[0002] Pipelines are devices connected by pipes, pipe connectors, and valves for transporting gases, liquids, or fluids containing solid particles. Pipelines are widely used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations. During use, pipelines are inevitably damaged due to natural causes such as aging and corrosion, or due to human factors.

[0003] Pipelines used to transport saline-alkali saturated solutions need to be inspected regularly to avoid leakage of saline-alkali saturated solutions caused by pipeline leakage. The existing pipeline leakage positioning method is generally through manual inspection and regular inspection to locate pipeline leakage, but manual inspection can only detect the surface of the pipeline. Part of the pipeline will be buried inside the soil. When inspecting the pipeline, it is necessary to break the soil, which is very troublesome.

[0021] A plurality of rubber belts are provided on the surface of the concave hole block.

[0022] Furthermore, the extrusion sheet is elastically arranged, the top of the rubber belt is arranged at the top outer end of the concave hole block, and the movable frame is in contact with the surface of the bottom rod.

[0023] The present invention has the beneficial effects:

[0024] The cylindrical frame of the present invention moves toward the interior of the pipeline, and the cylindrical frame pushes the ball to slide inside the pipeline through the driver. The contact between the ball and the inner wall of the pipeline is used to improve the smooth movement of the cylindrical frame inside the pipeline. A cleaning component is provided on the left side of the cylindrical frame, and the interior of the pipeline is cleaned by the cleaning component to prevent impurities inside the pipeline from adhering to the inner wall of the pipeline, resulting in the camera being unable to clearly capture the situation of the pipeline temporal part. A lighting lamp is provided on the surface of the mounting frame, and the lighting lamp assists the camera to shoot the situation inside the pipeline, so as to quickly find the leakage location of the pipeline.

[0025] After the cylindrical frame of the present invention enters the interior of the pipeline, the motor is passed, and the meshing frame pushes the annular tooth frame to rotate through the rotating rod. The annular frame pushes the arc scraper to rotate through the rotation of the annular tooth frame. The arc scraper cleans and scrapes the inner wall of the pipeline during rotation to prevent impurities from adhering to the inner wall of the pipeline, causing impurities to seal the leakage of the pipeline and cannot be quickly discovered. After the electric push rod is started, it pushes the slider to move toward the outer end of the slide, and the distance of the arc scraper is adjusted by the slider so that the arc scraper can adapt to pipelines of different thicknesses. The arc scraper can be adjusted by pulling the triangular movable rod during adjustment, further increasing the stability of the arc scraper during operation.

[0026] The present invention clamps and fixes the rubber block through the groove on the surface of the arc scraper. The volume of the rubber block is larger than the inner wall of the groove, so as to increase the stability of the rubber block inside the groove. The rubber block extends out of the surface of the arc scraper. When the arc scraper cleans the inner wall of the pipe, the rubber block will contact the inner wall of the pipe, so as to prevent the arc scraper from hitting the inner wall of the pipe. The stability of the rubber block is improved by squeezing the block. The rubber block is plugged into the arc scraper through the groove so that the rubber block can be replaced.

[0027] When the cylindrical frame is placed inside the pipe, the distance between the rolling ball and the inner wall of the pipe needs to be adjusted. The twisting adjustment frame drives the connecting rod to rotate on the surface of the cylindrical frame, and the connecting rod pushes the threaded frame to rotate on the surface of the threaded plate. The threaded plate moves upward through the threaded connection with the threaded frame. The extension rod pushes the rolling ball closer to the inside of the pipe through the upward movement of the threaded plate, so as to increase the stability of the cylindrical frame in the movement inside the pipe.

[0028] When the extension rod of the present invention moves upward, it pulls the moving frame upward through the connecting rod, and the extrusion sheet pushes the concave hole block upward so that the rubber belt contacts the inner wall of the pipe. When the cylindrical frame moves, it pushes the rubber belt to rotate inside the concave hole. When the motor pushes the ring frame to rotate, the movement trajectory of the rubber belt is consistent with that of the cylindrical frame. When the ring frame rotates, the friction between the rubber belt and the inner wall of the pipe is increased through the rubber belt, thereby preventing the ring frame from pushing the cylindrical frame to cause shaking or flipping, resulting in poor cleaning effect and failure to timely discover pipeline leaks.

