Description

Technical Field

[0001] This utility model belongs to the technical field of fluid transportation pipeline compensation, specifically relating to a retractable water supply pipeline compensator. Background Technology

[0002] In the operation of water supply pipeline systems, expandable water supply pipeline compensators play a crucial role. They are mainly used to absorb axial, lateral, or angular displacements caused by factors such as thermal expansion and contraction, mechanical vibration, and foundation settlement, thus protecting the safe and stable operation of the pipeline system.

[0003] While traditional expandable water supply pipeline compensators can achieve basic displacement compensation, they have some limitations in practical applications. One key issue is the lack of effective means to monitor the compensator's deformation in real time. Because the degree of expansion and contraction of the expandable corrugated sleeve cannot be directly and accurately determined, operators struggle to promptly assess whether the compensator is functioning properly. During long-term pipeline operation, various complex factors can lead to excessive deformation of the expandable corrugated sleeve. If this excessive deformation is not detected and addressed promptly, it can accumulate, eventually causing compensator failure and resulting in serious problems such as pipeline rupture and leakage. This not only wastes water resources but may also damage the surrounding environment and infrastructure. Utility Model Content

[0004] The purpose of this utility model is to provide a retractable water supply pipeline compensator to solve the problem mentioned in the background art that the traditional retractable water supply pipeline compensator can achieve basic displacement compensation, but has limitations. The key problem is the lack of an effective means to monitor deformation in real time, making it difficult for staff to judge its working status. During long-term operation, the retractable corrugated pipe sleeve may be excessively deformed. If not dealt with in time, it will cause the compensator to fail, leading to serious consequences such as pipeline rupture and leakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a retractable water supply pipeline compensator, comprising a retractable corrugated pipe sleeve and a connecting sleeve A disposed at the right end of the retractable corrugated pipe sleeve, a connecting sleeve B disposed at the left end of the retractable corrugated pipe sleeve, a bracket mounting flange A disposed on the outer side of the right end of the connecting sleeve A, and a bracket mounting flange B disposed on the outer side of the left end of the connecting sleeve B. Multiple tie rod fixing blocks A are equidistantly welded to the circular outer wall of the bracket mounting flange A, and tie rod fixing blocks B are equidistantly welded to the circular outer wall of the bracket mounting flange B. The multiple tie rod fixing blocks A and B are symmetrically arranged. Tie rod through holes are provided inside both tie rod fixing blocks A and B. Metal connecting tie rods are connected to the tie rod through holes inside the tie rod fixing blocks A and B. The multiple metal connecting tie rods are equidistantly arranged around the circular outer side of the retractable corrugated pipe sleeve, connecting sleeve A, and connecting sleeve B. A visual deformation monitoring device is provided on each of the multiple metal connecting tie rods.

[0006] Preferably, the visual deformation monitoring device on the upper exterior of the retractable corrugated pipe sleeve includes a strip-shaped monitoring rod, a monitoring connecting strip, a connecting rod, a movable hole, and a metal fixing sleeve. The metal fixing sleeve is sleeved and fixed to the outside of the metal connecting rod. Connecting rods are welded to both sides of the center of the bottom end of the metal fixing sleeve. Both connecting rods extend vertically downwards. The bottom ends of the two connecting rods are connected to the monitoring connecting strip. A movable hole is provided inside the center of the monitoring connecting strip. The strip-shaped monitoring rod is inserted into the movable hole. The strip-shaped monitoring rod can move up and down in the movable hole, but it cannot rotate in the movable hole.

[0007] Preferably, the visual deformation monitoring device further includes a contact strip and a compression spring. The bottom end of the strip-shaped monitoring rod is fixed with a contact strip. The contact strip and the monitoring connecting strip are parallel to each other. A compression spring is connected between the left and right sides of the center of the contact strip and the monitoring connecting strip.

[0008] Preferably, the bottom end of the contact strip can be attached to the outer wall of the outwardly protruding top of the retractable corrugated sleeve, and both compression springs are in a semi-compressed state. The left and right edges of the bottom of the contact strip are both treated with arc surfaces.

[0009] Preferably, the visual deformation monitoring device further includes a baffle and a deformation monitoring scale line. The baffle is fixed at the top of the strip-shaped monitoring rod. When the bottom end of the contact strip is attached to the outer wall of the protruding top of the telescopic corrugated sleeve, the bottom end of the baffle is attached to the outer wall of the top of the monitoring connecting strip, and the baffle is blocked at the top of the monitoring connecting strip. The outer wall of the front end of the strip-shaped monitoring rod is provided with a deformation monitoring scale line, and the deformation monitoring scale line is measured in millimeters.

