Description

Technical Field

[0001] The invention relates to the technical field of non-stop power supply operation for distribution network, and in particular to a double-wire quick-locking insulating operating rod for non-stop power supply operation for distribution network and a use method thereof. Background Art

[0002] As one of the important technical means to improve power supply reliability, the distribution network non-stop operation technology has been applied on a large scale in distribution network maintenance. Whether in live disconnection and connection of drainage lines or in fault elimination work, the insulated locking rod plays an important role as one of the common tools to prevent the drainage line from swinging.

[0003] At present, the main structure of the insulating locking rod includes an insulating rod and a rod-end lock. The structural principle is to loosen and lock the wire by rotating the insulating rod to adjust the bolt. When the rod-end lock hooks the wire, the insulating rod is rotated to tighten the screw of the rod-end lock to lock the wire. In the process of locking the wire, the wire to be fixed needs to withstand additional torque, and only a single wire can be locked, which is difficult to meet the safety requirements in some scenarios. There are problems such as low operating efficiency and easy falling of wires.

[0004] To this end, the present application designs a double-wire quick-locking insulating operating rod and a method of use for non-stop power supply operations in the distribution network, so as to fundamentally solve the above-mentioned problems, expand the application scenarios of the insulating locking rod, and help improve the quality and efficiency of non-stop power supply operations. Summary of the invention

[0005] In order to make up for the deficiencies in the prior art, the present invention provides a double-wire quick-locking insulating operating rod for non-stop operation of a distribution network and a use method thereof.

The static lock block has retractable conductive connecting pieces on both sides. The two slidable lock blocks are connected to the push-pull locking device through a push rod and a pull rod respectively. The insulating operating rod plays an insulating and load-bearing role.

[0007] Furthermore, in order to better realize the present invention, the insulating operating rod is a cylindrical rod, a part of the bottom of one end of which is cut into an axle-flattened shape, an intermediate locking block is fixedly connected to the bottom center of the axle-flattened part, a long groove is opened in the upper center of the axle-flattened part as a movable groove, an outer locking block is slidably connected in the movable groove, an inner locking block is slidably connected at the left end of the axle-flattened part, and the intermediate locking block is located between the outer locking block and the inner locking block.

[0008] Furthermore, in order to better realize the present invention, the end of the movable groove is fixedly connected with a rod end plug, and retractable conductive connecting pieces are provided on both sides of the middle locking block, which can realize the priority conduction of the main line and the lead line to avoid the risk of human body being connected to the circuit, and the retractable conductive connecting pieces on both sides are connected to the internal spring of the middle locking block; the conductive connecting piece is in an extended state in the free state, and the extended length is greater than the thickness of the insulation layer of the 10 kV distribution network overhead insulated wire. After the locking wire is subjected to force, the conductive connecting piece shrinks and closely contacts the main line and the lead line to ensure that the main line and the lead line are reliably conductive, and the stripping length can be reduced, reducing the workload of line insulation management; the top of the outer locking block and the inner locking block are provided with a raised locking block limit card which is clamped in the flat part of the insulating operating rod.

[0009] Furthermore, in order to better implement the present invention, the outer locking block is fixedly connected to a pull rod, which is slidably connected to a push-pull rod positioning hole set on the insulating operating rod, and the inner locking block is fixedly connected to a push rod, which is slidably connected to a push-pull rod positioning hole set on the insulating operating rod.

[0010] Furthermore, in order to better realize the present invention, one end of the push rod is rotatably connected to the push rod handle by rotating the connecting device, the push rod handle is provided with a push rod locking tooth, the push rod handle passes through the push rod locking device connected to the insulating operating rod, and the inner bottom surface of the push rod locking device is also provided with a locking tooth; one end of the pull rod is rotatably connected to the pull rod handle by rotating the connecting device, the pull rod handle is provided with a pull rod locking tooth, the pull rod handle passes through the pull rod locking device connected to the insulating operating rod, and the inner bottom surface of the pull rod locking device is also provided with a locking tooth. When the handle is rotated to make the locking teeth coincide, the wire can be instantly locked and locked to prevent loosening; when the handle is rotated to make the locking teeth staggered, the wire can be loosened.

[0011] Based on the above equipment, its usage is as follows: S1: Distribution network uninterrupted operation personnel enter the appropriate work area under the premise of setting up insulation shielding and ensuring safe working distance, first measure the lead length, and complete the main line and lead stripping operation; S2, the operator pushes the push rod handle outward to lock the lead wire through the inner locking block and the middle locking block; S3, the operator moves the insulating operating rod, places the main line between the outer locking block and the middle locking block, and then pulls the pull rod handle inward. At this time, the operating rod locks the main line and the lead wire at the same time, and achieves reliable conduction through the retractable conductive link. At this time, the operator can install the wire clamp to complete the lead wire connection operation; S4, after confirming that the wire clamp is firmly installed, the operator takes back the insulating operating rod and completes the operation of connecting the drainage line; the operator can complete the operation of connecting other drainage lines according to the same steps.

[0012] The beneficial effects of the present invention are: The present invention has an ingenious structure. It can quickly lock the wires through simple push and pull operations. It is equipped with a double-wire slot. Through a retractable conductive link, it can achieve priority and reliable conduction of the main line and the lead wire, avoiding the risk of human input into the circuit, and significantly improving the work efficiency. During the operation, the tool is convenient and easy to use. During the process of locking the wires, the wires do not need to be stressed. Single wires and double wires can be quickly locked according to the usage scenario, which fundamentally solves the problem of locking unfixed wires, greatly improves work efficiency and operation safety, and further ensures the safety of operators.
