Safely detachable beidou beacon floating body with small size and light weight

Abstract

The invention relates to a safely detachable beidou beacon floating body with a small size and a light weight, and belongs to the field of underwater vehicle water surface positioning. At present, theunderwater vehicle is developed towards the trend of miniaturization and light weight, in addition, the function required to be realized is increased, and the packing density is larger and larger; the installation space of the beidou beacon floating body becomes smaller and smaller, and a high problem is brought to the design of the beidou beacon floating body. Therefore, a beidou antenna is assembled on a floating bag, and a structure function part of a traditional beidou beacon is not needed, and therefore the size is obviously reduced. The radial layout of a traditional beidou beacon floating body in an underwater vehicle is broken through, and instead, an axial layout is adopted, so that the narrow and small space of the small lightweight underwater vehicle can be better utilized, andthe floating body can be safely separated from the underwater vehicle for floating on the water surface in a stable state in order to indicate the position of the underwater vehicle. The safely detachable beidou beacon floating body can be used for the accurate positioning of the long-distance position during the recovery of the marine test task by the underwater vehicle.

Description

technical field [0001] The invention belongs to the field of water surface positioning of underwater vehicles, in particular to a Beidou beacon buoy with small volume, light weight and safe separation. Background technique [0002] When the underwater vehicle completes the sea test task and needs to be recovered, due to the complex sea test conditions, the visual search distance is short, and it is greatly affected by the weather and sea conditions, the beacon machine is generally used for positioning. The Beidou beacon uses my country's Beidou satellite positioning technology, which can Realize the precise positioning of the long-distance location and realize the purpose of recycling. At present, underwater vehicles are developing towards the trend of miniaturization and light weight. At the same time, the functions that need to be realized are increasing, and the segment density is increasing. The traditional Beidou beacon buoys cannot be arranged in it due to their large v...

AI Technical Summary

Problems solved by technology

The difficulty in realizing the axial layout is that the relationship between the inflation volume of the gas cylinder and the volume of the floating bag must be properly handled. If the inflation volume is too small, the impact force will be too small. The working pressure of the floating bag causes the floating bag to rupture and cannot hold the antenna

In addition, the attitude of the remaining part of the underwater vehicle after the head section shell is separated will affect the attitude of the small Beidou floating body
