[0003] When laying cables, people often choose to bury them underground. Cables buried underground will be corroded by acids and alkalis in the soil, and the moisture in the soil will further aggravate the corrosion of the cables. Once the cables are severely corroded, their performance will decline, their insulation will fail, and even safety accidents may occur.

[0004] Adding an anti-corrosion protective cover to the outermost layer of the cable is one of the common methods in the prior art to improve the anti-corrosion performance of the cable. However, as the cable is used, the protective cover will inevitably be damaged and needs to be maintained and replaced in time. Therefore, the cable needs to be inspected regularly. However, since the cable is buried underground, if you want to detect whether the protective cover on the cable is damaged, you need to dig out the cable, which is very troublesome.

DETAILED DESCRIPTION

[0027] Three implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0028] The first implementation method:

[0029] Figure 1-3 A high-safety anti-corrosion cable is shown, including a cable body 001, on which a plurality of anti-corrosion protection components are arranged, the anti-corrosion protection components including a pair of end sealing rings 202 sleeved on the cable body 001 and an anti-corrosion outer sheath 201 sleeved on the pair of end sealing rings 202, the pair of end sealing rings 202 are respectively located at the two ends of the anti-corrosion outer sheath 201, and the end sealing rings 202 are sealed and fixedly connected to the anti-corrosion outer sheath 201 and the cable body 001, a detection support tube 203 is embedded in the middle of the end sealing ring 202, a live seal linkage plate 204 connected to the detection support tube 203 in a sliding and sealing manner is arranged in the detection support tube 203, the top of the live seal linkage plate 204 is fixedly connected to an iron block 205 and a push rod 208, and the live seal linkage plate A plurality of wet swelling top plate balls 206 are filled below 204, a plurality of connecting holes 207 evenly distributed in a ring shape are opened on the outer wall of the detection support tube 203, a magnetic isolation plate 209 is arranged above the iron block 205, one end of the magnetic isolation plate 209 is hinged to the inner wall of the detection support tube 203, the top end of the top rod 208 is against the bottom end of the magnetic isolation plate 209, the connecting hole 207 is located on the inner side of the anti-corrosion outer sheath 201 and below the live seal linkage plate 204, the anti-corrosion outer sheath 201 is made of flexible corrosion-resistant material, the detection support tube 203 is made of hard corrosion-resistant material, and the corrosion resistance of the detection support tube 203 is better than that of the anti-corrosion outer sheath 201, the wet swelling top plate ball 206 is made of water-absorbing and swelling material, and the magnetic isolation plate 209 is made of magnetic isolation material.

