Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, specifically to a cleaning device for natural gas pipeline construction. Background Technology

[0002] Natural gas pipelines are pipelines that transport natural gas (including associated gas from oil fields) from extraction sites or processing plants to urban gas distribution centers or industrial users. They are also known as gas transmission pipelines. Using natural gas pipelines to transport natural gas is a way to transport large quantities of natural gas on land. During the construction of new natural gas pipelines, it is necessary to clean the pipeline to ensure the cleanliness of the pipeline interior and avoid damage to the pipeline caused by impurities and pollutants.

[0003] For example, Chinese patent (CN222778553U) discloses a cleaning device for natural gas pipeline construction, applied in the field of cleaning devices. It includes a connecting pipe, with a connecting cylinder rotatably connected to its surface via a bearing. A mounting base is provided on the surface of the connecting cylinder. One end of the connecting pipe is rotatably connected to a rotating cavity via a waterproof bearing, and a nozzle is connected to the surface of the rotating cavity. This invention uses a nozzle mounted on the rotating cavity. When an external water supply device delivers water to the connecting pipe through an external water pipe, the water reaches the rotating cavity. Under the action of the nozzle, a high-pressure impact water column is formed, pushing the rotating cavity forward. Simultaneously, the rotating cavity rotates, causing the cleaning brushes mounted on the fixed base to rotate. This achieves the purpose of cleaning the inner wall of the pipeline using the cleaning brushes. The water flow formed by the high-pressure water column can impact the cleaned impurities and dust to the outside of the pipeline, improving practicality.

[0004] The aforementioned devices cannot move autonomously and require external traction ropes to move inside the pipeline. This external traction limits the autonomous working efficiency of the cleaning device within the pipeline. Furthermore, when adapting to the pipeline diameter, the position of the moving wheels needs to be manually adjusted before entering the pipeline. Due to the need for manual adjustment, improper adjustments may occur, such as inaccurate adjustment or forgetting to adjust. This may cause the equipment to be unable to move smoothly in the pipeline, or even cause jamming, equipment damage, or affect the cleaning effect. If there are multiple sections with different diameters inside the pipeline, the device needs to be removed and readjusted, reducing the cleaning efficiency. To address the above problems, a cleaning device for natural gas pipeline construction is proposed to solve these issues. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a cleaning device for natural gas pipeline construction. This solves the problem that current methods cannot achieve autonomous movement and require external traction to move within the pipeline. The external traction limits the cleaning device's autonomous working efficiency within the pipeline. Furthermore, when adapting to the pipeline diameter, the position of the moving wheels needs to be manually adjusted before entering the pipeline. Because manual adjustment is required, improper adjustments may occur, such as inaccurate positioning or forgetting to adjust. This can lead to the device being unable to move smoothly within the pipeline, or even jamming, damage to the device, or affecting the cleaning effect. If there are multiple sections with different diameters within the pipeline, the device needs to be removed and readjusted, further reducing cleaning efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a cleaning device for natural gas pipeline construction, comprising an installation sleeve, wherein a first motor is fixedly connected to the left side wall inside the installation sleeve, the output shaft of the first motor passes through the left side wall of the installation sleeve and is fixedly connected to a rotating disk, a ring of cleaning bristles is fixedly connected to the outside of the rotating disk, fixing plates are fixedly connected to both the left and right sides inside the installation sleeve, at least three limiting rods are fixedly connected between the two fixing plates, a movable plate is also provided between the two fixing plates, the movable plate is slidably connected to the limiting rods, and at least three sets of moving components are provided on the outside of the installation sleeve.

[0007] Preferably, a threaded rod is rotatably connected between the two fixed plates at the middle, the outer surface of the threaded rod is threaded to the middle of the moving plate, a second motor for driving the threaded rod to rotate is fixedly installed on the side of the right fixed plate, and a traction hook is fixedly connected to the middle of the right side of the mounting sleeve.

