[0032] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Please refer to Figures 1 to 3This embodiment discloses an ultrasonic transducer clamping device, including a first clamp 100, a second clamp 200, and a telescopic assembly 300. The first clamp 100 includes a first upper clamp 110 and a first lower clamp 120, which are movably connected to the first upper clamp 110. One end of the first upper clamp 110 and the first lower clamp are respectively provided with a plurality of first placement slots 121 for placing an ultrasonic transducer 400. The second clamp 200 includes a second upper clamp 210 and a second lower clamp 220, which are movably connected to the second lower clamp 220. One end of the second upper clamp 210 and the second lower clamp 220 are respectively provided with a plurality of second placement slots 221 for placing an ultrasonic transducer 400. The two ends of the telescopic assembly 300 are respectively connected to the first clamp 100 and the second clamp 200. Multiple ultrasonic transducers 400 are fixed by the first clamp 100 and the second clamp 200 respectively, and the distance between the first clamp 100 and the second clamp 200 is adjusted by the telescopic component 300, thereby achieving efficient clamping and positioning of the ultrasonic transducers 400. The first upper clamp 110 and the first lower clamp 120 are movably connected, and each has multiple first placement slots 121 at one end for placing and fixing multiple ultrasonic transducers 400. The second upper clamp 210 and the second lower clamp 220 are also movably connected, and each has multiple second placement slots 221 at one end for placing and fixing multiple ultrasonic transducers 400. The first clamp 100 and the second clamp 200 are connected by a telescopic component 300. By adjusting the length of the telescopic component 300, the distance between the first clamp 100 and the second clamp 200 can be precisely adjusted to ensure that the ultrasonic transducers 400 are firmly and accurately clamped and positioned. This achieves efficient and stable clamping and operation of the ultrasonic transducers 400, which can improve the installation accuracy, stability and ease of operation of the ultrasonic transducers 400, thereby improving the efficiency and reliability of pipeline inspection.

[0034] Please refer to Figure 1 and Figure 2 The first upper clamp 110 and the first lower clamp 120 both have semi-circular cross-sections and share the same axis and radius, allowing them to be combined into a cylindrical structure. Multiple first placement slots 121 are evenly distributed circumferentially on one side of the first clamp 100. The semi-circular cross-sections of the first upper clamp 110 and the first lower clamp 120, along with their shared axis and radius, allow them to cooperate and form a cylindrical structure, facilitating the mounting of the device onto the pipe 500 and creating a stable clamping structure. By evenly distributing the multiple first placement slots 121 on one side of the first clamp 100, the multiple ultrasonic transducers 400 can be arranged, positioned, and fixed in an orderly manner, thereby improving detection efficiency.

[0035] Please refer to Figure 3The first upper clamp 110, the first lower clamp 120, the second upper clamp 210, and the second lower clamp 220 are all equipped with magnets 122. The first upper clamp 110 and the first lower clamp 120 are attracted together by magnets 122; the second upper clamp 210 and the second lower clamp 220 are also attracted together by magnets 122. By providing magnets 122, the upper and lower clamps can be quickly positioned and fixed by magnetic attraction, facilitating disassembly and installation, thereby improving the efficiency and accuracy of assembly operations. When the operator aligns the first lower clamp 120 and the second lower clamp 220 with the position to be assembled, as the upper and lower clamps approach each other, the magnetic force causes the upper and lower clamps to automatically align due to the attraction of the polarities of the magnets 122. The action of the magnets 122 enables the upper and lower clamps to quickly attract each other, thereby achieving positional alignment and reducing the time required for manual adjustment and fixing.

[0036] Please refer to Figure 5 The second clamp 200 has the same structure as the first clamp 100 and is symmetrically installed on the pipe 500. The second clamp 200 has the same structure as the first clamp 100 and is installed on the pipe 500 in a symmetrical manner to effectively position and fix multiple ultrasonic transducers 400.

[0037] Please refer to Figure 3 Both the first placement slot 121 and the second placement slot 221 are U-shaped grooves. Multiple ultrasonic transducers 400 are placed into the first placement slot 121 and the second placement slot 221 respectively. Because both are U-shaped grooves, they provide stable lateral support, preventing the ultrasonic transducers 400 from sliding or shaking in the horizontal direction. The ultrasonic transducers 400 are positioned within the inner cavity of the U-shaped structure, ensuring that the ultrasonic transducers 400 remain stable during use. The U-shaped groove design improves the ease of placement and coupling effect of the ultrasonic transducers 400.

