[0039] Example

[0040] A buoyancy-adjusting plunger pump device used in deep-sea deep submersibles. The buoyancy-adjusting plunger pump can be driven by the reciprocating motion driven by a motor, an oil motor or an oil cylinder, so as to adjust the ballast in the submersible The atmospheric seawater in the tank is discharged into the working depth of the submersible to achieve the purpose of adjusting the buoyancy of the submersible. The device mainly includes an input valve group, an output valve group, a reciprocating drive piston mechanism and a pressure-resistant cylinder. The pressure-resistant cylinder includes an input insertion hole, an output insertion hole and a drive insertion hole. The input insertion hole and the output insertion hole are on an axis, and the drive insertion hole intersects the axis vertically to form a T Type of channel. The input valve group is installed in the input insertion hole of the pressure-resistant cylinder block and fixed by screwing, ...

Abstract

The invention discloses a buoyancy adjusting plunger pump device for a full-sea-depth submersible. The buoyancy adjusting plunger pump device comprises an input valve set, an output valve set, a compression-resistant cylinder body and a reciprocating driving piston mechanism. The compression-resistant cylinder body comprises an input insert-mounting hole, an output insert-mounting hole and a driving insert-mounting hole; the input insert-mounting hole and the output insert-mounting hole are located on the same axis, and the driving insert-mounting hole and the axis intersect vertically to forma T-shaped channel; inner threads are arranged in the three insert-mounting holes correspondingly; and the input valve set, the output valve set and the reciprocating driving piston mechanism are located in the input insert-mounting hole, the output insert-mounting hole and the driving insert-mounting hole of the compression-resistant cylinder body correspondingly and all fixed through the threads. The buoyancy adjusting plunger pump device can work at the full sea depth, a main movement structure bears external huge seawater pressure through a pressure-bearing part, reliable working of a system can be ensured, the device is simple, and the mechanical efficiency and volume efficiency are high.

Description

technical field [0001] The invention belongs to the technical field of submersibles, and relates to a buoyancy adjustment device, in particular to a buoyancy adjustment plunger pump device for deep-sea submersibles. Background technique [0002] With the continuous development of science and technology, human beings explore the ocean more and more deeply, often requiring the use of large-depth submersibles. For now, large-depth submersibles, especially large-depth untethered manned submersibles and unmanned submersibles, all need a buoyancy adjustment system to adjust the buoyancy of the submersible during underwater movement, so as to adjust whether the submersible floats or Dive down to compensate for buoyancy changes caused by changes in the external environment. Using seawater to adjust the buoyancy state of the submersible is a very simple and practical way, but the buoyancy adjustment of the full-sea deep submersible is faced with the impact of the pump body being aff...
