DETAILED DESCRIPTION

[0023] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0024] Embodiment 1: A protective device for highway construction suitable for nighttime work, such as Figure 1-Figure 4 As shown, it includes a fixing frame 1, a base plate 2, a reflector 3, a sliding rod 4, a lighting lamp 5 and a warning mechanism. The bottom of the fixing frame 1 is fixedly connected to the base plate 2, the front and rear sides of the fixing frame 1 are fixedly connected to the reflector 3, the top of the fixing frame 1 is slidably connected to the sliding rod 4 through a damping ring, the top of the sliding rod 4 is rotatably connected to the lighting lamp 5 through a universal wheel, and the fixing frame 1 is provided with a warning mechanism.

[0025] like Figure 3 and Figure 4As shown, the warning mechanism includes a rotating rod 6, a torsion spring 61, a reflective strip 7, a clamping strip 8, a mounting plate 9, a limit strip 10 and an elastic rope 11. The rotating rod 6 is rotatably connected inside the fixed frame 1, a torsion spring 61 is fixedly connected between the rotating rod 6 and the fixed frame 1, a reflective strip 7 is wrapped around the outside of the rotating rod 6, the other end of the reflective strip 7 passes through the fixed frame 1 and is fixedly connected to the clamping strip 8, a mounting plate 9 is fixedly connected to the right side of the fixed frame 1, the front and rear sides of the mounting plate 9 are both slidably connected to the limit strip 10, an elastic rope 11 distributed vertically up and down is fixedly connected between the mounting plate 9 and the limit strip 10, and the clamping strip 8 is squeezed and fitted with the limit strip 10.

[0026] like Figure 3 and Figure 4 As shown, the clamping strip 8 and the limiting strip 10 are both provided with inclined surfaces.

[0027] like Figure 5 As shown, it also includes a contact rod 12, an inclined plate 13 and a button 14. The contact rod 12 is fixedly connected to the top of the limit strip 10, and the inclined plate 13 is slidably connected to the top of the mounting plate 9. The inclined plate 13 is squeezed and fitted with the contact rod 12, and the button 14 is fixedly connected to the top of the inclined plate 13.

[0028] When workers need to carry out highway construction at night, they can first place multiple protective devices at the edge of the construction area, and then pull the sliding rod 4 upward to a suitable height as needed, and turn the lighting lamp 5 so that the lighting lamp 5 illuminates the construction area, then pull the card strip 8 to the left and pull out the reflective strip 7, the rotating rod 6 will rotate immediately, and the torsion spring 61 will also deform immediately. Then the worker can continue to pull the card strip 8 and move the card strip 8 in the direction close to the mounting plate 9 on the other fixed frame 1. The card strip 8 continues to move and will first contact and squeeze the front and rear limit strips 10 on the other fixed frame 1, so that the front and rear limit strips 10 move back to each other first, and the elastic rope 11 is stretched immediately. When the card strip 8 continues to move and separates from the front and rear limit strips 10, the front and rear limit strips 10 will move toward each other under the action of the elastic rope 11 and clamp the card strip 8. At this time, the reflective strip 7 is connected between the two fixed frames 1 to warn the driver, and then the card strip 8 on the other fixed frame 1 is When the card strip 8 is pulled out and circulated, the entire construction area can be enclosed to remind the driver of the specific scope of the highway construction at night, so as to prevent the driver from mistakenly passing through the construction area and causing danger due to the lack of obvious warning range. After the construction is completed, the button 14 can be pressed downward, so that the inclined plate 13 moves downward and squeezes the front and rear contact rods 12, so that the front and rear contact rods 12 and the limit strip 10 all move back to each other and separate from the card strip 8, and the elastic rope 11 is stretched immediately. At this time, the rotating rod 6 will rotate in the opposite direction and reset under the action of the torsion spring 61, and the card strip 8 and the reflective strip 7 will be recovered and reset, so that the staff can quickly unlock the card strip 8 and roll up the reflective strip 7, and then the button 14 can be released. At this time, the front and rear contact rods 12 and the limit strip 10 will move toward each other and return to the initial state under the action of the elastic rope 11. The reset of the front and rear contact rods 12 will squeeze the button 14 and cause the button 14 to move upward and reset, and finally the protective device can be recovered.

[0030] like Figure 6 As shown, the alarm 15 has an internal ultrasonic sensor, and the ultrasonic sensor is electrically connected to the alarm 15.

[0031] During construction, if the ultrasonic sensor inside the alarm 15 detects that a vehicle or pedestrian is approaching, the alarm 15 will sound an alarm through the controller to warn the driver or pedestrian. In addition, when there is no construction during the day, the articulated solar panel 161 can be flipped upward and opened to absorb solar energy for storage through the fixed solar panel 16 and the articulated solar panel 161, and to power the alarm 15 and the lighting lamp 5 that are needed at night. During construction at night, the articulated solar panel 161 can be rotated in the opposite direction and reset to prevent dust or debris generated by the construction from falling on the fixed solar panel 16 and the articulated solar panel 161, thereby affecting the power generation effect.
