Description

Technical Field

[0001] This utility model relates to the field of power maintenance equipment technology, and more specifically, to a power maintenance wiring and power supply device. Background Technology

[0002] In the daily maintenance, fault repair, and some temporary power demand scenarios of the power system, it is often necessary to run wires from the power lines near the construction site. The traditional approach is to first cut off the power in the construction area and then have workers climb the power poles to connect the wires. This approach is time-consuming, labor-intensive, and dangerous. On the other hand, large-scale power outages will affect the power supply of nearby residents and businesses, resulting in economic waste.

[0003] Chinese patent application CN201922031948.4 discloses a power supply device for electrical maintenance wiring, including an outer cylinder and a wiring mechanism. Both ends of the outer cylinder have circular wiring through holes, and a sliding plate is slidably connected to the edge of the outer cylinder. A groove is formed on the inner sidewall of the outer cylinder, and the wiring mechanism is installed inside the outer cylinder. This device extends the original copper wiring piece laterally, ensuring that the connection point will not loosen during long-term power transmission, resulting in high connection stability. Furthermore, the wiring point is placed in a relatively enclosed internal cavity, isolating it from the outside environment, allowing for use even in rainy weather.

[0004] However, as can be seen from the accompanying drawings in the instruction manual, when the nearby power lines are high, it is inconvenient to connect the device via a support rod, thus requiring the wiring power supply device to be installed on the power lines. This makes it inconvenient to operate and use during actual installation and connection, affecting installation efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a power supply device for electrical maintenance wiring to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power maintenance wiring and power supply device, including an insulating outer cylinder. The bottom of the insulating outer cylinder has a hanging groove for connecting wires. By clamping the insulating outer cylinder onto the wires and attaching it to a conductive copper plate, power can be supplied via wiring. A conductive copper plate for current conduction is embedded in the top of the inner cavity of the hanging groove. A power supply line connected to the conductive copper plate is connected to one side of the insulating outer cylinder. Insulating and waterproof tapes are fixedly connected to the openings on both sides of the insulating outer cylinder to protect the hanging grooves on both sides. The insulating and waterproof tapes can wrap and protect the openings on both sides of the hanging grooves, thus providing waterproof protection and preventing rainwater from entering the interior of the insulating outer cylinder and affecting the wiring and power supply effect.

[0007] A first connecting cylinder and a fixed cylinder are fixedly connected to one side of the bottom of the insulating outer cylinder. The inner cavity of the insulating outer cylinder is provided with a clamping and fixing mechanism. The bottom of the fixed cylinder is provided with an auxiliary connecting mechanism for connecting and disassembling, which drives the clamping and fixing mechanism. The first connecting cylinder facilitates the connection of the support rod to the insulating outer cylinder, thereby suspending the insulating outer cylinder on the high-voltage power line, facilitating ground wiring and power supply, and making installation and use convenient. The clamping and fixing mechanism improves the safety of the insulating outer cylinder during installation, and the auxiliary connecting mechanism facilitates the operation and use of the clamping and fixing mechanism.

[0008] Preferably, an elastic strip is provided on the edge of the insulating waterproof tape away from the insulating outer cylinder, and the shape of the insulating waterproof tape is the same as the cross-sectional shape of the hanging groove. The insulating waterproof tape covers both sides of the hanging groove and plays a waterproof role.

[0009] Preferably, the clamping and fixing mechanism includes a pressing plate inserted into one side of the inner cavity of the hanging groove, a pull rope connected to one side of the pressing plate, and a protective sleeve fixedly connected to one side of the insulating outer cylinder at a position corresponding to the pull rope, the pull rope passing through the middle of the protective sleeve.

[0010] Preferably, a limiting plate is fixedly connected to one side of the extrusion plate, and a stabilizing rod is inserted into the middle of the limiting plate. A return spring is sleeved on the end of the stabilizing rod near the pull rope. The push of the limiting plate by the return spring causes the extrusion plate to extrude and fix the wire in the middle of the hanging groove, thereby improving the fixing effect. The stabilizing rod also improves the stability of the extrusion plate movement. Pulling the pull rope makes it easy to pull the extrusion plate.

