Description

Technical Field

[0001] This utility model belongs to the field of power grid circuit cable laying technology, and specifically relates to a power grid transmission line wire laying device. Background Technology

[0002] Power transmission lines are a crucial component of the power system, primarily used to transmit electricity generated by power plants to various substations or directly to users. They act like "highways" for power transmission, typically consisting of conductors, insulators, towers, hardware, and foundations. Conductors are generally made of highly conductive materials such as copper and aluminum, their function being to conduct strong currents. Insulators suspend and support the conductors, insulating them from the towers and preventing current leakage to the ground, thus ensuring transmission safety. Towers are the supporting structures for transmission lines, and come in various forms, such as iron towers and concrete poles, capable of supporting the conductors, insulators, and hardware. The weight of the poles must be supported, and they must withstand external forces in various environments, such as strong winds and icing. The fittings are mainly used to connect, fix and protect components such as conductors and insulators, ensuring that their positions are accurate and the connections are firm. The foundation is the base of the pole, ensuring that the pole stands stably on the ground and provides solid support for the entire transmission line. Transmission lines can be divided into high-voltage transmission lines, ultra-high-voltage transmission lines and extra-high-voltage transmission lines according to their voltage levels. Lines of different voltage levels are suitable for different transmission distances and transmission capacities, thus forming a complex and efficient power grid transmission network to realize long-distance and large-scale transmission of electrical energy. Currently, in the application of power grid transmission lines, it is usually necessary to lay out the lines. Existing lines often have a lot of redundant wires during the laying process. These redundant wires are typically bundled with tape and then pasted inside the wiring box. However, existing wiring boxes usually lack the function of retracting these redundant wires. For example, Chinese patent publication number "CN221688007U" discloses a power line wiring box, which includes a box body. Air inlets are located on both sides of the lower part of the box body, and a first filter is installed at each air inlet. An air outlet is located at the rear of the box body. An air intake channel communicating with the air inlets is located inside the box body. The air intake channel is arranged obliquely and symmetrically on both sides, guiding the airflow downwards. Multiple dust suction components are located on both sides of the air intake channel, and an air outlet is located in the middle. This provides a power line wiring box with a reasonable structural arrangement, which can effectively filter dust in the airflow while maintaining ventilation, keeping the inside of the box clean and ensuring long-term operation of the lines. The aforementioned cabling boxes have a significant functional deficiency in practical applications: they lack the ability to effectively wind up excess cabling. In daily use, we often see that when the cable length exceeds the actual requirement, the excess cable is often left haphazardly placed or simply wrapped with tape. This seemingly temporary solution causes numerous problems over time. First, the messy cable significantly reduces cabling efficiency, making the entire process cumbersome and difficult to manage, increasing both time and labor costs. Second, for subsequent maintenance and repair work, these messy cables... Messy wiring is undoubtedly a huge obstacle. Maintenance personnel need to spend a lot of time searching for fault points among numerous tangled wires, which seriously reduces the efficiency of inspection and maintenance. More seriously, if the wiring is in a messy state during the wiring process, circuit entanglement is very likely to occur, which may lead to wire breakage or even short circuits and other dangerous accidents. This will not only affect the normal operation of the power system, but may also threaten the safety of equipment and personnel. Therefore, in order to improve the performance of wiring boxes and ensure the stable operation and safety of the power system, it is urgent to carry out targeted improvements and designs on existing technologies to solve a series of problems caused by messy wiring.

