Description

Technical Field

[0001] This invention relates to the field of power engineering, and more specifically to an installation and disassembly tool for a power distribution network fault indicator. Background Technology

[0002] As a crucial device in distribution network automation management, fault indicators significantly impact power supply reliability. However, existing fault indicators require specialized installation tools, which suffer from several drawbacks. Firstly, the tool's mechanism, relying on a cable spring release to press the indicator onto the distribution network cable, is complex and prone to false triggering. Secondly, during disassembly, the ring arm of the fault indicator is locked to its body, and dust accumulation at the interface in outdoor environments often prevents disengagement, leading to cable damage when the indicator is pulled down forcefully. Therefore, a more convenient installation tool for installing and disassembling fault indicators is needed. Summary of the Invention

[0003] The purpose of this invention is to provide an installation and removal tool for a power distribution network fault indicator, so as to solve the problems of complex triggering mechanisms that are prone to accidental activation and inconvenient disassembly of fault indicators.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tool for installing and removing a power distribution network fault indicator includes a cylindrical body, a snap fastener, a flexible base, a fixing mechanism, and a snap-off mechanism. The cylindrical body has a bottom shell and snap fasteners on its sides. When the snap fasteners are closed, they secure the fault indicator placed inside the cylindrical body, preventing it from detaching. The flexible base is located on the bottom shell inside the cylindrical body, supporting the fault indicator and allowing it to move relative to the cylindrical body. The fixing mechanism is located on the cylindrical body and is used to fix the fault indicator in an open state during installation. When the fault indicator moves downwards relative to the cylindrical body to a designated position, it disengages from the fixing mechanism and returns to a closed state. The snap-off mechanism is located on the top side of the cylindrical body and is used to detach the fault indicator from the cable.

[0006] Optionally, a positioning mechanism may also be included, which is disposed on the elastic base for aligning the fault indicator.

[0007] Optionally, the positioning mechanism includes two opposing magnetic positioning groups, each of which includes multiple magnetic blocks with polarity spaced apart. One magnetic positioning group is located on the elastic base, and the other magnetic positioning group is located at the bottom of the fault indicator.

[0008] Optionally, the bottom shell is provided with a rotating fixing mechanism, which drives the buckle to switch between open and closed states by rotation.

[0009] Optionally, it also includes an operating lever, the first end of which is connected to the rotating fixing mechanism and is used to drive the rotating fixing mechanism to rotate.

[0010] Optionally, the buckling mechanism includes: a locking tooth, a connecting rod, a fixed base, and a state-shifting mechanism. The fixed base is fixedly installed on the top side of the cylindrical body. The fixed base has a connecting hole, and the connecting rod passes through the connecting hole. The first end of the connecting rod is connected to the locking tooth, which is used to open the fault indicator. The second end of the connecting rod is connected to the state-shifting mechanism. When the state-shifting mechanism rotates between a first position and a second position, the connecting rod drives the locking tooth to switch between two states: retracted and extended.

[0011] Optionally, the cylindrical body has a first cable groove and a second cable groove in the axial direction, the first cable groove and the second cable groove being used to accommodate the cable when the fault indicator is installed.

[0012] Optionally, a ring arm groove is also provided on the side wall in the radial direction of the cylindrical body. The ring arm groove is used to provide space for the opening of the ring arm of the fault indicator when the fault indicator is placed inside the cylindrical body.

[0013] Optionally, the fixing mechanism includes a first fixing mechanism, which is a plurality of stops. The plurality of stops are respectively disposed on the first cable groove and the second cable groove. The stops are provided with a pressure spring slot. The pressure spring slot is used to open and fix the pressure spring of the fault indicator. When the fault indicator squeezes the elastic base to retract, the pressure spring disengages from the pressure spring slot.

[0014] Optionally, the fixing mechanism includes a second fixing mechanism, which is a blocking block disposed on the ring arm groove. The blocking block is used to lock the ring arm, so that the ring arm is in an open state. When the fault indicator squeezes the elastic base to retract, the ring arm disengages from the blocking block and returns to a closed state.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention uses an elastic base to control the up-and-down movement of the fault indicator on the cylindrical body. Through the cooperation of the elastic base, the fixing mechanism and the buckling mechanism, the disassembly and assembly triggering mode of the fault indicator is simplified, which can realize convenient and quick disassembly and assembly of the fault indicator and prevent accidental activation.

