Description

Technical Field

[0001] The invention relates to the technical field of anti-corrosion pipelines, and in particular to a communication anti-corrosion pipeline based on multiple anti-corrosion devices. Background Art

[0002] Anti-corrosion pipeline refers to a pipeline system that has been specially treated or made of anti-corrosion materials. It is used to transport fluids or gases while being able to resist corrosion from the external environment or internal fluids, thereby extending the service life of the pipeline and ensuring the safety and reliability of the pipeline in harsh environments.

[0003] In the prior art, a Chinese patent with publication number "CN205039503U" discloses a communication anti-corrosion pipeline based on multiple anti-corrosion devices. By arranging an anti-corrosion lining on the inner wall of the pipeline and the flange end face, the structure can be prevented from directly contacting with corrosive gases such as moisture, which can well protect the buried communication pipeline and effectively improve the corrosion resistance of the communication cable. At the same time, a voltage stabilizing device is used to convert the external alternating current into low-voltage direct current, and the protective current is transmitted to the protected pipeline through an auxiliary anode conductive device, thereby effectively inhibiting corrosion. This has a good protective effect on the communication pipeline and solves the problem of troublesome maintenance and high maintenance cost of the existing communication pipeline after being corroded.

[0004] Existing anti-corrosion pipelines are usually produced and transported in sections of a certain length. During actual installation, the length of the pipeline is often not enough to cover the entire transportation route. In order to connect pipeline sections of different lengths into a complete pipeline system, docking is usually required. For example, in the above-mentioned solution, the anti-corrosion pipelines are docked using connecting flanges. However, when docking the connecting flanges, since the flange connection usually requires cutting and preparation at both ends of the pipeline, this may damage the original anti-corrosion layer of the pipeline. In particular, when welding flanges, the effect of the heat source may cause damage or unevenness of the anti-corrosion layer, causing corrosion at the pipeline joints. Summary of the invention

[0019] The present invention provides a communication anti-corrosion pipeline based on multiple anti-corrosion devices. Compared with the prior art, it has the following beneficial effects:

[0020] 1. The present invention drives the worm to rotate by rotating the driving rod, and the worm cooperates with the worm gear on the driving ring to make the driving ring rotate on the anti-corrosion ring. When the driving ring rotates, the connecting rod drives the rotating ring to rotate on the positioning ring, and the extrusion protrusion on the rotating ring rotates with the positioning ring as the center. The clamping plate is pressed by the extrusion protrusion to make the clamping plate fit the surface of the anti-corrosion pipe, and the installation between the anti-corrosion pipe and the anti-corrosion ring is completed by the clamping plate, which effectively ensures the high precision and stability of the docking of the two anti-corrosion pipes, and ensures the effectiveness and durability of the anti-corrosion protection;

By utilizing the contact between the extrusion cam and the extrusion plate, the extrusion plate will drive the piston on the extrusion rod to move in the extrusion cylinder. The gas in the extrusion cylinder will partially fill the extrusion airbag through the exhaust pipe and the outlet pipe. The firmness and sealing between the anti-corrosion pipeline and the connecting ring groove are enhanced by the expansion of the extrusion airbag, thereby ensuring the stability of the pipeline connection and improving the anti-corrosion effect.

[0022] 3. In the present invention, part of the gas discharged from the extrusion cylinder will enter the connecting pipe through the exhaust pipe, and the gas in the connecting pipe will enter the sealing airbag, which will expand in the annular shell. Since the annular shell is located at the connection between the anti-corrosion ring and the anti-corrosion pipeline, the expansion of the sealing airbag not only increases the contact pressure between the annular shell and the anti-corrosion pipeline and the anti-corrosion ring, but also forms a strong sealing effect through this expansion, which can effectively prevent gas leakage and erosion of the anti-corrosion pipeline by the external environment, and ensure the stability and anti-corrosion performance of the pipeline system;

[0023] 4. In the present invention, part of the gas in the extrusion cylinder will be discharged into the straight pipe through the exhaust pipe, the gas in the straight pipe will be discharged into the annular pipe, and the gas in the annular pipe will be discharged into the fitting airbag through the connecting pipe. The fitting airbag will expand in the mounting groove. Since the mounting groove is arranged on the clamping plate, the expanded airbag will fit on the anti-corrosion pipe. The clamping effect of the clamping plate on the anti-corrosion pipe is enhanced by the fitting airbag, which effectively ensures that the anti-corrosion pipe remains stable and effectively prevents loosening or leakage between the anti-corrosion pipe and the anti-corrosion ring.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-11 The present invention is a communication anti-corrosion pipeline 1 based on multiple anti-corrosion devices, including an anti-corrosion pipeline 1 and an anti-corrosion base plate 2. The anti-corrosion pipeline 1 includes an anti-corrosion coating 101, an anti-corrosion layer 102, an anti-corrosion auxiliary layer 103, a reinforcement layer 104 and an outer protective layer 105 arranged from the inside to the outside.

