Abstract

The invention discloses a sinking and floating device for a small underwater vehicle, which is composed of a piston mechanism and a transmission mechanism. The open end of the drainage cylinder is fixedly connected to the U-shaped bracket. There are bracket middle horizontal plates on both sides of the U-shaped bracket. The left and right brackets are fixedly connected to the U-shaped bracket. The rack is fixedly connected to the cross plate. The lower parts on both sides form grooves with the horizontal plates of the cross plate. The cross plate and the two counterweight lead weights slide freely through the middle horizontal plate of the bracket respectively. The cross plate is fixedly connected with the rubber piston and is located in the suction and drainage cylinder. The motor of the transmission mechanism drives the driving gear and the four-stage driven double gear to rotate, and meshes with the rack. The rack drives the cross plate and the rubber piston to move. When the cross plate and the rubber piston move, the center of gravity of the aircraft is adjusted. When draining water and absorbing water, a force is generated to promote the attitude adjustment of the aircraft and realize the ups and downs of the aircraft.

Description

technical field [0001] The invention belongs to the technical field of small underwater vehicles, and in particular relates to a sinking device for low-speed small underwater vehicles. Background technique [0002] The way to realize the sinking and floating of the underwater vehicle includes increasing the gravity of the vehicle and tilting the attitude of the vehicle. The sinking and floating adjustment device includes a gravity adjustment device and a center of gravity adjustment device, which is an important part of the underwater vehicle's floating and sinking system. The sinking and floating adjustment device is installed inside the aircraft, and adjusts gravity and attitude by changing the mass of the aircraft and the attitude of the front and rear of the center of gravity of the aircraft or the attitude of the fin rudder to realize the diving or floating of the aircraft. Most of the existing sinking and floating adjustment devices are a single center of gravity or gr...
