A double-helix deep-sea formation autonomous drilling robot

Abstract

The invention relates to a drilling robot, in particular to a double-helix deep-sea formation autonomous drilling robot. Including the drill pipe; the front end of the drill pipe is connected to the drill bit through the drill collar; the sealed casing includes the front casing and the middle casing; the drill pipe is set in the sealed casing, and the middle part of the drill pipe is equipped with a driven bevel gear, and multiple sets are meshed with the driven bevel gear The active bevel gears are all connected to the main shaft motor; the inside of the drill pipe is hollow, and the spiral chip guide rod is welded inside the drill pipe; the round hole in the center of the chip removal piston is nested in the tail of the drill pipe, and the upper part of the piston is connected to the pusher in the middle casing. The output shafts of the motors are connected; there are two screw propellers, which are symmetrical and arranged on both sides outside the sealed casing along the axial direction. The control system is connected with the main shaft motor, the propulsion motor and the long shaft motor through composite cables. The whole robot of the present invention is an integrated design, has beautiful structure, is easy to assemble and effectively avoids the problem of interference during operation, and ensures the watertightness of the robot while realizing functions.

Description

technical field [0001] The invention relates to a drilling robot, in particular to a double-helix autonomous drilling robot used in deep seabed formations. Background technique [0002] The ocean is an important resource treasure house for human beings. The vast underwater world contains strategic resources such as abundant reserves of natural gas hydrates and manganese nodules, deep-sea oil and gas, and hydrothermal deposits. The development and utilization of seabed resources has gradually become a research hotspot. At the same time, the acquisition of seabed resources is also facing a series of technical problems. For example, during the trial production of natural gas hydrates in sea areas, it was found that the decomposition of natural gas hydrates would destroy the engineering mechanical structure of sediments, cause ground subsidence, and seriously cause geological disasters such as seabed subsidence, landslides and even earthquakes, threatening the safety of combusti...
