Description

Technical Field

[0001] The present application relates to the field of cable insulation monitoring, and in particular to a pipeline corridor cable insulation monitoring system. Background Art

[0002] At present, the insulation of the pipeline corridor cables needs to be monitored for a period of time before they are put into use. If the monitoring results prove that there is no leakage in the cables, then the cables can be put into use.

[0003] In the related art, a Chinese patent with application number CN202321567154.X proposes that multiple conductive spring pins are in contact with the outer surface of the cable at the same time. If the outer layer of the cable is broken, the conductive spring pins will be connected, and the insulation will be unqualified. Otherwise, the insulation will be qualified, so that the result of whether the insulation is qualified can be known;

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0005] If there are a lot of dust and stains on the outer surface of the cable, the dust and stains may adhere to the broken parts of the cable, so that the dust and stains will insulate the cable and affect the monitoring results. Summary of the invention

[0006] In order to improve the problem that too much dirt on the outer layer of the cable affects the insulation monitoring results, the present application provides a pipeline corridor cable insulation monitoring system.

[0007] The present application provides a pipeline cable insulation monitoring system that adopts the following technical solutions:

[0008] A cable insulation monitoring system for a pipe corridor includes: a monitoring device body, forming a monitoring chamber for accommodating a cable to be monitored; a first driving member, used to allow the cable to be monitored to pass through the monitoring chamber; an insulation monitoring member, used to monitor the insulation of the cable to be monitored located in the monitoring chamber; a flexible member, arranged in the monitoring chamber, used to form a cleaning surface capable of cleaning the cable to be monitored; a second driving member, used to flexibly deform the flexible member to form a contact groove capable of abutting against a portion of the cable to be monitored and to move the flexible member in a direction perpendicular to the axis of the cable to be monitored; wherein the surface where the contact groove abuts against the cable to be monitored is a cleaning surface.

[0009] By adopting the above technical solution, the dust on the surface of the monitored cable is cleaned before monitoring the monitored cable, thereby preventing the dust and stains on the surface of the monitored cable from affecting the accuracy of insulation monitoring. In addition, the first driving member allows the monitored cable to pass through the monitoring chamber, so the insulation of the entire length of the monitored cable can be quickly monitored, increasing the speed of insulation monitoring. By using the flexible member to flexibly deform and form a contact groove, a larger area of ​​contact with the outer surface of the monitored cable can be achieved, so that when the size of the monitored cable changes, the flexible member can also flexibly deform to make the contact groove contact with the outer surface of the monitored cable, thereby increasing the contact area with the monitored cable, increasing the efficiency of cleaning the dust and stains on the outer surface of the monitored cable, and increasing the adaptability to the monitored cable, so that the insulation of cables of various sizes can be monitored.

[0010] Optionally, the insulation monitoring component is used to form a monitoring area on the cable to be monitored; the monitoring device further includes: a humidifying component; the humidifying component directly or indirectly humidifies the monitoring area.

[0011] By adopting the above technical solution, the outer surface of the monitored cable is first humidified, so that the conductivity of the outer surface of the monitored cable can be increased, so that when there is a problem with the insulation of the monitored cable, it can be more accurately monitored.

[0012] Optionally, the humidifying member includes a water tank and a pressure roller; the flexible member is wound around the pressure roller so that the flexible member is partially immersed below the liquid level of the water tank; the flexible member is water-absorbent, and after the flexible member is moistened by the water tank, the contact groove formed by the flexible member can humidify the monitoring area of ​​the cable.

[0013] By adopting the above technical scheme, the flexible part is first humidified, and then the flexible part humidifies the monitored cable. The monitored cable can be cleaned by the wet flexible part, so the dust and stains on the outer surface of the monitored cable can be humidified, and the force of the dust and stains adhering to the outer surface of the monitored cable is reduced so that the dust and stains can be easily cleaned. At the same time, humidification during cleaning is achieved. The humidification method is simple to implement and the cost is low. The contact groove formed by the flexible part contacts the outer surface of the monitored cable, so that the flexible part can not only increase the cleaning area of ​​the outer surface of the monitored cable but also increase the humidification area of ​​the outer surface of the monitored cable. Through this contact humidification method, not only the humidification speed but also the humidification efficiency is improved, so that the conductivity of the outer surface of the monitored cable is better, and it is easier to monitor the insulation problem of the monitored cable.

[0014] Optionally, a plurality of through holes and a plurality of protrusions protruding relative to the cleaning surface are formed on the flexible member; the plurality of through holes are distributed obliquely relative to the length direction of the flexible member; and the extension direction of the protrusions is obliquely extended relative to the length direction of the flexible member.

