A sewage outlet 376 is provided at the lower end of the cleaning cover 371, and a monitoring head group opening 377 is provided on the left side of the cleaning cover 371. A high-pressure air pipe 378 is connected to the right end of the second air inlet pipe 374, and an air compressor is externally connected to the other end of the high-pressure air pipe 378.

[0029] The alarm terminal 32 is composed of a housing 321 , a sound wave sensor display 322 , a control switch 323 and an alarm 324 .

[0030] Working principle: The monitoring alarm method is to first drive the screw 343 to rotate at the screw mouth 345 through the first motor 344 on the telescopic arm group 34, so that the telescopic arm 342 slides laterally in the direction of the gear group 2 in the first slide seat 341, and push the monitoring head group 36 to the left to the front position of the gear group 2, and then extend the telescopic device 352 on the rotating arm group 35 to push the square slide bar 3512 to the left, so that the rack 3513 drives the gear 3533 to rotate, and the swing arm body 3534 is turned 180 degrees to the left through the rotating shaft 3532, so that the anti-fouling cap 364 will turn back to the gear group 2 meshing position. 5-6mm in front of the meshing point, and the rear side of the swing arm body 3534 will be magnetically connected to the magnet block 348 to reinforce and stabilize the positioning of the swing arm body 3534. Because the acoustic emission sensor 363 can be as close to the meshing point of the gear set 2 as possible, the high-frequency stress wave released by the damaged teeth on the gear set 2 during meshing will pass through each sound receiving hole 365 and be accurately captured by the acoustic emission sensor 363, and transmit the signal to the acoustic wave sensor display 322 for display. At the same time, the stress wave generated by the damaged teeth on the gear will be alerted through the alarm 324.

[0031] It should be noted that only when the acoustic emission sensor 363 is as close to the meshing part of the gear set 2 as possible, the acoustic emission sensor 363 can capture stress sound waves more accurately and is less likely to be disturbed by other sound waves of the equipment. However, if the acoustic emission sensor 363 is not protected by the anti-fouling shell 362, it is easy to be stuck to the oil on the teeth, thereby affecting the performance of the acoustic emission sensor 363, and it is not convenient to automatically clean the acoustic emission sensor 363. When the anti-fouling cap 364 is stuck to the oil, because the various sound collecting holes 365 are tilted downward, the oil is not easy to completely block the various sound collecting holes 365, and it is only necessary to clean the anti-fouling cap 364 regularly.

[0032] In addition, the left and right telescopic function design of the telescopic arm group 34 can also make it possible to maintain the gear group 2 without removing the monitoring end 31, and the gear group 2 will not be stuck by the monitoring head group 36 and cannot be removed.

[0033] Cleaning method: first, the monitoring head group 36 is rotated 180° to the right by the rotating arm group 35, so that the anti-fouling cap 364 is turned outward to the front. At this time, the first support column sleeve 367 and the first support column 346 are movably fitted and positioned, and then the telescopic arm group 34 is retracted to the right horizontally to make the monitoring head group 36 slide to the right through the telescopic opening 332 and the monitoring head group opening 377. At this time, the anti-fouling cap 364 and the brush on the brush plate 373 are flexibly offset by 1-2mm, and the first air inlet pipe 366 is It is connected to the second air inlet pipe 374 through a sealing soft sleeve 375, and then the second motor 372 drives the brush plate 373 to rotate and scrape the oil on the surface of the anti-fouling cap 364, and simultaneously adds high-pressure gas through the air compressor. The gas enters the cavity of the anti-fouling shell 362 through the high-pressure gas pipe 378, the first air inlet pipe 366, the second air inlet pipe 374, and the sealing soft sleeve 375, and blows out the oil stuck in the aperture of each sound collecting hole 365 from the inside to the outside, and the cleaned oil is discharged downward from the drain port 376.

[0034] It should be noted that the main purpose of the anti-blocking cleaning group 37 is to ensure that the oil stains stuck on the monitoring head group 36 can be automatically and regularly cleaned in the cavity of the spinning frame body 1. The user does not need to manually remove the outer shell of the spinning frame body 1 to manually clean the monitoring head group 36, which makes the operation simpler and more efficient.

[0035] In addition, the movable connection design between the first air inlet pipe 366 and the second air inlet pipe 374 and the sealing soft sleeve 375 reduces the design of the exhaust pipe, making the left and right flipping of the monitoring head group 36 more flexible, compared with the direct connection of the first air inlet pipe 366 to the high-pressure air pipe 378.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
