- 摘要:
- SR型人工降雨装置是一种多喷头、多单元组合式的间歇降雨装置.选用目前国内外较理想的喷头，在喷头处辅以可改变喷头降水方式的机械传动装置，以间歇方式降雨来满足其降雨强度，雨滴直径大小及其分布与自然降雨相似.每个单元的有效降雨面积为2m×5m；如果4个单元组合成，其长度可增加4倍，有效降雨面积即2m×20m.装置采用轻型铝合金材料制成，结构简单，易于安装拆卸，适用于野外工作.
- Abstract:
- The new SR style artificial rainfall simulator was an intermittent rain device composed by multiple nozzles and units.The nozzles were more ideally selected from home and abroad,which supplemented the mechanical transmission equipment to change the nozzles and the rainfall intensity could be changed and satisfied by the intermittent rainfall pattern.The raindrop diameter and distribution was similar with the natural rainfall.The affective rainfall area was 2m×5m for every rainfall unit,if 4 rainfall units were composed,the length could be increased 4 times,and the effecrive rainfall area was 2m×20m.The equipment was constructed by aluminum alloy material,and the simple structure could be easy to install and dismantle,and suitable to work in field.
