Description

Technical Field

[0001] The present invention relates to the field of application of electrical accessories, and particularly relates to an aerial repair device for repairing broken-strand overhead conductors. Background Art

[0002] The safety and stability of the operation of the power system determine the level of social production and life. Especially with the gradual expansion of the scale of power grid construction, the operation and maintenance of overhead lines become more important. If a fault occurs in the line, it may lead to the expansion of the accident scope, causing serious losses to power enterprises and society. Broken strands of conductors are a common fault existing in overhead lines. And this kind of malignant wire-breaking accident is directly caused by the broken strands of the line conductors. Such conductor broken-strand events will not only reduce the current-carrying capacity, but also greatly affect their tensile strength. Seriously threatening the safe operation of the transmission line.

[0003] Currently, the requirement for power supply reliability is very high. In addition, the workload of dropping the old conductor to the ground and reconnecting it after the conductor is powered off is too large. After binding, the old conductor needs to be erected again. Using aerial work to repair and wind the broken-strand conductors requires the assistance of an energized work vehicle. However, not all terrains are suitable for the entry of the energized work vehicle. In many fields and mountainous areas, the energized work vehicle cannot enter. The operators in the energized work vehicle require high skills, and the energized work vehicle is expensive. The protective clothing of the vehicle operators is greatly related to the temperature, humidity, and wind force in the weather. All these conditions need to be met to carry out energized work, making the energized work have great limitations. Summary of the Invention

Detailed implementation manners

[0030] In the description of the present invention, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically defined. In the embodiments of the present invention, all directional indications (such as up, down, left, right, front, back, top, bottom...) are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly. In addition, the terms "include" and "have" and any deformation thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products or devices.

[0031] In addition, the mention of "embodiment" in this document means that the specific features, structures, or characteristics described in connection with the embodiment may be included in at least one embodiment of the present invention. The occurrence of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] The applicant further analyzed the technical problems of the complex and highly limited repair technology for broken strands in overhead conductors and the reasons for the occurrence of conductor broken strands, and found that:

[0033] At the connection between the suspension clamp and the conductor, aluminum tape is tightly wound. Under long-term action, the aluminum tape may become loose, scale may be generated, or the surface may be oxidized, resulting in an abnormal increase in the contact resistance. When the overhead transmission line is affected by foreign objects such as bird damage and lightning strikes, the insulator string has an arc flashover. At this time, a short-circuit power frequency occurs, which continuously flows through the abnormal contact resistance and generates a large amount of heat during the flowing process. Until the temperature reaches the melting point of the aluminum conductor, the conductor is broken. Another situation is that the span and height difference of the pole section are unreasonable. During the construction process, due to thermal expansion and contraction, the sag between the conductors increases. Under the action of the external force of the wind, the conductors collide with each other, resulting in an interphase short circuit and an arc. Under the action of the current, when the temperature reaches the melting point of the aluminum conductor, the conductor is broken. Additionally, mechanical damage is caused to the conductors to be erected during the conductor stringing. Improper force by the workers or non-standard factory processes result in unqualified conductors at the factory. The construction personnel did not discover it in time. After the conductors are erected and under the action of a large current, the resistance at the damaged part of the conductor is smaller than other places, generating serious heat. Under the action of a large current, when the temperature reaches the melting point of the aluminum conductor, the conductor is also broken, etc.

[0034] When repairing broken-strand conductors, according to the different degrees of conductor damage, it can be divided into three methods: sawing off and re-crimping, repair, and winding. The operation methods are divided into two categories: aerial work and ground operation. Aerial work mainly focuses on repair and winding. For sawing off and re-crimping, it is better to perform the operation by lowering to the ground.

