Description

Technical Field

[0001] This utility model relates to the field of rail quality inspection technology, and in particular to an intelligent image acquisition device for rail defects with a protective structure. Background Technology

[0002] As a fundamental infrastructure for railway transportation, the surface and internal defects of rails directly affect the safety of train operation. With the continuous development of technology, intelligent detection technology based on image recognition is gradually being applied to the field of rail inspection.

[0003] Most current intelligent rail defect image acquisition devices are used for inspection during off-peak hours at night. However, the protective structure of these devices is relatively limited. When operating in rainy weather, the image acquisition lens is easily affected by rainwater, resulting in blurred images. This limits the device's operating conditions. The image acquisition equipment is also easily damaged or obstructed by flying stones, fallen leaves, etc., affecting the normal use of the device and shortening its service life.

[0004] Therefore, given the limited protective effect of existing intelligent rail defect image acquisition devices, an intelligent rail defect image acquisition device with a protective structure can be designed. By acquiring images in a sealed environment, the image acquisition lens is sealed and protected inside, avoiding the influence of the external environment on the image acquisition equipment. This ensures that the device can stably perform safety inspections and defect location image acquisition and processing even in rainy weather, extending the service life of the device and effectively enhancing its practical value. Utility Model Content

[0006] The technical solution of this utility model is as follows: a rail defect image intelligent acquisition device with protective structure, including a device body, a moving mechanism, an image acquisition component, a protective cover, a through groove, a wedge block, a sliding roller, a side baffle and a main light source. Two sets of moving mechanisms are symmetrically arranged on both sides of the device body. An image acquisition component is arranged on one side of the moving mechanism. A protective cover is arranged on the outside of the image acquisition component. Through grooves are opened on the bottom surface of the front and rear ends of the protective cover. A wedge block is arranged at the front end of the outer side of the protective cover. A sliding roller is arranged at the top of the through groove. Side baffles are arranged at the bottom ends of the left and right sides of the protective cover. Two sets of main light sources are symmetrically arranged at the top of the inner side of the protective cover.

[0007] Preferably, the device body controls the moving mechanism to move along the rail track at a certain speed according to a set route. The image acquisition component detects damaged parts of the rail and acquires images of the corresponding defect locations. The image acquisition component is protected by a protective cover, and the rail passes through the protective cover via a through groove. When the moving mechanism moves, wedge blocks clear obstacles such as fallen leaves and garbage from the rail surface to the outside of the rail. At the same time, the sliding roller rotates close to the rail surface, ensuring the stable synchronous movement of the protective cover along the rail. Side baffles further protect the image acquisition component from bottom to top. The main light source ensures sufficient light inside the protective cover when acquiring defect images, thereby avoiding the influence of the external environment on the image acquisition equipment. This ensures stable and safe rail inspection and defect location image acquisition and processing even in rainy weather, enhancing the practical value of the device.

[0008] Preferably, the device body has a built-in wireless signal transmitting mechanism, the driving mechanism of the moving mechanism is electrically connected to the device body, the sliding roller is rotatably connected to the protective cover, the outer side of the sliding roller is rotatably connected to the upper surface of the rail, and the side baffle is inclined towards the rail with an inclination angle ranging from 30° to 60°.

[0009] Preferably, the image acquisition component includes an image acquisition base, a first fixed base, and an infrared defect detector. The image acquisition base is located at the top of the moving mechanism and is electrically connected to the device body. The first fixed base is located at the front end of the image acquisition base, and the infrared defect detector is located at the bottom end of the first fixed base and is electrically connected to the image acquisition base.

[0010] Preferably, the image acquisition component also includes a second fixed base, an upper acquisition lens, and a first auxiliary light source. The second fixed base is located at the rear end of the image acquisition base, and the upper acquisition lens is located on one side of the second fixed base. The upper acquisition lens is electrically connected to the image acquisition base, and two sets of first auxiliary light sources are symmetrically arranged on one side of the second fixed base.

