Description

Technical Field

[0001] This utility model relates to the field of pipeline leak repair technology, and in particular to a heating pipeline leak repair device. Background Technology

[0002] With the acceleration of urbanization and the large-scale development of centralized heating systems, the safety and stability of heating systems have become important issues in urban energy management. However, traditional heating system fault diagnosis mainly relies on human experience, which has many problems. Therefore, the introduction of artificial intelligence-based heating system fault prediction methods and systems can significantly improve the efficiency and accuracy of fault diagnosis. After a fault is diagnosed, how to complete emergency repairs in a short time becomes one of the important responsibilities of fair management. In the current pipeline repair, it is necessary to use pipes of the same specifications as the damaged pipes for rupture repair. However, due to different pipeline construction periods and different batches of pipes, there may be slight differences in the diameter of pipes of the same specifications. At the same time, due to corrosion and damage, the surface of the damaged pipe wall is uneven, and gaps inevitably appear between the pipes used for sealing leaks and the damaged pipes. These gaps directly affect the subsequent sealing effect.

[0003] In view of this, there is an urgent need for a heating pipeline leak repair device to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Please see the appendix Figure 1-4 A heating pipeline leak repair device, comprising:

[0026] The upper sleeve plate 1, the lower sleeve plate 2, the flexible plate 3, and the tightening assembly 4 are provided. The upper sleeve plate 1 has upper connecting ears 10 integrally formed at both ends of its curved sidewall. The lower sleeve plate 2 has lower connecting ears 20 integrally formed at both ends of its curved sidewall. The upper connecting ears 10 and the lower connecting ears 20 have matching connecting holes 11. The tightening assembly 4 is fixedly connected to the top of the upper sleeve plate 1. The flexible plate 3 is located inside the upper sleeve plate 1. Its two ends pass through the curved sidewall of the upper sleeve plate 1 and are connected to the tightening assembly 4. The flexible plate 3 and the upper sleeve plate 1 are in clearance fit.

[0027] In practical use, first fasten the upper sleeve 1 and the lower sleeve 2 to the damaged pipe. It should be noted that during the fastening process, the upper sleeve 1 needs to be fastened to the damaged pipe, and the position of the flexible plate 3 should cover the damaged pipe. The upper sleeve 1 and the lower sleeve 2 can be basically fixed in position by the connecting holes 11 on the upper connecting ear 10 and the lower connecting ear 11 and the bolts. During the fixing process, the flexible plate 3 will be initially shaped under the pipe and the inner wall of the upper sleeve 1, so that the shape of the flexible plate 3 fits the outer wall of the damaged pipe.

[0028] Specifically, two strip-shaped mounting grooves 12 are provided symmetrically on the inner wall of the curved surface of the upper sleeve plate 1, and a sealing ring 120 is placed in the strip-shaped mounting groove 12.

[0029] Specifically, the tightening assembly 4 includes a U-shaped outer shell 40, a connecting plate 41, and a tightening handle 42. The U-shaped outer shell 40 is fixedly connected to the top of the upper sleeve plate 1. The connecting plate 41 is located inside the U-shaped outer shell 40, and both ends of the connecting plate 41 are slidably connected to the side walls of the U-shaped outer shell 40. The tightening handle 42 passes through the top wall of the U-shaped outer shell 40 and is movably connected to the connecting plate 41. The tightening handle 42 is threadedly connected to the U-shaped outer shell 40. Both ends of the flexible plate 3 pass through the sealing ring 120 and the curved side wall of the upper sleeve plate 1, respectively, and are fixedly connected to the connecting plate 41.

[0030] Considering that under the combined action of the upper sleeve plate 1 and the damaged pipe, although the flexible plate 3 can be forced to complete the basic shaping, it is not possible to achieve the purpose of the flexible plate 3 being tightly fitted to the damaged pipe. Also, considering that the liquid in the pipe cannot be completely drained during pipe repair and emergency repair, if the flexible plate 3 is not sufficiently fitted to the damaged pipe, there will be continuous leakage. Therefore, it is necessary to use external force to further achieve the purpose of the flexible plate 3 being fitted to the damaged pipe. Therefore, a tightening component is set outside the upper sleeve plate 1. The position of the connecting plate 41 is adjusted by the tightening handle 42, thereby changing the actual length of the flexible plate 3 located outside the upper sleeve plate 1. Under the premise that the position of the upper sleeve plate 1 is fixed, the pulling of the flexible plate 3 on the outside of the upper sleeve plate 1 will inevitably make the flexible plate 3 located inside the upper sleeve plate 1 fit more tightly to the damaged pipe.

[0031] Meanwhile, in order to facilitate the change of position of the flexible plate 3 and to prevent water in the damaged pipe from seeping out through the upper sleeve plate 1 during the sealing process, a strip-shaped installation groove 12 is set in the upper sleeve plate 1, and a sealing ring 120 is placed in it. This serves two purposes: first, to reduce the relative friction between the flexible plate 3 and the upper sleeve plate 1 during the change of position; and second, to prevent water from seeping out through the strip-shaped installation groove 12 during the sealing process.

