Emergency buoy of AUV (Autonomous Underwater Vehicle)

Abstract

The invention discloses an emergency buoy of an AUV (Autonomous Underwater Vehicle), which is simple in structure, smaller in size and applicable to a deeper water area, when the AUV is in danger underwater and cannot float upwards, the buoy automatically floats upwards, and the AUV and the buoy share a real-time position, so that personnel can conveniently salvage and search and rescue. The buoy is composed of a buoy water cabin, a buoy underwater cabin and buoyancy materials, and power systems of all the parts are independent and provide energy for a control module and electronic equipment of the buoy water cabin, the buoy underwater cabin and the buoyancy materials respectively. The buoy underwater cabin is connected with the AUV through a modular interface, the buoy water cabin is connected with the buoy underwater cabin through a strong electromagnet, when the AUV is in danger, the electromagnet is powered off, the buoy water floats to the water surface through positive buoyancy of a buoyancy material, and meanwhile, the buoy underwater cabin shares position information of the AUV with the buoy water cabin in real time; and the buoy water cabin sends the position information of the buoy water cabin and the position information of the AUV to a worker upper computer.

Description

technical field [0001] The invention relates to the technical field of underwater robots, in particular to an AUV emergency buoy. Background technique [0002] With the increasing number of marine research and exploration activities, the field of underwater robot technology has also received increasing attention from researchers at home and abroad. In recent years, AUV (Unmanned Submersible Vehicle) has been widely used in seabed resource exploration, seabed topographic mapping, and seabed archaeology. Wait. However, the loss of AUV will bring huge economic losses to users.

However, the loss of AUV will bring huge economic losses to the users

[0003] Some of the existing AUVs are equipped with emergency search and rescue devices, that is, the AUV automatically releases a buoy with a tether cable when it is in distress, and lifts the AUV out of the water through the tether cable; but this emergency device takes up a lot of space, and the tether cable is easy to get stuck In the crevices of the reef, the buoy cannot be floated up, so that the staff cannot know the specific position of the AUV. In addition, due to the limited length of the tether, this kind of buoy with a tether is not suitable for deep waters
