The present application relates to the technical field of water replenishment in thermal power plants, and in particular to a monitoring device for water replenishment in a thermal power plant, which includes a boiler assembly, a monitoring assembly and a control assembly. According to the present application, the servo motor drives the fixing gear to move inside the fixing frame, and the sampling pump is fixed inside the fixing frame, so as to prevent the sampling pump from being displaced during operation and further prevent the resulted inaccurate sampling. Moreover, the first floating block and the second floating block are provided inside the boiler, the water level rises and then drives the first floating block to float upward when the water is replenished into the boiler, and the water slowly flows out of the first sleeve. As the water is increasingly replenished into the boiler, the second floating block increasingly floats upward above the first floating block, so that the external alarm gives an alarm to remind to stop water replenishment. Excess water is discharged to the exterior of the boiler through the connecting pipe and the floating pipe, so as to maintain the water level of the boiler at an expected height.
