Definitions

  • the invention relates to a motor watercraft with a vehicle body on which the user rests or sets up with a running in the vehicle body flow channel with a motorized water screw, the electric motor and the batteries and the control unit for the electric motor are housed in the vehicle body.
  • a motor watercraft of this type is by the WO 96/30087 known.
  • the user is on the vehicle body and the water screw in the flow channel is driven by a battery powered electric motor so that a water flow is sucked through the flow channel, which runs counter to the direction of travel of the motor watercraft.
  • the water flow can be kept away from the user and with the shape of the vehicle body and the fairway flow can be passed to the user over. This facilitates swimming and diving with the motor watercraft.
  • This embodiment of the motor watercraft is complicated in construction and from the viewpoint of maintenance not user-friendly.
  • the object is according to the invention heard that water screw, electric motor and control unit is designed as an underwater drive unit and housed in the flow channel, and that the batteries for the electric motor are placed in a separate housing, which is interchangeable installed in the vehicle body.
  • the summary of water screw, electric motor and control unit for the electric motor to an underwater unit and their placement in the flow channel brings a significant simplification in the structure of the parts, especially the vehicle body and for the maintenance of the motor water vehicle.
  • the batteries housed in a separate housing are easily removable for charging and can be replaced by a new housing with charged batteries.
  • the vehicle body has a lying surface or a platform for the user above the flow channel, then it can be used in two types of use.
  • the structural design can be further simplified in that the flow channel is integrally formed in the vehicle body.
  • an embodiment has proven, which is characterized in that the flow channel emanates with an inflow opening in the region of the bow of the vehicle body and ends with an outflow opening in the rear of the vehicle body and that the underwater drive unit as a suction device in the Flow channel is installed.
  • the housing is inserted with the batteries in a recess formed in the underside of the vehicle body recess, which is arranged outside the flow channel with the inflow opening in the region of the bow of the vehicle body.
  • the underwater drive unit is associated with a remote control device which removably attached to the vehicle body and a wireless transmission link to the control unit of the underwater Unit can be brought into active connection.
  • the vehicle body below the underwater drive unit in the flow channel has an openable plate, flap or the like. There is access to the underwater unit.
  • the outer contour of the vehicle body 10 substantially corresponds to the outer contour of the vehicle body of the WO 96/30087 known motor watercraft.
  • the flow channel 8 extends from the inflow opening 11 in the region of the bow to the flow outlet 12 in the rear region of the vehicle body 10.
  • an underwater drive Unit consisting of stator 1, electric motor 3, water screw 2 and engine control unit 4 installed.
  • the stator 1 is fixedly connected to the vehicle sump 10.
  • it also has the task of straightening the rotating water flow generated in the flow channel 8.
  • Such underwater drive units are today interpretable so that their use in the flowing water can be made without hesitation.
  • the vehicle body 10 can therefore be made freely outside the flow channel 8 and be as simple as possible, but streamlined and user-friendly designed as well as possible.
  • the flow channel 8 may be integrally formed in the vehicle body 10.
  • the flow channel 8 is formed by an upper shell 10.1 and a lower shell 10.2. These components are interconnected by means of suitable fasteners.
  • the flow channel 8 is made accessible by removing the lower shell 10.2. But below the underwater drive unit can also be a plate, flap or the like. Be provided, on the access to the underwater drive unit consists.
  • a recess 13 is formed in the underside, in which a housing 9 with the batteries 5 and 6 is detachably inserted.
  • the housing 9 with the rechargeable batteries 5 and 6 is easily and quickly exchangeable and can be replaced by a housing 9 with charged batteries 5 and 6, so that the motor watercraft is always operational.
  • the region of the inflow opening 11 of the flow channel 8 is superimposed by means of the housing 9 in such a way that free access to the rotor 2 is prevented, but water with a sufficient volumetric flow can be conveyed. With this simple measure it is achieved that the rotor 2 is accessible only when the housing 9 is removed, that is, when the electric motor 3 is de-energized.
  • a wireless remote control device is provided in the event that the motor watercraft is not operated in the horizontal operating mode but in such a way, that the user stands on the vehicle body 10.
  • the manual control unit 14 which preferably communicates wirelessly with the engine control unit 4, is held in the field of view of the user on the vehicle body 10. If the user is standing on the vehicle body 10, then the hand control unit 14 can be released from the vehicle body 10 and used. In this different operating conditions, such as the current speed, the depth or the state of charge of the batteries 5, 6 are displayed.
