Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology and relates to a portable inspection UAV. Background Technology

[0002] Inspection drones are unmanned aerial vehicles equipped with high-definition cameras, infrared thermal imagers, and other equipment. They are mainly used to replace manual labor in inspection and testing in various scenarios. They can overcome terrain, environmental, and spatial limitations, quickly cover areas such as power lines, oil and gas pipelines, bridges and tunnels, mines, farmland, and forests, and transmit image data in real time to accurately identify equipment failures, safety hazards, environmental anomalies, and other problems. They not only significantly improve inspection efficiency and reduce labor costs and operational risks, but also assist in subsequent maintenance decisions through data retention and analysis. They are widely used in multiple fields such as power, energy, infrastructure, security, and agriculture.

[0003] For example, patent (CN213735547U) discloses an inspection drone, which describes a drone body. A shock-absorbing device is fixedly connected to the lower surface of the drone body, and a high-definition camera is movably connected to the lower surface of the shock-absorbing device. A tripod is fixedly connected to the lower surface of the drone body near its edge. A bracket is fixedly connected to one side of the drone body, and a motor is fixedly connected to the upper surface of the bracket. A propeller protection ring is fixedly connected to the surface of the motor, and a propeller is movably connected to the upper surface of the motor inside the propeller protection ring. A circuit board is fixedly connected to the lower internal surface of the drone body, and a ceramic plate is fixedly connected above the circuit board inside the drone body. This inspection drone can protect the drone's propeller from being touched by objects during flight, allowing the drone to perform better inspections in humid or high-temperature environments.

[0004] When using the above technology, the following technical problems were found in the prior art: After the device is used up, the bracket and propeller of the device cannot be folded and stored, so when the user carries it, the bracket and propeller can only be directly exposed. This not only makes it easy for the device to accidentally touch external objects, but also causes damage to the bracket and propeller, affecting the subsequent use of the device. Utility Model Content

[0005] The technical problem this invention aims to solve is that after the device is used up, the bracket and propeller cannot be folded and stored, causing them to be directly exposed when the user carries it. This not only makes it easy for the device to accidentally come into contact with external objects, but also causes damage to the bracket and propeller, affecting the subsequent use of the device.

[0006] The present invention discloses a portable inspection drone, comprising a drone body, with a first gear and a second gear respectively provided at both ends of the inner side of the drone body. A support arm is fixedly connected to the ends of the first gear and the second gear that are far apart from each other. The first gear and the second gear are meshed together. A rotating propeller is provided at the end of the support arm. A rotating shaft is fixedly connected to the upper end of the first gear and the second gear. The rotating shaft is rotatably connected to the drone body. A linkage component is provided on the inner side of the drone body.

[0007] The linkage component includes a gear column b, which is rotatably connected to the middle of the drone body. A double-sided rack is symmetrically arranged on the inner side of the drone body with the gear column b as the axis. The double-sided rack meshes with the gear column b. A gear column a is symmetrically arranged on the inner side of the drone body with the gear column b as the axis. The gear column a is located on the outer side of the rotating shaft and is fixedly connected to the rotating shaft. The gear column a meshes with the double-sided rack.

[0008] The lower end of the drone body is provided with a storage slot, and a lifting block is slidably connected to the inner side of the storage slot. A high-definition camera is provided at the lower end of the lifting block, and a threaded rod is fixedly connected to the upper end of the lifting block. The threaded rod is located inside the gear column b and is threadedly connected to the gear column b.

[0009] A servo motor is fixedly connected to the inside of the drone body.

[0010] Multiple limiting blocks are provided at the port of the storage slot, and the limiting blocks are fixedly connected to the drone body.

