A turbine-driven in-tube generator

Abstract

The invention relates to a turbine-driven in-pipe power generator used for in-pipe construction such as pipeline coating, pipeline shaping and pipeline descaling, and providing power for in-pipe construction equipment. The technical scheme of the invention is as follows: a front barrel body and a rear barrel body are installed at the two sides of a middle barrel body; leather cups are arranged at the outer sides of the front barrel body and the rear barrel body, and are fixed by baffles; an end cover is installed on the end part of the rear barrel body; the power generator is installed on the end cover through a rear support; a valve seat is installed on the end part of the front barrel body; a speed reduction motor is installed on the valve seat through a front support; a valve element is installed on the end part of an output shaft of the speed reduction motor; a main battery is arranged in the middle barrel body and connected to the power generator; an auxiliary battery is arranged in the front barrel body and connected to the speed reduction motor; a turbine is arranged between the front barrel body and the rear barrel body; and the shaft of the turbine is connected with the power generator. The turbine-driven in-pipe power generator disclosed by the invention is used for long-distance pipeline construction operation; and an in-pipe medium pressure is used as a power source, and the power is convenient to acquire.

Description

technical field [0001] The invention relates to an in-pipe generator driven by a turbine, which is used for in-pipe construction such as pipeline coating, pipeline shaping, and pipeline descaling, and provides power for in-pipe construction equipment. Background technique [0002] In the transportation of fluid media, compared with tank transportation, pipeline transportation has the advantages of large transportation volume, continuous transportation, and low operating costs, and is widely used in the transportation of fluids such as oil, water, and gas. Usually, pipelines are laid underground. Under special conditions such as landslides, debris flows, and heavy-load extrusion, the pipelines will be squeezed and deformed, and even large deformations of instability will occur. Someone proposed an in-pipe repair scheme for deformed pipelines, which is more efficient and economical than the pipe cutting replacement scheme, and has advantages. This solution uses the robot in t...

Problems solved by technology

At present, this type of in-pipe robot is driven by a battery, and the power of the battery is limited, and the construction work in the tube is heavy and the power consumption is high, so a series of battery packs have to be used for power supply.

Such a long string of in-pipe tools has poor passability, and is prone to damage and jamming in the curved section of the pipe.
