Description

Technical Field

[0001] This invention relates to the field of power cable testing technology, specifically to power cable fault detection technology. Background Technology

[0002] Power cables play a vital role in power systems, primarily used for transmitting electricity. During circuit design and construction, various factors must be considered, including the electrical characteristics, mechanical properties, corrosion resistance, and durability of the cables.

[0003] Cables that operate outdoors for extended periods will inevitably experience insulation aging, reducing the insulation coverage of the copper core and potentially leading to core breakage. Early identification and rapid repair of the break point are crucial to prevent power outages for residents and production disruptions for factories, resulting in significant economic losses. Therefore, regular return-to-factory inspection and maintenance are necessary. Currently, fault detection in power cables typically involves workers cutting open the insulation to locate the break point, increasing labor costs. While commonly used cable fault detection devices can detect break points and pinpoint faults, they are bulky, difficult to move, and lack operational flexibility. They also cannot separately screen and collect substandard cables, resulting in low detection efficiency. Therefore, a new power cable fault detection technology is needed in the market.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses a conveying assembly to clean and transport cables. When the rotating rod controls the rotation of the cleaning cloth, it drives the cable to rotate. When the inclined rod pulls the driven rod forward, the cleaning cloth controls the transport of the cable. With the cooperation of the rotating plate, the cable automatically falls onto the surface of the clamping frame for inspection. When the driven rod moves to the right to control the cleaning cloth to wrap the cable, the cleaning cloth makes full contact with the cable and wipes the surface of the insulation. During cleaning, if the internal copper core is broken, the cable rotation will cause the copper core to rotate centrifugally. Since the insulation of the cable surface is less effective due to aging than when it was manufactured, the broken copper core will move to both sides under centrifugal rotation, further improving the inspection effect of the inspection assembly on the cable. 2. This invention performs cable inspection by setting up a clamping component and a detection component. Under the limiting action of the limiting rod on the sliding plate, the left and right support frames are controlled to move towards and away from each other by controlling the reciprocating rotation of the guide plate. When the left and right support frames move towards each other, the left and right clamping frames clamp the cable on both sides. The drive shaft controls the moving plate to move forward through the inclined groove. The mounting frame pushes the middle of the cable forward to perform fault detection. If the copper core inside the cable is broken, the insulating rubber ring on the surface of the cable is prone to wrinkles during the stretching process, thereby realizing the detection of copper core breakage inside the cable and effectively reducing manual labor. 3. This invention uses a guide rod to collect and differentiate cables. After testing, the clamp releases its grip on both sides of the cable. The left and right sides of the cable spring back to their original position after being released from the clamp. Cables that meet the quality standards spring forward and return to a straight state. Then, under the limit of the guide rod, they fall to the front of the partition. Cables that do not meet the quality standards cannot return to their original position after resetting because the rubber insulator outside the broken copper core is stretched. They are bent and when they come into contact with the guide rod, the bent part of the stretched rubber insulator rests on the surface of the guide rod. Then, under the tilting guidance of the guide rod, they slide to the rear of the partition, thereby realizing the collection and differentiation of cables that do not meet the quality standards.

[0025] like Figure 4 As shown, the conveying assembly 100 includes a rotating rod 104 and a sealing frame 108. The rotating rod 104 is rotatably connected to the inside of the housing 1. A driven wheel 103 is fixedly connected to the right end face of the rotating rod 104. A driving wheel 101 is fixedly connected to the output end of the first motor 5. The driving wheel 101 is connected to the driven wheel 103 via a belt 102. A cleaning cloth 105 is movably connected to the surface of the rotating rod 104.

The lower end of the sealing frame 108 is located on the upper side of the middle of the cleaning cloth 105.

[0026] Furthermore, the diagonal member 307 is located behind the driven member 106, as... Figure 2 As shown, vertical grooves 7 and horizontal grooves 10 are fixedly provided on both the left and right sides of the housing 1. The driven rod 106 moves inside the horizontal groove 10, and the lower end of the sealing frame 108 and the mating rod 107 both move inside the vertical groove 7.

[0027] Furthermore, a partition 3 is fixedly connected to the lower inner side of the housing 1, and a guide rod 4 is fixedly connected to the upper side of the partition 3 inside the housing 1. The guide rod 4 is inclined backward, and the support plate 214 is inclined forward.

