A photovoltaic step-by-step pumping system suitable for mountainous areas

Abstract

The invention discloses a photovoltaic stepwise pumping system suitable for mountain areas. A pumping pool in a natural water source pumping component is dug in a place of natural water source; a group of first water pumps are arranged in the pumping pool below an impurity filter screen; the electric energy converted by a first photovoltaic combination can supply power to the first water pumps; the altitude of a container in a user water-taking component is higher than that of the natural water source pumping component; the container is communicated with a water-taking pipe; at least two pumping relay components are arranged between the natural water source pumping component and the user water-taking component; second water pumps are arranged in intermediate pools in the pumping relay components and are driven by the electric energy converted by a second photovoltaic combination; the altitudes of intermediate water tanks are higher than those of the intermediate pools; the intermediate water tanks are supported on the ground through intermediate brackets. According to the invention, the photovoltaic stepwise pumping system adopts a stepwise pumping mode, utilizes solar energy to supply energy, and is clean, environmental friendly, low in price, easy to implement and high in reliability.

Description

technical field [0001] The invention belongs to the field of water transportation, and in particular relates to a photovoltaic type step-by-step pumping system suitable for mountainous areas. Background technique [0002] Water is one of the necessary material resources for production and life, but in many places in our country there is a problem of insufficient supply of water for production and life, such as the southeast of Chongqing, northeastern Guizhou and southwestern Hunan that belong to karst landforms. In these areas, natural water sources and There are not only height differences but also distance differences between user sites. Many residents living in mountainous areas live scattered and far away from natural water sources, which is a common situation of water shortage. Although the government has made great efforts to solve the production and domestic water problems of these residents in various ways in recent years, the problems have not been fundamentally so...

AI Technical Summary

Problems solved by technology

Although the government has made great efforts to solve the production and domestic water problems of these residents in various ways in recent years, the problem has not been fundamentally solved due to reasons such as living habits and cultivated land distribution.

[0003] In addition, some characteristic agricultural products are distributed in high mountain areas, and seasonal water shortages restrict the expansion of planting scale and the improvement of economic benefits, which in turn restricts the development of local social economy

Although the problem of water shortage can be solved by lifting irrigation technology, because the above-mentioned areas are at the end of the power network, the power supply stability is poor, and the local road traffic conditions are poor, the construction is difficult and costly, and economic benefits cannot be discussed.
