Wind-proof sand-blocking device and wind-proof sand-blocking system

Abstract

The invention discloses a wind-proof sand-blocking device and a wind-proof sand-blocking system, and relate to the field of wind sand prevention and control. The wind-proof sand-blocking device and the wind-proof sand-blocking system are used for optimizing the performance of the wind-proof sand-blocking device. The wind-proof sand-blocking device comprises a plurality of installation bases arranged at intervals, sand blocking parts and net assemblies. The sand blocking parts are constructed in a structure without holes, and are installed on the installation bases; the net assemblies are located above the sand blocking parts, and are fixedly connected with the installation bases or the sand blocking parts; the net assemblies include through holes; at least one sand blocking part and one net assembly are arranged between every two adjacent installation bases; and the height of the net assemblies is 0.3-0.8 of the height of the sand blocking parts below the net assemblies. According to the technical scheme, while sand blocking, wind blocking and dust suppression are effective, disturbance to wind and sand flow can be reduced to the maximum extent, local airflow stability can be guaranteed to the maximum extent, and influence on a project area is reduced.

Description

technical field [0001] The invention relates to the field of wind and sand prevention, in particular to a wind and sand prevention device and a wind and sand prevention system. Background technique [0002] As a renewable and clean energy source, solar power has developed rapidly all over the world in recent years. Desert areas have the advantages of abundant solar energy resources and cheap land, making large-scale desert thermal and photovoltaic power plants one of the main types of development in this industry. [0003] The inventor found that due to the natural environment in desert areas, the following problems generally exist in large-scale desert thermal and photovoltaic power plants: [0004] (1) Sand damage is serious. Sand damage is the greatest harm to desert thermal and photovoltaic power stations. Sand damage is a great threat to the protective fence around the project area. The wind and sand are persistent and cumulative, which can easily cause the protective ...

AI Technical Summary

Problems solved by technology

[0004] (1) Sand damage is serious. Sand damage is the greatest harm to desert thermal and photovoltaic power stations. Sand damage is a great threat to the protective fence around the project area. The wind and sand are persistent and cumulative, which can easily cause the protective fence to be buried and eroded etc. Once the sand enters the project area over the protective fence, it will cause destructive hazards to the infrastructure, equipment, and ground surface in the power station;

[0005] (2) Harm from strong winds. Strong winds occur frequently in desert areas. Strong winds can cause fatal damage to photothermal mirrors and photovoltaic modules, seriously affecting the safe operation of power stations;

[0006] (3) Dust hazard. Dust falls naturally in the power station area to form dust, which seriously restricts the conversion efficiency and lifespan of photothermal photovoltaic power generation. Dust reduces power generation by 7% to 35%. The "hot spot effect" is formed by uneven light reception, which seriously damages the life of photovoltaic modules
