Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection equipment technology, and more specifically, to an online intelligent inspection device for composite pipes. Background Technology

[0002] Composite pipes are widely used in fluid transportation. However, prolonged fluid transportation can easily lead to fluid leakage risks in composite pipes, especially at pipe joints, where leaks often occur due to the following reasons:

[0003] (1) Improper installation: The connector was not properly aligned, fixed, or sealed during installation, resulting in gaps or incomplete seals at the interface. This may be due to improper surface cleaning, uneven or inappropriate application of sealant, or insufficient torque during tightening.

[0004] (2) Damaged seals: The seals at the joint (such as O-rings, gaskets, etc.) are damaged or aged, losing their original sealing performance. This may be due to material quality issues, aging caused by long-term use, or damage during installation.

[0005] (3) Improper material selection: If the selected sealing material is incompatible with the pipe material or unsuitable for specific working environment conditions, leakage at the joint may occur. For example, for certain chemical media, the corrosion resistance and wear resistance of the sealing material are very important.

[0006] (4) Pressure or temperature changes: During pipeline operation, due to periodic changes in pressure or temperature, slight movement or deformation may occur at the joint, which may lead to the destruction of the original normal sealing state and thus cause leakage problems.

[0007] (5) Pipeline vibration or shock: If there is significant vibration or shock during pipeline operation, it may cause the fasteners or seals at the joints to loosen, resulting in leakage.

[0008] (6) Pipe material fatigue: After long-term use, the pipe material may undergo fatigue deformation or aging, which will lead to a decrease in the structural performance and sealing performance of the joints, resulting in leakage.

[0009] In summary, the causes of leakage at composite pipe joints can be multifaceted. If a leak occurs and is not detected and stopped in time, it can easily lead to personal safety accidents.

[0010] Currently, operators typically need to regularly inspect composite pipes to check for loose joints, aging seals, and other issues to ensure long-term stable operation. However, this process is not only labor-intensive but also prone to omissions, and despite its time and effort, it does not significantly reduce the probability of risks. Utility Model Content

[0034] Example 1 (in conjunction with the appendix) Figure 1-4 The present invention will be further described as follows:

[0035] This utility model provides an online intelligent testing device 10 for composite pipes. Please refer to [link / reference]. Figure 1-4 The online intelligent testing equipment 10 for composite pipes includes multiple spliced ​​pipes 200 connected by flanges 100, multiple sets of sealing components 300 correspondingly set at the connection of two adjacent spliced ​​pipes 200, and a testing component 400.

[0036] The sealing assembly 300 includes a first connector 310, a second connector 320, a first sealing ring 330, a first fixing ring 340 fixedly sleeved and connected to the splicing pipe 200, a second fixing ring 350 fixedly sleeved and connected to an adjacent splicing pipe 200, a second sealing ring 360 fitted to the first fixing ring 340, a third sealing ring 370 fitted to the second fixing ring 350, and a connecting assembly 380.

[0037] In this embodiment, one end of the first connector 310 is slidably connected to the outer wall of the splicing pipe 200 along its circumference, and one end of the second connector 320 is slidably connected to the outer wall of the adjacent splicing pipe 200 along its circumference. The other end of the first connector 310 is detachably connected to the other end of the second connector 320. A first sealing ring 330 is disposed at the connection between the first connector 310 and the second connector 320, forming a receiving space 500 for accommodating the flange 100 between the first connector 310 and the second connector 320.

[0038] Specifically, the end of the first connector 310 furthest from the splicing pipe 200 is connected to a first connecting section 311, and the end of the second connector 320 furthest from the splicing pipe 200 is connected to a second connecting section 321. Both the first connecting section 311 and the second connecting section 321 have annular cross-sections along a direction perpendicular to the axis of the splicing pipe 200. The inner diameter of the first connecting section 311 is smaller than the inner diameter of the second connecting section 321. A sealing ring is disposed between the first connecting section 311 and the second connecting section 321.

[0039] The connecting assembly 380 includes a first connecting ring 381 and a second connecting ring 382. The first connecting ring 381 is sleeved on the first connecting segment 311, and the second connecting ring 382 is sleeved on the end of the second connecting segment 321 away from the second connecting member 320. The first connecting ring 381 and the second connecting ring 382 are detachably connected. The first connecting ring 381 and the second connecting ring 382 are bolted together.

[0040] When the first connector 310 is connected to the second connector 320, the first connector 310 abuts against the second sealing ring 360, and the second connector 320 abuts against the third connecting ring. In this embodiment, the detection assembly 400 includes a plurality of sensors 410 and GPS locators 420 disposed one by one within the accommodating space 500, and a processor 430, a controller 440, an alarm 450, and a human-machine interface 460 disposed outside the splicing pipe 200. The sensors 410 are disposed at the lowest position in the accommodating space 500. The sensors 410 can be selected as pressure sensors, acoustic sensors, gas sensors, temperature sensors, etc., according to the fluid properties. The sensors 410 and GPS locators 420 are electrically connected to the processor 430, the processor 430 is electrically connected to the controller 440, the controller 440 is electrically connected to the alarm 450, and the human-machine interface 460 is electrically connected to the controller 440.

[0041] The online intelligent testing device 10 for composite pipes provided in this embodiment works as follows: two adjacent spliced ​​pipes 200 are connected together, and flanges 100 are connected. The first connecting piece 310 and the second connecting piece 320 are pushed to approach the first fixing ring 340 and the second fixing ring 350 respectively. As the first connecting piece 310 and the second connecting piece 320 approach each other, the first connecting segment 311 is inserted into the second connecting segment 321 until it abuts against the second connecting piece 320. The first connecting ring 381 and the second connecting ring 382 are bolted and fixed. At this time, the first connecting piece 310 abuts against the second sealing ring 360, the second connecting piece 320 abuts against the third sealing ring 370, and the first connecting segment 311 abuts against the first sealing ring 330. A sealed receiving space 500 is formed between the first connecting piece 310 and the second connecting piece 320.

[0042] If fluid leaks from the flange 100 connection during the operation of the pipeline, the leaked fluid enters the containment space 500. The sensor 410 senses the change and transmits the signal to the processor 430, and at the same time activates the positioning signal. The processor 430 transmits the signal to the controller 440, and the alarm 450 then sounds an alarm. The staff can then perform further operations on the human-machine interface 460.

[0043] In summary, the online intelligent detection device 10 for composite pipes provided in this embodiment has an ingenious structural design. It can monitor and automatically detect whether there is a leak in the composite pipe in real time and locate the specific location of the leak. It plays a role in rapid detection, accurate positioning, and timely warning to stop losses. It can also recover leaked fluid, avoid expanding the leak range, and greatly reduce the probability of risk occurrence. Moreover, it can facilitate disassembly and inspection, and timely repair of the composite pipe.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
