Abstract
Description
Technical Field
[0001] This utility model relates to the field of signal acquisition equipment technology, and in particular to an ultrasonic signal acquisition cover. Background Technology
[0002] As a key component of the train braking system, the brake lines are crucial for the safe operation of trains in the railway transportation sector. Inspection of train brake lines is a critical link in ensuring railway transportation safety, directly impacting train safety and stability. Traditional inspection methods suffer from low accuracy, inefficiency, and the risk of damage to the lines, making them unsuitable for the urgent needs of efficient, accurate, and safe inspection in modern railway transportation. To address this, ultrasonic inspection instruments for train brake lines have emerged, enabling high-precision, rapid, and non-destructive testing of internal defects or leaks in train brake lines. This provides a more efficient, reliable, and safe inspection solution for the railway maintenance field.
[0003] Currently, there is a lack of a signal acquisition cover that allows the detection sensors to be distributed circumferentially along the train's brake lines, facilitating signal acquisition.
[0004] Therefore, an ultrasonic signal acquisition cover is proposed to address the above problems. Utility Model Content
[0005] This invention addresses the shortcomings of existing technologies by developing an ultrasonic signal acquisition cover. This invention allows the detection sensors to be distributed circumferentially along the train's brake lines, facilitating signal acquisition.
[0006] The technical solution to the problem solved by this utility model is as follows: This utility model provides an ultrasonic signal acquisition cover, including: a handle assembly and an acquisition assembly; the handle assembly includes a handle, the handle is connected to a mounting plate, the mounting plate is connected to a slotted protective shell, and the slotted protective shell is provided with a set of straight slots; the acquisition assembly includes a set of arc plates, each arc plate is connected to a set of symmetrical mounting seats, a detection sensor is installed in the groove of each mounting seat, each arc plate is connected to an L-rod, each L-rod is connected to a slider, and each slider is nested in the corresponding straight slot. By using an adjustable arc plate, it is convenient to realize the detection sensor ringing around the train brake pipeline, thus facilitating signal acquisition. Existing signal acquisition covers require close contact with the train brake pipeline for signal collection. Compared with existing acquisition covers, the detection sensors of this utility model are distributed in a ring around the train brake pipeline, making detection more convenient.
[0007] As an optimization, a power assembly is also included. This power assembly includes a clearance plate connected to a limiting protrusion ring.

By employing the clearance plate, the position of the detection sensor can be adjusted during its rotation.
[0008] As an optimization, the slotted protective shell is connected to a motor via a motor bracket, the motor's output shaft is connected to a gear, and the clearance plate is connected to a half-gear ring, with the gear meshing with the half-gear ring. By using a motor to drive the gear and gear ring meshing, the clearance plate is rotated.
[0009] As an optimization, a power signal cable is installed inside the handle. Each mounting base is connected to the corresponding detection sensor via an end conduit, and each L-shaped rod is connected to a middle conduit. Each middle conduit passes through the corresponding arc plate. Branch wires of the power signal cable pass through the middle and end conduits and connect to the corresponding detection sensors. Sealant is used to secure the branch wires of the power signal cable at both ends of the middle and end conduits.

[0010] As an optimization, each of the straight grooves is provided with a guide rod, and each guide rod passes through the corresponding slider. By providing guide rods, the stability of the slider movement is increased.

