Buoyancy adjusting device with emergency floating function and buoyancy adjusting method thereof

Abstract

The invention discloses a buoyancy adjusting device with an emergency floating function and a buoyancy adjusting method of the buoyancy adjusting device. A sliding guide rail is fixed to the bottom of a sealed cabin, and the sliding guide rail and the n sliding blocks form a sliding pair. The end part fixed plate is fixed on the sliding guide rail; the end part movable plate and the (n-1) movable frames are fixed with the n sliding blocks one by one; the adjacent movable frames, the end fixing plates and the adjacent movable frames, and the end movable plates and the adjacent movable frames are fixedly connected through telescopic rod sets. One end of an inner oil bag is fixed with the end fixed plate, and the other end is fixed with the end movable plate; and the pipeline is communicated with the inner oil bag and the outer oil bag. Each shrinkage rod of a shrinkage rod group is made of an electroactive polymer material. Buoyancy adjustment is achieved only through the telescopic rod, the response time is short, and energy does not need to be consumed in the rising process; only one pipeline is needed for oil transmission, so that the reliability is high; the emergency quick floating function is achieved; and when a controller also breaks down, the controller can still float naturally after power consumption is finished.

Description

technical field [0001] The invention belongs to the technical field of underwater vehicles, and in particular relates to a buoyancy regulating device with an emergency floating function and a buoyancy regulating method thereof. Background technique [0002] The ocean occupies 70% of the earth's surface area and contains abundant natural resources. As an important tool for underwater operations, underwater vehicles have been widely used in ocean research and ocean exploration. Underwater vehicles need to operate in waters of different depths, so energy-saving and accurate buoyancy adjustment devices are crucial for underwater vehicles. [0003] Existing buoyancy adjustment devices mainly contain volumetric type and gravity type. The gravity type mainly adjusts the buoyancy by changing its own weight when the volume remains unchanged. A typical example is the dumping buoyancy adjustment mechanism. Since the dumping action is one-time, it is generally used for emergency or au...

AI Technical Summary

Problems solved by technology

Conventional emergency flotation systems usually adopt external control or self-controlled mechanical dumping, but once the control system fails, it is easy to cause the failure of dumping, which will lead to the permanent loss of underwater vehicles, which will bring great harm to the country and society. big economic loss