[0010] Preferably, both ends of the metal connecting rod are threaded, and two fixing nuts A are threaded onto the right end of the metal connecting rod. The two fixing nuts A are located at the left and right ends of the rod fixing block A, respectively.

[0011] Preferably, the left end of the metal connecting rod is externally threaded with two fixing nuts B, which are located at the left and right ends of the rod fixing block B, respectively.

[0012] Preferably, the retractable corrugated sleeve, connecting sleeve A and connecting sleeve B are all made of stainless steel. The retractable corrugated sleeve can absorb the axial, lateral or angular displacement of the water supply pipeline caused by thermal expansion and contraction, mechanical vibration and foundation settlement through its own elastic expansion and contraction deformation.

[0013] Compared with the prior art, this utility model provides a retractable water supply pipeline compensator, which has the following beneficial effects:

[0014] This invention adds a novel visual deformation monitoring device to each metal connecting rod of the expandable water supply pipeline compensator. After multiple metal connecting rods surround the expandable corrugated sleeve, multiple visual deformation monitoring devices are attached to the outer wall of the outwardly protruding part of the expandable corrugated sleeve via contact strips. When the expandable corrugated sleeve expands and contracts elastically, it absorbs the axial, lateral, or angular displacement of the water supply pipeline caused by thermal expansion and contraction, mechanical vibration, and foundation settlement. When the expandable corrugated sleeve deforms outward, the visual deformation monitoring device can directly display the upward deformation distance of the expandable corrugated sleeve. This visual design allows workers to easily monitor the deformation. Without the need for complex testing equipment, the deformation of the expandable corrugated pipe sleeve can be directly observed during routine inspections. By reading the deformation monitoring scale on the strip monitoring rod, the deformation can be accurately determined in millimeters. This clear measurement provides intuitive and accurate data for judging the working status of the compensator. Once the deformation is found to be close to or beyond the normal range, staff can take timely measures, such as checking for abnormal stress concentration in the pipeline system, assessing whether pipeline adjustments or compensator maintenance and replacement are necessary. This effectively avoids serious problems such as pipeline rupture and leakage caused by excessive deformation of the compensator, greatly improving the safety and reliability of the water supply pipeline system.

Detailed Implementation

[0020] 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.

[0021] This utility model provides, for example Figure 1-4The expandable water supply pipe compensator shown includes an expandable corrugated pipe sleeve 5 and a connecting sleeve A1 located at the right end of the expandable corrugated pipe sleeve 5. A connecting sleeve B7 is located at the left end of the expandable corrugated pipe sleeve 5. A bracket mounting flange A2 is located on the outer side of the right end of the connecting sleeve A1. A bracket mounting flange B8 is located on the outer side of the left end of the connecting sleeve B7. Multiple tie rod fixing blocks A3 are welded at equal intervals to the circular outer wall of the bracket mounting flange A2. Tie rod fixing blocks B6 are welded at equal intervals to the circular outer wall of the bracket mounting flange B8. A3 and multiple tie rod fixing blocks B6 are symmetrically arranged. This symmetrical structural design ensures that the compensator is subjected to uniform force in all directions, avoiding structural deformation or damage caused by uneven force. Both tie rod fixing blocks A3 and B6 have tie rod through holes inside, through which metal connecting tie rods 4 are connected. Multiple metal connecting tie rods 4 are equidistantly arranged around the circular exterior of the retractable corrugated sleeve 5 and the connecting sleeves A1 and B7. Both ends of the tie rod 4 are threaded. Two fixing nuts A11 are threaded onto the right end of the metal connecting tie rod 4, located at the left and right ends of the tie rod fixing block A3, respectively. Two fixing nuts B9 are threaded onto the left end of the metal connecting tie rod 4, located at the left and right ends of the tie rod fixing block B6, respectively. Both tie rod fixing blocks A3 and B6 have through holes through which the metal connecting tie rod 4 passes, connecting the connecting sleeve A1, the telescopic corrugated sleeve 5, and the connecting sleeve B7 into a single unit. The threaded design at both ends of the metal connecting tie rod 4, with two fixing nuts A11 threaded onto the right end (located at the left and right ends of the tie rod fixing block A3) and two fixing nuts B9 threaded onto the left end (located at the left and right ends of the tie rod fixing block B6), ensures a secure connection between components and prevents loosening during pipeline operation.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, the expandable corrugated sleeve 5, connecting sleeve A1, and connecting sleeve B7 are all made of stainless steel. The expandable corrugated sleeve 5 can absorb the axial, lateral, or angular displacement of the water supply pipeline caused by thermal expansion and contraction, mechanical vibration, and foundation settlement through its own elastic expansion and contraction deformation. During the operation of the water supply pipeline system, the pipeline will experience axial, lateral, or angular displacement due to thermal expansion and contraction, mechanical vibration, and foundation settlement. When these displacements occur, the expandable corrugated sleeve 5 will absorb these displacements through its own elastic expansion and contraction deformation according to the direction and magnitude of the displacement. For example, when the pipeline undergoes axial elongation due to thermal expansion, the expandable corrugated sleeve 5 will correspondingly stretch axially, thereby relieving the internal stress of the pipeline. When the pipeline experiences lateral displacement due to foundation settlement, the expandable corrugated sleeve 5 can adapt to this change through lateral deformation, ensuring the continuity and sealing of the pipeline system and avoiding problems such as pipeline rupture and leakage due to excessive displacement.

