Description

Technical Field

[0001] This invention mainly relates to the field of power transmission line inspection technology, and specifically to a drone inspection device for power transmission lines. Background Technology

[0002] Transmission lines are a crucial component of the power system. With rapid economic development, the number of transmission lines is increasing. The operational status inspection of overhead line corridors is vital for the safe, stable, and reliable operation of power lines, and is of paramount importance to power supply reliability, the safety of power supply companies, and their economic efficiency. Because transmission lines span large distances, often hundreds of kilometers, previous inspections primarily involved dividing areas and conducting manual inspections. This method required workers to climb utility poles, posing certain risks, and was relatively inefficient, failing to meet the requirements for efficient and rapid transmission line inspections.

[0003] Chinese invention patent CN111509616A discloses a drone inspection device for power transmission lines. The device includes a drone body with an inspection unit mounted below it. A camera is mounted below the inspection unit, and a wireless video transmission antenna is mounted above it. The inspection unit also contains a controller electrically connected to the camera, a BeiDou positioning module, and an image acquisition module. The drone body houses a flight control module, a navigation module, and a power supply module. This drone inspection device, through aerial inspection, not only reduces the workload and danger for operators but also significantly improves the flexibility and coverage of inspections, thereby significantly improving the quality and efficiency of power transmission line inspections.

Detailed Implementation

[0027] The present invention will be further described below with reference to specific embodiments. The invention is explained through illustrative embodiments and descriptions, but is not intended to limit the invention.

[0028] Example 1: As Figures 1-11The UAV inspection device for power transmission lines shown includes a detection mechanism 1, a positioning marking mechanism 2, a spraying mechanism 3, and a body 4. The detection mechanism 1 includes a detection motor 101 and an inductor central shaft 104. The positioning marking mechanism 2 includes a translation motor 201. The spraying mechanism 3 includes a spraying source 301 and a rotation motor 304. The detection motor 101, translation motor 201, spraying source 301, and rotation motor 304 are fixedly mounted on the body 4, and the inductor central shaft 104 is rotatably mounted on the body 4.

[0029] The rotating drive gear 102 of the detection mechanism 1 is fixedly mounted on the rotating shaft of the detection motor 101. The rotating drive gear 102 meshes with the rotating driven gear 103. The rotating driven gear 103 is located in the middle of the inductor central shaft 104. Inductor side rods 105 are fixedly mounted at both ends of the inductor central shaft 104. The closed drive gear 106 is fixedly mounted on the machine body 4. The closed drive gear 106 meshes with the closed driven gear 107. The closed driven gear 107 is fixedly mounted at one end of the intermediate transmission shaft 108. The other end of the intermediate transmission shaft 108... One end is fixedly provided with a detection active bevel gear 109, and the intermediate transmission shaft 108 is rotatably provided on the inductor side rod 105. The detection active bevel gear 109 and the detection passive bevel gear 110 form a gear mesh. The detection passive bevel gear 110 is fixedly provided on one end of the closed long shaft 111. The closed long shaft 111 is rotatably provided on the inductor side rod 105. The other end of the closed long shaft 111 is provided on the inductor bottom rod 112. The end of the inductor bottom rod 112 is slidably provided with a closing contact 114. The two ends of the closing spring 113 are respectively connected to the inductor bottom rod 112 and the closing contact 114.

[0030] When in standby mode, the inductor side rod 105 is horizontally positioned in the bottom groove of the body 4, and the inductor bottom rod 112 is vertically positioned in the groove of the body 4.

[0031] Specifically, the detection motor 101 provides power to drive the rotating drive gear 102 to rotate, which in turn drives the rotating driven gear 103 to rotate, thereby causing the inductor central shaft 104 to rotate. The inductor side rod 105 then rotates from a horizontal to a vertical position. During the rotation of the inductor side rod 105, the closed drive gear 106 drives the closed driven gear 107 to rotate, and simultaneously, through the intermediate transmission shaft 108 and...

[0032] The driving power of the active bevel gear 109 is detected, causing the closed long shaft 111 to rotate. As a result, the inductor base rod 112 rotates 90 degrees relative to the inductor side rod 105. Therefore, the two inductor base rods 112 are on the same straight line, and under the action of the closing spring 113, the two closed contacts 114 touch each other.

