Description

Technical Field

[0001] This invention relates to the field of power system maintenance equipment, and more specifically, to a power system testing and maintenance device. Background Technology

[0002] Underground cables offer greater safety compared to overhead lines. Overhead lines, being exposed to the air, are more susceptible to external interference such as lightning strikes, wind, birds, or human sabotage, which can lead to power outages or fires.

[0003] Underground cables, buried underground and encased in protective and insulating layers, are less susceptible to external influences, resulting in more stable and reliable operation. Furthermore, underground cables prevent dangers such as electric shock, protecting people's lives and property.

[0004] Currently, most underground cable burial corridors use cable racks and cable limiting structures to limit and fix the cables. They also have automated inspection equipment. However, these inspection devices can only perform traversal inspections of the cables, such as detecting partial discharge. They cannot pre-treat and maintain areas with partial discharge, especially the parts of the cable that are limited and fixed by the limiting components. These areas are blind spots for inspection and maintenance and still require manual inspection and maintenance, which increases labor costs and poses personal safety hazards.

Detailed Implementation

[0031] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed merely to enable those skilled in the art to better understand and implement the subject matter described herein. Furthermore, features described in some examples may be combined in other examples.

[0032] like Figures 1-11 As shown, a power system testing and maintenance device includes a mobile vehicle body 1, a Y-axis moving component 2 mounted on the mobile vehicle body 1, a first adjustment mechanism connected to the Y-axis moving component 2, a second adjustment mechanism connected to the mobile vehicle body 1, a disassembly and assembly mechanism 5 connected to the first adjustment mechanism, and a maintenance mechanism 6 connected to the second adjustment mechanism. The second adjustment mechanism is located on the mobile vehicle body 1 near the middle of the Y-axis moving component 2. The first and second adjustment mechanisms are used to adjust the spatial positions of the disassembly and assembly mechanism 5 and the maintenance mechanism 6, respectively. The disassembly and assembly mechanism 5 is used to disassemble or install the limiting component on the cable rack for fixing the cable. The maintenance mechanism 6 is used to collect data on the partial discharge area of ​​the cable and wrap insulating tape around the partial discharge area on the cable.

[0033] The disassembly and assembly mechanism 5 includes a first bidirectional adjustment component 51 connected to the first adjustment mechanism, a second bidirectional adjustment component 52 connected to the first bidirectional adjustment component 51, and two disassembly and assembly components 53 symmetrically connected to the first bidirectional adjustment component 51. The first bidirectional adjustment component 51 is arranged along the X-axis and is used to drive the two disassembly and assembly components 53 to move closer or further away from each other. The second bidirectional adjustment component 52 is arranged along the Y-axis.

[0034] The maintenance mechanism 6 includes a third bidirectional adjustment component 61 connected to the first adjustment mechanism, two semi-circular moving components 62 symmetrically connected to the third bidirectional adjustment component 61, a power drive component and an insulating tape output component 63 disposed in one of the semi-circular moving components 62, an auxiliary clamping component 64 disposed in the other semi-circular moving component 62, and a partial discharge detection terminal 65 connected to the housing of the semi-circular moving component 62. The third bidirectional adjustment component 61 is used to drive the two semi-circular moving components 62 to move closer or further apart from each other. When the two semi-circular moving components 62 are in contact, they form a complete circular track. The power drive component is used to drive the insulating tape output component 63 to move along the circular track. The auxiliary clamping component 64 is used to clamp one end of the insulating tape output component 63 that outputs the insulating tape.

[0035] It should be noted that during the inspection of underground cables, the maintenance mechanism 6 is first separated under the drive of the third bidirectional adjustment component 61. At this time, one end of the insulating tape in the insulating tape output component 63 is clamped by the auxiliary clamping component 64. After the two semi-circular moving components 62 separate, the insulating tape is stretched, but this does not affect its subsequent use. The semi-circular moving components 62 are moved to the outside of the cable to be tested by the second adjustment mechanism and the third bidirectional adjustment component 61. After the two semi-circular moving components 62 are sleeved on the outside of the cable and come into contact with each other, the insulating tape output component 63 can retract the stretched insulating tape. Then, the moving vehicle 1 moves along the length of the cable. When the moving vehicle 1 moves, it drives the first adjustment mechanism, the second adjustment mechanism disassembly and assembly mechanism 5, and the maintenance mechanism 6 to move in the same direction and at the same distance, thereby performing a traversal inspection of the cable. When the maintenance mechanism 6 moves to the cable limiting structure, the first bidirectional adjustment component 51 drives the disassembly and assembly component 6 to move in the same direction and at the same distance. The component 53 moves to the connecting bolt on the cable limiting structure. The connecting bolt is removed by the disassembly and assembly component 53, and the disassembled limiting structure, such as the limiting ring, is clamped by the second bidirectional adjustment component 52. After the limiting structure and connecting bolt are removed, the disassembly and assembly component 5 and the cable limiting mechanism are moved to the area that the maintenance mechanism 6 has detected by the Y-axis moving component 2 and the first adjustment mechanism. When the maintenance mechanism 6 passes the position where the cable was previously limited, the cable limiting mechanism is reinstalled by the disassembly and assembly component 5. After installation, the disassembly and assembly component 5 is moved back to the area that the maintenance mechanism 6 has not detected by the maintenance mechanism 6 by the Y-axis moving component 2 and the first adjustment mechanism, thus preparing for the next disassembly of the cable limiting structure. When the partial discharge detection terminal 65 detects a partial discharge signal on the cable, the insulating tape output component 63 can be driven by the power drive component to rotate around the cable and wrap the insulating tape around the cable, thereby performing maintenance.

