Combined ring beam fixing device for offshore wind turbine foundation

Abstract

The invention relates to a combined ring beam fixing device for an offshore wind turbine foundation. The combined type ring beam fixing device for the offshore wind turbine foundation is simple in structure, convenient to manufacture and free of welding on the sea. According to the technical scheme, the device is arranged between a ring beam and a steel pipe pile, is used for fixing the ring beamto the steel pipe pile and is provided with a supporting connecting piece arranged between the ring beam and the steel pipe pile, and a ring beam supporting plate used for supporting the ring beam isfixed to the outer side face of the supporting connecting piece; the supporting connecting piece is provided with a long bending steel plate which is bent into sections A, B and C according to the radian of the outer diameter of the steel pipe pile; a connecting plate is arranged corresponding to each of the A section, the B section and the C section of the long bent steel plate, one end of each connecting plate is connected with the long bent steel plate through an elastic connecting piece, and a distance adjusting mechanism capable of adjusting the distance between the connecting plate and the long bent steel plate is arranged between the end, away from the elastic connecting piece, of each connecting plate and the long bent steel plate. The method is suitable for the technical field ofoffshore wind power.

Description

technical field [0001] The invention relates to a combined ring beam fixing device for offshore fan foundations. Applicable to the field of offshore wind power technology. Background technique [0002] As one of the most widely used foundation types in the field of offshore wind power engineering, monopile foundation has simple structure, fast construction and high cost performance. [0003] In order to avoid engineering safety risks caused by the connection failure of high-strength grouting materials, the Chinese patent No. 201210114192. In addition to the advantages of fast and cost-effective, it also eliminates the risk of connection failure between high-strength grouting materials and steel pipe piles; but the disadvantage is that the berthing system, cable pipes, sacrificial anodes and other auxiliary components are welded to the main structure, making installation difficult. It is easy to cause piling damage. [0004] Patent No.: ZL 201520060051.3 is a Chinese paten...

AI Technical Summary

Problems solved by technology

The offshore construction of this structure is fast, but the disadvantage is that the steel pipe piles of the integrated auxiliary structure and the main structure need to be welded, and the connection is difficult. The offshore welding not only has poor anti-corrosion effect, but also has weak anti-ship impact ability.