[0035] Due to the operation of overhead power lines being affected by harsh natural environments, strand breaks and abrasions occur during long-term use. This not only affects the normal operation of the lines but also poses certain safety hazards. In the modernization construction projects of our country, the importance attached to power grid construction is increasing. Only by ensuring the stability and safety of the operation of the power system can we promote the sustainable development of our country's economy. Strand breaks mainly occur near the wire hanging points and in the middle part of the wire. And the treatment of the middle part of the wire is the most difficult. Since overhead power lines are at a relatively high distance from the ground, there are certain difficulties in their operation and maintenance, and it is not easy to detect the problem of strand breaks in the wire during inspection and maintenance. If the problem of strand breaks in the wire is not dealt with in a timely manner, it may lead to problems such as tower collapse, pole collapse, and wire breakage, causing serious power safety accidents.

[0036] Therefore, the present invention provides an aerial repair device for repairing overhead broken-strand wires, including a mobile device and a repair binding device. When strand breaks are found in overhead wires of different voltage levels, after workers climb the tower and place the mobile device on the corresponding phase of the broken-strand wire, the mobile device sends the repair binding device to the specific position of the broken-strand wire, and the repair binding device performs aerial winding repair on the broken-strand wire to meet the operation requirements of the power grid in terms of mechanical and electrical performance. Since the repair process of the broken-strand position of the entire broken-strand wire is automatically completed in the air by using the mobile device and the repair binding device, there is no need to replace the new wire, and the traditional method of binding and winding the broken-strand wire on the ground and then re-erecting it after binding and repair is not required during the construction process. Therefore, the repair time is shortened, and the cumbersome steps such as construction wire laying, wire removal, and wire tightening are reduced, the number of power outages is reduced, the repair efficiency of the fault point is improved, and the broken-strand wire is not powered off during the repair process, and the old wire is not removed and released from the air.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0038] Figure 1 The following shows a schematic structural diagram of an aerial repair device for repairing overhead broken-strand wires provided by an embodiment of the present invention. As Figure 1 shown, the aerial repair device for repairing overhead broken-strand wires includes: a mobile device 2 and a repair binding device 3 fixed on the mobile device 2; wherein, the mobile device 2 can move along the wire under the action of power; the repair binding device 3 is used for winding and binding the broken-strand position of the broken-strand wire 1; when strand breaks are found in overhead wires of different voltage levels (such asFigure 1 After the situation of the broken-strand conductor 1) shown in the figure, after the worker climbs onto the pole tower and places the mobile device 2 on the corresponding phase of the broken-strand conductor 1, the mobile device 2 sends the repair binder 3 to the broken position of the broken-strand conductor 1, and then the repair binder 3 performs high-altitude winding repair on the broken position of the broken-strand conductor 1 to meet the operation requirements of the power grid in terms of both mechanical and electrical performance. Since the entire repair process of the broken position of the broken-strand conductor 1 is automatically completed in the air by using the mobile device 2 and the repair binder 3, there is no need to replace the new conductor, and in the construction process, there is no need to place the broken-strand conductor 1 on the ground for the traditional binding and winding repair method, and then re-erect it after the binding repair. Therefore, the maintenance time is shortened, and the cumbersome steps such as construction wire laying, wire removal, and wire tightening are reduced, the power outage times are reduced, the repair efficiency of the fault point is improved, and the broken-strand conductor 1 is not powered off during the repair process, and the old conductor is not removed and released from the air.

[0039] During the entire process of the high-altitude repair device for repairing the broken position of the overhead broken-strand conductor 1 to repair the broken position of the broken-strand conductor 1, when the mobile device 2 sends the repair binder 3 to the specific position of the broken-strand conductor 1, the mobile device 2 first needs to obtain the specific position of the break of the broken-strand conductor 1, and then it can send the repair binder 3 to the specific position of the break of the broken-strand conductor 1, and then the repair binder 3 performs binding repair on the broken-strand conductor 1. Therefore, in an embodiment of the present invention, a camera device 4 is used to obtain the specific position of the break of the broken-strand conductor 1.