[0036] The first adjustment mechanism includes a first Z-axis telescopic component 31 connected to the Y-axis moving component 2, a first rotary motor 32 connected to the first Z-axis telescopic component 31, a first connecting plate 33 connected to the output shaft end of the first rotary motor 32, and a first X-axis telescopic component 34 connected to the first connecting plate 33. The Y-axis moving component 2, the first Z-axis telescopic component 31, and the first X-axis telescopic component 34 are all screw-slider structures, cylinders, or hydraulic cylinders.

[0037] It should be noted that, as described above, the first adjustment mechanism can drive the first rotary motor 32, the first connecting plate 33, and the first X-axis telescopic component 34 to move along the Z-axis via the first Z-axis telescopic component 31, thereby adjusting the height of the disassembly and assembly mechanism 5. The first rotary motor 32 can drive the first connecting plate 33 to rotate at a set angle, thereby moving the disassembly and assembly mechanism 5 to or from the corresponding frame. The first X-axis telescopic component 34 can drive the disassembly and assembly mechanism 5 to move along the X-axis, allowing it to move to different positions on the cable rack above the cables. The Y-axis moving component 2 can drive the first Z-axis telescopic component 31 to move along the Y-axis, thereby adjusting the position of the disassembly and assembly mechanism 5 on the maintenance path and realizing the disassembly and installation process of the cable limiting structure.

[0038] The second adjustment mechanism includes a second Z-axis telescopic assembly 41 connected to the mobile vehicle body 1, a second rotary motor 42 connected to the second Z-axis telescopic assembly 41, a second connecting plate 43 connected to the output shaft end of the second rotary motor 42, and a second X-axis telescopic assembly 44 connected to the second connecting plate 43. The second Z-axis telescopic assembly 41 and the second X-axis telescopic assembly 44 are both screw-slider structures, cylinders, or hydraulic cylinders.

[0039] It should be noted that the second regulating mechanism works on the same principle as the first regulating mechanism.

[0040] The first bidirectional adjustment component 51, the second bidirectional adjustment component 52, and the third bidirectional adjustment component 61 each include a fixed track, a first lead screw movably connected to the inner wall of the fixed track, a second lead screw connected to one end of the first lead screw, an integrated motor fixedly connected to the fixed track, and two sliding plates slidably connected to the fixed track. The output shaft of the integrated motor is connected to the first lead screw, and the threads of the first and second lead screws are opposite in direction. The two sliding plates are threadedly connected to the first and second lead screws respectively, and one end of each sliding plate extends to the outside of the fixed track. The outer shell of the second bidirectional adjustment component 52 is fixedly connected to the outer shell of the first bidirectional adjustment component 51.

[0041] It should be noted that the working principle of the first bidirectional adjustment component 51, the second bidirectional adjustment component 52 and the third bidirectional adjustment component 61 is the same. They all use an integrated motor to drive the first lead screw and the second lead screw to rotate in the same direction and at the same angle. When the first lead screw and the second lead screw rotate in the same direction, they can drive the two slide plates to move closer or further apart. When the two slide plates in the second bidirectional adjustment component 52 move closer together, they can clamp the upper part of the cable limiting structure.

[0042] The disassembly and assembly component 53 includes a connecting frame 5301, a first micro motor 5302 fixedly connected to the connecting frame 5301, a first screw 5303 connected to the output shaft end of the first micro motor 5302, a first slider 5304 and a second slider 5305 slidably connected to the connecting frame 5301, a first spring 5306 connected between the first slider 5304 and the second slider 5305, a second micro motor 5307 connected to the second slider 5305, and a disassembly terminal 5308 detachably connected to the output shaft end of the second micro motor 5307. The first slider 5304 is threadedly connected to the first screw 5303, and the second slider 5305 has a through hole with a diameter larger than that of the first screw 5303. The connecting frame 5301 is connected to the slide plate of the first bidirectional adjustment component 51.

