FIG. 3 is a graph in which the temperatures of the mirror surface and its periphery are recorded for 24 hours in the above both cases, and the temperature of the mirror surface of the reflector (A) according to the present invention is the temperature of the mirror surface of the conventional product (D). Compared to, it shows temperatures above freezing from night to morning. This is because when the wind is present, the heat energy generated by the wind power generator 10 and the electric heater 7 and the heat energy of the outside air from the mirror surface of the reflecting mirror are taken in during the time of fine weather when the temperature rises, and the heat storage agent 5 stores heat in a synergistic manner. To be done. When the wind is stopped or at night when the temperature drops, the mirror surface is heated by the thermal energy stored in the heat storage agent 5. By condensing the heat storage agent 5 into a gel, the convection phenomenon can be eliminated and the utilization efficiency of the heat storage energy can be improved. In addition, the gelation of the heat storage agent can reduce the temperature difference between the upper and lower portions of the mirror surface. A thermostat 22 that operates between 20 ° C. and 30 ° C. is connected to the wiring between the wind power generator 10 and the electric heater 7, and the energization of the electric heater 7 is stopped at a set temperature or higher. FIG. 3 shows the results of the above comparison test, and the present invention shows that the road reflector has a very effective effect of preventing snow accretion and snow.

The effects of the present invention are listed below. I. Wind power generation energy is generated by a wind power generator in a place where commercial electricity is not received, and this can be used by energizing an electric heater and exchanging electricity and heat. It can also be effectively used in evacuated areas or mountains where there is no power source. . B. The wind power generator is only about one-thousandth of commercial power in terms of continuous electric power retention, and is an energy that has unstable fluctuations of strength. But it is also pollution-free energy. Therefore, by using the heat storage agent, it is possible to store and average the large fluctuation of the heat generation amount of the electric heater in the heat storage agent and use it. This has a great merit that the reflecting surface can be heated by the stored heat energy even when the wind energy decreases. C. Also, if the heat storage agent container and the heat storage agent are made of a transparent plastic light-transmitting structure that allows heat to propagate, the heat generated by the electric heater is transferred to the heat storage agent in the heat storage agent container in a heat transfer manner, absorbing heat while storing heat, and in clear weather. Occasionally, effective heat storage can be achieved by heating the reflecting surface with the solar energy that has passed through the light.
