Description

Technical Field

[0001] The present application relates to the technical field of cable trimming, and in particular to an automatic cable trimming device and method with an ice-melting function. Background Art

[0002] In a low temperature and high humidity environment, high-voltage power transmission lines will be covered with ice. Severe icing can cause pole tower collapse, wire breakage and other faults in the power transmission lines. These faults will affect the safe and reliable operation of the power system and cause large-scale power outages in the corresponding power grid, seriously affecting industrial and agricultural production and people's lives, and causing huge economic losses.

[0003] If a power transmission line has a wire breakage fault, due to the uneven ice coverage on the four-split wires of the power transmission line, the wires of the power transmission line are prone to breakage and overlap on the ground, causing the power transmission line to be unable to operate normally. It is necessary to cut the damaged wires to enable the power transmission line to operate normally. Considering the post-disaster maintenance cost and the working efficiency of the transmission line, the measure taken is to cut the broken wires and turn the four-split wires into three-split wires so that the power transmission line continues to work. However, under severe weather conditions, the method of using artificial high-altitude operations to cut the faulty power transmission line is inefficient, and due to the uneven ice coverage on the power transmission line, the wire cutting will cause other wires to have a torsional effect, seriously threatening the lives of high-altitude workers.

[0030] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described below are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] The automatic wire trimmer is an intelligent device commonly used in manufacturing and industrial automation. It is widely used in the fields of automobile manufacturing, aerospace, electronic equipment manufacturing, and home appliance production. It is often used to cut wires, cables, plastic pipes, etc. The design and use of automatic wire trimmers are crucial to the operational efficiency of the manufacturing industry and the effective maintenance of major infrastructure. The application of automated intelligent devices not only significantly improves work efficiency, reduces labor costs and labor intensity, but also effectively responds to work challenges in extremely harsh environments.

[0034] The key technical issues that need to be solved by the automatic wire cutting device mainly include: reducing time costs, reducing labor intensity to improve production efficiency and product accuracy and quality. For example, in the field of electronic manufacturing and electronic assembly, the automatic wire cutting device can be used to cut the wires and cables in electronic components, solving the accuracy and efficiency problems of cable cutting in the manufacturing process of electronic equipment. In the field of automobile manufacturing and assembly, the automatic wire cutting device is used to cut the wires in the automobile electrical system, solving the problems of accurate wire cutting and efficient production in automobile wiring harness processing. In the field of major engineering structures, the automatic cut-off device can be used to respond to emergencies under sudden failures or extreme weather conditions. It can help protect power grid equipment and prevent accidents or power outages caused by line failures. In bridge structures, the automatic cut-off device can be used for the maintenance and maintenance of bridge structures; for example, installing an automatic cut-off device in the main cable of the bridge can cut off the main cable in time when severe vibration or abnormal conditions occur, avoiding structural damage or safety accidents caused by vibration.

[0035] The automatic wire cutting devices currently used in the field of power transmission line engineering are usually used to protect power facilities, prevent accidents or quickly restore power supply. This automatic wire cutting device can monitor the current load of the transmission line. When the load of the transmission line exceeds the predetermined threshold, the current sensor on the automatic wire cutting device will accurately sense the current load and automatically cut off the power supply to prevent equipment damage or accidents caused by line overload. In addition, when a fault occurs in the transmission line, the automatic wire cutting device can quickly isolate the faulty part to prevent the fault from spreading to other parts, thereby minimizing the scope of power outage and improving power supply reliability. In addition, the existing automatic wire cutting devices are usually integrated with remote monitoring systems to achieve remote monitoring and control of transmission lines. The operation and maintenance personnel of the transmission line can understand the status of the transmission line in real time through the remote monitoring system and perform remote operations. The intelligent control algorithm built into the automatic wire cutting device analyzes and processes the sensor data in real time. Based on the preset logic and conditions, the automatic wire cutting device can respond quickly, such as cutting off the power supply, isolating the faulty section or restoring the power supply. Some automatic wire cutting devices also have an automatic recovery function. Once the fault is eliminated or the load returns to normal, the device can automatically restore power supply, reducing manual intervention and power outage time.

