Definitions

  • the present invention provides a method of propulsion of a vessel as defined in claim 1 and a passenger motor-driven vessel for performing such method,a s define din claim 3.
  • Preferred features of the invention are set out in the dependent claims.
  • the lower water drive unit and the underwater wing are always submerged under the water surface during the start-up and ride, while the bottom part of the float, into which water enters and also floods the upper water drive unit, and the mast are at least partially submerged under the water surface before the start or after the finish, but during the start-up, the float and the part of the mast rise above the water surface and the upper water drive unit thus loses its water supply and no longer contributes to the driving of the vessel such that it can run idly or, more preferably, in order to save energy, decrease the noise, and decrease the environmental burden, can be transiently deactivated.
  • the flight mode is achieved mainly during a fast ride.
  • the transitional ride mode is such a ride mode in which the upper water drive unit is at least partially flooded, i.e., in particular start-up, finish before a stop, sharp turning, slow ride, etc.
  • the upper water drive unit is best placed in the axis of the float in its rear bottom part.
  • An essential feature of the invention is that in the transitional ride mode, both water drive units are operated simultaneously, each having its own electric motor. Both the lower water drive unit which is common in the devices of the state of the art and in addition, according to this invention, also an added upper water drive unit, which greatly simplifies the start-up and stop of the vessel or its control during sharp turning, are operated.
  • the upper water drive unit decreases or eliminates the heeling moment of the float and at the same time of the rider, provides smoother start-up of the vessel and smoother speed changes during other transitional ride modes, facilitates control of the vessel, provides the rider with greater stability and allows for a safer ride and a comfortable ending of the ride with minimized falls of the rider or multiple persons present on the float and thus becomes attractive to a wider range of users, even the less skilled ones.
  • the device of this invention responds in a simple way to a step change in the size of the drag of the wetted areas during the ride, even without a complex system for evaluating the vessel's deflection from its rest/balanced position, height, coordinates, etc., and without compiled electronics for tilting the float relative to the mast.
  • it is a balancing of the forces without further active intervention, i.e., by the upper water drive unit simply emerging above the water surface level by the buoyancy force, the forces are balanced by the upper water driver unit not being flooded with water, i.e., in its essence it passively ceases to counteract the decreased drag of the water of the float that occurs when rising above the water surface.
  • a part of the control and communication system is a control unit, which may stand alone or be embedded in one of the motor regulators, and a wired or wireless connection to the components that the control unit controls and/or collects data therefrom or sends data thereto.
  • the control unit may be placed in the float, in the mast, or in the main body of the underwater wing, preferably it is placed in the float as a part of the upper regulator but may also be placed in the lower part of the vessel as a part of the lower regulator.
  • the placement in the float is preferable because the float can then be used independently after disconnecting the mast for a ride on the water only, not for a flight above the water surface.
  • the vessel further comprises at least one sensor of wetting functionally connected to the control and communication system that deactivates the electric motor of the upper water drive unit when all such sensors of wetting emerge above the water surface, and conversely, when at least one such sensor of wetting is flooded with water, the control and communication system activates the upper water drive unit.
  • the sensor of wetting connected to said control and communication system is advantageous because it enables reliable and automated deactivation and activation of the electric motor of the upper water drive unit at the appropriate time, thereby decreasing noise and saving energy and environment. Such an appropriate time occurs mainly during a fast and straight ride, i.e., in the flight mode of the float.
  • Said sensors of wetting are placed on the vessel such that they are not wetted by water in the flight mode, but at least one of the sensors of wetting is wetted in the transitional ride mode.
  • the sensor of wetting is placed on the vessel at such a place that the water surface reaches at the moment when the sharpest change in the size of the surface of the wetted areas occurs as the float rises above the water surface, or at a place where the motor of the upper water drive unit ceases to be flooded with water as a result of the motor rising or water entering the upper water drive unit above the water surface.
  • the sensors of wetting are placed on the bottom part of the float or at a level that is 0 to 20 cm below the float, for example, they are attached to the upper part of the mast.