[0015] By adopting the above technical solution, the through hole is set up so that in some cases, after the outer surface of the cable to be monitored is wetted, the viscosity between some fine dust particles on the outer surface of the cable to be monitored and the outer surface to be monitored increases, making it difficult to clean. If the flexible member is cleaned by a compressed wiping method, the fine dust particles will be pressed on the cable to be monitored. Then, the through hole is set up so that in some cases, the edge of the through hole can directly scrape off the fine dust particles on the cable to be monitored, making it easy to clean. The protrusion also works on the same principle and can scrape off the fine dust particles on the cable to be monitored. Among them, the plurality of through holes are distributed obliquely relative to the length direction of the flexible member; the extension direction of the protrusion is arranged obliquely relative to the length direction of the flexible member, so as to further increase the contact area when scraping the cable to be monitored by an inclined manner, thereby increasing the effect of scraping off fine dust particles.

[0016] Optionally, the second driving member includes a driving roller, a rotating driving component, two groups of fixed guide rollers, two groups of movable guide rollers and a displacement driving component; the flexible member sequentially bypasses a plurality of the fixed guide rollers and a plurality of the movable guide rollers; the plurality of the movable guide rollers are located at a position close to the cable to be monitored relative to the plurality of the fixed guide rollers, and the plurality of the fixed guide rollers are located at a position away from the cable to be monitored relative to the plurality of the movable guide rollers; the displacement driving component is used to drive the two groups of the movable guide rollers to move close to the cable to be monitored, so that the two flexible members contact the cable to be monitored and form a contact groove; the rotating driving component transports the flexible member between the plurality of the fixed guide rollers and the plurality of the movable guide rollers through the driving roller.

[0017] By adopting the above technical solution, the displacement driving member drives the two groups of movable guide rollers to approach each other, so that the flexible member can contact the cable to be monitored to form a contact groove. Among them, the distance that the displacement driving member drives the two groups of movable guide rollers to approach each other can make the flexible member form contact grooves of different sizes so that the contact grooves and the cable to be monitored have different contact areas. The cleaning method can be selected according to the needs. The larger the contact area between the contact groove and the cable to be monitored, the faster the flexible member is damaged. Therefore, different cleaning methods can be selected in some cases to optionally increase the service life of the flexible member.

[0018] Optionally, the flexible part is a flexible cloth that can form a flexible surface or a flexible wire that can form a flexible surface by splicing multiple wires; when the flexible part is a flexible cloth, the flexible part is a single-layer cloth structure woven from elastic wear-resistant fiber yarns; when the flexible part is a flexible wire, the flexible part is an elastic wear-resistant fiber yarn.

[0019] Optionally, the second driving member also includes: a plurality of stretching guide rollers and a stretching driving member; two of the stretching guide rollers are pressed against the flexible member on both sides of the flexible member by clamping; the two stretching guide rollers used to press against the flexible member on both sides of the flexible member are a group; the plurality of stretching guide rollers form at least two groups; a stretching area is formed between the two groups of stretching guide rollers; and the stretching driving member is used to stretch the flexible member located in the stretching area.

[0020] By adopting the above technical solution, the flexible part is stretched, that is, the flexible part undergoes elastic deformation, and when the flexible part is a single-layer cloth structure woven from elastic wear-resistant fiber yarns, the flexible part is stretched, which will cause multiple small holes or gaps to be formed on the flexible part. Then, the flexible part can be swung or vibrated by external interference, so that some fine particles of dust adhered to the flexible part after the monitoring cable is cleaned can be separated from the flexible part itself through the small holes or gaps, thereby achieving a self-cleaning effect on the flexible part, thereby ensuring the cleaning effect of the flexible part on the monitoring cable.

[0021] Optionally, the flexible member located in the stretching area is placed in the water tank, and the stretching area is located below the liquid level of the water tank.

[0022] By adopting the above technical solution, the position where the flexible part is stretched is in the water tank and is still below the liquid level of the water tank. Then, some fine particles of dust adhering to the flexible part will be separated from the flexible part under the buoyancy of the water, and the fine dust particles will directly reach the water and will not float in the air. This not only realizes the self-cleaning of the flexible part, but also realizes the humidification of the flexible part and the treatment of dust, preventing the dust from floating to other positions and adhering to the flexible part again, and finally improves the cleaning effect of the monitored cable.

[0023] Optionally, the monitoring device also includes: a third driving member, which is used to make the water tank and the flexible member move relative to each other when the flexible member located in the stretching area is stretched; the relative movement of the water tank and the flexible member can make the dust and impurities in the flexible member be separated from the flexible member through reciprocating flushing of water in the water tank.

