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.