[0030] When burying the cable, make the detection support tube 203 face vertically upward, and record the position of each detection support tube 203. The anti-corrosion outer sheath 201 in the anti-corrosion protection component can provide an effective protection for the cable body 001 to prevent the cable body 001 from being corroded. When inspecting the cable, if the anti-corrosion outer sheath 201 has been corroded and damaged, the moisture in the soil can penetrate into the inner side of the anti-corrosion outer sheath 201 through the damaged part, and then enter the detection support tube 203 through the connecting hole 207, causing the swelling top plate ball 206 to absorb water and expand. The expansion of the swelling top plate ball 206 will push the live seal linkage plate 204 upward, causing the live seal linkage plate 204 to drive the iron block 205 and the push rod 208 to move upward, and the upward movement of the push rod 208 will push The magnetic isolation plate 209 makes the magnetic isolation plate 209 swing upward. On the contrary, if the anti-corrosion outer sheath 201 is still intact, the live seal linkage plate 204, the iron block 205 and the push rod 208 will not move upward, and the magnetic isolation plate 209 will not swing upward. Therefore, when inspecting the cable, you can take a magnet and place it on the ground directly above the detection support tube 203, and then use a reasonable method to detect the magnetic interaction force exerted on the magnet. If the anti-corrosion outer sheath 201 is still intact, under the magnetic isolation effect of the magnetic isolation plate 209, the magnetic interaction force between the magnet and the iron block 205 will be very small. On the contrary, if the anti-corrosion outer sheath 201 is damaged, since the magnetic isolation plate 209 swings upward under the push of the push rod 208, the magnetic isolation plate 209 will be damaged. The magnetic isolation effect will be significantly reduced, and because the iron block 205 moves upward, the distance between the iron block 205 and the magnet will be significantly shortened, so the magnet will be subjected to a relatively large magnetic interaction force. Therefore, the damage of the anti-corrosion outer sheath 201 can be judged by detecting the magnetic interaction force exerted on the magnet, without digging out the cable, and because the inspection operation is simple and efficient, the inspection cycle can be appropriately shortened according to the situation, that is, the cable can be inspected more frequently, so that the damage of the anti-corrosion outer sheath 201 can be discovered more timely. Therefore, through the setting of the anti-corrosion protection component, the anti-corrosion outer sheath 201 in the anti-corrosion protection component can provide an effective protection for the cable body 001 to prevent the cable body 001 from being corroded, thereby The anti-corrosion performance of the cable is greatly improved, and when inspecting the cable, it is not necessary to dig out the cable to check whether the anti-corrosion outer sheath 201 is damaged. The inspection operation is simple, efficient and accurate, so that relevant technical personnel can more quickly, accurately and timely check whether the anti-corrosion outer sheath 201 is damaged, so that the damaged anti-corrosion outer sheath 201 can be maintained and replaced more timely, thereby further improving the anti-corrosion performance of the cable and effectively extending the service life of the cable; in addition, in order to ensure the accuracy of the inspection, when burying the cable, it is necessary to remove the ferromagnetic substances and other substances that may affect the inspection in the soil around the detection support tube 203 as much as possible. As for how to remove these substances, it is a well-known technology of those skilled in the art and will not be elaborated here;In addition, in order to avoid the accuracy of the inspection being affected by the corrosion and damage of the detection support tube 203, a protective tube can be set on the outside of the detection support tube 203, and the protective tube can cover the detection support tube 203, and the material and thickness of the protective tube are the same as the anti-corrosion outer sheath 201, so as to prevent the detection support tube 203 from being corroded and damaged before the anti-corrosion outer sheath 201, thereby ensuring the accuracy of the inspection; in addition, if the cable is buried deep, a pit of suitable depth can be dug above the detection support tube 203. During the inspection, the magnet is placed in the pit, and it can even be dug deep until the top of the detection support tube 203 is leaked. In this way, the distance between the magnet and the detection support tube 203 can be greatly shortened, thereby improving the accuracy of the inspection. ;

[0031] The second implementation method:

[0032] Figure 4-5 A high-security anti-corrosion cable is shown. Different from the first embodiment, the high-security anti-corrosion cable is also equipped with a magnetic pressure damage detection device, which includes a U-shaped support frame 401, a support box 402 is fixedly installed on the inner side of the support frame 401, a pressure sensor 403 is fixedly installed inside the support box 402, an electromagnet 404 is arranged above the support box 402, a transmission rod 405 is fixedly connected to the bottom end of the electromagnet 404, a display screen 406 is also fixedly installed on the inner side of the support frame 401, the transmission rod 405 passes through the top outer wall of the support box 402 and extends to abut against the pressure sensor 403, and the transmission rod 405 is slidably connected to the outer wall of the support box 402, the pressure sensor 403 is connected to the display screen 406 signal, and when inspecting the cable, the magnetic pressure damage detection device is placed on the positive side of the detection support tube 203 On the ground above, start the electromagnet 404, which will apply a pressure to the pressure sensor 403 through the transmission rod 405, and the magnetic interaction force between the electromagnet 404 and the iron block 205 will increase the pressure applied by the electromagnet 404 to the pressure sensor 403. The pressure data detected by the pressure sensor 403 will be transmitted to the display screen 406, and the display screen 406 will display the pressure data for relevant technical personnel to view. The relevant technical personnel can calculate the magnetic interaction force exerted on the pressure sensor 403 based on the pressure data measured by the pressure sensor 403, and then determine whether the anti-corrosion outer sheath 201 is damaged. Therefore, through the setting of the magnetic pressure damage inspection part, the magnetic pressure damage inspection part can assist the relevant technical personnel to complete the inspection work quickly and accurately, thereby further improving the inspection efficiency and accuracy.

