Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) equipment, specifically a UAV countermeasure device. Background Technology

[0002] Drone countermeasures equipment utilizes radio jamming as a primary means of countering drones. By emitting jamming signals in specific frequency bands, it disrupts the communication link between the drone and its remote controller or satellite navigation system, forcing it to land or return to base. Existing drone countermeasures equipment is mostly deployed in handheld or fixed configurations. Handheld devices are highly portable but have limited effective range, and prolonged handling can cause fatigue. Fixed devices offer high power and wide coverage, but are typically complex in structure and cumbersome to install, making them unsuitable for rapid deployment in emergency response and temporary control scenarios. In practical applications, especially in emergency response, large-scale event security, and border patrols, counter-drone equipment needs to possess the capabilities of rapid deployment, rapid withdrawal, and high mobility.

[0003] Existing fixed countermeasures devices typically consist of a signal jamming component and a support structure. The support structure generally suffers from slow deployment and retraction speeds, with most using bolts for fixing or segmented telescopic methods, resulting in lengthy installation and disassembly processes. While some rapid deployment mechanisms rely on motors, hydraulics, or pneumatic systems, although highly automated, they increase equipment weight, power consumption, and potential failure points, and reduce reliability in environments with strong electromagnetic interference or limited power. Therefore, there is a need for a countermeasures device that is simple in structure, easy to operate, and highly reliable, capable of deployment and retraction within seconds without tools and operated by a single person, while also possessing good structural stability and environmental adaptability.

[0004] To address this, we provide a drone countermeasure device. Utility Model Content

[0005] The main objective of this invention is to provide a drone countermeasure device that can effectively solve the problem of slow deployment and retraction speed of the manual operation support part of the drone countermeasure device mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A drone countermeasure device includes a counter-jamming device body. A quick-release disc base is fixed to the bottom of the counter-jamming device body. The quick-release disc base has a cylindrical base and a tray. The cylindrical base and tray are fitted together and fixed to the counter-jamming device body. The tray has multiple sliders that can slide radially on the tray and are fixed with anti-locking strips to restrict the movement of the cylindrical base. A sleeve is located on the lower side of the cylindrical base. One end of the sleeve is connected to a slider, and the other end, after changing direction through the sleeve, is connected to a pull rope of a counterweight plate. The lower side of the quick-release disc base has at least three legs, one end of which rotates with the counterweight plate and the other end of which expands radially outward. Expanding members slide on the legs, rotating with the counterweight plate and limiting the outward expansion angle of the legs.

[0007] Preferably, the cylinder base has a flange portion, a central column portion, and a chuck portion. The flange portion is fixed to the bottom of the counter-interference device body, and a convex ring that grows axially from the outer edge to the center is fixed on the upper side of the chuck portion.

[0008] Preferably, the tray has a base pit at its center that is adapted to the size of the cylinder seat, and the tray has multiple grooves for sliding the slider.

[0009] Preferably, the side of the reverse buckle that is in contact with the cylinder seat is machined with a slope that is in contact with the convex ring in the chuck portion.

[0010] Preferably, the slider is provided with a return spring with one end fixed to the center of the tray and the other end connected to a positioning block, and the positioning block is fixed on the tray.

[0011] Preferably, the expansion member has a collar that slides on the support leg and an ear plate fixed thereto, and a support arm is rotatably connected to the ear plate, and the support arm is rotatably connected to the counterweight plate.

[0012] Preferably, the support leg has a female leg and a female leg. The female leg is movably inserted into the female leg and rotatably connected to the tray. The lower end of the female leg is fixed with an internal tube that slides inside the female leg. The upper end of the internal tube is provided with a flange structure to prevent the internal tube from detaching. The female leg has a limiting hole.

[0013] Preferably, the collar is machined with a through hole, the ear plate has an insert shaft in the through hole and a round cap block is fixed at one end, the round cap block and the ear plate have a return spring and contact the support arm rod, the support arm rod and the ear plate rotate to be in the same direction or perpendicular to the insert shaft, and the insert shaft is inserted into or slides out of the limiting hole.

[0014] Preferably, the end of the support arm that contacts the round cap block is machined into an arc shape to facilitate rotation.

[0015] Preferably, an extension support is connected to the lower side of the counterweight plate, and the extension support has a straight rod connected to the counterweight plate and a support ring fixed to the lower end of the straight rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. It has the ability to deploy quickly; by setting the cooperation between the cylinder base and the tray, and restricting and fixing the cylinder base through the anti-locking strip on the sliding slider, the assembly of the counter-interference device body can be completed quickly; then, through the cooperation of the counterweight plate and the pulling rope, the anti-locking strip can be directly slid to fit with the cylinder base; at the same time, under the gravity of the counterweight plate with the cooperation of the expansion support, the female leg and the female leg extend due to gravity, and through the counterweight plate and the pressure applied on the counterweight plate, the legs can be quickly deployed, and the maximum length of the legs can be locked at the same time, so as to achieve rapid deployment.

