To provide a method to suppress snow adherence to incident or outgoing parts of a railroad crossing safety device.SOLUTION: A railroad crossing safety device 1 has a snow protection hood 12 in front of a main body 11. The snow protection hood 12 is arranged in front of the main body 11 and has an upper surface plate 121 covering an upper side of incident parts 111a and 111b which receive incident electromagnetic waves. Also, the hood 12 has a front plate 123 in the front side of the hood. The front plate 123 has two apertures, of which upper one is shaped to be a through hole in the upper part of the front plate 123. In the lower surface side of the upper surface plate 121, a wind direction plate 125 is arranged which changes the flow of a wind flowing into the inside of the snow protection hood 12 through either of the apertures from the front. Snow entering the inside of the hood 12 along with the wind travels downward and exits out of the hood 12 without adhering to the incident parts 111a or 111b.SELECTED DRAWING: Figure 1
【課題】踏切保安装置の入射部又は出射部に対する雪の付着を抑止する。【解決手段】踏切保安装置1は本体11の前面に防雪フード12を有する。防雪フード12は、本体11の前面に配置され、入射する電磁波を受波する入射部111a及び入射部111bの上方を覆う上面板121を有する。また、防雪フード12は、前方側に前面板123を有する。前面板123は2つの開口部を有し、上側の開口部は前面板123の上辺側に抜けた形状となっている。上面板121の下面側には、前方からいずれかの開口部を通って防雪フード12内へと流れ込む風の流れを変える風向板125が設けられている。この風と共に、防雪フード12内へと侵入した雪は下方へ向かい、入射部111a又は入射部111bに付着することなく防雪フード12の外部に出る。【選択図】図1