[0017] 2. The positioning mechanism designed in this invention can easily position the fault indicator in a suitable position in the cylindrical body, thereby facilitating the disassembly and assembly of the fault indicator.

[0018] 3. The present invention incorporates a buckle mechanism that can effectively disengage the ring arm of the fault indicator from the latch, thereby facilitating the disassembly of the fault indicator. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0028] The following detailed description is exemplary and intended to provide further detailed explanation of the invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention.

[0029] like Figure 1-4 As shown, an installation and removal tool for a power distribution network fault indicator includes a cylindrical body 100, a buckle 103, an elastic base 105, a fixing mechanism, and a buckle removal mechanism 310. A bottom shell 101 is provided at the bottom of the cylindrical body 100, and a buckle 103 is provided on the side of the cylindrical body 100. When the buckle 103 is closed, it fixes the fault indicator 200 placed inside the cylindrical body 100, preventing the fault indicator 200 from falling out. An elastic base 105 is provided on the bottom shell 101 inside the cylindrical body 100. The base 105 supports the fault indicator 200, allowing the fault indicator 200 to move relative to the cylindrical body 100. The fixing mechanism is provided on the cylindrical body 100 and is used to fix the fault indicator 200 in an open state during installation. When the fault indicator 200 moves downward relative to the cylindrical body 100 to a designated position, the fault indicator 200 disengages from the fixing mechanism and returns to a closed state. The disassembly mechanism 310 is provided on the top side of the cylindrical body 100 and is used to remove the fault indicator 200 from the cable.

[0030] Specifically, the fault indicator 200 can be a distribution network fault indicator disclosed in CN208588792U.

[0031] Specifically, the cylindrical body 100 has a cavity at its center to accommodate the fault indicator 200. The buckle 103 can be an elastic buckle, specifically an elastic element with a protrusion. When the fault indicator 200 is placed into the cylindrical body 100, the protrusion of the elastic buckle 103 clamps the fault indicator 200. The buckle 103 can also be a buckle that can be controlled to open and close. The bottom of the buckle 103 is connected to a buckle groove on the bottom side of the cylindrical body 100 via a pivot. A torque spring is provided on the pivot. The elastic force of the torque spring keeps the buckle 103 tightly against the cylindrical body 100. A clamping head is also provided on the upper part of the buckle 103. The clamping head is used to hold the fault indicator 200. The top of the clamping head is provided with an inclined surface. When the fault indicator 200 is inserted, the fault indicator 200 presses against the inclined surface, and the latch 103 rotates outward to open. The latch 103 clamps the fault indicator 200 by the elastic force of the torque spring. When the fault indicator 200 reaches the position of the cable, the latch 103 can be triggered to open by rotating the rotating fixing mechanism 102 through the operating lever 104. Specifically, the rotating fixing mechanism 102 can be provided with a protrusion. During the rotation, the protrusion presses the latch 103 outward, causing the latch 103 to open. The elastic base 105 can be a spring-connected base. The up and down movement of the elastic base 105 is achieved by the elasticity of the spring. The elastic base 105 can also be a base made of elastic material, such as rubber.

[0032] As a preferred example, a positioning mechanism 106 is also included, which is disposed on the resilient base 105 for aligning the fault indicator 200.

[0033] In an optional embodiment, the positioning mechanism 106 may be a slot adapted to the shape of the fault indicator 200. When disassembling the fault indicator 200, the present invention can conveniently and quickly align the fault indicator 200, thereby improving efficiency.

[0034] like Figure 5 As shown, in another optional embodiment, the positioning mechanism 106 includes two opposing magnetic positioning groups. Each magnetic positioning group includes multiple magnetic blocks with polarity intervals. One magnetic positioning group is disposed on the elastic base 105, and the other magnetic positioning group is disposed on the bottom of the fault indicator 200. For example, if an N-polarity magnetic block is disposed on the magnetic positioning group, an S-polarity magnetic block is disposed at the corresponding position on the fault indicator 200. Thus, when the fault indicator 200 is placed on the elastic base 105, due to the attraction of opposite magnetic polarities, the fault indicator 200 is automatically positioned in the correct position.

