A screw type continuous filtering device for a waste water source, a surface water source and a heat pump water source is a water source continuous filtering device needed by the heat or the refrigeration of a water source which contains contaminants and is extracted from a heat pump system, and the water source continuous filtering device is designed for solving the problem of the obstruction of a heat interchanger. The water containing solid contaminants and fibers enters an inhalant region (5) through a water inlet (1) and is delivered to a filtering region (8) by a screw diversion rod (10) rotated by a speed changing electric motor (11), a bristle brush (12) embedded into the screw diversion rod (10) continuously clears the solid contaminants and the fibers attached to a cylinder-shaped filtering net (9), and the water reaches a water outlet (2) through the cylinder-shaped filtering net (9) and then is delivered to the heat interchanger. Furthermore, the solid contaminants and the fibers are continuously
