Abstract
The utility model provides an aluminum alloy profile for the frame of a solar photovoltaic cell, characterized in that the asymmetric cross section structure of the aluminum alloy profile is composed of a top edge (1), a side edge (2), a middle edge (3), a reinforced edge (5), a slot (6), and a convex rib (7). In the utility model, a reinforced asymmetric cross section structure is adopted, namely the edge of the slot on the upper portion of the profile is shorter than the bottom edge on the lower portion of the profile, and the side edge of the profile is additionally added with the reinforced edge connecting the lower edge of the slot with the bottom edge of the profile, and parallel to the side edge so as to increase the bearing strength of the profile, thus overcoming the problems of large weight per unit length, high cost and small bearing strength, which are existed in the prior art. The aluminum alloy profile for the frame of a solar photovoltaic cell enables the frame of the solar photovoltaic cell to have a lightened weight per unit length, a lowered cost, and an improved bearing strength.

Technical field
The utility model relates to a kind of aluminium alloy extrusions, specifically is meant the aluminium alloy extrusions that is used to make a kind of solar-energy photo-voltaic cell framework of fixing the framework that carries the solar-energy photo-voltaic cell group.
Background technology
The aluminium alloy extrusions that prior art is used to make the solar-energy photo-voltaic cell framework follows the symmetrical section structure of door and window aluminium alloy extrusions; The aluminum alloy doors and windows that are different from vertical installation are because solar-energy photo-voltaic cell group plate is to tilt or the horizontal mode installation, in order to satisfy bearing capacity; Must not increase wall thickness then to improve bearing strength; Simultaneously also strengthened cost, therefore, there are the problems and shortcomings that unit weight is big, cost is high, bearing strength is low in prior art.
Summary of the invention
Problems and shortcomings to above-mentioned prior art existence; The utility model adopts the unsymmetrical section structure that strengthens; That is, the length of side of section bar top draw-in groove is shorter than the length of side on base, section bar bottom, sets up one in the side edge of section bar and connects draw-in groove bottom and section bar base and the stiffened edge parallel with side; Technical scheme with the bearing strength of reinforcing profile; A kind of aluminium alloy extrusions of solar-energy photo-voltaic cell framework is provided, is intended to make the solar-energy photo-voltaic cell framework, reach the purpose that alleviates unit weight, reduces cost, improves bearing strength through asymmetric enhancing structure.
The purpose of the utility model is achieved in that a kind of aluminium alloy extrusions of solar-energy photo-voltaic cell framework, for being provided with the asymmetrical cross-section structure, by drawing molded aluminum alloy matter elongated member material; Described asymmetrical cross-section structure is made up of top margin, base, side, middle limit, stiffened edge, draw-in groove, convex tendon; End cross section with the aluminium alloy extrusions of said solar-energy photo-voltaic cell framework carries out structrual description; Described base is the lamellar body of level; The left side on base is provided with the side of lamellar body vertically upward; The top of said side is provided with the top margin of level lamellar body to the right, and top the right of said top margin is provided with downward-sloping slope, and the below of top margin is provided with parallel with top margin and at a distance of the middle limit of the lamellar body in 6.75 millimeters gaps; The left end on limit links to each other with the right side of side in said, and the rectangular channel shape zone that is surrounded by top margin, side, middle limit is called draw-in groove;
The equal in length on top margin and middle limit, the length that is shorter in length than said base on top margin, middle limit; The following centre on limit is provided with the stiffened edge of lamellar body vertically downward in said, and the lower end of said stiffened edge links to each other with the top of base; Be arranged in the top of the rectangle hollow out zone that surrounds by limit, stiffened edge, base sealing and below be respectively equipped with the convex tendon of protrusion.
Structural principle
Because the length that is shorter in length than said base on top margin, middle limit; Therefore constituted the asymmetric up-down structure of the cross section of this section bar; Simultaneously owing to being provided with the average wall thickness that bearing strength that stiffened edge and convex tendon improved this section bar need not to increase section bar; Thereby alleviated the unit weight of section bar, reduced material cost.
Above-mentioned; The utility model adopts the unsymmetrical section structure that strengthens; That is, the length of side of section bar top draw-in groove is shorter than the length of side on base, section bar bottom, sets up one in the side edge of section bar and connects draw-in groove bottom and section bar base and the stiffened edge parallel with side; Technical scheme with the bearing strength of reinforcing profile; Overcome prior art and had the problems and shortcomings that unit weight is big, cost is high, bearing strength is low, the aluminium alloy extrusions of a kind of solar-energy photo-voltaic cell framework that is provided makes the solar-energy photo-voltaic cell framework reach the purpose that alleviates unit weight, reduces cost, improves bearing strength through asymmetric enhancing structure.
