Description

Technical Field

[0001] The utility model relates to the technical field of air blowing mechanisms, in particular to an air blowing mechanism used for ultrasonic testing. Background Art

[0002] Ultrasonic testing is a technology widely used in nondestructive testing and material characterization. In ultrasonic testing, the air blowing mechanism is often used to improve the accuracy and stability of the test. The air blowing mechanism can effectively remove impurities and moisture on the surface of the object to be tested by blowing air to the surface of the object to be tested, thereby creating favorable conditions for the accurate propagation of ultrasonic waves.

[0003] Existing blowing mechanisms usually use air pumps or compressors as air sources, and blow gas to the detection area through pipes and nozzles. Although this mechanism can achieve basic blowing functions, it has some problems. First, the air flow stability and uniformity of the traditional blowing mechanism are poor. The existing blowing mechanism is composed of an air pump, a pipe and a nozzle. When the traditional blowing mechanism is working, the pipe is directly connected to the air pump, which causes the air pump to be unable to adjust the air flow rate and size during operation, which can easily lead to uneven gas distribution in the detection area and affect the propagation and reception of ultrasonic waves. The traditional blowing mechanism usually needs to continuously adjust the size and direction of the air flow during the detection process to adapt to objects of different shapes and surfaces to be tested, which increases the complexity and workload of the operation. Utility Model Content

[0004] In view of the deficiencies in the prior art, the technical problem solved by the utility model is an air blowing mechanism for ultrasonic testing, which solves the problems of poor air flow stability and uniformity of the prior air blowing mechanism.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is: a blowing mechanism for ultrasonic detection, comprising a fixed seat, a slide rail is provided at the lower end of the fixed seat, the slide rail is slidably connected to the fixed seat, and an airflow generator is fixedly provided on the fixed seat; a support frame is provided at a position directly below the fixed seat, and a plurality of blowing mechanism bodies are provided on the support frame; a plurality of connecting pipes are provided on the blowing mechanism body, and the connecting pipes are connected to the airflow generator; an airflow regulator is provided at the connecting position between the connecting pipe and the blowing mechanism body; an ultrasonic transducer is fixedly provided on one side of the blowing mechanism body; a plurality of airflow derivation devices are provided at a position on the blowing mechanism body away from the ultrasonic transducer, and an ultrasonic probe is provided in the airflow derivation device, and the ultrasonic probe is electrically connected to the ultrasonic transducer; a clamping device is fixedly provided on the side of the fixed seat away from the ultrasonic transducer.

[0006] The beneficial effects of this solution are: gas is provided to the blowing body by an airflow generator, so that the provided airflow has good stability, and a gas regulator is provided between the airflow generator and the blowing mechanism, and the flow rate and flow of the airflow are adjusted by the airflow regulator, so that the airflow environment is stable and the airflow flows more evenly, and the electrical signal is converted into an ultrasonic signal by an ultrasonic converter and then transmitted to the airflow through an ultrasonic probe, thereby reducing the attenuation of ultrasonic waves propagating in the airflow and enhancing the coupling effect between ultrasonic waves and the object to be detected.

[0007] Furthermore, the blowing mechanism body is a structure that can be adjusted up and down, and the intervals of the blowing mechanism body can be adjusted according to needs, which has good flexibility.

[0008] Furthermore, the airflow export device is an airflow export device with an adjustable offset angle, which allows the user to adjust the airflow export angle according to specific application scenarios and needs. This flexibility enables the device to adapt to more different working environments and usage scenarios, improves its versatility and practicality, and by adjusting the offset angle, the airflow export effect can be optimized and energy waste can be reduced. For example, when it is necessary to direct the airflow to a specific area, by adjusting the angle of the export device, it can be ensured that the airflow acts directly on the target area, avoiding unnecessary energy loss.

[0009] Furthermore, the clamping device is a clamping device that can be extended up and down. The parts to be cleaned are clamped and fixed by the upward and downward extension, and then cleaned. The device is stable and cleans more thoroughly.

[0010] Furthermore, there are two connecting pipes, which are arranged oppositely at the two ends of the blowing device. When the connecting pipes are arranged oppositely, they can balance the airflow generated by the blowing device. This means that the airflow will not be biased to one side, but will be evenly distributed between the two connecting pipes. This balanced airflow distribution helps to ensure that the airflow in the airflow outlet device is stable and uniform, and the connecting pipes arranged oppositely can reduce the vibration and noise generated by the airflow in the pipeline. This is because the balanced airflow distribution reduces the impact of the airflow on the pipeline wall, thereby reducing the generation of vibration and noise.

[0011] Furthermore, the ultrasonic probe is arranged at the center of the airflow outlet device. Placing the ultrasonic probe at the center of the airflow outlet device can ensure that the ultrasonic energy is evenly distributed in the entire airflow area. No matter which part of the airflow outlet device, it can be effectively affected by the ultrasonic wave, thereby achieving a more uniform airflow distribution, and more effectively utilizing the ultrasonic energy, reducing unnecessary energy loss. This helps to reduce the energy consumption of the equipment and improve energy utilization efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
