Description

Technical Field

[0001] This utility model relates to the field of industrial pipeline transportation technology, and in particular to a natural gas pipeline pigging device. Background Technology

[0002] Industrial pipeline transportation is a transmission method used in the industrial field. It uses a series of pipelines of different materials, specifications and functions to safely, efficiently and continuously transport various fluid media, such as natural gas and steam; liquids such as petroleum, chemical raw materials and water; and even some fluids with special properties, such as corrosive liquids and high-viscosity fluids, from the production source or storage location to various process links or end users, so as to meet the material transportation needs of industrial production processes and ensure the normal operation of industrial production systems.

[0003] A natural gas pipeline cleaning tool is a specialized tool propelled by gas, liquid, or pipeline transport medium to clean natural gas pipelines. Made of rubber, plastic, or other wear-resistant materials, it is designed to match the pipeline diameter. The outer edge of the cleaning tool's cup provides an elastic seal with the inner wall of the pipeline. Utilizing the pressure difference generated by the transported medium, it travels along the pipeline, relying on its own or its attached tools' scraping and flushing action to remove accumulated water, light oil, corrosive substances such as methane hydrate, and impurities, thus completing the task of cleaning complex pipelines. However, natural gas transmission networks are complex and diverse, and different pipelines have different uses. In actual natural gas pipeline cleaning operations, the usual method is to accurately match the correct size cleaning tool to the specific pipeline. However, different sized cleaning tools have different operational requirements, increasing operational complexity and training costs. Furthermore, in complex pipeline systems, different sized cleaning tools need to be used multiple times, which is time-consuming, reduces cleaning efficiency, and interferes with normal pipeline operation. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a natural gas pipeline cleaning tool, which aims to improve the existing technology where different pipelines have different uses, and in actual natural gas pipeline cleaning operations, it is necessary to accurately match the correct size of the cleaning tool according to different pipelines. However, the operation requirements of different sized cleaning tools are different, which increases the complexity of operation and training costs.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a natural gas pipeline cleaning device, including a frame, a knob in the middle of the frame, a metal gear 1 fixedly connected to the rear side of the knob, a metal gear 2 rotatably connected to the inner side of the frame, the metal gear 1 and the metal gear 2 meshing together, a threaded rod fixedly connected to the rear side of the metal gear 2, a movable disk threadedly connected to the outer side of the threaded rod, multiple deflection plates equidistantly arranged on the outer side of the movable disk, a cleaning plate fixedly connected to the top of the deflection plates, a rotating disk slidably connected to the rear side of the cleaning plate, a motor 1 fixedly connected to the rear side of the rotating disk, and a flushing mechanism provided on the front side of the frame, the flushing mechanism being used to flush the surface of the pipeline.

A sliding ring is fixedly connected to the outer side of the rack, and sliding strips are fixedly connected to both the left and right ends of the sliding ring. A rinsing plate is connected to the outer side of the sliding ring, and a water storage tank is connected to the top of the rinsing plate.

[0008] As a further description of the above technical solution:

[0009] Multiple sliding wheels are equidistantly installed on the outer side of the frame, and springs are provided on the outer side of each sliding wheel.

[0010] As a further description of the above technical solution:

[0011] A handle is installed on the front side of the frame, and a screw is threaded to the left and right ends of the handle. The handle is threaded to the frame through the screw.

[0012] As a further description of the above technical solution:

[0013] The top and front and rear ends of the water storage tank are fixedly connected with reinforcing plates.

[0014] As a further description of the above technical solution:

[0015] The knob is rotatably connected to a steering knuckle one, and a steering knuckle two is provided on the front side of the steering knuckle one.

[0016] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the rotation of the knob drives the first metal gear to rotate, and the rotation of the first metal gear rotates synchronously through the meshing connection of the second metal gear. The rotation of the second metal gear can drive the threaded rod on the rear side to rotate, and the rotation of the threaded rod can drive the moving disk to move back and forth within a certain distance. Since a trapezoidal deflection plate is provided on the outside of the moving disk, the deflection plate will be pushed outward, and the cleaning plate will be pushed outward, further activating the motor. The motor drives the rotating disk and the cleaning plate with changed position to rotate. Through the above structure, the cleaning of pipes of different radii can be realized, eliminating the need to match different pipe cleaning tools according to different pipes, simplifying the operation steps and thus improving the cleaning efficiency.

