Description

Technical Field

[0001] This utility model relates to the field of rectangular corrugated pipe structure technology, specifically a rectangular corrugated pipe structure with displacement monitoring capability. Background Technology

[0002] The main function of the displacement-monitoring rectangular corrugated pipe structure is to compensate for displacement, absorb vibration, and isolate noise in pipeline systems, while adapting to the installation requirements of rectangular cross-section pipes. Through the elastic deformation of its own corrugated structure, it can effectively absorb the axial, lateral, or angular displacement of the pipeline caused by temperature changes (such as thermal expansion and contraction), preventing the pipeline from cracking or being damaged due to stress concentration. Its corrugated structure can also reduce the noise generated by fluid flow or equipment operation, thus playing a noise reduction role.

[0003] The existing patent publication number CN217211232U discloses a corrugated pipe structure, which includes a second mounting end and a first mounting end. The second mounting end on one set of corrugated pipe bodies can be brought into close contact with the first mounting end on an adjacent set of corrugated pipe bodies, and the first insertion ring and the second insertion ring are respectively inserted into the interior of the first embedding ring groove and the second embedding ring groove, so that the second mounting end on the two adjacent sets of corrugated pipe bodies can be inserted into the first mounting end. The second mounting end and the first mounting end can be used to make the corrugated pipe body have mounting ends. At the same time, the first embedding ring groove and the second embedding ring groove, together with the first insertion ring and the second insertion ring, can be used to position the corrugated pipe body during assembly.

[0004] When the above-mentioned device is installed and used, it cannot limit the maximum deformation of the corrugated pipe. The displacement caused by thermal expansion and contraction or vibration of the pipe will exceed its bearing capacity, resulting in the corrugated pipe breaking and affecting its use. In order to address the above problems, a rectangular corrugated pipe structure with displacement monitoring is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a rectangular corrugated pipe structure with displacement monitoring capability to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rectangular corrugated pipe structure with displacement monitoring includes a corrugated pipe body and a monitor disposed on one side of the corrugated pipe body. The top and bottom of the corrugated pipe body are fixedly connected to mounting plates. Several sets of limiting rods are disposed between the two sets of mounting plates. A positioning component for fixing the rotation of the limiting rods is disposed on one set of mounting plates.

[0008] The positioning assembly includes a limiting plate and a rotating block. The limiting plate is fixedly connected to the top of the mounting plate, and the rotating block is fixedly connected to the bottom of the limiting rod. A through hole is provided on one side of the rotating block, and a fixing bolt is sleeved in the through hole. A threaded hole for threaded connection with the fixing bolt is provided on one side of the limiting plate, and a fixing nut is fixedly connected in the through hole. The inner wall of the fixing nut is threadedly connected to the outer surface of the fixing bolt. A limiting component for guiding the movement of the fixing bolt is provided on one side of the limiting plate.

[0009] The limiting rod is equipped with a fixing component for limiting the position of another set of mounting plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model, by setting up a corrugated pipe body, mounting plate, limiting rod, positioning component and fixing component, guides the rotation of the limiting rod and limits the axial displacement of the two sets of pipes. The fixing component limits and fixes the distance between the two sets of mounting plates, thereby limiting the lateral displacement between the two sets of pipes. It can limit the maximum deformation of the corrugated pipe body and avoid the displacement caused by thermal expansion and contraction or vibration of the pipes from exceeding the bearing capacity of the corrugated pipe body and causing breakage.

Detailed Implementation

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] 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.

[0025] Please see Figures 1-4In this embodiment, a rectangular corrugated pipe structure with displacement monitoring includes a corrugated pipe body 11 and a monitor 12 disposed on one side of the corrugated pipe body 11. The monitor 12 is used to capture the axial and lateral displacement and deformation state of the corrugated pipe body 11 caused by pipe thermal expansion and contraction, vibration or foundation settlement in real time. It acquires displacement data through built-in sensing elements and can transmit the information to a terminal platform to realize real-time monitoring and abnormal early warning of displacement. This is prior art and will not be described in detail in this application. The top and bottom of the corrugated pipe body 11 are fixedly connected to mounting plates 13. Several sets of limiting rods 16 are disposed between the two sets of mounting plates 13. A positioning component for fixing the rotation of the limiting rods 16 is disposed on one set of mounting plates 13.