[0011] Preferably, the image acquisition component also includes a third fixed base, a side acquisition lens, and a second auxiliary light source. Two sets of third fixed bases are symmetrically arranged at the bottom of both sides of the moving mechanism. A side acquisition lens is arranged on the inner side of the third fixed base, and two sets of second auxiliary light sources are symmetrically arranged on one side of the third fixed base.

[0012] Preferably, the side acquisition lenses are symmetrically arranged on both sides of the rail, and the side acquisition lenses are electrically connected to the image acquisition base. The starting mechanisms of the main light source, the first auxiliary light source, and the second auxiliary light source are electrically connected to the image acquisition base.

[0013] Preferably, a display screen is provided at the front end of the device body, and a transparent protective plate is provided at the front end of the display screen.

[0014] The beneficial effects of this utility model are: During inspection, the device's main control mechanism moves along the rail track at a certain speed along a set route, comprehensively detecting damaged parts of the rail and acquiring images of the corresponding defect locations. A protective cover blocks rainwater and fallen leaves from affecting image acquisition. The main light source ensures sufficient light inside the protective cover when acquiring defect images. As the moving mechanism moves, the rail passes through the protective cover via a slot. Wedge blocks clear obstacles such as fallen leaves and debris from the rail surface to the outside of the rail. Sliding rollers rotate close to the rail surface, ensuring the protective cover moves stably and synchronously along the rail. In addition, side baffles further ensure that the image acquisition operation is not affected by external factors from bottom to top. This addresses the problem that most intelligent rail defect image acquisition devices have limited protective structures, restrict the conditions for use, and are easily damaged or have their view obstructed by flying stones, fallen leaves, etc., thus enhancing the device's practical value.

Two sets of moving mechanisms 2 are symmetrically arranged on both sides of the device body 1. The driving mechanism of the moving mechanism 2 is electrically connected to the device body 1, thereby driving the device body 1 to move along a set route. An image acquisition component is located on one side of the moving mechanism 2 for rail defect inspection. (Figure) The outer side of the acquisition component is equipped with a protective cover 4. The bottom surface of the front and rear ends of the protective cover 4 is provided with through grooves 5. The front end of the outer side of the protective cover 4 is provided with a wedge block 501. The bottom end of the wedge block 501 has a certain gap with the upper surface of the rail. The top of the through groove 5 is provided with a sliding roller 6. The sliding roller 6 is rotatably connected to the protective cover 4. The outer side of the sliding roller 6 is rotatably connected to the upper surface of the rail. The bottom ends of the left and right sides of the protective cover 4 are provided with side baffles 7. The side baffles 7 are inclined towards the rail. The inclination angle range is 30°~60°, so that the side baffles 7 can block rainwater from dripping into the protective cover 4 to a certain extent. The top of the inner side of the protective cover 4 is symmetrically provided with two sets of main light sources 8.

