Description

Technical Field

[0001] This invention relates to the field of detection technology, and more specifically, to an intelligent ultrasonic testing device with an automatically hovering detection head. Background Technology

[0002] Ultrasonic testing technology is widely used in medical, industrial, commercial, military and even agricultural fields. It achieves technologies such as flaw detection, thickness measurement, distance measurement, remote control and imaging by emitting and receiving reflected ultrasonic waves. Existing ultrasonic testing devices generally include a main unit, a display and an ultrasonic probe. The ultrasonic probe is used to emit and receive ultrasonic waves, the display is used to display the relevant detection information, and the main unit is used for comprehensive processing. The main unit is equipped with a bayonet for daily fixing of the ultrasonic probe.

[0003] As disclosed in CN111358497A, this invention provides an intelligent ultrasonic testing device, including a main unit, a display, and an ultrasonic probe. The main unit has casters at its bottom. The ultrasonic probe includes a housing with a delivery channel for delivering coupling agent and a valve switch for opening and closing the delivery channel. One end of the housing has a detection section for emitting and receiving ultrasonic waves. An annular protrusion is arranged around the edge of the detection section. An outlet for the delivery channel is located at the inner root of the annular protrusion. This intelligent ultrasonic testing device, on the one hand, directly outputs coupling agent from the edge of the detection section, and on the other hand, retains coupling agent in the detection section through the annular protrusion, slowing down the loss rate of the coupling agent. These two measures ensure that the detection section and the skin are always filled with coupling agent, eliminating the need for the operator to forcefully squeeze the ultrasonic probe, making operation more convenient and improving the experience for the person being tested.

[0004] In the current ultrasound testing process, when it is necessary to briefly stop the movement of the ultrasound probe for precise measurement or observation, the probe cannot be automatically hovered and must be manually fixed. This not only increases the workload of doctors, but also causes the position of the ultrasound probe to shift due to human factors, thus affecting the accuracy and stability of the test results. In addition, existing ultrasound testing devices have difficulty in accurately controlling the pressure of the ultrasound probe against the human skin for safe contact, which further affects the accuracy and comfort of the test.

Dovetail grooves 628 are fixedly connected to both the front and rear ends of fixing rod 627. The inner wall of dovetail grooves 628 is movably connected to the outer wall of trapezoidal plate 614. Fixing plates 629 are fixedly connected to the bottom of the two dovetail grooves 628. The lower sides of the two fixing plates 629 are fixed on the side closest to each other. The device is connected to two insert plates 620. A second fixing plate 6201 is provided on the outer wall of each insert plate 620. Connecting grooves 6202 are provided on both the left and right sides of the top of the second fixing plate 6201. Positioning slots 6203 are provided below each of the two connecting grooves 6202 on their closest sides. The inner wall of the positioning slot 6203 is movably connected to the outer wall of the insert plate 620. The inner wall of the connecting groove 6202 is movably connected to the outer wall of the first fixing plate 629. An ultrasonic testing probe 6204 is fixedly connected to the bottom of the second fixing plate 6201. When the first fixing rod 201 is moved upward, the second limiting post 20 drives the third connecting plate 29 to move upward. The third connecting plate 29 drives the first limiting post 28 and the fixing sleeve 27 to move upward. The fixing sleeve 27 then drives the fixing groove body... 25 causes the left ends of connecting plate 26 and connecting plate 24 to swing within the inner wall of mounting groove 22. The swinging of connecting plate 24 causes the rotating rod 23 to rotate, which in turn drives gear 31 to rotate. Gear 31 rotates, causing sector gear 32 to rotate.

When the ultrasonic detection probe 6204 needs to be disassembled for maintenance or replacement, simply reverse the operation of the fixing rod 201 to move it downward, so that the insert 611 is inserted into the inner wall of the slot 42. Then, the top block 43 inserts into the corresponding slot 615, and then the top block 43 pushes the top plate 623 upward. The top plate 623 drives the sliding sleeve 624 to move upward along the sliding rod 625 and compress the return spring 626. At the same time, the top plate 623 drives the movable block 621 to move upward in the mounting groove 612. The movement of the movable block 621 causes the fixed inclined hole 622 to change position relative to the fixing rod 627, thereby driving the dovetail groove 628 to move along the... Trapezoidal plate 614 moves outward, and dovetail groove 628 drives fixed plate 629 to move outward. Fixed plate 629 drives insert plate 620 to be pulled out of positioning slot 6203. At this time, fixed plate 6201, along with ultrasonic testing probe 6204, can be removed from the bottom of insert block 611 for maintenance or replacement. After maintenance or replacement, fixed plate 6201 is placed back in the appropriate position, aligning insert plate 620 with positioning slot 6203. Then, fixed rod 201 is operated forward to move it upward. Through a series of linkage structures, top plate 623 is reset under the action of return spring 626, thereby resetting all components. Insert plate 620 is reinserted into positioning slot 6203, achieving a stable installation of ultrasonic testing probe 6204. The entire disassembly and installation process is convenient and quick, effectively improving the maintenance efficiency and ease of use of the device.