[0027] like Figures 1 to 6As shown in Embodiment 1: An ultrasonic signal acquisition cover includes a handle assembly 1 and an acquisition assembly 3. The handle assembly 1 includes a handle 12, which is connected to a mounting plate 13. The mounting plate 13 is connected to a slotted protective shell 14, which has a set of straight slots 16. The acquisition assembly 3 includes a set of arc plates 31, each arc plate 31 being connected to a set of symmetrical mounting seats 32. A detection sensor 33 is installed in the groove of each mounting seat 32. Each arc plate 31 is connected to an L-shaped rod 35, and each L-shaped rod 35 is connected to a slider 37. Each slider 37 is nested in the corresponding straight slot 16. By using an adjustable arc plate 31, it is convenient to realize the detection sensor 33 encircling the train brake pipeline, thus facilitating signal acquisition. Existing signal acquisition covers require close contact with the train brake pipeline for signal collection. Compared with existing acquisition covers, the detection sensor 33 of this invention is distributed in a ring around the train brake pipeline, making detection more convenient. When inspecting Φ65mm brake pipes, the defect detection rate increased from 82% to 98%.
[0028] The detection sensors 33 are arranged at equal angular intervals to form a signal receiving array, and the central axes of each sensor intersect on the central axis of the area formed by the arc plate 31. By using the position-adjustable arc plate 31, the detection sensors 33 are distributed circumferentially along the train brake pipeline to form a ring signal acquisition array, which can collect signals more comprehensively and improve detection accuracy.
[0029] The detection sensor 33 is the SPW2430 silicon microphone sensor. It is a small, high-performance analog MEMS silicon microphone widely used in sound detection and audio signal acquisition.
[0030] A set of arc plates 31 forms an area that matches the train brake lines. The corners of the set of arc plates 31 are rounded and covered with rubber to prevent them from contacting the train brake lines and causing damage.
[0031] It also includes a power assembly 2, which includes a clearance plate 21 connected to a limiting protrusion 26. The slotted protective shell 14 is provided with a protrusion groove 15, and the limiting protrusion 26 is disposed within the protrusion groove 15. The clearance plate 21 is provided with a set of eccentric grooves 22, and each L-rod 35 is connected to a circular tube 38, with each circular tube 38 disposed within a corresponding eccentric groove 22. By employing the clearance plate 21, the position of the detection sensor 33 can be adjusted during its rotation.
[0032] The corners of the clearance plate 21 are rounded and covered with rubber to prevent them from coming into contact with the train's brake lines and causing damage.
[0033] The slotted protective shell 14 is connected to a motor 24 via a motor bracket. The output shaft of the motor 24 is connected to a gear 25. The clearance plate 21 is connected to a semi-gear ring 23, and the gear 25 meshes with the semi-gear ring 23. By using the motor 24 to drive the gear ring, the clearance plate 21 is rotated.
[0034] Each of the straight grooves 16 is provided with a guide rod 17, and each guide rod 17 passes through the corresponding slider 37. By providing the guide rods 17, the stability of the slider 37's movement is increased.
[0035] The workflow of this embodiment is as follows:
[0036] Connect power signal line 11 to the host.
[0037] The train brake line passes between the slotted protective shell 14, the clearance plate 21 and the two adjacent arc plates 21, so that the train brake line is in the middle position of a set of detection sensors 33.
[0038] During installation, ensure that the train brake line can pass smoothly through the space between the slotted protective shell 14, the clearance plate 21 and the arc plate 21 to avoid damage to the line.
[0039] The motor 24 is controlled to rotate, which drives the gear 25 to rotate. The gear 25 drives the half gear ring 23 to rotate, which drives the clearance plate 21 to rotate. The clearance plate 21 drives the limiting convex ring 26 to rotate along the convex ring groove 15. The clearance plate 21 drives the round tube 38 to move along the eccentric groove 22, realizing the overall movement of the acquisition component 3. The slider 37 moves along the guide round rod 17 in the straight groove 16, so that the detection sensor 33 is close to the train brake line.
[0040] During the debugging process, it is necessary to ensure that the rotation direction of motor 24 is correct and to avoid collision between the detection sensor 33 and the train brake line.
[0041] Operate the host computer to enable the detection sensor 33 to collect signals.
[0042] Example 2: This example further elaborates on Example 1. A power signal line 11 is installed inside the handle 12. Each mounting base 32 is connected to the corresponding detection sensor 33 via an end conduit 34. Each L-shaped rod 35 is connected to an intermediate conduit 36, and each intermediate conduit 36 passes through the corresponding arc plate 31. Branch wires of the power signal line 11 pass through the intermediate conduit 36 and the end conduit 34 to connect to the corresponding detection sensor 33. The branch wires of the power signal line 11 are fixed at both ends of the intermediate conduit 36 and the end conduit 34 with sealant. Sufficient length is reserved between the intermediate conduit 36 and the end conduit 34 so that the reserved branch wires will not be taut when the position of the detection sensor 33 is adjusted.
[0043] The power signal line 11 is connected to the detection sensor 33 through the intermediate conduit 36 and the end conduit 34 to prevent the wire from being stretched or damaged when the position of the detection sensor 33 is adjusted.
[0044] Use sealant to secure the power signal line 11 to ensure a firm and reliable connection.
[0045] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
