Claims
- 1. A device for surveying subterranean hollow spaces, comprising a surveying system arranged on the end of a cable having reinforcing jacketing, said surveying system comprising:
- an oblong, largely tubular housing, said housing having a closed top face and a closed bottom face and being divided into at least three sections comprising a top section, a center section and a bottom section having a free end;
- a pivot joint connecting the top section and the center section, said pivot joint permitting relative rotation of the center section around a longitudinal axis of the surveying system;
- a tilting joint connecting the center section to the bottom section, said tilting joint permitting changing of the inclination of the bottom section relative to the center section around an orthogonal axis of swivel relative to the longitudinal axis of the surveying system;
- a rotary drive adapted to rotate the center section;
- a tilting drive for tilting the bottom section;
- an instrument located in the center section for determining the absolute rotary position of the center section;
- a rotary controller for controlling the rotary motion of the center section;
- an exchangeable sensor carrier forming a part of the bottom section at its free end;
- at least one measuring sensor disposed in the sensor carrier, said sensor using ultrasound as an echo sounder for measuring the hollow space;
- an angle sensor located in the bottom section for determining the absolute angle of inclination of the bottom section relative to the perpendicular,
- wherein the surveying system is lowerable into the hollow space through a drilled hole via the cable, said cable being adapted to connect the surveying system to an energy supply, measuring instruments and recording instruments, and wherein the housing protects the surveying system against the physical conditions prevailing in the drilled hole and hollow space to be surveyed.
- 2. A device according to claim 1, wherein the bottom section comprises a base segment and an exchangeable sensor carrier, wherein the angle sensor is arranged in the base segment, and wherein the exchangeable sensor carrier is connected with the base segment by a coupling having form-locking elements, said coupling preventing torsion and tilting and allowing for mechanical and electrical coupling of said sensor carrier with said base segment.
- 3. The device according to claim 1, further comprising a controlling device for controlling the tilting drive, said controlling device being connected to the angle sensor and allowing for data transmission from the angle sensor.
- 4. The device according to claim 1, further comprising a device for stabilizing a desired movement of the surveying system and suppressing an undesired movement of the surveying system, said device having elements selected from the group consisting of a rotating gyro and moveable countermasses.
