摘要
气象观测场中风向、风速仪支架杆一般为固定铁管,并用拉丝稳固;由于拉丝影响,使观测场外观形象显得杂乱不美观;又由于风杆是固定的,对风向、风速仪维修及风杆上漆维护不方便。基于此问题,设计出一种方便竖立又容易放倒且无拉丝稳固的风杆,这种风杆如何制作及部件制作的合理分析计算是其关键环节。
Wind direction and anemometer support rod is generallyiron pipe fixed by wire drawing in Meteorological obser- vation field, since several root drawing make observation field is disordered and not beautiful appearance, and because the wind rod is fixed, it is not convenient to repair and maintenance the wind direction and anemometer, and japanning the rod. Based on this problem, we designed a rod easy to set up and down without drawing, so how to make and reasonable analysis and calculation of parts production are the main content of this article.
