Description

Technical Field

[0001] This invention relates to the field of insulated conductor technology, and more specifically to a high-strength overhead insulated conductor. Background Technology

[0002] As an important carrier of power transmission, the mechanical strength and electrical reliability of overhead insulated conductors directly affect the safe and stable operation of the power grid. Traditional overhead insulated conductors usually adopt internal reinforcement structures (such as metal reinforcing cores or composite reinforcing layers) to improve tensile strength. However, during long-term operation, due to factors such as environmental stress, material fatigue and external forces, the internal reinforcing components may suffer local damage or even breakage. Such damage is often located inside the insulation layer and is difficult to observe directly from the outside, making it difficult to detect defects in time. This may lead to a decline in the mechanical properties of the conductor, an increase in sag, or even serious accidents such as wire breakage.

[0003] Currently, the inspection of overhead conductors mostly relies on regular manual inspections or fixed monitoring equipment, which has problems such as low efficiency and inability to locate damage in real time. Although some technologies have attempted to monitor online through changes in electrical parameters, there is still a lack of integrated inspection methods that can move along the conductor, autonomously identify the location of defects, and mark them intuitively. Summary of the Invention

A connecting rod is fixedly mounted at the end of the plug away from the connecting ring plate. An arc-shaped connecting ring is fixedly mounted at the end of each connecting rod away from the connecting ring plate. A connecting seat is evenly fixedly mounted on one side of the arc-shaped connecting ring.

[0014] Preferably, an arc-shaped groove is formed inside the arc-shaped connecting ring and below the connecting seat. A first connecting frame is slidably installed in the arc-shaped groove. A counterweight is rotatably installed on the inner wall of the first connecting frame. A limiting mounting frame is fixedly installed between the connecting rods and above the counterweight. The limiting mounting frame is fixedly connected to the marking can and the detection element respectively. A rotary drive is fixedly installed at the upper end of the marking can. The output end of the rotary drive passes through the marking can and is connected to the threaded sleeve. The rotary drive, the detection element, and the controller are electrically connected.

[0015] Preferably, a lifting plate is slidably installed inside the marking can, a screw sleeve is rotatably installed at the inner top of the marking can, a screw rod is threaded on the inner wall of the screw sleeve, the lower end of the screw rod is rotatably connected to the lifting plate, a plug is slidably installed on the outer wall of the marking can below the lifting plate, and a nozzle is embedded at the lower end of the marking can.

[0018] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0019] First, by setting conductive reinforcing strips and equidistantly distributed contact rings inside the conductor body, and designing an integrated detection device that can move along the outer wall of the conductor, the detection rings supply power to the reinforcing strips, and the voltage change at the contact point is monitored in real time by a window comparator. This enables online and mobile electrical detection of damage to the internal reinforcing components of the conductor. When a fracture defect is detected, the controller immediately drives the marking tank to spray marking liquid to make a visual mark on the corresponding position on the outer surface of the conductor, thereby marking the damage. This enables autonomous inspection, precise positioning and instant marking of hidden defects in overhead insulated conductors, greatly improving detection efficiency and the intuitiveness of defect management.

[0020] Secondly, by setting up a flexible connecting assembly consisting of a rotating retaining ring, corrugated sections, and springs, the device can move smoothly according to the curvature of the conductor, avoiding jamming. The moving assembly adopts a roller contact structure with spring buffer and adds a counterweight to ensure the stability and reliable fit of the device when moving in different sections of the overhead conductor (especially the sag section). The detection assembly, through the cooperation of the rotating frame and the elastic connecting rope, enables the detection ring to adapt to the surface of the conductor and maintain good electrical contact. These mechanical structural designs together improve the device's passability, movement stability, and detection reliability in complex overhead environments, ensuring smooth and accurate long-term inspection operations.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] The present invention will be further described below with reference to embodiments.

