[0026] Please see Figure 1 This utility model provides a pollution-preventing tunnel safety reflective device, including a first reflective sheet 1, an iron sheet 2, a pollutant adsorption sheet 3, a second reflective sheet 4, a water-soluble adhesive layer 5, a third reflective sheet 6, a magnetic sheet 7, a base 8, and a fixing rod 9.

[0027] The first reflective sheet 1 is fixedly connected to the iron sheet 2, and the lower end of the iron sheet 2 is fixedly connected to the upper end of the pollutant adsorption sheet 3; the pollutant adsorption sheet 3 is used to adhere pollutants.

[0028] The second reflector 4 and the third reflector 6 are connected by a water-soluble adhesive layer 5. A magnet 7 is provided between the third reflector 6 and the base 8, and the magnet 7 is fixedly connected to the base 8. One end of the fixing rod 9 is fixedly connected to the base 8. The iron sheet 2 is attracted to one side of the second reflector 4 by the magnetic force of the magnet 7. The fixing rod 9 is used to fix the corresponding monitoring point.

[0029] In one embodiment of this utility model, a receiving groove 81 is provided on the base 8, and the magnet piece 7 is fixedly disposed in the receiving groove 81.

[0030] In one embodiment of this utility model, the third reflector 6 and the base 8 are bonded together with non-water-soluble adhesive.

[0031] In one embodiment of the present invention, the pollutant adsorption sheet 3 is coated with adhesive for adhering pollutants.

[0032] In one embodiment of this utility model, the size of the magnet piece 7 is 1cm×1cm×0.5cm.

[0033] In one embodiment of this utility model, the magnet sheet 7 is a neodymium magnet or a ferrite magnet.

[0034] In one embodiment of this utility model, the iron sheet 2 has dimensions of 4cm × 4cm × 0.2cm.

[0035] In one embodiment of this utility model, the weight of the iron sheet 2 is 21-25 grams.

[0036] In one embodiment of this utility model, the surface dimensions of the first reflector 1, the second reflector 4 and the third reflector 6 are all 4cm×4cm, and the center points of the first reflector 1, the second reflector 4 and the third reflector 6 are collinear.

[0037] According to the applicant's experiments, the magnet 7 is a ferrite magnet with a size of 1cm×1cm×0.5cm and an adsorption force of 50g to 150g; the iron sheet is 4cm×4cm×0.2cm and weighs 25.2g; ignoring the weight of the pollutant adsorption sheet 3 and the first reflector 1, the first reflector 1 will fall off when the amount of dust adsorbed on the adsorption sheet 3 and the first reflector 1 is greater than 25g.

[0038] In use, this utility model is fixedly connected to the corresponding monitoring point by one end of the fixing rod 9. As the usage time increases, the pollutants adsorbed on the first reflector 1 and the pollutant adsorption sheet 3 become too heavy for the magnetic force of the magnet sheet 7 to adsorb the iron sheet 2, and the first reflector 1 falls off along with the iron sheet 2; the pollution prevention tunnel safety reflector device exposes the second reflector 4, which the user can use to continue monitoring; when the monitoring personnel find that there are too many pollutants on the second reflector 4, making the second reflector 4 unusable, the water-soluble adhesive layer 5 between the second reflector 4 and the third reflector 6 can be flushed with water, thereby causing the second reflector 4 to fall off, and the user can use the third reflector 6 to continue monitoring, thus ensuring the continuity of monitoring data.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