[0033] The third implementation method:

[0034] Figure 6-9A high-safety anti-corrosion cable is shown. Different from the second embodiment, the anti-corrosion protection component also includes a water-conducting layer 210 located inside the anti-corrosion outer sheath 201 and outside the cable body 001. The water-conducting layer 210 is set in a circular tube shape. The detection support tube 203 passes through the water-conducting layer 210 and is movably connected thereto. Each connecting hole 207 is filled with a water-conducting filling block 211. The lower part of the live seal linkage plate 204 is also filled with water-conducting particles 212. The two ends of the water-conducting filling block 211 are respectively attached to the water-conducting layer 210 and the water-conducting particles 212. The water-conducting layer 210 and the water-conducting filling block 211 are made of water-absorbing and breathable materials. The water-conducting filling block 211 is made of water-absorbing material, the water-absorbing performance of the wet-swelling top plate ball 206 is stronger than that of the water-conducting particles 212, the water-absorbing performance of the water-conducting particles 212 is stronger than that of the water-conducting filling block 211, and the water-absorbing performance of the water-conducting filling block 211 is stronger than that of the water-conducting layer 210. When the anti-corrosion outer sheath 201 is damaged and causes moisture in the soil to penetrate into the inner side of the anti-corrosion outer sheath 201 through the damaged area, the water-conducting layer 210, the water-conducting filling block 211, and the water-conducting particles 212 absorb and guide the wet-swelling top plate ball 206, thereby accelerating the expansion of the wet-swelling top plate ball 206, increasing the expansion rate of the wet-swelling top plate ball 206, and further improving the practicality of the anti-corrosion protection component.

[0035] See also Figure 6 The anti-corrosion protection component also includes an inner waterproof layer 213 located on the inner side of the water-conducting layer 210 and on the outer side of the cable body 001. The inner waterproof layer 213 is made of a sealing waterproof material. The two ends of the inner waterproof layer 213 are respectively sealed and fixedly connected to the two end sealing rings 202. The inner waterproof layer 213 can seal the cable body 001 to prevent moisture from penetrating into the inner side of the anti-corrosion outer sheath 201 and damaging the cable body 001.

[0036] See also Figure 8-9 The anti-corrosion protection component also includes an anti-corrosion replacement sheet 301 matching the anti-corrosion outer sheath 201 and a pair of seam sealing sheets 302. The anti-corrosion replacement sheet 301 is provided with a pair of through-tube half holes 303 matching the detection support tube 203, and one end of the seam sealing sheet 302 is provided with a cartridge half hole 304 matching the detection support tube 203. The length of the anti-corrosion replacement sheet 301 is equal to the length of the anti-corrosion outer sheath 201, and the length of the seam sealing sheet 302 is equal to half the length of the anti-corrosion replacement sheet 301. The material and thickness of the anti-corrosion replacement sheet 301 and the seam sealing sheet 302 are the same as those of the anti-corrosion outer sheath 201, and the width of the anti-corrosion replacement sheet 301 matches the circumference of the outer ring of the end sealing ring 202.

