Description

Technical Field

[0001] This utility model relates to an integrated towing tugboat assembly and distribution structure for floating wind turbine units, belonging to the field of offshore wind power construction technology. Background Technology

[0002] With the continued growth of global energy demand and the increasing awareness of environmental protection, wind energy, as a renewable and clean energy source, has gradually gained attention from various countries. Floating wind turbines, in particular, are becoming a popular direction for wind energy development because they can be deployed in deep-sea areas, avoiding problems such as land scarcity and landscape impact associated with near-shore wind farms. However, the deployment of floating wind turbines requires towing them to their installation locations.

[0003] There is an existing method for towing floating wind turbines, as described in Chinese Patent Publication No. CN114030567A. Although it can be towed forward by two tugboats positioned in front of the buoyancy base, it cannot push the buoyancy base to change direction. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a floating wind turbine integrated towing tugboat grouping and distribution structure.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides an integrated floating wind turbine towing tugboat assembly and distribution structure, including:

[0007] Floating body of the wind turbine.

[0008] The wind turbine float is triangular in shape.

[0009] The triangular wind turbine float extends outwards at both ends, with slow-speed tugboats symmetrically connected by towing cables. The two slow-speed tugboats symmetrically tow the wind turbine float forward to accelerate it.

[0010] It also includes two symmetrically distributed pusher tugboats, which are positioned on either side of the front end of the wind turbine buoy between the two slow-speed crane tugboats.

[0011] A fan is installed on the fan float.

[0012] It also includes stern crane tugs, which are relatively slow crane tugs distributed behind the wind turbine float. The stern crane tugs are two symmetrically distributed tugs that tow the wind turbine float backward to slow it down. The two stern crane tugs are connected to the connection points between the two slow crane tugs and the wind turbine float on both sides by tow cables.

[0013] Emergency tugboats are located at both ends of the outward-expanding buoy of the wind turbine.

[0014] The beneficial effects of this utility model are as follows: the wind turbine float is towed forward by a slow-speed tugboat to accelerate its movement. During the towing process, it can be pushed and steered by the tugboat, which solves the technical problem that the existing technology cannot push and steer the buoyancy base.

[0018] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0019] like Figures 1 to 2 As shown.

[0020] This application discloses a floating wind turbine integrated towing tugboat assembly and distribution structure, comprising:

[0021] The top surface is equipped with a fan 1 and a fan float 2 (also called a buoyancy base), which is arranged in a triangular pattern.

[0022] The triangular wind turbine float 2 has two outwardly extended ends symmetrically connected to slow-speed tugboats 3 via towing cables. The two slow-speed tugboats 3 symmetrically tow the wind turbine float 2 forward to accelerate it.

[0023] It also includes two stern crane tugboats 4 that are relatively slow crane tugboats 3 distributed behind the wind turbine float 2. The two stern crane tugboats 4 are symmetrically distributed to tow the wind turbine float 2 backward and decelerate it. The two stern crane tugboats 4 are connected to the connection points of the two slow crane tugboats 3 and the wind turbine float 2 on both sides by tow cables.

[0024] It also includes two symmetrically distributed pusher tugboats 5, which are located on both sides of the front end of the wind turbine float 2 between the two slow-speed crane tugboats 3. The two pusher tugboats 5 push and change the direction of the wind turbine float 2 towards the front end.

[0025] Emergency tugboats 6 are located at both ends of the outward-expanding wind turbine float 2. These emergency tugboats 6 serve as backup tugboats and can be used to laterally push the wind turbine float 2 to change direction or to propel it forward to increase speed. The emergency tugboats 6 can also be connected to the wind turbine float 2 via tow cables for rear towing and deceleration.

[0026] The wind turbine float 2 of this application is towed forward by a slow-speed tugboat 3 to accelerate its movement. During the towing process, it can be pushed and steered by a pusher tugboat 5, which solves the technical problem that the existing technology cannot push and steer the buoyancy base.

[0027] When the wind turbine buoy 2, equipped with wind turbine 1, passes through the Huangchuan Marine Engineering Port Basin to the branch channel of the CSSC Longxue Shipbuilding Base, the wind turbine buoy 2 is slowly towed out of the port basin from the windward arm direction. In this operation, the length of the towing cable is controlled within 20 to 50 meters according to the on-site water flow and tide conditions.
