INSPECTING APPARATUS OF INSIDE OF PIPE

摘要

PROBLEM TO BE SOLVED: To provide an inspecting apparatus of the inside of a pipe of an inspecting apparatus in a system for inserting a sensor body into a pipe to be inspected while rotating the sensor body, and has improved wire passage capacity at the bending joint section of the inside of the pipe to be inspected by contriving the shape or the like of the sensor body. SOLUTION: The inspecting apparatus 1 of the inside of the pipe comprises the sensor body 11, and a tubular or rod-like support 12 that is connected to the base edge of the sensor body 11 for inserting the sensor body 11 into the pipe to be inspected. The sensor body 11 comprises a detection means for grasping the condition inside the pipe to be inspected and a covering member for covering the detection means. The covering member has a plurality of projections 11a, 11b at the tip side of the sensor body 11, and at the same time a cross section in an axial direction at a site other than the projections is nearly in an elliptic shape.
