Description

Technical Field

[0001] This utility model relates to the field of image acquisition devices for fault analysis of high-speed trains. Background Technology

[0002] High-speed trains are an important component of my country's railway transportation system, undertaking a large volume of passenger and freight transport tasks. With the continuous expansion of railway transportation, the operating frequency of high-speed trains is increasing year by year, making the safe and stable operation of these trains particularly important. If a high-speed train malfunctions, in addition to potential economic losses, it may also threaten the lives and property of the public. Therefore, improving the accuracy and efficiency of high-speed train fault detection is one of the keys to ensuring railway transportation safety. To achieve this goal, fault detection technology has become a crucial aspect of high-speed train operation and maintenance management.

[0003] Currently, fault detection in high-speed trains typically relies on manual image inspection. This method involves placing cameras along both sides of the railway to capture images of the train as it passes, analyzing the images to determine if any faults exist. However, in existing detection systems, the camera equipment is often directly exposed to the outdoor environment, lacking effective protection measures. Prolonged exposure to harsh weather conditions can cause camera lenses to accumulate dirt and even become damaged, directly affecting the clarity and quality of the images. Especially in adverse weather conditions such as snow, rain, and fog, the lenses are more easily covered, resulting in blurry images and significantly hindering the analysis and judgment of high-speed train faults. Utility Model Content

[0026] like Figures 1 to 6 As shown, an image acquisition device for fault analysis of high-speed trains includes: a mounting rod 1, a protective housing 2, a camera 4, and a drive assembly 3; the upper end of the mounting rod 1 is fixedly connected to the bottom wall of the protective housing 2, the drive assembly 3 is disposed inside the protective housing 2, the protective housing 2 has a notch 21 for the camera 4 to extend out, the camera 4 is connected to the drive assembly 3, and is used to drive the camera 4 to extend out of the notch 21 and retract into the protective housing 2.

[0027] The upper end of the mounting rod 1 is fixedly connected to the bottom wall of the protective housing 2, ensuring that the protective housing 2 is securely installed in the required position. The function of the protective housing 2 is to protect the camera 4 and provide stable support, preventing it from being affected by the external environment. The protective housing 2 is usually made of weather-resistant material to ensure its long-term use is not affected by weather changes. The drive assembly 3 is located inside the protective housing 2 and is tightly integrated with the structure of the protective housing 2. The function of the drive assembly 3 is to control the extension and retraction movement of the camera 4. In practical applications, the drive assembly 3 can be electrically driven, such as a motor, pneumatic device, or other suitable drive method, ensuring that the camera 4 can extend or retract as needed according to a predetermined program. The protective housing 2 has a notch 21, the size and position of which are suitable for the extension and retraction movement of the camera 4. The camera 4 extends through the notch 21 to acquire images. After image acquisition is completed, the drive assembly 3 controls the camera 4 to retract into the protective housing 2. The notch 21 effectively prevents the camera 4 from being exposed to the external environment, thus providing protection.

[0028] Camera 4 is a line-scan camera capable of accurately capturing images of the EMU train's operational status. In actual use, when the EMU enters the image acquisition zone, the drive assembly 3 is activated, causing camera 4 to extend through notch 21 and begin image acquisition. At this time, camera 4 begins capturing relevant images of the EMU, recording any potential malfunctions. Camera 4, through high-resolution image capture technology, can effectively identify abnormalities on the train's surface or during operation. After the EMU passes the image acquisition zone, the drive assembly 3 retracts camera 4 into the protective housing 2 to prevent prolonged exposure to the external environment when no train is running. The protective housing 2 effectively protects camera 4, preventing dirt, dust, rain, snow, and other substances from adhering to the camera lens, ensuring clear images for the next use.

[0029] In this embodiment, the drive assembly 3 includes a mounting plate 31, a lead screw 32, a motor 33, a moving beam 34, and two connecting rods 35. The mounting plate 31 is fixedly installed inside the protective housing 2, providing support for the drive assembly 3. The motor 33 is fixedly connected to the mounting plate 31, and its function is to drive the lead screw 32 to rotate, thereby controlling the movement of the camera 4. One end of the lead screw 32 is connected to the output end of the motor 33, and the other end is rotatably connected to the inner wall of the protective housing 2. The lead screw 32 rotates under the drive of the motor, thereby driving the moving beam 34 to move vertically. The moving beam 34 is slidably connected to the mounting plate 31, and the lead screw 32 passes through the moving beam 34 and is threadedly connected to it, ensuring that the moving beam 34 can move up and down along the rotation direction of the lead screw 32. One end of the connecting rod 35 is rotatably connected to the mounting plate 31, and the other end is rotatably connected to the camera 4, serving to guide and drive the rotation of the camera 4.

