AI Technical Summary

Benefits of technology

This technology allows for faster and deeper drilling by combining weighted piles with an electric current through it. It also includes a simpler mechanism that uses less expensive materials like rubber or plastic instead of traditional steel rods. Additionally, this combination can be used on both land and sea floors where conventional methods cannot work well due to poor ground conditions such as sandy seas without causing damage from excessive force applied during use.

Problems solved by technology

This patented technical problem addressed in this patents relates to developing a better understanding about hydraulically driven thrust reversible pump/liner design for use in submarines without causing environmental pollution issues such as hydrogen sulfide emissions. Current methods involve adding heavyweight iron powder called Weldonites® to improve buoyancy while also improving efficiency. These techniques include mixing different types of rocks together like clay sandwich plaster stones, creating void spaces within them, attaching rubbery steel sheets onto these surfaces, and installing nylons instead of polyimides.

Embodiment 1

[0041] A novel dynamic torpedo anchor based on bionics, comprising an anchor wing 1, an anchor rod 2, a rotating anchor tip 3, and a simple water ramjet engine. 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 soli...

Embodiment 2

[0043] A novel dynamic torpedo anchor installation method 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 ancho...

Embodiment 3

[0053] A novel dynamic torpedo anchor installation method 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 honeycomb metal negative Poisson’s ratio materials to the anchor wing (in this embodiment, the overall addition) is 0.03m thick, 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 and the water in...

Abstract

The invention discloses a novel dynamic torpedo anchor based on bionics and an installation method thereof, and belongs to the technical field of deep sea anchoring. The novel dynamic torpedo anchor comprises a rotary anchor tip, an anchor rod, anchor wings and a simple water ramjet engine part; According to the novel dynamic torpedo anchor based on bionics and the installation method thereof, thesimple water ramjet engine is started while the traditional torpedo free falling body movement installation is combined, so that the higher initial penetration speed is obtained, and the penetrationdepth of the torpedo anchor is increased; negative poisson ratio materials are additionally arranged on the anchor rod and the anchor wings, and the characteristics that the negative poisson ratio materials contract under pressure and expand under tension are utilized, so that the penetration resistance is reduced, and the uplift bearing capacity is improved. The novel dynamic torpedo anchor has the advantages of being high in initial penetration speed, deep in installation penetration and high in uplift bearing capacity.