[0026] The positioning assembly includes a limiting plate 14 and a rotating block 15. The limiting plate 14 is fixedly connected to the top of the mounting plate 13, and the rotating block 15 is fixedly connected to the bottom of the limiting rod 16. A through hole 20 is provided on one side of the rotating block 15, and a fixing bolt 17 is sleeved in the through hole 20. A threaded hole 21 for threaded connection with the fixing bolt 17 is provided on one side of the limiting plate 14. A fixing nut 18 is fixedly connected in the through hole 20, and the inner wall of the fixing nut 18 is threadedly connected to the outer surface of the fixing bolt 17. A setting for fixing the fixing bolt 17 is provided on one side of the limiting plate 14. The limiting component guides the movement of the fixed bolt 17, causing the fixed bolt 17 to rotate outward, disengaging it from the threaded connection between the fixed bolt 17 and the fixed nut 18 and the threaded hole 21. The limiting component guides the movement of the fixed bolt 17, releasing the restriction on the limiting rod 16, allowing the limiting rod 16 to rotate. When fixed, the fixed bolt 17 rotates inward, causing the fixed bolt 17 to be threadedly connected to the fixed nut 18 and the threaded hole 21, thus fixing and limiting the limiting rod 16. This can limit the maximum deformation of the bellows body 11, preventing the displacement caused by thermal expansion and contraction or vibration of the pipeline from exceeding the tolerance range of the bellows body 11 and causing breakage.

[0027] The limiting rod 16 is provided with a fixing component for limiting the other set of mounting plates 13.

[0028] The limiting component includes a positioning rod 22 and a positioning block 19. Two sets of positioning rods 22 are fixedly connected to one side of the limiting plate 14. The positioning block 19 is rotatably mounted on the fixing bolt 17. A positioning hole 23 is provided on one side of the positioning block 19 for sliding connection with the positioning rod 22. A screw block 26 is fixedly connected to one end of the fixing bolt 17 to prevent the fixing bolt 17 from shifting or shaking during the adjustment process, ensuring that it can be accurately aligned with the threaded hole 21 and avoiding installation or fixing failure due to misalignment.

[0029] The fixing assembly includes a limiting nut 28, which is threadedly connected to the limiting rod 16. Another set of mounting plates 13 has an insertion hole for the limiting rod 16 to pass through. The bottom of the other set of mounting plates 13 is provided with a positioning nut 29, which is threadedly connected to the limiting rod 16. The limiting nut 28 is located on top of the other set of mounting plates 13. By adjusting the limiting nut 28 and the positioning nut 29, the relative position of the two sets of mounting plates 13 can be fixed, further restricting the lateral displacement of the bellows body 11.

[0030] A limiting ring 24 is fixedly connected to the fixing bolt 17. The inner wall of the positioning block 19 is provided with a limiting groove 25 for rotating connection with the limiting ring 24. By setting the limiting ring 24 and the limiting groove 25, the axial relative displacement between the positioning block 19 and the fixing bolt 17 can be limited, ensuring that the positioning block 19 moves synchronously with the fixing bolt 17.

[0031] A baffle is fixedly connected to the fixing bolt 17. The baffle is slidably connected in the through hole 20. By setting the baffle, the fixing bolt 17 can be prevented from dislodging from the through hole 20.

[0032] An inner sleeve 27 is provided inside the corrugated pipe body 11. The outer surface of one end of the inner sleeve 27 is fixedly connected to the inner wall of the corrugated pipe body 11. By providing the inner sleeve 27, the impact resistance and sealing performance of the corrugated pipe body 11 can be enhanced, and the medium can be prevented from directly scouring the inner wall of the corrugated pipe, thus avoiding wear.

[0033] The working principle of this utility model is as follows: In use, firstly, bolts are used to connect the two sets of mounting plates 13 to the two sets of pipes respectively. According to the adjustment of the pipes, the limiting rod 16 is adjusted. Rotating the screw block 26 drives the fixing bolt 17 to rotate outward, so that the fixing bolt 17 is disengaged from the threaded connection between the fixing nut 18 and the threaded hole 21. At the same time, the fixing bolt 17 drives the limiting ring 24 to rotate in the limiting groove 25, so that the positioning rod 22 slides in the positioning hole 23, releasing the restriction on the limiting rod 16, allowing the limiting rod 16 to rotate. When fixing, rotating the screw block 26 drives the fixing bolt 17 to rotate inward, so that the fixing bolt 17 is threadedly connected to the fixing nut 18 and the threaded hole 21. At the same time, the positioning rod 22 slides in the positioning hole 23, fixing and limiting the limiting rod 16. Then, the limiting nut 28 and the positioning nut 29 are rotated and adjusted, which can limit the maximum deformation of the corrugated pipe body 11 and prevent the displacement caused by the thermal expansion and contraction or vibration of the pipe from exceeding the bearing capacity of the corrugated pipe body 11 and causing breakage.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
