Abstract
Description
Technical Field
[0001] This utility model relates to the field of underground pipeline technology, specifically to an underground pipeline. Background Technology
[0002] Underground pipelines refer to various pipes and cables built below the surface of a city, including water supply, drainage, gas, heating, electricity, communications, broadcasting and television, industrial pipelines, and their ancillary facilities. These pipelines are an important part of urban infrastructure, often referred to as the city's "lifeline," responsible for the supply, distribution, and transmission of industrial and residential power, ensuring the normal operation of the city.
[0003] A search of patent application number CN202110252156.9 reveals that this invention relates to a self-heating underground pipeline. This invention avoids the problem of reduced flow rate due to material solidification upon cooling, ensuring the effectiveness and efficiency of material transfer within the underground pipeline. However, in practice, this invention does not address the issue that during prolonged use, the pipeline's seals may shift due to soil settlement, changes in ground pressure, root influence, and sealant wear, leading to unstable sealing and an inconvenience in maintaining a stable connection between the seals and the pipeline.
[0004] Further searching patent application number CN200620047038.5 reveals a utility model that discloses an underground splicing pipeline. This pipeline is easy to install as it is not limited by terrain; it is not corroded when used as a sewage pipe; and it is inexpensive. However, in the case of the aforementioned two applications CN202123183570.3 and CN200620047038.5, when burying pipes and cables underground, both ends of the pipe need to be sealed with sealants to ensure waterproofing, moisture-proofing, and corrosion resistance. However, during long-term use, the pipe sealants may indeed shift due to soil settlement, changes in ground pressure, root influence, and sealant wear, leading to unstable sealing and making it difficult to stably connect the sealants to the pipe, resulting in inconvenience in use. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an underground pipeline that solves the problem that, during long-term use, the pipeline's sealing components may shift due to soil settlement, changes in ground pressure, root influence, sealant wear, and other reasons, resulting in unstable sealing and an inconvenience in maintaining a stable connection between the sealing components and the pipeline.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an underground pipeline, including a pipe and a cable, wherein protective mechanisms are provided inside both ends of the pipe, and grooves are provided on the inner wall of the pipe.
[0007] The protective mechanism includes a sealing plate that contacts the inner wall of the pipe. A mounting block is fixedly installed on one side of the sealing plate, and a groove is provided on the side of the mounting block away from the sealing plate. A sliding block is provided inside the groove and is slidably connected to the groove. A moving rod is provided on one side of the sliding block and is fixedly connected to the sliding block. A threaded rod is provided inside the groove. A ring is provided on one side of the sealing plate and is in contact with the sealing plate. A fixing plate is provided on the outer side of the ring, and the surface of the fixing plate away from the ring is inclined.
[0008] Preferably, an annular plate is fixedly installed inside the pipe, and the mounting block penetrates the annular plate and is in contact with the annular plate.
[0009] Preferably, a crossbar is fixedly provided on the outer side of the ring, one end of the crossbar is in contact with the inner wall of the pipe, and a connecting rod is provided inside the groove. The connecting rod is slidably connected to the push plate through one end of the positioning rod, which can ensure that the push plate can only move along the direction of the positioning rod and prevent it from moving with the fixed plate.
[0010] Preferably, the connecting rod is threadedly connected to the threaded rod, and the surface of the threaded rod near the sealing plate is provided with a cross groove. By using a relevant tool, such as a Phillips screwdriver, the screwdriver can be fused with the cross groove, which facilitates the rotation of the threaded rod.
[0011] Preferably, a push plate is provided on the side of the fixed plate near the slide groove, and the push plate is slidably connected to the fixed plate, and a positioning rod is provided on one side of the push plate.
[0012] Preferably, the positioning rod has an L-shaped cross-section, one end of the positioning rod is fixedly connected to the inner wall of the pipe, and the other end of the positioning rod is slidably connected to the push plate. The fixed connection between the positioning rod and the pipe can prevent the positioning rod from moving and improve the stability of the positioning rod.
[0013] Preferably, a connecting spring is provided inside the chute, a hole is provided inside the annular plate, and a hook is fixedly provided at one end of the moving rod.
[0014] Preferably, one end of the hook rod is adapted to the hole, the hook rod is in contact with the mounting block, and the hook rod, which is fixedly connected to the moving rod, moves automatically, allowing the hook rod to move in a straight line, so that one end of the hook rod can gradually merge with the hole.