[0035] like Figure 1As shown, in a preferred example, the bottom shell 101 is provided with a rotating fixing mechanism 102, which rotates to switch the latch 103 between open and closed states. For example, the rotating fixing mechanism 102 can be rotatably connected to the bottom shell 101. The rotating fixing mechanism 102 can be provided with a boss. During rotation, the boss touches the latch 103, causing the latch 103 to close. After the boss rotates past the latch 103, the latch 103 can be provided with an elastic device, and the latch 103 opens under the action of the elastic device.

[0036] like Figure 1-5 As shown, in a preferred example, it also includes an operating lever 104. The first end of the operating lever 104 is connected to the rotating fixing mechanism 102 and is used to drive the rotating fixing mechanism 102 to rotate. The second end of the operating lever 104 may be provided with a handle head for easy use. A control switch may be provided on the handle head for controlling the opening and closing of the buckle 103, etc.

[0037] As a preferred example, the release mechanism 310 includes: a locking tooth 3101, a connecting rod 3102, a fixed seat 3105, and a state-toggling mechanism 3104. The fixed seat 3105 is fixedly installed on the top side of the cylindrical body 100. The fixed seat 3105 has a connecting hole 3106. The connecting rod 3102 passes through the connecting hole 3106. The first end of the connecting rod 3102 is connected to the locking tooth 3101. The locking tooth 3101 is used to open the fault indicator 200. The second end of the connecting rod 3102 is connected to the state-toggling mechanism 3104. When the state-toggling mechanism 3104 rotates between the first position and the second position, the locking tooth 3101 is driven to switch between the retracted and extended states through the connecting rod 3102.

[0038] Specifically, the status toggle mechanism 3104 can be a mechanism that drives the connecting rod 3102 to move axially, or it can be a push rod. Before using this device, the position of the status toggle mechanism 3104 can be manually adjusted and fixed. When installing the fault indicator 200, the status toggle mechanism 3104 is moved to the first position and fixed. When disassembling the fault indicator 200, the status toggle mechanism 3104 is moved to the second position and fixed. When the status toggle mechanism 3104 is in the first position, the push rod drives the connecting rod 3102 to retract, and the connecting rod 3102 drives the locking tooth 3101 to be in the retracted state. When the status toggle mechanism 3104 is in the second position, the push rod drives the connecting rod 3102 to extend, and the connecting rod 3102 drives the locking tooth 3101 to be in the extended state, which can be engaged with the fixing buckle 103 of the ring arm 201 of the fault indicator 200 for disassembling and opening the fault indicator 200.

[0039] The buckle release mechanism 310 can also be composed of components such as a locking tooth 3101, a connecting rod 3102, a spring 3103, a fixed seat 3105, and a state-shifting mechanism 3104. The fixed seat 3105 is fixedly installed on the top side of the cylindrical body 100. The fixed seat 3105 has a connecting hole 3106, through which the connecting rod 3102 passes. The locking tooth 3101 is connected to the state-shifting mechanism 3104 through the connecting rod 3102. The locking tooth 3101 can also be connected to the first end of the spring rod. The second end of the spring rod passes through the locking tooth 3101 and is slidably connected to the locking tooth 3101. A spring 3103 is sleeved between the first end of the spring rod and the fixed seat 3105. The state-shifting mechanism 3104 can be a cam, rotatably connected to the side of the fixed seat 3105 away from the center of the cylindrical body 100. The state-shifting mechanism 3104 can rotate between a first position and a second position, thereby driving the locking tooth 3101 to switch between the retracted and extended states. When the status toggle mechanism 3104 is in the first position, the proximal end of the cam contacts the connecting rod 3102. Under the elastic force of the spring, the connecting rod 3102 is pressed tightly against the cam, and the connecting rod 3102 drives the retaining tooth 3101 to be in a retracted state, which does not affect the installation of the fault indicator 200. When the status toggle mechanism 3104 is in the second position, the distal end of the cam presses against the connecting rod 3102, and the connecting rod 3102 drives the retaining tooth 3101 to be in an extended state, which can be engaged with the fixing buckle 103 of the ring arm 201 of the fault indicator 200 for disassembly and opening of the fault indicator 200. The function of the spring 3103 is to keep the connecting rod 3102 pressed tightly against the status toggle mechanism 3104. Specifically, the cam can be connected to a rotary knob, and the user can rotate the knob to adjust the cam state.

