Description

Technical Field

[0001] This utility model relates to the field of cable trough technology, specifically to an underground cable trough structure. Background Technology

[0002] Cables are wire products used to transmit power, signals, and data. A cable consists of one or more insulated wires, which are then covered with a protective layer. They are flexible, easy to bend, and easy to install, and are widely used in various fields such as power, communications, construction, railways, aviation, and home appliances.

[0003] Chinese patent discloses an underground cable protection trough (authorization announcement number CN216794528U), which includes a trough body with a U-shaped cross-section. A connecting plate is provided at the opening of the trough body, and a protective cover is provided on the trough body. The protective cover has a through-slot structure, and the connecting plate abuts against the side wall of the protective cover. This underground cable protection trough can deeply bury cables, which facilitates the troubleshooting and maintenance of cables, and effectively protects cables and extends their service life.

[0004] In the aforementioned patented technology, the installation and restraint of the cable are achieved through a receiving platform and anti-detachment strips. However, after the cable is placed inside the receiving platform, the platform does not have a clamping and fixing effect on the cable, which may cause the cable to shake inside the platform, resulting in unstable installation and potential wear. Based on this, the solution is further improved. Utility Model Content

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose. Example

[0029] Please see Figures 1-9 In this embodiment, a buried cable trough structure is provided, including a trough body 1 and a trough cover 2. The trough cover 2 is installed on the upper end of the trough body 1, and the two are inserted together. A sealing structure is provided between the two. At the same time, the cross-section of the trough body 1 and the trough cover 2 is a U-shaped structure and an inverted U-shaped structure, respectively. After the two are inserted together, their internal space is used to place the cable. The sealing structure can prevent underground soil and water from entering the interior of the trough body 1, keeping it dry and clean, which is conducive to the long-term placement of the cable.

[0030] Multiple support mechanisms 3 are provided inside the tank 1. The support mechanisms 3 are distributed along the length of the inner cavity of the tank 1. The support mechanisms 3 are used to fix the cable. Moreover, in the support mechanism 3 of this application, the cable can be clamped and fixed to prevent it from moving inside the tank 1 and causing friction, which would damage the cable.

[0031] Specifically, the sealing structure includes a sealing groove 11, a sealing gasket 12, and an insert 21. Two sealing grooves 11 are symmetrically arranged on the left and right sides of the upper end of the groove body 1. Each sealing groove 11 has a sealing gasket 12 on both the left and right side walls. The insert 21 is inserted into the sealing groove 11 and is negatively matched with the two sealing gaskets 12. The insert 21 is fixed to the bottom of the groove cover 2. When installing the groove cover 2, the insert 21 is aligned with the sealing groove 11, and then the groove cover 2 is pressed down so that the insert 21 is inserted into the sealing groove 11. At this time, the insert 21 will squeeze the sealing gaskets 12 on both sides to improve the sealing performance. Conversely, the groove cover 2 is pulled upward to disassemble the insert 21 from the sealing groove 11. (In this article, the groove body 1 is a section of the overall cable groove structure. Its two ends can be sealed by other means, such as concrete, to maintain a dry environment inside the groove body 1. This is hereby noted.)

[0032] The bottom of the tank 1 is provided with multiple bases 13, and the support mechanism 3 is threadedly installed in the base 13. The threaded installation makes the support mechanism 3 detachable, which is convenient for replacement and maintenance. The support mechanism 3 includes a support seat 31, which is U-shaped and has a bottom post 32 at its bottom. The lower end of the bottom post 32 has a threaded post 33, which is adapted to the base 13 with internal threads. The two are threadedly connected to each other, so as to realize the detachability of the support mechanism 3.

[0033] The support base 31 has screw holes 34 on its left and right side walls, and screw rods 35 are installed in the screw holes 34. A nut 36 is fitted on the end of the screw rod 35 located outside the support base 31, and the end of the screw rod 35 located inside the support base 31 is rotatably connected to a movable plate 37. The movable plate 37 is slidably connected to the inner wall of the support base 31. When the screw rod 35 is rotated, it can move in the screw hole 34, moving towards or away from the support base 31, thereby driving the movable plate 37 to move accordingly. After the position of the movable plate 37 is adjusted, the nut 36 is tightened, which serves as a limit.

[0034] The bottom of the movable plate 37 is provided with a slider 38, and correspondingly, a groove 39 is provided on the inner wall of the support base 31. The slider 38 is located in the groove 39. When the movable plate 37 moves, the two slide against each other and at the same time play a limiting role.

[0035] Meanwhile, multiple spring posts 391 are provided on the side of the movable plate 37 away from the screw 35. One end of the spring post 391 is fixed with a clamping plate 392. The clamping plate 392 has an arc-shaped structure. When the movable plate 37 moves, the two arc-shaped clamping plates 392 in the support base 31 move closer or further away from each other, thereby clamping and fixing the cable between them. This can accommodate cables of different outer diameters and maintain the stability of the cable after installation.

[0036] In this utility model, the trough cover 2 and the trough body 1 are fixed by plugging and a sealing structure is provided between them. While facilitating disassembly, it also has a sealing function, which can effectively prevent underground water and soil from entering the space of the trough body 1, providing a good installation environment for cables. At the same time, the support mechanism 3 can clamp and fix cables of different outer diameters, preventing the cables from shaking in the support base 31, improving their placement stability and preventing wear.

[0037] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
