Sewerage pipe inspection vehicle having a gas sensor
First Claim
1. A mobile vehicle apparatus for sewer pipe inspection, comprising:
- a power source;
a motor connected to said power source;
at least one endless member driven by said motor;
a camera connected to said power source;
a sensor operably connected for sensing sewer pipe ambient gas level; and
a controller responsive to said sensor and programmed to generate an alarm signal at a predetermined sensed ambient gas level approaching a danger level.

Abstract
An apparatus and method for inspecting sewerage pipes, including in combination with a first mobile pipe vehicle, a gas sensor vehicle for detecting pipe ambient gas. The combination includes an interface cable conveying power and operably connecting the combination to a control station positioned outside the pipe, a second vehicle having a support frame connected to the first mobile pipe vehicle, a gas sensor positioned on the second vehicle support frame and connected to the interface cable for sensing pipe ambient gas level, and a transceiver communicating with the gas sensor and connected to the interface cable for therethrough communicating with the control station. The second vehicle is preferably connected to the first mobile pipe vehicle by the interface cable and is thereby towed in the pipe.
