The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] Please combine Figures 1 to 5As shown, this utility model provides a corrugated pipe airtightness testing device, which includes a testing pool 1 and an air supply assembly fixedly installed on the testing pool 1.

[0028] A rotating plate 2 is provided at both ends of the detection pool 1 along its length. The two rotating plates 2 are fixedly connected by a connecting column 11. A motor 8 is fixedly installed on the outer surface of the detection pool 1. The output end of the motor 8 is fixedly connected to one of the rotating plates 2 through a shaft 7. The shaft 7 is rotatably connected to the detection pool 1.

[0029] Multiple extension plates 3 are fixedly installed at equal intervals along the circumference of the rotating plate 2. Each extension plate 3 is fixedly installed with a sealing ring 4. The two ends of the bellows along the length direction are respectively installed in two sealing rings 4.

[0030] Each rotating plate 2 has a rotating ring 5 on one side, and a fixed ring 6 is rotatably mounted on the rotating ring 5. The fixed ring 6 is fixedly connected to the detection pool 1 and the fixed ring 6 is fixedly connected to the air supply assembly.

[0031] Multiple first connecting pipes 12 are fixedly installed on the rotating ring 5. The multiple first connecting pipes 12 are arranged one-to-one with multiple sealing rings 4. One end of the first connecting pipe 12 is connected to the inner side of the sealing ring 4. A first valve 14 is fixedly installed on one end of each first connecting pipe 12. A second pressure relief head 18 is fixedly installed on the extension plate 3. The second pressure relief head 18 is connected to the inner side of the sealing ring 4. A second pressure relief valve 19 is fixedly installed on the second pressure relief head 18.

[0032] When testing the airtightness of the bellows, the bellows is installed between two oppositely arranged sealing rings 4. The motor 8 is started to rotate the rotating ring 5, causing the bellows to be submerged below the liquid surface. At this time, the air supply component delivers air into the interior of the rotating ring 5. The first valve 14 on one of the first connecting pipes 12 is opened, and the first connecting pipe 12 is connected to the inner side of the submerged sealing ring 4. The air in the rotating ring 5 then enters the bellows. At this time, observe whether there are bubbles emerging in the water. If no bubbles emerge, it is a qualified product. During the testing process, since multiple sealing rings 4 are provided on the rotating plate 2, multiple bellows can be installed between the two rotating plates 2. The bellows between other sealing rings 4 can be replaced while testing the airtightness of the bellows, thereby improving the testing efficiency of the bellows.

[0033] More than three extension plates 3 can be installed on the rotating plate 2, so that more than three bellows can be installed between the rotating plates 2 at the same time. One of them is located below the liquid surface to test the air tightness, and another is located above the liquid surface to drain the water. The staff then replaces the drained bellows. When replacing, the second pressure relief valve 19 starts, and the gas in the bellows is discharged through the second pressure relief head 18.

[0034] To ensure the sealing between the bellows end and the sealing ring 4, a rubber ring 20 is fixedly installed on the inner surface of each sealing ring 4. The end of the bellows can be inserted into the inside of the rubber ring 20. The rubber ring 20 can deform, so that there is a good seal between the rubber ring 20 and the bellows.

[0035] A cavity is formed between the inner surface of the rubber ring 20 and the sealing ring 4. A second connecting pipe 13 is fixedly connected to the first connecting pipe 12. One end of the second connecting pipe 13 is connected to the cavity. The connection end between the second connecting pipe 13 and the first connecting pipe 12 is located between the first valve 14 and the rotating ring 5. A second valve 15 is fixedly installed on the second connecting pipe 13. A first pressure relief head 16 is fixedly installed on each sealing ring 4. The first pressure relief head 16 is connected to the cavity. A first pressure relief valve 17 is fixedly installed on the first pressure relief head 16.

[0036] After the bellows is installed between the two sealing rings 4, the second valve 15 is opened and the first valve 14 is closed. The air supply assembly delivers gas into the cavity. The rubber ring 20 expands outward and fits tightly against the end of the bellows, which can significantly improve the sealing between the bellows and the rubber ring 20. Then, the bellows is submerged in water for air tightness testing. When the bellows is disassembled, the first pressure relief valve 17 is opened to allow the gas in the cavity to be discharged through the first pressure relief head 16. After the rubber ring 20 contracts, the rubber ring 20 and the end of the bellows become loose. Therefore, the installation and disassembly of the bellows are simpler.

[0037] The air supply assembly includes an air pump 9 and an air pipe 10. The air pump 9 is fixedly installed on the detection pool 1, and the air pipe 10 is fixedly connected to the air outlet end of the air pump 9. The two ends of the air pipe 10 are respectively fixedly connected to two rotating rings 5.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