[0040] Specifically, Figure 2 The figure shows a schematic structural diagram of a high-altitude repair device for repairing an overhead broken-strand conductor provided by another embodiment of the present invention. As Figure 2 shown, the high-altitude repair device for repairing an overhead broken-strand conductor further includes a camera device 4. The camera device 4 is fixed on the mobile device 2. When the mobile device 2 is manually placed on the corresponding phase of the broken-strand conductor 1, during the process of the mobile device 2 moving along the broken-strand conductor 1, the camera device 4 takes pictures of the broken-strand conductor 1. When the specific break position of the broken-strand conductor 1 is photographed, the repair binder 3 performs binding repair on the broken-strand conductor 1. Since the camera device 4 can clearly take specific pictures or video information of the broken-strand conductor 1, therefore, using the camera device 4 to obtain the specific break position of the broken-strand conductor 1 can quickly and accurately obtain the specific break position of the broken-strand conductor 1.

[0041] Among them, in order to obtain high-definition pictures or video information about the broken-strand conductor 1, the camera device 4 adopts a camera with HD 1080P or HD 960P or HD 720P, that is, the camera device 4 adopts a high-definition camera.

[0042] After the imaging device 4 captures a picture of the broken-strand conductor 1, the imaging device 4 can transmit the picture or video information to the mobile device 2. The mobile device 2 may include a picture recognition device. Then, the picture recognition device analyzes the picture transmitted by the imaging device 4. When it analyzes that the picture transmitted by the imaging device 4 is a picture of the specific position of the broken strand of the broken-strand conductor 1, the repair and binding device 3 binds and repairs the broken-strand conductor 1. The entire process of identifying the broken-strand position does not require any manual participation in identification, improving the degree of automation.

[0043] In addition, after the imaging device 4 captures a picture of the broken-strand conductor 1, the imaging device 4 can also send the picture to a display device (which can be in the hands of the staff on the ground). Then, the staff views multiple pictures captured by the imaging device 4 on the display device and then performs manual identification on the pictures to identify the specific position of the broken strand of the broken-strand conductor 1. When the staff identifies a picture of the specific position of the broken strand of the broken-strand conductor 1, the repair and binding device 3 is manually controlled by a remote controller to bind and repair the broken-strand conductor 1. That is, during the process of identifying the specific position of the broken strand of the broken-strand conductor 1, manual identification is adopted, increasing the accuracy of identification.

[0044] It should be understood that to obtain the specific position of the broken strand of the broken-strand conductor 1, the above method of collecting pictures or video information of the broken-strand conductor 1 through the imaging device 4 can be used to obtain the specific position of the broken strand of the broken-strand conductor 1. However, the present invention is not limited to the method of obtaining the specific position of the broken strand of the broken-strand conductor 1, and other methods can also be adopted to obtain the specific position of the broken strand of the broken-strand conductor 1. For example, by installing a sensor on the mobile device 2, the specific position of the broken strand of the broken-strand conductor 1 is identified through the sensor.

[0045] In another embodiment of the present invention, Figure 3 The following shows a schematic structural diagram of a high-altitude repair device for repairing an overhead broken-strand conductor provided by another embodiment of the present invention. As Figure 3 shown, the high-altitude repair device for repairing an overhead broken-strand conductor further includes: a driving motor 5, an electric control device 6, and a battery 7.

[0046] Among them, the driving motor 5 is fixed on the mobile device 2 or the repair and binding device 3. The driving motor 5 provides power for the mobile device 2 and the repair and binding device 3, so that the mobile device 2 can move along the conductor, and the repair and binding device 3 can also bind and repair the broken-strand position of the broken-strand conductor 1 under the action of power.

[0047] The electric control device 6 is electrically connected to the mobile device 2 to regulate the movement or stop of the mobile device 2, and the movement parameters of the mobile device 2 (such as the movement speed, etc.); the electric control device 6 is electrically connected to the drive motor 5 to regulate the operating parameters of the drive motor 5 (such as the rotation speed, etc.); the electric control device 6 is electrically connected to the repair bundling device 3 to control the operation or stop of the repair bundling device 3, and can also regulate the operating parameters of the repair bundling device 3, etc.; the electric control device 6 is electrically connected to the camera device 4 to regulate the operation or stop of the camera device, and can also regulate the operating parameters of the camera device 4 during operation (such as focusing to obtain a clearer picture). Due to the existence of the electric control device 6, the staff on the ground can remotely control the working process of the high-altitude repair device for repairing the overhead broken-strand conductor 1. In addition, the electric control device 6 can also autonomously and fully automatically control the operation of the mobile device 2 and the repair bundling device 3 to repair the broken-strand conductor 1, realizing full automation.

