Description

Technical Field

[0001] The utility model relates to the technical field of underground pipelines, in particular to an anti-settling telescopic structure for underground pipelines. Background Art

[0002] Underground pipelines are pipes buried underground for the transportation of liquids, gases or other substances. Underground pipelines are an indispensable part of modern urban infrastructure. They provide important support for urban water supply, drainage, energy transportation, etc., and also play an important role in urban development and environmental protection.

[0003] When the underground pipeline is used after being buried underground, it may sink or deform due to foundation settlement or other reasons. Therefore, when the underground pipeline is buried, expansion parts will be installed at the pipeline connection to change the overall shape of the pipeline when the pipeline sinks and deforms;

[0004] However, in the process of connecting the above-mentioned expansion joints to the pipeline to prevent subsidence, it was found that the connection between the pipeline and the expansion joint was not tight enough. When the buried pipeline subsided after long-term use and when the pipeline was deformed due to heat or cooling, the pipeline as a whole would be deformed, and the connection between the pipeline and the expansion joint would easily become loose and misaligned, affecting the normal use of the buried pipeline.

[0005] In summary, there is a need for an anti-settling telescopic structure for buried pipelines that can be stably connected. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1: To solve the technical problems in the background technology, the following underground pipeline anti-settling telescopic structure is provided:

[0025] Combination Figure 1-Figure 4 As shown, the utility model provides an anti-sinking telescopic structure for buried pipelines, including a connecting tube 1, which is distributed in a mirror image. A connecting assembly 4 connected to a pipeline body 5 is provided on the inner side of the connecting tube 1, and a plurality of movable tubes 2 and telescopic members 3 are provided between the connecting tubes 1; the connecting assembly 4 includes a connecting ring 41, an annular mounting plate 42, a reinforcing rod 43 and a reinforcing screw ring 44. The connecting ring 41 is provided on the inner side of the connecting tube 1, and an annular mounting plate 42 is provided on the side. A reinforcing rod 43 is provided on the outer side of the annular mounting plate 42, and a reinforcing screw ring 44 is provided on the outer side of the reinforcing rod 43. The connecting tube 1 and the annular mounting plate 42 are connected to each other. A connection area is formed between the pipe body 5, the connection area is snap-connected with the pipe body 5, the annular mounting plate 42 and the connecting tube 1 are both slidably connected with the pipe body 5, the reinforcing spiral ring 44 is threadedly connected with the reinforcing rod 43, and an anti-slip component is provided on the outside of the connecting tube 1. The annular mounting plate 42 provided in the connecting component 4 can cooperate with the connecting tube 1 to squeeze and fix the pipe body 5 under the threaded connection of the reinforcing spiral ring 44 and the reinforcing rod 43. In this way, the connecting tube 1 and the annular mounting plate 42 can be firmly combined and connected with the pipe body 5, which is conducive to the stable and firm connection combination of the telescopic structure and the pipe body;

[0026] In this embodiment, a plurality of reinforcing rods 43 and reinforcing spiral rings 44 are arranged in a ring outside the annular mounting plate 42, so that the reinforcing rods 43 and reinforcing spiral rings 44 can assist the annular mounting plate 42 in squeezing the pipe body 5 at multiple positions on the pipe body 5;

[0027] In this embodiment, there are multiple groups of anti-skid components distributed in a ring array outside the connecting tube 1. The anti-skid components include a locking seat 46 and a locking screw 45. The locking seat 46 is fixedly arranged on the outside of the connecting tube 1. A locking screw 45 is arranged in the middle of the locking seat 46. The locking screw 45 is threadedly connected to the locking seat 46. The bottom end of the locking screw 45 contacts the outside of the pipeline body 5. The locking screw 45 is arranged in the protective component. Under the action of the threaded connection with the locking seat 46, the pipeline body 5 can be squeezed, thereby making the pipeline body 5 and the connecting tube 1 more firmly and stably connected, which is conducive to avoiding the situation where the pipeline body 5 is separated from the telescopic structure when the pipeline settles;

[0028] The implementation principle of the first embodiment is that when the telescopic structure is used, the connecting component 4 on the inner side of the connecting tube 1 is first connected to the pipe body 5, so that the annular mounting plate 42 is inserted into the inner side of the pipe body 5, and then the reinforcing screw ring 44 is rotated to pull the annular mounting plate 42. At this time, the annular mounting plate 42 will cooperate with the connecting tube 1 to squeeze the pipe body 5. At the same time, the locking screw 45 is rotated, and the locking screw 45 will move downward on the inner side of the locking seat 46 to squeeze and fix the pipe body 5, thereby enabling the pipe body 5 to be firmly and stably combined and connected with the telescopic structure.

[0029] Embodiment 2: Figure 1-Figure 2 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0030] In order to enable the telescopic structure to achieve the function of anti-settling, this embodiment provides the following design:

[0031] There are multiple groups of movable cylinders 2 and telescopic members 3 between the connecting cylinder 1. The multiple groups of telescopic members 3 and the movable cylinder 2 are distributed in sequence. The multiple groups of movable cylinders 2 and telescopic members 3 can cooperate with each other to deform when the pipeline body 5 is used to settle, so as to avoid deformation and breakage of the pipeline when the pipeline is settled as a whole.

[0032] In this embodiment, the telescopic member 3 includes a telescopic annular sleeve 31 and a mounting ring 32. The telescopic annular sleeve 31 is an elastic structure. The mounting rings 32 are provided at both ends of the telescopic annular sleeve 31. The mounting rings 32 are fixedly connected to the movable cylinder 2. The telescopic annular sleeve 31 with an elastic structure can be telescopically deformed according to the settlement posture when the pipeline is settled as a whole.

[0033] In this embodiment, mounting blocks 21 are provided on the inner side of the movable cylinder 2 and the inner side of the connecting cylinder 1. The mounting blocks 21 are arranged in a ring in multiple groups on the inner side of the movable cylinder 2 and the inner side of the connecting cylinder 1. A slide groove is provided in the middle of the mounting block 21. A shaping strip 22 is provided inside the slide groove. The shaping strip 22 slides in engagement with the slide groove. The shaping strip 22 has an elastic structure. The shaping strip 22 of the elastic structure can slide and deform in the slide groove provided in the middle of the mounting block 21 after the telescopic structure is deformed, so as to achieve the purpose of supporting the telescopic mechanism.

[0034] The implementation principle of the second embodiment is: when the pipeline body 5 is installed with the telescopic structure and buried underground and sinks, the multiple groups of movable cylinders 2 and the telescopic parts 3 arranged between the connecting cylinders 1 can cooperate with the deformation, change the shape between the pipeline body 5, adapt to the deformation shape of the buried pipeline, and avoid deformation and rupture of the buried pipeline due to settlement.
