Description

The invention relates to a holder for single- or multi-channel probes for detecting objects and / or structures in the ground, under water and from the air, with a detector ( 3 ), in which the sensors and the electronics are arranged.

State of the art

Holders for probes, such as flux-gate magnetometers or Förster probes, have long been known. These brackets consist of an iron-free hand-held support frame, to which three to five probes are attached individually. Each of these probes is connected to the accompanying control and evaluation unit via a probe cable and battery cable (see Prospectus "Contaminated Sites and Geomagnetics", p. 10, Institut Dr. med. Förster GmbH & Co. KG, 02/2005 ; Prospectus "Systems for Combat Detection", p. Förster GmbH & Co. KG, 06/2006 ).

Furthermore, from the DE 20 2012 008 435 U1 a mobile carrier system for magnetic field detection probes comprising a frame, at least two holding means for each probe and at least three wheels connected to the frame.

Furthermore, from the DE 20 2012 007 159 U1 a trailer vehicle for detecting objects and / or structures in the ground by means of probes, sensors o. The like. Known, are received in the individual probes of a modular sensor carrier.

All these known solutions have the common drawback that the probes are individually attached to the support frame or chassis and each probe must be connected separately to the evaluation and control unit, resulting in a relatively high weight of the stretcher or chassis. In addition, magnetometer probes are heavy and cause considerable burden on the test personnel, especially in the manual guidance of multiple probes on the area to be detected, so that the track width for detection significantly limited and the time required is correspondingly high.

task

In this prior art, the present invention seeks to improve a holder for probes for detecting objects and / or structures in the ground, under water and in the air so that the exact alignment of the probes in the carrier increases, the weight of the Reduces probes and increases the track width of the probes by combining multiple probes into an array and reduces the burden on the test personnel with simplified and easier handling.
