[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] Example:

[0034] Reference Figure 1-Figure 9A cable detection device includes a detection platform 1, and also includes: a plurality of groups of pillars 2 arranged on the detection platform 1, and a positioning wheel 3 is arranged on the pillar 2. The surface of the positioning wheel 3 is arc-shaped to ensure the stability of the cable during transportation and improve the detection effect of the cable. The cable can be transported by a winding device. During the winding process, the cable moves along the positioning wheel 3, and due to the friction between the cable and the positioning wheel 3, the positioning wheel 3 is driven to rotate. In addition, the positioning wheel 3 is preferably set to three groups, and the size detection unit is set at the positioning wheel 3 in the middle position. The cleaning mechanism 11 is far away from the winding device, and the detection mark unit is close to the winding device. In order to clean the dust on the cable surface before testing, a size detection unit is provided on the side of the testing platform 1 close to the positioning wheel 3 for detecting the size of the cable; a cleaning mechanism 11 is provided on the size detection unit, and a driving mechanism 12 is provided between the positioning wheel 3 and the size detection unit. The positioning wheel 3 can drive the cleaning mechanism 11 to rotate along the cable surface through the driving mechanism 12 to clean the cable surface; a detection marking unit is provided on the side of the size detection unit away from the cleaning mechanism 11 for marking the problem parts of the cable, wherein the detection marking unit is connected to the cleaning mechanism 11 through a pipeline.

[0035] Reference Figure 1 , Figure 2 and Figure 4 The size detection unit includes a bracket 4 fixedly connected to the side of the detection platform 1 close to the positioning wheel 3, a screw rod 5 is threadedly connected to the bracket 4, a movable plate 6 is rotatably connected to the bottom end of the screw rod 5, a detection cylinder 7 is fixedly connected to the side of the movable plate 6 away from the screw rod 5, a detection wheel 8 is arranged at the end of the detection cylinder 7 away from the movable plate 6, a first spring 9 is fixedly connected between the detection wheel 8 and the movable plate 6, wherein a slide groove 10 slidably connected to the movable plate 6 is opened on the inner side of the bracket 4, the screw rod 5 passes through the bracket 4, the first spring 9 is sleeved on the outside of the detection cylinder 7, and the detection wheel 8 matches the positioning wheel 3.

[0036] It needs to be explained that the structure of the detection cylinder 7 is similar to that of the compression assembly 128, that is, the gas will be compressed when the detection cylinder 7 extends or contracts. When the size of the cable is detected, a certain pressure is created between the detection wheel 8 and the cable by rotating the screw 5. When the size of the cable is small or large, the detection cylinder 7 will be driven to extend or contract, thereby detecting the size of the cable in real time. The bracket 4 is provided with a thread matching the screw 5, so that the screw 5 moves upward or downward when rotating, thereby adjusting the distance between the positioning wheel 3 and the detection wheel 8, so as to facilitate the detection of cables of different sizes.

[0037] Reference Figure 1 , Figure 3 , Figure 5 and Fig. 9The cleaning mechanism 11 includes a mounting plate 111 fixedly connected to the bracket 4, a limiting ring 112 fixedly connected to the mounting plate 111, a circular ring 113 is arranged on the inner side of the limiting ring 112, a positioning ring 114 slidably connected to the limiting ring 112 is fixedly connected to the outer side of the circular ring 113, a groove 115 is provided on the inner side of the circular ring 113, a cleaning ring 116 is arranged inside the groove 115, wherein an air jet ring 119 is fixedly connected to the side of the mounting plate 111 close to the limiting ring 112, the limiting ring 112, the circular ring 113, the cleaning ring 116 and the air jet ring 119 are all sleeved on the outside of the cable, and the cleaning ring 116 is in contact with the surface of the cable, and also includes a plurality of groups of vibration cylinders 117 and a second spring 118 fixedly connected between the groove 115 and the cleaning ring 116, wherein the vibration cylinder 117 and the second spring 118 are respectively located at both ends of the cleaning ring 116.

[0038] The specific structure of the cleaning ring 116 can refer to the technical solutions in the prior art. Those skilled in the art will know that it will not be elaborated here. Cleaning can be achieved by the friction between the cleaning ring 116 and the cable surface. During the cleaning process, the jet ring 119 can blow gas into the cleaning ring 116 to discharge the cleaned dust to ensure the subsequent cleaning effect of the cable. Among them, the positioning ring 114 can ensure the stability of the circular ring 113 during rotation, and during the cleaning process, by intermittently introducing gas into the vibrating cylinder 117, the cleaning ring 116 can be driven to vibrate in the circular ring 113, which can not only improve the cleaning effect on the cable surface, but also reduce the adhesion of dust on the cleaning ring 116.

