[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0019] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] Example: Figures 1 to 4 As shown, an ultrasonic testing water tank suitable for pipes and rods mainly consists of a water tank body 1, a drive assembly 2, and a support driven assembly 3. The ultrasonic testing instrument is mounted on the water tank body 1 to perform ultrasonic testing on the pipes and rods, which will not be described in detail here. A key technical problem addressed in this embodiment is that in existing technologies, the workpiece is typically immersed in a water tank for testing. However, the water tank cannot perform circumferential rotational testing of the workpiece during the testing process and lacks adaptability to workpieces with different outer diameters, leading to a complex testing process and affecting testing efficiency. To solve these problems, the water tank body 1 in this embodiment has an open structure. The support driven assembly 3 is installed at the output end of the drive shaft assembly 2. The support driven assembly 3 is installed inside the water tank body 1 to support the pipes and rods and rotate them under the drive of the drive assembly 2, thus achieving circumferential rotation of the pipes and rods. This avoids blind spots during the testing process and improves the testing sensitivity.

[0022] In this embodiment, the aforementioned support driven components 3 can be configured into multiple sets according to the length of the tubing. These multiple sets of support driven components 3 are equidistantly arranged along the length of the water tank body 1. When the tubing is long, its weight is distributed across multiple support points. By equidistantly arranging multiple sets of support driven components 3, the load borne by each support point can be relatively uniform, preventing deformation of the tubing or damage to the support driven components 3 due to excessive local load. Adjacent sets of support driven components 3 are connected by a coupling 4, which can be a universal coupling. During actual installation, due to manufacturing errors, installation errors, or thermal expansion during equipment operation, the two shafts may not be perfectly aligned. The universal coupling can compensate for this axial deviation to ensure the normal use of the testing water tank. The universal coupling can also compensate for radial deviation, i.e., when the center lines of the two shafts are not on the same straight line. This compensation capability can reduce vibration and stress caused by shaft misalignment, extending the service life of the equipment.

[0023] Specifically, the drive assembly 2 in this embodiment mainly consists of a drive motor 2-1, a drive drive wheel 2-2, a drive driven wheel 2-3, a timing belt 2-4, and a drive spindle 2-5. In order to effectively protect the drive motor 2-1, the drive motor 2-1 is installed on the water tank body 1, that is, to prevent the drive motor 2-1 from being immersed in water, so as to ensure the service life of the drive motor 2-1. To enable the drive motor 2-1 to drive the driven support assembly 3, in this embodiment, the drive wheel 2-2 is installed at the output end of the drive motor 2-1, the driven wheel 2-3 is installed directly below the drive wheel 2-2 and connected to it by the timing belt 2-4, and the drive shaft 2-5 is installed at the center of the driven wheel 2-3 and used to connect to the driven support assembly 3. That is, the drive motor 2-1 drives the drive wheel 2-2, which in turn drives the driven wheel 2-3 directly below it via the timing belt 2-3. The driven wheel 2-3 then drives the drive shaft 2-5, which in turn drives the driven support assembly 3 to rotate the tube / rod. To ensure the stability of the drive motor 2-1 and provide a stable driving force, a motor frame 2-6 is also installed at the bottom of the drive motor 2-1, and the motor frame 2-6 is installed on the top of the water tank body 1.

[0024] The aforementioned driven support assembly 3 in this embodiment mainly consists of a driven shaft 3-1, a driven shaft seat 3-2, and a support roller 3-3. A synchronous pulley 5 is installed at the output end of the aforementioned drive main shaft 2-5. A pair of the aforementioned synchronous pulleys 5 are spaced apart and connected by a connecting belt 7, which is also a synchronous belt. A drive auxiliary shaft 6 is installed inside the aforementioned synchronous pulley 5. The aforementioned drive auxiliary shaft 6 is adapted to the aforementioned synchronous pulley 5, and the aforementioned drive auxiliary shaft 6 is connected to the aforementioned driven shaft 3-1 through a coupling 4. The driven shaft seat 3-2 is provided with a transition hole 3-4 for the driven shaft 3-1 to pass through. The two driven shafts 3-1 pass through the two driven shaft seats 3-2 respectively. The support roller 3-3 is installed on the driven shaft 3-1. A "V"-shaped mounting position for the tube or bar is formed between the pair of support rollers 3-3. In this way, the support rollers 3-3 can rotate in the same direction and drive the tube or bar to rotate along its own circumference, so as to avoid the blind spot problem of the tube or bar during the inspection process.

[0025] To raise the height of the tubular rod and prevent it from colliding with other components in the water tank, a support shaft 3-5 is installed above the driven shaft 3-1 in this embodiment. Since there are two driven shafts 3-1, the number of support shafts 3-5 is also two, matching the number of driven shafts 3-1. The two support shafts 3-5 are spaced apart. To facilitate the installation and rotation of the support shafts 3-5, a support bearing seat 3-6 is installed above the driven shaft seat 3-2 in this embodiment. The support shaft 3-5 is installed in the support bearing seat 3-6. Gear 1 3-7 is installed on the driven shaft 3-1, and gear 2 3-8 is installed on the support shaft 3-5. Gear 1 3-7 and gear 2 3-8 mesh with each other. The support roller 3-3 is fitted around the support shaft 3-5. The surface of the aforementioned support roller 3-3 is covered with an anti-wear layer 3-3-1, or in other words, the aforementioned support roller 3-3 is a rubber-coated roller, in order to ensure the wear resistance and high mechanical strength of the support roller 3-3, and also to reduce the friction between it and the tube or bar, thereby increasing the rotation speed of the tube or bar.

[0026] In this embodiment, a support frame 8 of a certain height is also installed inside the aforementioned water tank body 1. All driven shaft seats 3-2 are mounted on the support frame 8. The support frame 8 provides stable support for the driven shaft seats 3-2, ensuring that the driven shaft seats 3-2 will not shift or deform due to external forces or their own weight during use. The support frame 8 of a certain height also separates the driven shaft seats 3-2 from the inner bottom of the water tank body 1, reducing the impact of vibrations that may occur at the bottom of the water tank body 1 on the driven shaft seats 3-2, thereby ensuring the stability of the tube / rod material during the testing process.

[0027] In this embodiment, limiting components 9 are also provided at both ends of the aforementioned driven support component 3 to prevent axial movement of the ends of the tube or rod, thus preventing the tube or rod from moving to either end or colliding with the water tank during the testing process. The aforementioned limiting component 9 mainly consists of a limiting seat 9-1, a limiting roller 9-2, and a limiting roller support 9-3. The limiting roller support 9-3 is installed on the limiting seat 9-1, and the limiting seat 9-1 is installed on the support frame 8. The limiting roller 9-2 is rotatably installed between a pair of limiting roller supports 9-3 via a connecting shaft 9-4.

[0028] This embodiment presents an ultrasonic flaw detection water tank suitable for pipes and rods. The water tank has an ingenious structure, consisting of a water tank body 1, a driving component 2, and a supporting driven component 3. During the detection process, the pipe or rod is placed directly on the supporting driven component 3. The driving component 2 drives the supporting driven component 3 to rotate, thereby achieving rotation of the pipe or rod during the detection process. This avoids blind spots in the detection process, improves flaw detection sensitivity, and enhances the user experience. This facilitates the promotion and application of the aforementioned ultrasonic flaw detection water tank suitable for pipes and rods in the field of ultrasonic flaw detection technology for pipes and rods.
