Description

Removable A-frame for photovoltaic generation
Technical field
This utility model relates to photovoltaic generation support technology field, is specifically related to a kind of removable A-frame for photovoltaic generation.
Background technology
Along with the reserves of non-regeneration energy (such as petroleum chemicals) are fewer and feweri, regenerative resource just becomes the only way of our the Future Development energy, and regenerative resource is mainly based on water energy, wind energy and solar energy.Along with science and technology development, large solar photovoltaic generation, progressively accomplished.Due to the particularity of solar energy power generating, corresponding environment be it is also proposed higher requirement, for instance sufficient sunlight, the area etc. of the length and breadth of land.Desert is undoubtedly the optimal place of solar energy power generating.
Utilize desert to carry out large solar photovoltaic generation and there is some feature following:
(1) vast in territory, do not strive useful ground with people: in the desert of state-owned 710,000 square kilometres, reach 128 square kilometres together with the Gobi desert gross area.
(2) sunny: on desert, sunshine has 10-12 hour every day, having 7-10 every year is without rain day in individual month, even if raining, each rainy spell is all very short, often only has the time of a few minutes, annual sunshine, duration was at 2500-3600 hour, say, that have the time of 30%-40% to be subject to the irradiation of sunlight in the whole year, and in desert, total radiation is generally at 140-170 kilocalorie/square centimeter solar year.
(3) be conducive to the transformation in desert, be conducive to the growth of plant: the large area because of solar energy power generating square formation is installed, and has blocked the sunlight direct irradiation to ground, it is possible to reduce the substantial amounts of evaporation of desert subsoil water.In desert, some places only have the rainfall of 3.9 millimeters every year, and evaporation capacity is extremely strong, learns according to the analysis of many annual mean ground temperature, evaporation capacity is generally at 2500-3000 millimeter, some places height 4000 millimeters, exceedes tens times of precipitation, even hundreds of times.It addition, when solar module uses as building block the aeration-cooling weak effect in its back side because when improper ventilation, solar module back temperature may be up to more than 70 DEG C.But well-ventilated on desert, can reduce temperature, reduces evaporation of water, the growth of favourable plant.
Desert is built large-scale solar photo-voltaic power generation station and there is also following difficulty:
(1) owing to the wind on desert is relatively larger, the solar energy power generating bracing frame of conventional structure would generally deform by recurring structure, affects the work efficiency of solar energy photovoltaic panel;
(2) solar energy photovoltaic panel is because of the abrasion of dust storm, and the dust storm of aerial flowing is more serious to surfaces of cell abrasion;
(3) drift sand is buried, and on desert, drift sand is serious, easily there is the danger that solar photo-voltaic power generation station is buried by drift sand;
(4) illumination is collected low, owing to the sun is motion, the illumination spot on desert can passage in time and change.
Existing urgent need designs a kind of solar photovoltaic bracket for desert Environment in sum, and this support not only can prevent wind structure to be unlikely to deform, and can also prevent from being buried by drift sand accepting, with illumination, the feature that efficiency is high.
Utility model content
The purpose of this utility model is in that providing one not only to have prevents wind from causing malformation, but also has and prevent from being buried by drift sand accepting, with illumination, the solar photovoltaic bracket that efficiency is high.
For reaching above-mentioned purpose, base case of the present utility model is: for the removable A-frame of photovoltaic generation, including support portion and rotation section, support portion includes at least two horizontally disposed horizontal beams, the two ends of adjacent level beam connect respectively through triangular plate, being provided with rotating shaft between the top of two triangular plates, rotating shaft is installed below motor, and the output shaft of this motor is provided with revolving meber;Rotation section, including one group of horizon bar and one group of vertical bar, horizon bar is connected with vertical bar, and vertical bar or horizon bar are connected with rotating shaft, horizon bar or vertically bar are provided with two connectors being arranged symmetrically with about rotating shaft, this connector is provided with the flexible piece walking around revolving meber.
Operation principle and the advantage of this programme are in that: during specifically used A-frame, on desert, one piece of Shamian Island being suitable for placing A-frame is released first with engineering machinery such as forklifts, then A-frame is lain on Shamian Island, solar energy photovoltaic panel is fixed on rotation section.Now solar energy photovoltaic panel is parallel with a side of triangular plate, solar panels just direction to sunlight in the morning.
Noon, when the sun is vertically pointed into Shamian Island, starts motor, driven by motor revolving meber rotates, and the flexible piece length making revolving meber both sides is equal, and solar energy photovoltaic panel rotates 60 degree, now solar energy photovoltaic panel is horizontal, and sunlight direct projection is to solar energy photovoltaic panel.
When afternoon, the sun moved, being again started up motor, make revolving meber be rotated further, solar energy photovoltaic panel is rotated further by 60 degree, and now solar energy photovoltaic panel is parallel with another side of triangular plate.Solar energy photovoltaic panel receives the illumination that afternoon, the sun sent.In evening, motor opposite direction rotates, and makes solar energy photovoltaic panel reset to original state.
