Description

Technical Field

[0001] The present invention relates to the technical field of low-altitude unmanned aerial vehicles (UAVs), and in particular to a police UAV for low-altitude law enforcement. Background Art

[0002] At urban street intersections, traffic lights are important tools for directing traffic, and their normal operation is crucial to maintaining traffic order and ensuring traffic safety.

[0003] However, in actual applications, due to various reasons (such as equipment aging, power failure, etc.), traffic lights occasionally malfunction, resulting in interruption of traffic control, which may cause traffic jams and even traffic accidents.

[0004] In response to traffic light failures, the traditional approach mainly relies on on-site traffic police to direct traffic.

[0005] However, this approach has obvious limitations: first, traffic police may not be able to arrive at the scene of the breakdown in time, especially during peak traffic hours or in remote areas; second, even if traffic police arrive at the scene, it will take a certain amount of time to arrange temporary traffic control measures, during which time traffic congestion may further worsen.

[0006] With the rapid development of drone technology, drones are being used increasingly widely in low-altitude law enforcement, traffic monitoring and other fields.

[0007] However, existing drone technology mainly focuses on reconnaissance and monitoring functions, and its emergency response capabilities for sudden situations such as traffic light failures are still limited.

[0008] Specifically, when a traffic light at a city street intersection malfunctions, although drones can conduct low-altitude reconnaissance and cooperate with on-site traffic police for direction, when the traffic police are unable to arrive at the scene in time, the drones cannot carry their own signal light boxes to the fault site in time to direct and clear traffic, resulting in increasingly serious traffic congestion.

[0009] Therefore, in response to this defect in the existing technology, it is particularly important to propose a low-altitude law enforcement police drone that can carry a signal light box and go to the fault site in time to conduct traffic control and clearing.

[0010] This type of drone can not only respond quickly when a traffic light fails, effectively shortening traffic interruption time, but also achieve sustainable energy utilization through its own energy conversion mechanism, improving the autonomy and environmental protection of the equipment.

[0011] SUMMARY OF THE INVENTION

[0012] The purpose of the present invention is to solve the shortcomings of the existing technology that when a traffic light at an urban street intersection fails, the only way to clear the blockage is to rely on low-altitude reconnaissance by drones and the command of on-site traffic police. When the traffic police cannot arrive at the scene in time, the drones cannot carry the signal light boxes to the scene in time to clear the blockage, which easily leads to increasingly serious blockages. The present invention proposes a low-altitude law enforcement police drone.

[0013] In order to achieve the above object, the present invention adopts the following technical solutions:

[0014] A low-altitude law enforcement police drone, comprising a drone body, a plurality of wings fixed to the sides of the drone, a power assembly mounted on the wings, a self-contained signal light mechanism, comprising a spare box detachably mounted to the bottom of the drone body, and a signal light box retractably disposed within the spare box for replacing a faulty streetlight at an intersection and directing traffic. A first fixing bracket is fixed to the bottom of the drone body, located in front of the spare box, and a camera mounted on the first fixing bracket.

[0015] A driving component 1 for driving the signal light box to extend and retract along the vertical direction of the standby box, located in the standby box and connected to the signal light box;

[0016] The energy conversion mechanism includes support bases fixedly provided along both sides of the standby box, a flip plate rotatably mounted on the support bases, and a solar panel fixedly provided on the bottom end of the flip plate;

[0017] A second driving component for driving the solar panel to unfold, connected between the standby box and the flip plate;

[0018] A lifting support mechanism, comprising a plug-in board detachably mounted on the bottom of the drone, an electric push rod fixed to the bottom of the plug-in board, and a support frame fixed to the bottom end of the drone body;

[0019] The first driving assembly includes a second screw rod rotatably connected to the standby box, a first hinge block screwed with the second screw rod, and a scissor lever hinged to the first hinge block;

[0020] The second driving component includes a first screw rod vertically connected to the bottom wall of the standby box, and the first screw rod is threadedly connected to a push plate that slides and limits with the side of the standby box, and a hinged rod hinged between the push plate and the flip plate.

[0021] Furthermore, a slide groove is provided on the top of the spare box, and a second hinge block hinged to the two scissor rods is slidably connected in the slide groove.

[0022] Furthermore, a first bevel gear and a second bevel gear that mesh with each other are fixedly provided on the top end of the first screw rod and the second screw rod, respectively.

[0023] Furthermore, the power assembly includes a drive motor fixed on the wing and a propeller blade fixed on an output shaft of the drive motor.

[0024] Furthermore, two first mounting plates for fixing the spare box are fixedly provided at the bottom of the drone body, and a first mounting groove for the first mounting plug is provided at the top of the spare box.

[0025] Furthermore, a second mounting plate, a second mounting slot provided on the plug-in board for plugging the second mounting plate, and a limit plate for positioning the plug-in board are fixedly provided on the bottom of the drone body.

