Description

Technical Field

[0001] The present invention relates to the field of electric power engineering, and in particular to a device for adjusting the position of a feeder automation terminal. Background Art

[0002] The feeder automation terminal (FTU) is a core device in the distribution network automation system, primarily used for real-time monitoring and control of equipment on the distribution line (such as pole-mounted switches and ring main units). It uses high-precision sensors to collect operating parameters such as voltage, current, and power, and, in conjunction with a communication module, uploads this data to the master station system. It also receives and executes remote control commands (such as opening and closing operations). The FTU has fault detection and location capabilities, quickly identifying abnormal conditions such as short circuits and grounding. By coordinating with the master station or making autonomous decisions through edge computing, it achieves precise isolation of faulty sections and restoration of power to non-faulty areas, significantly improving the reliability and self-healing capabilities of the distribution network.

[0003] In the actual construction of distribution network automation systems, feeder automation terminals (FTUs) are usually installed in the upper middle part of poles to ensure signal coverage and equipment safety. During the installation process, a lifting device is required to complete the equipment installation. This high-altitude deployment method requires construction personnel to climb to a work point more than 2 meters above the ground for manual operation, including equipment commissioning, parameter setting, and daily maintenance. This not only significantly increases labor intensity and operation time, but also poses the risk of falling from height during the climbing process. Especially in severe weather conditions such as rain, snow, and strong winds, the safety risks of pole-mounted operations are further exacerbated. At the same time, the reduced operating accuracy caused by the complex environment directly affects the efficiency of equipment commissioning. Summary of the Invention

[0014] In a preferred embodiment of the device for adjusting the position of a feeder automation terminal of the present invention: the partition is inserted into the rope loop wound around the outer wall of the second roller, thereby separating adjacent rope loops of the connecting rope.

[0015] In a preferred embodiment of the device for adjusting the position of a feeder automation terminal of the present invention: the second free end is in contact with the rough rod portion;

[0016] The second free end is inclined toward the side close to the rough rod portion, and the upward winding of the second free end can drive the locking column to move synchronously, and the rough rod portion can press the connecting rope tightly against the outer wall of the second roller.

[0017] In a preferred embodiment of the device for adjusting the position of a feeder automation terminal of the present invention: the second free end is inclined toward a side away from the rough rod portion, and the second free end is separated from the rough rod portion;

[0018] The locking column falls back to the bottom position of the arc groove under the action of gravity.

[0019] In a preferred embodiment of the device for adjusting the position of a feeder automation terminal according to the present invention:

[0020] It comprises a supporting unit, a hoop, and a fixing rod connected to the hoop;

[0021] The clamp fixes the fixing rod to one side of the electric pole;

[0022] A slider is fixedly installed on the outer side of the connecting rope, and the end of the slider is connected to the terminal body.

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0039] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0040] Reference Figure 1 and Figure 2 The present embodiment provides a device for adjusting the position of a feeder automation terminal, comprising a traction unit 1, wherein the traction unit 1 comprises a fixed pulley 11, a fixing frame 12, a first roller 13, a second roller 14, a connecting rope 15 and a locking column 16; wherein the fixed pulley 11 is installed at the top position of a support sleeve, and the fixing frame 12 is located at the bottom position of the support sleeve, and the fixed pulley 11 and the fixing frame 12 are arranged opposite to each other; the interior of the fixing frame 12 is divided into two spaces, and the first roller 13 and the second roller 14 are respectively located in the two spaces and rotate relatively independently. The two wheels 13 and 14 are connected to each other by means of the locking post 16. The two wheels 13 and 14 are connected to each other by means of the locking post 16. The two wheels 13 and 14 are connected to each other by means of the locking post 16. The two wheels 13 and 14 are connected to each other by means of the locking post 16.

[0041] In this embodiment, the connecting rope 15 is passed through the fixed pulley 11 at the top, and then the two groups of free ends of the connecting rope 15 are pulled to drive the height position of the connecting rope 15 to change, thereby changing the position of the slider connected to the connecting rope 15; in order to further ensure that the connecting rope 15 can be fixed, the two free ends of the connecting rope 15 are respectively wrapped around the outside of the first roller 13 and the second roller 14, and the stretched position of the connecting rope 15 is fixed by the friction between the locking column 16 and the connecting rope 15.

