[0027] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0030] Existing cable inspection devices rely on camera technology to detect cables. When the cable surface is obstructed by dirt, it will cause false alarms or missed alarms, affecting the accuracy of detection.

[0031] like Figure 1-2 As shown, in order to overcome the above technical defects, this embodiment provides a high-altitude cable inspection device, including an inspection host 1, a camera mechanism 2, a walking mechanism 3 and a cleaning mechanism 4.

[0032] The inspection host 1 is equipped with a camera mechanism 2 for inspecting the cable 5; the inspection host 1 includes a chassis and equipment required for inspection installed in the chassis, such as batteries, control panels, etc. When other functional equipment needs to be carried, it can also be installed in the chassis; the principle of cable defect detection is image detection, so a camera mechanism 2 is set to capture images. In specific applications, software that can automatically analyze images can be pre-installed in the inspection host 1 to realize real-time field detection; the captured image information can also be sent to the ground processing end for analysis by wireless transmission.

[0033] The walking mechanism 3 is installed on the inspection host 1 and is used to drive the inspection host 1 to move along the cable 5; the walking mechanism 3 can be mounted on the cable 5, and it is powered and can move along the cable 5, driving the inspection host 1 and other mechanisms installed thereon to move forward synchronously, thereby achieving the purpose of mobile detection.

[0034] The cleaning mechanism 4 is installed on the inspection host 1, and includes a support rod 41 and a jet gun 42. The support rod 41 is installed on the inspection host 1, and the jet gun 42 is installed on the support rod 41. The cleaning mechanism 4 is provided with a jet gun 42, which can spray high-pressure air onto the surface of the cable 5 to remove dirt on the surface of the cable 5 without causing damage to the surface of the cable 5, and has the advantages of good cleaning effect and safety. The support rod 41 is used to support the jet gun 42 so that the jet gun 42 can be close to the cable 5 to ensure sufficient spray pressure. Preferably, the angle at which the jet gun 42 is installed on the support rod 41 is adjustable. After clamping, the staff can adjust the angle of the jet gun 42 so that the nozzle can face the cable 5. Among them, the forward direction of the inspection device is the positive direction, and the cleaning mechanism 4 needs to be set in front of the camera mechanism 2 to achieve cleaning first and then shooting.

[0035] In summary, the aerial cable inspection device of this embodiment is capable of autonomously traveling along the aerial cable 5. A camera mounted thereon automatically captures images of the cable surface, thus enabling automated inspection. Importantly, this solution incorporates a cleaning mechanism 4 mounted on the inspection host 1. This cleaning mechanism 4 includes an air jet 42 that automatically sprays high-pressure air onto the surface of the cable 5 before capturing images, removing dirt from the surface and preventing dirt covering the cable 5 from affecting the accuracy of image detection.

[0036] In one embodiment, a supercharger is installed in the inspection host 1 , and the air jet gun 42 is connected to the supercharger through an air pipe, and the supercharger provides high-pressure air to the air jet gun 42 .

[0037] The supercharger can compress the air and provide high-pressure air to the air gun 42 to achieve a continuous cleaning function. The supercharger can be provided in combination with existing technology.

[0038] In one embodiment, two groups of cleaning mechanisms 4 are symmetrically arranged on the inspection host 1, and the two groups of cleaning mechanisms 4 can spray and sweep the surface of the cable 5 from the left and right sides respectively.

[0039] Two sets of cleaning mechanisms 4 are symmetrically arranged on the left and right sides of the cable 5, respectively, to achieve comprehensive cleaning of the cable 5 surface and avoid cleaning blind spots. Since dirt generally adheres to the upper half of the cable 5 surface, the air jets 42 of the left and right cleaning mechanisms 4 are preferably arranged downwardly, so that the high-pressure center of the air jet can be aimed at the upper half of the cable 5 area.

[0040] In one embodiment, the support rod 41 is a lifting rod, and the air gun 42 is driven to descend by the support rod 41 so that the air gun 42 can avoid obstacles on the cable 5 .

[0041] Specifically, in order to install the cable 5, a bracket, wire clamp, and other devices are required to support and secure the cable. Since the air gun 42 is at least as high as the cable 5 when in operation, when the inspection device moves to the bracket and wire clamp, the cleaning mechanism 4 will interfere with or collide with the bracket or wire clamp, preventing the inspection device from moving forward. Therefore, the support rod 41 of this solution is configured as a lifting rod. When encountering an obstacle, it can automatically lower to avoid it, and then rise again after passing the obstacle to resume normal cleaning operations. The support rod 41 is equipped with a driving force and can be automatically raised and lowered by the control center.

[0042] Furthermore, the camera mechanism 2 includes a camera support rod 21 and a camera 22. The camera support rod 21 is mounted on the inspection host 1, and the camera 22 is mounted on the camera support rod 21. The camera support rod 21 is also a lifting rod, which can meet the obstacle avoidance requirements.

[0043] In one embodiment, the walking mechanism 3 includes an upper roller 31 and a lower roller 32 arranged one above the other. The upper roller 31 or the lower roller 32 is connected to a walking drive 33 .

