[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] Example 1, please refer to Figures 1-4The present embodiment provides a rail vehicle lighting device, comprising: a mounting plate 1; a lighting assembly 2, the lighting assembly 2 being fixedly connected to the outer wall of the mounting plate 1; a protective cover 3, the protective cover 3 being fixedly sleeved on the outside of the lighting assembly 2, the protective cover 3 being an important external protective structure to prevent damage to the lighting assembly 2 by external objects; a slot 7, the slot 7 being opened at the bottom of the protective cover 3; an outer wall of the protective cover 3 being fixedly sleeved with an air guide plate 41, the function of the air guide plate 41 being to guide airflow, thereby improving the heat dissipation effect of the lighting device, an air vent 42 being opened on the outer wall of the protective cover 3, a fixing cylinder 43 being fixedly connected to the back of the air guide plate 41, and a front end of the air guide plate 41 being opened. There is an air inlet 44. The inner wall of the fixed cylinder 43 is rotatably connected to a rotating shaft 45, and one end of the rotating shaft 45 passes through the fixed cylinder 43. The outer wall of the rotating shaft 45 is fixedly connected to a blade 46 and a gear A47. The outer wall of the protective cover 3 is rotatably sleeved with a gear ring 48. The outer wall of the gear ring 48 is fixedly connected to a connecting shaft 49. The other end of the connecting shaft 49 is fixedly connected to a magnet A410. The front end of magnet A410 is magnetically connected to a magnet B411. The outer wall of magnet B411 is fixedly connected to a cleaning roller 412. The cleaning roller 412 can effectively clean dust and impurities on the surface of the air vent 42 during rotation, keeping the filter mesh unobstructed. A scraper 413 is provided inside the protective cover 3. The air vents 42 are equidistantly arranged on the outer wall of the protective cover 3, and a filter mesh is provided inside the air vent 42 to prevent dust. When the airflow enters the air vent 42, the filter can effectively block dust and impurities and prevent the air vent 42 from being blocked. This design helps to ensure the smooth flow of air inside the protective cover 3 and avoid overheating or dust accumulation caused by airflow obstruction. Magnet B411 is located at the front end of the air guide plate 41 and is slidably connected to the air guide plate 41. A magnetic block is also provided at one end of the scraper 413 close to the magnet A410, and the scraper 413 is magnetically connected to the magnet A410 through the magnetic block. The outer wall of the protective cover 3 is equipped with a wind-breaking component 5 and a dredging component 6.

[0028] During use, when a vehicle on the track passes the lighting assembly 2, since the vehicle is in a high-speed driving state, an air flow will be generated to blow toward the protective cover 3 and the lighting assembly 2, and due to the action of the wind guide plate 41, the air flow will enter the interior of the protective cover 3 through the air vent 42 and the slot 7, and the filter screen on the surface of the air vent 42 will block impurities and dust to prevent the air vent 42 from being blocked. At the same time, a part of the air flow will enter the interior of the fixed cylinder 43 through the air inlet 44, and then the blade 46 will drive the rotating shaft 45 to rotate, and then the gear A47 fixed on the outer wall of the rotating shaft 45 will rotate accordingly. When the gear A47 rotates, the gear ring 48 meshing with it at the bottom will rotate accordingly, and the gear ring 48 will drive the magnet A410 to rotate through the connecting shaft 49, and the magnet B411 magnetically connected to the front end of the magnet A410 will rotate accordingly, and the magnet B411 will drive the cleaning roller 412 to rotate around the outer wall of the protective cover 3, thereby cleaning the filter, thereby ensuring the smooth flow of the filter, and at the same time, when the magnet A410 rotates, the scraper 413 connected to it through the magnetic block inside the protective cover 3 will rotate accordingly, thereby scraping and cleaning the inner wall of the protective cover 3.