[0033] In operation, the inductor central shaft 104, the two inductor side rods 105, the two inductor bottom rods 112, and the two closed contacts 114 are equipped with coils. When closed, they form an induction coil, which is used to sense the magnitude of the current in the power transmission cable 5, thereby checking the working status of the power transmission cable 5.

[0034] A temperature sensing strip 115 is fixedly installed on the side of the inductor side rod 105. The temperature sensing strip 115 is used to measure temperature.

[0035] Specifically, when the resistance of a part of the power transmission cable 5 increases due to damage or other reasons, the local temperature will rise suddenly. After the temperature sensor strip 115 detects the sudden rise in temperature, the location of the fault in the power transmission cable 5 can be determined.

[0036] The positioning marking mechanism 2 includes a pick-and-place mechanism. The support frame 203 of the pick-and-place mechanism is slidably mounted on the machine body 4, and the support frame 203 and the lead screw 202 form a threaded engagement. The lead screw 202 is fixedly mounted on the rotating shaft of the translation motor 201. The pick-and-place cylinder 204 is fixedly mounted on the support frame 203. The telescopic shaft of the pick-and-place cylinder 204 is provided with a pick-and-place end 205. The two brackets of the pick-and-place end 205 are slidably mounted with pick-and-place sliding rods 206. The end of the pick-and-place sliding rods 206 is provided with pick-and-place inclined blocks 207. The two ends of the pick-and-place motor 208 are fixedly connected to the pick-and-place end 205 and the pick-and-place inclined blocks 207, respectively.

[0037] The positioning marking mechanism 2 includes a positioning mechanism that is slidably mounted on the body 4. The positioning frame 209 of the positioning mechanism contains a positioning chip. Optionally, the positioning chip is a Beidou satellite system chip. The top of the positioning frame 209 is provided with a support boss 210. The top of the support boss 210 is provided with an upper inclined block 211, and the middle of the support boss 210 is slidably provided with a lower inclined block 212.

[0038] Specifically, the translation motor 201 provides power to drive the lead screw 202 to rotate, thereby driving the support frame 203 to translate; the telescopic shaft of the take-up and discharge cylinder 204 descends, and when the inclined surface of the take-up and discharge block 207 touches the inclined surface of the upper inclined block 211, the take-up and discharge block 207 retracts into the take-up and discharge end 205, and the take-up and discharge machine 208 compresses it. When the take-up and discharge block 207 passes the upper inclined block 211, due to the action of the take-up and discharge machine 208, the take-up and discharge block 207 jams the upper inclined block 211, that is, the take-up and discharge machine... The positioning mechanism is locked in place; the telescopic shaft of the discharge cylinder 204 continues to descend, the inclined surface of the discharge block 207 acts on the inclined surface of the lower inclined block 212, the discharge block 207 passes through the lower inclined block 212, then the telescopic shaft of the discharge cylinder 204 rises, the discharge block 207 contacts the inclined surface of the lower inclined block 212, the discharge block 207 can then pass through the lower inclined block 212 and the upper inclined block 211, that is, the discharge mechanism is disengaged from the positioning mechanism, and the lower inclined block 212 returns to the standby state under the action of gravity.

