Description

Technical Field

[0001] The wear-resistant cable involved in the present invention particularly relates to a wear-resistant cable applied in the field of cables. Background Art

[0002] A cable is a wire used to transmit electric energy, signals or data, usually composed of one or more mutually insulated wires. Cables play a crucial role in modern society and are widely used in fields such as electricity, communication, transportation, and construction.

[0003] In cities, cables are mainly laid underground, and the more popular way is to lay cables using cable tunnels. Cable tunnels can not only protect cables from external damage but also facilitate inspection and maintenance. This laying method has the characteristics of one-time construction investment, cable brackets are provided in the tunnel, and only regular inspections are required after completion.

[0004] However, during the process of moving and laying cables in cable tunnels, the protective layer of the cable will continuously contact and rub against the inner wall of the cable tunnel during movement, thereby causing frictional damage. Especially at the turning positions of the cable tunnel, the cable will suffer greater frictional damage. Therefore, how to reduce the frictional damage of the cable during construction and laying and ensure its service life is one of the urgent problems to be solved currently. Summary of the Invention

[0013] As a further improvement of this application, the avoidance protection regulation unit includes an avoidance instruction receiving module. The input end of the avoidance instruction receiving module is respectively signal-connected to the laying avoidance processing unit and the abnormal position avoidance unit. The output end of the avoidance instruction receiving module is connected to an avoidance status processing module. The output end of the avoidance status processing module is connected to a micro-avoidance module and a full-avoidance module. The output ends of the micro-avoidance module and the full-avoidance module are both signal-connected to the wear resistance unit.

DETAILED DESCRIPTION

[0032] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1 - Figure 10 A wear-resistant cable is shown, which comprises a cable body 1, a plurality of wear-resistant protective sleeves 2 which are sleeved on the outside of the cable body 1 and connected end to end, and a handheld laying controller 11 which is signal-connected to the cable body 1 and the wear-resistant protective sleeve 2. A protective cavity 21 is provided in the wear-resistant protective sleeve 2, a plurality of protective electromagnetic rings 4 are fixedly connected to the side of the protective cavity 21 close to the cable body 1, and a plurality of avoidance electromagnetic rings 3 which are located at positions corresponding to the protective electromagnetic rings 4 are fixedly connected to the inner wall of the protective cavity 21 which is away from the cable body 1.

[0035] The handheld laying controller 11 is equipped with a laying avoidance control system. The laying avoidance control system includes a laying avoidance processing unit. The input end of the laying avoidance processing unit is connected to a laying data import unit, a cable traction position acquisition unit, a traction speed calculation unit, and a status acquisition unit. The output end of the laying avoidance processing unit is connected to an avoidance protection control unit, a wear resistance unit, a laying display unit, and an abnormal alarm unit;

[0036] The input end of the laying data import unit is signal-connected to the signal access end provided on the handheld laying controller 11. The input end of the cable traction position acquisition unit is signal-connected to the positioner provided at the end of the cable body 1. The input end of the traction speed calculation unit is respectively signal-connected to the laying data import unit and the cable traction position acquisition unit. The input end of the status acquisition unit is signal-connected to the pressure probe provided in the protection chamber 21;

[0037] The output end of the avoidance protection control unit is signal-connected to the wear resistance unit. The output end of the wear resistance unit is respectively signal-connected to the avoidance electromagnetic ring 3 and the protection electromagnetic ring 4. The output end of the laying display unit is signal-connected to the display provided at the front end of the handheld laying controller 11. The output end of the abnormal alarm unit is signal-connected to the alarm provided on the cable body 1. Through the settings of the wear-resistant protective sleeve 2, the avoidance electromagnetic ring 3, the protection electromagnetic ring 4, and the laying avoidance control system, on the one hand, it can increase the wear resistance of the cable body 1 during the laying process in the cable tunnel, avoid the friction generated by the laying movement of the cable body 1 from directly acting on the protective layer of the cable body 1, and effectively reduce the friction damage of the cable body 1 during the laying process. On the other hand, when the cable body 1 moves to the turning position of the cable tunnel, it can effectively control the avoidance deformation of the wear-resistant protective sleeve 2. By reducing the outer diameter of the wear-resistant protective sleeve 2 at the turning point, it effectively realizes the non-contact turning effect of the cable body 1 and the wear-resistant protective sleeve 2, effectively avoids the direct contact of the wear-resistant protective sleeve 2 with the turning position of the cable tunnel, reduces the friction damage caused by the laying turning of the cable body 1, ensures its safety during the laying process, and at the same time can reduce the laying difficulty of the cable body 1 by reducing the turning friction force, improve the laying efficiency, and thus effectively ensure the service life of the cable body 1 and promote the economic benefits during the laying process of the cable body 1.

