[0002] In the process of designing water intake from rivers, reservoirs and other water bodies, floating boat water intake is often used to reduce the impact on flood control, ecology and environment. The floating boat water intake form does not require complex underwater engineering, is simple to construct, has a short construction period, and has strong adaptability when the river hydrology and riverbed are prone to change. Therefore, it has been widely used in recent years. The floating boat is connected to the shore water intake pipeline through a connecting pipe, and flexible joints are set at both ends of the connecting pipe, one end is set on the boat and the other end is set on the shore.

[0003] In the previous design of flexible joints, the joints can only move in a horizontal plane or a vertical plane, the adjustment angle is very limited and 5 to 7 flexible joints are required, which can not meet the working conditions of large water level changes, and the installation is cumbersome and restrictive. The existing universal joints that can move in both horizontal and vertical directions increase the difficulty of construction and the difficulty of approval of relevant procedures due to their huge size and huge foundation. The commonly used flexible joints are either ineffective, complex, or inconvenient to operate and maintain. Utility Model Content

[0007] One transverse joint of the three-way pipe is connected to the transverse pipe through a sleeve-type rotating joint, and the other transverse joint is installed on the foundation or blocked through a sleeve-type rotating joint.

[0008] The horizontal pipe is connected to the water intake pipe via a flange, and the 90° elbow is connected to the connecting pipe via a flange.

[0009] A bearing for supporting the pipe is arranged inside the sleeve-type rotary joint, and a P-type water-stop rubber is arranged at the connection between the inner side of the sleeve-type rotary joint and the end of the pipe. A pressure strip is arranged on the P-type water-stop rubber and fixed to the inner pipe with bolts.