[0039] The positioning frame 209 of the positioning mechanism is equipped with a tactile cylinder 213. The telescopic shaft of the tactile cylinder 213 is adapted to the circular hole of the power rack 214. The power rack 214 is slidably mounted on the positioning frame 209. A pressure sensing block 216 is provided at the bottom of the power rack 214. The two ends of the power spring 215 are fixedly connected to the positioning frame 209 and the pressure sensing block 216, respectively. The power rack 214 and the positioning center gear 217 form a gear mesh. The positioning center gear 217 is fixedly mounted on the positioning center shaft 218. The positioning center shaft 218 is rotatably mounted on the positioning frame 209. A reset driven bevel gear 219 is provided on the positioning center shaft 218. The reset driven bevel gear 219 and the reset driving bevel gear 220 form a gear mesh. The reset driving bevel gear 220 is fixedly mounted on the reset transmission shaft 218. One end of the reset transmission shaft 221 is rotatably mounted on the positioning frame 209, and the other end of the reset transmission shaft 221 is fixedly mounted on the reset gear 222. The reset gear 222 and the reset rack 223 form a gear mesh. The reset rack 223 is slidably mounted on the positioning frame 209. The end of the reset rack 223 is provided with a reset plate 224. The end of the positioning center shaft 218 is provided with the input end of the transmission gear set 225 and the transmission belt 227 in sequence. Optionally, the transmission gear set 225 is composed of four gears meshing in sequence. The output end of the transmission gear set 225 is located on the central shaft of the clamping jaw 1 226, and the output end of the transmission belt 227 is located on the central shaft of the clamping jaw 228. The central shafts of the clamping jaw 1 226 and the clamping jaw 228 are rotatably mounted on the positioning frame 209.

[0040] Specifically, after the positioning mechanism descends, the pressure sensing block 216 touches the power transmission cable 5. Sensing the pressure, the pressure sensing block 216 retracts the retraction shaft of the electric cylinder 213. Driven by the power spring 215, the pressure sensing block 216 moves downward relative to the positioning frame 209. Power is transmitted through the positioning center gear 217, causing the positioning center shaft 218 to rotate clockwise. This power is then transmitted through the transmission gear set 225 and the transmission belt 227, causing the clamping jaws 226 and 228 to simultaneously move towards the positioning frame 209. The power transmission cable 5 is rotated to clamp it; the reset plate 224 is pulled to move the reset rack 223, which transmits power through the reset gear 222, causing the reset transmission shaft 221 to rotate. Then, the power is transmitted through the reset drive bevel gear 220 and the reset transmission shaft 221 to reverse the positioning center shaft 218. Then, the power is transmitted through the transmission gear set 225 and the transmission belt 227 respectively, causing the clamping claw 1 226 and clamping claw 228 to rotate away from the power transmission cable 5 at the same time, thus releasing the power transmission cable 5.

[0041] The spraying mechanism 3 also includes a central rotating head 302. The inlet of the central rotating head 302 is connected to the spraying source 301, and the outlet of the central rotating head 302 is rotatably connected to the inlet of the rotating tube 303. The rotating tube 303 is rotatably mounted on the machine body 4. The middle part of the rotating tube 303 is connected to one end of the power belt 305, and the other end of the power belt 305 is connected to the rotating shaft of the rotating motor 304. The outlet of the rotating tube 303 is rotatably connected to the inlet of the horizontal rotating tube 306, and the outlet of the horizontal rotating tube 306 is connected to the spray head 307.

[0042] The spraying mechanism 3 also includes a fixed wheel 308, which is fixedly mounted on the machine body 4. One end of the translation belt 309 is connected to the fixed wheel 308, and the other end of the translation belt 309 is connected to the rotating wheel 310. The rotating wheel 310 is fixedly connected to the horizontal rotating pipe 306.

[0043] When in standby mode, the horizontal rotating pipe 306 and the nozzle 307 are located in the bottom groove of the body 4.

[0044] Specifically, the spray source 301 provides paint, which is sprayed through the rotating head 302, rotating tube 303, horizontal rotating tube 306, and spray head 307. The rotating motor 304 provides power to make the rotating tube 303 rotate. Since the fixed wheel 308 is fixed, the horizontal rotating tube 306 also rotates relative to the rotating tube 303 while the rotating tube 303 is rotating. That is, the spray head 307 always remains horizontal. The spray head 307 is long and can increase the spraying length.

[0045] After the positioning device is recovered, the power transmission cable 5 is permanently marked using the spraying mechanism 3.

[0046] Working principle: When in standby mode, the inductor side rod 105, the flat rotating tube 306 and the nozzle 307 are horizontally arranged in the bottom groove of the body 4, and the inductor bottom rod 112 is vertically arranged in the groove of the body 4.

