A kind of roof photovoltaic bracket
The utility model relates to field of photovoltaic technology, is specifically related to a kind of roof photovoltaic bracket.
The contradiction of photovoltaic industry production capacity surplus is long-standing.China's photovoltaic module output since two thousand seven, occupies the first in the world in continuous 5 years.2011, China's photovoltaic module output was 10 times that increase installed capacity then newly, and the photovoltaic module of 90% needs exportation abroad.
The risk of China's photovoltaic industry heavy dependence overseas market was completely exposed in American-European " two anti-" time.For saving China's photovoltaic industry, country puts into effect the development of policy support distributed photovoltaic power generation this year continuously.In order to respond national policy, State Grid Corporation of China issues distributed photovoltaic power generation related management way, for promoting that solid foundation has been established in the fast development of distributed power generation.
Distributed photovoltaic power generation presents explosive growth in nearly 3 years.China came into effect bidding for concession from 2009, promoted the construction of ground large photovoltaic plant.In the same year, start " the golden sun " engineering and photoelectricity building demonstrative project, give the subsidy of distributed photovoltaic power generation system, and according to the size of scale of investment, determine to subsidize amount.By the end of the year in 2011, the photoelectricity building demonstrative project scale that country has announced will be about 300,000 kilowatts; The scale that " the golden sun " engineering has been announced is about 1,170,000 kilowatts.Distributed photovoltaic power generation explosive growth, but the standard of associated planning, design, construction, management and operation, specification are unsound, cause manifesting in problem set.
The Correlative plan of national publication proposes, and within 2015, distributed photovoltaic power generation will reach 1,000 ten thousand kilowatts.Meanwhile, clearly propose to encourage the distributed photovoltaic power generation system with Integration of building of building in Middle Eastern.Therefore, distributed photovoltaic power generation is following important development direction.
Photovoltaic generation is the important emerging strategic industries of China, and photovoltaic generation is conducive to the paces accelerating Energy restructuring, strengthens clean energy resource supply, makes up the deficiency of primary energy shortage.Namely the generating of distributed photovoltaic roof utilizes idle roof to carry out solar energy power generating by installation photovoltaic component.Country encourages the distributed photovoltaic power generation application carrying out various ways.Make full use of the building roof resource satisfied the requirements, the development zone that encouragement roof area is large, power load large, mains supply price is high and large-scale industrial and commercial enterprises take the lead in carrying out distributed photovoltaic power generation application.
Solar panel many employings strip footing is installed on existing cement roof, due to roof installing solar photovoltaic component, overriding concern roof waterproof, roof construction can not break the original watertight composition of ring, also need in addition to consider that roof solar power station will meet wind load and snow load requirement, therefore can select to be furnished with the mounting bracket of photovoltaic bracket as solar photovoltaic assembly of strip footing, to meet above requirement.But, after photovoltaic plant is arranged on roofing, need operation 25 years, its deadweight belongs to dead load, and use the photovoltaic bracket of strip footing, overall weight is large, require high to effective dead load on roof, construction cost is high, is not suitable for the non-upper people roof that effective dead load is lower.
Summary of the invention
It is not enough that the purpose of this utility model is to overcome a kind of roof of existing concrete roof photovoltaic bracket basic technology, provides a kind of intensity high and a kind of roof photovoltaic bracket of good corrosion resistance.
The technical scheme solved the problems of the technologies described above is as follows:
A kind of roof photovoltaic bracket, comprise at least two the first supports along ground transverse arrangement of turbo, and at least two the second supports longitudinally arranged along ground, one end of second support is fixedly connected with one end of the first support, two adjacent the second supports are connected by spoiler, and the first support, the second support and spoiler all adopt fiberglass reinforced plastics to be made.
Preferably, the other end of the first support and the second support is equipped with connector.
Preferably, described connector comprises pedestal and briquetting, and one end of described pedestal is provided with the liner plate along ground horizontal expansion, and described briquetting is fixed on liner plate.
Preferably, described connector adopts fiberglass reinforced plastics to be made.
Preferably, also comprise balancing weight, this balancing weight is pressed on the first support.
Preferably, between first support and the second support at described photovoltaic bracket two ends, first spoiler is connected.
Preferably, described first spoiler adopts fiberglass reinforced plastics to be made.
Have employed such scheme, the utility model adopts fiberglass reinforced plastics to be the roof photovoltaic bracket that material makes, due to 1.5 ~ 2.5 times that fiberglass reinforced plastics tensile strength is steel, density is 1/5 ~ 1/4 of steel, has not corrosion, nonmagnetic, electric insulation, in alternating current and high-frequency signal occasion, there is no eddy current loss, there is no the advantages such as eddy current interference, be a kind of high-strength, light weight, there is the Novel engineering component of superior electromagnetic property.Thus effectively can reduce photovoltaic generating system to the impact on existing building structure; Ensure that load is still in former design safety scope; Roofing is accomplished " not destroying " or " destroying minimum "; Shorten the project construction cycle, reduce construction cost; Supporting structure makes every effort to simple, is convenient to rapid construction and installs.
A kind of New-support that this novel employing support combines with spoiler, support has corrosion-resistant, that quality is light, attractive and durable feature, and spoiler can improve the ant wind load ability of photovoltaic bracket.Overall weight is light, can meet upper people's cement roof dead load requirement and also can meet non-upper people roof dead load requirement, applied range.
This case adopts a kind of New-support of combining with spoiler of support, handsome in appearance, can Assembling, and facilitate site operation, can not break the original watertight composition of ring roofing, cost is low.
