[0004] During use, cables often need to be inspected after production. The inspection of the cable insulation layer will increase the difficulty due to the wrapping of external materials, resulting in omissions. There is a problem of phase-to-phase breakdown short circuit between conductors due to defects in the insulation layer during subsequent use.

[0031] Embodiment 1

[0032] See also Figure 1-7 As shown, the cable insulation layer defect detection equipment comprises an outer blocking shell 1, an extrusion plate 11 and a telescopic plate 12; the inner side wall of the outer blocking shell 1 is provided with a plurality of groups of extrusion plates 11; the plurality of groups of extrusion plates 11 are in two circles and are staggered; the side walls of the extrusion plates 11 close to the outer blocking shell 1 are fixedly connected with telescopic plates 12; the inner side wall of the outer blocking shell 1 is provided with a pushing wheel 13 between each group of extrusion plates 11; the pushing wheel 13 and the inner side wall of the outer blocking shell 1 are connected by a No. 1 connecting rod 14; the inner side wall of the outer blocking shell 1 is fixedly connected with a pressure weighing sensor 15 at a relative position of each group of extrusion plates 11; the end of the telescopic plate 12 away from the extrusion plate 11 is fixedly connected to the pressure weighing sensor 15; during operation, when the staff conducts insulation layer detection on the cable, the cable can pass through the inner side of the outer blocking shell 1, and the continuous rolling of the pushing wheel 13 drives the cable to continuously Move. At this time, multiple groups of extrusion plates 11 inside the outer blocking shell 1 can contact the side wall of the cable. The extrusion plates 11 will fit tightly to the surface of the cable under the push of the telescopic plates 12. When facing defects in the cable insulation layer, the damage and substandard thickness of the insulation layer at the defective part will cause the telescopic plates 12 to push the extrusion plates 11, so that the extrusion plates 11 and the defective part are squeezed. As the telescopic plates 12 move toward the cable, the pressure of the pressure weighing sensor 15 will change, thereby reminding the staff of the defects in the cable insulation layer. In this step, the extrusion effect of the telescopic plates 12 on the extrusion plates 11 can make the extrusion plates 11 fit to the side wall of the cable. When passing through the defects in the insulation layer, the value changes of the pressure weighing sensor 15 will remind the staff, thereby reducing the occurrence of insulation defects in the cable after leaving the factory, increasing the stability and safety of the cable during use, and reducing the occurrence of short circuits.

[0033] The side wall of the extrusion plate 11 away from the telescopic plate 12 is provided with a plurality of groups of No. 1 chutes 2; an ink cartridge 21 is fixedly connected inside the No. 1 chutes 2; an ink stick 22 is fixedly connected to the side wall of the ink cartridge 21 away from the No. 1 chutes 2; during operation, in the process of the extrusion plate 11 contacting the cable, when facing a defect, the surface of the extrusion plate 11 will fit the defect under the extrusion action of the telescopic plate 12, causing the surface of the extrusion plate 11 to deform, so that the end of part of the ink stick 22 will contact the surface of the cable to mark the defect. This step utilizes the contact between the extrusion plate 11 and the defect of the cable insulation layer to make the ink stick 22 contact the cable to mark the defect, thereby assisting the staff in repairing the defect and reducing the staff's omission of the value of the pressure weighing sensor 15, so that the defect passes smoothly, affecting the subsequent service life of the cable and causing safety hazards.

