IN-PIPE INSPECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To eliminate the need for feeding facilities including a battery and a cable and restrict the larger size of a device by providing a turbine rotating part with a moving vane rotated by an in-pipe air flow caused by an in-pipe differential pressure to drive a generator with the rotation of its shaft for generation. SOLUTION: An in-pipe inspection device 1 guided into a pipe 20 is moved in the pipe 20 by towing a tow member 14 hooked on a hook member 15 for a static vane supporting member 11 to an arrow direction. When the in-pipe inspection device 1 is moved, a differential pressure is developed between the front side and the rear side in the moving direction of the in-pipe inspection device 1 as a boundary to cause an in-pipe air flow in opposition to the moving direction. The air flow allows a moving vane 8 located at the front stage of a turbine rotating part 2 to be rotated. A shaft 4 formed integrally with a rotation support 5 is rotated with the rotation of the moving vane 8 and the rotor of a generator 3 is also rotated for generation. Generated power is supplied to inspection equipment including a camera and a damage finder used for in-pipe inspection to be operated.