[0044] Specifically, during operation, the cable 5 is clamped between the upper roller 31 and the lower roller 32. Driven by the travel drive 33, the upper roller 31 and the lower roller 32 can roll along the cable 5, thereby driving the inspection host 1 to move forward.

[0045] In one embodiment, the walking mechanism 3 is provided with at least three groups, and the walking mechanism 3 includes a roller bracket 34 installed on the inspection host 1, and the roller bracket 34 includes a translation drive group 341 and a lifting drive group 342 installed on the translation drive group 341. The translation drive group 341 can drive the lifting drive group 342 to move horizontally, and the upper roller 31 is installed on the lifting drive group 342. The lifting drive group 342 can drive the upper roller 31 to move up and down.

[0046] Based on this structure, the traveling mechanism 3 of this embodiment has an automatic obstacle avoidance function. Specifically, when encountering an obstacle, the corresponding roller bracket 34 drives the upper roller 31 to rise and then move horizontally away from the cable 5. The lifting drive group 342 then drives the upper roller 31 to a height below the obstacle. After the upper roller 31 passes the obstacle, the roller bracket 34 drives the upper roller 31 to return to its original position, cooperating with the lower roller 32 to clamp the cable 5.

[0047] Among them, since at least three groups of walking mechanisms 3 are provided, when crossing an obstacle, only one group of walking mechanisms 3 will detach from the cable 5 at a time, and the remaining walking mechanisms 3 will remain in a state of clamping the cable 5, so that the inspection device can be kept stably clamped under the cable 5.

[0048] In one embodiment, referring to Figure 3-4The translation drive group 341 includes a mounting seat 3411, a translation motor 3412, a screw 3414 and a nut. The mounting seat 3411 has a mounting slot. The screw 3414 is rotatably installed in the mounting slot. The translation motor 3412 is fixedly installed in the mounting slot. The translation motor 3412 is transmission-connected with the screw 3414, and the screw 3414 is driven to rotate by the translation motor 3412; the nut is threadedly installed on the screw 3414, and the lifting drive group 342 is fixedly connected with the nut, and the nut is driven to translate by the screw 3414, thereby driving the lifting drive group 342 to translate.

[0049] Specifically, the rotational freedom of the nut is restricted. When the screw 3414 rotates, the nut will move axially along the screw 3414, thereby driving the lifting drive group 342 and the upper roller 31 mounted thereon to move horizontally. The screw 3414 and nut cooperate in the transmission mode, which has the advantage of good stability.

[0050] In one embodiment, an L-shaped vertical partition 34111 is provided in the installation slot, and the L-shaped vertical partition 34111 divides the installation slot into a first installation slot and a second installation slot. The screw 3414 is installed through the first installation slot and the second installation slot, and the nut is set in the first installation slot. The part of the screw 3414 located in the second installation slot is connected to a driven gear 3415; the translation motor 3412 and the screw 3414 are installed side by side in the second installation slot, and the translation motor 3412 is connected to a driving gear 3413, and the driving gear 3413 is engaged with the driven gear 3415.

[0051] In this structure, an L-shaped vertical partition 34111 divides the mounting slot into a first and second mounting slot. The lift drive assembly 342 extends into the first mounting slot, where it slides and connects to a nut. The first mounting slot provides support and guidance for the translation of the lift drive assembly 342, while the second mounting slot securely secures the translation motor 3412. This structure offers the advantages of high reliability and ease of installation. Furthermore, the translation motor 3412 and screw 3414 can be installed side by side, reducing the left-right width of the entire translation drive assembly 341 and making the structure more compact.

[0052] In one embodiment, referring to Figure 3The lifting driving group 342 comprises a sleeve 3421, a rack 3422, a lifting motor 3423 and a lifting driving gear 3424, the lower end of the sleeve 3421 is connected to the translation driving group 341, and the upper end is provided with a mounting platform 34211; the rack 3422 is telescopically inserted into the sleeve 3421, and the lifting motor 3423 is mounted on the mounting platform 34211; the lifting driving gear 3424 is connected to the lifting motor 3423 and is engaged with the rack 3422, and the upper roller 31 is fixedly connected with the rack 3422.

[0053] The sleeve 3421 is arranged to mount the rack 3422, so as to provide reliable support and guidance for the rack 3422 and ensure that the rack 3422 can drive the upper roller 31 to stably lift. The lifting motor 3423 is provided with a self-locking mechanism, or is provided with a mechanism capable of locking the lifting driving gear 3424, when the upper roller 31 and the lower roller 32 cooperate to clamp the cable 5, the lifting driving gear 3424 is locked and fixed, and the rack 3422 cannot be elongated relative to the sleeve 3421; when the obstacle is crossed, after being unlocked, the lifting motor 3423 can drive the lifting driving gear 3424 to rotate, and then drive the rack 3422 to be telescopically extended.

[0054] In an embodiment, the walking mechanism 3 further comprises a lifting platform 35, the walking driving 33 is connected with the lower roller 32, and the lower roller 32 and the walking driving 33 are mounted on the lifting platform 35.

[0055] The lifting platform 35 is arranged to mount the lower roller 32 and the walking driving 33, and when an obstacle is encountered, the lifting platform 35 can drive the lower roller 32 and the walking driving 33 to descend to avoid the obstacle.
