[0032] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be more thorough and complete.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0034] It is understood that spatial relation terms such as "below," "under," "below," "below," "above," "over," etc., can be used here to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, the element or feature described as "below" or "under" or "below" of other elements or features will be oriented "over" of other elements or features. Therefore, the exemplary terms "below" and "under" can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0035] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. In the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have the transmission of electrical signals or data between them.

[0036] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0037] like Figure 1 The diagram illustrates the principle of electromagnetic track velocimetry in the prior art. A drive coil (large Rogowski coil) is energized to generate a driving magnetic field, which drives the armature to slide along the length of the track. When the armature moves at a velocity v in the track, it generates a changing magnetic field around the track. Magnetic probe arrays S1~S2 are installed beside the track.n A small Rogowski coil senses changes in the magnetic field and generates an electromotive force (EMF) within its coil. A magnetic probe array converts these induced magnetic field changes into electrical signals, reflecting the rate of change of magnetic flux caused by armature motion. These electrical signals are acquired by a data acquisition unit and transmitted to an industrial control computer for processing and analysis. Based on the EMF signals output by the magnetic probe array, the industrial control computer calculates the armature's velocity using the correlation between the magnetic field and armature velocity. By measuring the time it takes for the armature to pass through different positions of magnetic probe 1, the average velocity of the armature in each segment can be calculated, and further fitting yields the armature's velocity-time curve.

[0038] Since the installation accuracy of the magnetic probe array is closely related to the velocity measurement accuracy, the existing magnetic probe installation and debugging process is complicated and difficult to adapt to different track types. Furthermore, the probes are fixedly installed on the track with fixed spacing, which makes it impossible to flexibly optimize the measurement effect and provide real-time feedback of the precise spacing to the software. This results in limited measurement accuracy, inconvenient operation, and difficulty in meeting the measurement requirements of electromagnetic railguns.

[0039] Therefore, this embodiment provides as follows Figures 2a-2b A rapid deployment device for electromagnetic orbit magnetic probe arrays was developed to improve the installation flexibility of magnetic probe arrays.

[0040] like Figures 2a-2b As shown in the figure, this embodiment provides a rapid deployment device for an electromagnetic track magnetic probe array. The magnetic probe array includes multiple magnetic probes 1 arranged along the length of the track. Each magnetic probe 1 is respectively provided with a spacing adjustment mechanism 2 and a height adjustment mechanism 3. The spacing adjustment mechanism 2 is fixedly connected to the magnetic probe 1 to adjust the spacing between adjacent magnetic probes 1. The height adjustment mechanism 3 is fixedly connected to the spacing adjustment mechanism 2 to adjust the height of the magnetic probe 1.

[0041] It is understood that the position of the magnetic probe 1 relative to the track length direction can be flexibly adjusted through the spacing adjustment mechanism 2, and the height position of each magnetic probe 1 can be flexibly adjusted through the height adjustment mechanism 3. This makes the test position setting of the magnetic probe 1 within the track more accurate, applicable to various types of track speed measurement conditions, and improves the applicability of electromagnetic track speed measurement. The electromagnetic track magnetic probe array rapid deployment device provided in this embodiment can achieve integrated probe array, rapid and stable installation, convenient adjustment, and precise spacing feedback, improving measurement accuracy and operational convenience.

[0042] Based on the above solution, this embodiment can be further improved as follows.

[0043] In one possible embodiment, such as Figure 3 The diagram shows a schematic of the spacing adjustment mechanism 2 corresponding to a certain magnetic probe 1. Figure 2a and Figure 3As shown, the magnetic probe 1 is set perpendicular to the length direction of the track. One end of the magnetic probe 1 is connected to the movable end of the spacing adjustment mechanism 2, and the other end of the magnetic probe 1 is set towards the center of the track axis.

[0044] Understandably, setting the magnetic probe 1 perpendicular to the length of the track allows for more accurate detection of changes in the magnetic field generated by the movement of the armature, thus improving the accuracy of electromagnetic track speed measurement.

[0045] In one possible embodiment, such as Figure 3 As shown, the spacing adjustment mechanism 2 includes a lead screw assembly 201, a probe mounting base 202, and a displacement detection module (not shown in the figure). The linear motion direction of the lead screw assembly 201 is arranged along the length of the track. The probe mounting base 202 is connected to the linear motion end of the lead screw assembly 201. The magnetic probe 1 is mounted on the probe mounting base 202. The displacement detection module is disposed on the lead screw assembly 201 to detect the linear motion displacement of the lead screw assembly 201.

[0046] It is understandable that the magnetic probe 1 is mounted on the linear motion end of the lead screw assembly 201 via the probe mounting base 202. The lead screw assembly 201 converts the rotational motion of its own motor into linear motion and outputs it to the magnetic probe 1, thereby enabling the magnetic probe 1 to be displaced.

