Description

Technical Field

[0001] This utility model belongs to the field of pipeline cleaning devices, and in particular relates to a gas pipeline cleaning device. Background Technology

[0002] As urban pipeline networks age, natural gas pipelines rust internally, and due to a lack of cleaning over the years, scale and deposits accumulate inside. Modern cities demand higher accuracy and timeliness in pipeline maintenance, requiring the ability to quickly and accurately identify and repair problems. Pipeline repair necessitates cleaning the inside of the pipeline. Existing pipeline cleaning devices have limited functionality, are difficult to apply to pipelines of different diameters, and face difficulties in accessing or reaching certain areas, resulting in low cleaning efficiency and incomplete cleaning. Summary of the Invention

[0003] In view of this, the present invention aims to propose a gas pipeline cleaning device to solve the problems of existing pipeline cleaning devices having relatively simple functions, being difficult to apply to pipelines of different diameters, resulting in low cleaning efficiency and incomplete cleaning.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A gas pipeline cleaning device includes a walking mechanism, a drive mechanism, a linkage assembly, a first motor, and a cleaning mechanism. The linkage assembly is rotatably connected to the drive mechanism, the walking mechanism is fixedly connected to the linkage assembly, the first motor is fixedly installed at the front end of the drive mechanism, and a rotating rod is fixedly connected to the output end of the first motor. The cleaning mechanism is fixedly mounted on the rotating rod. The walking mechanism is used to move inside the pipeline. The drive mechanism moves the walking mechanism closer to or away from the inner wall of the pipeline through the linkage assembly. The cleaning mechanism is used to clean the inner wall of the pipeline.

[0006] Furthermore, the drive mechanism includes a second motor, a lead screw, guide columns, a first connecting plate, and a second connecting plate. The first connecting plate and the second connecting plate are arranged in parallel. The first connecting plate is fixedly mounted on the second motor. Three guide columns are evenly arranged along the circumference of the first connecting plate. The bottom end of each guide column is fixedly mounted on the first connecting plate, and the top end is fixedly mounted on the second connecting plate. The lead screw is fixedly connected to the output end of the second motor, and the top end of the lead screw is rotatably connected to the second connecting plate. The first motor is fixedly mounted on the second connecting plate.

[0007] Furthermore, the drive mechanism also includes a third connecting plate, which is parallel to the first connecting plate and located between the first and second connecting plates. The third connecting plate is threadedly connected to the lead screw and slidably connected to each guide post.

[0008] Furthermore, multiple traveling mechanisms are arranged circumferentially on the inner wall of the pipe. Each traveling mechanism corresponds to a linkage assembly. Each linkage assembly includes a first linkage, a second linkage, a third linkage, and a moving plate. One end of the first linkage is rotatably mounted on a first connecting plate, and one end of the second linkage is rotatably mounted on a second connecting plate. Both ends of the moving plate are rotatably connected to the other ends of the first and second linkages, respectively. One end of the third linkage is rotatably connected to the third connecting plate, and the other end is rotatably connected to the middle of the second linkage. One traveling mechanism is fixedly mounted on each moving plate.

[0009] Furthermore, the walking mechanism includes a fixed frame, a drive wheel, a moving wheel, a third motor, and a transmission belt. The fixed frame is fixedly mounted on the moving plate. The moving wheel and the drive wheel are arranged in parallel, with the moving wheel rotatably mounted at the front end of the fixed frame and the drive wheel rotatably mounted at the rear end of the fixed frame. The third motor is fixedly mounted on one side of the bottom of the fixed frame. The output end of the third motor is provided with a main gear, and the middle of the drive wheel is provided with a driven gear. The outer periphery of the main gear and the outer periphery of the driven gear form a synchronous transmission structure through the transmission belt.

[0010] Furthermore, the walking mechanism also includes elastic components. Two elastic components are arranged in parallel on the fixed frame. Each elastic component includes a compression spring and fixing members at both ends. The fixing members are T-shaped and the two fixing members are arranged symmetrically. The outer ends of the two fixed frames are respectively fixedly installed on the fixed frame and the moving plate.

