Description

Technical Field

[0001] This utility model relates to the field of wear detection technology, and in particular to a contact wire wear detection device. Background Technology

[0002] The internal conductors of the overhead contact line busbar are core components of the rail transit power supply system. Exposed to complex outdoor environments for extended periods, their surfaces are prone to accumulating dust, oil, and other contaminants. The degree of wear on these conductors directly impacts power supply stability and operational safety. Therefore, regular wear testing of the conductors is necessary. The core principle is to accurately measure linearly related parameters such as wear thickness and wear profile to determine the conductor's condition and lifespan. Currently, most existing overhead contact line wear testing devices directly inspect the conductors without a dedicated pre-treatment cleaning mechanism. Contaminants on the conductor surface can obscure the testing area, preventing accurate identification of wear marks and resulting in significant data deviations and low accuracy. While some devices incorporate simple cleaning structures, they only perform preliminary wiping of the conductor surface, failing to promptly remove contaminants from cleaning components and potentially causing secondary contamination. Therefore, we propose an overhead contact line wear testing device. Utility Model Content

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1 - Figure 4 As shown, a contact wire wear detection device includes a busbar 1. A cleaning mechanism 2 is provided at the bottom of the busbar 1. The cleaning mechanism 2 includes a detection box 201. A cleaning box 202 is fixedly connected to the outer surface of the detection box 201. A cleaning rod 203 is rotatably connected to the inner surface of the cleaning box 202 via a bearing. A cleaning brush 204 is fixedly connected to the outer surface of the cleaning rod 203. Two limiting rods 206 are fixedly connected to the outer surface of the cleaning box 202. A sliding block 207 is slidably connected to the outer surface of the two limiting rods 206. A scraper 208 is fixedly connected to the outer surface of the sliding block 207. The scraper 208 contacts the cleaning brush 204.

[0021] The effect achieved by the entire embodiment 1 is that the cleaning brush 204 on the outer surface of the cleaning rod 203 rotates synchronously to wipe and clean the surface of the line to be tested inside the manifold 1. The sliding block 207 slides back and forth along the limiting rod 206, thereby driving the scraper 208 to continuously contact the cleaning brush 204, scraping off the stains attached to the surface of the cleaning brush 204, and avoiding secondary contamination of the line inside the manifold 1 by the stains.

[0022] Example 2, as Figure 1 - Figure 4As shown, a rotating rod 3 is rotatably connected to the upper surface of the cleaning box 202 via a bearing. A rotating plate 4 is fixedly connected to the outer surface of the rotating rod 3. A locking block 5 is fixedly connected to the upper surface of the rotating plate 4. A limit frame 6 is fixedly connected to the lower surface of the sliding block 207. The locking block 5 and the limit frame 6 are slidably connected. A connecting rod 7 is rotatably connected to the inner surface of the cleaning box 202 via a bearing. Bevel gears 8 are fixedly connected to the outer surfaces of both the connecting rod 7 and the rotating rod 3. The two bevel gears 8 are meshed together. A wear detection probe 9 is fixedly installed on the upper surface of the detection box 201. A wear detection probe 9 is fixedly installed on the outer surface of the detection box 201. Multiple connecting frames 10 are fixedly connected. Multiple support rods 11 are rotatably connected to the outer surfaces of the multiple connecting frames 10 via shafts. Rollers 12 are fixedly connected to the outer surfaces of the multiple support rods 11. The multiple rollers 12 are movably connected to the busbar 1. A first motor 13 is fixedly connected to the outer surface of one of the connecting frames 10. The output end of the first motor 13 is fixedly connected to the support rod 11. The cleaning rod 203 is connected to the connecting rod 7 via synchronous belt drive. A second motor 14 is fixedly connected to the outer surface of the cleaning box 202. The output end of the second motor 14 is fixedly connected to the cleaning rod 203.

[0023] The overall effect of embodiment 2 is as follows: the first motor 13 drives the support rod 11 to drive the roller 12 to roll, realizing the smooth movement of the device along the busbar 1; the second motor 14, the output end of which drives the cleaning rod 203 to rotate; the cleaning rod 203 drives the connecting rod 7 to rotate through the synchronous belt; the connecting rod 7 and the rotating rod 3 are linked through the meshing bevel gear 8; the rotating rod 3 drives the rotating plate 4 to rotate; the locking block 5 on the rotating plate 4 slides in the limiting frame 6 on the lower surface of the sliding block 207, driving the sliding block 207 to slide back and forth along the limiting rod 206; after cleaning is completed, the wear detection probe 9 fixedly installed on the upper surface of the detection box 201 is activated to detect the wear parameters of the cleaned line inside the busbar 1.

[0024] Working principle: During operation, the rollers 12 on the connecting frame 10 are in contact with the busbar 1. The first motor 13 drives the support rod 11 to rotate the rollers 12, enabling the device to move smoothly along the busbar 1. The second motor 14 is started, and its output end drives the cleaning rod 203 to rotate. The cleaning brush 204 on the outer surface of the cleaning rod 203 rotates synchronously to wipe and clean the surface of the line to be tested inside the busbar 1. At the same time, the cleaning rod 203 drives the connecting rod 7 to rotate via a synchronous belt. The connecting rod 7 and the rotating rod 3 are linked by the meshing bevel gear 8. The rotating rod 3 drives the rotating plate 4 to rotate. The upper locking block 5 slides within the limiting frame 6 on the lower surface of the sliding block 207, driving the sliding block 207 to slide back and forth along the limiting rod 206. This causes the scraper 208 to continuously contact the cleaning brush 204, scraping away the stains attached to the surface of the cleaning brush 204 and preventing secondary contamination of the wires inside the busbar 1 by the stains. After cleaning is completed, the wear detection probe 9, which is fixedly installed on the upper surface of the detection box 201, is activated to detect the wear parameters of the cleaned wires inside the busbar 1. This achieves cleaning before detection, effectively avoiding interference from stains on the detection results and improving the accuracy of the wear detection data of the wires inside the busbar 1.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
