The present invention relates to a hazardous situation warning device used on a road. More specifically, the device generates a warning sound when a drowsy, drunken, or inexperienced vehicle driver collides to a warning cone lamp arranged on a road construction site and enters the road construction site where is under construction, in order to evacuate workers in the road construction site. An insertion groove is formed on the lower floor of a cylindrical support in an upward direction. A transmitter base, which includes a negative sensor embedded in the center and protruding support units on both ends, is embedded in the center of the upper surface of the support. A transmitter having a transmission frequency generator embedded therein, a positive sensor embedded in the lower surface, and support grooves on both ends of the lower surface is mounted on top of the transmitter base to support the support units on the support grooves. A receiver includes a reception unit connected to a battery and a warning speaker. When the warning cone, which is installed in back of the road construction site while having a distance of 30-50 m of the construction site, receives an impact from a vehicle entering the road construction site, the transmitter is separated from the transmitter base of the support mounted on the warning cone in order to enable the receiver installed on the road construction site to receive a signal generated by the transmitter frequency generator, thereby generating a warning sound to be output through the warning speaker. The warning sound, which is generated in the road construction site as the transmitter is separated by the impact delivered from the vehicle entering the road construction site to the warning cone, enables workers in the road construction site to sense danger and escape as the vehicle enters the road construction site, thereby ensuring the safety of the workers. |
