DETAILED DESCRIPTION

[0023] The technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0024] In order to better understand the purposes, structures and functions of the utility model, a pipeline leak repairing device according to the utility model will be described in detail below with reference to the drawings.

[0025] Figure 1 The overall structure of the pipeline leak repairing device according to the utility model is schematically shown. In the embodiment shown in Figure 1 The pipeline leak repairing device comprises a leak repairing mechanism 1, the leak repairing mechanism 1 comprises a first connecting rod 11, a second connecting rod 12 corresponding to the first connecting rod 11, and a sealing cloth 13 arranged between the first connecting rod 11 and the second connecting rod 12 and fixed together with the first connecting rod 11 and the second connecting rod 12.

[0026] In this embodiment, the sealing cloth 13 is made of flexible material. In this way, the sealing part 13 can be deformed along the contour of the pipeline (not shown in the drawing). Thus, the sealing part 13 can wrap the pipeline. In this arrangement, the sealing part 13 can block the water leakage of the pipeline.

[0027] In one embodiment, as shown in Figure 1 The first connecting rod 11 and the second connecting rod 12 are configured to be fixed together. In this way, when the first connecting rod 11 and the second connecting rod 12 are fixed together, the sealing cloth 13 can be attached to the pipeline, so that the sealing cloth 13 can stably block the water leakage of the pipeline.

[0028] In this arrangement, when it is necessary to block the water leakage of the pipeline (not shown in the drawing), the sealing cloth 13 is first arranged at the water leakage position of the pipeline. At the same time, the first connecting rod 11 and the second connecting rod 12 are respectively subjected to forces in opposite directions along the sealing cloth 13, so that the sealing cloth 13 forms a wrapping around the pipeline.

[0029] In this process, the sealing cloth 13 will cover the pipe leakage. At this time, the first connecting rod 11 and the second connecting rod 12 are relatively fixed together. Thus, the sealing cloth 13 can stably block the pipe leakage, thereby realizing the pipe leakage repair work.

[0030] In one embodiment, as shown in Figure 1 The sealing cloth 13 is made of a material that cannot be infiltrated by fluid, such as rubber, polytetrafluoroethylene coated fabric, and super-hydrophobic coated composite material. In this way, the sealing cloth 13 can stably block the pipe leakage, thereby avoiding the fluid in the pipe from penetrating out along the sealing cloth 13.

[0031] In addition, in this arrangement, the sealing cloth 13 also allows elastic deformation. In this way, the sealing effect of the sealing cloth 13 can be improved. Specifically, when the sealing cloth 13 is located on the pipe, the sealing cloth 13 can be wrapped along the contour of the pipe, and in this process, the sealing cloth 13 can also elastically deform according to the contour of the pipe. During the elastic deformation of the sealing cloth 13, the sealing cloth 13 will continue to apply force to the pipe. Thus, the sealing cloth 13 can further block the pipe leakage, thereby improving the sealing effect.

[0032] According to a preferred embodiment of the present application, as shown in Figure 1 The sealing cloth 13 is configured to have a diameter smaller than that of the pipe. In this way, when the sealing cloth 13 is wrapped around the pipe and the first connecting rod 11 and the second connecting rod 12 are relatively fixed together, the sealing cloth 13 can continuously apply force to the pipe, thereby stably blocking the pipe leakage. Thus, the sealing effect can be further improved.

[0033] In this arrangement, when it is necessary to block the pipe (not shown in the figure) leakage, the sealing cloth 13 is first arranged at the pipe leakage. At the same time, the first connecting rod 11 and the second connecting rod 12 are respectively applied with forces in opposite directions along the sealing cloth 13.

[0034] In this process, the sealing cloth 13 will continuously elastically deform. At this time, the first connecting rod 11 and the second connecting rod 12 are continuously applied with forces until they are relatively fixed together. In this way, the sealing cloth 13 can be wrapped around the pipe, and after being wrapped, the sealing cloth 13 can continuously apply force to the pipe. Thus, the sealing cloth 13 can stably block the pipe leakage, thereby realizing the pipe leakage repair work.

[0035] In one embodiment, as shown inFigure 2 As shown in the figure, the pipeline leak repairing device further comprises a sealing ring 2. In the embodiment, the sealing ring 2 is arranged at both ends of the sealing cloth 13 and is configured to allow abutting with the pipeline. In this way, when the sealing cloth 13 is wrapped around the pipeline, the sealing ring 2 can be abutted with the pipeline, so that the two ends of the sealing cloth 13 can be sealingly connected with the pipeline. Thus, the repairing effect can be further improved.

[0036] In the embodiment, as shown in the figure, Figure 2 the elastic modulus of the sealing ring 2 is set to be less than that of the sealing cloth 13. In this arrangement, when the sealing cloth 13 is arranged on the pipeline, the sealing ring 2 can fix the sealing cloth 13. Thus, the sealing cloth 13 can be tightly connected with the pipeline, so that the sealing cloth 13 can not be separated from the pipeline when subjected to the force generated by the fluid leakage in the pipeline. In this way, the connection between the sealing cloth 13 and the pipeline can be further strengthened, so that the repairing effect of the device can be further improved.

[0037] In one embodiment, as shown in the figure, Figure 1 the two leak repairing mechanisms 1 are arranged to be buckled with each other. Specifically, in the embodiment, the first connecting rod 11 and the second connecting rod 12 arranged on the two leak repairing mechanisms 1 are correspondingly arranged. In this way, the two buckled leak repairing mechanisms 1 can jointly form the cavity 14 wrapping the pipeline.

