Problems solved by technology

Due to the climatic conditions of high evaporation and low rainfall in Northwest China, crops have the characteristics of large water demand and long irrigation cycle. The water supply and water demand of the pumping station irrigation system often do not match. It is greater than the amount of water used for agricultural irrigation and urban water supply, resulting in waste of water. In the dry season, the amount of water pumped by the pump station is not enough for agricultural irrigation and urban water supply. Creates waste and, therefore, an imbalance between the pumping station's pumping capacity and the actual water demand

Embodiment 1

[0016] Embodiment 1: A kind of cascade pumping station storage tank system based on water volume balance, such as figure 1 As shown, it includes two parallel water-lifting pipelines and cascade pumping stations 3 arranged at multi-level intervals. The two water-lifting pipelines pass through the cascade pumping stations 3 at all levels to form two parallel water-lifting lines, and the water is transported from the low water level through the The cascade pumping stations at all levels are pumped to the highest water level. The two water-lifting pipelines are the first water-lifting pipeline 1 and the second water-lifting pipeline 2 respectively. The first water-lifting pipeline 1 and the second water-lifting pipeline 2 are respectively equipped with control water-lifting pipes The opening and closing of the water supply valve, through the water supply valve controls the opening and closing of the corresponding water lifting pipeline, the first water lifting pipeline 1 and the se...

Embodiment 2

[0021]Embodiment 2: A cascaded pumping station adjustment and storage tank system based on water volume balance in this embodiment will be described with a different point center from that in Embodiment 1.

[0022] Such as figure 2 As shown, the water outlet of the storage tank is connected to a plurality of farmlands through a plurality of tributaries respectively, and the open channel is respectively connected to a plurality of farmlands through a plurality of tributaries. Taking No. 3 farmland 53 as an example, No. 3 farmland 53 is connected to The water outlet of the No. 1 storage tank 51 is connected, and the No. 3 farmland 53 is connected with the No. 1 open channel through the tributary open channel 8 at the same time, and the capacity of the No. 1 storage tank is V 1 , the amount of water required for the irrigation period of No. 1 farmland 51 and No. 3 farmland 53 is W 1 , W 3 , the flows of No. 1 open channel 61 and branch pipe 7 are respectively q 1 and q 3 , t...

Abstract

The invention relates to the technical fields of agricultural irrigation and urban water supply, in particular to a cascade pumping station regulation and storage tank system based on water volume balance, which includes two parallel water-lifting pipelines and cascade pumping stations set at multi-level intervals, and two water-lifting pipelines Two parallel water-lifting lines are formed through the cascade pumping stations at all levels. Water supply valves for controlling the opening and closing of the water-lifting pipelines are respectively installed on the two water-lifting pipelines. At least one of the water-lifting pipelines is opened, and the water-lifting pipeline passes through The open channel is connected to the farmland to provide the first irrigation waterway. There is also a storage tank between two adjacent cascade pumping stations. 2. Irrigation waterway. The system is supplied by two water supply lines. The amount of water can be adjusted according to the actual situation, and the adjustment and storage pools are set between the pumping stations at all levels. During the dry season, the agricultural irrigation water can be replenished through the adjustment and storage pools.

Description

technical field [0001] The invention relates to the technical fields of agricultural irrigation and urban water supply, in particular to a cascade pumping station regulation and storage pool system based on water volume balance. Background technique [0002] The cascade pumping station water delivery system consists of pumping stations (pumps, motors, other auxiliary devices, etc.), water outlets, channels and other equipment. The rational allocation of water resources is realized through pumping stations and pipelines. [0003] At present, cascade pumping stations have been widely used in agricultural irrigation, urban water supply, etc., and the role of cascade pumping stations in the arid areas of Northwest China is particularly important. Due to the climatic conditions of high evaporation and low rainfall in Northwest China, crops have the characteristics of large water demand and long irrigation cycle. The water supply and water demand of the pumping station irrigation ...
