Technical Field

[0001] The utility model relates to the technical field of ultrasonic testing, in particular to a shear wave transducer with a high-temperature resistant structure. Background Technique

[0002] Ultrasonic testing technology is a technology that uses the principles of ultrasonic wave propagation, reflection, and scattering in objects for detection and measurement. It is widely used in medical ultrasonic imaging, industrial non-destructive testing, material analysis, fluid measurement, underwater detection and other fields, and is suitable for application scenarios that require deep detection and precise measurement;

[0003] As a type of ultrasonic sensor, a shear wave transducer is mainly used to generate and receive shear waves, which can propagate in materials at an inherent angle. According to the strength and time delay of the reflected signal, various information such as the internal structure, surface defects, thickness, and density of the object can be analyzed;

[0004] The existing shear wave transducers cannot quickly disassemble the cable, resulting in more time and effort required for disassembly when the shear wave transducer needs to be repaired or replaced, thus affecting the usability and production efficiency of the equipment. Therefore, a shear wave transducer with a high-temperature resistant structure is proposed to solve the above problems. Summary of the Utility Model

[0005] To make up for the above deficiencies, the utility model provides a shear wave transducer with a high-temperature resistant structure, aiming to improve the problem that it is difficult to repair or replace the shear wave transducer due to the inability to quickly disassemble the cable in the existing technology.

[0006] To achieve the above objective, the utility model adopts the following technical scheme:

[0007] A shear wave transducer with a high-temperature resistant structure includes a shear wave transducer housing. A protection component is arranged inside the shear wave transducer housing, and the protection component is used to make the shear wave transducer housing more resistant to high temperature and have good electrical insulation performance. Two connection ports are fixedly connected to the outer periphery of the shear wave transducer housing. A cable is slidably connected inside the connection ports. Two mounting shells are fixedly connected to the outer periphery of the shear wave transducer housing. A sliding rod is slidably connected to the top of the mounting shell. A connecting block is fixedly connected to the bottom of the sliding rod. Two rotating rods are rotatably connected inside the connecting block. A slider is slidably connected to the outer periphery of the rotating rod away from the connecting block. The outer periphery of the slider is slidably connected inside the connection port and the cable. An installation block is fixedly connected to the top of the sliding rod. A spring is fixedly connected to the bottom of the installation block;

[0008] As a further description of the above technical solution:

[0009] The protection component includes a protective layer, which is coated inside the shear wave transducer housing, and an insulating layer is coated inside the protective layer;

[0010] As a further description of the above technical solution:

[0011] One end of the spring away from the mounting block is fixedly connected to the top of the mounting shell, and the spring is sleeved on the outer periphery of the sliding rod;

[0012] As a further description of the above technical solution:

[0013] A protective cover is rotatably connected to the right side of the mounting shell;

[0014] As a further description of the above technical solution:

[0015] The material of the protective layer is ceramic, and the material of the insulating layer is epoxy resin;

[0016] As a further description of the above technical solution:

[0017] A sealing gasket is fixedly connected to one side of the protective cover, and the material of the sealing gasket is silicone rubber;

[0018] As a further description of the above technical solution:

[0019] A chute is provided inside the slider, and one end of the rotating rod is slidably connected in the chute provided inside the slider;

[0020] As a further description of the above technical solution:

[0021] The outer periphery of the cable is slidably connected inside the mounting shell.

[0022] The utility model has the following beneficial effects:

[0023] 1. In the utility model, by pressing the mounting block, the sliding rod slides inside the mounting shell, and at the same time, the spring is compressed. The sliding of the sliding rod drives the connecting block to move, and the movement of the connecting block drives the two rotating rods to rotate. When the two rotating rods rotate, they drive the two sliders to slide out of the cable, releasing the fixation of the cable, so that the cable can be quickly disassembled for repairing or replacing the shear wave transducer housing.

