Description

Technical Field

[0001] This invention relates to the field of highway construction equipment technology, and in particular to a drone for highway patrol. Background Technology

[0002] With the integration of intelligent transportation and the low-altitude economy, drone technology, with its advantages of wide-area coverage from high altitudes, real-time data transmission, and contactless inspection of high-risk areas, has become an important tool for intelligent highway management. Its core objective is to solve the problems of low efficiency, high risk, and numerous blind spots in traditional manual inspections through automated and precise inspection methods, while providing dynamic data support for traffic management.

[0003] The publicly disclosed patent document CN112550705B discloses a highway traffic violation patrol drone, which includes a drone fuselage, an outer anti-collision ring, rotating blades, an inner movable ring, and a camera. The drone fuselage has an overall S-shaped structure, and the camera is movably mounted on the bottom of the drone fuselage. This device prevents the drone from crashing into obstacles such as utility poles or tree trunks during flight by setting an outer anti-collision ring that extends beyond the outer edge of the rotating blades, thus avoiding the drone falling due to the rotating blades stopping. At the same time, the second support rod in this invention can retract into the sliding cavity on the first support rod, thereby reducing the overall size of the drone and making it easier to store.

[0004] When existing highways are under construction, drones are needed to inspect and collect data on various sections of the highway to plan maintenance schedules and identify details that need attention. In this process, in order to improve the clarity of data collection, drones usually fly at low altitudes. However, the flight time of drones is generally only 30-60 minutes, which is difficult to meet the needs of long-distance continuous inspection. Strong winds can affect the flight stability and data collection accuracy of drones. Highways usually have a large number of vehicles traveling at speeds of 80 km / h or more. If a drone flying at low altitude is close to vehicles during data collection, it is easily affected by the airflow generated by the vehicle speed, which can affect data collection and have a certain impact on the safety of the drone. Summary of the Invention

A bidirectional hinge block and a guide spherical block are fixedly installed on the outside of the vertical inserts respectively. An active electric telescopic assembly is fixedly installed on the top of the first positioning base plate.

[0009] Optionally, four sets of protective shield assemblies are provided on the outside of the main drone component. The protective shield assembly includes an external protective shield that wraps around the outside of the drone's fan blades. An information collection component is installed on the top of the main drone component.

[0010] Optionally, the outer wall of the external protective cover is provided with a guide groove, the surface of the guide groove is provided with a vertical sliding groove, a slider is slidably installed on the outer side of the guide groove through the vertical sliding groove, and a two-way hinge rod is hinged to the side of the slider away from the guide groove.

[0011] Optionally, an arc-shaped slider is hinged to the side of the bidirectional hinge rod away from the slider, and an arc-shaped guide frame is slidably installed on the outer side of the arc-shaped slider through an arc-shaped groove.

[0012] Optionally, an elastic ball is rotatably mounted on the side of the arc-shaped guide frame away from the bidirectional hinge rod, and a first spring is fixedly mounted between the slider inside the vertical slide groove and the inner wall of the guide groove.

[0013] Optionally, the UAV landing support assembly further includes a hinge frame hinged to both sides of the second positioning base plate. Each side of the hinge frame is hinged with an arc-shaped hinge block. The two sets of arc-shaped hinge blocks are hinged together and rotatably mounted on the outside of the first positioning base plate.

[0014] Optionally, an elastic telescopic frame is fixedly installed at the end of the arc-shaped hinge block away from the second positioning base plate. There are two sets of elastic telescopic frames, and a retaining block is hinged to one side of the two sets of elastic telescopic frames facing each other.

[0015] Optionally, both sides of the second positioning base plate are hinged with a first hinge rod, the end of the first hinge rod away from the second positioning base plate is hinged with a second hinge rod, and the end of the second hinge rod away from the first hinge rod is hinged to the outside of the first positioning base plate.

[0019] 1.

[0020] 2. The airflow is guided to rotate by the elastic ball combined with the groove of the arc-shaped guide frame, so that the kinetic energy of the airflow is converted into heat energy. At the same time, the slider and the first spring form a vertical buffer module, so that the impact force is absorbed by the hinged fold of the two-way hinge rod when it collides, avoiding rigid damage to the drone. In addition, the external protective cover completely covers the drone's fan blades, thereby effectively blocking the stones flying on the highway and reducing the risk of hardware damage.