[0032] Specifically, the flexible plate 3 has an anti-corrosion layer on the side away from the upper sleeve plate 1;

[0033] Considering the function of the flexible plate 3, the flexible plate should be made of flexible steel or elastic material with a metal outer layer. In order to prevent the upper sleeve plate 1 from being corroded and damaged again during long-term use, anti-corrosion material should be applied to the flexible plate 3 to isolate the water in the pipe from contact with the upper sleeve plate 1.

[0034] Specifically, the upper sleeve plate 1 and the lower sleeve plate 2 have two sets of matching arc-shaped grooves 13 on their concave sidewalls. The two sets of arc-shaped grooves 13 are located on both sides of the flexible plate 3, and the arc-shaped grooves 13 are provided with matching arc-shaped rubber rings 130.

[0035] Considering that after the damaged pipe is covered by the upper sleeve 1 and the lower sleeve 2, if water leaks again at the same location, and assuming that the upper sleeve 1 and the lower sleeve 2 are not damaged, the water can only seep out from both ends of the upper sleeve 1 and the lower sleeve 2, it is also necessary to seal both ends of the upper sleeve 1 and the lower sleeve 2. An arc-shaped groove 13 is set at both ends of the upper sleeve 1 and the lower sleeve 2, and the sealing effect is achieved by the plasticity of the arc-shaped rubber ring 130 in the arc-shaped groove 13.

[0036] Specifically, the arc-shaped rubber ring 130 has a convex shape at one end and a concave shape at the other end. Considering that the damaged pipe cannot be sealed with a ring-shaped sealing ring, the arc-shaped rubber ring 130 is adopted. At the same time, in order to ensure the sealing performance of the arc-shaped rubber ring 130 with its two ends not connected, one end is concave and the other end is convex. In the uninflated state, the arc-shaped rubber ring 130 can be easily put on the pipe. After being filled with air, it becomes an annular shape and plays a sealing role.

[0037] Specifically, the upper sleeve plate 1 is provided with an inflation through hole 14, and the arc-shaped rubber ring 130 is provided with an inflation tube 131 fixedly connected to it. The end of the inflation tube 131 away from the arc-shaped rubber ring 130 is located in the inflation through hole 14, and the inflation through hole 14 is provided with a matching plug 140. Considering that the position of the arc-shaped rubber ring 130 cannot be directly inflated, an inflation through hole 14 is provided on the upper sleeve plate 1 to allow the inflation tube 131 of the arc-shaped rubber ring 130 to be exposed, and the inflation tube 131 is used to inflate the arc-shaped rubber ring 130. At the same time, in order to prevent someone from accidentally touching the inflation tube 131 and causing the arc-shaped rubber ring 130 to leak air, a plug 140 is also provided on the inflation through hole 14 for protection.

[0038] It should be noted that different methods can be used to deal with the leak depending on the time limit for plugging. If it is only a short-term plugging, the emergency repair device can be removed during the major overhaul, and the damaged pipe can be replaced accordingly. If long-term or permanent use is required, the flexible plate 3 and the arc-shaped rubber ring 130 can basically ensure that there will be no water leakage in the short term. At this time, welding can be performed at the edge of the upper sleeve plate 1 to avoid insufficient sealing caused by air leakage of the arc-shaped rubber ring 130 during long-term use.

[0039] Example 2

[0040] Please see the appendix Figure 5

[0041] Specifically, the lower sleeve plate 2 has an arc-shaped groove 21 on its concave surface, and a matching locking component 5 is provided in the arc-shaped groove 21. The locking component 5 includes an arc-shaped locking plate 50 and a locking handle 51. The arc-shaped locking plate 50 is placed inside the arc-shaped locking plate 50, and the locking handle 51 passes through the lower sleeve plate 2 and is movably connected to the arc-shaped locking plate 50. The locking handle 51 is also threadedly connected to the lower sleeve plate 2.

[0042] Considering that in practical applications the cavity diameter formed by the upper sleeve 1 and the lower sleeve 2 may be too large, the positions of the upper sleeve 1 and the lower sleeve 2 cannot be effectively fixed in this case. To address this issue, an arc-shaped groove 21 is provided in the lower sleeve, and an arc-shaped locking plate 50 is placed in the arc-shaped groove 21. The relative position of the arc-shaped locking plate 50 can be changed by the locking handle 51, thereby changing the gap between the lower sleeve 2 and the damaged pipe, thus fixing the position of the lower sleeve 2. In subsequent installation, the position of the upper sleeve 1 is fixed by the lower sleeve 2.

[0043] Example 3

[0044] Please see the appendix Figure 6

[0045] Considering that there may be a gap between the upper connecting ear 10 and the lower connecting ear 20 in practical applications, the existing arc-shaped rubber ring 130 will be partially exposed, which is not conducive to the use of the arc-shaped rubber ring 130. In order to deal with the above situation, the upper sleeve plate 1 has been slightly modified, and the existing arc-shaped groove 13 has been replaced by an annular placement groove. At the same time, an annular sealing ring can be used to replace the existing arc-shaped rubber ring 130.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
