DETAILED DESCRIPTION

[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0019] The following describes an embodiment of the present invention based on its overall structure.

[0020] It should be noted that the evaluation platform 1 is connected to an external power supply via a power supply line to ensure stable operation of each module.

[0021] In this embodiment, please refer to Figure 1-Figure 7As shown, a composite material structure interface damage assessment device includes an assessment platform 1, a sealing cover 2, an ultrasonic probe 302, and a processing mechanism 4 and an analysis and evaluation module 109 inside the assessment platform 1. A touch screen panel 102 is installed on the side of the assessment platform 1 close to the human body. The touch screen panel 102 is connected to the analysis and evaluation module 109 via a data cable. A placement groove 101 is provided on the upper surface of the assessment platform 1. The placement groove 101 is used to place a composite material structure sample. The sealing cover 2 is rotatably mounted on the assessment platform 1 and is used to cover the placement groove 101. The ultrasonic probe 302 is connected to the analysis and evaluation module 109 via a wire 3. A water bag 303 is installed at the end of the ultrasonic probe 302 through a clamp for coupling to the sample surface. A cleaning chamber 105 is provided inside the assessment platform 1. A connected insertion groove 106 is provided on the upper surface of the assessment platform 1 at the cleaning chamber 105. The insertion groove 106 is used to guide the ultrasonic probe 302 into the cleaning chamber 105. A top block 301 is fixed to the top of the ultrasonic probe 302, and both side walls of the top block 301 are provided with a card slot 3011. Side blocks 8 are fixed on both sides of the upper surface of the evaluation platform 1 on the insertion slot 106. The outer walls of the two side blocks 8 are provided with a storage slot 801. Plug-in blocks 802 are movably provided in the two storage slots 801. The end faces of the two plug-in blocks 802 are provided with upward inclined surfaces that match the card slot 3011. A pull rod 803 is fixed at the center of the other end of the two plug-in blocks 802. The two pull rods 803 pass through the side block 8 and extend to the outside, and the two pull rods 803 are sleeved with a support spring 804. The two ends of the two support springs 804 are respectively fixedly connected to the end face of the plug-in block 802 and the wall of the storage slot 801. Oblique grooves 3012 are provided on both sides of the top block 301 below the card slot 3011, and the two oblique grooves 3012 match the inclined surfaces provided on the plug-in block 802. The processing mechanism 4 includes a cleaning component 5, a driving component 6 and an opening and closing component 7. The cleaning component 5 is arranged at the bottom of the cleaning chamber 105. The interior of the evaluation platform 1 is provided with a driving chamber 107 on one side of the cleaning chamber 105. The cleaning component 5 is used to clean the surface of the water bag 303. The driving component 6 is arranged in the driving chamber 107. The opening and closing component 7 is located on one side of the sealing cover 2 and is used to control the flipping. The driving component 6 is connected to the cleaning component 5 and the driving component 6 respectively.

[0022] When conducting damage assessment on composite material structure samples, the staff starts the driving component 6 through the touch screen panel 102. The driving component 6 drives the cleaning component 5 to wipe the surface of the water bag 303, and drives the opening and closing component 7 to operate, so that the sealing cover 2 slowly opens to expose the placement slot 101. Then, the composite material structure sample is placed in the placement slot 101, and then the pull rod 803 is manually pulled to both sides. The pull rod 803 drives the plug-in block 802 to move and squeeze the support spring 804, canceling the fixation of the plug-in block 802 on the top block 301. Then the staff pinches the top block 301, pulls out the ultrasonic probe 302 and inserts it into the through slot 106, and inserts the ultrasonic probe The water bag 303 at the end of 302 is in close contact with the sample surface to ensure the coupling effect. Then, ultrasonic testing is started. The ultrasonic probe 302 moves at a constant speed along a certain path on the surface of the composite material structure sample, emitting high-frequency ultrasonic waves. The ultrasonic waves propagate inside the composite material and generate reflected waves when encountering interface damage. The reflected waves are received by the probe and converted into electrical signals. The analysis and evaluation module 109 processes these signals, analyzes the phase, amplitude, propagation time and other characteristics of the reflected waves, and determines the location, size and extent of the damage based on these characteristics. Based on the analyzed structure, the severity of the composite material structure interface damage is evaluated, and the evaluation report is displayed on the touch screen panel 102. After the assessment is completed, the staff only needs to reinsert the ultrasonic probe 302 into the through slot 106. When the inclined slot 3012 of the top block 301 contacts the inclined surface of the plug-in block 802, the downward movement of the top block 301 will push the plug-in block 802 to move into the storage slot 801 until the slot 3011 is located at the plug-in block 802. Under the elasticity of the supporting spring 804, the plug-in block 802 will be inserted into the slot 3011 to complete the fixation of the ultrasonic probe 302. At this time, the surface of the water bag 303 will be located at the cleaning component 5. Then the driving component 6 is started again, driving the cleaning component 5 to clean and wipe the water bag 303, and at the same time driving the opening and closing component 7 to slowly close the sealing cover 2 to seal and protect the placement slot 101. Therefore, the application of the automated cleaning system greatly reduces the time and labor required for manual wiping. After the inspection work is completed, the device can quickly clean the water bag 303 without waiting for manual cleaning, thereby improving the efficiency of the overall inspection process, avoiding the inefficiency and unevenness of manual wiping, and improving the standardization and standardization of the inspection work, which is conducive to improving the overall inspection level and quality control.

