Description

TECHNICAL FIELD

[0001] The present application relates to the field of power transmission and distribution, in particular to a safe dismounting device for an inductive power taking device and a power transmission line fault point searching system. BACKGROUND

[0002] An overhead power transmission line refers to a power transmission facility erected on the ground by poles and towers. When a fault occurs in the power transmission line, the power supply company needs to quickly determine the fault point and arrange for maintenance in time so as to not affect people's production and life.

[0003] Taking the first inspection team as an example, a unit statistically recorded the fault point searching time of each time in a station from May to August in 2015, as shown in Table 1. Figure 1 According to the statistical data, it can be known that the number of times that the fault searching time is greater than 210 minutes from May to August in 2015 is 17, and the overhead power transmission line fault point searching time requirement of the unit is 210 minutes, so the number of times that does not meet the requirement accounts for 89.5% of the total number of times in four months.

[0004] Through investigation and analysis by relevant personnel, it is determined that the reasons for the above long time are: insufficient training depth of line searching personnel, insufficient information channel, long preparation time of corresponding tools required for line searching, long analysis time of current recording graph, slow image transmission in special areas, and no establishment of a quick contact mechanism.

[0005] For the human subjective factor of insufficient training depth, the relevant unit can improve it by inviting experts to carry out training, conducting examination and strengthening learning, but for the influence caused by natural factors and insufficient existing technical means, it cannot be solved at present, for example: slow image transmission in special areas.

[0006] In the areas where residents frequently move in cities and towns, the fault of the power transmission and distribution cable can be monitored all day long by arranging cameras nearby to obtain the live images on site in a remote manner, so as to efficiently find the fault point and arrange for maintenance work.

[0007] However, the power transmission and distribution cable often passes through mountainous areas and other sparsely populated areas. In such special areas, because of the lack of civil facilities, there is often a lack of, or even no, low-voltage civil power supply network, only high-voltage / ultra-high-voltage power transmission network, which leads to the fact that the camera and other low-voltage equipment cannot be powered, i.e. the relevant unit cannot arrange cameras to monitor the cable in the special area all day long and obtain images to troubleshoot the fault. After the fault is found by using the power distribution network, it is necessary to estimate the fault range, arrange for on-site inspection and evidence collection, and then determine how to carry out maintenance work according to the on-site situation, which leads to a long time consumption.

[0008] Furthermore, if the high-voltage / ultra-high-voltage transmission lines are modified, and the modifications are carried out in large areas, just to power the cameras, this is not only difficult to implement but also has a very low cost-effectiveness. At the same time, due to the characteristics of high-voltage / ultra-high-voltage power transmission, more safety hazards will be added during maintenance. Therefore, this application proposes a new technical solution. Summary of the Invention

The fixed pulley is rotatably connected to the machine body, and the end of the linkage rope away from the guide rod passes out of the machine body.

[0019] The linkage rod is located outside the machine body and is rotatably connected to the machine body at a non-end position. One end of the linkage rod is fixed to the linkage rope, and the other end extends above the flexible belt.

[0030] Obtain the battery pack power of the inductive power supply module;

[0031] If the detection value fed back by the current sampling unit indicates that the power transmission line is open and the battery pack's charge is less than the preset safety lower limit, then at least the rope reel should be controlled to release the upper and lower ropes.

Detailed Implementation

[0045] The following is in conjunction with the appendix Figures 2-9 This application will be described in further detail.

[0046] This application discloses a safe disassembly and assembly device for inductive power supply equipment.

[0047] Reference Figure 2 and Figure 3 The safety disassembly and assembly device for inductive power supply equipment includes an inductive power supply module 1 and an installation machine. The inductive power supply module 1 refers to a functional module that draws power from the transmission (conductor) in the form of current inductance. The power supply principle and structure are similar to those of a current transformer, and an open-type current sensor is preferred to better cooperate with other subsequent settings. After power is drawn, it is introduced into a rectifier and filter unit through a wire, and then sent to a power regulation unit such as a DC-DC converter to obtain a suitable current for use.

[0048] The inductive power supply module 1 includes a base 11 and an inductive component 12. The base 11 can be a hollow structure with a metal shielding mesh fixed along the inner wall to reduce external magnetic field interference. The base 11 includes two interlocking bowl structures, which are fixed by bolts, clamps or cages. The aforementioned rectifier and filter unit can be installed inside the base 11.

