[0002] With the development of power technology, outdoor aerial cables are needed to facilitate the long-distance transmission and distribution of electricity. Outdoor aerial cables transmit electricity to various areas by hanging in the air, and then distribute it to residential, commercial and industrial electricity. Such cables are usually used in cities and industrial areas because they can effectively reduce the use of ground land, reduce environmental pollution, and improve the reliability and safety of the power system.

[0003] In order to improve the operating stability of outdoor cables, it is necessary to regularly inspect and maintain the cable surface. However, the current high-altitude cables, especially outdoor cables located in mountainous areas, are limited in their installation locations, resulting in high costs and difficulty for subsequent manual maintenance, and very limited safety. At the same time, the maintenance construction cycle is long, which results in the timeliness of inspection and maintenance being affected by the above factors.

[0004] Therefore, it is necessary to provide an outdoor high-altitude cable detection device with a sky-through data transmission network to solve the above problems. Summary of the invention

[0037] Figure 1 , Figure 2 , Figure 3 and Figure 4 An outdoor high-altitude cable detection device with a Tiantong data transmission network is shown, including a drone body 1 with an airborne Tiantong satellite communication system, side flip assembly grooves 2 are provided on both side walls of the drone body 1, an electrically controlled flip adjustment mechanism 3 is movably installed inside the side flip assembly groove 2, an electrically controlled lifting arm 4 is movably installed inside the electrically controlled flip adjustment mechanism 3, an electrically controlled top driving wheel 5 is movably installed on the inner top surface of the electrically controlled lifting arm 4, and a visual sensor probe 6, an optical ranging probe 7 and an optical detection unit 8 are installed on the upper surface of the drone body 1.

[0038] Working principle: People remotely control the take-off and landing of the drone body 1, and then drive the detection equipment to move directly below one end of the cable. The visual sensor probe 6 can visually observe the position of all cables, and then the optical ranging probe 7 uses laser monitoring to accurately measure the position and distance of the cable directly above, so as to accurately cooperate with the drone body 1 for positioning, so that it can hover directly below the cable to be detected. Then, after the positioning is determined, the electric-controlled flip adjustment mechanism 3 on both sides is started to flip upward, and the electric-controlled top drive wheel 5 on the inner top surface of the electric-controlled lifting arm 4 is transferred to the cable directly above. Then the electric-controlled lifting arm 4 descends, controls the electric-controlled top drive wheel 5 to descend to the upper surface of the cable, and then closes the drone body 1, and then cooperates with the optical ranging probe 7 to perform distance detection. When the cable moves to the center position of the optical detection unit 8, the electric-controlled lifting arm 4 stops descending, and then the electric-controlled top drive wheel 5 drives the entire device to translate, and then the optical detection unit 8 starts to rotate at the same time to perform surrounding detection on the periphery of the cable. The airborne Tiantong satellite communication system will then transmit a detection signal via satellite, so that text signals can be sent by receiving satellite communication signals in the absence of base station signals. The principle is the same as that of mobile phone satellite communication.

[0039] In order to cooperate with the bottom support and limitation, the upper surface of the drone body 1 is movably equipped with a bottom guide limiting wheel 9 that cooperates with the electrically controlled top driving wheel 5.

[0040] When the electrically-controlled lifting arm 4 descends to the lowest position, the lower end of the electrically-controlled top driving wheel 5 is supported on the upper end of the cable, while the upper end of the bottom guide limiting wheel 9 is supported on the lower end of the cable, thereby improving the stability and guidance during the translation process.

[0041] Arc-shaped limiting grooves are provided on the outer arc-shaped surfaces of the electrically controlled top driving wheel 5 and the bottom guide limiting wheel 9, which can improve their fit with the cable surface and lateral limiting performance.

[0042] In order to cooperate with the flip adjustment, the electrically controlled flip adjustment mechanism 3 includes a flip adjustment cylinder 31 movably installed in the lateral flip assembly groove 2 through two side shafts and a side electrically controlled support rod 32 for controlling the flip adjustment cylinder 31 .

[0043] The side-mounted electric control support rod 32 controls the turning adjustment of the turning adjustment cylinder 31 in the lateral turning assembly groove 2 by telescoping.

[0044] In order to cooperate with the lifting and lowering adjustment, the electrically-controlled lifting arm 4 includes a control motor 41 installed inside the UAV body 1, an internal threaded adjustment cylinder 42 movably installed inside the flip adjustment cylinder 31, an external threaded lifting tube 43 threadedly inserted into the internal threaded adjustment tube 42, and an N-shaped top assembly frame 44 axially fixed at the top of the external threaded lifting tube 43.

[0045] In order to cooperate with the meshing drive, a first transmission gear 10 is axially mounted on the upper end of the outer side of the internal thread adjustment cylinder 42 , and second transmission gears 11 that cooperate with the first transmission gear 10 are axially mounted on both sides of the control motor 41 .

