Description
Technical field
The present invention relates to a kind of solar energy equipment, particularly a kind of solar light tracking device.
Background technology
With the development in epoch, science and technology is advanced by leaps and bounds, but at the same time the burden on society and responsibility of the mankind be also therewith
Increase.The energy is the basis of national economy and social development, and socio-economic development must be faster, the mankind to the demand of the energy also
It is bigger.Nowadays, coal, oil, a large amount of use of natural gas equal energy source cause severe environmental pollution and destruction.This also causes environment
Problem is increasingly serious with energy problem, and the sun is an energy body beyond imagination.The stored energy overwhelming majority on the earth
Give the credit to the good fortune of the sun.Nowadays, coal, oil used in the mankind be all derived from ancient times be imbedded under soil layer animal or
Plant, is exactly to be collected the solar energy buried in underground after all.The sun is to propagate its energy to surrounding in the way of radiation
Amount, the sun is radiated equivalent to 181,300,000,000 tons standard coals of tellurian energy every year, is that the whole world year needs the 5000 of energy summation
Times, it is the energy maximum on the earth.Various energy sums used in global human 1 year also only reach the sun of earth surface
The number a ten thousandth of energy, solar energy is compared with other energy (such as coal, oil, nuclear energy), with advantages below:
1. generality.In the world all there is the not enough situation of energy supply in most of country, according to statistics fossil in nearly 10 years
Fuel (coal, oil and gas etc.) energy expenditure adds nearly 20 times, it is contemplated that the consumption of 10 years fossil fuels will turn over one from now on
Kind, but the whole world oneself the petroleum reserves verified can only use the year two thousand fifty, natural gas can only also be extended to or so the year two thousand forty, even if reserves
Abundant coal resources can only also be maintained 200 or three hundred years.And for solar energy, every nook and cranny is all present on the earth, it is not necessary to by spy
The fixed place of production is transported all over the world, is also saved many processing costs while convenient conveying, is improved economic benefit.
2. the feature of environmental protection.Due to fossil fuels such as burning coal, oil, there are the harmful substances such as few hundred thousand tonnes of sulphur every year under soil layer
It is transferred in air, at the same time, producing substantial amounts of greenhouse gases also causes greenhouse effects, causes Global climate change, Hai Ping
Face rises, and environment directly affects the healthy and quality of life of resident by severe contamination and destruction.Formed in some areas
Acid rain, severe contamination water and soil.By the use of solar energy as the energy, without waste residue, waste material, waste gas, the discharge of waste water, without noise,
Do not pollute the environment.
3. permanence.According to the reckoning of astronomical science man, the sun exists about 4,600,000,000 years in the milky way galaxy, and it can be with
Burn away about 5,000,000,000 years.As long as so the mankind visible future it is sure see the sun, also should not just suspect solar energy
Existence, therefore solar energy can be described as the inexhaustible energy.
4. economy.The solar radiant energy total amount that ground is reached in 1 year is the existing various energy summations consumed on earth
Tens of thousands of times, and receive solar energy do not receive any alternative energy usage charges, can take everywhere；Moreover in current technology
Under development level, oneself has economy to some Solar uses, and the skill of solar energy is utilized with the development and human development of science and technology
Art breaks through, and the economy of Solar use will become apparent from.
As can be seen here, solar energy has huge application potential and the market space, is the cleanings such as this large-scale popularization solar energy
The energy, will be the developing direction of the human future energy, be also a great project benefited for descendants.
Current application of solar energy technology generally existing utilization rate is low, the shortcoming that conversion ratio is low, and many occasions are too
Positive energy cell panel (collecting plate), which is installed, fixes, and what is had can only deflect according to fixed direction, it is impossible to make lighting surface all the time against too
Sunlit direction, reduces the utilization rate of solar energy.In order to sufficiently utilize solar energy source, application of solar energy is improved
The efficiency of device, we devise the device for being capable of real-time tracing position of sun.
