Abstract
Description
Technical Field
[0001] This utility model relates to the field of non-destructive testing auxiliary tools, and in particular to an ultrasonic water immersion pipe multi-pore 3D waterproof sealing plug. Background Technology
[0002] The premise of water immersion pipe inspection technology is that stainless steel pipes need to pass through water, which easily leads to water filling inside the pipe. On the one hand, it is difficult to dry quickly, thus affecting the implementation of subsequent processes; on the other hand, prolonged moisture is not conducive to the stability of the inner wall surface. At the same time, although the loading and unloading areas of the inspection equipment are fixed, the length and quantity of the pipes to be inspected are not fixed, resulting in low inspection efficiency and unstable inspection due to the sealing problem of stainless steel pipes. Utility Model Content
[0003] The technical problem solved by this utility model is to provide a multi-pore 3D waterproof sealing plug for ultrasonic water immersion pipes, so as to solve the problems in the background art mentioned above.
[0004] The technical problem solved by this utility model is achieved by the following technical solution:
[0005] An ultrasonic water-immersion pipe multi-pore 3D waterproof sealing plug includes a plug body and a plug handle. The plug body is composed of a first plug head, a second plug head, and a third plug head, arranged in a progressively stacked structure. The outer edge of the front end of the plug body is chamfered, and the tail end of the plug body is provided with a plug handle. The outer edges of the first and second plug heads near the plug handle are slightly larger than the inner diameter of the pipe, and the outer edge of the third plug head near the plug handle is slightly larger than the outer diameter of the pipe. This design achieves a sealing effect while preventing the plug body from being completely inserted into the pipe and difficult to remove. The plug handle facilitates the insertion and removal of the plug body.
[0006] In this invention, the plug is made of a material with a certain degree of softness, which allows the outer edge of the plug to fit more tightly against the inner wall of the tube under compression.
[0007] In this invention, the plug is trumpet-shaped.
[0008] In this invention, the plug body and the plug handle are integrally formed by 3D material printing.
[0009] In this utility model, the plug handle is provided with a boss for using the waterproof sealing plug as a waterproof sealing connection plug. The diameter of the boss is equal to the inner diameter of the pipe. This ensures that the two pipes are sealed together during uniform transmission, and because the contact surface is small, they can be easily disassembled after testing.
[0010] In this invention, the boss is a concentric ring, and the diameter of the concentric ring is slightly larger than the diameter of the plug handle, and the concentric ring has a smooth chamfer.
[0011] In this invention, the plug body, plug handle, and boss are integrally formed by 3D material printing.
[0012] In this invention, a plug is used to block the pipe to prevent water from flowing through it. However, the pipe and water are in relative motion, and velocity creates pressure. This can cause water to seep in through the gap between the plug and the pipe. Therefore, a multi-layer blocking method is used to prevent water ingress, which not only acts as a buffer but also ensures a waterproof seal. At the same time, to improve testing efficiency, the waterproof sealing plug can be equipped with a connection function. This ensures the same waterproof seal effect while facilitating the connection and disassembly of the two pipes. Therefore, one end of the waterproof sealing connector is designed with the same structure as the waterproof sealing plug, while the other end has a smooth protrusion on the plug handle for connection, reducing friction and facilitating insertion and removal.
[0013] Beneficial effects: The plug body in this utility model has a layered, stacked structure, which provides multi-layered blocking, making it difficult for water to seep into the pipe through the gaps in the pipe wall, resulting in significant waterproofing. At the same time, the plug handle is provided with a protrusion for using the waterproof sealing plug as a waterproof sealing connector. The diameter of the protrusion is equal to the inner diameter of the pipe, which ensures a sealed connection between the two pipes during uniform transmission. Because of the small contact area, it can be easily disassembled after testing. The data from the same batch of pipes tested by the probe with the same parameters will also be more accurate, improving work efficiency while ensuring the accuracy of the test results.

