Description

Technical Field

[0001] This invention relates to the field of power facility testing technology, and in particular to a cable fault detection device and its testing method. Background Technology

[0002] Cables may experience faults such as short circuits, open circuits, and insulation aging during long-term use, which can lead to power transmission interruptions, voltage fluctuations, current leakage, and power loss. Regular cable inspections are necessary to ensure normal cable operation.

[0003] When inspecting the surface of cables at high altitudes, the inspection device is usually placed on the cable surface and then moved. However, high-altitude power lines are generally composed of multiple cables, and the inspection process requires changing the inspection device. Existing inspection devices can only be moved and inspected on a single cable. When changing cables, the inspection device needs to be manually removed from the current cable and installed on another cable, which increases the difficulty of operation, increases the risk, and reduces the inspection efficiency. Summary of the Invention

[0004] The main objective of this invention is to provide a cable fault detection device and its detection method, aiming to solve existing technical problems.

[0005] To achieve the above objectives, the present invention provides a cable fault detection device, comprising: The housing has a wire clamping assembly for moving along the cable line and a detection assembly for detecting cable surface faults at its bottom. A suspension plate is provided above the housing, and the suspension plate is connected to the housing by a telescopic mechanism. A wire changing frame includes a fixing plate, with hanging rods at both ends of the fixing plate. The ends of the hanging rods are connected to wire changing rods located at both ends of the housing, and the ends of the wire changing rods are provided with wiring assemblies. The connecting arm has one end fixedly connected to the suspension plate and the other end movably connected to the fixed plate through a connecting mechanism.

[0006] Furthermore, the line-changing rod includes an intermediate rod, one end of which is rotatably connected to a first end rod, and the other end of which is rotatably connected to a second end rod. Both the end of the first end rod and the end of the intermediate rod are provided with a driving mechanism.

[0007] Furthermore, the intermediate rod is a bidirectional telescopic structure used to adjust the length of the line-changing rod.

[0008] Furthermore, the connecting mechanism includes a slider embedded in the connecting arm, a rotating shaft passing through the slider, one end of the rotating shaft being connected to a rotating mechanism on the fixed plate, and the other end being connected to a telescopic shaft, the end of the telescopic shaft being connected to a toothed plate, and the connecting arm having a toothed groove that mates with the toothed plate, and when the toothed plate mates with the toothed groove, the rotating mechanism can drive the connecting arm to rotate.

[0009] Furthermore, the connecting arm has a waist-shaped hole, the slider slides in the waist-shaped hole, and the waist-shaped hole is provided with a first linear mechanism for controlling the movement of the slider.

[0010] Furthermore, it also includes first air holes opened on both sides of the housing, a first air duct communicating with the first air holes inside the housing, second air holes at both ends of the housing, a second air duct communicating with the second air holes inside the housing, and both the first air duct and the second air duct are supplied with air by a fan.

[0011] Furthermore, both the first and second air vents are equipped with motorized blades, and both the first and second air ducts are equipped with valves.

[0012] Furthermore, the wiring assembly includes a support rod with wire clamping wheels at both ends. The two wire clamping wheels are connected by a clamping cylinder. The end of the support rod is provided with a vertical guide rail, and a movable lifting rod is provided on the vertical guide rail.

[0013] Furthermore, the detection component includes a movable seat slidably disposed on the housing, the movable seat being controlled to move on the housing by a second linear mechanism, and the movable seat being provided with a slidingly engaged arc-shaped plate, the side wall of the arc-shaped plate being provided with an arc-shaped toothed plate, the arc-shaped toothed plate being meshed with a drive gear, and the surface of the arc-shaped plate being provided with a detection unit.

[0014] A cable fault detection method, employing the cable fault detection device described above, includes the following steps; The housing is placed on the cable to be tested and fixed to the cable to be tested by the clamping assembly. The wiring assemblies at both ends of the cable changing rod are connected to the cable to be tested and another cable adjacent to the cable to be tested, respectively. The clamping assembly is controlled to drive the housing to move along the cable, and during the process, the detection assembly detects faults on the surface of the cable. After the current cable is inspected, the connecting arm is rotated to move the housing from the current cable to another cable for inspection.

[0015] The beneficial effects of this invention are reflected in: This invention, through the cooperation of the cable changer and the connecting arm, enables the detection components carried by the housing to control the housing to cross over to another cable after the detection of one cable has been completed, without human intervention, reducing the difficulty and danger of operation, and improving detection efficiency.

[0016] By setting up a line-changing rod, the two ends of the line-changing rod contact the two cables when the detection component moves along the cable for detection. This can improve the stability of the housing during movement and reduce the impact of high-altitude winds on the overall detection device.

