Detailed Description
The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.
Referring to fig. 1, the implementation contents of the embodiment of the present utility model include:
the toughened frame for the solar photovoltaic module comprises a whole stainless steel plate, wherein the stainless steel plate is continuously bent into eight sections, namely a first bending part 1, a second bending part 2, a third bending part 3, a fourth bending part 4, a fifth bending part 5, a sixth bending part 6, a seventh bending part 7 and an eighth bending part 8: the first bending part 1 and the second bending part 2 are mutually perpendicular, the first bending part 1 forms the panel outer pressing edge of the toughened frame for the solar photovoltaic module, the second bending part 2 forms the outer frame surface of the toughened frame for the solar photovoltaic module, the third bending part 3 is inwards bent and overlapped with the fourth bending part 4 to form the back plate pressing edge, the fifth bending part 5 is attached to the inner side of the second bending part 2, the sixth bending part 6 is mutually perpendicular to the fifth bending part 5, the back plate pressing edge, the fifth bending part 5 and the sixth bending part 6 form the back plate mounting groove 11 together, the seventh bending part 7 is perpendicular to the sixth bending part 6, the seventh bending part 7, the sixth bending part 6 and a part of the first bending part 1 and the second bending part 2 form the buffer connection cavity 10, the eighth bending part 8 is mutually perpendicular to the seventh bending part 7 and attached to the inner side of the first bending part 1, and the top end of the eighth bending part 8 is connected with the top end of the first bending part 1 in a rolling mode.
In practical implementation, the included angle between the back plate pressing edge and the second bending part 2 is generally 75-85 degrees, and the value is generally 80 degrees, so that the back plate is pressed in the back plate mounting groove 11 by using the elasticity of the back plate pressing edge to prevent loosening.
In actual production, the width of the blank holder is 8-12 mm, the width of the sixth bending part 6 is 8-12 mm, and the width of the seventh bending part 7 is 15-25 mm. One practical implementation data is as follows: the width of the backboard reinforcement pressing plate is 10mm, the sixth bending part 6 is 9.8mm, and the seventh bending part 7 is 19.8mm. The reason for adopting the data is that the buffer connection cavity 10 is formed by the sixth bending part 6 and the seventh bending part 7 and the corresponding parts of the first bending part 1 and the second bending part 2, so that the width of the seventh bending part 7 is related to the thickness of the photovoltaic panel, and the width of the pressing edge of the back plate is close to the sixth bending part 6, so that the panel is conveniently placed into the panel mounting groove 12 formed by the seventh bending part 7 and the eighth bending part 8 together during mounting, and then the back plate is mounted.
In practical implementation, the top of the eighth bending part 8 and the top of the first bending part 1 are rolled up to form a panel pressing head 9 towards one side of the eighth bending part 8, the panel pressing head 9 can utilize a pressing edge formed by the eighth bending part 8 and the first bending part 1 to provide certain pressure for the photovoltaic panel, the stability of panel installation is improved, the rolling surface width of the panel pressing head 9 is 10-15 mm, and is generally preferably 12mm, so that the panel pressing head with larger width can avoid too large pressure at the pressing position and damage the glass surface on the panel.
The thickness of the stainless steel plate is 0.5-0.8 mm, the stainless steel plate with the thickness of 0.6mm is generally selected in actual production, the mechanical strength of the telephone with the thickness of the plate is insufficient, the telephone with the thickness of the plate is difficult to process, the weight is increased, and the production cost is increased.
The surface of the stainless steel plate is provided with an anti-corrosion coating, the anti-corrosion coating is a magnesium-aluminum-zinc ternary alloy coating, the coating contains A l 55%wt, S i 1.5.5%wt and Zn, and about 1.2.2%Mg element is added into the coating on the basis, so that the obtained steel plate has good surface corrosion resistance, and the edge cutting position has excellent corrosion resistance, thereby being beneficial to long-term outdoor use.