[0011] Furthermore, the cleaning mechanism includes a first rotating plate, a second rotating plate, and a telescopic rod. The first rotating plate is fixedly connected to the rotating rod. The second rotating plate is parallel to the front end of the first rotating plate and is rotatably connected to the first rotating plate. The first rotating plate is uniformly provided with a plurality of first grooves, which are rectangular. The second rotating plate is uniformly provided with a plurality of second grooves, which are arc-shaped through grooves. The second grooves are not concentric with the first rotating plate. The first grooves and the second grooves correspond one-to-one. The periphery of each telescopic rod is slidably disposed in a first groove, and one side of each telescopic rod is slidably connected to the second groove.

[0012] Furthermore, each telescopic rod is provided with a cleaning plate at its outer end. The cleaning plate has an arc-shaped structure and can be fixedly installed on the telescopic rod by long bolts.

[0013] Furthermore, the cleaning mechanism also includes a fourth motor, which is fixed on the first rotating plate. The output end of the fourth motor is provided with a drive gear, and the outer periphery of the second rotating plate is evenly distributed with saw teeth. The drive gear meshes with the saw teeth.

[0014] Furthermore, the cleaning mechanism also includes a spraying device, which is fixedly installed on the first rotating plate and located at the front end of the second rotating plate. The upper end of the spraying device is provided with an injection port, and multiple nozzles are arranged around the circumference of the spraying device. The injection port is used to inject cleaning liquid.

[0015] Compared with the prior art, the cleaning device of this utility model has the following advantages:

[0016] The gas pipeline cleaning device of this utility model uses a second motor to drive a lead screw to rotate, which in turn drives a third connecting plate to rotate a third connecting rod, thereby moving a moving plate. This causes the moving wheels and drive wheels to move closer to or further away from the inner wall of the pipeline, thus adapting to different pipelines. With the addition of compression springs, each moving wheel and drive wheel can be in close contact with the inner wall of the pipeline, ensuring a more stable cleaning process and achieving better cleaning results.

[0017] (2) The gas pipeline cleaning device of this utility model drives the second rotating plate to rotate by the fourth motor. The rotation of the second rotating plate can move one end of the telescopic rod along the second groove, and then make the other end of the telescopic rod slide along the first groove, so that the cleaning plate can move closer to or away from the inner wall of the pipeline, thereby cleaning pipelines of different sizes and increasing the scope of use of the equipment.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figure 1-7As shown, a gas pipeline cleaning device includes a traveling mechanism 1, a drive mechanism 2, a connecting rod assembly 3, a first motor 4, and a cleaning mechanism 5. The connecting rod assembly 3 is rotatably connected to the drive mechanism 2, and the traveling mechanism 1 is fixedly connected to the connecting rod assembly 3. The first motor 4 is fixedly installed at the front end of the drive mechanism 2, and a rotating rod 6 is fixedly connected to the output end of the first motor 4. The cleaning mechanism 5 is fixedly mounted on the rotating rod 6. The traveling mechanism 1 is used to travel inside the pipeline. The drive mechanism 2, through the connecting rod assembly 3, moves the traveling mechanism 1 closer to or away from the inner wall of the pipeline. The cleaning mechanism 5 is used to clean the inner wall of the pipeline. The drive mechanism 2 causes the connecting rod assembly 3 to rotate. The linkage assembly 3 rotates, causing the walking mechanism 1 to move away from and closer to the inner wall of the pipe, thus enabling the walking mechanism 1 to move within pipes of different diameters. The rotation of the first motor 4 drives the rotating rod 6 to rotate, which in turn drives the cleaning mechanism 5 to rotate circumferentially along the pipe to clean the inside of the pipe. The first motor 4 is surrounded by a protective shell with a groove on it. The groove corresponds to the linkage assembly 3, allowing the linkage assembly 3 to enter the groove. When not in use, the groove serves to store the linkage assembly 3, allowing the cleaning device to be folded up and the entire device to be made more compact. At the same time, cables and batteries can be placed inside the protective shell.

