Underwater detection device and control method thereof

An underwater detection device, comprising a surface drive boat and an unmanned underwater vehicle for detecting an underwater structure, wherein the surface drive boat comprises:

• a hull;
• transverse attitude-stabilizing thrusters and orbit vectored thrusters arranged at bottom of the hull, the transverse attitude-stabilizing thrusters being configured to keep the hull stable, the orbit vectored thrusters being configured to adjust an attitude of the hull and drive the hull to move forward;
• a control box arranged on the hull and electrically connected with the transverse attitude-stabilizing thrusters and the orbit vectored thrusters;
• a cable and a cable winding assembly arranged on the hull, the control box being connected with the unmanned underwater vehicle by the cable, the cable winding assembly being electrically connected with the control box, the cable winding assembly being configured to adjust a telescopic length of the cable;
• and
• a positioning assembly arranged on the hull, electrically connected with the control box and configured to position the hull, wherein
• the hull comprises floating plates and a deck;
• the floating plates are fixed on a lower surface of the deck;
• the control box, the cable, the cable winding assembly, and the positioning assembly are all arranged on the deck;
• and the transverse attitude-stabilizing thrusters and the orbit vectored thrusters are arranged at bottoms of the floating plates.
