Description

Technical Field

[0001] This application relates to the field of power transmission line technology, and in particular to a robot inspection device for power transmission line insulators. Background Technology

[0002] The insulator inspection robot for power transmission lines is suitable for inspection operations of various high-voltage, ultra-high-voltage, and extra-high-voltage power transmission lines. It is especially suitable for areas with complex terrain, harsh environments, or where manual inspection is difficult, such as mountainous areas, lines crossing rivers, and high-altitude areas. It can efficiently and accurately locate and inspect insulator strings, promptly detect defects such as dirt, damage, and aging in insulators, ensure the safe and stable operation of power transmission lines, and reduce the labor intensity and safety risks of manual inspection.

[0003] Regarding the aforementioned technologies, the inventors believe that in the existing transmission line insulator inspection process, due to the lack of an effective positioning mechanism, the detection device often has difficulty accurately aligning with the insulator string for detection. This may not only lead to deviations in the detection results and affect the accurate judgment of the insulator string's condition, but may also reduce inspection efficiency and increase inspection time and cost due to multiple adjustments to the detection position. Utility Model Content

[0004] The purpose of this application is to provide a robot inspection device for insulator inspection of power transmission lines to improve the problem of lack of an effective positioning mechanism.

[0005] The technical solution of the transmission line insulator inspection robot detection device provided in this application is as follows:

[0006] A transmission line insulator inspection robot detection device includes a mounting frame. A positioning mechanism is located inside the mounting frame, and a detection mechanism is located on one side of the positioning mechanism. An inspection robot device is mounted on the lower surface of the mounting frame. A cable is slidably mounted inside the inspection robot device, and an insulator string is mounted at one end of the cable, located below the positioning mechanism and the detection mechanism. The positioning mechanism includes a positioning motor, one end of which is fixedly connected to one side of the mounting frame. A steering rod is fixedly mounted at the output end of the positioning motor, and both ends of the steering rod are rotatably connected to the inner walls of both sides of the mounting frame. A steering frame is fixedly mounted on the outer side of the steering rod, and two positioning rods are fixedly mounted on the lower surface of the steering frame. The lower ends of the positioning rods engage with the insulator string.

[0007] By adopting the above technical solution and using the positioning mechanism, the insulator string can be positioned, ensuring that the testing mechanism can accurately align with the insulator string for testing, thereby improving the accuracy and efficiency of the testing.

[0008] Optionally, the detection mechanism includes a fixed plate, which is fixedly connected to the bogie. An electric slide rail is fixedly mounted on one side of the fixed plate, and two electric sliders are slidably mounted on one side of the electric slide rail. A rotating frame is fixedly mounted on one side of the two electric sliders, and a rotating motor is fixedly mounted on one side of the rotating frame. A rotating rod is fixedly mounted at the output end of the rotating motor, and two adjusting rings are fixedly mounted on the outer side of the rotating rod. A detection needle is fixedly mounted on the outer side of the adjusting rings.

[0009] By adopting the above technical solution and through testing institutions, the degree of contamination and damage of insulators can be effectively detected.

[0010] Optionally, the lower surface of the mounting bracket has two mounting slots, which are fixedly engaged with the inspection robot equipment.

[0011] By adopting the above technical solution, the mounting slot allows the inspection robot to be securely fixed to the lower surface of the mounting frame, enhancing the stability and reliability of the entire device. At the same time, this fixing method also facilitates the installation and disassembly of the inspection robot, improving maintenance efficiency.

[0012] Optionally, an assembly frame is fixedly provided on one side of the mounting frame, and one side of the assembly frame is fixedly engaged with one end of the positioning motor.

[0013] By adopting the above technical solution, the mounting frame provides a stable mounting base for the positioning motor, allowing the positioning motor to be stably fixed to one side of the mounting frame. This not only ensures the normal operation of the positioning motor but also improves the stability and reliability of the entire positioning mechanism.

