Control device and method for navigation-electricity junction tubular unit flow path body

The invention provides a control device for a navigation-electricity junction tubular unit flow path body. The control device comprises main shafts and sliding rods; the main shafts are connected withfirst telescopic rods; prisms are arranged on the first telescopic rods; a sliding rail and a sliding rail locking device are arranged at the bottoms of the main shafts; and the tops of the sliding rods are connected to the upper ends of the first telescopic rods through connecting rods, and the bottoms of the sliding rods are connected with probes. The control device for the flow path body is adopted, a flow path model is established through a BIM technology, the relation curve of the flow path variable cross-section radius and the coordinates is determined, the hook face space position of aflow path mould plate can be quickly positioned and inspected, the flow path construction progress is accelerated, and the flow path body quality is guaranteed. 本发明提供种航电枢纽贯流式机组流道形体控制装置，包括主轴和滑杆，所述主轴连接第伸缩杆，第伸缩杆上设有棱镜，主轴底部设有滑轨和滑轨
