The utility model discloses a heat supply pipeline protection device which comprises a protection module and a temperature sensor. Wherein the protection module comprises two shells, the edges of the two shells are fixedly connected through bolts respectively, corresponding heat preservation covers are arranged in the two shells respectively, and the edges of the two heat preservation covers are attached to each other respectively. The pipeline is wrapped by the protection module, the electrodes at the two ends of the two electric heating wires are electrically connected with the external power source respectively, the two electric heating wires are electrically connected with the temperature sensor respectively, and when the temperature sensor senses that the temperature of the pipeline is low, a signal is fed back to the external controller to control the external power source to be started; the two electric heating wires are heated, the temperature in the arc-shaped cavity is increased, and the temperature
