Seabed autonomous drilling and anchoring device and method for offshore floating type wind driven generator
The invention discloses a seabed autonomous drilling and anchoring device for an offshore floating type wind driven generator. The device is composed of a drilling module, a pressurization module, a chip removal module, an anchoring module and a laying module. The drilling module crushes a seabed rock stratum; the pressurizing module is used for increasing drilling thrust; the chip removal module is used for crushing, lifting and discharging rock chips; the anchoring module fixes and recycles the device; the laying module is used for taking up and paying off the cable. The hollow drill bit is adopted in the middle of the device, and rock debris migration and autonomous rock debris removal are achieved; a spiral mechanism is arranged in the middle of the device to realize secondary crushing, transportation and lifting of rock debris; pressurization in the drilling process is achieved through a crank connecting rod mechanism; and an anchoring mechanism and a drill bit separating mechanism are designed to recycle the drill bit module. According to the device, seabed autonomous drilling and anchoring of the offshore floating type wind driven generator are achieved, the drilling efficiency and the drilling speed of the device are improved, the chip removal efficiency of the device is improved, rock chips are prevented from blocking a channel, and compared with other seabed piling and anchoring modes, the device is simpler, more convenient, more efficient and safer.
本发明公开了一种海上浮式风力发电机海底自主钻进锚定装置。该装置由钻进模块、增压模块、排屑模块、锚定模块和布放模块组成。钻进模块破碎海床岩层；增压模块增加钻进推力；排屑模块破碎、举升与排出岩屑；锚定模块固定与回收装置；布放模块收放电缆。本发明采用空心钻头在装置中间实现了岩屑运移自主排除岩屑；装置中间设置螺旋机构实现了岩屑二次破碎和运移举升；采用曲柄连杆机构实现钻进过程中的增压；设计锚定机构和钻头分离机构实现钻头模块的回收。本发明实现了海上浮式风力发电机海底自主钻进和锚定，提高了装置的钻进效率和钻进速度，改善了装置排屑效率，防止了岩屑堵塞通道，比其他海底打桩锚定的方式更加简便、高效、安全。