[0011] Preferably, the auxiliary connection mechanism includes a rod inserted into the bottom of the fixed cylinder, a limit screw head fixedly connected to the top of the rod, and a spring sleeved on the top of the rod.

[0012] Preferably, a connecting plate is fixedly connected to the bottom of the insertion rod, a second connecting cylinder is fixedly connected to the bottom of the connecting plate, and the top of the connecting plate is fixedly connected to the end of the pull rope away from the extrusion plate.

[0013] Preferably, the bottom opening diameter of the second connecting cylinder is the same as that of the first connecting cylinder, and the inner cavity of the second connecting cylinder is the same as that of the first connecting cylinder. The second connecting cylinder is connected to the support rod to support the insulating outer cylinder, which is convenient for suspension connection. Pulling the second connecting cylinder drives the connecting plate to pull the pull rope, which makes it easy to generate a downward force on the extrusion plate, thereby moving the extrusion plate to the bottom of the wire to extrude and fix the wire. The spring pushes the limit screw head to generate a reset force on the connecting plate, which is convenient for reset use.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model firstly connects the second connecting cylinder to the support rod via a threaded connection, which facilitates the suspension of the insulating outer cylinder on the wire through the hanging groove via the support rod. By pulling the second connecting cylinder, the connecting plate is driven to pull the pull rope against the extrusion plate, causing one end of the extrusion plate to move out of the hanging groove, thereby placing the wire between the extrusion plate and the conductive copper plate. The push of the limit plate by the return spring allows the extrusion plate to press against the wire, completing the installation and fixing. The operation is simple, convenient for installation and use, and improves installation efficiency.

[0016] 2. This utility model also features a limit screw head that slides to connect with the fixed cylinder, allowing the connecting plate and the second connecting cylinder to move only up and down without rotating. This facilitates the connection of the support rod with the second and first connecting cylinders during disassembly, enabling easy disassembly and reuse. Furthermore, the insulating and waterproof tape protects both sides of the hanging groove, preventing rainwater from entering the middle of the groove and affecting the wire connection, thus improving the overall performance.

[0017] In summary, through the interaction of the above-mentioned multiple functions, the wiring power supply device can be easily installed on the power line, and the operation is simple, convenient to install and use, and the installation efficiency is improved. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As attached Figure 1-4 The power maintenance wiring and power supply device shown includes an insulating outer cylinder 1. The bottom of the insulating outer cylinder 1 has a hanging groove 2 for connecting wires. By clamping the insulating outer cylinder 1 onto the wires and attaching it to the conductive copper plate 3, power can be supplied via wiring. The top of the inner cavity of the hanging groove 2 is embedded with a conductive copper plate 3 for current conduction. A power supply line 4 connected to the conductive copper plate 3 is connected to one side of the insulating outer cylinder 1. Insulating waterproof tape 6 is fixedly connected to the openings on both sides of the insulating outer cylinder 1 to protect the hanging grooves 2 on both sides of the insulating outer cylinder 1. The insulating waterproof tape 6 can wrap and protect the openings on both sides of the hanging groove 2, playing a waterproof role and preventing rainwater from entering the interior of the insulating outer cylinder 1 and affecting the wiring and power supply effect.

[0025] The bottom side of the insulating outer cylinder 1 is fixedly connected to a first connecting cylinder 5 and a fixed cylinder 7. The inner cavity of the insulating outer cylinder 1 is provided with a clamping and fixing mechanism. The bottom of the fixed cylinder 7 is provided with an auxiliary connecting mechanism for connecting and disassembling the clamping and fixing mechanism. The first connecting cylinder 5 facilitates the connection of the support rod to the insulating outer cylinder 1, thereby suspending the insulating outer cylinder 1 on the high-voltage power line, facilitating ground wiring and power supply, and making installation and use convenient. The clamping and fixing mechanism improves the safety of the insulating outer cylinder 1 during installation, and the auxiliary connecting mechanism facilitates the operation and use of the clamping and fixing mechanism.

