Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning, and particularly to a pipeline cleaning device. Background Art

[0002] The complex iron desulfurization process is mainly used for desulfurization of low-production and low-sulfur gas wells. During the process of the desulfurization solution absorbing hydrogen sulfide, hydrogen sulfide will directly react with the solution in the absorption tower to generate sulfur. The sulfur will move in the process pipeline along with the desulfurization solution, and sulfur deposition is likely to occur everywhere in the pipeline, and even cause blockage.

[0003] The desulfurization platform has limited means for the gradually increasing sulfur blockage and sulfur deposition in the process pipeline. Except for carrying out shutdown cleaning operations, high-pressure water guns are usually used for flushing to remove blockages. For example, a Chinese patent with the publication number CN107790443A discloses a pipeline high-pressure water cleaning device, which uses high-pressure water jets to strip and clean the dirt on the inner surface of the pipeline. However, the blockage removal ability of the high-pressure water gun is limited, and it can only clean the sulfur deposited in the short term, and the effect is not ideal for sulfur with a long deposition time. Summary of the Utility Model

[0004] The utility model provides a pipeline cleaning device, which can move in the pipeline and effectively remove the deposits on the inner wall of the pipeline.

[0005] The utility model provides a pipeline cleaning device, including a cylinder body, an end cover, a power mechanism, a transmission mechanism, a first Mecanum wheel, a second Mecanum wheel and a cutter head mechanism.

Detailed implementation manners

[0025] The present utility model will be further described below in conjunction with the accompanying drawings.

[0026] In order to solve the problem of pipeline blockage caused by the deposition of substances such as sulfur inside the pipeline, the prior art usually uses a high-pressure water gun to wash the deposits, and uses high-pressure water jets to peel and clean the dirt on the inner surface of the pipeline. However, the plugging removal ability of the high-pressure water gun is limited, and it can only clean the sulfur deposited in the short term, and the effect is not ideal for sulfur with a long deposition time.

[0027] In order to solve the above technical problems, as Figures 1 to 3 shown, the pipeline cleaning device of an embodiment of the present utility model includes a cylinder body 1, an end cover 2, a power mechanism 3, a transmission mechanism 4, a first Mecanum wheel 5, a second Mecanum wheel 6 and a cutter head mechanism 7. The end cover 2 is arranged at the first end of the cylinder body 1, the power mechanism 3 is arranged inside the cylinder body 1, the transmission mechanism 4 is connected to the power mechanism 3 and extends out from the second end of the cylinder body 1. The first Mecanum wheel 5, the second Mecanum wheel 6 and the cutter head mechanism 7 are all located outside the cylinder body 1 and are connected to the transmission mechanism 4, and the rotation directions of the first Mecanum wheel 5 and the second Mecanum wheel 6 are opposite.

[0028] The transmission mechanism 4 uses the power generated by the power mechanism 3 to drive the first Mecanum wheel 5, the second Mecanum wheel 6 and the cutter head mechanism 7 to rotate. Since the rotation directions of the first Mecanum wheel 5 and the second Mecanum wheel 6 are opposite, the rotational torques generated by the two cancel each other out, while the traction forces generated by the two are superimposed on each other, enabling the pipeline cleaning device to move inside the pipeline. During the movement of the pipeline cleaning device, the cutter head mechanism 7 directly scrapes the substances such as sediments on the inner wall of the pipeline, thereby effectively removing the sediments and the like.

[0029] As Figure 3 and Figure 4 shown, the transmission mechanism 4 includes a main shaft 41, a first gear disk 42, a second gear disk 43 and a connecting gear 44. The main shaft 41 is fixedly connected to the first gear disk 42. The second gear disk 43 is sleeved on the main shaft 41 and is disposed opposite to the first gear disk 42. The first Mecanum wheel 5 is fixedly connected to the main shaft 41. The connecting gear 44 is disposed between the first gear disk 42 and the second gear disk 43 and meshes with the first gear disk 42 and the second gear disk 43. The second Mecanum wheel 6 is sleeved on the main shaft 41 and is connected to the second gear disk 43. When the main shaft 41 rotates clockwise, the first Mecanum wheel 5 and the first gear disk 42 also rotate clockwise following the main shaft 41. Due to the existence of the connecting gear 44, the second gear disk 43 rotates counterclockwise at this time. Since the second Mecanum wheel 6 is connected to the second gear disk 43, it also rotates counterclockwise, thus achieving the coaxial reverse rotation effect of the first Mecanum wheel 5 and the second Mecanum wheel 6.

