PROBLEM TO BE SOLVED: To provide a self-standing type turbine crawler traveling in a pipe in which there is a flow and obtaining a motive force from the flow, configured to convert the fluid energy of fluid such as water or air flowing in the pipe into mechanical energy or the like and capable of performing various operations and traveling in the pile by using the energy without needing any electric cable or any motive force hose.SOLUTION: A turbine crawler includes a main frame, a pipe inner surface contact seal, and a rotor with a rotary nozzle. By fluid injected from the rotary nozzle, the rotor is rotated at a high speed, and mechanical energy is taken out from a fluid pump connected to the rotary shaft of the rotor, or electric energy is taken out from a connected generator. As a utilization example, in-pipe grinding material blasting can be carried out, and a used grinding material can be transferred to the outside of the pipe without using any blast hose or suction hose.SELECTED DRAWING: Figure 1 |