[0021] 3. The flexible telescopic frame and clamping block adjust the clamping force through forward and reverse motors to enable the drone to temporarily stop and charge, thereby supporting long-distance patrols. The hydraulic telescopic components control the landing speed of the drone, thereby reducing energy loss. Attached Figure Description

[0033] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] The components of the embodiments of the invention described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0035] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 invention based on the specific circumstances.

[0038] like Figures 1-4As shown, the present invention proposes a drone for highway patrol, comprising a main drone component 1, which includes a drone support bracket 101. Four extension positioning plates 102 are fixedly installed on both sides of the drone support bracket 101. A positioning shaft 103 is fixedly installed at the end of each extension positioning plate 102 away from the drone support bracket 101. A drone fan blade 104 is rotatably mounted inside the positioning shaft 103. Four sets of protective cover assemblies 2 are provided on the outside of the main drone component 1. Each protective cover assembly 2 includes an external protective cover 201 that wraps around the outside of the drone fan blade 104. An information acquisition component 5 is installed on the top of the main drone component 1. A guide groove 203 is formed on the outer wall of the external protective cover 201. A vertical sliding groove is formed on the surface of the guide groove 203. A slider 208 is slidably mounted on the outside of the guide groove 203 through the vertical sliding groove. The slider 208 is away from the guide groove. A bidirectional hinge rod 206 is hinged to one side of 203. An arc-shaped slider 205 is hinged to the side of the bidirectional hinge rod 206 away from the slider 208. An arc-shaped guide frame 204 is slidably installed on the outer side of the arc-shaped slider 205 through an arc-shaped groove. An elastic ball 202 is rotatably installed on the side of the arc-shaped guide frame 204 away from the bidirectional hinge rod 206. A first spring 207 is fixedly installed between the slider 208 inside the vertical groove and the inner wall of the guide groove 203. The UAV of this application achieves quadcopter flight through four UAV fan blades 104. The entire device has wind resistance stability and power redundancy design, thereby ensuring safe flight in complex airflow environments. The UAV is made of carbon fiber composite material. The strength of carbon fiber composite material is 2-3 times that of aluminum alloy, but the weight is lower than that of aluminum alloy. Therefore, the UAV can improve the torsional and bending resistance of the fuselage without increasing the weight of the UAV.

[0039] The drone uses information acquisition component 5 to collect images of the highway surface, which are then used to identify visible construction problems such as cracks and worn road markings. Information acquisition component 5 includes thermal imaging equipment and camera components. The thermal imaging equipment detects hidden hazards such as road surface voids, water accumulation, or interlayer peeling based on the temperature differences of the highway, so as to facilitate the later construction of the highway.

[0040] The camera assembly and thermal imaging equipment generate a high-precision three-dimensional point cloud model through electrical signals and transmit it to the terminal. The high-precision three-dimensional point cloud model is used to assist staff in analyzing the deformation of highway structures.

[0041] During the flight of the drone, the drive unit on the drone drives the drone blades 104 to rotate along the positioning shaft 103. This is existing technology and will not be described in detail here. The drone flies on the highway via the four drone blades 104. Since there are many small stones on the highway, these small stones may be scattered by the impact of the vehicles when they are traveling at high speed. When these stones fly to the position of the drone blades 104, the external protective cover 201 blocks the stones, which improves the safety of the drone during flight.

[0042] Meanwhile, when the drone flies to an obstacle, if a collision occurs between the two, the elastic ball 202 is driven by external pressure to move the arc-shaped guide frame 204 toward the guide groove 203. The arc-shaped slide groove opened in the arc-shaped guide frame 204 guides the arc-shaped slider 205 to slide along the arc-shaped track. The two-way hinge rod 206 folds along the arc-shaped slider 205 and the arc-shaped slider 205. The thrust transmitted by the two-way hinge rod 206 drives the slider 208 to slide outward along the vertical slide groove. The slider 208 buffers the external force in the vertical slide groove. At the same time, the first spring 207 uses its elasticity to buffer the thrust transmitted by the slider 208, thereby avoiding damage to the drone from collision with the obstacle.