[0030] Furthermore, the transmission mechanism 4 further includes a bearing 45 and a plurality of connecting rods 46. The bearing 45 is sleeved on the main shaft 41. The second Mecanum wheel 6 is sleeved on the bearing 45. Both ends of the connecting rod 46 are respectively connected to the second gear disk 43 and the second Mecanum wheel 6. The rotation direction of the second Mecanum wheel 6 is opposite to the rotation direction of the main shaft 41. Therefore, a bearing 45 is provided on the main shaft 41 so that there is no interference between the main shaft 41 and the second Mecanum wheel 6. In addition to transmitting the torque of the second gear disk 43 to the second Mecanum wheel 6, the plurality of connecting rods 46 can also play a fixing role, making the second Mecanum wheel 6 more stable.

[0031] As Figure 5 shown, in order to facilitate the connection between the connecting rod 46 and the second Mecanum wheel 6, the second Mecanum wheel 6 is provided with a plurality of connection holes 61 for the connecting rod 46 to be inserted into.

[0032] As Figure 3 and Figure 4 shown, the transmission mechanism 4 further includes a fixing rod 47. Both ends of the fixing rod 47 are respectively connected to the connecting gear 44 and the cylinder body 1. The connecting gear 44 is rotatably disposed on the fixing rod 47. In order to keep the connecting gear 44 in a stable position, the connecting gear 44 is fixed to the cylinder body 1 through the fixing rod 47. AsFigure 1 As shown, a fixing hole 12 for installing the fixing rod 47 is provided on the cylinder body 1. The connecting gear 44 can only rotate on the fixing rod 47 and will not change its position due to the rotation of the first tooth disc 42 and the second tooth disc 43.

[0033] In this embodiment, the number of both the connecting gears 44 and the fixing rods 47 is three. The three connecting gears 44 are arranged at equal intervals between the first tooth disc 42 and the second tooth disc 43, making the power transmission between the first tooth disc 42 and the second tooth disc 43 more stable. The load on a single connecting gear 44 is also smaller, which is beneficial to improving the reliability of the transmission mechanism 4.

[0034] In this embodiment, the power mechanism 3 is a hydraulic motor. As Figure 2 shown, a liquid inlet 21 and a liquid outlet 22 are provided on the end cover 2. High-pressure liquid is connected to the liquid inlet 21 and the liquid outlet 22 through corresponding pipelines (not shown in the figure). It should be noted that the liquid inlet 21 and the liquid outlet 22 can be interchanged to achieve two different rotation directions of the power mechanism 3, so that the pipeline cleaning device can move forward and backward in the pipeline.

[0035] As Figure 1 and Figure 2 shown, a plurality of guide wheel sets 8 are further provided on the surface of the cylinder body 1. The guide wheel set 8 includes guide wheels 81 and brackets 82. The brackets 82 are arranged on the surface of the cylinder body 1, and the guide wheels 81 are arranged on the brackets 82. When the pipeline cleaning device moves inside the pipeline, the guide wheels 81 will roll on the inner wall of the pipeline to provide additional support. On the one hand, it can reduce the resistance when the pipeline cleaning device moves, and on the other hand, it can also play a guiding role to prevent the pipeline cleaning device from rotating during movement.

[0036] As Figure 1 shown, an installation groove 11 is further provided on the surface of the cylinder body 1. The bracket 82 is arranged in the installation groove 11, so that both sides of the bracket 82 can be supported by the groove walls of the installation groove 11, and the stability of the bracket 82 is higher.

[0037] As Figure 1 and Figure 6 shown, the cutter head mechanism 7 includes a disc body assembly 71 and a blade assembly 72. The disc body assembly 71 includes a connecting disc 711 and a plurality of scrapers 712 arranged at intervals along the circumference of the connecting disc 711. The blade assembly 72 is arranged on one side of the connecting disc 711. The blade assembly 72 includes at least two different lengths of blades 721. When the cutter head mechanism 7 rotates, the blades 721 will cut and break the deposits on the inner wall of the pipeline. Since the lengths of the individual blades 721 are not exactly the same, it can achieve a better cleaning effect on deposits of different thicknesses. The ends of the scrapers 712 will scrape the deposits on the inner wall of the pipeline. The blades 721 and the scrapers 712 cooperate with each other to jointly achieve effective cleaning of the inner wall of the pipeline.

[0038] Although the present utility model has been described with reference to the preferred embodiments, various modifications thereof can be made and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any manner. The present utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
