Description

Technical Field

[0001] The present invention relates to the technical field of release and pointing of unmanned aerial vehicles, and more specifically to a nighttime high-altitude pointing reconnaissance unmanned aerial vehicle. Background Art

[0002] Reconnaissance drones that release fluorescent powder at high altitudes at night have many uses, which are mainly based on their high-altitude reconnaissance, target marking and environmental adaptability. The main use is night reconnaissance and monitoring. Drones can conduct reconnaissance and monitoring at high altitudes at night, using the cameras and sensors on board to capture information on the ground or specific targets. Releasing fluorescent powder can help drones mark target locations more clearly at night, improving the accuracy and efficiency of reconnaissance.

[0003] In the existing public documents, the Chinese patent announcement number CN109018348A discloses an air-land dual-purpose reconnaissance drone. This technology solves the problem of short flight time of the rotorcraft by using a separate power supply method for the rotor flight platform and the car, and improves the shooting time; it has strong environmental adaptability and ignores the terrain. It can carry the car to reach the target area with complex conditions to complete the shooting task; it has low noise and is not easy to alarm animals, which is convenient for observing the most natural state of animals; in addition, it can also play its advantages in other fields such as military reconnaissance and earthquake relief, and can be secondary developed to complete other tasks. However, this technology still has the following problems.

[0004] When a reconnaissance drone is used at night, it is necessary for the reconnaissance drone to fly to a high altitude, find the target area through the onboard camera, and then the drone can fly to the designated reconnaissance area to point to the area. However, it is difficult to achieve lateral synchronous displacement coverage and pointing to the target area during the pointing process, and it is difficult to achieve longitudinal synchronous displacement coverage and pointing to the target area. As a result, the reconnaissance drone has a small pointing coverage displacement area and a small pointing range at high altitudes at night, and there are many blind spots in the pointing mark, making it difficult for ground operators to quickly find the area marked by the reconnaissance drone. For this reason, a reconnaissance drone with high-altitude pointing at night is needed. Summary of the invention

[0015] 3. The present invention adopts a pressurized dispersion release component. The booster fan pressurizes the directional mark fluorescent powder inside the fluorescent powder release bottle.

[0037] In this embodiment, as shown in the attached Fig. 9 -Attached Fig.10 As shown, the pressurized dispersion release component includes a release tube 31 fixedly connected to the bottom end of the fluorescent powder release bottle 13; the bottom end of the release tube 31 is threadedly connected to an electric valve 32, and a connecting block 33 is fixedly installed on one side of the electric valve 32, the bottom end of the connecting block 33 is fixedly connected to a reinforcement column 34, and the bottom end of the reinforcement column 34 is fixedly connected to a dispersion bucket 35.

The cross-section of the docking hole 36 is circular, and a gap is provided between the electric valve 32 and the directional dispersion hopper 35.

[0039] The working principle of the night-time high-altitude pointing reconnaissance drone of the present invention is as follows: First, when the present invention conducts nighttime high-altitude reconnaissance, the support frame 18 first supports the guide frame 17, and the guide frame 17 supports the drone housing 1. Then the threaded cover 38 is rotated forward, and the thread between the threaded cover 38 and the fluorescent powder release bottle 13 is separated, and the pointing mark fluorescent powder is poured into the fluorescent powder release bottle 13, and then the threaded cover 38 is reversed, and the thread between the threaded cover 38 and the fluorescent powder release bottle 13 is closed. The wireless controller 19 is connected through the remote control in the hands of the ground operator, and multiple rotating motors 14 are started through the wireless controller 19. The rotating motor 14 drives the lifting blades 15 to rotate, so that the drone housing 1 drives the slot column 2 to rise, and the slot column 2 drives the reconnaissance camera 21 to rise to the high altitude in the dark night, and the position of the reconnaissance target area is collected through infrared imaging of the reconnaissance camera 21. After the reconnaissance determines the target area, the drone housing 1 is kept hovering at the target position at high altitude at night.

[0040] Secondly, when the present invention performs pressurized dispersion release, the wireless controller 19 is powered by the battery 20, and the wireless controller 19 starts the booster fan 37, which boosts the pressure of the directional marking fluorescent powder inside the fluorescent powder release bottle 13, and then opens the electric valve 32 through the wireless controller 19. The directional marking fluorescent powder inside the fluorescent powder release bottle 13 is poured into the release tube 31, enters the electric valve 32 through the release tube 31, and is released and sprayed on the outer wall of the directional dispersion bucket 35 by the electric valve 32. The connecting block 33 is supported by the electric valve 32, and the connecting block 33 supports the reinforcing column 34, and the reinforcing column 34 provides a reinforcing support force for the directional dispersion bucket 35. In this way, the directional marking fluorescent powder can diffuse outward along the outer wall of the directional dispersion bucket 35, and at the same time, the directional marking fluorescent powder is discharged downward along the inside of the docking hole 36, so that the directional marking fluorescent powder can be released and sprayed downward, and the directional marking operation from the high altitude at night to the ground is realized for the target area.

