Description
Technical Field
[0001] This invention belongs to the technical field of acoustic wave detection devices, specifically relating to an anti-interference indoor high-precision positioning ultrasonic probe array device. Background Technology
[0002] The probes used in ultrasonic testing are transducers that utilize the piezoelectric effect of materials to convert electrical energy into acoustic energy. The key component of the probe is the crystal wafer, which is a thin single-crystal or polycrystalline sheet with a piezoelectric effect. Its function is to convert electrical energy and acoustic energy into each other.
[0003] Ultrasonic probes emit high-frequency sound waves and receive the echoes reflected from obstacles, calculating distance using the time difference of sound wave propagation. They are a type of active ranging sensor. They play important roles in many fields, summarized as follows: Medical field Prenatal check-up: Real-time monitoring of fetal development via ultrasound; Abdominal organ imaging: used for morphological and structural assessment of organs such as the liver, gallbladder, and kidneys; Interventional and surgical guidance: Provides real-time image navigation in minimally invasive surgery.
[0004] Industrial Non-destructive Testing Crack and defect detection: Detecting defects such as cracks, porosity, and inclusions inside metal welds, forgings, pipes, etc. Thickness measurement: Non-contact measurement of remaining material thickness for corrosion monitoring or life assessment; Material property analysis: The uniformity or mechanical properties of materials are determined by parameters such as sound velocity and attenuation.
[0005] Cleaning and disinfection Precision instrument cleaning: Utilizing cavitation effect to remove dirt from tiny crevices in jewelry, dental instruments, optical lenses, etc.
[0006] During use, ultrasonic probes are subject to mechanical vibrations, which can cause signal transmission instability and affect the stability of the crystal piezoelectric effect, thus impacting the ranging performance. Additionally, if the probe is not in use and is exposed to external conditions for an extended period, oxidation can easily occur on the surface of the internal components, hindering the normal transmission of sound waves and causing acoustic interference, further reducing the accuracy of data detection. Summary of the Invention
[0007] The purpose of this invention is to provide an anti-interference indoor high-precision positioning ultrasonic probe array device to solve the technical problem that when the probe is subjected to mechanical vibration, the signal transmission becomes unstable, which in turn affects the stability of the crystal piezoelectric effect and the ranging effect.
[0008] To achieve the above objectives, the present invention adopts the following technical solution: An anti-interference indoor high-precision positioning ultrasonic probe array device includes: Mounting plate, the outer wall of which is fixedly connected to a rotating arm by adjusting bolts, one end of which is connected to a housing by a detachable installation method, both the upper and lower ends of which are connected to sealing covers, and a U-shaped plate is telescopically connected to the inner wall of the sealing cover; The storage and protection mechanism includes a dual-axis motor located at the center of the housing. The output shafts at both ends of the dual-axis motor are fixed on a reciprocating lead screw. A first slider that moves in the same direction is screwed on the outer wall of the reciprocating lead screw. Both ends of the first slider are fixedly connected to a panel along the width direction of the housing by bending rods. The panel is equipped with probes that are adapted to it and are evenly distributed. The first slider and the crossbeam are connected by a swing rod, and U-shaped plates are connected to both sides of the crossbeam by plug-in fixing.
[0009] Furthermore, a first slider and a crossbeam are installed on both sides of the swing rod by means of rotational connection. A positioning frame is installed on one end of the reciprocating screw away from the housing via a bearing. A first airbag that moves against the panel is installed on the top of the positioning frame. An L-shaped telescopic rod is installed on the positioning frame along the length of the housing via a support rod.
[0010] Furthermore, a U-shaped plate is connected to one movable end of the L-shaped telescopic rod, and the movable end on the opposite side is installed at the bottom of the panel. The movable end of the L-shaped telescopic rod near the U-shaped plate is connected to the crossbeam through a synchronizing rod, which is T-shaped.
[0011] Furthermore, the positioning frame and the fixed end of the L-shaped telescopic rod are connected by a fixed rod. The top of the fixed rod is provided with a multi-port pipe connected to the first airbag. The air outlet at one end of the multi-port pipe is connected to a second airbag located below the panel, and the air outlet at the other end is connected to a T-shaped tube. The inner wall of the T-shaped tube is connected to a first baffle in the height direction by a compression spring. Hydraulic oil placed inside the T-shaped tube is filled between the first baffle and the second baffle.
