Description

Technical Field

[0001] The present invention relates to the technical field of power equipment fault monitoring, and more specifically, the present invention relates to a fault monitoring device for power equipment in a distribution network. Background Art

[0002] As a core component of the power system, the safe and stable operation of high-voltage transmission lines is directly related to the reliability of the power grid. During use, the vibration or galloping of the wire due to long-term exposure to wind will cause fatigue cracks at the parts where the material stress on the wire is concentrated. Therefore, the inspection and monitoring of high-voltage transmission lines are essential maintenance means. Traditional inspection means mainly include manual inspection, unmanned aerial vehicle (UAV) inspection, and fixed monitoring devices.

[0003] However, traditional manual inspection relies on personnel climbing, which is not only inefficient but also poses a high safety risk; UAV inspection is limited by factors such as battery life and signal strength and is difficult to operate stably for a long time. Fixed monitoring devices are usually installed at specific positions on iron towers or wires, with a limited coverage area. Especially in the case of a large span between two electric towers (such as two electric towers installed on both sides of a mountain valley), it is impossible to achieve full-line dynamic monitoring of the wire, resulting in difficulties in timely troubleshooting of high-voltage line faults and thus affecting normal power transmission operations. Summary of the Invention

Detailed implementation manners

[0030] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0031] Refer to the attached instructions Figure 1 and Figure 2 In the present invention, there are four sub-conductors 1, and the spacer dampers 2 corresponding thereto have four connection ends. By arranging a plurality of spacer dampers 2 on the spacer damper 2 at a preset spacing, the four sub-conductors 1 can be kept in a square distribution state at any stage.

[0032] Embodiment 1 Refer to the attached instructions Figures 1 to 13 A fault monitoring device for power equipment in a distribution network includes: a plurality of sub-conductors 1, and the same spacer damper 2 is arranged on the plurality of sub-conductors 1. The spacer damper 2 is used to evenly separate the plurality of sub-conductors 1 into a regular polygon distribution; It should be noted that according to factors such as voltage level, environmental conditions, and power transmission requirements, most high-voltage lines in our country will adopt the design of multi-split conductors. Among them, ultra-high voltage (≥800 kV) usually adopts eight-split or ten-split conductors, extra-high voltage (500 - 750 kV) usually adopts four to eight-split conductors, and high voltage (220 - 330 kV) usually adopts two to four-split conductors. The four-split conductor design belongs to the most common high-voltage line design; Furthermore, in order to prevent the sub-conductors 1 from colliding or winding with each other and suppressing aeolian vibration and sub-span oscillation, the distance between two adjacent sub-conductors 1 usually needs to be kept at 400 - 600 mm. For example, the distance between two adjacent sub-conductors 1 in a 500 kV line with a four-split conductor design is usually 450 mm, and the multi-split conductor design usually makes multiple sub-conductors 1 keep a regular polygon distribution, such as a square, a regular hexagon, and a regular octagon, etc.

[0033] A fault monitoring mechanism 3 is arranged on the sub-conductor 1. The fault monitoring mechanism 3 includes two semi-circular arc-shaped guide rails 31 arranged symmetrically up and down, and the two semi-circular arc-shaped guide rails 31 are hinged. The semi-circular arc-shaped guide rails 31 enclose a circular ring-shaped guide rail, and the semi-circular arc-shaped guide rails 31 are arranged outside the sub-conductor 1. A defect detection component 33 is arranged on the semi-circular arc-shaped guide rail 31. The defect detection component 33 includes a plurality of traveling units 331. The traveling unit 331 includes a mounting plate one 3311 that moves along the circumferential direction of the semi-circular arc-shaped guide rail 31. A support unit 332 is arranged on the mounting plate one 3311. The support unit 332 includes a mounting plate two 3321 mounted on the mounting plate one 3311. A self-propelled wheel two 3323 is arranged on the mounting plate two 3321. The self-propelled wheel two 3323 moves along the length direction of the corresponding sub-conductor 1; It should be noted that a limit connecting member (not marked in the attached drawings), such as a plug-slot mechanism, can be provided on the side where the movable ends of the two semi-circular arc-shaped guide rails 31 are close to each other. The movement of the defect detection component 33 can be controlled by a PLC, which is a well-known and mature technology for those skilled in the art and will not be elaborated in this embodiment; An X-ray flaw detection unit 333 is provided on the second mounting plate 3321. The X-ray flaw detection unit 333 includes a micro X-ray generator 3331 and an imaging plate 3334 provided on the second mounting plate 3321 close to one side of the corresponding sub-conductor 1. The output end of the micro X-ray generator 3331 faces the corresponding sub-conductor 1, and the imaging plate 3334 is located on the side of the corresponding sub-conductor 1 away from the micro X-ray generator 3331.