[0041] Then, when the present invention performs lateral synchronous displacement release direction, the screw rod 3 is driven to rotate by the reduction motor 4, and the screw rod 3 drives the articulated sleeve block 5 to move up under the action of the thread transmission force, and at the same time, the articulated sleeve block 5 slides up along the inner wall of the slot column 2, and the articulated sleeve block 5 drives the two articulated shafts 6 to move up synchronously, and the articulated shaft 6 drives the bottom end of the push sleeve rod 7 to move up, and the push sleeve rod 7 drives the linkage shaft 8 to move left, and the other linkage shaft 8 moves right, and the linkage shaft 8 drives the sleeve groove block 9 to move left along the outer wall of the guide column 16. The sleeve groove block 9 slides leftward along the inner wall of the guide frame 17, and the sleeve groove block 9 drives the support block 10 to move leftward, the support block 10 drives the pillar 11 to move leftward, the pillar 11 makes the limit slide bar 29 move leftward, the limit slide bar 29 drives the sleeve rotating block 12 to move leftward, and at the same time, the sleeve rotating block 12 drives the gear 30 to move leftward.

[0042] At the same time, the limit slide bar 29 drives the rack 28 to move left, the rack 28 drives the sliding sleeve 27 to move left, the sliding sleeve 27 slides left along the inner wall of the concave push frame 25, and the sliding sleeve 27 slides left along the outer wall of the push column 26. In this way, the sleeve rotating block 12 drives the fluorescent powder release bottle 13 to move left, and the other fluorescent powder release bottle 13 moves right. The fluorescent powder release bottle 13 drives the release tube 31 to move the electric valve 32 to move left, and the electric valve 32 moves the pointing mark fluorescent powder to the left for injection, and the other electric valve 32 moves the pointing mark fluorescent powder to the right for injection. In this way, the two fluorescent powder release bottles 13 can synchronously displace and release the pointing mark fluorescent powder horizontally, and the release direction area is wider.

[0043] At the same time, when the present invention performs longitudinal synchronous displacement release pointing, the drone housing 1 supports the micro-electric cylinder 22, the wireless controller 19 starts the micro-electric cylinder 22, the micro-electric cylinder 22 pushes the concave push frame 25 forward, the concave push frame 25 drives the push column 26 forward, the push column 26 drives the two sliding sleeves 27 to move forward synchronously, and the two sliding sleeves 27 respectively drive the two racks 28 to move forward synchronously. The rack 28 moves forward and slides on the inner wall of the limit slide 29, the rack 28 drives the gear 30 to rotate clockwise, the gear 30 rotates clockwise on the outer wall of the pillar 11, and the gear 30 drives the sleeve rotating block 12 to rotate clockwise, the sleeve rotating block 12 drives the fluorescent powder release bottle 13 to rotate clockwise, the fluorescent powder release bottle 13 makes the release tube 31 rotate clockwise, and the release tube 31 drives the electric valve 32 to rotate clockwise, so that the two electric valves 32 can release the pointing mark fluorescent powder in a clockwise rotation.

[0044] The concave push frame 25 is sensed by the longitudinal distance sensor 24. When the distance value sensed by the longitudinal distance sensor 24 is the same as the displacement distance set by the wireless controller 19, the wireless controller 19 starts the micro-electric cylinder 22 to drive the concave push frame 25 to move backward, and the concave push frame 25 drives the push column 26 to make the two sliding sleeves 27 move backward synchronously, and the sliding sleeve 27 drives the rack 28 to move backward, and the rack 28 drives the gear 30 to rotate counterclockwise. The gear 30 drives the sleeve rotating block 12 to rotate counterclockwise, and the sleeve rotating block 12 makes the fluorescent powder release bottle 13 rotate counterclockwise, and the fluorescent powder release bottle 13 drives the release tube 31 to rotate counterclockwise, and the release tube 31 drives the electric valve 32 to rotate counterclockwise, and the electric valve 32 rotates counterclockwise to release and eject the pointing mark fluorescent powder. As the micro-electric cylinder 22 drives the concave push frame 25 to move back and forth continuously, the two electric valves 32 can continuously rotate the pointing mark fluorescent powder to release and eject it longitudinally.

[0045] Then, the distance of the sleeve groove block 9 is sensed by the lateral distance sensor 23. When the distance value sensed by the lateral distance sensor 23 is the same as the distance set by the wireless controller 19, the reduction motor 4 is turned off by the wireless controller 19. In this way, the pointing mark fluorescent powder can cover the high-altitude position of the drone shell 1 in the dark night in a large area, so that the ground personnel can quickly know the reconnaissance area where the drone shell 1 is located based on the pointing mark fluorescent powder covered by the large area displacement, and the pointing mark fluorescent powder will fall to the ground, so that the ground personnel can also see the pointing mark fluorescent powder on the ground from a distance and quickly know the location of the marked area.
