Definitions

  • the invention relates to a drive arrangement for a sports or charter boat comprising a feed drive device with a propeller rotating about a rotation axis and with an electric motor for driving the propeller, wherein the feed drive device is held on a hull of the boat, and comprising an electric Energy providing power supply unit, which is electrically connected to the electric motor of the feed drive device for operating the electric motor.
  • a propulsion arrangement for boats having a plurality of propulsion devices is known.
  • the drive arrangement comprises, for example, four feed drive devices, which are arranged in the rear of the boat and serve as travel drives.
  • Each traction drive includes an electric motor and a coupled with the electric motor propeller, which acts as a thrust propeller.
  • the drive arrangement has two bow-side drive devices, which are designed according to the pump-jet principle and serve as a bow thruster.
  • the bow thruster improves the maneuverability of the boat.
  • the bow thruster in the event that the rear drives fail, alternatively take over the propulsion of the boat.
  • the bow thrusters are to be dimensioned so strong that the boat can be operated in the event of failure of the actual travel drives aft of the bow thrusters with reduced power or speed.
  • the drive arrangement is partially redundant and as a result comparatively complicated and expensive to implement.
  • the object of the present invention is to specify a drive arrangement, in particular for sports and charter boats, with which better maneuvering properties can be realized in a cost-effective and energy-saving manner.
  • the invention in conjunction with the preamble of claim 1, characterized in that the feed drive device is arranged as a drive in the bow region of the boat.
  • the particular advantage of the invention is that the boat can be easily steered due to the bow-side arrangement of at least one main drive and has good maneuverability. Since the propeller works in largely clean, that is untwisted water, the efficiency of the travel drives is also particularly favorable.
  • the drives are to be interpreted as the main propulsion of the boat so that aft the desired feed rate is available without further traction drives.
  • the aft-side arrangement of the main propulsion drive device in boats has been practiced for many years, because the propeller was driven by a rigid mechanical shaft in particular by a diesel engine and the rudder blade should be flown. Since the provision of electric motors as drives for the propeller can dispense with the mechanical shaft, there is the possibility of positioning the drive devices much more freely. Particularly good maneuvering properties result when the feed drive devices are arranged in the bow region of the boat. The boat does not have to be pushed over the stern. Rather, the stern is pulled from the bow. This is advantageous especially when maneuvering in the area of the port or on narrow waterways or inland waters.
  • the drive assembly is therefore particularly suitable for sports and charter boats and simplifies the steering of the boat especially for less experienced boaters. Drives are in particular scareless propeller with ring motors, Schottel drives or outboard motors in question.
  • the propeller can be realized for example in the manner of a double propeller.
  • the bow region comprises the front third of the boat length.
  • the propeller is designed as a draft propeller.
  • the propeller is seen in the direction of travel before the electric drive.
  • the efficiency of the drive improves, since the turbulence of the water in the design of the propeller in the manner of a draft propeller is particularly low.
  • At least two feed drive devices are provided on the bow side, wherein the feed drive devices are arranged symmetrically with respect to a longitudinal central axis of the boat on opposite sides thereof.
  • the symmetry results in a further improvement in the handling characteristics of the boat.
  • each individual feed drive device can be dimensioned smaller and therefore manufactured inexpensively. Furthermore, the redundancy improves the safety and reliability of the feed drive device.
  • the feed drive device is designed in the manner of a propeller pod drive (POD), wherein the electric motor and the electric motor connected to the electric motor via a shaft propeller provided below the water surface and are pivotable about a substantially vertical pivot axis.
  • POD propeller pod drive
  • a rudder is provided in addition to the at least one propeller pod drive or a normal rudder is present at the rear.
  • the propeller pod drive and the rudder can be spatially integrated or the rudder can be arranged downstream of the propeller.
  • the propellers can be arranged on one side of the nacelle or on opposite sides of the nacelle.
  • the feed-drive device from a basic position in which the propeller-carrying shaft is arranged substantially parallel to the longitudinal center axis of the boat, preferably +/- 90 ° pivotable.
  • a particular maneuverability results from the large pivoting range of the feed drive device.
