In the 1 to 6 is the water transportation means according to the invention, also called water scooter, generally with the reference numeral 1 Mistake. The water vehicle 1 has a housing 3 consisting essentially of three housing parts, namely a rear-side housing part 5 , a bow nose 7 and a center tube part 9 ,

The nose nose 7 is made of a polyoxymethylene. The middle tube part 9 consists of a fiber-reinforced plastic and has a much smaller wall thickness than the nose cone 7 , The rear housing 5 is made of aluminum.

Both the rear housing parts 5 as well as the bow nose 7 have at their the middle tube part 9 facing edge a paragraph structure 11 . 13 , In each case two grooves are incorporated on the assumption of O-rings, in closer contact with the center tube part 9 stand.

The rear-side housing part 5 carries outside a flow baffle 15 , which has a nozzle shape in the flow direction and by four support struts 17 on the outside of the rear-side housing part 5 is attached.

The flow baffle 15 surrounds and protects an operator in front of the drive screw 19 , which at the rear end of the rear housing part 5 is arranged.

The drive screw 19 is Momentkraftübertragungsgemäß on a shaft 21 including an end nut 23 attached with rounded outer surface. The wave 21 is a conventional rolling bearing on Innentragflansche the rear housing part 5 rotatably mounted and is connected to a coupling device 25 connected to the electric motor 27 is flanged. The coupling 25 and the electric motor 27 are via corresponding carrier on the inside of the rear-side housing part 5 attached.

The electric motor 27 is largely radial of the thin-walled middle tube part 9 surround. Adjacent to the electric motor 27 is arranged a rechargeable accumulator, which is selected from the family of nickel-metal hybrid accumulators or lithium-manganese accumulators, which in particular are not prone to exhaust and are resistant to high temperatures. These accumulators are particularly advantageous because they do not tend to explode in the event of mechanical damage or overcharging.

The accumulator 29 is made up of two parallel plates 31 . 33 stored, whose peripheral shape substantially the inner cross section of the central tube part 9 corresponds and for supporting the middle tube part 9 to serve inside.

The plates 31 . 33 have a paragraph structure on your perimeter section. The opposite heel structure is used for radially receiving the accumulator 29 , wherein the distance of the opposite paragraphs to the radial extent of the accumulator 29 is adapted. The plates 31 . 33 are longitudinally displaceable on two support rods 35 . 37 stored. The axial position of the accumulator along the support rod 35 . 37 is so far adjustable, as with the trim of the water scooter 1 can be adjusted in the water.

The carrying poles 35 . 37 are by a screw connection to a flange 39 the rear-side housing part 5 attached, what in 6 is apparent. Bow nose side are the carrying poles 35 . 37 over one across the entire cross section the bow nose 7 extending crossbar 41 connected with each other. The traverse 41 rests on the inside of the bow nose 7 from what's in 6 is apparent. The traverse 41 has a passage 43 which is essentially on the center axis M of the water scooter 1 lies.

On the outside of the bow nose 7 is a depression 45 introduced, in which an operating lever 47 a quick release 49 is retractable, so that no part of the operating lever from the recess 45 projects axially and radially.

The quick release 49 serves to the loosely fitted housing parts 5 . 7 . 9 to tense.

The quick release 49 has an eccentric part 51 that on the operating lever 47 is attached. The operating lever 47 including the eccentric part is pivotable on a shaft 53 attached, extending from the eccentric part 51 axially through a hole 55 in the bow nose 7 extends through. With folded operating lever 47 ( 8th ), ie in the tensioned state of the quick release 49 extends the longitudinal extent of the shaft 53 over the opening 43 out. The quick release 49 has a driver 61 at the end of the shaft facing the interior of the container 53 is attached.

The opening 43 is the traverse 41 has a substantially rectangular shape, to which the driver 61 is adapted to pass through the opening 43 in the traverse 41 by match.

