Dirt cleaning device suitable for working condition of narrow trash cleaning orifice of trash rack

ZHANG XIANHAI / LIU YANG

The invention discloses a trash cleaning device suitable for a narrow working condition of a trash cleaning orifice of a trash rack, the trash cleaning device comprises a trash cleaning unit, a moving unit and a winch unit, the trash cleaning unit comprises a movable form relieved tooth and a fixed form relieved tooth, a first hydraulic rod is arranged on the upper portion of the movable form relieved tooth, and a fixed column is arranged at one end of the first hydraulic rod; second hydraulic rods are arranged on the side faces of the fixing columns, and rolling wheels are fixedly connected to one ends of the second hydraulic rods. The moving unit comprises a lead screw, a second fixing plate is arranged at the bottom of the lead screw, and a third hydraulic rod is arranged on one side of the second fixing plate; when the efficient trash remover is used for trash removal operation, a special grab bucket type trash remover grab bucket guide groove does not need to be additionally arranged, the situation that the width of a trash removal channel is not constant can be met, the efficient trash remover can play a role in an old hydropower station, and meanwhile the problem that dirt wound on the surface of a trash rack is difficult to remove is solved. The power generation loss of the hydropower stations is greatly reduced, and the power generation benefit is increased.

本发明公开了一种适用于拦污栅清污孔口狭窄工况的清污装置，包括，清污单元，移动单元，卷扬单元，所述清污单元包括活动铲齿和固定铲齿，所述活动铲齿上部设置有第一液压杆，且第一液压杆一端设置有固定柱，所述固定柱侧面设置有第二液压杆，且第二液压杆一端固定连接有滚轮；所述移动单元包括丝杆，所述丝杆底部设置有第二固定板，且第二固定板一侧设置有第三液压杆；所述卷扬单元包括卷扬机，通过本发明进行清污作业时，既不需要增设专门的抓斗式清污机抓斗导槽，还能满足清污通道宽度不恒定的状况，使高效清污机能在老水电站发挥作用，同时解决了拦污栅表面缠绕污物难以去除的问题，使这些水电站的发电损失大大减少，增加了发电效益。
