Problems solved by technology

It is worth noting that the longer the pressure chamber, the worse its sealing reliability
And the battery pack slides inside the pressure chamber, there will be an offside phenomenon, and the battery pack slider may touch the sealing cover, causing the seal to fail

Abstract

The invention discloses a gravity center adjustment device for an underwater submersible vehicle. The gravity center adjustment device for the underwater submersible vehicle comprises a sliding frame,a pressure proof cabin and a driving device. The pressure proof cabin is slidably connected to the sliding frame, and the driving device drives the pressure proof cabin to slide on the sliding frameand locks a position of the pressure proof cabin on the sliding frame. By integrally moving the pressure proof cabin, the moving quality of is large, the pressure proof cabin is not limited by internal space of the pressure proof cabin, the gravity center is changed and displacement is larger, the effect is obvious, internal collision of the pressure proof cabin cannot be caused, devices and a pressure proof cabin cover cannot be damaged, more reliability and safety are achieved, the structure is simple, and the problem of disabled invalid sealing of the pressure proof cabin due to the fact that an existing gravity center adjustment device needs to increase pressure proof cabin space during adjusting a battery pack in the pressure proof cabin and is prone to ejecting a sealing cover is solved.

Description

technical field [0001] The invention generally relates to the field of underwater vehicles, in particular to a center-of-gravity adjustment device for an underwater underwater vehicle. Background technique [0002] Underwater vehicles need to float and dive during navigation. Generally, a vertical thruster is added to realize this action, and the direction of thrust is changed through positive and negative rotation to achieve ascent and dive; however, setting too many thrusters will increase the Power consumption. By adding a device to adjust the center of gravity, changing the internal mass distribution of the submersible, resulting in a top-heavy attitude or a top-heavy attitude, it is possible to make the submersible sink or rush upward without additional propellers. [0003] There are many similar mechanisms on underwater gliders, but they all use screw drive, and the position of the center of gravity is changed by moving the battery pack inside the pressure-resistant c...
