For example, in the water supply and drainage sector, they are used to transport tap water and discharge sewage; in the oil and gas industry, they transport energy sources such as crude oil and natural gas; and in the chemical industry, they transport various chemical products. Pipelines are an indispensable infrastructure in modern industry and life, and their safe and efficient operation is of great significance to ensuring the normal operation of production and life. However, when using pipelines, it is necessary to test their corrosion resistance using testing equipment.

[0003] Pipeline corrosion resistance testing devices are important equipment used to assess the corrosion resistance of pipeline materials in specific environments. These testing devices typically employ a variety of technologies and methods for precise measurement and analysis. In practical applications, such as in the petrochemical industry, for pipelines transporting corrosive media, regular use of corrosion resistance testing devices can detect potential corrosion problems in advance and prevent leakage accidents. Pipeline corrosion resistance testing devices play an extremely important role in ensuring the safe and reliable operation of pipelines and preventing corrosion-related failures and accidents.

[0004] However, traditional pipeline corrosion resistance testing devices are difficult to use to effectively fix the pipeline, which can easily cause the pipeline to shift in position and affect the accuracy of the pipeline corrosion resistance test results. Therefore, a new pipeline corrosion resistance testing device is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pipeline corrosion resistance testing device includes a housing, inside which are arranged multiple fixed supports. Each fixed support contains an electrically operated telescopic rod. The output end of each electrically operated telescopic rod is fixedly connected to a connecting column. A connecting block is fixedly connected to one side of each electrically operated telescopic rod. Connecting rods are rotatably connected to the connecting columns and connecting blocks. Connecting rods are fixedly connected to one side of each connecting rod. Connecting rods are rotatably connected to the connecting rods. Connecting rings are rotatably connected to the inner walls of the connecting rings. Connecting blocks are rotatably connected to the connecting rods. Connecting rods are rotatably connected to the connecting rods. Clamping plates are rotatably connected to the connecting rods. A pipeline body is arranged between the clamping plates. A testing component is arranged inside the pipeline body. The testing component is used to test the corrosion resistance of the pipeline body.

[0023] 1. In this utility model, the output end of the electric telescopic rod moves, thereby driving the connecting column and the connecting block to move.

This enhances the stability of the pipe and improves the accuracy of the detection data.

[0024] 2. In this utility model, the connecting plate on the outer wall of the connecting column 2 is driven by the output end of the electric telescopic rod 2 to slide on the inner wall of the pipe body, thereby driving the nozzle on the outer wall of the liquid tank to move synchronously.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a pipeline corrosion resistance testing device, comprising a housing 1, inside which are arranged multiple fixed supports 14, each fixed support 14 having an electric telescopic rod 3, the output end of each electric telescopic rod 3 being fixedly connected to a connecting column 4, one side of each electric telescopic rod 3 being fixedly connected to a connecting block 2 13, both connecting columns 14 and connecting blocks 2 13 being rotatably connected to a connecting rod 5, one side of each connecting rod 5 being fixedly connected to a connecting rod 3 9, both connecting rod 3 9 being rotatably connected to a connecting rod 4 10, both connecting rod 4 10 being rotatably connected to a connecting ring 11, the inner wall of each connecting ring 11 being slidably connected to a fixed column 12, the inner wall of each connecting rod 5 being... Each of the connecting rods 1 and 5 is rotatably connected to a connecting block 6. Each of the connecting rods 1 and 5 is rotatably connected to a connecting rod 7. Each of the connecting rods 2 and 7 is rotatably connected to a clamping plate 8. A pipe body 15 is provided between the clamping plates 8 on both sides. A detection component is provided inside the pipe body 15. The detection component is used to detect the corrosion resistance inside the pipe body 15. The detection component includes a liquid tank 22, which is slidably connected to the inner wall of the pipe body 15. Each of the fixed supports 14 is fixedly connected to a base plate 2 at the bottom. The bottom of the base plate 2 is fixedly connected to the inner wall of the outer shell 1. The top of the fixed column 12 is fixedly connected to the inner wall of the fixed support 14. The connecting block 6 is fixedly connected to both sides of the fixed support 14. The clamping plate 8 is slidably connected inside the fixed support 14.

