Detailed Implementation

[0024] 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.

[0025] The embodiments will be described in detail below to enable those skilled in the art to better understand the present invention:

[0026] Example 1:

[0027] like Figures 1 to 6As shown, the present invention provides a penetrant testing device, comprising a first annular guide rail 1, a second annular guide rail 2, a spraying machine cart, a base 5, a drive wheel 6, a driven wheel 7, a drive motor 8, a spraying pump 9, a cleaning agent bottle 10, a penetrant bottle 11, a developer bottle 12, a cleaning agent nozzle 13, a penetrant nozzle 14, a developer nozzle 15, a first fixed support column 16, a second fixed support column 17, a first extension column 18, a first locking nut 19, a second extension column 20, a second locking nut 21, a first rubber pad 22, and a second rubber pad 23.

[0028] The first annular guide rail 1 and the second annular guide rail 2 are respectively fitted onto the outer wall of the pipe. The first annular guide rail 1 has a first guide rail groove 3, and the second annular guide rail 2 has a second guide rail groove 4. A hollow spraying area is formed between the first annular guide rail 1 and the second annular guide rail 2. The spraying machine runs around this area to complete the penetration test of the pipe.

[0029] The painting machine is mounted on a base 5, which has a drive wheel 6 and a driven wheel 7. The drive wheel 6 and driven wheel 7 are rotatably mounted on both sides of the painting machine and are arranged symmetrically to each other. There are multiple drive wheels 6 and driven wheels 7. A drive motor 8 is also mounted on the base 5. The drive motor 8 is located above the drive wheel 6 and is rotatably connected to the drive wheel 6. The drive motor 8 drives the drive wheel 6 to rotate, causing the painting machine to move in a circular motion along the first annular guide rail 1 and the second annular guide rail 2.

[0030] A spray pump 9 is mounted on a base 5. A cleaning agent bottle 10, a penetrant bottle 11, and a developer bottle 12 are mounted on one side wall of the spray pump 9. These bottles are interconnected with the spray pump 9. Below the base 5 are cleaning agent nozzles 13, penetrant nozzles 14, and developer nozzles 15, arranged in a single vertical row, corresponding one-to-one with each of the cleaning agent bottle 10, penetrant bottle 11, and developer bottle 12. Liquid spraying is achieved through the spray pump 9.

[0031] Multiple first fixed support columns 16 are provided on the inner ring sidewall of the first annular guide rail 1, and multiple second fixed support columns 17 are provided on the inner ring sidewall of the second annular guide rail 2. Each first fixed support column 16 is threadedly connected to a first extension column 18, and the first fixed support column 16 and the first extension column 18 are fixed together by a first locking nut 19. Each second fixed support column 17 is threadedly connected to a second extension column 20, and the second fixed support column 17 and the second extension column 20 are fixed together by a second locking nut 21. The ends of the first extension column 18 and the second extension column 20 are respectively provided with a first rubber pad 22 and a second rubber pad 23 for tight contact with the outer wall of the pipe, ensuring the stability of the device.

[0032] Example 2:

[0033] Based on Example 1, the operation of the spraying machine is further optimized. The spraying machine is driven by a drive motor 8, which rotates the driving wheel 6, causing the driven wheel 7 to rotate accordingly. A gear assembly for power conversion or connection is installed on the base 5, enabling the transmission of power between the driving wheel 6 and the driven wheel 7. This can be achieved by adjusting existing technologies according to actual needs, allowing the spraying machine to move at a uniform speed along the first annular guide rail 1 and the second annular guide rail 2. The spraying pump 9, according to a preset program, sequentially sprays cleaning agent, penetrant, and developer through the cleaning agent nozzle 13, penetrant nozzle 14, and developer nozzle 15, completing the penetration test of the pipeline.

[0034] First, the cleaning agent nozzle 13 sprays a cleaning agent to remove dirt and impurities from the pipe surface, ensuring that the subsequent penetrant can effectively penetrate into the cracks and defects in the pipe. Next, the penetrant nozzle 14 sprays the penetrant, which seeps into the cracks and defects in the pipe through capillary action. Finally, the developer nozzle 15 sprays the developer, which draws the penetrant out of the cracks, creating clear imaging marks that facilitate the identification of pipe defects by inspection personnel.

[0035] Example 3:

[0036] Based on Embodiment 2, the fixing method of the device is further optimized. The first annular guide rail 1 and the second annular guide rail 2 are fixed to the outer wall of the pipe by the first fixed support column 16 and the second fixed support column 17. The lengths of the first extension column 18 and the second extension column 20 can be adjusted according to the diameter of the pipe to ensure that the first rubber plate 22 and the second rubber plate 23 can fit tightly against the outer wall of the pipe, preventing the device from shaking or falling off during operation.

[0037] The first locking nut 19 and the second locking nut 21 are used to fix the length of the first extension column 18 and the second extension column 20, ensuring the stability of the device. The first rubber plate 22 and the second rubber plate 23 are made of wear-resistant and anti-slip materials, which can effectively increase the friction with the outer wall of the pipe and prevent the device from sliding.

[0038] Example 4:

[0039] Based on Example 3, the spraying precision of the spraying machine was further optimized. Through precise control of the drive motor 8, the spraying machine achieves uniform circular motion, ensuring even and comprehensive application of the cleaning agent, penetrant, and developer. The spraying pump 9 controls the spraying volume through a preset program, avoiding over- or under-spraying and ensuring the accuracy of the test results.

[0040] The cleaning agent bottle 10, penetrant bottle 11, and developer bottle 12 store the cleaning agent, penetrant, and developer, respectively. They are connected to the cleaning agent nozzle 13, penetrant nozzle 14, and developer nozzle 15 via a spray pump 9, enabling precise liquid spraying. The nozzles of the cleaning agent nozzle 13, penetrant nozzle 14, and developer nozzle 15 are designed to be adjustable, allowing for adjustment of the spray angle and range according to the pipe diameter and testing requirements, ensuring optimal spraying results.

[0041] Example 5:

[0042] Based on Example 4, the ease of operation of the device has been further optimized. The operation of the spraying machine and the spraying process can be controlled by a remote control system, eliminating the need for operators to have close contact with pipes and spraying reagents, reducing the risk of operators coming into contact with irritating reagents, and improving operational safety.

[0043] The drive motor 8 and the spray pump 9 are connected to the remote control system via wireless signal. Operators can monitor the operating status and spraying progress of the spraying machine in real time through the control panel or mobile device, and adjust the spraying parameters according to the testing requirements to ensure the smooth progress of the testing process.

[0044] In summary, this utility model provides a penetration testing device that achieves automated penetration testing of pipelines through the design of a first annular guide rail 1, a second annular guide rail 2, and a spraying mechanical cart. This device has advantages such as simple structure, convenient operation, high spraying precision, and accurate test results, effectively improving the efficiency and safety of pipeline penetration testing. It is suitable for widespread application in pipeline testing in industries such as petroleum, natural gas, water supply, and sewage.