[0024] By adopting the above-mentioned technical solution, the relative motion of the flexible part in the water and reciprocating relative to the water tank can be realized, so that the water will flush the flexible part and exert resistance on the flexible part. Therefore, when the flexible part is stretched, the water will flush the small holes or gaps formed by the flexible part, so that the dust and impurities on the flexible part can be cleaned more cleanly, further improving the cleaning effect of the flexible part.

[0025] Optionally, the humidifier also includes a brine box for accommodating brine, a receiving box and a pump body component; a groove for allowing the monitored cable to pass through is formed in the brine box; the receiving box is located below the brine box; the liquid level of the brine in the brine box is above the cable to be monitored, and the brine in the brine box overflows into the receiving box through the groove; the pump body component adds the brine in the receiving box to the brine box; the speed at which the brine in the receiving box is added to the brine box is greater than the speed at which the brine box overflows into the receiving box through the groove; the insulation monitoring component is partially located below the liquid level of the brine box.

[0026] By adopting the above technical solution, the cable to be monitored will be immersed in salt water all the time. Then, when there is a problem with the insulation of the cable to be monitored, the insulation monitoring device directly monitors the salt water to determine whether the insulation of the cable to be monitored is good, thereby making monitoring more convenient.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. Before monitoring the cable, clean the dust on the surface of the cable to be monitored, so as to avoid the dust stains on the surface of the cable to be monitored affecting the accuracy of insulation monitoring;

[0029] 2. By using the flexible member to flexibly deform and form a contact groove, a larger area can be contacted with the outer surface of the cable to be monitored. Therefore, when the size of the cable to be monitored changes, the flexible member can also flexibly deform to make the contact groove contact with the outer surface of the cable to be monitored. The insulation of cables of various sizes to be monitored can be monitored and the cleaning effect can be improved.

[0030] 3. By humidifying the outer layer of the cable through the humidifier, the outer layer of the cable can be made more conductive. When a cable breaks and leaks electricity, the probability of being detected is greatly increased, and the result can be better monitored immediately when the leakage occurs.

[0031] 4. By humidifying the flexible part, the cable is humidified when the flexible part contacts the cable, which not only increases the effect of cleaning stains on the cable, but also increases the comprehensive coverage and uniformity of the cable humidification, thereby further improving the investigation of the cable leakage position, so as to more accurately monitor the insulation of the cable;

[0032] 5. The arrangement of multiple through holes and protrusions on the flexible member improves the cleaning effect of the flexible member on the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] The following is combined with Figure 1-19 This application is described in further detail.

[0063] An embodiment of the present application discloses a pipeline corridor cable insulation monitoring system.

[0064] Example 1

[0065] Reference Figure 1-6 ,

[0066] A pipeline corridor cable insulation monitoring system comprises a monitoring device body 1, a first driving member 2, an insulation monitoring member 3, a flexible member 4 and a second driving member 5.

[0067] The monitoring device body 1 forms a monitoring chamber 11 for accommodating the cable to be monitored. The monitoring device body 1 is a shell with a movable carrier 12 at the bottom. The movable carrier 12 is preferably a roller in this embodiment, so that the monitoring device body 1 can be easily moved on the ground.

[0068] The first driving member 2 is used to make the monitored cable pass through the monitoring chamber 11. In this embodiment, the first driving member 2 includes multiple motors 21 and multiple driving wheels 22. The driving wheels 22 are in contact with the monitored cables. The multiple motors 21 drive the monitored cables to move through the multiple driving wheels 22, thereby enabling the monitored cables to move through the monitoring chamber 11. In this embodiment, a rubber sleeve is provided on the outside of the driving wheel 22. The selection of rubber sleeves of different thicknesses enables the driving wheel 22 to contact the monitored cables of different diameters and drive the monitored cables to move through the monitoring chamber 11.

[0069] The insulation monitoring component 3 is used to monitor the insulation of the cable to be monitored in the monitoring chamber 11. In this embodiment, the insulation monitoring component 3 is a multimeter. The two monitoring pens 31 of the multimeter are in contact with the outer surface of the cable to be monitored. Then the multimeter adjusts the voltage to obtain the change in the reading of the multimeter at different positions of the cable, so as to judge the leakage of the cable to be monitored through the multimeter, so that the leakage position can be accurately obtained to facilitate the maintenance and reuse of the cable to be monitored. In other embodiments, the insulation monitoring component 3 can also use an electric pen or an ammeter. The insulation monitoring component 3 is installed on the inner wall surface of the monitoring chamber 11.

[0070] The flexible member 4 is arranged in the monitoring chamber 11 to form a cleaning surface for cleaning the cables to be monitored. In this embodiment, the flexible member 4 is a flexible cloth.