[0017] This invention enables the housing to perform cable replacement operations not only between cables of the same height, but also between cables of different heights, through the rotatable connection between the intermediate rod and the end rod.

[0018] This invention features air vents around the perimeter of the housing, allowing air to escape through different vents. The side vents can mitigate some of the impact of high-altitude winds on the overall detection device, while the end vents can clear foreign objects from the cable in advance, ensuring efficient operation of the detection device.

Detailed Implementation

[0021] 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 a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-9 This invention provides a cable fault detection device, including a housing 100. The bottom of the housing 100 is provided with a clamping assembly 110 for moving along the cable line and a detection assembly 120 for detecting surface faults in the cable. A suspension plate 101 is provided above the housing 100, and the suspension plate 101 is connected to the housing 100 via a telescopic mechanism 102; specifically, the telescopic mechanism 102 can be an electric telescopic rod. Specifically, the clamping assembly 110 includes four friction wheels symmetrically distributed at the bottom of the housing 100. Each pair of friction wheels is controlled by a cylinder to move closer or further apart, thereby clamping and fixing the cable. The friction wheels are controlled by a motor to rotate, enabling them to move along the cable.

[0023] The wire changing frame 200 includes a fixing plate 201, and the fixing plate 201 has hanging rods 202 at both ends. Specifically, the hanging rods are telescopic rod structures. The ends of the hanging rods 202 are connected to the wire changing rods 203 located at both ends of the housing 100. The wire changing rods 203 have wiring assemblies 204 at both ends. The connecting arm 300 has one end fixedly connected to the suspension plate 101, and the other end movably connected to the fixed plate 201 through the connecting mechanism 310.

[0024] In this embodiment, the housing 100 is placed on the cable to be tested and fixed to the cable to be tested by the clamping assembly 110. The wiring assemblies 204 at both ends of the cable changing rod 203 are connected to the cable to be tested and another cable adjacent to the cable to be tested, respectively. The clamping assembly 110 is controlled to drive the housing 100 to move along the cable. During the process, the detection assembly 120 detects the faults on the surface of the cable. After the current cable is tested, the connecting arm 300 is driven to rotate, so that the housing 100 can move from the current cable to another cable to perform the testing operation.

[0025] In this embodiment, through the cooperation of the cable changer 200 and the connecting arm 300, the detection component 120 carried by the housing 100 can control the housing 100 to cross over to another cable after completing the detection of one cable, without human intervention, reducing the difficulty and danger of operation, and improving the detection efficiency.

[0026] In this embodiment, the line-changing rod 203 includes an intermediate rod 2031. One end of the intermediate rod 2031 is rotatably connected to a first end rod 2032, and the other end is rotatably connected to a second end rod 2033. Both the end of the first end rod 2032 and the end of the intermediate rod 2031 are provided with driving mechanisms. Specifically, the driving mechanism at the end of the first end rod 2032 is used to control the rotation of the intermediate rod 2031, and the driving mechanism at the end of the intermediate rod 2031 is used to control the rotation of the second end rod 2033; wherein, the driving mechanism can be a rotary motor.

[0027] In this embodiment, when multiple cables to be tested are at the same height, the intermediate rod 2031, the first end rod 2032, and the second end rod 2033 are on the same straight line. At this time, controlling the rotation of the connecting arm 300 can drive the housing 100 to cross from the current cable to another cable for testing. When multiple cables to be tested are at different heights, the intermediate rod 2031 and the second end rod 2033 are rotated by the drive mechanism, so that the intermediate rod 2031 is tilted at an angle equal to the tilt angle between the two cables at different heights. The first end rod 2032 and the second end rod 2033 are kept in a horizontal state, ensuring that the terminal assembly 204 connected at the end contacts the cable in a horizontal posture. This ensures the stability of the housing 100 during movement. At the same time, it can cooperate with the rotation of the connecting arm 300 to move the housing 100 from the cable at the current height to the cable at another height for cable switching, realizing the cable crossing testing operation between different heights.

[0028] In this embodiment, the intermediate rod 2031 is a bidirectional telescopic structure used to adjust the length of the line-changing rod 203. Specifically, the intermediate rod 2031 includes a sleeve, and electric actuators are provided at both ends of the sleeve.

[0029] In this embodiment, when testing cables, the length of the entire cable-changing rod 203 is adjusted by the intermediate rod 2031 according to the distance between two adjacent cables. This ensures that the wiring assembly 204 connected to the ends of the first end rod 2032 and the second end rod 2033 can maintain effective contact with the cable, thereby enabling the testing device to adapt to cable-changing testing operations with different intervals.

