Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power distribution engineering technology, and in particular relates to a power transmission line support device. Background Technology
[0002] Localized soil settlement can have significant negative impacts on underground power transmission lines. Soil settlement alters the density and structure of the underground soil, potentially causing deformation, bending, or breakage of the buried lines. The settlement process alters the relative position of the buried lines, leading to uneven tension and increased tensile or compressive stress, which may result in insulation damage, short circuits between conductors, or even complete line failure. Furthermore, soil settlement can cause compaction of the soil around the buried lines, reducing their heat dissipation capacity and causing overheating of the transmission lines, affecting the normal operation of the system. In extreme cases, settlement can threaten the safety of transmission lines, affecting the stability and reliability of power supply.
[0003] Currently, although areas of localized soil settlement can be preliminarily predicted and delineated, there is a lack of effective settlement monitoring methods for underground power transmission lines, resulting in numerous shortcomings and deficiencies. First, existing monitoring methods mainly rely on periodic manual on-site inspections, which cannot achieve real-time or continuous monitoring. This is not only inefficient but also time-consuming and labor-intensive. Manual inspections often require significant human and material resources and suffer from long inspection cycles and limited coverage. Second, due to the lack of real-time monitoring, settlement changes are often not detected in time, preventing preventative measures from being taken in advance, potentially causing serious damage to the transmission lines. Monitoring and maintenance work is difficult to be efficient and timely, and many potential safety hazards are not detected in their early stages, increasing the difficulty of later repairs. Finally, because damage caused by settlement often occurs after prolonged neglect or untimely monitoring, the cost of repair is high, increasing the economic burden of maintenance and potentially adversely affecting the stability of power supply. Utility Model Content
[0004] In view of the lack of effective real-time settlement monitoring methods for underground power transmission lines in existing technologies, which rely on manual surveys, resulting in low efficiency, time and labor costs, and easy monitoring delays, this utility model provides a power transmission line support device.
[0005] This utility model is implemented as follows: a power transmission line support device, characterized in that it includes axial support components, axial rib rods, and a pull wire sensor assembly. The axial support components have a V-shaped groove structure, and N axial support components are spaced apart along the axial direction of the power transmission line, with the power transmission line supported in the V-shaped groove. The axial support components are provided with axial rib insertion holes, and the axial rib rods pass through the axial rib insertion holes of the axial support components. The axial support components are provided with axial pull wire holes, and the pull wire of the pull wire sensor assembly passes through at least two axial pull wire holes of the axial support components, with both ends of the pull wire sensor assembly connected to the axial support components that have been penetrated and are located at the ends.
[0006] In the above technical solution, preferably, the axial support component is a V-shaped bracket, and the V-shaped groove of the V-shaped bracket forms an upward support for the transmission line.
[0007] In the above technical solution, preferably, the insertion holes are symmetrically arranged on both sides of the axial support component, and the axial rib is a metal rod that passes through the insertion holes.
[0008] In the above technical solution, preferably, the axial pull hole is located at the V-shaped apex of the axial support component.
[0009] In the above technical solution, preferably, the pull wire sensor assembly and the supporting component through which the pull wire of the pull wire sensor assembly passes constitute a detection unit, and N detection units are provided along the transmission line.
[0010] The protective support device for power transmission line wiring of this utility model has many significant advantages and good effects.
[0011] First, the device employs a simple and easily assembled / disassembled component combination, resulting in a simple structure that facilitates on-site installation and disassembly. It can quickly adapt to different wiring environments, reducing the difficulty of installation and maintenance. Due to its simple component structure and mature manufacturing process, the production cost is extremely low, making it highly economical and suitable for large-scale application in power transmission line deployment. Second, this device provides reliable support for buried power transmission lines. Even under the influence of environmental changes such as soil settlement, it can effectively maintain the bending strength of the power transmission lines, preventing deformation or damage and ensuring the stability and long-term reliability of the transmission lines.
