Abstract

The invention discloses a plastic pipe connecting device for water conservancy engineering, and relates to the field of water conservancy engineering. Aiming at solving the problem that connection isnot stable enough due to the fact that existing plastic pipelines for water conservancy engineering are prone to plastic deformation during connection, the invention provides the following scheme thatthe plastic pipe connecting device for water conservancy engineering comprises pipelines and a connecting mechanism, wherein the pipelines are connected to the two ends of the connecting mechanism; connectors are mounted at the ends, close to the connecting mechanism, of the pipelines correspondingly; the connecting mechanism comprises an outer ring, an inner ring and a connecting column; the connecting column is located in the inner ring; second connecting columns distributed in an annular array mode are connected between the connecting column and the inner ring; and the inner ring is located in the outer ring. The plastic pipe connecting device for water conservancy engineering provided by the invention is novel in structure, the connecting operation between the pipelines can be easilycompleted, the stability of connection between the pipelines and the connecting mechanism can be kept, the stability of pipeline connection is achieved, the occurrence of the phenomena of deformationand water leakage of the connecting pipelines is prevented, and the plastic pipe connecting device for water conservancy engineering is suitable for application and popularization.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a plastic pipe connection device for water conservancy engineering. Background technique [0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. Also known as water engineering. Water is an indispensable precious resource for 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 regulate and distribute water to meet the needs of people's life and production for water resources. Water conservancy projects need to build different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, canals, rafts, and fishways to achieve their goals. According to the purpose or service object, it ca...
