Embodiment Construction

[0022] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] like figure 1 , Figure 4 As shown, the novel submersible used for long-distance acousto-optic two-way guidance to capture and recover AUV in this embodiment is connected with the winch 10 through the umbilical cable 14, and the winch 10 is arranged in the underwater mother ship platform 15, and the mother ship platform 15 The submersible can be released by opening the door; the submersible includes a supporting frame 1, and the supporting frame 1 is used as a carrier for supporting and installing the submersible equipment, and plays a role in protecting the equipment on the submersible. Support frame 1 has the sleeve cavity that can accommodate AUV11, and buoyancy block 5 is installed in support frame 1 (see figure 2 , image 3 ), horizontal thruster 2, vertical thruster 3, fixed clamping mechanism 9 (see image 3 ) and the acou...

Abstract

The invention relates to a novel submersible for capturing and recovering AUV through long-distance acousto-optic bidirectional guidance. The submersible is connected with a winch through a umbilical cable and comprises a supporting frame, and an acoustic receiving and transmitting transducer is installed on the supporting frame; an acoustic transponder in butt joint with the acoustic receiving and transmitting transducer is arranged at the end of the AUV; an optical generator is installed in the supporting frame, and an optical receiver in butt joint with the optical generator is installed at the end of the AUV. According to feedback signals of the optical generator and the acoustic receiving and transmitting transducer, the own forward direction of the submersible is corrected, and the own forward direction of the AUV is corrected so that the AUV can be in butt joint with the submersible. The submersible can get away from a mother ship to actively capture the AUV, acousto-optic bidirectional guidance of the submersible and the AUV is adopted for butt joint, the butt joint positioning distance and accuracy of butt joint recovery can be improved, the long-distance butt joint guidance capacity is improved, and the AUV can be recovered and released in the mode of being away from the mother ship.

Description

technical field [0001] The invention relates to the technical field of submersibles, in particular to a submersible and a new method for accurately capturing, recovering and deploying an AUV underwater. Background technique [0002] The underwater recovery of AUV (untethered underwater robot) has always been a hot and difficult research issue. At present, the main methods of AUV recovery are: autonomous recovery through the funnel-type recovery device fixed on the mother ship or the bottom platform of the mother ship; through the camera of ROV Observation of the instrument, the recovery of the AUV from the submarine torpedo tube by using the ROV manipulator to clamp the AUV, etc. Due to the influence of the mother ship's hydrodynamic force, noise or magnetic field, and the underwater mother ship is in a relatively complicated navigation and operation state during the docking process, the docking accuracy is low and the recovery rate is not high.
