There are no relevant cases in the existing technology for photovoltaic sound barrier systems in the field of rail transit, especially for the arc segment and broken line segment on the top of the closed sound barrier. The overall weight of the existing photovoltaic modules is heavy, and they are generally only used for flat installation. There are no matching products for the angled surface and the curved surface. The connection method of the existing photovoltaic modules is difficult to meet the connection reliability under the vibration conditions of rail transit trains.

[0052] The working principle of the above technical solution is: install purlins 3 on two adjacent door-type frames 4, and install and fix the photovoltaic sound barrier integrated component 1 on the purlins 3 through the connecting component 2, thereby completing the installation and fixation of the photovoltaic sound barrier integrated component 1.

In addition, the adapter can also be installed at the angle surface, and the adaptability is strong;

[0053] The photovoltaic sound barrier integrated component 1 is light in overall weight, with an average mass per unit area not exceeding 17kg / m2, with little increase in external load, and can be installed on existing structures.

[0054] Embodiment 2

[0055] like Figure 1-Figure 22 As shown, the photovoltaic sound barrier integrated component 1 includes a photovoltaic sound barrier plate 102, which is installed in a photovoltaic component frame 101, and the photovoltaic component frame 101 is fixedly connected to the purlin 3 through a connecting component 2, and an EPDM rubber strip 6 is provided between two adjacent photovoltaic component frames 101;

[0056] The photovoltaic sound barrier plate 102 is composed of a photovoltaic glass layer, a battery layer, a photovoltaic glass layer and an organic backplane layer from the outside to the inside, and a glue layer is provided between two adjacent layers;

[0057] The working principle of the above technical solution is: the double-layer photovoltaic glass plus organic back panel design replaces the traditional sound barrier screen, and adds power generation function on the basis of sound insulation or sound absorption of the traditional sound barrier;

[0058] The double-layer photovoltaic glass faces the outside of the sound barrier, and the organic backplane faces the inside of the sound barrier. The two deform together and work together;

[0059] The double-layer photovoltaic glass, organic back sheet and photovoltaic module frame 101 jointly bear the wind load and impact load, which greatly improves the impact resistance of the photovoltaic sound barrier integrated component 1 without increasing the thickness and weight, and ensures the lightweight and operational safety requirements of the subway photovoltaic sound barrier;

[0062] Embodiment 3

[0063] like Figure 1-Figure 22 As shown, connecting plates 5 are fixed on both sides of the door-shaped frame 4, and the connecting plates 5 are fixedly connected to the purlin 3 by anti-drop bolts 7;

[0064] The working principle of the above technical solution is: a long groove is provided on the connecting plate 5, and the anti-detachment bolt 7 passes through the long groove on the connecting plate 5 and is fixed on the purlin 3. The purlin 3 can be pulled outward or inward, thereby changing the position of the purlin 3 relative to the door-type frame 4, and changing the position of the anti-detachment bolt 7 in the long groove. After the purlin 3 is adjusted, the anti-detachment bolt 7 is locked to fix the connecting plate 5 and the purlin 3. By fine-tuning the position of the purlin 3, the position and angle of the purlin 3 are more suitable for fitting on the inner side of the photovoltaic module frame 101.

[0065] Embodiment 4

The other side of the edge pressing block 1206 is against the photovoltaic sound barrier board 102. The photovoltaic assembly frame 101 and the sound insulation board 11 are fixed to the U-shaped steel groove 2 1201 by bolts 3 1205.

[0068] The working principle of the above technical solution: Due to the different installation scenarios of the photovoltaic sound barrier integrated component 1, some are installed on curved surfaces, some are installed on flat surfaces, etc., the distance and angle between the photovoltaic sound barrier integrated component 1 and the purlin 3 are also different. The distance and angle between the photovoltaic sound barrier integrated component 1 and the purlin 3 can be measured on site, and the welding position of the U-shaped steel groove 201 and the angle steel 208 can be adjusted so that the angle steel 208 can be fixed on the purlin 3. The U-shaped steel groove 201 can be fixed to the photovoltaic sound barrier integrated component 1. When the train passes under the door frame 4, the door frame 4 has a certain vibration.

The other end of the anti-slip T-shaped bolt 205 is against the aluminum alloy pressing block 9, and the two ends of the aluminum alloy pressing block 9 are respectively pressed on the two adjacent photovoltaic module frames 101;

[0074] The working principle of the above technical solution is: the bolt cap at the lower end of the anti-slip T-bolt 205 is long and strip-shaped, and the upper opening of the basin-shaped steel groove 209 is also long and strip-shaped. After the bolt cap at the lower end of the anti-slip T-bolt 205 is inserted into the basin-shaped steel groove 209, the anti-slip T-bolt 205 is rotated 90 degrees, and the bolt cap at the lower end of the anti-slip T-bolt 205 can be clamped in the basin-shaped steel groove 209, thereby increasing the connection stability between the anti-slip T-bolt 205 and the U-shaped steel groove 201.
