Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a high-efficiency anti-collision structure for use in power line inspection UAVs. Background Technology

[0002] Drones are short for unmanned aerial vehicles. They are unmanned aircraft controlled by radio remote control equipment and onboard program control devices. Compared with manned aircraft, drones can adapt to more tasks and have a wide range of applications, which can be divided into military and civilian uses. They can be used in aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news reporting, power line inspection, disaster relief, film and television shooting, and romantic creation, greatly expanding the uses of drones. In power line inspection, drones are needed to observe the equipment more clearly. To ensure the safety of drones, anti-collision structures are required.

[0003] A search revealed Chinese patent CN217022870U, which discloses a drone anti-collision structure. The structure includes a drone body, a support frame at the bottom of the drone body, a mounting frame at the bottom of the drone body, a camera at the bottom of the mounting frame, a dustproof device on the front of the mounting frame, and an anti-collision device on the side of the drone body. The anti-collision device includes a mounting plate, a mounting block, an anti-collision frame, an anti-collision plate, bolts, a spring shock absorber, an anti-collision baffle, a sponge pad, and threaded holes. The mounting plate is fixedly connected to the side of the drone body, and the mounting block is fixedly connected to the bottom of the mounting plate. This drone anti-collision structure, by incorporating the anti-collision device, with the anti-collision plate and anti-collision frame providing necessary and reliable anti-collision measures on the upper and lower sides of the rotor, makes the drone less susceptible to damage from strong impacts. The drone rotor is less likely to be damaged, maintaining normal operation and not affecting the drone's use.

[0004] In this patent, the anti-collision structure can only be fixed to the outer edge of the propeller to protect the drone from collisions. The structures on each propeller are used independently, which can easily lead to snagging during use. Furthermore, it cannot provide cushioning protection for the drone when it lands, so it has limited functionality. In addition, each structure requires a large number of bolts, making the disassembly and assembly process cumbersome and not conducive to quick assembly and disassembly. Utility Model Content

[0027] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0028] To address the problems existing in the background technology, this application proposes the following technical solution: a high-efficiency anti-collision structure for use in power line inspection drones.

[0029] The specific technical solution includes a connecting shell 1, a liftable anti-collision component 2, and a sleeve 3;

[0030] like Figure 1-4 As shown, the liftable anti-collision component 2 is installed below the connecting shell 1. The liftable anti-collision component 2 is used to protect the drone from collisions. The liftable anti-collision component 2 includes a fixed block 201 located directly below the connecting shell 1, a telescopic rod 202 symmetrically installed below the connecting shell 1, and a push rod 203. The fixed block 201 can limit and support the fixed end of the telescopic rod 202. The telescopic rod 202 can drive the anti-collision ring 204 to rise and fall. The push rod 203 can provide pushing and pulling forces to the fixed end of the telescopic rod 202. The fixed end of the telescopic rod 202 is rotatably connected to the fixed block 201, and the telescopic end is provided with the anti-collision ring. 204. The anti-collision ring 204 can protect the drone from collisions. The push rod 203 is fixedly installed below the fixed block 201 and the telescopic end is symmetrically equipped with a pull rod 205. The fixed end of the telescopic rod 202 is fixedly equipped with a pull ring 206 sleeved on the outside of the pull rod 205. The pull rod 205 can pull the telescopic rod 202 through the pull ring 206. The sleeve 3 passes through the lower part of the connecting shell 1 and is sleeved on the outside of the fixed block 201. The sleeve 3 can limit the fixed block 201. The sleeve 3 is fixedly installed inside the sleeve 3 and is located above the fixed block 201. The spring 4 can buffer the fixed block 201.