[0026] Furthermore, the front side of the drone body is provided with an inclined heat dissipation hole and a heat dissipation fence fixed in the heat dissipation hole.

[0027] Furthermore, support frames are fixedly provided at both side edges of the bottom of the drone body.

[0028] Compared with the prior art, the advantages of the present invention are:

[0029] 1. This solution uses a drone to quickly reach the faulty intersection, using a first screw to drive the two first hinged blocks toward each other, and using a scissor lever to drive the two second hinged blocks to slide on the signal light box. The signal light box follows the movement trajectory of the two scissor levers and extends out of the spare box to replace the faulty signal light. At the same time, the meshing between the first and second bevel gears causes the second screw to rotate synchronously with the first screw, pushing the plate upward under the action of the second screw. The hinged lever uses the support base as a fulcrum to drive the solar panel to rotate and unfold to a horizontal state. The solar panel fully absorbs solar energy and converts it into electricity. The electricity is not only stored in the battery but also directly powers the replacement signal light box, ensuring a continuous and stable power supply for the signal light box and its normal operation.

[0030] 2. The deployment and utilization of solar panels in this solution enables the drone to absorb and convert solar energy into electricity, providing power support for the drone itself while achieving sustainable energy utilization, reducing dependence on external power sources, and improving the device's autonomy and environmental friendliness.

[0031] 3. This solution uses an electric push rod to adjust the height of the support frame and the drone body before landing, ensuring that the drone can be clearly seen by vehicle drivers and pedestrians during landing, enhancing the safety and visibility of the scene and reducing safety hazards caused by unclear vision.

DETAILED DESCRIPTION

[0041] The technical solution of this embodiment will be clearly and completely described below in conjunction with the drawings in this embodiment. Obviously, the described embodiment is only a part of this embodiment, rather than all the embodiments.

[0042] Reference Figures 1-8A low-altitude law enforcement police drone includes a drone body 1, a plurality of wings 101 fixed to the sides of the drone, and a power assembly 102 mounted on the wings 101. The power assembly 102 includes a drive motor 1020 fixed to the wings 101 and propeller blades 1021 fixed to the output shaft of the drive motor 1020. The power assembly 102 also includes:

[0043] The self-contained signal light mechanism includes a spare box 2 detachably mounted on the bottom of the drone body 1, and a signal light box 406 retractably disposed within the spare box 2 for directing traffic at a faulty street light intersection. A fixing bracket 1030 is fixed to the bottom of the drone body 1, located in front of the spare box 2, and a camera 103 mounted on the fixing bracket 1030.

[0044] A driving assembly 1 for driving the signal light box 406 to extend and retract vertically along the standby box 2 is located inside the standby box 2 and connected to the signal light box 406. The driving assembly 1 includes a second screw rod 401 rotatably connected to the standby box 2, a first hinge block 403 screwed with the second screw rod 401, and a scissor lever 404 hinged to the first hinge block 403. A slide groove is provided on the top of the standby box 2, and a second hinge block 405 hinged to the two scissor levers 404 is slidably connected in the slide groove.

[0045] The energy conversion mechanism includes a support base 201 fixed along both sides of the spare box 2, a flip plate 202 rotatably mounted on the support base 201, and a solar panel 203 fixed on the bottom end of the flip plate 202;

[0046] A second drive assembly for driving the solar panel 203 to unfold is connected between the standby box 2 and the flip plate 202. The drive assembly includes a first screw rod 3 that is vertically connected to the bottom wall of the standby box 2. The first screw rod 3 is threadedly connected to a push plate 301 that is limited by the sliding movement of the side of the standby box 2, and a hinged rod 302 that is hinged between the push plate 301 and the flip plate 202. The top of the first screw rod 3 and the second screw rod 401 are respectively fixed with a first bevel gear 4 and a second bevel gear 402 that mesh with each other;

[0047] In this embodiment, the driving motor 1020 runs at a high speed, driving the propeller blades 1021 to rotate rapidly, so that after the drone body 1 flies to the designated place, the first screw rod 3 starts to rotate. Due to the limited sliding design between the push plate 301 and the spare box 2, the push plate 301 will move upward steadily under the action of the screw rod, and the push plate 301 is connected to the flip plate 202 through the hinged rod 302, driving the solar panel 203 to rotate and unfold until it reaches a horizontal state. The solar panel 203 can fully absorb the energy of the sun and efficiently convert it into electrical energy, which is input into the storage battery for storage. The second screw rod 401 can also rotate synchronously, and because the thread directions at both ends of the second screw rod 401 are opposite to the thread directions of the two first hinge blocks 403, the two first hinge blocks 403 will be close to each other under the action of the screw rod, and through the linkage of the two scissor rods 404, the two second hinge blocks 405 will also be close to each other, and the signal light box 406 will be able to move downward smoothly and extend out of the spare box 2, so as to replace the faulty signal light in time, and effectively speed up the traffic clearing speed.

