Description

Technical Field

[0001] The utility model relates to the technical field of underground communication cables, in particular to a directly buried pipeline for underground communication cables. Background Art

[0002] An underground communication cable refers to a cable laid underground, mainly used for transmitting telephone calls, telegrams, fax documents, television and radio programs, data and other electrical signals. When laying an underground communication cable, it is necessary to first lay a protective pipeline, which can effectively protect the cable from direct damage by the external environment and is also convenient for subsequent maintenance and repair.

[0003] The Chinese patent discloses a cable pipeline (authorization publication number CN212435316U). This patented technology sets an inner hole and an outer hole between the inner and outer walls of the pipe body to drain the liquid that penetrates into the pipe body by the cooperation of the inner hole and the outer hole, thereby effectively preventing the problem of cable damage caused by liquid penetration into the pipe.

[0004] In view of the above and related existing technologies, the inventor believes that there are often the following defects in the existing directly buried pipeline system for underground communication cables. The system is mainly constructed by directly splicing straight pipe sections. When encountering terrain changes or layout requirements for bending, it is necessary to cut the straight pipes and supplement them with special connectors to meet the bending requirements. However, due to complex on-site conditions, measurement errors or insufficient design estimates, it is difficult to accurately match the sizes of the cut pipes, which in turn leads to problems such as difficult installation, poor sealing and even rework, seriously restricting the operation efficiency of the construction unit and the project progress. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is that in the prior art, when the pipeline needs to be bent, due to complex on-site conditions, measurement errors or insufficient design estimates, it is difficult to accurately match the sizes of the cut pipes, which in turn leads to problems such as difficult installation, poor sealing and even rework. Therefore, we propose a directly buried pipeline for underground communication cables.

[0006] In order to achieve the above purpose, the present application adopts the following technical scheme: A directly buried pipeline for underground communication cables includes a first pipeline. An arc-shaped block is installed on one side of the first pipeline. A second pipeline is rotatably connected inside the arc-shaped block. T-shaped grooves are opened at the top and bottom of the arc-shaped block. Two first T-shaped blocks are slidably connected inside the T-shaped grooves. Symmetric grooves are opened on one side of the first T-shaped blocks. Second T-shaped blocks are fixed at the top and bottom of the first pipeline.

[0007] Preferably, chutes are opened at the top and bottom of the first pipeline. A cylinder is fixed on one side inside the chutes. A baffle is slidably connected to the surface of the cylinder.

[0008] Preferably, one side of the baffle is fixedly connected with a thrust spring, and the other end of the thrust spring is fixedly connected with one side inside the chute.

[0009] Preferably, limiting grooves are formed on both sides inside the chute, limiting blocks are fixed on both sides of the baffle, and the surface of the limiting block is slidably connected with the inside of the limiting groove.

[0010] Preferably, a return spring is fixed inside the first T-shaped block.

[0011] Preferably, a sealing gasket is installed between the first pipe and the inner side of the arc-shaped block.

[0012] Preferably, a fillet is formed on one side of the second pipe.

[0013] The technical effects and advantages of the present utility model:

[0014] In the present utility model, the user inserts the cable into the inside of the first pipe, and after insertion, moves it along the direction towards the second pipe until it is removed from the inside of the second pipe. Then, the arc-shaped block is sleeved on the surface of the second pipe, which is suitable for multi-angle adjustment. Then, by moving the two first T-shaped blocks towards the inner side of the first T-shaped block, the surface of the second T-shaped block is inserted into the inside of the symmetric groove to form a fixation, so that the first pipe and the arc-shaped block are fixed to complete the work of splicing the pipes, improving the efficiency of pipe splicing.

[0020] Now, the present utility model will be further described in detail with reference to the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0021] Referring to Figures 1 - 4 as shown in the figure, the present utility model provides a technical solution: an underground communication cable direct burial pipeline, which includes a first pipeline 1. An arc-shaped block 3 is installed on one side of the first pipeline 1. A second pipeline 2 is rotatably connected inside the arc-shaped block 3. T-shaped grooves 6 are opened at both the top and bottom of the arc-shaped block 3. Two first T-shaped blocks 7 are slidably connected inside the T-shaped grooves 6. Symmetric grooves 15 are opened on one side of the first T-shaped blocks 7. Second T-shaped blocks 8 are fixed at both the top and bottom of the first pipeline 1. The user inserts the cable into the first pipeline 1, and after insertion, moves it along the direction towards the second pipeline 2 until it is removed from the second pipeline 2. Then, the arc-shaped block 3 is sleeved on the surface of the second pipeline 2, which is suitable for multi-angle adjustment. Then, by moving the two first T-shaped blocks 7 towards the inner side of the first T-shaped blocks 7, the surface of the second T-shaped block 8 is inserted into the symmetric grooves 15 to form a fixation, so that the first pipeline 1 and the arc-shaped block 3 are fixed to complete the pipeline splicing work, improving the efficiency of pipeline splicing.

