[0028] Example 1, please refer to Figures 1-9This utility model provides the following technical solution: Specifically, it refers to an array-type flexible eddy current sensor, including a body assembly 1, a positioning member 2 slidably fitted on the body assembly 1, the body assembly 1 including a drive control member 3, a socket member 4 electrically connected to the drive control member 3, and flexible eddy current sensors 5 linearly arrayed and fitted onto the socket member 4; the socket member 4 includes a socket body 401, one side of which is provided with a plurality of linearly arrayed insertion holes 402, the plurality of insertion holes 402 respectively connecting to a plurality of flexible eddy current sensors. Sensor 5 is plugged in and engaged; on the other side of the socket body 401, there are several sensor sockets 403 arranged in a linear array. Two symmetrical guide posts 404 are fixed on the top of the socket body 401. Several rectangular plug-in covers 405 are arranged in a linear array on the top of the socket body 401. The several rectangular plug-in covers 405 are respectively connected to several sets of plug-in holes 402. The sensor sockets 403 are plugged in and engaged with the drive control component 3. The positioning component 2 is plugged in and engaged with the several rectangular plug-in covers 405. The positioning component 2 and the two guide posts 404 are slidably engaged through each other.

[0029] Furthermore, the drive control component 3 includes a control body 301, a display screen 302 on the top of the control body 301, and sliding channels 303 fixed on both opposite sides of the control body 301; a plurality of slots 304 are arranged in a linear array on the top and one side of the control body 301, and the plurality of slots 304 are respectively inserted into and cooperate with a plurality of sensor sockets 403; the flexible eddy current sensor 5 includes a sensor body 501, a plurality of thin steel wires 502 are arranged in a linear array on one side of the sensor body 501, and the peripheral sides of the plurality of thin steel wires 502 are provided with downwardly extending positioning locking holes 503, and the thin steel wires 502 are inserted into and cooperate with the insertion holes 402; the positioning component 2 includes a movable frame 2 that slides between the two sliding channels 303. 01. Two symmetrical triangular plates 202 are fixed on the side of the movable frame 201. Sliding rods 203 are slidably fitted on the inclined surfaces of the two triangular plates 202. A top plate 204 is fixed between the two sliding rods 203 and is slidably fitted on the two guide posts 404. Two elastic springs 205 are fixed between the top plate 204 and the socket body 401 and are respectively sleeved on the two guide posts 404. At the bottom of the top plate 204, between the two elastic springs 205, a number of rectangular plug-in posts 206 are fixed in a linear array and are respectively inserted into the interior of a number of rectangular plug-in covers 405. A number of semi-circular grooves 207 are opened at the bottom of the number of rectangular plug-in posts 206. A self-locking locking post 208 is fixed on the inner wall of the semi-circular groove 207 and is inserted into the positioning lock hole 503.

[0030] The specific application of this embodiment is as follows: Before using this array-type flexible eddy current sensor, several thin steel wires 502 arranged in a linear array on one side of the sensor body 501 of the flexible eddy current sensor 5 are simultaneously inserted into a set of insertion holes 402 (the other flexible eddy current sensors 5 are operated in sequence). After the flexible eddy current sensors 5 have been inserted in sequence, the sliding engagement of the moving frame 201 between the two sliding channels 303 causes the moving frame 201 to slowly move away from the inner wall of the slots 304 between the two sliding channels 303. When the moving frame 201 slowly moves away from the inner wall of the slots 304 between the two sliding channels 303, it slides synchronously on the inclined surfaces of the two triangular plates 202 through the two sliding rods 203, so that the spring fixedly connected between the top plate 204 and the socket body 401... The elastic spring 205 is compressed synchronously, causing the top plate 204 to slide slowly downward on the two guide posts 404 (the compressed elastic spring 205 facilitates the top plate 204 to move in opposite directions between the two guide posts 404 when the flexible eddy current sensor 5 is replaced or disassembled later). This causes the rectangular insertion posts 206 fixed in a linear array at the bottom of the top plate 204 to slide inside the rectangular insertion covers 405 respectively, until the circular grooves 207 at the bottom of the rectangular insertion posts 206 are attached to the surface of the thin steel wire 502. Then, the self-locking posts 208 fixed in the inner wall of the semi-circular grooves 207 slide into the positioning lock holes 503, thereby completing the detachable installation and fixing of the flexible eddy current sensor 5, simplifying the installation process of the entire array-type flexible eddy current sensor, and facilitating the replacement of the flexible eddy current sensor 5 that needs to be replaced later.