[0015] Beneficial effects
[0016] This utility model provides an underground pipeline. Compared with the prior art, it has the following advantages:
[0017] 1. This underground pipeline, with a sealing plate installed inside the pipe, allows the mounting block to contact the annular plate and the moving rod to contact the fixed plate, facilitating subsequent operations. The threaded rod allows the push plate to move, causing the moving rod to move and misalign with the mounting block, so that part of the moving rod contacts the annular plate, and the hook rod contacts the annular plate, increasing the stability of the connection between the sealing plate and the pipeline, preventing displacement, and facilitating long-term use.
[0018] 2. The underground pipeline is slidably connected to the push plate through one end of the positioning rod, which ensures that the push plate can only move along the direction of the positioning rod, preventing it from moving along with the fixed plate. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-4 This utility model provides a technical solution: an underground pipeline, including a pipe 1 and a cable 3, with protective mechanisms 2 installed inside both ends of the pipe 1, and grooves 4 installed on the inner wall of the pipe 1.
[0027] The protection mechanism 2 includes a sealing plate 201, which is in contact with the inner wall of the pipe 1. A mounting block 202 is fixedly provided on one side of the sealing plate 201, and a groove 203 is provided on the side of the mounting block 202 away from the sealing plate 201. A sliding block 204 is provided inside the groove 203, and the sliding block 204 is slidably connected to the groove 203. A moving rod 205 is provided on one side of the sliding block 204, and the moving rod 205 is fixedly connected to the sliding block 204. A threaded rod 206 is provided inside the groove 4. A ring 207 is provided on one side of the sealing plate 201, and the ring 207 is in contact with the sealing plate 201. A fixing plate 208 is provided on the outer side of the ring 207, and the surface of the fixing plate 208 away from the ring 207 is inclined.
[0028] A crossbar 210 is fixedly installed on the outer side of the ring 207. One end of the crossbar 210 contacts the inner wall of the pipe 1. A connecting rod 211 is installed inside the groove 4. The connecting rod 211 is threadedly connected to the threaded rod 206. The surface of the threaded rod 206 near the sealing plate 201 is set with a cross groove. The positioning rod 213 has an L-shaped cross section. One end of the positioning rod 213 is fixedly connected to the inner wall of the pipe 1, and the other end of the positioning rod 213 is slidably connected to the push plate 212. A connecting spring is installed inside the slide groove 203. A hole 214 is installed inside the annular plate 209. A hook rod 215 is fixedly installed at one end of the moving rod 205. One end of the hook rod 215 is adapted to the hole 214, and the hook rod 215 contacts the mounting block 202.
[0029] Please see Figures 1-3 and Figure 5 A push plate 212 is provided on the side of the fixed plate 208 near the slide groove 203, and the push plate 212 is slidably connected to the fixed plate 208. A positioning rod 213 is provided on one side of the push plate 212. An annular plate 209 is fixedly provided inside the pipe 1. The mounting block 202 passes through the annular plate 209 and is in contact with the annular plate 209.
[0030] During operation, when merging pipe 1 and cable 3, the sealing plate 201 and mounting block 202 in the protection mechanism 2 are installed inside pipe 1, so that the mounting block 202 and moving rod 205 gradually penetrate the annular plate 209, and the mounting block 202 merges with the annular plate 209, and the annular plate 209 contacts the sealing plate 201. The moving rod 205 is positioned on one side of the push plate 212, so that the moving rod 205 contacts the push plate 212, facilitating subsequent operations. Then, using relevant tools, such as a Phillips screwdriver, the screwdriver is merged with the Phillips head groove, which facilitates the rotation of the threaded rod 206. Since the threaded rod 206 is threadedly connected to the connecting rod 211, the rotation of the threaded rod 206 causes the connecting rod 211 to move, so that the connecting rod 211 moves in the groove 4. At the same time, the crossbar 210, which is fixedly connected to the connecting rod 211, also moves. Because the crossbar 210 is fixedly connected to the ring 207, the ring 207 and the fixing plate 208 move simultaneously. During the movement of the fixed plate 208, because one side surface of the fixed plate 208 is inclined, the movement of the fixed plate 208 causes the push plate 212 to move. At this time, the moving rod 205 comes into contact with the push plate 212. The movement of the push plate 212 causes the moving rod 205 to move, which in turn causes the sliding block 204 to move. The sliding block 204 moves in the slide groove 203, causing the moving rod 205 to be misaligned with the mounting block 202. The moving rod 205 moves to one side of the annular plate 209, so that the part of the moving rod 205 comes into contact with the annular plate 209. The hook rod 215, which is fixedly connected to the moving rod 205, moves automatically, allowing the hook rod 215 to move in a straight line. This allows one end of the hook rod 215 to gradually merge with the hole 214, preventing the moving rod 205, mounting block 202 and sealing plate 201 from moving. This increases the stability of the connection between the sealing plate 201 and the pipe 1, prevents displacement, and facilitates long-term use.
[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