[0036] However, existing automatic wire-cutting device designs still have limitations when facing the special requirements of medium and heavy ice areas. For example, they may not be able to effectively cut damaged ice-covered wires, cannot suppress economic losses caused by torsion effects, and are not conducive to on-site maintenance after disasters.

[0037] The embodiments of the present application provide an automatic cable cutting device and method with an ice-melting function, which solves the technical problem that the existing manual cutting of broken transmission lines is inefficient and threatens the life safety of operators. The automatic cable cutting device and method with an ice-melting function can ensure the effective cutting of the conductors of the damaged transmission line, and can also flexibly adapt to the torsional effect of the conductors under different icing conditions to meet the needs of transmission lines in medium and heavy ice areas. Through the automatic cable cutting device and method with an ice-melting function, the damaged four-split conductor of the transmission line can be cut under severe weather conditions, avoiding the risks caused by manual high-altitude operations during the maintenance of the transmission line after a disaster; it also ensures efficient maintenance when multiple split conductors are damaged in medium and heavy ice areas, so that the stability and safety of the transmission line are guaranteed.

[0038] Embodiment 1:

[0039] Figure 1 This is a schematic structural diagram of an automatic cable trimming device with ice melting function described in an embodiment of the present application.

[0040] like Figure 1As shown, the embodiment of the present application provides an automatic cable trimming device with an ice melting function, comprising:

[0041] A thread trimming assembly, the thread trimming assembly includes a first thread trimming mechanism 12 and a second thread trimming mechanism 13 in a symmetrical structure;

[0042] The ice melting element 2 is arranged on the support column 3 and is used to detect the fault area of ​​the wire in the faulty cable and melt ice or snow on the cable where the fault area is located. The two ends of the support column 3 are respectively connected to the first wire cutting mechanism 12 and the second wire cutting mechanism 13.

[0043] It should be noted that the support column 3 is used to support the first wire cutting mechanism 12 and the second wire cutting mechanism 13, and secondly, to support the faulty cable. The first wire cutting mechanism 12 and the second wire cutting mechanism 13 can both cut the wires in the faulty cable. In this embodiment, the first wire cutting mechanism 12 and the second wire cutting mechanism 13 of the wire cutting assembly are symmetrically arranged so that the automatic wire cutting device with ice melting function can be effectively and firmly sheathed on the damaged sub-conductor. In addition, the torsional effect of the multiple split sub-conductors during the cutting process can be reduced, and the influence of the wire torsion on the lifting during the cutting process can be reduced.

[0044] like Figure 1 As shown, in the embodiment of the present application, the ice melting element 2 can be selected as a laser.

[0045] It should be noted that the ice-covered faulty cable is placed on the support column 3 by connecting the first wire cutting mechanism 12 and the second wire cutting mechanism 13 through the support column 3. The ice melting element 2 arranged on the support column 3 can effectively melt the ice on the wire in the fault area, making full preparations for the wire cutting work. Since the ice layer on the surface of the damaged wire is thick and it is not easy to cut the damaged wire, the automatic cable wire cutting device with ice melting function adopts the method of melting ice first and then cutting. When the laser beam of the ice melting element 2 irradiates the ice layer on the surface of the faulty cable, the laser energy will be absorbed and converted into heat energy, so that the temperature of the surface of the ice layer increases, and the ice layer begins to melt and fall off. Due to the high energy density and concentration of the laser beam, it can quickly melt and remove the ice layer, laying the foundation for cutting the damaged wire in the transmission line.

