Suction cylinder penetration method based on magnetic force
The invention belongs to the field of offshore wind power engineering, and particularly relates to a suction cylinder penetration method based on magnetic force, which comprises the following steps of: hoisting a guide frame to a seabed; a suction barrel is placed in the guide frame; mounting a magnetic propeller; current which enables the electromagnet module to generate repulsive force on the permanent magnet module is introduced into the electromagnet module, the electromagnet module downwards repulls the permanent magnet module, and the permanent magnet module pushes the attraction barrel to penetrate into the seabed; and after penetration is completed, the magnetic propeller and the guide frame are detached. Compared with a negative pressure penetration method, the suction cylinder penetration method based on magnetic propulsion has the advantages that no pressure difference exists inside and outside the cylinder, during installation, the two sides of the suction cylinder are not subjected to transverse pressure, the cylinder wall is not prone to buckling, a space is provided for optimizing the thickness of the cylinder wall, the cylinder structure cost can be further reduced, no obvious pressure difference exists between seawater in the cylinder and seabed soil, and the service life of the suction cylinder is prolonged. And the problem of soil blockage is not easy to occur.
本发明属于海上风电工程领域，具体涉及一种基于磁力的吸力筒沉贯方法，包括：将导向架吊装至海床；在导向架中放入吸力筒；安装磁力推进器；给电磁铁模块通入使其能够对永磁铁模块产生排斥力的电流，电磁铁模块向下排斥永磁铁模块，通过永磁铁模块推动吸力筒贯入海床；沉贯完成后拆除磁力推进器和导向架。本发明提出了一种基于磁力推进的吸力筒沉贯方法，相较于负压沉贯方法，筒内外无压差，安装时，吸力筒两侧不会受横向压力，筒壁不易屈曲，为优化筒壁厚度提供空间，可进一步降低筒结构成本，且筒内海水与海床土体无明显压强差，不易发生土塞问题。
