[0004] When using existing magnetic field testing devices, the number of coils is mostly fixed, which makes it inconvenient to adjust the magnetic field strength of the magnetic field testing device and the number of coils to test the performance of magnetic materials under different magnetic field strengths, making it inconvenient to use. Summary of the invention

[0006] To achieve the above object, the present invention provides the following technical solution: a large-scale combined fast-adjustable combined magnetic field testing device that is easy to adjust, comprising a bracket, an end bracket is fixed on the top of the bracket, and iron bars are equidistantly installed on the ring side of the end bracket, wherein:

[0008] A cooling water pipe bracket is fixed on one side of the coil fixing block, and the iron rod is fixedly connected to the cooling water pipe bracket through a connecting flange.

[0009] Preferably, the bracket is integrally fixedly connected to the end frame.

[0010] Preferably, the coils are fixedly connected by iron rods.

[0011] Preferably, the iron rod connecting blocks are fixedly connected to the end frames and the connecting flanges by bolts, and the bolt torque is not greater than 12n / m.

[0012] Preferably, a cooling water pipe is installed on the cooling water pipe bracket, and the inner side of the cooling water pipe bracket is a curved surface.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, the coil is fixedly connected to the iron rod through a coil fixing block, and the iron rods are detachably connected through an iron rod connecting block. Single coil control is adopted, and the number of coils can be freely adjusted to measure the magnetic field strength of different numbers of coils, which is convenient for adjusting the number of coils and can achieve the purpose of uniform distribution of the central magnetic field strength.

[0015] 2. In the present invention, the iron rod connecting blocks and the end frames and connecting flanges are fixedly connected by bolts, and the bolt torque is not greater than 12n / m. When the number of coils needs to be adjusted, the bolts need to be installed and disassembled.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0022] Example:

[0023] See also Figures 1 to 3The present invention provides a technical solution: a large-scale combined fast-adjustable combined magnetic field test device that is easy to adjust, comprising a bracket 1, an end bracket 2 is fixed on the top of the bracket 1, and iron rods 3 are equidistantly installed on the ring side of the end bracket 2, wherein:

[0024] A coil 4 is installed inside the iron rod 3, and the coil 4 is installed inside the iron rod 3 through a coil fixing block 5. The iron rods 3 are slidably connected through an iron rod connecting block 6;

[0025] A cooling water pipe bracket 7 is fixed on one side of the coil fixing block 5 , and the iron rod 3 is fixedly connected thereto via a connecting flange 8 .

[0026] See also Figure 1 The bracket 1 is fixedly connected to the end frame 2 as a whole, the coils 4 are fixedly connected by the iron rod 3, the coils 4 are fixedly connected to the iron rod 3 by the coil fixing block 5, and the iron rods 3 are detachably connected by the iron rod connecting block 6. The single coil control is adopted, and the number of coils 4 can be freely adjusted to measure the magnetic field strength of different numbers of coils 4, which is convenient for adjusting the number of coils 4 and can achieve the purpose of uniform distribution of the central magnetic field strength;

[0027] See also Figure 1 and Figure 3 The iron rod connecting block 6 is fixedly connected with the end frame 2 and the connecting flange 8 by bolts, and the bolt torque is not more than 12n / m. When the number of coils 4 needs to be adjusted, the bolts need to be installed and removed. The bolts can be used to stably connect the components, and at the same time, the bolt torque is too large to cause the coils 4 to be unable to be removed, so that the coils 4 can be easily installed or removed. A cooling water pipe is installed on the cooling water pipe bracket 7, and the inner side of the cooling water pipe bracket 7 is a curved surface. The cooling water pipe is installed on the cooling water pipe bracket 7. When the coil 4 is energized and the magnetic field strength is tested, the cooling water flowing in the cooling water pipe dissipates the heat of the coil 4, which can effectively improve the heat dissipation efficiency of the magnetic field testing device and avoid the coil 4 from being overheated.

[0028] Working principle: This is a large-scale combined fast-adjustable combined magnetic field testing device that is easy to adjust. The coil 4 is fixedly connected to the iron rod 3 through the coil fixing block 5. The iron rods 3 are detachably connected through the iron rod connecting block 6. Single-coil control is adopted, and the number of coils 4 can be freely adjusted to measure the magnetic field strength of different numbers of coils 4, which is convenient for adjusting the number of coils 4 and can achieve the purpose of uniform distribution of the central magnetic field strength. When the number of coils 4 needs to be adjusted, the bolts need to be installed and disassembled. The bolts can be used to stably connect the components, and at the same time, it is avoided that the bolt torque is too large to be disassembled, which is convenient for installing or disassembling the coil 4. Before testing the magnetic field strength, the cooling water pipe is installed on the cooling water pipe bracket 7. When the coil 4 is energized and the magnetic field strength is tested, the cooling water flowing in the cooling water pipe dissipates the heat of the coil 4, which can effectively improve the heat dissipation efficiency of the magnetic field testing device and avoid the coil 4 from being overheated.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
