Description

Technical Field

[0001] The invention belongs to the technical field of cable detection, and in particular relates to an intelligent detection device and a detection method for a special flame-retardant cable. Background Art

[0002] The cable is a rope-like cable made of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering. During the installation and connection process of the cable, if the cable is inspected, the harm caused by inferior cables can be reduced, and surface defects such as bulges, pits, scratches, uneven thickness, and insulation material that is too thin or too thick can be easily found.

[0003] The existing patent application number is CN202311593169.8, which is a detection device and detection method for a special flame-retardant cable. The device includes a first partition and a second partition arranged at intervals in a shell, and the first partition and the second partition divide the interior of the shell into a first chamber, a second chamber and a third chamber in sequence. Four guide booster assemblies for bending the cable in different directions and introducing detection liquid into the damaged part are installed in the first chamber, a cleaning assembly for absorbing moisture on the surface of the cable is installed in the second chamber, and four guide booster assemblies for bending the cable in different directions and introducing hot air into the damaged part are installed in the third chamber. When the guide wheel rotates, the cover plate can be intermittently close to the mounting disk so that the volume of the pressure chamber is intermittently reduced. The present invention is conducive to the rapid entry of the detection liquid into the damaged part of the cable insulation layer, and is conducive to the rapid removal of water in the damaged part of the cable insulation layer.

[0004] The above patent only stretches and amplifies the defects or cracks of the cable to determine whether these defects or cracks will affect the insulation of the cable, but it cannot accurately locate the positions of these defects or cracks. If these defects or cracks can be repaired, it is difficult to repair them by positioning, especially the cracks, which are difficult to observe. At the same time, some bulges in the cable are caused by the deterioration and expansion of the insulation layer, which will not affect the insulation of the cable in a short time, but may gradually spread and become larger with the increase in usage time. The above patent cannot perform positioning judgment. At the same time, if the cable insulation layer is too thick, although it will not reduce the insulation of the cable, it will affect the balance of the wire. If the cable insulation layer is too thin, it will reduce the insulation of the cable. However, the above patent can only determine that the cable insulation is insufficient, but cannot determine what caused it. When tracing the source of the problem, it is impossible to accurately determine the cause of the problem, and it is impossible to perform targeted cable repairs or cable production adjustments.

[0005] Therefore, in view of the above technical problems, it is necessary to provide an intelligent detection device and detection method for special flame-retardant cables.

[0049] like Figure 2As shown, the directions of the input end and the output end of the first reversing wheel 7 are perpendicular, and four stretching wire wheels 5 are rotatably installed in the immersion detection tank 101. The plane where the input end and the output end of the first stretching wire wheel 5 are located is the same plane as the plane where the input end and the output end of the first reversing wheel 7 are located, the directions of the input end and the output end of the first stretching wire wheel 5 are opposite, and the direction of the output end of the first stretching wire wheel 5 and the output end of the first reversing wheel 7 are opposite, the plane where the input end and the output end of the second stretching wire wheel 5 are located is the same plane as the plane where the input end and the output end of the first stretching wire wheel 5 are located, the directions of the input end and the output end of the second stretching wire wheel 5 are opposite, and the direction of the output end of the second stretching wire wheel 5 and the output end of the first stretching wire wheel 5 are opposite, and the plane where the input end and the output end of the third stretching wire wheel 5 are located is the same plane as the first The planes on which the input and output ends of the two stretching wire wheels 5 are located are perpendicular, the directions of the input and output ends of the third stretching wire wheel 5 are opposite, the directions of the output end of the third stretching wire wheel 5 and the output end of the second stretching wire wheel 5 are opposite, the plane on which the input and output ends of the fourth stretching wire wheel 5 are located is the same plane as the plane on which the input and output ends of the third stretching wire wheel 5 are located, the directions of the input and output ends of the fourth stretching wire wheel 5 are opposite, the directions of the output end of the fourth stretching wire wheel 5 and the output end of the third stretching wire wheel 5 are opposite, the plane on which the input and output ends of the second reversing wheel 8 are located is perpendicular to the plane on which the input and output ends of the fourth stretching wire wheel 5 are located, the directions of the input and output ends of the second reversing wheel 8 are perpendicular, and the directions of the output end of the second reversing wheel 8 and the output end of the fourth stretching wire wheel 5 are perpendicular.

