Description

Technical Field

[0001] This invention relates to the field of power maintenance technology, and in particular to an insulated lead-out wire reel. Background Technology

[0002] With the increasing reliance of the national economy on electricity supply, the requirements for the safe operation and reliability of the power system are also becoming more stringent. Live-line work is becoming a growing trend. In live-line work, insulated lead-in wires are often used to construct small bypass systems, isolating the equipment to be maintained and enabling live-line maintenance. During the replacement of sectional disconnectors under load, insulated lead-in wires are typically coiled and placed on crossarms with proper insulation and shielding measures, and then installed on both sides of the line.

[0003] However, with this method of placing insulated guide wires, the crossarms need to be insulated and shielded in advance. Insulation shielding not only has the problems of large workload and low efficiency, but also has the risk of incomplete shielding. In addition, the coiled insulated guide wires in this method have no fixing measures, and the coiled insulated guide wires may fall and touch other potentials, causing the line to short-circuit and trip. Furthermore, the insulated guide wires need to be manually pulled when installed and retrieved, which is inconvenient and poses a risk of the insulated guide wires falling from a height. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an insulated lead wire reel that can conveniently and safely install and recycle insulated lead wires.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An insulated lead-acid reel includes an upper reel, a lower reel, and a base. The upper reel, lower reel, and base are stacked sequentially in a vertical direction. The upper reel and lower reel rotate independently relative to each other. The upper reel and lower reel have concentric through holes at their rotation centers. The bottom of the grooves of the upper reel and lower reel has a cable path extending to the through holes. The side of the base away from the lower reel has a crossarm fixing structure that is fixedly connected to an external crossarm.

[0007] The upper reel, lower reel, and base are made of insulating material.

[0008] The beneficial effects of this invention are as follows: the insulated lead wire passes through perforations and cable trays, and its two ends are wound around the upper and lower reels respectively. The upper and lower reels rotate relatively independently, and both can independently release and retract the wire. The base is rotatably connected to the lower reel, and the rotation of the lower reel does not affect the base. The base is fixedly connected to the crossarm to prevent the insulated lead wire reel from falling from a height. Attached Figure Description

[0013] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0014] Please refer to Figure 1 as well as Figure 2 This invention provides an insulated drain wire reel, including an upper reel, a lower reel, and a base. The upper reel, lower reel, and base are stacked sequentially in a vertical direction. The upper reel and lower reel rotate independently relative to each other. The upper reel and lower reel have concentric through holes at their rotation centers. The bottom of the grooves of the upper reel and lower reel have a wire routing path extending to the through holes. The side of the base away from the lower reel has a crossarm fixing structure that is fixedly connected to an external crossarm.

[0015] The upper reel, lower reel, and base are made of insulating material.

[0016] As can be seen from the above description, the beneficial effects of the present invention are as follows: the insulated guide wire passes through the perforation and the wire routing groove, and its two ends are respectively wound around the upper reel and the lower reel. The upper reel and the lower reel rotate relatively independently, and the two can independently release and retract the wire. The base is rotatably connected to the lower reel, and the rotation of the lower reel does not affect the base. The base is fixedly connected to the crossarm to prevent the insulated guide wire reel from falling from a height.

[0017] Furthermore, the crossbeam fixing structure includes a slide rail and two slots that can slide along the slide rail. The slots include a U-shaped portion with the opening of the U-shaped portion facing away from the base.

[0018] As described above, the slots slide along the slide rail, which can adjust the relative distance between the slots to accommodate crossarms of different distances.

[0019] Furthermore, the slot also includes a buckle, one end of which is rotatably connected to one end of the U-shaped portion, and the other end is detachably fixedly connected to the other end of the U-shaped portion.

[0020] As described above, the buckle ensures the connection between the slot and the crossbar, preventing the risk of falling from a height.

[0021] Furthermore, a support column is included between the upper and lower reels. The support column is made of insulating material and has a through hole concentric with the through holes on the upper and lower reels. A circular rotating shaft is fixed to the through hole of the support column. The two ends of the rotating shaft are respectively inserted into the through holes of the upper and lower reels and do not extend to the cable routing path. The upper and lower reels are rotatably connected to the rotating shaft through a bearing structure.

[0022] As described above, when using the device, open the buckle, insert the two crossarms into the U-shaped part, and then lock the buckle onto the U-shaped part to prevent the insulated lead wire reel from falling.

[0023] Furthermore, the support column is made of epoxy resin fiberglass.

[0024] As described above, epoxy resin fiberglass has excellent insulation properties and mechanical strength, which can meet the needs of power maintenance operations.