[0041] In this article, the anti-corrosion coating 101 is the coating closest to the inner wall of the pipeline, which is usually used to prevent the conveying medium from directly contacting the pipeline material and reducing corrosion. The material used is polyurethane. The anti-corrosion layer 102 is the main anti-corrosion protective layer of the pipeline. The material used is polypropylene. This layer is mainly used to prevent the external environment (such as soil, moisture, and chemicals in the air) from eroding the pipeline. The anti-corrosion auxiliary layer 103 is usually used as an additional protective layer to enhance the corrosion resistance of the pipeline. The reinforcement layer 104 is used to enhance the mechanical strength and compressive resistance of the pipeline, especially in an environment with large external pressure or external physical impact. It is usually composed of metal belts, wire mesh or fiber reinforced materials. The outer protective layer 105 is the outermost layer of the pipeline. The material used is polyethylene. Its main function is to provide mechanical protection against the environment to prevent the pipeline from being damaged during transportation, installation, and use. At the same time, it can also provide protection for the pipeline against corrosive substances in the soil and air.

[0042] The anti-corrosion bottom plate 2 is provided with a connecting assembly and an anti-corrosion assembly, and the anti-corrosion ability of the connection between the two anti-corrosion pipes 1 is improved by the connecting assembly and the anti-corrosion assembly. The connecting assembly includes a bracket plate 5 and a clamping plate 6. The bracket plate 5 is fixedly installed with symmetrically arranged side plates 7.

[0043] A plurality of lifting cavities 17 are provided inside the positioning ring 13, and a lifting block 18 is slidably connected inside the lifting cavity 17. A lifting rod 19 is fixedly installed on the lifting block 18. One end of the lifting rod 19 away from the lifting block 18 extends to the outside of the lifting cavity 17 and is fixedly installed with the clamping plate 6. A first spring 20 is fixedly installed on the lifting block 18, and one end of the first spring 20 away from the lifting block 18 is fixedly connected to the inside of the lifting cavity 17. The position of the first spring 20 is on the outside of the lifting rod 19, and the lower end surface of the extrusion protrusion 15 contacts and slides with the upper end surface of the clamping plate 6, wherein the lower end surface of the extrusion protrusion 15 and the upper end surface of the clamping plate 6 are set as arc surfaces, so that the extrusion protrusion 15 can squeeze the clamping plate 6 when rotating, and at the same time, the contact surface friction between the two is small, avoiding large wear between the extrusion cam 25 and the clamping plate 6, wherein the number of the clamping plates 6 is at least four, ensuring that the clamping plate 6 clamps and positions the anti-corrosion pipeline 1.

[0044] In this article, the worm 9 is driven to rotate by rotating the driving rod 8, and the worm 9 cooperates with the worm gear 11 on the driving ring 10 to make the driving ring 10 rotate on the anti-corrosion ring 3. When the driving ring 10 rotates, the rotating ring 14 is driven to rotate on the positioning ring 13 through the connecting rod 16. The extrusion protrusion 15 on the rotating ring 14 will rotate around the positioning ring 13. The extrusion protrusion 15 squeezes the clamping plate 6 to make the clamping plate 6 fit the surface of the anti-corrosion pipe 1. The clamping plate 6 is used to complete the installation between the anti-corrosion pipe 1 and the anti-corrosion ring 3, effectively ensuring the high precision and stability of the docking of the two anti-corrosion pipes 1, and ensuring the effectiveness and durability of the anti-corrosion protection.

[0045] The anti-corrosion component includes a positioning plate 21 fixedly mounted on the side plate 7, an extrusion cylinder 22 is fixedly mounted on the positioning plate 21, an extrusion rod 23 is slidably connected to the extrusion cylinder 22, an extrusion plate 24 is fixedly mounted on the end of the extrusion rod 23 away from the extrusion cylinder 22, an extrusion cam 25 is fixedly mounted on the driving rod 8 and on one side of the worm 9, the extrusion cam 25 is in contact with the extrusion plate 24, a limiting rod 44 is fixedly mounted on the lower end surface of the extrusion plate 24, an end of the limiting rod 44 away from the extrusion plate 24 passes through the positioning plate 21, and a limiting plate 45 is fixedly mounted, a second spring 46 is fixedly mounted on the limiting plate 45, and an end of the second spring 46 away from the limiting plate 45 is fixedly connected to the positioning plate On the positioning plate 21, the position of the second spring 46 is on the outside of the limiting rod 44, the air outlet of the extrusion cylinder 22 is fixedly connected to the exhaust pipe 26, the end of the exhaust pipe 26 away from the extrusion cylinder 22 is fixedly connected to the air outlet pipe 27, the end of the air outlet pipe 27 away from the exhaust pipe 26 is fixedly connected to the extrusion airbag 28, and the inner side surface of the connecting ring groove 4 is provided with a receiving groove 29, the extrusion airbag 28 is fixedly installed inside the receiving groove 29, wherein the end of the extrusion rod 23 away from the extrusion plate 24 is fixedly installed with a piston, because the piston is a technology well known to people in this field, it is not described in detail here, wherein the end of the air outlet pipe 27 away from the exhaust pipe 26 extends to the inside of the receiving groove 29.