[0024] 2. In the utility model, by coating a protective layer inside the shear wave transducer housing, the shear wave transducer housing can have good high-temperature tolerance and hardness, and at the same time, it does not affect the transmission of ultrasonic waves. By coating an insulating layer inside the protective layer, the shear wave transducer housing can maintain good electrical insulation performance in a high-temperature environment, avoiding electrical faults or leakage.

Two mounting shells 2 are fixedly connected to the outer periphery of the shear wave transducer housing 1, the mounting shells 2 are used to protect the connection ports 13, a sliding rod 8 is slidably connected to the top of the mounting shell 2, a connecting block 7 is fixedly connected to the bottom of the sliding rod 8, and the connecting block 7 can be driven to move when the sliding rod 8 slides. Two rotating rods 9 are rotatably connected inside the connecting block 7, and the two rotating rods 9 will be driven to rotate when the connecting block 7 moves. A slider 11 is slidably connected to the outer periphery of the end of the rotating rod 9 away from the connecting block 7. When the rotating rod 9 rotates, the slider 11 is driven to slide out of the cable 4. The outer periphery of the slider 11 is slidably connected inside the connection port 13 and the cable 4. When the slider 11 slides out of the cable 4, the fixing of the cable 4 is released, so that the cable 4 can be disassembled, thereby repairing or replacing the shear wave transducer housing 1. A mounting block 5 is fixedly connected to the top of the sliding rod 8, a spring 6 is fixedly connected to the bottom of the mounting block 5. Pressing the mounting block 5 can drive the sliding rod 8 to slide and compress the spring 6 at the same time. Releasing the mounting block 5 makes the spring 6 recover and drives the mounting block 5 to reset.

[0033] Referring to Figures 1 - 4 , a protection component is arranged inside the shear wave transducer housing 1, and the protection component is used to make the shear wave transducer housing 1 more resistant to high temperature and have good electrical insulation performance. The protection component includes a protective layer 14, the protective layer 14 is coated inside the shear wave transducer housing 1, the protective layer 14 is used to make the shear wave transducer housing 1 have good high-temperature tolerance and hardness, and an insulating layer 12 is coated inside the protective layer 14. The insulating layer 12 is used to make the shear wave transducer housing 1 maintain good electrical insulation performance in a high-temperature environment.

[0034] Referring to Figure 2 , Figure 3 and Figure 4, one end of the spring 6 away from the mounting block 5 is fixedly connected to the top of the mounting shell 2. The spring 6 is sleeved on the outer periphery of the sliding rod 8, which can prevent the spring 6 from shifting and shaking, making the spring 6 more stable when compressed and restored. A protective cover 3 is rotatably connected to the right side of the mounting shell 2. The protective cover 3 can rotate to protect the interior of the mounting shell 2. The material of the protective layer 14 is ceramic, and the ceramic material has high-temperature stability and hardness.

One side of the protective cover 3 is fixedly connected with a sealing gasket 10, and the material of the sealing gasket 10 is silicone rubber.

The sliding of the sliding rod 8 drives the connecting block 7 to move, and the movement of the connecting block 7 drives the two rotating rods 9 to rotate. When the two rotating rods 9 rotate, they will drive the two sliders 11 to slide out of the cable 4, so that the cable 4 can slide out of the connecting port 13 to achieve quick disassembly, so as to repair or replace the shear wave transducer housing 1. After the shear wave transducer housing 1 is repaired or replaced, then slide the cable 4 into the connecting port 13, and then release the mounting block 5 to restore the spring 6, driving the two sliders 11 to slide into the cable 4 for fixation. The protective layer 14 coated inside the shear wave transducer housing 1 can make the shear wave transducer housing 1 have good high-temperature tolerance and hardness, and at the same time does not affect the transmission of ultrasonic waves. By coating the insulating layer 12 inside the protective layer 14, the shear wave transducer housing 1 can maintain good electrical insulation performance in a high-temperature environment, avoiding electrical failures or leakage. When the shear wave transducer housing 1 is not in use, first rotate the protective cover 3, and the sealing gasket 10 will protect the connecting port 13 to prevent dust, moisture or other pollutants from entering the inside of the connecting port 13.