[0048] Reference Figure 3 and Figure 4 The bottom of the drone body 1 is fixed with two first mounting plates 204 for fixing the spare box 2 and a first mounting groove for the first mounting plug-in provided on the top of the spare box 2.

[0049] In this embodiment, the first mounting plate 204 is plugged into the first mounting slot to facilitate the removal or installation of the spare box 2 .

[0050] Reference Figure 1 and Figure 8 The lifting support mechanism includes a plug-in board 502 detachably mounted on the bottom of the drone, an electric push rod 503 fixed to the bottom of the plug-in board 502, and a support frame 7 fixed to the bottom end of the drone body 1. The bottom of the drone body 1 is fixed with a second mounting plate 5, a second mounting slot provided on the plug-in board 502 for plugging in the second mounting plate 5, and a limit plate 501 for positioning the plug-in board 502.

[0051] In this embodiment, the plug-in cooperation between the second mounting plate 5 and the second mounting groove realizes the installation or removal of the plug-in board 502, and the limiting plate 501 is used to limit the plug-in board 502 when the plug-in board 502 is plugged into the second mounting plate 5.

[0052] Reference Figure 1 The front side of the drone body 1 is provided with inclined heat dissipation holes and a heat dissipation fence 6 fixed in the heat dissipation holes. Support frames 7 are fixed at the two side edges of the bottom of the drone body 1. A storage battery for powering various components is installed in the drone body 1.

[0053] In this embodiment, the heat generated by the long-term operation of the drone body 1 can be dissipated through the heat dissipation holes. The heat dissipation fence 6 prevents debris from entering the drone body 1 through the heat dissipation holes, and the storage battery can receive the electrical energy converted by the solar panel 203 for storage and continuously power the various components of the drone body 1.

[0054] The implementation principle of a low-altitude law enforcement police drone in an embodiment of the present application is as follows: when a traffic light at a street intersection fails, we first accurately plug the spare box 2 into the first mounting plate 204 through the first mounting slot, and then firmly plug the plug-in board 502 into the second mounting plate 5 through the second mounting slot. At this time, the operation of the drone body 1 is flexibly controlled with the help of a remote controller, and the drive motor 1020 runs at high speed, driving the propeller blades 1021 to rotate rapidly.

[0055] During the rotation of the blades, not only will an upward lift be generated, but a backward force will also be exerted on the surrounding air. According to the physical principle of action and reaction, the air will correspondingly produce a forward thrust on the blades. It is this thrust that drives the drone to fly steadily and work closely with the camera 103 to accurately reach the designated location.

[0056] When the UAV successfully reaches the fault intersection, the electric push rod 503 starts to work, driving the second fixing frame 504 to move slowly downward, thereby accurately adjusting the distance between the support frame 7 and the UAV body 1, ensuring that when the UAV body 1 lands later, its height can be clearly seen by vehicle drivers and pedestrians, ensuring visibility on the scene.

[0057] Next, the drone body 1 lands smoothly, and the support frame 7 makes smooth contact with the ground. At this point, the adjustment motor is activated, driving the first screw 3 to begin rotating. Due to the limited sliding design between the push plate 301 and the spare box 2, the push plate 301 moves steadily upward under the action of the screw. The push plate 301 is connected to the flip plate 202 via a hinged rod 302, using the support base 201 as a fulcrum to drive the solar panel 203 to rotate and unfold until it reaches a horizontal position. In this way, the solar panel 203 can fully absorb the sun's energy and efficiently convert it into electrical energy. This electrical energy can be input into the battery for storage or directly provide power support for the drone body 1, achieving sustainable energy utilization.

[0058] At the same time, thanks to the close engagement between the first bevel gear 4 and the second bevel gear 402, when the first screw rod 3 rotates, the second screw rod 401 will also rotate synchronously. Since the thread directions at both ends of the second screw rod 401 are opposite to the thread directions of the two first hinge blocks 403, the two first hinge blocks 403 will approach each other under the action of the screw rod, and through the linkage action of the two scissor rods 404, the two second hinge blocks 405 are also driven to approach each other. Under this ingenious mechanical transmission, the signal light box 406 can move downward smoothly and extend out of the spare box 2, replacing the faulty signal light in time, effectively speeding up the traffic clearing speed, avoiding the embarrassing situation of increasingly serious traffic congestion due to signal light failure, and ensuring that the traffic order at the intersection can be quickly restored to normal.

[0059] All structures in this application can be selected in terms of material and length according to actual usage. The accompanying drawings are all schematic structural diagrams, and the specific actual dimensions can be appropriately adjusted.

[0060] The above is only a preferred specific implementation method of this embodiment, but the protection scope of this embodiment is not limited to this. Any technician familiar with this technical field can make equivalent replacements or changes based on the technical solution of this embodiment and its inventive concept within the technical scope disclosed in this embodiment, and they should be covered by the protection scope of this embodiment.