[0042] It should be noted that pulling the free end on one side of the connecting rope 15 can drive the connecting rope 15 to move along the slider connected to the outside. Pulling one group of free ends can drive the slider to move upward, and conversely pulling the other group of free ends can drive the slider to move downward. By pulling different positions on both sides of the connecting rope, the slider can be driven to move.

[0043] refer to Figure 1 and Figure 2 As an optional embodiment, it includes a fixed pulley 11 and a fixed frame 12 distributed up and down along the vertical axis, a first roller 13 and a second roller 14 are respectively located inside the fixed frame 12 and rotated apart; a connecting rope 15 passes through the fixed pulley 11, a first free end 151 of the connecting rope 15 is wrapped around the outside of the first roller 13, and a second free end 152 is wrapped around the outside of the second roller 14; the first free end 151 and the second free end 152 both pass through the fixed frame 12 and extend outward.

[0044] In this embodiment, the fixed pulley 11 and the fixed frame 12 are arranged opposite to each other along the vertical axis, and the positions of the fixed pulley 11 and the fixed frame 12 correspond to each other; after the connecting rope 15 passes through the pulley inside the fixed pulley 11, its first free end 151 is wrapped around the outside of the first roller 13, and the first free end 151 is wrapped around the outside of the first roller 13 for at least one circle; and the second free end 152 is wrapped around the outside of the second roller 14; the first free end 151 can be used to control the height position of the slider arranged on the outside of the connecting rope 15 to move downward during the movement; by pulling the second free end 152 to move, the slider connected to the outside of the connecting rope 15 can be controlled to move upward.

[0045] refer to Figure 3 In one embodiment provided in the present application, the fixing frame 12 includes an arcuate groove 121 opened on its side wall and a through hole 122 passing through its bottom; the first free end 151 and the second free end 152 pass through the through hole 122 and extend to the outside thereof.

[0046] In this embodiment, a through hole 122 is provided at the bottom of the fixing frame 12, and the through hole 122 passes through the bottom of the fixing frame 12; the second free end 152 and the first free end 151 can pass through the through hole 122 and extend to the outside thereof during the process of naturally hanging down; thereby ensuring that the second free end 152 and the first free end 151 can naturally hang down along the tangent position of the outer wall of the winding roller.

[0047] It should be noted that the length direction of the through hole 122 can satisfy the second free end 152 and the first free end 151 to be deflected at a certain angle therein, so that the second free end 152 or the first free end 151 can be tilted to one side.

[0048] refer to Figure 5 In one embodiment provided in the present application, the locking column 16 includes a partition 161, and a smooth rod portion 162 and a rough rod portion 163 separated by the partition 161; the locking column 16 is adapted to the arc groove 121, and the locking column 16 moves along a specific trajectory of the inner wall of the arc groove 121.

[0049] In this embodiment, the locking column 16 passes through the side wall of the fixing frame 12 and moves along the track opened inside the arc-shaped groove 121, and the partition 161 is arranged at the middle position of the locking column 16, and the partition 161 divides the locking column 16 into a smooth rod portion 162 and a rough rod portion 163; the outer surface of the rough rod portion 163 is provided with rough texture, and its friction force is relatively large. When the rough rod portion 163 contacts the connecting rope 15, the outer surfaces of both are not smooth. When the connecting rope 15 needs to move, the position of the connecting rope 15 can be limited by friction.

[0050] It should be noted that the outer surface of the smooth rod 162 is smooth, which can limit the connecting rope wrapped around the outside of the roller, so that the smooth rod 162 presses the connecting rope against the outer surface of the roller, thereby effectively preventing the connecting rope from loosening from the roller surface.

[0051] Furthermore, the roller is arranged inside the fixing frame 12, and the thickness of the roller is adapted to the rotatable space inside the fixing frame 12; this ensures that the roller rotates inside the fixing frame 12, and at the same time effectively prevents the connecting rope wrapped around the outside of the roller from detaching from the roller surface.

[0052] refer to Figure 5 As an optional embodiment, a partition 161 is inserted into the rope loop wrapped around the outer wall of the second roller 14, thereby separating the rope loops of adjacent connecting ropes 15.

