Device for solving problem of local differential settlement of pipeline through three rotating compensation devices

The invention discloses a device for solving the problem of local differential settlement of a pipeline through three rotating compensation devices. The device comprises a first pipeline body (4) and a second pipeline body (5). The first pipeline body is connected with a first short pipe (12) which is connected with a second short pipe (13). The second short pipe is connected with the second pipeline body. The first rotating compensation device (1) is mounted between the first pipeline body and the first short pipe, the second rotating compensation device (2) is mounted between the first short pipe and the second short pipe, and the third rotating compensation device (3) is mounted between the second short pipe and the second pipeline body. The axes of the first rotating compensation device, the second rotating compensation device and the third rotating compensation device are parallel, and the axes of the first pipeline body and the second pipeline body are parallel. The device adopts the three rotating comp