[0039] Reference Figure 1 , Figure 5 , Figure 6 and Figure 8The driving mechanism 12 includes a driving bevel gear 121 fixedly connected to the shaft end of the positioning wheel 3, a rotating shaft 122 is rotatably connected between the positioning wheel 3 and the bracket 4, a driven bevel gear 123 meshing with the driving bevel gear 121 is fixedly connected to the end of the rotating shaft 122, a driving gear 124 is fixedly connected to the rotating shaft 122, a driven gear 125 meshing with the driving gear 124 is fixedly connected to the outer wall of the ring 113, and also includes a reciprocating screw 126 fixedly connected to the rotating shaft 126, a slider 127 is provided on the reciprocating screw 126, a compression assembly 128 is fixedly connected between the slider 127 and the bracket 4, wherein the compression assembly 128 and the jet ring 119 are connected to each other. The slider 127 is connected through a pipeline, and a protrusion matching the reciprocating screw 122 is arranged inside the slider 127. The compression assembly 128 includes a compression cylinder 1281 and a compression rod 1283. The compression cylinder 1281 is connected to the bracket 4, and the compression rod 1283 is connected to the slider 127. The end of the compression rod 1283 away from the slider 127 extends to the interior of the compression cylinder 1281, and the end of the compression rod 1283 away from the slider 127 is fixedly connected with a piston 1282 that fits tightly with the inner wall of the compression cylinder 1281, wherein a sealed connection is adopted between the compression rod 1283 and the compression cylinder 1281, and two groups of compression chambers are formed between the two sides of the piston 1282 and the compression cylinder 1281.

[0040] During the transportation of the cable, the driving bevel gear 121 and the driven bevel gear 123 can drive the rotating shaft 122 to rotate, thereby driving the driving gear 124 and the driven gear 125 to drive the ring 113 to rotate, and the transported cable can be cleaned in a rotational manner to avoid the situation where the cable has a cleaning dead corner, thereby further improving the cleaning effect of the cable. At the same time, the rotating shaft 122 drives the reciprocating screw 126 to rotate and drives the slider 127 to move back and forth. When the slider 127 moves to the side of the compression cylinder 1281, the compression chamber close to the side of the compression cylinder 1281 can be cleaned by the piston 1282. When the slider 127 moves to the side away from the compression cylinder 1281, the compression chamber on the other side can be compressed by the piston 1282, so as to realize continuous compression of the gas, and the compressed gas is delivered to the jet ring 119 and blown to the cleaning ring 116, so as to blow the cleaned dust out of the ring 113. On the one hand, it can avoid the cleaning effect of dust on subsequent cables, and on the other hand, it can avoid the dust from adhering to the cleaning ring 116 for a long time. Among them, the structure of the reciprocating screw 126 and the slider 127 is a conventional means in the prior art, so it is not described in detail.

[0041] Reference Figure 3 and Figure 7The detection marking mechanism includes a fixed plate 13 fixedly connected to the side of the bracket 4 away from the mounting plate 111, and a detection ring 14 and a marking box 15 are fixedly connected to the fixed plate 13. The marking box 15 is connected to a marking nozzle 17 on the side close to the cable, wherein an electric control device connected to the marking nozzle 17 is arranged inside the marking box 15, and the detection ring 14 includes a plurality of detection heads for performing appearance detection and insulation detection on the cable, and the detection heads are electrically connected to the electric control device, and also includes a connecting pipe 16 connected between the marking box 15 and the detection cylinder 7, and the connecting pipe 16 extends to the inside of the marking box 15, and a pneumatic valve is arranged on the side of the marking box 15 close to the marking nozzle 17, and the pneumatic valve is connected to the connecting pipe 16.

[0042] It should be explained that the detection heads are preferably four groups and are symmetrically arranged. The detection heads include image detection equipment and infrared detection equipment. The detection heads in symmetrical positions are of the same type of equipment. This is to ensure that there are no blind spots during detection. The electronic control device can control the opening and closing of the marking nozzle 17. This is a conventional method in the prior art and will not be elaborated on. In addition, a pneumatic valve is provided inside the marking box 15 and is connected to the connecting pipe 16. When the size of the cable is abnormal, the gas compressed by the detection cylinder 7 drives the pneumatic valve to be in an open state, and the marker in the marking box 15 is sprayed onto the cable through the marking nozzle 17 (it should be explained that the marker in the marking box 15 is in liquid form) and because the delivery of the gas is delayed, the marking nozzle 17 will not be set below the detection wheel 8, and the detection head can be tilted so that its detection position is close to the marking nozzle 17, thereby ensuring the accuracy of the marking position.

