New solar beacon light service in the Three Gorges
On January 8, 2009, in the Yunyang section of the Chongqing Reservoir Area of ​​the Three Gorges, the waterway management personnel were installing new solar beacon lights. This kind of navigation light integrates solar panels, batteries and lamps into one, with longer line of sight, higher sensitivity and better durability, which can effectively solve the impact of widening the river surface and large fog on the navigation of the ship in the Three Gorges reservoir area. At present, the waterway management departments of the Three Gorges reservoir area are being replaced one after another. Only 30 new solar beacon lights in Yunyang County have been put into use during the Spring Festival.
