Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a connecting pipe device for water conservancy and hydropower projects. Background Art

[0002] Water pipes are water supply pipelines. Modern decoration water pipes are all constructed by buried wall. There are three types of water pipes. The first type is metal pipes, such as hot-dip cast iron pipes, copper pipes, and stainless steel pipes lined with plastic. The second type is plastic-clad metal pipes, such as steel-plastic composite pipes and aluminum-plastic composite pipes. The third type is plastic pipes, such as PB.

It is only necessary to put the water pipes into the V-shaped block above the sliding body at the upper end of the base, and then rotate the fixing frame to wrap the water pipes. Since a spring plate is provided on the inner side of the fixing frame, the fixing frame will not cause excessive pressure to cause deformation of the water pipes when clamping the water pipes, so that the spring plate can play a buffering role, making the structure of the device reasonable and stable, and increasing practicality;