[0014] Example refer to Figures 1 to 4 This embodiment of a power grid transmission line wire arrangement device includes a base plate 1, a housing 2 fixedly installed on the top of the base plate 1, slide rails 3 fixedly installed on both sides of the top of the housing 2, a slide plate 4 slidably connected inside the slide rails 3, a frame 5 fixedly installed at the bottom of the slide plate 4, a winding mechanism 6 fixedly installed at both the upper and lower ends of the inner side of the frame 5, a door 7 hinged to the front of the housing 2, and cable routing holes 8 equally spaced on both sides of the housing 2. The winding mechanism 6 includes a frame 61, which is fixedly installed in the middle of the frame 5. Outer shells 62 are fixedly installed at equal intervals on both sides of the frame 61. Elastic members 63 are fixedly installed inside the outer shells 62, and winding wheels 64 are fixedly installed on the inner side of the elastic members 63. A through slot 65 is provided in the middle of the winding wheels 64. The base plate 1 provides a stable foundation support for the entire device. The housing 2 serves to protect internal components and house wiring. The equally spaced wiring holes 8 on both sides facilitate the entry and exit of wiring. The slide rail 3 on the top of the housing 2 cooperates with the sliding plate 4, allowing the frame 5 and the winding mechanism 6 to slide easily. This is extremely convenient for installation and maintenance. The operator can easily pull out the winding mechanism 6 for operation or maintenance. In the winding mechanism 6, the frame 61 serves as the core support structure, and the shells 62 distributed at equal intervals on both sides provide installation positions for the elastic element 63 and the winding wheel 64. The setting of the elastic element 63 gives the winding wheel 64 a certain elastic buffering capacity when winding the line, which can adapt to different tension conditions and protect the line from excessive pulling. The through slot 65 in the middle of the winding wheel 64 provides a path for the line to be wound, making it convenient for the line to be neatly wound on the winding wheel 64, realizing the orderly winding and management of the wire, improving the standardization and reliability of the power grid transmission line wire layout, and facilitating subsequent maintenance and management work.

[0015] refer to Figures 2-4The elastic element 63 includes a torsion spring 631, which is fixedly installed inside the housing 62. The inner sides of the two torsion springs 631 are fixedly connected to the two sides of the take-up reel 64, respectively. The elastic element 63 also includes a connecting rod 632, which is fixedly installed at the front end of the take-up reel 64. The end of the connecting rod 632 passes through the housing 62 at the front end and is fixedly installed with an operating handle 633. As the core elastic element, the torsion spring 631 is fixedly installed inside the housing 62 and connected to the two sides of the take-up reel 64, providing elastic support and reset power for the take-up reel 64. When the line is being wound up, the torsion spring 631 can store energy. When encountering external force such as strong wind blowing the line, the spring 631 can release its elasticity. The design provides a buffer, effectively preventing the line from breaking due to excessive tension, thus protecting the line's safety and extending its service life. The connecting rod 632 facilitates operation; it is fixedly connected to the front end of the winding wheel 64 and has an operating handle 633 installed through the end of the housing 62. This allows operators to manually control the rotation of the winding wheel 64 by turning the operating handle 633, enabling the winding and unwinding of the line. This manual control method is simple and direct, allowing for flexible adjustment of the winding degree according to actual needs in different scenarios, adapting to various complex wire layouts, and improving the ease of operation and practicality of the entire power grid transmission line wire layout device.

[0016] refer to Figures 1-2 Mounting holes 9 are provided at all four corners of the chassis 2. These mounting holes 9 are countersunk holes. Sealing rings 10 are fixedly installed on the outside of the cable routing holes 8. The overall cross-sectional shape of the sealing rings 10 is arc-shaped. A fixed side plate 11 is hinged to the outer end of the chassis door 7. Both the upper and lower ends of the fixed side plate 11 are threaded with fixing screws 12. The countersunk mounting holes 9 at the four corners allow the bolt heads to be recessed into the holes during chassis 2 installation, making the surface of chassis 2 smoother. This not only improves aesthetics but also avoids potential collisions or scratches caused by protruding bolt heads in space-constrained environments. It also helps improve the stability and tightness of the installation. The sealing rings 10 are fixedly installed on the outside of the cable routing holes 8. The sealing ring 10 has an overall arc-shaped cross-section. When the wire passes through the wiring hole 8, the sealing ring 10 can tightly fit the wire and deform, thereby effectively squeezing and sealing the wire to prevent dust, moisture and other impurities from entering the inside of the chassis 2. This ensures a good working environment for the wires inside the chassis 2 and improves the safety and service life of the wires. The hinged fixed side plate 11 of the door 7 and the fixed screws 12 with threads at both ends make the closing of the door 7 more secure and reliable. By simply twisting the fixed screws 12 to fix them in the corresponding positions, the door 7 can be ensured to close tightly, effectively protecting the wires and equipment inside the chassis 2. At the same time, this design is also easy to operate, improving the convenience and overall reliability of the device during use.