[0043] Meanwhile, when the UAV is impacted by external airflow, the airflow rubs against the elastic ball 202 impacting in the corresponding direction. The elastic ball 202 converts the impact of the airflow into rotation along the arc-shaped guide frame 204, consuming part of the airflow. At the same time, the surface of the elastic ball 202 is covered with microporous polymer material, which can convert the kinetic energy of the airflow into heat energy with a dissipation efficiency of up to 20%. When the airflow impacts, the arc-shaped guide frame 204 guides the airflow to rotate through the arc-shaped groove, reducing the direct impact on the fan blades, thereby improving the stability of the UAV when encountering airflow during flight.

[0044] like Figures 5-9As shown, a drone landing support assembly 3 is installed at the bottom of the main drone component 1. The drone landing support assembly 3 includes a second positioning base plate 303 fixedly installed at the bottom of the drone support bracket 101. A hydraulic telescopic assembly 305 is fixedly installed in the middle of the second positioning base plate 303. A first positioning base plate 301 is fixedly installed at the output end of the hydraulic telescopic assembly 305. The drone landing support assembly 3 also includes a hinge frame 304 hinged to both sides of the second positioning base plate 303. Arc-shaped hinge blocks 302 are hinged to both sides of the hinge frame 304. The two sets of arc-shaped hinge blocks 302 are hinged together and rotatably mounted on the first positioning base plate. On the outer side of 301, an elastic telescopic frame 306 is fixedly installed at the end of the arc-shaped hinge block 302 away from the second positioning base plate 303. There are two sets of elastic telescopic frames 306. A retaining block 307 is hinged to the side of the two sets of elastic telescopic frames 306 facing each other. A first hinge rod 308 is hinged to both sides of the second positioning base plate 303. A second hinge rod 309 is hinged to the end of the first hinge rod 308 away from the second positioning base plate 303. The end of the second hinge rod 309 away from the first hinge rod 308 is hinged to the outer side of the first positioning base plate 301. An elastic telescopic frame 306 is fixedly installed at the bottom of the arc-shaped hinge block 302. There are two sets of elastic telescopic frames 306. Two sets of elastic telescopic frames 306 are equipped with locking blocks 307 on their facing sides. When the drone flies into the air, the hydraulic telescopic assembly 305 drives the first positioning base plate 301 to move upward. The first positioning base plate 301 then drives the hinge frame 304 to open outward. The two relatively hinged arc-shaped hinge blocks 302 are subjected to outward pulling force and expand outward along the hinge point. That is, the arc-shaped hinge blocks 302 drive the elastic telescopic frame 306 away from the ground. During this process, the second positioning base plate 303 and the first positioning base plate 301 drive the first hinge rod 308 to fold. This facilitates the drone's flight to a higher altitude. At the same time, when the drone needs to stop at a designated point to collect data, it can also be used for other purposes. The main covering around the highway is the protective crossbeam. When the drone moves onto a section of the protective crossbeam, the hydraulic telescopic component 305 drives the first positioning base plate 301 to move downwards. The arc-shaped hinge block 302 then moves toward the position of the protective crossbeam. The clamping block 307 is rotated by the forward and reverse motor mounted on the elastic telescopic frame 306 until the clamping block 307 grips the protective crossbeam. It should be noted that the elastic telescopic frame 306 and the clamping block 307 can be replaced according to the shape of the protective crossbeam, thereby enabling the drone to collect information on the protective crossbeam at any time, serving as a rest point, extending the information collection time of the highway section, and saving some power.

