Description

Technical Field

[0001] This utility model relates to the field of drone capture equipment technology, specifically to a transmitter for capturing drones. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously by an onboard computer, either completely or intermittently. UAVs can be divided into military and civilian applications, with military applications including police applications. In recent years, with the rapid development of the UAV industry, their aerial reconnaissance and reconnaissance functions have been widely used. At the same time, by attaching various functional vehicles to UAVs, they can be equipped with functions such as reconnaissance, video transmission, broadcasting, and attack.

[0003] In related technologies, as the cost of aerial photography drones has decreased, many enthusiasts are buying them for aerial photography. However, some airspaces prohibit drone flights, so police officers control drones in those airspaces and use electromagnetic net launchers installed on the bottom of the drones to capture illegally filming drones.

[0004] However, most existing electromagnetic net launchers are fixed to the bottom of drones and can only control the drone's flight to launch the net, which is inconvenient to use. To solve the above problems, a launcher for capturing drones is proposed. Utility Model Content

[0005] In view of this, the present invention provides a launcher for capturing drones. The present invention clamps and fixes the launch tube of the electromagnetic net thrower through a limiting mechanism, and drives the connecting parts and positioning frame to rotate synchronously through a cornering mechanism, so that the electromagnetic net thrower installed at the bottom of the positioning frame can operate at an angle. The gimbal camera can also be angled and positioned in real time through the gimbal camera. The electromagnetic net thrower is then launched to capture illegal drones. Thus, the electromagnetic net thrower can be adjusted to multiple angles during launch, improving the performance of the equipment.

[0006] To solve the above-mentioned technical problems, this utility model provides a launcher for capturing drones, including a mounting plate installed at the bottom of the drone, an electromagnetic net thrower installed at the bottom of the mounting plate, a support base installed at the front of the mounting plate, a corner mechanism installed on the support base, a connector installed at the bottom of the corner mechanism, a positioning frame installed at the bottom of the connector, a limit mechanism installed at the bottom of the positioning frame, a gimbal camera installed at the top of the positioning frame, and an anti-drop component installed at the rear of the connector, which is connected to the mounting plate.

The bearing seats are used to fix the rotating shaft so that the rotating shaft can rotate on the bearing seats. A rotating shaft is rotatably arranged between the two bearing seats. The rotating shaft is used to drive the connecting piece to rotate. A connecting sleeve is provided on the surface of the rotating shaft. The connecting sleeve is used to connect the rotating shaft to the connecting piece. A drive motor is rotatably arranged through one of the bearing seats.

The positioning seat is used to fix the connecting shaft and connect the connecting shaft to the irregularly shaped connecting rods. A lower sleeve is provided on the surface of the connecting shaft. The lower sleeve is used to connect the connecting shaft to the anti-drop component.

[0009] The anti-fall component includes a hinge connected to the lower sleeve. The hinge connects the lower sleeve to the upper sleeve, preventing the positioning frame from falling when the connecting part is rotated and adjusted. The hinge has an inclined design, and the other end of the hinge is equipped with an upper sleeve. The upper sleeve connects the hinge to the support shaft. The support shaft is rotatably mounted inside the upper sleeve, allowing the hinge to move. Each end of the support shaft has a rotating base, which fixes the support shaft, thereby connecting the support shaft to the mounting plate. The rotating base is also connected to the mounting plate.

[0010] The positioning frame is concave in shape. The limiting mechanism includes a pair of arc-shaped sleeves located inside the positioning frame. The arc-shaped sleeves are used to clamp the outer wall of the electromagnetic net thrower. Threaded holes are provided on both sides of the positioning frame. The threaded holes are used to fix positioning bolts, so that the positioning bolts can drive the arc-shaped sleeves to move on the threaded holes, thereby clamping and positioning the launch tube body. A positioning bolt is provided in each threaded hole. The end of each positioning bolt extends into the positioning frame and is connected to the arc-shaped sleeve on the same side.

[0011] The electromagnetic net thrower includes a launching tube, which is cylindrical in shape, and two arc-shaped sleeves for holding the launching tube.

[0021] This embodiment provides a transmitter for capturing drones. like Figure 1 , 2 As shown in Figures 3, 5, and 7: The corner mechanism 200 includes a pair of bearing seats 202 fixed on the support base 201. The bearing seats 202 are arc-shaped and are fixed to the support base 201 by bolts. The bearing seats 202 are rotatably connected to the rotating shaft 203. The bearing seats 202 are used to fix the rotating shaft 203, allowing the rotating shaft 203 to rotate on the bearing seats 202. A rotating shaft 203 is rotatably arranged between the two bearing seats 202. The rotating shaft 203 is used to drive the connecting member 400 to rotate. The surface of the rotating shaft 203 is provided with... A connecting sleeve 204 is provided, which is welded to the rotating shaft 203.

