[0019] Compared with the prior art, the present invention provides an integrated sensor for magnetic field measurement and a system thereof, which has the following beneficial effects:

[0020] 1. The integrated sensor for magnetic field measurement is mostly provided with a plurality of heat sinks on the outer shell surface of the motor. The ends of the two T-shaped columns away from the rotating disk can be respectively clamped on the surfaces of the two heat sinks. The reaction force generated by the deformation of the first spring sheet and the second spring sheet can be stably clamped with the heat sinks on the surface of the motor shell. The two T-shaped columns can be adjusted to rotate by adjusting the movement of the two adjustment plates at the same time. The two T-shaped columns can be installed at the specified position of the motor shell according to actual needs. The two adjustment plates can be adjusted to rotate again to separate the T-shaped columns from the heat sinks on the surface of the motor shell, which is convenient for installation and disassembly between the substrate and the motor shell, and convenient for continuous operation in experimental teaching to avoid affecting the use of the substrate.

[0021] 2. The integrated sensor for measuring magnetic field is respectively provided with a first bevel groove and a second bevel groove on the surface of the rotating disk and the surface of the back cover. The T-shaped column can contact the surfaces of the first bevel groove and the second bevel groove during the rotation adjustment process. There is a negative angle between the T-shaped column and the rotating disk. By utilizing the elastic force of the first spring sheet and the second spring sheet, the arc groove on the surface of the T-shaped column can be in close contact with the annular extension surface of the motor housing surface, so that the substrate is installed on the surface of the motor housing on the inner side of the annular extension, thereby increasing the installation range of the substrate on the surface of the motor housing.

[0022] 3. The integrated sensor for magnetic field measurement, in the process of adjusting the rotation of the two T-shaped columns, the U-shaped column and the wiping cloth can move with the adjustment plate to clean the surface of the substrate, which can shorten the time required for substrate maintenance and improve maintenance efficiency. After the T-shaped column and the heat sink are installed in coordination, the two adjustment plates are continued to be adjusted to move in the direction of approaching each other, the connecting sleeve moves with the adjustment plate, and then the connecting sleeve contacts the surface of the fixed ring, driving the first connecting column to move together, and relative sliding occurs between the first trapezoidal block and the second trapezoidal block. The movable column moves with the second trapezoidal block, and the first adjustment block cooperates with the second adjustment block to drive the second adjustment block to move. The cleaning brush passes through multiple through holes, and only the adjustment plate and the substrate need to be adjusted to move back and forth to clean the gaps between the multiple heat sinks on the surface of the motor housing, thereby increasing the versatility of the body itself, and cleaning the gaps between the heat sinks can remove impurities such as dust and dirt, reduce interference with magnetic field measurement, and ensure that the sensor can accurately obtain magnetic field data.

Through holes are equidistantly provided at one end of the groove wall of the installation groove 33 away from the first trapezoidal block 34;

[0040] It should be noted that in the process of adjusting the rotation of the two T-shaped columns 31, the U-shaped column 422 and the wiping cloth can move together with the adjustment plate 414 to clean the surface of the base 1, which can shorten the time required for maintenance of the base 1 and improve maintenance efficiency. After the T-shaped column 31 is installed in coordination with the heat sink, the two adjustment plates 414 are continued to be adjusted to move in a direction close to each other, and the connecting sleeve 37 moves together with the adjustment plate 414, and then the connecting sleeve 37 contacts with the surface of the fixed ring, driving the first connecting column 36 to move together, and relative sliding occurs between the first trapezoidal block 34 and the second trapezoidal block 35. The movable column 311 moves together with the second trapezoidal block 35, and the first adjustment block 312 cooperates with the second adjustment block 313 to drive the second adjustment block 313 to move. The cleaning brush 314 passes through multiple through holes, and the gaps between the multiple heat sinks on the surface of the motor housing can be cleaned by adjusting the adjustment plate 414 and the base 1 to move back and forth.

[0043] See also Figure 1 , Figure 3 , Figure 5 and Figure 8 The adjusting component 41 includes a protrusion 411 symmetrically fixedly connected to the inner wall of the rotating sleeve 2, and adjusting columns 412 are installed at both ends of the inner wall of the rotating sleeve 2. The surface of the adjusting column 412 is provided with a spiral groove 413, and the protrusion 411 is installed in cooperation with the spiral groove 413.

When the two adjustment plates 414 move toward each other, the adjustment column 412 moves with the adjustment plate 414, and relative movement occurs between the protrusion 411 and the spiral groove 413, thereby driving the rotating sleeve 2 to rotate, and the first elastic sheet 32 ​​is deformed, thereby driving the T-shaped column 31 to rotate, and adjusting the two T-shaped columns 31 to cooperate with the heat sink on the surface of the motor housing, and then loosening the two adjustment plates 414 at the same time. Under the elastic force of the first elastic sheet 32 ​​and the second elastic sheet 416, the T-shaped column 31 can be stably matched with the motor housing to complete the installation. Adjusting the two adjustment plates 414 to rotate again can separate the T-shaped column 31 from the heat sink on the surface of the motor housing, which is convenient for installation and disassembly between the base 1 and the motor housing, and convenient for continuous operation in experimental teaching.

[0045] See also Figure 1 , Figure 3 , Figure 6 and Figure 8 The cleaning assembly 42 includes an L-shaped column 421 fixedly connected to the surface of the adjustment plate 414 and located next to the horizontal column 415.

[0049] It should be noted that, during the rotation adjustment process, the T-shaped column 31 can contact the surfaces of both the first bevel groove and the second bevel groove, and a negative angle is present between the T-shaped column 31 and the rotating disk 12. By utilizing the elastic force of the first spring piece 32 and the second spring piece 416, the arc groove on the surface of the T-shaped column 31 can be in close contact with the annular extension surface of the motor housing surface, so that the base 1 is installed on the surface of the motor housing on the inner side of the annular extension, thereby increasing the installation range of the base 1 on the surface of the motor housing.

[0050] See also Figure 3 The end of the surface of the T-shaped column 31 away from the rotating disk 12 is symmetrically provided with an arc groove;

[0051] It should be noted that the arc groove can contact the annular extended surface of the motor housing surface to provide support for the installation of the base 1. Rubber pads can be provided on the surface of the arc groove and the T-shaped column 31 away from the rotating disk 12. The rubber pads can provide vibration buffering for the base 1. The friction force generated by the contact between the rubber pads and the surface of the motor housing can ensure the stable installation of the base 1.