[0045] like Figure 7 and Figure 10As shown, a flow-deflecting component 4 is installed inside the UAV landing support assembly 3. The flow-deflecting component 4 includes an inclined beam 402 fixedly installed on the outside of the first positioning base plate 301. Two sets of vertical inserts 407 are rotatably installed on one side of the inclined beam 402. A bidirectional hinge block 405 and a guide spherical block 406 are fixedly installed on the outside of the vertical inserts 407, respectively. Dampers are installed at the connection points on both sides of the bidirectional hinge block 405 to reduce the risk of resonance. An active electric telescopic assembly 403 is fixedly installed on the top of the first positioning base plate 301. The output end is hinged with a movable clamping rod 404, which is hinged to the outside of two sets of bidirectional hinge blocks 405. A bidirectional spherical rod 408 is hinged inside the guide spherical block 406. A spherical storage block 409 is hinged to the end of the bidirectional spherical rod 408 away from the guide spherical block 406. An electrically retractable spoiler 401 is fixedly installed at the bottom of the spherical storage block 409. The electrically retractable spoiler 401 is set perpendicular to the ground when the UAV is not in flight. An electrically retractable assembly is fixedly installed inside the electrically retractable spoiler 401. The spoiler 401 is telescopically mounted via an electrically retractable assembly. Made of high-strength ABS plastic, the electrically retractable spoiler 401 addresses the complex airflow patterns created around the vehicle at high speeds, in addition to the strong airflow present on highways. This complex airflow is primarily influenced by Bernoulli's principle and the vehicle's shape. At the front of the vehicle, the airflow is pushed aside by the front, resulting in slightly higher pressure and creating a "positive pressure zone." On the sides of the vehicle, the airflow flows along the surface, at a speed slightly lower than the vehicle's speed, but due to the vehicle's obstruction, the pressure remains higher than the surrounding environment. At the rear of the vehicle, after the vehicle passes, the rear... Create space and rapidly replenish air to form a "negative pressure zone," where the pressure is significantly lower than the surrounding environment. These airflow characteristics cause surrounding objects to be subjected to thrust or attraction. When the drone is directly in front of the vehicle, it will be subjected to a frontal impact, that is, a direct collision with the airflow. When the drone is near the vehicle body, it will be pushed away by the airflow. When the drone is near the rear of the vehicle, it will be attracted to the rear of the vehicle by the airflow. At the same time, when the vehicle is overtaking, if the drone is in the negative pressure zone at the rear of the vehicle, it will be quickly sucked into the vicinity of the rear of the vehicle, which is extremely risky. In addition, the faster the vehicle speed, the higher the airflow speed and the greater the impact intensity.

[0046] It is important to note that the airflow speed around a vehicle is lower than the vehicle's own speed. For example, the airflow speed on both sides of the vehicle is about 80%-90% of the vehicle's speed, which is still enough to pose a threat to the drone's flight. Therefore, when the drone is in a strong airflow, or near the front or body of the vehicle, the surface of the electrically retractable spoiler 401 is equipped with pressure sensors. The sampling rate of the pressure sensors on the surface of the electrically retractable spoiler 401 is set to 1kHz, which can distinguish between the positive pressure zone at the front and body of the vehicle (pressure > 100Pa) and the negative pressure zone at the rear of the vehicle (pressure < -50Pa). The response time of the active electrically retractable component 403 is < 0.1s. The spoiler is rotated at an angle of 0°-90° by the movable clamping rod 404. When the electrically retractable spoiler 401 is in a vertical state, its surface receives external airflow. When the wind pressure is high, the active electric telescopic component 403 extends. The output end of the active electric telescopic component 403 drives the movable clamping rod 404 to move forward. The bidirectional hinge block 405 and the guide spherical block 406 rotate counterclockwise along the inclined beam 402. At this time, the bidirectional spherical rod 408 is pulled. The bidirectional spherical rod 408 drives the electric telescopic spoiler 401 to move towards the position of the drone fan blade 104 through the knob force of the spherical storage block 409. The electric telescopic spoiler 401 diverts the thrust generated by the airflow below, that is, the front area and the body area. The strong airflow is diverted with the cooperation of the protective cover component 2, thereby reducing the impact on the rotation of the drone fan blade 104, thus ensuring the stability and safety of the drone in the above situation.

[0047] When the drone is in the rear area of ​​the vehicle, the electric retractable spoiler 401 flips at a larger angle, and the airflow attracted by the rear of the vehicle is blocked by the electric retractable spoiler 401, so that the drone can leave this area by relying on the normal airflow of the drone fan blades 104, thereby improving the safety of the drone flight.

[0048] The electrically retractable spoiler 401 can be opened via an electrically retractable assembly, thereby effectively increasing the area covered directly below the drone fan blades 104 and blocking the airflow generated by the vehicle.

[0049] To explain, in the front area, the electrically retractable spoiler 401 unfolds and deflects at an angle of 30°-45°, thereby directing airflow to both sides of the drone. In the rear area, the electrically retractable spoiler 401 flips to 60°-90°, forming a barrier to block the intake airflow. The bidirectional spherical rod 408, the guide spherical block 406, and the spherical storage block 409 are ball joint structures, which allow the electrically retractable spoiler 401 to perform ±10° adaptive deflection, avoiding jamming when the electrically retractable spoiler 401 deflects.

[0050] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
