[0001] The utility model relates to the technical field of sound insulation walls beside roads, in particular to a photovoltaic sound insulation wall. Background Art

[0002] At present, the noise pollution caused by public transportation is being paid more and more attention. The existing method for this noise pollution is to use a sound insulation wall to achieve noise reduction. The existing sound insulation walls include concrete sound insulation walls, metal sound insulation walls, fiberglass reinforced plastic sound insulation walls, and photovoltaic sound insulation walls.

[0003] The existing photovoltaic sound insulation wall directly uses photovoltaic modules as part of the sound insulation wall panel, which not only has the functions of highway traffic isolation and noise attenuation, but also has the function of solar power generation, providing electrical energy for public facilities such as cameras and warnings on the installation section, which is particularly important for sections of highways where power supply is inconvenient.

[0004] However, since the existing photovoltaic sound insulation wall is directly used as the sound insulation wall panel, for example, a photovoltaic wall for a highway system disclosed in the prior art CN211171686U. When a traffic accident occurs and a vehicle hits the upper part of the photovoltaic wall, it will cause large-area damage to the photovoltaic modules, resulting in relatively large economic losses. Moreover, since the photovoltaic modules are charged, during the power generation process of the photovoltaic modules during the day, if a major traffic accident occurs, it will pose a danger of secondary electric shock to the accident vehicle and personnel. In addition, the sound insulation wall is arranged perpendicular to the ground, so that the area of the photovoltaic modules receiving sunlight is small, and the photovoltaic power generation efficiency is low.

[0005] Therefore, it can be seen that the above-mentioned existing photovoltaic sound insulation walls obviously still have inconveniences and defects in terms of structure, method and use, and need to be further improved urgently. How to create a new photovoltaic sound insulation wall that uses prefabricated sound insulation panels to install photovoltaic modules, which not only meets the sound insulation and anti-collision requirements of the sound insulation wall, but also meets the photovoltaic power generation requirements, avoids damage and secondary injuries caused by traffic accidents, and has high power generation efficiency, and the solar photovoltaic modules have self-cleaning functions, has become an extremely urgent improvement goal in the current industry.

Figure 4 As shown, the support assembly includes an upper fixed beam 3, a lower fixed beam 4, an inclined beam 5 and a purlin 6. The length of the upper fixed beam 3 is less than that of the lower fixed beam 4, and the upper fixed beam 3 and the lower fixed beam 4 are both vertically fixed on the outer facade of the sound insulation board 1. One side of the inclined beam 5 connects the free ends of the upper fixed beam 3 and the lower fixed beam 4. Since the length of the upper fixed beam 3 is less than that of the lower fixed beam 4, the inclined beam 5 is obliquely arranged relative to the sound insulation board 1, and the effective inclination is 30-60 degrees. The sound insulation board 1 is provided with a plurality of inclined beams 5 arranged side by side. The purlin 6 is transversely fixed on the inclined beam 5, and at least two parallel purlins 6 are arranged on the inclined beams 5 arranged side by side. The two sides of the photovoltaic module 2 are fixed to the purlin 6 by a pressing block 7. The function of the purlin 6 is to be able to better and more flexibly install the photovoltaic module 2, without being affected by the spacing of the inclined beams 5. In this way, the inclination of the inclined beam 5 can be determined according to the actual application environment, and then the inclination of the photovoltaic module 2 can be determined, so as to maximize the power generation efficiency of the photovoltaic module 2 and meet the power demand of the power facilities beside the road.

[0031] Of course, the photovoltaic assembly 2 can also be directly fixed on the inclined beam 5, which is simpler and requires fewer parts.

One of the top corners of the rotating connector 8 is hinged to the free ends of the upper fixed beam 3 and the lower fixed beam 4, and the bottom side of the rotating connector opposite to the top corner is fixedly connected to the inclined beam 5. In this way, the rotating connector 8 can facilitate the installation of the inclined beam 5, adapt to different installation slopes, and is flexible and convenient.

[0033] In addition, the support assembly further includes an intermediate support beam 9, and the intermediate support beam 9 serves to further support and fix the inclined beam 5. Specifically, one end of the intermediate support beam 9 is rotatably connected to one end of the lower fixed beam 4 close to the sound insulation board 1, and the other end of the intermediate support beam 9 is fixedly connected to the inclined beam 5. Of course, rotating connectors 8 hinged to the ends thereof may be provided at both ends of the intermediate support beam 9, which is more convenient for construction operations.

[0034] Refer to the attached Figure 4 As shown, the sound insulation wall 10 is made of concrete. For example, the sound insulation board 1 is made of precast concrete slabs, and a number of embedded parts 11 for fixing the upper fixed beam 3 and the lower fixed beam 4 are embedded in the precast concrete slabs. The protruding ends of the embedded parts 11 have threads, which is convenient for the installation and fixation of the fixed beams.

[0035] Moreover, the sound insulation wall 10 includes a concrete base and columns 12 provided on the concrete base, and the sound insulation board 1 is fixed to the columns 12. Preferably, the columns 12 adopt an I-shaped structure with double-sided grooves, and the double-sided grooves are respectively used for inserting the sides of the sound insulation board 1. This installation method is simple and convenient, and has good sound insulation effect.