[0046] In the embodiment of the present application, the automatic cable trimming device with ice melting function detects the fault area of ​​the wire in the faulty cable through the ice melting element 2 and melts ice or snow on the faulty cable in the faulty area; then the wire in the faulty area is placed on the support column 3 and clamped and fixed by the first wire trimming mechanism 12 and the second wire trimming mechanism 13 to achieve the wire trimming of the faulty cable. The automatic cable trimming device with ice melting function can be used for the cutting of multi-split wires in medium and heavy ice areas, avoiding the risks caused by manual high-altitude operations during the maintenance of power transmission lines after snowstorms, and ensuring the efficient maintenance of multi-split wires in medium and heavy ice areas when they are damaged, so that the stability and safety of the power transmission lines are guaranteed.

[0047] The present application provides an automatic cable cutting device with ice melting function, comprising a cutting assembly, the cutting assembly including a first cutting mechanism and a second cutting mechanism which are symmetrically structured and used to cut the wires in the faulty cable; an ice melting element, which is arranged on a support column and used to detect the fault area of ​​the wires in the faulty cable and melt ice or snow on the faulty cable in the faulty area, and the two ends of the support column are respectively connected to the first cutting mechanism and the second cutting mechanism. Compared with the existing automatic cutting device, the automatic cable cutting device with ice melting function can be applied to ice-covered or snow-covered transmission lines, and the fault area of ​​the wires in the faulty cable on the transmission line is detected by the ice melting element, and the faulty cable in the faulty area is melted by the ice melting element; then the wires in the faulty area are placed on the support column and clamped and fixed by the first cutting mechanism and the second cutting mechanism to cut, so as to realize automatic cutting of the wires of the faulty cable. The automatic cable cutting device with ice melting function has high cutting efficiency, and solves the technical problem that the existing manual cutting of the broken transmission line is inefficient and threatens the life safety of the operators.

[0048] Figure 2 This is a schematic structural diagram from another perspective of the automatic cable trimming device with ice melting function described in an embodiment of the present application.

[0049] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the first wire cutting mechanism 12 and the second wire cutting mechanism 13 both include a wire cutting body 1 and a scissors body 7 arranged on the wire cutting body 1, and the first telescopic element 9 and the second telescopic element 14 are arranged on the wire cutting body 1 at the cutting edge of the scissors body 7. The first telescopic element 9 and the second telescopic element 14 are connected by a clip 10, and the clip 10 is used to clamp and fix the wire of the faulty cable to be cut, and one end of the first telescopic element 9 and the second telescopic element 14 are respectively connected to the two blades of the scissors body 7.

[0050] It should be noted that the working principle of the first wire cutting mechanism 12 and the second wire cutting mechanism 13 for cutting the wire is: the first telescopic element 9 and the second telescopic element 14 are retracted to drive the scissor body 7 to extend the wire clamped by the cutting clip 10 outside the wire cutting body 1. The danger caused by manual high-altitude operations is avoided, and the efficiency of post-disaster repair work is improved. In a low temperature and high humidity environment, high-voltage power transmission lines will be covered with ice, and severe icing will affect the safe and reliable operation of the power system. Due to the uneven ice coverage of cables with multiple split conductor faults on the transmission line, some conductors will break. At this time, it is necessary to cut the damaged conductors to ensure the normal operation of the power system. The traditional maintenance method uses manual high-altitude operations to cut the damaged conductors, and the extremely harsh environment will affect the safety of the staff. However, the automatic cable cutting device with ice melting function can effectively cut the damaged conductors in the medium and heavy ice areas through the ice melting element 2 and the scissor body 7. This not only avoids the staff from working at high altitude in harsh environments, but also ensures that the damaged conductors are cut in time under different climatic conditions to ensure the safe operation of the power system. In addition, the use of the automatic cable cutting device with ice-melting function can improve the efficiency of post-disaster power transmission line maintenance, reduce labor costs, and reduce the risk factor for workers during emergency repairs in harsh environments.