[0071] The second driving member 5 is used to make the flexible member 4 deform flexibly to form a contact groove 41 that can be pressed against part of the cable to be monitored and to make the flexible member 4 move in a direction perpendicular to the axis of the cable to be monitored, wherein the surface of the contact groove 41 pressed against the cable to be monitored is a clean surface. In this embodiment, the second driving member 5 is a belt conveyor, and the flexible member 4 is the belt of the belt conveyor. By making the belt conveyor close to the cable to be monitored, the flexible member 4 can be pressed against the cable to be monitored, and because the two ends of the belt conveyor are located at the upper and lower ends of the cable to be monitored, the flexible member 4 can be flexibly deformed, and the flexible member 4 will be tightly attached to the cable to be monitored, so that the flexible member 4 forms a contact groove 41. Among them, the size of the belt conveyor is small, similar to the cable to be monitored, so that one of the two ends of the belt conveyor is located at the upper end of the cable to be monitored and close to the upper end of the cable to be monitored, and the other end is located at the lower end of the cable to be monitored and close to the lower end of the cable to be monitored.

[0072] By adopting the above technical solution, before monitoring the cable to be monitored, the dust on the surface of the cable to be monitored is cleaned, so as to avoid the dust and stains on the surface of the cable to be monitored affecting the accuracy of insulation monitoring. In addition, the first driving member 2 allows the cable to be monitored to pass through the monitoring chamber 11, so the insulation of the entire length of the cable to be monitored can be quickly monitored, which increases the speed of insulation monitoring. The flexible member 4 is used to flexibly deform and form a contact groove 41, so that a larger area can be contacted with the outer surface of the cable to be monitored, so that when the size of the cable to be monitored changes, the flexible member 4 can also be flexibly deformed to make the contact groove 41 contact with the outer surface of the cable to be monitored, thereby increasing the contact area with the cable to be monitored, increasing the efficiency of cleaning the dust and stains on the outer surface of the cable to be monitored, and increasing the adaptability to the cable to be monitored, so that the insulation of cables of various sizes to be monitored can be monitored.

[0073] Specifically, the insulation monitoring component 3 is used to form a monitoring area on the cable to be monitored; the monitoring device further comprises: a humidifying component 6; the humidifying component 6 directly or indirectly humidifies the monitoring area. In this embodiment, the humidifying component 6 preferably directly humidifies the monitoring area.

[0074] The humidifying component 6 also includes a brine tank 64 body 61 for containing brine, a receiving box 62 and a pump body component 63. Among them, the pump body component 63 is a water pump and corresponding pipelines. A groove 611 for the cable to be monitored to pass through is formed in the brine tank 64 body 61, and the receiving box 62 is located below the brine tank 64 body 61. The liquid level of the brine in the brine tank 64 body 61 is above the cable to be monitored, and the brine in the brine tank 64 body 61 overflows into the receiving box 62 through the groove 611; the pump body component 63 adds the brine in the receiving box 62 to the brine tank 64 body 61; the speed at which the brine in the receiving box 62 is added to the brine tank 64 body 61 is greater than the speed at which the brine tank 64 body 61 overflows into the receiving box 62 through the groove 611; the insulation monitoring component 3 is partially located below the liquid level of the brine tank 64 body 61.

[0075] Specifically, the width of the groove 611 can accommodate the cable to be monitored, so by limiting the width of the groove 611, it can be achieved that the speed at which the brine in the receiving box 62 is added to the brine tank 64 body 61 is greater than the speed at which the brine tank 64 body 61 overflows into the receiving box 62 through the groove 611. The area of ​​the receiving box 62 is larger than the area of ​​the brine tank 64 body 61, so that the brine overflowing from the brine tank 64 body 61 along the groove 611 can flow into the receiving box 62. The groove 611 is a blind groove opened downward from the uppermost end of the brine tank 64 body 61. The two monitoring pens 31 of the multimeter are both placed below the liquid level of the brine tank 64 body 61.

[0076] By adopting the above technical solution, the cable to be monitored will be immersed in salt water all the time. Then, when there is a problem with the insulation of the cable to be monitored, the insulation monitoring component 3 directly monitors the salt water to determine whether the insulation of the cable to be monitored is good, thereby making monitoring more convenient. In addition, the contact between the salt water and the cable to be monitored also has the effect of cleaning the cable to be monitored to a certain extent.

[0077] Example 2

[0078] The difference from the first embodiment is that the humidifying element 6 indirectly humidifies the monitoring area.

