Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultrasonic testing technology, and more specifically, to a water spray probe device for ultrasonic testing. Background Technology
[0002] With the widespread application of advanced composite materials in key fields such as aerospace, new energy, and transportation, the demand for non-destructive testing of their internal quality is becoming increasingly urgent. Ultrasonic testing technology, due to its high sensitivity to changes in the acoustic impedance inside the material, has become a core technical means for the quality control of composite materials.
[0003] To avoid the wear and unstable coupling problems caused by direct contact probes, water jet coupling has become a widely used detection method. Water jet coupling uses a stable jet of water as the coupling medium for sound wave transmission, keeping the ultrasonic probe in a non-contact state with the workpiece surface, thus enabling rapid, continuous, and automated detection of complex contours.
[0004] However, in traditional water jet coupling testing, the nozzle is prone to collision with irregular surfaces when following the curved surface, affecting equipment safety and scanning accuracy. At the same time, the coupling water tends to flow down the slope and accumulate, forming an unstable water film or flow, which interferes with the stable coupling and propagation of the ultrasonic beam, generating noise or signal attenuation, thereby reducing the detection resolution and reliability of internal defects such as delamination and pores. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water spray probe device for ultrasonic testing.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A water jet probe device for ultrasonic testing includes a nozzle support, a nozzle housing connected to the nozzle support, a rubber ring at the connection between the nozzle support and the nozzle housing, a nozzle head connected to the side of the nozzle housing away from the rubber ring, and a first cap at the connection between the nozzle housing and the nozzle head.
[0007] The present invention is further configured such that: an anti-collision mechanism is provided on the side of the nozzle housing near the nozzle head; a calibration head is provided at the output end of the nozzle head; and a pneumatic joint nozzle is provided at the bottom of the nozzle housing. By setting the pneumatic joint nozzle, when the probe is coupled with water spray, the pneumatic joint nozzle is activated to spray air onto the water flowing downward after being sprayed out of the nozzle head, so that it flows to both sides, reducing the influence of water flow on detection and improving detection accuracy.
[0008] The present invention is further configured such that: the anti-collision mechanism includes anti-collision level columns, a set of anti-collision level columns are connected to the side of the nozzle housing near the nozzle head, a compression spring is wound around the surface of the anti-collision level columns, and a first anti-collision bracket is connected to the end of the compression spring away from the nozzle housing.
[0009] The present invention is further configured such that: a proximity switch bracket is provided at the end of the anti-collision level column away from the nozzle housing, and a proximity switch is connected to the proximity switch bracket in the direction of nozzle head output. By setting the proximity switch, it is determined whether the detection device collides with the object being detected during operation. Once the proximity switch is triggered, the detection operation is stopped to prevent the detection device from further colliding and damaging the object being detected.
[0010] The present invention is further configured such that: a set of buffer springs is provided on the side of the first anti-collision bracket away from the nozzle housing; a second anti-collision bracket is connected to the side of the buffer springs away from the first anti-collision bracket; and an anti-collision block is provided on the side of the second anti-collision bracket away from the buffer springs. By setting the anti-collision block on the second anti-collision bracket, when the detection device collides with the object being detected, the anti-collision block comes into contact with the object being detected, thereby reducing damage to the object being detected. Furthermore, the buffer springs buffer the collision between the detection device and the object being detected.
[0011] The present invention is further configured such that: a probe seat is provided on the inner ring of the nozzle housing, a water cavity is provided between the nozzle housing and the probe seat, and a labyrinth-type waterproof mechanism is provided on the side of the water cavity away from the nozzle head. By setting the labyrinth-type waterproof mechanism, the device is sealed and waterproofed, preventing water leakage from affecting the operation and improving the service life of the device.
[0012] The present invention is further configured such that: a nozzle screen hole is provided on the side of the water cavity near the nozzle head, and a waterproof sealing ring is provided at the connection between the nozzle screen hole and the nozzle head. By providing a waterproof sealing ring at the connection between the nozzle head and the nozzle screen hole, water leakage at the connection is prevented, thereby improving the working efficiency of the nozzle.
