Description

Technical Field

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

[0002] Natural gas pipelines are pipelines that transport natural gas from extraction sites or processing plants to urban gas distribution centers or industrial users. They are also known as gas transmission pipelines. During the extraction and transportation process, natural gas carries some impurities. For example, at the extraction site, natural gas may be mixed with solid impurities such as mud, sand, and rock particles from the strata. Over time, these impurities will gradually accumulate in the pipeline. If they are not cleaned in time, when the impurities accumulate to a certain extent, they will reduce the effective inner diameter of the pipeline and increase the resistance to the flow of natural gas.

[0003] Chinese Patent Application Publication No. CN202420599748.7 discloses a natural gas pipeline cleaning device. This solution uses a crossbar and a cleaning brush to clean the inner wall of the natural gas pipeline. However, the diameter of natural gas pipelines varies depending on factors such as application, transmission distance, and laying environment. During cleaning, different sizes of cleaning equipment need to be selected according to the pipeline diameter, resulting in high equipment procurement and management costs. Furthermore, the pipeline network is complex, and the pipe diameter changes frequently, requiring repeated replacement of cleaning equipment of different sizes. The natural gas pipeline cleaning device mentioned in the aforementioned patent has a fixed length for the crossbar and cleaning brush. When cleaning pipelines of different diameters, it is not convenient to adjust the length of the crossbar and cleaning brush according to the pipe diameter. It is still necessary to select a crossbar and cleaning brush of the appropriate size according to the pipe diameter, which limits the scope of application and is not conducive to reducing equipment procurement and management costs and the time required to replace equipment when the pipe diameter changes frequently.

[0004] Therefore, we propose a natural gas pipeline cleaning device. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a natural gas pipeline cleaning device. This device is constructed by setting up an overall architecture comprising three main parts: a drive assembly, a control assembly, and a cleaning assembly. In the drive assembly, the sliding connection between the chassis and the sliding column, and the fixed connection between the sliding column and the raised plate, lay the foundation for subsequent adjustments based on different pipe diameters. In the cleaning assembly, electric wheels mounted on a wheel frame enable movement. Furthermore, the cooperation of the connecting block, connecting plate, spring, and scraper allows the scraper to both contact the inner wall of the pipeline and undergo adaptive fine-tuning via the spring, thereby achieving the function of cleaning the inner wall of the natural gas pipeline and adapting to different pipe wall conditions.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A natural gas pipeline cleaning device includes a drive assembly, a control assembly at the top of the drive assembly, and a cleaning assembly at the bottom of the drive assembly. The drive assembly includes a chassis, a plurality of equidistant sliding columns are slidably connected to the middle of the chassis, and a protruding plate is fixedly connected to the bottom of the sliding columns. The cleaning assembly includes a wheel frame fixedly installed in the middle of the protruding plate, a plurality of equidistant electric wheels are rotatably connected to the inner wall of the wheel frame, a connecting block is fixedly connected to the bottom of the wheel frame, a connecting plate is slidably connected inside the connecting block, the bottom end of the connecting plate passes through the bottom end of the connecting block and is fixedly connected to a scraper, and a plurality of springs are fixedly connected inside the connecting block, with the end of each spring away from the connecting block fixedly connected to the connecting plate.

[0008] The natural gas pipeline cleaning device is constructed by setting up an overall architecture that includes three main parts: a drive component, a control component, and a cleaning component. In the drive component, the sliding connection between the chassis and the sliding column, and the fixed connection between the sliding column and the raised plate, lay the foundation for subsequent adjustments according to different pipe diameters. In the cleaning component, the electric wheels mounted on the wheel frame enable movement, and the cooperation of the connecting block, connecting plate, spring, and scraper allows the scraper to both contact the inner wall of the pipeline and make adaptive fine adjustments through the spring, thereby achieving the function of cleaning the inner wall of the natural gas pipeline and adapting to different pipe wall conditions.