Around the opening 55 in the bow nose 7 seal, are in the area of the hole 55 two O-rings arranged. Furthermore, between the eccentric part 51 and the nose nose 7 a rigid ring disk 63 arranged, which is formed from a pressure-resistant plastic, such as polyamide. The ring disk 63 concentrically surrounds the shaft 53 with game.

The annular disc has on her the operating lever 47 facing side a recess (not shown in detail), which is in particular positioned asymmetrically to the central axis M. The recess takes the eccentric part 51 flat on, so that a large friction surface between the annular disc 63 and the eccentric part 51 is trained. Due to the radial clearance between the annular disc 63 and the shaft 53 can the ring disk 63 when tensioning the quick release 49 the eccentric part 51 consequences. In this way is an independent opening of the quick release 49 avoided.

An operator can use the water scooter 1 just wear it by one at the nose 7 attached handle 65 is used, mainly via a screw connection to a reinforced nose section 67 is screwed.

Assembly of the housing parts with internal pressure compensation

To the housing parts, namely the rear-side housing part 5 , the middle tube part 9 as well as the bow nose 7 to assemble together, first becomes the center tube part 9 on the sales structure 13 the rear-side housing part 5 postponed. They are the ones in the sales structure 13 lying O-rings elastically deformed to form sealing surfaces. Then we the nose nose 7 on the middle tube part 9 set up by the paragraph structure 11 at the free end edge of the middle tube part 9 is put on. As you can easily imagine, when pushing the nose 7 due to the then engaged seals on the sales structures 11 . 13 a hermetically sealed housing 3 created, with the further pushing on the nose cone 7 the interior of the housing is compressed, which makes it difficult to assemble, disassemble and secure the housing parts together.

To balance the pressure when putting the housing parts together 5 . 7 . 9 ensuring is the quick release 49 equipped with a pressure compensation device. The pressure compensation device consists, in particular in 8th and 9 it can be seen from a housing-inside blind hole 69 , which on the one hand end face on the inside of the housing facing the end of the shaft 23 opens. The pressure compensation bore on the other hand has a radially extending, outwardly open access 71 into the blind hole 69 essentially in the middle of the shaft 53 opens, so that a fluid connection between the radial access 71 and the open end of the blind hole 69 is formed.

When mounting the bow nose 7 on the middle tube part 9 should the shaft 53 to activate the pressure equalization direction in a partially extended position as shown in FIG 9 is shown. The active pressure compensation position is achieved because of the radial access 71 outside the case 3 of the water scooter 1 lies. When putting on the bow nose 7 on the middle tube part 9 can the pressurized inside air through the blind hole 69 and the radial access 79 flow freely to the outside, when disassembled in the opposite direction of flow. When bracing, so when pressing the quick release 49 , the shank becomes 53 mostly inside the case 3 sandwiched what was in 8th is apparent. Continue as in 8th is indicated, is the radial access 71 in the tensioned state of the quick release 49 inside the case 3 , which prevents ingress of water through the pressure compensation device.

Key keyhole arrangement of the quick release

When clamping the housing parts 5 . 7 . 9 becomes the operating lever 47 starting from the in 9 shown pressure compensation position displaced axially inwards, so that the driver 61 complementary to the shape through the opening 43 the traverse 41 fits. When retracting the shaft 53 by pressing the undocked operating lever 47 of the quick release 49 is the operating lever 47 almost perpendicular to the longitudinal direction L of the recess 45 posed. In this position is the driver 61 complementary to the opening 43 the traverse 41 aligned.

Comes the eccentric part 51 in pressure stop with the annular disc 63 , is the driver 61 beyond the opening 43 and is like a key inserted through a keyhole.

To now a locking of the driver 61 with the crossbar 41 To realize, becomes the operating lever 47 pivoted by 90 ° and is thus aligned in the longitudinal direction L. Due to the pivoting of the operating lever 47 is also the driver 61 perpendicular to the openings 43 and can not go through the opening anymore 43 to be led back. By moving the operating lever 47 becomes the eccentric part 51 Active and builds corresponding clamping forces between the nose cone 7 and the traverse 41 on, rigid with the rear housing part 5 is connected and from the driver 61 is taken.

