AI Technical Summary

Technical Problem

Photovoltaic power plants in shifting sand areas face the threat of high-intensity sandstorms. Existing protective measures are ineffective in preventing sand from entering the plant area and also affect the passage of maintenance vehicles. Traditional sand-fixing measures are easily buried by sand and become ineffective. There is a lack of effective protective measures suitable for the interior of photovoltaic power plants.

Method used

A system of sand-blocking and sand-fixing barriers is formed by using infilled fencing and sand-fixing barriers around the photovoltaic power plant, combined with vehicle-mounted sand-blocking and sand-fixing barriers at the inner edge, utilizing plant bodies and elastic structures to block wind and sand while allowing maintenance vehicles to pass.

Benefits of technology

It effectively blocks wind and sand from entering the photovoltaic power plant, reduces pile erosion and sand accumulation, ensures unobstructed operation and maintenance channels, improves the protection range and sand prevention effect, and avoids the failure of traditional measures.

Abstract

The application provides a flow sand area photovoltaic power plant wind-sand prevention system and application thereof. The system comprises a filling type surrounding net sand prevention barrier and a filling type surrounding net sand fixation barrier arranged at the periphery of the photovoltaic power plant, and a through vehicle type sand prevention barrier and a through vehicle type sand fixation barrier arranged in an inter-board corridor at the inner edge of the photovoltaic power plant. The filling type surrounding net sand prevention barrier and the filling type surrounding net sand fixation barrier are used to prevent and fix sand, and most of the sand sources in the windward direction are intercepted and fixed outside the field area. The through vehicle type sand prevention barrier and the through vehicle type sand fixation barrier are used to prevent and fix sand in the inner edge zone of the photovoltaic panel array area, so that a small amount of flowing sand passing through the peripheral protection measures is fixed. The system protection concept is adopted, and the system protection of the body+periphery is formed. The peripheral sand sources are cut off, the wind-sand problem of the whole photovoltaic field area in the flowing sand area is effectively solved, and the convenience of maintenance is considered. No additional operation and maintenance channel needs to be reserved.