[0059] A plurality of rubber belts 72 are provided on the surface of the recessed block 73 .

[0060] The extrusion sheet 71 is elastically arranged, the top of the rubber belt 72 is arranged at the top outer end of the concave hole block 73, and the movable frame 70 contacts the surface of the bottom rod 65.

[0061] A specific application of this embodiment is as follows: the cylindrical frame 2 moves toward the inside of the pipe 1, and the cylindrical frame 2 pushes the ball to slide inside the pipe 1 through the driver 4, and the contact between the ball and the inner wall of the pipe 1 is used to improve the smooth movement of the cylindrical frame 2 inside the pipe 1. A cleaning component 3 is provided on the left side of the cylindrical frame 2, and the inside of the pipe 1 is cleaned by the cleaning component 3 to prevent impurities inside the pipe 1 from adhering to the inner wall of the pipe 1, resulting in the camera 7 not being able to clearly capture the situation of the pipe 1. A lighting lamp 8 is provided on the surface of the mounting frame 9, and the lighting lamp 8 assists the camera 7 to shoot the situation inside the pipe 1, so as to quickly find the leakage position of the pipe 1. After the cylindrical frame 2 enters the interior of the pipe 1, the motor 44 passes, and the engaging frame 43 passes. The rotating rod 41 pushes the annular tooth frame 42 to rotate, and the annular frame 20 pushes the arc scraper 21 to rotate through the rotation of the annular tooth frame 42. The arc scraper 21 cleans and scrapes the inner wall of the pipe 1 when rotating to prevent impurities from adhering to the inner wall of the pipe 1, causing impurities to seal the leakage of the pipe 1 and cannot be quickly discovered. After the electric push rod 26 is started, it pushes the slider 28 to move toward the outer end of the slide 25. The distance of the arc scraper 21 is adjusted by the slider 28 so that the arc scraper 21 can adapt to pipes of different thicknesses. The arc scraper 21 can be adjusted by pulling the triangular movable rod 24 to further increase the stability of the arc scraper 21 during work. The rubber block 50 is clamped and fixed by the card groove 51 on the surface of the arc scraper 21. The volume of the rubber block 50 is larger than the inner wall of the card slot 51 to increase the stability of the rubber block 50 inside the card slot 51. The rubber block 50 extends out of the surface of the arc scraper 21. When the arc scraper 21 cleans the inner wall of the pipe 1, the rubber block 50 will contact the inner wall of the pipe 1 to prevent the arc scraper 21 from hitting the inner wall of the pipe 1. The stability of the rubber block 50 is improved by squeezing the block 52. The rubber block 50 is plugged into the arc scraper 21 through the card slot 51 so that the rubber block 50 can be replaced. When the cylindrical frame 2 is placed inside the pipe 1, the distance between the ball 63 and the inner wall of the pipe 1 needs to be adjusted. The twisting adjustment frame 60 drives the connecting rod 61 to rotate on the surface of the cylindrical frame 2, and the connecting rod 61 drives the threaded frame 69 to rotate on the surface of the threaded plate 62 The threaded plate 62 moves upward by being threadedly connected with the threaded frame 69, and the extension rod 64 pushes the ball 63 close to the inside of the pipe 1 through the upward movement of the threaded plate 62, so as to increase the stability of the cylindrical frame 2 moving inside the pipe 1. When the extension rod 64 moves upward, it pulls the movable frame 70 upward through the connecting rod 74, and the extrusion piece 71 pushes the concave hole block 73 to move upward so that the rubber belt 72 contacts the inner wall of the pipe 1. When the cylindrical frame 2 moves, it pushes the rubber belt 72 to rotate inside the concave hole. When the motor 44 pushes the circular frame 20 to rotate, the movement trajectory of the rubber belt 72 is consistent with that of the cylindrical frame 2. When the circular frame 20 rotates, the rubber belt 72 increases the friction with the inner wall of the pipe 1 through the rubber belt 72, so as to prevent the circular frame 20 from pushing the cylindrical frame 2 to shake or flip.This results in poor cleaning results and failure to promptly discover the leak in pipeline 1.
