Description

Technical Field

[0001] This application relates to the field of cable terminal well technology, specifically to a multifunctional integrated cable terminal well structure. Background Technology

[0002] In power systems, cable terminal wells are facilities that connect underground cables to overhead lines. Their main function is to provide installation space for cable terminals and to protect, support, and fix the cables. With the continuous development of power engineering, the performance requirements for cable terminal wells are becoming increasingly stringent, requiring good structural stability to withstand external loads and prevent cable displacement.

[0003] Currently, the construction and installation process of traditional cable terminal wells is as follows: First, during the concrete pouring stage of the terminal well, simple metal supports are pre-installed on the well wall, or circular installation holes are reserved at designated locations. After the main structure of the terminal well is cured, the protective pipe is aligned with the reserved hole, and the gap between the protective pipe and the hole is filled and fixed by pouring concrete on site to ensure the initial positioning of the protective pipe. After the poured concrete has completely solidified, the cable is inserted from one end of the protective pipe and slowly pushed to the other end, so that the cable terminal extends to the connection area inside the terminal well. Finally, the cable is connected to the terminal equipment of the overhead line or other power components through terminals, insulation accessories, etc., to form a complete power transmission path.

[0004] However, the positioning accuracy of the protective pipe depends on the construction quality of the inner wall of the terminal well. If the surface flatness of the well wall deviates significantly during concrete pouring, or if the center axis of the reserved hole is tilted, the pre-set simple support is prone to tilting with the shape of the well wall, causing the axis of the subsequently fixed protective pipe to shift. At the same time, in the traditional process, the positioning of the terminal rod and the protective pipe are independent of each other, and the two need to be calibrated separately. Construction personnel need to repeatedly adjust the position to ensure coaxiality as much as possible, which can easily prolong the construction period. Therefore, it is necessary to provide a multi-functional integrated cable terminal well structure to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved in this application is: to provide a multifunctional integrated cable terminal well structure, which solves the problem that in the construction of some cable terminal wells, the positioning accuracy of the protective pipe is easily deviated due to the construction quality of the inner wall of the terminal well, and the independent positioning of the terminal rod and the protective pipe requires separate calibration and repeated adjustment, resulting in an extension of the construction period.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] like Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, this application provides a multifunctional integrated cable terminal well structure, including an embedded terminal well installation structure. The embedded installation structure includes a terminal well body 1, which has sufficient internal space. A cable pole 11 is fixedly installed inside the terminal well body 1. The cable pole 11 supports the cable and can support the cable to a suitable height and position within the terminal well, making the cable routing within the terminal well more reasonable. This prevents the cable from excessively bending or tangling due to its own weight or external factors, ensuring the normal shape of the cable and the stability of power transmission.

[0036] A pole base 12 is fixedly installed at one end of the cable pole 11. The pole base 12 is the supporting structure of the cable pole 11. It provides a stable bottom support for the cable pole 11, so that the cable pole 11 can maintain a stable posture under various working conditions, such as soil pressure and cable tension, and provides a solid foundation for cable support.

[0037] like Figures 2-4As shown, a transition assembly 2 is installed on the terminal well body 1. The transition assembly 2 includes a base 21 that is bolted to the terminal well body 1. The base 21 serves as the connection structure between the transition assembly 2 and the terminal well body 1. The bolted connection not only ensures the firmness of the connection between the base 21 and the terminal well body 1, making it less prone to loosening or displacement when bearing the weight of various components and external forces, but also facilitates installation, disassembly, and subsequent maintenance. When it is necessary to inspect the transition assembly 2 or other related components, the base 21 can be separated from the terminal well body 1, improving the convenience of maintenance.

[0038] Multiple sets of positioning pins 211 are fixedly installed on the main body 1 of the terminal well. Positioning holes 212 adapted to the positioning pins 211 are provided on the base 21. The cooperation between the positioning pins 211 and the positioning holes 212 can position the base 21 when it is installed, ensuring that the base 21 is installed accurately on the main body 1 of the terminal well. This prevents the subsequent components from being misaligned due to installation position deviation, thus affecting the stability of the entire cable terminal well structure and the compatibility between the components.

[0039] An adapter ring 22 is fixedly installed in the center of the base 21. The adapter ring 22 is fixedly connected to one end of the cable pole 11. The adapter ring 22 enables a reliable connection between the base 21 and the cable pole 11, allowing the cable pole 11 to be stably connected to the base 21, thereby forming a stable connection with the terminal well body 1. Three sets of positioning cylinders 23 are fixedly installed at both ends of the base 21. The positioning cylinders 23 are structures for pipe installation and positioning, used to provide an interface for pipe installation.

[0040] One end of the positioning cylinder 23 extends to the lower part of the base 21. This structural design increases the connection depth between the positioning cylinder 23 and the base 21, further improving the stability of the positioning cylinder 23 installation. This makes the positioning cylinder 23 more stable when bearing the weight of the pipe and cable, and less prone to loosening or deformation. Multiple adapter blocks 24 connected to the positioning cylinder 23 are fixedly installed on the adapter ring 22. The adapter blocks 24 connect the adapter ring 22 and the positioning cylinder 23, forming a stable connection between the adapter ring 22 and the positioning cylinder 23. This enhances the overall structural stability of the adapter assembly 2 and ensures that the adapter ring 22 and the positioning cylinder 23 will not easily displace relative to each other when subjected to external factors such as soil settlement and cable tension. This ensures that the adapter assembly 2 has a stable and reliable function for adapting to each component.

