  • Patent number: 7798432
    Abstract: The present invention provides a deicing device for spraying anti-icing agents over a transport surface, such as paved road or bridge, to protect the transport surface from snow deposition and ice formation. The deicing device that is surface mounted to the transport surface has a pavement sensor to determine when the deicing device is turned on and off to spray the anti-icing agents. The deicing device comprises a supporting housing, a spray puck having a plurality of nozzles and jet channels connected to the nozzles for spraying anti-icing agents, a lock ring to immobilize the spray buck within the supporting housing, and an O-ring for sealing the anti-icing agents from leaking. The spray puck can be rotated within the supporting housing to change a spray direction. The jet channels have round corners, such as parabolic shape cross-section, to prevent from collection of dirt or debris.
