On-board underwater target detection device

Abstract

The embodiment of the invention provides an on-board underwater target detection device, and relates to the technical field of underwater detection. According to the marine underwater target detection device, a signal transmitter is arranged at the top of a flow guide shell, a first motor is fixed to a battery compartment, a first bevel gear set is installed on the first motor, a driving rod is installed on the first bevel gear set, a propeller is fixed to a base, and a second bevel gear set is installed on the driving rod. The detection part is arranged in the flow guide shell, the stabilizing mechanism penetrates through the protection mechanism, the adjusting mechanism is arranged in the protection mechanism, an underwater target is detected through a detection assembly, diving and floating actions are completed through a first driving part, a signal is sent to a worker on a ship body through a signal transmitter, and then the worker on the ship body is driven to go through the stabilizing mechanism. The device is positioned and tracked, interference of the umbilical cable on the device in water is avoided, the device can dive to a deeper sea area, and the detection capacity of the device is improved.

Description

technical field [0001] The present application relates to the technical field of underwater detection, and in particular, to a device for detecting underwater targets on board. Background technique [0002] The ocean occupies about 70% of the earth's surface area, and the average water depth is about 3,800 meters. Such a huge ocean world contains abundant valuable resources that can be used by human beings, and it is the largest potential strategic base currently recognized by human beings. [0003] At present, when detecting underwater targets on the ocean, cabled underwater robots are mostly used for detection. However, in actual operation, the umbilical cable can indeed avoid the loss of the robot as much as possible, because the robot is recovered, but the umbilical cable also The diving depth of the robot is limited, and the depth of detection is limited. At the same time, due to the sloshing of sea water, the umbilical cable brings great interference to the robot, beca...

Problems solved by technology

[0003] At present, when detecting underwater targets on the ocean, cabled underwater robots are mostly used for detection. However, in actual operation, the umbilical cable can indeed avoid the loss of the robot as much as possible. The diving depth of the robot is limited, and the depth of detection is limited. At the same time, affected by seawater sloshing, the umbilical cable brings great interference to the robot, because one end of the umbilical cable is fixed on the hull and the other end is fixed on the robot. As a result, the umbilical cable is likely to swing the robot in the sloshing seawater, which will greatly interfere with the safety of the robot and the accuracy of detection.
