[0032] Working principle: Place the bottom plate 1 and the device body 2 on the wall surface to be inspected, and then turn on the linear drive component 10. The linear drive component 10 is turned on to push out the output rod 100 and drive the output rod 100 to move upward. The upward movement of the output rod 100 drives the device body 2 to move upward as a whole until the scraper plate 48 moves to the inspection position of the wall surface to be inspected. At this time, the control center 41 is used to turn on the second rotary drive component 471. The second rotary drive component 471 is turned on to drive the second rotating shaft 472 to rotate. The rotation of the second rotating shaft 472 drives the rotating disk 473 to rotate. The rotation of the rotating disk 473 drives the second rotating rod 474 to rotate. The rotation of the second rotating rod 474 drives the second return groove plate 475 to move. Since the top of the second return groove plate 475 is supported by the third shaft 476 The movement of the second return groove plate 475 drives the toothed disc 477 to make a reciprocating swinging motion, and the movement of the toothed disc 477 drives the toothed plate 478 to make a linear reciprocating motion. The telescopic plate 441 is used to limit the movement of the toothed plate 478. The movement of the toothed plate 478 drives the scraping plate 48 to scrape the detection position of the wall surface to be detected through the connecting frame 480 and the through groove 470. The scraping treatment of the scraping plate 48 will clean up the peeling putty, white hair, hard blocks and other debris on the wall surface to be detected, so as to avoid the detection device 40 from being affected by the sound wave transmission emitted by the detection head 401 when the detection device 40 is left on the wall, thereby reducing the accuracy of the detection result of the detection device 40, improving the detection effect of the device and the accuracy of the detection result, and facilitating user use; When the above steps are running, the control center 41 is used to turn on the first rotation drive component 30, and the first rotation drive component 30 is turned on to drive the first rotating shaft 31 to rotate, and the first rotating shaft 31 rotates to drive the first bevel gear 32 to rotate, and the first bevel gear 32 rotates to drive the second bevel gear 422 to rotate, and the second bevel gear 422 rotates to drive the through rod 42 to rotate, and the through rod 42 rotates to drive the two worms 420 to rotate, and the worm 420 rotates to drive the worm wheel 431 to rotate, and the worm wheel 431 rotates to drive the second shaft rod 430 to rotate, and the second shaft rod 430 rotates to drive the screw 434 and the adjusting arm 432 to rotate, and the adjusting arm 432 rotates to drive the first rotating rod 433 to do a circular motion, and the first rotating shaft 31 rotates to drive the first bevel gear 422 to rotate, and the second bevel gear 422 rotates to drive the second bevel gear 422 to rotate, and the first ... first bevel gear 422 to rotate, and the first bevel The movement of the rod 433 drives the first return groove plate 44 to make a linear reciprocating motion, and the movement of the first return groove plate 44 drives the movable plate 440 to make a linear reciprocating motion on the top of the telescopic plate 441. The movement of the movable plate 440 drives the grinding plate 443, the spraying plate 444, and the processing chamber 47 to make a linear reciprocating motion through the fixed rod 442 and the movable groove. The movement of the processing chamber 47 enables the scraping plate 48 to perform a comprehensive scraping treatment on the detection position of the wall surface that needs to be detected from bottom to top. The grinding plate 443 moves from bottom to top to smooth the rough surface of the wall surface after being scraped by the scraping plate 48, thereby expanding the processing range of the device and further reducing the influence of wall debris on the transmission of sound waves, thereby improving the detection effect of the device and the accuracy of the detection results, and facilitating user use; In the above steps, the screw rod 434 rotates to drive the movable rod 450 to make a linear motion close to the storage bin 45. The movement of the movable rod 450 drives the piston plate 451 to move inside the storage bin 45. The movement of the piston plate 451 causes the air pressure inside the storage bin 45 to change. At this time, the water inside the storage bin 45 is transported to the delivery bin 456 through the delivery pipe 454, and then the delivery bin 456 delivers the water to the spray plate 444 through the delivery pipe 457. The first one-way valve 453 is used to prevent water from flowing back into the containing bin 46. At this time, the scraping plate 48, the spray plate 444, and the polishing plate 443 are in the process of moving up. The nozzle inside the spray plate 444 sprays water to the detection position of the wall that needs to be detected. At this time, the movement of the polishing plate 443 can wipe off the oil and putty mixed with water on the wall, further reducing the influence of wall debris on the transmission of sound waves. The first rotating shaft 31 rotates in the opposite direction, and the first rotating shaft 31 rotates in the opposite direction. The reverse rotation of the first rotating shaft 31 can reset the scraping plate 48, the spraying plate 444, and the grinding plate 443 in the same way as above, and the piston plate 451 is also reset in the storage bin 45. The movement of the piston plate 451 causes the air pressure inside the storage bin 45 to change again. At this time, the water inside the storage bin 46 enters the storage bin 45 through the extraction pipe 452. The second one-way valve 455 is used to prevent the water at the spraying plate 444 from flowing back into the storage bin 45. The storage bin 45 is filled with water again, waiting for the next upward movement of the scraping plate 48, the spraying plate 444, and the grinding plate 443. The device can minimize the influence of wall debris on the transmission of sound waves, improve the detection effect of the device and the accuracy of the detection results, and facilitate user use. After the processing device 4 is cleaned, the control center 41 is used to start the linear drive assembly 10, and the linear drive assembly 10 retracts the output rod 100 and drives the output rod 100 to move downward. The output rod 100 moves downward, driving the drive device 3 and the processing device 4 to move downward until the two detection heads 401 are at the detection position of the wall that needs to be detected. Then, the telescopic tube 400 is pulled to make the detection head 401 close to the detection position of the wall that needs to be detected for acoustic wave detection, thereby completing the crack detection of the building wall.
