Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving sound barriers, and in particular to a combined solar photovoltaic sound barrier and an installation method thereof. Background Art

[0002] At present, the most direct and effective means of controlling road traffic noise is to control the noise of the vehicle itself, so as to achieve the purpose of controlling road traffic noise from the source of sound. However, the control and reduction of noise from the vehicle itself is closely related to the current status and level of the automobile industry. According to research, every reduction of 1 decibel of noise requires extremely high R&D funds and long-term R&D, making it impossible to achieve and complete noise reduction in the short term. Therefore, controlling noise from the transmission path has become an effective means of controlling road traffic noise.

[0003] Controlling noise from the transmission path is to build a sound barrier, which can be used to isolate the noise receiver from the noise source to reduce noise. At present, the sound barrier is made of soil, bricks, concrete, wood, metal and resin, which only has the function of sound insulation, resulting in a single function of the installed sound barrier.

[0004] In view of this, those skilled in the art have considered using combined combination technology to combine and install solar photovoltaic panels with sound barriers, realize the combination of solar photovoltaic power generation technology and sound barriers, and form a sound barrier with photovoltaic power generation function. For example: Patent No. 2019202881191 discloses a photovoltaic module, the bottom surface of which is fixed to the front end of the column, and the front and rear sides of the middle of the column are respectively installed with rod-shaped front supports and rear supports, the top ends of the front supports and rear supports are fixed to the bottom surface of the photovoltaic module, and the bottom end of the column is installed on the bottom plate through an azimuth adjustment flange, and the bottom plate is fixed to the sound barrier foundation assembly through bolts, nuts and gaskets; the orientation of the photovoltaic module is changed by adjusting the azimuth flange, which greatly improves the solar radiation resources received by the surface of the photovoltaic module. Another example: Patent No. 2015202980771 discloses a sound barrier unit including a base and columns arranged at intervals on the base, at least one sound barrier unit with a double-sided solar photovoltaic module is arranged between adjacent columns, the four sides of the double-sided solar photovoltaic module are wrapped with a fixed frame, and the fixed frames on the left and right sides are provided with elastic elements. The double-sided solar photovoltaic module is supported in the vertical slot of the column by the elastic element, so that the direct sunlight and the ground reflected sunlight are used to generate electricity, so that the utilization rate of sunlight is greatly increased and the utilization is maximized; at the same time, the double-sided solar module can absorb light in all directions, so that the installation angle of the sound barrier is not limited. However, the structural design of the solar photovoltaic sound barrier in the above-mentioned prior art is unreasonable, so that when it is installed on both sides of the road, it is difficult to isolate the road traffic noise or when it is isolated from the road traffic noise, it leads to a significantly lower utilization rate of the solar photovoltaic panel and a higher cost, which makes it difficult to use it on a large scale in terms of road traffic noise isolation.

[0005] Based on this, some researchers in the prior art have conducted research on solar photovoltaic sound barriers suitable for installation on both sides of the road. For example, patent application No. 201610438898X discloses columns installed on both sides of the road, noise-absorbing sound-absorbing panels are installed between adjacent columns, triangular brackets are installed on the columns, and solar photovoltaic panels are installed on both sides of the triangular brackets. However, there are problems in this technology: the installation angle of the solar photovoltaic panel is limited by the angle of the triangular bracket itself, so that after installation, the inclination angle of the solar photovoltaic panel cannot be adjusted as needed, resulting in the solar photovoltaic sound barriers installed on both sides of the road being difficult to adjust according to seasonal conditions and utilize sunlight, resulting in the solar photovoltaic panel utilization rate changing with the seasons; at the same time, due to the limitation of the fixed structure of the triangular bracket, the installation method is fixed, which makes the installation difficult.
