Description

Technical Field

[0001] The utility model relates to the technical field of ocean exploration sonar detection, in particular to a side-scan sonar submersible carrying device. Background Art

[0002] Side-scan sonar can obtain a two-dimensional topographic map of the seabed on both sides of the route. It is mainly used to survey and map the seabed topography and can detect seabed reefs, shipwrecks and underwater obstacles. Traditional side-scan sonar generally works in a towed manner. The side-scan sonar and related circuits are installed in a towfish, which is connected to the survey ship with a cable. When the ship is sailing, the towfish is towed in the seawater at the stern of the ship. The ultrasonic side-scan sonar emits sound pulses to both sides in a fan-shaped beam. The receiving side-scan sonar receives the scattered echoes from the seabed and converts them into electrical signals. As the towfish sails forward, a continuous seabed topography map on both sides of the route is obtained.

[0003] There is a small-scale side-scan sonar submersible device with patent number 201820425915.0, which mainly includes a submersible body, a driving device, a side-scan sonar, a communication buoy and a land control end. The main body of the submersible is in the shape of a swimming fish, with water tanks on both sides; the driving device includes a propeller located at the tail of the submersible body and four thrusters located at the bottom of the submersible body; the side-scan sonar is fixed between two brackets below the submersible body; a radio transceiver and a GPS positioning device are installed on the communication buoy; the land control end communicates with the control center and the data collector through wireless transmission, sends operating instructions to the submersible and receives real-time detection data of the side-scan sonar and real-time parameters of the submersible. The utility model fixes the side-scan sonar directly below the main body of the submersible, which can reduce the impact of the offset and ups and downs caused by dragging and surface wind and waves on the collection results, and at the same time, there is no need to rent a ship, reducing the detection cost.

[0004] However, the above patent has the problem of inconvenience in adjusting the angle of the side-scan sonar after improvement, and the side-scan sonar is fixed to the body of the marine vehicle by bolts, which makes it inconvenient to disassemble and replace it, and it is inconvenient to use. Therefore, we propose a side-scan sonar submarine carrying device. Utility Model Content
