The invention provides a deep sea suction anchor, and belongs to the technical field of ocean engineering equipment, the suction anchor comprises a first anchor cylinder and a second anchor cylinder, the first anchor cylinder is a hollow cylinder with an opening in the bottom end, and the top of the first anchor cylinder is provided with a drainage hole used for being connected with external negative pressure equipment; the second anchor cylinder is slidably arranged on the first anchor cylinder in a sleeving mode, the length of the second anchor cylinder is smaller than that of the first anchor cylinder, and the second anchor cylinder and the first anchor cylinder are fixedly connected through a locking piece; under the external action, the locking piece can release the locking state of the first anchor cylinder and the second anchor cylinder, so that the second anchor cylinder slides relative to the first anchor cylinder. According to the deep sea suction anchor provided by the invention, the problem of anchored seabed erosion caused by the action of seabed water flow can be improved through the arranged second anchor cylinder, the anchoring action area is increased, and the overall stability of the suction anchor is improved.
本发明提供了一种深海吸力锚,属于海洋工程设备技术领域,该吸力锚包括第一锚筒和第二锚筒,其中,第一锚筒为底端开口的中空圆柱体,所述第一锚筒的顶部设置有用于与外部负压设备连接的排水孔;第二锚筒,可滑动的套设于所述第一锚筒上,所述第二锚筒的长度小于第一锚筒的长度,所述第二锚筒和所述第一锚筒通过锁紧件固定连接;在外部作用下所述锁紧件能够解除所述第一锚筒和所述第二锚筒的锁紧状态,以使所述第二锚筒相对所述第一锚筒滑动。本发明提供的深海吸力锚,通过设置的第二锚筒能够改善海底水流作用引起锚定后的海床冲蚀问题,增大锚定作用面积,提升吸力锚的整体稳定性。