  • a single sensor of wetting is sufficient to achieve the effect, but for improved maneuvering multiple sensors of wetting may be placed, in particular at the same height level, for example on opposite sides of the mast, which is preferable, for example, for turning, such that when at least one of these sensors is wetted, the upper water drive unit is activated, and when all the sensors of wetting are pulled out of the water, the upper water drive unit is deactivated.
  • Means for the implementation of the switching on/off of the electric motors, which are connected to the control and communication system, are a common part of vessels with an electric motor.
  • these can be switches.
  • the control unit then receives signals not only from the controller but also from the sensor(s) of wetting. According to these or other signals, it sends the signals to the regulators, which then control the motors in terms of speed, power, voltage, etc.
  • the bottom part of the float for the placement of the sensor of wetting means the part of the float that is submerged in the water when the vessel is at rest in its normal position, for example before the start-up, when the float is not yet loaded by a person - the rider.
  • each electric motor is functionally connected to a separate regulator to increase or decrease the speed of the electric motor.
  • Both the lower regulator functionally connected to the lower electric motor and the upper regulator functionally connected to the upper electric motor are controlled by the control and communication system.
  • the control and communication system is implemented such that each regulator with electric motor is functionally and communicatively connected to the control unit, most preferably the control unit is implemented as a part of the upper regulator, wherein both regulators are connected to the control unit by two-way functional communication, either wired or wireless.
  • the upper regulator is then preferably placed near the upper electric motor and the lower regulator near the lower electric motor.
  • the control and communication system regulates by means of a special implemented algorithm the mutual power ratio of the upper electric motor and the lower electric motor by means of at least one of said regulators in order to achieve a stable ride, i.e., such that after subtracting the counteracting drag forces, the partial thrust force acting on the float with the rider is as large as the partial thrust force acting on the underwater wing.
  • a stable ride i.e., such that after subtracting the counteracting drag forces, the partial thrust force acting on the float with the rider is as large as the partial thrust force acting on the underwater wing.
  • the upper part of the vessel does not overtake the bottom part, or vice versa, i.e., so that both resulting acting forces generated by the lower and upper water drive units are approximately the same and the heeling moment is minimal, i.e., close to zero.
  • Maintaining the correct ratio of speed and power by regulating them on one or both electric motors increases the effect of achieving smooth changes in the movement speed of the vessel in the transitional ride modes
  • the activation and deactivation of the upper water drive unit and/or speed regulation is controlled by the control and communication system connected to, among other things, the user's control device, furthermore, to the sensor of wetting by water, to the means for activating/deactivating the lower and upper electric motors, and the lower and upper regulators.
  • the instruction of the control and communication system to activate/deactivate the electric motor of the upper water drive unit based on the wetting status of the sensor of wetting takes priority over the speed regulation of the electric motors.
  • the user enters instructions via the control device to increase/decrease the speed or stop, i.e., enters requests for power changes.
  • the control unit it is pre-set and pre-programmed how the power ratio of the individual electric motors should be set at the given speeds.
  • the control unit can be reprogrammed.
  • the heeling moment in the transitional ride mode is decreased by approximately 50 % during the start-up under the same conditions and other vessel parameters.
  • a program may be implemented in a data carrier connected integrated in the control and communication system, for example in a memory of the control unit or an external memory disk, furthermore, this data carrier or control unit with an integrated data carrier carrying said program, where the program is adapted to perform the above methods of propulsion of said vessel controlled by the control and communication system, which can also process instructions entered by the user via the control device.
  • Another object of the invention is a passenger motor-driven vessel for performing the above mentioned methods of propulsion thereof, where this vessel comprises a mast, a float attached to the upper end of the mast, an underwater wing integrated in the lower part of the mast or connected to the mast, a lower water drive unit integrated in the lower part of the mast or attached to the lower part of the mast with a lower electric motor functionally connected via the lower regulator to the control and communication system, to which a control device and a means for activating and deactivating the lower water drive unit are functionally and communicatively connected, where the essence of the invention lies in the fact that the vessel further comprises an upper water drive unit with an upper electric motor placed in the float, which is, via the upper regulator, functionally and communicatively connected to the control and communication system, which is functionally connected to the means for activating and deactivating the upper water drive unit.
