Such as figure 2 As shown, there are 8 brackets 2 arranged in sequence from top to bottom in the frame 4. The back surface of the bracket 2 is bonded to the inner flange 48 of the frame 4, and the left and right end faces of the bracket 2 are bonded to the inner side 49 of the frame 4. Such as Figure 7 As shown, the upper surface of the uppermost bracket 2 is bonded to the upper surface 410 inside the frame 4, and the lower surface of the lowermost bracket 2 is bonded to the lower surface 411 inside the frame 4. The upper and lower surfaces of two adjacent brackets 2 are bonded together.
[0040] Such as figure 2 As shown, the back of the frame 4 has a rectangular inner frame 46 with an inverted edge. Such as Figure 4 As shown, the front four corners of the back frame 7 are provided with four positioning posts (or right-angle irons) 73 corresponding to the in-turned rectangular inner frame 46. The back frame 7 is connected and matched with the inner flanged rectangular inner frame 46 through the positioning column 73, and is fixed together with the frame 4 (such as image 3 Shown).
[0041] Such as Figure 4 As shown, a vertical support plate 74 is provided in the center of the bottom surface of the back frame 7. A vertical fixed brace 71 is symmetrically provided on both sides of the pallet 74, and the fixed brace 71 is provided with a through hole 72 for welding (or riveting) a fixed pendant 44 (such as image 3 ).
[0042] Such as Figure 14 As shown, the front of the pallet 74 is provided with a frame cushion strip 75 having the same size as the pallet 74, and the thickness of the frame cushion strip 75 is the same as the thickness of the inner flange 48. During installation, the support plate 74 and the frame cushion strip 75 are glued together. The other surface of the frame pad 75 is bonded to the back surface of the bracket 2. A tempered glass panel 3 is installed on the front of the frame 4.
[0043] Such as Figure 13 with Figure 14 As shown, the back frame 7 passes through the fixed pendant 44 and penetrates into the through hole 51 on the dragon skeleton 5 (such as Picture 12 Shown), hung on the dragon skeleton 5 on the outer surface of the wall 8. All the joints between the frame 4, the back frame 7, the frame pad 75, the bracket 2, the tempered glass panel 3 are filled with anti-aging sealant.
[0044] Such as Picture 10 As shown, the longitudinal section of the bracket 2 is rectangular, and the inner surface of the bracket 2 is provided with a curved groove 24. The curved surface of the curved groove 24 protrudes obliquely downward. The bracket 2 body is provided with a plurality of hollow heat dissipation cavities 21. A number of heat dissipation grooves 22 arranged in the horizontal direction are evenly distributed on the surface of the arc groove 24. Grooves 23 are provided at the upper and lower ends of the arc groove 24.
[0045] Such as Picture 9 As shown, an inner arc-shaped battery sheet 1 is placed in the arc-shaped groove 24, and the upper and lower ends of the inner arc-shaped battery sheet 1 are embedded in the groove 23. The inner surface of the upper part of the bracket 2 is provided with two Led lamp slots, and an LED lamp strip 6 with a length of 2 m is arranged in the Led lamp slots. The input power on the right side of the LED strip 6 can be powered by the inner arc battery slice 1 or an external power source. The bracket 2 is integrally formed of thermoplastic elastomer. The heat dissipation cavity 21 and the heat dissipation groove 22 of the bracket 2 are used to dissipate heat when the inner arc-shaped battery sheet is working.
[0046] Such as Picture 11 As shown, the arc surface of the inner arc-shaped battery piece 1 is a part of the cylindrical curved surface taken along the axial direction, and the arc surface protrudes obliquely downward. The arc center "o" of the longitudinal section of the inner arc-shaped battery piece 1 and the lower part of the longitudinal section On the same vertical plane, the angle c between the arc center "o" of the longitudinal section of the inner arc-shaped cell 1 and the upper end of the longitudinal section and the horizon is 20°. The arc center angle of the longitudinal section of the inner arc-shaped battery piece 1 is 70°. The radius of the arc surface of the inner arc-shaped battery sheet 1 is 75 mm, and the thickness is 3-4 mm. The length of the inner arc-shaped battery piece 1 is 2m. In other beneficial embodiments, the radius of the arc surface of the inner arc-shaped battery sheet may be 20-125 mm.
[0047] Such as Picture 9 with Picture 11 As shown, ∠a is the sunlight incidence angle on the summer solstice in most parts of the country, about 75°; ∠b is the sunlight incidence angle on the vernal and autumnal equinox days, about 47.5°; ∠c is the sunlight incidence angle on the winter solstice, Approximately 20°. During the summer solstice, the middle and lower part of the inner arc cell can receive direct sunlight; on the vernal and autumnal equinox, the middle of the inner arc cell can receive direct sunlight; on the winter solstice, the top of the inner arc cell can receive the sun Direct shot. It can be seen that the inner arc-shaped solar cell of this embodiment can ensure that there is always a direct sunlight area on the solar cell throughout the year (especially from 9 a.m. to 3 p.m.), making the product’s “direct sunlight ratio” significantly greater improve.
[0048] Such as Image 6 with Figure 8 , 14 As shown, the current output connector 11 of the inner arc battery slice 1 is located on the left side of the inner arc battery slice 1, and is led out from the machined through hole 42 on the side of the frame 4, and connects electronic components in the cavity 47 on the other side of the frame The device is connected to the solar current output control device through the cable 45; when the current output connector 11 and the cable 45 are installed and connected, the surface of the side groove 47 must be installed with a cover plate 43 to protect the cable and waterproof. The LED light strip connector placed on the right side of the frame 4 has basically the same method of connecting the power input.
[0049] Such as figure 1 As shown, the output and input cables 45 respectively pass through the upper and lower surfaces of the left and right sides of the frame 4.
