Large-grip-type deep sea anchor

Abstract

The invention discloses a large-grip-type deep sea anchor which comprises an anchor chain, a rotating ring and an anchor handle. An anchor end chain is arranged at one end of the anchor chain. The anchor end chain is connected with the rotating ring through a bolt. The rotating ring is connected with the anchor handle through an anchor shackle. The tail end of the rotating ring is cylindrical. An external thread is arranged at the tail end of the rotating ring. A nut is installed on the anchor shackle. The rotating ring is screwed into the nut, the anchor handle is connected with an anchor head through a small shaft, and the anchor head is connected with anchor flukes through a transverse pin. According to the large-grip-type deep sea anchor, the center of gravity of the anchor is lowered, the anchor handle is of a slab structure, a double-screw bolt, an anchor blade and other structures are arranged on an anchor fluke arm, so that the engaging-in depth of the anchor is increased, the limit bearing capacity is improved, dynamic loads transmitted by mooring cables are balanced, the higher holding power to weight ratio of the deep sea anchor under various soil textures is ensured, and the effect of the large-grip-type deep sea anchor is brought into full play.

Description

technical field [0001] The invention relates to a deep-sea anchor with a large holding force and belongs to the field of ships and ocean engineering. Background technique [0002] With the development of modern marine development, the number and scale of various marine engineering structures are increasing day by day in the dotted seaports, and their operating scope and research direction are gradually developing to the deep sea. Anchor equipment is the sum of the devices and machinery used by ships and marine engineering structures when anchoring at sea. Although there are many types of anchors, their purposes are the same, mainly to use the anchor's grip to make the anchor tightly grasp the seabed, so that ships and marine engineering structures are not affected by wind, current, and wave impact. fixed in a certain position. However, the waves on the ocean are churning, the hurricane is raging violently, and the tide is surging. Under such a harsh operating environment, ...

AI Technical Summary

Problems solved by technology

However, the current research on deep-sea anchors with large holding power is very limited, and the existing technologies and devices are more researched and developed for inland waterway anchors and port anchors.
