[0016] Compared with the prior art, the present invention provides a power inspection robot that is easy to assemble and disassemble, and has the following beneficial effects:

[0017] 1. This invention enables stable movement during power inspection by setting up a moving mechanism, thereby eliminating the need for manual inspection and greatly saving manpower. The moving device moves forward by swinging back and forth, which makes the mechanism move relatively slowly, but allows for more detailed inspection of the outer wall of the cable.

[0018] 2. This invention sets up a detection mechanism for detecting the outer wall of the cable. By dividing the outer wall of the cable into four areas, it can conduct more detailed detection of the outer wall of the cable during power inspection. When the cable has a problem, this detection method will produce a more obvious reaction, thereby ensuring that the staff can more accurately locate the problem when dealing with the problem.

[0019] 3. By setting up a marking mechanism, the present invention can mark the problematic parts of the cable. In this way, when the staff inspects the cable, they only need to see the marking to determine that the cable is abnormal, without having to spend a lot of manpower to conduct a detailed inspection, thus effectively saving labor costs.

[0020] 4. By setting a third sliding plate, when the detection mechanism detects a problem with the outer wall of the cable, the information can be effectively transmitted to the marking mechanism through the third sliding plate. In this way, when the outer wall of the cable is damaged, the marking mechanism can mark it at a position away from the damaged area, thereby avoiding secondary damage to the damaged area of ​​the cable outer wall.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] Example 1: See Figures 1-4The present invention provides a technical solution: a power inspection robot that is easy to assemble and disassemble, comprising a protective shell 1, two sets of rebound rods 2 provided on the inner wall of the protective shell 1, the side of the two sets of rebound rods 2 near the protective shell 1 being fixedly connected to the inner wall of the protective shell 1, and a bonding plate 3 fixedly connected to the side of the two sets of rebound rods 2 away from the protective shell 1, and two sets of first sliding plates 4 slidably connected to the inner wall of the two sets of bonding plates 3, and further comprising:

[0034] The moving mechanism 5 includes a fixed block 501, which is fixedly connected to the top of the protective shell 1 on the side closest to it. Connecting rods 502 are fixedly connected to both sides of the fixed block 501. A first spring 507 is provided on the side of each connecting rod 502 away from the fixed block 501, and the side of each first spring 507 near the connecting rod 502 contacts the outer wall of the connecting rod 502. Two sets of contact plates 503 are provided on the outer wall of the protective shell 1, and the side of each contact plate 503 near the protective shell 1 is fixedly connected to the outer wall of the protective shell 1. A swing plate 504 is rotatably connected to the side of each contact plate 503 away from the protective shell 1 via a first rotating shaft. A pull rope 505 is provided on the side of each swing plate 504 away from the protective shell 1. By setting a rocking ball 506, the swing plate 504 can be rotated multiple times, thus ensuring that the protective shell 1 can be moved by the rocking force. The cable moves slowly. The two sets of pull ropes 505 are fixedly connected to the inner wall of the swing plate 504 on the side near the swing plate 504. The first spring 507 is used to push and push to move back to the starting position. The two sets of pull ropes 505 are fixedly connected to the rocking ball 506 on the side away from the swing plate 504. The top of the two sets of swing plates 504 is fixedly connected to the push plate 508. The two sets of push plates 508 are slidably connected to the outer wall of the connecting rod 502 on the side near the connecting rod 502. The two sets of push plates 508 are fixedly connected to the first spring 507 on the side near the first spring 507. By setting the first spring 507, the rebound force of the first spring 507 can ensure that the swing plate 504 can reciprocate. In this way, the swing plate 504 can perform multiple rocking actions, thereby driving the protective shell 1 to move a certain distance. The rocking ball 506 is used to drive the swing plate 504 to rotate.

