Description

Technical Field

[0001] The invention relates to the technical field of gas pipelines, and in particular to a PE gas pipeline capable of self-adapting to temperature changes. Background Art

[0002] Gas pipeline refers to the pipeline that transports natural gas from the mining site or processing plant to the urban gas distribution center or industrial enterprises and users, also known as the gas transmission pipeline. When the gas pipeline is transporting gas, due to the gaseous water mixed in the gas, it is transported through the pipeline for a long distance. Due to many factors such as temperature and pipe diameter, the gaseous water becomes liquid water. When the weather is extremely cold, even if the gas pipeline is wrapped with an antifreeze layer, the inside of the pipeline will freeze due to the low temperature, making it impossible to transport the gas inside, reducing the transportation efficiency of the pipeline. In order to protect the normal transportation of gas in the cold winter season, antifreeze gas pipeline protection devices are usually installed at the water accumulation location of the gas pipeline. The antifreeze gas pipeline protection device prevents the water from accumulating inside the gas pipeline and freezing, which affects the normal supply and use of gas.

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

[0004] However, the above-mentioned invention patent still has some shortcomings in actual use: 1. Heat is generated by the reaction of water and quicklime, which realizes the function of heat generation without using electricity. However, the reaction of water and quicklime will not only produce solid precipitation but also release a large amount of gas. The gas can easily cause the storage box to rupture, and the solid precipitation cannot be discharged; 2. The interior of the pipeline becomes a sliding outer wall, which will make the pipeline insufficiently airtight, and the entire mechanism is too complicated and lacks a linkage and coordination mechanism. The volume of the accumulated water solidifies into ice and increases, squeezing the first sealing plate to slide, thereby triggering the reaction of water and quicklime. The volume of the water condensed into ice increases, but whether the changing 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 with adaptive temperature changes is proposed to solve the above-mentioned problems. Summary of the invention

[0026] In this embodiment, the motor 19 starts to rotate, so that the motor 19 drives the transmission gear three 28 and the second threaded rod 11 to rotate through the transmission gear five 31 and the transmission chain two 30, so that the second threaded rod 11 drives the air-permeable scraper 3 to slide along the outer wall of the central heating chamber 4 to push the water out. At the same time, the transmission gear three 28 drives the transmission gear one 25 and the transmission gear two 26 to rotate through the transmission chain one 27, so that the first threaded rod 17 also rotates synchronously to push out the residual sediment in the central heating chamber 4 through the slag discharge plate 33.

[0027] Among them, the discharge mechanism 303 includes a material baffle plate 21, a first shaft rod 37, a half gear 24 and a limiting ring 43.

[0030] In this embodiment, the transmission gear 25 drives the half gear 24 to rotate, so that the half gear 24 drives the limiting ring 43 to rotate, so that the slide bar 42 slides along the slope of the limiting ring 43, and the slide bar 42 drives the drainage board 18 and the drainage board 23 to move through the connecting rod 3 41 and the slider 1 34, thereby opening the channel at the bottom of the conveying channel 7 to promote the discharge of the material.

[0032] In this embodiment, since the motor 19 needs to rotate a certain number of times, when the transmission gear 25 is not engaged with the half gear 24, the half gear 24 will be reversed a little by the pulling force of the spring 39, so that the transmission gear 25 always pushes the half gear 24 to reciprocate within a certain angle, so that the slider 34 slides back and forth within a certain range, but the discharge channel will not be closed. The slider 34 will drive the fixing frame 2 14 and the ice crusher 20 to crush the ice remaining in the water-absorbing sponge 10, so that it is discharged through the drainage board 2 23, and the water inside the pipeline body 1 will not pass through the water-absorbing sponge 10 during the discharge process, so as to prevent the water-absorbing sponge 10 from absorbing water and freezing again.

[0033] The specific working principle and method of use of the present invention are explained in detail below: when in use, the control valve 8 controls the water and quicklime in the insulated water tank 6 and the storage box 9 to flow into the central heating chamber 4 through the conveying channel 7, so that the central heating chamber 4 can dissipate heat inside the pipeline body 1, promote the melting of ice on the inner wall, and a large amount of gas generated is discharged through the conveying channel 7 and the air permeable net 12 to avoid damage to the inside of the pipeline. When the ice melts, the reacted precipitate remains inside the central heating chamber 4, and the melted water remains in the pipeline body 1.

[0034] The motor 19 starts to rotate, so that the motor 19 drives the transmission gear three 28 and the second threaded rod 11 to rotate through the transmission gear five 31 and the transmission chain two 30, so that the second threaded rod 11 drives the air-permeable scraper 3 to slide along the outer wall of the central heating chamber 4 to push the water out. At the same time, the transmission gear three 28 drives the transmission gear one 25 and the transmission gear two 26 to rotate through the transmission chain one 27, so that the first threaded rod 17 also rotates synchronously to push out the residual sediment in the central heating chamber 4 through the slag discharge plate 33.

[0035] At the same time, the transmission gear 25 drives the half gear 24 to rotate, so that the half gear 24 drives the limit ring 43 to rotate, so that the slide bar 42 slides along the slope of the limit ring 43, and the slide bar 42 drives the drainage board 18 and the drainage board 23 to move through the connecting rod 3 41 and the slider 1 34, thereby opening the channel at the bottom of the conveying channel 7 to promote the discharge of materials.

[0036] Since the motor 19 needs to rotate a certain number of circles, when the transmission gear 25 is not engaged with the half gear 24, the half gear 24 will be reversed a little by the pulling force of the spring 39, so that the transmission gear 25 always pushes the half gear 24 to reciprocate within a certain angle, so that the slider 34 slides back and forth within a certain range, but the discharge channel will not be closed. The slider 34 will drive the fixing frame 2 14 and the ice crusher 20 to crush the ice remaining in the water-absorbing sponge 10, so that it is discharged through the drainage board 23, and the water inside the pipeline body 1 will not pass through the water-absorbing sponge 10 during the discharge process, so as to prevent the water-absorbing sponge 10 from absorbing water and freezing again.

[0037] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.