[0030] In this embodiment, the connecting mechanism 310 includes a slider 311 embedded in the connecting arm 300. A rotating shaft 312 passes through the slider 311. One end of the rotating shaft 312 is connected to a rotating mechanism 313 mounted on the fixed plate 201, and the other end is connected to a telescopic shaft 314. A toothed plate 315 is connected to the end of the telescopic shaft 314. The connecting arm 300 has a toothed groove 303 that mates with the toothed plate 315. When the toothed plate 315 mates with the toothed groove 303, the rotating mechanism 313 can drive the connecting arm 300 to rotate. Specifically, the toothed groove 303 is provided at both ends of the connecting arm 300. Specifically, the rotating mechanism 313 can be a motor.

[0031] In this embodiment, after the detection component 120 completes the detection of the current cable, the connecting arm 300 is rotated by the rotating mechanism 313, which drives the housing 100 to cross over from the current cable to the adjacent cable. At this time, the toothed plate 315 and the toothed groove 303 are in a docking state, that is, the slider 311 is in a locked state, realizing the rapid reversal detection of the detection component 120, reducing the difficulty of operation and improving the detection efficiency.

[0032] In this embodiment, the connecting arm 300 has a waist-shaped hole 301, the slider 311 slides in the waist-shaped hole 301, and a first linear mechanism 302 for controlling the movement of the slider 311 is provided in the waist-shaped hole 301. Specifically, the first linear mechanism 302 can be an electric actuator.

[0033] In this embodiment, a typical high-altitude power line typically includes at least three cables. For ease of understanding, we will use three cables as an example, specifically a first cable, a second cable, and a third cable arranged sequentially. When testing begins, the wiring assemblies 204 at both ends of the line-changing rod 203 contact the first and second cables respectively. Driven by the clamping assembly 110, the housing 100 moves along the cable through the detection assembly 120 for testing. After the first cable is tested, the housing 100 is rotated via the rotating mechanism 313. At this time, the toothed plate 315 and the toothed groove 303 are in a mating state, causing the housing 100 to move from the first cable to the second cable. Subsequently, the... The second cable is inspected. After the inspection of the second cable is completed, the toothed plate 315 is moved by the telescopic shaft 314, so that the toothed plate 315 is disengaged from the tooth groove 303. At this time, the slider 311 is in the unlocked state. Then, the first linear mechanism 302 is controlled to move the slider 311 along the waist-shaped hole 301, so that the fixing plate 201 moves the wire changing rods 203 on both sides from between the first cable and the second cable to between the second cable and the third cable. Then, the telescopic shaft 314 is controlled to push the toothed plate 315 to connect with the tooth groove. Finally, the connecting arm 300 is controlled to rotate, so that the housing 100 is moved from the second cable to the third cable, and then the third cable is inspected.

[0034] In this embodiment, the system also includes first air vents 1001 formed on both side walls of the housing 100, a first air duct 1002 communicating with the first air vents 1001 within the housing 100, second air vents 1003 at both ends of the housing 100, and a second air duct 1004 communicating with the second air vents 1003 within the housing 100. Both the first air duct 1002 and the second air duct 1004 are ventilated by a fan. Specifically, the wind direction and speed can be monitored using existing sensors to assist operators in making judgments.

[0035] In this embodiment, when the housing 100 is exposed to side wind, the first vent 1001 on the side facing away from the wind can be controlled to release air, providing a counterforce to offset part of the side wind's impact on the housing 100 and improve the stability of the housing 100 in windy conditions. When encountering rain or snow, the second vent 1003 can be controlled to release air, which can blow away the snow on the cable, making it easier for the housing 100 to move along the cable for detection.

[0036] In this embodiment, electric blades are provided in both the first air hole 1001 and the second air hole 1003, and valves are provided in both the first air duct 1002 and the second air duct 1004.

[0037] In this embodiment, the electric blades facilitate guiding the airflow direction output from the duct, allowing for adjustment of the airflow direction as needed to meet different requirements. The valves facilitate controlling the airflow from the first duct 1002 or the second duct 1004 as needed, preventing excess airflow from overflowing.

[0038] In this embodiment, the wiring assembly 204 includes a support rod 2041, with wire clamping wheels 2042 at both ends of the support rod 2041. The two wire clamping wheels 2042 are connected by a clamping cylinder 2043. A vertical guide rail 2044 is provided at the end of the support rod 2041, and a movable lifting rod 2045 is provided on the vertical guide rail 2044.

