摘 要:北方地区冬季温室屋顶积雪一方面对温室的透光性、保温性造成很大的影响,导致了大量能源的浪费,影响了喜阳植物的生长,另一方面影响温室的总体强度和刚度。目前应用在温室屋顶除雪比较常用的方法是采用热水融雪管,但是投资和运行费均比较高,为了解决这一问题,设计并制造了整体输送式温室屋顶除雪装置,试验效果良好,为今后温室屋顶除雪提供了一种有效、低运行费的方案。Snow on the greenhouse roof has a great effect on light transparence and heat loss. It brings bad effect on plant growing and also affects greenhouse structure strength. Using hot water pipe system is a normal way for cleaning snow on the roof, but its investment and operation cost are very high. In order to solve the problem, a kind of equipment for cleaning snow on the greenhouse roof was designed and experiments were done to test its performance. The result is satisfactory. An efficient and cost saving way for cleaning snow on the greenhouse roof was put foward.
