The present invention discloses a device and a method for large-scale flow solidification treatment of dredged sediment in a pipeline without a yard. The device includes a dredger, a treatment unit and a use terminal that are communicated in sequence, where the dredger is connected with the treatment unit by adopting transportation units, a mud pump is arranged between the transportation units and the dredger to provide power, a plurality of transportation units are communicated in sequence by adopting relay pumps, the treatment unit includes a mixing system, a monitoring system and a data processing and control system, and the device is also provided with an air pump. The method for the flow solidification treatment of the sludge in the pipeline, provided in the present invention, fundamentally changes the mode where the traditional dredging engineering needs to set up a large number of sludge yards first, and then uses solidification treatment equipment for stirring and mixing treatment, which saves land, and does not have the problem of environmental pollution of yards, and therefore, the method has wide applicability; and a device and a method for mixing sludge and a solidifying material in a pipeline are provided, the injection speed of a solidifying agent is precisely controlled, the mixing effect is good, the emphasis is on the grading and judging standards of pipelines, and corresponding solutions are given.

An active folding wind turbine capable of resisting severe typhoons is provided. Each wind turbine blade includes an upper blade part and a lower blade part that are hinged to each other by a hinge device. A motor transmission system is installed in the lower blade part, is connected to the hinge device in a transmission manner, and can drive the upper blade part to rotate relative to the lower blade part through the hinge device, so that the wind turbine blade is bent. When the upper blade part rotates to an end of a travel, a blade tip of the upper blade part is propped against an upper end of the lower blade part of an adjacent wind turbine blade. A winch is built in an upper portion of the lower blade part of the wind turbine blade, and is provided with a cable.