[0040] In this invention, a buckle-off mechanism 310 is also provided on the side wall of the cylindrical body 100, at a position corresponding to the ring arm groove 303, such as... Figure 6-7 As shown, the latching mechanism 310 includes: a locking tooth 3101, a connecting rod 3102, a spring 3103, and a state-shifting mechanism 3104. The locking tooth 3101 is connected to the state-shifting mechanism 3104 via the connecting rod 3102. When the state-shifting mechanism 3104 rotates between a first position and a second position, the locking tooth 3101 can switch between two states: retracted and extended. At the same time, the pressure of the spring 3103 keeps the state-shifting mechanism 3104 in the first or second position. Figure 7 As shown, the locking tooth 3101 is in the extended state. At this time, the locking tooth 3101 is engaged with the fixing buckle 103 of the ring arm 201. The inclined surface of the locking tooth 3101 helps the buckle 103 of the ring arm 201 to disengage from the locking position.

[0041] As a preferred example, the cylindrical body 100 has a first cable groove 301 and a second cable groove 302 in the axial direction, which are used to accommodate cables when the fault indicator 200 is installed.

[0042] The width and depth of the first cable tray 301 and the second cable tray 302 can be designed according to different specifications of cables to accommodate different cable diameters. The position and orientation of the first cable tray 301 and the second cable tray 302 can ensure that the installation direction of the fault indicator 200 is consistent with the phase sequence of the cables.

[0043] As a preferred example, a ring arm groove 303 is also provided on the side wall in the radial direction of the cylindrical body 100. The ring arm groove 303 is used to provide space for the opening of the ring arm 201 of the fault indicator 200 when the fault indicator 200 is placed inside the cylindrical body 100.

[0044] The width and depth of the ring arm groove 303 can be designed according to different specifications of fault indicators 200 to accommodate different sizes of ring arms 201. The position and orientation of the ring arm groove 303 can ensure that the ring arm 201 of the fault indicator 200 does not interfere with the side wall of the cylindrical body 100 when it is in the open state.

[0045] As a preferred example, the fixing mechanism includes a first fixing mechanism, which consists of multiple sets of stop arms, including a first stop arm 304, a second stop arm 305, a third stop arm 306, and a fourth stop arm 307. The multiple sets of stop arms are respectively disposed on the first cable groove 301 and the second cable groove 302. The first stop arm 304 and the second stop arm 305 are disposed on the first cable groove 301, and the third stop arm 306 and the fourth stop arm 307 are disposed on the second cable groove 302. The stop arms are provided with a wire pressure spring slot 308, which is used to open and fix the wire pressure spring 202 of the fault indicator 200. When the fault indicator 200 compresses the elastic base 105 to retract, the wire pressure spring 202 disengages from the wire pressure spring slot 308.

[0046] Specifically, there can be four sets of stop arms, with two sets respectively installed on the first cable groove 301 and the second cable groove 302. Each stop arm is equipped with a wire-pressing spring slot 308 for opening and fixing the wire-pressing spring 202 of the fault indicator 200. Each stop arm is equipped with a spring 3103 mechanism, which keeps it in the open state under normal conditions, facilitating the insertion and removal of the fault indicator 200. When the fault indicator 200 is placed inside the cylindrical body 100, the wire-pressing spring 202 of the fault indicator 200 is locked by the wire-pressing spring slot 308 on the stop arm, thus maintaining the open state. When the fault indicator 200 is pressed downward by the cable, the wire-pressing spring 202 of the fault indicator 200 disengages from the wire-pressing spring slot 308, thus returning to the closed state and pressing the fault indicator 200 onto the cable.

[0047] As a preferred example, the fixing mechanism includes a second fixing mechanism, which is a blocking block 309 disposed on the ring arm groove 303. The blocking block 309 is used to lock the ring arm 201, so that the ring arm 201 is in the open state. When the fault indicator 200 squeezes the elastic base 105 to retract, the ring arm 201 disengages from the blocking block 309 and returns to the closed state.

[0048] The ring arm 201 is provided with a protrusion 203, and the blocking block 309 locks the protrusion 203. When the fault indicator 200 squeezes the elastic base 105 to retract, the soil block moves downward relative to the blocking block 309 until it disengages from the blocking block 309. The ring arm 201 returns to the closed state, fixing the fault indicator 200 to the cable.

