Such a setting can make the transportation process of the floating wind power foundation structure 8 more convenient and faster, effectively improve the launching rate of the floating wind power foundation structure, and improve the efficiency of the batch and large-scale launching of the floating wind power foundation structure in deep sea areas.

[0049] Further, according to an embodiment of the present invention, the lifting platform 2 further includes: a visual camera module and a control module (not shown in the figure);

[0050] The visual camera module is arranged on a side of the lifting platform 2 close to the transport platform 1. The visual camera module identifies and obtains the volume size of the floating wind power foundation structure 8 on the transport platform 1, and then transmits the volume size information to the control module;

[0051] After receiving the volume size information, the control module starts the lifting modules corresponding to the volume size to undertake and transport the floating wind power foundation structure into the water.

[0053] Further, according to an embodiment of the present invention, the visual camera module is arranged on the top of a group of lifting modules adjacent to the transport platform 1, and is arranged toward the table of the transport platform 1. Such an arrangement enables the visual camera module to accurately capture and measure the shape and size of the base structure supported on the table of the transport platform 1, making the measurement more specific and accurate, effectively reducing the error of the measurement result, and ensuring that the process of coordinating the lifting and launching into the water is more accurate.

[0054] Further, according to an embodiment of the present invention, when a group of lifting modules independently undertakes the floating wind power foundation structure or multiple groups of lifting modules cooperate to undertake the floating wind power foundation structure, the projection of the receiving surface formed by the group of lifting modules or multiple groups of lifting modules covers the floating wind power foundation structure. With such an arrangement, the receiving surface of the lifting module used to support the floating wind power foundation structure can always be larger than the cross-sectional area of ​​the floating wind power foundation structure, so that the support of the floating wind power foundation structure can be more stable and reliable, and the center of gravity is always above the lifting platform 2, ensuring a safe and stable launching process, effectively improving the launching efficiency, and ensuring construction safety.

[0055] Furthermore, if Figure 1-Figure 3 As shown, in this embodiment, each group of lifting modules includes: a platform deck 4, a platform column 5 and a lifting mechanism;

[0056] Both ends of the platform deck 4 are slidably connected to a platform column 5 respectively;

[0057] The lifting mechanism is supported on two platform columns 5 at both ends of the platform deck 4, and is connected to the platform deck 4, driving the platform deck 4 to move up and down along the two platform columns 5. Such an arrangement can make the lifting mechanism drive the platform deck 4 to move up and down more stably and reliably, and the two ends of the platform deck 4 are evenly stressed, ensuring the stability and safety of the launching process of the floating wind power foundation structure.

[0058] Furthermore, in this embodiment, the platform deck 4 is a hollow box structure. This arrangement can effectively reduce the weight of the platform deck 4 while stably supporting the floating wind power foundation structure, ensuring that the structural pressure of the lifting system is smaller and the service life is longer.

[0059] Furthermore, if Figure 1 , Figure 2 As shown, in this embodiment, the lifting mechanism includes: a winch 6 and a steel cable 7;

[0060] The winch 6 is supported on the top of each platform column 5;

[0061] The steel cable 7 is wound on the winch 6, and the free ends are respectively located on both sides of each platform column 5 and connected to both sides of the end top surface of the platform deck 4.

[0066] The transport platform 1 transports the floating wind power foundation structure carried thereon to the lifting modules with corresponding number of lifting modules;

[0067] After the floating wind power foundation structure is in place, the lifting platform 2 drives the floating wind power foundation structure into the water.

[0068] With such an arrangement, the operator can operate the lifting module on the transport platform to lower it. After the floating wind turbine foundation structure is lowered to a certain water depth together with the lifting module, the floating wind turbine foundation structure relies on its own buoyancy to separate from the lifting module. After the tugboat leads the floating wind turbine foundation structure to leave the lifting area of ​​the lifting module, the operator operates the lifting module to lift it and wait for the subsequent floating wind turbine foundation launching operation.

[0069] According to the above scheme of the present invention, the present invention effectively solves the cost and construction period control problems of launching a floating wind power platform by using a lifting device to assist the integrated launching of a floating wind power foundation structure, realizes the possibility of launching floating wind power foundation structures in batches and on a large scale, solves the difficulty of launching a floating offshore wind power as a whole, and improves the efficiency of floating offshore wind power construction.
