Description

A drone net-catching device Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, and more particularly to a UAV net-catching device. Background Technology

[0002] Drones, as unmanned aerial vehicles, are widely used in aerial photography, logistics, agriculture, inspection, and military fields. However, they can also appear in no-fly zones, disrupting order. Therefore, it is necessary to capture drones appearing in no-fly zones. This can be achieved by setting up a net capture device on the drone, which captures the drone by launching a net at it.

[0003] Traditional net-catching devices have a gas storage chamber where gas from a gas cylinder is stored. When the net is launched, the valve in the gas storage chamber opens, releasing high-pressure gas and propelling the traction head outwards, which then carries the net to the target area. Because of the separate gas storage chamber, the device occupies space, increasing its overall size, and the need to pre-store the high-pressure gas poses a safety hazard. Summary of the Invention

[0028] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0029] As shown in Figures 1-4, this application provides a drone net-catching device, including a mounting base 1 and a gas generator 2. The mounting base 1 has a body part 11 and a mounting part 12. The mounting part 12 is located on one side of the body part 11. The body part 11 is provided with a mounting groove 111 and a first mounting hole 112. The first mounting hole 112 is located around the mounting groove 111. The mounting part 12 is provided with a second mounting hole 121, which communicates with the first mounting hole 112. The mounting groove 111 is used to install the capture net, and the first mounting hole 112 is used to install a traction component. The traction component is connected to the capture net. The gas generator 2 is installed in the second mounting hole 121 of the mounting part 12. The gas generator 2 is used to discharge high-pressure gas into the first mounting hole 112 when energized, so as to push the traction component out of the first mounting hole 112. The traction component drives the capture net out of the mounting groove 111.

[0030] The drone net capture device also includes a capture assembly and a connecting cover. The capture assembly includes a capture net and a traction component that are connected to each other. The capture net and the traction component are respectively installed in the mounting groove 111 and the first mounting hole 112 of the main body 11. The connecting cover is installed at the opening on the side of the main body 11 away from the mounting part 12 to prevent the capture net and the traction component from falling out.

[0031] The drone net capture device is installed on the drone body. When in use, the gas generator 2 is powered on to generate high-pressure gas. The high-pressure gas is discharged into the first mounting hole 112 and acts on the traction component to push the traction component out of the first mounting hole 112. The traction component drives the capture net out of the mounting groove 111, so that the traction component and the capture net are shot toward the target to be captured. The capture net wraps around the target to be captured, thereby capturing the target to be captured.

[0032] In this embodiment, the mounting base 1 has a body part 11 and a mounting part 12. The mounting part 12 is located on one side of the body part 11. The body part 11 is provided with a mounting groove 111 and a first mounting hole 112. The mounting part 12 is provided with a second mounting hole 121, which communicates with the first mounting hole 112. The gas generator 2 is installed in the second mounting hole 121 of the mounting part 12. When in use, the gas generator 2 generates high-pressure gas, which is discharged into the first mounting hole 112 for mounting the traction component, so that the high-pressure gas acts on the traction component and is discharged from the first mounting hole 112. There is no need to store high-pressure gas in advance, and therefore no need to set up a separate gas chamber for storing high-pressure gas, which reduces the volume of the net trapping device and improves safety.

[0033] Specifically, the gas generator 2 includes a housing, an electric heating element, and an electric connector. The housing has a storage chamber containing fuel. The electric heating element and the electric connector are connected. The electric heating element is located in the storage chamber. The electric connector is located at the end of the housing away from the main body 11. The electric connector is used to connect to a power source so that the fuel is burned under the action of the electric heating element to generate high-pressure gas. A weak part is provided at the end of the housing facing the main body 11. The weak part is used to rupture under the action of high-pressure gas to form an exhaust port.

[0034] The electric heating element can be a fusible metal wire (such as a nickel-chromium alloy wire). The electrical connectors include a positive pin and a negative pin. The two ends of the fusible metal wire are welded to the positive pin and the negative pin, respectively. The fusible metal wire is immersed in fuel. When the positive pin and the negative pin are connected to an external power source, a short circuit is formed between the positive and negative terminals. A large current flows through the fusible metal wire, which melts rapidly. During the melting process, a large amount of Joule heat and sparks are generated, achieving a high heating effect, igniting the fuel, and producing combustion gas (high-pressure gas). Under the action of the combustion gas, the weak part breaks to form an exhaust port, and the combustion gas is discharged from the exhaust port to the first mounting hole 112.

[0035] When no high-pressure gas is generated, the storage chamber is a sealed structure to prevent fuel leakage; when high-pressure gas is generated in the storage chamber, the weak part ruptures to generate an exhaust port so that the high-pressure gas can be discharged from the exhaust port; at this time, the exhaust port is connected to the first mounting hole 112, and the high-pressure gas discharged from the exhaust port flows to the first mounting hole 112.

[0036] The weak point can be a cross-shaped groove, a circular groove, or a square groove. Taking a cross-shaped groove as an example, the formation of the vent is explained as follows: When high-pressure gas is generated inside the shell, it will exert outward pressure on the shell wall. At the cross-shaped groove, because the continuity of the material is weakened, the stress will concentrate here. When the stress generated by the pressure of the high-pressure gas exceeds the strength limit of the material at the cross-shaped groove, the material will rupture, thus forming the vent.

