Photovoltaic center rotary sprinkler system is an efficient solution combining solar photovoltaic technology and modern agricultural irrigation, which is mainly used for irrigation of large areas of farmland. The following is a description of the core structure and working principle of the system:
System composition
Solar photovoltaic module:
Located on the ground or on an elevated platform, it is used to convert solar energy into direct current electricity.
The design can meet the power requirement of sprinkler irrigation system operation.
Controllers and inverters:
Controller: regulates the output of the photovoltaic panel, protects the battery and load equipment.
Inverter: Converts direct current into alternating current to drive the motor and pump of the sprinkler irrigation system.
Energy storage unit (optional):
Equipped with batteries to store excess solar energy to support irrigation needs at night or in rainy weather.
Pumps and pipes:
The water is pumped by an electric pump to the main pipe of the central rotary sprinkler system.
The central pipeline is connected with multiple nozzles through the support arm, and the water flow is evenly distributed
to the field under the action of pressure.
Center rotation structure:
With the fixed center as the axis, the support arm rotates to cover the entire irrigation area.
The arm is usually equipped with multiple efficient sprinkler heads, and the coverage can be adjusted according to the length
of the arm.
Field sensor (optional):
Monitor soil moisture, temperature and weather conditions and provide intelligent irrigation advice.
Working principle
1.Energy supply
During the day, photovoltaic modules collect solar energy and supply water pumps and rotary sprinkler systems. Excess power can be stored in a battery.
2.Flow distribution
The pump draws water from an underground well or reservoir and pipes it to a rotary sprinkler system.
3.Automatic control
The amount and timing of sprinkler irrigation can be adjusted according to crop needs, weather and soil conditions through an intelligent controller.,
4，Rotating covering
The arms rotate slowly around the center point and use the sprinkler to evenly distribute water to the field to achieve large-scale irrigation
