Description

Technical Field

[0001] The present invention relates to the technical field of power equipment maintenance tools, and in particular to a high-voltage intelligent drop-type fusion tube gripper insulating operating rod and a replacement method. Background Art

[0002] In the current power system, high-voltage intelligent drop-out fuses, as an important overload and short-circuit protection device, are gradually replacing traditional high-voltage drop-out fuses and are widely used in 10kV distribution lines and the primary side of substations, significantly improving the safety of the system and the reliability of power supply. However, in actual operation, the traditional drop-out fuse tube replacement method has many limitations and problems, which are mainly manifested in the following aspects:

[0003] Complex operation and low efficiency: The traditional method of replacing the fuse tube usually requires the operator to hold an insulating rod for high-altitude operation. When installing or replacing the fuse tube, the fuse tube needs to be accurately aligned with the fixed position and inserted, which not only requires the operator to have high technical proficiency, but also needs to complete the task in a small operating space, which is time-consuming and difficult, and easily leads to operational delays.

[0004] High safety risk: Traditional operation methods require operators to approach high-voltage equipment, which is prone to safety accidents. Especially in severe weather or complex environments outdoors, the instability factors in the operation process increase significantly, posing a greater safety hazard. Melt tube slippage and operational errors often occur, which may cause equipment damage or personal injury.

[0005] Equipment damage and increased maintenance costs: In traditional operations, the melting tube is easily damaged by slipping to the ground due to mistakes during placement, which not only requires replacement, but also causes equipment wear and unnecessary economic losses. In addition, the replacement process is time-consuming, which may lead to longer power outages, affect the continuity of power supply, and increase the maintenance costs of the power company.

[0006] At present, there are some related technologies and devices that attempt to solve the above problems, such as:

[0007] Automatic replacement drop-out fuse control system: This system realizes the automation of remote opening and closing and fuse replacement, and reduces manual intervention through automatic logic control. However, the system is expensive, has limited applicability, and requires relatively complex system integration, making it difficult to be widely used in various distribution lines.

[0008] Temporary connection device: Some temporary devices can replace fuses without power failure, which is suitable for the emergency maintenance needs of important users. However, the structure of such devices is relatively simple, the stability is poor, and safety problems are prone to occur in high-altitude operations or harsh environments.

[0009] Quick replacement device: For example, the drop fuse quick replacement device developed by Guizhou Power Grid can achieve quick replacement after the fuse explodes or fails, reducing power outage time. However, this device is mostly used in emergency situations after high-voltage fuse explosions and is not an ideal solution for daily maintenance.

[0010] Although the existing technology has developed, it is still difficult to effectively solve the safety, efficiency and cost problems in the operation of high-voltage melting tubes. The high-voltage intelligent drop-type melting tube gripper insulated operating rod proposed in the present invention realizes safer and faster melting tube grasping and replacement operations through intelligent gripper design and motor control system, which is expected to fill the gap in the existing technology and provide an efficient and stable solution.

[0041] The following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0042] For the replacement of the drop-out fuse tube of the high-voltage intelligent drop-out fuse, this embodiment provides a high-voltage intelligent drop-out fuse tube gripper insulating operating rod; Figure 1 As shown, the high-voltage intelligent drop-type molten tube gripper insulating operating rod comprises an insulating operating rod 1 and a high-voltage intelligent drop-type molten tube gripper 3 installed on one end of the insulating operating rod 1 through a connecting sleeve 2.

[0043] like Figure 2 and Figure 3 As shown, in this embodiment, the high-voltage intelligent drop-type fuse tube gripper 3 includes a coaxially arranged battery box 4 and a motor mounting sleeve 5, as well as a fixed gripping plate 6 and a movable gripping plate 7; wherein, the fixed gripping plate 6 is fixedly mounted on the motor mounting sleeve 5 through a fixing frame 11, and the movable gripping plate 7 is located above the fixed gripping plate 6, and the movable gripping plate 7 is connected to the output end of the motor through a transmission guide assembly, and the movable gripping plate 7 can be moved vertically through the motor to cooperate with the fixed gripping plate 6 to clamp the drop-type fuse tube.

[0044] like Figure 2 and Figure 3 As shown, in this embodiment, the battery box 4 is a rectangular box structure, and the battery box 4 is equipped with a battery and a control circuit board 8, and the circuit board is connected to the battery by wire; Figure 1 As shown, the control circuit board 8 is equipped with a remote controller 9. Figure 2 and Figure 3 As shown, the motor mounting sleeve 5 is a cylindrical tube structure, and a lifting motor 10 is installed inside the motor mounting sleeve 5. The lifting motor 10 is wiredly connected to the circuit board through an external wiring tube 20. In addition, considering the heat dissipation problem of the lifting motor 10, Figure 2 As shown, in this embodiment, a plurality of waist-shaped heat dissipation holes are arranged on the motor mounting sleeve 5.

