Amphibious underwater acoustic detection buoy

Abstract

The invention discloses an amphibious underwater acoustic detection buoy, and belongs to the field of marine exploration equipment. The amphibious underwater acoustic detection buoy comprises an unmanned aerial vehicle part, a floating and sinking control part and an underwater acoustic detection part; the unmanned aerial vehicle part comprises a propeller part and a flight control system; the flight control system realizes autonomous navigation through MEMS inertial navigation and GPS combined navigation, and controls an attitude of the amphibious underwater acoustic detection buoy in air; the flight control system of the unmanned aerial vehicle part, the floating and sinking control part and the underwater acoustic detection part are mounted in a first watertight cabin, a second watertight cabin and a third watertight cabin respectively; the three watertight cabins are subjected to waterproof and sealing treatment to ensure the waterproof and sealing performance; the floating and sinking control part is used for controlling the position of the amphibious underwater acoustic detection buoy in water through a buoyancy regulating device; the underwater acoustic detection part comprises a sonar and a power battery; the power battery is used for providing power for the sonar; and the sonar is used for underwater acoustic detection. The amphibious detection buoy is long in workingtime, small in size, convenient to recycle and capable of realizing single-point throwing and multi-point measurement.

Description

Technical field [0001] The invention belongs to the field of marine exploration equipment, and specifically relates to an amphibious underwater acoustic detection buoy. Background technique [0002] Currently, unmanned exploration of the marine environment mainly adopts two methods: marine buoys and AUVs. [0003] Among the marine buoys, the profile buoy is represented by adjusting its buoyancy to achieve underwater vertical reciprocating motion. A typical example is the HM2000 profile buoy produced in my country. There are PALACE, APEX, PROVOR, SOLO and other models abroad. However, the profile buoy is suitable for deep-sea exploration with a detection depth of several kilometers, and it can only be launched and measured at a single point, and has the disadvantage of inconvenient recovery. [0004] The cableless underwater robot AUV is the main method of ocean survey at present, such as the CR series and the "Qianlong" series developed by my country's Shenyang Institute of Automat...

Problems solved by technology

In addition, although the buoy can perform multiple dives and surfacing detections after it is launched, the position of each detection depends entirely on the direction of the ocean current.

If multi-point detection with precise locations is required, it must be manually recovered after each detection and placed again, which is inconvenient to use
