Offshore wind power installation platform

Abstract

The invention discloses an offshore wind power installation platform, and belongs to the field of marine wind power. Except a platform body, a gear and rack lifting system and truss pile legs, the offshore wind power installation platform further comprises sunk pads, circular pile legs and connecting assemblies, the circular pile legs are connected with the truss pile legs, the sunk pads are fixedto the circular pile legs, and the distance between one end of each circular pile leg and the surface, deviating from the truss pile legs, of the corresponding sunk pad is larger than the thickness of the sunk pads in the axial direction of the circular pile legs. The installation platform can be smoothly inserted into the seabed through conical protrusions on the circular pile legs, good fixation of the position of the installation platform is realized, the sunk pads of the box-type structures are attached to the seabed, the circular pile legs and the suck pads have good resistance to the action force in the radial direction and the axial direction of the circular pile legs, the installation platform is well supported, and working stability of the offshore wind power installation platform is improved. The truss pile legs and the circular pile legs are connected through the connecting assemblies, the axis of the truss pile legs coincides with the axis of the circular pile legs, the stable connection between the circular pile legs and the truss pile legs can be ensured, and the work stability of offshore wind power installation is guaranteed.

Description

Technical field [0001] The invention relates to the field of marine wind power, in particular to an offshore wind power installation platform. Background technique [0002] The offshore wind power installation platform is used to realize the installation of offshore wind turbines, and has a good role in promoting the development of the offshore wind power field. The offshore wind power installation platform includes at least the platform, truss legs, pile boots and rack and pinion lifting systems. The truss legs and the pile boots are usually fixedly connected as a whole. The platform and the truss legs are detachably connected, and the truss legs and the pile boots Insert the seabed to support the platform, and the rack and pinion lifting system controls the platform to move up and down. [0003] The current offshore wind power installation platform is usually large in volume and tapered structure, which is convenient for the pile shoes to be inserted into the seabed and can prov...

AI Technical Summary

Problems solved by technology

[0003] The current offshore wind power installation platform is usually large in size and has a conical structure, which is convenient for spud cans to be inserted into the seabed and can provide good support for the platform. However, for offshore wind power installation platforms that are affected by large wind waves in offshore wind fields , when the spud cans are inserted into the seabed and the platform is working normally, the support capacity of the spud cans is poor, which will affect the stable operation of the offshore wind power installation platform
