Description

Technical Field

[0001] This utility model relates to the field of electromagnetic feature detection technology, specifically to an electromagnetic feature detection device based on a magnet coil. Background Technology

[0002] A Maxwell coil is a device that can generate a uniform magnetic field or a uniform gradient magnetic field under large volume conditions. Electromagnetic characteristic detection is performed using Maxwell coils, mainly based on Maxwell's law of electromagnetic induction. A changing magnetic field induces an electric field, and a changing electric field generates a magnetic field. By observing the voltage waveform of the secondary coil through an oscilloscope, the frequency and intensity of the magnetic field and the conductivity differences of the tested object, such as metal defects or biological tissue, can be analyzed.

[0003] The electromagnetic feature detection of objects requires the use of Maxwell coil detection equipment. Traditional Maxwell coil detection equipment cannot fix the object being detected. During detection, the object being detected is very easy to shift its position due to external forces, causing it to deviate from the center of the magnetic field, thus leading to deviations in the detection results.

[0004] Therefore, the Maxwell coil detection equipment needs to be redesigned and modified to enable it to fix the object being detected. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5 As shown, the present invention provides an electromagnetic feature detection device based on a magnet coil, including a control base 1, a Maxwell coil 2 connected to the top of the control base 1, an L-shaped box 3 fixedly connected to the middle of the top of the control base 1, a placement box 4 fixedly connected to the top of the L-shaped box 3, a turntable 5 movably connected to the bottom of the inner wall of the placement box 4 via a bearing, a slide groove 6 opened on the top of the turntable 5, the number of slide grooves 6 is four, a slider 7 slidably connected to the inner wall of the slide groove 6, a connecting block 8 fixedly connected to the top of the slider 7, a limit rod 9 slidably connected to the inner wall of the connecting block 8, both ends of the limit rod 9 being fixedly connected to the inner wall of the placement box 4, and a clamping block 10 fixedly connected to the top of the connecting block 8 extending through to the top of the placement box 4.

[0025] A vertical rod 11 is fixedly connected to the bottom of the turntable 5. The bottom of the vertical rod 11 passes through the placement box 4 and extends into the interior of the L-shaped box 3. A helical gear 12 is fixedly connected to the surface of the vertical rod 11. A helical gear 13 meshes with the front side of the helical gear 12. A horizontal rod 14 is fixedly connected to the front side of the helical gear 13. The front side of the horizontal rod 14 is movably connected to the front side of the inner wall of the L-shaped box 3 through a bearing. The front side of the horizontal rod 14 passes through to the front side of the L-shaped box 3 and is fixedly connected to a rotating block 15. Except for the control base 1 and the Maxwell coil 2, the materials used in this fixing structure are all plastic.

[0026] refer to Figure 4 and Figure 5 A rotating block 17 is movably connected to the front side of the L-shaped box 3 and the bottom of the rotating block 15 via a bearing. The rear side of the rotating block 17 extends through to the front side of the inner wall of the L-shaped box 3 and is fixedly connected to a screw 18. A rectangular screw sleeve 19 is threaded onto the surface of the screw 18. A brake pad 20 is fixedly connected to the rear side of the rectangular screw sleeve 19. A brake block 16 that mates with the brake pad 20 is fixedly connected to the bottom of the vertical rod 11.

[0027] As a technical optimization of this utility model, by setting a rotating block 17, a screw 18, a rectangular screw sleeve 19, a brake pad 20 and a brake block 16, the vertical rod 11 can be fixed to prevent the vertical rod 11 from rotating during testing.

[0028] refer to Figure 5 The rectangular threaded sleeve 19 has limit grooves 21 on both the left and right sides. The inner wall of the limit groove 21 is slidably connected to the limit block 22, and the outer side of the limit block 22 is fixedly connected to the inner wall of the L-shaped box 3.

[0029] As a technical optimization of this utility model, by setting the limiting groove 21 and the limiting block 22, the range of motion of the rectangular threaded sleeve 19 can be limited, preventing the rectangular threaded sleeve 19 from tilting during use.

[0030] refer to Figure 3 The surfaces of rotating block 15 and rotating block 27 are both provided with anti-slip texture 23, which is rhomboid in shape.

[0031] As a technical optimization of this utility model, by setting anti-slip texture 23, the friction between the user's hands and rotating block 15 and rotating block 27 can be increased, preventing rotating block 15 and rotating block 27 from slipping out of the hand during use.

[0032] refer to Figure 1 The bottom of the control base 1 is fixedly connected with anti-slip blocks 24, and there are four anti-slip blocks 24.

[0033] As a technical optimization of this utility model, by setting the anti-slip block 24, the friction between the control base 1 and the plane can be increased, preventing the control base 1 from slipping during use.

[0034] refer to Figure 4 Support plates 25 are fixedly connected to the bottom of the box 4 at the rear, left and right positions. The support plates 25 are triangular in shape.

[0035] As a technical optimization of this utility model, by setting a support plate 25, the placement box 4 can be supported to prevent the placement box 4 from tilting during use.

[0036] refer to Figure 4 A fixing plate 26 is movably connected to the surface of the crossbar 14 via a bearing. The top of the fixing plate 26 is fixedly connected to the bottom of the placement box 4 at the front position.

[0037] As a technical optimization of this utility model, by setting the fixing plate 26, the crossbar 14 can be limited and fixed to prevent the crossbar 14 from tilting during use.

[0038] The working principle and usage process of this utility model are as follows: First, place the object to be tested on top of the placement box 4. Then, rotate the rotating block 15. The rotating block 15 drives the horizontal bar 14 to rotate, which in turn drives the helical gear 13 to rotate. The helical gear 13 drives the helical gear 12 to rotate, which in turn drives the vertical bar 11 to rotate. The vertical bar 11 then drives the turntable 5 to rotate. Using the sliding groove 6, the turntable 5 drives the slider 7 to move inward. The slider 7 drives the connecting block 8 to move inward, which in turn drives the clamping block 10 to move inward, bringing the clamping block 10 into contact with the object to be tested. At this point, the object can be fixed. After fixing, rotate the rotating block 17. The rotating block 17 drives the screw 18 to rotate, which in turn drives the screw 18 to move the rectangular screw sleeve 19 backward. The rectangular screw sleeve 19 drives the brake pad 20 to move backward, bringing the brake pad 20 into contact with the brake block 16. At this point, the position of the clamping block 10 is fixed, thus achieving the effect of a fixed structure.

[0039] In summary, this electromagnetic feature detection device based on a magnet coil, by setting up a control base 1, a Maxwell coil 2, an L-shaped box 3, a placement box 4, a turntable 5, a slide 6, a slider 7, a connecting block 8, a limiting rod 9, a clamping block 10, a vertical rod 11, a helical gear one 12, a helical gear two 13, a horizontal rod 14, and a rotating block one 15, solves the problem that traditional Maxwell coil detection equipment cannot fix the object being detected. During detection, the object being detected is very easy to shift its position due to external forces, causing it to deviate from the center of the magnetic field and thus resulting in deviations in the detection results.
