Problems solved by technology

Now the releaser is mostly shallow water type, and the deep sea water pressure is too high, which will cause the releaser shell to be too thick, and at the same time, the large internal and external pressure difference may cause the sealing ring to fail

Abstract

The invention discloses a piston type deep sea acoustic release device based on pressure compensation. The acoustic release device includes a release assembly, a pin assembly and a piston assembly, wherein the release assembly includes a first-level lever, a second-level lever, a release support plate and a pin shaft, the pin assembly includes a release device casing, a top cover, a support rod, aconnection pin, a lead screw nut, a lead screw, a coupling, a motor mounting seat, a driving motor and a rear cover, the piston assembly includes a piston and a sealing ring, and the release supportplate and the release device casing are mounted on the top cover through screws. The release device is advantaged in that an internal cavity of the release device casing is filled with hydraulic oil,the piston assembly can slide back and forth to make the hydraulic oil pressure in the release device casing substantially equal to the seawater pressure, the internal and external pressure differenceof the sealing ring is greatly reduced, reliability of the sealing ring is improved, automatic compensation for the deep sea pressure is achieved, moreover, thickness of the release device casing canbe greatly reduced by means of internal oil filling.

Description

technical field [0001] The invention belongs to the field of marine mechanical equipment, in particular to a piston-type deep-sea acoustic releaser based on pressure compensation. Background technique [0002] With the deepening of people's development and utilization of marine biological resources, seabed mineral resources and marine energy, the number of seabed environmental monitoring instruments and engineering application instruments that people put on the seabed is gradually increasing. As an auxiliary recovery tool for underwater equipment, it plays an irreplaceable role in marine survey and submarine engineering. The underwater acoustic response releaser is mainly used for the automatic recovery of underwater equipment. The underwater acoustic response releaser is a marine instrument and equipment that uses the principle of acoustic communication, integrates the acoustic response function and the underwater load release function, and indicates the position, release, ...