[0037] In one specific embodiment, as shown in Figures 3-4, the drone net capture device further includes a fastening nut 3. A limiting boss 21 is provided at the end of the housing of the gas generator 2 away from the main body 11. The mounting part 12 is also provided with a limiting groove. The limiting groove is located at the end of the second mounting hole 121 away from the main body 11. The limiting boss 21 and the limiting groove are matched for limiting. The fastening nut 3 is threadedly connected to the housing and presses against the limiting boss 21.

[0038] In this embodiment, the limiting boss 21 of the gas generator 2 is matched with the limiting groove of the mounting part 12, and the fastening nut 3 presses against the limiting boss 21, so that the gas generator 2 is stably installed on the mounting part 12.

[0039] In one specific embodiment, as shown in FIG3, the main body 11 is further provided with a communicating cavity 113, and a plurality of first mounting holes 112 are provided. The plurality of first mounting holes 112 are evenly distributed around the mounting groove 111. The communicating cavity 113 is located between the second mounting hole 121 and the plurality of first mounting holes 112. The plurality of first mounting holes 112 are respectively connected to the communicating cavity 113, and the communicating cavity 113 is connected to the second mounting hole 121.

[0040] There are multiple traction components, each of which is connected to the capture net; each traction component is installed in the corresponding first mounting hole 112.

[0041] When the gas generator 2 is powered on and generates high-pressure gas, the high-pressure gas flows into each of the first mounting holes 112 through the connecting cavity 113, which pushes each traction component, causing multiple traction components to be launched simultaneously, and multiple traction components to simultaneously drive the capture net to be launched.

[0042] Specifically, multiple first mounting holes 112 are provided, and the multiple first mounting holes 112 are evenly distributed around the mounting groove 111. Along the shooting direction of the capture net, the first mounting holes 112 are inclined outward relative to the axis of the main body 11, and the mounting groove 111 is in an expanded state.

[0043] As shown in Figure 3, direction B is the launching direction of the capture net. Referring to Figure 1, along the launching direction of the capture net, the first mounting hole 112 is inclined outward relative to the axis of the main body 11; along the launching direction of the capture net, the mounting groove 111 is in an expanded state. With this arrangement, after multiple traction components simultaneously launch the capture net, the multiple traction components move away from each other, allowing the capture net to open smoothly, which is beneficial for the complete capture of the target.

[0044] In one specific embodiment, the mounting base 1 and the gas generator 2 form a launching device. Multiple launching devices are provided. The UAV net capture device also includes a mounting frame 4. The mounting bases 1 of the multiple launching devices are fixedly connected in the mounting frame 4, and the multiple mounting bases 1 are parallel to each other.

[0045] In this embodiment, each launching device is mounted on a mounting base 1 with a traction component and a capture net. The drone net capture device has multiple launching devices and can capture multiple objects to be captured.

[0046] In order to align the mounting base 1 with the target to be captured, as shown in Figures 4-5, the drone net capture device also includes a mounting frame 4, a rotating frame 5 and a drive assembly. The mounting base 1 is fixedly mounted on the mounting frame 4. The rotating frame 5 is used to connect with the drone body and is rotatably connected to the mounting frame 4. The drive assembly is mounted on the rotating frame 5 and is used to drive the mounting frame 4 to rotate relative to the rotating frame 5 to adjust the orientation of the mounting base 1.

[0047] When performing a capture mission, the rotating frame 5 is fixedly installed on the drone body. During the flight of the drone body, under the driving action of the drive component, the mounting frame 4 rotates relative to the rotating frame 5 so that the mounting base 1 is aligned with the target to be captured. At this time, the gas generator 2 is energized to generate high-pressure gas, which causes the traction component to drive the capture net toward the target to be captured so as to accurately capture the target.

[0048] The drone net capture device also includes a camera device and a control system. The camera device is fixedly mounted on the mounting frame 4, with the axis of the camera device parallel to the axis of the mounting base 1. The camera 7 of the camera device faces the direction of the capture net's launch. The control system is used to control the drive component to drive the mounting frame 4 to rotate relative to the rotating frame 5 based on the real-time images collected by the camera device, so that the mounting base 1 is accurately aligned with the target to be captured.

[0049] Referring to Figures 4 and 5, the drive assembly is installed in the mounting box 51 on one side of the rotating frame 5.

[0050] Specifically, the mounting bracket 4 is provided with a rotating shaft, the rotating bracket 5 rotates around the rotating shaft, and the driving assembly includes a driving component 61 and a transmission assembly. The driving component 61 is connected to the rotating shaft through the transmission assembly.

[0051] The driving component 61 can specifically be a drive motor.

[0052] The drive component 61 transmits the driving force to the rotating shaft through the transmission assembly, causing the rotating shaft to rotate. The rotating shaft drives the mounting bracket 4 to rotate, which in turn causes the mounting bracket 4 to rotate relative to the rotating frame 5.

[0053] More specifically, as shown in Figure 5, the transmission assembly includes a worm 62 and a worm wheel 63 that mesh with each other. The worm 62 is connected to the drive member 61, and the worm wheel 63 is fixedly connected to the rotating shaft.

[0054] During operation, the drive unit 61 drives the worm gear 62 to rotate, the worm gear 62 drives the worm wheel 63 to rotate, and the worm wheel 63 drives the rotating shaft to rotate, so that the mounting bracket 4 rotates relative to the rotating bracket 5.

[0055] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of protection of this application.
