Description

Technical Field

[0001] The invention relates to the technical field of cable partial discharge monitoring devices, and in particular to an online cable monitoring device for fault identification. Background Art

[0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of conductors. The cable is affected by electricity, heat, and stress during long-term operation, as well as improper operation during construction and installation, which may cause the cable insulation to be damaged. After the insulation is damaged, the originally uniformly distributed electric field will be concentrated at the damaged area, forming an area with excessively high local electric field intensity, inducing local discharge of the cable. At the same time, during the local discharge process of the cable, due to the rapid transfer of charge and the generation of transient current, according to electromagnetic field theory, a magnetic field will inevitably be generated around the discharge area.

[0003] Currently, inspection robots are usually hoisted on cables. During the movement, the inspection robots detect changes in the magnetic field through the electromagnetic sensors attached to them, and then locate local discharges. However, after the cables are installed, they usually present an arc shape due to their own gravity, and the electromagnetic sensors of the hoisted inspection robots are usually located between their guide wheels. When the inspection robot moves to the lowest point of the cable arc, the distance between the cable and the electromagnetic sensor decreases, which increases the electromagnetic intensity detected by the inspection robot, affecting the final detection results of the inspection robot.

DETAILED DESCRIPTION

[0021] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is 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.

[0022] The installed cables will present an arc shape due to their own gravity. As shown in the process of using the inspection robot to inspect the installed cables, when the inspection robot moves to the lowest point of the cable arc, the vertical distance between the cable and the inspection robot continues to decrease, and the electromagnetic intensity detected by the inspection robot also increases, which affects the final detection result of the inspection robot.

A tension spring is fixedly connected between the electromagnetic sensor and the adjacent connecting plate 15 to maintain the initial position of the electromagnetic sensor and to drive the electromagnetic sensor to reset to the initial position after movement. The tension spring, the adjacent electric push rods 18 and the adjacent guide wheels 19 cooperate with each other to maintain the distance between the electromagnetic sensor and the lower side of the cable to maintain the accuracy of the electromagnetic sensor detection result.

[0023] like Figure 2-Figure 6As shown, the connecting mechanism includes a threaded rod 2, which is rotatably connected to the inside of an adjacent moving column 12. The inside of the moving column 12 is slidably connected with two rectangular plates 21 which are symmetrically distributed up and down. The rectangular plates 21 are threadedly matched with the adjacent threaded rods 2, and the threaded rods 2 drive the two adjacent rectangular plates 21 to move synchronously. The inside of the moving column 12 is slidably connected with two first fixed blocks 22 which are symmetrically distributed up and down. The first fixed blocks 22 are provided with through holes. The threaded rods 2 are located in the through holes of the adjacent first fixed blocks 22, and the diameter of the through holes of the first fixed blocks 22 is larger than the diameter of the adjacent threaded rods 2, so as to avoid the rotation of the threaded rods 2 affecting the position of the first fixed blocks 22. The driving wheel 13 and the guide wheel 14 are rotatably connected to the adjacent first fixed blocks 22 respectively. The first fixed blocks 22 and the adjacent rectangular Springs are fixedly connected between the plates 21 for maintaining the initial positions of adjacent first fixed blocks 22 and driving the first fixed blocks 22 to return to the initial positions after movement. The rectangular plates 21 drive the adjacent first fixed blocks 22 to move synchronously through the transmission of adjacent springs, and through the cooperation of the rectangular plates 21 and adjacent springs, a certain extrusion pressure is maintained between the adjacent driving wheels 13 or guide wheels 14 and the cables. The first fixed blocks 22 are provided with through holes. A first motor 23 electrically connected to the control terminal is fixedly connected to one side of the moving column 12. The output shaft of the first motor 23 and the adjacent threaded rod 2 are driven by a gear set.

