Abstract
The utility model relates to a solar photovoltaic pumping drip irrigation system which consists of a solar photovoltaic array, a pumping inverter, a three-phase water pump and an impounding reservoir. The off-grid/grid-connected automatic switching of the pumping inverter can effectively improve the practical effectiveness of the solar photovoltaic pumping drip irrigation system. The impounding reservoir can be used for effectively regulating a water pressure of a drip irrigation tape by impoundment.
Description
Technical field
It is the farmland drip irrigation system of the energy with the solar energy power generating that the utility model relates to a kind of.
Background technology
What drip irrigation required electric power in field all adopted in the past is alternating current.There are shortcomings such as electrical network sets up, maintenance cost high, and floor space is many.In recent years, the drip irrigation system of electric energy occurred partly providing, but the overwhelming majority was the small-sized drip irrigation system that is used for small size irrigated areas such as vegetable garden with solar energy.Along with the reduction of cost for solar power generation, photovoltaic pumps up water, and the drip irrigation direction develops drip irrigation towards the large tracts of land farmland.
Summary of the invention
For effectively improving the usefulness of utilizing of solar energy drip irrigation; The present invention provides a kind of photovoltaic drip irrigation system that pumps up water; This system adopts solar energy power generating to obtain electric energy; The inverter that pumps up water has from the net/selection gauge tap that is incorporated into the power networks, and the net pattern that is incorporated into the power networks/leaves of the inverter that pumps up water is controlled in the keying of switch, and the cistern outer wall has piezometer and a plurality of mouth of pipe.
The technical scheme that the utility model adopts is: system comprises the solar energy photovoltaic array, the inverter that pumps up water, three-phase water pump, cistern.The solar energy photovoltaic array provides electric energy, and the inverter that pumps up water converts direct current into three-phase alternating current, simultaneously through the monitoring load feedback signal, and the inverter network operation that is incorporated into the power networks/leaves of realizing pumping up water of the keying through selector switch.When being incorporated into the power networks, electric energy inserts electrical network, is not the water pump power supply; When net, electric energy breaks away from electrical network, drives three-phase water pump groundwater abstraction.The cistern storage of water, piezometer shows the pressure of cistern inner storing water, the number of pressure switch control cistern delivery port.
The beneficial effect of the utility model is:
1, the inverter that pumps up water has from net/two kinds of operational modes are incorporated into the power networks.Winter, invertor operation was in the pattern of being incorporated into the power networks when need not drip irrigation, and system's generating is surfed the Net; All the other is during drip irrigation in season, and invertor operation is in from the net pattern.Thereby reach the pump up water maximization of drip irrigation system usefulness of photovoltaic.
2, abandon and adopt accumulator accumulation of energy pattern in the past, with retaining can replace electric power storage can, when improving system's drip irrigation effect again, significantly reduced the construction cost of system.
3, can carry out farmland large tracts of land drip irrigation.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
1 is photovoltaic array among the figure; The 2nd, inverter pumps up water; The 3rd, the three-phase water pump; The 4th, and network interface; The 5th, cistern; The 6th, deep well.
Embodiment
In the native system, solar light irradiation photovoltaic array 1, photovoltaic array 1 conversion solar can be electric energy; Photovoltaic array 1 is connected through cable with the inverter 2 of pumping up water, and the inverter 2 that pumps up water converts electrical energy into three-phase electricity output, pump up water inverter 2 through cable connect simultaneously water pump 3 with and network interface 4; Water pump 3 through water pipe with below deep well passes to the well water level mutually; And network interface 4 links to each other with electrical network; Cistern 5 and water pump 3 are connected through water pipe, and outer wall has a plurality of pressure switches and a piezometer.
