[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid flows from the high pressure part of the pipeline to the low pressure part after being pressurized by blowers, compressors, pumps and boilers. It can also be conveyed by the fluid's own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices.

[0044] Specifically, the driving wheel 5 and the first screw shaft 6 are connected by a coupling, so that the rotational power of the driving wheel 5 can be effectively transmitted to the first screw shaft 6. When the driving wheel 5 rotates, it can simultaneously drive the rotation of the first screw shaft 6 and the second screw shaft 9. Moreover, the first slider 10 and the second slider 11 are arranged on the same side, so that the X-ray emitter 12 on the first slider 10 can transmit the ray signal to the detector 13 on the second slider 11, thereby measuring the inner diameter thickness of the pipeline. Moreover, the detection area is set to provide a movable space for the pipeline to pass through, so as to avoid interference between structural parts.

[0045] An endoscopy detection mechanism 2 is provided. After the servo motor 3 is started, it can drive the rotation of the first screw shaft 6, and through the transmission action of the first conveyor belt 8, drive the second screw shaft 9 to rotate in the same direction, so that the first slider 10 and the second slider 11 can drive the corresponding X-ray emitter 12 and the detector 13 to move synchronously inside and outside the pipeline, so that the X-ray principle can be used to effectively measure the overall inner diameter thickness of the pipeline, and the transmission parts have strong synchronization performance, ensuring accurate docking between the X-ray emitter 12 and the detector 13, and good working stability.

[0046] refer to Figure 1 , Figure 5 and Figure 6, the pipeline cleaning mechanism includes a fixed block 14 installed at one end of the first screw shaft 6, and both sides of the fixed block 14 are connected to rotating blades 16 placed on the first slider 10 through telescopic rods 15. The telescopic rods 15 are multi-node settings, one end of the rotating blade 16 is connected to the first slider 10 through a rotating ring 17, and one end of the telescopic rod 15 penetrates the rotating blade 16 and extends to the scraper 19 on the outer wall of the filter screen 18.

[0047] A pipeline cleaning mechanism is provided. During the rotation of the first screw shaft 6, the fixed block 14 can be driven to rotate synchronously. Since the first slider 10 moves in the horizontal direction, during the rotation of the fixed block 14, the telescopic rod 15 can drive the scraper 19 and the rotating blade 16 on the first slider 10 to rotate together. Moreover, the telescopic rod 15 is provided with multiple nodes, which can ensure the normal horizontal movement of the first slider 10. Moreover, the rotating blade 16 can remove the garbage in the pipeline by blowing, and the bristles on the scraper 19 can further improve the cleanliness of the inner wall of the pipeline to prevent foreign particles from affecting the accuracy of the thickness measurement. The rotating ring 17 on the rotating blade 16 and the annular groove on the scraper 19 can effectively prevent the cleaning member from deviating from its position during the activity, thereby effectively removing the garbage and particulate impurities while ensuring the stability of the rotating member.

[0048] In order to prevent the garbage inside the pipeline from affecting the normal detection work, a pipeline cleaning mechanism is provided at the front end of the endoscopic detection equipment. When the first screw shaft 6 rotates, it can drive the synchronous rotation of the fixed block 14. The fixed block 14 can drive the rotating blades 16 and the scraper 19 to rotate together through the telescopic rod 15. In this way, when the first slider 10 rotates normally, the rotating blades 16 and the scraper 19 can also ensure the free horizontal movement of the first slider 10. The rotating blades 16 remove the garbage by wind sweeping, and the bristles on the scraper 19 can further remove impurities on the inner wall of the pipeline. The filter 18 on the scraper 19 can prevent the garbage from contacting the endoscopic detection mechanism 2, thereby preventing the normal operation of the X-ray emitter 12, and the scraper 19 can remove the impurities on the filter 18 during the rotation process, and can be discharged in the pipeline in cooperation with the rotating blades 16.

[0049] refer to Figure 2 , Figure 4 , Figure 7 and Figure 8The endoscopic inspection equipment for pipeline quality inspection also includes a garbage pressing mechanism 20, which includes a corrugated hose 21. One end of the corrugated hose 21 is equipped with a material guide port connected to the pipeline opening, and the other end is equipped with a conduit fixed on the air pump 22. One end of the conduit passes through the box and extends to the inside of the box. The top of the first bevel gear 4 is meshed with a second bevel gear 24 fixed on the rotating wheel 23.

[0050] The rotating wheel 23 and the rotating shaft 25 are connected through a second conveyor belt 26. A reciprocating screw 27 is fixedly installed at the bottom of the rotating shaft 25. A third slider 28 is spirally driven on the reciprocating screw 27. A pressure plate 29 placed on the inner wall of the box is connected to the extended end of the third slider 28, and the third slider 28 has a strip groove along the height direction of the side wall of the box. A driving motor 30 is fixedly installed at the center of the bottom of the box. The output shaft of the driving motor 30 passes through the box and is connected to a cutting knife 32 through a telescopic component 31.

