Embodiment 1

[0041] A bionics-based dynamic torpedo anchor includes an anchor wing 1, an anchor rod 2, a rotating anchor tip 3, and a simple water ramjet. The simple water ramjet engine is divided into the water ramjet engine at the anchor rod and the water ramjet engine at the anchor tip. The water ram press engine at the anchor rod is composed of anchor metal solid material bin 9, anchor rod water bin 10, anchor rod water bin water inlet 11, anchor rod metal solid material bin water inlet 12, anchor metal solid material bin filter screen 13, anchor Rod exhaust bin 14, anchor rod water bin water inlet plug 18 and anchor rod end exhaust port 5 are formed. The water ramjet engine at the anchor tip consists of an anchor tip metal solid material bin 15, an anchor tip water inlet 16, an anchor tip metal solid material bin filter screen 17, an anchor tip water inlet plug 20, an anchor tip exhaust channel 21 and an anchor tip exhaust port 6 composition. Anchor rod metal solid material bin 9 is...

Embodiment 2

[0043] A method for installing a dynamic torpedo anchor according to the present invention mainly includes the following steps:

[0044] First, install the metal solid material bin 9 at the anchor rod 2 and the rotating anchor tip 3 before the anchor body is lowered. The length of anchor rod 2 is 12.0m~17.5m (12.5m in this embodiment), the anchor diameter is 0.75m~1.20m (1m in this embodiment), and the width of anchor wing 1 is 0.5m~1.5m (the present embodiment is 1.2m), the length of the anchor wing 1 is the anchor length of 1 / 3~2 / 3 (this embodiment is the anchor length of 1 / 2), the thickness of the anchor wing 1 is 0.07m~0.08m (the present embodiment is 0.08m) In this embodiment, the rotating anchor tip 3 is 2.5m long, and 1 to 5 honeycomb metal negative Poisson's ratio materials are added to the anchor wing (this embodiment is an overall addition) and the thickness is 0.02m to 0.03m (0.02m in this embodiment) , the maximum diameter of the vertical projection of the anchor ...

Embodiment 3

[0053] A method for installing a dynamic torpedo anchor according to the present invention mainly includes the following steps:

[0054] First, install the metal solid material bin 9 at the anchor rod 2 and the rotating anchor tip 3 before the anchor body is lowered. The length of the anchor rod 2 is 12.0m, the anchor diameter is 0.75m, the width of the anchor wing 1 is 0.5m, the length of the anchor wing 1 is 1 / 3 of the anchor length, and the thickness of the anchor wing 1 is 0.07m. 2.5m, add 1 to 5 pieces of honeycomb metal negative Poisson’s ratio material to the anchor wing (this embodiment is an overall addition) with a thickness of 0.03m, the maximum diameter of the vertical projection of the anchor tip 3 and the spiral blade is 1m, and the metal solid material bin Installed at the top 1 / 2 of the anchor rod 2.

[0055] Secondly, hoist the anchor body to the designed drop height of 150m.

[0056] Then, after removing the water inlet plug 18 of the anchor rod water tank ...

Abstract

The invention discloses a bionics-based dynamic torpedo anchor and an installation method thereof, belonging to the technical field of deep-sea mooring. Including rotating anchor tip, anchor rod, anchor wing and simple water ramjet engine part; the invention combines the traditional torpedo free-fall movement and installs the simple water ramjet engine at the same time, so that it can obtain a greater initial penetration speed and improve the penetration rate of the torpedo anchor. Depth; add negative Poisson’s ratio materials to the anchor rod and anchor wing, and use the characteristics of negative Poisson’s ratio materials to shrink under compression and expand under tension to reduce penetration resistance and improve uplift bearing capacity. The invention has the advantages of high initial penetration speed, deep installation penetration and high pullout bearing capacity.

Description

technical field [0001] The invention belongs to the technical field of deep sea mooring, in particular to a bionics-based dynamic torpedo anchor and an installation method thereof. Background technique [0002] In recent years, with the gradual advancement of offshore energy exploitation to the deep sea, the mooring system suitable for deep-sea oil production platforms has attracted extensive attention from the marine industry. Torpedo anchors have been widely used in marine engineering construction because of their advantages of simple installation, easy operation and low cost. [0003] Negative Poisson's ratio material is a kind of metamaterial with opposite characteristics to traditional positive Poisson's ratio material. It expands perpendicular to the direction of tension when it is pulled, and shrinks perpendicular to the direction of pressure when it is compressed. Researchers first proved the existence of negative Poisson's ratio characteristics in pyrite crystals; ...
