Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4This utility model discloses a pipeline engineering inspection device, comprising a base plate 1, a fixed box 2 at one end of the top surface of the base plate 1, an exhaust fan 3 installed on one side of the top surface of the fixed box 2, a foam box 4 on one side of the exhaust fan 3, two symmetrical mounting slots on both sides of the bottom surface of the fixed box 2, each slot containing a lead screw 7 rotatably mounted, a support seat 5 sleeved on the two lead screws 7, and a sliding box sleeved on one side of the two lead screws 7 at the support seat 5, with a fixed cover on the opposite surface of the sliding box and the fixed box 2; a second motor 12, model MGM132-4; ​​this structure, through the cooperation of the second motor 12, the driving gear 13, the driven gear 14 and the lead screw 7, facilitates quick and automatic adjustment of the position of the support seat 5 and the sliding box, improving installation efficiency and enabling rapid fixing of pipes of different diameters; a rotating cover 11 is rotatably mounted on one side of the fixed box 2, a first motor 9 is installed in the middle of the top surface of the fixed box 2, and a driven pulley rotatably mounted inside the fixed box 2 is coaxially fixed to one end of the rotating cover 11. A drive pulley is coaxially fixed to the output shaft of motor 9, and a belt 10 is installed between the driven pulley and the drive pulley. The first motor 9 is model Y2-132M-4. Through the cooperation of the first motor 9, the drive pulley, the belt 10 and the driven pulley, the rotating cover 11 is easily driven to rotate automatically, which improves the automation level of the inspection and enables all-round inspection of the pipeline, thus improving the inspection efficiency. Rubber gaskets 8 are attached to the inner walls of both the fixed cover and the rotating cover 11. A fixed platform is fixed to the top surface of the base plate 1 on one side of the fixed box 2. Both the fixed platform and the support base 5 are equipped with arc-shaped brackets coaxial with the rotating cover 11. Multiple rotating shafts 6 are equidistantly mounted on the arc surface of the arc-shaped bracket along the axial side. The rubber gaskets 8 are made of nitrile rubber. The arc-shaped brackets and rotating shafts 6 are made of 45# steel. The rubber gaskets 8 cooperate with the pipeline to enhance the sealing effect and prevent air and water leakage during inspection. The arc-shaped brackets and rotating shafts 6 cooperate to stably support the pipeline and reduce friction, improving the adaptability of the device to pipelines of different diameters.

[0020] In this invention, a second motor 12 is mounted on one end of the base plate 1. A drive gear 13 is coaxially fixed to the output shaft of the second motor 12. Driven gears 14 mesh with both sides of the drive gear 13. The driven gears 14 are coaxially fixed to one end of the lead screw 7. A dust cover is provided on the base plate 1 at the driven gears 14 and the drive gear 13. The drive gears 13 and 14 are made of 20CrMnTi carburized steel. This structure further ensures the stability of the lead screw 7 transmission and ensures the reliability of the device for fixing pipes of different diameters. An airtight cylinder 15 is provided in the middle of the top surface of the sliding box. A sealing cover is screwed to the top of the airtight cylinder 15. A pressure sensor 18 is provided on the top surface inside the sealing cover. A spring 19 is provided inside the airtight cylinder 15. One end of the spring 19 abuts against the pressure sensor 18. A telescopic rod 17 is sleeved on the other end of the spring 19. A sealing block 16 is fixed to one end of the telescopic rod 17. The bottom end of spring 19 abuts against the top surface of sealing block 16; pressure sensor 18 is model Huba511.9; spring 19 is made of 65Mn spring steel; through the cooperation of pressure sensor 18, spring 19, telescopic rod 17 and sealing block 16, it is convenient to monitor the pressure change inside the pipeline in real time and accurately, improve the detection sensitivity, and thus be able to detect minor defects; the bottom end of airtight cylinder 15 is connected to fixed cover, and exhaust fan 3 and foam box 4 are both connected to rotating cover 11 through pipes. Both fixed cover and rotating cover 11 are horn-shaped; exhaust fan 3 is model DF-11-7A; exhaust fan 3 draws gas containing foam from foam box 4 and sends it into rotating cover 11 and pipeline. If there is a leak in the pipeline, foam will accumulate at the leak point to generate bubbles. Combined with the real-time monitoring of pressure changes by pressure sensor 18 in airtight cylinder 15, the airtightness of the pipeline and the presence of defects are determined.

[0021] Working principle: When using this utility model, the pipeline to be tested is placed on the arc-shaped bracket of the fixed platform and support base 5. The rotating shaft 6 on the arc-shaped bracket contacts the pipeline. The second motor 12 at one end of the base plate 1 is started, and its output shaft drives the drive gear 13 to rotate. The drive gear 13 meshes with the driven gears 14 on both sides. The driven gears 14 are coaxially fixed to the lead screw 7, driving the lead screw 7 to rotate. This causes the support base 5 and the sliding box sleeved on the lead screw 7 to move, adjusting the fixed cover and the rotating cover 11 to a suitable position to cover the pipeline. The rubber gaskets 8 on the inner walls of the fixed cover and the rotating cover 11 are tightly fitted to the pipeline to achieve a seal. The first motor 9 in the middle of the top surface of the fixed box 2 is turned on. The drive pulley on its output shaft drives the driven pulley to rotate through the belt 10. The driven pulley is coaxially fixed to the rotating cover 11, causing the rotating cover 11 to rotate and drive the pipeline to rotate. Start the exhaust fan 3. The exhaust fan 3 draws out the foam-containing gas from the foam box 4 and sends it into the rotating cover 11 through the pipeline, thus filling the pipeline. If there is a leak in the pipeline, the foam will accumulate at the leak point and generate bubbles. The bottom end of the airtight cylinder 15 in the middle of the top surface of the sliding box is connected to the fixed cover. When the pipeline is under normal air pressure, the pressure acts on the sealing block 16, compresses the spring 19, and the telescopic rod 17 moves upward, causing the pressure sensor 18 to sense the pressure change. When the pipeline malfunctions and the internal pressure decreases, the spring 19 relaxes and pushes the sealing block 16, the telescopic rod 17 moves downward, and the pressure sensor 18 senses the pressure decrease. By monitoring the pressure change in real time through the pressure sensor 18, combined with the situation of foam generating bubbles, the airtightness of the pipeline and the presence of defects are determined. At this point, the device is in use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
