[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.

[0025] Referring to Figure 1 、 Figure 2 and Figure 3 , an embodiment provided by the present utility model: a visual monitoring device for track foreign objects, including a mounting rod 1. The mounting rod 1 serves as the main support structure of the entire device, providing an installation basis for other components. A monitoring camera 2 is provided on one side of the mounting rod 1. The monitoring camera 2 is used to collect image information of the track area to detect whether there are foreign objects. A mounting plate 3 is fixedly connected to one side of the outer wall of the mounting rod 1. The mounting plate 3 plays a role in connecting the mounting rod 1 and the mounting frame 4. A mounting frame 4 is fixedly connected to one side of the outer wall of the mounting plate 3. The mounting frame 4 provides a fixed position for components such as a spring 5 and a first mounting block 6. A spring 5 is fixedly connected to one side of the outer wall of the mounting frame 4. The spring 5 can play a buffering role. When the device is subjected to vibration or external impact, the spring 5 can absorb a part of the energy to protect other components from damage. A first mounting block 6 is fixedly connected to one side of the outer wall of the spring 5. The first mounting block 6 is used to connect the arc plate 7. A first mounting block 6 is fixedly connected to one side of the outer wall of the arc plate 7. The arc plate 7 is in contact with the mounting column 14, playing a role in fixing and supporting. The arc plate 7 is in contact with the mounting column 14 on one side of the outer wall. The mounting column 14 may be connected to other components or provide additional support for the device. A clamping assembly for fixing the distance of the arc plate 7 is installed on one side of the outer wall of the first mounting block 6;

[0026] The clamping assembly includes a connecting plate 25. One side of the outer wall of the connecting plate 25 is fixedly connected to one side of the outer wall of the first mounting block 6. The connecting plate 25 serves to connect the first mounting block 6 and the clamping plate 8. The clamping plate 8 is rotatably connected to the outer wall of the connecting plate 25. The clamping plate 8 can clamp the arc-shaped plate 7 by rotation, thereby fixing the distance between the arc-shaped plate 7 and the mounting column 14. A fixed shaft 9 is fixedly connected inside the mounting frame 4. The fixed shaft 9 provides a sliding track for the clamping plate 8, enabling the clamping plate 8 to slide stably. The outer wall of the fixed shaft 9 is slidably connected inside the clamping plate 8. One side of the inner wall of the clamping plate 8 is fixedly connected with an anti-slip pad 10. The anti-slip pad 10 can increase the friction between the clamping plate 8 and the object to be clamped, prevent sliding, and improve the stability of clamping. A fastening assembly for fastening the clamping plate 8 is installed on the outer wall of the clamping plate 8. The fastening assembly includes a second mounting block 11. One side of the outer wall of the second mounting block 11 is fixedly connected to one side of the outer wall of the clamping plate 8. The second mounting block 11 provides an installation position for the bolt 12 and the nut 13. The bolt 12 penetrates through the inside of the second mounting block 11. The bolt 12 and the nut 13 are used in cooperation. By tightening the nut 13, the clamping plate 8 can clamp the arc-shaped plate 7 more tightly, thereby fixing the position of the arc-shaped plate 7. The nut 13 is threadedly connected to the outer wall of the bolt 12.

[0027] Refer to Figure 1 and Figure 4, a rotating shaft 15 is fixedly connected to the upper surface of the monitoring camera 2. The rotating shaft 15 serves to connect the monitoring camera 2 and the mounting rod 1, and at the same time enables the monitoring camera 2 to rotate around the rotating shaft 15, thereby adjusting the shooting angle. The upper surface of the rotating shaft 15 is rotatably connected to the lower side inside the mounting rod 1. A light-shielding cover 16 is fixedly connected to the outer wall of the rotating shaft 15. The light-shielding cover 16 is arranged directly above the monitoring camera 2. The light-shielding cover 16 is used to block strong light and prevent the strong light from having an adverse effect on the shooting effect of the monitoring camera 2. A dust removal component for dust removal is installed on the outer wall of the light-shielding cover 16. A first gear 20 is fixedly connected to the outer wall of the rotating shaft 15. The first gear 20 is used to mesh with the second gear 23 to realize the adjustment of the angle of the monitoring camera 2. An adjustment component for adjusting the angle of the monitoring camera 2 is installed inside the mounting rod 1. The dust removal component includes a protective cover 17. One side of the outer wall of the protective cover 17 is fixedly connected to one side of the outer wall of the light-shielding cover 16. The protective cover 17 serves to protect the blower 18. A blower 18 is disposed through the inside of the light-shielding cover 16. The blower 18 is used to generate an air flow to blow away the dust on the surface of the monitoring camera 2, keep the monitoring camera 2 clean, and ensure that the captured image is clear. A protective cover 19 is disposed outside the outer wall of the blower 18. The protective cover 19 further protects the blower 18 to prevent it from being damaged by external forces. The adjustment component includes a rotating rod 21. The outer wall of the rotating rod 21 is rotatably connected inside the mounting rod 1. The rotating rod 21 is used to drive the lead screw 22 and the second gear 23 to rotate. A lead screw 22 is fixedly connected to the upper surface of the rotating rod 21. The lead screw 22 realizes the fixation and loosening of the second gear 23 through the threaded connection with the threaded block 24. A second gear 23 is fixedly connected to the lower surface of the rotating rod 21. The second gear 23 is meshed with the first gear 20. By rotating the second gear 23 to drive the first gear 20 to rotate, the angle of the monitoring camera 2 is adjusted. A threaded block 24 is threadedly connected to the outer wall of the lead screw 22. The outer wall of the threaded block 24 is in contact with the upper surface of the mounting rod 1. The threaded block 24 is used to fix the second gear 23. When the threaded block 24 is tightened, the second gear 23 cannot rotate, thereby fixing the angle of the monitoring camera 2.

[0028] Working principle: When the foreign object vision monitoring device needs to be installed, first hold the mounting rod 1 by hand and fit the arc-shaped plate 7 against the outer wall of the mounting column 14. At this time, the arc-shaped plate 7 will squeeze the spring 5 on one side of the first mounting block 6, thereby achieving the effect of driving the connecting plate 25 to move. At this time, through the movement of the connecting plate 25, the clamping plate 8 is further driven to slide in a limited manner on the outer wall of the fixed shaft 9. Through the movement of the clamping plate 8, the anti-slip pad 10 is driven to closely adhere to the outer wall of the mounting column 14. After the anti-slip pad 10 is installed, at this time, the bolt 12 is passed through the inside of the second mounting block 11, and then the nut 13 is installed on the outer wall of the bolt 12, thereby achieving the effect of rapid installation;

[0029] Secondly, when it is inconvenient to adjust the angle of the monitoring camera 2 after installation, the rotating rod 21 is rotated at this time to make the second gear 23 mesh and rotate with the first gear 20, so as to drive the monitoring camera 2 to rotate to the area to be detected. At this time, the threaded block 24 is rotated to fix the rotating rod 21, thus achieving the effect of preventing the second gear 23 from rotating. When the sunlight is relatively strong, the glare above the monitoring camera 2 can be blocked by the light-shielding cover 16, so as to prevent the monitoring screen from being overexposed due to strong light. At the same time, when the train passes by the detection device, dust will be carried up and adhered to the outer wall of the monitoring camera 2. At this time, the floating dust on the surface of the monitoring camera 2 is removed by the blower 18, so as to prevent the monitoring screen from being affected. At this time, the protective cover 17 can prevent the blower 18 from being eroded by rainwater.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
