Description

Technical Field

[0001] This invention relates to the field of measuring instrument technology, and in particular to a phased array ultrasonic imaging probe device. Background Technology

[0002] Ultrasonic imaging detection devices are equipment that use the principle of ultrasound to visualize the internal structure of a target object. The core principle is to emit high-frequency sound waves and receive reflected / scattered signals, and then use signal processing algorithms to generate two-dimensional or three-dimensional images. They are mainly used in multiple fields such as industry, geology, and medicine.

[0003] For example, Chinese patent CN113598816B discloses an ultrasonic imaging probe and its usage method. This device, by incorporating a coupling fluid expansion and contraction compensation structure, compensates for thermal expansion or contraction of the coupling fluid inside the 3D probe, ensuring the internal cavity is always filled with coupling fluid. This prevents probe damage from affecting imaging quality, protects the safety of the 3D probe, and extends its service life.

[0004] In existing ultrasonic probe imaging devices, the coupling agent is an indispensable key material in the ultrasonic testing process. Its main function is to fill tiny gaps with the coupling agent, replacing air to form a continuous sound transmission medium to ensure the normal transmission of ultrasonic waves. However, in practical applications, when grooves appear on the surface of the workpiece to be tested, some of the coupling agent will sink into the grooves, resulting in inconsistent coupling agent thickness on the workpiece surface. Due to size limitations, the ultrasonic probe cannot completely enter the groove, resulting in a gap between the ultrasonic probe and the groove. This affects the stability of ultrasonic wave transmission and thus adversely affects the detection accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide a phased array ultrasonic imaging probe device. When the ball bearing and the movable sleeve move to the groove on the surface of the workpiece, the coupling agent inside the reservoir cavity will be discharged downward to the lower side of the movable groove through overflow groove 2 and overflow groove 1 in sequence. The added coupling agent can replenish the coupling agent inside the groove, thereby reducing the probability of gaps between the workpiece and the probe caused by the groove, so as to solve the problems mentioned in the background art.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This solution, by setting up a filling component, allows the coupling agent inside the reservoir to be discharged sequentially through overflow channel 2 and overflow channel 1 to the lower side of the movable channel when the ball and movable sleeve move to the groove on the workpiece surface. The added coupling agent can replenish the coupling agent inside the groove, thereby reducing the probability of gaps between the workpiece and the probe caused by the groove. This can reduce the impact of uneven workpiece surface on detection accuracy to a certain extent, and thus effectively improve the functionality and practicality of the ultrasonic imaging detection equipment.

[0018] 2. This solution incorporates a buffer assembly. The frame is elastically supported by a fixed base and springs on the mounting plate. The springs undergo elastic deformation to buffer the frame's vibrations. The friction between the first and second sliding sleeves further buffers and offsets the impact of the vibrations, thereby reducing the transmission of vibrations to the probe. When the ultrasonic imaging device moves along the workpiece surface, it reduces the vibrations experienced by the probe due to the unevenness of the workpiece surface, ensuring that the lower surface of the probe remains in close contact with the workpiece surface. This effectively guarantees imaging accuracy and further improves the operational stability of the ultrasonic imaging detection device.

[0019] 3. This solution incorporates a dehumidification component with two sets of moisture-absorbing plates symmetrically distributed on both sides of the probe. This effectively absorbs moisture from the air surrounding the probe, thereby reducing the impact of the surrounding air on imaging accuracy to a certain extent. The gas inside the capsule is discharged in the opposite direction to the probe through the guide cavity and vent holes. The airflow and blowing can provide a certain degree of air cooling and heat dissipation for the probe, thus reducing the impact of temperature rise on the detection and imaging effect.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 8 This invention provides a technical solution:

[0033] A phased array ultrasonic imaging probe device includes a frame 12. A storage slot 16 is embedded in the inner side of the frame 12. A sealing plate 32 is fixedly connected to the inner surface of the storage slot 16. A mounting plate 18 is slidably connected to the outer surface of the sealing plate 32. A probe 48 is fixedly connected to the lower outer surface of the mounting plate 18. A movable sleeve 11 is slidably connected to the outer surface of the frame 12. A filling assembly is provided on the lower side of the movable sleeve 11. The filling assembly includes a movable groove 20 embedded in the lower side of the movable sleeve 11. The movable groove 20 is rotatably connected to a ball bearing 21. The movable sleeve 11 is embedded with an overflow groove 22 and an overflow groove 25. The movable sleeve 11 is embedded with a liquid storage chamber 19. The upper end of the overflow groove 25 is connected to the inside of the liquid storage chamber 19. The upper surface of the ball bearing 21 is rotatably connected to a contact plate 23. The upper outer surface of the contact plate 23 is fixedly connected to a push rod 24. The upper end of the push rod 24 is fixedly connected to a sealing seat 26. The diameter of the movable groove 20 is larger than the diameter of the ball bearing 21.