[0024] like Figure 4-Figure 7As shown, the adjustment component includes a first liquid storage ring 72, the first liquid storage ring 72 is fixedly connected to the upper side of the movable column 12, the lower side of the first liquid storage ring 72 is sealingly and slidably connected to the movable ring 73, the first liquid storage ring 72 is filled with hydraulic oil, the interior of the first liquid storage ring 72 is fixedly connected with a spring fixedly connected to the adjacent movable ring 73, which is used to maintain the initial position of the adjacent movable ring 73 and drive the movable ring 73 to return to the initial position after movement, the movable ring 73 is squeezed and matched with the adjacent first fixed block 22, and the movable ring 73 moves upward under the squeezing force of the adjacent first fixed block 22, thereby squeezing out the hydraulic oil inside the adjacent first liquid storage ring 72, and the side of the folding plate 11 close to the adjacent first fixed frame 17 is rotatably connected to the second liquid storage ring 74, and the second liquid storage ring 74 and the adjacent first liquid storage ring 72 are connected by The connecting pipe is connected, and a second limit plate 75 is fixedly connected to the inside of the second liquid storage ring 74. The connecting shaft between the movable column 12 and the adjacent folding plate 11 passes through the adjacent second liquid storage ring 74 and is rotatably connected thereto. The inside of the second liquid storage ring 74 is slidably connected with a second positioning plate 76 fixed to the adjacent connecting shaft. The second limit plate 75 and the adjacent second positioning plate 76 are respectively located on both sides of the adjacent connecting pipe. There is a gap between the second limit plate 75 and the adjacent second positioning plate 76, and hydraulic oil is filled between the second limit plate 75 and the adjacent second positioning plate 76. The connecting shaft is rotatably connected to the adjacent folding plate 11, and the second positioning plate 76 moves due to the change in the volume of the hydraulic oil between it and the adjacent second limit plate 75. A moving component for changing the position of the adjacent first fixed frame 17 is provided on the upper side of the movable plate 16.

[0025] like Figure 3 and Figure 8As shown, the moving assembly includes a hydraulic telescopic rod 41, which is fixedly connected to the inside of the adjacent first fixed frame 17, and a spring is fixedly connected between the telescopic end of the hydraulic telescopic rod 41 and its fixed part, which is used to maintain the initial position of the telescopic end of the adjacent hydraulic telescopic rod 41 and drive the telescopic end of the hydraulic telescopic rod 41 to reset to the initial position. A cavity is provided on the upper side of the moving plate 16, and a first limiting plate 42 is fixedly connected in the cavity of the moving plate 16. The first fixed frame 17 is fixedly connected to a fixed shaft 43, which passes through the moving plate 16 and is rotatably connected thereto, and the fixed shaft 43 is fixedly connected to a first positioning plate 44, which slides in the cavity of the adjacent moving plate 16, and the first positioning plate 44 and the adjacent first limiting plate 42 are fixedly connected. 2, a gap is provided between the fixed part of the hydraulic telescopic rod 41 and the cavity of the movable plate 16 are filled with hydraulic oil, the fixed part of the hydraulic telescopic rod 41 is connected to the cavity of the adjacent movable plate 16 through a connecting pipe, the first positioning plate 44 and the adjacent first limiting plate 42 are respectively located on both sides of the adjacent connecting pipe, the telescopic end of the hydraulic telescopic rod 41 is squeezed by the adjacent second fixed block 4 and moves toward its fixed part, so that the hydraulic oil in the fixed part of the hydraulic telescopic rod 41 is transported to the cavity of the adjacent movable plate 16 through the connecting pipe, so as to change the volume of the hydraulic oil between the first positioning plate 44 and the adjacent first limiting plate 42, so that the first positioning plate 44 is squeezed by the hydraulic oil and moves, thereby driving the adjacent first fixed frame 17 to rotate.

[0026] When using this device, the staff sets the single use time and the use interval of the device through the control terminal, and then the staff moves the device to the specified position and starts the four first motors 23. The output shaft of the first motor 23 drives the adjacent threaded rods 2 to rotate through the transmission of the gear group, and the threaded rods 2 drive the two adjacent rectangular plates 21 to move in opposite directions. The rectangular plates 21 drive the adjacent first fixed blocks 22 to move synchronously through the springs.

