Description

TECHNICAL FIELD

[0001] The application relates to the field of new energy photovoltaics, and particularly relates to a photovoltaic sand control device combining biological mineralization soil mulching and plants. BACKGROUND

[0002] The northwest region of China is rich in light resources, and has various landforms. The photovoltaic industry develops in a strong manner. The desert and Gobi in the northwest region are rich in solar resources and have relatively low land costs, so that the desert and Gobi photovoltaic power station can generate high economic benefits. However, the thermal imbalance in the desert and the large air pressure gradient cause the wind power formed thereby to cause wind erosion and drifting sand and other adverse natural phenomena in the desert region. I. Due to the "narrow tube" effect, the wind speed at the bottom of the photovoltaic panel is lifted to form an erosion groove. The soil around the photovoltaic pile foundation is eroded by the airflow and exposed to the ground. Under the wind pressure load in the desert environment, the photovoltaic pile foundation is prone to instability, which causes the photovoltaic power generation equipment to overturn. II. Due to the reduction of the wind speed gradient in the environmental flow field near the panel surface, the sand material carried in the wind-sand flow is deposited on the photovoltaic panel surface, causing the panel surface to be sand-covered. The sand-covered panel reduces the light transmittance of the photovoltaic panel, increases the temperature of the photovoltaic panel, and reduces the conversion efficiency of the photovoltaic component. According to research, the power efficiency of photovoltaic panels with different installation angles under field conditions is less than 80.6% on average after 12 months of continuous sand accumulation, and the minimum is only 70%. In view of the sand accumulation problem of the photovoltaic panel in normal operation, the current solution is to regularly clean the panel surface. However, the annual rainfall in the desert and Gobi region is small, and water resources are scarce. The operation and maintenance of the photovoltaic industry are limited. III. Due to the impact and abrasion of sand particles in the wind-sand flow on the photovoltaic panel surface, the service life of the photovoltaic panel is seriously affected, and the photovoltaic industry needs to invest additional repair costs every year. Therefore, the key to solving the problem is to prevent the sand particles from starting and reduce the wind speed in the area near the photovoltaic power station, The research and demonstration of the integrated water and soil holding comprehensive management technology of the internal water-saving and erosion control coordinated "solid-transportation-conduction" integration, focuses on the research and development of the rapid prevention and control and stable maintenance of the quality improvement and efficiency increase technology of the peripheral drifting sand of the sand area photovoltaic power station. The research and demonstration of the integrated water and soil holding comprehensive management technology of the internal water-saving and erosion control coordinated "solid-transportation-conduction" integration. Around the carbon sequestration capacity and potential of photovoltaic energy projects, the service value improvement research of the desert ecological region is carried out.

[0003] The photovoltaic panel has the functions of shading and rainwater collection. Therefore, the number of species and the species diversity in the desert and Gobi power station are higher than those outside the power station, and the vegetation restoration effect in the photovoltaic power station is more obvious. However, the plants are prone to die in the early stage of growth due to the harsh environment in the sand region. The biological rock-soil technology can provide a mulch layer to protect the plants during the growth process and reduce the adverse effects of wind erosion on plant growth. The greenery under the panel cooperates with the biological mineralization mulch layer to effectively control the wind erosion hazards in the photovoltaic area.

[0004] The desert area is provided with a photovoltaic power generation field with windproof and sand fixation functions. A detached vortex is formed at the back of the photovoltaic panel, i.e. a closed low-speed area is formed at a certain distance from the back of the photovoltaic panel, which causes sand accumulation at the back of the photovoltaic panel. The unstable sand accumulation area at the back of the photovoltaic panel can be fixed by using a biological rock-soil technology. The biological rock-soil technology and the photovoltaic array can be organically combined to optimize the windproof and sand fixation effect in the desert area.

[0005] In addition, in order to save manpower and material resources, the accumulated sand on the panel surface is cleaned while the film under the panel is greened. The existence of the photovoltaic panel base will affect the film and cleaning effect.