[0051] In the embodiment of the present application, the automatic cable cutting device with ice melting function can be effectively put on the damaged wire and reduce the influence of ice on the cutting process. The automatic cable cutting device with ice melting function has been carefully optimized in structure, and a cutting body 1 composed of two semicircular sub-cylinders is provided, so that the cutting body 1 is more compatible with the appearance of the power transmission line; and then it can be firmly put on the damaged wire through the clip 10, so that the scissors body 7 can cut the damaged wire. One of the semicircular sub-cylinders of the cutting body 1 is put on the damaged wire, and the other semicircular sub-cylinder is put on the intact wire. When the damaged wire is cut, the semicircular sub-cylinder connected to the lifting provides support force to prevent the wire torsion effect caused by uneven gravity distribution after the wire is cut. The support column 3 is equipped with an ice melting element 2 as an automatic deicing device, and the ice layer is melted by the laser beam of the ice melting element 2.

[0052] It should be noted that the ice melting principle of the ice melting element 2 is the absorption and conversion of energy emitted by the laser. When the light beam is irradiated onto the ice layer of the conductor, the energy of the laser will be absorbed and converted into heat energy, the surface temperature of the ice layer will rise, and the ice layer will gradually melt and drip. At the same time, due to the high density and concentration of laser energy, the ice layer can be effectively and quickly removed without damaging the power transmission line. Deicing before cutting the damaged conductor can speed up the process of cutting the damaged conductor and improve the efficiency of maintenance work.

[0053] like Figure 1 and Figure 2As shown, in one embodiment of the present application, a first elastic vibration-damping element 8 is provided on the wire cutting body 1 for suppressing vibration caused by the cutting process of the wire in the faulty cable.

[0054] It should be noted that the first elastic damping element 8 is provided on the wire cutting body 1 at both ends of the blade of the scissors body 7. The first elastic damping element 8 can be selected as a spring. In this embodiment, the first elastic damping element 8 can suppress the vertical vibration of the wire caused by the external environment during the cutting process. The automatic wire cutting device with ice melting function helps the automatic wire cutting device with ice melting function to de-ice the wire before cutting through the arrangement of the first elastic damping element 8 and the ice melting element 2, and effectively suppresses the vibration of the damaged sub-wire caused by the external environment during the cutting process.

[0055] In the embodiment of the present application, in a harsh environment, during the process of cutting the damaged wire, the wire will continue to vibrate due to the effect of wind. However, the automatic wire trimming device with ice melting function is equipped with a first elastic vibration reduction element 8 in the middle of the two ends of the wire trimming body 1, which can effectively reduce the wire vibration caused by the external environment, so that the automatic wire trimming device with ice melting function ensures that the wire trimming process is carried out stably and effectively, providing a guarantee for the maintenance of damaged power transmission lines.

[0056] like Figure 1 As shown, in one embodiment of the present application, the first wire cutting mechanism 12 and the second wire cutting mechanism 13 are further connected by a first fastener 6; and / or, the first wire cutting mechanism 12 and the second wire cutting mechanism 13 are provided with a hanging ear 4 for connecting to the wire in the faulty cable.

[0057] It should be noted that the hanging ear 4 can be fixed on the thread trimmer body 1 by welding.

[0058] Embodiment 2:

[0059] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides an automatic cable trimming device with an ice melting function, comprising a plurality of trimming modules, wherein two adjacent trimming modules are connected by a connecting assembly. Each trimming module comprises:

[0060] A thread trimming assembly, the thread trimming assembly includes a first thread trimming mechanism 12 and a second thread trimming mechanism 13 in a symmetrical structure;

[0061] The ice melting element 2 is arranged on the support column 3 and is used to detect the fault area of ​​the wire in the faulty cable and melt ice or snow on the cable where the fault area is located. The two ends of the support column 3 are respectively connected to the first wire cutting mechanism 12 and the second wire cutting mechanism 13.

