Abstract

The invention discloses a portable ultra-short baseline fixing device and a fixing method, comprising: a retractable rod located on one side of a hull, the retractable rod is rotatably matched with the hull; an ultra-short baseline body, the ultra-short baseline body and the retractable rod The top end is connected and fixed; it also includes a propulsion assembly, which is used to cooperate with the retractable rod to enter the seawater; a rotating assembly, which is used for fixing the propulsion assembly; and a second fixing assembly, which is used for fixing The retractable rod into the sea, through the action of the water flow during the driving process, drives the rotating rod to rotate downward through the pressing plate, and the clamping groove is blocked by the pressure plate and the limit groove, so as to reduce the impact force on the rotating rod, thereby reducing the rotation of the rotating rod. The force of the support point prevents the shaft of the rotating rod from being easily damaged.

Description

technical field

[0001] The invention relates to the technical field of ultra-short baseline, in particular to a portable ultra-short baseline fixing device and a fixing method. Background technique

[0002] USBL (ultra-short baseline) is an underwater positioning technology, which is currently widely used in offshore oil exploration and development, marine salvage and other marine production and development. It is mainly used to determine the underwater accuracy of ROV, ads, divers, and other underwater carriers. Location.

[0003] The ultra-short baseline positioning system consists of a transmitting transducer, a transponder, and a receiving array. The transmitting transducer and receiving matrix are installed on the ship, and the transponder is fixed on the underwater carrier. The transmitting transducer sends out a sound pulse, and the transponder sends back a sound pulse after receiving it. After receiving it, the receiving base array measures the phase difference in ...