[0038] Meanwhile, in the illustrated embodiment, as shown in the figure, Figure 1 the pipeline leak repairing device further comprises a fixing mechanism 3, which is configured to allow the two buckled leak repairing mechanisms 1 to be fixed with each other. Specifically, the fixing mechanism 3 can fix the first connecting rod 11 and the second connecting rod 12 arranged on the two leak repairing mechanisms 1 with each other. Thus, the two buckled leak repairing mechanisms 1 can form the cavity 14 wrapping the pipeline in a selected manner. In this arrangement, the device can be conveniently connected with the pipeline.

[0039] In one embodiment, as shown in the figure, Figure 1 the fixing mechanism 3 comprises a connecting portion 31 arranged on one side of the first connecting rod 11 and the second connecting rod 12, and a connecting hole 32 arranged on the other side of the first connecting rod 11 and the second connecting rod 12, the connecting hole 32 being configured to allow the connecting portion 31 to pass through.

[0040] Meanwhile, the fixing mechanism 3 further comprises a limiting part 33 arranged on the connecting part 31, which is configured to limit the first connecting rod 11 and the second connecting rod 12 on the other side when the connecting part 31 and the limiting part 33 are connected together. In this way, the two leak repairing mechanisms 1 buckled together can be fixed together in a selected manner, thereby forming the cavity 14 wrapping the pipeline in a selected manner.

[0041] According to a preferred embodiment of the present application, as shown in Figure 3 The connecting part 31 is arranged as a threaded column, and the limiting part 33 is arranged as a nut allowing mutual cooperation with the threaded column. In this way, when the threaded column and the nut are buckled together, the two leak repairing mechanisms 1 buckled together can be stably connected together.

[0042] However, it should be noted that the connecting part 31 is arranged in multiple and distributed along the axis direction of the first connecting rod 11 and the second connecting rod 12. Meanwhile, the connecting hole 32 and the limiting part 33 correspond to the connecting part 31. In this way, the connection between the two leak repairing mechanisms 1 can be further strengthened.

[0043] In an embodiment, as shown in Figure 1 The pipeline leak repairing device further comprises a sealing part 4, which is arranged in two and allows to pass through the connecting part 31 to be arranged between the first connecting rod 11 and the second connecting rod 12.

[0044] In the present embodiment, as shown in Figure 2 The sealing part 4 is made of any material capable of elastic deformation and unable to be infiltrated by fluid, such as rubber, polytetrafluoroethylene coated fabric, and super-hydrophobic coating composite material. In this way, the sealing property of the buckling part of the two leak repairing mechanisms 1 can be improved.

[0045] Specifically, when the sealing part 4 is arranged on the connecting part 31 and located between the two leak repairing mechanisms 1, the limiting part 33 will drive the first connecting rod 11 and the second connecting rod 12 on the other side to move towards the first connecting rod 11 and the second connecting rod 12 on one side as the limiting part 33 continuously moves along the connecting part 31. In this process, the first connecting rod 11 and the second connecting rod 12 on both sides will respectively apply force to the sealing part 4 located therebetween.

[0046] At this time, the sealing part 4 will continuously be elastically deformed to seal the gap between the two buckling positions of the two repairing mechanisms 1. Thus, a closed cavity 14 is formed to prevent the fluid in the pipeline from leaking out of the cavity 14 along the connection position of the two repairing mechanisms 1.

[0047] According to a preferred embodiment of the present application, the sealing part 4 is provided with four sealing parts, and each of the four sealing parts abuts against the first connecting rod 11 and the second connecting rod 12.

[0048] The operation of the pipeline repairing device according to the present application is as follows.

[0049] First, the two repairing mechanisms 1 are buckled at the position of the pipeline leakage, and the sealing part 4 is arranged in the connecting part 31. At the same time, the two repairing mechanisms 1 are respectively subjected to the action force, and the action force is opposite. In this process, the two repairing mechanisms 1 buckled together move towards each other. At this time, the sealing cloth 13 will continuously be elastically deformed.

[0050] At the same time, the two repairing mechanisms 1 buckled together are continuously subjected to the opposite action force until the connecting part 31 passes through the connecting hole 32. At this time, the limiting part 33 is arranged on the connecting part 31 and is fixed relative to the connecting part 31, so that the two repairing mechanisms 1 buckled together are stably connected.

[0051] At this time, the limiting part 33 is continuously subjected to the action force, so that the limiting part 33 continuously moves along the connecting part 31. In this process, the limiting part 33 drives the first connecting rod 11 and the second connecting rod 12 on the other side to move towards the first connecting rod 11 and the second connecting rod 12 on one side.

[0052] Thus, the first connecting rod 11 and the second connecting rod 12 on both sides respectively apply the action force to the sealing part 4 located between them. In this process, the sealing part 4 will continuously be elastically deformed to seal the gap between the two buckling positions of the two repairing mechanisms 1. Thus, a closed cavity 14 is formed to prevent the fluid in the pipeline from leaking out of the cavity 14 along the connection position of the two repairing mechanisms 1, thereby realizing the repairing work.

[0053] Finally, it is explained that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application. The technical solutions of the present application should be covered in the scope of the claims of the present application.
