Water taking system for shallow water river in water-depleted mountainous area
The invention discloses a water taking system for a shallow water river in a water-depleted mountainous area. The system involves an overflow weir, a water taking chamber and a radiation well, whereina spillway grid is arranged at an inlet of the water taking chamber, a floating mushroom head automatic water taking device and an on-line turbidity meter are arranged in the water taking chamber, and a submersible pump is arranged in the radiation well. When flooding does not occur, the overflow weir lifts the water level of the shallow water river, river water flows into the water taking chamber through the spillway grid, and then enters a water conveying pipe from the floating mushroom head automatic water taking device to flow to the radiation well, and finally, the submersible pump conveys the river water to a subsequent water purifying structure; a drought period relies on joint recharge of the above mentioned surface water recharge mode and the seepage of the radiation well; when the on-line turbidity meter in the water taking chamber during a flood period is displayed higher than 5 NTU, the on-line turbidity meter feeds back a signal to a self-control system, an electric butterfly valve mounted on the water conveying pipe is closed, and the radiation well supplies water through the self-seepage; according to the water taking system, the water supply amount of the shallow water river in the water-depleted mountainous area can be ensured, the water quality is reliable, the service life of the water taking system is prolonged, and the water taking cost is reduced.
本发明公开了一种贫水型山区浅水河流取水系统，该系统包括溢流堰、取水室和辐射井；其中，取水室入口处设溢洪格栅，取水室内设有漂浮蘑菇头自动取水装置和在线浊度仪，辐射井内设潜水泵。未发洪水时，溢流堰将浅水河流水位抬高，河水通过溢洪格栅流入取水室，再从漂浮蘑菇头自动取水装置进入输水管流至辐射井，最终潜水泵将河水输送至后续的净水构筑物中；枯水期依靠上述地表水补给方式和辐射井的渗流共同补给；洪水期取水室内的在线浊度仪显示高于5NTU时，在线浊度仪将信号反馈给自控系统，安装在输水管上的电动蝶阀关闭，辐射井通过自身渗流供水。本发明可保证贫水型山区浅水河流供水量、水质可靠，延长取水系统的使用寿命，降低取水成本。
