Layered step-by-step clamping pier flow guide cover
The invention discloses a layered step-by-step clamping pier flow guide cover which comprises a bottom-layer flow guide sleeve and a plurality of standard flow guide sleeves, the outer contours of thebottom-layer flow guide sleeve and the standard flow guide sleeves are of streamline structures; the standard flow guide sleeves are arranged up and down; the bottom-layer flow guide sleeve is arranged on the lower side of the lowermost-layer standard flow guide sleeve; the upper side edge of the bottom-layer flow guide sleeve is detachably connected with the lower side edge of the lowest-layer standard flow guide sleeve through a plurality of first connecting bolts, and the adjacent side edges of every two adjacent standard flow guide sleeves are detachably connected through a plurality of first connecting bolts; the bottom-layer flow guide sleeve is formed by splicing a first V-shaped plate and a second V-shaped plate front and back; each standard flow guide sleeve is formed by splicinga third V-shaped plate and a fourth V-shaped plate front and back, double-beam truss structures are fixedly installed in the first V-shaped plate, the second V-shaped plate, the third V-shaped plateand the fourth V-shaped plate, and a locking device is installed on the front side of the double-beam truss structure in the fourth V-shaped plate on each layer. The flow guide sleeves are installed in a layered mode, operation is safe, water resistance is reduced, and water head losses are reduced.
一种分层逐级夹紧的桥墩导流罩，包括底层导流罩和若干个标准导流罩，底层导流罩和标准导流罩的外轮廓均为流线型结构，各个标准导流罩上下排列设置，底层导流罩设置在最下层标准导流罩的下侧，底层导流罩的上侧边和最下层标准导流罩的下侧边之间以及相邻两个标准导流罩的相邻侧边之间均通过若干根第一连接螺栓可拆卸连接，底层导流罩由第一V型板和第二V型板前后拼接组成，标准导流罩由第三V型板和第四V型板前后拼接组成，第一V型板内部、第二V型板内部、第三V型板内部和第四V型板内部均固定安装有双梁桁架结构，每层的第四V型板中的双梁桁架结构前侧部均安装有锁紧装置。本发明分层安装导流罩，操作安全，减少水阻，减少水头损失。