[0048] The battery 7 supplies power to the drive motor 5, the electric control device 6, and the camera device 4 so that the drive motor 5, the electric control device 6, and the camera device 4 can work normally.

[0049] In an embodiment of the present invention, as Figure 2 shown, the mobile device 2 includes: a bracket ( Figure 2 not shown in the figure) and a walker 21 fixed on the bracket. Among them, the drive motor 5 is fixed on the bracket; the walker 21 can move along the wire; among them, the drive motor 5 is used to drive the walker 21 to walk, that is, the drive motor 5 is used to drive the walker 21 to move along the broken-strand conductor 1.

[0050] Specifically, the mobile device 2 includes two walkers 21, and the walker 21 includes pulleys, that is, the mobile device 2 includes two pulleys. The pulley is the simplest walker 21, which can enable the mobile device 2 to move along the broken-strand conductor 1 and simplifies the structure of the mobile device 2.

[0051] In another embodiment of the present invention, Figure 4 The following figure shows a schematic structural diagram of a repair bundling device 3 in a high-altitude repair device for repairing an overhead broken-strand conductor provided in an embodiment of the present invention. As Figure 4As shown, the repair binder 3 includes: a winding machine outer ring 31, a roller 32, a driven wheel 33 attached to the winding machine outer ring and a binding belt 34; wherein, the winding machine outer ring 31 can make circular motion under the action of external force; the roller 32 is connected to the driving motor 5 through a transmission belt 36, and the roller 32 is rotationally connected to the winding machine outer ring 31. The driving motor 5 drives the roller 32 to rotate through the transmission belt 36, and the rotation of the roller 32 drives the winding machine outer ring 31 to rotate; the driven wheel 33 attached to the winding machine outer ring is fixed on the winding machine outer ring 31, and the rotation of the winding machine outer ring 31 drives the rotation of the driven wheel 33 attached to the winding machine outer ring; the binding belt 34 is arranged on the driven wheel 33 attached to the winding machine outer ring, and the rotation of the driven wheel 33 attached to the winding machine outer ring drives the binding belt 34 to extend.

[0052] When the high-altitude repair device for repairing broken overhead conductors is repairing the broken conductor 1, the staff first climbs the pole tower, and then places the high-altitude repair device for repairing broken overhead conductors on a phase of the broken conductor 1 at the top of the pole tower. The staff on the ground accurately locates the broken strand with the help of a camera, and then remotely starts the movement of the mobile device 2 on the conductor. When the mobile device 2 transports the winding device to the designated location of the broken conductor 1, the drive motor 5 is started. The drive motor 5 drives the roller 32 to rotate using the transmission belt 36. The rotation of the roller 32 drives the outer ring 31 of the winding machine to rotate; the rotation of the outer ring 31 of the winding machine drives the rotation of the attached driven wheel 33 of the outer ring of the winding machine; since the binding belt 34 is arranged on the attached driven wheel 33 of the outer ring of the winding machine, the binding belt 34 passes through the outer ring of the winding machine. After the ring 31 makes a circular motion, the designated binding belt 34 is fully wound around the broken strand conductor 1 that needs to be wound. At the same time, the driving motor 5 drives the mobile device 2 to move forward, and the binding belt 34 on the driven wheel 33 attached to the outer ring of the winding machine is transported to the broken strand position, and the broken strand position is repaired by binding. Then, the driving motor 5 drives the mobile device 2 to move backward, and the binding belt 34 on the driven wheel 33 attached to the outer ring of the winding machine is transported to the broken strand position, and the broken strand position is repaired by binding. This is repeated at least twice, and the binding repair of the broken strand position of the broken strand conductor 1 is completed. The mechanical properties and electrical properties of the repaired broken strand conductor 1 are the same as those of the original conductor and are not lower than all the technical parameters of the original conductor. When the repair binding device 3 completes the binding repair of the broken strand position of the broken strand conductor 1, the staff controls the mobile device 2 to return to one end of the pole tower, and then the staff takes it down and puts it back to the ground. During the entire repair process of the broken conductor 1, there is no need to shut down the power, and the old conductor does not need to be removed from the air, thereby shortening the maintenance time and reducing the tedious steps of construction such as laying out the wires, removing the wires, and tightening the wires, reducing the number of power outages, and improving the efficiency of fault point repair.

