Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a low-noise community inspection UAV system based on a bladeless aerodynamic ring. Background Technology

[0002] With the accelerating pace of urbanization, the scale of densely populated areas such as residential communities and commercial complexes is expanding daily, posing unprecedented challenges to their security inspection and emergency management. Traditional manual inspection methods are not only inefficient and costly, but also struggle to achieve comprehensive, blind-spot-free real-time monitoring, especially in dangerous or inaccessible areas such as the exterior walls of high-rise buildings, fire exits, and narrow spaces, where significant monitoring blind spots exist.

[0003] Against this backdrop, drone technology, with its unique maneuverability and flexibility, is gradually becoming an effective tool for refined urban management. While conventional multi-rotor drones used for community inspections can improve inspection efficiency to some extent, they generally suffer from the following technical bottlenecks: when drones fly, the high-speed cutting of the air by the rotor generates significant aerodynamic noise, which can easily cause noise pollution when flying at low altitudes in residential areas, limiting their application time and scenarios.

[0004] In view of this, this solution was developed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a low-noise community inspection drone system based on a bladeless aerodynamic ring, which has no aerodynamic noise during flight.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a low-noise community inspection drone system based on a bladeless aerodynamic ring, including a drone body and a bladeless flight component. The drone body has at least two symmetrically arranged flight wings. An air passage hole is formed on the flight wing. An air passage ring is formed inside the air passage hole. An annular air passage gap is formed between the air passage ring and the air passage hole.

[0007] The bladeless flight component is connected to the lower part of the UAV body and the air outlet is located inside the air passage. The horizontal height of the air outlet of the bladeless flight component is lower than the highest horizontal height of the air passage. The bladeless flight component draws air into the annular air passage gap.

[0008] Furthermore, the drone body has four flight wings, which are arranged in a matrix and symmetrically in pairs.

[0009] Furthermore, the bladeless flight component includes multiple sets of air outlets, each set of air outlets corresponding to multiple air vents;

[0010] The air outlet component includes a base, an impeller, a first motor, and an air guide seat. A first mounting groove is formed on the upper surface of the base. The impeller is installed in the first mounting groove. The first motor is located above the impeller and drives the impeller to rotate. The air guide seat is connected to the opening of the first mounting groove. An air inlet is formed on the circumferential surface of the base. The air inlet is connected to the first mounting groove.

[0011] Furthermore, an upper cover ring is provided at the opening of the first mounting groove, and the upper cover ring is used to press and limit the air guide seat.

[0012] Furthermore, the base and the lower center of the flight body are connected by a connecting arm.

[0013] Furthermore, a support leg is also provided below the base.

[0014] Furthermore, it also includes a vision component, which is connected to the lower center of the drone body;

[0015] The vision component includes a rotating motor, a camera, and a camera housing. The rotating motor is located at the lower center of the drone body, and its output end is connected to the center of the upper surface of the camera. The camera housing is fitted onto the outer periphery of the camera.

[0016] Furthermore, the camera housing and the camera are fixed together by a retaining ring.

[0017] Furthermore, the vision component includes a protective cover that houses the rotating motor, camera, and camera housing and is detachably connected to the drone body.

[0018] Furthermore, the camera includes a mounting base, the horizontal cross-section of which is polygonal, and a camera head is provided on each side of the mounting base.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In this invention, the bladeless flight component draws in a large volume of air at a flow rate of 5.28 gallons per second. The air is pressurized and forced out through the annular air passage gap. The airflow causes pressure changes, generating wind. The speed of the resulting jet stream is 14 times higher than the speed of the inhaled air. With this configuration, the bladeless flight component eliminates aerodynamic noise during flight. Furthermore, the combination of the annular air passage gap and the bladeless flight component provides the drone with more power, enabling it to perform inspections in adverse weather conditions and preventing drone crashes due to blade damage.

[0026] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0027] like Figures 1-4 As shown, this embodiment provides a low-noise community inspection drone system based on a bladeless aerodynamic ring, including a drone body 1, a bladeless flight component 2, and a vision component 3.