[0012] Furthermore, both the first baffle and the second baffle are connected to sealing grooves along the height direction of the inner wall of the T-tube. The top of the second baffle is connected to an abutment plate that extends to the outside of the T-tube and is placed below the panel via a bracket. The compression spring is symmetrically arranged with respect to the vertical central axis of the first baffle. Both ends of the T-tube have horizontal air outlets connected to telescopic columns via second sliders. The telescopic columns are perpendicular to the second sliders.
[0013] Furthermore, one end of the second slider passes through the T-shaped tube and extends to the fixed end of the telescopic column, and the second slider is connected to a groove along the length of the inner wall of the T-shaped tube. The movable end of the top of the telescopic column is fixedly connected to a movable plate, and the movable plate is connected to the inner wall of the contact plate by telescopic movement.
[0014] Furthermore, the inner wall of the contact plate is provided with an anti-detachment groove connected to the movable plate. The anti-detachment groove is concave. There is a movable cavity between the movable plate, the first airbag, and the second airbag. The top of the movable plate is provided with a contact surface connected to the panel.
[0015] Furthermore, the probe on the panel is electrically connected to a piezoelectric chip placed inside the housing. A damping block adapted to the piezoelectric chip is installed on the piezoelectric chip. A positioning hole is provided at the connection between the mounting plate and the external wall panel, and the mounting plate is locked and fixed by a bolt assembly.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: (1) In this invention, the device can be positioned and installed at a corresponding angle by means of the adjusting bolt on the rotating arm, which facilitates subsequent signal transmission. The bolt assembly on the mounting plate facilitates effective positioning and installation with the wall panel, thereby improving the stability of the connection between structural components, making operation convenient and improving work efficiency.
[0017] (2) In this invention, when the probe needs to work, the dual-axis motor starts and drives the reciprocating screws at both ends to rotate. Under the action of the screw transmission, the first slider drives the probe on the panel to move upward. At the same time, under the action of the rotation connection of the swing rod, the crossbeams at both ends drive the U-shaped plate to move outward. Since the U-shaped plate is connected to the sealing cover in a telescopic movement, the cavity can be opened during the outward movement of the U-shaped plate, so that the probe can move freely and be exposed to the outside. When the probe does not need to work, the first slider drives the probe on the panel to move downward. Under the action of the rotation connection of the swing rod, the crossbeams at both ends drive the U-shaped plate to move closer together. At this time, the cavity can be closed during the inward movement of the U-shaped plate, and the probe is stored in the cavity, thereby obtaining the corresponding sealing protection effect, which effectively improves the safety of the device. In addition, since the first sliders at both ends drive the probe to be used alternately in the same direction, rather than emitting sound waves at the same time, the phenomenon of crosstalk between multiple probe signals is avoided, which improves the stability of signal transmission.
[0018] (3) In this invention, when the upper panel of the probe is subjected to external vibration, the panel drives the first airbag to move downward, so that the gas enters the multi-port tube and the T-tube. When the gas enters the second airbag, under the expansion action, it can buffer the force on the panel by pushing upward and the reverse force. When the gas enters the T-tube, the first baffle and the second baffle drive the hydraulic oil to move upward, and can also drive the contact plate to push upward. In this way, the mechanical vibration generated by the outside can be converted into the gravitational potential energy of the hydraulic oil and the reverse kinetic energy of the contact plate, which can effectively decompose the external force. At the same time, when the gas pushes the second slider to move outward, it can drive the movable plate on the telescopic column to move synchronously. Moreover, the structural design of the telescopic column itself allows the contact plate to drive the movable end on the telescopic column to move freely up and down. During the outward movement of the movable plate, the contact surface between the movable plate and the bottom of the panel can be increased. By expanding the contact surface, the pressure can be reduced and the safety of the device can be improved. Attached Figure Description

[0022] 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.
[0023] Reference manual attached Figure 1 - Appendix Figure 8 As shown, the anti-interference indoor high-precision positioning ultrasonic probe array device includes: a mounting plate 1, a rotating arm 3 is fixedly connected to the outer wall of the mounting plate 1 by adjusting bolts 2, a housing 4 is connected to one end of the rotating arm 3 by a detachable installation method, a sealing cover 5 is connected to both the upper and lower ends of the housing 4, and a U-shaped plate 6 is telescopically connected to the inner wall of the sealing cover 5. The device can be positioned and installed at a corresponding angle by adjusting the bolt 2 on the rotating arm 3, which facilitates subsequent signal transmission. The bolt assembly on the mounting plate 1 facilitates effective positioning and installation with the wall panel, thereby improving the stability of the connection between structural components, making operation convenient and improving work efficiency.