[0038] Figure 1 - Figure 10It is shown that the number of the avoidance electromagnetic rings 3 and the protection electromagnetic rings 4 is at least three, and they are evenly distributed in the protection cavity 21. An outer insulation connecting strip 31 is fixedly connected between two adjacent avoidance electromagnetic rings 3, and an inner insulation connecting strip 41 is fixedly connected between two adjacent protection electromagnetic rings 4. The settings of the outer insulation connecting strip 31 and the inner insulation connecting strip 41 can reduce the manufacturing and maintenance difficulties of the wear-resistant protection sleeve 2, and can also effectively improve the recycling efficiency of the cable body 1 and the protection electromagnetic rings 4 after the wear-resistant protection sleeve 2 is damaged. Moreover, the limitation of the number of the avoidance electromagnetic rings 3 and the protection electromagnetic rings 4 can effectively ensure the effective control of different avoidance methods, and effectively promote the environmental adaptability of the cable body 1 during the laying process.

[0039] Figure 2 It is shown that the output end of the laying avoidance processing unit is also connected with an abnormal marking unit and an abnormal position avoidance unit. The output end of the abnormal marking unit is in signal connection with the laying display unit, and the output end of the abnormal position avoidance unit is in signal connection with the avoidance protection regulation unit. The settings of the abnormal marking unit and the abnormal position avoidance unit can enable the cable body 1 and the wear-resistant protection sleeve 2 to effectively cope with the problem of foreign objects existing in the cable tunnel. On the one hand, it can mark and display the position of the foreign object, and on the other hand, it can generate effective avoidance control for the wear-resistant protection sleeve 2 when the cable body 1 moves to the position of the foreign object, avoiding the direct contact and friction between the wear-resistant protection sleeve 2 and the foreign object, causing damage or scratches to the wear-resistant protection sleeve 2, further promoting the safety of the cable body 1 during the laying process, reducing the damage during the laying process, and ensuring the stability of the performance of the cable body 1 during subsequent applications.

[0040] Figure 2 It is shown that the avoidance protection regulation unit includes an avoidance instruction receiving module. The input end of the avoidance instruction receiving module is in signal connection with the laying avoidance processing unit and the abnormal position avoidance unit respectively. The output end of the avoidance instruction receiving module is connected with an avoidance state processing module. The output end of the avoidance state processing module is connected with a micro-avoidance module and a full-avoidance module. The output ends of the micro-avoidance module and the full-avoidance module are both in signal connection with the wear-resistant resistance unit. The cooperation of the micro-avoidance module and the full-avoidance module can effectively realize the use conditions of the laying situation of the cable body 1 in different states. While reducing the frictional damage between the cable body 1 and the wear-resistant protection sleeve 2 and improving its wear resistance, it can also effectively promote the avoidance intelligence and avoidance application range of the cable body 1 during the laying process.

[0041] Figure 1 - Figure 8It is shown that communication components 5 are provided on the left and right inner walls of the protection cavity 21. The communication components 5 include communication plates 51 fixedly connected to the left and right inner walls of the protection cavity 21. A plurality of uniformly distributed communication pipes 52 are fixedly connected in the communication plates 51. Adjacent protection cavities 21 are connected through the communication pipes 52. The setting of the communication components 5 can effectively realize the connection of the protection cavities 21 of the wear-resistant protective sleeve 2 connected end to end. Furthermore, when controlling the friction avoidance deformation of the wear-resistant protective sleeve 2, it can effectively dredge and relieve the pressure in the protection cavity 21 after the avoidance deformation, avoiding elastic damage caused by excessive pressure. And under the dredging effect of the pressure, to a certain extent, it can promote the wear-resistant protective sleeve 2 on both adjacent sides of the wear-resistant protective sleeve 2 that generates avoidance deformation to generate an outer diameter expansion deformation, and improve the avoidance effect by increasing the outer diameter difference, further reducing the friction contact area and reducing friction damage.

