One-source two-pump stable water supply system and method applied to pasturing area

Abstract

The invention discloses a one-source two-pump stable water supply system and method applied to a pasturing area. The system comprises an energy supply unit, a control center, a shallow well, a reservoir, a first-stage water pumping device and a second-stage water pumping device. The energy supply unit is used for providing power electric energy; the shallow well is a well facility for exploiting shallow groundwater; the reservoir is used for supplying water to users, and the lowest water level of the reservoir is higher than the highest water level of the shallow well; the control center is used for controlling the first-stage water pumping device to pump water from the shallow water well to the reservoir and controlling the second-stage water pumping device to pump water from the reservoir to a user. The method comprises the steps that the electric energy provided by the energy supply unit is used for controlling the primary water pumping device to pump water from the shallow water well to the reservoir, and controlling the secondary water pumping device to pump water from the reservoir to a user. The contradiction between small underground water inflow and large instantaneous water demand of pasturing area water supply is solved, the production efficiency of animal husbandry is improved, and the labor capacity of the pasturing area is reduced.

Description

technical field [0001] The application belongs to the technical field of water supply in agricultural and pastoral areas, and in particular relates to a stable water supply system and method with one source and two pumps applied in pastoral areas. Background technique [0002] my country's pastoral areas are vast. Grassland animal husbandry is the foundation of economic development in pastoral areas and the main source of income for herdsmen. In most pastoral areas, animal husbandry is the only source of income for local people. At the same time, animal husbandry in pastoral areas is also an important source of meat supply in my country. [0003] The pastoral area is vast. Although most of the herdsmen’s residences are powered by the power grid, the water source is at least 3-5km away from home, and the distance is more than 10km. There is generally no power grid at the water source. Generally, herdsmen bring their own fuel water pumps. At the same time, water resources in ...

AI Technical Summary

Problems solved by technology

At the same time, water resources in pastoral areas are relatively scarce, and the water source mainly comes from shallow groundwater. The depth of the well is generally between 3-10m, and the water flow from the water source is small, and the water flow per hour is 1-2m. 3 , large water demand, 3-5m of water at a time 3 , if extracting 3-5m directly from the water source 3 Water, the herdsmen drain the limited amount of water in a short period of time when they fetch water, and they need to wait for the next water storage when they fetch water, which takes a long time and uses water very poorly

[0004] In view of the remoteness of pastoral areas, the lack of water sources, the lack of conventional energy sources and the power to lift water, most of the pastoral areas use shallow groundwater, the amount of water coming from water sources is small, and the instantaneous water consumption is large when water is drawn, and there is a problem of mismatching the speed of water supply and demand.
