Lift adjustment pressure reduction means

The utility model provides a lift adjustment pressure reduction means for fail safe nature is low in solving prior art, short, the problem with high costs inconveniently of adjusting of life. The utility model discloses an install a plurality of lift units on the dam foundation with row shape of face formula, the lift unit includes arc dam facing, control arc dam facing installation angle's control mechanism, be equipped with the basic groove that can hold control mechanism on the dam foundation. The advantage lies in: intensity is big, flood discharge capacity is strong, is adapted to scarcemanpower management's mountain area, safe controllability is high, and degree of automation is high, can reduce rivers and erode stable in structure, long service life to low reaches. 本实用新型提出了种升降调节降压装置，用以解决现有技术中安全可靠性低，使用寿命短、调节不便成本高的问题。本实用新型包括以排面形式安装于坝基上的若干升降单元，升降单元包括弧形坝面、控制弧形坝面安装角度的控制机构；坝基上设有得以容纳控制机构的基槽。优点在于：强度大、泄洪能力强，适应于缺乏人力管理的山区；安全可控度高，自动化程度高，能够减少水流对下游的冲刷，结构稳定，使用寿命长。
