[0039] According to an optional implementation of the present invention, the data preprocessing module includes a noise removal module. The noise removal module can remove noise from the vibration data.

[0040] According to an optional implementation of the present invention, the data preprocessing module includes a feature extraction module. The feature extraction module can extract features of the vibration data, and the features of the vibration data include vibration amplitude.

[0041] Implementation process: The device to be diagnosed is a pump body 2 , to which a pump pipeline 3 is fixedly connected. The pump body 2 may be any pump used in an oil field, and the diagnostic device is installed beside the pump body 2 .

[0042] When the diagnostic device is in the initial state, the bottom wall of the movable column 7 and the top wall of the first supporting plate 29 are against each other, the movable column 7 is located on the left inner wall of the diagnostic device 1, the detection contact 18 and the left wall of the pump body 2 are against each other, and the vibration data acquisition module obtains the vibration data in real time through the detection contact 18. When the vibration amplitude of the vibration data is suddenly equal to or greater than the preset value, the single-chip microcomputer controls the motor 9 to start, and the vibration data at this time is recorded as the initial vibration data.

[0043] The motor 9 drives the active spur gear 8 to rotate, and the active spur gear 8 meshes with the transmission gear 6, so that the movable column 7 and the components on the movable column 7 slide along the inner wall of the diagnostic device 1. When the movable column 7 moves, the vibration data obtained by the vibration data acquisition module is recorded as dynamic vibration data.

[0044] When the permanent magnetic strip 19 moves to the side of the fifth permanent magnetic plate 5 on the left, the fifth permanent magnetic plate 5 on the left magnetically attracts the permanent magnetic strip 19, so that the detector 17 and the detection contact 18 overcome the elastic force of the second elastic member 16 and move toward the fixed plate 15, and the detection contact 18 is separated from the outer wall of the pump body 2 to prevent the detection contact 18 from being stuck at the upper left corner of the pump body 2 when turning. The movable column 7 continues to move to the inner top wall of the diagnostic device 1. After the permanent magnetic strip 19 loses the magnetic force of the left curved surface 4, the detector 17 and the detection contact 18 are reversed and reset under the elastic force of the second elastic member 16 , the detection contact 18 and the top wall of the pump body 2 are against each other. When the permanent magnetic strip 19 moves to the side of the fifth permanent magnetic plate 5 on the right, the fifth permanent magnetic plate 5 on the right magnetically attracts the permanent magnetic strip 19, and the detector 17 and the detection contact 18 move toward the fixed plate 15, and the detection contact 18 is separated from the top wall of the pump body 2 to prevent the detection contact 18 from being stuck at the upper right corner of the pump body 2 when turning. After the permanent magnetic strip 19 loses the magnetic force of the right curved surface 4, the detector 17 and the detection contact 18 are reversed and reset under the elastic force of the second elastic member 16, and the detection contact 18 and the right wall of the pump body 2 are against each other.

[0045] When the movable column 7 and the second supporting plate 30 are against each other, one of the first permanent magnet plates 20 will move to the same horizontal plane as the third permanent magnet plate 22 and the second supporting plate 30 will press the second reversal button 32. The first permanent magnet plate 20 will move forward under the magnetic adsorption of the third permanent magnet plate 22 in front of it to resist the third permanent magnet plate 22 in front of it, so that the buffer plate 14 moves forward along the movable column 7, and the detection contact 18 moves forward along the right wall of the pump body 2. When the second supporting plate 30 is pressed, the single chip machine controls the motor 9 to reverse, so that the movable column 7 moves in the opposite direction along the original path. The movable column 7 is moved to resist the first supporting plate 29 using the similar principle mentioned above. The other first permanent magnet plate 20 will move to the same horizontal plane as the second permanent magnet plate 21 and the first supporting plate 29 will press the first reversal button 31, so that the single chip machine controls the motor 9 to reverse, and this is repeated to move the detection contact 18 forward step by step.

[0046] When a first permanent magnet plate 20 of the buffer plate 14 moves to the rear of the fourth permanent magnet plate 23, the fourth permanent magnet plate 23 will magnetically adsorb the first permanent magnet plate 20 to complete the magnetic connection, and the detection contact 18 moves to abut against the pump pipeline 3 under the elastic force of the second elastic member 16. At this time, the single-chip microcomputer controls the electromagnet 13 to be energized, and the electromagnet 13 is energized to generate magnetic force to magnetically adsorb the permanent magnet block 10. The motor 9 and the active spur gear 8 overcome the elastic force of the first elastic member 11 and move toward the electromagnet 13, so that the active spur gear 8 and the second spur gear 27 are meshed, and the active spur gear 8 and the transmission tooth 6 are disengaged. The active spur gear 8 drives the second spur gear 27 and the threaded rod 26 to rotate, and the threaded rod 26 drives the slide 24, the fourth permanent magnet plate 23, and the buffer plate 14 to move forward, so that the detection contact 18 moves on the pump pipeline 3 to obtain vibration data on the pump pipeline 3, so as to diagnose whether there is abnormal vibration in the pump pipeline 3.

[0047] The self-learning module can record the initial vibration data, and can also record the number of revolutions of the motor 9 rotor corresponding to each dynamic vibration data, the number of times the first reverse button 31 and the second reverse button 32 are pressed, and the position of the detection contact 18 on the pump body 2 can be calculated by using the number of revolutions of the motor 9 rotor and the number of times the first reverse button 31 and the second reverse button 32 are pressed, so as to know which position on the pump body 2 has the largest vibration amplitude of the dynamic vibration data, which means that the vibration degree of this position on the pump body 2 is the largest, so that the user can quickly know the abnormal vibration of the pump body 2, and then the AI ​​module updates the model.

[0048] According to the model updated by the AI ​​module, the next time the same initial vibration data is obtained, the prediction module can analyze the position range on the pump body 2 where the dynamic vibration data with the largest vibration amplitude is located during the vibration of the pump body 2. This position range is recorded as the predicted vibration source position range, so that before the detection contact 18 reaches the predicted vibration source position range, the single-chip microcomputer controls the motor 9 to rotate at a faster speed so that the detection contact 18 reaches the predicted vibration source position range of the pump body 2 as soon as possible. Before the detection contact 18 approaches the predicted vibration source position range, the single-chip microcomputer controls the motor 9 to reduce its rotor speed, so that the detection contact 18 can more accurately obtain the dynamic vibration data at the position with the maximum vibration amplitude.

[0049] The present invention can diagnose in real time whether the pump body 2 has abnormal vibration through the detection contact 18, and can drive the detection contact 18 through a motor 9 to perform multi-directional vibration diagnosis and detection on the two side walls and the top wall of the pump body 2, so that the user can know in advance which position of the pump body 2 has the most serious vibration before rushing to the pump body 2 for maintenance, and predict in advance which position of the components may be damaged, and bring corresponding components and tools for maintenance in advance. The motor 9 can also drive the detection contact 18 to perform multi-directional vibration diagnosis on the pump pipeline 3 on the pump body 2, comprehensively diagnose the pump body 2, and improve the diagnosis quality and maintenance efficiency; the AI ​​module can perform intelligent diagnosis, predict in advance the position of the pump body 2 with the highest vibration level, and improve the diagnostic efficiency of the device.

[0050] The components, modules, mechanisms and devices not described in detail in the present invention are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
