Description

Technical Field

[0001] The present invention relates to the technical field of insulator detection, in particular to an insulation test device and method for a grounding insulator. Background Art

[0002] As the name suggests, a grounding insulator is an electrical component that maintains both insulation and grounding properties. It is typically installed between power facilities and the earth. Its purpose is to conduct electrical charge from the facility to the earth under specific circumstances, preventing potential safety incidents caused by charge accumulation. The test device is a specialized device used to test the insulation performance of grounding insulators.

[0003] Reference is made to a patent application with publication number CN118914787A, which discloses an apparatus and method for detecting insulators. Several detection mechanisms are provided above the support box, and two detection probes for detecting insulators are fixedly connected to the detection mechanisms. Loading trays are symmetrically provided on both sides of the detection mechanism, and a receiving groove for supporting the bottom end of the insulator is provided on the top of the loading tray, and the depths of two adjacent receiving grooves are inconsistent. The support box is equipped with a spacing adjustment structure for adjusting the position of the loading tray, and the support box is equipped with a damping adjustment component for driving the detection mechanism to lift and rotate.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See Figure 1-Figure 7 The present invention discloses a grounding insulator insulation test device and provides the following three technical solutions:

[0035] The first embodiment includes a fixed cylinder 1 and further includes:

[0036] The detection mechanism 2 is arranged on the top surface of the fixed cylinder 1 and is used to detect the insulation of the test insulator. The left and right ends of the top surface of the fixed cylinder 1 are movably mounted with movable disks 29. The top surface of the movable disk 29 is fixedly mounted with a fixed column 28. The top surface of the fixed column 28 is movably mounted with a connecting disk 23. The top surface of the connecting disk 23 is fixedly mounted with a detection device 21 for detecting the insulation of the insulator. The detection device 21 is an existing device with the same specifications as the detection component in the comparative document. It will not be described in detail here. Two detection probes 22 for detecting insulators are fixedly mounted on one side of the detection device 21. A buffer component is provided on the outer side of the connecting disk 23 to prevent the detection mechanism 2 from causing excessive squeezing of the insulator during detection, thereby causing damage to the detection mechanism 2;

[0037] A fixing mechanism 3 is provided on the top surface of the fixing cylinder 1 for fixing the position of the insulator;

[0038] The driving assembly 4 is arranged inside the fixed cylinder 1 and is used to drive the detection mechanism 2 to rotate and lift to detect different height positions of the insulator. The buffer assembly includes an arc-shaped groove 24 opened on the outside of the fixed column 28. A slider 26 is slidably installed inside the arc-shaped groove 24, and the cross-section of the slider 26 is convex. A connecting plate 27 is fixedly installed on the outside of the slider 26. One end of the arc-shaped groove 24 is fixedly installed with a first spring 25 that fixes the position of the slider 26. The outer side of the slider 26 moves through the interior of the arc-shaped groove 24 and is fixedly installed on one side of the connecting plate 27. The top surface of the connecting plate 27 is fixedly installed with the bottom surface of the connecting disk 23. One end of the first spring 25 is fixedly installed on one side of the slider 26, and the elastic force of the first spring 25 will push the slider 26 to drive the connecting plate 27 to move and fix the position of the detection device 21. When the detection probe 22 is subjected to excessive pressure, the detection device 21 will be driven to rotate through the slider 26 to prevent the detection probe 22 from being excessively squeezed and damaged.

[0039] The connection plate 23 and the first spring 25 are provided to prevent the detection probe 22 from being damaged by excessive squeezing. During use, the detection mechanism 2 is driven by the driving component 4 to be close to the outside of the insulator to perform an insulation detection test. When the detection probe 22 is subjected to excessive pressure, the slider 26 will drive the detection device 21 to rotate, so as to prevent the detection probe 22 from being damaged by excessive squeezing. When the detection probe 22 leaves the outside of the insulator, the elastic force of the first spring 25 will push the slider 26 to drive the connecting plate 27 to move, so that the detection device 21 and the detection probe 22 are reset to facilitate the next detection, thereby causing unnecessary damage that affects the subsequent use effect of the detection probe 22.

The bottom surface of the clamping plate 34 is used to limit the moving trajectory of the clamping plate 34. The cross-section of the placement groove 35 is arc-shaped. The clamping plate 34 for clamping and fixing the insulator is movably installed inside the placement groove 35. An adjusting screw 36 for fixing the position of the clamping plate 34 is movably installed on one side of the clamping plate 34. The adjusting screw 36 is threaded away from the end of the clamping plate 34 and passes through the interior of the placement groove 35 and extends to the outside of the carrier tube 33. One end of the second spring 32 is fixedly mounted on one side of the movable block 37, and the rotating adjusting screw 36 drives the clamping plate 34 to move to clamp and fix the insulator in the carrier tube 33.

