Underwater sonar mine-sweeping detection system for unmanned ships

Abstract

The invention discloses an underwater sonar mine-sweeping detection system for an unmanned ship, and relates to the field of unmanned ship mine sweeping. The system comprises the unmanned ship which is provided with a supporting plate; a drive mechanism which is fixed on the supporting plate and comprises a motor and a worm and gear mechanism, wherein the motor drives the worm and gear mechanism to carry out the transmission, and the drive mechanism also comprises a protection cover which covers the motor and the worm and gear mechanism; a first rotating shaft which is disposed on the worm and gear mechanism, and is driven by the transmission of the worm and gear mechanism to rotate, wherein two ends of the first rotating shaft respectively pass through the supporting plate and the protection cover; a supporting rod which is fixed at one end, passing through the supporting plate, of the first rotating shaft; a sonar mine-sweeping detection device which comprises an energy transducer and a probe transmitter, wherein the energy transducer is fixed at one end of the supporting rod, and the probe transmitter is detachably fixed on the energy transducer, and a probe can be replaced automatically. According to the invention, the system is high in mine-sweeping detection accuracy, is low in installation and disassembly cost, and is low in maintenance cost.

Description

technical field [0001] The invention relates to the field of mine-sweeping unmanned ships, in particular to an underwater sonar mine-sweeping detection system for unmanned ships. Background technique [0002] An unmanned ship is an intelligent unmanned platform that can perform various civilian and military tasks in complex water environments such as the ocean. It is mainly used for detection and patrol, and can perform repetitive and highly repetitive tasks in harsh marine environments for a long time. The use of unmanned ships does not need to worry about the living space of personnel. It can reduce the ship's cabin capacity and load, reduce labor costs, improve operational accuracy through autonomous operations, and reduce the risk of personnel operating errors. At the same time, it can enable ships to carry more cargo or equipment. [0003] Because of its small size and good invisibility, unmanned ships have received attention and development from all over the world in ...

AI Technical Summary

Problems solved by technology

[0003] Because of its small size and good invisibility, unmanned ships have received attention and development from all over the world in recent years. Among them, the use of unmanned ship mine clearance has become the focus of application. Currently, the use of unmanned ship mine clearance is mainly achieved by sonar technology, but existing The sonar equipment is usually fixed on the bottom of the unmanned ship, and its rotation freedom is poor, which seriously affects the scanning and detection range of the sonar equipment, which in turn affects the detection accuracy of the sonar equipment. Not easy, overall low maintenance efficiency

In addition, sonar equipment generally transmits acoustic signals through probes, and the existing probe transmitters are generally fixed on the transducers of sonar equipment. Once the probe transmitters are damaged, the transducers of the entire sonar equipment need to be repaired. Repair costs are too high