[0053] In an embodiment of the present invention, the repair banding device further includes: a banding tape fixing device, which is fixed to the mobile device and is used to fix one end of the banding tape to one end of the broken-strand conductor 1. That is, one end of the banding tape is not fixed to the broken-strand conductor 1 before repairing the broken-strand conductor 1. When the entire high-altitude repair device moves to the broken-strand conductor 1, one end of the banding tape begins to be fixed to the broken-strand conductor 1. Therefore, the banding tape fixing device can move to the position of the broken-strand conductor 1 together with the mobile device, then fix one end of the banding tape to the broken-strand conductor 1, and then the repair banding device 3 performs high-altitude winding repair on the broken position of the broken-strand conductor 1.

[0054] Specifically, in an embodiment of the present invention, Figure 5 The following shows a schematic structural diagram of a banding tape fixing device in a high-altitude repair device for repairing overhead broken-strand conductors provided by an embodiment of the present invention; as Figure 5 shown, the banding tape fixing device includes: a housing 81, the housing 81 includes an inlet 811 and an outlet 812, and the broken-strand conductor 1 and the banding tape 34 pass through the housing 81 through the inlet 811 and the outlet 812; a first electromagnet 82 and a second electromagnet 83 arranged in the housing 81, the first electromagnet 82 and the second electromagnet 83 are arranged opposite to each other; and an elastic structure 84, the elastic structure 84 is fixed between the first electromagnet 82 and the second electromagnet 83; wherein, the battery 7 supplies power to the first electromagnet 82 and the second electromagnet 83. When the first electromagnet 82 and the second electromagnet 83 are energized, they compress the elastic structure 84 so that the first electromagnet 82 and the second electromagnet 83 attract and squeeze each other, so that the first electromagnet 82 and the second electromagnet 83 fix one end of the banding tape 34 to one end of the broken-strand conductor 1. When the first electromagnet 82 and the second electromagnet 83 are de-energized, the first end electromagnet 82 and the second electromagnet 83 move away from each other under the action of the elastic structure 84, so that a ring with a certain gap is formed in the middle of the banding tape fixing device, which is convenient for passing through the damaged conductor. Since the first electromagnet and the second electromagnet have threads, when binding the broken-strand conductor 1 and the banding tape, the friction between the first electromagnet and the second electromagnet and the broken-strand conductor 1 and the banding tape is increased, and the firmness of the binding between the banding tape and the broken-strand conductor 1 is increased.

[0055] Preferably, the elastic structure 84 is a spring. The number of springs in the banding tape fixing device can be 1, or 2 or more. Therefore, the present invention does not limit the number of springs in the banding tape fixing device.