[0050] like Figure 3 As shown, a fixed shell 501 is fixedly installed in the immersion detection tank 101, the fixed shell 501 is rotatably connected to the stretching wire wheel 5, and a defoaming brush 502 matching the cable 2 is fixedly installed in the fixed shell 501.

[0051] A vibration motor 10 is fixedly mounted on the fixed base 1 , and the fixed shell 501 is fixedly connected to the driving end of the vibration motor 10 .

[0052] by Figure 2Taking the direction in which the middle cable 2 enters the first stretching wire wheel 5 as an example, the cable 2 is divided into four areas: front, rear, upper and lower. The cable 2 is stretched in the lower area of ​​the first stretching wire wheel 5, so that the depressions and cracks in the lower area are stretched and enlarged due to the stretching deformation of the cable 2. When the cable 2 passes through the second stretching wire wheel 5, the upper area of ​​the original cable 2 is stretched and enlarged, so that the depressions and cracks in the lower area are stretched and enlarged due to the stretching deformation of the cable 2. When the cable 2 passes through the third stretching wire wheel 5, the front area of ​​the original cable 2 is stretched and enlarged, so that the depressions and cracks in the front area are stretched and enlarged due to the stretching deformation of the cable 2. When the cable 2 passes through the fourth stretching wire wheel 5, the rear area of ​​the original cable 2 is stretched and enlarged, so that the depressions and cracks in the rear area are stretched and enlarged due to the stretching deformation of the cable 2, and the detection liquid and the fluorescent agent can enter the stretched and enlarged depressions and cracks.

[0053] At the same time, air will remain in the depressions and cracks. Under the action of water tension, bubbles will remain in these depressions or cracks even if the depressions and cracks are stretched and expanded. Therefore, when the cable 2 passes through the stretching wire wheel 5, it will rotate relative to the fixed shell 501, so that the bubble removal brush 502 brushes the surface of the cable 2 to remove these bubbles, so that the detection liquid and the fluorescent agent can smoothly enter the depressions and cracks, and the vibration motor 10 drives the bubble removal brush 502 to vibrate, further improving the bubble removal effect.

[0054] like Figure 6 and Figure 7 As shown, the bottom end of the first coating box 13 is provided with a first material storage trough 134 and a first material delivery port 135, the first material delivery port 135 is connected with the first material storage trough 134, a first material supply roller 138 is rotatably installed in the first material storage trough 134, and the cylindrical surface of the first material supply roller 138 is against the cylindrical surface of the first coating roller 137;

[0055] The second fluorescent paint is filled into the first storage tank 134 through the first feeding port 135, so that the surface of the first feeding roller 138 is full of the second fluorescent paint, and the liquid level of the second fluorescent paint is lower than the lowest point of the first coating roller 137. When the first gear ring 132 is driven to rotate by the first gear 133, the first coating roller 137 will also rotate, and constantly contact and resist the first feeding roller 138, so that the first coating roller 137 and the first feeding roller 138 not only revolve in the first coating box 13 under the action of mutual friction, but also rotate on their own, so that the cylindrical surface of the first coating roller 137 also absorbs the second fluorescent paint. The second fluorescent paint on the first feeding roller 138 is used to apply a second fluorescent coating to the surface of the cable 2. If the first coating roller 137 is in direct contact with the second fluorescent paint, too much of the second fluorescent paint will remain on the surface of the first coating roller 137, causing overflow, thus affecting subsequent detection. When the first coating roller 137 rotates to the highest point, the second fluorescent paint may drip onto the surface of the cable 2. The coating is transferred by the first feeding roller 138, so that the second fluorescent paint can always remain on the surface of the first coating roller 137, and will not absorb too much of the second fluorescent paint to cause overflow and dripping.