[0033] Specifically, during the use of the pipeline corrosion resistance testing device, the pipeline body 15 is first placed on top of the fixed support 14. Then, the electric telescopic rod 3 is activated. At this time, the output end of the electric telescopic rod 3 begins to move. Through the coordinated action of the connecting column 4 and the connecting block 13, the connecting rods 5 on both sides rotate around the connecting block 6. During this rotation, the connecting rod 5 drives the connecting rod 9 to rotate accordingly. In this way, through the transmission of the connecting rod 10, the connecting ring 11 slides on the outer wall of the fixed column 12, thereby enhancing the stability of the connecting rod 5 during rotation. At the same time, during the rotation, the connecting rod 5 also drives the clamping plate 8 to slide inside the fixed support 14 through the connecting rod 7. This continues until the clamping plate 8 is moved to the outer wall of the pipeline body 15. The clamping plate 8 exerts a squeezing effect on the outer wall of the pipeline body 15, thereby enhancing the stability of the pipeline body 15. This solves the problem that the pipeline position is prone to shift during the use of traditional equipment, thus reducing the accuracy of the test data, and lays a good foundation for subsequent testing work.

[0034] Reference Figure 3 - Figure 4 Multiple support frames 16 are fixedly connected to the outer wall of the outer shell 1. A fixing block 17 is fixedly connected to the outer wall of the outer shell 1. An electric telescopic rod 18 is fixedly connected to the top of the fixing block 17. A connecting column 19 is fixedly connected to the output end of the electric telescopic rod 18. A connecting plate 20 is fixedly connected to one end of the connecting column 19. The outer wall of the connecting plate 20 is slidably connected to the inner wall of the pipe body 15. A motor 21 is fixedly connected to one side of the connecting plate 20. The output end of the motor 21 is fixedly connected to the outer wall of the liquid tank 22. A sealing cover 23 is slidably connected inside the liquid tank 22. Multiple nozzles 24 are fixedly connected to the outer wall of the liquid tank 22.

[0035] Specifically, in the use of the pipeline corrosion resistance testing device, the electric telescopic rod 18 is first activated. The output end of the electric telescopic rod 18 drives the connecting plate 20 at one end of the connecting column 19 to move on the inner wall of the pipeline body 15. At the same time, the motor 21 drives the nozzle 24 on the outer wall of the liquid tank 22 to slide accordingly. During this process, the nozzle 24 sprays the test reagent inside the liquid tank 22 into the interior of the pipeline body 15. Next, the motor 21 is activated, and the driving force at the output end of the motor 21 drives the nozzle 24 on the outer wall of the liquid tank 22 to rotate. With the dual motion of rotation and movement on the inner wall of the pipeline body 15, the nozzle 24 can evenly and comprehensively spray the test reagent into the interior of the pipeline body 15. This spraying method allows the test reagent to fully contact the inner wall of the pipeline body 15, thereby comprehensively testing the corrosion resistance of the inner wall of the pipeline body 15. This solves the problem that traditional equipment can only test a certain area of ​​the inner wall of the pipeline body 15, improving the comprehensiveness and accuracy of the equipment's testing.

[0036] Working Principle: During the use of the pipeline corrosion resistance testing device, the pipeline body 15 is placed on top of the fixed support 14. Simultaneously, the electric telescopic rod 3 is activated. The output end of the electric telescopic rod 3 moves, driving the connecting rods 5 on both sides to rotate around the connecting block 6 via the connecting column 4 and connecting block 2 13. During this rotation, the connecting rod 5 drives the connecting rod 3 9 to rotate accordingly, which in turn drives the connecting ring 11 to slide against the outer wall of the fixed column 12 via the connecting rod 4 10. This enhances the stability of the connecting rod 5 during rotation. Simultaneously, the rotating connecting rod 5 also drives the clamping plate 8 to slide inside the fixed support 14 via the connecting rod 2 7, until the clamping plate 8 moves to the outer wall of the pipeline body 15, thus compressing the outer wall of the pipeline body 15 and reinforcing its corrosion resistance. Stability: During the use of the pipeline corrosion resistance testing device, the electric telescopic rod 18 is activated. The output end of the electric telescopic rod 18 moves the connecting plate 20 at one end of the connecting column 19, which moves against the inner wall of the pipeline body 15. The motor 21 drives the nozzle 24 on the outer wall of the liquid tank 22 to slide accordingly. The nozzle 24 sprays the test reagent inside the liquid tank 22 into the interior of the pipeline body 15. At this time, the motor 21 is activated, and the output end of the motor 21 drives the nozzle 24 on the outer wall of the liquid tank 22 to rotate. The rotation and movement of the nozzle 24 on the inner wall of the pipeline body 15 evenly sprays the test reagent into the interior of the pipeline body 15. The test reagent is used to comprehensively test the corrosion resistance of the inner wall of the pipeline body 15, improving the accuracy of the corrosion resistance test of the pipeline body 15.
