[0028] See also Figures 1 to 7 A warning device for highway maintenance and construction includes a chassis 1 and a display screen 2, the display screen 2 is connected to the chassis 1, and also includes a radar 3, a camera assembly 4, a flashing light 5, a tweeter 8 and a battery 10. The radar 3 is connected to the top of the chassis 1, the camera assembly 4 is connected to the top of the chassis 1, the flashing light 5 is symmetrically connected on both sides of the length direction of the radar 3, the tweeter 8 is symmetrically connected on both sides of the length direction of the chassis 1, and the battery 10 is connected to the side of the chassis 1 away from the display screen 2.

[0029] like Figure 3 and Figure 6 As shown, the camera assembly 4 is rotatably connected to the chassis 1 via a damping shaft 41 , and a slot corresponding to the position of the camera assembly 4 is provided on the chassis 1 .

[0030] like Figure 3 , Figure 6 and Figure 7 As shown, the chassis 1 is symmetrically connected to two sides of the length direction with reflective strip rolls 6, and the reflective strip rolls 6 are connected to pull rings 61; the reflective strip rolls 6 are internally connected with a clockwork spring, and when not in use, the reflective strips will be automatically retracted after being loosened and fixed.

After the reflective strip is pulled out, the position of the spotlight 7 is adjusted so that the driver can notice the reflective strip even if the driving light is not turned on.

[0032] like Figure 3 As shown, the chassis 1 is also connected to a solar panel 9, one end of the solar panel 9 close to the bottom of the chassis 1 is hinged to two first legs 91, and the other end of the first leg 91 is hinged to a position close to the top of the chassis 1 away from the display screen 2; one end of the solar panel 9 close to the top of the chassis 1 is hinged to two second legs 92, and the top of the chassis 1 has slots corresponding to the second legs 92 after the solar panel 9 is supported.

[0033] like Figure 2 and Figure 4 As shown, the battery 10 is a detachable battery, and a charging port is also provided on the battery 10.

[0034] Principle and operation process

[0035] The invention adopts a new type of controller to control each component. During the road maintenance operation, the equipment is assumed to be in the middle of the maintenance lane, and the pull ring 61 is pulled to pull out the reflective strip. The pulled-out length needs to cover the entire lane width. Then the reflective strip is fixed on an ice cream barrel or other structure. The content displayed on the display screen 2 is set on the controller. The radar 3 and the camera assembly 4 are used in conjunction. The radar 3 is used to monitor the approaching situation of the vehicle, and the camera assembly 4 is used to capture the real-time image of the construction area. When the radar 3 detects that the distance of the vehicle is less than 50 meters, it will send a signal to the controller. The controller controls the flashing light 5 to increase the brightness and flashing frequency, and turns on the tweeter 8 to emit a warning sound to further warn the driver that the road ahead is impassable. The reflective strip roll 6 with a spring can be pulled out when in use and automatically recovered when it needs to be stored. At the same time, a spotlight 7 with adjustable direction is arranged next to the reflective strip roll 6. The position of the spotlight 7 can be adjusted after the reflective strip is pulled out to illuminate the reflective strip, so that the driver can notice the position of the reflective strip even if the driving light is not turned on.

[0036] The camera assembly 4 of the utility model adopts a rotatable structure, and a slot corresponding to the camera assembly 4 is provided on the top of the chassis 1, so that the camera assembly 4 can be stored during transportation and folded open when in use. The rotatable structure enables the camera assembly 4 to detect oncoming vehicles at a higher height, thereby improving the accuracy of recognition;

[0037] The novel solar panel 9 is a retractable structure. When in use, the solar panel 9 is pulled away from the chassis 1. Through the rotation of the first leg 91, the solar panel 9 can be pulled to the top of the chassis 1. At this time, the second leg 92 is rotated and inserted into the slot provided on the chassis 1. The solar panel 9 will be temporarily fixed above the chassis 1. Solar energy can be used to store energy in the battery 10, and strong sunlight can be blocked to avoid interference with the radar 3 and the camera assembly 4 and the issuance of error information. At the same time, it can also act as a canopy on rainy days to protect the radar 3 and the camera assembly 4 from retaining rainwater and reducing the detection accuracy.

[0038] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
