Description

Lightweight photovoltaic bracket and photovoltaic plant

Technical field

The utility model is related to photovoltaic plant technology field, more particularly, to a kind of lightweight photovoltaic bracket.This practicality is new Type further relates to a kind of photovoltaic plant with above-mentioned lightweight photovoltaic bracket.

Background technology

Solar photovoltaic generation system refers to using solar energy, using the special materials electronics such as crystal silicon plate, inverter The power generation system of element composition, the photovoltaic generating system for being connected with power grid and transmitting electric power to power grid.Solar energy power generating system System mainly includes solar cell array, accumulator group, charging-discharging controller, inverter, AC power distribution cabinet/AC distribution panel and solar tracking control System processed.Worldwide energy crisis promotes the fast development of New Energy Industry, and solar energy be it is various give birth to it is most heavy in the energy The basic power source wanted, the application range of solar photovoltaic generation system was more and more extensive in recent years, and having in many industries should With.

The Generation Rate for improving solar photovoltaic generation system carries out in terms of two, first, improving the conversion effect of sunlight Rate, second is that reducing the energy consumed of electricity generation system in itself.Improving the design of the transformation efficiency use of sunlight is：As far as possible The incident ray of the sun is allowed to remain vertical with the plate face of the solar panels in photovoltaic module.But the sunlight in one day enters The angle of ray is continually changing, it is therefore desirable to the position of solar panels is constantly adjusted to ensure preferably to follow sunlight, The namely hunting gear of solar panels.And the resistance that the hunting gear of solar panels necessarily overcomes is essentially from solar energy Plate and its photovoltaic bracket of support.Therefore the weight for reducing photovoltaic bracket is conducive to improve the transformation efficiency of sunlight.And it reduces The weight of photovoltaic bracket is equally beneficial for reducing the energy consumed of electricity generation system in itself.It can be seen that it is necessary to take measures to mitigate The weight of photovoltaic bracket.

In addition, it is to the design requirement of photovoltaic bracket：(1) structure must be solid and reliable, can bear such as atmospheric corrosion, wind lotus It carries and other external effects.(2) installation cost is low, reaches maximum using effect as far as possible with minimum installation cost.(3) tie up It is low to repair cost of upkeep.It can accomplish non-maintaining or relatively low maintenance cost as far as possible.

Mitigating the means of the weight of photovoltaic bracket mainly includes 1. changing material, 2. removes material in non-bearing position, with And 3. redesign whole structure, that is, change the structure and position relationship of rod piece between structure.1. change in above-mentioned measure Material may be subject to following limitation：The material of photovoltaic bracket selects high-wearing feature good as far as possible, to resist wind-force snow load and its Its corrosiveness.In addition, good economy performance is also selected, to promote in a wider context.Use more at present is 2. non- Carrying position removal material, but the limited configurations that can so operate, therefore the weight mitigated is also limited.As it can be seen that it 3. weighs Effect that the whole structure of new design is obtained when mitigating the weight of photovoltaic bracket is more preferable, the scope of application is wider.

Since the area of solar panel is directly related to the generated energy of photovoltaic plant.In order to increase solar panel Area, the splicing of way usual plurality of plates.At the same time, solar panel is seldom directly to be connected with ground, usually Photovoltaic bracket is provided in, therefore photovoltaic bracket is generally also multiple.This is between solar panel and photovoltaic bracket Connection mode can be that a solar panel corresponds to a photovoltaic bracket, but the total tune so after assembling is not It is good, and work progress is cumbersome.Based on drawbacks described above, those skilled in the art expect setting a larger stent, by the polylith sun Energy solar panel is all connected on the stent of this increasing.But the stability of large-scale stent is bad, polylith solar panel exists Connection on large-scale stent is insecure.

Based on drawbacks described above, those skilled in the art expect only increasing the size in a direction of large-scale stent, another without increasing The size in one direction is to improve the stability of stent.It is to grow solar panel of 2 meters of width as 1.5 meters of one piece of rectangle Example if a photovoltaic bracket fixes a solar panel, is led on photovoltaic bracket for fixing the position of solar panel at this time Often it is rectangular shaped rim, four sides of rectangular shaped rim and solar panel are correspondingly connected with, at this time photovoltaic bracket and solar cell Plate is overall structure, as long as the bonding strength of the junction of the two is high, what solar panel can just be stablized is fixed in photovoltaic On stent.But if further increasing the area of the rectangle frame of photovoltaic bracket at this time and connecting multiple plates on it, then every It also needs to install connection structure additional between a solar panel, at this time if there is wind is blown, all solar panels are together It is very easy to come off from the big rectangular frame of area after deformation.It to solve the above-mentioned problems, can on large-scale photovoltaic bracket Frame structure to be changed to the structure of plate, after the solar panel connection of the photovoltaic bracket and plate profile structure of plate profile structure, too The deflection of positive energy solar panel can inhibit a part by photovoltaic bracket, that is, be equivalent to the thickness for having thickeied solar panel And intensity, but such setting can increase the weight of photovoltaic bracket.Since current photovoltaic bracket is typically provided with servo-actuated dress It puts, hunting gear can make solar panels with sunlight rotational of beam, therefore the weight of photovoltaic bracket increases, and hunting gear is born Carrying capacity is increased by.Based on drawbacks described above, those skilled in the art expect only increasing the size in a direction of large-scale stent, that is, increase Add the length of photovoltaic bracket, reduce the width of photovoltaic bracket.In parallel, more than two photovoltaic branch using more than two photovoltaic brackets Frame is provided commonly for one piece of solar panels of connection.But such structure is still present with the problem of cumbersome for installation, is servo-actuated dress in addition When putting while adjusting the angle of multiple stents, it is complicated, control process it is cumbersome.

To sum up, how to provide that a kind of total quality is light, and the photovoltaic bracket that structural strength is high, rigidity is high, stability is good, It is those skilled in the art's urgent problem to be solved.Based on this, the utility model provides a kind of lightweight photovoltaic bracket and light Overhead utility is to solve the technical issues of above-mentioned.
