A ring barbed torpedo anchor

Abstract

The invention discloses a torpedo anchor with ring spines. The torpedo anchor comprises an anchor body, an anchor head, tail vanes, a working anchor chain and a puncture mechanism, wherein the conical anchor head is arranged at the lower end of the anchor body; four tail vanes are symmetrically arranged at the periphery of the anchor body; the upper end of the anchor body is of a hollow cavity; the puncture mechanism is arranged inside the cavity and comprises a base, connecting rods, puncturing-out rods and a puncture anchor chain connecting nose; the working anchor chain extends into the hollow cavity; the lower end of the working anchor chain is connected with the puncture anchor chain connecting nose. According to the device, the puncture mechanism in the torpedo anchor can be promoted by using a tensile force borne by the working anchor chain to drive spines on the puncture mechanism to pierce into a soil body, thereby widening the influenced soil body range; meanwhile, a punctured upper surface is a plane; the soil body covering the punctured upper surface can provide newly-increased pressure after the punctured upper surface pierces into the soil body; by improvement on two aspects, the uplift bearing capacity of the torpedo anchor is remarkably improved, so that the torpedo anchor becomes a deep-water mooring foundation with higher stability and safety.

Description

technical field [0001] The invention relates to a mooring foundation device, in particular to a torpedo anchor with ring barbs. Background technique [0002] With the development of human society, the exploration of the ocean is getting deeper and deeper. The sea area involved is getting wider and wider, and the water depth is also increasing. In the process of energy exploitation and other activities in ultra-deep waters, the requirements for deep-water mooring base are getting higher and higher, which should not be too expensive and have sufficient carrying capacity. Among many deep-water mooring foundations, the anchor mooring foundation has high pull-out resistance, and the torpedo anchor is a new deep-water mooring system that is easy to install and low in cost. The torpedo anchor falls freely by its own weight and penetrates into the soil. During its installation, no other launching devices are needed, and the installation is very convenient. At the same time, the m...