[0049] In this embodiment, a battery pack is also installed in the base 11 to store part of the acquired electrical energy for use as a backup power source during special periods; the battery pack is connected to a matching charging manager (circuit) to reasonably control the electrical energy replenished from the power regulation unit and prevent overcharging, etc.

[0050] The sensing component 12 includes two side-by-side structural blocks 121. The opposing sides of the two structural blocks 121 are recessed to form sub-slots, which are semi-circular. When the two structural blocks 121 are closed together, the two sub-slots merge into a circle, allowing power transmission lines to pass through. The structural blocks 121 are slidably connected to the base 11, with the sliding direction parallel to the arrangement direction of the two structural blocks 121. At least one structural block 121 contains a built-in coil for inductive power extraction.

[0051] Reference Figure 4 , Figure 5 and Figure 6 The aforementioned installation machine includes a body 2, an upper cable 3, a lower cable 4, a linkage upper cable mechanism 5, a controller 6, and a locking mechanism 7. In this embodiment, the body 2 is a flat box formed by splicing and fixing plate structures, and the box is vertical. The aforementioned base 11 is fixed to the side wall of the body 2 by connecting rods, etc., so as to realize the installation and removal of the inductive power extraction module 1 on the power transmission line.

[0052] The body 2 is provided with a hanging groove. The groove structure after the hanging groove and the two sub-slots are spliced ​​together is on the same central axis. The two ends of the hanging groove are open and the entrance and exit are opened on one side. One end of the upper rope 3 is fixed to the body 2 and the connection point is located above the hanging groove. There can be two upper ropes 3 and they are distributed along the length of the hanging groove.

[0053] The aforementioned linkage mechanism 5 is installed on the body 2 and is used to drive the two structural blocks 121 to close towards each other when the hanging trough falls onto the power transmission line. The locking mechanism 7 is installed on the body 2 and is used to lock the entrance and exit of the hanging trough. The locking mechanism 7 is electrically connected to the controller 6.

[0054] The power circuits of controller 6 and locking mechanism 7 are electrically connected to inductive power supply module 1, for example, by drawing power from the battery pack in base 11 via a wire. Controller 6 is configured to output a locking control command matching the locking mechanism 7 after power-on.

[0055] The aforementioned lower cord 4 is movably connected to the body 2 and is used to drive the linkage upper cord mechanism 5 to restore the separation state of the two structural blocks 121 and trigger the controller 6 to output the restoration control command of the matching locking mechanism 7.

[0056] Usage process:

[0057] 1) The staff tied a small stone to the free end of the upper rope 3 and threw the stone to make the upper rope 3 go around the power line; or, they used a long pole to go around the free end of the upper rope 3 around the power line; or, they used a drone to take the free end of the upper rope 3 around the power line.

[0058] 2) The staff holds the free end of the upper rope 3 and pulls it down. The upper rope 3 drives the body 2 of the installation machine to move upward, and the body 2 drives the induction power extraction module 1 to move upward. As the body 2 approaches the power transmission line, the power transmission line will then enter the hanging groove from the side opening of the hanging groove. During this process, the power transmission line is located above the two structural blocks 121 and enters from the gap opening between the two structural blocks 121.

[0059] 3) When the power transmission line enters the hanging slot of the machine body 2, the staff releases the upper rope 3; then, the linkage upper mechanism 5 is triggered, driving the two structural blocks 121 to close towards each other; the inductive power module 1 works to draw power to supply power to the controller 6 and the locking mechanism 7, and then the locking mechanism 7 closes the entrance and exit of the hanging slot to prevent the installation machine from falling off the power transmission line.

[0060] 4) When it is necessary to disassemble the installation machine, pull the lower cord 4 to drive the linkage upper cord mechanism 5 to restore the separation of the two structural blocks 121 and trigger the controller 6 to output the restoration control command of the matching locking mechanism 7, so that the two structural blocks 121 and the hanging slot can be reopened so that the installation machine and the inductive power supply module 1 can be removed.

[0061] It is understandable that the upper cord 3, the machine body 2, and the lower cord 4 should be made of insulating materials to prevent electric shock; for example, nylon cord or plastic shell.

[0062] Based on the above settings, staff can draw power from power transmission lines without approaching or touching them, thus helping relevant personnel and units to conduct preliminary work for locating power transmission faults more safely. Moreover, during installation and disassembly, simply pull the upper rope 3 and the lower rope 4, making the operation relatively convenient and efficient.