Both ends of the transmission shaft 605 are rotatably connected to the cavity wall of the drive chamber 107. The outer wall of the transmission shaft 605 is located next to the worm gear 604 and is fixedly sleeved with a first bevel gear 606. The tooth surface of the first bevel gear 606 is meshed with a second bevel gear 607. A shaft rod 608 is fixedly provided at the center of the second bevel gear 607. One end of the shaft rod 608 is rotatably connected to the cavity wall of the drive chamber 107. The cleaning assembly 5 includes three annular flushing plates 501, which are fixedly connected by four connecting rods 502. Several nozzles are provided on the inner walls of the three flushing plates 501. The inner diameters of the three flushing plates 501 are all larger than the outer diameter of the ultrasonic probe 302. A vertical rod 504 is rotatably mounted at the center of the bottom of the cleaning chamber 105. A curved plate 503 is fixed to the top of the vertical rod 504. A soft brush 5031 is mounted on the curved plate 503. Four horizontal rods 505 are evenly fixed to the outer wall of the vertical rod 504, and driven gears 506 are fixed to the ends of the four horizontal rods 505. The interior of the evaluation platform 1 is located on the other side of the cleaning chamber 105 and is provided with a solvent chamber 103 and a clean water chamber 104 in sequence. Water pumps 508 are installed at the bottom of the solvent chamber 103 and the clean water chamber 104. The output ends of the two water pumps 508 pass through the chamber and are connected to vertical liquid supply pipes 507. The liquid supply pipes 507 are connected to the three flushing plates 501 through three branches. A drainage port 108 communicating with the cleaning chamber 105 is provided on the side of the evaluation platform 1 away from the human body. The upper surface of the evaluation platform 1 is bonded with fixed blocks 201 on both sides of the sealing cover 2. The bottoms on both sides of the sealing cover 2 are rotatably connected to the fixed blocks 201 through rotating rods. The opening and closing component 7 includes a connecting shaft 705. One end of the connecting shaft 705 passes through the fixed block 201 and is fixedly connected to the rotating rod. The other end of the connecting shaft 705 is connected to the horizontal shaft 702 through a magnetic coupler 701. The bottom end of the magnetic coupler 701 is fixed to the upper surface of the evaluation platform 1 with screws. The horizontal shaft 702 and the outer wall of the shaft 608 set in the driving component 6 are both provided with grooves 703. Transmission wheels are fixedly sleeved in the two grooves 703 and are connected through a transmission chain 704.

[0024] When the surface of the water bag 303 needs to be cleaned, the staff inserts the ultrasonic probe 302 into the through slot 106. At this time, the water bag 303 will be located in the center of the three flushing plates 501, and the soft brush 5031 on the curved plate 503 will also contact the surface of the water bag 303. The water pump 508 in the solvent chamber 103 is first started through the touch screen panel 102. The solvent is sprayed onto the surface of the water bag 303 through the liquid supply pipe 507 and the branch pipe. At the same time, the dual-axis motor 601 of the driving component 6 works. The output end drives the driving gear 602 to rotate, and the driving gear 602 drives the meshing driven gear 506 to rotate, which in turn drives the vertical rod 504 to rotate through the attached horizontal rod 505. The vertical rod 504 drives the curved plate 503 and the soft brush 5031 to rotate synchronously. The soft brush 5031 scrubs the surface of the water bag 303 in all directions. The solvent and scrubbing work together to effectively remove stains. Then, the water pump 508 in the clean water chamber 104 is started to flush away the residual solvent with clean water to ensure thorough cleaning. The other output end of the dual-axis motor 601 drives the worm 603 to rotate, and the worm 603 drives the worm wheel 604 to rotate, which drives the first bevel gear 606 to rotate through the transmission shaft 605, thereby causing the second bevel gear 607 to rotate synchronously, and the shaft 608 rotates accordingly. The transmission wheel on the shaft 608 drives the horizontal shaft 702 to rotate through the transmission chain 704. The rotation of the horizontal shaft 702 drives the magnetic coupler 701 to work, causing the connecting shaft 705 to rotate accordingly, and then drives the sealing cover 2 to rotate through the driving rod, so that the sealing cover 2 can be rotated from vertical to horizontal, effectively covering the placement slot 101. At the same time, after the sealing cover 2 rotates to the horizontal position, the magnetic coupler 701 will not hinder the continuous rotation of the horizontal shaft 702, ensuring continuous cleaning of the surface of the water bag 303. The dirt washed down is discharged with water through the drain port 108, keeping the internal environment of the equipment clean. The entire cleaning process is highly efficient and coordinated, avoiding time waste caused by uncoordinated actions between components, and further improving the operating efficiency of the entire device.