[0028] The drone body 1 has four flight wings 11. From a top-down perspective, the drone body consists of a central body and elliptical shells located on both sides of the central body. The four flight wings 11 are located at the ends of the elliptical shells. In this embodiment, the four flight wings 11 are arranged in a matrix and symmetrically in pairs. Air passage holes 111 are formed on the flight wings 11. The opening of the air passage hole 111 is formed with a conical flare. An air passage ring 112 is formed inside the air passage hole 111. The air passage ring 112 is connected to the inner wall of the air passage hole 111 through a connecting plate. An annular air passage gap 113 is formed between the air passage ring 112 and the air passage hole 111. This annular air passage gap 113 structure can guide the airflow to concentrate and spray out evenly, enhance aerodynamic efficiency, and avoid the safety hazards caused by the traditional exposed rotor.

[0029] The bladeless flight component 2 is connected below the UAV body 1, with its air outlet located within the air passage 111. The horizontal height of the air outlet of the bladeless flight component 2 is lower than the highest horizontal height of the air passage 111. The bladeless flight component 2 draws air into the annular air passage 113. The bladeless flight component 2 is responsible for drawing in external air and delivering it into the annular air passage 113 (Coanda effect), achieving bladeless propulsion and fundamentally eliminating rotor noise. Specifically, the bladeless flight component 2 includes four sets of air outlets, each corresponding to one of the four air passages 111, enabling independent control and power distribution.

[0030] The air outlet component includes a base 21, an impeller 22, a first motor 23, a cover ring 24, and an air guide seat 25. A first mounting groove is formed on the upper surface of the base 21, and the impeller 22 is installed within this groove. In this design, the impeller 22 includes an impeller body and a conical mounting housing. The first motor 23 is positioned above the impeller 22 and drives it to rotate. The air guide seat 25 is connected to the opening of the first mounting groove. Specifically, a cover ring 24 is provided at the opening of the first mounting groove. The cover ring 24 is used to press and limit the air guide seat 25, ensuring accurate airflow guidance and a good seal. An air inlet is formed on the circumferential surface of the base 21, and the air inlet communicates with the first mounting groove.

[0031] The base 21 and the lower center of the flight body are connected by a connecting arm 212.

[0032] Preferably, a support leg 211 is also provided below the base 21. The support leg 211 is used to raise the height of the drone body 1 when the drone is parked, so as to avoid damage caused by the parts contacting the ground.

[0033] The vision component 3 is connected to the lower center of the drone body 1. The vision component 3 includes a rotating motor 31, a camera 32, a protective cover 33, and a camera housing 34. The rotating motor 31 is located in the lower center of the drone body 1. The output end of the rotating motor 31 is connected to the middle of the upper surface of the camera 32. The camera 32 includes a mounting base. The horizontal cross-sectional projection of the mounting base is polygonal, either hexagonal or quadrilateral. In this embodiment, a hexagonal mounting base is used. Each side of the mounting base is provided with a camera head. The camera housing 34 is fitted onto the outer periphery of the camera 32. The camera housing 34 and the camera 32 are fixed together by a fixing ring 36. A base plate 35 is also provided between the bottom surface of the camera 32 and the bottom surface of the inner cavity of the camera housing 34. The protective cover 33 covers the rotating motor 31, the camera 32, and the camera housing 34 and is detachably connected to the drone body 1. It can be connected by snap-fit ​​or screws. The design of the protective cover 33 not only effectively prevents dust and water but also facilitates daily maintenance and component replacement.

[0034] The vision component 3 drives the mounting base to rotate via the rotating motor 31, allowing multiple camera heads to rotate 360° to adapt to different environments.

[0035] In this design, the bladeless flight component 2 draws in a large volume of air at a flow rate of 5.28 gallons per second. The air is pressurized and forced out through the annular air passage 113. The airflow causes pressure changes, generating wind. The speed of the resulting jet stream is 14 times higher than the speed of the inhaled air. With this configuration, the bladeless flight component 2 does not generate aerodynamic noise during flight. Furthermore, through the cooperation between the annular air passage 113 and the bladeless flight component 2, the drone in this design has more power, enabling it to perform inspections in adverse weather conditions and preventing drone crashes due to blade damage.

[0036] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
