Gravity type intelligent acoustic monitoring buoy

A gravity type intelligent acoustic monitoring buoy comprises a buoy box body and a buoyancy base, the upper surface of the buoyancy base is fixedly connected with the buoy box body, and the lower surface of the buoyancy base is connected with a sonar through a flexible connecting piece; a radar is arranged outside the buoy box body, and a control system is arranged inside the buoy box body so as to receive, process and transmit signals of the radar and the sonar. According to the utility model, ships and objects in the surrounding sea area are scanned by the radar, and the underwater environment is scanned by the sonar, so that more comprehensive and accurate monitoring information can be provided for the monitored sea area, and the position and motion trail of the marine environment, a submersible and other marine equipment can be remotely monitored in real time; meanwhile, the buoy is pulled through the dead weight of the sonar, instability of the buoy caused by the influence of water flow and tide is avoi