[0056] In another embodiment of the present invention, Figure 6 The following shows a schematic structural diagram of a banding tape fixing device in a high-altitude repair device for repairing overhead broken-strand conductors provided by an embodiment of the present invention; as Figure 6As shown in the figure, the binding and fixing device includes a spiral fastening outer sleeve 86 and a spiral fastening inner sleeve 87. Among them, an external thread is provided on the outer wall of the spiral fastening inner sleeve 87; the spiral fastening outer sleeve 86 includes a first end 861 and a second end 862 opposite to the first end 861, and the diameter of the first end 861 is larger than that of the second end 862; and the diameter of the first end 861 is slightly larger than the diameter of the spiral fastening inner sleeve 87. Among them, the external thread of the spiral fastening inner sleeve 87 is connected to the internal thread of the spiral fastening outer sleeve 86; the spiral fastening inner sleeve 87 rotates clockwise from the first end 861 to the second end 862 under the action of an external force, so that the spiral fastening inner sleeve 87 tightly gathers the binding band 34 and the broken-strand conductor 1 together. The diameter of the spiral fastening inner sleeve 87 is slightly smaller than the diameter of the first end 861 of the spiral fastening outer sleeve 86, so the more the spiral fastening inner sleeve 87 rotates, the tighter the binding band 34 and the broken-strand conductor 1 are. At this time, the winding device is operated for winding. After winding, the rotary fastening inner sleeve 87 rotates counterclockwise in the reverse direction and returns to its original position. At this time, there is enough space at the top of the first end 861 of the spiral fastening outer sleeve 86, and the formed gap can facilitate the passage of the wire to be wound through the damaged wire.

[0057] In another embodiment of the present invention, Figure 7 As shown in the figure, it is a schematic structural diagram of the binding band 34 in the repair binder 3 of a high-altitude repair device for repairing overhead broken-strand conductors provided by an embodiment of the present invention. As Figure 7 As shown in the figure, a protrusion 35 is provided on a surface of the binding band 34 in contact with the broken-strand conductor 1. Due to the presence of the protrusion 35, when the binding band 34 is wound around the broken-strand conductor 1, the friction between the surface of the binding band 34 in contact with the broken-strand conductor 1 and the broken-strand conductor 1 is increased, so that the binding strength between the binding band 34 and the broken-strand conductor 1 is high, and the tensile strength of the repaired conductor is improved.

[0058] Optionally, the protrusions 35 provided on a surface of the binding band 34 in contact with the broken-strand conductor 1 can be arranged in an array or arranged randomly. The present invention does not limit the arrangement manner of the protrusions 35 provided on a surface of the binding band 34 in contact with the broken-strand conductor 1.

[0059] Optionally, Figure 8 As shown in Figure 7 the sectional view of the binding band 34 along the A1-A2 section as shown in Figure 8As shown in the figure, the cross-section of the protrusion 35 provided on one surface of the binding band 34 in contact with the broken-strand conductor 1 can be triangular. It should be understood that the cross-section of the protrusion 35 provided on one surface of the binding band 34 in contact with the broken-strand conductor 1 can also be other shapes, such as semi-circular, trapezoidal, polygonal, a shape combining a straight line and a curve, etc. Therefore, the specific shape of the cross-section of the protrusion 35 provided on one surface of the binding band 34 in contact with the broken-strand conductor 1 is not limited in the embodiments of the present invention.

[0060] Specifically, Figure 9 As shown in the figure, it is a schematic structural diagram of the binding band 34 in the repair binder 3 in a high-altitude repair device for repairing an overhead broken-strand conductor provided by another embodiment of the present invention. Figure 9 As shown in the figure, a stripe protrusion 35 is provided on one surface of the binding band 34 in contact with the broken-strand conductor 1, that is, the protrusion 35 provided on one surface of the binding band 34 in contact with the broken-strand conductor 1 is a stripe protrusion 35, and two adjacent stripe protrusions 35 are parallel to each other. The stripe protrusion 35 can not only increase the friction force between the surface of the binding band 34 in contact with the broken-strand conductor 1 and the broken-strand conductor 1, but also has a simple process for preparing the stripe protrusion 35.

[0061] Optionally, as Figure 9 shown, the extending direction of the stripe protrusion 35 is perpendicular to the extending direction of the conductor. When the binding band 34 is wound around the broken-strand conductor 1, since the extending direction of the stripe protrusion 35 is perpendicular to the extending direction of the conductor, the friction force between the surface of the binding band 34 in contact with the broken-strand conductor 1 and the broken-strand conductor 1 is further increased, so that the binding strength between the binding band 34 and the broken-strand conductor 1 is large, and the tensile strength of the repaired conductor is further improved.

