Description

Technical Field

[0001] The present invention relates to the technical field of magnetic force test and detection, and specifically to a damping oscillating magnetic field test device with adjustable intensity. Background Technique

[0002] A damping oscillating magnetic field test device with adjustable intensity usually consists of parts such as a damping oscillating magnetic field interference generator, a magnetic field sensor, a temperature control device, and a protection device.

[0003] The patent with the patent announcement number CN109100594B relates to a damping oscillating magnetic field test device with adjustable intensity, including a damping oscillating magnetic field interference generator and a current-carrying coil. The damping oscillating magnetic field interference generator outputs a current signal to the current-carrying coil, and the current-carrying coil generates a magnetic field with adjustable intensity. The protection device to be tested is placed in the magnetic field generated by the current-carrying coil. When conducting the test, the magnetic field intensity is adjusted, such as increasing the magnetic field intensity to an appropriate level or until the protection of the protection device to be tested fails, to test the ability of the protection device to be tested to withstand magnetic field interference, so as to find the weak point of the protection device to be tested in withstanding magnetic field interference. Therefore, this test device generates a variable interference magnetic field intensity and can also increase the damping oscillating magnetic field intensity to several times that of a standard generator, more realistically simulating the actual working environment, making the anti-interference performance result of the protection device against a strong magnetic field more real and accurate, and solving the problem that the test results in the prior art do not match the actual situation.

[0014] The present invention provides a damped oscillating magnetic field test device with adjustable intensity. It has the following beneficial effects:

[0015] (1) For this damped oscillating magnetic field test device with adjustable intensity, when the protection plate moves backward to contact the top of the L-shaped plate and limit the L-shaped plate, the accidental opening of the test frame may lead to the instability of the test environment.

[0016] (2) For the test device of the adjustable-intensity damped oscillating magnetic field, when the support plate moves downward to contact the inner wall of the support hole, the fastening effect of the hollow rod on the magnetic sample can be improved. The hollow rod can fasten the magnetic sample in the test frame through its physical structure, ensuring that the magnetic sample does not displace during the magnetic field change, thus making the test results more accurate. By moving the Z-shaped plate downward to contact the top of the sample and assist in fixing the top of the sample, the uniform action of the magnetic field on the sample can be further ensured, thereby improving the accuracy of the measurement test.

[0017] (3) For the test device of the adjustable-intensity damped oscillating magnetic field, when the protection plate moves forward to drive the moving plate forward, the moving plate moves forward to block the adjustment button. The adjustment button being blocked by the moving plate makes it impossible to adjust the intensity of the damped oscillating magnetic field generator during the test. By being unable to adjust the magnetic field intensity during the test, the possibility of improper adjustment of the magnetic field intensity by the operator can be eliminated, thereby avoiding drastic changes in the test conditions due to adjustment errors, and ensuring the coherence and reliability of the test process.

Specific implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 - 6 , an embodiment of the present invention is: a damping oscillating magnetic field test device with adjustable intensity, including a test frame 1, and further including a protection device. Among them, a damping oscillating magnetic field interference generator 2 is arranged on the front side of the test frame 1, a magnetic field sensor 3 is arranged on the left side of the test frame 1, and a temperature control device 4 is arranged on the right side of the damping oscillating magnetic field interference generator 2. Among them, the protection device includes a test hole 5, a shielding rod 6, an L-shaped plate 7, a separation plate 8, a hollow frame 9, a T-shaped rod 10 and a protection plate 11. The test hole 5 is opened on the right side of the test frame 1, the shielding rod 6 is fixedly installed on the top of the test frame 1, the L-shaped plate 7 is slidably installed on the circumferential surface of the shielding rod 6, the separation plate 8 is fixedly installed on the inner wall of the temperature control device 4, the hollow frame 9 is fixedly installed on the top of the test frame 1, the T-shaped rod 10 is slidably installed on the inner wall of the hollow frame 9, and the protection plate 11 is fixedly installed on the front side of the T-shaped rod 10. A first spring is arranged between the test frame 1 and the L-shaped plate 7. By limiting the L-shaped plate 7 through the protection plate 11, the test frame 1 during the test can be prevented from being opened, the test conditions can be kept stable, and the reliability and accuracy of the test detection data can be ensured.

