A structure for examining safety of a drainage facility having a median strip is provided to allow a supervisor to judge whether a water channel is clogged by foreign substances by checking a warning plate. A structure for examining safety of a drainage facility having a median strip comprises a first and a second floater, a case, a rotary block, a damping unit, a first and a second connecting bar(100,110), a warning plate(120), a spring, a connecting member, and a fixing unit. The rotary block is rotatably mounted in the case wherein a projection unit is formed at one side. The first and second connecting bars connect the first and second floaters with the rotary block. The warning plate is vertically and rotatably mounted at a supporting rod(41). The spring is connected with the warning plate and elastically supports the warning plate. The connecting member is mounted in the supporting rod and connected with the warning plate. The fixing unit fixes the connecting member to allow the warning plate to be rotated downward. The fixing unit is connected with the connecting member and is fixed or released by a projection unit when the rotary block rotates. The supervisor can judge whether foreign substances are stuck in a water channel or not by checking the warning plate. |
