Definitions

  • Fig. 1 is a boat 1 on an anchor 2, with which it is connected via an anchor chain 3.
  • the latter can consist in the usual way of a chain leader extended by a hawser.
  • a waterproof housing 4 is attached to the armature 2, which contains a three-axis, piezoelectric acceleration sensor and a preamplifier circuit connected to its outputs. This is connected to the boat 1 via a three-core, insulated cable 5. The lines of the cable are used both for the supply of the preamplifier circuit from the boat and for the return of the Sensor output and then amplified measurement signals to the boat ..
  • the cable On the boat side, the cable is wound on a drum 6, which (not shown) is set up to always exert a certain moment in the direction indicated by an arrow, so that the cable despite the sea state and other own movements of the boat 1 always remain under moderate tension, among other things in order to avoid a possible jamming of the cable 5 and anchor chain 3.
  • the cable 5 is electrically connected to a receiving station (not shown in FIGS. 1 and 2) (FIG. 4).
  • the anchor 2 is sketched in the form of a Danforth anchor because the flat blade surfaces of this type are particularly suitable for fastening the housing 4 by simply screwing it on.
  • practically any type of anchor can be used.
  • the transmission cable 5 will not, as shown in FIG.
  • the three wires of the cable 5 run from the drum 6 to the receiving station on board the boat shown in the block diagram of FIG. 3, it being noted that this so-called receiving station is not only used for receiving and processing signals, but also among other things. also the supply of the preamplifier and the function test of the entire system.
  • Fig. 4 the housing attached to the armature is again indicated and designated 4.
  • the reference numerals 11a, 11b, 11c denote the piezoelectric acceleration sensors arranged orthogonally to one another and 12 the associated amplification circuit.
  • 5 the three-wire connection cable to the boat is indicated and the Em pfangsstation as a whole is designated 14.
  • a charging circuit 15 fed by the on-board electrical system (not shown) charges its own accumulator 16, which itself supplies the receiving station 14 in order to ensure the greatest possible security.
  • the essential parts of this circuit are: a voltage monitor 17 and an encoder monitor 18, a power amplifier 19 for the incoming signals, an adjustable compensator 20 to determine whether a certain threshold value has been reached, a reset logic 21 and one by the compensator 20 and the reset logic 21 controlled alarm circuit 23.
  • the practical use of the facility is roughly as follows. After anchoring, the system is switched on and checked for functionality and the presence of sufficient power reserves. The compensator is then adjusted until the signals received by the piezoelectric sensors when the armature is stuck are below the set threshold value by a certain amount.
  • the threshold value set in this way can depend on the prevailing sea conditions, the type of bottom, the anchor and the anchor tackle. As a rule, it will not be exceeded as long as the anchor holds. Breaks but if it is dragged and ground, then it also suffers such strong - albeit often short - accelerations on sandy or muddy ground that the signals emitted by the acceleration sensors 11a, 11b, 11c exceed the set threshold value in the receiving station and thus trigger an alarm. The necessary safety precautions can then be taken. In order to avoid false alarms caused by jerking of the anchor chain when the threshold value is set relatively low, it can be advantageous to insert a short rope between the chain and the anchor shackle.
  • the housing 4 ′ containing the piezoelectric acceleration sensors lies on a short line 5 ′, independently of the armature 2.
  • the drum 6 is then omitted and the line 5 '(or in some cases the connecting cable between the housing and the boat which fulfills its function) can be fixed on board. It is clear that in this way a swooping of the boat caused by wind or current is indicated, even if the anchor stops, by pulling the housing 4 'around on the bottom and suffering corresponding accelerations.
  • the length of the line that is allowed without triggering the alarm can be regulated by the length of the line 5 '.
