Technical Field

[0001] This utility model relates to the field of gas pipeline repair technology, specifically a repair and reinforcement device for gas pipelines crossing straits. Background Technology

[0002] Existing gas pipelines refer to pipelines that transport natural gas from extraction sites or processing plants to urban gas distribution centers or industrial users; they are also known as gas transmission pipelines. Natural gas is a clean fuel with high calorific value, easy to transport and store, and abundant in resources. The vigorous development of the gas industry has made a significant contribution to creating green cities, facilitating people's lives, and improving enterprise production efficiency. After long-term use, gas pipelines may experience damage and leakage, thus requiring workers to repair them using repair equipment. After repair, specialized reinforcement devices are needed for further protection. However, existing gas pipeline repair and reinforcement devices have limitations in their use. The protective effect after reinforcement is not good enough, and the repaired parts are subject to long-term seawater erosion, which affects the repair effect. Therefore, there is room for improvement. Utility Model Content

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3 As shown in this embodiment, a gas pipeline repair and reinforcement device for crossing a strait includes two symmetrically arranged reinforcement sleeves 1. Each reinforcement sleeve 1 has a through groove 2 for the gas pipeline to pass through. An installation ring 7 is fixed to the outer opening of the through groove 2. The cross-section of the reinforcement sleeve 1 is semi-circular. A connecting flange is fixed to the outer side of one end of the installation ring 7. A rubber ring 8 is installed at the inner opening of the through groove 2. Mounting seats 3 are symmetrically arranged at the ends of the two reinforcement sleeves 1. A connecting cylinder 4 is installed on the surface of the mounting seat 3 at one end of the reinforcement sleeve 1, and a mounting screw hole 6 is opened on the surface of the mounting seat 3 at the other end of the reinforcement sleeve 1. A connecting bolt 5 is screwed into the mounting screw hole 6, and one end of the connecting bolt 5 is connected to the connecting cylinder 4. Protective components are arranged inside the two reinforcement sleeves 1. The protective components include components symmetrically arranged on the two... The inner side of the reinforcing sleeve 1 has a protective cylinder 9 with a corrugated surface. The inner diameter of the protective cylinder 9 is equal to the inner diameter of the opening of the through groove 2. One end of the protective cylinder 9 is fixedly connected to the surface of the rubber ring 8. The other end of the two protective cylinders 9 is equipped with a connecting magnetic ring 10. The connecting magnetic ring 10 is fixedly connected to the protective cylinder 9 by bolts. The two connecting magnetic rings 10 have different magnetic properties on their surfaces. The surface of the connecting magnetic ring 10 is provided with mounting holes 14 at equal angles. A connecting screw 12 is inserted through the mounting hole 14. Limiting nuts 13 are symmetrically fitted at both ends of the connecting screw 12. This facilitates the protection of the repaired part of the gas pipeline, making the repaired part less susceptible to seawater corrosion, reducing the possibility of further damage, reducing the number of times workers need to repair the gas pipeline, and extending the service life of the gas pipeline. It has good practicality.

[0021] like Figure 2 and Figure 4As shown, the mounting ring 7 has a sealing assembly inside, which includes sealing rings 11 evenly spaced inside the mounting ring 7. The inner wall of the mounting ring 7 has mounting ring grooves 15 evenly spaced for the sides of the sealing rings 11 to engage. Suction cups 16 are provided at equal angles on the outer side of the sealing rings 11. A fixing stud 17 is fixed to one end of the suction cup 16. The outer surface of the sealing ring 11 has fixing grooves 18 at equal angles for the fixing stud 17 to be screwed into. The suction cups 16 are adsorbed and connected to the inner surface of the mounting ring grooves 15. The width of the outer surface of the sealing ring 11 is greater than the width of the opening of the mounting ring groove 15. The inner surface of the sealing ring 11 is beveled, which facilitates the sealing performance when the gas pipeline is connected to the mounting ring 7, making it difficult for seawater to flow into the interior of the protective cylinder 9 through the gap between the mounting ring 7 and the gas pipeline. This can further improve the protective effect and also reduce the wear between the mounting ring 7 and the gas pipeline, resulting in good practical effect.

[0022] This utility model provides a repair and reinforcement device for gas pipelines crossing straits. The specific working principle is as follows: During the initial installation of the sealing components, the suction cup 16 is first pushed towards the outer surface of the sealing ring 11, aligning one end of the fixing stud 17 with the opening of the fixing groove 18. Then, the suction cup 16 is rotated so that the fixing stud 17 can be screwed into the fixing groove 18. This process continues until an appropriate number of suction cups 16 are installed. Next, the sealing ring 11 is pushed towards the interior of the mounting ring 7, aligning the outer surface of the sealing ring 11 with the opening of the mounting ring groove 15 on the inner wall of the mounting ring 7. Then, the surface of the sealing ring 11 is pressed, allowing it to engage with the interior of the mounting ring groove 15. During this engagement, the outer surface of the sealing ring 11 undergoes slight deformation until the suction cup 16 adheres to the inner surface of the mounting ring groove 15, thus allowing the sealing ring 11 to be securely installed inside the mounting ring 7. The above steps can then be repeated to install other sealing rings 11. When the gas pipeline passes through later... When the sealing ring 7 is installed inside, the surface of the sealing ring 11 will be tightly pressed against the surface of the gas pipeline, making it difficult for seawater to corrode the repaired part of the gas pipeline, resulting in good practical effect. In the early stage of installing the protective components, the two protective cylinders 9 are first melt-connected to the surfaces of the rubber rings 8 on the inner side of the two reinforcing sleeves 1, so that one end of the protective cylinder 9 can be limited and fixed. Then, the other ends of the two protective cylinders 9 are gradually pulled closer, and then the connecting screw 12 is inserted into the mounting hole 14 on the surface of the connecting magnetic ring 10. Then, the two limiting nuts 13 are screwed into the end of the connecting screw 12, so that the two limiting nuts 13 can limit the connecting magnetic ring 10. When the fixing device is used to reinforce the gas pipeline later, the two protective cylinders 9 will be limited and fitted outside the gas pipeline, and the surfaces of the two connecting magnetic rings 10 will be magnetically connected, making it difficult for seawater to corrode the repaired part of the gas pipeline, which can improve the reinforcement and protection effect of the gas pipeline and has good practicality.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