[0022] 2. In this utility model, the motor is started, and the motor drives the sector gear to rotate. The rotation of the sector gear can drive the racks at the left and right ends to move back and forth intermittently. The back and forth movement of the racks drives the fixed sliding ring to move back and forth. At the same time, the sliding ring plays a role in fixing and limiting. The sliding ring also drives the flushing plate to move back and forth. The flushing plate is also connected to a water storage tank. The water storage tank brings the internal water flow to the flushing plate for flushing. Through the above structure, the pipe flushing after the first step of cleaning is achieved.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a natural gas pipeline cleaning device, including a frame 1. A knob 3 is located in the middle of the frame 1. Rotating the knob 3 causes a metal gear 4 to rotate. The frame 1 is rotatably connected to a metal gear 5, which rotates synchronously with the meshing metal gear 5. A threaded rod 6 is connected to the rear of the metal gear 5. Rotating the metal gear 5 causes the threaded rod 6 to rotate. The threaded rod 6 is threadedly connected to a movable disc 7. Rotating the threaded rod 6 causes the movable disc 7 to move back and forth within a certain distance. Three deflection plates 8 are equidistantly arranged on the outer side of the movable disc 7, thus the deflection plates 8 are pushed outwards. A cleaning plate 9 is connected to the top, and a rotating disk 10 is slidably connected to the cleaning plate 9. A motor 11 is connected to the rear of the rotating disk 10. The cleaning plate 9 is then pushed out, and the motor 11 is further activated. The motor drives the rotating disk 10 and the cleaning plate 9, which has changed position, to rotate. The above structure enables the cleaning of pipes of different radii. A flushing mechanism 2 is set on the front side of the frame 1. The flushing mechanism 2 is used to flush the surface of the pipe. Multiple sliding wheels 12 are equidistantly installed on the outer side of the frame 1. Springs 13 are set on the outer side of the sliding wheels 12. The sliding wheels 12 help to keep the machine moving stably during operation. A handle 14 is installed on the front side of the frame 1. Screws 15 are threadedly connected to the left and right ends of the handle 14. The handle 14 helps the operator to drag it.

[0032] Specifically, when the operator manually rotates knob 3, a metal gear 4 is connected to the rear of knob 3. Rotating knob 3 drives metal gear 4 to rotate. A metal gear 5 is rotatably connected to the frame 1. During rotation, metal gear 4 meshes with metal gear 5, causing metal gear 5 to rotate synchronously. A threaded rod 6 is connected to the rear of metal gear 5. Rotating metal gear 5 drives the threaded rod 6 to rotate. The threaded rod 6 is threadedly connected to a moving disk 7. Rotating the threaded rod 6 causes the moving disk 7 to move back and forth within a certain distance. Three deflecting plates 8 are equidistantly arranged on the outer side of the moving disk 7. Therefore, the deflecting plates 8 are pushed outwards accordingly. A cleaning plate 9 is connected to the top of the deflecting plate 8. The cleaning plate 9 is slidably connected to a rotating disk 10. A motor 11 is connected to the rear of the rotating disk 10. The cleaning plate 9 is then pushed outwards, further activating... The motor 11 drives the rotating disk 10 and the cleaning plate 9, which changes position, to rotate. Through this series of interconnected structural designs and coordinated operation, the cleaning function of pipes with different radii is realized. A flushing mechanism 2 is set on the front side of the frame 1. The flushing mechanism 2 is used to flush the surface of the pipe. Multiple sliding wheels 12 are installed at equal intervals on the outside of the frame 1. Springs 13 are set on the outside of the sliding wheels 12. In actual operation, the sliding wheels 12 can help the equipment move stably on the pipe surface, and the springs 13 can play a buffering role, enhance the stability of the equipment during movement, and reduce the vibration caused by uneven pipe surface. A handle 14 is installed on the front side of the frame 1. The left and right ends of the handle 14 are connected to screws 15 by threads. The handle 14 is used to facilitate the operator to drag. The operator can easily drag the entire equipment by holding the handle 14.

[0033] Reference Figure 1 , Figure 2 and Figure 4The rinsing mechanism 2 includes a second motor 201, which is located at the rear end of the knob 3. When the second motor 201 is started, its output end is connected to a sector gear 202, causing the sector gear 202 to rotate. The second motor 201 is slidably connected to a rack 203, and the sector gear 202 and rack 203 are meshed together. The rotation of the sector gear 202 causes the rack 203 at its left and right ends to move back and forth intermittently. A sliding ring 204 is connected to the outer side of the rack 203. The back-and-forth movement of the rack 203 causes the fixed sliding ring 204 to move back and forth. Sliding strips 205 are connected to the left and right ends of the sliding ring 204. Meanwhile, the sliding strip 205 serves to fix and limit the movement. The outer side of the sliding ring 204 is connected to the flushing plate 206. The sliding ring 204 also drives the flushing plate 206 to move back and forth. The top of the flushing plate 206 is connected to the water storage tank 207. The water storage tank 207 brings the internal water flow to the flushing plate 206 for flushing. Through the above structure, the pipe is flushed after the first step of cleaning. The top of the water storage tank 207 is connected to the reinforcing plate 16, which serves to reinforce and fix the pipe. The outer side of the knob 3 is connected to the first steering knuckle 17 by rotation. The second steering knuckle 18 is set in front of the first steering knuckle 17. Through their cooperation, the machine can move flexibly in the pipe.

