Abstract
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.