[0046] When the side-mounted electric control support rod 32 controls the upper end of the flip adjustment cylinder 31 to flip inward by contraction, the first transmission gear 10 at the upper end of the outer side of the internal thread adjustment cylinder 42 will eventually engage with the second transmission gear 11, and then the control motor 41 drives the second transmission gear 11 to rotate, thereby controlling the rotation of the internal thread adjustment cylinder 42. The rotation of the internal thread adjustment cylinder 42 can drive the external thread lifting tube 43 to be lifted and lowered along the internal thread adjustment cylinder 42.

[0047] In order to cooperate with lateral limiting and lifting guidance, a strip-shaped limiting opening 12 is opened on the side wall of the external threaded lifting tube 43, and an internal limiting block 13 protruding into the strip-shaped limiting opening 12 is provided on the inner side surface of the flip adjustment cylinder 31.

[0048] In order to cooperate with lateral assembly and gravity monitoring, the two side walls of the top assembly frame 44 are provided with lateral assembly seats 14 for installing the electrically controlled top drive wheel 5, and a gravity sensor module 15 is arranged inside the lateral assembly seat 14 at the assembly end of the electrically controlled top drive wheel 5.

[0049] The assembly shafts on both sides of the electric-controlled top driving wheel 5 are inserted into the lateral assembly seats 14 and contact the gravity sensor modules 15 .

[0050] Then the electrically-controlled top drive wheel 5 is transferred to the top of the cable, and then the electrically-controlled lifting arm 4 will be controlled to descend, and then the lower end of the electrically-controlled top drive wheel 5 will be squeezed on the surface of the cable, thereby generating a reaction force on the gravity sensor module 15. When the gravity sensor module 15 detects the gravity value, the assembly status can be accurately known.

[0051] In order to cooperate with optical detection, the optical detection unit 8 includes an arc-shaped guide cover 81 fixed on the upper surface of the drone body 1, an electrically controlled adjustment frame 82 slidably installed inside the arc-shaped guide cover 81, an infrared temperature sensor 83 and a surface defect sensor 84 fixed inside the electrically controlled adjustment frame 82.

[0052] The electrically controlled adjustment frame 82 includes an adjustment motor fixed at the bottom of the arc-shaped guide cover 81 and a rotating cover with a notch slidably assembled inside the arc-shaped guide cover 81. The adjustment motor is driven by gears driven by pulleys on both sides. The adjustment motor drives the adjustment gears located on both sides of the arc-shaped guide cover 81 through the pulleys on both sides to control the rotating cover to rotate and adjust.

[0053] In order to monitor the assembly status, a self-weight sensor module 16 for obstacle avoidance is movably mounted on the outer side of the top assembly frame 44 .

[0054] When the electric-controlled lifting arms 4 on both sides flip over, the self-weight sensor module 16 will always maintain upward distance measurement due to the action of the bottom counterweight block. The distance measurement principle is the same as that of the optical rangefinder. When an obstacle is detected at the upper end, such as an adjacent cable, the drone body 1 will be controlled to move to the other side to avoid the cable and prevent the electric-controlled lifting arms 4 from hitting the adjacent cables.

[0055] When the value on the self-weight sensor module 16 increases to a constant value, and the values ​​of the self-weight sensor modules 16 on both sides are consistent, it means that the two electrically-controlled top drive wheels 5 are fully loaded on the cable. At this time, the electrically-controlled lifting arm 4 descends, the driving blades of the drone body 1 are closed, and the suspension mode is used for driving. Then, the optical detection unit 8 is transferred to the outside of the cable by lifting the drone body 1 upward, and then the electrically-controlled top drive wheel 5 rotates to drive the entire device to translate along the cable. At the same time, the optical detection unit 8 rotates synchronously to perform optical detection operations.

[0056] In order to ensure the consistency of the electric-controlled lifting arms 4 on both sides, an infrared positioning transceiver module 17 is installed on the side wall of the top assembly frame 44 .

[0057] The electric-controlled lifting arms 4 on both sides are flipped upward to the two sides of the cable. The infrared positioning transceiver modules 17 on the electric-controlled lifting arms 4 on both sides are infrared transmitting modules on one side and infrared receiving modules on the other side. When the electric-controlled lifting arms 4 on both sides are flipped upward to the specified position, the infrared transmitting module and the infrared receiving module will be started. If the infrared receiving module can receive the infrared signal, it means that the positions of the electric-controlled top driving wheels 5 on the inner top surfaces of the two are consistent, thereby ensuring that the electric-controlled top driving wheels 5 on the electric-controlled lifting arms 4 on both sides can be transferred to the upper surface of the cable; if no infrared signal is detected, it means that the positions of the electric-controlled top driving wheels 5 on both sides are inconsistent, and then the electric-controlled lifting arms 4 on both sides are flipped outward and flipped again for adjustment.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