[0013] In summary, this application includes at least one of the following beneficial technical effects of the water jet probe device for ultrasonic testing: By incorporating an anti-collision mechanism, the nozzle head is protected during the testing process, extending the device's lifespan. Anti-collision blocks on the second anti-collision bracket reduce damage to the object being tested in the event of a collision. Pneumatic joint nozzles spray air onto the water flow below during testing, reducing the impact of downward water flow on the test results and improving accuracy. A labyrinth-type waterproof mechanism within the water cavity achieves a water seal, preventing leakage and ensuring proper functioning of components, further extending the device's lifespan.

[0016] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0017] Please see Figures 1-2 The present invention provides a technical solution including a nozzle support 1, a nozzle housing 3 connected to the nozzle support 1, a rubber ring 2 at the connection between the nozzle support 1 and the nozzle housing 3, a nozzle head 4 connected to the side of the nozzle housing 3 away from the rubber ring 2, a first cap 5 at the connection between the nozzle housing 3 and the nozzle head 4, an anti-collision mechanism 6 on the side of the nozzle housing 3 near the nozzle head 4, a calibration head 7 at the output end of the nozzle head 4, and a pneumatic joint nozzle 8 at the bottom of the nozzle housing 3.
[0018] Further, see Figure 3The anti-collision mechanism 6 includes anti-collision leveling columns 61. A set of anti-collision leveling columns 61 is connected to the side of the nozzle housing 3 near the nozzle head 4. A compression spring 62 is wound around the surface of the anti-collision leveling column 61. A first anti-collision bracket 65 is connected to the end of the compression spring 62 away from the nozzle housing 3. A proximity switch bracket 63 is provided at the end of the anti-collision leveling column 61 away from the nozzle housing 3. A proximity switch 64 is connected to the proximity switch bracket 63 facing the output direction of the nozzle head 4. A set of buffer springs 66 is provided on the side of the first anti-collision bracket 65 away from the nozzle housing 3. A second anti-collision bracket 67 is connected on the side of the buffer springs 66 away from the first anti-collision bracket 65. An anti-collision block 68 is provided on the side of the second anti-collision bracket 67 away from the buffer springs 66. The anti-collision block 68 can be made of anti-collision buffer material to reduce damage to the object being detected when it collides with the anti-collision block 68.
[0019] Further, see Figure 4 The nozzle housing 3 has a probe seat 9 on its inner ring. A water cavity 10 is provided between the nozzle housing 3 and the probe seat 9. A labyrinth-type waterproof mechanism 11 is provided on the side of the water cavity 10 away from the nozzle head 4. The labyrinth-type waterproof mechanism 11 is used to seal the water flow in the water cavity 10 to prevent water leakage from the device and affect the detection work. Several rubber sealing rings can be set in the labyrinth-type waterproof mechanism 11 to improve the waterproof performance. A nozzle screen hole 12 is provided on the side of the water cavity 10 near the nozzle head 4. A waterproof sealing ring is provided at the connection between the nozzle screen hole 12 and the nozzle head 4.
[0020] In this embodiment, please refer to Figure 5 Before the ultrasonic testing begins, calibration is performed using calibration head 7. After calibration, calibration head 7 is removed to begin the testing process. The probe's drive device drives nozzle head 4 to be vertically aligned with the test point of the object being tested. Nozzle head 4 sprays a stable water column towards the test point. At the same time, pneumatic joint nozzle 8 starts working, blowing the downward-flowing coupling water to both sides. After the current test point is tested, the probe continues to perform automated testing according to the drive device until the test is completed. When the object being detected collides with the probe, the object first contacts the anti-collision block 68, and the buffer spring 66 further absorbs the energy to reduce the damage caused by the collision. This continues until the second anti-collision bracket 67 presses the proximity switch 64. Once the proximity switch 64 is triggered, the collision emergency operation is activated, the power is cut off, the detection work is stopped, and a collision alarm is issued. After receiving the collision alarm, the staff checks the collision damage and then further determines whether to continue the detection work.