[0034] The outer surfaces of the overflow groove 25 and the sealing seat 26 are both conical. An extrusion plate 27 is fixedly connected to the inner surface of the sealing seat 26. The extrusion plate 27 has a U-shaped structure. The side of the extrusion plate 27 away from the sealing seat 26 is fixedly connected to the top rod 24. There are several groups of extrusion plates 27 arranged in a ring array. The outer surface of the sealing seat 26 is in close contact with the inner wall of the overflow groove 22. The sealing seat 26 is made of elastic material.

[0035] The outer surface of the contact plate 23 is arc-shaped and made of wear-resistant material. There are several sets of balls 21. The lower side of the balls 21 extends to the outside of the movable groove 20. The upper outer surface of the movable sleeve 11 is provided with a liquid injection hole 30. The liquid injection hole 30 extends into the inside of the liquid storage cavity 19. A control valve 31 is fixedly connected to the inside of the liquid injection hole 30. The liquid storage cavity 19 is elliptical. The lower end of the overflow groove 22 is connected to the inside of the movable groove 20.

[0036] By adopting the above technical solution, the storage groove 16 on the inner side of the frame 12 is used to store and install the probe 48. The storage groove 16 is slidably supported by the mounting plate 18 through the sealing plate 32, and the probe 48 is fixedly installed through the mounting plate 18. When the ultrasonic imaging probe 48 is used to detect the workpiece, the coupling agent is first applied to the surface of the workpiece. The coupling agent can expel the air between the probe 48 and the workpiece to reduce the influence of air on the imaging accuracy. Then, an appropriate amount of liquid is injected into the reservoir 19 through the injection hole 30 and the control valve 31. A certain amount of coupling agent is applied, and then the ball bearing 21 is placed on the upper surface of the workpiece to be tested. The ball bearing 21 supports the rotation of the movable sleeve 11, while the frame 12 is pressed down, causing the frame 12 to drive the probe 48 to contact the workpiece surface for internal damage detection. When the ball bearing 21 and the movable sleeve 11 move to the groove on the workpiece surface, the ball bearing 21 will slide down a certain distance along the inside of the movable groove 20 under its own gravity. At this time, the contact plate 23 and the push rod 24 will move down synchronously under gravity. During the downward movement, the push rod 24 will drive the dense... The sealing seat 26 moves downwards synchronously, causing its outer surface to disengage from the inner wall of the overflow groove 25. At this time, the coupling agent inside the liquid storage chamber 19 will be discharged downwards through the overflow groove 25 and the overflow groove 22 to the lower side of the movable groove 20. The added coupling agent can replenish the coupling agent inside the groove, thereby reducing the probability of gaps between the workpiece and the probe 48 caused by the groove. This can reduce the impact of uneven workpiece surface on detection accuracy to a certain extent, and thus effectively improve the ultrasonic imaging detection equipment. Functionally and practically, when the ball 21 moves out of the groove, the rolling motion pushes the contact plate 23 and the push rod 24 upward. The push rod 24 drives the sealing seat 26 upward, so that the sealing seat 26 comes into contact with the inner wall of the overflow groove 25. The sealing seat 26 can seal the overflow groove 22 to prevent the coupling agent from continuing to flow. The squeezing plate 27 applies a certain elastic force to the sealing seat 26, so that the sealing seat 26 and the overflow groove 25 fit more tightly, thereby further improving the sealing effect of the overflow groove 25.

[0037] Specifically, such as Figure 2 , Figure 4 and Figure 6 As shown, a detection component is provided on the outer side of the frame 12. The detection component includes a guide groove 15 embedded in the outer surface of the frame 12. A guide block 28 is slidably connected to the inner side of the guide groove 15. A traction belt 29 is fixedly connected to the lower outer surface of the guide block 28. The lower outer surface of the traction belt 29 is fixedly connected to the lower end of the inner surface of the guide groove 15. There are two sets of guide grooves 15 and guide blocks 28, which are symmetrically distributed. The traction belt 29 is made of elastic material.

[0038] A housing 13 is fixedly connected to the upper outer surface of the frame 12. A wire 14 is electrically connected to the upper side of the outer surface of the frame 12. The wire 14 passes through the housing 13 to the upper side. The probe 48 is a phased array ultrasonic imaging probe 48.

[0039] A buffer assembly is provided on the outer side of the mounting plate 18. The buffer assembly includes a fixed seat 36 fixedly connected to the inner surface of the movable sleeve 11. A second sliding sleeve 35 is fixedly connected to the upper outer surface of the fixed seat 36. A first sliding sleeve 33 is slidably connected to the inner surface of the second sliding sleeve 35. The upper end of the first sliding sleeve 33 is fixedly connected to the lower side of the mounting plate 18. A spring 34 is fixedly connected between the fixed seat 36 and the mounting plate 18. The spring 34 is located inside the first sliding sleeve 33 and the second sliding sleeve 35. An elastic band 17 is fixedly connected to the upper surface of the upper outer surface of the mounting plate 18. The upper end of the elastic band 17 is fixedly connected to the upper side of the inner surface of the storage groove 16.

