Problems solved by technology

However, in some special cases, such as after the underwater sampling robot collects samples, or when the gravity of the welding robot changes due to the consumption of welding wire, since most of the existing underwater buoyancy driving devices do not have an automatic buoyancy control device, they cannot adjust themselves. The remaining buoyancy of the underwater buoyancy driving device makes the underwater buoyancy driving device unable to complete the work stably

Abstract

The invention relates to an underwater buoyancy automatic adjustment device and a use method thereof, which solves the technical problems that the prior art underwater buoyancy driving device cannot automatically control and adjust its own buoyancy underwater and has high energy consumption for operation. The invention provides an underwater buoyancy automatic adjustment device, which includes a main controller, a hydropneumatic energy storage system respectively connected to the main controller, a two-way oil well pump and a first pressure sensor for detecting external environmental pressure; the hydropneumatic energy storage system The system includes an inflatable accumulator and a high-pressure gas cylinder. The inflatable accumulator includes a retractable airbag chamber and an oil chamber. The high-pressure gas cylinder is connected to the open end of the airbag chamber through the first pipeline; the front port of the bidirectional oil well pump passes through The second pipeline is connected with the open end of the oil chamber; the upper part of the elastic container is penetrated with an oil injection port, and the oil injection port is connected with the rear port of the two-way oil well pump through the pipeline; meanwhile, its usage method is also provided. The invention is widely used in the technical field of underwater buoyancy driving devices.

Description

technical field [0001] The invention relates to the technical field of underwater buoyancy driving devices, in particular to an underwater buoyancy automatic adjustment device and a method for using the same. Background technique [0002] Underwater buoyancy drive devices, such as autonomous underwater vehicles (Autonomous Underwater Vehicle) and buoyancy-driven underwater robots, have been widely used in scientific investigations, Marine operations, its application prospects are very broad. However, in some special cases, such as after the underwater sampling robot collects samples, or when the gravity of the welding robot changes due to the consumption of welding wire, because most of the existing underwater buoyancy driving devices are not designed with automatic buoyancy control devices, they cannot adjust themselves. The residual buoyancy of the underwater buoyancy driving device makes the underwater buoyancy driving device unable to complete the operation stably. Mor...
