Definitions

  • the invention relates to an underwater tool (UWAG) according to the preamble of claim 1 and is based on z. B. by FR-A-2402576 and WO-A-79/01136 known underwater vehicles, in which a depth-dependent variable gas pressure cushion protects the devices against impermissible pressure differences.
  • Such underwater vehicles are to be equipped with pressure tanks, seals and stuffing boxes that have grown according to their depth of use and would therefore be used for tools that, for. B. must be carried by divers or should be able to be used as remote-controlled underwater handling devices, unwieldy heavy, complicated in construction and expensive.
  • the mechanical and space requirements for bilge pumps were also unsatisfactory.
  • the object of the invention is to create a light and uncomplicated UWAG which is also suitable for great depths (high depth pressures) and which requires less pressure protection effort and can be drained in a simple manner.
  • the energy balance of the operation of the UWAGS corresponds to that of a corresponding above-ground use.
  • a gas air, nitrogen or the like
  • An electrical cable is in fact much less lossy to operate as an energy connection and is also less expensive and much more flexible than a corresponding deep-water hose.
  • the quieter and vibration-free draining processes with the UWAG according to the invention that can be achieved with the gas pressure cushion also represent a considerable advantage and make work easier for the divers who may be accompanying the UWAG. Less mud obstructing visibility is whirled up and there are fewer pump-related flows in the area of the UWAGS.
  • a jet cleaning nozzle With a high-pressure water pump, a jet cleaning nozzle can be operated via a hose connection with a valve gun, the weight and volume reduction of the devices allowing an advantageous small construction and mobility.
  • the flood protection in the pressure vessel is considerably improved with minimal additional effort.
  • the internal pressure of the pressure vessel is automatically adapted to changes in the depth by coordinated external pressure reducing valves or bilge or surface valves.
  • So-called lying three-plunger pumps have proven (according to claim 8) for use as water high-pressure pumps with a directly attached gear and hydraulic motor to be particularly favorable for gas pressure compensation and the bilge device according to the invention, because the resulting leak water reliably results in an impermissible increase in the pump or Motor housing can be prevented.
  • the small size and mobility of the UWAGS make it easier to use when combined with so-called diving assist devices and its suitability as a «modular part for more complex underwater systems.
  • the entire UWAG can also be used directly on an underwater vehicle, e.g. B. docked like a backpack, operated.
  • the UWAG is shown using the example of a water jet cleaning system.
  • Sludge cleaners, soil removal nozzles or water jet pumps etc. can also be operated according to the same principle.
  • an energy source 1 preferably placed above water, e.g. B. a generator on board a ship
  • an energy supply and / or signal connection 2, 2A to the devices 4 located in a pressure vessel 3, which here consists essentially of a high pressure water pump 5. If this pump is not driven by an electric motor, the energy and / or signal connection line 2, 2A can also first be led to the underwater hydraulic center 6 of a possibly further diving support vehicle, which usually has its own on-board hydraulics anyway.
  • the drive energy for the devices 4 can be obtained from there via line 2A as pressure medium pressure, so that no separate cable from UWAG to energy source 1 is required.
  • the pressure vessel 3 or the devices 4 in the same that is to say usually a high-pressure water pump 5 and its motor 7, are protected from the high ambient water pressure in depth by a correspondingly increased internal pressure from the gas pressure cushion by means of a gas pressure cushion 8 connected to the pressure container 3 .
  • Pumps and motors etc. can thus be designed for normal housing pressures, as they also occur at atmospheric pressure, because now the differential pressure between the gas pressure in the tank 3 or in the pump 5 and the water pressure surrounding both now hardly any higher loads than when used Water results.
  • the pressure vessel 3 which is also the housing of the respective devices 4, z. B. the high pressure water pump 5 or the motor 7, once shown as a trackable by the diver satellite device of an underwater vehicle with a hydraulic center 6 and a second time as a backpack-like docked additional element.
  • the pressure vessel 3 which is also the housing of the respective devices 4, z. B. the high pressure water pump 5 or the motor 7, once shown as a trackable by the diver satellite device of an underwater vehicle with a hydraulic center 6 and a second time as a backpack-like docked additional element.
  • a long-term integration into the underwater vehicle is also conceivable.
  • the energy supply line 2A initially opens into a switching device 11 at the pressure vessel 3 of the devices 4. Both the switching device 11 and the pressure vessel 3 are connected to one another via gas pressure lines 12 with the sections 12A and 12B or 12C and 13 with the section 13A Gas storage container 14 connected.
  • a medium pressure stage 12A is formed in its outlet line 12 by means of two water pressure-dependent pressure reducing valves 16, 17 connected in series after a shut-off valve 15. From the same branches a second Gas horrlei device 13, 13A, the flow of which can be controlled by a solenoid-operated directional valve 18 via an underwater cable 19 from the switching device 11.
  • the latter in turn receives, via a signal line 20, switching signals with regard to any leakage water accumulations that may occur in the pressure vessel 3 by means of a sensor 21 used in the same.
  • this device detects any water that has accumulated in the pressure vessel 3 by means of a defined, limited increase in the vessel internal pressure compared to the ambient water pressure automatically pushed back outwards via a bilge valve 22 and, at the same time, self-regulating by means of an opposing flood valve 23 to ensure that a pressure equalization to the ambient water pressure quickly occurs at every depth.
  • the pressure vessel 3 and also the devices 4 or machines used therein are thus only exposed to minimal pressure differences (for example a maximum of 3 bar), and can therefore be light and be relatively inexpensive and work with good efficiencies.
  • the flood valve 23 opens when the system pressure falls below the external pressure of z. B. 3 bar the water flow to the pressure vessel 3 and thus protects it by reducing the existing pressure difference to a safe value.
  • the valve 23 is thus a safeguard for the pressure vessel 3 or the pressurizable devices 4 against malfunction or failure of the pressure compensation system.
  • the high-pressure water pump 5 takes the water from the environment via a filter 24 and an intake line 25 and presses it into a high-pressure hose 10, which, for. B. opens into a spray gun valve 9.
  • the pump 5 is driven by an underwater motor 7, which is designed either as an electric motor or as a hydraulic motor.
  • a hydraulic motor would preferably be driven by a z. B. located in a diving support vehicle hydraulic center 6 from.
  • the motor 7 is controlled via its corresponding supply line 26, which is fed either via the above-mentioned hydraulic center 6 or (in the case of pure electrical supply) via the direct supply from the energy source.
  • the switching on and off of the internal pressure increase via the solenoid valve 18 in the medium pressure line 13 and the adjustment of the medium pressure can of course also be carried out manually by the accompanying diver if necessary, in order to adjust the pressure, e.g. B. with depth changes, can easily make.
  • the bilge pressure is set in a defined manner with a bilge pressure reducing valve 27 installed in the second gas pressure line 13 or 13A.