[0040] By adopting the above technical solution, when using the ultrasonic imaging inspection equipment, the operator holds the housing 13 and pushes the frame 12. When pressing the frame 12 downward, the guide groove 15, in conjunction with the guide block 28, can provide a certain guiding effect for the frame 12, thereby making the movement of the frame 12 more stable. During the movement, the frame 12 drives the mounting plate 18 to move down synchronously through the sealing plate 32. The mounting plate 18 drives the probe 48 to come into contact with the surface of the workpiece, thereby enabling continuous flaw detection of the workpiece through the probe 48. (In this application, the probe 48 is a phased array ultrasonic probe. Its core principle is that the probe 48 is composed of an array of multiple independent piezoelectric crystals (array elements). Each array element is connected to an independent excitation circuit. By precisely setting the excitation delay (focusing rule) of each array element, the ultrasonic waves emitted by array elements at different positions form a specific wavefront in space. Based on the Huygens-Fresnel principle, the ultrasonic waves emitted by each array element interfere in space. By adjusting the delay rule, the deflection of the sound beam can be controlled.) (By adjusting the angle, focusing position, and shape, flexible control of the sound beam and high-resolution imaging can be achieved.) When the working surface is uneven, the positions of the ball bearing 21 and the movable sleeve 11 will fluctuate with the workpiece surface. When the vibration of the movable sleeve 11 is transmitted to the frame 12 through the guide block 28, the frame 12 elastically supports the mounting plate 18 through the fixed seat 36 and the spring 34. The spring 34 will generate elastic deformation to buffer the vibration of the frame 12. At the same time, the sliding sleeve 1 33 and the sliding sleeve 2 35 will slide in opposite directions. The friction between the sliding sleeve 1 33 and the sliding sleeve 2 35 can buffer and offset the impact of the vibration, thereby further reducing the vibration transmitted to the probe 48. When the ultrasonic imaging device moves along the workpiece surface, it can reduce the vibration of the probe 48 due to the unevenness of the workpiece surface, so that the lower surface of the probe 48 can always keep in close contact with the workpiece surface, thereby effectively ensuring the imaging accuracy and further improving the operational stability of the ultrasonic imaging detection device.

[0041] Specifically, such as Figure 4 and Figure 7 As shown, an applicator is provided on the lower side of the movable sleeve 11. The applicator includes a squeezing block 42 fixedly connected to the inner surface of the movable sleeve 11. An installation groove 38 is embedded in the lower side of the squeezing block 42 and the movable sleeve 11. A liquid storage cotton 39 is engaged with the inner surface of the installation groove 38. A folding groove 43 is embedded between the squeezing block 42 and the movable sleeve 11. The squeezing block 42 is made of elastic material. The installation groove 38 and the liquid storage cotton 39 are both elliptical in shape.

[0042] By adopting the above technical solution, when the coupling agent is applied to the workpiece surface and when the coupling agent is added to the groove, some coupling agent will accumulate on the workpiece surface. In order to make the coupling agent application more uniform, an application component is set up. The movable sleeve 11 is fixedly installed on the extrusion block 42. The mounting groove 38 on the lower side of the movable sleeve 11 and the extrusion block 42 is used to place the liquid storage cotton 39. When the ball bearing 21 drives the movable sleeve 11 to move along the workpiece surface, the movable sleeve 11 and the extrusion block 42 will drive the liquid storage cotton 39 to move synchronously. The liquid storage cotton 39 can spread the accumulated coupling agent evenly, so that the thickness of the coupling agent on the upper side of the workpiece is kept uniform, thereby further improving the detection accuracy of the ultrasonic detection imaging device. After the work is completed, the operator can press the extrusion block 42 to squeeze the liquid storage cotton 39, thereby accelerating the discharge of the coupling agent inside the liquid storage cotton 39. The folding groove 43 between the extrusion block 42 and the movable sleeve 11 can reduce the flipping resistance of the extrusion block 42 to a certain extent.

[0043] Specifically, such as Figure 4 , Figure 7 and Figure 8 As shown, a desiccant assembly is provided on the inner side of the movable sleeve 11. The desiccant assembly includes ear seats 47 fixedly connected to the inner surface of the movable sleeve 11. A movable rod 44 is fixedly connected between two sets of ear seats 47. A moisture-absorbing plate 45 is rotatably connected to the outer surface of the movable rod 44. The moisture-absorbing plate 45 is made of organic polymer moisture-absorbing material.

