Description

Technical Field

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

[0002] With the acceleration of urbanization, community management faces increasing challenges, such as security monitoring, environmental monitoring, and emergency response. Traditional community patrols mainly rely on manual patrols, which are not only inefficient but also have blind spots and cannot achieve 24-hour uninterrupted monitoring. In recent years, drone technology, due to its advantages such as high mobility, wide field of view, and flexible operation, has been gradually applied to the field of community patrols, effectively improving patrol efficiency and coverage.

[0003] However, existing community patrol drones still have the following technical shortcomings in practical applications:

[0004] Drones rely on a main power source for power. Once the main power supply is depleted, the drone will lose power and may fall from the sky, causing equipment damage or even endangering the safety of people on the ground. Current technology lacks an emergency protection mechanism in the event of a main power failure. When a drone loses power due to a power failure or other unforeseen circumstances, current technology often relies on simple descent devices or passive descent, failing to effectively control the landing attitude and increasing the risk of equipment damage.

[0005] Patrol drones are typically equipped with high-definition cameras for image capture, but in complex outdoor environments, camera lenses are easily contaminated with dust, rain, or dirt, leading to blurry images or monitoring failure. Most existing drones rely on regular manual cleaning and cannot be automatically cleaned in real time, affecting the continuity and reliability of patrol missions.

[0006] Based on this, this solution proposes a drone device for community patrols. Utility Model Content

[0007] The purpose of this invention is to provide a drone device for community patrols to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a community patrol drone device, comprising a main body, a mounting box fixedly installed on the top of the main body, and drive propellers rotatably mounted on all four sides of the main body; a camera fixedly installed on the main body, and a mounting box fixedly installed on the bottom of the main body; a rotating motor fixedly installed on the mounting box, and a round rod rotatably mounted inside the mounting box; a reciprocating lead screw fixedly sleeved on the output shaft of the rotating motor, a reciprocating rack threadedly sleeved on the reciprocating lead screw; a reciprocating gear fixedly sleeved on the round rod, and a threaded drive rack at one end of the round rod. The cleaning brush has a main power supply fixedly installed inside its main body. An electric telescopic rod and a backup power supply are fixedly installed on the bottom inner wall of the mounting box, and a fixing box is fixedly installed on one side of the mounting box. A parachute pack is fixedly installed on the output shaft of the electric telescopic rod. A sliding rod is fixedly installed inside the fixing box, and two sliding sleeves are slidably sleeved on the sliding rod. Each sliding sleeve is fixedly installed with a cover plate and a linkage rack. Two drive motors are fixedly installed on one side of the fixing box, and linkage gears are fixedly sleeved on the output shafts of the two drive motors. The two linkage gears mesh with the corresponding linkage racks.

[0009] Preferably, a wireless control module is fixedly installed inside the mounting box.

[0010] By adopting the above technical solution and through the built-in wireless control module, the drone device of this utility model can realize remote wireless control, which enhances the flexibility and convenience of operation. The wireless control module enables operators to monitor the drone in real time and issue commands within a safe distance, thereby improving the safety and efficiency of patrol tasks.

[0011] Preferably, support rods are fixedly installed at the four bottom corners of the main body, and buffer pads are fixedly installed at the bottom end of any one of the support rods.

[0012] By adopting the above technical solution, the support rod provides a stable support structure for the drone, while the buffer pads can buffer the drone when it lands or accidentally touches the ground, reducing the impact and damage to the drone body. This design improves the stability and durability of the drone and extends its service life.

[0013] Preferably, a slide rail is fixedly installed inside the mounting box, and a slider is slidably installed on the slide rail, with the slider being fixedly connected to a reciprocating rack.

[0014] By adopting the above technical solution, the cooperation between the slide rail and the slider enables the reciprocating rack to move smoothly and accurately within the mounting box, thereby driving the reciprocating rotation of the cleaning brush. This design improves the motion accuracy and stability of the cleaning brush, ensuring the cleaning effect of the camera lens.

[0015] Preferably, the cleaning brush is made of fiber cloth.

[0016] Using the above technical solution, the fiber cloth material is soft, wear-resistant, and has good water absorption, making it suitable for cleaning camera lenses. It can effectively remove dust, rainwater, or stains from the lens without causing scratches or damage to the lens surface. This choice ensures the effectiveness of the cleaning brush and the clarity of the camera.

[0017] Preferably, both cover plates are made of acrylic material.

[0018] Using the above technical solution, acrylic material has the characteristics of high transparency, light weight and good weather resistance. Using it as the material of the cover plate can maintain the appearance and transparency of the drone device, reduce the overall weight of the device and improve flight performance. At the same time, acrylic material also has good weather resistance, can adapt to various outdoor environments and extend the service life of the cover plate.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 This utility model provides a technical solution: a community patrol drone device, including a main body 1, a mounting box 4 fixedly installed on the top of the main body 1, and drive propellers 3 rotatably installed on all four sides of the main body 1, a camera 10 fixedly installed on the main body 1, and a mounting box 12 fixedly installed on the bottom of the main body 1, a rotating motor 13 fixedly installed on the mounting box 12, and a round rod 14 rotatably installed inside the mounting box 12, a reciprocating screw 17 fixedly sleeved on the output shaft of the rotating motor 13, a reciprocating rack 16 threadedly sleeved on the reciprocating screw 17, a reciprocating gear 15 fixedly sleeved on the round rod 14, and a cleaning brush 11 threadedly installed at one end of the round rod 14, a main power supply fixedly installed inside the main body 1, a slide rail fixedly installed inside the mounting box 12, a slider slidably installed on the slide rail, the slider being fixedly connected to the reciprocating rack 16, and the cleaning brush 11 being made of fiber cloth.

