Planar trash rack for water conservancy canal
The invention relates to the technical field of water conservancy projects, and discloses a planar trash rack for a water conservancy canal. The planar trash rack comprises an upper frame, the bottom end of the upper frame is fixedly connected with a rack blade inner shaft, the top end and the bottom end of the rack blade inner shaft are both hollow air pipes, the inner ends of the hollow air pipes are provided with air vents, a rack blade outer shaft is movably connected to the outer side of the rack blade inner shaft, rack blades are fixedly connected to the front face and the back face of the rack blade outer shaft, a lower frame is fixedly connected to the bottom end of the rack blade inner shaft, a lower steering blade moving groove is fixedly connected to the bottom end of the interior of the rack blade outer shaft, upper steering blades are movably connected to the top end of the lower steering blade moving groove, and the other ends of the upper steering blades are fixedly connected with the upper frame. According to the planar trash rack, compressed air is introduced underwater to drive water with relatively high temperature in a underwater layer to a water surface, so that freezing of the trash rack due to low temperature is avoided, and the defects of influence on trash holding effect, high power consumption and the like in traditional anti-freezing measures are overcome.
本发明涉及水利工程技术领域，且公开了一种水利水渠用平面型拦污栅，包括上框架，所述上框架的底端固定连接有栅叶内轴，所述栅叶内轴的顶端和底端均为中空气管，且在中空气管的里端开设有通气口，所述栅叶内轴的外侧活动连接有栅叶外轴，所述栅叶外轴的正面和背面均固定连接有栅叶，所述栅叶内轴的底端固定连接有下框架，所述栅叶外轴内部的底端固定连接有下转向叶移动槽，所述下转向叶移动槽的顶端活动连接有上转向叶，所述上转向叶的另一端与上框架固定连接。本发明通过将压缩气体通入水下，带动水下层温度较高的水至水面，从而避免拦污栅因温度低而结冰，避免了传统防冻措施中影响拦污效果以及耗电量大等缺点。
