Description

Technical Field

[0001] The utility model belongs to the technical field of ultrasonic flaw detection devices, in particular to a portable ultrasonic flaw detection device with self-spraying coupling agent. Background Art

[0002] Ultrasonic flaw detection devices are important tools for detecting internal defects or structural features in materials. Traditionally, these devices rely on coupling agents to ensure that ultrasonic waves can effectively propagate to the surface and interior of the object being inspected. However, current ultrasonic flaw detection devices have several technical limitations and shortcomings:

[0003] 1. Although coupling agent is essential for flaw detection, current technology does not yet allow the detection device to be combined with the coupling agent and then sprayed directly. This means that operators must apply or spray the coupling agent manually. This method is not only time-consuming and labor-intensive, but also affects the efficiency and accuracy of the operation.

[0004] 2. Most existing ultrasonic flaw detection devices are designed so that the coupling agent and the flaw detection device are used and taken separately, which makes them difficult to carry when in use. This limits their practical application in the field or in environments that require mobile operation. Utility Model Content

[0005] The purpose of the utility model is to provide a portable ultrasonic flaw detection device with self-spraying coupling agent to solve the problems existing in the prior art.

[0006] The lifting mechanism that lifts up and down is that lifting device is installed in the lifting mode of lifting, and the lifting mechanism of lifting is installed in the lifting mode of lifting.

[0007] Preferably, a connecting column is provided on one side of the lower slider, and a drag ring is provided on the connecting column, and the drag ring encloses the flaw detection telescopic tube.

[0008] Preferably, an L-shaped handle is provided on one side of the upper partition.

[0009] Preferably, the width of the embedding groove is equal to the diameter width of the discharge telescopic tube.

[0010] Preferably, the shoulder strap is an elastic band.

[0011] Preferably, the discharge holes are opened at equal intervals.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] The utility model adopts a U-shaped shell design and is equipped with a shoulder strap, so that the entire device can be easily carried and moved, and can carry accessories and facilitate operation. It is suitable for on-site and environments that require mobile operation. The flaw detector is installed on a vertical electric slide rail. The flaw detector can move horizontally along the slide rail to adjust the position and angle of the probe to adapt to different detection needs and workpiece shapes. The flaw detection telescopic tube is connected to one side of the flaw detector, and the probe is located at the far end of the telescopic tube. This design facilitates accurate ultrasonic flaw detection in narrow gaps or hard-to-reach areas. The material storage box is installed above the lower partition. The coupling agent is sprayed onto the surface of the object to be inspected through the discharging telescopic tube. One end of the discharging telescopic tube extends into the embedded groove. The pressure plate prevents the discharging telescopic tube from shaking. The brush on the connecting column ensures that the coupling agent is evenly covered on the surface of the object to be inspected, reducing the manual intervention of the operator. The equipment is equipped with automatic control components such as electric slide rails and electric cylinders, which help to improve the positioning accuracy of the flaw detector and the consistency of operation, thereby improving the accuracy and efficiency of flaw detection.

[0014] In summary, this couplant self-spraying portable ultrasonic flaw detection device effectively solves the problems of couplant dependence and inconvenient operation in traditional ultrasonic flaw detection devices through its innovative structural design, improves the operating efficiency and detection accuracy of the equipment, and is suitable for practical application needs in various industrial scenarios.
