Abstract

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.

Description

technical field

[0001] The invention belongs to the field of water supply and water source engineering, and particularly relates to a water-poor mountain shallow-water river water intake system. Background technique

[0002] For water-poor mountainous areas, the groundwater depth is shallow and the water permeability is weak, while the water quality of the rivers in mountainous areas is generally good, but the flow changes in flood and dry seasons, and the water volume is small or even stopped in dry seasons. The water level of the river is relatively shallow for many years. Even if the surface water of shallow rivers is blocked and stored by water retaining structures, it is generally difficult to ensure the water supply during the dry season, and the high turbidity and high sediment content in the flood season will increase the wear and tear of the raw water lift pump without treatment. Large follow-up water treatment structures operating load and water purification costs...

Embodiment Construction

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] like figure 1 As shown, the present invention provides a water-poor mountain shallow river water intake system. It is suitable for taking water from the banks of shallow rivers in poor-water mountainous areas where the depth of the groundwater table is shallow, the water permeability of the aquifer is weak, and the water volume of the river is small or even cut off during the dry season. The system consists of three parts: overflow ...
