Description

Technical Field

[0001] This utility model relates to the field of power technology, specifically to a GIS terminal stress cone testing device. Background Technology

[0002] GIS terminal, short for Gas Insulated Terminal, is a key cable accessory in power systems. It is a cable terminal installed inside gas-insulated enclosed switchgear, with sulfur hexafluoride gas as the external insulation. It is an essential product for SF6 switchgear to realize cable entry, and is also commonly used for connecting cables and transformers. It can realize the safe transmission and connection of power and ensure the stable operation of high-voltage power systems.

[0003] The stress cone in a GIS terminal is a core component for electric field control within the GIS terminal. Currently, the stress cone needs to be tested before use. After undergoing simulated environmental tests such as thermal aging and damp heat aging, its hardness change needs to be tested using specialized equipment such as a Shore hardness tester to determine whether the rubber material has become brittle or softened. However, the silicone rubber material of the stress cone is sticky, and after testing, fine rubber debris easily adheres to the indenter of the hardness tester. During traditional cleaning, the debris often falls off the indenter and scatters on the surface of the test bench, contaminating the test environment and hindering the use of the device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a new technical solution:

[0026] Base plate 1: Serves as the supporting foundation for the entire testing device. It is placed horizontally on the workbench and used to fix the mounting bracket 2 and the testing table 4 to ensure the overall stability of the device.

[0027] Support 2: Vertically fixedly installed on the upper surface of the base plate 1, providing installation support for the Shore hardness tester body 3, and also serving as a sliding track for the connecting plate 11, allowing for height adjustment in conjunction with the hardness tester;

[0028] Shore hardness tester body 3: mounted on the upper end of bracket 2, it is the core equipment for stress cone hardness testing. The indenter at its lower end is used to directly contact the stress cone sample to detect and provide feedback on hardness data.

[0029] Test platform 4: Fixedly installed on the upper surface of base plate 1, used to place stress cone samples, and the pressure pin can accurately contact the test surface;

[0030] Annular plate 5: Rotatably mounted on the lower end of the outer surface of bracket 2, and connected to connecting plate 11 via rotating connecting plate 13. Its core function is to drive connecting rod 7, collection box 8 and rotating plate 6 to rotate synchronously, thereby switching between cleaning position and avoidance position.

[0031] Rotating plate 6: Rotatably installed inside the upper part of the collection box 8, it has two forms and is used to install the round rod 9 and drive it to rotate, providing power transmission for needle cleaning;

[0032] Connecting rod 7: The front end is connected to the collection box 8 and the rear end is fixed to the annular plate 5. It is the intermediate component connecting the annular plate 5 and the collection box 8. It is used to transmit the rotation and lifting power of the annular plate 5 and drive the collection box 8 to move synchronously.

[0033] Collection box 8: The upper end is open and it is installed at the front end of the connecting rod 7 by connecting screw 18. Its main function is to collect the rubber debris that falls during cleaning and prevent the debris from scattering to the test table 4 or around the device.

[0034] Round rod 9: It is fixedly connected to the inner wall of the rotating plate 6, and a cleaning cloth 10 is sleeved on its outer surface. When the rotating plate 6 rotates, it drives the cleaning cloth 10 to move synchronously, so that the cleaning cloth 10 can fully contact the lower end of the pressure needle.

[0035] Cleaning cloth 10: It is covered on the outer surface of the round rod 9. It is made of soft material and has absorbency. It rubs against the lower end of the pressure needle under the action of the round rod 9 to wipe and clean the rubber debris attached to the pressure needle.

[0036] Connecting plate 11: It is slidably installed on the outer surface of the bracket 2. Its upper end is fixedly connected to the main body 3 of the Shore hardness tester, and its lower end is rotatably connected to the annular plate 5. Its core function is to realize the synchronous linkage between the auxiliary mechanism and the hardness tester. When the hardness tester adjusts its height, it drives the annular plate 5, the collection box 8 and other components to rise and fall synchronously.

[0037] Rotary connecting groove 12: It is formed on the lower surface of the connecting plate 11 to provide rotational installation space for the rotating connecting plate 13, limit the range of motion of the rotating connecting plate 13, and ensure that it can only rotate around a fixed axis;

[0038] Rotary connecting plate 13: Rotaryly installed inside the rotary connecting groove 12, one end is fixedly connected to the annular plate 5, and the other end is movably connected to the connecting plate 11. It is a rotation transmission component between the connecting plate 11 and the annular plate 5, enabling the annular plate 5 to rotate relative to the connecting plate 11.

