Description

Technical Field

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

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water is a valuable resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet people's needs for water resources in life and production. During the construction of water conservancy projects, it is necessary to build safety fences to prevent outsiders from entering, so as to eliminate and reduce safety hazards. The following problems exist in the existing technology:

[0003] For example, a Chinese patent for a high-safety water conservancy project safety fence (publication number CN207211948U, application date 2017.08.25) discloses that it includes a support assembly, wherein a fixing assembly is arranged between each of the support assemblies, connecting columns are welded on both sides of the support assembly, a protective net is arranged on the fixing assembly, and connecting cylinders adapted to the connecting columns are arranged at both ends of the fixing assembly, a clamping ring is fixedly installed on the top and bottom of the protective net, a hook corresponding to the clamping ring is fixedly installed on the outer surface of the fixing assembly, the protective net is clamped with the fixing assembly through the clamping ring, and a bottom plate is fixedly installed at the bottom of the support assembly, the support assembly includes two support rods, and a connecting rod is arranged between the two support rods, a connecting block is welded on the inner wall of the support rod, and the head and tail of the two adjacent connecting rods are hinged to the connecting block through a rotating shaft, and the two adjacent connecting rods are hinged to each other through a roller, the fixing assembly includes two fixing rods, and a first spring is arranged between the two fixing rods, and the first spring is fixedly connected to the fixing rod through the fixing blocks arranged at both ends thereof. Similar structural designs cannot flexibly adjust the height according to usage conditions, which greatly reduces the practicality of the safety fence. Secondly, the fence cannot be reinforced and supported, making it prone to collapse. Utility Model Content
