Description

Technical Field

[0001] The present invention relates to the technical field of gas pipelines, and in particular to a PE gas pipeline adaptable to temperature changes. Background Technique

[0002] A gas pipeline refers to a pipeline that transports natural gas from the extraction site or treatment plant to the urban gas distribution center or industrial enterprises and users, also known as a gas transmission pipeline. When transporting gas, since gaseous water is mixed inside the gas, after long-distance transportation through the pipeline, due to various reasons such as temperature and pipe diameter, the gaseous water forms liquid water. When the weather is extremely cold, even if the gas pipeline is wrapped with an anti-freezing layer, the pipeline will freeze inside due to the low temperature, making the internal gas unable to be transported, reducing the transportation efficiency of the pipeline. To protect the normal transportation of gas in the cold winter season, an anti-freezing gas pipeline protection device is usually installed at the water accumulation position of the gas pipeline to prevent the internal water of the gas pipeline from freezing and affecting the normal supply and use of gas.

[0003] The patent with the publication number: CN117469505A discloses an anti-freezing gas pipeline protection device for low-temperature environments, including a gas pipeline. One end of the gas pipeline is fixedly provided with a telescopic mechanism connected to it, and several heating components are arranged on the telescopic mechanism; the telescopic mechanism is connected to the heating components through a linkage component; the telescopic mechanism can increase the internal space to adapt to the volume change of the accumulated water solidifying into ice; the heating components can heat the pipeline without using electricity.

[0004] However, the above-mentioned invention patent still has some deficiencies in actual use: 1. By reacting water with quicklime to generate heat, the function of generating heat without using electricity is realized, but the reaction between water and quicklime will not only produce solid precipitation but also release a large amount of gas, and the gas is extremely likely to cause the storage tank to burst, and the solid precipitation cannot be discharged; 2. The inner wall of the pipeline becomes a slidable outer wall, which will result in insufficient pipeline tightness, and the entire mechanism is too complex, lacking a linkage cooperation mechanism. Through the volume increase of the accumulated water solidifying into ice, the first sealing plate is extruded to slide, thereby triggering the reaction between water and quicklime. The volume of water condensing into ice increases, but whether the changed displacement can squeeze out enough water to melt the ice inside the pipeline. If you want to achieve the effect of squeezing the first sealing plate to slide, the entire pipeline needs to be filled with ice, which is very unreasonable. Therefore, a PE gas pipeline adaptable to temperature changes is proposed to solve the above-mentioned problems. Summary of the Invention

[0039] Among them, the ice melting mechanism 101 includes a heat preservation water tank 6, a storage tank 9 and two control valves 8.

The heat preservation water tank 6 and the storage tank 9 are both connected to the conveying channel 7. The two control valves 8 are respectively fixedly connected to the heat preservation water tank 6 and the storage tank 9.

[0040] In this implementation scheme, during use, the control valve 8 controls the water and quicklime in the heat preservation water tank 6 and the storage tank 9 to flow into the central heating cavity 4 through the conveying channel 7, so that the central heating cavity 4 can dissipate heat inside the pipe body 1, promote the melting of the ice on the inner wall, and a large amount of generated gas is discharged through the conveying channel 7 and the ventilation net 12, avoiding damage to the inside of the pipe. When the ice melts, there are reaction precipitates left inside the central heating cavity 4, and the melted water remains in the pipe body 1.

[0041] Among them, the water slag co-discharge mechanism 202 includes a motor 19, a fifth transmission gear 31, a second transmission chain 30, a fourth transmission gear 29 and a third transmission gear 28.

The slag discharging plate 33 is slidably connected to the first threaded rod 17 through the two limit sliding rails 32.

[0043] Among them, the slag and water discharging mechanism 202 further includes a first transmission gear 25, a first transmission chain 27 and a second transmission gear 26. The first transmission gear 25 and the second transmission gear 26 are fixedly connected by a provided shaft rod. The second transmission gear 26 is rotatably connected to the conveying channel 7 by a provided shaft rod. The first threaded rod 17 is fixedly connected to the second transmission gear 26. The first transmission chain 27 is sleeved on the outer walls of the second transmission gear 26 and the third transmission gear 28.

[0044] In this implementation plan, the motor 19 starts to rotate, so that the motor 19 drives the third transmission gear 28 and the second threaded rod 11 to rotate through the fifth transmission gear 31 and the second transmission chain 30, so that the second threaded rod 11 drives the breathable scraper 3 to slide along the outer wall of the central heating chamber 4 to push out the water. At the same time, the third transmission gear 28 drives the first transmission gear 25 and the second transmission gear 26 to rotate through the first transmission chain 27, so that the first threaded rod 17 also rotates synchronously to push out the sediment remaining in the central heating chamber 4 through the slag discharging plate 33.

[0045] Among them, the discharging mechanism 303 includes a baffle plate 21, a first shaft rod 37, a half gear 24 and a limit ring 43. The baffle plate 21 is fixedly connected to the first shaft rod 37. The first shaft rod 37 is fixedly connected to the half gear 24. The outer wall of the first shaft rod 37 is rotatably connected to the conveying channel 7. The limit ring 43 is fixedly connected to the half gear 24. The outer wall of the half gear 24 meshes with the first transmission gear 25.

