Agricultural drip irrigation system employing solar microgrid as power supply

Abstract

The invention belongs to the technical field of agricultural irrigation, and discloses an agricultural drip irrigation system employing a solar microgrid as a power supply. The system is provided witha solar cell panel, a power storage device, a controller, a humidity sensor, a power switch, a pump body, a water source, a pipe, a spraying connector, a support, a drip irrigation system terminal, adata transmission system, an adjustment unit, a relay station, and a feedback system. The solar cell panel is fixed on the support, and is electrically connected with the power storage device at thelower part of the support. The controller is connected with the power storage device and the humidity sensor. One end of the power switch is connected with the power storage device, and the other endof the power switch is connected with the pump body. The pump body is connected with the water source through the pipe. The system achieves the intelligent irrigation of a farmland, saves the energy,and overcomes a difficulty that a farmland far from the power facilities is difficult to irrigate. The system can control the water spraying camber of an irrigation device through the adjustment of awater speed adjustment rotary knob, can meet the small-area and big-area sprinkling irrigation of plants, saves a large amount of manpower and material resources, and improves the utilization rate ofwater resources.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation, in particular to an energy-saving and environment-friendly irrigation system. Background technique [0002] At present, scientific irrigation has a great impact on agricultural production. Some areas lacked effective precipitation, and many crops in the fields withered and turned yellow, and some even died. Due to the high cost of artificial irrigation, the rural areas in the disaster-stricken areas are still "relying on the weather". Once a disaster occurs, their self-rescue ability is very limited. Farmland irrigation in vast rural areas is relatively concentrated in terms of power consumption time. During the irrigation season, the agricultural power load increases sharply, greatly increasing the power supply pressure of the power grid, and even causing power cuts in some areas. To meet the demand for irrigation load in these areas, it may be necessary to increase the capacit...

Problems solved by technology

Due to the high cost of artificial irrigation, the rural areas in the disaster-stricken areas still "rely on the sky for food". Once a disaster occurs, their self-rescue ability is very limited

Farmland irrigation in vast rural areas is relatively concentrated in terms of power consumption time. During the irrigation season, the agricultural power load increases sharply, which greatly increases the power supply pressure of the power grid, and even causes power cuts in some areas.

To meet the demand for irrigation load in these areas, the capacity of the main transformer may need to be increased, but the load rate of the irrigation type is low and the duration is short, so the economy is poor

In some areas without electricity, there is no low-voltage power supply line that can be used to drive water pumps for irrigation, so small diesel engines are used as power to drive water pumps for irrigation. This has several disadvantages: (1) The combustion of diesel oil produces pollutant emissions, which is not conducive to Energy saving and environmental protection; (2) The majority of agricultural practitioners do not have the habit of storing oil, resulting in a tight supply of diesel oil during the irrigation period, while the sales of diesel oil during idle hours cannot be guaranteed; (3) The requirements for energy quality for irrigation are not high. Use high-quality primary energy consumption to meet low-quality energy demand, which is not conducive to energy efficiency and environmental protection

[0006] To sum up, the problems existing in the existing technology are: part of the irrigation in agricultural production areas needs to be close to the power supply system to further increase the power load when the power supply is tight, and the other part has to use diesel engines to drive water pumps due to the lack of low-voltage power supply in regional irrigation technology, causing environmental pollution ; and can not control the sprinkling arc of the sprinkling irrigation device, it is difficult to meet the small area and large-scale plant sprinkling irrigation

Moreover, the existing irrigation system has a low degree of intelligence and poor data processing capabilities.