[0009] Furthermore, the drive assembly also includes a housing disposed above the chassis, with a shaft fixedly connected to the bottom end of the housing. The bottom end of the shaft penetrates the bottom end of the chassis, and a driven gear is disposed in the middle of the shaft and inside the housing. The driven gear is fixedly connected to the shaft.

[0010] Furthermore, a motor is fixedly connected inside the housing, and a transmission gear is fixedly connected to the transmission end of the motor, the transmission gear meshing with the driven gear.

[0011] Furthermore, an electric push rod is fixedly connected inside the housing, and a transmission rod is fixedly connected to the transmission end of the electric push rod. The end of the transmission rod away from the electric push rod passes through the bottom end of the shaft and is rotatably connected to a sleeve.

[0012] Furthermore, a plurality of equidistant fixing plates are fixedly connected to the middle of the sleeve, and a pair of equidistant connecting rods are rotatably connected to the middle of the fixing plates, with the end of the connecting rod away from the fixing plate being rotatably connected to the protruding plate.

[0013] Furthermore, the control component includes a fixing block fixedly installed on the top of the housing, and a connecting wire is fixedly connected to the middle of the fixing block.

[0014] Furthermore, a remote control is fixedly connected to one end of the connecting line away from the fixing block, and the remote control is electrically connected to the connecting line.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. The cleaning assembly is opened by the protruding plate of the drive component. When opened, the cleaning assembly can fit against the inner wall of the natural gas pipeline. When cleaning natural gas pipelines of different diameters, the opening degree of the protruding plate can be adjusted according to the size of the pipeline, so that the cleaning assembly can be adapted to natural gas pipelines of different diameters. This ensures that the scraper of the cleaning assembly can fit tightly against the inner wall of the natural gas pipeline, making the cleaning assembly adaptable to natural gas pipelines of various diameters. This adaptability avoids the need to equip each pipeline with a special cleaning tool, greatly improves the versatility of the cleaning device, saves equipment procurement and management costs, reduces the time required to replace different equipment due to different pipeline diameters, and improves work efficiency.

[0017] 2. The electric push rod of the drive assembly and other components of the drive assembly work together to move the sleeve of the electric push rod up and down. The sleeve, together with the connecting rod and the sliding column, causes the protruding plate to open or close.

[0018] 3. The motor, transmission gears, and driven gears drive the shaft to rotate, which in turn drives the chassis and components connected to the chassis to rotate, thus causing the cleaning assembly to rotate.

[0019] 4. The scraper of the cleaning component scrapes the inner wall of the natural gas pipeline. At the same time, the spring facilitates the connecting plate to drive the scraper for fine adjustment, so that the scraper can better adapt to the inner wall of the natural gas pipeline. If the dirt on the inner wall of the natural gas pipeline is unevenly distributed, the spring can give the scraper independent adjustment space, which is convenient for multiple scrapers to self-adapt and fine adjust.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0030] Reference Figures 1-7 As shown, a natural gas pipeline cleaning device according to a preferred embodiment of the present invention includes a drive assembly 1, a control assembly 2 at the top of the drive assembly 1, and a cleaning assembly 3 at the bottom of the drive assembly 1. The drive assembly 1 includes a chassis 102, a plurality of equidistant sliding columns 113 are slidably connected to the middle of the chassis 102, and a protruding plate 112 is fixedly connected to the bottom of the sliding columns 113. The cleaning assembly 3 includes a wheel frame 301 fixedly installed in the middle of the protruding plate 112, a plurality of equidistant electric wheels 302 are rotatably connected to the inner wall of the wheel frame 301, a connecting block 303 is fixedly connected to the bottom of the wheel frame 301, a connecting plate 304 is slidably connected inside the connecting block 303, the bottom end of the connecting plate 304 passes through the bottom end of the connecting block 303 and is fixedly connected to a scraper 306, and a plurality of springs 305 are fixedly connected inside the connecting block 303, with the end of the spring 305 away from the connecting block 303 fixedly connected to the connecting plate 304.