[0046] Among them, the discharging mechanism 303 further includes a first sliding rod 42, a third connecting rod 41, a first slider 34, a fixed frame 35, a first fixed rod 38, a spring 39 and a second fixed rod 40. The first sliding rod 42 is slidably connected to the limit ring 43. The third connecting rod 41 is rotatably connected to the first sliding rod 42. The third connecting rod 41 is fixedly connected to the first slider 34. The first slider 34 is fixedly connected to the first fixed rod 38. The second fixed rod 40 is fixedly connected to the conveying channel 7. The spring 39 is fixedly connected between the first fixed rod 38 and the second fixed rod 40. The fixed frame 35 is fixedly connected to the conveying channel 7. The first slider 34 is slidably connected to the fixed frame 35.

[0047] Among them, the discharge mechanism 303 further includes a first drainage plate 18, a second drainage plate 23, and a first connecting rod 22. Both the first drainage plate 18 and the second drainage plate 23 are slidably connected to the conveying channel 7, and the first connecting rod 22 is fixedly connected between the first drainage plate 18 and the second drainage plate 23.

[0048] In this embodiment, the driving gear one 25 drives the half gear 24 to rotate, so that the half gear 24 drives the limiting ring 43 to rotate, causing the first sliding rod 42 to slide along the slope of the limiting ring 43. The first sliding rod 42 drives the first drainage plate 18 and the second drainage plate 23 to move through the third connecting rod 41 and the first slider 34, thereby opening the channel at the bottom of the conveying channel 7 and promoting the discharge of substances.

[0049] Among them, drainage blocks 15 are fixedly connected to the outer walls on both sides of the conveying channel 7. The sponge ice crushing mechanism 404 includes a connecting block 36, a second fixing frame 14, and a number of ice crushing columns 20. The connecting block 36 is fixedly connected to the first slider 34, the connecting block 36 is fixedly connected to the second fixing frame 14, and a number of ice crushing columns 20 are fixedly connected to the second fixing frame 14.

[0050] In this embodiment, since the motor 19 needs to rotate a certain number of turns, when the driving gear one 25 is not engaged with the half gear 24, the half gear 24 will be reversely rotated a little by the pulling force of the spring 39, so that the driving gear one 25 always pushes the half gear 24 to reciprocally rotate within a certain angle, causing the first slider 34 to reciprocally slide within a certain range, but not closing the discharge channel. The first slider 34 will drive the second fixing frame 14 and the ice crushing columns 20 to crush the remaining ice on the water-absorbing sponge 10, which is then discharged through the second drainage plate 23. Moreover, the water inside the pipe body 1 will not pass through the water-absorbing sponge 10 during the drainage process, preventing the water-absorbing sponge 10 from absorbing water and freezing again.

[0051] The following is a detailed explanation of the specific working principle and usage method of the present invention: During use, the control valve 8 controls the water and quicklime in the heat preservation water tank 6 and the storage tank 9 to flow into the central heating chamber 4 through the conveying channel 7, enabling the central heating chamber 4 to dissipate heat inside the pipe body 1, promoting the melting of the ice on the inner wall. A large amount of gas generated is discharged through the conveying channel 7 and the ventilation net 12, preventing damage to the inside of the pipe. When the ice melts, there are reaction residues left inside the central heating chamber 4, and melted water remains inside the pipe body 1.

[0052] The motor 19 starts to rotate, causing the motor 19 to drive the driving gear three 28 and the second threaded rod 11 to rotate through the driving gear five 31 and the second transmission chain 30, so that the second threaded rod 11 drives the ventilation scraper 3 to slide along the outer wall of the central heating chamber 4 to push out the water. At the same time, the driving gear three 28 drives the driving gear one 25 and the driving gear two 26 to rotate through the first transmission chain 27, causing the first threaded rod 17 to also rotate synchronously to push out the remaining sediment inside the central heating chamber 4 through the slag discharge plate 33.

[0053] Meanwhile, the driving gear 1 25 drives the half gear 24 to rotate, causing the half gear 24 to drive the limit ring 43 to rotate, so that the first slide bar 42 slides along the slope of the limit ring 43. The first slide bar 42 drives the first drainage plate 18 and the second drainage plate 23 to move through the third connecting rod 41 and the first slider 34, thereby opening the channel at the bottom of the conveying channel 7 and promoting the discharge of substances.

[0054] Since the motor 19 needs to rotate a certain number of turns, when the driving gear 1 25 is not engaged with the half gear 24, the half gear 24 will be pulled back a little by the spring 39, so that the driving gear 1 25 always pushes the half gear 24 to rotate reciprocally within a certain angle, so that the first slider 34 slides reciprocally within a certain range, but does not close the discharge channel. The first slider 34 will drive the second fixing frame 14 and the ice crushing column 20 to crush the remaining ice on the water absorbing sponge 10, which is then discharged through the second drainage plate 23. Moreover, the water inside the pipe body 1 will not pass through the water absorbing sponge 10 during the drainage process, avoiding the water absorbing sponge 10 from absorbing water and freezing again.

[0055] Further explanation, the above fixed connection, unless otherwise clearly specified and limited, should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