[0034] The side wall of the No. 1 slide groove 2 is located on the top surface of the ink stick 22 and is fixed with a pair of rubber plates 3; the end of the rubber plate 3 is provided with a No. 2 slide groove 31; a pair of No. 2 slide grooves 31 are respectively slidably connected with a No. 1 magnet 33 and a No. 2 magnet 34; the No. 1 magnet 33 and the No. 2 magnet 34 are magnetically attracted to each other; the No. 1 magnet 33, the No. 2 magnet 34 and the No. 2 slide groove 31 are connected by an elastic band 32; when working, in the process of the extrusion plate 11 performing contact detection on the cable, in the position where the cable insulation layer is intact, the rubber plate 3 installed on the side wall of the No. 1 slide groove 2 can block the top space of the ink stick 22, and then use the magnetic attraction effect of the No. 1 magnet 33 and the No. 2 magnet 34 to drive the elastic band 32 to seal the top space of the ink stick 22, and block the ink stick 22 and the cable. After entering the defect, due to the fit between the extrusion plate 11 and the defect, the surface of the extrusion plate 11 will be deformed, and the No. 1 slide 2 will drive a pair of rubber plates 3 to separate along the two sides of the top of the ink stick 22 under the action of deformation, and the No. 1 magnet 33 and the No. 2 magnet 34 are recovered into the No. 2 slide 31 under the elasticity of the elastic band 32, so that the top of the ink stick 22 and the cable are in contact. This step utilizes the installation of a pair of rubber plates 3 on the side wall of the No. 1 slide 2, which can cooperate with the elastic band 32, the No. 1 magnet 33 and the No. 2 magnet 34 to seal the top of the ink stick 22, reduce the volatilization of the pigment in the ink stick 22, and cause the occurrence of pigment faults and unclear situations when marking the defect later. At the same time, the ink stick 22 and the cable are isolated to reduce the contact between the ink stick 22 and the cable due to external vibration, which causes the mislabeling of the pigment.

[0035] A section of the outer blocking shell 1 is provided with a limit plate 4; a plurality of fixing rings 41 are fixedly connected to the side wall of the limit plate 4; the other end of the fixing ring 41 is connected to the inner side wall of the outer blocking shell 1; a rubber ring 42 is provided at the end of the limit plate 4 away from the fixing ring 41; a section of the rubber ring 42 is inclined; during operation, when the cable passes through the outer blocking shell 1 for detection, the limit plate 4 installed on the end of the outer blocking shell 1 can allow the cable to pass by utilizing the fixing effect of the fixing ring 41. At this time, the rubber ring 42 installed on the end of the limit plate 4 will fit on the side wall of the cable, and the inclined surface of the end of the rubber ring 42 can be used to remove debris adhered to the surface of the cable. In this step, the installation of the limit plate 4 on the end of the outer blocking shell 1 can improve the supporting effect when the cable passes through, increase the stability of the cable inside the outer blocking shell 1, and at the same time, the rubber ring 42 installed on the end of the limit plate 4 can remove debris on the surface of the cable, reduce the debris following the cable into the inner part of the outer blocking shell 1 and affect the detection result, and affect the subsequent detection accuracy.

[0036] The end of the limit plate 4 close to the rubber ring 42 is arranged in a segmented manner, and the ends of the multiple groups of segmented limit plates 4 are fixedly connected to the side walls of the rubber rings 42; the side walls of the segmented limit plate 4 close to the fixing ring 41 are fixedly connected to the No. 1 rotating shaft 5; the No. 1 rotating shaft 5 and the fixing ring 41 are connected by a torsion spring; during operation, when the cable passes through the limit plate 4, the limit plate 4 utilizes its own segmented arrangement, and when facing cables of different specifications, it utilizes the rotatability of the No. 1 rotating shaft 5 to drive the end of the limit plate 4 to open and close. At this time, the rubber ring 42 can also be deformed under its own elasticity, so that the rubber ring 42 follows the opening and closing angle of the limit plate 4. This step utilizes the segmented arrangement of the limit plate 4, and when testing cables of different specifications, the opening angle of the limit plate 4 can be changed by rotating the No. 1 rotating shaft 5, driving the rubber ring 42 to smoothly fit the cable surface, thereby increasing the adaptability of the equipment when testing cables of different specifications.

[0037] The inner side wall of each section of the limit plate 4 is fixedly connected with a No. 2 connecting rod 62; the end of the No. 2 connecting rod 62 is rotatably connected with a No. 2 rotating shaft 61; the No. 2 rotating shaft 61 and the No. 2 connecting rod 62 are connected by a torsion spring; the side wall of the No. 2 connecting rod 62 is fixedly connected with a support plate 6; during operation, when the cable passes through the limit plate 4 for detection, the support plate 6 installed on the inner side wall of the limit plate 4 can contact the side wall of the cable, and contact and squeeze the surface of the cable. At the same time, the torsion spring of the No. 2 rotating shaft 61 will drive the end of the support plate 6 to contact the side wall of the cable. In this step, the support plate 6 installed on the inner side wall of the limit plate 4 can contact and squeeze the side wall of the cable during the movement of the cable, and fix the cable for a second time, thereby improving the support effect on the cable and reducing the occurrence of shaking.