[0039] Arc-shaped limiting groove 14: It is formed on the inner wall of the rotating connecting groove 12 and has an arc-shaped structure. It is used to limit the sliding range of the limiting rod 15, thereby controlling the rotation angle of the annular plate 5 and ensuring that the collection box 8 can be accurately stopped below the pressure needle or at the left avoidance position.

[0040] Limiting rod 15: It is fixedly connected to the rotating connecting plate 13 and slidably installed inside the arc-shaped limiting groove 14. It cooperates with the arc-shaped limiting groove 14 to prevent the annular plate 5 from rotating excessively and to ensure the accuracy of the cleaning position.

[0041] Handles 16: are fixedly connected to the outer surface of the rotating plate 6 in a ring array, making it easy for operators to manually hold and rotate the rotating plate 6, providing a convenient force application point for the rotation of the rotating plate 6;

[0042] Threaded groove 17: It is formed on the front surface of the connecting rod 7 and cooperates with the connecting screw 18 to form a threaded connection structure, providing a detachable installation method for the collection box 8, which facilitates subsequent disassembly and cleaning of the collection box 8;

[0043] Connecting screw 18: One end is fixedly connected to the collection box 8, and the other end is threaded into the inside of the threaded groove 17. It is a detachable connecting part between the collection box 8 and the connecting rod 7, enabling quick assembly and disassembly of the collection box 8.

[0044] Limiting screw 19: Used only when the rotating plate 6 is a convex ring plate with an annular groove on the outer surface. It is threaded onto the outer surface of the collection box 8, with the adjacent end penetrating into the annular groove. It is used to further limit the rotating plate 6 and prevent the rotating plate 6 from shifting under vibration.

[0045] Furthermore, when using this device, the stress cone sample after aging treatment is fixed on the test bench 4. The height of the Shore hardness tester body 3 is adjusted by the bracket 2. The connecting plate 11 slides synchronously along the bracket 2 with the hardness tester. The annular plate 5 is linked with the connecting plate 11 by rotating the connecting plate 13, which drives the collection box 8 and the rotating plate 6 to rise and fall synchronously, ensuring that the hardness tester indenter is aligned with the sample test position. The hardness test of the stress cone sample is completed using the Shore hardness tester body 3 according to the standard procedure. During the test, the collection box 8 and the rotating plate 6 are in the left position, which does not affect the contact between the indenter and the sample. After the test, the annular plate 5 is rotated, and the collection box 8 and the rotating plate 6 are positioned directly below the indenter through the cooperation of the arc-shaped limiting groove 14 and the limiting rod 15. Hold handle 16 and rotate the rotating plate 6. The round rod 9 on the inner wall of the rotating plate 6 and the sleeved cleaning cloth 10 rotate synchronously with the rotating plate. The cleaning cloth 10 makes full contact and friction with the lower end of the pressure needle to clean the attached rubber debris. Some of the debris generated during cleaning adheres to the surface of the cleaning cloth 10, and the other part falls into the collection box 8 with the upper opening. Rotate the annular plate 5 in the opposite direction to turn the collection box 8 and the rotating plate 6 back to the left position, avoiding the pressure needle, and then you can carry out the next stress cone sample hardness test. When it is necessary to clean the cleaning cloth 10, simply remove the rotating plate 6 with the convex annular plate structure from the upper end of the collection box 8. When it is necessary to clean the collection box 8, rotate the collection box 8 to disengage the connecting screw 18 from the thread groove 17 of the connecting rod 7, and remove the collection box 8 to complete the cleaning.

[0046] By setting up the annular plate 5 and the rotating plate 6, the cleaning cloth 10 can be driven to clean the pressure needle by operating the annular plate 5 and the rotating plate 6 respectively. The collection box 8 can receive the fallen debris, preventing the debris from falling onto the surface of the test stage 4 and reducing the interference of impurities on the subsequent test results. The operation is simple and does not delay the test process, which improves the testing efficiency of stress cone samples and thus improves the use effect of the test device.

[0047] Example 1 (for reference) Figure 2 )

[0048] When the rotating plate 6 is a convex ring plate, the convex ring plate has a simple structure, no complex grooves, and a smooth fit with the inner wall of the collection box 8. It is not easy to get stuck when rotating, and can be quickly taken out from the top of the collection box 8, which is suitable for scenarios where the cleaning cloth 10 needs to be replaced frequently and quickly.

[0049] Example 2 (for reference) Figure 4 )

[0050] When the rotating plate 6 is a convex ring plate with an annular groove on the outer surface, the annular groove on the outer surface and the limiting screw 19 form a rigid limit, ensuring the alignment accuracy of the cleaning cloth 10 and the pressure needle during cleaning. The annular groove structure added on the basis of the convex ring plate improves the stability of the device through mechanical limiting.
