Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning equipment technology, specifically to an autonomous power pipeline cleaning device. Background Technology

[0002] A pipeline cleaning tool is a tool used for cleaning, inspecting, and maintaining the inside of natural gas pipelines. It is usually made of polymer materials (such as polyurethane or rubber) or metal, and is cylindrical or bullet-shaped with a diameter slightly larger than the inner diameter of the pipeline in order to form a seal inside the pipeline and be propelled forward by the gas flow.

[0003] In existing technologies, some pipeline cleaning pigs experience a gradual decrease in diameter on their outer side due to prolonged friction with the inner wall of the pipeline during the cleaning process. This results in gaps between the outer side of the pig and the inner wall of the pipeline, preventing the pig from adhering tightly to the pipe wall during cleaning. Consequently, the cleaning effect of the pig on stubborn dirt such as rust and oil on the inner wall of the pipeline is greatly reduced, making it difficult to achieve the expected cleaning standards. Therefore, we propose an autonomous power-driven pipeline cleaning pig. Utility Model Content

[0004] The purpose of this utility model is to provide an autonomous power-driven pipeline cleaning tool to solve the problem mentioned in the background art that the pipeline cleaning tool is in long-term frictional contact with the inner wall of the pipeline, and the outer side of the pipeline cleaning tool will wear down, making it impossible for the pipeline cleaning tool to fit tightly against the pipeline wall during the cleaning process. This greatly reduces the cleaning effect on stubborn dirt such as rust and oil on the inner wall of the pipeline, making it difficult to achieve the expected cleaning standard.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an autonomous power pipeline cleaning device, comprising a mounting base and four base plates. Four connecting strips are fixedly connected to the outer side of the mounting base, and push plates are fixedly connected to the front side of the four connecting strips. Rubber rings are fixedly connected to the outer side of the four base plates, with the front side of the rubber rings contacting the rear end of the push plates. Three connecting strips are fixedly connected to the outer side of the mounting base, and a mounting column is fixedly connected to one end of each of the three connecting strips. Three drive wheels are installed on the outer side of the mounting column. The mounting base is equipped with a clamping mechanism for tightly fitting the rubber rings to the inside of the pipeline.

[0006] The clamping mechanism includes a sliding rod that is slidably connected inside the mounting seat, and a pressing rod is fixedly connected to the front side of the sliding rod.

[0007] The outer side of the extrusion rod contacts the outer side of the four base plates, and the outer side of the sliding rod is fixedly connected to a push ring.

[0008] The sliding rod is fitted with a push spring on its outer side, and the four connecting bars are all fixedly connected to limit blocks on their outer sides.

[0009] Each of the four films has a limiting groove inside, and the outer sides of the four connecting strips are slidably connected to the inside of the four limiting grooves.

[0010] The rear end of the mounting base is fixedly connected to an electric push rod, and the drive end of the electric push rod is fixedly connected to a pusher.

[0011] The actuator has three rotatable push rods inside, and one end of each push rod is rotatably connected to the outside of three drive wheels.

[0012] This utility model has at least the following beneficial effects:

[0013] By having the push spring push the push ring, which in turn drives the squeeze rod to push open the four bottom plates, the four bottom plates expand the rubber ring, thus ensuring that the rubber ring is always in close contact with the inner wall of the pipe. This prevents gaps between the pig and the inner wall of the pipe, improves the cleaning effect of the pig on the dirt on the inner wall of the pipe, and ensures that the expected cleaning standards are not affected.

[0022] 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.

