[0001] This utility model relates to the field of cable support technology, specifically a pipeline built-in anti-corrosion cable support. Background Technology

[0002] Cable supports are widely used in urban power grid upgrades, power cable tunnels, cable trenches, and other projects to support and secure power cables, ensuring safe and reliable power transmission. Pipe-mounted anti-corrosion cable supports are devices used inside pipes to provide cable support and prevent corrosion. They effectively protect cables, extend their service life, and reduce the risk of electrical failures caused by corrosion.

[0003] For example, patent CN208299413U discloses a cable support suitable for use in pipelines, relating to the field of cable mounting equipment technology. This utility model includes support columns; two support columns installed side-by-side inside the pipeline; the two support columns are connected by at least one connecting rod; each support column has a support rod fixed to its circumferential side; the ends of the two support rods are connected to the inner wall of the pipeline via locking plates; a fixing mechanism is installed side-by-side along the central axis of the two support columns; and a horizontal beam is fixedly mounted on the fixing mechanism. This utility model, by utilizing the interconnection between the support columns and support rods as a support body, and using the fixing mechanism to install the horizontal beams for cable mounting side-by-side on the support columns, effectively avoids cable entanglement, completely eliminates eddy currents, reduces power loss, and facilitates cable installation, saving time and effort, thus possessing high market promotion value.

[0004] However, the cable support for pipes in this application lacks a convenient and adjustable limiting bracket inside, making installation cumbersome when dealing with cables of different quantities and sizes. Utility Model Content

[0005] The purpose of this utility model is to provide a pipeline built-in anti-corrosion cable bracket to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pipe-embedded anti-corrosion cable bracket, including an outer pipe, an upper sleeve installed on the surface of the outer pipe, a lower sleeve installed at the lower end of the outer pipe, a lower arc-shaped plate fixedly connected to the bottom of the inner part of the outer pipe, a vertical support welded to the top of the lower arc-shaped plate, a right mounting strip installed on the front end of the vertical support, a plurality of upper mounting holes opened inside the right mounting strip, a plurality of lower mounting grooves opened inside the right mounting strip, a plurality of U-shaped fixing seats installed on the side end of the right mounting strip, a first cross brace fixedly connected to the side end of the U-shaped fixing seat, a limit screw threadedly connected to the other end of the first cross brace away from the U-shaped fixing seat, and an adjusting anti-slip rod rotatably connected to the surface of the limit screw.

[0007] According to the above technical solution, the U-shaped fixing seat has a lower threaded groove inside and an upper threaded groove inside.

[0008] According to the above technical solution, an upper arc-shaped plate is welded to the top of the inner end of the outer pipe, and a vertical support is installed at the lower end of the upper arc-shaped plate.

[0009] According to the above technical solution, a left mounting strip is fixedly connected to the front left end of the vertical support, and the structure of the left mounting strip is the same as that of the right mounting strip.

[0010] According to the above technical solution, the side end of the right mounting strip is equipped with a second cross brace via a U-shaped fixing seat.

[0011] According to the above technical solution, an upper clamping plate is fixedly connected to the side end of the upper clamping sleeve, a lower clamping plate is fixedly connected to the side end of the lower clamping sleeve, and a bolt is threaded into the upper clamping plate.

[0012] According to the above technical solution, an outer support base is fixedly connected to the bottom of the lower sleeve, and a base is fixedly installed at the lower end of the outer support base.

[0013] According to the above technical solution, a threaded groove is provided inside the base and on the side end of the outer support seat.