  • the boat can therefore in particular in tight spots easy and comparatively precise.
  • the feed drive device can be rotated by a full 360 ° about the pivot axis.
  • the energy supply unit comprises an energy store for storing electrical energy.
  • an energy store for electrical energy the operation of the electric motors of the feed drive device is independent of the simultaneous power generation.
  • electrical energy can be generated from wind energy via suitable converters on board the boat and stored in the energy store.
  • the stored energy is then used at a later time to operate the electric motor.
  • Also can be dispensed with the power generation on board the boat.
  • the energy storage is then loaded, for example, at the berth with shore power.
  • the energy supply unit comprises a diesel-electric generator for obtaining electrical energy from fossil fuels.
  • electrical energy can be generated aboard the boat as needed by providing a diesel-electric generator.
  • the electrical energy generated by means of the diesel-electric generator can either be temporarily stored in the energy store or used directly for the operation of the electric motor.
  • the generator as well as the energy storage, in addition to the supply of the electric motor of the feed drive device also serve to supply other electrical consumers with electrical energy.
  • the energy supply unit comprises a photovoltaic module for the conversion of solar energy into electrical energy.
  • a drive arrangement which can be operated largely independently on the basis of renewable energy.
  • Fossil fuels or the like are expendable. Since these do not have to be carried on board the boat, there are also weight advantages.
  • a sports or charter boat which in the Figures 1 and 2 is represented by his boat hull 1, has an overall length 2 and a bow portion 3 extending in the front third of the total length 2.
  • the feed drive devices 5, 6 serve as the main drive drives for the boat.
  • Achtem ie arranged in the rear 16 of the boat traction drives can be omitted.
  • the feed drive devices 5, 6 are designed in the manner of propeller nacelle drives 5, 6. They each have a propeller nacelle 7, 8 and a propeller 9, 10.
  • the propeller 9, 10 is driven via a shaft 11, 12 by an electric motor 23, 24 arranged in the nacelle 7, 8.
  • the nacelle 7, 8 with the electric motor 23, 24, the propeller 9, 10 and the shaft 11, 12 are below a water surface thirteenth intended.
  • the propellers 9, 10 are in this case arranged in front of the respective associated gondola 7. 8 and consequently act as a draft propeller 9, 10.
  • the feed drive devices 5, 6 are each rotated about a vertical pivot axis 14, 15.
  • the propeller pod drives 5, 6 are then rotated horizontally from the illustrated basic position, in which the shaft 11, 12 extends substantially parallel to the longitudinal central axis 4 of the boat. Due to the pivoted arrangement of the propeller pod drives 5, 6, the boat changes its direction without the separate rudder being provided.
  • the propellers 9, 10 work here as Switzerlandpropeller.
  • the propeller pod drives 5, 6 are pivotable by at least +/- 60 °, preferably by +/- 90 ° or more from the basic position. It can be provided in particular that the propeller pod drives 5, 6 can be pivoted by 360 ° or +/- 180 ° or more.
  • the feed drive device comprises two propeller pod drives 5, 6 with propellers 9, 10, which are arranged behind the gondolas 7, 8 and act as thrust propellers 9, 10.
  • the feed drive device comprises two propeller pod drives 5, 6 with propellers 9, 10, which are arranged behind the gondolas 7, 8 and act as thrust propellers 9, 10.
  • the interaction of the drive devices 5, 6 with an energy supply unit 20 is in FIG. 4 shown.
  • the energy supply unit 20 has in the present embodiment of the invention, a diesel-electric generator 21 for generating electrical energy from fossil fuels and an energy storage 22 for storing electrical energy.
  • the electric motors 23, 24 are supplied with electrical energy by the diesel-electric generator 21 and / or the energy store 22 and then drive via the shaft 11, 12 to the traction propeller 9, 10.
  • the energy supply unit 20 can dispense with the energy storage 22 according to an alternative, not shown embodiment of the invention.
  • a photovoltaic module or a converter for generating electrical energy from wind energy can be provided instead of the diesel-electric generator 21, for example, a photovoltaic module or a converter for generating electrical energy from wind energy can be provided.