[0049] The process of using the fault indicator 200 installation and removal tool in this embodiment when installing the fault indicator 200 is as follows:

[0050] First, rotate the buckle 103 to the open position and place the fault indicator 200 inside the cylindrical body 100. Under the magnetic force of the positioning mechanism 106, the fault indicator 200 will be automatically sucked into the appropriate position.

[0051] Then, open the ring arm 201 of the fault indicator 200. Insert the wire springs 202 of the fault indicator 200 into the wire spring slots 308 on the stop arm, so that the wire springs 202 remain in the open state.

[0052] Next, using an insulated long rod, the installation and disassembly tools are brought close to the power distribution cable. Once the power distribution cable is accommodated in the cable tray, the cable presses against the fault indicator 200, and under the action of the elastic base 105, the entire fault indicator 200 moves downward within the cylindrical body 100. As the fault indicator 200 moves downward, it also simultaneously drives the pressure spring 202 and the corresponding protrusion 203 on the annular arm 201 to move downward. When they reach a certain position, the pressure spring 202 disengages from the pressure spring slot 308, and the protrusion 203 disengages from the blocking block 309. This causes the pressure spring 202 of the fault indicator 200 to press against the power distribution cable, while the annular arm 201 closes, and the snap-fit ​​on the annular arm 201 engages with the latch on the fault indicator 200 body to form a fixed position. Figure 4 As shown. This completes the installation of the fault indicator 200.

[0053] The process of using the fault indicator 200 installation and removal tool in this embodiment to remove the fault indicator 200 is as follows:

[0054] First, rotate the buckle 103 to the open position, and at the same time set the buckle release mechanism 310 to the disassembly state.

[0055] Subsequently, the fault indicator 200 located on the power distribution network cable is placed inside the cylindrical body 100, and under the action of the positioning mechanism 106, the fault indicator 200 will be automatically sucked into the appropriate position.

[0056] Next, rotate the insulating rod to close the latch 103, thereby fixing the fault indicator 200 inside the cylindrical body 100. At the same time, the latch teeth 3101 of the release mechanism 310 engage with the latch of the ring arm 201.

[0057] Next, pull down the installation and disassembly tool, and use the locking teeth 3101 to disengage the locking buckle of the ring arm 201 from the locking slot, thereby opening the ring arm 201. At the same time, under the action of the pulling force, the pressure spring 202 of the fault indicator 200 is opened, thereby detaching the fault indicator 200 from the power distribution cable.

[0058] The working principle is as follows: The elastic base 105 and fixing mechanism inside the cylindrical body 100 fix the wire-pressing spring 202 and ring arm 201 of the fault indicator 200 in the open state. Then, the tool, carrying the fault indicator 200, is installed on the power distribution cable. When the cable compresses the fault indicator 200, causing it to move downwards, the wire-pressing spring 202 and ring arm 201 of the fault indicator 200 disengage from the fixing mechanism and return to the closed state, thus pressing the fault indicator 200 onto the cable. To disassemble the fault indicator 200, the locking teeth 3101 of the disassembly mechanism 310 are used to open the ring arm 201 of the fault indicator 200, and then the tool, carrying the fault indicator 200, is removed from the cable.

[0059] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or equivalent to the scope of this invention are included in this invention.

The buckle release mechanism (310) includes: a locking tooth (3101), a connecting rod (3102), a spring (3103), a fixed seat (3105), and a state-shifting mechanism (3104). The fixed seat (3105) is fixedly installed on the top side of the cylindrical body (100). The fixed seat (3105) has a connecting hole. The connecting rod (3102) passes through the connecting hole. The first end of the connecting rod (3102) is connected to the locking tooth (3101), and the second end of the connecting rod (3102) is connected to the state-shifting mechanism (3104). When the state-shifting mechanism (3104) rotates between the first position and the second position, the connecting rod (3102) drives the locking tooth (3101) to switch between the retracted and extended states. The spring (3103) is used to keep the connecting rod (3102) close to the state-shifting mechanism (3104). When the locking tooth (3101) is in the extended state, the locking tooth (3101) engages with the fixing buckle of the ring arm (201), and the inclined surface of the locking tooth (3101) helps the buckle of the ring arm (201) to disengage from the locking opening.