[0042] Figure 4 - Figure 8 It is shown that the protection cavity 21 is filled with a mixed filler of inert gas and insect repellent essence, and the filling saturation of the inert gas in the protection cavity 21 is 65% - 75%. The setting of the mixed filler can, on the one hand, ensure the safety of the cable body 1 when the wear-resistant protective sleeve 2 is damaged, and on the other hand, through the smell emission of the insect repellent essence, reduce the continuous damage to the cable body 1 caused by underground organisms, play an effective insect repellent effect, avoid the approach of snakes, insects, rats and ants, and extend the service life of the cable body 1. And when the wear-resistant protective sleeve 2 is damaged during the laying process of the cable body 1, through the smell emission of the insect repellent essence, to a certain extent, it can send a damage reminder to the laying personnel, facilitating the laying personnel to adjust the functionality of the laying avoidance control system through the handheld laying controller 11, avoiding continuous damage.

[0043] Figure 1 - Figure 10It shows that when the cable body 1 is used for laying in a cable tunnel, the laying personnel first start the handheld laying controller 11, and then start the laying avoidance control system, so that the laying avoidance processing unit starts the wear-resistant resistance unit. The wear-resistant resistance unit controls the avoidance electromagnetic ring 3 and the protection electromagnetic ring 4 to generate a repulsive electromagnetic force, so that it maintains a supporting and expanding effect on the protection cavity 21, effectively ensuring the flexibility of the cable body 1 while promoting its supporting strength and wear resistance. Then, the laying personnel first import the cable tunnel route data for laying the cable body 1 and the basic data of the cable body 1 through the signal access terminal on the handheld laying controller 11 into the laying data import unit. The laying data import unit converts these data and transmits them to the laying avoidance processing unit and the traction speed calculation unit. After receiving the data, the laying avoidance processing unit synchronously transmits the data to the laying display unit, and the laying display unit displays a schematic diagram of the cable tunnel for laying the cable body 1 in this construction. Then, the radiation personnel install a locator signal-connected to the handheld laying controller 11 at the traction end of the cable body 1, use the traction device to introduce the traction end of the cable body 1 into the cable tunnel, and the locator transmits the movement data generated by the cable body 1 in the cable tunnel to the cable traction position acquisition unit. The cable traction position acquisition unit transmits the positioning data to the laying avoidance processing unit and the migration speed calculation unit. The laying avoidance processing unit transmits the laying movement data of the cable body 1 in the cable tunnel to the laying display unit according to the movement data of the locator. At the same time, after the traction speed calculation unit receives the data transmitted by the laying data import unit and the cable traction position acquisition unit, it calculates the actual laying speed of the cable body 1 and then transmits it to the laying avoidance processing unit;

[0044] After receiving the relevant data transmitted by the laying data import unit, the traction speed calculation unit, and the cable traction position acquisition unit, the laying avoidance processing unit processes and judges the actual movement data of the cable body 1 in the cable tunnel. Then, it effectively judges the cooperation mode between each wear-resistant protective sleeve 2 and the turning position of the cable tunnel during the continuous laying movement of the cable body 1. Then, it transmits the corresponding avoidance instruction to the avoidance instruction receiving module of the avoidance protection control unit. The avoidance instruction receiving module transmits the avoidance instruction data to the avoidance state processing module. The avoidance state processing module transmits the full avoidance control instruction to the full avoidance module. The full avoidance module feeds back the instruction to the wear-resistant resistance unit, so that the current passing through the avoidance electromagnetic ring 3 and the protection electromagnetic ring 4 in the protection cavity 21 of the wear-resistant resistance unit decreases, thereby reducing the electromagnetic repulsion force between them. Under the action of the elastic recovery of the wear-resistant protective sleeve 2, the wear-resistant protective sleeve 2 moving to the turning position of the cable tunnel will generate a full avoidance shrinkage deformation. Then, under the retention of the larger outer diameters of the two adjacent wear-resistant protective sleeves 2 that cooperate with it, the wear-resistant protective sleeve 2 located at the cable turning position can be prevented from directly contacting the inner wall of the cable tunnel turning. Thus, while reducing the friction force and promoting the laying efficiency of the cable body 1, it can also effectively reduce the friction damage of the cable body 1 at the cable tunnel turning position, ensure the safety of the cable body 1 during the laying process, and improve the stability of the subsequent performance of the cable body 1.

