Self-power-generation heating pipeline

The utility model relates to a self-generating heating pipeline, which belongs to the field of drainage pipeline anti-freezing equipment and comprises a water pipe, a control unit, a rectifier and a battery pack, a heating sleeve for heating the water pipe is sleeved on the outer side of the water pipe, and a generator for converting flowing kinetic energy of water in the water pipe into electric energy is further mounted on the water pipe. The generator is electrically connected to the rectifier and the battery pack and stores electric energy in the battery pack, and the battery pack is electrically connected to the heating jacket and provides electric energy for the heating jacket. Kinetic energy generated when water in the drainage pipe flows at normal air temperature can be converted into electric energy to be stored, and when the air temperature drops and the water on the drain outlet is blocked, the drainage pipe can be heated, so that the water can flow, and the situation that the energy consumption of
