing arm is respectively arranged on both sides of the stern of the hull 1. The full slewing crane 2 is located between the two slewing arms. The slewing arm includes a forearm 5 and a rear arm 6 , the forearm 5 is slidably connected with the rear arm 6 , and the lifting mechanism 7 is fixed on the rear arm 6 and connected with the forearm 5 . The rear arm 6 is connected to the hull 1 through the slewing mechanism 3 , and the forearm 5 is normally located ...

Abstract

The invention provides an offshore wind turbine generator installation device which comprises a ship body, a full-rotation crane, rotation arms and a rotation mechanism, the full-rotation crane is fixed to the ship body, the two sides of a stern of the ship body are each provided with one rotation arm, the rotation arms are connected with the ship body through the rotation mechanism, and the rotation mechanism is fixed to the ship body. A plurality of floating foundation pressing mechanisms are arranged on the opposite sides of the two rotary arms respectively, and at least one floating foundation pressing mechanism is provided with a rotation driving mechanism. By capturing the floating foundation of the offshore wind turbine generator, the installation positions of equipment such as a tower drum and blades are accurately positioned, the influence of factors such as waves and wind power is reduced, the installation difficulty of the offshore wind turbine generator is reduced, and the installation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power generation, and in particular relates to installation equipment for offshore wind turbines. Background technique [0002] Wind power is currently a relatively fast-growing power generation industry. As the wind resources that can be developed on land are becoming less and less, the construction of global wind farms is gradually moving from land to sea. Because ocean wind energy has the advantages of rich resources, less dust, and higher wind speed, and offshore wind power generation does not occupy land area, the economic benefits of offshore wind power generation are 20%-40% higher than land wind power generation. At the same time, due to the small amount of sand and dust in the ocean wind, the wear and tear on the offshore wind turbines is relatively light during the process of wind power generation. This can greatly improve the service life of the offshore wind power generating set...