[0045] like Figure 2 and Figure 3 As shown, considering the installation of the fixing frame 11, in this embodiment, a mounting seat for cooperating with the fixing frame 11 is provided on the motor mounting sleeve 5; the fixing frame 11 is a group of T-shaped plate structures, a group of T-shaped plates are symmetrically installed on the mounting seat of the motor mounting sleeve 5, and a gap is reserved between the group of T-shaped plate structures to cooperate with the installation of the transmission guide assembly; the fixed grab plate 6 is fixedly installed on the group of T-shaped plate structures.

[0046] like Figure 2 and Figure 3As shown, the transmission guide assembly in this embodiment has two functions: first, it transmits the power of the output end of the motor so that the movable gripping plate 7 can move vertically through the motor to cooperate with the fixed gripping plate 6 to clamp the drop-type melting tube; second, it guides the vertical movement of the movable gripping plate 7. The first function is realized by the transmission assembly of the transmission guide assembly; Figure 2 and Figure 3 As shown, the transmission assembly is installed in the gap between a group of T-shaped plate structures, and the transmission assembly includes a transmission screw 12 and a transmission nut 13; one end of the transmission screw 12 is fixedly connected to the output end of the motor, and the other end is rotatably installed on the fixed clamping plate 6 through a bearing, and the transmission nut 13 is threadedly connected to the transmission screw 12. The second function is achieved by the guide assembly of the transmission guide assembly; as shown in FIG. Figure 2 and Figure 3 As shown, the guide assembly includes a trapezoidal connector 14, one end of which is fixedly connected to the driving nut 13, and the trapezoidal connector 14 is fitted with one side of a set of T-shaped plate structures, and the other end of the trapezoidal connector 14 is fixedly mounted with the movable gripping plate 7. Further, in order to assist the vertical movement of the movable gripping plate 7, a guide block is further provided on one side of the fixed gripping plate 6 in this embodiment, and at the same time, as shown in FIG. Figure 2 and Figure 3 As shown, a slide groove 15 cooperating with the guide block is also provided on the trapezoidal connecting member 14 .

[0047] like Figure 2 and Figure 3 As shown, in this embodiment, since the fixed grasping clamping plate 6 and the movable grasping clamping plate 7 are used to clamp the drop-type melting tube, an arc groove for clamping the drop-type melting tube is provided on the fixed grasping clamping plate 6 and the movable grasping clamping plate 7. In addition, in order to avoid excessive holding force to damage the drop-type melting tube, as shown in FIG. Figure 2 and Figure 3 As shown, in this embodiment, gripper rubber pads 16 are installed in the arc grooves of the fixed gripping plate 6 and the movable gripping plate 7.

[0048] As the preferred technical solution of this embodiment, considering that when replacing the drop-type melting tube in some narrow spaces, the high-voltage intelligent drop-type melting tube gripper 3 needs to be adjusted to a certain angle to meet the installation and removal position of the drop-type melting tube. Figure 2 and Figure 3As shown, the bottom of the motor mounting sleeve 5 in this embodiment forms a connection seat, and swing shafts 17 are symmetrically arranged on both sides of the outer body of the battery box 4, and the connection seat is connected to the swing shaft 17 through a shaft body connector; in addition, a horizontal swing motor 18 connected to the control circuit board 8 is also installed on the upper part of the battery box 4, and the output shaft of the horizontal swing motor 18 is connected to any swing shaft 17. In this way, the swing shaft 17 is driven to rotate by the horizontal swing motor 18, so that the motor mounting sleeve 5, the fixing frame 11, the fixed gripping plate 6 and the movable gripping plate 7 are swung to a certain angle relative to the battery box 4, so as to meet the installation and removal position of the drop-type fuse.

[0049] As the preferred technical solution of this embodiment, in order to ensure the stability of the high-voltage intelligent drop-type melting pipe gripper 3 during long-term operation, Figure 2 As shown, a fixing block 19 is also provided at the swing shaft 17 outside the battery box 4. The fixing block 19 can be detachably installed, and it can position the swing shaft 17, reduce the burden on the motor, prevent vibration and accidental loosening, and improve the stability and durability of the overall structure.

[0050] The high-voltage intelligent drop-type fuse gripper 3 of the high-voltage intelligent drop-type fuse gripper insulating operating rod is controlled by a horizontal swing motor 18 and a lifting motor 10. The angle of the high-voltage intelligent drop-type fuse gripper 3 is adjusted by the horizontal swing motor 18, and the vertical movement of the movable gripping plate 7 is controlled by the lifting motor 10, and the fixed gripping plate 6 is cooperated to complete the clamping action of the drop-type fuse, so as to achieve accurate clamping and release of the drop-type fuse, and ensure that the drop-type fuse can be effectively aligned and clamped, so as to quickly and stably grasp or release the fuse when replacing the drop-type fuse. The operating rod is made of high-strength insulating material to ensure the safety protection of operators in high-voltage working environments; the upper end of the operating rod is fixed by connecting sleeves, fasteners and other fixing methods to achieve stable mechanical connection, ensuring that the high-voltage intelligent drop-type fuse gripper 3 does not loosen during operation; the insulation of the operating rod effectively reduces the risk of electric shock in high-voltage operations. The battery box 4 integrates batteries and a control circuit board 8. The control circuit board 8 receives operation instructions through the remote controller 9 to control the forward and reverse rotation and start and stop of the horizontal swing motor 18 and the lifting motor 10. The battery assembly provides power support to ensure the independent operability and convenience of the equipment. The operator can use the remote controller 9 to accurately control the swing angle and clamping degree of the high-voltage intelligent drop-type melting pipe gripper 3 to avoid direct contact with the equipment under high-voltage environment; the remote controller 9 can realize multiple functions such as adjusting the gripper position and releasing the melting pipe, realizing remote control in a high-voltage environment.