[0041] The provided carrying tube 33 and clamping plate 34 facilitate the fixing of insulators of different sizes and specifications. When in use, the bottom end of the insulator is inserted into the inside of the carrying tube 33, and then the adjusting screw 36 is rotated to drive the clamping plate 34 to move through the carrying tube 33 to clamp the insulator for fixing. The structure is simple and convenient.

[0042] The third embodiment is mainly different from the second embodiment in that: the driving component 4 includes a movable screw 45 movably installed inside the fixed cylinder 1, a DC motor 46 for driving the movable screw 45 to rotate is fixedly installed on the bottom surface of the fixed cylinder 1, a fixed disk 44 is movably installed inside the fixed cylinder 1, and driven gear disks 41 are movably installed on the left and right sides of the top surface of the fixed disk 44, and a connecting column 42 for driving the detection mechanism 2 to rotate is fixedly installed on the top surface of the driven gear disk 41, and the outer side of the movable screw 45 is threadedly installed with a driving gear disk 43 for driving the driven gear disk 41 to rotate, and limit blocks 47 for limiting the lifting trajectory of the fixed disk 44 are fixedly installed on the left and right sides of the fixed disk 44, and limiting grooves 48 are provided on the left and right sides of the inner cavity of the fixed cylinder 1. The top of the connecting column 42 movably passes through the interior of the fixed cylinder 1 and is fixedly installed on the movable disk 2 9, the bottom surface of the driving gear plate 43 is movably mounted on the top surface of the fixed plate 44, the outer side of the driving gear plate 43 is engaged with the outer side of the driven gear plate 41, and the outer side of the limit block 47 is slidably mounted on the inside of the limit groove 48, the bottom end of the movable screw 45 movably penetrates the interior of the fixed cylinder 1 and is fixedly mounted on the output end of the DC motor 46, the top thread of the movable screw 45 penetrates the bottom surface of the fixed plate 44 and is movably mounted on the top surface of the inner cavity of the fixed cylinder 1, and the starting DC motor 46 can drive the fixed plate 44 to rise through the restriction of the limit block 47, and then the fixed plate 44 will drive the detection mechanism 2 to rise through the connecting column 42, and when the movable screw 45 rotates, it will drive the driving gear plate 43 to rotate through the driven gear plate 41 to rotate the connecting column 42, and then the connecting column 42 will drive the detection mechanism 2 to rotate to perform detection tests on positions of different heights of the insulator.

[0043] By providing the driving gear plate 43 and the fixed plate 44, the height of the detection probe 22 can be adjusted while being driven to rotate for detection. When in use, starting the DC motor 46 can drive the fixed plate 44 to rise through the restriction of the limit block 47, and then the fixed plate 44 will drive the detection mechanism 2 to rise through the connecting column 42. When the movable screw 45 rotates, it will drive the driving gear plate 43 to rotate through the driven gear plate 41 to rotate the connecting column 42, and then the connecting column 42 will drive the detection mechanism 2 to rotate to perform detection tests at different heights of the insulator, which is convenient, fast and practical.

[0044] The present invention also discloses a method for using a grounding insulator insulation test device, which specifically includes the following steps:

[0045] Step 1: Insert the bottom end of the insulator into the interior of the carrier tube 33, then rotate the adjusting screw 36 to drive the clamping plate 34 to move through the carrier tube 33 to clamp the insulator and fix it;

[0046] Step 2: Restart the DC motor 46 to drive the fixed disk 44 to rise through the restriction of the limit block 47. Then the fixed disk 44 will drive the movable disk 29 through the connecting column 42 to lift the detection device 21. At the same time, when the movable screw 45 rotates, it will drive the driving gear plate 43 to rotate through the driven gear plate 41 to rotate the connecting column 42. After the connecting column 42 drives the movable disk 29 to make the detection probe 22 close to the insulator, the DC motor 46 is turned off to perform the detection test through the detection device 21. When the detection probe 22 is subjected to excessive pressure, the detection device 21 will be driven to rotate through the slider 26 to prevent the detection probe 22 from being excessively squeezed and damaged.

[0047] Step 3. After the detection is completed, move the DC motor 46 to continue to drive the detection device 21 to rotate the detection probe 22. At this time, the detection probe 22 will push the insulator to make the movable block 37 slide in the movable groove 31. When the detection probe 22 leaves the outside of the insulator, the elastic force of the first spring 25 will push the slider 26 to drive the connecting plate 27 to move so that the detection device 21 and the detection probe 22 are reset to facilitate the next detection. After the detection device 21 and the detection probe 22 rotate one circle, they will again cling to the outside of the insulator at different heights, and insulation detection tests will be performed on the insulator at different heights.