[0025] The working principle of the present invention is: When conducting damage assessment on composite material structure samples, the staff starts the bidirectional motor 601 to run forward through the touch screen panel 102, drives the driving gear 602 to rotate, and then drives the driven gear 506, and uses the vertical rod 504 and the curved plate 503 to make the soft brush 5031 wipe the surface of the water bag 303. At the same time, the sealing cover 2 is slowly opened through the magnetic transmission wheel, transmission chain 704 and magnetic coupler 701 to expose the placement slot 101, and then the composite material structure sample is placed in the placement slot 101, and then the pull rod 803 is manually pulled to both sides. The pull rod 803 drives the plug-in block 802 to move and squeezes the support spring 804, canceling the fixation of the plug-in block 802 on the top block 301, and then the staff pinches the top block 301, The ultrasonic probe 302 is pulled out and inserted into the through slot 106, and the water bag 303 at the end of the ultrasonic probe 302 is placed close to the sample surface to ensure the coupling effect. Then, the ultrasonic detection is started. The ultrasonic probe 302 moves at a constant speed along a certain path on the surface of the composite material structure sample, emitting high-frequency ultrasonic waves. The ultrasonic waves propagate inside the composite material and generate reflected waves when encountering interface damage. The reflected waves are received by the probe and converted into electrical signals. The analysis and evaluation module 109 processes these signals, analyzes the phase, amplitude, propagation time and other characteristics of the reflected waves, and determines the location, size and extent of the damage based on these characteristics. Based on the analyzed structure, the severity of the interface damage of the composite material structure is evaluated, and an evaluation report is displayed on the touch screen panel 102; After the assessment is completed, the staff only needs to reinsert the ultrasonic probe 302 into the through slot 106. When the inclined slot 3012 of the top block 301 contacts the inclined surface of the plug-in block 802, the downward movement of the top block 301 will push the plug-in block 802 to move into the storage slot 801 until the slot 3011 is located at the plug-in block 802. Under the elasticity of the supporting spring 804, the plug-in block 802 will be inserted into the slot 3011 to complete the fixation of the ultrasonic probe 302. At this time, the water bag 303 will be located in the center of the three flushing plates 501, and the soft brush 5031 on the curved plate 503 will also contact the surface of the water bag 303. The touch screen panel 102 will be used to start the operation. The water pump 508 in the solvent chamber 103 sprays the solvent onto the surface of the water bag 303 through the liquid supply pipe 507 and the branch pipe. At the same time, the dual-axis motor 601 of the drive assembly 6 works, and one output end drives the driving gear 602 to rotate. The driving gear 602 drives the meshing driven gear 506 to rotate, and then drives the vertical rod 504 to rotate through the attached horizontal rod 505. The vertical rod 504 drives the curved plate 503 and the soft brush 5031 to rotate synchronously. The soft brush 5031 scrubs the surface of the water bag 303 in all directions. The solvent and scrubbing work together to effectively remove stains. Then the water pump 508 in the clean water chamber 104 is started, and clean water rinses away the residual solvent to ensure thorough cleaning. The other output end of the dual-axis motor 601 drives the worm 603 to rotate, and the worm 603 drives the worm wheel 604 to rotate, which drives the first bevel gear 606 to rotate through the transmission shaft 605, and then the second bevel gear 607 rotates synchronously, and the shaft 608 rotates accordingly. The transmission wheel on the shaft 608 drives the horizontal shaft 702 to rotate through the transmission chain 704. The rotation of the horizontal shaft 702 drives the magnetic coupler 701 to work, so that the connecting shaft 705 rotates accordingly, and then drives the sealing cover 2 to rotate through the driving rod, so that the sealing cover 2 can be rotated from vertical to horizontal, effectively covering the placement slot 101. At the same time, after the sealing cover 2 rotates to the horizontal, the magnetic coupler 701 will not hinder the continuous rotation of the horizontal shaft 702, ensuring the continuous cleaning of the surface of the water bag 303. The dirt flushed is discharged with water through the drain port 108, keeping the internal environment of the equipment clean.