[0034] It should be noted that during flaw detection, the output end of the micro X-ray generator 3331 is perpendicular to the imaging plate 3334, and the imaging plate 3334 will move to a position closer to the sub-conductor 1. For example, the distance between the two is maintained at about 5 cm to avoid collision while ensuring good imaging effects.

[0035] In this embodiment, the implementation scenario is as follows: When installing the fault monitoring device, power workers climb on the electric tower to carry the device up. For example, the power workers can first climb up the tower, and then hoist the device by means of a rope and pulley, or use equipment such as a drone to hoist the device up under the premise of ensuring safety. When installing the defect detection component 33, the semi-circular arc-shaped guide rail 31 and the semi-circular arc-shaped rack 32 are synchronously opened by controlling the fourth driving component 344, and then the defect detection component 33 is moved to one side of the sub-conductor 1. Then, through manual traction or in cooperation with corresponding traction tools, the opened side of the semi-circular arc-shaped guide rail 31 is oriented towards the sub-conductor 1 and moved horizontally towards the direction close to the sub-conductor 1 until all the sub-conductors 1 are surrounded by the semi-circular arc-shaped guide rail 31, and then the fourth driving component 344 can be controlled to close; In the initial state, all the second self-propelled wheels 3323 and the imaging plate 3334 will be in a retracted state to avoid interfering with the installation work. When the semi-circular arc-shaped guide rail 31 moves to the preset position, all the first mounting plates 3311 are controlled to move to the preset position. Then, the imaging plate 3334 is first extended to the side beyond the corresponding sub-conductor 1 without interference, and then the position of the first mounting plate 3311 is adjusted. Next, the second self-propelled wheels 3323 are extended so that they are in close contact with the corresponding sub-conductor 1. When all the second self-propelled wheels 3323 are in close contact with the corresponding sub-conductor 1 at a preset angle, the generated clamping force can support the entire defect detection component 33. At this time, the installation of the defect detection component 33 is completed.

[0036] Embodiment 2 Based on Embodiment 1, referring to the attached drawings of the specificationFigures 1 to 13 , this embodiment also provides a fault monitoring mechanism 3 that can move along the length direction of the sub-conductor 1 on the sub-conductor 1 and synchronously detect defects in all sub-conductors 1, so as to solve the problem in the prior art that it is difficult to perform stable full-line dynamic fault monitoring on the conductor by several high-voltage line fault monitoring means such as manual inspection, drone inspection, and fixed monitoring devices, resulting in difficulty in timely eliminating high-voltage line faults, and further affecting normal power transmission operations.

[0037] For example, manual inspection can only be carried out by staff to visually inspect the sub-conductor 1. Even with the cooperation of a flaw detection device similar to the X-ray flaw detection unit 333, the staff still needs to climb and move on the sub-conductor 1 for a long time, with a high safety risk; while drone inspection is affected by factors such as battery life, signal, and even weather conditions (such as strong wind weather), and the normal working time window is very limited; the fixed monitoring device is limited by the installation location. It is very difficult to cover the entire range of the sub-conductor 1 in the case of a large span between two electric towers (such as two electric towers installed on both sides of a mountain valley). If the installation density is forcibly increased, factors such as cost and whether there are enough suitable installation locations need to be comprehensively considered.

