Abstract

The present invention relates to the technical field of marine engineering, and discloses a continuously working marine drilling tool, which includes a drill bit, and a fixed plate is fixedly installed on the outer edge of the drill bit, and a first thread tooth is provided on the outer wall of the fixed plate. The inner wall of the fixed piece is movably connected with a first movable rod. The present invention can adjust the diameter value of the drill bit according to the resistance value of the seawater during the process of lowering the equipment by adopting the organizational components of the fixing piece, the fixed piece, the limit block and the first movable rod, so that the diameter value of the drill bit can be adjusted during the lowering process. The water resistance value is reduced, and the inside of the drilling tool is hollowed out to reduce the blocked area during use, thereby achieving the effect of deeper diving depth and faster diving speed, effectively improving the performance of the equipment. The working depth is high, and its maximum diameter can fit the drilling tool, so that it can be seamlessly connected with the drilling tool during use, so that silt will not enter the interior during use.

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 ...
