Description

A kind of solar tracking device

Technical field

The utility model relates to a kind of tracing positioning apparatus, is specially a kind of solar tracking device.

Background technology

Along with the mankind's development and progress, global energy crisis has become the reality of having to face in countries in the world, and each state all begins to seeking new energy solution effort.Scientific research shows that it is very huge to be radiated at tellurian sun power, is radiated at tellurian sun power, the consumption that just is enough to supply 1 year energy of global human in about 40 minutes.And solar electrical energy generation can not pollute the mankind's environment, uses more conveniently yet, meets the choice criteria of new forms of energy under the current global energy crisis fully.

Sun power refers generally to the emittance of sunshine.Arrive the atmospheric sun power of the earth; 30% by the atmospheric envelope reflection, and 23% by the atmospheric envelope absorption, and remaining arrives earth surface; Its power is 80,000,000,000,000 kilowatts, that is to say that the sun shines the tellurian energy heat that 5,000,000 tons of coals discharge that just is equivalent to burn p.s..China's top is accepted solar radiant energy and be equivalent to 49,000 hundred million tons of standard coal equivalents every year, approximates the summation of up to ten thousand Three Gorges Projects generated energy.The prospect of utilizing sun power is also generally good by people, and consistent think sun power will become human after the necessary novel energy of development.With regard to China, ground such as Ningxia is northern, Gansu is northern, east, Xinjiang, western part, Qinghai and western part, Tibet all belong to the abundant area of solar energy resources, west area, Tibet especially, and sunshine amount is up to 2333 KWh/m ², day radiant quantity 6.4KWh/m ², occupy the second place of the world, be only second to the Sahara desert.But because the two big difficult points that sun power utilizes, the one, the energy density of sun power is low, causes the solar facilities cost high, so must adopt material or optically focused system cheaply; The 2nd, the diurnal variation of sun power with can change the fluctuation of energy that causes, the sun all the time the vertical irradiation solar facilities and overcast and rainy, night sun power the energy storage situation, make these regional solar energy utilization rate have only about 5%.

Improving rate of energy is one of important means that solves energy crisis.Such as, adopt condenser to improve and shine upon the energy density on unit area, thereby overcome the dispersed shortcoming of sun power; Use new material to make conversion of solar energy become the efficient of electric energy to be multiplied; The novel semiconductor material of developing will make solar cell absorb more solar energy, and then can change into more electric energy etc.At present; The most frequently used and most convenient still adopt solar tracking and locating device; The irradiation that guarantees solar utilizing equipment and sunray keeps vertical; Can significantly improve the absorption and the utilization ratio of sun power so significantly; Existing sun follower all needs the angle according to the different sun constantly place of the every day in the information calculations such as longitude and latitude 1 year of laying a little, and each position of sun constantly in a year is stored in PLC, single-chip microcomputer or the computer software, just leans on and calculates position of sun with the realization tracking.What adopt is that computer data is theoretical, need earth longitude and latitude area data and setting, in case install, just inconvenience is moved or mounting or dismounting, has moved just must reset data and adjust each parameter at every turn; Principle, circuit, technology, equipment are all very complicated, and the layman can not at will operate, and costs an arm and a leg, and can't promote, and especially is utilized in the track and localization on the solar water heater.
