FIELD: road-signal equipment. ^ SUBSTANCE: device intends for marking axial line of road in form point chain of reflected white light during night-time as well as at rain and fog and for in-time warning of drivers on temperature drop at surface of road coating till negative meanings and arise of glaze onto moist surface of roads due to automatic autonomous change of white light to red one without usage of additional power sources. Transition lower than 0 degrees results in change of color of ray reflected from surface of signaling device. Device for signaling on glaze beginning has case 1 with windows 2, thread 14, cone 15, lug 17, internal cylinder 3 with white light W and red light R reflecting rings, centering bushing 4 of internal cylinder. Device also has hydraulic drive which has case in form of cylinder 5, power cylinder 7 with piston and rod 9, sealing 6, elastic vessel 8 of body 10 filled water, body 11 filled with low-freezing liquid, centering bushing of hydraulic drive 12 with con-shaped surface 15, thread plug 13 of spring 16.According o the other version, device for signaling on glaze beginning has case 1 with windows 2, thread 14, cone 15, lug 17, internal cylinder 3 with red-light and white-light W reflecting rings, centering bushing 4 of internal cylinder . Hydraulic drive has case in form of cylinder provided with thread for plug, power cylinder with piston and rod, thread plug sealing 25 with protrusion, elastic container, body filled with low-freezing liquid, water-filled container, centering bushing of hydraulic drive 12 with cone-shaped surface 15, thread plug 13 and spring 16. ^ EFFECT: autonomous operation; no necessity in application of additional power supplies. ^ 2 cl, 3 dwg |