[0046] In this article, when the driving rod 8 rotates, the extrusion cam 25 will be synchronously driven to rotate around the driving rod 8. By utilizing the contact between the extrusion cam 25 and the extrusion plate 24, the extrusion plate 24 will drive the piston on the extrusion rod 23 to move in the extrusion cylinder 22. The gas in the extrusion cylinder 22 will partially fill the extrusion airbag 28 through the exhaust pipe 26 and the outlet pipe 27. The expansion of the extrusion airbag 28 can enhance the firmness and sealing between the anti-corrosion pipeline 1 and the connecting ring groove 4, thereby ensuring the stability of the pipeline connection and improving the anti-corrosion effect.

[0047] An annular shell 30 is fixedly installed on the side end face of the anti-corrosion ring 3, a sealing airbag 31 is fixedly installed inside the annular shell 30, a connecting pipe 32 is fixedly connected to the sealing airbag 31, and one end of the connecting pipe 32 away from the sealing airbag 31 passes through the annular shell 30 and is fixedly connected to the exhaust pipe 26.

[0048] In this article, part of the gas discharged from the extrusion cylinder 22 will enter the connecting pipe 32 through the exhaust pipe 26, and the gas in the connecting pipe 32 will enter the sealing airbag 31, and the sealing airbag 31 will expand in the annular shell 30. Since the annular shell 30 is located at the connection between the anti-corrosion ring 3 and the anti-corrosion pipeline 1, the expansion of the sealing airbag 31 not only increases the contact pressure between the annular shell 30 and the anti-corrosion pipeline 1 and the anti-corrosion ring 3, but also forms a solid sealing effect through this expansion, which can effectively prevent gas leakage and external environment erosion of the pipeline, thereby ensuring the stability and anti-corrosion performance of the pipeline system.

[0049] An installation groove 33 is provided on the inner side surface of the clamping plate 6, and a fitting airbag 34 is fixedly installed inside the installation groove 33. A straight tube 35 is fixedly connected to the fitting airbag 34, and an end of the straight tube 35 away from the fitting airbag 34 is fixedly connected to an annular tube 36, and a connecting tube 37 is fixedly connected to the annular tube 36. The connecting tube 37 is fixedly connected to the connecting tube 32, wherein the annular tube 36 is located on the outside of the anti-corrosion pipe 1, ensuring that the end of the anti-corrosion pipe 1 can be installed in the connecting ring groove 4 of the anti-corrosion ring 3.

[0050] In this article, part of the gas in the extrusion cylinder 22 will be discharged into the straight pipe 35 through the exhaust pipe 26, the gas in the straight pipe 35 will be discharged into the annular pipe 36, and the gas in the annular pipe 36 will be discharged into the fitting airbag 34 through the connecting pipe 37. The fitting airbag 34 will expand in the mounting groove 33. Since the mounting groove 33 is arranged on the clamping plate 6, the expanded airbag will fit on the anti-corrosion pipe 1. The clamping effect of the clamping plate 6 on the anti-corrosion pipe 1 is enhanced by the fitting airbag 34, which effectively ensures that the anti-corrosion pipe 1 remains stable and effectively prevents loosening or leakage between the anti-corrosion pipe 1 and the anti-corrosion ring 3.

[0051] The adjusting assembly includes a driving rotating plate 38 and a gear 39 fixedly mounted on the driving rod 8, the side end surface of the side plate 7 is rotatably connected with a rotating shaft 40, an arc-shaped stopper 41 is fixedly mounted on the rotating shaft 40, a torsion spring 42 is fixedly connected to the arc-shaped stopper 41, the other end of the torsion spring 42 is fixedly connected to the side plate 7, and a positioning block 43 is fixedly mounted on the side plate 7 and at one end of the rotating shaft 40. The positioning block 43 cooperates with the arc-shaped stopper 41 to avoid reversal of the driving rod 8, wherein the position of the driving rotating plate 38 is on the outside of the gear 39. When the driving rod 8 restores the driving rod 8 to its original position after rotation, since the arc-shaped stopper 41 uses the torsion spring 42 to restore its original state, personnel can manually rotate the arc-shaped stopper 41 so that the arc-shaped stopper 41 will not block the reversal of the gear 39.