[0035] The working principle of this embodiment is as follows: When the operator begins cable inspection, they first hold the protective shell 1 and slowly move it along the outer wall of the cable. During this process, the cable gradually passes through the bottom of the protective shell 1 and contacts the bonding plate 3. Due to differences in cable specifications, the bonding plate 3 will automatically adapt to the actual size of the cable. When the bonding plate 3 moves, it will generate a pushing force on the return rod 2, causing the return rod 2 to retract, thereby ensuring that the cable can smoothly enter the interior of the bonding plate 3. When a power inspection operation is required, the operator rotates one end of the swing plate 504, causing it to rotate away from the protective shell 1. At this time, the push plate 508 located at the top of the swing plate 504 will slide smoothly along the connecting rod 502 under the drive of the swing plate 504. When the push plate 508 slides, it will apply a pushing force to the first spring 507, causing the first spring 507 to retract. When the push plate 508 is no longer pushed by an external force, the first spring 507 begins to rebound due to its own elastic restoring force, giving the push plate 508 a reverse thrust, causing the push plate 508 to perform a reset movement. As the push plate 508 drives the swing plate 504 to rotate, the pull rope 505 at the bottom of the swing plate 504 will shake accordingly. The shaking of the pull rope 505 will cause the rocking ball 506 to start to swing. The rocking ball 506 will move to the side away from the swing plate 504. This movement process, in turn, will cause the swing plate 504 to rotate again, thereby driving the push plate 508 to continuously apply a thrust to the first spring 507. This process repeats, and the shaking effect produced by this series of actions can drive the protective shell 1 to move slowly a distance on the horizontal cable. After the protective shell 1 stops moving, the staff can begin a comprehensive and detailed inspection of the outer wall of the cable.

[0036] Example 2: Please refer to Figures 5-7Based on Embodiment 1, the present invention provides a technical solution that further includes a detection mechanism 6. The detection mechanism 6 includes a first connecting block 601. The side of the first connecting block 601 closest to the first sliding plate 4 is fixedly connected to the front of the first sliding plate 4. A first positioning rod 602 is slidably connected to the inner wall of the first connecting block 601. A connecting ring 605 is fixedly connected to the side of the first positioning rod 602 away from the first connecting block 601. The first positioning rod 602 is used to push the connecting ring 605 to move. An arc-shaped block 603 is fixedly connected to the side of the connecting ring 605 away from the first positioning rod 602. Two sets of curved blocks 607 are provided on the outer wall of the arc-shaped block 603. A second sliding plate 608 is slidably connected to the inner wall of each set of curved blocks 607. The arc-shaped block 603 is used to fix the position of the curved blocks 607. The two sets of second sliding plates 608 are close to the curved blocks 607. A second spring 610 is fixedly connected to one side of the 7. The inner wall of the second spring 610 contacts the inner wall of the curved block 607. An elastic band 609 is fixedly connected to the side of the two sets of second sliding plates 608 near the connecting ring 605. The elastic band 609 is used to limit the movement distance of the first positioning rod 602. By setting the elastic band 609, the measuring rod 606 can be fixed, so that the measuring rod 606 will not move arbitrarily, and the problem of inaccurate measurement of the outer wall of the cable can be prevented. The side of the two sets of elastic bands 609 away from the second sliding plate 608 contacts the outer wall of the first positioning rod 602. A moving plate 604 is fixedly connected to the side of the two sets of first positioning rods 602 near the arc block 603. The detection mechanism 6 is set into four sets, all installed around the inner wall of the protective shell 1. The moving plate 604 is used to detect whether there is damage on the outer surface of the cable.