[0014] Optionally, the lower end of the positioning rod is fixedly provided with a positioning fork, which is engaged with the insulator string.

[0015] By adopting the above technical solution, the positioning fork enables the positioning rod to engage more accurately with the insulator string, improving the accuracy and stability of positioning. Furthermore, the shape and size of the positioning fork can be adjusted according to the specific conditions of the insulator string to accommodate different specifications and types of insulator strings.

[0016] Optionally, an adjusting bolt is inserted into the outer side of the adjusting ring, and the adjusting bolt is fixedly engaged with the outer side of the rotating rod.

[0017] By adopting the above technical solution, the adjusting bolt allows the adjusting ring to be flexibly adjusted on the rotating rod, thereby achieving precise control over the position of the detection pin. This adjustment method not only improves the accuracy of the detection but also enables the detection mechanism to adapt to the detection needs of insulator strings of different specifications and types.

[0018] Optionally, the outer side of the rotating rod is provided with a plurality of adjusting holes that are equally spaced, and the adjusting holes are fixedly engaged with adjusting bolts.

[0019] By adopting the above technical solution, the equal-spaced distribution of the adjustment holes on the rotating rod provides multiple fixed adjustment positions for the adjustment bolt, making the position adjustment of the adjustment ring and the detection needle more precise and convenient.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] This invention uses a positioning mechanism to position the insulator string, ensuring that the testing mechanism can accurately align with the insulator string for testing, thereby improving the accuracy and efficiency of the testing. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0027] Example

[0028] A transmission line insulator inspection robot testing device, referring to Figure 1 and Figure 2The system includes a mounting frame 1, a positioning mechanism 2 on the inner side of the mounting frame 1, a detection mechanism 3 on one side of the positioning mechanism 2, an inspection robot device 5 on the lower surface of the mounting frame 1, a cable 6 slidingly mounted on the inner side of the inspection robot device 5, and an insulator string 4 at one end of the cable 6. The insulator string 4 is located below the positioning mechanism 2 and the detection mechanism 3. The positioning mechanism 2 includes a positioning motor 20, one end of which is fixedly connected to one side of the mounting frame 1. A steering rod 22 is fixedly mounted on the output end of the positioning motor 20. The two ends of the steering rod 22 are rotatably connected to the inner walls of both sides of the mounting frame 1, respectively. A bogie 24 is fixedly mounted on the outer side of the steering rod 22. Two positioning rods 25 are fixedly mounted on the lower surface of the bogie 24. The lower ends of the positioning rods 25 engage with the insulator string 4. When the positioning mechanism 2 is in use, the positioning motor 20 is first started, and its output end drives the steering rod 22 to rotate between the inner walls of both sides of the mounting frame 1. As the steering rod 22 rotates, the bogie 24 fixed on its outer side also moves, thereby driving the two positioning rods 25 on the lower surface of the bogie 24 to move. The positioning fork 26 at the lower end of the positioning rod 25 gradually approaches and eventually engages with the insulator string 4, thereby achieving precise positioning of the insulator string 4 and providing accurate position information for subsequent testing.

[0029] Reference Figure 2 The lower surface of the mounting frame 1 has two mounting slots 21, which are fixedly engaged with the inspection robot device 5. The mounting slots 21 ensure that the inspection robot device 5 is securely fixed to the lower surface of the mounting frame 1, enhancing the stability and reliability of the entire device. At the same time, this fixing method facilitates the installation and disassembly of the inspection robot device 5, improving maintenance efficiency.

[0030] Reference Figure 2 An assembly frame 23 is fixedly mounted on one side of the mounting frame 1. One side of the assembly frame 23 is fixedly engaged with one end of the positioning motor 20. The assembly frame 23 provides a stable mounting base for the positioning motor 20, allowing the positioning motor 20 to be stably fixed on one side of the mounting frame 1. This not only ensures the normal operation of the positioning motor 20, but also improves the stability and reliability of the entire positioning mechanism 2.