The bottom of pressure sensor 527 is fixedly connected to the top of insert block 611. By starting stepper motor 513, stepper motor 513 drives lead screw 514 to rotate. The rotation of lead screw 514 drives slider 515 to move up and down in left mounting slot five 512. The movement of slider 515 drives extension plate 518 to move up and down. The movement of extension plate 518 drives sliding sleeve two 517 to slide on the outer wall of sliding rod two 516, improving the stability of extension plate 518 during movement. The movement of extension plate 518 drives fixed seat 519, connecting seat one 510 and... The buffer assembly 52 is finely adjusted vertically to precisely adjust the height of the ultrasonic probe 6204, meeting the precise height requirements of different testing scenarios. During the ultrasonic probe 6204's testing operation, when it presses down to contact the human skin, the pressure sensor in the buffer assembly 52 monitors the pressure value in real time. If the pressure exceeds a preset safety threshold, the stepper motor 513 will immediately stop operating. Simultaneously, the pressure generated when the ultrasonic probe 6204 contacts the human skin will cause the buffer spring 525 to slide on the outer wall of the slide bar 523 through the fixed frame 526. Consequently, the buffer spring 525 is compressed and undergoes elastic deformation, buffering and absorbing the pressure.To avoid excessive pressure on the skin caused by the 6204 ultrasonic probe, thus ensuring the safety and comfort of the testing process.

[0024] Working principle of this invention: When the fixed rod 201 is moved upward, the limiting post 20 drives the connecting plate 29 to move upward. The connecting plate 29 drives the limiting post 28 and the fixing sleeve 27 to move upward. The fixing sleeve 27 will drive the fixing groove 25, causing the left ends of the connecting plate 26 and the connecting plate 24 to swing on the inner wall of the mounting groove 22. The swinging of the connecting plate 24 causes the rotating rod 23 to rotate, which in turn drives the gear 31 to rotate. The rotation of the gear 31 drives the sector gear 32 to rotate. The sector gear 32 drives the connecting plate 33 to swing. The connecting plate 33 pushes the connecting plate 34 to drive the counterweight 35 to slide in the mounting groove 202, so that the ladder on its rear side... The groove 36 slides along the outer wall of the trapezoidal plate 203, while the tension spring 38 is stretched. When the fixing rod 201 moves to the appropriate position, it stops moving. At this point, the detection head can automatically hover at this height for ultrasonic testing. The limiting post 20 rotates on the inner wall of one end of the connecting plate 29, the limiting post 28 rotates on the inner wall of the fixing sleeve 27, and the support post 21 rotates on the top of the fixed platform 1. This allows the device to flexibly adjust the detection angle and position of the detection head to adapt to different testing scenarios. When the ultrasonic testing probe 6204 needs to be disassembled for maintenance or replacement, simply reverse the operation of the fixing rod 201 to move it downwards. Insertion block 611 is inserted into the inner wall of slot 42, and then top block 43 is inserted into slot 615. Top block 43 then pushes top plate 623 upward. Top plate 623 drives sliding sleeve 624 to move upward along sliding rod 625 and compresses return spring 626. At the same time, top plate 623 drives movable block 621 to move upward in mounting groove 612. The movement of movable block 621 causes the fixed oblique hole 622 to change position relative to fixed rod 627, thereby driving dovetail groove 628 to move outward along trapezoidal plate 614. Dovetail groove 628 drives fixed plate 629 to move outward. Fixed plate 629 drives insertion plate 620 to be pulled out from positioning slot 6203. At this point, the fixing plate 6201, along with the ultrasonic testing probe 6204, can be removed from the bottom of the insert block 611 for maintenance or replacement. After maintenance or replacement, the fixing plate 6201 is placed back in the appropriate position, aligning the insert plate 620 with the positioning slot 6203. Then, the fixing rod 201 is moved upwards in a forward direction. Through a series of linkage structures, the top plate 623 is reset under the action of the reset spring 626, thereby driving the components to reset. The insert plate 620 is reinserted into the positioning slot 6203, achieving a stable installation of the ultrasonic testing probe 6204. The entire disassembly and installation process is convenient and quick, effectively improving the maintenance efficiency and ease of use of the device. By activating the stepper motor 513, the stepper motor 513 drives the lead screw 514 to rotate. The rotation of the lead screw 514 causes the slider 515 to move up and down within the left mounting slot 512. The movement of the slider 515 causes the extension plate 518 to move up and down. The movement of the extension plate 518 causes the sliding sleeve 517 to slide against the outer wall of the sliding rod 516, improving the stability of the extension plate 518 during movement. The movement of the extension plate 518 also causes the fixed base 519, connecting base 510, and buffer assembly 52 to be finely adjusted up and down as a whole, thereby achieving precise adjustment of the height of the ultrasonic testing probe 6204 to meet the precise height requirements of different testing scenarios. During the detection process of the ultrasonic probe 6204, when the ultrasonic probe 6204 presses down to contact the human skin, the pressure sensor in the buffer component 52 will monitor the pressure value in real time. If the pressure exceeds the preset safety threshold, the stepper motor 513 will stop running immediately. At the same time, the pressure generated when the ultrasonic probe 6204 contacts the human skin will drive the buffer spring 525 to slide on the outer wall of the slide bar 523 through the fixed frame 526. As a result, the buffer spring 525 is compressed and produces elastic deformation, which buffers and absorbs the pressure, avoiding excessive compression of the human skin by the ultrasonic probe 6204, thereby ensuring the safety and comfort of the detection process.