[0051] Based on the above-mentioned high-voltage intelligent drop-type fuse gripper insulating operating rod, this embodiment also proposes a manual fuse replacement method, which includes the following steps:

[0052] Step 1, preparation stage: Disconnect the power supply, ensure that the power supply of the equipment to be replaced is turned off, and the lock mark is marked; wear insulating gloves and safety goggles to ensure personal safety during the operation.

[0053] Step 2, check the equipment: Before further operation, check the status of the old melting tube to confirm whether it needs to be replaced; ensure that there are no other people in the work area and set up safety warning signs.

[0054] Step 3, set the gripper: connect the insulating operating rod 1 of the high-voltage intelligent drop-type fuse pipe gripper insulating operating rod to the high-voltage intelligent drop-type fuse pipe gripper 3 to ensure a firm connection; test the remote control 9 to confirm that all button functions are normal, including the swing angle and clamping adjustment of the gripper.

[0055] Step 4, operate the gripper: use the remote control 9 to control the horizontal swing motor 18, adjust the high-voltage intelligent drop-type fuse pipe gripper 3 to a suitable angle, align the high-voltage intelligent drop-type fuse pipe through the insulating operating rod 1, and make the high-voltage intelligent drop-type fuse pipe be located between the fixed gripping plate 6 and the movable gripping plate 7; start the lifting motor 10, and control the movable gripping plate 7 through the remote control 9 to cooperate with the fixed gripping plate 6 to clamp the drop-type fuse pipe.

[0056] Specifically, when the horizontal swing motor 18 is started, the output shaft of the horizontal swing motor 18 drives any swing shaft 17 to rotate, and the swing shaft 17 drives the motor mounting sleeve 5, the fixing frame 11, the fixed gripping plate 6 and the movable gripping plate 7 to swing to a certain angle relative to the battery box 4, thereby meeting the installation and disassembly position of the drop-type fuse. When the lifting motor 10 is started, the motor output end drives the transmission screw 12 to rotate forward or reversely. After the transmission screw 12 rotates forward or reversely, since the transmission nut 13 is threadedly connected to the transmission screw 12, and the trapezoidal connector 14 is in contact with one side of a group of T-shaped plate structures, the rotation of the transmission nut 13 is rotationally limited, so the transmission nut 13 is lifted relative to the transmission screw 12. When the transmission nut 13 is lifted, the movable gripping plate 7 is lifted relative to the fixed gripping plate 6 through the trapezoidal connector 14, thereby achieving the clamping or loosening action, and completing the clamping or loosening of the drop-type fuse. When the movable grabbing plate 7 is lifted and lowered relative to the fixed grabbing plate 6, the trapezoidal connecting member 14 slides relative to the guide block on the fixed grabbing plate 6 through the sliding groove 15 to form an auxiliary guiding effect.

[0057] Step 5, replace the fuse tube: after ensuring that the gripper is stable, gently rotate the old high-voltage intelligent drop-type fuse tube through the insulating operating rod 1 to disengage it from the drop-type device; repeat step 4 to make the dynamic gripping plate cooperate with the fixed gripping plate 6 to clamp the new high-voltage intelligent drop-type fuse tube.

[0058] Step 6, complete the replacement: insert the new high-voltage intelligent drop-out fuse tube into the drop-out device through the insulating operating rod 1. After restoring the connection of the drop-out device, release the lock and warning signs of the equipment, restore the power supply and perform the test to complete the manual fuse tube replacement.

[0059] In summary, the high-voltage intelligent drop-type fuse tube gripper insulated operating rod and replacement method solve the problems of complex fuse tube replacement process, low efficiency, insufficient safety and high risk of equipment damage in high-voltage power distribution systems; through the combination of intelligent gripper design and motor control system, the fuse tube grabbing and replacement operations can be completed quickly and stably, significantly improving operational efficiency, reducing the risk of operators directly contacting high-voltage equipment, and effectively ensuring operational safety; at the same time, it can avoid accidental slipping of the fuse tube during the replacement process, reduce equipment damage, and thus improve the continuity and reliability of the power supply system. The high-voltage intelligent drop-type fuse tube gripper insulated operating rod not only provides an efficient and safe high-voltage fuse tube replacement solution, but also meets the power system's needs for rapid maintenance and continuous power supply.

[0060] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
