The invention belongs to the technical field of
liquid level measurement, and particularly relates to a liquid level measuring device capable of adjusting a measuring angle, the liquid level measuring device comprises a
handle, a fixed seat, a turntable and a
drill rod, one end of the
handle is connected with the fixed seat, the turntable is rotatably arranged in the fixed seat, and the
drill rod is arranged on one side of the turntable in an extending manner; a first through hole and a second through hole are formed in the side wall of the rotary disc in a penetrating mode, and a
fixed angle b degrees is formed between the first through hole and the second through hole. A third through hole and a fourth through hole are formed in the side wall of the fixing base in a penetrating mode, a fixing angle c degrees is formed between the third through hole and the fourth through hole, and b is smaller than c. When the first through hole and the third through hole directly face each other, the second through hole and the fourth through hole are staggered, and a bolt
assembly is inserted into the first through hole and the third through hole for fixation. When the second through hole and the fourth through hole are right opposite, the first through hole and the third through hole are staggered, and a plug pin
assembly is inserted into the second through hole and the fourth through hole for fixing. The device can conveniently adjust and measure the liquid level of
electrolyte and molten aluminum in the
electrolytic cell at a small angle according to the actual condition of the
electrolytic cell.