[0027] During the movement of the first fixing block 22, the four first fixing blocks 22 on the upper side respectively drive the adjacent driving wheels 13 to move downward, and the four first fixing blocks 22 on the lower side respectively drive the adjacent guide wheels 14 to move upward, until the four driving wheels 13 and the four guide wheels 14 are tightly fitted with the cables, the staff turns off the four first motors 23, and the four driving wheels 13 and the four guide wheels 14 cooperate with each other to fix the device (the specific shape is as shown in FIG. Figure 1As shown), the staff then starts the two electric push rods 18, and the telescopic ends of the two electric push rods 18 drive the adjacent second fixed blocks 4 to move downward, and the second fixed blocks 4 drive the adjacent guide wheels 19 to move downward synchronously, until the two guide wheels 19 move downward to contact the upper side of the cable, and when the guide wheels 19 continue to move downward, the cable intercepts the adjacent guide wheels 19, so that the fixed part of the electric push rod 18 drives the adjacent first fixed frame 17 to move upward, and the first fixed frame 17 drives the electromagnetic inductor thereon and the adjacent moving plate 16 to move upward synchronously to change the distance between the adjacent electromagnetic inductor and the cable. In the process of the electromagnetic inductor moving upward, the tension spring between it and the adjacent connecting plate 15 is stretched and stored until the staff adjusts the two electromagnetic inductors to the appropriate position, and then the staff shuts down the two electric push rods 18 (at this time, the tension springs between the two electromagnetic inductors and the adjacent moving plates 16 are in a stretched state, but neither is stretched to the limit state).

[0028] After installing the device, the staff starts the four driving wheels 13 through the control terminal, and the four driving wheels 13 drive the device to move to the right. At the same time, the control terminal starts the electromagnetic sensor, and the electromagnetic sensor monitors the cable. During the monitoring process, when the insulation of the cable is damaged, the cable generates a discharge area at the damaged position and generates an electromagnetic field, thereby triggering the electromagnetic sensor. When the device moves to the position where the electromagnetic sensor detects the maximum value (i.e., the cable damaged position), the device marks the point and transmits the detection result to the remote control terminal. The staff then inspects the damaged cable.

[0029] In the process of the above-mentioned movement of the device, when the device moves to the lowest point of the cable (the cable between the two poles is in an arc shape under normal conditions due to its own gravity), the distance between the cable and the outer shell 1 is reduced, and at the same time, the force of the cable on the two guide wheels 19 is reduced, so that the tension on the tension springs between the two electromagnetic sensors and the adjacent connecting plates 15 is reduced, so that the two tension springs are reset to the initial state, thereby driving the two electromagnetic sensors and other parts connected thereto to move downward synchronously, so that the two guide wheels 19 are always in contact with the upper side of the adjacent cables. At this time, the relative position between the guide wheel 19 and the adjacent first fixing frame 17 is kept constant under the action of the adjacent electric push rod 18, so that the distance between the electromagnetic sensor and the cable is always constant, avoiding that when the device moves to the lowest point of the cable, the distance between the electromagnetic sensor and the lower side of the cable is reduced, resulting in an impact on the value detected by the electromagnetic sensor when the cable is damaged, thereby misjudging the location of the cable damage, affecting the subsequent maintenance of the cable.

[0030] In the process of the above-mentioned device moving to the right, when the device moves to the position in contact with the cross arm on the electric pole, the control terminal shuts down the four driving wheels 13, and simultaneously reversely starts the two first motors 23 on the right side, so that the two driving wheels 13 on the right side and the two guide wheels 14 on the right side are separated from the cable, until the four rectangular plates 21 on the right side are all moved to the initial position (at this time, the two first fixed blocks 22 on the upper right side are respectively in contact with the adjacent moving rings 73), and the two first fixed blocks 22 on the upper right side continue to move upward to squeeze the adjacent moving rings 73, so that the four moving rings 73 move upward, thereby moving the four first liquid storage rings 73 upward. The hydraulic oil in 72 is squeezed into the adjacent second liquid storage ring 74 through the connecting pipe, increasing the volume of the hydraulic oil between the adjacent second limit plate 75 and the adjacent second positioning plate 76, so that the adjacent second positioning plate 76 is squeezed by the hydraulic oil and drives the adjacent connecting shaft to rotate, thereby driving the adjacent moving columns 12 and other parts connected thereto to rotate synchronously, until the two moving columns 12 on the right side have rotated 90°, and the control terminal shuts down the two first motors 23 on the right side. At this time, the two moving columns 12 on the right side and other parts connected thereto are all located on the lower side of the cable, so that the above-mentioned parts are completely separated from the cable.