[0052] In this article, the driving turn plate 38 is used to facilitate personnel to manually drive the driving rod 8 to rotate. When the driving rod 8 rotates, the driving gear 39 will rotate synchronously. Through the cooperation of the gear 39 and the arc-shaped stopper 41, when the gear 39 rotates around the driving rod 8, the cooperation between the arc-shaped stopper 41 and the gear 39 and the limiting of the positioning block 43 are used to effectively ensure that the driving rod 8 will not reverse after the rotation angle.

[0053] Working principle:

[0054] When in use, the ends of the two anti-corrosion pipes 1 to be butted are respectively inserted into the connecting ring grooves 4 of the anti-corrosion rings 3, and then the driving rotating plate 38 is used to drive the driving rod 8 to rotate, and the driving rod 8 is used to drive the worm 9 to rotate, and the worm 9 is used to cooperate with the worm gear 11 on the driving ring 10, so that the driving ring 10 rotates on the anti-corrosion ring 3. When the driving ring 10 rotates, the connecting rod 16 drives the rotating ring 14 to rotate on the positioning ring 13, and the extrusion protrusion 15 on the rotating ring 14 rotates with the positioning ring 13 as the center. The clamping plate 6 is pressed by the extrusion protrusion 15 to make the clamping plate 6 fit the surface of the anti-corrosion pipe 1, and the installation between the anti-corrosion pipe 1 and the anti-corrosion ring 3 is completed by the clamping plate 6;

[0055] When the driving rod 8 rotates, the extrusion cam 25 will be synchronously driven to rotate around the driving rod 8. By utilizing the contact between the extrusion cam 25 and the extrusion plate 24, the extrusion plate 24 will drive the piston on the extrusion rod 23 to move in the extrusion cylinder 22. The gas in the extrusion cylinder 22 will partially fill the extrusion airbag 28 through the exhaust pipe 26 and the outlet pipe 27. The expansion of the extrusion airbag 28 will enhance the firmness and sealing performance between the anti-corrosion pipeline 1 and the connecting ring groove 4.

[0056] Part of the gas discharged from the extrusion cylinder 22 will enter the connecting pipe 32 through the exhaust pipe 26, and the gas in the connecting pipe 32 will enter the sealing airbag 31, and the sealing airbag 31 will expand in the annular shell 30. Since the annular shell 30 is located at the connection between the anti-corrosion ring 3 and the anti-corrosion pipeline 1, the expansion of the sealing airbag 31 not only increases the contact pressure between the annular shell 30 and the anti-corrosion pipeline 1, and the anti-corrosion ring 3, but also forms a strong sealing effect through this expansion.

[0057] Part of the gas in the extrusion cylinder 22 will be discharged into the straight pipe 35 through the exhaust pipe 26, the gas in the straight pipe 35 will be discharged into the annular pipe 36, and the gas in the annular pipe 36 will be discharged into the fitting airbag 34 through the connecting pipe 37. The fitting airbag 34 will expand in the mounting groove 33. Since the mounting groove 33 is arranged on the clamping plate 6, the expanded airbag will fit on the anti-corrosion pipe 1, and the clamping effect of the clamping plate 6 on the anti-corrosion pipe 1 will be enhanced by the fitting airbag 34.

[0058] When the driving rod 8 rotates, the driving gear 39 will rotate synchronously. Through the cooperation between the gear 39 and the arc-shaped stopper 41, when the gear 39 rotates around the driving rod 8, the cooperation between the arc-shaped stopper 41 and the gear 39 and the limiting of the positioning block 43 can effectively ensure that the driving rod 8 will not reverse after the rotation angle.

[0059] When the squeezing cam 25 is lowered to squeeze the squeezing plate 24, the elastic force of the second spring 46 is used to restore the squeezing plate 24 to its original position, the piston in the squeezing cylinder 22 moves upward, and the gas in the squeezing airbag 28, the sealing airbag 31 and the laminating airbag 34 is pumped back into the squeezing cylinder 22.

[0060] A valve may be provided on the exhaust pipe 26 to effectively prevent the gas in the squeeze airbag 28, the sealing airbag 31 and the fitting airbag 34 from flowing back. Since the valve is a technology well known to those skilled in the art, it will not be described in detail here.

[0061] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
