[0001] This invention relates to the field of cable testing technology, and in particular to an outdoor high-altitude cable testing device equipped with a Tiantong data transmission network. Background Technology

[0002] With the development of power technology, the need for long-distance power transmission and distribution has led to the use of outdoor high-altitude cables. These cables, suspended high in the air, transmit electrical energy to various areas and then distribute it to residential, commercial, and industrial users. They are commonly used in urban and industrial areas because they effectively reduce land use, decrease environmental pollution, and improve the reliability and security of power systems.

[0003] To improve the operational stability of outdoor cables, regular inspection and maintenance of the cable surface are necessary. However, current high-altitude cables, especially those located in mountainous and forested areas, face limited installation locations, resulting in high costs and difficulties for manual maintenance, limited safety, and long maintenance cycles. These factors all affect the timeliness of inspection and maintenance.

[0004] Therefore, there is a need to provide an outdoor high-altitude cable detection device with a data transmission network to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an outdoor high-altitude cable detection device with a Tiantong data transmission network, which is highly safe, has good maintenance efficiency, and is low in cost.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0011] Preferably, a first transmission gear is axially fitted on the upper outer side of the internal thread adjusting cylinder, and a second transmission gear that cooperates with the first transmission gear is axially assembled on both sides of the control motor.

[0012] Preferably, the side wall of the external threaded lifting tube is provided with a strip-shaped limiting port, and the inner side of the flipping adjusting cylinder has an internal limiting block that protrudes into the strip-shaped limiting port.

[0013] Preferably, the top mounting frame has lateral mounting seats on both sides for mounting the electrically controlled top drive wheel, and a gravity sensing module is provided inside the lateral mounting seat at the mounting end of the electrically controlled top drive wheel.

[0037] Figure 1 , Figure 2 , Figure 3 and Figure 4 The outdoor high-altitude cable detection device with Tiantong data transmission network shown includes a UAV body 1 with an airborne Tiantong satellite communication system. Lateral flipping assembly slots 2 are opened on both sides of the UAV body 1. An electrically controlled flipping adjustment mechanism 3 is movably installed inside the lateral flipping assembly slot 2. An electrically controlled lifting arm 4 is movably installed inside the electrically controlled flipping adjustment mechanism 3. An electrically controlled top drive wheel 5 is movably installed on the inner top surface of the electrically controlled lifting arm 4. A visual sensing probe 6, an optical ranging probe 7, and an optical detection unit 8 are installed on the upper surface of the UAV body 1.

[0038] Working Principle: The drone body 1 is remotely controlled to take off and land, then moves the detection equipment directly beneath one end of the cable. The visual sensor 6 visually observes the position of all cables, while the optical ranging probe 7 uses laser monitoring to accurately calculate the position and distance of the cable directly above. This precise positioning, coordinated with the drone body 1, allows it to hover directly beneath the cable to be inspected. Once the positioning is confirmed, the electrically controlled tilting adjustment mechanisms 3 on both sides are activated, tilting upwards and moving the electrically controlled top drive wheel 5 on the inner top surface of the electrically controlled lifting arm 4 directly above the cable. The electrically controlled lifting arm 4 then descends, controlling the electrically controlled top drive wheel 5 to descend to the upper surface of the cable. The drone body 1 is then deactivated, and the optical ranging probe 7 performs distance detection. When the cable reaches the center position of the optical detection unit 8, the electrically controlled lifting arm 4 stops descending, and the electrically controlled top drive wheel 5 moves the entire device horizontally. Simultaneously, the optical detection unit 8 begins to rotate, performing a surround detection of the cable's perimeter. Then, the airborne Tiantong satellite communication system transmits detection signals via satellite, thus enabling the transmission of text signals by receiving satellite communication signals even in the absence of base station signals. The principle is the same as that of mobile phone satellite communication.

[0039] To facilitate bottom support and positioning, the upper surface of the drone body 1 is movably fitted with a bottom guide and positioning wheel 9 that cooperates with the electronically controlled top drive wheel 5.

[0040] When the electrically controlled lifting arm 4 descends to its lowest position, the lower end of the electrically controlled top drive wheel 5 is supported by the upper end of the cable, while the upper end of the bottom guide limit wheel 9 is supported by the lower end of the cable, thus improving stability and guidance during the translation process.

[0041] Both the electrically controlled top drive wheel 5 and the bottom guide limit wheel 9 have arc-shaped limit grooves on their outer arc surfaces, which can improve their fit with the cable surface and their lateral limit performance.

