[0043] When the display screen 201 has a poor effect of monitoring ultrasound, the display screen 201 issues an alarm, and the staff further places the support column 6 into the pipe to be tested 1. At this time, the multiple moving wheel support rods 7 extend, so that the multiple moving wheels 701 move outward, so that the multiple moving wheels 701 are in close contact with the inner wall of the pipe to be tested 1, thereby ensuring the stability of the support column 6. At this time, due to the action of the antenna 603, the display screen 201 can control the internal controller 601 to work. At this time, the internal controller 601 controls the camera 604 to work, so as to monitor the internal situation of the pipe to be tested 1. Further, the internal controller 601 controls the multiple moving wheel motors 703 to work in coordination, thereby driving the multiple moving wheels 701 to rotate, so that the support column 6 moves along the pipe to be tested 1, so as to monitor whether there is a lot of dirt on the inner wall of the pipe to be tested 1. When the support column 6 moves to the position close to the monitoring When the upper shell 2 of the device is parallel, the internal controller 601 controls the multiple support motors 706 to work, thereby driving the multiple support bars 705 to rotate, thereby driving the multiple support blocks 704 to rotate until they are close to the inner wall of the pipeline to be tested 1, thereby ensuring the stability of the support column 6.

[0044] The working process of the present invention is as follows: when using the device, the staff places the front fixing belt 4 and the rear fixing belt 401 outside the pipeline to be tested 1, and further the display screen 201 controls the reversing motor 402 to work, thereby driving the front fixing belt 4 and the rear fixing belt 401 to rotate, so that the front fixing belt 4 and the rear fixing belt 401 are close to the pipeline to be tested 1, at this time the display screen 201 controls the reversing motor 402 to lock, thereby preventing the front fixing belt 4 and the rear fixing belt 401 from rotating, and further the staff connects the device to an external power supply through the connecting line 203, thereby ensuring the stability of the device operation, and further the display screen 201 controls the support rod 501 to retract, thereby bringing The support plate 5 is driven to move, thereby driving the gear rod 503 to be close to the outer wall of the pipeline 1 to be measured, and further the display screen 201 controls the gear rod motor 504 to work, thereby driving multiple gear rods 503 to rotate around the pipeline 1 to be measured, so that the monitor upper shell 2 can be reversed, so that the equipment can monitor any position outside the pipeline 1 to be measured, so that the sediment content in different directions of the top and bottom of the pipeline 1 to be measured can be monitored, thereby ensuring the monitoring accuracy. When the monitor upper shell 2 is rotated to the required angle, the display screen 201 controls the gear rod motor 504 to reset, and further the display screen 201 controls the reversing motor 402 to work again, so that the front fixing belt 4 and the rear fixing belt 401 are The pipe to be measured is closely attached, and further the display screen 201 controls the moving rod 404 to extend, thereby driving the moving plate 405 to move downward, thereby causing the locking shaft 406 to move downward, thereby causing the lower end of the rear fixing belt 401 to be closely attached to the front fixing belt 4, and further the display screen 201 controls the locking motor 408 to work, thereby driving the locking plate 407 to rotate, thereby causing the locking plate 407 to be snapped into the slot of the locking shaft 406, thereby preventing the locking shaft 406 from moving in the opposite direction, and at the same time, due to the action of the locking plate 407, the front fixing belt 4 is prevented from being separated from the rear fixing belt 401, thereby ensuring the stability of the monitor upper shell 2. When the monitor upper shell 2 is installed in place, the worker The staff tightens the limit screw 206 to fix the ultrasonic detector 210. The staff further connects the device to the external device through the connecting line 203, so that the device can be remotely controlled. At this time, the monitoring work begins. When water and sediment flow through the inside of the pipeline 1 to be tested, the multiple acoustic wedges 211 can receive ultrasonic waves at multiple points, thereby improving the monitoring accuracy. Furthermore, each piezoelectric ceramic piece 213 of the ultrasonic detector is affected by the ultrasonic signal to generate an electrical signal. After filtering and amplification, it is concentrated in the processing module 208 through the ultrasonic detector electrode piece 212 for processing. It can be judged whether the sediment content and particle size are too large. Each time it is judged, the sediment content and particle size are updated on the display screen 201.If the sediment content and particle size are within the set alarm value, the indicator light 202 lights up green once, and the alarm 3 does not alarm. If the sediment content and particle size exceed the set alarm value, the indicator light 202 lights up red and flashes for five seconds. At this time, due to the action of the alarm electrode piece 305, the alarm piezoelectric ceramic piece 304 and the metal vibrator 303, the alarm 3 sounds for five seconds, and the signal is transmitted to the online remote end in real time. The staff can know the sediment characteristics in the pipeline even if they are not on site, thereby ensuring monitoring accuracy and monitoring efficiency, thereby ensuring monitoring effect. When the display screen 201 monitors the ultrasonic effect poorly , the display screen 201 issues an alarm, and the staff further places the support column 6 into the pipe to be tested 1. At this time, the multiple moving wheel support rods 7 extend, so that the multiple moving wheels 701 move outward, so that the multiple moving wheels 701 are in close contact with the inner wall of the pipe to be tested 1, thereby ensuring the stability of the support column 6. At this time, due to the effect of the antenna 603, the display screen 201 can control the internal controller 601 to work. At this time, the internal controller 601 controls the camera 604 to work, so as to monitor the internal situation of the pipe to be tested 1. Further, the internal controller 601 Control multiple moving wheel motors 703 to work together, thereby driving multiple moving wheels 701 to rotate, so that the support column 6 moves along the pipeline to be tested 1, so as to monitor whether there is a lot of dirt on the inner wall of the pipeline to be tested 1. When the support column 6 moves to be parallel to the upper shell 2 of the monitor, the internal controller 601 controls multiple support motors 706 to work, thereby driving multiple support bars 705 to rotate, thereby driving multiple support blocks 704 to rotate to be close to the inner wall of the pipeline to be tested 1, thereby ensuring the stability of the support column 6. At this time, the internal controller 601 controls the cleaning knife support rod 8 and the cleaning disk support rod 9 extend, so that the cleaning knife 801 and the cleaning wire 902 are closely attached to the pipeline 1 to be tested. At this time, the internal controller 601 controls the cleaning motor 606 to work, thereby driving the cleaning block 605 to rotate, thereby driving the cleaning knife support rod 8 and the cleaning disk support rod 9 to rotate around the cleaning block 605, thereby cleaning the dirt on the inner wall of the pipeline 1 to be tested. Further, the internal controller 601 controls the support column 6 to move out of the pipeline 1 to be tested, and further, the display screen 201 resumes monitoring work, thereby ensuring monitoring accuracy and thus ensuring monitoring effect.
