Description

Photovoltaic assembly structure for support for roof erection

Technical Field

The invention belongs to the technical field of photovoltaic supports, and particularly relates to an assembly structure for a photovoltaic support for building a roof.

Background

The application of the solar support system in solar panel support has the advantages of simple production and installation; the solar panel can also move flexibly according to the sun rays and seasons; just like when first installation, the inclined plane of every solar panel all can be through removing the fastener, and the adjustment inclined plane is in order to adapt to the different angles of light, makes solar panel fix in the appointed position accurately through retightening.

At present, the application of the solar photovoltaic panel is extremely wide, the solar photovoltaic panel is not limited to heating of daily water supply of a family, more and more industrial production and power supply of public facilities need to use the solar photovoltaic panel, the solar photovoltaic panel is difficult to be directly connected and fixed with an installation interface, so the installation is inconvenient, the adjustment in the future is extremely difficult, a photovoltaic bracket is generally needed to be used for installing and fixing the photovoltaic panel, although the installation bracket of the existing solar photovoltaic panel can also meet the daily installation and fixation, the included angle between the solar irradiation light and the contact surface of the photovoltaic panel is different due to different heights in different seasons in the actual use, the conversion efficiency of energy can be maximized when the solar irradiation light forms a right angle with the surface of the photovoltaic panel, and the elevation angle of the photovoltaic panel needs to be adjusted according to different solar heights in different seasons, however, most of the existing photovoltaic panel bracket mounting, fixing and assembling devices need to be used for adjusting the angle of the photovoltaic panel in a mode of locking the photovoltaic panel by unscrewing all bolts, so that the photovoltaic panel is easy to loosen and damage due to lack of bolt fixation after the bolts are disassembled.

Moreover, when the current assembly structure of photovoltaic board installing support adjusts the photovoltaic board angle of elevation, not only need unscrew all bolts, in addition after the angle modulation is accomplished, still need in proper order with the bolt of unscrewing once more screw, then can increase staff's the operation degree of difficulty like this, reduce its work efficiency, the bolt hole site of precessing again needs to be calibrated in proper order moreover to further increase the loaded down with trivial details degree of installation.

Meanwhile, most of the existing photovoltaic panel mounting and fixing support devices are structurally fixed, and need to be fixed on a mounting plane through bolts, and later-stage use of the photovoltaic panel often needs to replace conversion capacity of the photovoltaic panel according to actual strength, so that different light energy conversion efficiencies are met, and the existing photovoltaic panel mounting and fixing support devices do not have functions suitable for different photovoltaic panel sizes due to structural fixation, so that a novel photovoltaic panel mounting and fixing support structure which is wide in application range and convenient to adjust needs to be researched and developed.
