【摘要】：为达到抑制干旱区平原水库水分蒸发的目的,采用PVC浮球为试验材料,通过室内、外试验观测并分析无配重浮球在不同风速下的运动情况,探究浮球产生不规则旋转和翻滚运动的原因,并采取增加配重的办法对此问题加以解决。通过对比不同配重的浮球在不同气象条件下的湿润率并对其在试验期内的蒸发抑制率进行评价,结果表明:负载配重后的浮球比无配重的浮球的防蒸发节水效果更加显著,其水面综合蒸发抑制率最大可提高24%。研究成果为干旱区平原水库的节水措施提供了新思路。
[Abstract]:In order to restrain the evaporation of water in plain reservoirs in arid area, PVC float ball was used as the experimental material, and the motion of the floating ball without counterweight under different wind speeds was observed and analyzed through indoor and external tests. This paper probes into the causes of irregular rotation and roll motion of float ball, and solves the problem by increasing counterweight. By comparing the wetting rate of float with different weights under different meteorological conditions and evaluating its evaporation inhibition rate during the experimental period, the results show that the anti-evaporation and water-saving effect of floating ball with load and weight is more remarkable than that without counterweight. The maximum inhibition rate of water surface evaporation can be increased by 24%. The research results provide a new idea for water saving measures of plain reservoirs in arid area.
