[0031] Example

[0032] like Figure 1 , 2 As shown, this embodiment discloses a pipeline leakage repair device, which includes two repair assemblies that can be buckled up and down on the pipeline 1. The two repair assemblies each include an arc-shaped outer cover 4, two sealing members 3 respectively sealing at both ends of the arc-shaped outer cover 4, and end covers 2 respectively arranged outside the two sealing members 3 and connected to the arc-shaped outer cover 4.

[0033] like Figure 4 As shown, outer cover locking plates 49 are provided on both sides of the arc-shaped outer cover 4. During installation, one arc-shaped outer cover 4 is supported on the lower half of the leakage position of the pipeline 1 by an external support frame, and then the other arc-shaped outer cover 4 is covered on the upper half of the pipeline 1, and finally the outer cover locking plates 49 of the upper and lower arc-shaped outer covers 4 are locked by bolts, so that the two arc-shaped outer covers 4 are buckled on the pipeline 1, and at this time, the inner wall of the arc-shaped outer cover 4 is in contact with the outer wall of the pipeline 1.

[0034] Rubber gaskets 48 are provided on the buckling contact surfaces of the two arc-shaped outer covers 4 to improve the sealing performance between the two arc-shaped outer covers 4 .

[0035] like Figure 2 , 3 As shown, a concave cavity 41 is provided on the inner wall of the arc-shaped outer cover 4. When the two arc-shaped outer covers 4 are buckled on the pipe 4, the concave cavities 41 on the two arc-shaped outer covers 4 and the outer wall of the pipe 1 together enclose an annular pressure relief cavity. The leakage position of the pipe 1 is connected to the pressure relief cavity, and the water leaking from the pipe 1 enters the pressure relief cavity. In addition, a drain port 46 connected to the pressure relief cavity is provided on the arc-shaped outer cover 4 at the bottom, and a plugging bolt 47 is provided on the drain port 46. Figure 3 shown.

[0036] During installation, the plugging bolt 47 is opened, and the leaked water is discharged from the drain port 46 to release the pressure in the pressure relief chamber to prevent water from overflowing from both ends of the arc-shaped outer cover 4, so as to facilitate the installation of the arc-shaped outer cover 4, the seal 3 and the end cover 2. When all the components are installed, the plugging bolt 47 can be plugged, and the water supply does not need to be shut down during the entire installation process.

[0037] A sealing surface is formed between the inner wall of the arc-shaped outer cover 4 and the outer wall of the pipe 1. In order to improve the sealing effect, two sealing gaskets 42 are arranged on the inner wall of the arc-shaped outer cover 4. The two sealing gaskets 42 are respectively located on both sides of the concave cavity 41. The sealing gaskets 42 on the upper and lower arc-shaped outer covers 4 are connected together to form two annular sealing structures to seal the two ends of the arc-shaped outer cover 4 to prevent water in the pressure relief cavity from overflowing from the two ends of the arc-shaped outer cover 4.

[0038] There are four seals 3 , two of which are arranged at both ends of the upper arc-shaped outer cover 4 , and the other two are arranged at both ends of the lower arc-shaped outer cover 4 . The four seals 3 also form two annular sealing structures to seal the two ends of the arc-shaped outer cover 4 .

[0039] Specifically, Figure 6 As shown, the seal 3 includes a support portion 31, an inclined portion 33 connected to the side of the support portion 31 facing the arc-shaped outer cover 4, and a horizontal portion 34 connected to the front end of the inclined portion 33; a cavity 35 is provided in the horizontal portion 34. The support portion 31, the inclined portion 33 and the horizontal portion 34 can be integrally formed.

[0040] Correspondingly, an outer arc-shaped concave platform 44 and an inner arc-shaped concave platform 45 are provided on the end wall of the arc-shaped outer cover 4. The inner arc-shaped concave platform 45 is located inside the outer arc-shaped concave platform 44, and the diameter of the inner arc-shaped concave platform 45 is smaller than the diameter of the outer arc-shaped concave platform 44. Figures 2 to 4 shown.

[0041] The four end covers 2 are combined to form two annular covers that are sealed on the outside of the sealing member 3. Figure 5 As shown, the end cover 2 includes a gusset plate 21, an end cover connecting plate 23 and an end plate 22 respectively connected to the gusset plate 21. Correspondingly, the arc-shaped outer cover 4 is provided with an arc-shaped outer cover connecting plate 43, and the outer cover connecting plate 43 and the end cover connecting plate 23 are connected by a plurality of bolts.

[0042] When the bolts are tightened, the end plate 22 abuts against the abutting portion 31 and pushes the seal 3 toward the arc-shaped outer cover 4, so that the horizontal portion 34 is inserted into the inner arc-shaped concave platform 45, and the front end of the inclined portion 33 is inserted into the outer arc-shaped concave platform 44. As the bolts are tightened continuously, the axial thrust on the seal 3 increases, and the inclined portion 33 is gradually pressed toward one side of the pipeline by the side wall of the outer arc-shaped concave platform 44 when moving forward, so that the inner wall of the entire seal 3 is closely attached to the outer wall of the pipeline 1, and the contact surfaces between the upper and lower seals 3 on the same side are more closely attached, thereby improving the sealing performance.

[0043] At the same time, the front end of the horizontal portion 34 abuts against the end wall of the inner arc-shaped recess 45. Since the cavity 35 is provided in the horizontal portion 34, the horizontal portion 34 expands when squeezed to seal the space between the inner arc-shaped recess 45 and the outer wall of the pipe, further improving the sealing performance.

[0044] When all components are installed, the buckle plate 21 is buckled outside the sealing member 3 and the arc-shaped outer cover 4 , thereby covering the gap between the sealing member 3 and the end of the arc-shaped outer cover 4 .

[0045] In addition, a reinforcing rib 32 is provided in the abutting portion 31 , which can improve the strength of the sealing member 3 and prevent the abutting portion 31 from being deformed when the end cover 2 pushes the sealing member 3 .

[0046] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0047] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the utility model, and these solutions also belong to the disclosure scope of the utility model and fall within the protection scope of the utility model. Those skilled in the art should understand that the utility model specification and its drawings are illustrative and do not constitute a limitation of the claims. The protection scope of the utility model is defined by the claims and their equivalents.