[0031] While the control terminal shuts down the two first motors 23 on the right, the control terminal starts the two driving wheels 13 on the left. Under the action of the two driving wheels 13 on the left, the two moving columns 12 on the right side of the device continue to move to the right during the rotation process, so as to avoid the cross arm affecting the normal movement of the device when the device moves along the cable to the position in contact with the cross arm, and at the same time shorten the length of the cable monitored by the device. After the two moving columns 12 on the right side pass over the cross arm, the control terminal starts the two first motors 23 on the right side again, and the two first motors 23 on the right side respectively drive the adjacent moving columns 12 and other parts connected thereto to move synchronously to the vertical position, until the moving column 12 moves to the vertical position again, and the two first motors 23 on the right side respectively drive the adjacent driving wheels 13 and the adjacent guide wheels 14 to approach each other, until the two driving wheels 13 on the right side and the two guide wheels 14 on the right side move to the position in contact with the cable again, and the control terminal shuts down the two first motors 23 on the right side again.

[0032] While the control terminal shuts down the two first motors 23 on the right side again, the control terminal starts the two electric push rods 18 in reverse, and the telescopic ends of the two electric push rods 18 respectively drive the adjacent guide wheels 19 to move upward through the adjacent second fixed blocks 4, so that the two guide wheels 19 are respectively separated from the adjacent cables. In the process of the guide wheels 19 moving upward, the tension springs between the two electromagnetic sensors and the adjacent connecting plates 15 are synchronously reset to the initial state, thereby driving the adjacent electromagnetic sensors and the adjacent moving plates 16 to move downward synchronously until the tension springs are reset to the initial state (at this time, the second fixed block 4 is in contact with the telescopic end of the adjacent hydraulic telescopic rod 41, but the telescopic end of the electric push rod 18 has not moved to the extreme position, and the guide wheel 19 is not in contact with the upper side of the cable), and the adjacent moving plates 16 and the telescopic ends of the electric push rods 18 are synchronously moved to the initial position.

[0033] When the telescopic end of the electric push rod 18 continues to drive the adjacent parts to move upward, the adjacent second fixed block 4 squeezes the telescopic end of the adjacent hydraulic telescopic rod 41, so that the telescopic end of the adjacent hydraulic telescopic rod 41 moves upward, and squeezes the hydraulic oil in its fixed part into the cavity on the adjacent movable plate 16 through the connecting pipe, thereby increasing the volume of the hydraulic oil between the first limit plate 42 and the adjacent first positioning plate 44, so that the adjacent first positioning plate 44 drives the adjacent fixed shaft 43 to rotate, and the fixed shaft 43 drives the adjacent first fixed frame 17 and other parts connected thereto to rotate synchronously, until the first fixed frame 17 rotates 90°, the control terminal shuts down the electric push rod 18 to prevent the cross arm from squeezing the two first fixed frames 17 during the continued movement of the device, causing the two first fixed frames to 17 is damaged, until the two first fixed frames 17 have passed over the crossarm, the control terminal starts the electric push rod 18 again, retracts the telescopic end of the electric push rod 18 into its fixed part, and at the same time makes the telescopic end of the adjacent hydraulic telescopic rod 41 move downward under the action of the adjacent spring, and then draws the hydraulic oil in the cavity on the movable plate 16 back to the fixed part of the hydraulic telescopic rod 41, so that the adjacent first fixed frames 17 are reset to the vertical position, until the two first fixed frames 17 are reset to the vertical position, the telescopic ends of the two electric push rods 18 respectively drive the adjacent guide wheels 19 to move to the position in contact with the upper side of the adjacent cables (the specific process can be referred to above), until the two first fixed frames 17 and other parts connected thereto are synchronously reset to the initial position, and the control terminal shuts down the two electric push rods 18.

[0034] The movement process of the two movable columns 12 on the left side of the device when they contact the cross arm is the same as the movement process of the two movable columns 12 on the right side, and the movement process of the device to the left can refer to the movement process of the device to the right.