[0042] To facilitate the tilting adjustment, the electrically controlled tilting adjustment mechanism 3 includes a tilting adjustment cylinder 31 that is movably mounted in the lateral tilting assembly slot 2 via two side shafts, and a side-mounted electrically controlled support rod 32 for controlling the tilting adjustment cylinder 31.

[0043] The side-mounted electric control support rod 32 controls the tilting adjustment cylinder 31 to tilt and adjust inside the side tilting assembly slot 2 by telescoping.

[0044] To facilitate lifting and adjustment, the electrically controlled lifting arm 4 includes a control motor 41 installed inside the UAV body 1, an internally threaded adjusting cylinder 42 movably installed inside the tilting adjusting cylinder 31, an externally threaded lifting tube 43 threaded into the internally threaded adjusting cylinder 42, and an n-shaped top mounting frame 44 axially fixed to the top of the externally threaded lifting tube 43.

[0045] To facilitate meshing and driving, a first transmission gear 10 is axially mounted on the upper outer side of the internal thread adjusting cylinder 42, and a second transmission gear 11 that meshes with the first transmission gear 10 is axially mounted on both sides of the control motor 41.

[0046] When the side-mounted electric control support rod 32 retracts to control the upper end of the tilting adjustment cylinder 31 to tilt inward, the first transmission gear 10 at the upper outer side of the inner thread adjustment cylinder 42 will eventually mesh with the second transmission gear 11. Then, the control motor 41 drives the second transmission gear 11 to rotate, thereby controlling the rotation of the inner thread adjustment cylinder 42. The rotation of the inner thread adjustment cylinder 42 can drive the outer thread lifting tube 43 to move up and down along the inner thread adjustment cylinder 42.

[0047] To facilitate lateral positioning and improve guidance, a strip-shaped limiting port 12 is provided on the side wall of the external threaded lifting pipe 43, and an internal limiting block 13 protruding into the strip-shaped limiting port 12 is provided on the inner side of the flip-adjusting cylinder 31.

[0048] To facilitate lateral assembly and gravity monitoring, the top assembly frame 44 has lateral assembly seats 14 on both sides for mounting the electrically controlled top drive wheel 5. A gravity sensing module 15 is provided inside the lateral assembly seat 14 at the assembly end of the electrically controlled top drive wheel 5.

[0049] The mounting shafts on both sides of the electrically controlled top drive wheel 5 are inserted into the lateral mounting base 14 and contact the gravity sensing module 15.

[0050] Then the electrically controlled top drive wheel 5 moves above the cable, and the electrically controlled lifting arm 4 will control the descent. Then the lower end of the electrically controlled top drive wheel 5 will press against the surface of the cable, thereby generating a reaction force on the gravity sensing module 15. When the gravity sensing module 15 detects the gravity value, it can accurately know the assembly status.

[0051] To facilitate optical inspection, the optical inspection unit 8 includes an arc-shaped guide cover 81 fixed to the upper surface of the UAV body 1, an electrically controlled adjustment frame 82 slidably installed inside the arc-shaped guide cover 81, an infrared temperature sensor 83 fixed inside the electrically controlled adjustment frame 82, and a surface defect sensor 84.

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

[0053] 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 two electrically controlled lifting arms 4 flip, the self-weight sensor module 16 will always keep measuring the distance upward due to the effect of the bottom counterweight. The principle of distance measurement is the same as that of an optical rangefinder. When an obstacle is detected at the top, 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 electrically controlled lifting arms 4 from hitting the adjacent cable.

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

[0056] To ensure consistency between the two electrically controlled lifting arms 4, an infrared positioning transceiver module 17 is installed on the side wall of the top mounting frame 44.

[0057] The electrically controlled lifting arms 4 on both sides flip upwards to the sides of the cable. The infrared positioning transceiver module 17 on the electrically controlled lifting arms 4 on both sides is an infrared emitting module on one side and an infrared receiving module on the other side. When the electrically controlled lifting arms 4 on both sides flip upwards to the designated position, the infrared emitting module and the infrared receiving module will be activated. If the infrared receiving module can receive the infrared signal, it means that the electrically controlled top drive wheel 5 on the inner top surface of both sides is in the same position, thus ensuring that the electrically controlled top drive wheel 5 on the electrically 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 electrically controlled top drive wheel 5 on both sides is not in the same position. Then the electrically controlled lifting arms 4 on both sides flip outwards and readjust.

[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 implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
