Definitions

  • the invention is based on a motor watercraft the genus of the main claim.
  • Motor water vehicles belong to the group of motor-driven Watercraft, in which the one controlling the watercraft Person using this on or under the water surface is pulled.
  • the watercraft serves as Movement aid for the swimmer and diver and is also known as wet diving boat because the swimmer or Divers in no extra cabin or on the vehicle sits, but is in direct contact with the water.
  • a known generic motor watercraft (WO / A 92/00124) is in a curved flow channel a propeller driven by an electric motor arranged, the vehicle being arranged at the rear Handles are controlled by the person to be pulled. This person is largely exposed to the current, which is tiring.
  • the batteries are built into the fuselage, so that to charge the entire vehicle to the charging station must be brought and therefore, as long as loading, for the operation fails.
  • FR 1 584 195 In another known underwater vehicle (FR 1 584 195) the diver also lies face down on the device. Around here at least a little before the fairway flow can be protected by a transparent protective bell on the device be attached, which the head of the diver in front of the Current protects. Drive units are detachable on the Platform underside arranged.
  • the motor watercraft according to the invention with the has characteristic features of the main claim on the other hand the advantage that the propeller sucked water flow through the in the fuselage arranged flow channel the propeller largely is supplied laminar. Through the flow channel Water flow generated by the propeller then like this directed that on the one hand it does not hit the person's body and on the other hand is led slightly downwards, whereby the Depth control of the watercraft is simplified.
  • Another advantage of the invention is that the motor and the Control units above the flow channel in the fuselage are arranged, which results in a favorable weight distribution results, so that the at least partially on the Motor watercraft person lying the watercraft can be easily controlled since the drive flow is eccentric to the Center of gravity and thus the weight of the Person is easier to use for control.
  • Another advantage of the invention is that by the bow of the fuselage arranged flow structure in Combination with the flow channel arranged in the fuselage the fairway flow at the one controlling the watercraft Person is largely escorted by on diving trips.
  • Electric motor outside the flow channel in the fuselage arranged.
  • Such an arrangement has the advantage that in Flow channel no unnecessary turbulence and resistance in the water flow, which adversely affects the Efficiency of the drive impact through those arranged there Drive units arise.
  • the battery is in a separate removable and am Fuselage attachable container arranged.
  • Such Arrangement has the advantage that the batteries if necessary are quick and easy to replace.
  • the battery containing, in the direction of travel of the Watercraft detachable, container on the bottom of the hull arranged.
  • the electrical connection of the battery to the Control unit takes place via a plug connection between Bottom of the fuselage and top of the tank.
  • handles and body are ergonomically designed to fit in Connection with the person, especially through their Shifting weight, controlling the motor watercraft in a simple and convenient way.
  • a swimming bladder the volume of which is in the Can be enlarged or expanded for descent and emergence if necessary is scalable. This aid is useful to the diver particularly advantageous because the diver at least partly on the motor watercraft and not just is dragged behind this.
  • a rope bag is arranged in the housing, so that if necessary there is always a rope.
  • a bypass channel can be provided which the propeller to avoid big Loss of flow flow past such objects to let.
  • the device controlling the speed is released when the Handle (2) by the person immediately to zero speed posed. This is mainly achieved when the diver the motor watercraft automatically loses its The trip stops.
  • the shaft of the propeller in a bearing block arranged, which via radial struts on the wall of the Flow channel is attached. That way they are Storage of the propeller and electric motor entirely attached separately from each other on the housing.
  • the shaft penetrates the wall of the flow channel in the Area of curvature of the flow channel.
  • a transmission available preferably a belt drive or is a gear transmission and that is inside the housing is arranged.
  • display devices for on the outer surface of the fuselage Battery charge, depth, etc. in the diver's field of vision arranged to clear the diver over to inform certain data.
  • an inventive motor watercraft is in the Side view shown, the diver or the Float on top of hull 1 at least partially rests and holds on handles 2, which on both sides of the Fuselage are arranged.
  • Measuring devices 3 arranged, such as a Battery charger, a depth gauge or the like.
  • Measuring devices 3 arranged, such as a Battery charger, a depth gauge or the like.
  • the rest of the hull is as hydrodynamic as possible, in particular it shows the fairway flow redirecting to the person controlling the watercraft redirecting flow structure 4.
  • Flow channel 5 is arranged, with one in the front Area of the fuselage 1 existing inlet opening 6 and one on the stern side of the fuselage Outlet opening 7. This flow channel 5 is to the rest Interior 8 of the fuselage 1 sealed.
  • an electric motor 11th and a transmission 12 arranged one in the Flow channel leading shaft 13 actuated there in one Bearing 14 is arranged and a propeller 15 is actuated.
  • the batteries 9 are located on the underside 16 of the fuselage arranged container 17.
  • the container 17 is in Flow direction on the fuselage using a Fastening device 18 attached. Via the plug connection 19 becomes the control unit electronics with the battery power connected.
  • the diver can be pulled by the motor watercraft, by holding onto the handles 2 and from there the Speed of the propeller 15 controls, being for the drive Water through the inlet opening 6 into the flow channel 5 is sucked and conveyed out through the outlet opening 7, the motor watercraft being driven in the water.
  • Inlet 6 and outlet opening 7 are in this case by means of Slats or grilles secured so that direct access to the impeller screw is not possible.
  • the Motor watercraft primarily serve the handles 2, over which the diver determines a relative change in the position of his body to the Motor watercraft achieved, which is steerable. It is however also conceivable with the motor watercraft Control fins to be provided, either by hand or are electrically controllable.
  • Fig. 2 the drive part of the motor watercraft is related shown enlarged on Fig. 1.
  • a sheet 22 which is a frame 23 carries, on the one hand the electric motor 11 and on the other hand, the transmission 12 is arranged.
  • the Transmission has two pulleys 24 different Diameter to the high speed of the motor 11 on the required low speed of the propeller 15 to step down.
  • a belt 25 is used for speed transmission.
  • the shaft 13 is in its passage passed through the channel wall 21 in a tube 27, the its outer jacket is well sealed towards the channel wall 21 and leads to a bearing block 28 of the bearing 14 which radial struts 29 is attached to the channel wall 21.
  • Bearing blocks 28 are ball bearings 31 for the shaft 13 provided, as well as needle bearing 32 for a rotary the shaft 13 connected shaft bolt 33 on which the Propeller 15 is attached.
  • the liaison office between the tube 27 and the bearing block 28 is sealing executed.
  • the two can via a lubrication line 35 Bearings 31 and 32 are supplied with lubricant.
  • Ball bearings 36 mounted, which are arranged in the frame 23. The Smooth running is also important for the storage of the top Transmission shaft 32 ball bearings provided.