[0062] It should be understood that when a stripe protrusion 35 is provided on one surface of the binding band 34 in contact with the broken-strand conductor 1, two adjacent stripe protrusions 35 can be parallel, as Figure 9 shown; they can also be non-parallel, such as cross-shaped. When two adjacent stripe protrusions 35 are parallel, the stripe protrusion 35 can be linear, as Figure 9 shown; it can also be curved.

[0063] Optionally, the cross-section of the stripe protrusion 35 provided on one surface of the binding band 34 in contact with the broken-strand conductor 1 can be semi-circular. It should be understood that the cross-section of the stripe protrusion 35 provided on one surface of the binding band 34 in contact with the broken-strand conductor 1 can also be other shapes, such as triangular, trapezoidal, polygonal, a shape combining a straight line and a curve, etc. Therefore, the specific shape of the cross-section of the stripe protrusion 35 provided on one surface of the binding band 34 in contact with the broken-strand conductor 1 is not limited in the embodiments of the present invention.

[0064] In an embodiment of the present invention, Figure 10The following is a schematic assembly structure diagram between the binding belt 34 in the repair binder 3 of a high-altitude repair device for repairing overhead broken-strand conductors provided by another embodiment of the present invention and the broken-strand conductor 1, as Figure 10 shown, the included angle α between the broken-strand conductor 1 and the binding belt 34 is 30°, so that it can be consistent with the original lay direction of the broken-strand conductor 1, which can make the broken-strand conductor 1 fit more closely with the binding belt 34. When the broken-strand conductor 1 is partially wrapped by the binding belt 34, then use the control mobile device 2 to make the mobile device 2 move in the reverse direction back to the origin. At this time, the direction of the binding belt 34 is consistent with that of the conductor, so that the old conductor can be completely wrapped, thus solving the problem that the binding belt 34 in the prior art cannot completely wrap the old conductor. In addition, the entire binding belt 34 extends from the outer ring auxiliary driven wheel 33 of the winding machine and winds around the broken-strand conductor, and the winding effect of the binding belt 34 is highly tight. The old broken-strand conductor 1 after being processed by winding truly meets the mechanical properties and electrical properties. The mechanical properties and electrical properties of the broken-strand conductor are the same as those of the original conductor and are not lower than all technical parameters of the original conductor.

[0065] In an embodiment of the present invention, when the broken-strand conductor 1 is an insulated conductor, the material of the binding belt 34 includes copper; when the broken-strand conductor 1 includes a steel-cored aluminum stranded wire, the material of the binding belt 34 includes aluminum alloy.

[0066] During the process of binding and repairing the broken-strand position of the broken-strand conductor 1 by the above-mentioned high-altitude repair device for repairing overhead broken-strand conductors, for the sake of safety, two people are required to operate. One operates on the ground, and the other person needs to climb onto the pole tower and place the high-altitude repair device for repairing overhead broken-strand conductors on one phase of the broken-strand conductor 1.

[0067] In addition, for the convenience of assembly and portability, the mobile device 2, the repair binder 3, and the camera device 4 of the above-mentioned high-altitude repair device for repairing overhead broken-strand conductors are independently arranged in a box, and the mobile device 2, the repair binder 3, and the camera device 4 are assembled when in use.

[0068] It should be understood that the high-altitude repair device for repairing overhead broken-strand conductors provided by the embodiments of the present invention can not only repair the conductors for power transmission. It can also be applied to overhead line equipment, communication lines, cable and other line equipment that require splicing in communication and other fields. It not only solves the technical problems in places where the old conductors are not replaced in time or the replacement is difficult. At the same time, it reduces the cost of re-erecting new conductors, saving nearly one million yuan for the power supply company in this regard every year, and its economic benefits are quite remarkable.

[0069] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
