Problems solved by technology

[0004] (1) The driving mode is driven by a hydraulic station, and there is a situation that it cannot be started when the power is off;
[0005] (2) The transmission mechanism is mechanically pierced through the cabin, and there is a problem of dynamic sealing, which is not suitable for submersibles with large diving depths;
[0006] (3) The piston rod and the pin shaft are rigidly connected, which has a certain impact on the sealing performance of the hydraulic cylinder and the rigidity of the mechanism;
[0007] (4) As the diving depth increases, in order to ensure the relative fixation of the piston rod, the hydraulic cylinder needs to increase the pressure compensation to withstand the increasing water pressure, which will cause a certain burden on the hydraulic system

Abstract

Disclosed is a deep sea manual hydraulic driving type disposable ballasting device. The deep sea manual hydraulic driving type disposable ballasting device comprises a hydraulic driving mechanism, an operating mechanism and a ballast. The hydraulic driving mechanism is a manual hydraulic pump which is arranged in a cabin body of a deep sea manned submersible device. The operating mechanism is a hydraulic cylinder which is located at the exterior of the cabin body. The manual hydraulic pump is connected with an oil inlet opening of the hydraulic cylinder through a cabin-penetrating pipeline. A cabin body of the hydraulic cylinder is fixedly connected with the deep sea manned submersible device. A piston rod of the hydraulic cylinder is connected with a pin shaft through a universal joint. The universal joint comprises a ball head of the head part of the piston rod and a groove matched with the ball head on the pin shaft. The ballast is provided with a first lifting lug. The deep sea manned submersible device is fixedly connected with a second lifting lug. Lug holes of the first lifting lug and the second lifting lug are movably connected with the piston rod in a penetrated mode. The pin shaft is driven to be engaged or disengaged from the first lifting lug through axial moving of the piston rod. According to the deep sea manual hydraulic driving type disposable ballasting device, through direct manual control of operators in the cabin body of the deep sea manned submersible device, load rejection can be achieved, and the load rejection is reliable, stable and safe.

Description

technical field [0001] The invention relates to the technical field of underwater discardable ballast, in particular to a device for manned submersibles to manually dump loads, especially to a device that is applied to deep-sea manned submersibles in an emergency state, which can be realized by manual operation of the staff in the submersible Loading device. Background technique [0002] Disposable ballast device is an important system for submersible submersion and surfacing. In an emergency state, the disposable ballast can be quickly discarded, so that the submersible can generate a certain head-up moment and positive buoyancy, so as to achieve the purpose of self-rescue. There are many kinds of dumping driving methods for discardable ballast. At present, manual operation, hydraulic driving, electromagnetic induction, explosive bolt and their combined driving methods are widely used, and their structural forms are even more diverse. , There are hanging type, ring buckle ...