[0038] The top of the support plate 6 is fixedly connected with an anti-skid pad 7; the anti-skid pad 7 is in multiple groups and arranged in a wave shape; during operation, when the support plate 6 and the cable are in contact, the multiple groups of anti-skid pads 7 installed on the top of the support plate 6 can provide additional friction and contact area for the support plate 6. In this step, the multiple groups of anti-skid pads 7 installed on the top of the support plate 6 can provide additional contact area after contacting the cable, thereby increasing the fixing effect of the cable.

[0039] The bottom end of the support plate 6 is fixedly connected to a No. 3 magnet 8; the inner side wall of the limit plate 4 is fixedly connected to a No. 4 magnet 81 at a position corresponding to the No. 3 magnet 8; the No. 3 magnet 8 and the No. 4 magnet 81 are magnetically attracted to each other; during operation, in the process of the support plate 6 and the cable being in contact, the angle of rotation of the support plate 6 varies depending on the size of the cable. At this time, as the support plate 6 rotates, the end of the support plate 6 will be out of contact with the side wall of the limit plate 4. After a section of cable is detected, the support plate 6 will be rubber reset, and the magnetic attraction effect of the No. 3 magnet 8 and the No. 4 magnet 81 will cause a collision between the end of the support plate 6 and the side wall of the limit plate 4 at the moment of contact. This step utilizes the magnetic attraction effect between the No. 3 magnet 8 and the No. 4 magnet 81 to drive the support plate 6 to collide with the side wall of the limit plate 4 when resetting, generating vibration, cleaning the end of the support plate 6 in contact with the cable, increasing the friction force on the subsequent cable, and increasing the fixing effect.

[0040] A section of the outer blocking shell 1 away from the limit plate 4 is equipped with multiple groups of hair dryers 9; the blowing direction of the hair dryer 9 is opposite to the movement of the cable; when working, during the movement of the cable, the hair dryer 9 installed on the end of the outer blocking shell 1 can blow the pigment on the cable to increase the cooling of the pigment. In this step, the multiple groups of hair dryers 9 installed on the end of the outer blocking shell 1 can be used to cool the pigment of the insulation layer defects on the surface of the cable after the cable passes through the outer blocking shell 1, thereby reducing the occurrence of smearing caused by mutual friction of pigments when multiple groups of cables are in contact, which affects the accuracy of the marking.

[0041] A No. 3 slide groove 101 is provided on the inner side wall of the rubber ring 42; during operation, when the side wall of the rubber ring 42 contacts the cable, as the cable moves, the No. 3 slide groove 101 provided on the side wall where the rubber ring 42 contacts the cable can perform secondary cleaning on the cable surface by itself. In this step, the opening of the No. 3 slide groove 101 can be used to scrape the cable multiple times when the rubber ring 42 scrapes and cleans the cable surface, thereby increasing the cleaning effect of the rubber ring 42 on the cable and reducing the influence of debris on the detection result inside the outer blocking shell 1.

[0042] Embodiment 2

[0043] See also Figure 8As shown, compared with Example 1, as another implementation of the present invention, a plurality of positioning plates 111 are fixedly connected to the bottom of the outer barrier shell 1; a drill hole 112 is provided on the top surface of the positioning plate 111; when working, during the process of the outer barrier shell 1 detecting the cable, the plurality of positioning plates 111 installed on the bottom of the outer barrier shell 1 can increase the additional contact area with the ground, and then the drill hole 112 can provide a connection between the screw and the ground. This step utilizes the additional grounding area provided by the positioning plate 111 and the drill hole 112 to increase the stability of the outer barrier shell 1 during operation and reduce the occurrence of shaking.