[0018] Please see Figure 4 and Figure 5In this embodiment, the image acquisition component includes an image acquisition base 301, a first fixed base 302, an infrared defect detector 303, a second fixed base 304, an upper acquisition lens 305, a first auxiliary light source 306, a third fixed base 307, a side acquisition lens 308, and a second auxiliary light source 309. The top of the moving mechanism 2 is provided with the image acquisition base 301, which is electrically connected to the device body 1. The front end of the image acquisition base 301 is provided with the first fixed base 302, and the bottom end of the first fixed base 302 is provided with the infrared defect detector 303. The detector 303 is electrically connected to the image acquisition base 301. A second fixed base 304 is located at the rear end of the image acquisition base 301. An upper acquisition lens 305 is located on one side of the second fixed base 304 and is electrically connected to the image acquisition base 301. Two sets of first auxiliary light sources 306 are symmetrically arranged on one side of the second fixed base 304. Two sets of third fixed bases 307 are symmetrically arranged at the bottom ends of both sides of the moving mechanism 2. Side acquisition lenses 308 are located inside the third fixed bases 307 and are symmetrically arranged on both sides of the rail. The side acquisition lenses 308 are connected to the image acquisition base 301. The image acquisition base 301 is electrically connected to the image acquisition base 301. Two sets of second auxiliary light sources 309 are symmetrically arranged on one side of the third fixed base 307. The starting mechanisms of the main light source 8, the first auxiliary light source 306, and the second auxiliary light source 309 are electrically connected to the image acquisition base 301. The position of the infrared defect detector 303 is fixed by the first fixed base 302. The infrared defect detector 303 is used to detect the quality of the rail. The upper acquisition lens 305 is fixed by the second fixed base 304, and the position of the side acquisition lens 308 is fixed by the third fixed base 307. When a defect is detected, the infrared defect detector 303 sends a signal to the image acquisition base. Image acquisition base 301 sends an operation command to activate the upper acquisition lens 305 and the side acquisition lens 308. At the same time, image acquisition base 301 turns on the first auxiliary light source 306 and the second auxiliary light source 309. The upper acquisition lens 305 acquires images of the defective parts from above the rail, and the first auxiliary light source 306 enhances the light acquired by the upper acquisition lens 305. The side acquisition lens 308 acquires images of the defective parts from both sides of the rail, and the second auxiliary light source 309 enhances the light acquired by the side acquisition lens 308, thereby ensuring the clarity of the acquired images.

[0019] Please see Figure 2 In this embodiment, a display screen 101 is provided at the front end of the device body 1, and a transparent protective plate 102 is provided at the front end of the display screen 101. The operating status of the device body 1 is displayed through the display screen 101, and the display screen 101 is protected by the transparent protective plate 102.

[0020] During the inspection, the device body 1 controls the moving mechanism 2 to move along the rail track at a certain speed according to the set route. The wedge block 501 is used to remove obstacles such as fallen leaves and garbage from the surface of the rail to the outside of the rail. The device body 1 is observed through the transparent protective plate 102 and the display screen 101 is used to understand the operating status of the device body 1. The quality of the rail is detected by the infrared defect detector 303 on the first fixed seat 302. Meanwhile, the image acquisition base 301 and the acquisition lens are protected by the protective cover 4. When the moving mechanism 2 moves, the rail passes through the through groove 5 through the protective cover 4, and the sliding roller 6 rotates synchronously against the surface of the rail. The side baffle 7 further ensures that the image acquisition operation is not affected by the outside from bottom to top. When a defect is detected, the infrared defect detector 303 sends an operation command to the image acquisition base 301, which in turn sends an image acquisition command to the device body 1. The device body 1 controls the main light source 8 to turn on, and the image acquisition base 301 controls the upper acquisition lens 305 and the side acquisition lens 308 to start. At the same time, the image acquisition base 301 turns on the first auxiliary light source 306 and the second auxiliary light source 309. The upper acquisition lens 305 of the second fixed base 304 acquires images of the defective part from above the rail, and the side acquisition lens 308 of the third fixed base 307 acquires images of the defective part from both sides of the rail. The image data is transmitted to the device body 1 through the image acquisition base 301. Finally, the acquired images are sent to the relevant equipment of the staff through the wireless transmission mechanism of the device body 1.

[0021] Through the above steps, the moving mechanism 2, controlled by the device body 1, moves along the rail track at a certain speed along a set route. The image acquisition component detects damaged parts of the rail and acquires images of the corresponding defect locations. The image acquisition component is protected by the protective cover 4, allowing the rail to pass through the through groove 5. When the moving mechanism 2 moves, the wedge block 501 removes obstacles such as fallen leaves and garbage from the rail surface to the outside of the rail. At the same time, the sliding roller 6 rotates close to the rail surface, ensuring that the protective cover 4 moves stably and synchronously along the rail. The side baffle 7 further protects the image acquisition component from bottom to top. The main light source 8 ensures sufficient light inside the protective cover 4 when acquiring defect images, thereby avoiding the influence of the external environment on the image acquisition equipment and ensuring stable safety inspection and defect location image acquisition and processing of the rail even in rainy weather.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