[0038] A semi-circular arc-shaped guide rail 31 is provided with a semi-circular arc-shaped rack 32. The semi-circular arc-shaped racks 32 are enclosed to form a circular rack. A driving component one 3312 is provided on the mounting plate one 3311. The output end of the driving component one 3312 is provided with a traveling gear 3313. The traveling gear 3313 meshes with the semi-circular arc-shaped rack 32. A plurality of guide wheels 3314 are provided on the mounting plate one 3311. The guide wheels 3314 are adapted to the semi-circular arc-shaped guide rail 31.

[0039] It should be noted that the driving component one 3312 is a motor. After the semi-circular arc-shaped racks 32 are enclosed to form a circular rack, on the premise of not being interfered by the sub-conductor 1 or the spacer 2, the defect detection component 33 can move arbitrarily on the semi-circular arc-shaped rack 32 under the control of the PLC, which is a well-known mature technology in the art and will not be elaborated in this embodiment.

[0040] A clamping and opening component 34 is provided on the semi-circular arc-shaped rack 32. The clamping and opening component 34 includes two hinge plates 341 respectively fixedly installed on the corresponding semi-circular arc-shaped racks 32, and the two hinge plates 341 are arranged in a staggered manner. The two hinge plates 341 are rotatably connected to each other by the same hinge shaft 342. A pull rod 343 is provided on the hinge plate 341. A driving component four 344 is provided between the two pull rods 343. The fixed end and the output end of the driving component four 344 are respectively rotatable with the corresponding pull rod 343.

[0041] It should be noted that the fourth driving component 344 is an electric push rod. When controlling the opening and closing of the two semi-circular racks 32 through the fourth driving component 344, it can be assisted by the staff to make the semi-circular racks 32 move in a horizontal state.

[0042] A second driving component 3322 is provided on the second mounting plate 3321. The second self-propelled wheel 3323 is fixedly connected to the output end of the corresponding second driving component 3322. A guide rod 3324 is provided on the side of the second self-propelled wheel 3323 close to the second mounting plate 3321. The guide rod 3324 is slidably connected to the second mounting plate 3321. The second self-propelled wheel 3323 is adapted to the corresponding sub-wire 1.

[0043] It should be noted that the second driving component 3322 is an electric push rod. The second self-propelled wheel 3323 has a power source, such as an electric self-propelled wheel, with its own driving source.

[0044] A third driving component 3332 is provided on the second mounting plate 3321. A connecting frame 3333 is provided at the output end of the third driving component 3332. The connecting frame 3333 is fixedly connected to the corresponding imaging plate 3334.

[0045] It should be noted that the third driving component 3332 is an electric push rod. A guiding device can also be provided on the micro X-ray generator 3331 to improve the control accuracy of the imaging plate 3334, such as a guide rail slider mechanism; Furthermore, an angle adjustment mechanism can also be provided between the connecting frame 3333 and the imaging plate 3334 to further improve the flaw detection accuracy of this assembly, so that the micro X-ray generator 3331 can detect the sub-wire 1 from different angles of the sub-wire 1. This is a well-known and mature technology in the field and will not be elaborated in this embodiment.

[0046] In this embodiment, the implementation scenario is specifically as follows: When detecting the sub-wire 1 for flaws, by controlling the micro X-ray generator 3331 to emit X-rays to the corresponding sub-wire 1, the internal imaging of the sub-wire 1 can be obtained on the imaging plate 3334, so as to accurately detect possible defects such as cracks on the surface and inside of the sub-wire 1. Each time a shot is taken, the defect detection component 33 stops moving on the sub-wire 1 to maintain imaging clarity. After obtaining the imaging information, move the micro X-ray generator 3331 within the maximum detection range for the next shot detection, and cycle in turn until all sub-wires 1 are comprehensively detected. The collected imaging information can be transmitted to the receiving end of the ground staff through remote signal transmission technology, or can be temporarily stored in the corresponding storage device (such as a hard disk). This is a well-known and mature technology in the field and will not be elaborated in this embodiment.