[0012] Furthermore, this device integrates advanced cable bending detection capabilities, enabling real-time monitoring of transmission line conditions. When a cable bends and exceeds a set threshold, the device quickly detects it, automatically collects relevant data, and promptly issues an early warning signal. This intelligent monitoring not only ensures real-time feedback on line conditions but also effectively reduces the risk of line damage caused by soil settlement or other external factors. Early warnings enable more precise maintenance and repairs, avoiding the safety hazards and high maintenance costs caused by delayed manual inspections in traditional monitoring methods.
[0013] In summary, the application of this device not only improves the safety and stability of transmission lines, but also plays an important role in reducing maintenance costs and improving operational efficiency, demonstrating significant technical advantages and economic benefits.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.
[0018] To address the shortcomings of existing technologies, such as the lack of effective real-time settlement monitoring for buried power transmission lines and reliance on manual surveys which are inefficient, time-consuming, and labor-intensive, this invention provides a power transmission line support device. To further illustrate the structure of this invention, a detailed description is provided below in conjunction with the accompanying drawings:
[0019] Please see Figure 1 and Figure 2 A power transmission line support device includes an axial support component 1, an axial rib rod 2, and a guy wire sensor assembly.
[0020] The axial support components have a V-shaped groove structure. N axial support components are spaced apart along the axial direction of the transmission line 10, and the transmission line is supported in the V-shaped groove. In this embodiment, the axial support component is a V-shaped bracket, and the V-shaped groove of the V-shaped bracket forms an upward support for the transmission line. Insertion holes are symmetrically arranged on both sides of the axial support component. The V-shaped bracket is a thin plate component, formed by cutting a metal plate. Before the underground pipeline laying construction, the axial support components are inserted into the underground trench for burying the pipeline at predetermined intervals, with the V-shaped tips inserted into the soil for fixation. The axial support components extend axially to form a trench supporting the transmission line. This trench is laid in a foundation area prone to settlement and spans this area.
[0021] The axial support component is provided with axial reinforcing bar holes 3, through which axial reinforcing bars pass. The axial reinforcing bars are metal rods that pass through the reinforcing bar holes. The axial reinforcing bars and axial reinforcing bar holes are clearance-fitted, and the axial reinforcing bars connect the axial support component as a whole. The axial reinforcing bars traverse the easily settled soil area along the axial direction. The axial reinforcing bars connect the axial support component into a structure that increases the strength of the power transmission line support. Applied to soil areas prone to settlement, it can provide support and protection for power transmission lines under conditions of soil settlement.
[0022] The axial support component is provided with an axial pull wire hole 4. The pull wire of the pull wire sensor assembly passes through the axial pull wire holes of at least two axial support components, and both ends of the pull wire sensor assembly are respectively connected to the axial support components located at the ends through which the pull wire passes. The axial pull wire hole is located at the V-shaped apex of the axial support component.
[0023] The pull wire 5 of the pull wire sensor assembly can pass through the axial pull wire holes of all axial support components. The free end of the pull wire of the pull wire sensor assembly is fixed to one end of the axial support component, and the sensor body 6 of the pull wire sensor assembly is fixed to the other end of the axial support component. Alternatively, the pull wire sensor assembly and the support component through which the pull wire of the pull wire sensor assembly passes form a detection unit, and N detection units are provided along the transmission line.
[0024] A draw-wire sensor is a known displacement sensor widely used in various automated monitoring and control systems. Its working principle is based on transmitting the displacement of an object through a draw-wire, which then drives the sensor body (such as a potentiometer or encoder) inside the sensor to convert and output displacement data. A draw-wire sensor typically consists of a draw-wire, a sensor body, and a retrieval device. As the object displaces, the length of the draw-wire changes, thus affecting the sensor's measuring components and generating a corresponding electrical signal. This sensor has advantages such as simple structure, high accuracy, and fast response speed, making it suitable for applications requiring large-scale displacement detection, such as mechanical automation, aerospace, and engineering monitoring. In this embodiment, the draw-wire sensor acquires a signal based on the change in draw-wire length when the power transmission line bends due to soil settlement, and sends the signal to the host computer.
[0025] Please see Figure 3 To further enhance the support performance of this device, a collar 7 is installed at the end of the axial stiffener rod. The collar is connected to a vertically upward extending tie rod 8. The upper end of the tie rod is close to the ground and connected to an anchor plate 9, which is a flat plate.
[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