[0045] And while the laying avoidance processing unit controls the wear-resistant protective sleeve 2 moving to the turning position of the cable tunnel to generate a full avoidance shrinkage deformation through the avoidance protection control unit, the pressure probe in the protection cavity 21 will also transmit the pressure data generated by each wear-resistant protective sleeve 2 during the movement to the state acquisition unit. The state acquisition unit transmits the pressure data to the laying avoidance processing unit. The laying avoidance processing unit can judge the effect of generating full avoidance of the wear-resistant protective sleeve 2 moving to the turning position of the cable tunnel through the avoidance protection control unit according to the laying movement state of the cable body 1 in the cable tunnel and the feedback of the pressure data at each stage.

[0046] When it is determined that the full avoidance effect is poor, that is, the actual pressure in the protection cavity 21 at the cable tunnel turning position is greater than the theoretical pressure after the full avoidance diameter reduction, and the difference exceeds the standard value range, it indicates that the outer end of the wear-resistant protective sleeve 2 still abuts against the inner wall of the cable tunnel turning, forming a frictional extrusion effect. Therefore, the laying avoidance processing unit will continue to transmit an avoidance instruction to the avoidance instruction receiving module in the avoidance protection control unit. After receiving the modified avoidance instruction, the avoidance instruction receiving module will transmit it to the avoidance state processing module, and the avoidance state processing module will transmit the instruction to the full avoidance module. The full avoidance module transmits instruction data to the wear-resistant resistance unit, causing the wear-resistant resistance unit to continue to reduce the current input into the avoidance electromagnetic ring 3 and the protection electromagnetic ring 4, further reducing the electromagnetic repulsive force between the avoidance electromagnetic ring 3 and the protection electromagnetic ring 4. Under the elastic recovery effect of the wear-resistant protective sleeve 2, it plays a further role in full avoidance diameter reduction. The inert gas in the protection cavity 21 moves to the adjacent protection cavity 21 under the drainage of the communication plate 51 and the communication pipe 52, and then further increases the outer diameter of the adjacent wear-resistant protective sleeve 2, further increasing the outer diameter difference between the wear-resistant protective sleeve 2 with full avoidance diameter reduction and the adjacent wear-resistant protective sleeve 2. As a result, when it moves to the cable tunnel turning position, it can rely on the support of the adjacent wear-resistant protective sleeve 2 to further reduce its contact area with the inner wall of the cable tunnel turning, effectively reducing the frictional force and the frictional damage to the wear-resistant protective sleeve 2, ensuring the safety of the cable body 1 during the laying construction process;

[0047] When it is determined that the full avoidance effect is good, the avoidance control of the avoidance protection control unit will be continued, and at the same time, laying data will be output to the laying display unit, enabling the laying personnel to effectively view the image of the cable body 1 laid in the cable tunnel through the display.