[0031] Example: Refer to Figures 1 to 6 A high-strength overhead insulated conductor, comprising:

[0032] The conductor body 1 has a battery cell 101 fixedly installed inside it. The conductor body 1 has a circumferential array of conductive reinforcing strips 102 embedded inside it. The conductive reinforcing strips 102 are made of high-strength copper alloy or aluminum-magnesium alloy. The outer wall of the conductive reinforcing strips 102 and the conductor body 1 have contact rings 103 installed at equal intervals.

[0033] The connecting component 2 includes two sets of rotating retaining rings 201 sleeved on the outer wall of the conductor body 1. A corrugated section 202 is fixedly installed between each set of rotating retaining rings 201. A window comparator is fixedly installed inside the rotating retaining rings 201. The rotating retaining rings 201 and the corrugated section 202 of the connecting component 2 cooperate to enable the device to smoothly pass through the bending of the overhead conductor.

[0034] The moving component marker 3 is used to drive the connecting component 2 to move on the outer wall of the conductor body 1. The moving component marker 3 includes a marker can 313 and a detection element 314 symmetrically arranged on both sides of the connecting component 2. The core function of the detection element 314 is to identify the marking color sprayed by the marking can 313 on the surface of the conductor body 1, and then determine whether there is a marked historical defect at that location. During the movement of the device, the detection element 314 uses an existing device such as a photoelectric color sensor to continuously scan the outer wall of the conductor. When a preset marking color is identified, it sends a signal to the controller. The controller determines that the location is a known defect point and counts and records it.

[0035] The marking can 313 is used to mark defective sections of the conductor body 1;

[0036] Detection component 4 includes detection rings 406 symmetrically arranged on both sides of connection component 2 and located away from marking can 313 and detection element 314. Detection rings 406 are slidably connected to the outer wall of conductor body 1. Detection rings 406 are electrically connected to a controller, which can be implemented using an existing microcontroller (such as a single-chip microcomputer) or programmable logic controller (PLC). Its working process is as follows: when the window comparator detects an abnormal voltage at point B of conductive reinforcement strip 102, it sends a trigger signal to the controller, which then drives the rotary drive to work, causing marking can 313 to spray... The marking liquid is used to locate defects. At the same time, the controller continuously receives signals from the detection element 314, and uses a preset color recognition and delay filtering algorithm to determine whether there are new markings on the surface of the conductor. It counts and stores the confirmed defect marking points, and supplies power to the conductive reinforcement strip 102 through the controller. The conductive reinforcement strip 102 in the conductor body 1 is embedded in a circumferential array, which not only enhances the overall tensile strength of the conductor, but also reduces the risk of conductor deformation during construction. The equidistantly distributed contact rings 103 design enables the detection device to be accurately connected, simplifying the on-site installation process.

[0037] Reference Figure 3 Two sets of rotating retaining rings 201 are rotatably connected. A first retaining connector 203 is fixedly installed between the rotating retaining rings 201 at a position away from the rotation point. A connecting ring plate 205 is fixedly installed on the opposite side of the two sets of rotating retaining rings 201. A first external block 204 is fixedly installed in a circumferential array on the outer wall of the connecting ring plate 205. A first spring 207 is fixedly installed between the first external blocks 204.

[0038] Reference Figure 4 A mounting hole 206 is provided in a circumferential array on one side of the connecting ring plate 205. A plug 301 is slidably mounted in the mounting hole 206. A connecting rod 302 is fixedly mounted on the end of the plug 301 away from the connecting ring plate 205. An arc-shaped connecting ring 303 is fixedly mounted on the end of each connecting rod 302 away from the connecting ring plate 205. A connecting seat 304 is evenly fixedly mounted on one side of the arc-shaped connecting ring 303. A telescopic rod 308 is slidably mounted on the end of the connecting seat 304 near the axis of the connecting ring plate 205. A straight rod 305 is fixedly mounted on the end of the telescopic rod 308 near the axis of the connecting ring plate 205. A roller 307 is rotatably mounted on the end of the straight rod 305 near the axis of the connecting ring plate 205. A second spring 306 is fixedly mounted between the connecting seat 304 and the straight rod 305 and on the outer wall of the telescopic rod 308.

