Description

From motion tracking photovoltaic plant equipment

Technical field

This utility model relates to a kind of photovoltaic power generation equipment, particularly relates to one and can realize position of sun omnidirectional tracking Large-sized photovoltaic power station equipment.

Background technology

Solar energy is inexhaustible, utilizes solar electrical energy generation environmental protection by photovoltaic power generation technology, obtains It is widely applied.Photovoltaic power generation equipment accepts solar energy and generates electricity, its generated energy and the solar radiation received Amount has directly association, compared to fixedly mounted photovoltaic plant equipment, has the photovoltaic plant equipment energy of following function Tracking position of sun also makes photovoltaic module sensitive surface try one's best vertical with sunray, and its result substantially can obtain the sun of maximum Energy amount of radiation, thus obtain the generated energy of maximum.

The sun rises every day eastwardly, west falls, and according to the difference in season, the excursion of its elevation angle is at 0-90 Between degree, its azimuthal excursion is maximum up to positive and negative 120 degree, and throughout the year in, every day sun altitude and orientation The excursion at angle also differs.The photovoltaic generation station equipment with double-axis tracking function makes photovoltaic module be subject to by following the tracks of device The angle position of bright finish is corresponding with the elevation angle of the sun and azimuth position, is usually predominantly by arranging around along east-west direction Axle carry out rotating and realize tracking to sun altitude, and by rotating around the axle or the vertical axis that arrange in North and South direction Realize the tracking to solar azimuth, correspondingly derive the tracking device of a lot of form, its camber according to this principle The tracking at angle facilitates relatively and the elevation angle following range of all kinds of tracking device substantially can be corresponding with position of sun, and for side The tracking of parallactic angle, owing to the azimuth range of the sun is big, can not be complete by carrying out rotation along the axle arranged in North and South direction Orientation, trace into position of sun to all the period of time, be to realize following the tracks of, by carrying out along vertical axis in the range of positive and negative 90 degree mostly Can realize the omnidirectional tracking to solar azimuth although rotating, but its structure is complicated, working service cost is high, actually used It is worth the highest；And photovoltaic module and mounting bracket thereof are essentially all and are in photovoltaic group by one on above-mentioned all kinds of tracking devices The column supporting in part mounting bracket centre, module mounting bracket surrounding is to overhang outside, thus its assembly is installed and propped up Frame must have enough rigidity, and when device of solar generating reaches certain installed power, owing to component count increases, group The overhanging of part and module mounting bracket is longer, if relying on merely module mounting bracket to improve the integral rigidity in power station, then must Its volume so can be made to increase with weight, the burden of column, and corresponding drive mechanism load increasing, cause in actual motion Fault rate is high, is difficult to normal work, and using effect is undesirable.

Authorization Notice No. be CN 102868322 B patent of invention cable wire control sun-tracking solar generating equipment and Application publication number is the automatic sun-tracing regulation device of the patent of invention solar electrical energy generation unit of CN 103455044 A, including center pillar And rotating support is in the solar electrical energy generation module on center pillar top, is provided with first and second coiling apparatus, leads to respectively on center pillar Cross first and second cable wire be connected with solar electrical energy generation module mounting bracket corner and drive solar electrical energy generation module to adjust orientation Angle, also utilizes this two cable wire solar electrical energy generation module to be fixed simultaneously, thus reaches the purpose of tracking position of sun.On Although state patent of invention can in certain scope tracking position of sun, but photovoltaic module and module mounting bracket thereof be by Post supports, though then module mounting bracket possess good rigidity be also difficult to ensure that its deadweight effect under do not produce sagging Deform, and two cable wires being used for driving and regulating photovoltaic module orientation angles undertake photovoltaic module and mounting bracket thereof simultaneously The function being fixed, is equivalent to be buckled on middle pillar support photovoltaic module and mounting bracket bolt thereof, so certainly will be to photovoltaic group Part and mounting bracket thereof produce a downward fastening pulling force, the direction of its fastening pulling force and photovoltaic module and mounting bracket thereof Gravity direction is the same and acts on downwards, and this will necessarily strengthen the deformation of solar electrical energy generation module and mounting bracket thereof, thus shadow Ring the properly functioning and service life of whole generating equipment.Therefore, the technical scheme of foregoing invention patent has bigger defect.

In order to improve the integral rigidity of such photovoltaic power generation equipment, reduce photovoltaic module and the deformation of mounting bracket thereof, It is a kind of admissible scheme that module mounting bracket periphery arranges support member, but photovoltaic module angle during daily tracking Excursion is big, and the edge of module mounting bracket excursion when subaerial extreme lower position changes to extreme higher position connects The length of side of nearly module mounting bracket, thus provide the support member supported to be necessary for having the biggest length for module mounting bracket and become Change scope, the supporting construction of conventional adjustable length cannot meet the change requirement of its length, this such light the most existing Volt generating equipment is all the reason place of only one independent middle standing pillar, be also cause above-mentioned form there is double-axis tracking merit The photovoltaic power generation equipment of energy is difficult to the root place promoted in reality application.

Utility model content

For the above-mentioned deficiency existing for prior art, technical problem to be solved in the utility model is to provide one certainly Motion tracking photovoltaic plant equipment, it can not only realize the omnidirectional tracking to position of sun, and the installed capacity of generating equipment Greatly, supporting is reliable.