[0033] like Figure 3 and 4 As shown, the drive mechanism 2 includes a second motor 21, a lead screw 22, guide columns 23, a first connecting plate 24, and a second connecting plate 25. The first connecting plate 24 and the second connecting plate 25 are arranged in parallel. The first connecting plate 24 is fixedly mounted on the second motor 21. Three guide columns 23 are evenly arranged around the first connecting plate 24. The bottom end of each guide column 23 is fixedly mounted on the first connecting plate 24, and the top end is fixedly mounted on the second connecting plate 25. The lead screw 22 is fixedly connected to the output end of the second motor 21, and the top end of the lead screw 22 is rotatably connected to the second connecting plate 25. The first motor 21 is fixedly mounted on the second connecting plate 25. The drive mechanism 2 also includes a third connecting plate 26, which is arranged parallel to the first connecting plate 24 and located between the first connecting plate 24 and the second connecting plate 25. Between the second connecting plates 25, the third connecting plate 26 is threadedly connected to the lead screw 22, and the third connecting plate 26 is slidably connected to each guide post 23; multiple traveling mechanisms 1 are arranged circumferentially on the inner wall of the pipe, each traveling mechanism 1 corresponds to a connecting rod assembly 3, each connecting rod assembly 3 includes a first connecting rod 31, a second connecting rod 32, a third connecting rod 33 and a moving plate 34, one end of the first connecting rod 31 is rotatably mounted on the first connecting plate 24, one end of the second connecting rod 32 is rotatably mounted on the second connecting plate 25, both ends of the moving plate 34 are rotatably connected to the other ends of the first connecting rod 31 and the second connecting rod 32 respectively, one end of the third connecting rod 33 is rotatably connected to the third connecting plate 26 and the other end is rotatably connected to the middle of the second connecting rod 32, and one traveling mechanism 1 is fixedly mounted on each moving plate 34; Figure 5 As shown, the walking mechanism 1 includes a fixed frame 11, a drive wheel 12, a movable wheel 13, a third motor 14, and a transmission belt 15. The fixed frame 11 is fixedly mounted on the movable plate 34. The movable wheel 13 and the drive wheel 12 are arranged in parallel, with the movable wheel 13 rotatably mounted at the front end of the fixed frame 11 and the drive wheel 12 rotatably mounted at the rear end of the fixed frame 11. The third motor 14 is fixedly mounted on one side of the bottom of the fixed frame 11. The output end of the third motor 14 is provided with a main gear, and the middle of the drive wheel 12 is provided with a driven gear. The periphery of the main gear and the periphery of the driven gear form a synchronous transmission structure through the transmission belt 15.

[0034] During implementation, the cleaning device is placed into the pipe to be cleaned. The first motor 4 rotates, driving the lead screw 22 to rotate. The rotation of the lead screw 22 causes the third connecting plate 26 to move closer to or away from the second motor 21. This, in turn, causes the third connecting rod 33 to push the second connecting rod 32 closer to or away from the inner wall of the pipe. Furthermore, the second connecting rod 32 and the first connecting rod 31 work together to move the moving plate 34 closer to or away from the inner wall of the pipe, thus allowing the traveling mechanism 1 to move closer to or away from the inner wall of the pipe, enabling it to travel within different pipes. The drive wheel 12 and the moving wheel 13 are each equipped with a set of wheels, increasing the contact area between the drive wheel 12 and the moving wheel 13 and the inner wall of the pipe, allowing them to move stably within the pipe and reducing the possibility of slipping on the inner wall. This ensures that the cleaning mechanism 5 can thoroughly clean the inside of the pipe. The third motor 14 rotates, driving... The main gear rotates, which in turn drives the driven gear to rotate via the transmission belt 15. This, in turn, causes the drive wheel 12 to move forward along the pipeline via the third motor 14. The movement of the drive wheel 12 pushes the moving wheel 13 forward. The drive wheel 12 is positioned behind the moving wheel 13 along the direction of movement, which can better propel the entire device forward. The walking mechanism 1 also includes elastic components 16. Two elastic components 16 are arranged in parallel on the fixed frame 11. Each elastic component (16) includes a compression spring and fixing members at both ends. The fixing members are T-shaped and the two fixing members are symmetrically arranged. The outer ends of the two fixed frames are respectively fixedly installed on the fixed frame 11 and the moving plate 34. The compression spring can make the drive wheel 12 and the moving wheel 13 contact the inside of the pipeline more tightly, ensuring stable forward movement inside the pipeline.