[0030] In this embodiment, the following is implemented: A mounting box 4 is fixedly installed on the top of the main body 1 of the drone device for installing key components. Drive propellers 3 are rotatably mounted on all four sides of the main body 1 to provide flight power. A camera 10 is fixedly mounted on the main body 1 for image acquisition during community patrols. A mounting box 12 is fixedly mounted on the bottom of the main body 1, containing components such as a cleaning mechanism. A rotary motor 13 is fixedly mounted on the mounting box 12 as the power source for the cleaning mechanism. A round rod 14 is rotatably mounted inside the mounting box 12, and a reciprocating gear 15 is fixedly sleeved on the round rod 14. A reciprocating lead screw 17 is fixedly sleeved on the output shaft of the rotary motor 13, and a reciprocating rack 16 is threaded onto the reciprocating lead screw 17. When the rotary motor 13 operates, the reciprocating rack 16 is driven to reciprocate through the reciprocating lead screw 17. The movement of the reciprocating rack 16 drives the reciprocating rotation of the reciprocating gear 15 and the round rod 14 through meshing. A cleaning brush 11 is threaded onto one end of the rod 14. When the rod 14 rotates, the cleaning brush 11 reciprocates to clean the lens of the camera 10.

A slide rail is fixedly installed inside the mounting box 12, and a slider is slidably installed on the slide rail. The slider is fixedly connected to the reciprocating rack 16 to ensure that the reciprocating rack 16 can move smoothly and accurately. When the drone is conducting community patrols, the camera 10 is responsible for collecting images. If the lens of the camera 10 is contaminated by dust, rainwater, or stains, affecting the image quality, the rotating motor 13 can be started. The rotating motor 13 drives the cleaning brush 11 to reciprocate through the reciprocating screw 17 and the reciprocating rack 16, thus cleaning the lens. The cooperation between the slide rail and the slider ensures the movement accuracy and stability of the cleaning brush 11. The main power supply is fixedly installed inside the main body 1 to provide power to the drone.

[0031] Combination Figures 1-5 As shown, in this embodiment, an electric telescopic rod 20 and a backup power supply 19 are fixedly installed on the bottom inner wall of the mounting box 4, and a fixing box 6 is fixedly installed on one side of the mounting box 4. A parachute pack 9 is fixedly installed on the output shaft of the electric telescopic rod 20. A sliding rod 23 is fixedly installed inside the fixing box 6. Two sliding sleeves 24 are slidably sleeved on the sliding rod 23. A cover plate 2 and a linkage rack 22 are fixedly installed on each of the two sliding sleeves 24.

The two linkage gears 21 mesh with the corresponding linkage racks 22 respectively. Both cover plates 2 are made of acrylic material. A wireless control module 18 is fixedly installed inside the mounting box 4.

[0032] In this embodiment, when the main power supply is depleted or malfunctions, the drone will lose power. At this time, the wireless control module 18 will trigger an emergency landing procedure. The two drive motors 5 inside the mounting box 6 will drive the linkage gear 21 to rotate. The linkage gear 21 meshes with the linkage rack 22, causing the sliding sleeve 24 to slide on the sliding rod 23. The movement of the sliding sleeve 24 will open the cover plate 2, thus opening the top of the mounting box 4. The cover plate 2 is made of acrylic material, which has good transparency and impact resistance, ensuring the safety and reliability of the drone during flight. Subsequently, the electric telescopic rod 20 will quickly extend and push the parachute pack 9 outward. The deployment of the parachute pack 9 can effectively slow down the descent speed of the drone, reduce the risk of equipment damage, and protect the safety of personnel on the ground. The backup power supply 19 provides necessary power support when the main power supply fails, ensuring the normal operation of key components such as the wireless control module 18, the electric telescopic rod 20, and the drive motors 5, until the drone lands safely.

[0033] Combination Figures 1-5 As shown, in this embodiment, support rods 8 are fixedly installed at the four bottom corners of the main body 1, and buffer pads 7 are fixedly installed at the bottom end of any one of the support rods 8.

The cleaning brush 11 at one end of the round rod 14 rotates back and forth accordingly to wipe and clean the lens of camera 10. The cleaning brush 11 is made of fiber cloth, which has good cleaning effect and wear resistance, ensuring the clarity and service life of the lens of camera 10.

[0041] 3. Emergency landing protection mechanism

[0042] Main power failure response: When the main power supply is depleted or malfunctions, the drone will lose power. At this time, the wireless control module 18 will trigger an emergency landing procedure. The two drive motors 5 in the mounting box 6 will drive the linkage gear 21 to rotate. The linkage gear 21 meshes with the linkage rack 22, causing the sliding sleeve 24 to slide on the sliding rod 23. The movement of the sliding sleeve 24 will open the cover plate 2, which can open the top of the mounting box 4. The cover plate 2 is made of acrylic material, which has good transparency and impact resistance, ensuring the safety and reliability of the drone during flight. Then, the electric telescopic rod 20 will quickly extend and push the parachute pack 9 outward. The deployment of the parachute pack 9 can effectively slow down the descent speed of the drone, reduce the risk of equipment damage, and protect the safety of personnel on the ground. The backup power supply 19 provides necessary power support in the event of a main power failure, ensuring the normal operation of key components such as the wireless control module 18, the electric telescopic rod 20, and the drive motors 5, until the drone lands safely.
