[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a 10kV disconnector mechanical testing device includes a frame 1 and a slide assembly 2. The slide assembly 2 is fixedly connected to the frame 1. The test sample 8 is mounted on the frame 1 via the slide assembly 2. The frame 1 is provided with a height adjustment assembly 3, and the height adjustment assembly 3 is provided with a drive assembly 4. The drive assembly 4 is provided with a swing arm 43. The swing arm 43 is movably connected to a connecting shaft 5 connected to the test sample 8. The rotation center of the test sample 8 and the rotation center of the drive assembly 4 are aligned on the same axis through the height adjustment assembly 3. A photoelectric switch 6 is movably connected to the frame 1 in the vertical direction, intersecting with the swing arm 43 of the test sample 8. The frame 1 is equipped with a PLC controller 7 connected to the photoelectric switch 6. In this real-time example, the PLC controller 7 is equipped with a display screen, which can display the test results in real time. The PLC controller 7 is connected to the drive component 4, which can realize automated control of the drive component 4. In this embodiment, the frame 1 is equipped with a work platform 10. The slide assembly 2 and the height adjustment assembly 3 are both installed on the work platform 10. In this embodiment, there are several slide assemblies 2. The number of height adjustment assemblies 3 and photoelectric switches 6 corresponds to the number of slide assemblies 2. The height adjustment assemblies 3 and photoelectric switches 6 are respectively arranged on both sides of the slide assembly 2, which can simultaneously test multiple test samples 8.

[0023] The test sample 8 is fixed on the frame 1 by the slide assembly 2. Then, the height of the drive assembly 4 is adjusted by the height adjustment assembly 3 so that the rotation center pin 42 of the drive assembly 4 is on the same axis as the rotation center of the test sample 8. Then, the height of the photoelectric switch 6 is adjusted so that the photoelectric switch 6 and the swing arm 43 of the disconnect switch are in an intersecting state. The drive assembly 4 drives the swing arm 43 to swing repeatedly. Since the swing arm 43 is movably connected to the connecting shaft 5 connected to the test sample 8, the swing arm 43 can drive the test sample 8 to perform a swing test. During the test, the number of swings is collected in real time by the photoelectric switch 6, and the failure of the test sample 8 is monitored. The test results are transmitted to the PLC controller 7 in real time for easy reading by the test personnel, which greatly improves the test quality. Since the drive assembly 4 is connected to the PLC controller 7, the automatic control of the drive assembly 4 can be realized, thereby realizing automated testing, effectively reducing the workload of the operators and greatly improving the test efficiency.

[0024] The drive assembly 4 includes a servo motor 41 and a rotation center pin 42. The servo motor 41 is mounted on the height adjustment assembly 3. The swing arm 43 is mounted on the motor shaft of the servo motor 41. The rotation center pin 42 is located at the front end of the motor shaft of the servo motor 41. The swing arm 43 is provided with a horizontal sliding groove 44, and a sliding body 45 connected to the connecting shaft 5 is provided in the horizontal sliding groove 44. By configuring the drive assembly 4 with a servo motor 41 and a rotation center pin 42, and since the servo motor 41 is mounted on the height adjustment assembly 3, servo motor 41 can achieve servo-assisted rotation. The height adjustment of motor 41 and the alignment of the rotation center pin 42 with the rotation center of the test sample 8 and the drive component 4 ensure the precise positioning of the height adjustment component 3. By setting a sliding body 45 connected to the connecting shaft 5 in the horizontal sliding groove 44, the swing arm 43 can swing under the action of servo motor 41. Therefore, the connecting shaft 5 can slide in the horizontal sliding groove 44 under the action of sliding body 45. Servo motor 41 can ensure the stability of the test and effectively reduce the noise during the test, greatly improving the test effect.

[0025] The height adjustment assembly 3 includes a vertical plate 31, a vertical linear guide rail 32, and a sliding plate 33. The vertical plate 31 is fixedly connected to the frame 1. The vertical linear guide rail 32 is disposed on the vertical plate 31. The sliding plate 33 is provided with a slider 34 that cooperates with the vertical linear guide rail 32. The vertical plate 31 is provided with an adjustment mechanism 35 connected to the sliding plate 33. The servo motor 41 is fixedly connected to the sliding plate 33. The vertical plate 31 is provided with a vertical support for the servo motor 41 to slide. The slide groove 36, vertical linear guide rail 32, and slider 34 ensure the straightness of the slide plate 33 as it moves on the vertical plate 31. During operation, the slide plate 33 is adjusted by the adjustment mechanism 35, causing the slider 34 to move along the vertical linear guide rail 32. Since the servo motor 41 is fixed on the slide plate 33, the servo motor 41 can move synchronously with the slide plate 33, ensuring that the rotation center of the servo motor 41 and the rotation center of the test sample 8 are on the same axis. The vertical slide groove 36 ensures the sliding of the servo motor 41.