[0048] During the laying and movement of the cable body 1, the pressure probe in the protection cavity 21 will continuously transmit the pressure data to the state acquisition unit. After the laying avoidance processing unit receives the pressure data transmitted by the state acquisition unit, the laying avoidance processing unit analyzes and processes the pressure data. When the cable body 1 moves to a certain position in the cable tunnel, the pressure data in the wear-resistant protective sleeve 2 will produce a large growth fluctuation, indicating that there is a foreign object at this position in the cable tunnel. Therefore, in order to avoid friction damage or even scratches on the wear-resistant protective sleeve 2 caused by foreign objects, the laying avoidance processing unit synchronously transmits the foreign object position data to the abnormal position avoidance unit and the abnormal marking unit. The abnormal position avoidance unit transmits the foreign object data to the avoidance instruction receiving module in the avoidance protection control unit. The avoidance instruction receiving module transmits the foreign object data to the avoidance state processing module. The avoidance state processing module sends an instruction to the micro avoidance module, so that the micro avoidance module sends micro avoidance data through the wear resistance unit, and the wear resistance unit controls the wear-resistant protective sleeve 2 moved to the position. The avoidance electromagnetic ring 3 and the protection electromagnetic ring 4 produce a current reduction effect in sequence according to the moving speed and along the laying direction, and then effectively according to the position of the avoidance electromagnetic ring 3 and the protection electromagnetic ring 4, the wear-resistant protective sleeve 2 is prompted to produce a local contraction effect, which can effectively play a micro-avoidance effect on foreign objects, and also has an adjustment effect on a single set of avoidance electromagnetic rings 3 and protection electromagnetic rings 4, reducing the amount of inert gas in the protection cavity 21 flowing to the adjacent protection cavity 21, thereby effectively ensuring the amplitude of the change in the outer diameter of the wear-resistant protective sleeve 2 at this time, effectively ensuring the smoothness and stability of the laying movement of the cable body 1, effectively avoiding further damage to the wear-resistant protective sleeve 2 caused by foreign objects due to the change in the outer diameter, and effectively realizing the targeted avoidance action of the wear-resistant protective sleeve 2 to foreign objects, and the abnormal marking unit will also transmit the foreign object data to the laying display unit, and display the location of the foreign object in the cable tunnel to the laying personnel through the display, so as to facilitate the laying personnel to deal with the foreign object in time and avoid the laying damage of the cable body 1 caused by the continued existence of foreign objects.

[0049] During the laying and movement of the cable body 1, after the pressure probe transmits the data of the reduced pressure in the protective cavity 21 to the status acquisition unit, the status acquisition unit transmits the reduced pressure data to the laying avoidance processing unit. The laying avoidance processing unit determines that the wear-resistant protective sleeve 2 is damaged at this time, and then transmits the abnormal data to the abnormal alarm unit. The abnormal alarm unit activates the alarm and transmits the damage alarm to the laying personnel, so that the laying personnel can check the abnormal position in time to avoid causing continuous damage to the subsequent wear-resistant protective sleeve 2. In addition, due to the breakage of the wear-resistant protective sleeve 2, the inert gas and insect repellent essence in the protective cavity 21 will scatter. On the one hand, it can disperse underground organisms. On the other hand, it can provide odor guidance when the laying personnel check the abnormality, thereby improving the efficiency of the laying personnel in handling the abnormality.

[0050] After the laying of the cable body 1 is completed, the laying personnel recover the locator set at the end of the cable body 1 for the application of the next laying. Then, the laying personnel connect the signal end and the control end of the cable body 1. While maintaining the normal communication transmission of the cable body 1, it can also supply power to the avoidance electromagnetic ring 3, the protection electromagnetic ring 4, and the pressure probe in the wear-resistant protective sleeve 2, and connect the signal wire harness of the pressure probe to the control end of the cable body 1. It can maintain the protective effect of the wear-resistant protective sleeve 2 on the cable body 1 through the control end of the cable body 1, and the pressure data transmitted by the pressure probe in the subsequent wear-resistant protective sleeve 2 is convenient for the control end of the cable body 1 to judge the application environment and state of the cable body 1, effectively playing an auxiliary maintenance role. After abnormal pressure data appears, it can timely send feedback of the pressure data to the control end of the cable body 1, enabling the maintenance personnel to timely maintain and repair the cable body 1. And when the wear-resistant protective sleeve 2 is broken, it can also avoid direct damage to the cable body 1 caused by underground organisms through the repelling effect of the insect repellent essence, further extending the service life of the cable body 1 and promoting the economic benefits of the application of the cable body 1.

[0051] When replacing the cable body 1, the laying personnel can use the auxiliary device to draw out the cable body 1 from the wear-resistant protective sleeve 2, and then recover the wear-resistant protective sleeve 2 to reduce waste of resources.

