Floating piston type buoyancy regulator and use method

Abstract

The invention discloses a floating piston type buoyancy regulator and a using method, and relates to the field of buoyancy regulating equipment, and the floating piston type buoyancy regulator comprises a watertight pressure-resistant cabin, a regulating pipe and a hydraulic power system; a piston is arranged in the watertight pressure-resistant cabin in a sliding fit mode and divides the watertight pressure-resistant cabin into an inner liquid chamber and a pressure air chamber. A buoyancy adjusting medium is arranged in the inner liquid chamber, the inner liquid chamber is communicated outwards through an adjusting pipe, and the adjusting pipe is provided with a hydraulic power system. And the pressure air chamber is provided with a non-contact displacement sensor for detecting the displacement of the piston. The displacement of the piston can be detected in real time through the non-contact displacement sensor, then the buoyancy change is known, the measurement precision of the piston displacement is higher, the overall structure is simple, the use performance is more stable, the buoyancy adjusting medium is controlled in a closed space in combination with the expansion bag, and water pollution and corrosion are avoided. The overall buoyancy adjusting capacity is very good, and the buoyancy adjusting device can be suitable for buoyancy adjusting of different sizes.

Description

technical field [0001] The invention relates to the field of buoyancy adjustment equipment, in particular to a floating piston type buoyancy adjuster and a method of use. Background technique [0002] The existing buoyancy adjustment device can meet the general needs of buoyancy adjustment and control, but still has the following shortcomings: [0003] 1. The buoyancy adjustment control accuracy is not high, especially the repeatability accuracy is poor; [0004] 2. The structure is complex and the adjustment stability is poor; [0005] 3. Although the internal and external double-piston buoyancy regulator has high precision, it is not conducive to the flexible layout of the internal and external oil bladders, and the structure is limited; [0006] 4. The buoyancy adjustment is not flexible enough for the layout of the internal and external oil bladders; [0007] 5. The adjustment capacity of the mechanical transmission buoyancy regulator is too small to be suitable for l...
