Description
Technical Field
[0001] This utility model relates to the field of pipeline waterproofing and repair technology, specifically to a wrap-around composite sealing tape device for waterproofing and repairing leakage on the outer wall of a pipeline. Background Technology
[0002] In the chemical and various civil drainage fields, pipeline systems, as important fluid transmission carriers, are crucial for safe, stable, and leak-free operation.
[0003] However, during long-term use, due to various factors, leakage problems inevitably occur on the outer wall of the pipeline, especially at welds and joints. Such leakage not only causes resource waste and economic losses, but may also lead to environmental pollution, equipment downtime, and even safety accidents.
[0004] Therefore, existing technologies have made many improvements regarding pipeline repair after leakage. For example, Chinese patent CN210687471U discloses a pipeline repair joint, which includes an upper shell and a lower shell. Sealing grooves are formed inside both the upper and lower shells, and sealing gaskets are embedded within these grooves. A clamping assembly is provided at one end of the outer shell along its radial direction. One end of the upper shell and one end of the lower shell are clamped together by the clamping assembly. An upper support lug is fixed at one end of the upper shell, and a lower support lug is provided between two outer upper support lugs. The lower support lug is fixed at one end of the lower shell. A rotating hole is formed on each of the upper and lower support lugs, and a rotating shaft passes through the rotating hole. The rotating shaft is positioned along the axial direction of the outer shell, and external threads are provided at both ends of the rotating shaft. First fastening nuts are threaded to both ends of the rotating shaft, and the opposing side walls of the two first fastening nuts abut against the opposing side walls of the two outer upper support lugs. This utility model effectively prevents the upper or lower shell from being lost during storage, transportation, or installation of the pipeline repair joint.
[0005] However, the following shortcomings still exist in its use:
[0006] 1. Pipeline repair joints have limited adjustment capabilities for different pipe diameters, and when performing sealing treatment, they can only be adapted to pipes of a specific diameter, lacking adaptability and flexibility.
[0007] 2. It is fixed by multiple fastening nuts, which makes the operation more cumbersome during use.
[0008] Based on this, the present invention provides a wrap-around composite sealing tape device for waterproofing and repairing leaks in the outer wall of pipes to solve the above problems. Utility Model Content

[0014] Furthermore, the guide assembly includes guide posts, and the fixed plate has guide holes that are slidably connected to the guide posts. The number of guide holes is the same as that of the guide posts and they correspond one-to-one.
[0015] Furthermore, the limiting component includes a limiting block, which is fixedly connected to the lower end of the guide post, and the inner diameter of the limiting block is larger than the inner diameter of the guide post and the guide hole.
[0016] Furthermore, the winding and fixing component includes fixing hooks, with multiple sets of fixing hooks equidistantly distributed in the horizontal direction.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0032] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
[0033] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A wound composite sealing tape device for waterproofing and repairing leaks in the outer wall of a pipe includes a constraint plate 1 and a sealing ring 2. The constraint plate 1 is fixedly connected to the outer wall of the sealing ring 2. The device also includes a fine-adjustable sealing winding mechanism 3, which is connected to the constraint plate 1.
[0034] The fine-tuning sealing and winding mechanism 3 includes a fixed plate 311, a movable plate 312, a guide assembly, a limiting assembly, an adjusting assembly, and a winding and fixing assembly. The fixed plate 311 is fixedly connected to one end of the constraint pressure plate 1. Two sets of guide assemblies are symmetrically distributed about the adjusting assembly. Each set of guide assemblies has multiple equidistant distributions along the fixed plate 311. The guide assemblies are connected to the fixed plate 311 and the movable plate 312 respectively. The number of limiting assemblies is the same as that of the guide assemblies and they correspond one-to-one. The limiting assemblies are connected to the guide assemblies. The adjusting assembly is connected to the fixed plate 311 and the movable plate 312 respectively. The winding and fixing assembly is connected to the movable plate 312 and the constraint pressure plate 1 respectively.