[0028] Working principle: After the device is installed, the cable to be tested is placed in the conveyor rack 2. The control switch is turned on, and the output end of the first motor 5 drives the active rotating wheel 101 fixedly connected to it to rotate. The active rotating wheel 101 drives the driven rotating wheel 103 to rotate through the belt 102. The driven rotating wheel 103 drives the rotating rod 104 fixedly connected to it to rotate. The rotating rod 104 drives the cleaning cloth 105 on the surface to rotate. The driven rod 106 wipes and cleans the surface of the cable. The output end of the second motor 6 drives the output shaft 201, which is fixedly connected to it, to reciprocate. The output shaft 201 drives the guide plate 202, which is fixedly connected to it, to reciprocate. The guide plate 202 drives the connecting rods 203, which are rotatably connected to the left and right sides, to move in opposite directions. The connecting rods 203 drive the sliding plate 204, which is rotatably connected to them, to slide on the surface of the limiting rod 9, thereby realizing the linear directional and separating motion of the left and right sliding plates 204. The sliding plate 204 drives the bearing frame 205, which is fixedly connected to it, to reciprocate left and right. The bearing frame 205 drives the drive gear 206, which is rotatably connected to it, to move within the fixed groove 207. The drive gear 206 drives the front transmission gear 209 to rotate under the meshing transmission of the rack 208. The front transmission gear 209 drives the rear transmission gear 209 to rotate in the opposite direction. The transmission gear 209 drives the hinge frame 211 to rotate through the connecting plate 210. The hinge frame 211 drives the clamping frame 212 to rotate under the cooperation of the mating frame 216. The rear clamping frame 212 and the front clamping frame 212 move in opposite directions synchronously, so that the front and rear clamping frames 212 move towards each other and away from each other, thereby realizing the clamping work of the cable. The rear clamping frame 212 drives the push rod 213 fixedly connected to it to move. The support frame 205 drives the drive plate 301 fixedly connected to it to reciprocate left and right. The drive plate 301 drives the drive shaft 302 fixedly connected to it to reciprocate left and right. The drive shaft 302 controls the moving plate 303 to reciprocate back and forth by sliding in the inclined groove 304. When the moving plate 303 moves forward, it drives the mating block 306 to move forward. The mating block 306 drives the connecting spring 308 fixedly connected to it to move. When the tension of the mating block 306 exceeds the limit force of the connecting spring 308, the connecting spring 308 pulls the mounting frame 305 to move forward, thereby buffering during the stretching and preventing the mounting frame 305 from directly pulling the cable and causing internal damage. The left and right sides of the cable are kept in a limited position under the support of the clamping frame 212. The middle part of the cable moves forward under the drive of the mounting frame 305. By stretching the middle part of the cable to detect faults, if the internal copper core is broken, the rubber ring on the surface of the cable will wrinkle. If the internal copper core is normal, the surface of the cable will not change. After the current cable inspection is completed, the mounting bracket 305 moves backward, and the left and right clamping brackets 212 move to the right while releasing the clamps on both sides of the cable. At this time, the middle part of the cable on the surface of the mounting bracket 305 is located in front of the left and right sides. After the left and right sides of the cable are released from the clamping brackets 212, they spring back. The qualified cables spring forward and return to a straight state. Then, under the limit of the guide rod 4, they fall to the front of the partition 3. The unqualified cables are wrinkled during the inspection and are bent after the cables are reset. When the cables come into contact with the guide rod 4, the bent part of the cables rests on the surface of the guide rod 4. Then, under the inclined guidance of the guide rod 4, they slide to the rear of the partition 3, thereby realizing the collection of unqualified cables. When the left and right clamping frames 212 move toward the inner center of the housing 1, the rear clamping frame 212 drives the push rod 213 to swing. The rotating plate 215 rotates under the push of the push rod 213. At this time, the mounting frame 305 drives the fixed shaft 309 fixedly connected to it to move forward. The fixed shaft 309 drives the inclined rod 307 to move forward and pushes the driven rod 106 to move to the left. When the driven rod 106 moves to the left, it pulls the cleaning cloth 105 to move. After the cable loses its limit, it is transported to the surface of the support plate 214. At this time, the rotating plate 215 limits the cable. When the cleaning cloth 105 moves to the left, it drives the sealing frame 108 to move downward. The upper side of the sealing frame 108 controls the orderly transport of the cable in the conveying frame 2. As the clamping frame 212 gradually releases its grip, the rotating plate 215 rotates under the push of the push rod 213. After the cable on the surface of the support plate 214 loses its limit, it rolls to the surface of the clamping frame 212 for the next set of clamping work. At the same time, the driven rod 106 moves to the right to control the cleaning cloth 105 to fully wrap the next set of conveyed cables. The cleaning cloth 105 rotates while wrapping the cables, thereby cleaning the surface of the cables. The cables rotate under the friction transmission of the cleaning cloth 105, and the copper core inside the cables rotates accordingly. If the copper core inside the cables is broken, the broken cables gradually move to both sides under the centrifugal force of the cable rotation, thereby amplifying the defects of the cables and improving the detection effect of the detection component 300 on the cables.
