Technical Field
The invention relates to the technical field of hydraulic engineering, in particular to a gravity-flow type layered water taking system with a pipeline.
Background
At present, the existing layered water taking devices are mainly classified into the following four categories: the hydraulic automatic water taking device, the machine control tower type multilayer water taking device, the machine control inclined horizontal pipe multilayer water taking device and the machine control multi-section cylinder sleeve overlapped water taking device mainly achieve the aim of water taking of the reservoir in a layered mode by arranging a water intake room built with a dam body in the reservoir and arranging water taking ports on the side of the reservoir in the water intake room in a layered mode.
But there are major disadvantages:
civil engineering and reinforced concrete engineering for building the water intake tower are large, the construction period is long, the construction cost is high, and the technical defects of unstable engineering structure and poor controllability exist; the investment on the gate and the opening and closing equipment is high, and the early engineering investment is increased; when the water supply device operates, the gates in different water taking runners need to be opened under different water levels, and the operation and maintenance cost is higher in the later period of long-term operation of the hoist; in addition, in the current stage, the water taking temperature of the layered water taking is single in the operation process, surface water can be selected and taken only according to the variation of the water level of the reservoir, and the water temperature of the surface water is limited by local climate; finally, the operation management of layered water taking at the present stage is complex, the on-off equipment needs to be overhauled, maintained and maintained frequently, and the reservoir can only be emptied when the pipeline fails in the operation period, so that the waste of water resources and the discontinuity of reservoir operation are caused.
Disclosure of Invention
The invention aims to provide a gravity-flow type layered water taking structure for a pipeline, which has the characteristics of simple structure, convenient construction, good water taking effect, convenient operation and management, high safety and reliability, capability of taking water into consideration and emptying and lowering ecological flow, convenient maintenance of the device, adjustable water taking temperature, reduction of water resource waste, guarantee of long-term interest after the reservoir is built and the like.
The invention is realized by the following technical scheme:
the invention discloses a gravity-flow pipeline layered water taking system which comprises a dam body, wherein a plurality of dam body water taking ports are arranged at the inner upstream side of the dam body, and a plurality of water taking pipelines are embedded in the dam body; arranging a plurality of manholes on the inner downstream side of the dam body, and arranging service butterfly valves in the manholes; the aforementioned intake pipe is connected to the downstream-side confluence pipe, and a working valve is disposed between the aforementioned intake pipe and the confluence pipe.
Furthermore, the dam body water intake is at least three, namely an upper layer water intake, a middle layer water intake and a lower layer water intake, wherein the height difference between the bottom elevations of the upper layer water intake and the middle layer water intake is not less than 15m, the water intakes are arranged in a step shape, and the front end of the dam body water intake is provided with a trash rack.
Furthermore, the front end of any dam body water intake is positioned in the reservoir area, the rear end is positioned in the dam body, and the water intakes of the upper, middle and lower layers of the dam body are all lower than the water storage level and higher than the silt elevation of the reservoir.
Furthermore, the front end of any water intake pipeline is communicated with the tail end of a water intake of the dam body, the other end of the water intake pipeline is communicated with the downstream side of the dam body along the water flow direction, a maintenance hole and a maintenance butterfly valve are arranged, and the water intake pipeline is arranged along a downstream dam slope and is communicated with a downstream converging pipeline of the dam body.
The invention has the beneficial effects that:
firstly, the invention does not need to construct a water taking tower and a water taking tunnel, thereby reducing the construction work amount of the water taking tower and the water taking tunnel and the pouring amount of reinforced concrete. And the fixed pipeline layered water taking device is constructed together with the dam, so that the independent arrangement of the construction period is not needed, the external interference is small, and the construction period of the hydraulic engineering is shortened. Not only saves the construction investment of hydraulic engineering, but also can realize the early investment and operation of the reservoir.
And secondly, the water intake ports of the invention do not need to be provided with gates, and simultaneously, the corresponding operating cost of gate opening and closing equipment is reduced. The water intake pipeline is controlled by the valve to be opened or closed under the condition of reservoir water level amplitude variation through monitoring of the water level system, so that the requirement of layered water intake is met through the water intake ports in the set different height intervals, and only one set of control system is needed to be arranged in the gate valve chamber, so that the equipment investment cost and the later operation cost are saved.
And thirdly, when the water taking device runs, each water taking pipeline takes water relatively independently, and surface water taking under different water levels can be achieved by opening and closing the working valve according to different water taking water levels. And the water supply method adopts a combined water taking mode of surface water plus middle-layer water or surface water plus middle-layer water and the like according to different requirements of water supply requirements of specific objects on water temperature, so that more diversified water temperatures are enriched compared with the current single surface water temperature, water supply objects under different conditions and different requirements of different environments are met, and the water supply temperature required by production life and ecological environment can be closer.
Finally, the invention has higher reliability on continuous operation, if single-layer or multi-layer water taking is out of order during the operation, the accident valve of the corresponding pipeline can be closed immediately, and the water delivery task can still be provided continuously on the premise of meeting the water level. And if the water intake pipeline of the middle and upper layers needs to be overhauled, the reservoir does not need to be emptied, and only when the water level drops to the water intake in the dry period, the accident valve of the pipeline needing to be overhauled is opened, the existing water intake pipeline is temporarily closed, and the water in the pipeline can be emptied to the downstream, so that the conditions that the downstream water supply can be ensured and the dry construction can be created without emptying the reservoir are achieved, the waste of water resources is reduced, and the long-term prosperity of the reservoir after the construction is ensured.