[0043] It should be noted that, as mentioned above, when the disassembly assembly 53 disassembles the connecting bolts on the cable limiting structure, since the nuts are mostly welded to the cable rack, it is only necessary to rotate the stud by the disassembly assembly 53. Specifically, the first micro motor 5302 drives the first screw 5303 to rotate. When the first screw 5303 rotates, it drives the first slider 5304 to move towards the stud. When the first slider 5304 moves, it drives the second slider 5305 to move in the same direction and distance through the first spring 5306 until the disassembly terminal 5308 is tightly engaged with the stud. At this time, the second micro motor 5307 drives the disassembly terminal 5308 to rotate. When the second disassembly terminal 5308 rotates, it drives the second slider 5305 to move in the same direction and distance through the first spring 5306 until the disassembly terminal 5308 is tightly engaged with the stud. At this time, the second micro motor 5307 drives the disassembly terminal 5308 to rotate. The stud rotates, and since the nut is welded to the cable frame, the stud will continuously move upward during rotation, pushing the disassembly terminal 5308, the second micro motor 5307, and the second slider 5305 upward. At this time, the first spring 5306 deforms along with the movement of the second slider 5305 and always provides support force. When the stud is unscrewed, it no longer moves upward. At this time, the upper part of the cable limiting structure is clamped by the second bidirectional adjustment component 52, and then the upper part of the cable limiting structure can be removed. When it is removed, the first spring 5306 is compressed again, and the stud is reinserted into the hole of the upper part of the cable limiting structure. The disassembly terminal 5308 and the stud are still in a mating state.

[0044] The semi-annular moving component 62 includes a C-shaped semi-annular housing 6201, a semi-annular slide rail 6202 fixedly connected to the inner wall of the C-shaped semi-annular housing 6201, a semi-annular sliding frame 6203 slidably connected to the semi-annular slide rail 6202, and a semi-annular gear 6204 connected to the inner circular surface of the semi-annular sliding frame 6203. When the two semi-annular slide rails 6202 are in contact, they form a complete annular slide rail. When the two semi-annular sliding frames 6203 are in contact, they form a complete annular sliding frame. When the two semi-annular gears 6204 are in contact, they form a complete annular gear. The C-shaped semi-annular housing 6201 is connected to the slide plate of the third bidirectional adjustment component 61.

[0045] The power drive assembly includes a third micro motor 6205 and a transmission gear 6206 connected to the output shaft end of the third micro motor 6205. The third micro motor 6205 is fixedly connected to the inner wall of one of the C-shaped semi-annular housings 6201, and the transmission gear 6206 meshes with the semi-annular gear 6204.

[0046] It should be noted that, as described above, when the insulating tape output assembly 63 is driven to rotate around the cable, the third micro motor 6205 drives the transmission gear 6206 to rotate. When the transmission gear 6206 rotates, it drives the assembled ring gear to rotate. When the ring gear rotates, it drives the assembled ring sliding frame to rotate. When the ring sliding frame rotates, it drives the insulating tape output assembly 63 connected to it to rotate in the same direction and at the same angle. When the insulating tape output assembly 63 rotates, one end of the insulating tape output inside is clamped by the auxiliary clamping assembly 64. When the insulating tape output assembly 63 rotates, the insulating tape between the two can be wrapped around the cable. However, it should be noted that initially, the insulating tape output assembly 63 should be controlled to rotate one to two revolutions. During this process, the auxiliary clamping assembly 64 releases one end of the insulating tape, and the other end of the insulating tape can also be wrapped around the cable by subsequent insulating tape.

[0047] The insulating tape output assembly 63 includes a fixed housing 6301, a first cavity 6302 disposed inside the fixed housing 6301, a tape roll 6304 movably connected to the inner wall of the first cavity 6302, a tape outlet 6303 disposed on the fixed housing 6301, a first groove 6306 disposed on one side wall of the tape outlet 6303, a fixed cutter 6305 connected to the other side wall of the tape outlet 6303, a first electromagnet 6307 fixedly connected to the inner wall of the first groove 6306, a first permanent magnet 6309 slidably connected to the inner wall of the first groove 6306, and a component connected to the first permanent magnet 6309. The movable cutter 6310 on 309 and the second spring 6308 connected between the first electromagnet 6307 and the first permanent magnet 6309, the tape outlet 6303 communicates with the first cavity 6302, the movable cutter 6310 is correspondingly arranged with the fixed cutter 6305, the tape roll 6304 is provided with a torsion spring at the connection with the first cavity 6302, the inner wall of the tape outlet 6303 is movably connected with a set of conveying rollers, the fixed housing 6301 is connected with a fourth micro motor, the output end of the fourth micro motor is connected to one of the conveying rollers, and the fixed housing 6301 is fixedly connected to the semi-ring sliding frame 6203;

[0048] The inner wall of the C-shaped semi-ring housing 6201 is connected to a second semi-ring power supply component 72, and the first electromagnet 6307 and the fourth micro motor are both electrically connected to the second semi-ring power supply component 72.

