Abstract
A device for observing the changes in abyssal flow based on differential pressure measurement, includes differential pressure sensing chamber and base connected through communicating portion, controller provided inside communicating portion, floating body and releasing device. Floating body is located on differential pressure sensing chamber and retracted through releasing device. Sensing chamber includes ambient water pressure chamber in communication with hydrostatic pressure chamber. Communicating portion is blocked by spring sheet. The spring sheet is provided with optical fiber sensor. Hydrostatic pressure chamber is always in communication with seawater, and ambient water pressure chamber is always in communication with water in abyssal sedimentary layer. Releasing device includes electric winch provided with acoustic signal device. Base is provided with earth pressure sensor and weight member. Optical fiber sensor, acoustic signal device, and earth pressure sensor are connected with controller. Differential pressure at a position can be measured by feedback from each sensor.
