Device for testing ducts
First Claim
1. A device (1) for examining an interior of ducts and registering data and features of the ducts, comprising:
- sensing instruments, includingat least one camera (3, 5),at least one distance measurement apparatus,at least one apparatus for measuring properties of the medium contained in the duct, said at least one apparatus being at least one selected from the group consisting of a conductivity sensor (17) and a turbidity sensor (19),a location transmitter (10) that emits data relating to the current position of the device (1), the location transmitter (10) being an electronic transmitter configured to communicate with a duct locator, andan acoustic pick-up sensor (18) that registers leaks in the duct by drip loss or leakages;
a control unit for controlling device in communication with the sensing instruments, the control unit having a storage medium for storing data received from the sensing instruments and configured to transfer data to an external data device;
an illumination apparatus (4) assigned to the at least one camera (3, 5); and
an energy storage device (11) configured to provide electrical power for supplying the device with energy,wherein the device (1) is configured to float freely in the flow of media in a duct being examined, an adjustable air bladder (6) being located in the device (1) configured to adjust a property of flotation of the device (1).

Abstract
A device (1) for registering data and features of ducts includes at least one camera (3, 5), at least one distance measurement apparatus and at least one apparatus for measuring properties of the medium contained in the duct. Furthermore, provision can be made for an illumination apparatus (4), a tracking sensor (10), which emits data in relation to the current position of the device (1), and an inclination measurement device (inclinometer and gyroscopic compass 9). The device can have a passive or active drive for moving the device (1) along the duct. The device (1) can register a length recording of the duct with the aid of photo geometry or with sound, radar, acceleration sensors and/or mechanical distance measurements. Thus, after a duct has been inspected, each point can be assigned precisely in terms of length.