[0022] Referring to Figure 3 as shown in the figure, in this implementation: chutes 9 are opened at both the top and bottom of the first pipeline 1. A cylinder 10 is fixed on one side inside the chutes 9. A baffle 11 is slidably connected to the surface of the cylinder 10. When the surface of the second T-shaped block 8 is fixed with the symmetric grooves 15, by pushing the baffle 11 towards one side of the arc-shaped block 3, the inside of the baffle 11 fixes the surface of the first T-shaped block 7, so that the first T-shaped block 7 will not move to both sides due to shaking, and the surface of the second T-shaped block 8 is separated from the symmetric grooves 15, losing the fixation effect.

[0023] Referring to Figure 3 as shown in the figure, in this implementation: a thrust spring 12 is fixedly connected to one side of the baffle 11, and the other end of the thrust spring 12 is fixedly connected to one side inside the chutes 9. When the user pushes to limit the movement of the first T-shaped block 7 by the baffle 11, due to the thrust of the thrust spring 12, the baffle 11 continuously has a thrust towards the first T-shaped block 7, avoiding the baffle 11 releasing the limit on the first T-shaped block 7 due to shaking, which affects the fixation of the first pipeline 1 and the arc-shaped block 3.

[0024] Referring to Figure 3 as shown in the figure, in this implementation: limiting grooves 13 are opened on both sides inside the chutes 9. Limiting blocks 14 are fixed on both sides of the baffle 11. The surface of the limiting blocks 14 is slidably connected to the inside of the limiting grooves 13. When the user pushes to limit the movement of the first T-shaped block 7 by the baffle 11, due to the limitation of the limiting grooves 13 on the limiting blocks 14, the baffle 11 can maintain the center when moving, avoiding the phenomenon of deviation and getting stuck when the baffle 11 moves towards the first T-shaped block 7.

[0025] Referring to Figure 3As shown in the figure, in this embodiment: A return spring 16 is fixed inside the first T-shaped block 7. When the user needs to release the fixation between the first pipe 1 and the arc-shaped block 3, the baffle 11 is released from limiting the first T-shaped block 7. The thrust of the return spring 16 reduces the pulling force of the user on the first T-shaped block 7, so that the first T-shaped block 7 automatically releases the fixation with the second T-shaped block 8.

[0026] Refer to Figure 1 As shown in the figure, in this embodiment: A gasket 4 is installed inside the first pipe 1 and the arc-shaped block 3. By installing the gasket 4 inside the first pipe 1 and the arc-shaped block 3, the sealing performance inside the pipe can be increased, and it can be avoided that groundwater seeps into the pipe and accelerates the aging of the cable.

[0027] Refer to Figure 2 As shown in the figure, in this embodiment: A rounded corner 5 is provided on one side of the second pipe 2. By providing the rounded corner 5 on one side of the second pipe 2, it can be avoided that the cable is damaged due to friction when the angle of the second pipe 2 is adjusted and rotated.

[0028] Working principle: The user inserts the cable into the inside of the first pipe 1, and after insertion, moves it along the direction towards the second pipe 2 until it is removed from the inside of the second pipe 2. Then, the arc-shaped block 3 is sleeved on the surface of the second pipe 2. Then, by moving two first T-shaped blocks 7 towards the inside of the first T-shaped block 7, the surface of the second T-shaped block 8 is inserted into the inside of the symmetric groove 15 to form a fixation, so that the first pipe 1 and the arc-shaped block 3 are fixed to complete the splicing of the pipe. When the surface of the second T-shaped block 8 and the inside of the symmetric groove 15 are fixed, by pushing the baffle 11 to move towards one side of the arc-shaped block 3, the inside of the baffle 11 fixes the surface of the first T-shaped block 7, so that the first T-shaped block 7 will not move to both sides due to shaking. When the user pushes to limit the movement of the first T-shaped block 7 by the baffle 11, the thrust of the thrust spring 12 makes the baffle 11 continuously have a thrust towards the first T-shaped block 7, avoiding that the baffle 11 releases the limit on the first T-shaped block 7 due to shaking. When the user pushes to limit the movement of the first T-shaped block 7 by the baffle 11, through the limitation of the limiting block 14 by the limiting groove 13, the baffle 11 can maintain the center when moving, avoiding the phenomenon of deviation and getting stuck when the baffle 11 moves towards the first T-shaped block 7. When the user needs to release the fixation between the first pipe 1 and the arc-shaped block 3, the baffle 11 is released from limiting the first T-shaped block 7. The thrust of the return spring 16 reduces the pulling force of the user on the first T-shaped block 7. By installing the gasket 4 inside the first pipe 1 and the arc-shaped block 3, the sealing performance inside the pipe can be increased. By providing the rounded corner 5 on one side of the second pipe 2, it can be avoided that the cable is damaged due to friction when the angle of the second pipe 2 is adjusted and rotated.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