Redundant power supply

As in 10 is indicated schematically, the energy of the power supply 73 through the accumulator 29 provided by an electrical circuit 75 with the electric motor 27 electrically connected, which is a closed housing 77 having.

From the accumulator 29 extends a main line 79 , and a return line 81 flows from the electric motor into the accumulator 29 ,

Battery side is in the main line 79 a fuse 83 integrated, which is a so-called master switch 85 follows, which can be manually operated by an operator.

The master switch 85 is in 5 realized by a rotary knob switch, which has a turret arranged on the outside and a switching structure in the interior of the housing 3 having. For the special reliability of the master switch 85 the inside switching structure is encapsulated or encapsulated with plastic. The main master switch 85 has an excessive intervention on the energy supply 73 of the water scooter 1 ,

Following the main master switch 85 is a parallel circuit 87 with a main stream branch 89 and an emergency power branch 90 integrated.

In the main stream branch 89 is a main power switch 91 for manual opening and closing of the main flow branch 89 integrated.

As in 6 is apparent, is the main operating switch 91 formed by a Reedschalterkonstruktion, by a in the support strut 17 integrated reed switch 93 and by a in a pivot lever 95 rimmed magnets 97 realized. The swivel lever 95 is on a steering handle 96 of the water scooter 1 stored.

When swinging the pivot lever 95 in the in 6 shown position, the magnet happens 97 contactless the reed switch 93 so that it is activated and the main operating switch 91 is closed. In this way is an electrical connection between accumulator 29 and the electric motor 27 about the main hospital 89 realized.

So that an operator the speed of the water scooter 1 is in the main flow branch 89 following the main operating switch 91 a potentiometer 99 integrated, the in 5 is formed by a rotary switch. The rotary switch has an external rotary knob for manual operation of the potentiometer 99 , The electronic potentiometer components lie within the housing 3 of the water scooter 1 and are encapsulated watertight or plastic-encased.

Also the potentiometer 99 closes an analog control and / or regulating unit 101 on, for example, based on driving parameters, a startup of the water scooter regulated. Also other control options for controlling the water scooter 1 can through the control and / or regulating unit 101 be realized. The control and / or regulating unit 101 acts on the engine 103 of the electric motor 27 one. About the return line 81 is the accumulator 29 with the engine 103 connected.

Should one of the components of the main current branch fail, such as the failure of the potentiometer 99 , the control and / or regulating unit 101 or the main power switch 91 , the operator can a functional operation of the water scooter 1 make sure by powering the electric motors 27 over the emergency power branch 90 is realized. For this, the operator must have an emergency operation switch 105 close in 6 is realized by a special reed switch arrangement. The emergency operation switch 105 has a slider 107 who has a magnet 109 contains and along a support strut 17 is displaceable. Inside the support strut 17 is a reed switch 111 arranged, which is then activated when the slide 107 with the magnet 109 is pushed over him. In 6 is the emergency stop button 105 shown in the unclosed state.

Like also in 6 it can be seen, the individual strands of wire from the electronic components to the electric motor 27 to the accumulator 29 shown. These are related to the circuit diagram 10 Of course.

Following the emergency operation switch 105 is a digital control and / or regulating unit 113 integrated on the engine 103 of the electric motor 27 can act.

It should be noted that for the protection of the control and / or regulating unit 101 . 113 of the main flow branch 89 or emergency branch 90 inside the case 77 of the electric motor 27 can be accommodated, as in 10 is indicated.

Of Further, it should be noted that an alternative electrical Power supply (not shown) can be realized thereby, that two separate batteries are used, thereby providing redundancy with regard to the energy generating unit is realized. In this case, the main master switch between a Connection with the first accumulator, the connection for the second accumulator or a neutral position are switched, in an electrical connection neither to the first nor to the second Accumulator is realized.

The in the foregoing description, figures and claims disclosed features can be used both individually and in any combination for the realization of the invention be important in the various embodiments.