[0024] The storage and protection mechanism 7 includes a dual-axis motor 8 located at the center inside the housing 4. The output shafts at both ends of the dual-axis motor 8 are fixed on a reciprocating screw 9. A first slider 10 that moves in the same direction is screwed on the outer wall of the reciprocating screw 9. Both ends of the first slider 10 are fixedly connected to a panel 12 along the width direction of the housing 4 by bending rods 11. Probes 13 that are adapted to and equidistantly distributed are installed on the panel 12. The first slider 10 and the crossbeam 14 are connected by swing rods 15. U-shaped plates 6 are fixedly connected to both sides of the crossbeam 14 by plugging.
[0025] Specifically, since the first sliders 10 at both ends move in the same direction, during the movement, one ranging mechanism is retracted while the other is exposed, so that they can be used alternately. The sealing cover 5 is fixedly connected to the housing 4, which provides the U-shaped plate 6 with corresponding space for movement during horizontal movement and also prevents the U-shaped plate 6 from deviating from its position during movement.
[0026] The first slider 10 and the crossbeam 14 are mounted on both sides of the swing rod 15 by means of rotational connection. The reciprocating screw 9 is mounted on the side away from the housing 4 by means of bearing 16. The top of the positioning frame 17 is mounted with a first airbag 18 that moves against the panel 12. The positioning frame 17 is mounted with an L-shaped telescopic rod 20 along the length of the housing 4 by means of support rod 19. By means of rotational connection of the swing rod 15, the vertical movement of the first slider 10 can be converted into the horizontal movement of the crossbeam 14 on the U-shaped plate 6, and can also provide corresponding guidance for the first slider 10 during the movement.
[0027] The L-shaped telescopic rod 20 has movable ends at both corners, which are connected to the fixed rod 22 of the positioning frame 17. Since one end of the L-shaped telescopic rod 20 is connected to the U-shaped plate 6, it can provide corresponding support force to the positioning frame 17, thereby ensuring the stability of the structural connection. In addition, the movable end of the L-shaped telescopic rod 20 is connected to the crossbeam 14 through the synchronous rod 21, which can ensure that the crossbeam 14 drives the U-shaped plate 6 to move freely, and also has a corresponding guiding function during the movement of the crossbeam 14.
[0028] The movable end of the L-shaped telescopic rod 20 is connected to the U-shaped plate 6 on one side, and the movable end on the opposite side is installed at the bottom of the panel 12. The movable end of the L-shaped telescopic rod 20 is connected to the crossbeam 14 via the synchronous rod 21 on the side near the U-shaped plate 6. The synchronous rod 21 is T-shaped.
[0029] The shape of the aforementioned synchronizing rod 21 can effectively fix both ends of the crossbeam 14 to the movable end of the L-shaped telescopic rod 20. The movable end at the top of the L-shaped telescopic rod 20 can also provide a certain support and connection for the panel 12, thereby improving the stability of the structural connection by providing multiple support points.
[0030] The fixed ends of the positioning frame 17 and the L-shaped telescopic rod 20 are connected by a fixed rod 22. The top of the fixed rod 22 is provided with a multi-port pipe 23 connected to the first airbag 18. The air outlet at one end of the multi-port pipe 23 is connected to the second airbag 24 located below the panel 12, and the air outlet at the other end is connected to the T-shaped pipe 25. The inner wall of the T-shaped pipe 25 is connected to the first baffle 27 in the height direction by a compression spring 26. The space between the first baffle 27 and the second baffle 28 is filled with hydraulic oil 29 placed inside the T-shaped pipe 25.
[0031] When probe 13 is needed, the dual-axis motor 8 starts and drives the reciprocating screws 9 at both ends to rotate. Under the action of screw transmission, the first slider 10 drives probe 13 on panel 12 to move upward. At the same time, under the rotational connection of swing rod 15, the crossbeams 14 at both ends drive U-shaped plate 6 to move outward. Since U-shaped plate 6 is telescopically connected inside sealing cover 5, the cavity can be opened during the outward movement of U-shaped plate 6, allowing probe 13 to move freely and be exposed to the outside. When probe is not needed, the first slider 10 drives probe 13 on panel 12 to move downward. Under the rotational connection of swing rod 15, the crossbeams 14 at both ends drive U-shaped plate 6 to move closer together. At this time, the cavity can be closed during the inward movement of U-shaped plate 6, and probe 13 is stored in the cavity, thereby obtaining the corresponding airtight protection effect, effectively improving the safety of the device. In addition, since the first slider 10 drives probe 13 to be used alternately in the same direction, rather than emitting sound waves simultaneously, the phenomenon of signal crosstalk of multiple probes 13 is avoided, improving the stability of signal transmission.