[0031] Reference Figure 2 The lower end of the positioning rod 25 is fixedly equipped with a positioning fork 26, which engages with the insulator string 4. The positioning fork 26 enables the positioning rod 25 to engage more accurately with the insulator string 4, improving the accuracy and stability of positioning. At the same time, the shape and size of the positioning fork 26 can be adjusted according to the specific conditions of the insulator string 4 to accommodate insulator strings of different specifications and types.

[0032] Reference Figure 3The detection mechanism 3 includes a fixed plate 30, which is fixedly connected to the bogie 24. An electric slide rail 39 is fixedly mounted on one side of the fixed plate 30. Two electric sliders 31 are slidably mounted on one side of the electric slide rail 39. A rotating frame 37 is fixedly mounted on one side of the two electric sliders 31. A rotating motor 38 is fixedly mounted on one side of the rotating frame 37. A rotating rod 34 is fixedly mounted at the output end of the rotating motor 38. Two adjusting rings 35 are fixedly mounted on the outer side of the rotating rod 34. A detection needle 36 is fixedly mounted on the outer side of the adjusting rings 35. In use, the detection mechanism 3 first moves the rotating frame 37 to a suitable position by sliding the electric sliders 31 on the electric slide rail 39. Then, the rotating motor 38 starts, and its output end drives the rotating rod 34 to rotate. The adjusting rings 35 on the outer side of the rotating rod 34 move with the rotation of the rotating rod 34, thereby moving the detection needle 36 fixed on the outer side of the adjusting rings 35 to a position corresponding to the insulator string 4. The detection needle 36 then inspects the insulator string 4, obtaining relevant data about the insulator string 4 through contact, such as the degree of contamination and the extent of damage.

[0033] Reference Figure 3 An adjusting bolt 32 is inserted into the outer side of the adjusting ring 35. The adjusting bolt 32 is fixedly engaged with the outer side of the rotating rod 34. The adjusting bolt 32 allows the adjusting ring 35 to be flexibly adjusted on the rotating rod 34, thereby achieving precise control over the position of the detection needle 36. This adjustment method not only improves the accuracy of the detection but also enables the detection mechanism 3 to adapt to the detection needs of insulator strings 4 of different specifications and types.

[0034] Reference Figure 3 Multiple equal-spaced adjustment holes 33 are provided on the outer side of the rotating rod 34. The adjustment holes 33 are fixedly engaged with the adjustment bolts 32. The equal-spaced distribution of the adjustment holes 33 on the rotating rod 34 provides multiple fixed adjustment positions for the adjustment bolts 32, making the position adjustment of the adjustment ring 35 and the detection needle 36 more precise and convenient.

[0035] The implementation principle of this embodiment is as follows: When the positioning mechanism 2 is in use, it is first started by the positioning motor 20, whose output end drives the steering rod 22 to rotate between the inner walls on both sides of the mounting frame 1. As the steering rod 22 rotates, the bogie 24 fixed on its outer side also moves, thereby driving the two positioning rods 25 on the lower surface of the bogie 24 to move. The positioning fork 26 at the lower end of the positioning rod 25 gradually approaches and finally engages with the insulator string 4, thereby achieving precise positioning of the insulator string 4 and providing accurate position information for subsequent testing.

[0036] In operation, the testing mechanism 3 first moves the rotating frame 37 to a suitable position by sliding the electric slider 31 on the electric slide rail 39. Then, the rotating motor 38 starts, and its output drives the rotating rod 34 to rotate. The adjusting ring 35 on the outside of the rotating rod 34 moves with the rotation of the rotating rod 34, thereby moving the detection needle 36, which is fixed on the outside of the adjusting ring 35, to the position corresponding to the insulator string 4. The detection needle 36 then tests the insulator string 4, obtaining relevant data such as the degree of contamination and damage through contact.
