[0001] This application relates to the technical field of wind power generation, and particularly to an assembly device and process for a floating wind turbine. Background Art

[0002] A floating wind turbine is a power generation device that deploys a wind turbine generator on the deep - sea surface through a floating structure, such as a semi - submersible or column - type platform, and fixes its position using a mooring system. Its working principle is that the wind energy is captured by the wind turbine blades, driving the generator to convert kinetic energy into electrical energy. The electrical energy is transmitted to an offshore substation through an underwater cable and then to the on - shore power grid.

[0003] In the prior art, the assembly mode of a floating wind turbine is generally to assemble the wind turbine and the lower floating body at the quay front. During this process, the floating body constantly sways in the sea waves, while the crane on the quay remains stationary. There is a situation of "static" against "dynamic" during the wind turbine hoisting process, which has strict requirements for the window period and is not convenient for the hoisting of the wind turbine. Therefore, this application provides an assembly device and process for a floating wind turbine, making the floating body relatively stationary with respect to the quay to facilitate the assembly of the floating wind turbine. Summary of the Invention

[0004] In order to improve the stability during the assembly process of a floating wind turbine, this application provides an assembly device and process for a floating wind turbine.

[0005] In a first aspect, an assembly device for a floating wind turbine provided by this application adopts the following technical solution:

[0006] An assembly device for a floating wind turbine includes a bottom platform and a number of buoyancy cylinders provided on the bottom wall of the floating body. The bottom platform is arranged on the seabed, and a number of anchor piles for fixing are provided at the bottom of the bottom platform. A number of positioning cylinders are arranged on the surface of the bottom platform. The positioning cylinders and the buoyancy cylinders are in one - to - one correspondence. Traction rings are provided on the surface of the positioning cylinders and the bottom wall of the buoyancy cylinders. It also includes a number of steel wire ropes, which are in one - to - one correspondence with the positioning cylinders and the buoyancy cylinders. The steel wire ropes sequentially pass through the traction rings on the positioning cylinders and the buoyancy cylinders and are connected to an anchor boat.

[0007] By adopting the above - mentioned technical solution, the steel wire ropes can keep the bottom platform and the floating body vertically aligned, thus ensuring the stability of the floating body, reducing the situation of "static" against "dynamic" of the floating body during the installation of the floating wind turbine caused by sea - wave impact, improving the problem of strict requirements for the window period in the prior art during the hoisting of the wind turbine, and enhancing the convenience and assembly quality of the floating wind turbine assembly.

[0008] Preferably, a plurality of adjusting grooves are formed in the surface of the bottom platform corresponding to the positioning cylinders. The plurality of adjusting grooves are all arranged towards the center direction of the bottom platform. Each adjusting groove is slidably connected with an adjusting block, and the adjusting block is connected to the corresponding positioning cylinder for driving the positioning cylinder to move along the length direction of the adjusting groove. A driving mechanism for driving the plurality of adjusting blocks to move together is arranged in the bottom platform.

[0009] By adopting the above technical solution, the adjusting grooves are formed, and the adjusting blocks and the driving mechanism are arranged, so that the position of the positioning cylinder can be adjusted according to the size of the floating body, thereby improving the applicability of the buoyancy fan assembly device of the present application.

One end of the driving screw passes through the adjusting groove and is inserted into the driving cavity. The second bevel gear is sleeved on the peripheral wall of one end of the driving screw located in the driving cavity. The second bevel gear is meshed with the corresponding first bevel gear.

[0011] By adopting the above technical solution, when the driving motor is started, it drives the main gear to rotate. The corresponding first bevel gear is driven to rotate by the transmission relationship between the main gear and the sub-gear. Due to the transmission relationship between the first bevel gear and the second bevel gear, the driving screw rotates, so that the adjusting block can be driven to move along the length direction of the adjusting groove, and further the adjustment of the positioning cylinder is realized. The driving mechanism of the present application has a simple structure, is easy to implement, and has high convenience and applicability.

[0012] Preferably, guiding grooves are formed on both sides of each adjusting groove. The length direction of the guiding grooves is consistent with the length direction of the adjusting grooves.

[0019] By adopting the above technical solution, the guide wheels are arranged to reduce the wear of the steel wire rope, prolong the service life of the steel wire rope, and reduce the problem that the steel wire rope breaks during work and affects the balance of the floating body.

[0020] In a second aspect, the present application further provides an assembling process of a floating wind turbine, including the following steps:

[0021] Use a tugboat to transport the bottom platform to the assembling site of the floating wind turbine. Pass a steel wire rope through the towing ring of the positioning cylinder on the bottom platform, sink the bottom platform to the seabed, and fix the bottom platform with anchor piles.

[0026] After the assembly is completed, release the steel wire ropes used to position the bottom platform and the floating body and recover the bottom platform.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The steel wire rope can keep the bottom platform and the floating body vertically up and down, thus ensuring the stability of the floating body, reducing the "static" against "dynamic" situation of the floating body during the installation of the floating wind turbine caused by the impact of sea waves, improving the problem that the window period is strictly required during the hoisting of the wind turbine in the prior art, and enhancing the convenience and quality of the assembly of the floating wind turbine.
