Description

Technical Field

[0001] This utility model relates to pipeline maintenance and repair technology, specifically an automatic water extraction and maintenance device for natural gas pipelines. Background Technology

[0002] During the transportation of natural gas, the water accumulation inside natural gas pipelines mainly comes from the water vapor contained in the natural gas itself (which remains after extraction and treatment) and the moisture left over from pipeline construction. If there is too much water accumulation, it can lead to risks such as corrosion, blockage, and freezing.

[0003] For example, publication number CN111299272A, publication date: 2020-06-19, discloses a natural gas pipeline cleaning device, including a steel pipe, a speed sensor, an electric drive head, a transmission rod, a turntable, a telescopic brush head, a convenient connection device, an upper connecting plate, an upper cup, a lower connecting plate, and a lower cup. The electric drive head and the speed sensor are built into the steel pipe, and the output end of the electric drive head is connected to the transmission rod. A groove is provided at the center of the upper surface of the upper connecting plate, and the turntable is set in the groove. The transmission rod passes through the groove and is connected to the turntable. The turntable is connected to multiple telescopic brush heads. When the flow velocity in the natural gas pipeline is lower than the predetermined movement speed, the speed sensor identifies this and automatically starts the electric drive head to rotate the turntable, allowing the telescopic steel brush head to extend to the inner diameter of the pipeline for deeper cleaning of the pipeline wall. When the cleaning device returns to normal speed, the brush head is retracted, which facilitates the reuse of the brush head and thus improves the cleaning efficiency of the cleaning device.

[0004] The shortcomings of existing technologies lie in the fact that commercially available pipeline cleaning tools are typically used to remove water accumulation in natural gas pipelines. The cleaning components of these tools consist of two rubber cups that fit tightly against the inner wall of the pipeline. The natural gas propels the rubber cups, carrying away the accumulated water and debris, which is then pumped out at a designated point. However, when excessive water and debris accumulate in the pipeline, the rubber cups near the bottom of the pipeline become severely damaged, reducing their sealing performance and potentially causing the pipeline cleaning tool to malfunction. This allows the accumulated water and debris to easily return to the path the cleaning tool has taken. Utility Model Content

[0005] The purpose of this invention is to provide an automatic water extraction and maintenance device for natural gas pipelines, in order to overcome the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic water extraction and maintenance device for natural gas pipelines includes a bearing seat with a flange and a lip cup installed on the outside of the flange. The lip cup has a lip opening on its side, and the lip opening divides the side of the lip cup to form a front lip and a rear lip.

[0008] The lip is provided with multiple guide members that rotate, and the guide members are provided with rollers.

[0009] As a further description of the above technical solution: it also includes a ring sleeve disposed on the outside of the flange and communicating with the opening on the flange.

[0010] As a further description of the above technical solution: the ring sleeve is fixedly connected to the leather cup.

[0011] As a further description of the above technical solution: the ring is specifically a steel alloy metal ring.

[0012] As a further description of the above technical solution: the roller is movable at the lip end.

[0013] As a further description of the above technical solution: a rotating shaft is fixedly installed on the guide member, and a threaded head is fixedly installed at the end of the rotating shaft.

[0014] As a further description of the above technical solution: the ring sleeve is provided with a threaded hole for the threaded head to be rotated and connected.

[0015] As a further description of the above technical solution: symmetrically distributed wing plates are fixedly installed on the rotating shaft, and a groove for embedding the wing plates is provided in the lip.

[0016] As a further description of the above technical solution: the leather bowl is provided with a bowl opening.

[0017] As a further description of the above technical solution: the wing plate slides in conjunction with the groove, so that multiple protrusions are formed in the bowl opening.