[0035] The constraint plate 1 is a flexible stainless steel sheet with good toughness and mechanical strength.
[0036] The sealing ring 2 is made of rubber with good waterproof properties.
[0037] The adjustment assembly includes a rotating ring 316 and an adjusting bolt 317. The rotating ring 316 is rotatably connected to the lower wall of the moving plate 312. The lower end of the rotating ring 316 is fixedly connected to the upper end of the adjusting bolt 317. The fixed plate 311 has an adjustment hole 318 in the middle that is threadedly connected to the adjusting bolt 317.
[0038] The guide assembly includes a guide post 313, and a guide hole 314 is provided on the fixing plate 311 to be slidably connected to the guide post 313. The number of guide holes 314 is the same as that of the guide post 313 and they correspond one-to-one.
[0039] The limiting component includes a limiting block 315, which is fixedly connected to the lower end of the guide post 313. The inner diameter of the limiting block 315 is larger than the inner diameter of the guide post 313 and the guide hole 314.
[0040] The winding and fixing assembly includes fixing hooks 320. Multiple sets of fixing hooks 320 are equidistantly distributed in the horizontal direction. The lower end of each set of fixing hooks 320 is fixedly connected to the moving plate 312. Multiple sets of fixing grooves 321 for accommodating fixing hooks 320 are opened above the other end of the constraint pressure plate 1. Multiple sets of fixing grooves 321 are equidistantly distributed in the vertical direction. The number of fixing grooves 321 in each set is the same as the number of sets of fixing hooks 320 and they correspond one-to-one.
[0041] The front end of the fixing hook 320 is an L-shaped structure, and the groove of the fixing groove 321 is the same L-shaped structure. The volume of the fixing groove 321 is greater than the volume of the fixing hook 320. Let the surface of the fixing hook 320 that contacts the fixing groove 321 when it is placed into the fixing groove 321 be the contact surface. Then the contact surface in the fixing groove 321 is set to be arc-shaped.
[0042] A fixing layer 322 is fixedly connected to the lower end of the fixing groove 321. The fixing layer 322 is a rubber layer, which is used to make the contact between the fixing hook 320 and the fixing groove 321 more reliable.
[0043] In this utility model, when the outer wall of the pipe needs to be repaired due to water leakage, the sealing ring 2 and the restraining pressure plate 1 are wrapped around the leakage point. With the cooperation of the fixing layer 322, the fixing hook 320 is placed in the corresponding fixing groove 321 according to the diameter of the pipe to be repaired, so that the inner diameter of the sealing ring 2 is slightly smaller than the outer diameter of the pipe. Because the sealing ring 2 is made of rubber, it can fit well on the outer wall of the pipe and play a sealing role.
[0044] If the winding tightness is insufficient at this time, fine-tuning is required. Rotate the adjusting bolt 317 in the adjusting hole 318. The movement of the adjusting bolt 317 causes the rotating ring 316 to move. The movement of the rotating ring 316 causes the moving plate 312 to move relative to the fixed plate 311. The movement of the moving plate 312 causes the fixed hook 320 to move. During the movement, the guide post 313, the guide hole 314 and the limiting block 315 play a guiding and limiting role, so that fine-tuning can be performed better.
[0045] Example 2: In some embodiments, such as Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, a damping shaft 319 is fixedly connected to the lower end of the fixed hook 320, and the lower end of the damping shaft 319 is rotatably connected to the moving plate 312.
[0046] In this utility model, when the pipe needs repair due to water leakage and the fixing hook 320 is placed in the corresponding fixing groove 321 for fixing, the fixing hook 320 and the damping shaft 319 can rotate to adjust the angle so that the fixing hook 320 can be better placed into the fixing groove 321. At the same time, due to the damping effect of the damping shaft 319 and the limiting effect of the fixing groove 321, the stability of the fixing hook 320 after fixing can also be guaranteed.
[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