[0079] The humidifying member 6 includes a water tank 64 and a pressure roller. The pressure roller is arranged below the liquid level of the water tank 64, and the pressure roller is rotatably connected to the water tank 64. The flexible member 4 is wound around the pressure roller so that a part of the flexible member 4 is immersed below the liquid level of the water tank 64. The flexible member 4 is water-absorbent, and after the flexible member 4 is moistened by the water tank 64, the contact groove 41 formed by the flexible member 4 can humidify the monitoring area of ​​the cable. In this embodiment, the water tank 64 is located below the cable to be monitored, and in this embodiment, the pressure roller is a conveying roller of a belt conveyor. The flexible part 4 is humidified first, and then the flexible part 4 humidifies the monitored cable. The monitored cable can be cleaned by the wet flexible part 4, so the dust and stains on the outer surface of the monitored cable can be humidified, and the force of the dust and stains adhering to the outer surface of the monitored cable is reduced, so that the dust and stains can be easily cleaned. At the same time, humidification during cleaning is achieved. The humidification method is simple to implement and the cost is low. The contact groove 41 formed by the flexible part 4 is in contact with the outer surface of the monitored cable, so that the flexible part 4 can not only increase the cleaning area of ​​the outer surface of the monitored cable but also increase the humidification area of ​​the outer surface of the monitored cable. Through this contact humidification method, not only the humidification speed but also the humidification efficiency is improved, so that the conductivity of the outer surface of the monitored cable is better, and it is easier to monitor the insulation problem of the monitored cable.

[0080] The water in the water tank 64 is ordinary water or ionized water.

[0081] Example 3

[0082] The difference from Example 2 is:

[0083] The flexible member 4 is a flexible cloth that can form a flexible surface or a flexible line that can form a flexible surface by splicing multiple lines. When the flexible member 4 is a flexible cloth, the flexible member 4 is a single-layer cloth structure woven from elastic wear-resistant fiber yarns. When the flexible member 4 is a flexible line, the flexible member 4 is an elastic wear-resistant fiber yarn. In this embodiment, the flexible member 4 is preferably a flexible cloth. The elastic wear-resistant fiber yarn is preferably a polyester fiber yarn.

[0084] Reference Figure 7-9The second driving member 5 includes a mounting shell 51, a driving roller 52, a rotation driving member 53, two groups of fixed guide rollers 54, two groups of mobile guide rollers 55 and a displacement driving member 56. The flexible member 4 passes through the plurality of fixed guide rollers 54 and the plurality of mobile guide rollers 55 in sequence. The plurality of mobile guide rollers 55 are located at positions close to the cables to be monitored relative to the plurality of fixed guide rollers 54, and the plurality of fixed guide rollers 54 are located at positions far away from the cables to be monitored relative to the plurality of mobile guide rollers 55. The driving roller 52, the fixed guide rollers 54 and the mobile guide rollers 55 are all rotatably mounted on the mounting shell 51. The displacement driving member 56 is used to drive the two groups of mobile guide rollers 55 to move close to the cables to be monitored, so that the two flexible members 4 contact the cables to be monitored and form contact grooves 41. The rotation driving member 53 transports the flexible member 4 between the plurality of fixed guide rollers 54 and the plurality of mobile guide rollers 55 through the driving roller 52. In this embodiment, the displacement driving member 56 is one of a cylinder, a hydraulic cylinder and an electric push rod; the rotation driving member 53 is a motor 21. Two driving rollers 52 are provided, and the two driving tubes clamp the flexible member 4. The rotating driving member 53 drives the driving roller 52 to rotate, so as to realize the conveyance of the flexible member 4. The displacement driving member 56 drives the two sets of movable guide rollers 55 to approach each other, so that the flexible member 4 can contact with the cable to be monitored, forming a contact groove 41.

[0085] Among them, a slide groove 511 is opened on the installation shell 51, the movable guide roller 55 is rotatably connected to the slide groove 511, the output end of the displacement driving component 56 is rotatably connected to the movable guide roller 55, and the displacement driving component 56 drives the movable guide roller 55 to move in the slide groove 511, so that the movable guide roller 55 can be close to the cable to be monitored.

[0086] One solution for forming the contact groove 41 of the flexible member 4 is:

[0087] Reference Figure 7-8 The second driving member 5 and the flexible member 4 are both provided with two groups, and the two groups of flexible members 4 are symmetrical about the cable to be monitored. When the two flexible members 4 are pressed against the cable to be monitored and form a contact groove 41, a force will be applied to the cable to be monitored. The symmetry of the two flexible members 4 relative to the cable to be monitored can offset the force applied to the cable to be monitored, so that the cable to be monitored maintains a force balance. At this time, the shape of the contact groove 41 is determined by the position of the movable guide roller 55. The arc of contact between the flexible member 4 and the cable to be monitored is less than 180°.

