Universal top-mounted fuse type deep-sea single-chamber instrument recovery decoupling device

Abstract

The invention discloses a universal and external-overhead fusing type deep-sea single-cabin instrument retrieving and unhooking device. The device is characterized in that support seats (9) are fixed on the lower sides of two symmetrical ends of a polar plate (6) respectively, an ejection plate (10) is fixed at the bottom of each support seat (9), a rotating shaft (8) is mounted at the upper part of the outer side of each support seat (9), the rotating shafts (8) on two sides are parallel to each other, steel wire hooks (7) are arranged at two ends of each rotating shaft (8) respectively, and the middle of each rotating shaft (8) is connected with a wire winding rod (13). An external mounting mode is adopted, a releasing structure is located at the top of a main cabin and not affected by the structure of the main cabin, and offshore operation is facilitated. The universality of an unhooking mechanism is improved, the application range of the unhooking mechanism is broadened, and the development cost is reduced; the main cabin is fixed by four points and well coupled with a sinking coupling frame, and relative torsion of the cabin and the sinking coupling frame is prevented effectively. The transmission ratio reaches 20:1, load of the unhooking mechanism is reduced effectively, the structure is fine and compact, and the releasing and retrieving success rates are increased.

Description

technical field [0001] The invention belongs to the technical field of IPC classification B63C marine exploration equipment. It is an equipment used for underwater operations or a device used for salvaging or searching underwater targets, and relates to a bottom release device of a marine observation instrument, especially a general-purpose external top-mounted fuse type. Decoupling device for recovery of deep-sea single-chamber instrument. Background technique [0002] It is an internationally advanced long-term ocean observation technology to observe with an anchored submersible buoy on the seabed, which can realize full-section ocean current observation and long-term observation of various ocean physical quantity elements, making up for the shortcomings of ocean short-term observation and navigation observation . China's fourth Arctic scientific expedition team successfully recovered a submarine anchored at the bottom of the Arctic Ocean at a depth of more than 1,600 met...

AI Technical Summary

Problems solved by technology

Existing release and recovery systems have a variety of structures, but limited to the complex structure and heavy weight of the observation instrument, the load of the release system is large, and it is not easy to release quickly, resulting in a decrease in the recovery rate of the observation instrument
