Abstract

The utility model relates to an emergency floating device for an underwater robot, which relates to the field of marine technical equipment. The invention solves the problem that the existing underwater robot has a small volume, and the function feasibility of the floating device requires the assistance of other devices, which leads to the increase of the underwater robot's own gravity and the decrease of the floating speed. The watertight chemical reaction chamber, the pressurized power battery pack and the elastic shell hatch of the present invention are arranged from top to bottom on the center of gravity line of the underwater robot, and the two guides are arranged vertically opposite to each other on both sides of the watertight chemical reaction chamber. The two sides of the chemical reaction chamber are respectively connected with two guides. The gas separator is wrapped with ammonium dichromate and placed inside the watertight chemical reaction chamber. The airbag is embedded on the top of the watertight chemical reaction chamber. The bottom of the airbag is connected to the gas separator through an inflatable tube. , the inflation tube is provided with an inflation valve. The invention is used to optimize the ratio of the functionality of the internal device of the underwater robot to the occupied volume, and increase the net buoyancy of the underwater robot.

Description

technical field [0001] The invention relates to the field of marine technical equipment, in particular to an emergency floating device for an underwater robot. Background technique [0002] Due to the unknown and complexity of the underwater environment, the underwater robot will face various failures of incapacity, so that emergency floating means should be adopted to avoid more serious consequences. The current floating means are mainly divided into two aspects: (1) reducing the gravity of the underwater robot itself. Such as discarding disposable ballast, removing the ballast water in the ballast water tank: (2) increasing the displacement volume of the underwater robot to increase the buoyancy. Such as deploying air bags or oil bags in underwater robots. And these two kinds of devices all need other devices to guarantee the feasibility of its function, and this has just increased difficulty to the narrow and small underwater robot of volume originally. In addition, in...
