Water conservancy project pipeline with filtering function

The pipeline with the filtering function for the water conservancy project comprises a pipeline body, a fixing shell is fixedly connected into the pipeline body, a frame is installed on the inner sideof the fixing shell, a filtering net is fixedly connected into the frame, and connecting bases are fixedly connected to the top and the bottom of the frame. The frame is pushed into the fixing shell,the frame drives the connecting seat to move, when the positioning rod makes contact with the guide groove, the positioning rod moves upwards, the positioning rod moves to drive the transverse plateto move, the transverse plate moves to enable the clamping spring to deform, and when the positioning rod moves into the clamping hole, the clamping spring is clamped. And the positioning rod is clamped into the clamping hole under the condition that the clamping spring recovers deformation, so that the advantage of a filtering function is achieved, and the problems that an existing pipeline for the water conservancy projec