[0039] Reference Figure 4 An arc-shaped groove 309 is formed inside the arc-shaped connecting ring 303 and below the connecting seat 304. A first connecting frame 310 is slidably installed in the arc-shaped groove 309. A counterweight 311 is rotatably installed on the inner wall of the first connecting frame 310. A limiting mounting bracket 312 is fixedly installed between the connecting rods 302 and above the counterweight 311. The limiting mounting bracket 312 is installed on the connecting rods 302 by existing screws, so that the arc-shaped connecting ring 303 forms an integral closed structure. The limiting mounting bracket 312 is connected to the marking tank 313 and the detection element respectively. 314 is fixedly connected. A rotary drive is fixedly installed on the upper end of the marking tank 313. The rotary drive can be implemented by an existing micro stepper motor or servo motor. Its output shaft is directly connected to the screw sleeve 315 or through a coupling. The controller can precisely control the downward stroke of the screw 316 and the amount of marking liquid sprayed by adjusting the rotation angle and speed of the motor, so as to ensure the accuracy and reliability of the marking action. The output end of the rotary drive passes through the marking tank 313 and is electrically connected to the screw sleeve 315, the rotary drive, the detection element 314 and the controller.

[0040] Reference Figure 4 A lifting plate 317 is airtightly and slidably installed inside the marking can 313. A screw sleeve 315 is rotatably installed on the inner top of the marking can 313. A screw rod 316 is threaded on the inner wall of the screw sleeve 315. The lower end of the screw rod 316 is rotatably connected to the lifting plate 317. A plug 318 is slidably installed on the outer wall of the marking can 313 below the lifting plate 317. A nozzle 319 is embedded at the lower end of the marking can 313.

[0041] Reference Figures 5 to 6A second outer plate 401 is fixedly installed on the outer wall of the connecting ring plate 205 in a circumferential array. A long rod 402 is fixedly installed on one side of the second outer plate 401. A rotating frame 403 is rotatably installed on one end of the long rod 402. An elastic connecting rope 404 is fixedly installed on one side of the second outer plate 401. One end of the elastic connecting rope 404 passes through the long rod 402 and the rotating frame 403 and is fixedly connected to the inner wall of the rotating frame 403 at a position away from the long rod 402.

[0042] Reference Figures 5 to 6 A second connecting frame 405 is fixedly installed between the rotating frames 403. The second connecting frame 405 is fixedly connected to the detection ring 406 by existing screws. The second connecting frame 405 is fixedly connected to the detection ring 406. The detection rings 406 are rotatably connected. A second snap-fit ​​connector 407 is fixedly installed between the detection rings 406 and away from the rotation point.

[0043] The working principle of this invention is as follows:

[0044] A conductive reinforcing strip 102 is provided inside the conductor body 1. The conductive reinforcing strip 102 can be embedded in the conductor body 1 or embedded in the outer wall of the conductor body 1. The conductive reinforcing strip 102 can support the conductor body 1 and the battery cell 101 to improve their overall strength. Figure 2 For example, each conductive reinforcing strip 102 is provided with three contact rings 103, which are points A, B and C respectively. The detection rings 406 are points D and F respectively, and the window comparator is point E. Point D corresponds to point A, point E corresponds to point B, and point F corresponds to point C. Points A, B and C are considered as small detection segments, and the detection ends of each small segment are respectively set on a whole conductor body 1.

[0045] When the detection device moves along the conductor, points D and F on the two detection rings 406 contact points A and C of the contact ring 103 respectively, and the probe at point E of the window comparator contacts point B of the contact ring 103. The external power supply supplies power to the conductive reinforcement strip 102 through the detection rings 406. Current flows in from points D and A and flows out from points F and C.