The drive motor 205 is used to drive the rotating shaft 203 to rotate.

[0022] like Figure 2 , 3 As shown in Figures 4, 5, and 7: Connector 400 includes a pair of irregularly shaped connecting rods 402 connected to the bottom of connecting sleeve 204. The upper ends of the irregularly shaped connecting rods 402 are welded to connecting sleeve 204, and the lower ends are welded to the top of positioning frame 401. The irregularly shaped connecting rods 402 are used to connect connecting sleeve 204 and positioning frame 401. A connecting shaft 403 is rotatably disposed between the bottoms of the two irregularly shaped connecting rods 402. The connecting shaft 403 is rotatably connected to positioning seat 404. The connecting shaft 403 is used for... To connect the anti-fall component 300 to the irregular connecting rod 402, a positioning seat 404 is provided at each end of the connecting shaft 403. The positioning seat 404 is fixedly connected to the irregular connecting rod 402 and is used to fix the connecting shaft 403 so that the connecting shaft 403 is connected to the irregular connecting rod 402. A lower sleeve 405 is provided on the surface of the connecting shaft 403 and is welded to the connecting shaft 403. The lower sleeve 405 is used to connect the connecting shaft 403 to the anti-fall component 300.

[0023] Its effect is as follows: the irregular connecting rod 402 is used to connect the connecting sleeve 204 to the positioning frame 401, the connecting shaft 403 is used to connect the anti-drop component 300 to the irregular connecting rod 402, and the positioning seat 404 is used to fix the connecting shaft 403, so that the connecting shaft 403 is connected to the irregular connecting rod 402.

[0024] like Figure 3 , 4As shown in Figures 5 and 7: The anti-drop component 300 includes a hinge 301 connected to the lower sleeve 405. The lower end of the hinge 301 is hinged to the lower sleeve 405, and the upper end of the hinge 301 is hinged to the upper sleeve 302. The hinge 301 is used to connect the lower sleeve 405 and the upper sleeve 302, so that when the connecting member 400 rotates to adjust its angle, the hinge 301 can prevent the positioning frame 401 from falling. The hinge 301 is designed with an inclination. The other end of the hinge 301 is provided with an upper sleeve 302, which is welded to the support shaft 303. 02 is used to connect the hinge 301 to the support shaft 303. The support shaft 303 is rotatably installed inside the upper sleeve 302. The support shaft 303 is rotatably connected to the rotating base 304. The rotating base 304 is fixed to the mounting plate 101 by bolts. The support shaft 303 is used to allow the hinge 301 to move. A rotating base 304 is provided at each end of the support shaft 303. The rotating base 304 is used to fix the support shaft 303, thereby connecting the support shaft 303 to the mounting plate 101. The rotating base 304 is connected to the mounting plate 101.

[0025] Its effect is as follows: the hinge 301 is connected to the support shaft 303 through the upper sleeve 302, the support shaft 303 is used to allow the hinge 301 to move, the rotating base 304 is used to fix the support shaft 303, thereby connecting the support shaft 303 to the mounting plate 101, and the hinge 301 is used to connect the lower sleeve 405 to the upper sleeve 302, so that when the connecting part 400 rotates to adjust the angle, its hinge 301 can prevent the positioning frame 401 from falling off.

[0026] like Figure 2 , 3 As shown in Figures 4, 5, and 7: The positioning frame 401 has an inverted concave shape. The limiting mechanism 500 includes a pair of arc-shaped sleeves 501 located inside the positioning frame 401. The arc-shaped sleeves 501 are welded to the positioning bolts 503. The arc-shaped sleeves 501 are used to clamp the outer wall of the electromagnetic net thrower 102. Threaded holes 502 are provided on both sides of the positioning frame 401. The threaded holes 502 penetrate the positioning frame 401 and are used to fix the positioning bolts 503, so that the positioning bolts 503 can drive the arc-shaped sleeves 501 to move on the threaded holes 502, thereby clamping and positioning the launch tube body 104. A positioning bolt 503 is provided in each threaded hole 502. The end of each positioning bolt 503 extends into the positioning frame 401 and is connected to the arc-shaped sleeve 501 on the same side.

[0027] Its effect is as follows: the threaded hole 502 is used to fix the positioning bolt 503, so that the positioning bolt 503 can drive the arc-shaped sleeve 501 to move on the threaded hole 502, thereby clamping and positioning the launching tube body 104, so that cylindrical electromagnetic net throwers 102 of different sizes can be installed.

