Description

High-efficient photovoltaic sound barrier top device

Technical Field

The utility model relates to a high-efficient photovoltaic sound barrier top device.

Background

With the development of urbanization in China, road traffic brings convenience to the lives of residents and also causes serious noise influence. Sound barriers are one of the most common noise control measures, and are usually installed on both sides of a road or an overhead bridge in an upright or closed/semi-closed structure. The traditional sound barrier only plays a role in noise reduction and has a relatively single function.

Solar energy is the most important new energy type. The photovoltaic cell panel converts solar energy into electric energy based on a photoelectric effect, and the power generation efficiency of the photovoltaic cell panel is greatly influenced by the environment. The relative orientation of the photovoltaic panel to the sun is an important influencing factor, theoretically having the greatest efficiency of power generation in the case of direct sunlight. When the photovoltaic panel works, heat is generated, the temperature of the noise component rises, the generating efficiency is reduced due to the rise of the temperature, and the peak power loss of the photovoltaic panel is about 0.14% when the temperature is increased by 1 ℃. Local overheating can also damage the photovoltaic module, affecting the service life of the photovoltaic panel. Heat dissipation of the assembly is a problem that must be addressed.

The sound barrier is laid out along the road, has a large distribution area in a city, is less shielded by buildings, and has good light energy utilization conditions. The combination of photovoltaic power generation systems and sound barriers is a new development direction.

At present, a conventional solar photovoltaic barrier generally takes a photovoltaic module as a part of a barrier body, and is vertically arranged in the middle section of the barrier. For example, the CN 208733486U is a folding arm type photovoltaic sound barrier, which adopts transparent glass fiber reinforced plastic to clamp a photovoltaic cell panel as a middle screen body. The photovoltaic modules of such structural barriers are only passively oriented to follow the course of the road. If the photovoltaic cell panel with one side receiving light is adopted, only one side of the light energy of the roads in the south-north direction can be effectively utilized, and the two sides of the roads in the east-west direction cannot be effectively utilized. If the photovoltaic cell panel with light receiving at two sides is adopted, although the power generation efficiency of the roads in the south and north directions can be improved, the problem of the east and west directions is still not solved, and the cost is increased. The photovoltaic cell board is arranged perpendicularly, and when solar altitude angle was the highest at noon, the orientation angle was minimum on the contrary, and angle efficiency loss is great. In addition, when the vehicle runs on the road, the screen body can be damaged.

For a totally-enclosed sound barrier, a photovoltaic cell panel is installed at the top of the barrier, so that the utilization efficiency of light energy can be effectively improved, for example, "CN 209523132U is a photovoltaic grid-connected power generation system based on a viaduct totally-enclosed sound barrier", a photovoltaic module is pasted on the outer surface of the top of the totally-enclosed sound barrier. The fixed photovoltaic sound barrier has higher power generation efficiency than a vertical type photovoltaic sound barrier, but cannot adjust the position according to the sunlight intensity, and has high production cost. The CN 107675637A light intensity tracking photovoltaic sound barrier is improved, the photovoltaic panel on the top is moved by the aid of the conveyor belt device, the position of the photovoltaic panel can be moved according to the light intensity, and the laying area of the photovoltaic panel can be saved. However, the totally-enclosed sound barrier has a much lower application rate than the vertical sound barrier in cities because of its high cost. And the photovoltaic sound barrier can only be used for newly-built projects and cannot be suitable for the reconstruction of the existing sound barrier. In addition, the mode that photovoltaic cell panel pastes in the sound barrier screen body outside can reduce the heat dispersion of panel, influences the generating efficiency.

Installing an independent photovoltaic module on the top end of the vertical sound barrier is a convenient installation and popularization mode. The CN 209860855U solar photovoltaic sound barrier and the independent adjustable photovoltaic module thereof adopt a flange plate to install an independent photovoltaic plate component on an upright post of the sound barrier, adjust an azimuth angle through a waist-shaped adjusting hole on the flange plate, and adjust an elevation angle of a photovoltaic plate through front and rear supports. The device can only predetermine position and altitude angle when the installation, and the photovoltaic board becomes fixed form after the installation is accomplished. When the solar altitude changes in a day, the problem that the light energy utilization efficiency is not high exists. And when the azimuth and the trend of sound barrier move towards inconsistent, cause the photovoltaic board transversely to extend, influence the pleasing to the eye of route, have potential safety hazards such as interference driver sight.

Based on the problems, on the design of the light energy utilization type sound barrier, a more reasonable top end structure form can be adopted, the light energy utilization efficiency is improved by adopting intelligent control, and the noise reduction effect of the barrier is ensured. The production cost of the device is reduced, and the popularization value is improved.
