Description

Technical Field

[0001] This invention relates to the field of cable testing technology, and in particular to a device for detecting damage to power cables. Background Technology

[0002] Power cables are cables used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power plant lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. The basic structure of a power cable consists of four parts: the conductor, the insulation layer, the shielding layer, and the protective layer. The insulation layer electrically isolates the conductor from the ground and from conductors of different phases, ensuring the transmission of electrical energy. It is an indispensable component of the power cable structure. However, due to its location, the outermost insulation layer is also the most vulnerable to damage. Therefore, it needs to be inspected for damage before being put into use. Only after the inspection is completed and the cable is deemed safe to use.

[0003] According to the search, Chinese patent number CN117054432A discloses a power cable damage detection device, including a base, a support plate fixedly installed on the base, a rotating ring rotatably installed in the middle of the support plate, a power component for driving the rotating ring to rotate on the side of the support plate, and fixed plates fixedly installed inside the rotating ring along the radial direction of the rotating ring and spaced apart, with a winding roller rotatably installed on the end of the fixed plates away from the rotating ring.

[0004] The aforementioned public document describes a method for detecting cable damage: first, the cable is cleaned and dusted, and then it is spread out using a winding roller. If there is damage on the outer surface of the spread cable, it is easier to detect. Although this method can improve the accuracy of cable damage detection to some extent, in actual use, the cable is only spread out radially by the winding roller. That is, damage on the outer wall perpendicular to the cable axis is easier to be spread out and detected, but damage parallel to the cable axis is difficult to be spread out using this method. Therefore, it has limitations in detecting cable damage.

[0005] To address the aforementioned problems, this application proposes a power cable damage detection device. Summary of the Invention

Multiple air outlets are fixedly connected to the inner wall of the annular vent pipe. A fan is fixedly connected to the front of the cleaning box. An air duct is fixedly connected between the annular vent pipe and the air outlet of the fan.

[0013] Preferably, the bidirectional capture mechanism includes an H-shaped bracket, which is fixedly connected to the inner wall of the hollow cylinder. A shaft is fixedly connected to the inside of the H-shaped bracket near the center of the hollow cylinder. A U-shaped cover is fixedly connected to the outer end of the shaft. An installation wheel is movably connected to the outer end of the shaft. The installation wheel is located inside the U-shaped cover. Three adaptive mechanisms are fixedly installed on the outer end of the installation wheel. Auxiliary brackets are installed on both sides of the U-shaped cover.

[0014] Preferably, a camera and multiple fill lights are fixedly installed on the side of the internal crossbeam of the H-shaped bracket near the cable. The camera is located between the multiple fill lights. A notch is opened on the side of the U-shaped cover near the camera. An outward flipping mechanism is installed inside the notch. The number of outward flipping mechanisms is set to two, and the two outward flipping mechanisms are located on the front and rear sides of the cable, respectively.

[0015] Preferably, the adaptive mechanism includes a ring rod that surrounds the outer end of a shaft. A plurality of fixed posts are fixedly connected between the ring rod and the shaft. A plurality of spherical wheels are sleeved on the outer end of the ring rod. The ring rod and the fixed posts are movably connected, and the plurality of fixed posts and the plurality of spherical wheels are distributed in a crisscross pattern.

[0019] Compared with related technologies, the power cable damage detection device provided by the present invention has the following advantages:

[0020] 1. When cleaning cables using the cable cleaning device, no external drive equipment is required. The self-cleaning mechanism can be operated by pulling the cable to rotate the guide wheel and brush the outer surface of the cable. After brushing, the cable can be cleaned by the cooperation of the squeegee mechanism and the air drying mechanism to remove residual moisture for the next step of damage detection. If the cable is damaged during cleaning, the white cleaning solution will remain in the gaps of the cable damage and will not be easy to remove, which helps to accurately capture the image of the damage.

[0021] 2. When detecting cable damage using a multi-directional capture device, three bidirectional capture mechanisms are used to capture images of the cable's outer wall at a certain angle. When the mounting wheel bends the cable radially, three adaptive mechanisms prevent the cable from twisting. In addition, two outward-folding mechanisms distributed on both sides of the cable axially expand the cable's outer wall, thereby achieving bidirectional capture of the cable's damage images in both the radial and axial directions. The three bidirectional capture mechanisms can capture images of the cable's outer surface from over 360 degrees, which is sufficient to cover the entire outer surface of the cable, resulting in better damage detection and higher detection accuracy.

