The invention provides a segmented heating type multipoint thermocouple liquid level detector for conducting heat through heat conduction blocks. N pieces of heat conduction blocks are arranged in a pressure bearing casing pipe. (N-1) pieces of heat conduction blocks are heated by an armored heating cable provided with (N-1) segments of heating resistance wires; the lengths of the heating resistance wires are identical to the heights of the heat conduction blocks; a heated armored thermocouple is arranged on each of the (N-1) pieces of heated heat conduction blocks, and the measuring point of each heated armored thermocouple is located in the middle of each heat conduction block; one of the N pieces of heat conduction blocks is unheated, and one armored thermocouple is arranged on the unheated heat conduction block; the N pieces of heat conduction blocks are positioned by supporting plates and are clung to the inner wall of the pressure bearing casing pipe; and a liquid level is measured through the score of