[0049] It should be noted that, as mentioned above, the insulating tape is pulled out from the tape roll 6304. Due to the action of the torsion spring, the insulating tape can be recycled. After the two C-shaped semi-ring housings 6201 are spliced ​​together, it is necessary to control the insulating tape output assembly 63 to move it close to the auxiliary clamping assembly 64 to prevent the pulled-out insulating tape from affecting the entire equipment's movement along the cable. When winding, the force provided by the torsion spring allows the insulating tape to be tightly wound onto the cable. At this time, the conveyor roller group does not work and does not affect the continuous output of the insulating tape under external force. After the insulating tape has finished winding the partial discharge area, it is transferred to the second semi-ring housing. When the power supply component 72 is de-energized, the first permanent magnet 6309 is de-energized. At this time, the first permanent magnet 6309 moves toward the fixed cutter 6305 under the action of the second spring 6308, and pushes the moving cutter 6310 to move in the same direction and distance. The moving cutter 6310 makes close contact with the fixed cutter 6305 under the action of the elastic force, and cuts the insulating tape between the two. After cutting, the second semi-circular power supply component 72 is energized, and the fourth micro motor and the first electromagnet 6307 are energized, so that they can work again. The fourth micro motor can drive the conveyor roller group to continuously output the insulating tape, so that one end of the insulating tape moves to the auxiliary clamping component 64.

[0050] The auxiliary clamping assembly 64 includes an arc-shaped housing 6401, a clamping groove 6402 disposed on the inner circular surface of the arc-shaped housing 6401, a second cavity 6403 disposed inside the arc-shaped housing 6401, a second electromagnet 6404 connected to the inner wall of the second cavity 6403, a second permanent magnet 6405 slidably connected to the inner wall of the second cavity 6403, a movable clamping block 6406 connected to the second permanent magnet 6405, a fixed clamping block 6407 connected to the inner wall of the clamping groove 6402, and a fan-shaped wiring plate 64 connected to the arc-shaped housing 6401. 09. An electric telescopic rod 6408 is disposed inside the arc-shaped housing 6401, and a plug rod 6410 is connected to the output end of the electric telescopic rod 6408. A first semi-ring power supply component 71 is connected to the inner wall of the C-shaped semi-ring housing 6201. A fan-shaped terminal block 6409 is slidably connected to the first semi-ring power supply component 71. A second electromagnet 6404 is electrically connected to the first semi-ring power supply component 71. A damping layer is provided at the sliding connection between the first semi-ring power supply component 71 and the fan-shaped terminal block 6409. A plug hole that cooperates with the plug rod 6410 is provided on the semi-ring sliding frame 6203.

[0051] It should be noted that, as mentioned above, after the insulating tape is cut and one end of the subsequent insulating tape is conveyed to the auxiliary clamping assembly 64, the third bidirectional adjustment assembly 61 needs to drive the two C-shaped semi-ring housings 6201 to separate again. During separation, the insulating tape output assembly 63 returns to its initial position. After the C-shaped semi-ring housings 6201 are reassembled above the cable, the electric telescopic rod 6408 drives the insertion rod 6410 to insert into the insertion hole on the semi-ring sliding frame 6203. At this time, the arc-shaped housing 6401 can move with the semi-ring sliding frame 6203. At this time, the insulating tape output assembly 63 and the auxiliary clamping assembly 64 are horizontally symmetrically arranged. The third micro motor 6205 drives the semi-ring sliding frame 6203 to rotate 90 degrees, so that the insulating tape output assembly 63 is located directly above the auxiliary clamping assembly 64, and the insulating tape is output through the conveying roller group. One end of the insulating tape moves vertically into the clamping groove 6402 under the action of gravity. At this time, by controlling the change of the positive and negative poles of the first semi-circular power supply component 71, the second electromagnet 6404 drives the second permanent magnet 6405 to move toward the position of the second electromagnet 6404. The moving clamp 6406 moves with the second permanent magnet 6405. When the insulating tape moves between the moving clamp 6406 and the fixed clamp 6407, the positive and negative poles of the first semi-circular power supply component 71 are changed again, so that the second electromagnet 6404 drives the second permanent magnet 6405 to move away from the second electromagnet 6404, and the moving clamp 6406 and the fixed clamp 6407 re-limit and clamp the insulating tape. When the plug 6410 is disengaged from the plug hole, the friction provided by the damping layer to the fan-shaped terminal plate 6409 can prevent the arc-shaped housing 6401 from being dragged by the pulling force of the insulating tape.

[0052] The above description of this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