[0031] Example 2, please refer to Figures 1-9This second embodiment is an improvement on the first embodiment as follows: Specifically, a baffle 306 is fixed to the bottom of the control body 301, a rotating bolt 307 is rotatably fitted to one side of the baffle 306, a first annular plate 308 is fixed to the circumferential side of the rotating bolt 307 and fits against one side of the baffle 306, and a second annular plate 309 is fixed to the end of the rotating bolt 307 and fits against the opposite side of the baffle 306; a moving plate 209 threadedly connected to the rotating bolt 307 is fixed to the top of the moving frame 201; first pins 210 are fixed to both outer sides of the moving frame 201, lifting arms 211 are rotatably fitted to the circumferential sides of both first pins 210, and second pins 211 are rotatably fitted to one side of each lifting arm 211. 12. A U-shaped plate 213 is fixed between the two second pins 212; several inserts 214 are fixed in a linear array inside the bottom of the U-shaped plate 213, which are inserted into the slots 304; a first triangular body 215 is fixed on the top of the inserts 214; two positioning cylinders 216 are fixed inside the bottom of the U-shaped plate 213; a second triangular body 310 is fixed inside the slots 304; a first triangular groove 406 is opened at the bottom of the sensor sockets 403 to engage with the first triangular body 215; a second triangular groove 407 is opened at the top of the sensor sockets 403 to engage with the second triangular body 310; and two guide holes 305 are opened at the top of the control body 301 to slide on the two positioning cylinders 216.

[0032] A specific application of this embodiment is as follows: Before using this array-type flexible eddy current sensor, several sensor sockets 403 on the socket body 401 are simultaneously inserted into several slots 304 provided on the control body 301, so that the first triangular grooves 406 respectively opened at the bottom of the several sensor sockets 403 are simultaneously inserted and snapped into the surface of the first triangular body 215. At this time, the rotating bolt 307 is rotated, which drives the moving plate 209 to move away from the inner wall of the several slots 304, so that the rotational engagement between the first pin 210 and the second pin 212 is achieved. The two lifting arms 211 rotate synchronously, thereby driving the U-shaped plate 213 fixedly connected between the two second pins 212 and the two positioning cylinders 216 fixed at the top of the U-shaped plate 213 to slide inside the two guide holes 305 respectively. This causes the first triangular body 215 fixed at the top of the insertion post 214 to make a vertical linear movement inside the slot 304 until several first triangular bodies 215 slide and engage inside the first triangular groove 406. Then, the rotation of the rotating bolt 307 is stopped, thus completing the installation and positioning work before use, which facilitates its replacement at any time in the future.

[0033] After the array-type flexible eddy current sensor is installed and positioned, firstly, using the handheld control unit 301, the sensor bodies 501 of the multiple flexible eddy current sensors 5 distributed in the array are placed close to the surface of the area to be inspected. During the inspection process, due to the flexibility and elasticity of the thin steel wire 502, the detection surfaces of the multiple sensor bodies 501 can adaptively adhere to the surface of the area to be inspected. Then, the handheld control unit 301 manually drives the drive control component 3 to move and scan the multiple flexible eddy current sensors 5 across the surface of the area to be inspected. During this process, the flexible eddy current sensors... The eddy current signal scanned by the device 5 is transmitted to the signal analysis and processing unit of the drive control unit 3 via the thin steel wire 502 for analysis and processing. The detection result is then output and displayed on the display screen 302 of the drive control unit 3. At the same time, if a defect is found on the surface of the part to be inspected, the drive control unit 3 will issue an alarm. Finally, during the scanning and inspection of the surface of the part to be inspected, once the drive control unit 3 issues an alarm, the operator will read and record the defect information, including the location, size, and depth of the defect, from the display screen 302 on the top surface of the drive control unit 3. In this way, the surface of the part to be inspected can be inspected quickly, accurately, and efficiently.

[0034] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
