Water-saving trickle irrigation device for long-distance water supply in desert by taking photovoltaic power generation as power supply

Abstract

The invention relates to a water-saving trickle irrigation device for long-distance water supply in desert by taking photovoltaic power generation as power supply, which belongs to the technical field of the environmental protection. A solar cell is connected with a photovoltaic controller through an electric lead, the photovoltaic controller is connected with an energy storage battery through the electric lead, the energy storage battery is connected with a control device through the electric lead, and the control device is connected with a branching device and a water pressure device through electric leads. Currents produced by the solar cell can be input into the photovoltaic controller through the electric lead to be adjusted and then, can be input into the energy storage battery to be stored, and the current output by the energy storage battery provides electric power to the control device. The current is transmitted to the branching device by the control device according to operating instruction information, part of water is branched out from water flow in a water pipe by the branching device, the water is transported into a trickle irrigation pipe by a water supply pipe, and the water drops into the soil of roots of desert plants from an outlet of the trickle irrigation pipe. The current is transmitted to the water pressure device by the control device according to the operating instruction information, and the water flow input by the water pipe is pressurized to be input into a next section of the water pipe by the water pressure device.

Description

technical field [0001] The invention relates to a water-saving drip irrigation device for long-distance water supply in deserts using photovoltaic power generation as a power supply, and belongs to the technical field of environmental protection. Background technique [0002] Among the anti-sand forest systems established in desert areas, some anti-sand forests stretch for thousands of kilometers at the edge of the desert, and some go deep into the center of the desert for more than 100 kilometers, effectively preventing the spread of the desert and reducing the risk of sandstorms. occur. In the process of planting sand-resistant trees to establish new sand-resistant forests, supplying necessary root water to newly planted sand-resistant trees can effectively improve the survival rate of sand-resistant trees; , supplying water to the roots of the sand-resistant trees in the sand-resistant forest can also improve the survival rate of the sand-resistant trees. However, in th...

Problems solved by technology

However, in the long-distance water delivery in the desert, the longer the distance, the higher the requirements for the pipeline, which increases the cost; to establish a water supply relay station, it is necessary to provide power for the water supply relay station, and to install and lay cables in the desert is not only time-consuming and laborious, but also increases the cost. cost of water supply

Photovoltaic water pumps currently used relying on solar power to provide electricity can only supply water to sand-proof trees in a small range and short distance, and cannot reasonably allocate water resources, let alone achieve large-scale and long-distance sand prevention. sand-resistant trees in the
