Abstract

The invention relates to the technical field of marine engineering, and discloses a marine drilling tool capable of continuously working. The marine drilling tool capable of continuously working comprises a drill bit, wherein the outer edge of the drill bit is fixedly equipped with a fixed sheet; the outer wall of the fixed sheet is provided with first threaded teeth; and the inner wall of the fixed sheet is movably connected to a first movable rod. Structure components of a fixed part, the fixed sheet, a limiting block and the first movable rod are adopted, so that the diameter of the drill bit can be regulated according to a resistance value of seawater in an equipment dropping process, and therefore, the resistance value in the dropping process is reduced; a hollow-out type design is adopted inside the drilling tool, so that resistance area is reduced in a using process, and therefore, the effects of greater diving depth and higher diving speed are achieved, working depth of the tool is effectively increased; and moreover, the maximum diameter value can be fitted to the drilling tool, so that seamless butt-joint with the drilling tool can be achieved in the using process, and therefore, sludge does not enter the tool in the using process of the tool.

Description

technical field [0001] The invention relates to the technical field of ocean engineering, in particular to an ocean continuous working drilling tool. Background technique [0002] Marine engineering refers to new construction, reconstruction and expansion projects aimed at the development, utilization, protection and restoration of marine resources, and the main body of the project is located on the seaward side of the coastline. It is generally believed that the main content of marine engineering can be divided into two parts: resource development technology and equipment and facility technology, specifically including: sea reclamation, offshore dam engineering, artificial islands, offshore and submarine material storage facilities, cross-sea bridges, and submarine tunnel projects. Submarine pipelines, submarine electric (optical) cable projects, exploration and development of marine mineral resources and their subsidiary projects, marine energy development and utilization ...
