New energy underground drainage pipeline heat preservation heating system in cold region

The invention provides a new energy underground drainage pipeline heat preservation heating system in a cold region. The system is divided into three parts. The system comprises a power supply system,a heat preservation heating system and a temperature monitoring system; and the safe and economical pipe burying depth is calculated according to the local climate characteristics, the soil characteristics and the pipe heat preservation heating effect. The underground drainage pipeline heat preservation heating system can effectively prevent the problems that pipelines are blocked and frost-cracked in winter, liquid in the pipelines leaks and pollutes soil and the like; the temperature of fluid in the pipeline rises, the activity of microorganisms in sewage is improved, and fossil energy consumption is reduced; an operator can conveniently find a fault position in time, and maintenance is convenient; and the more reasonable pipe burying depth is recalculated, and the safety and economy ofpipeline operation are im