  • the mast serves as a fixed connection of the lower water drive unit to the float and optionally also connection of the supporting areas of the underwater wing. Sufficient stiffness is a priority, especially at the place of connection of the mast to the float.
  • the mast is suitably hydrodynamically shaped such as to cause the least possible drag and at the same time to allow the cabling for the lower water drive unit to pass through its inner part.
  • the underwater wing can be as commonly known from the state of the art, it contains supporting areas connected by a truss or the main body of the underwater wing or a similar body, most often in the shape of an aircraft, i.e., the front supporting areas are larger than the rear ones, and it is placed in the lower part of the mast, preferably attached to the lower part of the mast or connected to the lower end of the mast, where the mast extends from the truss or main body of the underwater wing vertically perpendicularly and the axis of the truss is parallel to the direction of the ride of the vessel, or the underwater wing may be an integral part of the lower part of the mast with the supporting areas extending.
  • the engagement means of the upper and lower water drive units is most preferably the propeller, blades of which allow the forward movement of the float with the rider during the forceful engagement into the water.
  • the lower water drive unit can ensure the forward movement of the vessel even if the float rises above the water surface.
  • the forward force of the vessel is affected by the amount of water in the upper and lower water drive units. While the lower water drive unit is still submerged, the upper water drive unit gradually emerges above the water surface during the start-up and has no water supply for the engagement, so the upper electric motor preferably switches off or runs idly for a certain period of time.
  • control and communication system comprises a mutually communicatively connected control unit with an upper and a lower regulator
  • the underwater wing comprises supporting areas connected by the main body of the underwater wing, where the lower water drive unit with the lower electric motor and the lower regulator are placed in this main body, where the control unit is placed as a part of the upper regulator, and furthermore, the upper regulator and the communication module are placed in the float.
  • the control and communication system is adapted for controlling the above methods, is connected to the user's control device, to the means allowing activation/deactivation of the upper and lower water drive units or the upper and lower electric motors, is further connected to the lower and upper regulator, or, according to the invention, also to the sensor of wetting, if it is a part of the vessel, so as to be able to receive and process data from these parts of the device, evaluate whether and in what order to perform sub-actions according to predetermined priorities, and control the drive of the vessel.
  • the control and communication system contains a program for controlling both drive units on the basis of inputs from the measuring devices, for example from the thrust wetting, when all such sensors of wetting emerge, the control unit switches off the upper electric motor of the upper water drive unit in which the engagement means is already idle without the presence of water and no longer supplies any thrust for the forward movement of the float. This decreases noise and energy consumption. If at least one sensor of wetting is submerged below the water surface level, the upper electric motor is switched on again. If both drive units are in engagement, i.e., both have water supply, the control and communication system connected to the lower and upper regulator of the speed of the electric motor modifies their mutual ratio according to the pre-entered rules by changing the speed on one or both electric motors of the drive units.
  • Both regulators have a software-limited maximum power and maximum speed, which can be reached if the rider adds a 100% power requirement on the manual control, i.e., presses the pedal or button with a similar function to accelerate the vessel to the maximum. Values for partially added power are then derived from these maximum values by the set dependency in the control and communication system.
  • the control and communication system controls both the speed regulation and the activation and deactivation of the upper water drive unit during transitions between ride modes, and preferably of both drive units during the start and completion of the ride or unexpected interruption of the ride, for example due to a fall, etc.
  • the longitudinal axis of the electric motors of the water drive units is most preferably parallel to the longitudinal axis of the float, i.e., in the normal standard position of the vessel at rest before the start when it is not, for example, overturned due to an accident, the electric motors are thus positioned substantially horizontally.
  • the mast and underwater wing can be removable from the float.
  • the mast and the underwater wing attached to it or integrated in it, or alternatively the wing connected by other connecting means, can be easily dismounted from the float and reattached, which allows both for space-saving transport and for the use of the float with an upper water drive unit for the classic ride of the motor-driven float on the water surface without the wing and the mast, thus, the rider can use both variants, a ride on the motor-driven float without the underwater wing, which is, along with the mast, dismounted, and flight on the float using the underwater wing attached to the mast.