[0029] A linkage rack 12 is provided at the bottom of the protective plate 11. A rotating rod 13 passes through the left and right walls of the separation plate 8 in a rotating manner. A linkage gear 14 is fixedly installed on the circumferential surface of the rotating rod 13. A pushing plate 15 is fixedly installed on the circumferential surface of the rotating rod 13. An arc-shaped plate 16 is fixedly installed on the right side of the separation plate 8. By improving the temperature control effect of the temperature control device 4, the temperature of the damping oscillation magnetic field interference generator 2 can be kept stable during the test, thereby optimizing the working environment of the damping oscillation magnetic field interference generator 2.

[0030] The arc-shaped plate 16 has elasticity. The linkage rack 12 is engaged with the linkage gear 14. A second spring is provided between the hollow frame 9 and the T-shaped rod 10. The second spring can drive the T-shaped rod 10 to reset. The protective plate 11 contacts the L-shaped plate 7. A U-shaped frame 186 is fixedly installed at the bottom of the damping oscillation magnetic field interference generator 2. An adjustment button 188 is fixedly installed inside the U-shaped frame 186. The intensity of the damping oscillation magnetic field interference generator 2 can be adjusted through the adjustment button 188. The adjustment button 188 is electrically connected to the damping oscillation magnetic field interference generator 2.

[0031] During the operation of this embodiment: The magnetic sample is placed into the interior of the test frame 1 through the test hole 5. After the sample is stably placed inside the test frame 1, manually push the L-shaped plate 7 downward. When the L-shaped plate 7 moves downward, it squeezes the first spring. The first spring deforms and stores energy under the extrusion of the L-shaped plate 7. At the same time, as the L-shaped plate 7 moves downward, it disengages from the contact with the protective plate 11. When the protective plate 11 disengages from the contact with the L-shaped plate 7, the T-shaped rod 10 moves backward under the elastic force of the second spring. The backward movement of the T-shaped rod 10 drives the protective plate 11 to move backward. The backward movement of the protective plate 11 contacts the top of the L-shaped plate 7 and limits the L-shaped plate 7. At the same time, the backward movement of the protective plate 11 drives the linkage rack 12 to move. The movement of the linkage rack 12 squeezes the linkage gear 14 to rotate. The rotation of the linkage gear 14 drives the push plate 15 to rotate. The rotation of the push plate 15 pushes the foreign matter on the right side of the separation plate 8. At the same time, the rotation of the push plate 15 impacts the arc-shaped panel 16 to generate vibration. The vibration generated by the arc-shaped panel 16 drives the separation plate 8 to resonate together, thereby improving the temperature control effect of the temperature control device 4. After the L-shaped plate 7 completely covers the test hole 5 during its downward movement, start the damped oscillation magnetic field interference generator 2 and the magnetic field sensor 3 to conduct tests on the magnetic sample. By adjusting the adjustment button 188, the damped oscillation magnetic field interference generator 2 can be adjusted to regulate the magnetic force intensity generated by the damped oscillation magnetic field interference generator 2. After the test is completed, manually pull the protective plate 11 forward. The forward movement of the protective plate 11 drives the T-shaped rod 10 to move forward. The forward movement of the T-shaped rod 10 pulls the second spring. The second spring deforms and stores energy under the pull of the T-shaped rod 10. At the same time, the forward movement of the protective plate 11 disengages from the contact with the top of the L-shaped plate 7 and releases the limit on the L-shaped plate 7. After the limit on the L-shaped plate 7 is released, the L-shaped plate 7 moves upward and resets under the elastic force of the first spring. The upward movement and reset of the L-shaped plate 7 release the occlusion of the test hole 5. After the occlusion of the test hole 5 is released, manually take out the sample inside the test frame 1.

[0032] Please refer to Figures 1 - 8, on the basis of the above embodiments, in another embodiment of the present invention, a fastening device for preventing the test article from shifting is provided on the inner wall of the test frame 1, and a protection device is provided on the front side of the test frame 1.

The hollow rod 174 can fasten the magnetic sample in the test frame 1 through a physical structure, so as to ensure that the magnetic sample does not displace during the magnetic field change process, thereby making the test results more accurate.