[0056] like Figure 8 and Fig. 9 As shown, the second paint box 14 has a second material storage trough 144 and a second material delivery port 145 at the bottom end. The second material delivery port 145 is connected to the second material storage trough 144. A second material supply roller 148 is rotatably installed in the second material storage trough 144. The cylindrical surface of the second material supply roller 148 abuts against the cylindrical surface of the second paint roller 147.

[0057] The third fluorescent paint is filled into the second storage tank 144 through the second feeding port 145, so that the surface of the second feeding roller 148 is full of the third fluorescent paint, and the liquid level of the third fluorescent paint is lower than the lowest point of the second coating roller 147. When the second gear ring 142 is driven to rotate by the second gear 143, the second coating roller 147 will also rotate, and constantly contact and abut against the second feeding roller 148, so that the second coating roller 147 and the second feeding roller 148 not only revolve in the second coating box 14 under the action of mutual friction, but also rotate on their own, so that the cylindrical surface of the second coating roller 147 also absorbs the third fluorescent paint. The third fluorescent paint on the second feeding roller 148 is used to apply a third fluorescent coating to the surface of the cable 2. If the second coating roller 147 is in direct contact with the third fluorescent paint, too much third fluorescent paint will remain on the surface of the second coating roller 147, causing overflow, thus affecting subsequent inspections. When the second coating roller 147 rotates to the highest point, the third fluorescent paint may drip onto the surface of the cable 2. The coating is transferred by the second feeding roller 148, so that the third fluorescent paint will always remain on the surface of the second coating roller 147, and will not absorb too much third fluorescent paint to cause overflow and dripping.

[0058] like Figure 4 and Figure 5 As shown, an input limit tube 11 and an output limit tube 12 are fixedly installed on the fixed base 1, and a plurality of limit arc plates 17 are slidably installed in the input limit tube 11 and the output limit tube 12. An adjusting bolt 171 is rotatably installed on the limit arc plate 17, and the adjusting bolt 171 is threadedly connected to the input limit tube 11 or the output limit tube 12. A limit slide bar 172 is fixedly installed on the limit arc plate 17, and the limit slide bar 172 is slidably connected to the input limit tube 11 or the output limit tube 12.

[0059] A plurality of balls 173 are rotatably mounted on the limiting arc plate 17 .

[0060] like Figure 1 As shown, the input limit tube 11 is located between the first coating box 13 and the second wire wheel 4, and the output limit tube 12 is located between the second coating box 14 and the fluorescence detector 15. The distance between the limit arc plates 17 is adjusted by rotating the adjusting bolt 171, so as to finely adjust the position height and orientation of the cable 2 passing through the input limit tube 11 and the output limit tube 12, so that when the cable 2 passes through the first coating box 13 and the second coating box 14, the central axis of the cable 2 always overlaps with the central axis of the first gear ring 132, the first rotating ring 136, the second gear ring 142 and the second rotating ring 146. When the first coating roller 137 and the second coating roller 147 apply coating to the cable 2 for the second and third time, no error will be generated due to the offset of the cable 2, thereby affecting subsequent detection.

[0061] The limiting slide bar 172 is used to limit the limiting arc plate 17 to prevent the limiting arc plate 17 from rotating along with the adjusting bolt 171 in the input limiting tube 11 or the output limiting tube 12 when the adjusting bolt 171 is rotated. The ball 173 can reduce the friction between the limiting arc plate 17 and the cable 2. When the cable 2 passes through the input limiting tube 11 and the output limiting tube 12, the ball 173 rolls along with the cable 2 to prevent the limiting arc plate 17 from causing wear on the paint on the surface of the cable 2 due to friction when the cable 2 passes through the input limiting tube 11 or the output limiting tube 12, thereby affecting the subsequent fluorescence detection.