[0044] A capsule 40 is fixedly connected to the outer surface of the upper end of the moisture-absorbing plate 45. The outer surface of the capsule 40 has a fan-shaped structure. The side of the outer surface of the capsule 40 away from the moisture-absorbing plate 45 is fixedly connected to the inner wall of the movable sleeve 11. An air guide groove 37 is embedded in the inner side of the movable sleeve 11. The upper end of the air guide groove 37 extends through to the upper side of the movable sleeve 11. The air guide groove 37 has an L-shaped structure.

[0045] The moisture-absorbing plate 45 has an embedded flow-guiding cavity 41, which is connected to the inside of the capsule 40. The lower outer surface of the moisture-absorbing plate 45 has an embedded air vent 46, which is connected to the inside of the flow-guiding cavity 41. There are two sets of moisture-absorbing plates 45 and movable rods 44, which are symmetrically distributed on both sides of the probe 48. The flow-guiding cavity 41 and the air vent 37 are both equipped with regulating valves. There are several sets of air vents 46, which are distributed in a linear array.

[0046] By adopting the above technical solution, the movable sleeve 11 is fixedly supported by the movable rod 44 through the ear seat 47, and the movable rod 44 is used to rotate and support the moisture-absorbing plate 45. When the air humidity is high, the two sets of moisture-absorbing plates 45 are symmetrically distributed on both sides of the probe 48, which can effectively absorb the moisture in the air around the probe 48, thereby reducing the impact of the air around the probe 48 on the imaging accuracy to a certain extent. When the movable sleeve 11 slides relative to the frame 12, the lower end of the frame 12 will contact the upper side of the moisture-absorbing plate 45 and push the moisture-absorbing plate 45 to flip downward. At this time, the movement of the moisture-absorbing plate 45 can further improve the contact effect between the moisture-absorbing plate 45 and the air. During the flipping process, the moisture-absorbing plate 45 will stretch the capsule 40, causing the capsule 40 to produce a certain degree of elastic deformation. At this time, the air around the probe 48 will enter the guide cavity 41 inside the moisture-absorbing plate 45 through the vent holes 46 on the surface of the moisture-absorbing plate 45. In this process, the dehumidification effect of the air around the probe 48 can be further improved by the full contact between the air and the moisture-absorbing plate 45. When the frame 12 is separated from the moisture-absorbing plate 45, the moisture-absorbing plate 45 is flipped back to its original position under the elastic force of the capsule 40. At this time, the moisture-absorbing plate 45, together with the movable sleeve 11, will squeeze the capsule 40. The gas inside the capsule 40 will be discharged in the opposite direction to the area around the probe 48 through the guide cavity 41 and the vent 46. The flow of gas can play a certain role in cooling the probe 48, thereby reducing the impact of temperature rise on the detection imaging effect. When the humidity in the air decreases, the gas is made to flow unidirectionally inside the guide cavity 41 by adjusting the valve. At this time, when the capsule 40 is stretched, the external air will enter the capsule 40 through the air guide groove 37. The injection of external air can further improve the air flow effect, thereby effectively improving the heat dissipation effect of the probe 48.

[0047] Working Principle: When using the phased array ultrasonic imaging probe device, the coupling agent is first applied to the workpiece surface. Then, the operator holds the housing 13 and pushes the frame 12 while simultaneously pressing down on it, causing the frame 12 to bring the probe 48 into contact with the workpiece surface for internal damage detection. The frame 12 is elastically supported by the mounting plate 18 via the fixed base 36 and spring 34. The spring 34 generates elastic deformation to buffer the vibrations of the frame 12. The friction between the sliding sleeve 1 33 and the sliding sleeve 2 35 further buffers and offsets the impact of the vibrations, thereby reducing the transmission of vibrations to the probe 48. The movable sleeve 11 and the squeezing block 42 move the liquid storage cotton 39 synchronously, which spreads the accumulated coupling agent evenly, ensuring a uniform thickness of the coupling agent on the upper side of the workpiece. When the ball bearing 21 and the movable sleeve 11 move to the groove on the surface of the workpiece, the ball bearing 21 will slide downward along the inside of the movable groove 20 under its own gravity. The coupling agent inside the liquid cavity will be discharged downward through the overflow groove 25 and the overflow groove 22 to the lower side of the movable groove 20. The added coupling agent can replenish the coupling agent inside the groove, thereby reducing the probability of gaps between the workpiece and the probe 48 caused by the groove. Two sets of moisture-absorbing plates 45 are symmetrically distributed on both sides of the probe 48, which can effectively absorb the moisture in the air around the probe 48. The moisture-absorbing plates 45, together with the movable sleeve 11, will squeeze the capsule 40. The gas inside the capsule 40 will be discharged in the opposite direction to the area around the probe 48 through the guide cavity 41 and the vent hole 46. The flow of gas can play a certain role in air cooling and heat dissipation for the probe 48.