[0014] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: Before installing the outer pipe, the outer pipe can be placed on the surface of the lower jacket, then the upper jacket is fitted, and the position of the upper jacket is positioned using the upper and lower clamping plates. The upper and lower jackets are then fixed together with bolts, clamping the outer pipe inside the upper and lower jackets. Vertical supports are welded inside the outer pipe, which can separate the internal space of the outer pipe, forming left and right chambers. This separates the cables in the left and right spaces, preventing the formation of closed conductors, thereby eliminating the eddy current phenomenon caused by the alternating magnetic field generated around three-phase or single-phase single-core cables, reducing power loss, and eliminating the safety hazard of conductor overheating and cable burnout due to eddy currents. A right mounting strip, installed on the surface of the vertical support, is used to install cable support devices. The inside of the right mounting strip has multiple mounting slots for installing U-shaped fixing seats at different positions and heights. A first cross brace, installed on the side end of the U-shaped fixing seat, supports the cable. An adjustable anti-slip rod, which can be rotated and adjusted, is installed at the top of the first cross brace. The anti-slip rod is secured by a limit screw and a nut. In use, U-shaped fixing seats of different heights can be installed through different mounting holes and lower mounting slots to adjust the height of the first cross brace. When installing first cross braces of different heights, the nut at the limit screw can be removed first, allowing the anti-slip rod to rotate until the end away from the first cross brace is flush with the inside of the outer pipe, before fixing the position of the anti-slip rod. The anti-slip rod prevents the cable from falling off the surface of the first cross brace. Multiple first cross braces and adjustable anti-slip rods divide the chamber at one end into multiple cable support spaces, allowing for support of different numbers and sizes of cables by installing different numbers and heights of first cross braces. The device has multiple adjustable cable support structures inside, which facilitates installation and improves the device's applicability. Attached Figure Description

The upper and lower ends of the outer surface of the outer pipe 1 are conveniently clamped and limited by the upper clamp 2 and the lower clamp 3. A support structure is mounted on the lower end of the lower clamp 3 to support the entire device. A vertical support 7 is welded inside the outer conduit 1. The vertical support 7 can separate the internal space of the outer conduit 1, forming left and right chambers. This separates the cables in the left and right spaces, preventing them from forming closed conductors. This eliminates the eddy current phenomenon caused by the alternating magnetic field generated by the three-phase or single-phase single-core cable, reducing power loss and eliminating the safety hazard of conductor overheating and cable burnout caused by eddy currents. A right mounting strip 8 is installed on the surface of the vertical support 7 for installing cable support devices. The right mounting strip 8 has multiple mounting slots inside, which can be used to install U-shaped fixing seats 12 at different positions and heights. A first cross brace 15 is installed on the side end of the U-shaped fixing seat 12 to support the cable. An adjustable anti-slip rod 19 is installed at the top of the first cross brace 15. The adjustable anti-slip rod 19 is installed by a limit screw 18 and a nut. In use, U-shaped mounting bases 12 of different heights can be installed through the mounting holes 10 and lower mounting grooves 11 at different positions to adjust the height of the first cross brace 15. When installing the first cross brace 15 at different heights, the nut at the limiting screw 18 can be removed first to allow the adjusting anti-slip rod 19 to rotate. After the other end of the adjusting anti-slip rod 19 away from the first cross brace 15 can fit against the inside of the outer pipe 1, the position of the adjusting anti-slip rod 19 can be fixed. The adjusting anti-slip rod 19 can prevent the cable from falling off the surface of the first cross brace 15. Multiple first cross braces 15 and adjusting anti-slip rods 19 can divide the chamber at one end into multiple cable support spaces. When facing cables of different quantities and sizes, different numbers and heights of first cross braces 15 can be installed for support.

[0023] Please see Figure 1-2 The U-shaped fixing seat 12 has a lower threaded groove 13 and an upper threaded groove 14 inside.

[0026] Please see Figure 1-4 A second cross brace 20 is mounted on the side end of the right mounting strip 8 via a U-shaped fixing seat 12. Multiple U-shaped fixing seats 12 are mounted on the surface of the right mounting strip 8, and the adjustable anti-slip rods 19 mounted on the U-shaped fixing seats 12 at different heights have different tilt angles. The adjustable anti-slip rods 19 facilitate quick and easy installation of the bracket by workers.

[0027] Please see Figure 1-3 The upper clamping sleeve 2 has an upper clamping plate 21 fixedly connected to its side end, and the lower clamping sleeve 3 has a lower clamping plate 22 fixedly connected to its side end. The upper clamping plate 21 has a bolt 23 threadedly connected to its interior. Before installing the outer pipe 1, the outer pipe 1 can be placed on the surface of the lower clamping sleeve 3, then the upper clamping sleeve 2 is fitted on, and the upper clamping plate 21 and the lower clamping plate 22 are used to position the upper clamping sleeve 2. Then, the upper clamping sleeve 2 and the lower clamping sleeve 3 are fixed together by the bolt 23, clamping the outer pipe 1 inside the upper clamping sleeve 2 and the lower clamping sleeve 3.