[0047] Embodiment 3 Based on Embodiment 2, referring to the accompanying drawings of the specification Figures 1 to 13 , this embodiment further provides an obstacle-crossing mechanism 4 that can additionally provide a traction force for the fault monitoring mechanism 3 to move along the length direction of the sub-conductor 1 on the sub-conductor 1, and enable the fault monitoring mechanism 3 to cross the obstacles generated by some necessary components provided on the sub-conductor 1; to solve the problem in the prior art that when the defect detection component 33 encounters components with a certain height such as spacer dampers 2 or suspension clamps, it cannot cross the obstacles.

[0048] For example, in the prior art, when the fault monitoring mechanism 3 moves on the sub-conductor 1 and encounters a spacer damper 2, causing the second self-propelled wheel 3323 to be unable to cross, and thus unable to comprehensively detect the defects of the sub-conductor 1, manually moving the position by the staff will significantly increase the safety hazards of the staff. And when using a drone to hoist and cross the obstacle, not only the battery life of the drone needs to be considered, but also in the high-altitude environment, due to the influence of factors such as distance and wind force, it is very difficult to accurately complete the re-docking work after the second self-propelled wheel 3323 leaves the sub-conductor 1. Not only is the efficiency low, but the operation is also very difficult.

[0049] An obstacle-crossing mechanism 4 is provided on the sub-conductor 1. The obstacle-crossing mechanism 4 includes two vertically arranged linear drive components 41, and the linear drive components 41 are located outside the sub-conductor 1. Two movable parts are provided on the output ends of the linear drive components 41, and the two movable parts move synchronously and in opposite directions. Clamping plates 42 are provided on the sides of the movable parts of the two linear drive components 41 close to the sub-conductor 1. The clamping plates 42 are horizontally arranged, and the two clamping plates 42 are respectively located on the upper and lower sides of the spacer damper 2. A first self-propelled wheel 43 is provided on the side of the clamping plate 42 close to the sub-conductor 1. The first self-propelled wheel 43 moves along the length direction of the corresponding sub-conductor 1, and the first self-propelled wheel 43 is adapted to the corresponding sub-conductor 1.

[0050] It should be noted that the linear drive component 41 is a screw motor, and the screw part of the linear drive component 41 is designed as a symmetrically arranged bidirectional screw, so that the two clamping plates 42 installed on the same linear drive component 41 can move synchronously and in opposite directions. The first self-propelled wheel 43 has a power source, such as an electric self-propelled wheel, with its own drive source; Furthermore, the first self-propelled wheel 43 and the clamping plate 42 are detachably installed. For example, they can be connected by bolts or other quick-release parts. By pre-aligning the installation position of the first self-propelled wheel 43 with the sub-conductor 1, when the two clamping plates 42 on the same linear drive component 41 move synchronously and approach each other, the first self-propelled wheels 43 are respectively closely attached to the corresponding sub-conductor 1 from the upper and lower sides, so as to achieve the effect that the whole obstacle-crossing mechanism 4 can be stably installed on the sub-conductor 1 and move.

[0051] On one side of the two linear drive components 41 far away from the sub-conductor 1, a flipping component 44 is provided. The flipping component 44 includes two mounting brackets 441 respectively mounted on the corresponding linear drive components 41. A fifth drive component 442 is provided on the mounting bracket 441. A rotating shaft 443 is provided on the output shaft of the fifth drive component 442. A flipping gear 444 is provided on the rotating shaft 443. The two flipping gears 444 are meshed with each other. A same connecting rod 445 is rotatably sleeved between the two rotating shafts 443.

[0052] It should be noted that the fifth drive component 442 is a motor, and the fifth drive components 442 respectively mounted on the two linear drive components 41 are arranged at staggered positions to avoid possible interference during flipping.

