Abstract

A modular heating section for removing or preventing the formation of ice on the walls of navigation locks, loading docks, ferry slips, or the like. Ice formation on the walls of navigation locks is compressed by successive vessels to the extent that larger vessels are unable to enter the locks. To avoid this happening, ice is chipped from the walls of the locks, which is time-consuming. As well, chipping of the ice results in damage to the concrete walls which must then be repaired. To overcome this problem, the present invention proposes the use of a modular heating section comprising a rigid panel having means for securing the section to a navigation lock wall, loading dock, or the like at a location where ice formation occurs, the panel being made from a heat conducting material. The panel includes heater means situated therein, the heater means adapted to distribute heat throughout the modular heating sections. Connector means are operatively connected with the heater means, said connector means adapted to connect the heater means to an energy supply, with individual or multiple control of heat to the panels, depending upon the area of surface to be heated. A rear surface of the modular heating section is provided with a layer of heat insulating material, whereby heat transfer through the rear surface of the panel to the lock wall, loading dock, or the like is limited. The modular heating section is adapted to prevent the accumulation of ice on lock walls, loading docks, ferry slips, or the like by providing heat to an outer surface of the modular heating section by means of the heater means.

A modular heating section for use in association with navigation lock walls, loading docks, ferry slips, or the like, said modular heating section comprising:

a rigid panel having means for securing the section to a navigation lock wall, loading dock, or the like, at a location where ice formation occurs, the panel made from a heat conducting mortar mix;
the panel including heater means situated therein, the heater means adapted to distribute heat throughout the modular heating sections, the mortar mix providing a suitable bonding to the heater means while providing increased compressive strength to the modular heating section,
connector means operatively connected with the heater means, said connector means adapted to connect the heater means to an energy supply;
a rear surface of the modular heating section provided with a layer of heat insulating material, whereby heat transfer through the rear surface of the panel to the lock wall, loading dock, or the like is limited, the layer of heat insulating material provided on both sides thereof with a bonding layer in order to increase adhesion of the layer of heat insulating material to the modular heating section, said modular heating section adapted to prevent the accumulation of ice on lock walls, loading docks, ferry slips, or the like by providing heat to an outer surface of the modular heating section by means of the heater means, the outer surface of the section being provided with a smooth resistant surface to limit adherence of ice thereto, and to reduce wear thereof, said section including structural steel within the section intermediate the outer surface and the heater means, the structural steel adapted to strengthen the section and distribute heat generated by the heater means across the outer surface of the section, the modular heating section further including screening of conducting material intermediate the heater means and outer surface thereof, the heat conducting screening adapted to distribute heat to the outer surface of the section.
