Ship for transporting wind turbines and transporting method for wind turbines

Abstract

The invention relates to a ship for transporting wind turbines, and a transporting method for the wind turbines. According to the invention, a deck is arranged on the upper surface of the ship body; the ship comprises a support framework fixed on a longitudinal medial axis and provided with a top plane, two guide rails parallel to the longitudinal medial axis and respectively positioned on two sides of the support framework, two second guide rails parallel to the longitudinal medial axis and respectively positioned on the two sides of the top plane of the support framework, a move support block arranged on the first guide rails, used for supporting the wind turbines and driving the wind turbines to move along the first guide rails, support removal brackets arranged on the second guide rails, connected with stepped drums of the wind turbines, and capable of synchronously moving with the corresponding removal support blocks along the second guide rails, an upper part suspension bracket connected with the bottoms of the wind turbines and fixed with the corresponding removal support blocks, and hoisting device arranged at one end of the support framework, fixed on the longitudinal medial axis and used for hoisting and moving the wind turbines to the removal support blocks or a marine foundation. The invention can improve the marine mounting efficiency of the wind turbines, and gets small influences from sea conditions.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a ship for transporting wind turbines and a transport method for wind turbines. Background technique [0002] With the rapid development of the wind power industry, the development of onshore wind farms is becoming increasingly saturated. Offshore wind farms, with their advantages of high wind speed, low turbulence, and small wind shear, have become a field of wind power that urgently needs to be developed. In addition, with the gradual increase of the unit capacity of wind turbines, the volume and weight of each component of the wind turbines are also increasing, which makes it very difficult to transport wind turbines at sea and then install them on the offshore foundation. [0003] The existing technology for transporting wind turbines at sea is to use a transport ship to transport the components of the wind turbine, such as the tower, engine room, blades, etc., to the vic...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that using the existing technology to transport wind turbines at sea, since each component is transported separately to the vicinity of the offshore foundation, it is necessary to install the wind turbine in the harsh and changeable offshore environment. The static test and grid-connected commissioning of the whole machine must be carried out in the offshore environment, and because the existing technology requires the close cooperation between the transport ship and another ship equipped with a hanger, or with the offshore floating crane near the offshore foundation, it can be finally completed The installation of wind turbines, therefore, the existing technology results in low efficiency of installing wind turbines at sea, and is seriously affected by sea conditions. When sea conditions permit, it takes about 2-3 days to complete the installation of a wind turbine. Test and debugging takes longer
