DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The following will further elaborate on this application in conjunction with the attached Figures 1-4 drawings for a more detailed description.
[0020] An embodiment of this application discloses a damage sensing device for road traffic signs. Referring to Figures 1-4 , it includes a base 1, on which a vertical rod 2 is fixed. At the top of the vertical rod 2, there is a control box 6. Above the interior of the control box 6, a controller 19 is installed. At the bottom of the controller 19, there is a GPRS information transmission module 20. At the bottom of the base 1, a set of moving wheels are connected by screws and are set to be movable, facilitating flexible use according to the road traffic conditions. On both sides of the outer wall of the base 1, fixing plates 16 are welded. At the bottom end of the fixing plates 16, mounting bases 17 are connected. At the corners of the outer wall of the mounting bases 17, positioning blocks 18 are integrally formed, which can position the mounting bases 17. During installation, the positioning of the base 1 can be completed only by connecting the fixing plates 16 with the mounting bases 17, thereby fixing the indicating position of the vertical rod 2.
[0021] As Figures 1-2 shown, a set of sliding rod sleeves 3 are detachably arranged outside the vertical rod 2. On one side of the sliding rod sleeve 3, a support crossbar 4 is fixed. On the support crossbar 4, a road traffic sign 5 is installed. At the back of the road traffic sign 5, an infrared distance measuring instrument 8 is installed, which is used to monitor the distance change between the road traffic sign 5 and the preset position in real time. When the road traffic sign 5 is impacted or damaged and its position deviates, the infrared distance measuring instrument 8 will immediately sense this change and trigger the alarm system. The alarm system is connected to the GPRS information transmission module 20 through the built-in controller 19, and the alarm signal is sent to the information center in real time so that timely measures can be taken for repair.
[0022] As Figures 2-3 shown, the top of the vertical rod 2 is connected to a top frame 7. Outside the top frame 7, there is a monitoring mechanism. The monitoring mechanism includes a gear ring 9 fixed to the outside of the top frame 7, a connecting frame 12 arranged outside the gear ring 9, and a camera 15 installed inside the connecting frame 12. Through the camera 15, the road traffic conditions and the damage conditions of the road traffic sign 5 can be monitored. At the top of the gear ring 9, a support frame 10 is fixed. At the top of the support frame 10, a support bent rod 11 is rotatably installed. One end of the support bent rod 11 is fixedly connected to the connecting frame 12 to provide a supporting effect. At the top of the connecting frame 12, a servo motor 14 is installed. The output end of the servo motor 14 extends into the connecting frame 12 and is drivingly connected to a gear 13. When the servo motor 14 works, it can drive the gear 13 to mesh with the gear ring 9. Then, the support bent rod 11 will perform a circumferential movement on the support frame 10, so that the corresponding monitoring position and angle can be adjusted through the camera 15, facilitating the real-time monitoring of the road traffic conditions.
[0023] The implementation principle of a damage induction device for a road traffic sign in an embodiment of the present application is as follows: During use, first fix the installation base 17 at the corresponding position on the road. Then move the base 1 onto the installation base 17, and connect the fixing plate 16 and the installation base 17 with bolts to complete the positioning of the base 1. During daily use, since an infrared rangefinder 8 is provided on the rear end face of the traffic sign 5 to monitor the change in the distance between the traffic sign 5 and the preset position in real time. When the traffic sign 5 is impacted or damaged and its position shifts, the infrared rangefinder 8 will immediately sense this change and trigger the controller 19. The controller 19 is connected to the GPRS information transmission module 20 to send the alarm signal to the information center in real time for timely measures to be taken for repair. At the same time, the servo motor 14 can also be driven to rotate the gear 13 to engage with the gear ring 9, and then the support bent rod 11 can be pushed to drive the camera 15 inside the connecting frame 12 to perform a circumferential movement on the support frame 10, so as to conveniently adjust the monitoring direction and angle of the camera 15 according to the road traffic conditions, and accurately sense the minute displacement change of the traffic sign 5 to discover the damage situation in time.