[0037] When the inspection result shows that the anti-corrosion outer sheath 201 is damaged and needs to be replaced, the damaged anti-corrosion outer sheath 201 is peeled off, and then the anti-corrosion replacement sheet 301 is wound along the outer wall of the end sealing link 202, and the through-tube half hole 303 is aligned with the detection support tube 203. Since the width of the anti-corrosion replacement sheet 301 matches the circumference of the outer ring of the end sealing link 202, the anti-corrosion replacement sheet 301 can be wound around once, and the anti-corrosion replacement sheet 301 after winding will be in the shape of a round tube that matches the anti-corrosion outer sheath 201, and the winding The anti-corrosion replacement sheet 301 can be fitted with the detection support tube 203 through the tube half hole 303, and the anti-corrosion replacement sheet 301 and the two end sealing rings 202 are sealed and fixedly connected using an adhesive. The anti-corrosion replacement sheet 301 treated in this way can be regarded as a new anti-corrosion outer sheath 201, which can replace the anti-corrosion outer sheath 201 to protect the cable body 001. Then, the two sealing seals 302 are placed on the butt joints at both ends of the anti-corrosion replacement sheet 301 (the two ends of the anti-corrosion replacement sheet 301 here refer to the tube-through holes provided on the anti-corrosion replacement sheet 301). The two ends of the half hole 303), and the cartridge half hole 304 on the sealing seal sheet 302 is aligned with the detection support tube 203, and finally, the sealing seal sheet 302 and the anti-corrosion replacement sheet 301 are sealed and fixedly connected with an adhesive to achieve a sealing effect on the butt joints at both ends of the anti-corrosion replacement sheet 301, so that the maintenance and replacement of the anti-corrosion outer sheath 201 can be completed. Therefore, through the arrangement of the anti-corrosion replacement sheet 301, the sealing seal sheet 302, etc., the anti-corrosion outer sheath 201 can be replaced separately after it is damaged. There is no need to replace the entire anti-corrosion protection component, and the anti-corrosion outer sheath 201 is very convenient to replace, which can improve the maintenance efficiency of the cable, reduce the maintenance cost of the cable, and greatly improve the practicality of the anti-corrosion protection component. In addition, after the seam sealing sheet 302 and the anti-corrosion replacement sheet 301 are sealed and fixed with an adhesive, the connection between the seam sealing sheet 302 and the detection support tube 203 (at the half hole 304 of the cartridge) can be sealed in a reasonable manner to ensure the sealing of the connection between the seam sealing sheet 302 and the detection support tube 203.

[0038] See also Figure 6-7The anti-corrosion protection component also includes a fixed ring 214 fixedly sleeved on the outer wall of the cable body 001, and the top of the fixed ring 214 is fixedly connected with a screw seat 215, and the screw seat 215 is set to a round tube shape matching the detection support tube 203. The detection support tube 203 is threadedly connected to the screw seat 215, and the screw seat 215 penetrates the inner waterproof layer 213 and is sealed and fixedly connected thereto. The bottom end of the detection support tube 203 is set to an opening shape, and the bottom end of the detection support tube 203 is provided with a bottom plate 217 matching therewith, and the connection between the bottom plate 217 and the detection support tube 203 is a detachable sealed fixed connection. The fixing ring 214 and the screw seat 215 can play a good role in fixing the detection support tube 203, thereby improving the stability of the detection support tube 203. When the inspection result shows that the anti-corrosion outer sheath 201 is damaged and needs to be replaced, after peeling off the anti-corrosion outer sheath 201, rotate the detection support tube 203 to separate the detection support tube 203 from the screw seat 215, and then remove the detection support tube 203. Then, remove the bottom plate 217, and replace the wet-swelling top plate ball 206 and the water-conducting particles 212, so that the wet-swelling top plate ball 206 is easy to replace, thereby improving the practicality of the anti-corrosion protection component.

[0039] See also Figure 7 An observation insert 216 is embedded through the outer wall of the top end of the detection support tube 203. The observation insert 216 is made of transparent corrosion-resistant material. When the inspection result shows that the anti-corrosion outer sheath 201 is damaged, the surface soil is dug until the top end of the detection support tube 203 leaks out, and then the situation inside the detection support tube 203 is observed through the observation insert 216 to check whether the magnetic isolation plate 209 swings upward, which can serve to verify the inspection results.

[0040] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