[0034] Please see Figure 1-11 The technical solution provided by the present invention specifically includes the following embodiments:

[0035] Example 1: A power cable damage detection device, comprising a cable 1, a cable cleaning device, and a multi-directional capture device, wherein the cable 1 passes through the cable cleaning device and the multi-directional capture device sequentially from left to right;

[0036] The cable cleaning device includes a cleaning box 2. A drain pipe 21 is fixedly connected to the bottom of the cleaning box 2 on the side away from the hollow cylinder 3. A valve is installed on the drain pipe 21. Two fixing ears 22 are fixedly connected to the bottom of both the front and rear sides of the cleaning box 2. Multiple guide wheels 4 are movably connected inside the cleaning box 2 through a rotating shaft. The guide wheels 4 are used to guide the cable 1 for arrangement. A self-cleaning mechanism 5, a water scraping mechanism 6, and a drying mechanism 7 are installed inside the cleaning box 2. The self-cleaning mechanism 5, the water scraping mechanism 6, and the drying mechanism 7 are sequentially sleeved on the cable 1 from left to right.

[0037] The cleaning solution in the cleaning tank 2 can be cleaning water with added white substance. Since the outer surface of the cable 1 is usually black, after the cleaning solution cleans the dirt and dust off the outer surface of the cable 1, if there is any damage to the cable 1, the white water will seep into the damaged area. This will make it easier to detect when the multi-directional capture device detects damage to the outer surface of the cable 1. Even if the drying mechanism 7 dries the white cleaning water that has seeped into the damaged area, there will still be white substance remaining in it, which can still help detect the damaged area of ​​the cable 1.

[0038] The drain pipe 21 and valve can drain the cleaning liquid from the cleaning tank 2, and the fixing lug 22 can be used to support and fix the cleaning tank 2 to maintain its stability.

[0039] The self-cleaning mechanism 5 includes a support base 51, which is fixedly connected to the bottom of the cleaning tank 2. A sleeve 52 is movably connected to the support base 51 and is fitted onto the outer end of the cable 1. Multiple bristles 53 are fixedly connected to the inner wall of the sleeve 52, and the ends of the bristles 53 are in contact with the outer end of the cable 1. A toothed ring 54 is fixedly connected to the outer end of the sleeve 52. A transmission rod 55 is movably connected to the front side of the inside of the cleaning tank 2 through a bearing seat. One end of the transmission rod 55 is fixedly connected to the outer end of the shaft of one of the guide wheels 4 with bevel gears 56. The two bevel gears 56 mesh with each other. The other end of the transmission rod 55 is fixedly connected to a first gear 57, which is located in front of the toothed ring 54, and the toothed ring 54 and the first gear 57 mesh with each other.

[0040] When detecting damage to cable 1, cable 1 only needs to be pulled to continuously pass through the cable cleaning device and the multi-directional capture device. The guide wheel 4 in the cable cleaning device can rotate with the movement of cable 1 to guide cable 1, so that part of cable 1 is immersed in the white cleaning water inside the cleaning tank 2. During this period, when a guide wheel 4 adjacent to the self-cleaning mechanism 5 rotates, the bevel gear 56 on its end shaft will mesh with the bevel gear 56 on the transmission rod 55 to achieve transmission and drive the transmission rod 55 to rotate. When the transmission rod 55 rotates, it will drive the sleeve 52 to rotate on the support base 51 through the meshing of the first gear 57 and the gear ring 54. Since the sleeve 52 is sleeved on cable 1, when the sleeve 52 rotates, the outer surface of cable 1 can be brushed by the brush bristles 53 to remove dirt and dust that may block the outer surface of cable 1. The faster the cable 1 moves, the faster the self-cleaning mechanism 5 cleans.

[0041] The wiping mechanism 6 consists of a wide-mouth wiping cover 61 and two fixing rods 62. The two fixing rods 62 are fixedly connected to the front and rear sides of the wide-mouth wiping cover 61, and the ends of the fixing rods 62 are fixedly connected to the inner wall of the cleaning tank 2. The wide-mouth wiping cover 61 is sleeved on the outer end of the cable 1, and the inner wall of the narrow end of the wide-mouth wiping cover 61 is in contact with the outer wall of the cable 1.

[0042] At least two wiper mechanisms 6 are provided, so that multiple wide-mouth wiper covers 61 can scrape off the residual cleaning fluid on the surface of the cable 1 after the cable 1 is pulled out of the cleaning fluid, and the scraped cleaning fluid will fall back into the cleaning tank 2 for continued use.

[0043] The air drying mechanism 7 includes an annular vent pipe 71, which is sleeved on the outer end of the cable 1. Fixing brackets 73 are fixedly connected to the front and rear sides of the annular vent pipe 71 and the front and rear sides of the inside of the cleaning box 2. Multiple air outlets 72 are fixedly connected to the inner wall of the annular vent pipe 71. A fan 75 is fixedly connected to the front side of the cleaning box 2. An air duct 74 is fixedly connected between the annular vent pipe 71 and the air outlet of the fan 75.