[0029] Example 2, please refer to Figures 1-6 The wind-breaking assembly 5 includes a mounting rod 51, which is fixedly connected to the outer wall of the protective cover 3. One end of the mounting rod 51 is fixedly connected to a horizontal plate 52. A slide groove 53 is provided in the middle of the horizontal plate 52. A slider 54 is slidably connected inside the slide groove 53. The bottom of the horizontal plate 52 is rotatably connected to a transparent plate A55 through a rotating rod. The bottom of the slider 54 is rotatably connected to a transparent plate B56 through a rotating rod. The transparent plate A55 and the bottom of the transparent plate B56 are hingedly connected with a connecting block 57. The inner side of the mounting rod 51 is rotatably connected to a gear B514. The upper end of the slider 54 is fixedly connected to a connecting rod 516. The other end of the connecting rod 516 is fixedly connected to a toothed plate 515. The outer wall of the rotating shaft 45 is equipped with a centrifugal assembly for driving the gear B514. The centrifugal assembly includes a connecting rod A58, which is hinged to the outer wall of the rotating shaft 45. The other end of the rotating shaft 45 is hinged to a centrifugal ball 59, and the interior of the centrifugal ball 59 is hinged to a connecting rod B510. A rotating drum 511 is movably mounted on the outer wall of the rotating shaft 45. The other end of the connecting rod B510 is hinged to the rotating drum 511. One end of the rotating drum 511 is hinged to a moving rod 512, and the other end of the moving rod 512 slides through the mounting rod 51. A conical rubber block 513 is fixedly mounted on the outer wall of the moving rod 512. A toothed plate 515 is located at the upper end of the gear B514 and meshes with it.

[0030] During use, when the vehicle on the track is moving too fast, the rotational speed of the blade 46 and the rotating shaft 45 will then increase. As a result, the rotational speed of the connecting rod A58 on the outer wall of the rotating shaft 45 will increase. Under the action of centrifugal force, the centrifugal ball 59 hinged at its other end will expand outwards. Consequently, the centrifugal ball 59 will drive one end of the connecting rod B510 to move outwards. Then, the other end of the connecting rod B510 will drive the rotating cylinder 511 to slide towards the gear A47 outside the rotating shaft 45. Subsequently, the moving rod 512 at the other end of the rotating cylinder 511 will move towards the protective cover 3. Accordingly, the conical rubber block 513 outside the moving rod 512 will also move along. When the wide part of the conical rubber block 513 contacts the gear B514, it can drive the gear B514 to rotate under sufficient frictional force. Then, the toothed plate 515 meshing with the upper end of the gear B514 will move accordingly. Subsequently, the toothed plate 515 will drive the slider 54 to slide inside the chute 53 through the connecting rod 516. Thus, it can drive one end of the transparent plate B56 to move through the rotating rod. After moving a certain distance, the connecting block 57 at the bottom of the other end of the transparent plate B56 will pull one end of the transparent plate A55 to move. When the slider 54 compresses the spring on the inner wall of the chute 53 until it cannot be compressed further, at this time, the transparent plate A55 and the transparent plate B56 will form a V shape, thereby diverting the airflow brought by the vehicle to both sides, thus improving the stability of the lighting device.

[0031] Embodiment 3, please refer to Figure 1-Figure 7 , a dredging component 6. The dredging component 6 includes a U-shaped plate 61. The inner wall of the U-shaped plate 61 is rotatably connected with a mounting shaft 62. A dredging plate 64 is fixedly sleeved on the outer wall of the mounting shaft 62. One end of the mounting shaft 62 is fixedly connected with a swinging block 63. A torsion spring 65 is arranged between the U-shaped plate 61 and the swinging block 63.

[0032] During use, after the scraper 413 rotates to contact the swing block 63, its continued rotation causes the swing block 63 to swing, thereby driving the mounting shaft 62 to rotate. As the mounting shaft 62 rotates, the dredging plate 64 mounted on the outer wall also begins to rotate, making contact with the slot 7. During this rotation, the dredging plate 64 gradually enters the interior of the slot 7. Through this rotational motion, the dredging plate 64 effectively clears debris and sediment from the slot 7. In particular, when the dredging plate 64 rotates to a 90-degree position, it enters the designed space of the slot 7, thoroughly cleaning the slot and ensuring an unobstructed flow. Simultaneously, after the scraper 413 releases contact with the swing block 63, the reset action of all load-bearing components begins. Under the restoring force of the torsion spring 65, the mounting shaft 62, swing block 63, and dredging plate 64 automatically return to their original positions, ensuring normal operation of the system and the smooth start of the next cleaning cycle. The torsion spring 65 is a key restoring element. Its elasticity provides a stable restoring action, so that the device can operate for a long time and efficiently while avoiding the occurrence of excessive wear or jamming problems.

[0033] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