[0062] It should be noted that the support column 3 is used to support the first wire cutting mechanism 12 and the second wire cutting mechanism 13, and secondly, to support the faulty cable. The first wire cutting mechanism 12 and the second wire cutting mechanism 13 can both cut the wires in the faulty cable. In this embodiment, the automatic wire cutting device for cables with ice melting function is illustrated with two wire cutting modules as a case study. The two wire cutting modules are respectively the first wire cutting module and the second wire cutting module with a symmetrical structure up and down. The first wire cutting module is connected to the second wire cutting module through a connecting component 5, so that the wire cutting module can reduce the torsional effect of multiple split sub-conductors during the cutting process. The first wire cutting mechanism 12 and the second wire cutting mechanism 13 of the wire cutting assembly are symmetrically arranged so that the automatic wire cutting device for cables with ice melting function can be effectively and firmly sheathed on the damaged sub-conductor. In addition, the torsional effect of multiple split sub-conductors during the cutting process can be reduced, and the influence of the wire torsion on the lifting during the cutting process can be reduced.

[0063] like Figure 1 As shown, in the embodiment of the present application, the ice melting element 2 can be selected as a laser.

[0064] It should be noted that the ice-covered faulty cable is placed on the support column 3 by connecting the first wire cutting mechanism 12 and the second wire cutting mechanism 13 through the support column 3. The ice melting element 2 arranged on the support column 3 can effectively melt the ice on the wire in the fault area, making full preparations for the wire cutting work. Since the ice layer on the surface of the damaged wire is thick and it is not easy to cut the damaged wire, the automatic cable wire cutting device with ice melting function adopts the method of melting ice first and then cutting. When the laser beam of the ice melting element 2 irradiates the ice layer on the surface of the faulty cable, the laser energy will be absorbed and converted into heat energy, so that the temperature of the surface of the ice layer increases, and the ice layer begins to melt and fall off. Due to the high energy density and concentration of the laser beam, it can quickly melt and remove the ice layer, laying the foundation for cutting the damaged wire in the transmission line.

[0065] In the embodiment of the present application, in a low temperature and high humidity environment, high-voltage power transmission lines may be covered with ice (uneven ice on the transmission lines of the power transmission lines). If the faulty conductor of the ice-covered transmission line is directly cut, the cut of the conductor will cause a torsion effect on other conductors on the transmission line. Therefore, the automatic cable cutting device with ice melting function first detects the fault area of ​​the conductor in the faulty cable through the ice melting element 2 and melts ice or snow on the faulty cable in the fault area; then the conductor in the fault area is placed on the support column 3 and clamped and fixed by the first cutting mechanism 12 and the second cutting mechanism 13 to cut the conductor, so as to cut the conductor of the faulty cable. The automatic cable cutting device with ice melting function can be used for cutting multiple split conductors in medium and heavy ice areas, avoiding the risks caused by manual high-altitude operations during the maintenance of the transmission line after the snowstorm, and ensuring the efficient maintenance of multiple split conductors in medium and heavy ice areas when they are damaged, so that the stability and safety of the transmission line are guaranteed.

[0066] The present application provides an automatic cable cutting device with ice melting function, comprising a plurality of cutting modules, two adjacent cutting modules are connected by a connecting assembly, each cutting module comprises a cutting assembly and an ice melting element, the cutting assembly comprises a first cutting mechanism and a second cutting mechanism in a symmetrical structure; the ice melting element is arranged on a support column and is used to detect the fault area of ​​the wire in the faulty cable and to melt ice or snow on the faulty cable in the faulty area, and the two ends of the support column are respectively connected to the first cutting mechanism and the second cutting mechanism. Compared with the existing automatic cutting device, the automatic cable cutting device with ice melting function can be applied to ice-covered or snow-covered transmission lines, and the fault area of ​​the wire in the faulty cable on the transmission line is detected by the ice melting element, and the faulty cable in the faulty area is melted by the ice melting element; then the wire in the faulty area is placed on the support column and clamped and fixed by the first cutting mechanism and the second cutting mechanism to cut, so as to realize automatic cutting of the wire of the faulty cable, and the automatic cable cutting device with ice melting function has high cutting efficiency, which solves the technical problem that the existing manual cutting of the broken transmission line is inefficient and threatens the life safety of the operators.