[0031] The natural gas pipeline cleaning device is constructed by setting up an overall architecture consisting of three main parts: drive component 1, control component 2, and cleaning component 3. In drive component 1, the sliding connection between chassis 102 and sliding column 113, and the fixed connection between sliding column 113 and protruding plate 112, lay the foundation for subsequent adjustment according to different pipe diameters. In cleaning component 3, the electric wheel 302 is installed on the wheel frame 301 to realize the movement function. And by relying on the cooperation of connecting block 303, connecting plate 304, spring 305 and scraper 306, the scraper 306 can both contact the inner wall of the pipeline and be adaptively fine-tuned by spring 305, thereby realizing the function of cleaning the inner wall of natural gas pipeline and adapting to different pipe wall conditions.

[0032] The drive assembly 1 also includes a housing 101 disposed above the chassis 102. A shaft 103 is fixedly connected to the bottom end of the housing 101. The bottom end of the shaft 103 passes through the bottom end of the chassis 102. A driven gear 104 is disposed in the middle of the shaft 103 and inside the housing 101. The driven gear 104 is fixedly connected to the shaft 103.

[0033] By setting a housing 101 above the chassis 102, and having a shaft 103 at the bottom of the housing 101 pass through the chassis 102, and setting a driven gear 104 fixedly connected to the shaft 103 in the middle of the shaft 103, conditions are created for subsequent power transmission and driving the rotation of related components.

[0034] A motor 105 is fixedly connected inside the housing 101, and a transmission gear 106 is fixedly connected to the transmission end of the motor 105. The transmission gear 106 meshes with the driven gear 104.

[0035] Power is transmitted from the motor 105 fixed inside the housing 101 to the shaft 103 by means of the meshing relationship between the transmission gear 106 fixedly connected to the transmission end of the motor 105 and the driven gear 104. This drives the chassis 102 connected to the shaft 103 and the related cleaning components 3 connected below the chassis 102 to rotate. This gear transmission method provides the power source for the rotation and cleaning of the entire cleaning device in the pipeline.

[0036] An electric push rod 109 is fixedly connected inside the outer casing 101. A transmission rod 108 is fixedly connected to the transmission end of the electric push rod 109. The end of the transmission rod 108 away from the electric push rod 109 passes through the bottom end of the shaft 103 and is rotatably connected to the sleeve 107.

[0037] An electric push rod 109 fixed inside the outer casing 101 has a transmission rod 108 at its transmission end that passes through the bottom end of the shaft 103 and is rotatably connected to the sleeve 107. In conjunction with the rotating connection structure of the fixed plate 110, connecting rod 111 and protruding plate 112 on the sleeve 107, when the electric push rod 109 extends or retracts, it can drive the sleeve 107 to move up and down. This allows the connecting rod 111 to push or pull the protruding plate 112 to open or close, thereby achieving the function of adjusting the degree of contact between the cleaning component 3 and the inner wall of the natural gas pipeline according to different pipe diameters.

[0038] The sleeve 107 is fixedly connected to a plurality of equidistant fixed plates 110, and the fixed plates 110 are rotatably connected to a pair of equidistant connecting rods 111, the end of the connecting rods 111 away from the fixed plates 110 being rotatably connected to the protruding plate 112.

[0039] Multiple equidistant fixing plates 110 are fixed in the middle of the sleeve 107, and a pair of equidistant connecting rods 111 are rotatably connected in the middle of the fixing plates 110. The end of the connecting rod 111 away from the fixing plate 110 is rotatably connected to the protruding plate 112. With this connection structure, when the electric push rod 109 drives the sleeve 107 to move, the connecting rod 111 can transmit force to the protruding plate 112, so that the protruding plate 112 can stably make corresponding position changes, thereby driving the cleaning assembly 3 to make an action that adapts to pipes of different diameters, and achieving effective contact cleaning of natural gas pipes of different diameters.

