Abstract

The invention relates to a device (1) for renovating a pipe, the latter being provided with at least one opening arranged in the wall of the pipe, said device (1) having a base unit (2) that can be introduced into the pipe, a clearing unit (3) that is movable relative to the base unit (2), and an electronic sensor arrangement for detecting the instantaneous position of the clearing unit (3) relative to the base unit (2). To make available a novel device (1) for renovating a pipe provided with at least one opening arranged in the wail of the pipe, which device permits reliable and inexpensive repair of the pipe, the invention proposes that at least one electronic inclination sensor is arranged on the base unit (2).

Claims

1. Device (1) for renovating a pipe, the latter being provided with at least one opening arranged in the wall of the pipe, said device (1) having a base unit (2) that can be introduced into the pipe, a clearing unit (3) that is movable relative to the base unit (2), and an electronic sensor arrangement for detecting the instantaneous position of the clearing unit (3) relative to the base unit (2) characterized by at least one electronic inclination sensor arranged on the base unit (2).

2. Device (1) as defined in claim 1, characterized by an electronic evaluation unit (13) configured for evaluating the data generated by the electronic sensor unit considering the data generated by the electronic inclination sensor.

3. Device (1) as defined in claim 2, characterized in that the electronic evaluation unit (13) is configured to control the movement of the clearing unit (3) relative to the base unit (2) considering the data generated by the electronic inclination sensor.

4. Device (1) as defined in claim 1, characterized by a unit for electronic recording of the instantaneous axial relative position between the pipe and the base unit (2).

5. Device (1) as defined in claim 2, characterized in that the electronic evaluation unit (13) can be arranged separated from the base unit (2) and the clearing unit (3) outside the pipe and is connected with an operating unit (14), the base unit (2) and a display unit (15).