[0052] The second implementation mode:

[0053] Figure 1 - Figure 10 A wear-resistant cable is shown. Avoidance and holding components 6 are arranged on both the left and right sides of the protection cavity 21 and are matched with the communication components 5. The avoidance and holding components 6 include a pair of dredging sliding rings 64 slidably arranged in the protection cavity 21. A plurality of blocking springs 65 are fixedly connected to one end of each of the two communication plates 51 close to each other. One end of the blocking spring 65 away from the communication plate 51 is fixedly connected to a dredging sliding ring 64 matched with the communication plate 51;

[0054] At one end of the two dredging slip rings 64 close to each other, there is an annular strip 62. A plurality of connecting blocks 61 are fixedly connected to the outer end of the annular strip 62, and the outer end of the connecting block 61 is fixedly connected to the inner wall of the protection cavity 21 on the side away from the cable body 1. The setting of the avoidance and maintenance component 6 can, on the one hand, increase the compressive performance of the wear-resistant protective sleeve 2, ensure the pressure stability in the protection cavity 21, and avoid the complete pressure relief deformation of the protection cavity 21 caused by the action of the communication component 5 due to avoidance or other external forces, which may damage the avoidance electromagnetic ring 3 and the protection electromagnetic ring 4 inside it, effectively improving the durability and compressive resistance of the wear-resistant protective sleeve 2. On the other hand, when the wear-resistant protective sleeve 2 generates avoidance deformation and causes excessive pressure in the protection cavity 21, it can play an automatic unlocking and conduction role, effectively realizing the self-regulation of the pressure in the protection cavity 21, further reducing the damage of the wear-resistant protective sleeve 2, and promoting the use performance of the wear-resistant protective sleeve 2.

[0055] Figure 1 - Figure 9 It is shown that a plurality of drainage holes corresponding to the communication pipes 52 are provided on the dredging slip ring 64. A plurality of stepped plugging columns 63 that cooperate with the drainage holes are fixedly connected to both ends of the two annular strips 62 away from each other. The stepped plugging columns 63 can effectively block the drainage holes on the dredging slip ring 64. Then, with the cooperation of the plugging spring 65 and the pressure in the protection cavity 21, the self-regulation effect of the pressure in the protection cavity 21 is realized, promoting the functionality and durability of the wear-resistant protective sleeve 2.

[0056] Figure 1 - Figure 10It is shown that when the wear-resistant protective sleeve 2 produces a micro-avoidance deformation, due to the effect of local deformation and the unsaturated filling of the inert gas in the protective cavity 21, the pressure generated in the protective cavity 21 at this time cannot resist the elastic extension force of the blocking spring 65, so it will not cause the movement of the dredging slip ring 64, so that the step blocking column 63 can continue to maintain the continuous blocking effect on the drainage hole on the dredging slip ring 64, avoiding the inert gas in the protective cavity 21 at this time from flowing toward the adjacent protective cavity 21, thereby reducing the outer diameter difference between the wear-resistant protective sleeve 2 and the adjacent wear-resistant protective sleeve 2, maintaining the smooth movement of the cable body 1, and effectively ensuring the flexibility and manufacturing strength of the wear-resistant protective sleeve 2 at this time; when the wear-resistant protective sleeve 2 produces a full avoidance shrinking deformation, the overall deformation will cause the pressure in the protective cavity 21 to increase, and the pressure at this time can effectively resist the elastic extension force of the blocking spring 65, pushing the dredging slip ring 64 to produce a movement effect in the protective cavity 21, so that the dredging slip ring 64 produces a movement effect toward When moving to the side away from the step blocking column 63, the blocking spring 65 is compressed, and the step blocking column 63 is separated from the drainage hole on the dredging slip ring 64, releasing the blocking effect, so that the inert gas in the protective cavity 21 can move to the adjacent protective cavity 21, effectively relieving the pressure in the protective cavity 21, and promoting the difference in outer diameter between the wear-resistant protective sleeve 2 that fully avoids shrinkage deformation and its adjacent wear-resistant protective sleeve 2, so that it can effectively ensure that it does not contact the inner wall of the cable tunnel turning, reducing the friction damage caused by the turning; when the wear-resistant protective sleeve 2 is in a normal state, the elastic elongation force of the blocking spring 65 maintains the position of the dredging slip ring 64, and the step blocking column 63 maintains a continuous blocking effect on the drainage hole on the dredging slip ring 64, thereby effectively ensuring the pressure resistance of the wear-resistant protective sleeve 2, effectively protecting the cable body 1, and under the action of the unsaturated filling of the inert gas, the wear-resistant protective sleeve 2 has flexibility and can be effectively used for the laying of the cable body 1.

[0057] 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.
