Description

Technical Field

[0001] This utility model relates to the technical field of industrial non-destructive testing, and in particular to a device for simulating damage signal detection. Background Technology

[0002] The production of magnetic flux leakage (MF) equipment involves multiple stages, including design, material selection, production, testing, and quality control. First, technical design is conducted based on application requirements, selecting suitable magnetic materials and sensor components. Then, the electromagnetic coils, sensors, and circuit boards are precisely assembled to ensure the equipment can effectively detect changes in the magnetic field. After assembly, testing and debugging are performed to verify the equipment's detection accuracy and stability. Finally, rigorous quality control ensures the equipment is qualified and ready for use, with widespread applications in safety monitoring and detection in industries such as power, steel, machinery, and transportation.

[0003] The simulated damage signal detection device monitors the health status of equipment by simulating damage signals of structures or equipment and combining sensor technology. The device simulates damage by artificially creating defects or applying loads, and uses strain gauges, accelerometers, ultrasonic sensors, etc. to capture abnormal signals when the equipment is injured. These signals are amplified, filtered, and analyzed by the processing module to help diagnose potential structural problems and to trigger alarms or safety measures when an anomaly is detected. This device is widely used in aviation, bridges, machinery and equipment and other fields, and can effectively prevent accidents.

[0004] In existing technologies, because the spacing between detection blocks cannot be flexibly adjusted according to actual conditions, it may lead to the inability to accurately detect tiny cracks or damage inside the pipe. A fixed spacing between detection blocks may not be suitable for different pipe diameters or surface conditions, affecting the sensitivity and reliability of the detection. When there is corrosion or other physical damage on the pipe surface, the detection blocks with a fixed spacing may not be able to fully cover all possible damaged areas, thereby reducing the detection capability and accuracy of the system. Utility Model Content

[0005] In view of the problem that the fixed spacing of existing detection blocks leads to a reduction in detection capability and accuracy, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a simulated injury signal detection device, which aims to improve the sensitivity and accuracy of the signal by adjusting the distance between two electromagnetic detection blocks through a rotating rod driving a distance adjustment component.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a simulated injury signal detection device, including a base, a height adjustment component inside the base, casters installed at the four corners of the bottom of the base, a housing fixed at the top of the base, a spacing adjustment component inside the housing, an electromagnetic detection block installed above the spacing adjustment component, and a rotating rod for driving the spacing adjustment component on one side of the housing. The spacing adjustment assembly includes a bidirectional lead screw, which is rotatably connected inside the housing.

A worm gear body is fixed to one end of the bidirectional lead screw. A worm gear body that meshes with the worm gear body is located below the worm gear body. One end of the worm gear body extends to the outer wall of the housing and is fixedly connected to the rotating rod.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0019] Reference Figures 1-2 This is the first embodiment of the present invention, which provides a simulated injury signal detection device. The simulated injury signal detection device includes a base 1, a height adjustment component 2 is provided inside the base 1, universal wheels 3 are installed at the four corners of the bottom end of the base 1, a housing 4 is fixed at the top end of the base 1, a spacing adjustment component 5 is provided inside the housing 4, an electromagnetic detection block 7 is installed above the spacing adjustment component 5, and a rotating rod 6 for driving the spacing adjustment component 5 is provided on one side of the housing 4. The base is equipped with a height adjustment component, which, combined with the design of the universal wheels at the bottom, allows the overall height of the equipment to be adjusted while making it easy to move, thus enhancing the adaptability and portability of the testing device.

[0020] The spacing adjustment assembly 5 includes a bidirectional lead screw 501, which is rotatably connected inside the housing 4. Two square blocks 502 are symmetrically arranged on the surface of the bidirectional lead screw 501 and threadedly connected thereto. Two connecting rods 503 are symmetrically fixed at the top of the square blocks 502. The top of the connecting rods 503 is fixedly connected to the electromagnetic detection block 7. A worm gear body 504 is fixed at one end of the bidirectional lead screw 501. A worm gear body 505 meshes with the worm gear body 504 below it. One end of the worm gear body 505 extends to the outer wall of the housing 4 and is fixedly connected to the rotating rod 6. The spacing of the electromagnetic detection blocks can be adjusted by driving the symmetrical square blocks to move through a bidirectional lead screw, meeting the detection requirements of different sizes and improving the detection flexibility and applicability. The worm gear transmission has a self-locking characteristic, which can accurately control the adjustment process and maintain the stability after adjustment.

[0021] A square groove 401 is provided on the inner wall of the housing 4 at the corresponding position of the square block 502. The cross-sectional shape of the square block 502 is the same as that of the square groove 401. The square block 502 is slidably connected to the inner side of the square groove 401. The square block is slidably connected to the square groove inside the housing, which restricts the rotational freedom of the square block and ensures that it can only move linearly. This avoids the positional displacement of the electromagnetic detection block caused by the rotation of the bidirectional lead screw and improves the adjustment accuracy.