[0063] Reference Figure 3 In one embodiment of this application, a slide rail is fixed on the base 11, and the structural block 121 is slidably connected to the slide rail; the base 11 is recessed on the side of the slide rail, and a flexible traction belt is provided between the structural blocks 121, with the two ends of the flexible traction belt respectively fixed to the opposite sides of the structural blocks 121.

[0064] ReferenceFigure 4 and Figure 7 The linkage mechanism 5 includes a contact plate 51, a linkage rope, a linkage rod 52, and a fixed pulley. The contact plate 51 is located at the top of the hanging groove and has an arc shape at the end to fit the upper inner wall of the hanging groove. The power transmission line is placed in the hanging groove and abuts against the contact plate 51. A guide rod is fixed at the top of the contact plate 51. The guide rod is vertically inserted through the machine body 2 and is slidably connected.

[0065] There are three fixed pulleys, with one pulley near the top of the hanging groove. The linkage rope passes around the bottom of this fixed pulley and is fixed to the upper end of the guide rod. Another fixed pulley is called the reversing pulley. The reversing pulley is located above and to the side of the first fixed pulley, and the end of the linkage rope away from the guide rod passes around the upper part of the reversing pulley. Another fixed pulley is located below the first two fixed pulleys, and the end of the linkage rope away from the guide rod passes around it from below. The fixed pulleys are rotatably connected to the machine body 2, and the end of the linkage rope away from the guide rod passes out of the machine body 2.

[0066] A structural frame is fixed on the outer wall of the body 2 near the inductive power extraction module 1. The non-end position of the linkage rod 52 is rotatably connected to the structural frame via a rotating shaft, and one end is fixed to the end of the linkage rope away from the guide rod, while the other end extends to the upper part of the flexible belt. In this embodiment, the linkage rod 52 is a composite structure, with at least a portion of its structure located in front of the hanging groove and extending in a direction away from the hanging groove, so as to contact the flexible belt.

[0067] Usage process: When the power transmission line is in the hanging groove, the staff releases the upper rope 3, and the machine body 2 falls on the power transmission line. During this process, the contact plate 51 stops on the power transmission line, and the machine body 2 continues to move downward, that is, the guide rod moves upward. The movement of the guide rod pulls the linkage rope, and under the guidance of the fixed pulley, it pulls the linkage rod 52 away from the end of the inductive power extraction module 1. Correspondingly, the other end of the linkage rod 52 swings downward and drives the flexible belt to move downward. The downward movement of the flexible belt pulls the two structural blocks 121 closer to each other and closes them together.

[0068] According to the above settings, after the staff loosens the upper rope 3, the machine body 2 falls down, which can drive the inductive power-taking module 1 to close, thus making the installation relatively convenient.

[0069] It should be noted that if you want the two structural blocks 121 to automatically separate when the flexible belt is not pressed down by the linkage rod 52, a return spring 122 can be installed at the bottom of the structural block 121 on the side of the slide rail. One end of the return spring 122 is fixed to the plate extending from the bottom of the structural block 121, and the other end is fixed to the base 11. Under the action of the return spring 122, the two structural blocks 121 separate.

[0070] Reference Figure 7In one embodiment of this application, the locking mechanism 7 includes a sealing rod 71 and an electric push rod 72. The sealing rod 71 is vertically slidably connected to the body 2 and its upper end extends into the hanging groove. There are multiple sealing rods 71 ​​arranged along the length of the hanging groove. The electric push rod 72 is installed inside the body 2 and is vertically arranged. The telescopic rod end of the electric push rod 72 fixes the sealing rod 71 for pushing it up to close the entrance and exit of the hanging groove. It can be understood that multiple sealing rods 71 ​​can be connected to each other at the bottom and top by a linkage or other structure, so that one electric push rod 72 can drive multiple sealing rods 71.

[0071] After closing the hanging trough using the above-described configuration, although the power transmission line no longer detaches from it, there is a chance that a strong wind could cause the power transmission line and the upper structure of the hanging trough to temporarily separate. This would affect inductive power extraction, as described in the previous embodiment. Therefore, this application further specifies:

[0072] A limiting ring is fixed to the side wall of the sealing rod 71, and a limiting plate 73 is provided above the sealing rod 71. The limiting plate 73 has a through hole that is adapted to the diameter of the sealing rod 71 and is smaller than the diameter of the limiting ring. The limiting plate 73 can be made of elastic rubber, which is used to reduce the effective space of the hanging slot while the sealing rod 71 rises to close the entrance and exit of the hanging slot, thereby restraining the power transmission line.