[0035] When the inspection robot inspects the cable, if dust is attached to the damaged part of the cable, the electromagnetic waves generated by the partial discharge may be absorbed, scattered or attenuated by the dust, causing the intensity and characteristics of the detected partial discharge signal to change, affecting the fault location and judgment. Therefore, the present invention makes changes to this through the following operations: Embodiment 2: Based on embodiment 1, Figure 2 and Figure 9-11 As shown, it also includes a cleaning mechanism, which is used to clean the dust on the cable surface. The cleaning mechanism is arranged on the left and right sides of the outer shell 1. The cleaning mechanism includes two U-shaped frames 5 that are symmetrically distributed on the left and right sides. The two U-shaped frames 5 are both limited and slidably connected to the outer shell 1. The back sides of the two U-shaped frames 5 are provided with detectors (which are existing devices and not shown in the figure) that are electrically connected to the control terminal. The detector is used to monitor the distance between the device and the cross arm. The upper side of the U-shaped frame 5 is rotatably connected to two groups of arc plates 51 that are symmetrically distributed in the front and back. Each group of arc plates 51 is arranged to be two adjacent arc plates 51 that are symmetrically distributed in the center. The hinged connection, the arc plate 51 is rotatably connected to an arc rack 52, and the adjacent two arc racks 52 are symmetrical. The arc racks 52 are arranged in a distributed manner, two adjacent arc-shaped racks 52 are hinged, and in the initial position, the hinge axis of the arc-shaped racks 52 is concentric with the hinge axis of the adjacent arc-shaped plate 51, the curvature of the two adjacent arc-shaped racks 52 is the same, and the arc-shaped racks 52 are semicircular, and a cleaning brush is arranged inside the arc-shaped racks 52 for cleaning the dust on the surface of the cable. The arc-shaped plates 51 on the front and rear sides are fixedly connected with a second motor 53 electrically connected to the control terminal, and the output shaft of the second motor 53 is fixedly connected with a gear meshing with the adjacent arc-shaped racks 52, and the output shaft of the second motor 53 drives the adjacent arc-shaped racks 52 and the cleaning brush inside thereof to rotate through the meshing of the gears, so as to clean the dust on the surface of the cable, and the outer shell 1 is provided with a trigger component for changing the position of the arc-shaped racks 52.

[0036] like Figure 9-13As shown, the trigger assembly includes a double-axis motor 6, a rectangular groove is provided at the lower part of the outer shell 1, the double-axis motor 6 is fixedly connected to the rectangular groove of the outer shell 1, the double-axis motor 6 is electrically connected to the control terminal, two push plates 61 symmetrically distributed in a sliding connection are provided in the rectangular groove of the outer shell 1, the double-axis motor 6 is provided with two output shafts, the two output shafts of the double-axis motor 6 are fixedly connected to screws, the push plates 61 are threadedly connected to adjacent screws, four first telescopic rods 62 distributed in a matrix are fixedly connected in the rectangular groove of the outer shell 1, the fixed part of the first telescopic rod 62 is filled with hydraulic oil, the telescopic end of the first telescopic rod 62 is fixedly connected to the adjacent push plate 61, the telescopic end of the first telescopic rod 62 is synchronously moved by the movement of the adjacent push plate 61, and the outer shell The outer shell 1 is provided with four grooves distributed in a matrix. A liquid storage tube 63 is fixedly connected in the groove of the outer shell 1. The liquid storage tube 63 is filled with hydraulic oil. The liquid storage tube 63 is connected to the fixed part of the adjacent first telescopic rod 62 through a connecting pipe. A push plate 65 is slidably connected inside the liquid storage tube 63. The hydraulic oil in the fixed part of the first telescopic rod 62 drives the adjacent push plate 65 to move. An arc-shaped baffle 64 is fixedly connected to the lower side of the push plate 65. The arc-shaped baffle 64 is located inside the adjacent liquid storage tube 63. The arc-shaped baffle 64 is telescopic. The telescopic end of the arc-shaped baffle 64 slides on the inner side of the adjacent liquid storage tube 63. A slide groove that slides with the adjacent push plate 65 is provided on the side of the liquid storage tube 63 away from the outer shell 1. The arc-shaped baffle 64 pushes the adjacent The slide groove on the liquid storage tube 63 is shielded to prevent the hydraulic oil in the liquid storage tube 63 from leaking outward. A second telescopic rod 66 is fixedly connected to the upper side of the push plate 65. The telescopic end of the second telescopic rod 66 is fixedly connected to the adjacent U-shaped frame 5. The push plate 65 drives the adjacent U-shaped frame 5 to move through the transmission of the adjacent second telescopic rod 66. A spring is fixedly connected between the fixed part of the second telescopic rod 66 and the adjacent U-shaped frame 5 to maintain the initial position of the adjacent U-shaped frame 5 and drive the U-shaped frame 5 to reset to the initial position after moving. Two hydraulic push rods 67 distributed symmetrically in front and back are inlaid on the upper end of the U-shaped frame 5. The hydraulic push rod 67 is located below the adjacent arc plate 51. The telescopic end of the hydraulic push rod 67 is fixedly connected to a second fixed frame 68. The second fixed frame The frame 68 is composed of a horizontal plate and two inclined columns distributed in a centrally symmetrical manner. The second fixed frame 68 is slidably matched with the adjacent U-shaped frame 5. The fixed part of the hydraulic push rod 67 is connected to the fixed part of the adjacent second telescopic rod 66 through a connecting pipe. When the U-shaped frame 5 moves to the extreme position, the push plate 65 moves upward to move the telescopic end of the second telescopic rod 66 toward its fixed part, and transports the hydraulic oil in the fixed part to the fixed part of the adjacent hydraulic push rod 67. The upper end of the second fixed frame 68 is hinged with a hinged column that is slidably matched with the adjacent arc plate 51. The second fixed frame 68 moves upward to drive the two adjacent arc plates 51 and the adjacent arc racks 52 to rotate synchronously, and the two adjacent arc racks 52 are combined into a gear ring.