[0047] The displacement detection module can be implemented using a motor encoder, potentiometer, or photoelectric ranging sensor. For example, by detecting the rotation angle of the motor in the lead screw assembly 201 using a motor encoder, the displacement of the magnetic probe 1 driven by the lead screw assembly 201 to perform linear motion can be obtained through calculation. Based on the linear motion displacement of multiple magnetic probes 1, the distance between adjacent magnetic probes 1 can be calculated. Alternatively, the displacement of the magnetic probe 1 can be detected using a potentiometer, and then the displacement of the magnetic probe 1 can be calculated. Similarly, a photoelectric sensor can be used to directly measure the distance between adjacent magnetic probes 1. By using the detected distance between adjacent magnetic probes 1, the motion control of the lead screw assembly 201 can be optimized in reverse, achieving more precise adaptive adjustment of the magnetic probe 1 position.

[0048] In one possible embodiment, the adjacent lead screw assembly 201 is further provided with a track clamping assembly (not shown in the figure). The track clamping assembly is used to install the lead screw assembly 201 close to the side wall of the track after the position adjustment of the magnetic probe 1 is completed. According to actual needs, the track clamping assembly can be set on the fixing part of the lead screw assembly 201 or the height adjustment mechanism 3 to fix the magnetic probe 1.

[0049] In one possible embodiment, such as Figure 4 and Figure 5As shown, the height adjustment mechanism 3 includes a vertical telescopic frame 301 and a leveling frame 302 arranged sequentially from top to bottom. The upper end of the vertical telescopic frame 301 is connected to the fixed end of the lead screw assembly 201, and the lower end of the vertical telescopic frame 301 is connected to the fixed part of the leveling frame 302. The leveling frame 302 has multiple leveling feet 302b, and the height of each leveling foot 302b can be adjusted individually.

[0050] Understandably, the vertical telescopic frame 301 of the height adjustment mechanism 3 is mainly used for coarse adjustment of the height of the magnetic probe 1 through vertical telescopic movement. After the initial height adjustment is completed, the height can be finely adjusted by the leveling frame 302, and the levelness of the magnetic probe 1 can also be further adjusted by the leveling frame 302. Through the dual height adjustment of the vertical telescopic frame 301 and the leveling frame 302, the accuracy of the height adjustment of the magnetic probe 1 can be improved.

[0051] In one possible embodiment, such as Figure 5 As shown, the leveling frame 302 includes a central base 302a and at least three leveling feet 302b. The upper end of the central base 302a is fixedly connected to the lower end of the vertical telescopic frame 301 to prevent the lower end of the vertical telescopic frame 301 from falling off the central base 302a. One end of each of the at least three leveling feet 302b is tangent to and hinged to the outer wall of the central base 302a. All the leveling feet 302b are arranged spirally around the central base 302a. Each leveling foot 302b can rotate along its corresponding hinge point, thereby adjusting the vertical height of the leveling foot 302b. Figure 5 Taking the example of a device with three leveling feet 302b, the three leveling feet 302b form a stable three-point support, and the height of each of the three points can be adjusted by rotating them separately.

[0052] like Figure 5 As shown, to increase the durability of the position after height adjustment and the reliability of the connection between the center seat 302a and the vertical telescopic frame 301, a locking structure 301a is provided between the center seat 302a and the vertical telescopic frame 301. The locking structure 301a here can preferably be a quick-locking handle (such as...). Figure 5 As shown in the figure, the installation and fixing can be completed quickly by hand or with simple tools by means of eccentric wheel locking or ratchet locking.

[0053] In one possible embodiment, the device further includes an axial telescopic mechanism 4, which is coaxially arranged with the magnetic probe 1, and the magnetic probe 1 is mounted on the linear motion end of the spacing adjustment mechanism 2 via the axial telescopic mechanism 4. That is, the axial telescopic mechanism 4 is disposed between the magnetic probe 1 and the spacing adjustment mechanism 2, and when it is telescopically extended, it can adjust the magnetic probe 1 to move towards or away from the track axis.

[0054] As a preferred embodiment, the axial telescopic mechanism 4 is a sleeve telescopic structure, a spiral telescopic mechanism, or a linear sliding telescopic mechanism.

[0055] This utility model provides a rapid deployment device for an electromagnetic track magnetic probe array, which enables integrated deployment of the probe array, rapid and stable installation, convenient adjustment, and precise spacing feedback, thereby improving measurement accuracy and ease of operation. Its advantages are mainly reflected in the following aspects:

[0056] 1. Rapid deployment and high flexibility: Through integrated design, modular components and quick-locking structure 301a, installation and commissioning time is greatly reduced, and it can adapt to various track types and complex installation environments.

[0057] 2. Improved measurement accuracy: It enables precise adjustment of the spacing of magnetic probe 1 and real-time software feedback of its true value, eliminating systematic errors caused by fixed spacing or inaccurate estimation.

[0058] 3. Convenient and efficient operation: The intuitive adjustment method and clear parameter feedback simplify the operation process.

[0059] 4. Enhanced system adaptability: The spacing of magnetic probe 1 can be flexibly adjusted according to different armature speeds, signal strengths and other factors to optimize measurement results.

[0060] 5. Stable and reliable structure: The carefully designed horizontal and vertical adjustment mechanism and locking mechanism ensure stability and repeatability during dynamic measurement.

[0061] By adopting this multifunctional adaptive orbital magnetic probe array rapid deployment structure, the overall performance and user experience of high-speed magnetic field velocimetry devices can be significantly improved.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