[0073] Understandably, the top of the sealing rod 71 is fixed with an anti-detachment circular plate, the diameter of which is larger than the through hole on the limiting plate 73, to prevent strong winds from blowing the limiting plate 73 away.

[0074] Reference Figure 4 and Figure 7 In one embodiment of this application, a lower wire window is provided on the side wall of the body 2 away from the hanging slot. An inner plate 20 is vertically slidably connected to the inner side of the lower wire window. A tension spring 21 is fixed to the side of the inner plate 20 facing upwards. The tension spring 21 is vertical and its upper end is fixed to the inner wall of the body 2 so that the inner plate 20 always tends to face upwards. A lever 41 is fixed to the outer side of the inner plate 20. The lever 41 extends out from the lower wire window and is initially located at the upper part of the lower wire window. The lower wire rope 4 is connected to the lever 41 (through hole).

[0075] An inner frame is fixed on the side of the inner plate 20 opposite to the lower window, and the aforementioned reversing wheel is rotatably connected to the inner frame.

[0076] According to the above settings, if the user pulls down the lower cord 4, the lower cord 4 will drive the inner plate 20 to move downward. The inner plate 20 moving downward will drive the reversing wheel to move downward through the inner frame. As the reversing wheel moves downward, the linkage rope will loosen and there will be no force to pull the linkage rod 52 upward. At this time, the two structural blocks 121 will separate under the action of the reset spring 122, that is, the inductive power supply module 1 will be turned on.

[0077] At this time, if the hanging slot is not equipped with the sealing rod 71, that is, the entrance and exit of the hanging slot are open, then the machine body 2 and the induction power supply module 1 can be removed from the power transmission line.

[0078] It should be noted that after the reversing wheel moves down and then up again, its narrow width during this process may cause the linkage rope to come off. Therefore, the reversing wheel is widened axially to form a long shaft structure, which is called the reversing shaft 53.

[0079] Reference Figure 7 In another embodiment of this application, considering the case where a sealing rod 71 is provided, this application is configured as follows:

[0080] A self-reset button 22 is provided inside the body 2. The self-reset button 22 is electrically connected to the controller 6, which can be integrated into the body 2. The self-reset button 22 is located on the side of the inner plate 20. The width of the inner plate 20 is gradually changing from top to bottom. The pressing part of the self-reset button 22 is located on the moving path of the wide side of the inner plate 20. That is, when the lower cord 4 is pulled down and drives the lever 41 to move down, the internal part moves down synchronously and presses the self-reset button 22 during the movement to generate a signal to return to the controller 6.

[0081] Based on the above, the controller 6 is configured to: if it receives a signal when the self-reset button 22 is pressed, output a recovery control command for the matching locking mechanism 7, that is, a control command for controlling the retraction of the electric push rod 72.

[0082] According to the above settings, when it is necessary to disassemble the installation machine, simply pull down the lower cord 4 to retract the electric push rod 72, so that the limiting plate 73 can be pushed down and the sealing rod 71 can be retracted to reopen the entrance and exit of the hanging slot.

[0083] Reference Figure 6 and Figure 7 In another embodiment of this application, considering that the downward bending structure of the upper edge of the slot inlet and outlet would obstruct the direct horizontal movement of the power transmission line out of the slot, thus requiring the use of tools such as long poles to remove the installation machine, this application further configures it as follows:

[0084] The fixed pulley at the end closest to the guide rod is axially widened to form a multi-functional guide shaft 54. The upper edge structure of the hanging slot inlet and outlet is an independent upper edge plate 23 that is separate from the body 2. The upper end of the upper edge plate 23 is rotatably connected to the body 2 through the side pivot.

[0085] An open pull rope is fixed to the lower part of the outer wall of the upper edge plate 23. The open pull rope passes through the body 2, goes around the upper part of the multi-functional guide shaft 54, and the other end is fixed downward to the lower end of the inner plate 20.

[0086] According to the above settings, when the lower cord 4 pulls the inner plate 20 downward, the inner plate 20 moves downward and pulls the upper edge plate 23 outward through the open cord to open the upper part of the hanging groove, so that the power transmission line can be moved horizontally out of the hanging groove, making it convenient to remove the installation machine from the power transmission line.

