Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] The ferromagnetic wear debris analysis and detection mechanism provided in this embodiment is used to detect the ferromagnetic wear debris content in an oil sample.

[0043] like Figure 1 , Figure 2As shown, a specific implementation of the ferromagnetic wear debris analysis and detection mechanism provided in this embodiment includes: a reference box 5, a sample box 6, a detection device 4 and a moving assembly, wherein the reference box 5 is used to accommodate a reference oil sample; the sample box 6 is suitable for accommodating a sample oil sample; the detection device 4 has an electromagnetic coil for detecting ferromagnetic wear debris; the moving assembly connects the reference box 5 and the sample box 6, and the moving assembly is used to drive the reference box 5 and the sample box 6 to move to the detection device 4 in sequence. When conducting on-site detection, it is only necessary to place the sample box 6 at a designated position, and then the electronic control operation can be performed for detection. During specific operation, the reference box 5 is first moved to the detection device 4 through the moving assembly, and then the sample box 6 is moved to the detection device 4. The detection device 4 compares the oil samples in the reference box 5 with those in the sample box 6, thereby determining the iron content in the oil sample to be detected, thereby improving the convenience of detection, and improving detection efficiency and accuracy. In addition, as an alternative implementation, the order in which the reference box 5 and the sample box 6 are moved to the detection device 4 is not particular, as long as they are moved to the detection device 4 in sequence so that the detection device 4 can compare the two.

[0044] In the ferromagnetic wear debris analysis detection mechanism provided in this embodiment, the moving component drives the reference box 5 and the sample box 6 to move by horizontal rotation, so that the reference box 5 and the sample box 6 are moved to the detection device 4 in sequence. In addition, as an alternative embodiment, the moving component can also drive the reference box 5 and the sample box 6 to move horizontally, so that the reference box 5 and the sample box 6 are moved to the detection device 4 in sequence.

[0045] like Figure 1 , Figure 2As shown, in the ferromagnetic wear debris analysis and detection mechanism provided in this embodiment, the moving assembly includes: a tray 1, a base plate 2 and a driving device 3, the tray 1 and the base plate 2 are arranged in parallel, the driving device 3 is fixed on the base plate 2, the driving shaft of the driving device 3 is connected to the tray 1, and the tray 1 is horizontally rotated relative to the base plate 2 by the driving of the driving device 3; specifically, the driving device 3 can be a stepping motor, the stepping motor is connected to the tray 1 by gear meshing transmission, the tray 1 has a transmission shaft 11 passing through the base plate 2, the transmission shaft 11 is connected to a transmission gear 10, the driving shaft of the stepping motor is sleeved with a driving gear, the driving gear is meshed with the transmission gear 10, so that when the driving shaft of the stepping motor rotates, the tray 1 can be driven to rotate. Among them, the detection device 4 is arranged on the base plate 2, the reference box 5 and the sample box 6 are respectively arranged on the tray 1, when the tray 1 rotates, the reference box 5 and the sample box 6 are suitable for being opposite to the detection device 4 in sequence. During detection, the reference box 5 and the sample box 6 are driven to move to the detection device 4 in sequence by horizontal rotation, which can reduce the space occupied by the mechanism and make the equipment miniaturized.

[0046] like Figure 2 As shown, the ferromagnetic wear debris analysis detection mechanism provided in this embodiment also includes: a standard sample block 12, the standard sample block 12 has two blocks with different concentrations, and the standard sample block 12 is used to standardize the detection range of the detection device 4, and the standard sample block 12 can be connected to the installation position of the sample box 6. In addition, as an alternative embodiment, the standard sample block 12 can also be set on other paths of the detection device 4 of the tray 1.

[0047] like Figure 3 As shown, in the ferromagnetic wear debris analysis detection mechanism provided by this embodiment, the positions for setting the reference box 5 and the sample box 6 on the tray 1 are set at a certain angle, and the tray 1 is also provided with a detection position 8 for cooperating with the photoelectric sensor 7, and the detection position 8 is set at 180° with the position of the sample box 6. Specifically, the detection position 8 is a notch. The photoelectric sensor 7 is connected to the bottom plate 2, and the 180° position on the bottom plate 2 opposite to the photoelectric sensor 7 is used to connect the detection device 4. In this way, when the photoelectric sensor 7 is opposite to the detection position 8, the detection device 4 is just opposite to the sample box 6, and when the tray 1 is rotated at a certain angle, the detection device 4 can be opposite to the reference box 5. In addition, as an alternative embodiment, the photoelectric sensor 7 can also adopt other conventional position detection devices, and the position detection device is electrically connected to the drive device 3, and the drive device 3 is driven according to the signal received from the position detection device.

[0048] like Figure 4-6 As shown, in the ferromagnetic wear debris analysis and detection mechanism provided in this embodiment, there is a gap between the upper surface of the bottom plate 2 and the lower surface of the tray 1. Specifically, there is an annular support bar 9 on the lower surface of the tray 1 protruding toward the upper surface of the bottom plate 2. The annular support bar 9 can make the bottom plate 2 and the tray 1 fit closely and rotate smoothly.

[0049] The ferromagnetic wear debris analysis and detection mechanism provided in this embodiment performs ferromagnetic wear debris analysis and detection, and its detection method is as follows: Figure 7 As shown, the following steps are included from left to right:

[0050] First, before the tray 1 is rotated, the detection device 4 can be calibrated by using two standard blocks 12 with different concentrations (for example, 0PQ and 750PQ) to calibrate the detection range of the detection device 4 .

[0051] Then, the sample box 6 is installed on the tray 1 , and the tray is rotated 120° by the moving assembly to move the sample box 6 to the detection device 4 , so that the detection device 4 detects the oil sample in the sample box 6 .

[0052] Then, the tray is further rotated 120° by the moving assembly to remove the sample box 6 , and the reference box 5 is moved to the detection device 4 at the same time, so that the detection device 4 detects the oil sample in the reference box 5 .

[0053] Finally, the tray 1 is rotated back to its original position by further rotating the tray 120° through the moving assembly, and the detection device 4 compares and analyzes the oil samples in the reference box 5 and the sample box 6 to output the content of ferromagnetic wear debris in the oil sample in the sample box 6 .

[0054] In this embodiment, the detection device 4 can be a detection probe of a conventional iron meter, and the electrical signal of the detection probe can be led to the controller through the wire, and the ferromagnetic wear debris content in the oil sample is analyzed by the controller. In addition, as an alternative embodiment, the order in which the reference box 5 and the sample box 6 are moved to the position of the monitoring device in sequence is not limited, that is, the detection device 4 can detect the reference box 5 first, or can detect the sample box 6 first.

[0055] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the present invention.