[0034] Specifically, when flushing is required on the pipes after the first step of cleaning, starting motor 201 is the initial action of the entire flushing process. A sector gear 202 is connected to the output end of motor 201, driving it to rotate. Motor 201 is slidably connected to a rack 203, and the sector gear 202 and rack 203 are meshed together. When the sector gear 202 rotates, its sector-shaped profile interacts with the teeth of the rack 203, causing the rack 203 located at its left and right ends to move back and forth intermittently in a regular pattern. A sliding ring 204 is connected to the outside of the rack 203. The back-and-forth movement of the rack 203 causes the fixed sliding ring 204 to move back and forth. Sliding strips 205 are connected to the left and right ends of the sliding ring 204, serving both fixing and limiting functions. A flushing plate 206 is connected to the outside of the sliding ring 204. When the flushing plate 206 moves within the sliding ring... As the machine moves back and forth driven by 204, water flows out from the flushing plate 206, thoroughly rinsing the pipe surface after the first cleaning step. Through this collaborative structure, the pipe rinsing function is achieved. The top of the flushing plate 206 is connected to a water storage tank 207, which carries the internal water flow to the flushing plate 206. Through the above structure, the pipe after the first cleaning step is rinsed. The top of the water storage tank 207 is connected to a reinforcing plate 16, which serves to reinforce and fix the water storage tank 207, enhancing its stability in the entire equipment. The knob 3 is connected to a steering joint 17 by rotation, and a steering joint 28 is set in front of the steering joint 17. Through their cooperation, the machine can move flexibly inside the pipe, allowing it to adapt smoothly to the complex and changing environment inside the pipe and shuttle through pipes with different directions and curvatures to complete the cleaning and rinsing work.

[0035] Reference Figure 1 , Figure 2 and Figure 4 A warning sign 22 is provided on the right side of motor 11. The warning sign 22 is connected to screw 2 19 by a threaded connection. The warning sign 22 is connected to the frame 1 by screw 2 19 by a threaded connection. The warning sign 22 serves to remind and warn. A reinforcing plate 20 is provided on the front side of motor 11. The reinforcing plate 20 is connected to screw 3 21 by a threaded connection. The reinforcing plate 20 serves to fix motor 11.

[0036] Specifically, a warning sign 22 is installed on the right side of motor 11. The warning sign 22 is connected to screw 29 by a threaded connection. The warning sign 22 is connected to the frame 1 by screw 29 by a threaded connection. The warning sign 22 serves to remind and warn, preventing people from approaching the running motor 11 due to misoperation or negligence, thereby avoiding potential safety accidents and ensuring the safe operation of the equipment. A reinforcing plate 20 is installed on the front side of motor 11. The reinforcing plate 20 is connected to screw 31 by a threaded connection. The reinforcing plate 20 serves to fix motor 11, ensuring that motor 11 can output power smoothly and provide a stable power source for the rotation of cleaning plate 9, thereby ensuring the efficient operation of the entire pipeline cleaning work.

[0037] Working principle: Rotating knob 3 drives metal gear 4 to rotate. Simultaneously, the rotation of metal gear 4 is synchronized with the meshing metal gear 5. The rotation of metal gear 5 drives the threaded rod 6 on the rear side to rotate. The rotation of threaded rod 6 drives the moving disk 7 to move back and forth within a certain distance. Since the moving disk 7 is provided with a trapezoidal deflection plate 8, the deflection plate 8 will be pushed outward, and the cleaning plate 9 will be pushed outward. This further starts motor 11, which drives the rotating disk 10 and the cleaning plate 9 with changed position to rotate. Through the above structure, the cleaning of pipes with different radii is realized.

[0038] Then, motor 201 is started, which drives sector gear 202 to rotate. The rotation of sector gear 202 can drive racks 203 at the left and right ends to move back and forth intermittently. The back and forth movement of racks 203 drives the fixed sliding ring 204 to move back and forth. At the same time, sliding bar 205 plays a role in fixing and limiting. Sliding ring 204 also drives flushing plate 206 to move back and forth. Simultaneously, flushing plate 206 is also connected to water storage tank 207. Water storage tank 207 brings internal water to flushing plate 206 for flushing. Through the above structure, the pipe flushing after the first step of cleaning is achieved.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