[0062] like Figure 1As shown, a heat dryer 16 is fixedly installed at the input port of the input limit tube 11, the output port of the first paint box 13 and the output port of the second paint box 14. After the cable 2 is coated with the first paint in the fixed base 1, the heat dryer 16 on the input limit tube 11 performs the first drying to prevent the first fluorescent paint from flowing on the surface of the cable 2 due to non-solidification and affecting the subsequent second coating. After the cable 2 is coated with the second paint in the first paint box 13, the heat dryer 16 on the first paint box 13 performs the second drying to prevent the second fluorescent paint from flowing on the surface of the cable 2 due to non-solidification and affecting the subsequent third coating. After the cable 2 is coated with the second paint in the second paint box 14, the heat dryer 16 on the second paint box 14 performs the third drying to prevent the third fluorescent paint from flowing on the surface of the cable 2 due to non-solidification and affecting the fluorescence detection of the fluorescence detector 15.

[0063] like Figure 2 As shown, a dust removal cover 9 is fixedly installed at the front end of the fixed base 1. The position of the dust removal cover 9 matches the position of the first wire wheel 3. The dust removal cover 9 removes dust from the surface of the cable 2 entering the first wire wheel 3 to prevent dust and impurities from being adsorbed and accumulated on the surface of the cable 2, affecting the subsequent current detection and fluorescent coating. The dust removal cover 9 can be a wet sponge ring.

[0064] like Figure 7 As shown, the radius of the circle generated by the rotation of the central axis of the first coating roller 137 in the first coating box 13 is equal to the radius of the cable 2 plus the radius of the first coating roller 137;

[0065] R1-R2=r

[0066] Wherein, r is the radius of the cable 2, R2 is the radius of the first coating roller 137, and R1 is the radius of the circle generated when the central axis of the first coating roller 137 rotates.

[0067] like Fig. 9 As shown, the radius of the circle generated by the rotation of the central axis of the second coating roller 147 in the second coating box 14 is slightly larger than the radius of the cable 2 plus the radius of the second coating roller 147;

[0068] R3-R4>r

[0069] Wherein, r is the radius of the cable 2, R4 is the radius of the second coating roller 147, and R3 is the radius of the circle generated when the central axis of the second coating roller 147 rotates.

[0070] Because R1-R2=r, the first coating roller 137 abuts against the surface of the cable 2. When the cable 2 passes through the first coating box 13, the rotating first coating roller 137 applies a second fluorescent coating to the normal area and the raised area on the surface of the cable 2.

[0071] Because R3-R4>r, the second coating roller 147 will not contact the surface of the cable 2, but the distance between the second coating roller 147 and the surface of the cable 2 is small, and the second coating roller 147 will contact and contact the protrusions on the surface of the cable 2. When the cable 2 passes through the second coating box 14, the rotating second coating roller 147 will not apply fluorescent paint to the normal area of ​​the surface of the cable 2, but will apply the third fluorescent paint to the protrusions on the cable 2;

[0072] Therefore, the first fluorescent paint will remain in the depressions and cracks on the cable 2, the first fluorescent paint in the normal area will be covered by the second fluorescent paint, and the second fluorescent paint in the protrusions will be covered by the third fluorescent paint.

[0073] The present invention inputs the cable 2 through the first wire wheel 3, so that the cable 2 passes through the first wire wheel 3, the first reversing wheel 7, four stretching wire wheels 5, the second reversing wheel 8, the second wire wheel 4, the input limit tube 11, the first paint box 13, the second paint box 14, the output limit tube 12, the fluorescence detector 15 and the third wire wheel 18, and the cable 2 is output from the third wire wheel 18;

[0074] Rotate the adjusting bolts 171 on the input limit tube 11 and the output limit tube 12 to adjust the height of the cable 2 passing through the first coating box 13 and the second coating box 14, so that the central axis of the cable 2 overlaps with the central axes of the first gear ring 132, the first rotating ring 136, the second gear ring 142 and the second rotating ring 146;

[0075] A conductive solution mixed with a first fluorescent solvent is delivered to the immersion detection tank 101 through the infusion tube 102. The conductive solution is a sodium chloride solution. The first fluorescent solvent can be red. The first fluorescent solvent will not affect the conductivity of the conductive solution. A second fluorescent solvent is delivered to the first storage tank 134 through the first delivery port 135. The second fluorescent solvent can be blue. A third fluorescent solvent is delivered to the second delivery port 145 through the second delivery port 145. The third fluorescent solvent can be yellow.

