Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and in particular to a rapid sealing device for pipeline leaks in water conservancy engineering. Background Technology

[0002] In water conservancy projects, pipeline systems play a crucial role in transporting water. However, due to various reasons, such as material aging and external damage, pipeline leaks occur frequently. Traditional methods for sealing pipeline leaks are often inefficient, complex to operate, and inadequate for handling emergencies. Some rapid sealing devices, after installation, suffer damage and leakage due to continued use and the expansion of the rupture opening. To address this problem, this invention proposes a rapid pipeline leak sealing device for water conservancy projects. Utility Model Content

[0003] The purpose of this utility model is to provide a rapid sealing device for pipeline leaks in water conservancy projects, so as to solve the above-mentioned technical problems. To achieve the above purpose, this utility model adopts the following technical solution: A rapid sealing device for pipeline leaks in water conservancy projects includes an internal quick-sealing structure and an external protective structure. The internal quick-sealing structure is located inside the external protective structure and can be fixed at any angle inside the external protective structure.

[0004] Based on the above technical solution, the internal quick-sealing structure consists of a folded tube sleeve, an internal rubber sealing ring, and sealing screws. The internal rubber sealing ring is located inside the folded tube sleeve and is tightly attached to the inner wall of the folded tube sleeve. The other side of the folded tube sleeve is connected by a connecting pin, and the folded tube sleeve can be folded rotatably by the connecting pin. The outer side of the open end of the folded tube sleeve is provided with a protruding fixing edge, and the opposite protruding fixing edge on the folded tube sleeve is fixed by sealing screws. The inner sidewall of the folded tube sleeve has multiple diameter-changing slots, and the diameter of the multiple diameter-changing slots gradually decreases from the center to both ends. The internal rubber sealing ring is tightly attached to the diameter-changing slots. The total width of the folded tube sleeve and the protruding fixing edge is less than the width of the inner sidewall of the external protective structure.

[0005] Based on the above technical solution, the external protective structure consists of an outer sleeve, a sleeve fixing edge seal, a sleeve end sealing gasket, and sealing screws. The outer sleeves are arranged opposite each other, and the sleeve fixing edges are arranged opposite each other on both sides of the outer sleeves. The sleeve fixing edges on both sides of the two sets of outer sleeves are provided with corresponding and close-fitting sealing gaskets. The sleeve end sealing gaskets are arranged on both sides between the two sets of outer sleeves, and the sealing screws are fixed on the oppositely arranged sleeve fixing edges.

[0006] Based on the above technical solution, the end sealing gasket of the sleeve is composed of an open rubber ring, an inner sealing ring convex line, and an outer positioning convex line. The inner sealing ring convex lines are arranged side by side on the inner sidewall of the open rubber ring, and the outer positioning convex line is arranged on the outer side of the open rubber ring. The open rubber ring, the inner sealing ring convex line, and the outer positioning convex line are integrally formed. The inner sidewalls of both ends of the outer sleeve are provided with embedded concave grooves. The open rubber ring is tightly attached to the inner sidewalls of both ends of the outer sleeve. The outer positioning convex line is embedded in the embedded concave groove. The outer sleeve is provided with an internal component receiving cavity. The internal quick-sealing structure is integrally set in the internal component receiving cavity. The total width of the folded sleeve and the externally protruding fixed edge is less than the width of the inner sidewall of the internal component receiving cavity.

[0007] Compared with the prior art, this utility model has the following advantages: This utility model optimizes the setting of the rapid sealing device for water conservancy projects, changes the single-layer sealing structure of the traditional sealing device, and improves it into a double-layer sealing structure. The inner layer can quickly achieve the sealing effect, while the outer sealing structure can provide longer-lasting protection, reduce the risk of water conservancy pipelines breaking again, extend service life, improve sealing tightness and stability, and is suitable for widespread use.

The outer side of the open end of the folded tube sleeve 3 is provided with a protruding fixing edge 7. The protruding fixing edge 7 on the opposite side of the folded tube sleeve 3 is fixed by sealing screws 5. The inner side wall of the folded tube sleeve 3 has multiple diameter-changing slots 8. The diameter-changing slots 8 are set with the diameter gradually decreasing from the center to both ends. The internal rubber sealing ring 4 is tightly attached to the diameter-changing slots 8. The total width of the folded tube sleeve 3 and the protruding fixing edge 7 is less than the width of the inner side wall of the outer protective structure 2.

[0019] The above describes the components of the internal quick-sealing structure 1, as well as the relative positions and connections of its internal components, and corresponds to the attached diagram. Figure 2 Appendix Figure 3 Appendix Figure 4 .

[0020] The external protective structure 2 consists of an external sleeve 9, a sleeve fixing edge seal 10, a sleeve end sealing gasket 11, and a sealing screw 5. The external sleeves 9 are arranged opposite each other, and the sleeve fixing edge seals 10 are arranged opposite each other on both sides of the external sleeves 9. The sleeve fixing edge seals 10 on both sides of the two sets of external sleeves 9 are provided with a surface sealing gasket 17 on their corresponding close contact surfaces. The sleeve end sealing gasket 11 is arranged on both sides between the two sets of external sleeves 9. The sealing screw 5 is fixed on the oppositely arranged sleeve fixing edge seals 10.

[0021] The above describes the components and their connection relationships of the external protective structure 2, as shown in the attached diagram. Figure 5 .

[0022] The end sealing gasket 11 of the sleeve is composed of an open rubber ring 12, an inner sealing ring convex line 13, and an outer positioning convex line 14. The inner sealing ring convex line 13 is arranged side by side on the inner sidewall of the open rubber ring 12, and the outer positioning convex line 14 is arranged on the outer side of the open rubber ring 12.

[0023] The above describes the partial details and corresponding positional relationships of the external protective structure 2, as well as its positional and size relationships relative to the internal quick-sealing structure 1. (See attached diagram.) Figure 6 .

[0024] In practical applications, when a leak occurs in a water conservancy pipeline, operators can quickly carry this rapid sealing device to the leak site. First, based on the location and angle of the leak, adjust the angle of the internal quick-sealing structure 1 within the external protective structure 2 to ensure accurate alignment of the internal quick-sealing structure 1 with the leak point. Next, unfold the folded sleeve 3, allowing the internal rubber sealing ring 4 to fit tightly against the inner wall around the leak. The multi-section variable-diameter groove 8, positioned close to the leak point, provides sufficient water flow space, offering a high-pressure buffer during the gradual fixing process. Then, secure the protruding fixing edge 7 on the opposing folded sleeve 3 with sealing screws 5 to prevent displacement of the internal quick-sealing structure 1 during use. Simultaneously, the two sets of external sleeves 9 of the external protective structure 2 are interconnected, and the entire internal quick-sealing structure 1 is contained within the internal component receiving cavity 16. The faceted sealing gasket 17 on the sleeve fixing edge 10 can provide a sealing effect after sealing. The open rubber ring 12 of the sleeve end sealing gasket 11 is tightly attached to the inner sidewalls of both ends of the external sleeve 9. The inner sealing ring convex line 13 further enhances the sealing effect, and the outer positioning convex line 14 is embedded in the inner recessed groove 15 to ensure the stability and sealing performance of the external protective structure 2. Finally, the sleeve fixing edges 10 of the two sets of external sleeves 9 are fixed together by the sealing screws 5 to complete the entire sealing process. The double-layer sealing structure of this device enables the inner layer to quickly achieve the sealing effect, while the outer layer provides long-term protection, effectively reducing the risk of pipeline re-rupture in water conservancy projects, extending service life, and improving the tightness and stability of the sealing.