[0017] 2. It has the ability to be easily stored; by setting the extension of the mother leg and the child leg, and in conjunction with the structure in the expansion support, when retracting, the counterweight plate is first lifted to a certain height by extending the lower leg. Under the elastic force of the return spring, the buckle can be released from the restriction of the cylinder base, and the counter-interference device body can be quickly removed. Then, continue to lift it up, and use the upper leg to continuously lift the counterweight plate so that the tray and the support leg are in a vertical position. Then, the tray is gradually lowered, and under the action of gravity, the child leg is inserted into the mother leg for storage. The operation is simpler and smoother, and quick storage is achieved.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-6 As shown, a UAV countermeasure device includes a counter-jamming unit 1. A quick-release disc base 2 is fixed to the bottom of the counter-jamming unit 1. The quick-release disc base 2 has a cylindrical base 21 and a tray 22. The cylindrical base 21 has a flange, a central column, and a chuck. The flange is fixed to the bottom of the counter-jamming unit 1. A convex ring that grows axially from the outer edge to the center is fixed to the upper side of the chuck. The tray 22 has a pit at its center that matches the size of the cylindrical base 21. The cylindrical base 21 fits snugly against the tray 22 and is fixed to the counter-jamming unit 1. The tray 22 has multiple sliders 23 and multiple grooves for sliding the sliders 23. The sliders 23 can slide radially on the tray 22 and are fixed with a counter-fastening strip 24 to restrict the movement of the cylindrical base 21. The side of the counter-fastening strip 24 that fits against the cylindrical base 21 has a slope that fits against the convex ring in the chuck. The lower side of the cylinder base 21 has a sleeve with a pull rope 25 connected to a slider 23 at one end and to a counterweight plate 26 at the other end after the direction is changed by the sleeve. The slider 23 has a return spring 27 with one end fixed to it and the other end connected to a positioning block 28 on the side facing the center of the tray 22. The positioning block 28 is fixed to the tray 22. The lower side of the quick-release tray base 2 has at least three legs 3 with one end rotating with it and the other end radially expanding outward. The legs 3 have expansion members 4 that slide with the counterweight plate 26 and limit the outward expansion angle of the legs 3. The expansion member 4 has a collar 41 that slides on the legs 3 and an ear plate 42 fixed thereto. A support arm 46 is rotatably connected to the ear plate 42 and is rotatably connected to the counterweight plate 26.

[0028] It should be noted that in this embodiment, the counter-interference device body 1 is a conventional technical component, which is fixed to the cylinder base 21 by bolts and forms a fit with the base pit on the tray 22, thus settling therein; the slider 23 slidably disposed on the tray 22 moves with the anti-locking strip 24, which can form a restrictive and fixed effect with the cylinder base 21. In this embodiment, there are three sliders 23. The slope of the anti-locking strip 24 fits with the convex ring of the cylinder base 21, and under the pulling force of the pull rope 25 and the counterweight plate 26, it can more stably lock the cylinder base 21 onto the tray 22. The number of pull ropes 25 corresponds to the number of sliders 23 and they are all fixed to the counterweight plate 26. Under the pulling action of the counterweight plate 26, the sliders 23 can be pulled and slid simultaneously. The reset spring 27 is compressed when the sliders 23 are pulled. When the counterweight plate 26 is lifted, the elastic force of the reset spring 27 allows the sliders 23 to disengage from the cylinder base 21, enabling the rapid removal of the cylinder base 21 and its fixed counter-interference device body 1. The sleeve is used to guide the pull ropes 25 to change their pulling direction. When the pull ropes 25 are pulled by the gravity of the counterweight plate 26 and the added force, the support arm 46 on the counterweight plate 26 rotates, and the support arm 46 and the ear plate 42 rotate to extend the legs 3, causing the lower end of the legs 3 to tend to expand outwards, thus enabling rapid deployment of the legs 3 and facilitating deployment. This achieves operational convenience.

[0029] Optionally, the support leg 3 has a female leg 31 and a female leg 32. The female leg 32 is movably inserted into the female leg 31 and rotatably connected to the tray 22. The lower end of the female leg 32 is fixed with an internal tube 33 that slides inside the female leg 31. The upper end of the internal tube 33 is provided with a flange structure to prevent the internal tube 33 from detaching. The female leg 32 has a limiting hole. The lower end of the female leg 31 is threaded with a spherical foot pad.