[0008] Preferably, the movable component includes a connecting plate, a first connecting rod rotatably connected to the middle of the connecting plate, a first connecting lug rotatably connected to the bottom of the first connecting rod via a rotating shaft, and the first connecting lug being fixedly connected to the left side of the outer surface of the mounting sleeve.

[0009] Preferably, the middle part of the first connecting rod is rotatably connected to the second connecting rod via a pivot, and the end of the second connecting rod is rotatably connected to the second connecting lug via a pivot. The second connecting lug is fixedly connected to the side of the moving plate.

[0010] Preferably, the connecting plate is fixedly connected to mounting brackets at both the front and rear ends, and rotating rods are rotatably connected to the left and right sides of the two sets of mounting brackets. The front and rear ends of the rotating rods pass through the two mounting brackets and are fixedly connected to the traveling wheels. A traveling belt is connected between the front and rear traveling wheels.

[0011] Preferably, a second bevel gear is fixedly connected to the outer surface of the rotating rod on the right, and a mounting plate is fixedly connected between the two sets of mounting brackets near the second bevel gear. A third motor is fixedly connected to the upper surface of the mounting plate, and a first bevel gear is fixedly connected to the output end of the third motor. The first bevel gear meshes with the second bevel gear.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. This utility model, by setting up a mobile component and driving the walking wheels to rotate through a third motor, enables the device to move autonomously within the natural gas pipeline. It no longer relies on external traction devices and can move autonomously within the pipeline, reducing dependence on external equipment or personnel and improving the system's independence. Because autonomous movement is achieved, manual operation is reduced, thereby reducing the risk of human error, making cleaning work more precise, and avoiding equipment jamming or damage caused by improper manual adjustment.

[0014] 2. This utility model utilizes a second motor to drive a threaded rod to rotate, causing a moving plate to slide on a limiting rod. The position of the moving component is then adjusted via a first and second connecting rod, allowing the traveling wheels to adapt to pipes of different diameters. This avoids the inconvenience and errors of manual adjustment, making the equipment more flexible in handling diverse pipes. Whether the pipes are large or small diameter, it can operate stably and ensure cleaning efficiency. The equipment can adapt to various pipe types, reducing the need for different pipe cleaning equipment. This compatibility allows for wide application in different environments, eliminating the need to purchase specialized cleaning devices for different pipes and reducing overall costs.

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Reference Figure 1-5 As shown, a cleaning device for natural gas pipeline construction includes an installation sleeve 1. A first motor 2 is fixedly connected to the left side wall inside the installation sleeve 1. The output shaft of the first motor 2 passes through the left side wall of the installation sleeve 1 and is fixedly connected to a rotating disk 3. The rotating disk 3 adopts a quick-release fixed connection method for easy quick replacement. A ring of cleaning bristles 4 is fixedly connected to the outside of the rotating disk 3. The cleaning bristles 4 are configured in a graded manner, with the bristle material being graded as follows: inner layer nylon filaments for removing floating dust, middle layer steel wire bundles for removing rust, and outer layer grinding brushes for polishing the pipe wall. Fixed plates 5 are fixedly connected to both the left and right sides inside the installation sleeve 1. At least three limiting rods 9 are fixedly connected between two fixed plates 5. A movable plate 8 is also provided between two fixed plates 5, and the movable plate 8 is slidably connected to the limiting rods 9. At least three sets of moving components 10 are provided on the outside of the installation sleeve 1. The device can be powered by a battery installed inside the device or by using an external wire. This is existing technology and will not be elaborated on here. It should be noted that if an external wire is selected for power supply, the wire must be of sufficient length and undamaged.

[0024] Specifically, a threaded rod 6 is rotatably connected between the two fixed plates 5 at the middle. The outer surface of the threaded rod 6 is threadedly connected to the middle of the moving plate 8. A second motor 7 for driving the threaded rod 6 to rotate is fixedly installed on the side of the right fixed plate 5. A traction hook 11 is fixedly connected to the middle of the right side of the mounting sleeve 1. The traction hook 11 is used to suspend the traction rope to prevent the device from being unable to detach from the inside of the pipe when it malfunctions. The device can be pulled out by pulling the external rope. Regarding how to prevent impurities and waste from falling on the threaded rod 6 and causing it to jam, a screw rod guard can be used to protect the threaded rod 6. The screw rod guard is an existing product, and its specific principle will not be explained in detail here.