[0040] The control component 2 includes a fixing block 201 fixedly installed on the top of the housing 101. A connecting wire 202 is fixedly connected to the middle of the fixing block 201. The connecting wire 202 passes through the fixing block 201 and is electrically connected to the motor 105 and the electric push rod 109.

[0041] By setting a fixing block 201 at the top of the housing 101, and using the connecting line 202 fixed in the middle of the fixing block 201 to pass through the fixing block 201 and electrically connect it to the motor 105 and the electric push rod 109, a circuit connection from the control end to the power component is constructed. This allows the working state of the motor 105 and the electric push rod 109 to be controlled by external control signals, providing an electrical connection basis for remotely controlling the operation of the entire cleaning device.

[0042] A remote control 203 is fixedly connected to one end of the connecting wire 202 away from the fixing block 201, and the remote control 203 is electrically connected to the connecting wire 202;

[0043] By electrically connecting the remote controller 203 to the connecting cable 202, the remote controller 203 can be used as a remote control terminal. Operators can conveniently issue control commands outside the pipeline and transmit the commands to components such as the motor 105 and electric push rod 109 through the connecting cable 202. This allows for remote control of the cleaning device's movement and cleaning within the natural gas pipeline, as well as its adaptation to different pipe diameters, thus achieving convenient remote control functionality.

[0044] Specific implementation process: First, place the cleaning device at the inlet of the natural gas pipeline to be cleaned, and start the electric push rod 109. The electric push rod 109 starts working according to the command issued by the remote control 203. The transmission rod 108 at its transmission end moves with the extension and retraction of the electric push rod 109. Since the end of the transmission rod 108 away from the electric push rod 109 passes through the bottom end of the shaft 103 and is rotatably connected to the sleeve 107, the sleeve 107 moves up and down under the drive of the transmission rod 108. Then, as the sleeve 107 moves, multiple equidistant fixing plates 110 fixedly connected in the middle of the sleeve 107 move. In synchronous motion, a pair of equidistant connecting rods 111, rotatably connected in the middle of the fixed plate 110, play a role. The end of the connecting rod 111 away from the fixed plate 110 is rotatably connected to the protruding plate 112. With the help of this linkage structure, the protruding plate 112, under the push and pull of the connecting rods 111, drives the sliding column 113 to slide in the middle of the chassis 102, thereby realizing the opening or closing action of the cleaning component 3. The operator can precisely adjust the opening degree of the protruding plate 112 through the remote control 203 to adapt it to the diameter of the natural gas pipeline to be cleaned, ensuring that the scraper 306 in the cleaning component 3 can tightly fit the inner wall of the pipeline. Then, the motor 105 is started, and the transmission gear 106 fixedly connected to the transmission end of the motor 105 begins to rotate. Because the transmission gear 106 meshes with the driven gear 104 in the middle of the shaft 103, power can be smoothly transmitted from the motor 105 to the shaft 103. The shaft 103 drives the chassis 102 and the cleaning assembly 3 connected below the chassis 102 to rotate together to achieve a rotary scraping cleaning action on the inner wall of the natural gas pipeline. At the same time, the multiple equidistant electric wheels 302 rotatably connected to the inner wall of the wheel frame 301 of the cleaning assembly 3 also rotate synchronously, providing power for the entire cleaning device inside the pipeline. The forward propulsion allows it to move slowly along the pipeline. During the movement of the cleaning device, the scraper 306, which is fixedly connected to the bottom of the connecting block 303, scrapes the inner wall of the natural gas pipeline. If the dirt on the inner wall of the natural gas pipeline is unevenly distributed, multiple springs 305 fixedly connected inside the connecting block 303 will perform adaptive adjustment. One end of the spring 305 is fixed to the connecting block 303, and the other end is fixed to the connecting plate 304. The connecting plate 304 drives the scraper 306 to make fine adjustments according to the actual condition of the inner wall, ensuring that each scraper 306 can fit tightly against the pipe wall and efficiently remove dirt.
