Deep-sea oil-pocket buoyancy regulation device

Abstract

The invention provides a deep-sea oil-pocket buoyancy regulation device, comprising a control cabinet, a pressure-resistant oil tank and a telescopic oil pocket. The buoyancy regulation device is characterized in that the upper hemispheroid and the lower hemispheroid of the control cabinet are connected with each other; a mounting plate is fixed in the lower hemispheroid; a DC motor, a motor driver, a hydraulic pump and a control circuit board are arranged on the mounting plate; the lower hemispheroid is provided with an oil inlet and an oil outlet; the pressure-resistant oil tank comprises a left hemispheroid, a cylindrical barrel and a right hemispheroid, and the two sides of the cylindrical barrel are respectively connected with the left hemispheroid and the right hemispheroid; the telescopic oil pocket comprises an upper end cover, a lower end cover, an outer sleeve, an oil filter and a displacement-type liquid level sensor; the outer sleeve is respectively connected with the upper end cover and the lower end cover; the oil filter is fixed on the lower end cover; the displacement-type liquid level sensor is arranged on the oil filter; and the oil inlet of the control cabinet is connected with the telescopic oil pocket, and the oil outlet of the control cabinet is connected with the pressure-resistant oil tank. The deep-sea oil-pocket buoyancy regulation device of the invention measures the liquid level of the hydraulic oil in the pressure-resistant oil tank by utilizing the ball float-type liquid level sensor, thus having higher measuring precision and no accumulated error.

Description

technical field [0001] The invention relates to a buoyancy device, in particular to a buoyancy adjustment device for realizing the heave motion, depth control and attitude adjustment of an underwater robot or other underwater devices. Background technique [0002] Since the energy carried by the cableless underwater robot is limited when heading, in order to reduce the energy consumption of the underwater robot as much as possible and realize the submerged and carrying functions of the underwater robot, it is very necessary to equip it with a buoyancy adjustment device. The underwater robot buoyancy adjustment device can realize the diving, floating, suspension, fixed-depth navigation and attitude adjustment of the underwater robot, which is important for the underwater robot with a long voyage and a large diving depth. [0003] It is easy to realize the buoyancy adjustment of the underwater robot by discarding the ballast, but the ballast must be reinstalled before each lau...

Problems solved by technology

[0003] It is easy to realize the buoyancy adjustment of the underwater robot by discarding the ballast, but the ballast must be reinstalled before each launch, and the buoyancy adjustment during a heading is not repeatable; use seawater pumps to pump water into the ballast tank The way of drainage has strong buoyancy adjustment ability, simple form, stable performance, safety and environmental protection, and can be reciprocally adjusted to provide positive and negative buoyancy. However, seawater is highly corrosive, low viscosity, and poor lubricity, which leads to