[0051] The telescopic assembly 31 includes a first sleeve 33 fixed on the cutting knife 32, the first sleeve 33 is movably connected to the groove of the side wall of the second sleeve 34, and both ends of the first sleeve 33 are integrally formed with protrusions 35, and the inner wall of the second sleeve 34 is provided with an embedding groove connected to the protrusion 35 in the height direction, the bottom of the first sleeve 33 and the inner wall of the second sleeve 34 are connected by a spring rod 36, and a storage cavity 37 connected to the cutting knife 32 is provided inside the box.

[0052] Specifically, when the servo motor 3 rotates, it can transmit power to the rotating wheel 23 on the second bevel gear 24 through the first bevel gear 4, and make the rotating wheel 23 rotate, so that under the transmission action of the second conveyor belt 26, the vertical reciprocating screw 27 can be rotated, and during the up and down movement of the pressure plate 29, the garbage sucked into the box can be pressed and compressed, and the cutting knife 32 in the box can be crushed first, so as to facilitate effective compression work.

[0053] In addition, the telescopic component 31 cooperates with the storage cavity 37 in the box body to not only ensure the flatness of the garbage processing when the pressure plate 29 moves, but also can drive the normal rotation and cutting work of the cutting knife 32 through the telescopic component 31, thereby ensuring the effective crushing of the garbage, ensuring that the cutting knife 32 can move up and down freely, and can also allow it to perform rotational cutting.

[0054] A garbage pressing mechanism 20 and a telescopic component 31 are provided. When the air pump 22 sucks the garbage into the box, the driving motor 30 is started and drives the cutting knife 32 to rotate and cut, thereby crushing the garbage. In conjunction with the pressing plate 29 on the reciprocating screw 27, the garbage can be pressed during the up and down movement of the pressing plate 29, thereby compressing it and avoiding occupying too much space resources. In addition, in order to ensure the flatness requirements of the garbage during the pressing process, the telescopic component 31 can be used to press the cutting knife 32 into the storage cavity 37 during the downward movement of the pressing plate 29, thereby improving the ability to press the garbage well.

[0055] Specifically, a pushing cylinder 38 is installed on the workbench 1, one end of the piston rod on the pushing cylinder 38 extends to the servo motor 3 and the cover body, and the piston rod and the fourth slider 39 are connected by a swing rod 40, and the top of the fourth slider 39 is movably connected to a tensioning wheel 42 placed on the second conveyor belt 26 through a pushing rod 41, and both ends of the swing rod 40 are connected to the piston rod and the fourth slider 39 by a rotating connection. The servo motor 3 and the bottom of the cover body are both provided with sliding guide rails placed on the workbench 1.

[0056] A tensioning adjustment component is provided. Under the action of the pushing cylinder 38, the endoscope detection mechanism 2 can be stored in the workbench 1. Since the rotating wheel 23 and the rotating shaft 25 are connected by the second conveyor belt 26, when the endoscope detection mechanism 2 moves toward the center of the workbench 1, the second conveyor belt 26 becomes loose. At this time, the tensioning wheel 42 connected by the fourth slider 39 is tensioned and adjusted to ensure the tightness of the second conveyor belt 26. The power can be effectively transmitted, so that when the endoscope detection mechanism 2 is stored, the transmission member is tensioned and adjusted accordingly, thereby ensuring the normal operation of the equipment.

[0057] refer to Fig. 9 , the pipeline quality inspection using endoscopic inspection method, including the following steps:

[0058] S1.1, the push cylinder 38 is started, and the servo motor 3 and the cover body are driven to move toward the outside of the workbench 1, and the first screw shaft 6 and the second screw shaft 9 are respectively inserted into the inner and outer sides of the pipeline, and at the same time, the tensioning wheel 42 is driven to move toward the center of the workbench 1 and the tension of the second conveyor belt 26 is adjusted;

[0059] S1.2, the servo motor 3 is started, the first slider 10 and the second slider 11 on the first screw shaft 6 and the second screw shaft 9 move synchronously, and the pipeline thickness detection work is completed through the X-ray emitter 12 and the detector 13;

[0060] S1.3, after the servo motor 3 of step S1.2 is started, the fixed block 14 rotates synchronously, and drives the rotating blade 16 and the scraper 19 to rotate on the first slider 10, and can perform air blowing and cleaning work on the inside of the pipeline during the rotation;

[0061] S1.4. Under the action of the air pump 22, the garbage inside the pipe is absorbed into the box. Under the action of mechanical transmission, the driving motor 30 drives the cutting knife 32 to crush the garbage, and then the third slider 28 drives the pressing plate 29 to press the garbage.

[0062] The X-ray thickness gauge measures the thickness of the material by using the property that the change in the intensity of the X-rays is related to the thickness of the material when the X-rays penetrate the material. It is a non-contact dynamic measuring instrument. The X-ray thickness gauge can be automatically controlled to ensure that the thickness of the plate meets the requirements. The X-ray emission source emits X-rays, which penetrate the material and are received by the detector 13. By measuring the transmission intensity, the thickness of the material can be calculated.

[0063] The entire detection process has a high degree of automation and strong integration performance. It can accurately measure the thickness of the inner wall of the pipeline, improve the accuracy of the detection data, facilitate personnel operation, and compress the garbage inside the pipeline, which is conducive to resource recycling, avoiding resource waste and protecting the environment.