[0033] A Z-shaped plate 179 is slidably installed on the inner wall of the hollow rod 174. The Z-shaped plate 179 contacts the support plate 178. The right side of the hollow rod 174 is set as an inclined surface. The hollow rod 174 penetrates the inner and outer walls of the test frame 1. The Z-shaped plate 179 moves downward to contact the top of the sample and assist in fixing the top of the sample. By assisting in fixing the top of the magnetic sample, it can further ensure that the action of the magnetic field on the sample is uniform, thereby assisting in improving the accuracy of the measurement test.

[0034] A third spring is provided between the connection plate 175 and the hollow rod 174. The third spring can drive the connection plate 175 to reset. A fourth spring is provided between the support plate 178 and the placement hole 176. The fourth spring can drive the support plate 178 to reset. The top of the support plate 178 is set as an inclined surface.

[0035] The protection device includes a detection frame 181, a connection frame 182, a protection frame 183, a protection plate 184, a linkage plate 185, and a moving plate 187. The detection frame 181 is fixedly installed on the top of the Z-shaped plate 179. The connection frame 182 is slidably installed on the inner wall of the detection frame 181. The protection frame 183 fixedly penetrates the front side of the test frame 1. The protection plate 184 is slidably installed on the inner wall of the protection frame 183. The linkage plate 185 is fixedly installed on the front side of the protection plate 184. The moving plate 187 is fixedly installed on the front side of the linkage plate 185. A hose is provided between the detection frame 181 and the protection frame 183. A moving hole is opened on the top of the moving plate 187. Since the magnetic field intensity cannot be adjusted during the test process, the possibility of improper adjustment of the magnetic field intensity by the operator can be eliminated, thereby avoiding drastic changes in the test conditions caused by adjustment errors, and ensuring the continuity and reliability of the test process.

[0036] A fifth spring is arranged between the detection frame 181 and the connection frame 182. The connection frame 182 can be driven to reset by the fifth spring. There is liquid inside the detection frame 181 and liquid inside the protection frame 183. The connection frame 182 penetrates through the upper and lower walls of the Z-shaped plate 179.

[0037] When this embodiment works: The L-shaped plate 7 moves downward to contact the inclined surface of the hollow rod 174 and extrude the hollow rod 174. The hollow rod 174 moves in the direction close to the magnetic field sensor 3 under the extrusion of the L-shaped plate 7. The movement of the hollow rod 174 in the direction close to the magnetic field sensor 3 drives the connection plate 175 to move. The connection plate 175 moves to contact the sample and extrude the sample. The connection plate 175 moves in the direction close to the L-shaped plate 7 under the reaction force of the extruded sample. The connection plate 175 moves in the direction close to the L-shaped plate 7 to extrude the third spring. The third spring deforms and stores energy under the extrusion of the connection plate 175. At the same time, the connection plate 175 moves in the direction close to the L-shaped plate 7 to contact the inclined surface of the support plate 178 and extrude the support plate 178. The support plate 178 moves downward under the extrusion of the connection plate 175. The support plate 178 moves downward to contact the inner wall of the support hole 1710 and support the hollow rod 174. At the same time, the hollow rod 174 extrudes and fastens the sample. When the support plate 178 moves downward under the extrusion of the connection plate 175, the support plate 178 drives the Z-shaped plate 179 to move downward when it moves downward. The Z-shaped plate 179 moves downward to contact the top of the sample and assist in fixing the top of the sample.

[0038] The downward movement of the Z-shaped plate 179 drives the detection frame 181 to move downward. The downward movement of the detection frame 181 drives the connection frame 182 to move downward. The connection frame 182 moves downward to contact the top of the sample and extrude the top of the sample. The connection frame 182 moves upward under the reaction force of the extruded sample. The connection frame 182 moves upward to extrude the fifth spring. The fifth spring deforms and stores energy under the extrusion of the connection frame 182. At the same time, the connection frame 182 moves upward to extrude the liquid inside the detection frame 181. The liquid inside the detection frame 181 enters the inside of the protection frame 183 through the hose under the extrusion of the connection frame 182. The liquid entering the inside of the protection frame 183 extrudes the protection plate 184. The protection plate 184 moves forward under the extrusion of the liquid entering the inside of the protection frame 183. The forward movement of the protection plate 184 drives the moving plate 187 to move forward. The forward movement of the moving plate 187 blocks the adjustment button 188. The adjustment button 188 is blocked by the moving plate 187, making it impossible to adjust the intensity of the damped oscillating magnetic field generator 2 during the test.