[0035] like Figure 6-7As shown, the cleaning mechanism 5 includes a first rotating plate 51, a second rotating plate 52, and a telescopic rod 53. The first rotating plate 51 is fixedly connected to the rotating rod 6. The second rotating plate 52 is arranged parallel to the first rotating plate 51 and is rotatably connected to the first rotating plate 51. The first rotating plate 51 has a plurality of uniformly arranged first grooves, which are rectangular through slots. The second rotating plate 52 has a plurality of uniformly arranged second grooves, which are arc-shaped through slots. The second grooves are not concentric with the first rotating plate 51. The first grooves and second grooves correspond one-to-one. The periphery of each telescopic rod 53 is slidably disposed within a first groove, and one side of each telescopic rod 53 is slidably connected to a second groove. Each telescopic rod 53 has a cleaning plate 54 at its outer end. The cleaning plate 54 has an arc-shaped structure and can... The cleaning mechanism 5 is fixedly mounted on the telescopic rod 53 by long bolts. The cleaning plate 54 is detachable for easy replacement. Different types of cleaning plates, such as brushes or rubber scrapers, can be replaced to meet different cleaning requirements. The cleaning mechanism 5 also includes a fourth motor 55, which is fixed on the first rotating plate 51. The output end of the fourth motor 55 is provided with a drive gear. The outer periphery of the second rotating plate 52 is evenly distributed with saw teeth, and the drive gear meshes with the saw teeth. The cleaning mechanism 5 also includes a spraying device 56, which is fixedly mounted on the first rotating plate 51 and located at the front end of the second rotating plate 52. The upper end of the spraying device 56 is provided with an injection port, and multiple nozzles are arranged around the circumference of the spraying device 56. The injection port is used to inject cleaning liquid, and the nozzles spray the cleaning liquid outward by centrifugal force.

[0036] In implementation, a fourth connecting plate is provided at the output end of the first motor 4, and the fourth connecting plate is rotatably connected to the rotating rod 6. Multiple positioning posts are evenly arranged circumferentially at the lower end of the third connecting plate 26, and the free end of each positioning post is fixedly installed on the second connecting plate 25. During cleaning, the fourth connecting plate can block dirt and protect the first motor 4. The rotation of the first motor 4 drives the rotating rod 6 to rotate, which in turn drives the first rotating plate 51 to rotate, thereby causing the cleaning plate 54 to rotate circumferentially within the pipe. The rotation of the fourth motor 55, through the drive gear at its output end, drives the second rotating plate 52 to rotate. The rotation of the second rotating plate 52 allows the telescopic rod 53 to move within... The end moves along the second groove, thereby allowing the telescopic rod 53 to move along the first groove, so that the cleaning plate 54 comes into close contact with the inner wall of the pipe. This allows the cleaning mechanism 5 to adapt to pipes of different inner diameters, increasing the range of applications of the equipment. When the dirt on the inner wall of the pipe is difficult to clean, a suitable cleaning liquid can be injected through the injection port using the spraying device 56. When the first motor 4 drives the rotating rod 6 to rotate, the rotating rod 6 drives the first rotating plate 51 to rotate, which in turn drives the spraying device 56 to rotate. Through the centrifugal force generated by the rotation, the nozzle sprays the cleaning liquid onto the inner wall of the pipe, and the cleaning plate 54 cleans the inner wall of the pipe, thus cleaning the pipe.

[0037] The working principle of a gas pipeline cleaning device is as follows: During operation, the cleaning device is placed inside the pipeline to be cleaned. The position of the third connecting plate 26 is set by the second motor 21 (existing technology, model 95ZWS600). The third connecting rod 33 drives the moving plate 34 to move, thereby driving the moving wheel 13 and the drive wheel 12 to approach the inner wall of the pipeline, so that each moving wheel 13 and drive wheel 12 is in close contact with the inner wall of the pipeline. The fourth motor 55 drives the second rotating plate 52 to rotate, causing the telescopic rod 53 to move along the first groove, thereby making the cleaning plate 54 in close contact with the inner wall of the pipeline. The third motor 14 (existing technology, model 95ZWSX series) is started to drive the drive wheel 12 to move forward along the inner wall of the pipeline. The first motor 4 (existing technology, model 95ZWS600) is started to drive the rotating rod 6 to rotate, thereby driving the first rotating plate 51 to rotate, so that the cleaning plate 54 cleans the inner wall of the pipeline.

[0038] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