[0046] Under normal testing conditions, when the conductive reinforcement strip 102 is intact, the current flows from point A through the conductive reinforcement strip 102 to point C. Point B serves as an intermediate point, and its voltage value is within the preset normal range. The window comparator detects that the voltage at point B is within the normal window range, determines that the conductive reinforcement strip 102 is normal, and does not trigger the marking action.

[0047] When the conductive reinforcing strip 102 breaks, if the break occurs between segments A and B, the voltage at point B approaches the voltage at point C; if the break occurs between segments B and C, the voltage at point B approaches the voltage at point A. The window comparator detects that the voltage at point B exceeds the preset normal window range, and the comparator outputs an abnormal signal, triggering a marking action.

[0048] When an anomaly is detected, the window comparator sends a trigger signal to the controller. The controller controls the rotary drive unit set on the marking tank 313. The rotary drive unit drives the screw sleeve 315 to rotate the screw 316, so that the screw 316 drives the lifting plate 317 to move downward, squeezing the marking liquid in the marking tank 313. The marking liquid is sprayed out from the nozzle 319. The marking liquid in the marking tank 313 is pre-filled with a specific color of marking liquid, and different colors can be used for marking and distinguishing different inspection times and different numbers of inspections. The marking liquid adheres to the outer wall of the small section inspection end, clearly indicating that the section has a defect, which is convenient for subsequent personnel to inspect. Pulling out the plug 318 can add marking pigment into the marking tank 313.

[0049] The detection element 314, such as a photoelectric color sensor, is installed on the moving component marker 3 and symmetrically arranged with the marker tank 313. Its probe always points to the outer wall of the conductor. During the movement of the device along the outer wall of the conductor body 1, the detection element 314 continuously scans the surface of the conductor in front. When it detects an unmarked surface of the conductor body 1, the sensor outputs a signal, and the controller determines that "no new marker is added". The counter set in the controller remains unchanged. When the sensor moves to the section that has been sprayed with marking liquid, the color of the surface of the conductor body 1 changes, and the spectral characteristics of the reflection change accordingly. The detection element 314 will immediately capture this change and identify it as a preset "marking color" signal.

[0050] The controller is pre-programmed with color recognition and counting logic. The controller has a short delay judgment with a delay signal of 50 milliseconds to filter out instantaneous interference signals caused by dirt, reflection and other factors on the surface of the conductor body 1, so as to ensure that only continuous and stable color changes are confirmed. Once the detection element 314 confirms that a valid mark color signal is identified, the controller determines it as a new defect mark point. At this time, the counter inside the controller starts counting.

[0051] It is important to note that there are two detection rings 406, and the window comparator is located in the middle of the detection ring 406. There are many possible arrangements of points D, E, and F that are in contact with points A, B, and C. When points D, E, and F coincide with one of the sets of points A, B, and C before moving, points D, E, and F may coincide with points B, C, and A, or points C, A, and B, or points A, B, and C. If points D, E, and F are in contact with... The correspondence between points A, B, and C is random. Therefore, the "window comparator" detection method based on voltage changes at point B (the intermediate point) will not work reliably. This is because the detection logic relies on a fixed power supply-monitoring-return point relationship (power supply A—monitoring B—return C). Once this relationship is disrupted due to movement, the meaning of the voltage change becomes uncertain, potentially leading to an alarm when no break is detected or when there is no break. Therefore, different, easily distinguishable electrical parameters need to be designed for points A, B, and C.

[0052] For example, there is a small but precise preset resistance difference between the three contact rings 103 at points A, B, and C and the main body of the conductor 1. For example, the resistance at point A is R, at point B it is 2R, and at point C it is 3R. A miniature capacitor with a different capacitance value is connected in parallel to each contact ring so that it has a specific resonant frequency or impedance phase characteristics.