[0067] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the first wire cutting mechanism 12 and the second wire cutting mechanism 13 both include a wire cutting body 1 and a scissors body 7 disposed on the wire cutting body 1, and the wire cutting body 1 located at the cutting edge of the scissors body 7 is provided with a first telescopic element 9 and a second telescopic element 14, and the first telescopic element 9 and the second telescopic element 14 are connected by a clip 10, and the clip 10 is used to clamp and fix the wire of the faulty cable to be cut. One end of the first telescopic element 9 and the second telescopic element 14 are respectively connected to the two blades of the scissors body 7.

[0068] It should be noted that the first telescopic element 9 and the second telescopic element 14 are retracted to drive the scissor body 7 to extend the wire clamped by the shear clip 10 outside the wire cutting body 1. The danger caused by manual high-altitude operation is avoided, and the efficiency of post-disaster repair work is improved. In a low temperature and high humidity environment, high-voltage power transmission lines will be covered with ice, and severe icing will affect the safe and reliable operation of the power system. Due to the uneven ice coverage of cables with multiple split conductor faults on the transmission line, some conductors will break. At this time, it is necessary to cut the damaged conductors to ensure the normal operation of the power system. The traditional maintenance method uses manual high-altitude operation to cut the damaged conductors, and the extremely harsh environment will affect the safety of the staff. However, the cable automatic wire cutting device with ice melting function can effectively cut the damaged conductors in the medium and heavy ice areas through the ice melting element 2 and the scissor body 7. This not only avoids the staff from working at high altitude in harsh environments, but also ensures that the damaged conductors are cut in time under different climatic conditions to ensure the safe operation of the power system. In addition, the use of the cable automatic wire cutting device with ice melting function can improve the efficiency of post-disaster power transmission line maintenance, reduce labor costs, and reduce the risk factor of staff repairing in harsh environments.

[0069] In the embodiment of the present application, the automatic cable cutting device with ice melting function can be effectively put on the damaged wire and reduce the influence of ice on the cutting process. The automatic cable cutting device with ice melting function has been carefully optimized in structure, and a cutting body 1 composed of two semicircular sub-cylinders is provided, so that the cutting body 1 is more compatible with the appearance of the power transmission line; and then it can be firmly put on the damaged wire through the clip 10, so that the scissors body 7 can cut the damaged wire. One of the semicircular sub-cylinders of the cutting body 1 is put on the damaged wire, and the other semicircular sub-cylinder is put on the intact wire. When the damaged wire is cut, the semicircular sub-cylinder connected to the lifting provides support force to prevent the wire torsion effect caused by uneven gravity distribution after the wire is cut. The support column 3 is equipped with an ice melting element 2 as an automatic deicing device, and the ice layer is melted by the laser beam of the ice melting element 2.

[0070] It should be noted that the ice melting principle of the ice melting element 2 is the absorption and conversion of energy emitted by the laser. When the light beam is irradiated onto the ice layer of the conductor, the energy of the laser will be absorbed and converted into heat energy, the surface temperature of the ice layer will rise, and the ice layer will gradually melt and drip. At the same time, due to the high density and concentration of laser energy, the ice layer can be effectively and quickly removed without damaging the power transmission line. Deicing before cutting the damaged conductor can speed up the process of cutting the damaged conductor and improve the efficiency of maintenance work.

[0071] like Figure 1 and Figure 2As shown, in one embodiment of the present application, a first elastic vibration-damping element 8 is provided on the wire cutting body 1 for suppressing vibration caused by the cutting process of the wire in the faulty cable.

[0072] It should be noted that the first elastic damping element 8 is provided on the wire cutting body 1 at both ends of the blade of the scissors body 7. The first elastic damping element 8 can be selected as a spring. In this embodiment, the first elastic damping element 8 can suppress the vertical vibration of the wire caused by the external environment during the cutting process. The automatic wire cutting device with ice melting function helps the automatic wire cutting device with ice melting function to de-ice the wire before cutting through the arrangement of the first elastic damping element 8 and the ice melting element 2, and effectively suppresses the vibration of the damaged sub-wire caused by the external environment during the cutting process.