[0018] In the above technical solution, the automatic water extraction and maintenance device for natural gas pipelines provided by this utility model has the following beneficial effects: by opening a lip that is obliquely recessed towards its axis on the side of the diaphragm, the resulting front lip actively intercepts the sewage accumulated in front of the natural gas pipeline, and the space of the lip is used to block the sewage in front of the rear lip, making it difficult for sewage to seep from the rear lip to the rear diaphragm, thus improving the overall performance of the pig. By adjusting the guide component to make the rollers deflected in the direction of the side axis of the diaphragm, the multiple rollers on a single diaphragm roll in one of the spiral directions, which facilitates the spiral progression of the pig in the natural gas pipeline, realizes the change of the side direction of the diaphragm, and avoids the diaphragm side being always buried in sewage during operation, thereby protecting the seal of the pig.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 This utility model provides a technical solution, including the following embodiments:

[0028] Example 1

[0029] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment improves the structure of the rubber cup based on the original pig to enhance leak prevention and wear resistance, specifically by adding a lip 33 to the rubber cup 3. By creating a lip 33 that is obliquely recessed towards its axis on the side of the rubber cup 3, the resulting front lip 31 actively intercepts the sewage accumulated in front of the natural gas pipeline, and the space of the lip 33 is used to block the sewage in front of the rear lip 32, making it difficult for sewage to seep from the rear lip 32 into the rear rubber cup 3, thus improving the overall performance of the pig. Regularly inspecting the internal environment of the natural gas pipeline for contamination, and then pumping out the accumulated water at the location, the guide 4 is adjusted to deflect the roller 40 off the side axis of the rubber cup 3. This causes the multiple rollers 40 on a single rubber cup 3 to roll in one of the spiral directions, facilitating the spiral progression of the pig within the natural gas pipeline. This changes the direction of the side of the rubber cup 3, preventing a certain position on the side of the rubber cup 3 from being constantly submerged in sewage, thereby protecting the seal of the pig.

[0030] Specifically, multiple flanges 11 are welded to the bearing seat 1, which is existing technology and will not be described in detail here. The cup 3 is glued to the outside of the ring sleeve 2, so that the steel alloy ring sleeve 2 forms the skeleton of the cup 3 during operation.

[0031] Furthermore, the rubber roller 40 rotates in the U-shaped clip on the guide 4 via a bearing, and the side wall of the roller 40 is flush with the side of the cup 3, so as to ensure that the roller 40 always maintains a rolling connection with the inner wall of the natural gas pipeline.

[0032] Furthermore, a pipeline low-level position is set at a fixed location on the natural gas pipeline, and the low-level position is equipped with monitoring and location management equipment to open the interior of the natural gas pipeline. This equipment can be used to monitor the position of the pipeline pig equipped with signal receiving sensors, and can also open the pipeline and remove the pipeline pig for maintenance operations. This is existing technology and will not be elaborated here.

[0033] Example 2

[0034] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment details the structure of the cup 3 and its components. By rotating the roller 40, the threaded head 42 at the end of the shaft 41 is screwed into the threaded hole 21. This strengthens the connection between the shaft 41 and the ring sleeve 2 and the cup 3, and the tightening friction keeps the rotational position of the shaft 41 fixed, thereby fixing the angle of the adjusted roller 40 and ensuring stability during the spiral advance of the pig.

[0035] Secondly, during the rotation of the shaft 41, the skew angle of the roller 40 can be increased or decreased. The purpose is to adjust the pitch of the spiral advance of the pig, thereby adjusting the adjustment frequency of the cup 3 and accelerating the rotation speed of the cup 3 in advance when there is a lot of sewage, so as to speed up the position change.

[0036] Specifically, the rotating shaft 41 is distributed obliquely and radially along the bearing seat 1, and is used to provide support during the rolling process.

[0037] Example 3

[0038] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a way to clear the obstruction in the running direction of the bowl 30, preventing the accumulation of debris in front from forming clumps and affecting the normal operation of the pig. The wing plate 43 is driven to deflect and rotate within the groove 34 to change its position, causing the front lip 31 to bulge in response to the shape of the wing plate 43. This bulge is a protrusion 35, which agitates the sewage picked up in the bowl 30 as the pig spirals forward, keeping the debris in the sewage loose and preventing it from accumulating and causing blockages, thus ensuring smooth operation of the pig.

[0039] Specifically, the wing plate 43 is obtained by welding a triangular alloy metal plate onto the rotating shaft 41. The sum of the reaction force generated by the deformation of the rubber on the side wall of the groove 34 and the resistance of the sewage in the bowl 30 of the protrusion 35 is less than the friction force of the threaded head 42. The purpose is to ensure that the roller 40 is fixed at a predetermined angle so that the spiral progression of the pig remains stable.

[0040] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