[0038] Please refer to Figure 3 A gripper is installed in either the first placement slot 121 or the second placement slot 221. When the gripper is installed in the first placement slot 121 or the second placement slot 221, it adapts to various models of ultrasonic transducers 400. The gripper enhances its gripping force, ensuring a reliable connection between the gripper and the ultrasonic transducer 400, thereby achieving precise and stable positioning and fixing operations. It can effectively hold ultrasonic transducers 400 of different specifications and sizes. In addition, both the first clamp 100 and the second clamp 200 are made of rubber material, which facilitates installation and disassembly.

[0039] Please refer to Figure 3The telescopic assembly 300 includes a telescopic cylinder 310 and a telescopic rod 320, with the telescopic rod 320 slidably inserted into the inner cavity of the telescopic cylinder 310. The telescopic assembly 300 adjusts the distance between the first clamp 100 and the second clamp 200 through the sliding insertion of the telescopic cylinder 310 and the telescopic rod 320. Multiple ultrasonic transducers 400 in the first placement slot 121 form a first ultrasonic transducer array, and multiple ultrasonic transducers 400 in the second placement slot 221 form a second ultrasonic transducer array. When a greater distance is needed, the telescopic rod 320 slides out along the inner cavity of the telescopic cylinder 310, increasing the distance between the first and second ultrasonic transducer arrays to obtain more detection information. When a shorter distance is needed, the telescopic rod 320 retracts into the telescopic cylinder 310 by sliding in the opposite direction, bringing the distance between the first and second ultrasonic transducer arrays closer together to obtain higher detection accuracy. The flexible distance adjustment via the telescopic assembly 300 adapts to different usage needs, offering convenience and practicality.

[0040] Please refer to Figure 3 Both the first upper clamp 110 and the first lower clamp 120 are equipped with laser rangefinders 123. First, the telescopic assembly is adjusted so that the first upper clamp 110 and the second upper clamp 210 are approximately at a predetermined position. Then, the laser rangefinders 123 are used to measure the distance between the first upper clamp 110 and the second upper clamp 210. Next, the telescopic assembly 300 is fine-tuned to ensure that the measurement data from all laser rangefinders 123 are consistent, thereby guaranteeing that the distance between the ultrasonic transducer 400 in the first placement slot 121 and the ultrasonic transducer 400 in the second placement slot 221 is the preset value, improving detection accuracy.

[0041] Please refer to Figure 4 The ultrasonic transducer clamping device also includes a handheld terminal 600, which is wirelessly connected to the laser rangefinder sensor 123. Through this wireless connection, the ultrasonic transducer clamping device can control the laser rangefinder sensor 123 to perform measurements. The laser rangefinder sensor 123 measures the distance between the first upper clamp 110 and the second upper clamp 210 by emitting a laser beam and wirelessly transmits the measurement data to the handheld terminal 600, ensuring the efficiency and accuracy of the detection process.

[0042] Please refer to Figure 5 This embodiment also discloses a pipeline inspection system, including the ultrasonic transducer clamping device described above.

[0043] During testing, please refer to Figure 5First, place the first upper clamp 110 and the second upper clamp 210 on the pipe 500. First, adjust the telescopic rod 320 so that the first upper clamp 110 and the second upper clamp 210 are approximately at the predetermined positions. Then, use a laser rangefinder 123 to measure the distance between the first upper clamp 110 and the second upper clamp 210. Next, fine-tune the telescopic rod 320 to ensure that the measurement data from all laser rangefinders 123 are consistent, thereby ensuring that the distance between the ultrasonic transducers 400 in the first placement slot 121 and the ultrasonic transducers 400 in the second placement slot 221 are both preset values, thus improving detection accuracy. After setting the spacing, install the first lower clamp 120 and the second lower clamp 220, causing the two clamps to attract each other, thus fixing the first clamp 100 and the second clamp 200 to the surface of the pipe 500. After the first clamp 100 and the second clamp 200 are fully installed on the pipe surface, a coupling agent is applied to the bottom surface of the ultrasonic transducer 400. Multiple ultrasonic transducers 400 are then placed in the first placement groove 121 and the second placement groove 221, respectively, and ultrasonic non-destructive testing is performed. In actual testing, to avoid the first clamp 100 and the second clamp 200 affecting the ultrasonic measurement waveform, the first clamp 100 and the second clamp 200 can be disassembled after the ultrasonic transducer 400 is installed on the pipe surface 500.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