[0076] The first wire wheel 3, the second wire wheel 4 and the third wire wheel 18 are started. When the cable 2 passes through the immersion detection tank 101, it is stretched in four directions by the four stretching wire wheels 5, so that the depressions and cracks on the cable 2 are stretched and expanded, and the conductive solution mixed with the first fluorescent solvent enters the depressions and cracks. At this time, the depressions, cracks, normal areas and protrusions on the cable 2 are all red. The cable 2 is powered on, and the current sensor 6 is used to detect whether the cable 2 is leaking electricity, so as to determine the insulation of the cable 2;

[0077] The cable 2 coated with the first fluorescent solvent is input into the heat drying device 16 on the limiting tube 11 for drying, and then enters the first coating box 13, and is subjected to a second fluorescent coating by the first coating roller 137 rotating in the first coating box 13, so that the normal area and the protrusions on the surface of the cable 2 are coated with the second fluorescent solvent, so that the original red color of the normal area and the protrusions is covered with blue;

[0078] The cable 2 is then dried for the second time by the heat drying device 16 at the first coating box 13, and then enters the second coating box 14, where the second coating roller 147 rotates in the second coating box 14 to perform a third fluorescent coating, so that the protrusions on the cable 2 are coated with the third fluorescent solvent, so that the original blue color of the protrusions is covered with yellow;

[0079] The cable 2 that has been fluorescently coated three times enters the fluorescent detector 15, and the fluorescent detector 15 performs fluorescent detection and judgment on the cable 2. The red area is a concave or crack area, the blue area is a normal area, and the yellow area is a convex area;

[0080] The maintenance personnel repair the cable 2 according to the judgment result of the fluorescence detector 15. If the insulation of the cable 2 cannot meet the use requirements and the depressions or cracks are difficult to repair, the cable 2 is discarded and replaced.

[0081] If cable 2 is leaking electricity, it means that cable 2 is unqualified. Then, it is judged whether cable 2 can be repaired according to the red sunken and cracked areas and the yellow raised areas. If it is difficult to repair, cable 2 is discarded and replaced. If it is repairable, it is repaired.

[0082] If the cable 2 does not leak electricity, the red sunken and cracked areas and the yellow raised areas are judged to determine whether the impact of these areas will expand as the cable 2 is used longer, thereby affecting the insulation and flame retardancy of the cable 2, and then determine whether to repair these areas;

[0083] At the same time, if the insulation layer of part of the cable 2 is too thick, this part of the area will not only contact and abut against the first coating roller 137 but also contact and abut against the second coating roller 147 when passing through the first coating box 13 and the second coating box 14. It will not only be fluorescently painted by the first coating roller 137 for the second time but also be fluorescently painted by the second coating roller 147 for the third time. The whole area will be yellow due to the third fluorescent painting instead of the spotty yellow of the raised area. Therefore, it can be judged that the insulation layer of this area is too thick.

[0084] If the insulation layer of part of the cable 2 is too thin, this part of the area will not come into contact with the first coating roller 137 and the second coating roller 147 when passing through the first coating box 13 and the second coating box 14. Not only will it not be fluorescently coated for the second time by the first coating roller 137, but it will also not be coated for the third time by the second coating roller 147. As a result, the entire area still retains the red color of the first coating, rather than the spotted red color of depressions or cracks, so that it can be judged that the insulation layer of this area is too thin.

[0085] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
