Definitions

  • the invention relates to a carrier device for receiving measuring, monitoring, data storage and telemetry means and the like, which is connected by means of a tow rope and / or a connecting cable to a vehicle and towed by the latter in the state immersed in the water.
  • a large number of measuring and monitoring systems are required for exploring the sea, the sea floor, for observing and locating objects in the sea and on and in the sea floor, and these are arranged on carrier devices, which in turn are connected to the by a tow rope and / or a connecting cable towing vehicle are connected.
  • the vehicle which can be both a watercraft and a helicopter, can tow the carrier device at predetermined constant depths or the In another type of measured value acquisition, the carrier device is towed with periodically recurring changes in depth.
  • such a carrier device can be towed at predetermined courses at a certain distance from the sea floor or vertical profiles of the sea can be carried out continuously at fixed positions.
  • a watercraft is used for towing the carrier device, various interactions of different sizes occur, for example due to the rolling and pounding of the watercraft, flow resistance due to different orientation of the body of the carrier device to the main flow direction, rope twist, variable rope sag, variable cable pull, etc., so that the carrier device executes more or less uncontrolled horizontal and vertical movements around the target course.
  • the information content and the quality of the data recorded during such undesirable movements of the carrier device are naturally influenced (noisy), which is particularly the case for remote measurements from the carrier device (echo soundings, Doppler measurement methods, magnetic field measurements) for the time constant due to the constantly changing alignment of the corresponding sensors on the Carrier device plays a large and disadvantageous role.
  • the body of the carrier device is at least partially formed from a metal with a specific weight> 15 g / cm3.
  • the advantage of the device according to the invention is achieved by the optimized use of gravity, ie by using a body as an output weight with a specific weight> 15 g / cm3, the mechanical rigidity of the carrier device is made very large compared to the forces acting on the carrier device, for example through the flow resistance, cross flow influences, rope twist, cable pull and the like.
  • the carrier device according to the invention is that, in the case of a cable-guided, balanced output body, the required weight is not achieved by the length of the carrier device and the lowest possible specific weight, as in devices known in the prior art, but the body according to the invention is the cheapest hydrodynamic shape with the largest possible specific weight.
  • Tungsten (gamma approx. 19.3), tantalum (gama approx. 16.6) and depleted uranium 238 (gamma approx. 18.5) are preferably suitable as metals, the metal of the body of the carrier device also advantageously being composed of mixtures of different materials Metals, including those mentioned above, can exist.
  • the high specific weight of the metals used according to the invention means not only a high level of persistence with respect to horizontal and buoyancy forces, but also that the attack surfaces on the carrier device can be reduced on all sides during towing under water, since a very large mass is available in the smallest space.
  • a reduction in the water attack surfaces on the carrier device is also achieved in that, in contrast to the devices known in the prior art, this does not require control fins for horizontal and vertical deflection.
  • the metals with a specific weight> 15 g / cm3 are normally difficult to machine mechanically or not at all.
  • the metal is advantageously sintered to form the body, so that it can be used, for example, to create the final one desired shape can be machined like normal gray cast iron.
  • the body is advantageously provided with a swivel device, via which the body with the Tow rope and / or the connecting cable is connected.
  • the swivel device is advantageously provided with a slip ring device, so that data on the connecting cable, the can be integrated in the tow rope, can be transferred to the towing vehicle.
  • the body is essentially cuboid, since the forces exerted on the body by the water during the towing process are due to the large mass and extremely small volume of the body due to the high specific weight of the metal used are negligibly small.
  • the cuboid body also allows a relatively simple way of attaching the measuring, monitoring, data storage and telemetry means and also allows them to be exposed to the water to perform their tasks completely unhindered.
  • any number of bodies arranged side by side or one above the other can form the device, specifically each as required for measuring, monitoring, data storage and telemetry means and the like to be fastened thereon, and as a function of the desired degree of overall stability of the device when used in water.
  • the bodies can be assembled as identical units in the sense of an expandable system.
  • the body has an opening which essentially passes through it and into which the aforementioned means are inserted or can be inserted and fastened there.
  • the stability of the carrier device when towing in water can be increased, preferably by arranging on the body a guiding device which protrudes from it in the towing direction and which can preferably be essentially in the form of a baffle, for example made of stainless steel or the like.
  • the guide device has a plurality of through openings running transversely to it, which for example can be suitably distributed over the entire surface of the guide device.
  • the carrier device advantageously has a device for recording hydrographic standard parameters of the water (temperature, conductivity, speed of sound, pressure, speed x, y, z , inclination, direction, depth, acceleration, etc.), when the recording device is preferably highly miniaturized for minimization of the water resistance is formed, the carrier device allows the provision of two of these devices without difficulty, which applies equally to the telemetry means for transmitting the data from the detection device to the vehicle.
  • a watercraft 11 which tows the device 10 hanging on a tow rope or a connecting cable 12 in the water 13.
  • Fig. 1 is a hanging on a tow rope Apparatus visible that shows a typical known arrangement behind the towing vehicle 11 far behind the vehicle 11 itself.
  • the device 10 according to the invention also hangs almost vertically under the towing vehicle 11 during the towing process, which can be not only a watercraft, as shown, but also a helicopter.
  • the device 10 essentially consists of a body 14; 140, as shown in a side by side in FIG. 3.
  • a body 14 is constructed almost cuboid and has an almost circular opening, cf. Fig. 3 or a semicircular opening, see. Fig. 4 a, b, on.
  • the opening 14 is closed by a plate-shaped closure element 21.
  • the opening 16 crosses the body 14 completely.
  • a swivel device 15 is formed, on the upper part of which the tow rope 12 or the connecting cable 12 is fastened.
  • Measuring, monitoring, telemetry and data storage means 17, which can be seen by way of example from the illustration in FIG. 2, are fastened in a suitable manner to the body 14, 140 and connected to the detection device 20 by cables and the like.
  • a detection device 20 is arranged in each of the two openings 16 of the bodies 14, 140.
  • the detection device 20 which in principle is intended to record any data, depending on the predetermined task of using the carrier device 10.
  • the detection device has a modular, highly miniaturized hybrid technology. Via a highly miniaturized telemetry device also attached to the carrier device 10, data recorded by the detection device 20 by the measuring and monitoring means 17 can be connected bidirectionally to the corresponding systems on the towing vehicle.
  • the carrier body 14 consists of a metal with a specific weight> 15 g / cm3, the metal being used either elementarily or in the form of metal mixtures, for example a sintered tungsten-copper alloy, which has cutting properties like conventional metals (gray cast iron) and is very different can be easily machined.
  • the body 14 is preferably covered by a Teflon or titanium layer, which can equally apply to the other components 10 of the device. Due to the use of completely non-magnetic metals for the output body and the other parts of the device 10, the device 10 is particularly suitable for use for high-precision magnetic field measurements.
  • the device 10 can also have a guide device 19 which is arranged on the body 14, 140 in the towing direction 18, the guide device 19 generally only having to consist of a normal guide plate.
  • the guide plate 19 is advantageously with a plurality of not shown separately here Provide holes so that an impact on the position of the device 10 is reduced to a minimum. Experiments have shown that a guide device 19 designed in this way creates a very good position stabilization with respect to the horizontal deflection of the device 10.