[0023] like Figure 1 and Figure 4 As shown, multiple metal connecting rods 4 are equipped with visual deformation monitoring devices 10. The visual deformation monitoring device 10 on the upper exterior of the telescopic corrugated sleeve 5 includes a strip-shaped monitoring rod 14, a monitoring connecting strip 15, a connecting rod 16, a movable hole 17, and a metal fixing sleeve 18. The metal fixing sleeve 18 is sleeved and fixed to the outside of the metal connecting rod 4. This sleeved connection method ensures that the monitoring device is tightly connected to the overall structure of the compensator and does not affect the normal function of the metal connecting rod 4 in the compensator. Connecting rods 16 are welded to the left and right sides of the center of the bottom end of the metal fixing sleeve 18. Both connecting rods 16 extend vertically downwards, and the bottom ends of the two connecting rods 16 are connected to the monitoring connecting rods 15. The connecting strip 15 not only forms the carrier of the movable hole 17, but also ensures the stability and integrity of the entire monitoring device structure, enabling the various components to work together. The movable hole 17 is set inside the center of the monitoring connecting strip 15, and a strip-shaped monitoring rod 14 is inserted into the movable hole 17. The strip-shaped monitoring rod 14 can move up and down in the movable hole 17, but it cannot rotate in the movable hole 17. This design lays the foundation for accurately measuring the vertical deformation of the expandable corrugated pipe sleeve 5. When the expandable corrugated pipe sleeve 5 undergoes elastic expansion and contraction deformation due to absorbing various displacements of the water supply pipe, the outer wall of its outward protruding part will undergo a vertical position change.

[0024] like Figure 1 and Figure 4As shown, the visual deformation monitoring device 10 also includes a contact strip 12 and a compression spring 13. The bottom end of the strip-shaped monitoring rod 14 is fixed with the contact strip 12. The contact strip 12 and the monitoring connecting strip 15 are parallel to each other. Compression springs 13 are connected between the left and right sides of the center of the contact strip 12 and the monitoring connecting strip 15. The bottom end of the contact strip 12 can be attached to the outer wall of the protruding top of the retractable corrugated sleeve 5, and both compression springs 13 are in a semi-compressed state, which makes the contact... The bottom end of the contact strip 12 is tightly attached to the outer wall of the protruding top of the retractable corrugated sleeve 5. This attachment method ensures that the contact strip 12 can move in real time following the deformation of the retractable corrugated sleeve 5. Since the contact strip 12 is connected to the strip-shaped monitoring rod 14, the vertical deformation of the retractable corrugated sleeve 5 will be transmitted to the strip-shaped monitoring rod 14 through the contact strip 12, so that it moves up and down in the movable hole 17 accordingly. The left and right edges of the bottom of the contact strip 12 are both treated with arc surfaces.

[0025] like Figure 1 and Figure 4 As shown, the visual deformation monitoring device 10 also includes a baffle 19 and a deformation monitoring scale line 20. The baffle 19 is fixed at the top of the strip-shaped monitoring rod 14. When the bottom end of the contact strip 12 is attached to the outer wall of the protruding top of the expandable corrugated sleeve 5, the bottom end of the baffle 19 is attached to the outer wall of the top of the monitoring connecting strip 15, and the baffle 19 is blocked at the top of the monitoring connecting strip 15. The outer wall of the front end of the strip-shaped monitoring rod 14 is provided with a deformation monitoring scale line 20. The deformation monitoring scale line 20 is measured in millimeters. As the strip-shaped monitoring rod 14 moves up and down, the deformation distance generated by the expandable corrugated sleeve 5 upward can be displayed intuitively. The staff only needs to read the value on the scale line to obtain the deformation of the expandable corrugated sleeve 5, and then determine whether the working status of the compensator is normal and whether further inspection and maintenance of the pipeline system is required.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