[0026] As attached Figure 1-4As shown, an elastic strip is provided on the edge of the insulating waterproof tape 6 away from the insulating outer cylinder 1. The shape of the insulating waterproof tape 6 is the same as the cross-sectional shape of the hanging groove 2. The clamping and fixing mechanism includes a compression plate 13 inserted into one side of the inner cavity of the hanging groove 2. A pull rope 14 is connected to one side of the compression plate 13. A protective sleeve 15 is fixedly connected to one side of the insulating outer cylinder 1 at a position corresponding to the pull rope 14. The pull rope 14 passes through the middle of the protective sleeve 15. A limit plate 16 is fixedly connected to one side of the compression plate 13. A stabilizing rod 17 is inserted into the middle of the limit plate 16. A return spring 18 is sleeved on one end of the stabilizing rod 17 near the pull rope 14. The auxiliary connecting mechanism includes a rod 8 inserted into the bottom of the fixing cylinder 7. A limit screw head 9 is fixedly connected to the top of the rod 8. A spring 10 is sleeved on the top of the rod 8. A connecting plate 11 is fixedly connected to the bottom of the rod 8. A second connecting cylinder 12 is fixedly connected to the bottom of the connecting plate 11. The top of the connecting plate 11 is fixedly connected to the end of the pull rope 14 away from the compression plate 13. Next, the bottom opening diameter of the second connecting cylinder 12 is the same as that of the bottom opening diameter of the first connecting cylinder 5, and the inner cavity of the second connecting cylinder 12 is the same as that of the first connecting cylinder 5. The two sides of the hanging groove 2 are covered by the insulating waterproof tape 6 to provide waterproofing. The push of the limiting plate 16 by the return spring 18 causes the pressing plate 13 to press and fix the wire in the middle of the hanging groove 2, improving the fixing effect. The stability of the pressing plate 13 is improved by the stabilizing rod 17. The pressing plate 13 can be easily pulled by pulling the pull rope 14. The second connecting cylinder 12 is connected to the support rod to support the insulating outer cylinder 1, which is convenient for suspension connection. Pulling the second connecting cylinder 12 drives the connecting plate 11 to pull the pull rope 14, which makes it easy to generate a downward force on the pressing plate 13, thereby moving the pressing plate 13 to the bottom of the wire to press and fix the wire. The push of the limiting screw head 9 by the spring 10 causes the connecting plate 11 to generate a reset force, which is convenient for reset.

[0027] The working principle of this utility model is as follows: When in use, the top end of the support rod is inserted into the interior of the second connecting cylinder 12 and threadedly connected to the second connecting cylinder 12. The insulating outer cylinder 1 is then suspended on the high-voltage wire, so that the high-voltage wire is located in the middle of the hanging groove 2. At this time, the high-voltage wire is located at the bottom of the extrusion plate 13. Then, the support rod is pulled, which in turn drives the pull rope 14 to pull the extrusion plate 13, so that one end of the extrusion plate 13 is moved out of the interior of the hanging groove 2. At this time, the high-voltage wire is in contact with the conductive copper plate 3. The second connecting cylinder 12 is then released, and the extrusion plate 13 is located at the bottom of the high-voltage wire, thus realizing the installation and fixation of the insulating outer cylinder 1. At the same time, the insulating waterproof tape 6 is used to protect the two sides of the hanging groove 2 from water.

[0028] When disassembly is required, connect the support rod to the first connecting cylinder 5 and the other support rod to the second connecting cylinder 12. Pull the second connecting cylinder 12 and move the first connecting cylinder 5 upward, thereby moving the insulating outer cylinder 1 upward, thus completing the disassembly of the insulating outer cylinder 1.