[0053] In this embodiment, the partition 161 is inserted into the rope loop outside the roller to separate the second free end 152 that hangs down on one side from the other rope loops of the roller, thereby effectively avoiding the influence of the outer wall of the rough rod 163 on other rope loops, which in turn causes the connecting rope 15 to be difficult to move.

[0054] refer to Figures 1 to 4 In some embodiments, the second free end 152 is in contact with the rough rod 163; the second free end 152 is inclined toward the side close to the rough rod 163, and the upward winding of the second free end 152 can drive the locking column 16 to move synchronously, and the rough rod 163 can press the connecting rope 15 against the outer wall of the second roller 14.

[0055] In this embodiment, taking the upward movement of the slider provided on the outer wall of the connecting rope 15 as an example, under normal conditions, the slider provided on the outer side of the connecting rope 15 is moved by pulling the second free end 152. When the slider moves to a suitable position, the downward pulling force is stopped; and the second free end 152 is swung toward the side close to the rough rod 163, so that the second free end 152 is close to the outer wall of the rough rod 163; at this time, the slider has a tendency to move downward under the action of gravity, thereby pulling the second free end 152 upward; The friction between the second free end 152 and the rough rod 163 is relatively large. When the second free end 152 moves upward, the rough rod 163 also moves upward synchronously with the second free end 152. During the movement, the rough rod 163 moves along a specific trajectory on the inner wall of the arc groove 121. After the rough rod 163 moves to the top position of the arc groove 121, its position is fixed. Since the rough rod 163 is fixed, the position of the connecting rope 15 can also be fixed, so that the connecting rope 15 is pressed between the roller and the rough rod 163.

[0056] Furthermore, the clamped and fixed position of the rough rod 163 and the connecting rope 15 is along the vertical direction of the roller tangent. After the staff swings it to one side, the second free end 152 can be in a natural hanging state. At this time, the second free end 152 is fixed by the rough rod 163, thereby achieving the fixation of the position of the connecting rope 15.

[0057] In one embodiment provided in the present application, the second free end 152 is inclined toward a side away from the rough rod portion 163 , and the second free end 152 is separated from the rough rod portion 163 ; the locking column 16 falls back to the bottom position of the arc groove 121 under the action of gravity.

[0058] In this embodiment, when it is necessary to readjust the position of the slider arranged on the outside of the connecting rope 15, it is first necessary to swing the second free end 152 so that the second free end 152 is tilted toward the side away from the rough rod 163, and then the contact area between the rough rod 163 and the second free end 152 is reduced. Then, the second free end 152 is pulled downward along the tilting direction, which can drive the locking column 16 to fall back to the bottom position of the movement trajectory of the arc groove 121, thereby releasing the limit on the connecting rope 15; and then the first free end 151 on the other side is pulled to drive the slider arranged on the outside of the connecting rope 15 to move downward. When it moves to the appropriate position, the position of the descending slider is fixed in the same way as the slider rises; thereby, the position of the slider can be adjusted, and the slider can be locked after moving to the appropriate position.

[0059] In summary, the position of the slider can be adjusted by the present device, and the entire device has a simple structure, is easy to operate, and has a low movement cost, so it can be put into mass production.

[0060] Reference Figure 1 and Figure 5 This embodiment provides a method for determining the life of a connecting rope, including a support unit 2, including a clamp 21, and a fixing rod 22 connected to the clamp 21; the clamp 21 fixes the fixing rod 22 to one side of the electric pole; a slider 4 is fixedly installed on the outer side of the connecting rope 15, and the end of the slider 4 is connected to the terminal body 3.

[0061] In this embodiment, the clamp 21 is a metal connecting piece with one end hinged to each other, and the other end is a free end that can be fixed to the clamp 21 by bolts; the clamp 21 is put on the outside of the utility pole, and then the free ends of the clamp 21 are fitted together, and then the clamp 21 is fixed to the outside of the utility pole by bolts; the side wall of the clamp 21 extends outward and is connected to a fixed ring, and a fixed rod 22 is provided inside the ring, and the ring and the fixed rod 22 are fixedly connected, and a slider 4 is provided on the outside of the connecting rope 15, and the slider 4 can move synchronously along the connecting rope 15; the slider 4 is fixed to the terminal body 3 by bolt connection, and the movement of the slider 4 can drive the terminal body 3 to move.

