Great-depth seabed portable electric cutting device based on submersible

Abstract

The invention provides a great-depth seabed portable electric cutting device which can be loaded onto a 7000-meter manned submersible and conducts cutting and sampling on underwater ore. The device comprises a direct current motor and a reducer, the direct current motor and the reducer are fixed to an output shaft through a coupling and a bearing, and an oil charge cavity is formed in a shell body of a shell. The static sealing design is adopted between a front end cap of the shell and the shell, and one or more O-shaped rubber rings are arranged at the contact part between the front end cap and the shell; a rotating combination sealing ring is arranged at the contact part between a revolving shaft and the front end cap, the double-acting rotating seal is adopted for the rotating combination sealing ring, and the sealing pressure can reach 30 MP; the same static sealing design is adopted at a rear end cap of the shell, and one or more O-shaped rubber rings are arranged at the contact part between the rear end cap and the shell. By means of the device, the problems that existing great-depth underwater rock sampling mechanisms are difficult to sample or load, complex in structure, high in fabrication cost, hard to maintain and the like are solved, and the device has the advantages of being simple in fabrication, high in efficiency, safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of deep-sea resource exploration and development equipment, and in particular relates to a deep-sea portable electric cutting device based on a submersible. Background technique [0002] The deep sea area is rich in mineral resources, biological resources and a large number of indispensable resources for national economic development and national defense construction. The exploration and development of mineral resources in the seabed area, especially the deep sea area, requires the strong support of marine high technology. Exploration of deep seabed mineral resources is an indispensable major technology for ocean research and scientific investigation. Usually large-depth seabed rock sampling is that most adopt core sampling drilling rigs to carry out rock drilling and sampling, and the report of adopting the cutting of circular saw blade to sample has not yet been found. [0003] Over the past 50 years, re...
