Description

Technical Field

[0001] The present disclosure relates to the technical fields of sand control and photovoltaic power generation, and particularly to a container for a sand barrier and a sand barrier for a photovoltaic power station. Background Art

[0002] Photovoltaic sand control technology is a new sand control mode that combines solar photovoltaic power generation and land desertification control. Developing photovoltaic industries in deserts, gobi deserts not only has significant economic benefits, but also can effectively prevent desertification, does not occupy arable land, is beneficial to protecting arable land, and can utilize idle desert and gobi resources to generate considerable economic benefits.

[0003] The double-glass photovoltaic panels used in photovoltaic sand control can generate electricity on both sides and have a shading effect, which can reduce water evaporation and improve the growth environment of vegetation and the flatness of the land. When implementing photovoltaic sand control, according to the local geology and meteorological conditions, in the photovoltaic module array area, traditional grass grids are generally used for wind prevention and sand fixation to prevent the soil near the photovoltaic support foundation from being eroded by the wind and ultimately causing the foundation to fail, and at the same time, it can also prevent the double-glass photovoltaic panels from being buried by sand and thus reduce the power generation.

[0004] Traditional sand barrier sand fixation technology uses materials such as firewood, grass, branches, clay, pebbles, slats, nylon nets, etc. to set up square obstacles on the sand surface to control the direction, speed, and structure of sand flow, reduce wind speed, and block sand movement, so as to achieve the purpose of sand fixation and vegetation restoration. Among these traditional square sand barrier sand fixation technologies, the grass grid has the best sand fixation effect, but its service life is only 2 - 3 years. For example, a method of water collection and planting under photovoltaic panels (CN117204305) is disclosed in the prior art. This technical solution achieves the purpose of sand fixation through a plant sand barrier, but the survival of the sand barrier plants is difficult, and the reliability as a sand barrier is not high.

[0005] Degradable material sand barriers are a recently developed sand control technology that is environmentally friendly and degradable. For example, the literature named "Research on the Degradation Performance of Degradable Polylactic Acid Sand Barriers" elaborates on the performance of degradable polylactic acid sand barriers. However, through practice, although it can effectively reduce the near-surface wind speed, reduce wind erosion, and create a relatively stable and suitable environment for plant growth, due to the degradable material, the cost of degradable materials is high, and they will soon degrade and fail, thus losing the sand fixation effect.