[0017] refer to Figures 1-3 A square groove 13 is provided on the outer side of the chassis 2. The outer end of the fixed side plate 11 is inserted into the inner side of the square groove 13. Limiting holes 14 are provided at both the upper and lower ends of the square groove 13. The end of the fixing screw 12 is inserted into the limiting hole 14. The fixing screw 12 is a hand-tightening screw. The square groove 13 on the outer side of the chassis 2 provides an accurate insertion position for the outer end of the fixed side plate 11, so that the fixed side plate 11 can accurately fit with the chassis 2 when the door 7 is closed, which enhances the stability and sealing of the door 7 when closed. The limiting holes 14 at both the upper and lower ends of the square groove 13 cooperate with the fixing screw 12 at the outer end of the fixed side plate 11. When the end of the fixing screw 12 is inserted into the limiting hole 14, the fixing side plate 11 can be inserted into the limiting hole 14. When the enclosure is inside, the position of the door 7 can be accurately locked to prevent accidental opening during use, ensuring the safety of the wiring and equipment inside the enclosure 2. Moreover, the fixing screw 12 is set as a hand-tight screw, which greatly improves the convenience of operation. Users do not need to use other tools and can easily tighten or loosen the fixing screw 12 manually, which can conveniently and quickly realize the opening and closing of the door 7. Whether in daily line maintenance or equipment inspection, it can save time and effort, improve work efficiency, and also reflect the humanized and practical design, making the entire power grid transmission line wiring device more convenient and reliable in use.

[0018] Operating principle and advantages: By setting up the winding mechanism 6, during actual use, the cable can be passed through the cable routing hole 8 on one side of the housing 2 into the interior of the housing 2. Then, by turning the operating handle 633, the winding wheel 64 is rotated. During this process, the rotation of the winding wheel 64 compresses the torsion spring 631, causing the torsion spring 631 to be in a contracted state. At this time, the cable is passed through the through slot 65 and then out through the cable routing hole 8 on the other side. Afterwards, the operating handle 633 is released, and the torsion spring 631 returns to its original position, thereby driving the winding wheel 64 to rotate. When the winding wheel 64 rotates, it can cause the cable to be wound around its outer surface, thus effectively removing excess cable. When the cable is wound up, it will automatically rotate the winding wheel 64 when strong winds blow it. At this time, the spring force generated by the retraction and reset of the torsion spring 631 can provide good buffer protection for the entire cable, preventing the cable from breaking due to excessive pressure. At the same time, the overall wiring is in a more compact state, reducing friction and pulling between the cables, which can significantly improve the service life of the cable. Moreover, the independent winding of each cable can effectively prevent the cables from getting tangled, which provides great convenience for subsequent inspection and maintenance work. Maintenance personnel can more clearly and quickly find the cables that need to be dealt with, improving work efficiency. By installing a sealing ring 10 on the chassis 2, effective sealing of the wiring hole 8 can be achieved. When the cable passes through the wiring hole 8, the cable will compress the sealing ring 10 inside the wiring hole 8, causing it to deform. After the sealing ring 10 deforms, it can compress and seal the cable inside the wiring hole 8, thus ensuring that the entire wiring inside the chassis 2 is in a good sealed state. This sealing state can effectively prevent external factors such as dust and moisture from corroding the wiring, further improving the service life of the wiring. At the same time, during use, the chassis 2 not only can store and protect excess wiring, but also has many other advantages. During overall use, the elasticity can be flexibly adjusted according to the degree of compression of the torsion spring 631 by turning the operating handle 633, which can well adapt to different wiring. The device is designed to provide suitable tension for the winding of the wiring. During use, it employs a sliding plate 4 and a slide rail 3 in conjunction with the mounting frame 5. This ingenious design allows for quick and easy removal of the winding mechanism 6 from inside the housing 2, saving time and manpower during both the initial wiring installation phase and subsequent maintenance. Furthermore, the hinged side plate 11 on the housing door 7, along with the fixing screw 12, allows for stable closure of the housing door 7 simply by twisting the fixing screw 12 and inserting it into the limiting hole 14. The operation is simple and quick. The addition of a hand-tightening screw further enhances the ease of use, making it accessible to both professional technicians and ordinary users, greatly facilitating power wiring work.
