Disposable ballast protection device for manned submersible

Abstract

A droppable ballast protection device for a manned submersible comprises a manned cabin. A stepping motor with double output shafts is mounted in the manned cabin through a motor supporting seat, the upper output shaft penetrates a through hole of a mounting platform and then is connected with an inner hole of an electromagnetic clutch in a matched manner, the lower output shaft is connected with a spindle through a slider coupling, the spindle penetrates a manned cabin wall, a penetrating portion is sealed by a stuffing box sealing device, a supporting plate sleeves the lower end of the spindle through a nut and is positioned below a droppable ballast, the left end of the supporting plate is fitted with a hull structure T-shaped profile, the bottom of the manned cabin wall is connected with a sleeve mounting seat through screws and provided with two permeable holes, the bottom of the sleeve mounting seat is connected with a liquid level sensor, a waterproof connector is connected onto the manned cabin wall in a threaded manner, a control box is mounted on the manned cabin wall, a signal line of the liquid level sensor is connected with the control box through the waterproof connector, and the stepping motor with the double output shafts and a tail line of the electromagnetic clutch are respectively connected onto the control box. The droppable ballast protection device is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of manned submersibles, in particular to a disposable ballast protection device for deep-sea manned submersibles, and is a safety protection device for manned submersibles. Background technique [0002] Manned submersibles carry scientists and engineers into the deep sea to effectively perform marine scientific investigations and other related underwater operations. In order to improve the safety of manned submersibles working in the deep sea, especially the life safety of divers, emergency disposable ballast devices are usually arranged outside the pressure hull of manned submersibles. When underwater equipment fails, manned diving will be endangered. When the safety of the submersible and the safety of the submersible, the submersible will trigger the electric switch, hydraulic switch or manual switch in the manned cabin to throw away the discardable ballast, so that the manned submersible is in a positive...

AI Technical Summary

Problems solved by technology

During the equipment maintenance process of the manned submersible on the surface mother ship, due to time constraints, usually the technicians of each system are carried out at the same time, and the equipment inside the manned cabin and the equipment outside the manned cabin are maintained at the same time. In this case, it is very difficult It is easy for other professionals to mistakenly touch the electric, hydraulic or manual switch of the discardable ballast, causing hundreds of kilograms or even several tons of discardable ballast to be separated from the manned submersible, which is very easy to injure the manned submersible Bottom maintenance personnel, causing irreparable safety accidents

In addition, in the process of lifting and deploying the manned submersible, since the submersible usually only has 1-2 lifting points, the submersible will shake violently. The touch switch of the discarded ballast will cause the discarded ballast to fall off, causing a safety accident