[0032] In addition, the fixing rod 22 can effectively support the connection between the multi-port tube 23 and the T-tube 25. When the first airbag 18 is subjected to force and introduces gas into the multi-port tube 23, the second airbag 24 expands and applies a reverse force to the bottom of the panel 12, thereby improving the buffering effect of the device when subjected to external forces.
[0033] During the upward movement, the hydraulic oil 29 can convert kinetic energy into gravitational potential energy. Moreover, the hydraulic oil 29 is usually incompressible. Utilizing this characteristic, the kinetic energy transfer effect and conversion rate are improved. During the upward movement of the contact plate 30, under the action of mechanical transmission, the movable plates 33 at both ends move outward simultaneously, thereby increasing the contact area between the contact plate 30 and the panel 12. This can reduce the pressure exerted by the panel 12 during the downward movement.
[0034] The first baffle 27 and the second baffle 28 are both connected to sealing grooves along the height direction of the inner wall of the T-tube 25. The top of the second baffle 28 is connected to an abutment plate 30 that extends to the outside of the T-tube 25 and is located below the panel 12 via a bracket. The compression spring 26 is symmetrically arranged with respect to the vertical central axis of the first baffle 27. The horizontal air outlets at both ends of the T-tube 25 are connected to telescopic columns 32 via second sliders 31. The telescopic columns 32 and the second sliders 31 are arranged perpendicularly.
[0035] Furthermore, the outer edges of the first baffle 27 and the second baffle 28 can be provided with sealing rings that connect to the sealing groove, which can further increase the sealing effect at the connection of the structural components and prevent liquid leakage.
[0036] When the upper panel 12 of the probe 13 is subjected to external vibration, the panel 12 drives the first airbag 18 to move downward, thereby allowing gas to enter the multi-port pipe 23 and the T-shaped pipe 25. When the gas enters the second airbag 24, under the action of expansion, it can buffer the force on the panel 12 by pushing upward and the reverse force. When the gas enters the T-shaped pipe 25, the first baffle 27 and the second baffle 28 drive the hydraulic oil 29 to move upward, and can also drive the contact plate 30 to push upward. In this way, the mechanical vibration generated by the outside can be converted into the gravitational potential energy of the hydraulic oil 29 and the reverse kinetic energy of the contact plate 30, which can effectively decompose the external force. At the same time, when the gas pushes the second slider 31 to move outward, it can drive the movable plate 33 on the telescopic column 32 to move synchronously. Moreover, the structural design of the telescopic column 32 itself allows the contact plate 30 to drive the movable end on the telescopic column 32 to move freely up and down. During the outward movement of the movable plate 33, the contact surface between the movable plate 33 and the bottom of the panel 12 can be increased. By expanding the contact surface, the pressure is reduced and the safety of the device is improved.
[0037] One end of the second slider 31 passes through the T-tube 25 and extends to the fixed end of the telescopic column 32. The second slider 31 is connected to a groove along the length of the inner wall of the T-tube 25. The movable end of the top of the telescopic column 32 is fixedly connected to a movable plate 33. The movable plate 33 is connected to the inner wall of the contact plate 30 by telescopic movement.
[0038] The inner wall of the contact plate 30 has an anti-detachment groove that connects to the movable plate 33. The anti-detachment groove is concave. Movable cavities are provided between the movable plate 33, the first airbag 18, and the second airbag 24. The top of the movable plate 33 has a contact surface that connects to the panel 12. The probe 13 on the panel 12 is electrically connected to a piezoelectric crystal placed inside the housing 4. A damping block adapted to the piezoelectric crystal is installed on it. The mounting plate 1 has a positioning hole at the connection with the external wall panel and is locked and fixed by a bolt assembly.
[0039] The damping block connected to the piezoelectric crystal is an internal component of the ultrasonic probe. Its supporting protective film and cable and other related components are conventional technical means for those skilled in the art, and will not be described in detail here. Although there are no corresponding drawings, it does not affect the effective implementation of the technical solution of the present invention.
[0040] The core function of the damping block is to optimize ultrasonic pulse characteristics and improve detection accuracy and signal-to-noise ratio. It also has specific functions such as suppressing crystal inertial vibration: ensuring the piezoelectric crystal stops vibrating as quickly as possible after oscillation begins, avoiding continuous oscillation; shortening pulse width: reducing the duration of the emitted pulse by absorbing excess energy; and absorbing back-side noise: preventing acoustic waves radiated from the back of the crystal from forming interference signals.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to specific implementations.