[0015] Figure 2 This is a schematic diagram of the 3D waterproof sealing connector structure in a preferred embodiment of the present invention. Detailed Implementation
[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0017] See Figure 1 The ultrasonic water immersion pipe multi-pore 3D waterproof sealing plug includes a first plug 1, a second plug 2, a third plug 3, and a plug handle 4. The first plug 1, the second plug 2, and the third plug 3 form a plug body with a layered stacked structure. The outer edge of the front end of the plug body is chamfered, and the plug handle 4 is provided at the tail end of the plug body. The outer edges of the first plug 1 and the second plug 2 near the plug handle 4 are slightly larger than the inner diameter of the pipe, and the outer edge of the third plug 3 near the plug handle 4 is slightly larger than the outer diameter of the pipe. This achieves the sealing function while preventing the plug body from being completely inserted into the pipe and difficult to remove. The plug handle 4 facilitates the insertion and removal of the plug body.
[0018] In this embodiment, the plug is made of a material with a certain degree of softness, which allows the outer edge of the plug to fit more tightly against the inner wall of the tube under compression.
[0019] In this embodiment, the plug is trumpet-shaped.
[0020] In this embodiment, the plug body and the plug handle 4 are integrally formed by 3D material printing.
[0021] See Figure 2 The ultrasonic water immersion pipe multi-pore 3D waterproof sealing connector includes a first plug 1, a second plug 2, a third plug 3, a plug handle 4, and a boss 5. The first plug 1, second plug 2, and third plug 3 form a plug body with a progressively stacked structure. The outer edge of the front end of the plug body is chamfered, and the plug handle 4 is located at the rear end. The outer edges of the first plug 1 and second plug 2 near the plug handle 4 are slightly larger than the inner diameter of the pipe, and the outer edge of the third plug 3 near the plug handle 4 is slightly larger than the outer diameter of the pipe. This design achieves a sealing effect while preventing the plug from being completely inserted into the pipe and difficult to remove. The plug handle 4 facilitates the insertion and removal of the plug. The boss 5, with a diameter equal to the inner diameter of the pipe, ensures a sealed connection between the two pipes during uniform transmission and allows for easy disassembly after testing due to its small contact area.
[0022] In this embodiment, the boss 5 is a concentric ring, and the diameter of the concentric ring is slightly larger than the diameter of the plug handle 4, and the concentric ring is provided with a smooth chamfer.
[0023] In this embodiment, the plug body, plug handle 4, and boss 5 are integrally formed by 3D material printing.
[0024] In this embodiment, a plug is used to block the pipe to prevent water from flowing through it. However, the pipe and water are in relative motion, and velocity creates pressure. This can cause water to seep in through the contact gap between the plug and the pipe. Therefore, a multi-layer blocking method is used to prevent water ingress, which not only acts as a buffer but also ensures a waterproof seal. At the same time, to improve testing efficiency, the waterproof sealing plug can be equipped with a connection function. This ensures the same waterproof seal effect while facilitating the connection and disassembly of the two pipes. Therefore, one end of the waterproof sealing connector is designed with the same structure as the waterproof sealing plug, while the other end has a smooth protrusion 5 on the plug handle 4 for connection, reducing friction and facilitating insertion and removal.
[0025] After being sealed with a plug, the pipe is inserted into the water tank at a constant speed, passes through the detection probe for testing, and then exits the tank. At this point, the sealing plug at the pipe's forward end acts as a barrier, blocking the backward flow of water. This triple-layered barrier provides multiple layers of protection, making it difficult for water to seep into the pipe through gaps in the pipe wall, resulting in significant waterproofing. When the pipe is about to reach the rear end for testing, another pipe with a sealing plug is connected, and testing continues until the pipe with the sealing plug exits the tank. The tested pipe is then removed, and this connection, testing, and disassembly process is repeated to complete the testing of the entire batch of pipes. This process ensures that the testing area operates stably and continuously, avoids the problem of fixed testing equipment and material handling areas that cannot be extended indefinitely, and provides more accurate data from probes with the same parameters testing the same batch of pipes. This improves work efficiency while ensuring the accuracy of test results.
[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