[0028] like Figure 1 , 2 As shown in Figures 6 and 7: The electromagnetic net launcher 102 includes a launching tube 104, which contains an electromagnetic coil, an armature, and a tube (launch tube). The electromagnetic coil is a high-strength conductive coil wound in a spiral shape and is fitted inside the launch tube. When a high-voltage pulse current is applied, a strong magnetic field is instantly generated, driving the armature to move through the magnetic repulsion or attraction force. The launching tube 104 is cylindrical in shape. The armature is made of a high-permeability metal material, with one end connected to the net traction structure and the other end installed inside the launch tube with a spring assembly. The tube is made of a high-strength lightweight material (such as engineering plastics or aluminum alloy). The armature and the net assembly move along its internal channels to ensure the straightness of the launch trajectory, while isolating the magnetic field from external interference and protecting the internal core components from impact. Two arc-shaped clips 501 are used to hold the tube of the launching tube 104. A net projectile module 10 is provided at the front of the launching tube 104. 5. The net projectile module 105 includes a net body and a traction device. The net body is woven from high-strength fiber yarn (such as nylon or aramid), which has the effects of wear resistance, tensile strength, and light weight. The traction head is the driving component of the edge of the net. It is usually made of metal or high-strength plastic. The number of traction heads matches the guide holes of the projectile casing (distributed in a circumferential pattern). After being impacted by electromagnetic driving force, it moves in all directions along the guide holes, causing the net to open quickly and achieve full coverage of the target. The net projectile module 105 is cylindrical. The rear of the launch tube 104 is equipped with a power supply module 106. The power supply module 106 includes a power battery, an energy storage capacitor, and electrical connection wires. The power supply uses a high-capacity lithium battery or a storage battery. The electromagnetic net launcher 102 also includes components such as a microcontroller, a launch switch, and a safety device. The controller on it is connected to the data box wire inside the UAV 100, so that the handle controlling the UAV 100 can launch the net.

[0029] like Figure 1 , 2As shown in Figure 6: The gimbal camera 103 includes a gimbal base 107 mounted on top of the positioning frame 401. The gimbal base 107 uses a high-response stepper motor or servo motor, and is equipped with an encoder to achieve closed-loop angle control, ensuring that the attitude adjustment error is ≤0.1°, meeting the aiming accuracy requirements. A camera 108 is set on the upper part of the gimbal base 107. The camera 108 acquires real-time images and uses image processing algorithms (such as the target detection library of the OpenMV platform and the YOLO lightweight model) to identify targets such as personnel or drones. The control board, energy storage capacitor, lithium battery, gimbal controller, and image processor of the electromagnetic net thrower 102 are integrated into the same housing and achieve data interaction through a low-latency communication interface (such as SPI, CAN). The gimbal camera 103 is electrically connected to the power supply module 106. The gimbal camera 103 also includes an automatic attitude adjustment component, which enables the camera 108 to continuously acquire images and update the target position during target movement. The gimbal operates at 10-30Hz. The frequency of dynamic attitude adjustment ensures that the aiming point always follows the target; at the same time, the encoder provides real-time feedback on the actual angle of the gimbal, compares it with the commanded angle, and corrects the error to avoid cumulative deviation. When the vertical adjustment angle is large, such as the upward tilt angle exceeding 5°, the system automatically increases the transmission power of the electromagnetic net thrower 102 by adjusting the charging voltage of the energy storage capacitor to compensate for the downward trajectory caused by gravity; when the downward tilt angle is large, the power is reduced to prevent the net from flying too far over the target. The installation position of the gimbal camera 103 is on the transmission axis of the electromagnetic net thrower 102.

[0030] Its launch control logic is as follows: When the gimbal base 107 attitude adjustment error is ≤0.2° and the target tracking is stable for 5 consecutive frames without large displacement, the system will send an aiming ready signal to the operator, such as the indicator light illuminating and the background interface prompting. At this time, the capture net is in the ready-to-launch state. After the operator confirms the target through the background monitoring screen or the handheld control panel screen, they can click on the control interface to complete the launch.

[0031] Working principle: The arc-shaped clamps 501 are moved by the positioning bolts 503, thereby controlling the spacing between the arc-shaped clamps 501 to clamp and fix the launching tube body 104 of the electromagnetic net thrower 102. Then, the drive motor 205 drives the rotating shaft 203 to rotate, so that the connecting part 400 at the bottom and the positioning frame 401 can rotate synchronously. This allows the electromagnetic net thrower 102 installed at the bottom of the positioning frame 401 to perform cornering operations. The gimbal camera 103 can also be angled and positioned in real time through the gimbal camera 103. The electromagnetic net thrower 102 is then launched to capture the illegal drone 100. Thus, the electromagnetic net thrower 102 can be adjusted to launch at multiple angles, improving the performance of the equipment.

[0032] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
