PROBLEM TO BE SOLVED: To provide a liquid antifreezing agent feeding device that may be manufactured readily at a low cost, eliminates a need for embedding into a road surface, offers significant towing and dispersion effects by spraying a small amount of a liquid antifreezing agent, and may be installed only during winter if chosen to do so.SOLUTION: A liquid antifreezing agent feeding device includes: a storage part 1 for storing a liquid antifreezing agent; a sensor part for detecting various indicators on outside conditions; a control part 3 that controls a feeding time and a fed amount in response to a detection result by the sensor part; an injection nozzle 4 disposed on a road side for feeding the liquid antifreezing agent onto a road surface; a liquid feeding part 2 that feeds the liquid antifreezing agent to the injection nozzle 4 from the storage part 1; and a power source for driving the liquid feeding part 2, the sensor part, and the control part 3. The liquid feeding part 2 includes a pump that is intermittent pumping means, and an injection motor-operated valve that opens/closes pipeline, and the injection nozzle 4 includes a universal joint for adjusting a direction of injection.SELECTED DRAWING: Figure 1 |