  • the float can be a motor-driven surfboard, for example, its base is composed of a laminate chassis sealed against the ingress of water into the inner spaces which house the upper water drive unit and other components necessary for the operation of the water surfboard.
  • the float is suitably hydrodynamically shaped such as to allow comfortable ride in a straight direction while also being effective when turning.
  • On the upper area of the float lies, kneels, or stands the rider who controls the water surfboard.
  • the surfboard turns by transferring the rider's weight and the forward force is regulated by the rider using a manual controller, for example with remote or wired transmission.
  • the solution of the invention substantially decreases or eliminates the problem of starting and ending the ride of the motor-driven vessels with underwater wing known from the state of the art operating only with the lower water drive unit, since activation of the upper water drive unit in combination with the operated lower water drive unit does not cause a step change in the drag force but rather a more gradual change in the drag force occurs more smoothly.
  • the upper water drive unit thus compensates for the heeling moment during the start-up and the step drag force, thus eliminating most rider falls, especially in the case of beginners, and significantly increasing the safety of the ride. These are mainly side falls, during which there is a risk of contact of the rider the sharp edges of the supporting areas.
  • the engagement means most often the propeller of the lower water drive unit, is completely covered to avoid contact with the rotating blades of the propeller.
  • Vessels driven by an electric motor may include other important or implicitly include standard components for the overall operation of the vessel, but these do not contribute to the solution of the given problem and their enumeration is not necessary to protect the invention, and a person skilled in the art knows that they are automatically included in such a vessel.
  • an implicitly included part of vessels driven by an electric motor is an accumulator as an energy source for the electric motor and for powering communication device and electronics.
  • the accumulator is placed in the float by quick-release mechanisms such that it can be quickly and conveniently taken out and connected to a charger without having to disassemble other parts of the float.
  • the accumulator is during the ride cooled by the surrounding water, which flows around the battery by means of special inlet channels by means of a suitably shaped float.
  • the start-up and completion of the ride are so-called transitional modes, in which the upper water drive unit is used.
  • both water drive units are engaged in the operating mode and both drive units provide the optimal amount of thrust for a stable ride.
  • the upper water drive unit eliminates the large heeling moment caused by the lower water drive unit.
  • the start-up is comfortable and the same as on a standard water motor board in a kneeling position with the rear foot in the binding. For beginners, it is also possible to start lying down and put feet in the bindings after the float has a certain speed.
  • the buoyancy force from the supporting areas increases so much that the float lifts off the water surface and the vessel enters the flight mode on the supporting areas.
  • its emergence above the water surface is according to the invention, detected by the sensor of wetting and the control and communication system switches off the upper water drive unit.
  • the vessel is thus driven only by the lower water drive unit, which remains submerged below the water surface and the float is in the flight mode above the water surface.
  • the sensor of wetting gets wet, when the upper water drive unit is activated and the upper water drive unit is partially or completely flooded with water, the vessel enters the landing and water intake mode, i.e., the transitional ride mode.
  • the float can be a jet ski or a small boat for multiple people.
  • the invention is not of such importance for them.
  • the lower electric motor 14 is functionally and communicatively connected to the control unit 13 via a lower regulator 12 and the upper electric motor 15 is functionally and communicatively connected to the control unit 13 via an upper regulator 16 .
  • the upper and lower electric motors 14 , 15 are oriented with their axis substantially parallel to the axis of the float 1 .
  • the longitudinal axis of the lower and upper electric motors 14 , 15 is parallel to the longitudinal axis 8 of the float, i.e. in the normal standard position of the vessel at rest before the start when it is not, for example, overturned due to an accident, the electric motors are therefore positioned substantially horizontally 14 , 15 .
  • the mast 2 connected removably, i.e., here for example by means of screw connections that allow it to be removed from the float 1 or attached to the float 1 if required or in the case of transport.
  • the main body 10 of the underwater wing 3 in which the lower water drive unit 4 is placed is directly non-removably integrated into the mast 2 , or only the housing carrying the lower water drive unit 4 is integrated into the mast 2 , and the underwater wing 3 is connected to the bottom area of the float 2 via separate telescopic bracket.