[0043] Reference Figure 7 , and also includes two groups of drying nozzles 18 fixedly connected to the side of the fixed plate 13 close to the marking nozzle 17, two groups of wind wheels 19 are rotatably connected to the side of the fixed plate 13 close to the marking nozzle 17, and an elastic cylinder 20 is fixedly connected to the side of the fixed plate 13 close to the wind wheel 19, wherein the drying nozzles 18 are centrally symmetrically arranged along the marking nozzle 17, and the side of the elastic cylinder 20 close to the wind wheel 19 is inclined, the drying nozzles 18 are connected to the compression assembly 128 through a pipeline, and the elastic cylinder 20 is connected to the vibration cylinder 117 through a pipeline.

[0044] Part of the gas compressed by the compression assembly 128 will be sprayed toward the marking nozzle 17 through the drying nozzle 18, so as to dry the marked position of the cable. In addition, the drying nozzle 18 is staggered with the marking position to prevent the gas from blowing off the marker. When the gas blows toward the wind wheel 19, on the one hand, it can drive the wind wheel 19 to rotate, and on the other hand, the wind wheel 19 can make the gas blow gently toward the marking position to ensure the stability of the marking position and accelerate the drying efficiency of the marker. At the same time, when the wind wheel 19 rotates, After the structure contacts the elastic cylinder 20, it will compress the elastic cylinder 20 and pass the compressed gas into the vibrating cylinder 117, driving the vibrating cylinder 117 to extend outward. After the structure of the wind wheel 19 is separated from the elastic cylinder 20, the cleaning ring 116 will move to the initial position under the action of the second spring 118, thereby driving the cleaning ring 116 to vibrate in the circular ring 113, reducing the adhesion of dust on the cleaning ring 116, so as to facilitate the collection of dust in the circular ring 113 and improve the accuracy of subsequent cable detection results.

[0045] A cable detection device, when used, refers to the following process:

[0046] Step 1: First, the cable is passed through the positioning wheel 3, the cleaning mechanism 11, the size detection unit and the detection mark unit in sequence. The cable transportation can be achieved by the winding device;

[0047] Since there is friction between the cable and the positioning wheel 3, the cable will drive the positioning wheel 3 to rotate during the winding process, which can reduce the wear of the cable while ensuring the stability of the cable position during the winding process.

[0048] Step 2: During the transportation of the cable, the positioning wheel 3 is driven to rotate, thereby driving the driving mechanism 12 to rotate, and the cleaning mechanism 11 can be driven to perform rotational cleaning along the surface of the cable;

[0049] By rotating cleaning, the cleaning effect of dust on the cable surface can be improved.

[0050] Step 3: During the cleaning process, the driving mechanism 12 compresses the gas and passes it to the cleaning mechanism 11, and during cleaning, the cleaned dust is blown out;

[0051] If the dust after cleaning is not discharged in time, it will not only affect the cleaning effect of the subsequent cables, but also make the dust tightly adhere to the cleaning ring 116, making it difficult to ensure the accuracy of the subsequent cable detection results.

[0052] Step 4: During the transportation of the cable, the size detection unit can detect the size of the cable in real time, and when the size is abnormal, it drives the detection marking unit to mark the abnormal part;

[0053] Before testing, the distance between the testing wheel 8 and the positioning wheel 3 is adjusted according to the size of the cable. During the testing process, if the size of the cable becomes smaller or larger, the testing wheel 8 will move, thereby compressing or extending the testing cylinder 7 to facilitate marking of abnormal areas.

[0054] Step 5: Use the detection and marking unit to inspect the appearance and insulation of the cable surface and mark the abnormal parts;

[0055] Step 6: When marking the cable, part of the gas compressed by the driving mechanism 12 is blown toward the marked area to dry it, and the cleaning mechanism 11 is driven to vibrate during the drying process, thereby completing the detection of the cable.

[0056] The drying does not blow the gas directly to the marked area, but blows slowly to the marked area after being decelerated by the wind wheel 19, so as to avoid the situation where the gas blows away the marked object.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