[0044] After the cleaning fluid remaining on the surface of cable 1 is repeatedly scraped off by multiple scraping mechanisms 6, the drying mechanism 7 blows out vortex-shaped air to quickly dry the moisture on the surface of cable 1. Cable 1 passes through an annular vent pipe 71, and multiple air outlets 72 on the inner wall of the annular vent pipe 71 are arranged in a ring array and are also inclined. When the fan 75 blows air into the annular vent pipe 71 through the air duct 74, the air sprayed by the multiple air outlets 72 blows out in a vortex shape towards the outer surface of cable 1 inside the annular vent pipe 71. The overall air outlet direction is to the left, that is, against the direction in which cable 1 is pulled. The vortex-shaped air can quickly dry the residual moisture on the outer surface of cable 1. If the cleaning fluid that seeped into the damaged area of ​​cable 1 is also dried, the white substance in the cleaning fluid will remain at the damaged area. If it is not dried, the seeped cleaning fluid will still be white. Ultimately, the multi-directional capture device can be used to capture and detect the damaged area on the surface of cable 1.

[0045] Example 2: The multi-directional capture device includes a hollow cylinder 3, with a base 31 fixedly connected to the bottom of the hollow cylinder 3. The hollow cylinder 3 is located on one side of the cleaning tank 2. Three bidirectional capture mechanisms 8 are fixedly installed inside the hollow cylinder 3 from left to right, and the three bidirectional capture mechanisms 8 are arranged in a circular array around the central axis of the hollow cylinder 3.

[0046] The hollow cylinder 3 facilitates the installation of three circular arrays of bidirectional capture mechanisms 8 distributed from left to right. The hollow design of the hollow cylinder 3 reduces material waste without affecting its strength. At the same time, some of its internal conditions can be seen through the hollow parts. The base 31 is used to support and fix the hollow cylinder 3.

[0047] The bidirectional capture mechanism 8 includes an H-shaped bracket 81, which is fixedly connected to the inner wall of the hollow cylinder 3. A shaft 84 is fixedly connected to the inside of the H-shaped bracket 81 near the center of the hollow cylinder 3. A U-shaped cover 85 is fixedly connected to the outer end of the shaft 84. An installation wheel 86 is movably connected to the outer end of the shaft 84. The installation wheel 86 is located inside the U-shaped cover 85. Three adaptive mechanisms 87 are fixedly installed on the outer end of the installation wheel 86. Auxiliary brackets 89 are installed on both sides of the U-shaped cover 85.

[0048] In the bidirectional capture mechanism 8, only the mounting wheel 86 and the three adaptive mechanisms 87 mounted on its surface can rotate, while the rest of the components are fixed. The purpose is to bend and guide the cable 1 when it is pulled, thereby achieving radial expansion of the cable 1. If there are radial cracks or damage on the cable 1, they can be easily captured and detected.

[0049] A camera 82 and multiple fill lights 83 are fixedly installed on the side of the internal crossbeam of the H-shaped bracket 81 near the cable 1. The camera 82 is located between the multiple fill lights 83. A notch 851 is opened on the side of the U-shaped cover 85 near the camera 82. An outward flipping mechanism 88 is installed inside the notch 851. The number of outward flipping mechanisms 88 is set to two, and the two outward flipping mechanisms 88 are located on the front and rear sides of the cable 1, respectively.

[0050] The camera 82 is positioned directly at the peak of the cable 1 that is bent and guided, while the supplementary light 83 also provides supplementary lighting to this area. After the cable 1 is bent and guided, the break at the peak will be opened up, and the camera 82 can quickly capture the break.

[0051] The adaptive mechanism 87 includes an annular rod 871, which surrounds the outer end of the shaft 84. A plurality of fixed posts 872 are fixedly connected between the annular rod 871 and the shaft 84. A plurality of spherical wheels 873 are sleeved on the outer end of the annular rod 871. The annular rod 871 and the fixed posts 872 are movably connected, and the plurality of fixed posts 872 and the plurality of spherical wheels 873 are distributed in a cross pattern. The outer end of the spherical wheel 873 is in contact with the outer wall of the cable 1.

