Abstract

The invention provides a self-position-guard sonar positioning buoy and belongs to the technical field of underwater sound communication and dynamic positioning. The self-position-guard sonar positioning buoy solves the problems that an existing underwater sound positioning buoy is poor in reliability and likely to be affected by wind and waves to deviate from a target point, a posture is difficult to keep, and arrangement and recovery are complex. A floating body is arranged on the outer side of an underwater sound transducer electronic cabin of the self-position-guard sonar positioning buoy. Shells comprise the two wing-shaped structure shells with different chord lengths. The two wing-shaped structure shells are coaxially connected. The underwater sound transducer electronic cabin, the floating body and a steering engine are all arranged in the wing-shaped structure shell with the large chord length, the floating body is arranged on the outer side of the underwater sound transducer electronic cabin, the steering engine is arranged on the upper side of the floating body and drives a rudder plate to swing, the rudder plate is arranged on the rear side of the wing-shaped structure shell with the large chord length, stabilizers are symmetrically arranged on the left side and the right side of the wing-shaped structure shell with the large chord length, and main propellers are arranged on the lower sides of the two stabilizers. The self-position-guard sonar positioning buoy is suitable for being used as a buoy.

Description

technical field [0001] The invention belongs to the technical field of underwater acoustic communication and dynamic positioning. Background technique [0002] At this stage, the underwater target positioning and tracking technology mainly uses the geometric principle of underwater acoustic positioning method. The buoy array is designed according to a certain formation, and the acoustic signal of the target is collected through the underwater acoustic transducer that is suspended, and then the data information is transmitted by radio communication technology. The data is packaged and uploaded to the mother ship, and the computer on the mother ship unpacks and stores the received data, calculates the target position by using spherical intersection technology, and monitors the working status of the buoy array. However, restricted by many factors, the existing underwater acoustic positioning buoys have problems such as single function, poor reliability, easy to be affected by w...
