Abstract
An inspection device for inspecting explosive environments. The inspection device may include a camera and an intrinsic safety barrier. The intrinsic safety barrier may be configured to receive camera power and control signals and transmit intrinsically safe camera power and control signals to the camera.
Claims20
An inspection apparatus for inspecting a rocket bore comprising:
- a camera configured to be used in a rocket bore, wherein the camera is configured to receive camera power and camera control signals from an area outside the rocket bore;
- an illuminating device adjacent the camera configured to receive illumination power and illumination control signals from the area outside the rocket bore;
- and
- an intrinsic barrier configured to receive the camera power, the camera control signals, the illumination power, and the illumination control signals in the area outside the rocket bore and pass the camera power, the camera control signals, the illumination power, and the illumination control signals to the camera and the illuminating device into the rocket bore in an intrinsically safe manner.

An inspection system for explosive environments comprising:
- an inspection head comprising a camera and an illumination device the inspection head configured to be secured within an explosive environment;
- an intrinsic barrier configured to receive electrical signals and power for the inspection head in an area outside the explosive environment and transmit intrinsically safe electrical signals and intrinsically safe power to the inspection head.
A method of performing inspections in hazardous environments comprising:
- mounting an inspection head inside a hazardous environment, the inspection head comprising an externally powered camera and an illumination device;
- transmitting power to the inspection head through an intrinsic barrier;
- transmitting electrical control signals to the inspection head through the intrinsic barrier;
- and
- receiving imaging data from the inspection head.