[0088] Another solution for forming the contact groove 41 of the flexible member 4 is:

[0089] Reference Fig. 9, the second driving member 5 and the flexible member 4 are both provided with two groups, one group of flexible members 4 is located on one side of the cable to be monitored, and the other group of flexible members 4 is located on the other side of the cable to be monitored, and the two groups of flexible members 4 repel each other relative to the length direction of the cable to be monitored, so the two groups of flexible members 4 will apply forces to different positions of the cable to be monitored. However, this can ensure that the arc of contact between the flexible member 4 and the cable to be monitored is greater than or equal to 180°.

[0090] Example 4

[0091] Based on Example 3

[0092] Reference Figure 7-18 The second driving member 5 also includes: a plurality of stretching guide rollers 7 and a stretching driving member 8. The two stretching guide rollers 7 are used to press against the flexible member 4 on both sides of the flexible member 4 by clamping, and the two stretching guide rollers 7 used to press against the flexible member 4 on both sides of the flexible member 4 are a group. When the two stretching guide rollers 7 press against the two sides of the flexible member 4, if the stretching guide rollers 7 are away from each other and the stretching guide rollers 7 cannot rotate, the stretching of the flexible member 4 can be achieved. In the present application, the stretching guide rollers 7 can rotate, so the stretching guide rollers 7 can both guide the flexible member 4 and stretch the flexible member 4.

[0093] The plurality of stretching guide rollers 7 form at least two groups, and a stretching area is formed between the two groups of stretching guide rollers 7. The stretching drive member is used to stretch the flexible member 4 located in the stretching area. When the flexible member 4 is stretched, that is, the flexible member 4 undergoes elastic deformation, and the flexible member 4 is a single-layer cloth structure woven from elastic wear-resistant fiber yarns, the flexible member 4 is stretched, which will cause multiple small holes or gaps to be formed on the flexible member 4. Then, the flexible member 4 can be swung or vibrated by external interference, so that some fine particles of dust adhered to the flexible member 4 after the cable to be monitored is separated from the flexible member 4 itself through the small holes or gaps, which has the effect of self-cleaning the flexible member 4, and ensures the cleaning effect of the flexible member 4 on the cable to be monitored.

[0094] A first specific solution for the stretching driving member to stretch the flexible member 4 located in the stretching area is:

[0095] Reference Figure 7-9, 11, a mounting hole is provided on the mounting shell 51, and the stretching guide roller 7 is rotatably connected to the mounting hole. The stretching driving component 8 includes a first rotating motor 81, a second rotating motor 82 and a mounting frame, the mounting frame is used to install the first rotating motor 81 and the second rotating motor 82, and the mounting frame is fixed to the mounting shell 51. The output end of the first rotating motor 81 is connected to one of the stretching guide rollers 7, and the output end of the second rotating motor 82 is connected to the other stretching guide roller 7. The first rotating motor 81 and the second rotating motor 82 make the rotation speeds of the two stretching guide rollers 7 different. Specifically, along the conveying direction of the flexible member 4, the second rotating motor 82 is located behind the first rotating motor 81, so the first rotating motor 81 drives the stretching guide roller 7 to rotate faster than the second rotating motor 82, so that the flexible member 4 can be stretched.

[0096] A second specific solution for the stretching driving member to stretch the flexible member 4 located in the stretching area is:

[0097] Reference Figure 12-13 , a guide groove is provided on the mounting shell 51, and the stretching guide roller 7 is rotatably connected to the guide groove. The stretching driving member 8 includes a third rotary motor 83, a fourth rotary motor 84, a first electric push rod 85 and a second electric push rod 86. The output end of the third rotary motor 83 is connected to one of the stretching guide rollers 7, the output end of the fourth rotary motor 84 is connected to the other stretching guide roller 7, the output end of the first electric push rod 85 is connected to the third rotary motor 83, and the output end of the second electric push rod 86 is connected to the fourth rotary motor 84. The first electric push rod 85 and the second electric push rod 86 are both mounted on the mounting shell 51. The first electric push rod 85 and the second electric push rod 86 drive the third rotary motor 83 and the fourth rotary motor 84 to move away from each other, so that the two groups of stretching guide rollers 7 can move away from each other and the flexible member 4 can be stretched. The third rotary motor 83 and the fourth rotary motor 84 are used to make the rotation speed of the stretching guide roller 7 the same as the rotation speed of the driving roller 52, or to make the stretching guide roller 7 stationary.