[0047] In operation, the machine body 4 is launched from the ground and placed above the power transmission cable 5. The detection motor 101 provides power to drive the rotating drive gear 102 to rotate, which in turn drives the rotating driven gear 103 to rotate, thereby causing the inductor central shaft 104 to rotate. The inductor side rod 105 then rotates from a horizontal state to a vertical state. During the rotation of the inductor side rod 105, the closed drive gear 106 drives the closed driven gear 107 to rotate. At the same time, the power is transmitted through the intermediate transmission shaft 108 and the detection drive bevel gear 109, causing the closed long shaft 111 to rotate. Therefore, the inductor bottom rod 112 rotates 90 degrees relative to the inductor side rod 105. Thus, the two inductor bottom rods 112 are on the same straight line, and under the action of the closing spring 113, the two closed contacts 114 touch each other.

[0048] The induction coil senses the current in the power transmission cable 5 to check its working status. At the same time, the machine body 4 patrols along the power transmission cable 5. When the temperature sensor strip 115 detects a sudden rise in temperature, the location of the fault in the power transmission cable 5 can be determined, and the machine body 4 then hovers in the air.

[0049] The translation motor 201 provides power to drive the lead screw 202 to rotate, thereby driving the support frame 203 to translate, causing the dispensing cylinder 204 to move above the positioning mechanism. The telescopic shaft of the dispensing cylinder 204 descends. When the inclined surface of the dispensing block 207 touches the inclined surface of the upper inclined block 211, the dispensing block 207 retracts into the dispensing end 205, and the dispensing motor 208 compresses. After the dispensing block 207 passes the upper inclined block 211, due to the action of the dispensing motor 208, the dispensing block 207 jams the upper inclined block 211, that is, the dispensing mechanism jams the positioning mechanism. The dispensing mechanism moves the positioning mechanism, causing the positioning mechanism to disengage from the machine body 4. The telescopic shaft of the dispensing cylinder 204 descends, bringing the positioning mechanism down with it. The pressure sensing block 216 touches the power cable 5. The pressure sensing block 216 senses the pressure, and the retraction shaft of the touch-sensitive cylinder 213 retracts. Driven by the power spring 215, the pressure sensing block 216 moves downward relative to the positioning frame 209, transmitting power through the positioning center gear 217 to make the positioning center shaft 218 rotate clockwise. Then, the power is transmitted through the transmission gear set 225 and the transmission belt 227 respectively, causing the clamping claw 1 226 and clamping claw 228 to rotate simultaneously toward the power transmission cable 5, clamping the power transmission cable 5. The telescopic shaft of the take-off and discharge cylinder 204 continues to descend, and the inclined surface of the take-off and discharge inclined block 207 acts on the lower inclined block 212. The take-off and discharge inclined block 207 passes through the lower inclined block 212. Then, the telescopic shaft of the take-off and discharge cylinder 204 rises, and the take-off and discharge inclined block 207 contacts the inclined surface of the lower inclined block 212. The take-off and discharge inclined block 207 can then pass through the lower inclined block 212 and the upper inclined block 211, that is, the take-off and discharge mechanism disengages from the positioning mechanism, and the lower inclined block 212 returns to the standby state under the action of gravity.

[0050] The spray source 301 provides paint, which is sprayed through the intermediate rotating head 302, rotating tube 303, horizontal rotating tube 306 and spray head 307. The rotating motor 304 provides power to make the rotating tube 303 rotate. Since the fixed wheel 308 is fixed, the horizontal rotating tube 306 also rotates relative to the rotating tube 303 while the rotating tube 303 is rotating. That is, the spray head 307 always remains horizontal. The spray head 307 is long and can increase the spraying length.

[0051] After locating the positioning mechanism through the positioning system, the staff pulls the reset plate 224 to move the reset rack 223 horizontally, which transmits power through the reset gear 222, causing the reset transmission shaft 221 to rotate. Then, through the reset drive bevel gear 220 and the reset transmission shaft 221, the power is transmitted to reverse the positioning center shaft 218. Then, through the transmission gear set 225 and the transmission belt 227, the power is transmitted to make the clamping jaw 1 226 and clamping jaw 228 rotate away from the power transmission cable 5 at the same time, releasing the power transmission cable 5 and thus retrieving the positioning mechanism.

[0052] Any aspects not covered in this invention are applicable to existing technologies.