[0062] It should be noted that the slider 4 is located inside the fixed rod 22 and can move up and down, and the slider 4 is adapted to the inner wall diameter of the fixed rod 22; an arc-shaped notch is provided on the side wall of the slider 4, which ensures that the connecting rope 15 hanging from the top of the fixed pulley 11 has enough space to move inside the fixed rod 22, effectively preventing the connecting rope 15 from being stuck by the slider 4, causing the device to fail to operate normally.

[0063] As an optional embodiment, the fixed pulley 11 is arranged on the top inner wall of the fixed rod 22, and the fixing frame 12 is arranged on the bottom inner wall of the fixed rod 22; the free end of the connecting rope 15 passes through the fixed rod 22 and extends to the outside thereof.

[0064] In this embodiment, the fixed pulley 11 is arranged inside the fixed rod 22, and the fixed pulley 11 and the fixed rod 22 are interference fit, and the positions of the fixed pulley 11 and the fixed rod 22 are relatively fixed; the fixed frame 12 is arranged at the inner bottom of the fixed rod 22, and the fixed frame 12 and the fixed rod 22 are interference fit; the fixed rod 22 can provide reasonable support for the fixed pulley 11 and the fixed frame 12.

[0065] In some embodiments, a sliding groove 221 is formed on the side wall of the fixing rod 22 , and the slider 4 passes through the sliding groove 221 and extends to the outside thereof; the first free end 151 and the second free end 152 respectively control the lifting and lowering of the slider 4 .

[0066] In this embodiment, a sliding groove 221 is provided on the side wall of the fixing rod 22, and the connecting portion of the slider 4 passes through the sliding groove 221 and extends to its outside. The position of the slider 4 can be limited by the sliding groove 221, thereby ensuring that the slider 4 can move along the axial direction; one side of the slider 4 is also connected to the terminal body 3. When the slider 4 moves along the connecting rope 15, the terminal body 3 also moves synchronously with the connecting rope 15.

[0067] Furthermore, when it is necessary to lower the position of the terminal body 3, pulling the first free end 151 can drive the slider 4 to move, and then the position of the terminal body 3 can be fixed through the cooperation between the locking column 16 and the first free end 151, thereby ensuring that the terminal body 3 can be fixed after being lowered to the appropriate position, which can better facilitate the operation of the staff; moving the terminal body 3 to a lower position can reduce the labor burden of the staff and can quickly complete the operation of the terminal body 3.

[0068] This embodiment provides a method for judging the life of a connecting rope. During the operation of the traction unit, the connecting rope is manually operated to observe the resistance when the locking column moves along the arc groove of the side wall of the fixing frame. When the connecting rope contacts the rough rod, it is judged by hand whether the friction force increases significantly, such as a significant increase in resistance or unsmooth movement, so as to evaluate the wear condition of the connecting rope.

[0069] A mechanical counter, such as a gear-linked counting device, is provided on the outside of the fixed frame. Each time the connecting rope completes a lifting operation, the counter is driven to accumulate once by the rotation of the first roller or the second roller. The operator regularly checks the accumulated number of operations displayed on the counter and manually records it in the maintenance log.

[0070] Based on preset wear threshold standards, such as an upper limit of 5,000 operations, or through regular sampling inspections to check whether broken wires or cracks appear on the surface of the connecting rope, combined with the cumulative number of operations and manual resistance assessment results, it is determined whether the connecting rope has reached the end of its life; if the number of operations exceeds the upper limit or obvious signs of wear are observed, it is determined that replacement is required.

[0071] When the service life is determined to be over, a mechanical warning sign, such as a reversible red sign, is set in a conspicuous position on the fixed pole, and the replacement requirement is marked in the maintenance log; during regular inspections, the operator manually lowers the terminal body to a lower position and replaces the connecting rope according to the prompts on the sign or log.

[0072] During distribution network maintenance, a feeder automation terminal required monthly position adjustment and parameter calibration. Operators noticed a significant increase in resistance when raising or lowering the connecting rope, and the mechanical counter indicated a cumulative operation count of 4,800, approaching the preset upper limit of 5,000. A visual inspection revealed multiple broken wires on the connecting rope. The operator then flipped the red label on the mounting rod and recorded the need for replacement in the maintenance log. During subsequent maintenance, the operator manually lowered the terminal to replace the connecting rope, avoiding the potential risk of breakage.

[0073] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
