Problems solved by technology

Although the water hydraulic technology is compatible with the marine environment, has the advantages of automatic compensation of sea depth pressure, low operating cost, and easy handling of the working medium, it requires multiple additional solenoid valves and one-way seawater pumps to complete the system's submersion and surfacing. , not only the system structure is complex, but also there are problems such as high pump working pressure, unused deep sea pressure energy, and large shell pressure

Embodiment 1

[0026] Example 1, such as Figure 4 As shown, this embodiment discloses an oil-hydraulic buoyancy adjustment system. The system includes a housing 41 filled with an inert gas of a certain pressure; an outer container 42 containing hydraulic oil is arranged outside the housing 41 The housing 41 is provided with an inner container 43 containing hydraulic oil, a two-position two-way electromagnetic reversing valve 44 and a two-way hydraulic pump-motor 45. The volume of the outer container 42 and inner container 43 can be changed with the change of the internal hydraulic oil. The elastic oil bag, and the inner container 43 and the outer container 42 are connected through the above-mentioned two-position two-way electromagnetic reversing valve 44 and the two-way hydraulic pump-motor 45 so as to transmit hydraulic oil between each other; the housing 41 A motor-generator 46 connected to the two-way hydraulic pump-motor 45 is also provided, a control system 47 for controlling the work...

Abstract

The invention discloses an oil hydraulic buoyancy adjusting system. The system comprises a shell; the shell is filled with gas with a certain pressure; an outer container for holding hydraulic oil is arranged out of the shell; an inner container for holding the hydraulic oil, a two-position two-way electromagnetic directional valve and a two-way hydraulic pump-motor are arranged in the shell; the inner container and the outer container are connected through the two-position two-way electromagnetic directional valve and the two-way hydraulic pump-motor for mutual hydraulic oil transfer; and a motor-generator connected with the two-way hydraulic pump-motor, a control system for controlling the motor-generator to work and a rechargeable power supply for storing electric energy generated by the motor-generator and supplying electricity to all devices in the shell are also arranged in the shell. The oil hydraulic buoyancy adjusting system and method, disclosed by the invention, realize the diving and floating control of such underwater operation equipment as underwater robots through changing the volume of the outer container and adjusting the buoyancy.

Description