[0030] Camera 4 is rotatably connected to moving beam 34 via mounting base 41, which provides a stable mounting position for camera 4. While moving camera 4 moves up and down via moving beam 34, it is controlled to rotate 90 degrees via connecting rod 35, allowing camera 4 to extend out from inside protective housing 2 and acquire images of the train.

[0031] like Figure 4 , Figure 5 and Figure 6 As shown, in actual use, after starting the motor 33, the motor 33 drives the lead screw 32 to rotate, and the lead screw 32 drives the moving beam 34 to move up and down. When the moving beam 34 moves downward, the camera 4 moves downward along with the moving beam 34 and rotates through the connecting rod 35 to complete a 90-degree flip, so that the camera 4 extends out of the notch 21 of the protective housing 2 and begins image acquisition.

[0032] When the train passes through the image acquisition area, camera 4 starts to capture images. After the acquisition is completed, motor 33 drives screw 32 to rotate again, causing moving beam 34 to move upward. At this time, camera 4 moves upward along with moving beam 34 and rotates back to its original position through connecting rod 35 until camera 4 is completely retracted into protective housing 2.

[0033] This process prevents camera 4 from being exposed to the external environment when no trains are passing by, thus avoiding the effects of dirt, rain, snow and other harsh weather, and ensuring the clarity and shooting effect of camera 4 when it is working.

[0034] In this embodiment, the drive assembly 3 further includes two guide rails 36 and two sliders 37; the two guide rails 36 are fixedly connected to the mounting plate 31 and are arranged vertically. The two sliders 37 are slidably connected to the guide rails 36 and fixedly connected to the moving beam 34. The sliding engagement between the sliders 37 and the guide rails 36 ensures the stable movement of the moving beam 34, preventing it from tilting or becoming unstable, thereby improving the accuracy and stability of image acquisition.

[0035] In this embodiment, the camera 4 is rotatably connected to the movable beam 34 via a mounting base 41. The movable beam 34 includes two support arms 341, which are rotatably connected to the mounting base 41. The camera 4 can move up and down under the drive of the movable beam 34, and can also rotate 90 degrees according to the control of the drive component 3, thereby extending and retracting the camera.

[0036] To improve the clarity and quality of images captured by camera 4, this embodiment also includes two light sources 5. The two light sources 5 are respectively positioned on both sides of the protective housing 2 to ensure sufficient illumination of the image acquisition area when a high-speed train passes by, avoiding image blurring or distortion due to insufficient lighting. The light sources 5 can be LED lights or other suitable light sources to meet the lighting needs of different environments.

[0037] In this embodiment, a baffle plate 22 is hinged to the notch 21 of the protective housing 2. When the camera 4 is retracted into the protective housing 2, the baffle plate 22, due to gravity, will be in a vertical position and close the notch 21, preventing damage to the camera 4 from the external environment (such as dust, rain, etc.). When the camera 4 is extended by the drive assembly 3, the camera 4 first contacts the inner wall of the baffle plate 22. As the camera 4 continues to extend, the baffle plate 22 will be pushed and flipped by the camera 4. The flipping of the baffle plate 22 allows the camera 4 to smoothly extend from the notch 21 and begin image acquisition.

[0038] To ensure that the shield 22 can rotate smoothly and to prevent it from interfering with the movement of the camera 4, a contact block 42 is installed on the camera 4 in this embodiment. The contact block 42 is located on the camera 4 and contacts the inner wall of the shield 22 when the camera 4 retracts. During the extension of the camera 4, the contact block 42 pushes the shield 22, causing it to rotate in a predetermined direction until the camera 4 is fully extended beyond the notch 21. The contact block 42 ensures that the shield 22 can rotate smoothly without affecting the normal operation of the camera 4.

[0039] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
