[0030] The present invention will be further described in detail below with reference to embodiments:

[0031] Example 1

[0032] like Figure 1-5As shown, this utility model provides a gas pipeline for preventing leakage, including a gas pipeline body 1, a shock-absorbing unit 2 on the outer side of the gas pipeline body 1, a maintenance unit 3 at one end of the shock-absorbing unit 2, a pressure relief unit 4 on the top surface of the maintenance unit 3, and a warning unit 5 inside the pressure relief unit 4. The warning unit 5 includes a rotating rod 51, which is located inside the pressure relief unit 4. A fan blade 52 is fixedly connected to the surface of the rotating rod 51, a spring 43 is fixedly connected to one side of the rotating rod 51, a striking ball 54 is fixedly connected to one end of the spring 43, and a sounding bell 55 is located on the bottom side of the striking ball 54. The sounding bell 55 is located on the top surface of the pressure relief unit 4. The pressure relief unit 4 includes a pressure relief pipe 41, which is located on the fixed top surface of the sealing cover 32. Vent holes 42 are evenly distributed inside the pressure relief pipe 41, and the inside of the pressure relief pipe 41 is rotatably connected to the surface of the rotating rod 51. A T-shaped rod 43 is installed inside the pressure relief pipe 41. A spring 44 is sleeved on the outside of the T-shaped rod 43. One end of the spring 44 is fixedly connected to the top surface inside the pressure relief pipe 41, and the other end of the spring 44 is fixedly connected to a sealing plate 45. When a leak occurs at the interface of the gas pipeline body 1, the leaked gas enters the interior of the pressure relief pipe 41 through the through hole 33. At the same time, the pressure pushes the T-shaped rod 43 on one side of the sealing plate 45 to slide inside the pressure relief pipe 41, and at the same time, it drives the spring 44 to compress. Simultaneously, the sealing plate 45 moves to the top side of the vent hole 42, and the gas is discharged from the interior of the pressure relief pipe 41. At the same time, the gas acts on the inside of the fan blade 52, pushing the rotating rod 51 to rotate. At the same time, the striking ball 54 at one end of the spring 43 strikes the sounding bell 55, and the sounding bell 55 produces a sound, thereby alerting the workers and facilitating quick repairs.

[0033] Example 2

[0034] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the shock absorption unit 2 includes an anti-slip block 21, which is disposed on the outside of the gas pipeline body 1. A bonding block 22 is fixedly connected to one side of the anti-slip block 21, and a hydraulic shock absorption rod 23 is fixedly connected to one side of the bonding block 22. A spring 24 is sleeved on the outside of the hydraulic shock absorption rod 23. One end of the spring 24 is fixedly connected to one side of the bonding block 22, and one end of the spring 24 is fixedly connected to an outer tube 25. The inner side of the outer tube 25 is fixedly connected to one end of the hydraulic shock absorption rod 23. During daily use, when an external impact occurs inside the outer tube 25, the outer tube 25 blocks the impacting object, thereby protecting the gas pipeline body 1. At the same time, the impact force generated is buffered by the action of the hydraulic shock absorption rod 23 and the spring 24. Meanwhile, the anti-slip block 21 further prevents the gas pipeline body 1 from shifting and sliding.

[0035] Example 3

[0036] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the maintenance unit 3 includes a housing 31, which is fixedly connected to one end of the outer pipe 25. A sealing cover 32 is provided on the top surface of the housing 31, and a through hole 33 is opened on the top surface of the sealing cover 32. A limit box 34 is fixedly connected to one side of the housing 31. A fixing block 35 is slidably connected inside the limit box 34. A second spring 36 is fixedly connected to one side of the fixing block 35. One end of the second spring 36 is fixedly connected inside the limit box 34. Pulling the fixing block 35 causes the second spring 36 to be compressed, and the fixing block 35 slides out from inside the sealing cover 32. The sealing cover 32 can then be removed, and workers can inspect the gas pipeline body 1 interface inside the housing 31.

[0037] The working principle of this gas pipeline designed to prevent leaks will be explained in detail below.

[0038] like Figure 1-5 As shown, during daily use, when an external impact occurs inside the outer pipe 25, the outer pipe 25 blocks the impacting object, thus protecting the gas pipeline body 1. Simultaneously, the impact force is buffered by the hydraulic shock absorber 23 and spring 24. The anti-slip block 21 further prevents displacement and slippage of the gas pipeline body 1. At the same time, pulling the fixing block 35 compresses the spring 36, causing the fixing block 35 to slide out from inside the sealing cover 32, allowing the sealing cover 32 to be removed. Workers can then inspect the gas pipeline body 1 interface inside the housing 31. When a leak occurs at the interface of the gas pipeline body 1, the leaking gas enters the interior of the pressure relief pipe 41 through the through hole 33. At the same time, the pressure pushes the T-shaped rod 43 on one side of the sealing plate 45 to slide inside the pressure relief pipe 41, and at the same time drives the spring 3 44 to compress. Simultaneously, the sealing plate 45 moves to the top side of the vent hole 42, and the gas is discharged from the interior of the pressure relief pipe 41. At the same time, the gas acts on the inside of the fan blade 52, pushing the rotating rod 51 to rotate. Simultaneously, the striking ball 54 at one end of the spring 4 53 strikes the sounding bell 55, and the sounding bell 55 produces a sound, thereby alerting the workers and facilitating quick repairs.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
