Abstract

The invention discloses a sealing device for an underwater speed reduction drive mechanism. The sealing device comprises a sealed cabin, and a sealing head device which is in sealed connection with the sealed cabin; the sealed cabin comprises a first sealed cabin, and a second sealed cabin which is in sealed connection with the first sealed cabin, and the first sealed cabin and the second sealed cabin form a connected inner cavity after sealed connection. The sealing device for the underwater speed reduction drive mechanism provided by the invention is fully-sealed, small in size, good in durability, high in water-resistant pressure, and convenient to install.

Description

technical field [0001] The invention relates to a sealing device, in particular to a sealing device for an underwater deceleration drive mechanism. Background technique [0002] Oceans account for 71% of the earth's area and contain rich mineral resources, such as oil, natural gas, gas hydrate, polymetallic nodules, cobalt-rich nodule massive hydrothermal sulfide deposits, polymetallic ooze, barite, etc. With the decrease or depletion of land resources, the importance of marine resources has become more and more prominent, and people have begun to pay more attention to the investigation and development of marine mineral resources. [0003] In addition, as ocean development activities become more and more frequent and in-depth, human exploration and exploitation of offshore oil and gas, ocean surveys, ocean engineering, submarine pipelines, laying and maintenance of cables, and mining of marine minerals require the use of various resources. sample underwater equipment, and t...