  • the water surfboard differs from the previous example in that it additionally comprises a sensor 6 of wetting, placed at the interface of the mast 2 and the float 1 , see figs. 2 and 3 , and functionally connected to the control unit 13 deactivating or decreasing the speed of the upper electric motor 15 when the sensor 6 of wetting emerges above the water surface 7 , and conversely activating the upper electric motor 15 when the sensor 6 of wetting is flooded with water.
  • two or more sensors 6 of wetting may be placed for example 5 cm or 20 cm below the lowest point of the float 1 on the mast 2 or on the bottom side of the float 1 , wherein the activation of the upper water drive unit 5 occurs when at least one of them is wetted by water and the deactivation occurs when all the sensors 6 of wetting present emerge above the water surface 7 .
  • the ride on this device was much more enjoyable due to the lower noise in the ride modes when the upper electric motor 15 was switched off compared to the ride when the upper electric motor 15 was running for the entire duration of the ride.
  • the driving distance was increased due to battery saving when the upper electric motor 15 was switched off and the overall energy consumption was lower.
  • the control and communication system comprises the control unit 13 placed as a part of the upper regulator 16 , and the lower regulator 12 connected to this control unit 13 , wherein this control and communication system is further adapted to regulate the mutual power ratio of the upper electric motor 15 and the lower electric motor 14 by setting the speed of each of these electric motors 14 , 15 .
  • the rider enters the requests for changing the speed of the vessel during the ride, wherein the control and communication system further evaluates and controls the increase or decrease of power independently on each of the electric motors 14 , 15 according to a predetermined algorithm so as to achieve the optimal power ratio of the electric motors 14 , 15 to minimize the heeling moment and stable ride of the vessel.
  • the advantage of this solution lies in the fact that if the upper electric motor 15 emerges above the water surface 7 , the upper electric motor 15 does not increase the speed to the maximum but maintains the same speed, i.e., it rotates "idly" and has only minimal energy consumption. When the upper electric motor 15 is submerged under the water surface 7 , the upper electric motor 15 tries to maintain the same speed and thus immediately generates the required thrust.
  • the lower regulator 12 functionally connected to the lower electric motor 14 is placed in the body of the lower electric motor 14 . Alternatively, it may be placed near the lower electric motor 14 in the housing of the lower water drive unit 4 or anywhere in/on the lower part of the mast 2 , which is in the flight mode permanently submerged below the water surface 7 .

  • control and communication system is functionally connected, either by a wire or wirelessly, to the user's control device 17 , to the upper and lower water drive units 4 , 5 , or to the switches of the respective electric motors 14 , 15 as means for activating/deactivating them, to the lower regulator 12 , and the upper regulator 16 .
  • control and communication system is functionally connected to:
  • the control and communication system then controls the activation and deactivation of the upper water drive unit 5 , the regulation of power of the electric motors 14 , 15 , and possibly also the mutual power ratio of the electric motors 14 , 15 , using a program implemented in a data carrier connected to or integrated into the control and communication system, in which algorithms for prioritization or order of tasks are predefined.
  • the control and communication system receives signals from the sensor 6 of wetting and also from the wirelessly connected remote control device 17 controlled by the rider. The signal from the remote control device 17 is evaluated and power is dosed accordingly to the lower and upper electric motor 15 .
  • this sensor 6 sends a higher-priority signal to the control and communication system, and the control unit 13 slows down or switches off the upper electric motor 15 .
  • the lower electric motor 14 can be set by the control unit 13 at this stage of the control to deliver the same power 30 regardless of the switching off or on of the upper electric motor 15 .
  • the third exemplary embodiment uses all the advantages of the invention and thus produced the best results, as the rider had a significantly easier start-up and entry onto the vessel, had significantly less difficulty in maintaining stability during the ride and turning by transferring the balance. In their hand, they had only the remote control device 17 for increasing or decreasing the speed, starting, or stopping the vessel.
  • the optimal power ratio of the lower and upper regulators 12 , 16 was during the initial testing achieved during different operations by experimentally setting this ratio to different values and then, according to the results, the ratio was set to the optimal value at which the best results of improved stability in the transitional ride mode were recorded. These tests were also preceded by estimation with simplified simulated calculations.