[0023] Example 1

[0024] Please see Figures 1 to 7 This utility model provides a technical solution: an autonomous power pigging tool, including a mounting base 1 and four base plates 4. The mounting base 1 is designed to facilitate the fixing of connecting strip 1 2 and connecting strip 2 6. Four connecting strips 1 2 are fixedly connected to the outer side of the mounting base 1. The connecting strips 1 2 are designed to connect push plates 3 and limit the base plates 4 by cooperating with limiting grooves 1206. Push plates 3 are fixedly connected to the front side of the four connecting strips 1 2. Push plates 3 are designed to push away dirt on the front side. Rubber rings 5 ​​are fixedly connected to the outer side of the four base plates 4. Rubber rings 5 ​​are designed to facilitate... The dirt on the outside of the pipe is scraped off. The front side of the rubber ring 5 contacts the rear end of the push plate 3. Three connecting strips 2 6 are fixedly connected to the outside of the mounting base 1. The design of the connecting strips 2 6 is to connect the mounting base 1 and the mounting column 7. One end of the three connecting strips 2 6 is fixedly connected to the mounting column 7. The design of the mounting column 7 is to facilitate the installation of three drive wheels 8. Three drive wheels 8 are installed on the outside of the mounting column 7. The design of the drive wheels 8 is to drive the entire pig to move inside the pipe. The inside of the mounting base 1 is equipped with a tight-fitting mechanism 12 for making the rubber ring 5 fit tightly against the inside of the pipe.

[0025] The pressing mechanism 12 includes a sliding rod 1201 that is slidably connected inside the mounting base 1. The sliding rod 1201 is designed to connect to the extrusion rod 1202. The extrusion rod 1202 is fixedly connected to the front side of the sliding rod 1201. The extrusion rod 1202 is designed to squeeze open the four bottom pieces 4.

[0026] The outer side of the extrusion rod 1202 contacts the outer side of the four base plates 4. The extrusion rod 1202 is designed to push the four base plates 4 apart. The outer side of the sliding rod 1201 is fixedly connected to the push ring 1203. The push ring 1203 is designed to drive the extrusion rod 1202 under the push of the push spring 1204.

[0027] A push spring 1204 is sleeved on the outer side of the sliding rod 1201. The push spring 1204 is designed to push the push ring 1203, thereby driving the extrusion rod 1202, which in turn squeezes open the four bottom pieces 4. Limiting blocks 1205 are fixedly connected to the outer sides of the four connecting strips 1201. The limiting blocks 1205 are designed to limit the bottom pieces 4 and prevent them from moving backward.

[0028] Each of the four base plates 4 has a limiting groove 1206 inside. The limiting groove 1206 is designed to facilitate the passage and sliding of the connecting strip 2 inside the base plate 4. The outer sides of the four connecting strips 2 are slidably connected to the inside of the four limiting grooves 1206 respectively. When the pig is in use, the push plate 3 and the rubber ring 5 work together to clean the dirt inside the pipe. During cleaning, the rubber ring 5 will fit tightly against the inner wall of the pipe. When the rubber ring 5 wears, the push spring 1204 will push the push ring 1203, which will drive the squeezing rod 120. 2. The squeezing rod 1202 pushes open the four bottom plates 4. The four bottom plates 4 push the rubber ring 5 from inside the rubber ring 5, so that the rubber ring 5 is always in close contact with the inner wall of the pipe. The pushing spring 1204 pushes the pushing ring 1203, which drives the squeezing rod 1202 to push open the four bottom plates 4. The four bottom plates 4 then spread the rubber ring 5, so that the rubber ring 5 is always in close contact with the inner wall of the pipe. This prevents gaps between the pig and the inner wall of the pipe, improves the cleaning effect of the pig on the dirt on the inner wall of the pipe, and ensures that the expected cleaning standard is not affected.

[0029] Example 2

[0030] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that an electric push rod 9 is fixedly connected to the rear end of the mounting base 1. The electric push rod 9 is designed to push the pusher 10, thereby driving the three push rods 11. The drive end of the electric push rod 9 is fixedly connected to the pusher 10. The pusher 10 is designed to connect the electric push rod 9 and the push rods 11.

[0031] The pusher 10 has three push rods 11 rotatably connected inside. The push rods 11 are designed to connect the pusher 10 and the drive wheel 8. One end of each of the three push rods 11 is rotatably connected to the outside of the three drive wheels 8. When the electric push rod 9 pushes the pusher 10, the pusher 10 will drive the three push rods 11, which will push the drive wheels 8, allowing the drive wheels 8 to unfold and also fit against the inner wall of the pipeline, increasing friction and making the pig operation more stable.