[0044] Working principle: When the staff is testing the insulation layer of the cable, the cable can pass through the outer blocking shell 1. Under the continuous rolling of the pushing wheel 13, the cable is driven to move continuously. At this time, multiple groups of extrusion plates 11 inside the outer blocking shell 1 can contact the side wall of the cable. The extrusion plates 11 will fit tightly to the surface of the cable under the push of the telescopic plate 12. When facing defects in the insulation layer of the cable, the insulation layer itself is damaged and the thickness does not meet the standard, which will cause the telescopic plate 12 to push the extrusion plate 11, so that the extrusion plate 11 and the defect are squeezed. As the telescopic plate 12 moves toward the cable, the pressure of the pressure weighing sensor 15 will change, thereby reminding the staff of defects in the insulation layer of the cable. In the process of contact between the extrusion plate 11 and the cable, when facing defects When the cable is in a defective position, the surface of the extrusion plate 11 will fit with the defective position under the extrusion of the telescopic plate 12, causing the surface of the extrusion plate 11 to deform, so that the end of part of the ink stick 22 will contact the cable surface, marking the defective position. In the process of the extrusion plate 11 performing contact detection on the cable, at the position where the cable insulation layer is intact, the rubber plate 3 installed on the side wall of the No. 1 slide 2 can block the top space of the ink stick 22, and then use the magnetic attraction effect of the No. 1 magnet 33 and the No. 2 magnet 34 to drive the elastic belt 32 to seal the top space of the ink stick 22, and block the ink stick 22 and the cable. After entering the defective position, due to the fit of the extrusion plate 11 and the defective position, the surface of the extrusion plate 11 will be deformed, and the No. 1 slide 2 will drive the No. 1 slide 2 to deform under the action of the deformation. The rubber plate 3 is separated along both sides of the top of the ink stick 22, and the No. 1 magnet 33 and the No. 2 magnet 34 are recovered into the No. 2 slide groove 31 under the elasticity of the elastic band 32, so that the top of the ink stick 22 is in contact with the cable. In the process of the cable passing through the outer blocking shell 1 for detection, the limit plate 4 installed on the end of the outer blocking shell 1 can allow the cable to pass by utilizing the fixing effect of the fixing ring 41. At this time, the rubber ring 42 installed on the end of the limit plate 4 will fit on the side wall of the cable, and the inclined surface of the end of the rubber ring 42 can be used to remove debris adhering to the surface of the cable. In the process of the cable passing through the limit plate 4, the limit plate 4 can utilize its own segmented setting to drive the end of the limit plate 4 to open and close when facing cables of different specifications by utilizing the rotatability of the No. 1 rotating shaft 5. At this time, the rubber ring 42 can also be deformed under its own elasticity, so that the rubber ring 42 follows the opening and closing angle of the limit plate 4. When the cable passes through the limit plate 4 for detection, the support plate 6 installed on the inner side wall of the limit plate 4 can contact the side wall of the cable to contact and squeeze the surface of the cable. At the same time, the torsion spring of the second rotating shaft 61 will drive the end of the support plate 6 to contact the side wall of the cable. In the process of contact between the support plate 6 and the cable, the multiple groups of anti-slip pads 7 installed on the top of the support plate 6 can provide additional friction and contact area for the support plate 6. In the process of contact between the support plate 6 and the cable, the rotation angle of the support plate 6 is different depending on the size of the cable. At this time, as the support plate 6 rotates, the end of the support plate 6 will be out of contact with the side wall of the limit plate 4.After a section of cable is inspected, the support plate 6 will be reset by rubber. The magnetic attraction between the No. 3 magnet 8 and the No. 4 magnet 81 will cause a collision between the end of the support plate 6 and the side wall of the limit plate 4 at the moment of contact. During the movement of the cable, the blower 9 installed on the end of the outer blocking shell 1 can blow the paint on the cable to increase the cooling of the paint. When the side wall of the rubber ring 42 contacts the cable, as the cable moves, the No. 3 slide groove 101 opened on the side wall where the rubber ring 42 contacts the cable can use itself to clean the cable surface for the second time.