[0022] A groove 402 is provided above the square groove 401. The inner wall of the groove 402 is in contact with the surface of the connecting rod 503, and the connecting rod 503 is slidably connected to the inner side of the groove 402. The connecting rod slides within the groove, further restricting the displacement path of the electromagnetic detection block, preventing shaking caused by vibration or external force during the detection process, and ensuring the stability of the detection signal. Example 2

[0023] Reference Figures 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the height adjustment component 2 includes a drive motor 201, which is fixed inside the base 1. The output end of the drive motor 201 is fixed to a first transmission wheel 202 via a coupling. The surface of the first transmission wheel 202 is provided with two first transmission chains 203 that are rotatably connected to it at equal distances. A second transmission wheel 204 is sleeved on the inner side of one end of the first transmission chain 203. A second transmission chain 205 is rotatably connected to the side of the second transmission wheel 204. A third transmission wheel 206 is sleeved on the inner side of one end of the second transmission chain 205. A threaded rod 207 is fixed to the top of the second transmission wheel 204 and the third transmission wheel 206. A column 208 is threadedly connected to the surface of the threaded rod 207. A T-shaped rod 209 is fixed to the bottom of the second transmission wheel 204 and the third transmission wheel 206. The system employs a drive motor in conjunction with a multi-stage transmission chain and transmission wheels to synchronously drive the rotation of multiple threaded rods, ensuring the synchronicity and stability of the housing's lifting and lowering. The diameter of the first transmission wheel is twice that of the second transmission wheel, and the torque is increased through the reduction ratio, thereby enhancing the load capacity of the lifting mechanism.

[0024] A groove 101 is provided at the top of the base 1 at the position corresponding to the column 208. The surface of the column 208 is in contact with the inner side of the groove 101, and the column 208 is slidably connected to the inner side of the groove 101. The column slides within the groove, restricting its movement to vertical only. This prevents the column from deflecting when the threaded rod rotates, ensuring the stability of the housing's vertical lifting and lowering.

[0025] A limiting groove 102 is provided on the inner bottom wall of the base 1 at the position corresponding to the T-shaped rod 209. The inner shape of the limiting groove 102 is the same as the shape of the T-shaped rod 209. The T-shaped rod 209 is rotatably connected to the inner side of the limiting groove 102. The T-shaped rod 209 limits the second transmission wheel 204 and the third transmission wheel 206 through the limiting groove 102. The T-shaped rod rotates within the limiting groove, using the T-shaped structure to limit the radial displacement of the transmission wheel, preventing the transmission wheel from shifting or vibrating under force, and ensuring the meshing reliability of the transmission chain; the shape of the limiting groove matches the T-shaped rod, further enhancing the fixing effect on the position of the transmission wheel.

[0026] The diameter of the first transmission wheel 202 is twice the diameter of the second transmission wheel 204, and the diameter of the second transmission wheel 204 is the same as the diameter of the third transmission wheel 206.

[0027] The remaining structure is the same as that in Example 1.

[0028] Based on embodiments 1-2, the working principle of this utility model is as follows: The user can detect the device through the electromagnetic detection block 7. The rotating rod 6 can drive the spacing adjustment component 5 inside the housing 4 to adjust the spacing of the electromagnetic detection block 7. The height adjustment component 2 inside the base 1 can adjust the height of the housing 4, thereby adjusting the detection height of the electromagnetic detection block 7. The universal wheels 3 at the bottom of the base 1 make it easy for the user to move the entire device. Rotating the rotating rod 6 drives the worm body 505 to rotate, which in turn drives the worm wheel body 504 to rotate. The worm wheel body 504 synchronously drives the bidirectional lead screw 501 to rotate. Because the bidirectional lead screw 501 and the square block 502 are connected by threads, the square block 502 moves linearly inside the square groove 401. The two square blocks 502 move relative to each other or repel each other. The square block 502 drives the electromagnetic detection block 7 to adjust the spacing through the connecting rod 503. The connecting rod 503 slides inside the groove 402 to prevent the electromagnetic detection block 7 from shifting position. The height of the housing 4 can be adjusted by the height adjustment component 2. The first transmission wheel 202 is driven to rotate by the drive motor 201. The first transmission wheel 202 drives the second transmission wheel 204 to rotate via the first transmission chain 203. The second transmission wheel 204 drives the third transmission wheel 206 to rotate via the second transmission chain 205, so that the first transmission wheel 202, the second transmission wheel 204 and the third transmission wheel 206 rotate synchronously. The second transmission wheel 204 and the third transmission wheel 206 drive the corresponding threaded rod 207 to rotate. The threaded rod 207 is threadedly connected to the column 208, so that the column 208 slides inside the slide groove 101, thereby driving the housing 4 to move up and down. The T-shaped rod 209 corresponding to the bottom of the second transmission wheel 204 and the third transmission wheel 206 rotates inside the limiting groove 102. Due to the shape characteristics of the T-shaped rod 209, the positional deviation of the corresponding second transmission wheel 204 and the third transmission wheel 206 is effectively prevented.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