[0041] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a reinforcement component 3 is installed on the positioning cylinder 23. The main function of the reinforcement component 3 is to stabilize and reinforce the cable pole body 11 and pipe body and other components, preventing them from shifting or shaking during operation, and ensuring the safety and stability of the cable in the terminal well. The reinforcement component 3 includes a protective tube 31 installed in multiple positioning cylinders 23. The protective tube 31 is used to protect the cable passing through it. It can wrap the cable inside to prevent the cable from being damaged by external mechanical damage, such as collision or squeezing. At the same time, it can also prevent water, dust and other impurities from entering to a certain extent, protecting the cable insulation layer and extending the service life of the cable.

[0042] Multiple sets of limiting plates 32 are fixedly installed at one end of the protective tube 31. Each positioning cylinder 23 is provided with a limiting groove 321 that matches the limiting plate 32. The cooperation between the limiting plate 32 and the limiting groove 321 can limit the installation of the protective tube 31 on the positioning cylinder 23, ensuring the accuracy of the installation position of the protective tube 31 and enabling the protective tube 31 to dock with the positioning cylinder 23. The protective tube 31 and the positioning cylinder 23 are connected by bolts. The bolt connection ensures the firmness of the connection between the protective tube 31 and the positioning cylinder 23, so that the protective tube 31 can be stably installed on the positioning cylinder 23 and is not easy to loosen or fall off when bearing the weight of the cable and possible external forces.

[0043] A detachable waterproof heat shrink tubing 33 is installed at the other end of the protective tube 31. The detachable waterproof heat shrink tubing 33 can waterproof the end of the protective tube 31. It can tightly wrap around the end of the protective tube 31 to reduce the entry of rainwater and other liquids into the interior from the end of the protective tube 31. It plays a good role in waterproofing the end of the cable passing through it, preventing the cable from insulation damage and other faults caused by water immersion, and ensuring the safe operation of the cable. Moreover, the detachable design makes it easy to quickly remove the waterproof heat shrink tubing 33 when the cable needs to be inspected or replaced, which improves the convenience of maintenance.

[0044] Two sets of symmetrically arranged main reinforcing plates 34 are bolted to the cable pole body 11. Multiple sets of reinforcing rings 35 slide on the main reinforcing plates 34, and the reinforcing rings 35 can slide along the cable pole body 11. The reinforcing rings 35 can slide on the main reinforcing plates 34, which makes it easy to flexibly adjust the position of the reinforcing rings 35 according to the actual cable layout, the position of the protective pipe 31, etc., to adapt to different reinforcement requirements. The reinforcing rings 35 are connected to the main reinforcing plates 34 by bolts. The bolt connection has good connection strength and can ensure that the reinforcing rings 35 are firmly fixed on the main reinforcing plates 34 after being adjusted to the appropriate position, and will not easily slide.

[0045] Multiple sets of reinforcing frames 36 that can slide along the protective tube 31 are fixedly installed on the reinforcing ring 35. The reinforcing frames 36 serve to connect the reinforcing ring 35 and the protective tube 31. By sliding along the protective tube 31, the position of the reinforcing frame 36 on the protective tube 31 can be adjusted, thereby better reinforcing the protective tube 31. When the protective tube 31 is subjected to external force, it can be supported and constrained by the reinforcing frame 36, and is not prone to displacement or shaking.

[0046] Auxiliary reinforcing plates 37 are bolted to each of the protective pipes 31. The auxiliary reinforcing plates 37 provide a sliding and fixed support structure for the reinforcing frame 36. The reinforcing frame 36 can slide along the auxiliary reinforcing plates 37, increasing the flexibility of the reinforcing frame 36's position adjustment. The reinforcing frame 36 and the auxiliary reinforcing plates 37 are connected by bolts, which ensures the firmness of the reinforcing frame 36 fixed on the auxiliary reinforcing plates 37. This allows the reinforcing frame 36 to stably reinforce the protective pipe 31. In turn, through the cooperation of the main reinforcing plate 34, the reinforcing ring 35, the reinforcing frame 36, and the auxiliary reinforcing plates 37, a stable reinforcement structure for the cable pole 11 and the protective pipe 31 is formed, effectively preventing the cable pole 11 and the protective pipe 31 from shifting or shaking when affected by external factors, thus ensuring the stability of power transmission.

[0047] like Figures 9-11 As shown, in addition to the above-mentioned embedded installation method, this multi-functional integrated cable terminal well structure can also adopt an enclosed installation method. This method can ensure the accurate positioning of the protective pipe in advance, reduce the need for later adjustments, enhance the support stability of the cable pole body 11, integrate the laying needs of multiple types of lines to improve space utilization, and at the same time strengthen waterproof performance and structural load-bearing capacity, making it suitable for specific engineering scenarios.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
