Description

Technical Field

[0001] The invention relates to a method for installing blades of a wind turbine jacket based on a single row arrangement, and belongs to the technical field of installing offshore wind power blades of wind turbines. Background Art

[0002] With the continued development of offshore wind power, the efficiency of offshore wind turbine construction sometimes determines construction costs. Construction costs are often tied to the transportation of wind turbine components. Wind turbine blades and other components must be transported by ship to the offshore installation site (see Chinese Patent Publication No. CN117846884A). When winds and waves in the offshore construction environment become stronger, the ship transporting the blades must return to port to prevent damage to the blades.

[0003] At wind turbine installation sites far from the coast, ships transporting blades often return, resulting in reduced wind turbine installation efficiency and increased round-trip ship costs. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a method for installing blades of a fan duct frame based on a single row.

[0005] The present invention is achieved through the following technical solutions.

[0006] The present invention provides a method for installing blades on a fan duct frame in a single row, comprising: transporting the fan blades to the vicinity of the fan duct frame and independently placing them on the fan duct frame in a single row, and then hoisting and transferring them to an installation process for splicing with a nearby hub.

[0007] The installation process includes the following steps: fixing a tooling docking interface on the fan tower flange docking interface reserved on the fan duct frame, and also fixing a tooling docking interface on the fan duct frame platform surface, with six tooling docking interfaces on the blade transport ship and the fan duct frame, two in each group;

[0008] The blade transport vessel uses blade support fixtures to stably support the wind turbine blades and transport them to the sea area where the wind turbines are installed.

[0009] The installation process further includes the following steps: when sea winds and waves are expected, the wind turbine blades are not separated from the blade supporting tooling, the wind turbine blades are transferred to the adjacent wind turbine duct frame by a crane on the blade transport ship, the blade supporting tooling is fixed to the tooling docking interface through a flange port, so that the three wind turbine blades are placed in a single row on the wind turbine duct frame; the blade transport ship is moored away from the wind turbine duct frame to the nearby sea area.

[0010] The installation process further includes the following steps: when the sea surface reaches the construction conditions, the lifting deck platform is located near the wind turbine duct frame to be constructed, and the wind turbine hub is installed on the lifting deck platform. After the wind hub is installed, a blade transport ship moored in the nearby sea area transfers the wind blades from the wind turbine duct frame and transports them to the vicinity of the lifting deck platform. The blade transport ship also has a tooling docking port. At this time, the blade support tooling and the tooling docking port are docked and fixed through a flange port.

[0011] The installation process also includes the following steps: the wind turbine blades are separated from the blade support tooling on the blade transport ship, the wind turbine blades are docked and installed with the wind turbine hub by using a crane on the lifting deck platform, and the wind turbine hub with three wind blades installed is hoisted to the top of the wind turbine tower for docking and installation.

[0012] The beneficial effects of the present invention are that three wind turbine blades can be placed in a single row on the wind turbine duct rack, and the wind turbine duct rack provides a stable placement for the wind blades in a sea wind and wave environment, avoiding the need for the blade transport ship to return to the port carrying the wind blades when encountering sea wind and waves, ensuring that the components arrive on site in time during wind turbine construction, improving the wind turbine installation efficiency, and reducing the round-trip cost of the ship.

[0018] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0019] like Figures 1 to 4 shown.

[0020] The present application provides a method for installing blades on a single-row fan duct frame, comprising the following steps.

[0021] The blade transport ship 1 stably supports the wind turbine blades 2 through the blade supporting tooling 11 and transports them to the wind turbine installation sea area. A tooling docking interface 41 is fixedly installed on the wind turbine tower flange docking interface 4 reserved on the wind turbine duct frame 3, and a tooling docking interface 41 is also fixedly installed on the platform surface of the wind turbine duct frame 3. There are six tooling docking interfaces 41 on the blade transport ship 1 and the wind turbine duct frame 3, and they form a group of two.

[0022] When sea winds and waves are foreseen, the wind turbine blades 2 are not separated from the blade supporting fixtures 11. The wind turbine blades 2 are transferred to the adjacent wind turbine duct frame 3 by the crane on the blade transport ship 1. The blade supporting fixture 11 is fixed to the fixture docking port 41 through the flange port, so that the three wind turbine blades 2 are placed in a single row on the wind turbine duct frame 3; the blade transport ship 1 is moored in the nearby sea area away from the wind turbine duct frame 3.

[0023] When the sea surface reaches the construction conditions, the lifting deck platform 5 is located near the wind turbine duct 3 to be constructed, and the wind turbine hub 6 is installed on the lifting deck platform 5. After the installation of the wind turbine hub 6 is completed, the blade transport ship 1 moored in the nearby sea area transfers the wind blades 2 from the wind turbine duct 3 and transports them to the vicinity of the lifting deck platform 5. There is also a tooling docking port 41 on the blade transport ship 1. At this time, the blade support tooling 11 is docked and fixed to the tooling docking port 41 through the flange port.

[0024] Then, the wind blade 2 is separated from the blade supporting tooling 11 on the blade transport ship 1, and the wind blade 2 is docked and installed with the wind turbine hub 6 by using the crane on the lifting deck platform 5. The wind turbine hub 6 with three wind blades 2 installed is lifted to the top of the wind tower 7 for docking and installation.

[0025] The three wind turbine blades 2 can be laid out in a single row on the wind turbine duct 3. The wind turbine duct 3 provides a stable placement for the wind blades 2 in a sea wind and wave environment, avoiding the need for the blade transport ship 1 to return to the port carrying the wind blades 2 when encountering sea wind and waves. This ensures that the components arrive on site in a timely manner during wind turbine construction, improves wind turbine installation efficiency, and reduces round-trip ship costs.

[0026] The present application realizes transporting the wind turbine blades 2 to the wind turbine duct frame 3 for placement, and then hoisting and transferring them to be spliced ​​with the nearest hub 7 .
