[0001] The utility model relates to the technical field of water conservancy projects, in particular to a safety fence for water conservancy projects. Background Art

[0002] Water conservancy and hydropower projects are comprehensive engineering facilities that can convert water energy into electrical energy. They generally include reservoirs formed by water retaining and water discharge structures, water diversion systems of hydropower stations, power plants and electromechanical equipment. The high water level of the reservoir flows into the plant through the water diversion system to drive the hydro-turbine generator set to generate electricity, and then enter the power grid through step-up transformers, switch stations and transmission lines. There are many dangerous buildings in water conservancy and hydropower, so water conservancy project safety fences are naturally needed. Water conservancy project safety fences are used to prohibit unauthorized personnel from entering dangerous areas. However, some current water conservancy project safety fences cannot change the height of water conservancy project safety fences according to the actual terrain, which can easily lead to some water conservancy project safety fences being too low, making it dangerous for unauthorized personnel to enter.