[0025] Specifically, the moving component 10 includes a connecting plate 1001, a first connecting rod 1003 rotatably connected to the middle of the connecting plate 1001, a first connecting ear 1004 rotatably connected to the bottom of the first connecting rod 1003 via a rotating shaft, the first connecting ear 1004 being fixedly connected to the left side of the outer surface of the mounting sleeve 1, and a slot being provided on the mounting sleeve 1 for the passage of the second connecting rod 1005.

[0026] Specifically, the middle part of the first link 1003 is rotatably connected to the second link 1005 via a pivot, and the end of the second link 1005 is rotatably connected to the second connecting ear 1006 via a pivot. The second connecting ear 1006 is fixedly connected to the side of the movable plate 8.

[0027] Specifically, mounting brackets 1002 are fixedly connected to both the front and rear ends of the connecting plate 1001. Rotating rods 1007 are rotatably connected to both sides of the two sets of mounting brackets 1002. The front and rear ends of the rotating rods 1007 pass through the two mounting brackets 1002 respectively and are fixedly connected to the traveling wheels 1008. A traveling belt 1009 is connected between the front and rear traveling wheels 1008. The traveling belt 1009 is made of polyurethane, which is 5 times more wear-resistant than ordinary rubber. The surface is pressed with a herringbone pattern to increase the coefficient of friction and prevent slippage.

[0028] Specifically, a second bevel gear 1013 is fixedly connected to the outer surface of the right rotating rod 1007. A mounting plate 1010 is fixedly connected between the two sets of mounting brackets 1002 near the second bevel gear 1013. A third motor 1011 is fixedly connected to the upper surface of the mounting plate 1010. A first bevel gear 1012 is fixedly connected to the output end of the third motor 1011. The first bevel gear 1012 meshes with the second bevel gear 1013. The speed of the third motor 1011 is controlled by the PLC to realize the differential rotation of the left and right traveling wheels 1008, so that the device automatically turns at the bend and reduces the turning radius.

[0029] Working principle: Place the device at the natural gas pipeline inlet, check if all components are working properly, ensure the power connection is normal, and start the second motor 7. The output shaft of the second motor 7 drives the threaded rod 6 to rotate. Since the middle part of the moving plate 8 is threadedly connected to the threaded rod 6, and the moving plate 8 is slidably connected to the limit rod 9, the moving plate 8 will slide left and right along the limit rod 9 when the threaded rod 6 rotates. The side of the moving plate 8 is connected to the second connecting rod 1005 through the second connecting lug 1006. The second connecting rod 1005 is rotatably connected to the first connecting rod 1003. The bottom of the first connecting rod 1003 is fixed to the left side of the outer surface of the mounting sleeve 1 through the first connecting lug 1004. Therefore, when the moving plate 8 moves, it will drive the second connecting rod 1005 and the first connecting rod 1003 to rotate, thereby causing the connecting plate 1001 to rotate around the first connecting lug 1004. The device moves, and then adjusts the position of the traveling wheels 1008 so that it can adapt to pipes of different diameters. After adjusting the position of the traveling wheels 1008, the third motor 1011 is started. The output end of the third motor 1011 drives the first bevel gear 1012 to rotate. The first bevel gear 1012 meshes with the second bevel gear 1013, which in turn drives the right rotating rod 1007 to rotate. The right rotating rod 1007 drives the left rotating rod 1007 to rotate synchronously through the traveling belt 1009, so that the traveling belt 1009 rolls on the inner wall of the pipe, realizing the autonomous movement of the device in the pipe. At the same time as the device moves, the first motor 2 is started. The output shaft of the first motor 2 drives the rotating disk 3 to rotate. The cleaning bristles 4 on the outside of the rotating disk 3 rotate at high speed to clean the inner wall of the pipe, brushing off the impurities and contaminants on the inner wall of the pipe.
