Induction heater

Abstract

The invention provides an induction heater which comprises a sealed box body formed by magnetic steel plates and a disc type induction coil on a longitudinal side panel in the sealed box body. The sealed box body can float in the water of a water reservoir. The side panel of the sealed box body is parallel to and close to a pumped-storage reservoir artificial panel or parallel to and close to a common reservoir steel gate panel, before freezing, the side panel is always in a frozen ice layer with the change of the water level in the water reservoir, when intermidiate-frequency or high-frequency current is applied to the disc type induction coil, the sealed box body longitudinal side panel generates eddy current heating, the heated sealed box body longitudinal side panel directly acts heat to the ice layer in contact to melt the ice layer, an air gap is formed after the melting of the ice layer, and at that time the induction heater can stop heating to save energy. According to the induction heater, the problem of the frozen pumped-storage reservoir artificial panel is solved, and the problems of difficult opening of a common water reservoir steel gate due to freezing and the squezing deformation of the steel gate by frozen ice are solved at the same time.

Description

technical field [0001] The technical field that the present invention relates to has induction heating, particularly relates to a kind of sealing box made of magnetically conductive metal plate or magnetically conductive steel plate that will be frozen on the anti-seepage water panel artificially manufactured by pumped storage reservoir during induction heating Induction heaters that melt ice as well as ice that freezes in front of general reservoir locks. Background technique [0002] In the anti-freezing mode of the anti-seepage water panel artificially manufactured in the existing pumped storage reservoir, no method has been found to solve the problem of freezing of the artificially manufactured anti-seepage water panel of the pumped storage reservoir. Also have, what adopted in existing general reservoir steel gate panel anti-freezing mode is resistance heater. According to the patent report of CN201310378627, a kind of gate anti-icing device, the heat generated by the ...

Problems solved by technology

In the ice melting method of resistance heating, the heat energy is indirectly melted in the form of conduction, and the time for heat energy to be transmitted to the front panel of the steel gate is relatively slow, resulting in a slow melting speed of the ice layer, and the resistance element is also prone to aging, and it is installed in the reservoir dam Resistance heating elements on steel gates are difficult to repair, replace
