Description

TECHNICAL FIELD

[0002] Due to its unique geographical and climatic conditions, sandstorms frequently occur in the Shaguo Desert region, causing serious damage to transportation infrastructure such as highways and railways. The invasion of sandstorms not only leads to sand burial and wear of roadbeds and tracks, but also damages signal equipment and other infrastructure along highways and railways, posing a serious threat to traffic safety and increasing maintenance costs. In the northwest region, frequent sandstorms have become an important factor restricting the long-term stable operation of traffic lines. In order to alleviate the damage of sandstorms to traffic lines, existing sand prevention measures such as wind barriers, sand barriers, sand barriers, and wind and dust control nets can effectively reduce the direct impact of wind and sand flow on roadbeds, but also have certain limitations. Traditional sand prevention facilities focus on physical interception and lack long-term support for ecological environment improvement and restoration, and cannot fundamentally solve the problem of desertification.

[0003] In recent years, with the rapid development of photovoltaic power generation technology, photovoltaic panels have been introduced into the field of sand prevention and control, forming a new model of "photovoltaic sand control". This model not only reduces wind speed through photovoltaic panels and reduces wind and sand erosion of the ground, but also provides energy and economic support for ecological restoration. However, in the process of using the "photovoltaic sand control" model to protect the roadbed of the traffic line, the regulation of the plant growth environment is a major problem, and the water source in the Shaguo Desert region is extremely scarce, which requires scheduling to regulate soil humidity, greatly increasing the operation and maintenance cost, and how to comprehensively utilize water resources, avoid water resource waste, effectively save water resources and energy is also a problem to be solved by the prior art.