[0053] Refer to the attached drawings of the specification Figure 10 As shown in the figure, the two linear drive components 41 are both on the left side of the spacer 2. When the linear drive component 41 needs to cross the spacer 2, first, the two clamping plates 42 on the relatively left linear drive component 41 among the two linear drive components 41 are synchronously moved away from each other, so as to release its connection with the sub-conductor 1. Then, by starting the clockwise rotation of the flipping gear 444 mounted on the relatively right linear drive component 41 among the two linear drive components 41, at this time, under the action of the connecting rod 445, the relatively left linear drive component 41 among the two linear drive components 41 rotates counterclockwise by 360 degrees with the rotating shaft 443 on the relatively right linear drive component 41 as the rotating shaft, so that the relatively left linear drive component 41 among the two linear drive components 41 crosses to the right side of the spacer 2. At this time, the originally relatively right linear drive component 41 among the two linear drive components 41 is still on the left side of the spacer 2, while the originally relatively left linear drive component 41 among the two linear drive components 41 moves to the right side of the spacer 2. At this time, the linear drive component 41 that has already been on the right side of the spacer 2 is fixed to the sub-conductor 1 again by operating to reset the two clamping plates 42. After it is fixed, the flipping gear 444 on the linear drive component 41 that has already been on the right side of the spacer 2 is rotated clockwise. At this time, under the action of the connecting piece, the linear drive component 41 still on the left side of the spacer 2 crosses to the right side of the spacer 2 according to the same operation as described above, that is, it is equivalent to the entire obstacle-crossing mechanism 4 being translated from the left side of the spacer 2 to the right side of the spacer 2, so as to achieve the effect of the entire device crossing the spacer 2; Further, when performing this operation, the fault monitoring mechanism 3 and the obstacle-crossing mechanism 4 are in a separated state, and the fault monitoring mechanism 3 will retreat a certain distance to reserve enough flipping space for the obstacle-crossing mechanism 4.

[0054] A number of connection and fixing components 45 are provided on each of the two clamping plates 42 closest to the semi-circular rack 32. On one side of the second mounting plate 3321 close to the corresponding connection and fixing component 45, a magnetic attraction support rod 3335 is provided, and the magnetic attraction support rod 3335 is adapted to the corresponding connection and fixing component 45.

[0055] It should be noted that after the obstacle-crossing mechanism 4 flips from the left side of the spacer 2 to the right side of the spacer 2, the fault monitoring mechanism 3 is moved in the direction close to the obstacle-crossing mechanism 4, and the magnetic attraction support rod 3335 is inserted into the corresponding connection and fixing component 45, and then energized to tightly connect and fix the two, so that the obstacle-crossing mechanism 4 can support the entire fault monitoring mechanism 3. At this time, by resetting all the second self-propelled wheels 3323 and the imaging plate 3334 to the initial state, the entire fault monitoring mechanism 3 can avoid the spacer 2. At this time, it is equivalent to that the entire fault monitoring mechanism 3 is suspended and supported by the cooperation of the magnetic attraction support rod 3335 and the connection and fixing component 45. Then, by moving the entire obstacle-crossing mechanism 4 to the right, the fault monitoring mechanism 3 can synchronously cross the spacer 2, and the obstacle-crossing operation of the fault monitoring mechanism 3 can be completed. Then, the entire fault monitoring mechanism 3 is fixed on the sub-conductor 1 again, and the imaging plate 3334 is moved to the detection station again, so as to continue to detect the defects of the subsequent sub-conductor 1; Furthermore, before and after the obstacle-crossing operation, it is necessary to fully detect the positions on both sides of the spacer 2 to avoid missing undetected areas. In the subsequent obstacle-free area on the sub-conductor 1, the fault monitoring mechanism 3 and the obstacle-crossing mechanism 4 are connected into one body through the connection and fixing component 45 and the magnetic attraction support rod 3335, so as to further improve the stability of the equipment movement, and thus enhance the wind resistance, earthquake resistance and other performances of the entire equipment.

[0056] The minimum distance between the two linear drive components 41 is greater than the maximum thickness of the spacer 2.

[0057] It should be noted that the minimum distance between the two linear drive components 41 and the clamping plates 42 respectively installed on the two linear drive components 41 is greater than the maximum thickness of the spacer 2, and by adjusting the specifications of the flipping gear 444 and the connecting rod 445, the obstacle-crossing mechanism 4 can cross more types of obstacles.

[0058] Hoisting rings are provided on one side of the clamping plate 42 and the second mounting plate 3321 away from the sub-conductor 1.

[0059] It should be noted that the setting of the hoisting ring can facilitate the hoisting of the equipment.

[0060] The above-described embodiments merely represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
