Description
Technical Field
[0001] The present invention relates to the technical field of low, slow, and small target capture devices, and particularly to an unmanned aerial vehicle (UAV)-borne low, slow, and small target rope net capture system. Background Art
[0002] Low, slow, and small targets refer to low-altitude, slow-speed, and small aircraft, including rotor UAVs, fixed-wing UAVs, balloons, and other aircraft. These aircraft have low flight altitudes, small volumes, and low costs, and have been widely popularized and used worldwide. For the use of such aircraft, some applications are beneficial, but some can also cause harm. For example, using UAVs to obtain secrets, invade others' privacy, and interfere with normal aviation. Therefore, it is necessary to manage such aircraft in an orderly manner and take effective measures to capture harmful and dangerous suspicious aircraft.
[0003] In view of this, we have proposed an unmanned aerial vehicle (UAV)-borne low, slow, and small target rope net capture system that can achieve the capture of low, slow, and small targets. Summary of the Invention
[0004] The purpose of the present invention is to provide an unmanned aerial vehicle (UAV)-borne low, slow, and small target rope net capture system to solve the problems existing in the above-mentioned prior art, which can achieve the capture of low, slow, and small targets, has a simple structure, and is convenient to operate.
[0005] To achieve the above purpose, the present invention provides the following solution:
[0006] The present invention provides an unmanned aerial vehicle (UAV)-borne low, slow, and small target rope net capture system, including a UAV, a base, a traction block, a traction block launching module, a capture net, a capture net protective cover, and a protective cover. The base is fixedly installed at the bottom of the UAV. The upper end of the capture net protective cover is fixed to the bottom surface of the base. The protective cover is arranged at the bottom opening end of the capture net protective cover. The top surface of the protective cover is fixedly connected to one of the traction blocks as the protective cover traction block. The protective cover traction block is connected to the base through a rope. The capture net is folded and placed in the capture net protective cover. The capture net is connected to the base through a rope. Four traction blocks are evenly connected to the outer edge of the capture net as capture net traction blocks. Four traction block launching modules are evenly arranged along the circumferential direction on the outside of the capture net protective cover. One traction block launching module is arranged in the middle of the capture net protective cover. One of the capture net traction blocks is installed in each of the outer traction block launching modules, and the protective cover traction block is installed in the middle traction block launching module. Each of the traction block launching modules is signal-connected to a controller, and the controller controls the launching of the protective cover traction block and each of the capture net traction blocks.
[0007] In one embodiment, the traction block launching module includes a launching cylinder, a spring, a limiting ball, a trigger rod, an electric push rod, and a limiting cylinder. The electric push rod is installed at one end of the launching cylinder. The trigger rod is arranged inside the launching cylinder and fixedly connected to the output end of the electric push rod. A limiting cylinder is sleeved outside the trigger rod, and the limiting cylinder is fixedly connected to the launching cylinder. A plurality of limiting through holes are evenly arranged along the circumferential direction on the side wall of the limiting cylinder. The limiting ball is movably arranged in the limiting through holes. The traction block is arranged inside the launching cylinder.

The trigger rod includes a small-diameter section and a large-diameter section connected to each other. The traction block launching module is initially in a locked state. The extrusion section compresses the spring to make the limiting groove correspond to the limiting ball. At the same time, the large-diameter section radially limits the limiting ball and radially extrudes the limiting ball into the limiting groove. When the electric push rod drives the trigger rod to move so that the small-diameter section corresponds to the limiting ball, the limiting ball can break out of the limiting groove to release the locking of the traction block.

[0027] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] As Figures 1-5 shown, this embodiment provides a UAV-borne low, slow, and small target net capture system, including a UAV, a base 1, a traction block 2, a traction block launching module 3, a capture net 4, a capture net protective cover 5, and a protective cover 6. The base 1 is fixedly installed at the bottom of the UAV. The upper end of the capture net protective cover 5 is fixed on the bottom surface of the base 1. The protective cover 6 is arranged at the bottom opening end of the capture net protective cover 5. A traction block 2 is fixedly connected to the top surface of the protective cover 6 as the protective cover traction block. The protective cover traction block is connected to the base 1 through a rope. The capture net 4 is folded and placed in the capture net protective cover 5. The capture net 4 is connected to the base 1 through a rope. Four traction blocks 2 are evenly connected to the outer edge of the capture net 4 as the capture net traction blocks. Four traction block launching modules 3 are evenly arranged along the circumference outside the capture net protective cover 5. A traction block launching module 3 is arranged in the middle of the capture net protective cover 5. A capture net traction block is installed in each of the outer traction block launching modules 3, and the protective cover traction block is installed in the middle traction block launching module 3. Each traction block launching module 3 is signal-connected to the controller, and the controller controls the launching of the protective cover traction block and each capture net traction block.
[0029] During use, after the carrier UAV approaches above the low, slow, and small target 13, the controller controls the launching of the protective cover traction block and each capture net traction block. The protective cover 6 opens, and the capture net 4 unfolds under the traction of the capture net traction blocks and captures the low, slow, and small target 13 below it, with a simple structure and convenient operation.
[0030] In this embodiment, the traction block launching module 3 includes a launching cylinder body 7, a spring 8, a limit ball 9, a trigger rod 10, an electric push rod 11 and a limit cylinder 12.

The trigger rod 10 includes a small-diameter section 101 and a large-diameter section 102 which are connected to each other; the traction block launching module 3 is initially in a locked state. The pressing section 202 compresses the spring 8 to make the limit groove 203 correspond to the limit ball 9. At the same time, the large-diameter section 102 radially limits the limit ball 9, and radially extrudes the limit ball 9 outward into the limit groove 203 to realize the locking of the traction block 2; when the electric push rod 11 drives the trigger rod 10 to move and the small-diameter section 101 corresponds to the limit ball 9, the limit ball 9 can radially move inward and break away from the limit groove 203 to release the locking of the traction block 2.

The electric push rods 11 in the four outer traction block launching modules 3 are connected in parallel to the same output end of the driver, avoiding the influence of different drivers on the synchronization of the motors in the electric push rods 11. In addition, motors with consistent characteristics are used to reduce errors, thereby ensuring the consistency of the motor speeds and realizing synchronous triggering; the electric push rods 11 in the middle traction block launching module 3 are connected to the other output end of the driver.
[0033] In this embodiment, the middle part of the capture net 4 is connected to the base 1 through a rope, so that the capture net 4 can be evenly deployed.
[0034] In this embodiment, the capture net protective cover 5 is a frustum-shaped protective cover, and the diameter of the upper end of the capture net protective cover 5 is smaller than that of the lower end.