[0087] Understandably, the length of the pull rope is preferably set so that it starts pulling the upper edge plate 23 only in the latter half of the downward movement of the inner plate 20. This is because its rotation is small, and also to ensure that the hanging slot is only opened when the actual offline installation machine is needed.

[0088] Reference Figure 7 and Figure 8 In one embodiment of this application, considering that the above-mentioned arrangement would cause the upper rope 3 and lower rope 4 to hang down after the installation machine is installed on the power transmission line, and that if this is not addressed, the rope structure may become entangled in nearby objects or facilities, leading to safety hazards, this application further sets the following:

[0089] A rope winder 8 is installed inside the body 2. The rope winder 8 includes a (miniature) servo motor 81 and a rope reel 82 fixed to the output shaft of the servo motor 81. Each upper rope 3 and lower rope 4 is matched with a rope winder 8, and one end of the rope structure is fixed to the rope reel 82. The servo motor 81 is electrically connected to the controller 6, which is configured as follows:

[0090] If the locking mechanism 7 locks in place, that is, the electric push rod 72 extends, it outputs a rope winding control command to match the servo motor 81, that is, the servo motor 81 drives the rope reel 82 to rotate, so as to wind up the upper rope 3 and the lower rope 4.

[0091] Understandably, the winder 8 corresponding to the lower rope 4 should be fixed to the back of the inner plate 20 so that the inner plate 20 can be pulled down.

[0092] Under the above configuration, a wireless communication unit can be integrated inside the machine body 2. The wireless communication unit can be a 3G / 4G communication unit. The wireless communication unit is electrically connected to the controller 6 so that after the upper rope 3 and the lower rope 4 are wound up, the staff can remotely control the installation machine to lower the ropes again via mobile phone, computer, etc.

[0093] In another embodiment of this application, the controller 6 is electrically connected to a current sampling unit and a relay K1. The current sampling unit can be a current sensor, which is installed in the base 11 to detect the current magnitude of the coil output line in the structural block 121. The controller 6 can be a microcontroller controller. The coil of the relay K1 is connected to the relay control terminal of the controller. The normally open contact of the relay K1 is connected in series with the external output terminal of the inductive power supply module 1. When normally powered on, the controller 6 controls the relay K1 to close the normally open contact, so that the inductive power supply module 1 can supply power to the outside normally.

[0094] Controller 6 is configured as follows:

[0095] If the detection value fed back by the current sampling unit meets the preset power-off conditions, such as a detection value of 0 or higher than the maximum safety threshold, then control relay K1 to disconnect the output terminal of the inductive power-off module 1.

[0096] Based on the above settings, it is possible to improve the protection against excessive damage to the fault location system caused by lightning strikes or power transmission short circuits.

[0097] In one embodiment of this application, controller 6 is further configured to:

[0098] Obtain the power of the battery pack from the inductive power supply module 1; for example, obtain the power through the pre-installed battery management module.

[0099] If the detection value fed back by the current sampling unit indicates that the power transmission line is open and the battery pack's charge is less than the preset safety lower limit, then at least the rope reel 8 will be controlled to release the upper rope 3 and the lower rope 4, thus ensuring that even if the power transmission line fails, the staff can still remove the device from the power transmission line.

[0100] It is understandable that after the above-mentioned device is installed, plastic clips, ceramic clips, or other structures can be fixed on the power lines on both sides of the device to prevent the device from sliding left and right at will and affecting its performance.

[0101] This application also discloses a system for locating fault points in power transmission lines.

[0102] Reference Figure 9 The power transmission line fault location system includes a safety disassembly and assembly device for inductive power-collecting equipment, a camera, and a remote management platform as described in any of the above embodiments. The safety disassembly and assembly device for inductive power-collecting equipment is installed on the power transmission line as described above. The camera draws power from the safety disassembly and assembly device for inductive power-collecting equipment, i.e., it is connected to its battery pack. The camera is preferably a night vision camera with wireless networking capabilities, which is installed near the power transmission line by means of a support or other means, with the camera end facing the area to be monitored. The camera is wirelessly connected to the remote management platform so that staff can remotely view the video, quickly understand the situation on the power transmission line, and solve the problem of slow image transmission in special areas, which affects the efficiency of finding power transmission line fault points.

[0103] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