[0053] Each time the controller stops or moves to a new position, it first applies a test signal, such as a small current or a specific frequency AC signal, to the contact point through the detection loop 406 and measures the response. By analyzing the response signal, such as the measured resistance value, resonant frequency, or decoded digital ID, it can automatically identify whether the three points currently in contact are arranged as "point A, point B, point C", "point B, point C, point A", or "point C, point A, point B", etc.

[0054] After identifying the current contact correspondence, the controller will dynamically switch its internal detection algorithm. For example, if it is identified as [point D-point A, point E-point B, point F-point C], the original logic will be executed: monitor the voltage of point E (corresponding to point B). If it is identified as [point D-point B, point E-point C, point F-point A], the system will automatically identify the current point E as point C and execute the detection logic for the new topology of "the monitoring point is located between the power supply point and the return point", and recalculate the expected normal voltage window.

[0055] First, the rotating retaining ring 201 is rotated open and fitted onto the outer wall of the conductor body 1. By pressing the first retaining connector 203, the rotating retaining ring 201 is fitted onto the outer wall of the conductor body 1. At this time, the corrugated section 202 and the connecting ring plate 205 are simultaneously fitted onto the outer wall of the conductor body 1. The corrugated section 202 allows the connecting component 2, the moving component marking 3, and the detection component 4 to bend in accordance with the curvature of the conductor body 1 when they move on the outer wall of the conductor body 1. The first spring 207 set between the first outer blocks 204 can elastically compensate for the bending between the rotating retaining rings 201, facilitating the bending and reset of the corrugated section 202 and the support force between the rotating retaining rings 201, and preventing the connecting component 2 and the moving component marking 3 from bending. 3. When the detection component 4 moves and gets stuck, the upper opening of the arc-shaped connecting ring 303 is engaged with the outer wall of the conductor body 1, so that the roller 307 rolls and contacts the outer wall of the conductor body 1. Then, the plug 301 is installed in the mounting hole 206 on one side of the connecting ring plate 205, so that the moving component mark 3 is supported on both sides of the connecting component 2. The straight rod 305 will slide on the outer wall of the telescopic rod 308. When the conductor is raised in the air, due to gravity and the flexibility of the cable, the cable will bend downward with a certain arc. Therefore, the straight rod 305 can drive the telescopic rod 308 to slide towards the inner wall of the connecting seat 304 and compress the second spring 306, so that the roller 307 is in contact with and supported on the outer wall of the conductor body 1 for movement.

[0056] It should be noted that when driving this device to move, the main conductor 1 is usually erected in the air by a tower. A cable is set according to the distance between the towers, and the two ends of the cable are fixed together to form an elliptical shape. The two ends are rotated on the towers respectively, so that the cable is parallel between the towers. The lower cable is connected to this device, and the upper cable is pulled at a constant speed (or an existing motor bearing can be used to drive the cable to move at a constant speed). This will drive the device to move on the outer wall of the main conductor 1, which is equivalent to the movement of a conveyor belt. When testing multiple main conductors 1 between towers, the device is switched to another main conductor 1 at the end point of testing one main conductor 1, and the cable is pulled back and forth to move and perform the test.

[0057] The detection ring 406 is fitted onto the outer wall of the conductor body 1, and then the second snap connector 407 is pressed to fix it. The detection ring 406 is installed between the second connecting frames 405 using the existing screws. It should be noted that when moving, the rotatable connection between the rotating frame 403 and the long rod 402 allows the detection ring 406 to move in accordance with the curvature of the outer wall of the conductor body 1. When the rotating frame 403 and the long rod 402 rotate, the elastic connecting rope 404 can be stretched and maintain a certain elasticity, so that the rotating frame 403 and the long rod 402 can return to a horizontal state after passing through the bending section.

[0058] The first connecting frame 310, which is slidably set in the arc groove 309, can drive the stability of the entire connecting assembly 2 and the moving assembly mark 3 when they move on the outer wall of the conductor body 1. The weight of the counterweight 311 can keep the mark can 313 in an upward position, so that the entire device moves on the outer wall of the conductor body 1 in a stable position.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
