[0045] Working principle: Place the bottom plate 1 and the equipment main body 2 at the wall surface to be detected. Then, turn on the linear drive assembly 10. When the linear drive assembly 10 is turned on, it will 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 entire equipment main body 2 to move upward until the scraping plate 48 moves to the detection site of the wall surface to be detected. At this time, use the control center 41 to turn on the second rotary drive assembly 471. When the second rotary drive assembly 471 is turned on, it drives 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 limited by the third shaft rod 476, at this time, the second return groove plate 475 can only make a reciprocating swing motion. The movement of the second return groove plate 475 drives the gear disk 477 to make a reciprocating swing motion. The movement of the gear disk 477 drives the gear plate 478 to make a linear reciprocating motion. The telescopic plate 441 is used to limit the movement of the gear plate 478. The movement of the gear plate 478 drives the scraping plate 48 to scrape the detection site 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 clears the putty, white hair, hard lumps and other sundries that are peeling off at the wall surface to be detected, preventing the sound waves transmitted by the detection head 401 of the detection device 40 from being affected when they remain on the wall surface, 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 the user to use;

[0046] When the above steps are running, the control center 41 is used to activate the first rotation drive assembly 30. The activation of the first rotation drive assembly 30 drives the first rotating shaft 31 to rotate. The rotation of the first rotating shaft 31 drives the first bevel gear 32 to rotate. The rotation of the first bevel gear 32 drives the second bevel gear 422 to rotate. The rotation of the second bevel gear 422 drives the through rod 42 to rotate. The rotation of the through rod 42 drives the two worm gears 420 to rotate. The rotation of the worm gears 420 drives the worm wheels 431 to rotate. The rotation of the worm wheels 431 drives the second shaft rod 430 to rotate. The rotation of the second shaft rod 430 drives the screw rod 434 and the adjusting arm 432 to rotate. The rotation of the adjusting arm 432 drives the first rotating rod 433 to perform a circular motion. The movement of the first rotating rod 433 drives the first return groove plate 44 to perform a linear reciprocating motion. The movement of the first return groove plate 44 drives the movable plate 440 to perform 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 treatment chamber 47 to perform a linear reciprocating motion through the fixed rod 442 and the movable groove. The movement of the treatment chamber 47 enables the scraping plate 48 to perform a comprehensive scraping treatment on the detection site of the wall surface to be detected from bottom to top. The upward movement of the grinding plate 443 levels the rough surface of the wall surface after being scraped by the scraping plate 48, expanding the treatment range of the device while further reducing the influence of wall surface debris on the sound wave transmission effect, improving the detection effect of the device and the accuracy of the detection results, and facilitating the use of the user;

[0047] In the above steps, the rotation of the screw rod 434 drives the movable rod 450 to move linearly towards 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 through the delivery pipe 454 to the delivery bin 456, and then the delivery bin 456 transports the water through the transport pipe 457 to the spraying plate 444. The first one-way valve 453 is used to prevent the water from flowing back into the receiving bin 46. At this time, the scraping plate 48, the spraying plate 444, and the grinding plate 443 are moving upward. The nozzles inside the spraying plate 444 spray the water to the detection sites of the wall to be detected. At this time, the movement of the grinding plate 443 can wipe off the oil stains mixed with water and the putty mixed with water on the wall surface, further reducing the influence of wall surface debris on the sound wave transmission effect. Subsequently, the control center 41 controls the first rotation drive assembly 30 to drive the first rotating shaft 31 to rotate in the reverse direction. At this time, the reverse rotation of the first rotating shaft 31 can, by the same token as above, cause the scraping plate 48, the spraying plate 444, and the grinding plate 443 to return to their original positions, and the piston plate 451 also returns to its original position inside 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 receiving 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 refilled with water and waits for the next upward movement of the scraping plate 48, the spraying plate 444, and the grinding plate 443 for use. Thus, the device can minimize the influence of wall surface debris on the sound wave transmission effect, improve the detection effect of the device and the accuracy of the detection result, and facilitate the use of the user;

[0048] After the cleaning of the processing device 4 is completed, the control center 41 is used to activate the linear drive assembly 10. The linear drive assembly 10 retracts the output rod 100 and drives the output rod 100 to move downward. The downward movement of the output rod 100 drives the drive device 3 and the processing device 4 to move downward until the two detection heads 401 are at the detection sites of the wall to be detected. Then, the telescopic tube 400 is pulled to press the detection heads 401 tightly against the detection sites of the wall to be detected for sound wave detection, and the crack detection of the building wall is completed.