[0073] In the embodiment of the present application, in a harsh environment, during the process of cutting the damaged wire, the wire will continue to vibrate due to the effect of wind. However, the automatic wire trimming device with ice melting function is equipped with a first elastic vibration reduction element 8 in the middle of the two ends of the wire trimming body 1, which can effectively reduce the wire vibration caused by the external environment, so that the automatic wire trimming device with ice melting function ensures that the wire trimming process is carried out stably and effectively, providing a guarantee for the maintenance of damaged power transmission lines.

[0074] like Figure 1 As shown, in one embodiment of the present application, the first wire cutting mechanism 12 and the second wire cutting mechanism 13 are further connected by a first fastener 6; and / or, the first wire cutting mechanism 12 and the second wire cutting mechanism 13 are provided with a hanging ear 4 for connecting to the wire in the faulty cable.

[0075] It should be noted that the hanging ear 4 can be fixed to the thread trimmer body 1 by welding. The first fastener 6 can be a bolt, a screw, a pin, etc.

[0076] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the connecting assembly 5 includes a first clamping plate 15 and a second clamping plate 16 for clamping and connecting the wires in the faulty cable, and the first clamping plate 15 and the second clamping plate 16 are both provided with a plurality of grooves 11 for installing a tension detection element, and the tension detection element is used to detect the tension of the wires in the faulty cable; and / or, the first clamping plate 15 is tightly connected to the second clamping plate 16 via a second fastener 17.

[0077] It should be noted that the second fastener 17 can be selected as a bolt, a screw, a pin, etc. The tension detection element can be selected as a tension sensor. The tension detection element can monitor the change of the internal force of the wire. When the wire is damaged, the signal output by the tension detection element can be used to start the automatic wire cutting device with ice melting function immediately to repair the power transmission line. In this embodiment, the first clamping plate 15 and the second clamping plate 16 are connected by the second fastener 17 to form a first wire cutting module and a second wire cutting module that are symmetrical up and down. The wire cutting body 1 of the first wire cutting module and the second wire cutting module can meet the needs of multiple wires being simultaneously sleeved on the wire cutting body 1, and the scissor body 7 on each internal cylinder can work independently. It can make it possible to cut the damaged wire while suppressing the torsion effect of the intact wire. One of the semicircular sub-cylinders of the wire cutting body 1 is sleeved on the damaged wire, and the other semicircular sub-cylinder is sleeved on the intact wire. When the damaged wire is cut, the connected semicircular sub-cylinder provides support force to prevent the wire torsion effect caused by uneven gravity distribution after the wire is cut. The tension detection element can be placed on the groove 11 to detect whether the wire is damaged, so as to start the automatic wire cutting device with ice-melting function. At the same time, the symmetrical wire cutting body 1 design can reduce the torsion effect of the multi-split wires during the cutting process. The tension detection element allows the automatic wire cutting device with ice-melting function to monitor the stress condition of the wire in real time. For example, the tension detection element converts the detected tension change into an electrical signal and transmits it to the control system of the automatic wire cutting device with ice-melting function. The control system determines whether the detected tension is damaged or abnormal according to the set safety tension value, and whether to trigger the start of the wire cutting operation to protect the safety and stability of the wire and the entire power transmission system.

[0078] In the embodiment of the present application, the two wire cutting bodies 1 are connected by the first fastener 6. How to design the position of the first fastener 6 and the number of the first fastener 6 can make the wire cutting body 1 tightly connected. The design of the clip is to ensure a firm connection between the first telescopic element 9 and the second telescopic element 14 during the cutting process. The position of the groove 11 can be designed according to the need to more effectively monitor the damaged transmission line in a harsh environment.

[0079] In the embodiment of the present application, the automatic cable trimming device with ice-melting function can perform the cable trimming operation efficiently and accurately, while protecting the safety of the wires and the device itself.
