Description
Technical field
A kind of diesel generation and photovoltaic generation complementation are applied in the power set on the grain header, belong to technical field of new energy application.
Background technology
In recent years, making rapid progress of solar photovoltaic technology, Jiangsu still moral photovoltaic technology research institute is invested 2.6 hundred million yuan of scientific research, technological development, technology of carrying out the photovoltaic industry field and is applied, the Pluto battery technology of research institute's exploitation, be in the leading level in the world, can make the monocrystaline silicon solar cell conversion efficiency reach 18.8%, the polysilicon solar cell conversion efficiency reaches 17.2%, and New Polycrystalline silicon assembly conversion efficiency is up to 16.5%; Research institute is that Shanghai World's Fair theme shop Roof Design installation solar-electricity tankage is 2825 kilowatts, and 3.1 ten thousand square metres of the gross areas are the present solar roofs of unit are maximum in the world.Annual generated energy 2,840,000 degree of whole 3.12 megawatt solar roofs are equivalent to annual 1000 tons of the standard coals of saving, annual about 2500 tons of the CO2 emissions that reduces.
The China holding Co., Ltd of first photovoltaic enterprise STP electric power shipment amount in 2009 is 704 megawatts, 91.48 hundred million yuan of total profits, shipment amount will reach 1250 megawatts in 2010, and corporate president doctor Shi Zhengrong to the promise that Chinese make is: solar energy electricity price and thermal power generation electricity price maintain an equal level.Increase the solar electrical energy generation amount, reduce the coal and oil generated energy, help preserving the ecological environment.On June 21st, 2010 is in Shanghai Expo (scientific and technical innovation and city future) forum, doctor Shi Zhengrong points out: because the adjustment of development of technology and supply chain, the production cost of solar electrical energy generation reduces significantly, will have increasing people and afford to use solar panel and solar-photovoltaic technology.What we will be clear that sees, oil is the productive life in remaining 37 years only, estimates that 70% power supply will be provided by solar energy before 21 century end.
Nearly 500,000 grain headers of China all rely on fossil energy that power is provided at present.The black smoke of emerging the Diesel Engine Exhaust Pipe from grain header, main component are carbonic acid gas and pernicious gas, are polluting the air of rural area cleaning, the contaminated by diesel oil of careless run, drip, leak limpid river, rural area; The inventor's son Miu Jiangqiao once eats freshwater fish at home, and just having had has the diesel oil flavor in the flesh of fish, and a large amount of diesel engine and gasoline engines of using can pollute the fine natural environment in rural area in the rural area.Chinese countryside has 500,000 grain headers, and this numeral is also among increasing year by year.Grain header is the agricultural machinery of the long-pending amount of the exposing to sunlight maximum of fuselage surface, the body surface at the body both sides of a large-scale combine, front portion, rear portion, top is long-pending adds up above 100 square metres, it can also erection space above grain header be 100 square metres to 200 square metres tall and big sunshade ceiling, at present, the energy that throughout the year shines the solar energy on the grain header wastes, and can not obtain utilizing.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, provide the area of the tall and big ceiling of a kind of body that makes full use of grain header and grain header top to accept the long-term radiation of sunlight, large tracts of land is installed solar cell and is accepted solar energy, on grain header, carry out solar electrical energy generation, electric energy is directly supplied nearby as the part power of grain header finished the harvesting operation.The body both sides of a large-scale combine, anterior, the rear portion, the surface area at top is added up above 100 square metres, above grain header, it can also erection space be 100 square metres to 200 square metres tall and big sunshade ceiling, add up to the irradiation that has 300 square metres area can be used to accept sunlight, 200 of annual average solarizations have solar day, if solar cell all is installed on this area of 300 square metres, shine 200 arranged solar day, and the electrical power storage that solar energy is sent, concentrate and be used in 50 harvesting operation days, emit electric energy and drive grain header and carry out operation, photovoltaic generation can be supplied a part of power until whole power to grain header.Before the energy that photovoltaic generation provides can't all satisfy the power demand of grain header, also need complement one another, provide jointly electric energy to satisfy the demand of grain header by diesel generation and photovoltaic generation to power.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The silicon solar cell that turns to support bar 19 upper ends day by day 1 that solar light irradiation is installed in bavin electric solar energy photovoltaic hybrid electric grain header 20 tops produces direct currents with the thin-film solar cells 5 that is attached on the fuselage surface, after direct current input controller 3 is adjusted, then import inverter 4 and convert alternating current to, alternating current input power distribution station 17 merges with the alternating current of exporting from diesel generating set 8, alternating current from power distribution station 17 outputs, drive header 12 respectively, electronic feeding unit 18, electronic sheller unit 16 and electronic cleaning plant 6, the band fringe rice straw or the band fringe wheat straw that cut off are transported to electronic sheller unit 16 and electronic cleaning plant 6 by electronic feeding unit 18, finish the threshing of grain, behind the prune job, storage is in the inside of silo 7 temporarily, the loading gunnysack that grain is irritated in the loading compartment 10 into by the outlet of unloading funnel 9 prepares to transport grainfield, is used to import the illumination of the LED illuminating lamp 21 that is installed in rear portion, bavin electric solar energy photovoltaic hybrid electric grain header 20 both sides from the one part of current of power distribution station 17 outputs; The driver is sitting in the control stick of handling on the driver's seat 15 on the bridge 13 14, and guiding crawler type self-walking apparatus 11 loads bavin electric solar energy photovoltaic hybrid electric grain header 20 to overtake.
1-20 silicon solar cell 1 is monocrystaline silicon solar cell or polysilicon solar cell.
Thin-film solar cells 5 is: cadmium telluride diaphragm solar battery or gallium arsenide film solar cell or copper-indium-galliun-selenium film solar cell or silicon-based film solar cells.