[0052] There are three adaptive mechanisms 87, and the inner diameter of the one closest to the middle of the three adaptive mechanisms 87 is smaller. This allows the three adaptive mechanisms 87 to fit and support the arc surface of the cable 1 when arranged, preventing the cable 1 from detaching from the mounting wheel 86 when being pulled. The spherical wheel 873 in the adaptive mechanism 87 can rotate along the ring rod 871. In this way, if the cable 1 is twisted, the spherical wheel 873 in contact with the cable 1 can rotate with it, causing the cable 1 to straighten itself and preventing further twisting. This ensures that the images captured by each bidirectional capture mechanism 8 on the cable 1 are parallel to the axis of the cable 1. The three bidirectional capture mechanisms 8 work together to achieve image capture of the cable 1 at more than 360 degrees, which can more comprehensively detect the damage to the cable 1.

[0053] The outward turning mechanism 88 includes a friction wheel 881, which is movably connected inside the notch 851 via a rotating shaft. The outer end of the friction wheel 881 is in contact with the outer wall of the cable 1. A motor 882 is fixedly connected to the outer wall of the U-shaped cover 85. The output shaft of the motor 882 and the outer end of the rotating shaft of the friction wheel 881 are both fixedly connected to a second gear 883, and the two second gears 883 mesh with each other.

[0054] When cable 1 is bent and guided, there is an outward turning mechanism 88 on each side of the bend peak. The friction wheel 881 in the outward turning mechanism 88 continuously rotates against the outer surface of cable 1. The two friction wheels 881 continuously rotate relative to cable 1, thereby causing the outer surface of the bend peak of cable 1 to be opened to both sides. At this time, if there are cracks or other damages in the axial direction, they can be easily opened by the two outward turning mechanisms 88 and then detected by camera 2. It is worth mentioning that when the friction wheel 881 rotates against cable 1, there is only a large friction between the two, but the friction wheel 881 can still rotate normally, and it will not affect the axial traction movement of cable 1.

[0055] The auxiliary support 89 consists of a guide ring 891 and two connecting arms 892. The connecting arms 892 are fixedly connected to the guide ring 891 on the side near the U-shaped cover 85, and the two connecting arms 892 are respectively fixedly connected to the front and rear sides of the U-shaped cover 85 by bolts.

[0056] The guide ring 891 in the auxiliary bracket 89 allows the cable 1 to be guided in a curved manner when it is inside the bidirectional capture mechanism, while it can still be guided horizontally when it is on both sides.

[0057] Figure 11 The camera 82 in the three bidirectional capture mechanisms 8 is used to capture a simulated image of the angle of the outer surface of the cable 1. The three bidirectional capture mechanisms 8 can ultimately achieve more than 360 degrees of coverage of the outer surface of the cable 1 to capture images from multiple directions to detect the damage to the cable 1. Compared with single radial detection and detection methods that cannot ensure whether the cable 1 is twisted or pulled, this detection method has fewer limitations and is more accurate and comprehensive.

[0058] Working principle:

[0059] As the cable 1 passes through the inside of the cleaning tank 2, it is guided by multiple guide wheels 4. The two bottommost guide wheels 4 ensure that part of the cable 1 is in the cleaning liquid inside the cleaning tank 2, so that the cable 1 is brushed by the self-cleaning mechanism 5 when it is immersed in the cleaning liquid. After brushing, the cable 1 floats to the surface of the water as it continues to move. During this process, the water adhering to the outer wall is scraped off by two scraping mechanisms 6. Then, when it passes through the inside of the annular vent pipe 71, the residual moisture is dried by the vortex air blown out from multiple air outlets 72.

[0060] After being cleaned, the cable 1 enters the hollow cylinder 3 and passes through three bidirectional capture mechanisms 8 in sequence. Each bidirectional capture mechanism 8 simultaneously expands the cable 1 radially and axially and captures images to identify any damage. As the cable 1 passes through the bidirectional capture mechanisms 8, it is guided by two guide rings 891 and bent by the mounting wheel 86. When bent, the cable 1 adheres to the three adaptive mechanisms 87 on the outside of the mounting wheel 86. The spherical wheel 873 on the adaptive mechanism 87 can rotate and contact the outer wall of the cable 1. At this time, regardless of the angle of the bidirectional capture mechanism 8, the cable 1 remains in contact with the outer wall of the cable. When cable 1 is bent, cable 1 will not twist. The spherical wheel 873 can support cable 1 while adapting to its radial direction to maintain its natural radial state. When cable 1 is bent, the outer wall is radially stretched. At the same time, the friction wheels 881 in the two outward flipping mechanisms 88 will also rub against the outer wall of cable 1 and rotate, thereby stretching the bearing of the outer wall of cable 1. If there is a damaged part on cable 1, the camera 82 can directly capture the image of the damaged part. The three bidirectional capture mechanisms 8 ultimately capture the image of the outer wall of cable 1 at an angle of more than 360 degrees, which is sufficient to cover all parts of the outer wall of cable 1.