[0025] Furthermore, the upper and lower reels have lead clamps at the end of the cable tray near the cable groove.

[0026] As described above, after the insulated guide wire is in place, the two ends of the insulated guide wire are fixed with a wire clamp to prevent the insulated guide wire from slipping along the wiring path during use and causing inconvenience.

[0027] Furthermore, the upper reel, lower reel, and base are made of epoxy resin fiberglass.

[0028] As described above, epoxy resin fiberglass has excellent insulation properties and mechanical strength, which can meet the needs of power maintenance operations.

[0029] This invention is applied to uninterrupted power maintenance work, and provides a bypass circuit for the cables at both ends of the crossbar.

[0030] Example 1

[0031] Please refer to Figure 1-2 An insulated drain wire reel of this embodiment includes an upper reel 1, a support column 3, a lower reel 4, a base 5, and a movable slot 6.

[0032] The upper reel 1, support column 3, lower reel 4, and base 5 are all disc-shaped. They are stacked from top to bottom, with their centers on the same straight line. A through hole 8 of the same diameter is opened in the center of the upper reel 1, support column 3, lower reel 4, and base 5. A wire groove 9 is opened on the outer periphery of the upper reel 1 and lower reel 4. A wire channel 7 extending to the through hole 8 is opened at the bottom of the wire groove 9 of the lower reel 4 of the upper reel 1, so that the wire groove 9 of the upper reel 1 and the lower reel 4 are connected. The insulated lead wire can pass through the wire channel 7 and the through hole 8, and its two ends are wound on the upper reel 1 and the lower reel 4 respectively.

[0033] Both cable trays 7 are equipped with lead wire clamps at one end near the bottom of the tray. After the insulated lead wires are in place, the lead wire clamps are used to fix the insulated lead wires at both ends to prevent the insulated lead wires from sliding along the cable trays 7 during use and causing inconvenience.

[0034] The upper reel 1 is rotatably connected to the support post 3, the lower reel 4 is rotatably connected to the support post 3, and the lower reel 4 is rotatably connected to the base 5. Thus, the upper reel 1 and the lower reel 4 can rotate independently relative to the support post 3, allowing the two ends of the insulated lead wire to be independently released and retrieved. When the lower reel 4 rotates, the base 5 does not rotate and is stably placed on the crossarm of the pole.

[0035] Specifically, in this embodiment, a circular rotating shaft 2 is fixed in the perforation 8 on the support column 3. The two ends of the rotating shaft 2 are inserted into the upper reel 1 and the lower reel 4, and neither end of the rotating shaft 2 extends to the cable routing 7. The upper reel 1 and the lower reel 4 are rotatably connected to the rotating shaft 2 through a bearing structure.

[0036] It is worth noting that the rotating shaft 2 and bearing structure in this embodiment are only one implementation method. Its purpose is to realize the relative rotation between the upper reel 1 and the lower reel 4 so as to achieve independent wire feeding. Other rotation methods can also be used, and this invention is not limited to this.

[0037] The lower side of the base 5 has a crossarm fixed connection. Specifically, the crossarm fixing structure has a slide rail with two slots 6 that are adapted to the crossarm. The slots 6 can slide relative to each other along the slide rail to adjust the relative distance between the slots 6 to accommodate crossarms of different distances.

[0038] Specifically, the card slot 6 has a semi-enclosed structure, which includes a U-shaped part and a buckle. The opening of the U-shaped part faces downward. One end of the buckle is rotatably connected to one end of the U-shaped part, and the other end is detachably fixedly connected to the other end of the U-shaped part. When in use, the buckle is opened, the two crossarms are inserted into the U-shaped part respectively, and then the buckle is locked on the U-shaped part to prevent the insulated guide wire reel from falling.

[0039] The upper reel 1, the support column 3, the lower reel 4, and the base 5 are all made of insulating materials. In this embodiment, epoxy resin fiberglass is specifically used, which has excellent insulation performance and mechanical strength and can meet the needs of power maintenance operations.

[0040] In summary, the present invention provides an insulated guide wire reel, which is equipped with an independently rotating upper reel and a lower reel. The two ends of the insulated guide wire are respectively wound in the wire grooves of the upper reel and the lower reel. The insulated guide wire reel can be detachably fixedly connected to the crossarm, realizing convenient and safe installation and retrieval of the insulated guide wire. The lead wire clamp prevents the insulated guide wire from sliding and causing inconvenience, and the adjustable distance slot can adapt to crossarms of different widths.

[0041] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
