Abstract
The utility model relates to snow removing systems, particularly to a multi-span greenhouse snow removing system. The multi-span greenhouse snow removing system comprises main cables, electromagnetic heating strips, protective controllers, gutters and an electric cabinet. The electromagnetic heating strips are arranged inside the gutters and used for heating the gutters to melt snow; the electric cabinet is connected with the electromagnetic heating strips through the main cables to supply power to the electromagnetic heating strips and to drive the electromagnetic heating strips to work. For enlarging the snow melting area, the electromagnetic heating strips are sleeved by PE (polyethylene) pipes and increase the temperature of the positions where the electromagnetic heating strips are arranged, so that snow in the gutters can melt rapidly and further snow in other positions can drop down and melt due to loss of attachment points, molten snow water can flow down along a drainage pipe, and the aim of safe snow removal can be achieved. The multi-span greenhouse snow removing system has the advantages of supporting heat preservation of the gutters and being low in operating cost, capable of achieving automatic control, easy to install and maintain, safe in usage and the like.