[0098] A third specific solution for the stretching driving member to stretch the flexible member 4 located in the stretching area is:

[0099] Reference Figure 14-18, a mounting hole is provided on the mounting shell 51, and the stretching guide roller 7 is rotatably connected to the mounting hole. The stretching driving member 8 includes a fifth rotary motor 87, a sixth rotary motor 88, a third electric push rod 89 and a pressing portion 80. The pressing portion 80 is connected to the output end of the third electric push rod 89, the output end of the fifth rotary motor 87 is connected to one of the stretching guide rollers 7, and the output end of the sixth rotary motor 88 is connected to the other stretching guide roller 7. The fifth rotary motor 87 and the sixth rotary motor 88 are both fixed to the mounting shell 51, the third electric push rod 89 is fixed to the mounting shell 51, and the third electric push rod 89 drives the pressing portion 80 to move downward, and the pressing portion 80 will press on the flexible member 4 between the two groups of stretching guide rollers 7, and the flexible member 4 is stretched downward, so that the flexible member 4 is stretched and deformed.

[0100] In this solution, the pressing part 80 is a block, and a spherical surface 801 is formed on the pressing part 80, and the spherical surface 801 is used to contact the flexible part 4. When the spherical surface 801 is pressed on the flexible part 4, the flexible part 4 can be stretched along the conveying direction of the flexible part 4 under the action of the pressure of the spherical surface 801, and can also be stretched perpendicular to the conveying direction under the action of the special shape of the spherical surface 801, so that the flexible part 4 can be stretched in two directions, and the small holes or gaps on the flexible part 4 can be better stretched and formed. Among them, when the flexible part 4 is a cloth body, the longitudinal and transverse directions of the weaving of the elastic wear-resistant fiber yarn match the conveying direction of the flexible cloth and the direction perpendicular to the conveying direction; when the flexible part 4 is a plurality of flexible wires, the flexible wires can also be subjected to the force of separation from each other, so that the flexible part 4 can form a gap. In addition, a plurality of perforations are formed on the pressing part 80, and the perforations are used to allow water to flow through the pressing part 80 without being blocked by the pressing part 80, so that the water can pass through the flexible part 4 more smoothly.

[0101] Reference Figure 17-18 In some embodiments, the flexible member 4 located in the stretching area is placed in the water tank 64, and the stretching area is located below the liquid level of the water tank 64. The position where the flexible member 4 is stretched is in the water tank 64 and is still below the liquid level of the water tank 64, so some fine dust particles adhering to the flexible member 4 will be separated from the flexible member 4 under the buoyancy of the water, and the fine dust particles will directly reach the water, so as not to float in the air, thereby not only realizing the self-cleaning of the flexible member 4, but also realizing the humidification of the flexible member 4 and the treatment of dust, preventing the dust from floating to other positions and adhering to the flexible member 4 again, and finally improving the cleaning effect of the cable to be monitored.

[0102] In multiple schemes of this embodiment, the first rotary motor 81, the second rotary motor 82, the third rotary motor 83, the fourth rotary motor 84, the fifth rotary motor 87 and the sixth rotary motor 88 are connected to the stretching guide roller 7 by direct connection or indirect connection. When the connection mode is direct connection, the connection is made through a coupling. When the connection mode is indirect connection, the connection is made by flexible transmission, which refers to chain transmission or belt transmission. In some cases, the stretching guide roller 7 is located in the water tank 64, and the motor 21 is generally difficult to work underwater. Even if the insulation of the motor 21 is qualified and can work underwater, it also requires a high cost. Therefore, the stretching guide roller 7 is located below the liquid level of the water tank 64 by flexible transmission, while the first rotary motor 81, the second rotary motor 82, the third rotary motor 83, the fourth rotary motor 84, the fifth rotary motor 87 and the sixth rotary motor 88 are all located above the liquid level of the water tank 64.

[0103] Reference Figure 17-18 In some embodiments, the monitoring device further comprises: a third driving member 9, wherein the third driving member 9 is used to make the water tank 64 and the flexible member 4 move relative to each other when the flexible member 4 located in the stretching area is stretched. The relative movement of the water tank 64 and the flexible member 4 enables dust and impurities in the flexible member 4 to be separated from the flexible member 4 by reciprocating flushing of the water in the water tank 64.

[0104] A first specific solution for the third driving member 9 is:

[0105] The third driving member 9 is a fourth electric push rod, which is installed on the monitoring device body 1 and is used to drive the mounting shell 51 to move up and down. The water tank 64 is fixed to the monitoring device body 1 , so that the flexible member 4 moves relative to the water tank 64 .