[0037] During the process of the above-mentioned device moving to the right, the control terminal starts the dual-axis motor 6, and the transmission of the synchronous thread of the output shaft of the dual-axis motor 6 drives the two push plates 61 to move in opposite directions. The movement of the right push plate 61 is described as an example: the push plate 61 drives the telescopic ends of the two adjacent first telescopic rods 62 to move synchronously to the right, and the telescopic ends of the first telescopic rods 62 transfer the hydraulic oil in their fixed parts to the adjacent liquid storage tubes 63 through the connecting pipe during the movement, thereby increasing the volume of the hydraulic oil in the adjacent liquid storage tubes 63, and then causing the adjacent push plates 65 to move upward along the slide grooves on the adjacent liquid storage tubes 63, and the push plates 65 drive the fixed parts of the adjacent arc-shaped baffles 64 to move synchronously, and the telescopic parts and fixed parts of the arc-shaped baffles 64 cooperate with each other to block the slide grooves on the adjacent liquid storage tubes 63, thereby preventing the hydraulic oil in the liquid storage tubes 63 from leaking out.

[0038] In the process of moving upward, the push plate 65 drives the adjacent second telescopic rod 66 to move upward synchronously, and the cooperation of the two second telescopic rods 66 on the right side drives the adjacent U-shaped frame 5 to move upward synchronously, thereby driving the four arc plates 51 and the four arc racks 52 on the right side to move upward synchronously, until the U-shaped frame 5 on the right side moves upward to the limit position, that is, when the cable is located at the center of the two adjacent arc racks 52, the U-shaped frame 5 and other parts connected thereto stop moving upward synchronously due to the limitation of the outer shell 1. At this time, the two push plates 65 on the right side drive the adjacent second telescopic rod 66 to continue to move upward, and the telescopic end of the second telescopic rod 66 on the right side is limited by the adjacent U-shaped frame 5 and moves toward its fixed part, so that the second telescopic rod 66 is extended. The spring between the retracted end and the adjacent U-shaped frame 5 is compressed and stored, and at the same time, the hydraulic oil in the fixing part of the second telescopic rod 66 is squeezed out into the fixing part of the adjacent hydraulic push rod 67 through the connecting pipe, so that the telescopic end of the adjacent hydraulic push rod 67 moves upward, thereby driving the adjacent second fixing frame 68 to move upward, and the second fixing frame 68 drives the two adjacent hinged columns to move upward synchronously. As the second fixing frame 68 moves upward, the distance between the second fixing frame 68 and the two adjacent arc-shaped plates 51 gradually decreases, and at the same time, the two arc-shaped plates 51 are moved by the upward squeezing force of the adjacent second fixing frame 68, and the two arc-shaped plates 51 respectively drive the adjacent arc-shaped racks 52 to rotate synchronously until the upper sides of the two adjacent arc-shaped racks 52 are fitted (such as Fig.11 As shown), the telescopic ends of adjacent hydraulic push rods 67 move synchronously to the limit positions, and then the control terminal shuts down the dual-axis motor 6.