[0030] The collar 41 has a through hole, and the ear plate 42 has an insert shaft 43 in the through hole and a round cap block 44 is fixed at one end. The round cap block 44 and the ear plate 42 have a return spring 45 that contacts the support arm 46. The support arm 46 and the ear plate 42 rotate to be in the same direction or perpendicular to the insert shaft 43, and the insert shaft 43 inserts into or slides out of the limiting hole.

[0031] The end of the support arm 46 that contacts the round cap block 44 is machined into an arc shape to facilitate rotation.

[0032] It should be noted that in this embodiment, both the female leg 31 and the female leg 32 are made of square tubes to maintain relative stability during sliding. The internal tube 33 is slidably disposed inside the female leg 31 to maintain a certain overall strength and sliding stability when the female leg 31 and the female leg 32 are extended. The dome design of the round cap block 44, together with the support arm 46, facilitates sliding. When the support arm 46 rotates to be parallel to the insertion shaft 43, and the female leg 31 and the female leg 32 reach their maximum length, the limiting hole corresponds to the through hole, and the insertion shaft 43 will be inserted into the limiting hole, thus completing the limitation of the combined length of the female leg 31 and the female leg 32 and the limitation of the outward expansion of the support leg 3. At this time, the pull rope 25 pulls the anti-fastening strip 24 on the slider 23 to form a fixed limitation with the cylinder seat 21, achieving the ability of rapid overall deployment.

[0033] Optionally, an extension support 5 is connected to the lower side of the counterweight plate 26. The extension support 5 has a straight rod 51 connected to the counterweight plate 26 and a support ring 52 fixed to the lower end of the straight rod 51.

[0034] It should be noted that the straight rod 51 and the support ring 52 are used when retracting. When retracting is required, the lower limb is inserted into the support ring 52 to lift the counterweight plate 26, causing the counterweight plate 26 to move up a certain distance. At this time, the slider 23 descends under the action of the return spring 27, and the anti-locking bar 24 slides away from the restriction on the cylinder base 21. At this time, the counter-interference device body 1 and the cylinder base 21 can be directly taken out.

[0035] Working principle: When the device is in the state of the counter-interference device body 1 as shown in the figure, it is in the deployment state; when it needs to be retracted, the counterweight plate 26 is lifted by inserting the lower limb into the support ring 52, so that the counterweight plate 26 moves up a certain distance. At this time, the slider 23 descends under the action of the return spring 27, and the anti-locking bar 24 slides away from the restriction on the cylinder base 21. At this time, the counter-interference device body 1 and the cylinder base 21 can be directly taken out. Then, continue lifting, using the upper limbs to continuously raise the counterweight plate 26; simultaneously, due to the lifting of the counterweight plate 26, the support arm 46 and the counterweight plate 26 rotate, the support arm 46 and the ear plate 42 rotate, and the end of the support arm 46 acts on the round cap block 44 through its arc, causing the spring force of the return spring 45 squeezed by the round cap block 44 to be released, and the round cap block 44 and the end of the support arm 46 slide, and the support arm 46 and the insertion shaft 43 will move from a parallel state to a vertical state; at this time, the insertion shaft 43 will gradually disengage from the limiting hole on the sub-leg 32, so that the female leg 31 and the sub-leg 32 have the ability to slide and insert; at this time, the tray 22 and the support leg 3 maintain a near-vertical posture, and then the tray 22 is gradually lowered, and under the gravity of the quick-release tray seat 2 and other components, the sub-leg 32 is inserted into the female leg 31 for storage; at this time, the overall storage is completed, the operation is simpler and smoother, and a rapid storage effect is achieved.

[0036] When deployment is required, the pallet 22 is lifted. Through the gravity of the leg 32 and components such as the counterweight plate 26 and the expansion member 4, the leg 32 slides against the female leg 31 and the collar 41, extending the leg 3 to its length limit. The weight of the expansion member 4 then expands the lower end of the leg 3 outwards, increasing the force on the counterweight plate 26 and causing it to expand rapidly. Supported by the support arm 46, the outward expansion of the leg 3 reaches its limit. At this point, the pull rope 25 on the counterweight plate 26 changes its pulling direction through the sleeve, causing the anti-locking strip 24 on the slider 23 to slide closer to the center of the pallet 22. At this point, the deployment of the outrigger 3 is completed; then, by inserting the lower limb into the support ring 52, the counterweight plate 26 is lifted, causing the counterweight plate 26 to move upward a certain distance. At this point, the slider 23 descends under the action of the return spring 27, and the anti-locking bar 24 slides away from the restriction on the cylinder base 21. At this point, the counter-interference device body 1 and the fixed cylinder base 21 are placed directly on the pit on the tray 22. The lower limb is released from lifting the extension support 5. Through the gravity of the counterweight plate 26 and the extension support 5, the anti-locking bar 24 is restricted and fixed to the cylinder base 21 under the action of the return spring 27, thus completing the rapid deployment.
