Novel diversion trash rack for water intake of hydropower station
The invention discloses a novel diversion trash rack for a water intake of a hydropower station, relates to the field of water conservancy and hydropower engineering, and aims to reduce hydraulic loss after a water body flows through the water intake of the hydropower station and is preliminarily filtered. According to the technical scheme, the novel hydropower station water intake flow guide trash rack comprises an annular frame body and a plurality of flow guide plates fixedly installed on the frame body, the plate faces of the flow guide plates are parallel to one another and are perpendicular to the corresponding plane of the frame body, the flow guide plates are in a streamline shape, the outer contours of the flow guide plates on the first section are isosceles trapezoids, and the outer contours of the flow guide plates on the second section are isosceles trapezoids. The first section is parallel to the plate surface of the flow guide plate and passes through the center of the flow guide plate, the sides, corresponding to the upper bottom, of the two waists of the isosceles trapezoid are upstream faces, the side, corresponding to the lower bottom, of the isosceles trapezoid is a downstream face, diagonal planes are arranged between the upstream faces and the two plate surfaces, and chamfers are arranged on the plate surface of the flow guide plate and corner angles between the upstream faces and the diagonal planes respectively. The device is used for being arranged at the water intake of the hydropower station and plays a role in guiding and filtering water flow.
本发明公开了一种新型的水电站取水口导流拦污栅，涉及水利水电工程领域，目的在于减小水体流经水电站取水口进行初步过滤后的水力损失。本发明采用的技术方案是：一种新型的水电站取水口导流拦污栅，包括环状的框体和固定安装于框体的多块导流板，各块导流板的板面相互平行并与框体对应的平面垂直，导流板呈流线型，导流板在第一截面上的外轮廓为等腰梯形，第一截面与导流板的板面平行并经过导流板的中心，等腰梯形的两腰和上底对应的一侧为迎水面，等腰梯形的下底对应的一侧为背水面，迎水面与两个板面之间均设置斜切面，导流板的板面、迎水面和斜切面之间的棱角处分别设置倒角。本发明用于布置于水电站取水口，对水流起到导流和过滤的作用。
