[0002] A pipeline is a device connected by pipes, pipe connectors, valves, etc. for transporting gases, liquids or fluids with solid particles. When laying pipelines, welding can be used to connect the pipelines. However, after long-term use, cracks may occur in the pipelines, and their airtightness is difficult to guarantee, which is prone to potential safety hazards. Therefore, it is necessary to regularly detect the airtightness of the pipelines to ensure that there is no air leakage
[0003] Most of the existing pipeline airtightness detection devices place the pipelines in a water tank and judge the airtightness of the pipelines by pressurizing the pipelines and observing the bubbles. However, some metal pipelines are not easy to contact water, and during the detection process, it is also necessary to suspend the operation of the pipelines, disassemble and assemble the pipelines, which is cumbersome to operate, requires a large amount of time and manpower, thus reducing the practicability of the airtightness detection device and being inconvenient for the staff to use Summary of the Utility Model
[0004] Aiming at the above-mentioned prior art, the technical problem to be solved by the utility model is that most of the existing airtightness detection devices observe and detect by contacting the pipelines with water. However, some pipelines are not easy to contact water, and during the detection process, it is also necessary to suspend the operation of the pipelines, disassemble and assemble the pipelines, which is cumbersome to operate, requires a large amount of time and manpower, and is inconvenient to use
[0005] To solve the above problems, the utility model provides a hard pipe airtightness detection device for heating ventilation, which includes two accommodating boxes.

It can clamp and fix pipes of different sizes, conduct airtightness detection on the outer surface of the pipes, and can automatically walk on the outer surface of the pipes during detection, so as to detect the whole pipe and improve the detection efficiency.
[0007] As a further improvement of this application, both ends of the mounting rod are fixedly connected to corresponding sections of the two accommodating boxes, and the two fixing rings are fixedly connected by bolts.

Specific embodiments
[0021] The following will make a detailed description of the two embodiments of the present application with reference to the accompanying drawings.
[0022] The first embodiment:
[0023] Figure 1 , Figure 2 and Figure 3Shown: A hermeticity detection device for a warm - use rigid pipeline, including two accommodation boxes 1. A cylinder 2 is fixedly connected to the inner bottom wall of the accommodation box 1. Two fixed rods 3 are fixedly connected to the inner wall of the accommodation box 1. An adjustment cylinder 4 is rotatably sleeved on the outer surface of the fixed rod 3. An adjustment plate 5 and a clamping plate 6 are fixedly connected to the outer surface of the adjustment cylinder 4. The adjustment plate 5 is located inside the accommodation box 1. Both the adjustment plate 5 and the clamping plate 6 are arc - shaped, and the bending directions of the adjustment plate 5 and the clamping plate 6 are opposite. Two positioning rods 7 are fixedly connected to the outer surface of the cylinder 2. One end of the positioning rod 7 far from the cylinder 2 is fixedly connected to a push cylinder 8. The outer surface of the push cylinder 8 is in contact with the outer surface of the adjustment plate 5. The extension of the cylinder 2 can drive the movement of the positioning rod 7 and the push cylinder 8, so that the push cylinder 8 pushes the adjustment plate 5, causing the adjustment plate 5 to rotate to both sides with the adjustment cylinder 4 as the center, and the clamping plate 6 rotates inward with the adjustment cylinder 4 as the center, so that the two clamping plates 6 clamp both sides of the outer surface of the pipeline, making the device applicable to pipelines of different sizes and improving the practicability of the device. An installation block one 9 is fixedly connected to the upper end of the cylinder 2 and one end of the clamping plate 6 far from the adjustment cylinder 4. An electric rotating rod 10 is rotatably connected inside the installation block one 9. Those skilled in the art can select an appropriate model of the electric rotating rod 10 according to actual needs. For example: JCW - 0001. A clamping roller 11 is fixedly sleeved on the outer surface of the electric rotating rod 10. The rotation of the electric rotating rod 10 can drive the clamping roller 11 to rotate, so that multiple clamping rollers 11 roll on the outer surface of the pipeline, thereby driving the device to move. Both the front and rear ends of the accommodation box 1 are isosceles trapezoids, which is convenient for the adjustment plate 5 to rotate. A rubber sleeve is fixedly sleeved on the outer surface of the clamping roller 11 to increase the friction between the clamping roller 11 and the pipeline.
[0024] Figure 4 Shown: At one end corresponding to the two accommodation boxes 1, there is an installation rod 12. A positioning block 13 is fixedly sleeved on the outer surface of the installation rod 12. An installation block two 14 is fixedly connected to the upper end of the positioning block 13. Two fixed rings 15 are rotatably connected inside the installation block two 14. A plurality of ultrasonic probes 16 are fixedly connected to the inner ring surface of the fixed rings 15. The plurality of ultrasonic probes 16 can detect and detect flaws on the outer surface of the pipeline. Both ends of the installation rod 12 are fixedly connected to corresponding sections of the two accommodation boxes 1. The two fixed rings 15 are fixedly connected by bolts, which is convenient for the staff to open and close the two fixed rings 15.
[0025] During use, place the accommodating box 1 at the lower end of the pipeline. Start the cylinder 2 to extend, so that the clamping roller 11 at the upper end of the cylinder 2 contacts the outer surface of the pipeline. At the same time, the extension of the cylinder 2 drives the push cylinder 8 to move, causing the push cylinder 8 to push the adjusting plate 5 to rotate outward on both sides with the adjusting cylinder 4 as the center, and the clamping plate 6 rotates inward with the adjusting cylinder 4 as the center, so that the clamping rollers 11 on the clamping plate 6 clamp and fix both sides of the outer surface of the pipeline, thereby clamping pipelines of different sizes. Then close the two fixing rings 15 and fix them with bolts. Multiple electric rotating rods 10 rotate, driving the clamping rollers 11 to rotate, so that the device moves on the outer wall of the pipeline. During the movement, the outer surface of the pipeline is detected by the ultrasonic probe 16. There is no need for staff to pause and disassemble the pipeline to detect the whole pipeline, thus improving the detection efficiency.
[0026] The second implementation mode:
[0027] Based on the first implementation mode, this implementation mode adds a fixing box 17, a limiting hole 18 and a screw rod 19, and the rest is the same as the first implementation mode.
[0028] Figure 5 and Figure 6 Shown: Fixing boxes 17 are fixedly connected to the corresponding ends of the two accommodating boxes 1. Both ends of the mounting rod 12 are slidably connected to the inner cavity of the adjacent fixing box 17 respectively, so as to adjust the height of the mounting rod 12, making the pipeline located in the middle of the fixing ring 15. Multiple limiting holes 18 are drilled at the front end of the fixing box 17. A screw rod 19 is provided at the front end of the fixing box 17. The rear end of the screw rod 19 sequentially passes through the adjacent limiting hole 18 and the mounting rod 12 in a threaded manner. The screw rod 19 can fix the mounting rod 12 and the fixing box 17, thereby improving the stability of the mounting rod 12.
[0029] During use, the height of the mounting rod 12 can be moved up and down, so that the pipeline is located in the middle of the two fixing rings 15. Then, the screw rod 19 passes through the limiting hole 18 and the mounting rod 12 to fix the mounting rod 12 and the fixing box 17, thereby improving the stability of the mounting rod 12.
[0030] Combined with the current actual requirements, the above implementation modes adopted by this application, the scope of protection is not limited to this. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