[0031] When the drone is in flight, the anti-collision ring 204 is located on the outer edge of the propeller 12, providing anti-collision and anti-snagging protection for the drone. When the drone needs to land, before it touches the ground, the telescopic rod 202 is retracted. The fixed end of the telescopic rod 202 is limited by the fixing block 201 and cannot move. The fixed end of the telescopic rod 202 can only rotate around its axis around the step connected to the fixing block 201. The telescopic end of the telescopic rod 202 is protected by the anti-collision ring 204. 4. Limiting the movement: The shape of the anti-collision ring 204 remains unchanged, and the horizontal distance between the telescopic end of the telescopic rod 202 and the center of the anti-collision ring 204 cannot change. When the telescopic rod 202 retracts, it exerts a downward pulling force on the anti-collision ring 204. The telescopic end of the telescopic rod 202 descends and rotates with the anti-collision ring 204. The telescopic end of the telescopic rod 202 drives the anti-collision ring 204 to descend. When the telescopic rod 202 is in a horizontal state, the telescopic rod 202 and the anti-collision ring 204 are at a certain distance. Within the same plane, the telescopic rod 202 can only exert centripetal and centrifugal forces on the anti-collision ring 204. The anti-collision ring 204 cannot rise or fall. By activating the push rod 203, the push rod 203 retracts, causing the pull rod 205 to rise. The pull rod 205 then causes the pull ring 206 to rise, and the pull ring 206 exerts an upward pulling force on the fixed end of the telescopic rod 202. At this time, the telescopic rod 202 can rotate around the central axis of the part connected to the fixed block 201. The telescopic rod 202 is subjected to a downward force. By activating the telescopic rod 202... The telescopic rod 202 extends to push the anti-collision ring 204 downward, causing the anti-collision ring 204 to descend. When the drone lands, the anti-collision ring 204 impacts the ground. The impact force on the anti-collision ring 204 is transmitted to the fixed block 201 through the telescopic rod 202. The force on the fixed block 201 is transmitted to the spring 4, which can buffer the impact force. After the impact force is reduced, it is transmitted to the sleeve 3, which in turn transmits it to the connecting shell 1. The connecting shell 1 experiences a smaller force, which can protect the drone upon landing.

[0032] like Figure 5 As shown, the connecting shell 1 has an internal thread 5, and the sleeve 3 has an external thread 6 that is threaded to the internal thread 5. The connection between the internal thread 5 and the external thread 6 can drive the connection between the connecting shell 1 and the sleeve 3. When the sleeve 3 is inserted into the connecting shell 1, the external thread 6 is rotated by turning the sleeve 3. The external thread 6 is threaded to the internal thread 5, which can quickly install the sleeve 3. The fixed sleeve 3 can also fix the liftable anti-collision component 2, which can also quickly install the liftable anti-collision component 2. By turning the sleeve 3 in the opposite direction, the sleeve 3 drives the external thread 6 to rotate in the opposite direction, and the external thread 6 is separated from the internal thread 5, which can quickly disassemble the sleeve 3 and the liftable anti-collision component 2 connected to it.

[0033] like Figure 5As shown, a limiting piece 7 is inserted below the connecting shell 1, and a limiting ring 8 is fixedly installed on the outer side wall of the sleeve 3, which is sleeved outside the limiting piece 7. After the sleeve 3 is installed, the end of the limiting piece 7 connected to the connecting shell 1 is inserted into the limiting ring 8. After the limiting piece 7 is fixed by the connecting shell 1, it fixes the limiting ring 8. The limiting ring 8 fixes the sleeve 3, which can prevent the sleeve 3 from rotating and causing the external thread 6 to disengage from the internal thread 5, thereby increasing the stability of the sleeve 3 and thus increasing the stability of the liftable anti-collision component 2.

[0034] like Figure 5 As shown, the top of the fixing block 201 is fixedly equipped with a top plate 9 that passes through the sleeve 3. The top plate 9 can limit the fixing block 201 and prevent the fixing block 201 from falling off the sleeve 3.

[0035] like Figure 1-2 and Figure 5 As shown, the top of the connecting shell 1 is fixedly equipped with the body 10, the side wall of the body 10 is fixedly equipped with the wing 11, and the port of the wing 11 is fixedly equipped with the propeller 12. The propeller 12 is controlled to rotate through the control panel. The propeller 12 drives the body 10 to rise through the wing 11, which can drive the drone to fly.

[0036] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