[0106] Reference Fig.17 , the second specific solution about the third driving member 9 is:

[0107] The third driving member 9 is the fifth electric push rod, and the third driving member 9 is fixedly mounted on the mounting shell 51. The output end of the third driving member 9 is connected to the water tank 64. A plurality of third driving members 9 are provided, and the plurality of third driving members 9 are used to drive the water tank 64 to move up and down. The mounting shell 51 is fixed to the monitoring device body 1, thereby realizing the movement of the flexible member 4 relative to the water tank 64.

[0108] When the flexible member 4 moves relative to the water tank 64, the water will flush the flexible member 4 and apply resistance to the flexible member 4. Therefore, when the flexible member 4 is stretched, the water will flush the small holes or gaps formed by the flexible member 4, so that the dust and impurities on the flexible member 4 can be cleaned more cleanly.

[0109] Reference Fig.18 , the third specific solution about the third driving member 9 is:

[0110] The third driving member 9 is a water pump body 91 and a tube body 92; the water pump body 91 and the tube body 92 pump the water in the water tank 64 outward and discharge it downward above the flexible member 4, thereby making the water in the water tank 64 flow. Although the water tank 64 is stationary relative to the flexible member 4 at this time, it can also play a role in flushing the flexible member 4.

[0111] Example 5

[0112] For further explanation, this embodiment is extended as follows based on Embodiment 4:

[0113] Reference Fig.19 The flexible member 4 is formed with a plurality of through holes 42 and a plurality of protrusions 43 protruding relative to the cleaning surface; the plurality of through holes 42 are distributed obliquely relative to the length direction of the flexible member 4; the protrusions 43 extend obliquely relative to the length direction of the flexible member 4. The protrusions 43 are sewn cloth bodies.

[0114] The through holes 42 are provided so that in some cases, after the outer surface of the monitored cable is wetted, the viscosity between some fine dust particles on the outer surface of the monitored cable and the monitored outer surface increases, making it difficult to clean. The protrusion 43 also works on the same principle, and can scrape off the fine dust particles on the monitored cable. Among them, the plurality of through holes 42 are distributed obliquely relative to the length direction of the flexible member 4; the protrusion 43 is extended obliquely relative to the length direction of the flexible member 4, and the contact area when scraping the monitored cable is further increased by an inclined manner, thereby increasing the effect of scraping off fine dust particles.

[0115] The optimal implementation principle of a cable insulation monitoring system for a pipe gallery in multiple embodiments of the present application is:

[0116] Insert the cable to be monitored into the monitoring chamber 11. The first driving member 2 drives the cable to be monitored to move through the monitoring chamber 11. The cable to be monitored is first cleaned and humidified by the flexible member 4, and then reaches the insulation monitoring member 3 for insulation monitoring.

[0117] The process of cleaning and humidifying the cable to be monitored by the flexible part 4 is as follows:

[0118] When the cable to be monitored reaches the position of the flexible member 4, the displacement driving member 56 drives the movable guide roller 55 to move close to the flexible cable to be monitored, and the flexible member 4 contacts the cable to be monitored and forms a contact groove 41; the rotation driving member 53 drives the driving roller 52 to rotate, and the driving roller 52 causes the flexible member 4 to transmit on the driving roller 52, the movable guide roller 55, the fixed guide roller 54 and the stretching guide roller 7, so that the flexible member 4 is in a moving state;

[0119] The flexible member 4 will pass through the water tank 64 during its movement, and the flexible member 4 will be located below the liquid level of the water tank 64 under the action of the pressure roller; the fifth rotary motor 87 and the sixth rotary motor 88 make the rotation speed of the stretching guide roller 7 match the rotation speed of the driving roller 52, so that the flexible member 4 in the stretching area will be normally transmitted, and after the stretching guide roller 7 presses the flexible member 4, as the conveying member moves, the length of the flexible member 4 in the stretching area remains constant, and the third electric push rod 89 drives the pressing part 80 to move downward, and the pressing part 80 presses on the flexible member 4, and the flexible member 4 is pressed downward, so that the flexible member 4 is stretched and deformed, and the stretching of the flexible member 4 will cause the formation of a through hole 42 and a gap on the flexible member 4;

[0120] When the flexible member 4 is in a moving state, the fourth electric push rod drives the water tank 64 to move up and down, so that the water tank 64 moves relative to the flexible member 4 , so that the water in the water tank 64 flushes the flexible member 4 .

[0121] The process of insulation monitoring of the cable to be monitored by the insulation monitoring device 3 is as follows:

[0122] The cable to be monitored after cleaning and humidification moves relative to the monitoring pen 31 of the insulation monitoring component 3 , so that the insulation monitoring component 3 performs insulation monitoring on the cable to be monitored passing through the monitoring pen 31 .

[0123] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