[0011] The inner side of the UAV body is symmetrically fixedly connected with a support plate, which is located inside the double-sided rack and is slidably connected to the double-sided rack.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the linkage component drives the gear column a to rotate, and the first gear and the second gear mesh and connect, so that multiple support arms drive the rotating propeller to be stored inside the drone body. At the same time, the high-definition camera is threadedly connected to the threaded rod, and the storage groove limits the rotation of the lifting block. So when the multiple support arms are unfolded, the lifting block drives the high-definition camera to move to the outside of the storage groove. When the multiple support arms are stored inside the drone body, the lifting block drives the high-definition camera to move to the inside of the storage groove, thereby avoiding the high-definition camera being exposed to the outside.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] Example 1 like Figure 1- Figure 6 As shown, a portable inspection drone includes a drone body 101. A first gear 102 and a second gear 103 are respectively provided at both ends of the inner side of the drone body 101. A support arm 104 is fixedly connected to the ends of the first gear 102 and the second gear 103 that are far apart from each other. The first gear 102 and the second gear 103 are meshed together. A rotary propeller 105 is provided at the end of the support arm 104. A rotating shaft 106 is fixedly connected to the upper end of the first gear 102 and the second gear 103. The rotating shaft 106 is rotatably connected to the drone body 101.

[0020] To enable the four support arms 104 to rotate simultaneously, a linkage assembly is provided on the inner side of the drone body 101. The linkage assembly includes a gear column b203, which is rotatably connected to the middle of the drone body 101. A double-sided rack 202 is symmetrically arranged on the inner side of the drone body 101 with the gear column b203 as the axis. The double-sided rack 202 is meshed with the gear column b203. A gear column a201 is symmetrically arranged on the inner side of the drone body 101 with the gear column b203 as the axis. The gear column a201 is located on the outer side of the rotating shaft 106 and is fixedly connected to the rotating shaft 106. The gear column a201 is meshed with the double-sided rack 202.

[0021] In order to provide driving force for the second gear 103, a servo motor 401 is provided on the inner side of the UAV body 101, and the output end of the servo motor 401 is fixedly connected to the second gear 103.

[0022] To ensure greater stability during the lateral movement of the double-sided rack 202, a support plate 601 is symmetrically fixedly connected to the inner side of the UAV body 101. The support plate 601 is located inside the double-sided rack 202 and is slidably connected to the double-sided rack 202.

[0023] During operation, the servo motor 401 is started, and the output end of the servo motor 401 drives the second gear 103 to rotate. When the second gear 103 rotates, it meshes with the double-sided rack 202 through the gear column a201, so that the double-sided rack 202 slides on the outside of the support plate 601. Then, the two double-sided racks 202 mesh with the gear column b203, thereby driving the other double-sided rack 202 to move relative to each other. When the two double-sided racks 202 move relative to each other, they mesh with the gear column a201 and the first gear 102 meshes with the second gear 103, thereby driving the multiple support arms 104 to rotate. This causes the support arms 104 to drive the rotary propeller 105 to rotate to the inside of the UAV body 101, thus storing the support arms 104 and the rotary propeller 105 inside the UAV body 101.

[0024] Example 2 like Figure 2 - Figure 6 As shown, the lower end of the drone body 101 is provided with a storage slot 301, and a lifting block 302 is slidably connected to the inner side of the storage slot 301. A high-definition camera 303 is provided at the lower end of the lifting block 302, and a threaded rod 304 is fixedly connected to the upper end of the lifting block 302. The threaded rod 304 is located inside the gear column b203 and is threadedly connected to the gear column b203.

[0025] A servo motor 401 is provided on the inner side of the drone body 101, and the output end of the servo motor 401 is fixedly connected to the second gear 103.

[0026] Multiple limiting blocks 501 are provided at the port of the storage slot 301, and the limiting blocks 501 are fixedly connected to the drone body 101.

[0027] During operation, when the gear column b203 rotates, the gear column b203 is threadedly connected to the threaded rod 304, and the storage groove 301 limits the rotation of the lifting block 302, thereby causing the lifting block 302 to drive the high-definition camera 303 to move longitudinally. When the multiple support arms 104 are unfolded, the lifting block 302 drives the high-definition camera 303 to move to the outside of the storage groove 301. When the multiple support arms 104 are stored inside the drone body 101, the lifting block 302 drives the high-definition camera 303 to move to the inside of the storage groove 301, thereby preventing the high-definition camera 303 from being exposed to the outside.
