Description

Technical Field

[0001] This invention belongs to the field of marine unmanned technology, specifically relating to an unmanned surface vessel and method for capturing autonomous underwater vehicles. Background Technology

[0002] For unmanned underwater vehicles (UUVs) and autonomous underwater vehicles (AUVs) of unknown origin, existing capture technologies, such as traditional manual diving salvage and conventional ship trawling, have significant drawbacks. Manual diving salvage is inefficient and highly dangerous, while conventional ship trawling can easily damage the target equipment, making both unsuitable for practical applications. While a solution based on unmanned surface vessels (USVs) equipped with high-precision detection equipment and dedicated capture devices, leveraging their autonomous navigation, remote control, and long endurance to achieve non-contact, precise capture of UUVs offers a new approach to UUV capture, existing AUV capture methods still face numerous technical challenges.

[0003] The first capture method is to use a USV equipped with a robotic arm for grasping. This method requires extremely high control precision of the robotic arm. At the same time, since the movement trajectory of the AUV underwater is unpredictable, the position of the USV needs to be adjusted in real time during the capture process, which also places stringent requirements on the control of the USV. Furthermore, this method is less applicable in deeper water environments.

[0004] The second method of capture is trawling. However, the process of trawling in the water is complicated and cumbersome, and the fishing process is difficult to control effectively. It is only suitable for capturing AUVs with low speed.

[0005] The third capture method involves surrounding and capturing the AUV using other underwater equipment. This method requires extremely high game theory algorithms and control precision. If the AUV is equipped with a self-destruct explosive device, it can easily damage the underwater equipment, leading to a significant increase in capture costs. Summary of the Invention

[0012] The AUV capture assembly includes: a first waterproof motor, a drive shaft, a winch, a winch rope, a capture net, several angle adjustment components, several electric launchers, and several powered mass blocks.

The winch is sleeved and fixed on the drive shaft. The winch rope is wound around the winch. The capture net is connected to the end of the winch rope. The several angle adjustment components are fixed to the bottom surface of the unmanned surface vessel and are evenly distributed around the capture net. Each of the several electric launchers is mounted on the angle adjustment components. Each of the several powered mass blocks is movably inserted into the electric launcher. Each powered mass block is evenly connected to the outer edge of the capture net via a connecting rope. The orientation of the electric launcher is adjusted by the angle adjustment components to adjust the launch direction of the powered mass blocks.

[0013] The intelligent automatic unmanned controller is used to realize the automatic control of unmanned surface vessels.

[0014] Furthermore, the unmanned surface vessel includes: a power propulsion unit, a central hull, and two suspended hulls fixed to both sides of the central hull;

[0015] A channel is formed between the two floating hulls on both sides, serving as the mounting slot;

[0016] The power propulsion unit is installed at the end of the suspended hull;

[0017] The central hull is equipped with a waterproof power supply compartment for storing power sources.

[0018] Furthermore, the central hull is equipped with an L-shaped towing rod, which facilitates the connection between the unmanned surface vessel and the towing equipment.

[0019] Furthermore, the upper surface of the suspended hull is provided with several hoisting and fixing rings for hoisting equipment to lift the unmanned surface vessel.

[0020] Furthermore, the AUV capture assembly also includes: a guide roller, a fixed shaft, and a directional wheel;

[0021] Both ends of the guide roller and the fixed shaft are respectively fixed to the side walls of the two suspended hulls;

[0022] The directional wheel is sleeved on the fixed shaft; the stranded wire passes through the directional wheel and the guide roller and is connected to the capture net; the guide roller and the directional wheel guide and support the stranded wire and improve the smoothness of the stranded wire sliding.

[0023] Furthermore, the angle adjustment assembly includes: a second waterproof motor, a connecting rod, a U-shaped seat, a rotating shaft, and a third waterproof motor;

[0024] The second waterproof motor is fixed to the bottom of the unmanned vessel hull on the water surface;

[0025] One end of the connecting rod is connected to the output end of the second waterproof motor;

[0026] The U-shaped seat is fixed to the other end of the connecting rod;

[0027] The rotating shaft is installed through the U-shaped seat;

[0028] The output end of the third waterproof motor is fixedly connected to the rotating shaft;

[0033] The mounting bracket is fixed inside the mounting slot;

[0034] The underwater automatic scanning and detection radar can detect and identify underwater targets, and automatically identify the target autonomous underwater vehicle.

[0035] Furthermore, the end of the powered mass block furthest from the electro-powered launcher is a conical structure, which reduces the resistance to the movement of the powered mass block after launch, thereby increasing the moving speed and distance of the powered mass block, and thus increasing the speed at which the capture net unfolds.

[0037] When in use, the unmanned surface vessel is placed on the water surface of the target sea area, the unmanned surface vessel is started, and the unmanned surface vessel conducts automatic patrol in the target sea area. The radar detection component continuously detects the underwater environment, thereby enabling the detection of autonomous underwater vehicles.

[0038] When the radar detection component detects the autonomous underwater vehicle target, the first waterproof motor starts, drives the drive shaft to rotate, the drive shaft drives the winch to rotate, the winch releases the winch rope, and at the same time, the electric power launcher is activated, which launches the powered mass block at high speed. Under the action of the initial force, the powered mass block moves in different directions, thereby pulling the outer edge of the capture net in multiple directions, so that the capture net can quickly approach the autonomous underwater vehicle and quickly unfold.

[0039] Among them, the second and third waterproof motors can flexibly adjust the launch angle of the power mass block, so that the capture net in the retracted state can be quickly deployed according to actual use needs. The capture net can cover the autonomous underwater vehicle from above, and under the action of the power mass block's own weight, it can complete the wrapping of the autonomous underwater vehicle and complete the automatic capture of the autonomous underwater vehicle.

[0040] After capture, the winch is used to wind up the rope, allowing the capture net to be stored again. The power mass block is then reinstalled on the electric power launcher, enabling the equipment to be reused.