[0026] The adjustment mechanism 35 includes a fixing block 351 fixedly connected to the vertical plate 31, and a screw 352 disposed on the fixing block 351. The sliding plate 33 is provided with a threaded sleeve 341 connected to the screw 352. A knob 353 is provided at the bottom end of the screw 352. In use, the rotation of the screw 352 drives the threaded sleeve 341 to rise and fall. Since the threaded sleeve 341 is fixedly connected to the sliding plate 33, the sliding plate 33 can move synchronously with the threaded sleeve 341. The knob 353 facilitates operation. The operator operates the screw 352. Specifically, when the screw 352 rotates clockwise, the slider 34 moves upward on the vertical linear guide rail 32; when the screw 352 rotates counterclockwise, the slider 34 moves downward on the vertical linear guide rail 32. The fixing block 351 can realize the installation and fixation of the screw 352. In this embodiment, the fixing block 351 and the vertical plate 31 are an integral structure, which simplifies the installation process of the fixing block 351 and the vertical plate 31 and improves the connection strength between the fixing block 351 and the vertical plate 31. The sliding body 45 includes a roller 451 and a connecting sleeve 452 disposed in the roller 451. The roller 451 is disposed in the horizontal sliding groove 44. The connecting shaft 5 is threadedly installed in the connecting sleeve 452. The roller 451 can ensure the stability of the sliding body 45, and the connecting sleeve 452 facilitates the connection and fixation with the connecting shaft 5, making installation and disassembly convenient. The vertical plate 31 is provided with a limiting rod 37, and the slide plate 33 is provided with a limiting groove 38. The limiting rod 37 is set in the limiting groove 38, which can effectively limit the movement and displacement of the slide plate 33. In this embodiment, the slide plate 33 is provided with a vertical plate, and the limiting groove 38 is set on the vertical plate.

[0027] The slide assembly 2 includes a fixed plate 21, a right horizontal plate 22, and a left horizontal plate 23. The right horizontal plate 22 is fixedly connected to the fixed plate 21, and the left horizontal plate 23 is slidably connected to the fixed plate 21. An installation groove 24 for mounting the test sample 8 is formed between the left horizontal plate 23 and the right horizontal plate 22. A pressure plate 25 is provided between the right horizontal plate 22 and the left horizontal plate 23 to abut against the test sample 8. The pressure plate 25 is detachably installed between the right horizontal plate 22 and the left horizontal plate 23, which can realize the quick installation and fixing of the test sample 8. Moreover, since the left horizontal plate 23 is slidably connected to the fixed plate 21, the size of the installation groove 24 can be adjusted according to different models of test samples 8 to meet different testing requirements. The setting of the pressure plate 25 can press the test sample 8 into the installation groove 24 to ensure that the test sample 8 is installed firmly and reliably.

[0028] The fixing plate 21 is provided with screws 26, and the left horizontal plate 23 is provided with a strip hole 27. The screws 26 are set in the strip hole 27. During installation, the screws 26 are loosened so that the left horizontal plate 23 is not restricted by the screws 26, and the test sample 8 is placed in the mounting groove 24. Then, the position of the left horizontal plate 23 is adjusted by sliding the strip hole 27 on the screws 26. When the left horizontal plate 23 abuts against the test sample 8, the screws 26 are tightened to lock the left horizontal plate 23 onto the fixing plate 21. The entire installation structure is simple, and the strip hole 27 can ensure the straightness of the left horizontal plate 23 when it moves, and ensure the contact quality between the left horizontal plate 23 and the test sample 8. Both ends of the pressure plate 25 are detachably installed between the right horizontal plate 22 and the left horizontal plate 23 by bolts 28, which simplifies the installation structure of the pressure plate 25. The bolts 28 are easy to install and remove and the connection is reliable. In this embodiment, both ends of the pressure plate 25 are provided with downward extending sections. When the pressure plate 25 is installed, the extending sections abut against the left horizontal plate 23 and the right horizontal plate 22 respectively, which can improve the pressing quality of the pressure plate 25.

[0029] The frame 1 is provided with a vertical light rod 11. In this embodiment, the bottom end of the vertical light rod 11 is provided with a connecting seat connected to the working platform 10, which can increase the contact area between the entire vertical light rod 11 and the frame 1 and improve the fixing quality of the vertical light rod 11. The vertical light rod 11 is provided with a sliding seat 12, which can realize the height adjustment of the photoelectric switch 6 on the vertical light rod 11 to meet different testing requirements. The sliding seat 12 is provided with a locking screw 2613 to lock the sliding seat 12 onto the vertical light rod 11. The locking screw 2613 is provided to lock the sliding seat 12. Securely fastened to the vertical light rod 11, in specific operation, when the sliding seat 12 needs to be raised or lowered, simply loosen the locking screw 2613, and after the sliding seat 12 slides, tighten the locking screw 2613 to lock the sliding seat 12, thus preventing the sliding seat 12 from moving relative to the vertical light rod 11 during the test. The sliding seat 12 is provided with a mounting plate 14 for mounting the photoelectric switch 6. In this embodiment, the mounting plate 14 includes a horizontal part and a vertical part. The horizontal part is located at the top of the vertical part, the vertical part is located on the sliding seat 12, and the photoelectric switch 6 is located on the horizontal part.