[0039] In this embodiment, after the housing 100 is placed on the cable, the wiring assemblies 204 at both ends of the cable changing rod 203 are moved to the two adjacent cables, and the cable is placed between the two clamping wheels 2042. The clamping cylinder 2043 controls the two clamping wheels 2042 to clamp the cable. In conjunction with the clamping assembly 110 on the housing 100, it can not only perform the cable changing function of the housing 100, but also improve the stability of the housing 100 during the movement.

[0040] The lifting rod 2045 is designed to work with the rotating second end rod 2033 to remove foreign objects hanging on the cable, ensuring that the housing 100 can move smoothly along the cable, thereby ensuring the smooth progress of the testing process.

[0041] Preferably, the vertical guide rail 2044 is equipped with a push rod that can control the movement of the lifting rod 2045. When there is snow on the cable that is difficult to fall off, the push rod can be controlled to abut against the cable, and the snow on the cable can be cleared by moving the housing 100. At the same time, it can also work with the second air hole 1003 to efficiently clear the snow and ensure smooth movement of the housing.

[0042] In this embodiment, the detection component 120 includes a movable seat 121 slidably disposed on the housing 100. The movable seat 121 is controlled to move on the housing 100 by a second linear mechanism 122. The movable seat 121 is provided with a slidingly engaged arc-shaped plate 123. The sidewall of the arc-shaped plate 123 is provided with an arc-shaped toothed plate 124, which meshes with a drive gear 125. A detection unit 126 is provided on the surface of the arc-shaped plate 123. Specifically, the drive gear 125 can be driven by a motor; the detection unit 126 can be a camera with image detection capabilities.

[0043] In this embodiment, when the housing 100 is placed on the cable and fixed by the clamping assembly 110, the second linear mechanism 122 pushes the movable seat 121 closer to the cable until the detection unit 126 can perform cable surface fault detection. During the detection process, the drive gear 125 can be controlled to rotate, which drives the arc-shaped toothed plate 124 to rotate synchronously, so that the arc-shaped plate 123 rotates around the cable along the movable seat 121, driving the detection unit 126 to detect cable surface faults in all directions, ensuring the comprehensiveness of the detection and improving the detection quality.

[0044] The present invention also provides a cable fault detection method, which uses the cable fault detection device as described above and includes the following steps; Let's take the testing of three cables as an example to illustrate: When the three cables to be tested are at the same height, the housing 100 is placed on the first cable and fixed to it by the clamping assembly 110. The intermediate rod 2031, the first end rod 2032, and the second end rod 2033 are aligned on the same straight line, and the wiring assembly 204 is brought into contact with the first and second cables. Then, the housing 100 is moved along the first cable by the clamping assembly 110, cooperating with the detection assembly 120 to detect the first cable. After the detection of the first cable is completed, the connecting arm 300 is rotated by the rotating mechanism 313, which moves the housing 100 from the first cable to the second cable. At this time, the toothed plate 315 and the toothed groove 303 are in a mating state. That is, the slider 311 is in the locked state, and then the second cable is inspected. After the inspection of the second cable is completed, the toothed plate 315 is moved by the telescopic shaft 314, so that the toothed plate 315 is disengaged from the tooth groove 303. At this time, the slider 311 is in the unlocked state. Then, the first linear mechanism 302 is controlled to move the slider 311 along the waist-shaped hole 301, so that the fixing plate 201 drives the wire changing rods 203 on both sides to move from between the first cable and the second cable to between the second cable and the third cable. Then, the telescopic shaft 314 is controlled to push the toothed plate 315 to connect with the tooth groove. Finally, the connecting arm 300 is controlled to rotate, so that the housing 100 is moved from the second cable to the third cable, and then the third cable is inspected.

[0045] When the three cables to be tested are at different heights, the drive mechanism controls the rotation of the intermediate rod 2031 and the second end rod 2033, causing the intermediate rod 2031 to tilt at an angle equal to the tilt angle between the two cables at different heights. This keeps the first end rod 2032 and the second end rod 2033 in a horizontal position, ensuring that the terminal assembly 204 is in horizontal contact with the cable. In conjunction with the rotation of the connecting arm 300, the housing 100 is moved from the first cable at the current height to the second cable at another height to perform cable crossing detection between different heights.

[0046] It should be noted that when the housing 100 drives the detection component 120 to change the cable, the telescopic mechanism 102 and the boom 202 need to be controlled accordingly to drive the housing 100 and the cable changing boom 203 to move vertically so that they can avoid the obstruction of the cable.

[0047] It should be noted that if the embodiments of the present invention involve directional indicators such as (up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0048] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied. Furthermore, "multiple" refers to two or more. Moreover, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
