Background technology
at present, the main heating system of green house is the heating of stove coal fire, this heating system has a lot of shortcoming, and green house heating period in the winter time, by consuming a large amount of coal and can relating to fire safety problem, exists potential safety hazard, in addition, the high flow rate of coal resources is also a huge threat to national energy security, also brings a series of environmental problem, as air pollution, soil pollution, acid rain etc.Greenhouse System of the present invention adopts clean wind energy and solar energy to replace coal heating, avoids coal fire and adds thermogenetic problems, and improve the intelligent management degree of system.
due to solar energy and wind energy in time, geographically, in performance and all there is certain complementarity economically, therefore can optimize the cooperation of the two, provide stable electric power to meet power demands.The advantage of this complementarity of scene compound power-generating, can make independently solar energy and wind energy combine composition wind light mutual complementing mixed power supply system, improve reliability and the economy of electric power system, provide more stablize lasting electric energy to load.
the combined power supply way of current wind light mutual complementing has also been applied to many fields, technology is comparative maturity, as wind and light complementary road lamp, wind light mutual complementing independent power supply, wind light mutual complementing communication station, wind light mutual complementing water pump etc., this plays important function to economize energy.Greenhouse System of the present invention both adopted the principle of " wind light mutual complementing " to carry out collection of energy, gathered solar energy and wind energy simultaneously, was translated into electric energy and heat energy, provided energy for Greenhouse System runs.
Summary of the invention
the zero-emission Greenhouse System of a kind of wind light mutual complementing power generation of the present invention, overcome the shortcoming that existing Greenhouse System energy resource consumption is many, pollution level is high, intelligent level is low, adopt widely distributed wind energy, the renewable and clean energy resource of solar energy, pollution-free in the cycle of operation, and adaptive faculty is strong, be applicable to each area.
object of the present invention is achieved through the following technical solutions: the present invention adopts wind light mutual complementing power generation technology, whole electricity needs of Greenhouse System are provided, based on solar energy heating heating soil, air heat auxiliary heating, the heat collected is stored in the heat storage water tank be placed in greenhouse, under the effect of control system, when the temperature in greenhouse is lower than its setting value, hot water in Systematical control heat storage water tank passes through circulating pump, heat is sent into continuously in the soil being embedded with ground hot coil, partial heat is transported in air transducer by the air themperature according to greenhouse, greenhouse soil and air themperature is made all to be in the Best Point of plantation, in addition, control system is according to the environmental parameter in greenhouse, with suitable control logic adjustment electricity generation system and energy-storage system, configure the time period of its work, both ensured that the temperature in greenhouse maintained in stable scope, turn avoid unnecessary loss, improve energy utilization rate.
the invention has the beneficial effects as follows: the zero-emission Greenhouse System of a kind of wind light mutual complementing power generation of the present invention, ensure that in the Greenhouse System whole service cycle in the winter time, warm indoor temperature is not less than 20 DEG C, soil temperature is not less than 15 DEG C, and required energy consumption is all self-sufficient, do not produce any pollutant, achieve the zero-emission of greenhouse whole year operation; Improve the availability of green energy resources, the energy supply for greenhouse provides a kind of new scheme.

Embodiment
below in conjunction with accompanying drawing citing, Greenhouse System of the present invention is described in more detail:
embodiment 1
composition graphs 1, Fig. 1 is the master-plan framework of Greenhouse System of the present invention; Electric power system adopts the wind and solar hybrid generating system that present technology is perfect, the generated energy of wind and light generating system can be used for answers all electrical equipments of inside greenhouse, hybrid wind-solar energy device is selected according to the power demand of local meteorological data and user, mainly makes its power meet the demands.In the present system, solar energy soil heating system is independent independently system, adopts flat-plate special solar thermal collector, collects free solar heat, the medium in heating system.This programme can realize green house zero (low) discharge heating substantially.
embodiment 2
composition graphs 2, Fig. 2 is the wind-photovoltaic complementary power supply system structure of Greenhouse System; It is made up of wind power generating set, solar battery array, batteries, controller, inverter, system monitoring system etc.Controller is used for controlling the power distribution that solar cell and wind-driven generator send, and is stored in accumulator, when load is DC load, by the effect of controller, direct current is directly flowed to load; When load is for exchanging, controller resupplies load and uses after first making direct current be translated into alternating current by inverter.
embodiment 3
composition graphs 3, Fig. 3 is that the air of Greenhouse System is for warm air handling system; Under control system effect, the water after collecting system is heated by circulating pump, by heat by the Pipeline transport in canopy in air transducer, in addition, air regulator still uses identical air transducer.When needing to carry out air conditioning, by control system, pipeline is switched, utilize blower fan by fresh air by air transducer, promote booth inner air flow.
embodiment 4
composition graphs 4, Fig. 4 is that the air of Greenhouse System supplies warm air handling system: when being arranged on the hygrosensor in heat collector, when detecting temperature reaches design temperature, intelligent control box starts water circulating pump, and start water filling in combination type solar heat collector, water can produce the hot water of about 50 DEG C through heat collector, hot water is by evenly imbedding about 0.5 meter, underground place, the buried pipe that spacing is 0.5 meter is circulated to water pump, thermal release in soil, directly improves soil temperature.When detecting temperature is lower than design temperature, intelligent control box closes circulating pump, and the water in combination type solar heat collector, gets back to heat preservation storage water tank under the effect of the pressure.
when the hygrosensor installed in attemperater, when detecting water temperature lower than design temperature, closed electromagnetic valve, hot water is by the corrugated pipe coil in attemperater, when water in heating water tank reaches design temperature, opens solenoid valve, hot water, no longer by corrugated pipe coil, directly enters buried pipe and carries out next one circulation.
