The invention discloses a vehicle body device capable of avoiding light pollution, which comprises a vehicle body base and a top box, the top box is fixedly provided with an air inlet box on the windward side of a vehicle body, the vehicle body base and the air inlet box are jointly fixed with a windshield window, and the side wall and the bottom wall of the air inlet box penetrate through the box wall of the top box to be provided with an air inlet and an air outlet. A dust blocking net is fixedly arranged at the air inlet end, and a thermocouple is fixedly inserted into the top wall of the air inlet box. The device has the advantages that through the arrangement of the polaroid, the optical rotation plate and other structures, sunlight forms polarized light after passing through the polaroid, then the polarized light is rotated by 45 degrees through the optical rotation plate, and finally the polarized light is reflected by the reflecting mirror and irradiates the photomultiplier, so that an optical signal is converted into current; And the polarized light which is not irradiated on the photomultiplier tube passes through the optical rotation plate again and finally forms a 90-degree angle with the transmission direction of the polarized light, so that the light is prevented from being transmitted out, and the phenomenon of light pollution caused by sunlight reflection is avoided.
本发明公开了一种避免光污染的车体装置,包括车体底座与顶箱,所述顶箱在车体的迎风面固定设置有进风箱,所述车体底座与进风箱共同固定有挡风窗,所述进风箱的侧壁与底壁分别贯穿顶箱的箱壁开设有进风口与出风口,所述进风口端固定设置有阻灰网,所述进风箱的顶壁固定插设有热电偶。优点在于:本发明通过偏振片、旋光板等结构的设置,使得将太阳光线经过偏振片后形成偏振光再经过旋光板旋转45度,最后经过反射镜的反射照射在光电倍增管上使得将光信号转化为电流,未照射在光电倍增管上的偏振光将再次经过旋光板最终与偏振光的透射方向呈90度,避免光线透射出去,从而避免了由于太阳光线反射而造成光污染的现象。
