The technical solution adopted in the present invention is: an automatic spraying ultrasonic coupling agent device, including a clamp, a connecting rod, a liquid storage tank, a spray extrusion button, a guide rail, an annular support, a nozzle pipe and a return spring;

A connecting rod that can slide up and down along the guide rail is installed on the guide rail, and a ring support is fixedly connected to the lower end of the guide rail;

A clamp is fixed on the connecting rod, and a return spring is arranged between the upper end of the connecting rod and the top of the guide rail;

The liquid storage tank is fixed on the guide rail, the upper end of the liquid storage tank is provided with a spray squeeze button, and the spray squeeze button is connected with the protruding end of the upper end of the connecting rod, and the lower end of the liquid storage tank is connected with a spray pipe.

Preferably, a circular hole is provided on the wall of the annular support, and the mouth of the nozzle passes through the circular hole and faces the center of the annular support.

Preferably, the inner diameter of the annular support is larger than the diameter of the planar ultrasonic transducer probe, which is about 6.5 cm.

Preferably, the effective stroke of the return spring is equivalent to the stroke of the extrusion button, which is about 1 cm.

The invention combines the two steps of manually placing the probe and the couplant through rational design of the device, and can realize the automatic spraying of the couplant in the process of using the planar transducer to detect the building structure.

Beneficial effects: the device of the present invention realizes the quantitative spraying of couplant, which not only saves the amount of couplant, but also avoids the interference of human factors; at the same time, the device can realize one-handed operation, which reduces the manual spraying of couplant in ultrasonic testing. Greatly improved work efficiency.

Description of drawings

Fig. 1 is a schematic structural view of an automatic spraying ultrasonic coupling agent device of the present invention.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1: an automatic spraying ultrasonic couplant device, including a fixture 1, a connecting rod 2, a liquid storage tank 3, a spray extrusion button 4, a guide rail 5, an annular support 6, a nozzle 7 and a return spring 8;

A connecting rod 2 that can slide up and down along the guide rail 5 is installed, and a ring support 6 is fixedly connected to the lower end of the guide rail 5; A return spring 8 is provided; the liquid storage tank 3 is fixed on the guide rail 5, and the upper end of the liquid storage tank 3 is provided with a spray extrusion button 4, which is connected with the end protruding from the upper end of the connecting rod 2, and the liquid storage tank 3 The lower end is connected with a nozzle 7. A circular hole is provided on the wall of the annular support 6 , and the mouth of the nozzle 7 passes through the circular hole and faces the center of the annular support 6 . The inner diameter of the annular support 6 is 6.5 cm, and the effective stroke of the return spring 8 and the stroke of the extrusion button 4 are 1 cm.

During the detection process, the ultrasonic transducer is put into the fixture 1 of the device and clamped. Hold the transducer probe, align it with the measuring point, and make the ring support 6 rest on the detection surface. When the transducer probe moves to the measuring point, the connecting rod 2 will move along the guide rail 5 and press the liquid storage. Squeeze the button 4 of the tank 3, and the nozzle 7 below the liquid storage tank 3 will spray the coupling agent between the transducer probe and the measuring point. After the transducer probe touches the measuring point, there is a couplant for coupling between the two, and ultrasonic testing can be performed directly. After the detection is completed, leave the measuring point, the return spring 8 will restore the connecting rod 2, the clamp 1 and the transducer probe to the initial position, and the extrusion button 4 connected here will also reset, making it ready for the detection of the next measuring point Prepare. Go round and round to realize the automation of couplant spraying.

It should be pointed out that those skilled in the art can make some improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. All components that are not specified in this embodiment can be realized by existing technologies.
