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.