[0039] While the above-mentioned control terminal shuts down the dual-axis motor 6, the control terminal starts the two second motors 53 on the right side. The output shaft of the second motor 53 drives the two adjacent arc-shaped racks 52 to rotate along the two adjacent arc-shaped plates 51 through the spur gear, and the cleaning brushes inside the two arc-shaped racks 52 clean the dust attached to the cable surface to prevent the dust attached to the cable from affecting the normal use of the electromagnetic sensor, thereby ensuring the accuracy of the monitoring results of the electromagnetic sensor.

[0040] During the process of the device moving to the right, the detector on the right U-shaped frame 5 always measures the distance between it and the adjacent cross arm. When the detector on the right U-shaped frame 5 reaches the specified value (that is, when the detector and the cross arm reach the specified distance), the control terminal reversely starts the dual-axis motor 6, and the output shaft of the dual-axis motor 6 drives the two push plates 61 to move in the opposite direction. The two push plates 61 respectively drive the telescopic ends of the adjacent first telescopic rods 62 to move in the opposite direction, thereby driving the arc-shaped rack 52 and other parts connected thereto to synchronously reset downward (the specific process is opposite to the above-mentioned process of positive starting of the dual-axis motor 6, but it can still be referred to above), so as to avoid affecting the normal movement of the device due to the position of the U-shaped frame 5.

[0041] When the control terminal reversely starts the dual-axis motor 6, the control terminal reversely starts the two first motors 23 on the right side, and while the two U-shaped frames 5 move downward, the two movable columns 12 on the right side rotate synchronously (the specific process can be referred to above). After the device completely moves over the crossarm, the control terminal starts the dual-axis motor 6 again, driving the two U-shaped frames 5 and other parts connected thereto to move upward again to a position that cooperates with the cable, so as to continue to clean the dust attached to the cable.

[0042] Considering that the inspection robot is usually powered by a battery during use, if the battery power is low, the inspection robot cannot inspect the cable normally. At the same time, after the inspection robot has been used for a period of time, the dust attached to it will also have a certain impact on the normal use of the inspection robot. For example, the dust attached to the electromagnetic sensor may affect the normal detection result of the electromagnetic sensor, and the dust attached to the driving wheel may reduce the friction between the driving wheel and the surface of the cable. Therefore, the present invention makes the following changes: Embodiment 3: Based on embodiment 2, Figure 1 and Fig. 9As shown, it also includes a battery life mechanism, which is used to enable the outer shell 1 to work continuously. The battery life mechanism is arranged on one side of the outer shell 1, and the battery life mechanism includes a fixing plate 7. The fixing plate 7 is located on one side of the outer shell 1, and the fixing plate 7 is fixed to the upper end of the electric pole through a connecting piece. A cleaning box 71 is fixed to the upper side of the fixing plate 7, and a cleaning device and a charger are arranged inside the cleaning box 71. The cleaning device and the charger are both electrically connected to the control terminal, and the cleaning device and the charger are both existing devices, which are not shown in the figure. Four electric wheels distributed in a matrix and matched with the fixing plate 7 are arranged on the lower side of the outer shell 1, and the electric wheels are electrically connected to the control terminal.

[0043] In the process of installing the device, the staff installs the fixing plate 7 on the designated electric pole. When the device moves to the right to a position in contact with the left side of the fixing plate 7, the control terminal starts the four electric wheels on the lower side of the outer shell 1. The four electric wheels on the lower side of the outer shell 1 cooperate with the four driving wheels 13 to drive the device to move until the four electric wheels on the lower side of the outer shell 1 are all on the fixing plate 7. The control terminal resets the driving wheels 13, the U-shaped frame 5, and the moving column 12 to their initial positions (refer to the above for the specific process), so that the device is separated from the cable.

[0044] When the device moves to the inside of the cleaning box 71 driven by the four electric wheels, the control terminal shuts down the four electric wheels and transmits the message that the device is now inside the cleaning box 71 to the remote control terminal. The remote control terminal starts the cleaning device inside the cleaning box 71 to clean the dust attached to the device to prevent the dust attached to the device from affecting the normal use of the device. At the same time, the device is charged to avoid insufficient power during the use of the device.

[0045] After the device is charged, the control terminal starts the four electric wheels again, and the four electric wheels drive the device to continue moving. When the device loses contact with the cleaning box 71, the control terminal reconnects the device to the cable. The specific process can be referred to above.

[0046] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
