IN-PIPE TURBINE AND HYDRO-ELECTRIC POWER GENERATION SYSTEM

摘要

A system (1) to generate electricity from a fluid flowing through a pipeline. The system comprises a mounting arrangement to mount the system in a pipeline. The system comprises an elongate shaft (4), a turbine rotor (6), which is operable to rotate about the elongate axis of the shaft (4) when fluid in the pipeline acts on the turbine rotor (6). The system further comprises an electrical generator arrangement with a first part incorporating at least one magnet (12) and a second part incorporating at least one winding (14). One part of the generator arrangement is mounted to the turbine rotor (6) and the other part of the generator arrangement is mounted to a stator element (13) which is positioned adjacent the turbine rotor (6). The system further comprises a housing (3) which at least partly houses the turbine rotor (6), the shaft (4) and the electrical generator arrangement. The housing (3) comprises two parts (24, 25) that are releasably attached to one another such that the two parts (24, 25) of the housing (3) can be at least partly separated from one another to permit access to the turbine rotor (6) and the electrical generator system.

1. A system to generate electricity from a fluid flowing in a pipeline, the system comprising:
a mounting arrangement to mount the system in a portion of a pipeline; an elongate shaft; a turbine rotor which is mounted to the shaft, the turbine rotor being operable to rotate about the elongate axis of the shaft when fluid in the pipeline acts on the turbine rotor; an electrical generator arrangement comprising a first part incorporating at least one magnet and a second part comprising at least one winding, wherein one part of the generator system is mounted to the turbine rotor and the other part of the generator system is mounted to a stator element which is positioned adjacent the turbine rotor; and a housing which at least partly houses the turbine rotor, the shaft and the electrical generator arrangement, wherein the housing comprises two parts that are releasably attached to one another such that the two parts of the housing can be at least partly separated from one another to permit access to the turbine rotor and the electrical generator system.