[0037] The working principle of this embodiment is as follows: When the cable is embedded inside the bonding plate 3, the operator begins to move the first positioning rod 602, causing it to slide along the first connecting block 601. The movement of the first positioning rod 602 drives the connecting ring 605 to move synchronously. The movement of the connecting ring 605 pushes the arc-shaped block 603 towards the outer wall of the cable. The movement of the arc-shaped block 603 further drives the bending block 607 to move. The bending block 607 then drives the measuring rod 606 to move. The movement of the measuring rod 606 pulls the elastic band 609. At the same time, the movement of the bending block 607 also drives the second sliding block to move. The movement of the measuring rod 606 pushes the moving plate 604 towards the cable. When the outer wall is in contact with the cable, the second spring 610 is in a contracted state, ensuring that the elastic band 609 does not restrict the normal movement of the measuring rod 606. After the moving plate 604 is fully in contact with the outer wall of the cable, the operator releases the elastic band 609, and the second spring 610 loses its thrust and begins to rebound. During the rebound process, the second spring 610 drives the second sliding plate 608 to slide along the bent block 607, so that the elastic band 609 restricts the autonomous movement of the measuring rod 606. The movement of the protective shell 1 drives the detection mechanism 6 to move synchronously. If there are protrusions or depressions on the outer wall of the cable, the moving plate 604 will shake, thereby achieving effective detection of the outer wall of the cable.

[0038] Example 3: Please refer to Figure 8 Based on Embodiments 1 and 2, the present invention provides a technical solution that further includes a marking mechanism 7. The marking mechanism 7 includes a second connecting block 701, the side of the second connecting block 701 closest to the first sliding plate 4 being fixedly connected to the first sliding plate 4. A second positioning rod 702 is slidably connected to the inner wall of the second connecting block 701. A third sliding plate 703 is provided on the outer wall of the second positioning rod 702, the side of the third sliding plate 703 closest to the second positioning rod 702 being slidably connected to the outer wall of the second positioning rod 702. The second positioning rod 702 is used to fix the sliding angle of the third sliding plate 703. By setting the third sliding plate 703, it can be ensured that when the detection mechanism 6 moves, the marking mechanism 7 will also move, thereby ensuring the accuracy of the marking. The side of the third sliding plate 703 closest to the measuring rod 606 is fixedly connected to the top of the measuring rod 606, and the side of the third sliding plate 703 furthest from the second connecting block 701 is fixedly connected to... The third spring 704 is fixedly connected to a limiting plate 705 on the side away from the third sliding plate 703. The limiting plate 705 is slidably connected to the outer wall of the second positioning rod 702 on the side near the second positioning rod 702. With the help of the third spring 704, the limiting plate 705 can be moved up and down during the stretching or contraction process. In this way, once a problem occurs on the outer wall of the cable, the problem location can be accurately marked by the up and down movement of the limiting plate 705, thereby reducing the workload of manual inspection. The third spring 704 is used to pull the limiting plate 705 to move up and down. A marking pen 706 is fixedly connected to the side of the limiting plate 705 away from the third sliding plate 703. The marking pen 706 is slidably connected to the third sliding plate 703 on the side near the third sliding plate 703. The marking mechanism 7 is set into four groups, all installed around the inner wall of the protective shell 1. The marking pen 706 is used to mark the outer surface of the cable.

[0039] The working principle of this embodiment is as follows: When the moving plate 604 shakes, it will drive the measuring rod 606 to move accordingly. During the movement of the measuring rod 606, two different situations will occur: First, when the measuring rod 606 moves downwards, it will no longer support the third sliding plate 703; second, when the measuring rod 606 moves upwards, it will push the third sliding plate 703 to move upwards synchronously. The third sliding plate 703 will slide on the second positioning rod 702. When the third sliding plate 703 slides downwards, it will cause the third spring 704 to begin to contract, and at this time, the other side of the third spring 704 will... The limiting plate 705 is pushed to slide on the second positioning rod 702. During the sliding process of the limiting plate 705, the marking pen 706 will leave a deep mark on the outer wall of the cable. When the third sliding plate 703 moves upward, it will pull the third spring 704 to extend it. Then the third spring 704 pulls the limiting plate 705 upward. The limiting plate 705 drives the marking pen 706 to move upward synchronously. Due to this sudden upward movement of the marking pen 706, the marking characteristics left on the outer wall of the cable are different from the markings left when moving horizontally. Based on this, it can be determined that there is a problem with the outer wall of the cable, and then the relevant work can be completed.

[0040] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
