Definitions

  • the invention relates to a scooter.
  • a scooter serves as a propulsion for a single person in the water and is used in particular by divers.
  • the drive of a scooter is usually done by an electric motor.
  • Diving scooters are known.
  • the scooter has a housing on which the diver hold on and can be pulled by the scooter through the water.
  • two handles are usually attached to the housing of the submersible scooter.
  • Known dive scooters have a single propeller, which is driven by an electric motor. The supply of the electric motor via an accumulator or a battery.
  • the maximum depth is usually determined by the pressure resistance of the housing. Weak point here are the seals at the point where the drive shaft for the propeller from the housing exit. These seals are regularly designed as a sliding ring or O-ring seals. When the pressure is increased, these can extremely increase the friction on the sealing surface. This must be compensated by an increased drive power, which can reduce the maximum depth. In addition, the seals are a wearing part that must be checked and replaced regularly to ensure the safety of the scooter.
  • the present invention seeks to provide an improved submersible, which has a high ease of use and can be operated safely.
  • the scooter according to the invention is given by the features of the main claim 1. Useful developments of the scooter are given by the features of the other claims.
  • the scooter according to the invention has a housing on which the diver can hold.
  • the scooter has at least two propellers, which can be driven in opposite directions. As a result, no counter-momentum can arise in the sum, which would have to be compensated by the diver. This means an increased ease of use and a reduced effort during use.
  • the two propellers could be driven by a common drive, which may be designed in particular as an electric motor.
  • each propeller can be equipped with a separate drive.
  • the drives can each have a separate control electronics.
  • each drive can also have a separate energy supply, in particular in the form of a rechargeable battery.
  • the use of two separate drive systems will cause failure one of the two systems still operation of the scooter is possible. Since the scooters are used in particular by professional divers in technical diving and, for example, cave divers, this can be lifesaving in an emergency. This effect can be further enhanced by the use of separate power supplies for the respective drives. In this case, if any part of the system fails, it will still be possible to operate the submersible scooter, which can ensure the diver returns to the water surface, thus ensuring its survival.
  • the drive shafts of the propeller can each be mounted in a sliding bearing.
  • no more seal is required, which can become brittle and thus pose a security risk.
  • by means of the slide bearing a greater depth of the scooter can be made possible.
  • the use of plain bearings is therefore of independent inventive importance and can be implemented in an immersion scooter with only a single propeller in an advantageous manner.
  • the housing can be releasably secured to the housing of the scooter with the sliding bearing. This attachment can be done for example by means of a screw. It is usually necessary to clean the scooter to clear the scooter of collected silt, grass and algae.
  • the housing of the sliding bearing may preferably be present at least one flushing bore, by means of which the interior of the electric motor can be flooded with water.
  • the magnets of the electric motor can be shielded in a watertight manner from the interior of the electric motor, so that they do not come into contact with the water.
  • This shield can in a structurally particularly simple embodiment by a cup-shaped housing, which seals the interior of the electric motor.
  • the rotor of the electric motor can be shielded by an inner housing waterproof. The ambient water during diving can be used in this case for cooling the electric motor, so that a highly effective and cost-effective engine cooling can be achieved.
  • the submersible scooter 10 according to the invention is in perspective in Fig. 1 shown.
  • the scooter 10 has a housing 12 to which one or more handles not shown here may be attached. At the handles, a diver can hold on to the scooter 10 through the water.
  • the housing 12 is regularly covered in the front area by a cap, which is not shown in the drawing. The shape of the cap can be adapted to the particular circumstances, even lighting the cap may be possible.
  • the scooter 10 according to the invention has two propellers 20, 22.
  • the propeller 20 rotates clockwise while the propeller 22 rotates counterclockwise. Due to this opposite rotation of the two propellers 20, 22, no counter-momentum arises, which would have to be compensated by the diver. In addition to the reduced effort for the diver results in a particularly quiet operation of the scooter, which also contributes to ease of use.
  • Each of the two propellers 20, 22 has its own electric motor 24, 26.
  • the electric motors 24, 26 each have their own energy supply in the form of an accumulator 30, 32 and their own control electronics 34, 36.
  • a drive shaft 44, 46 is driven, which ensures the rotation of the propeller 20, 22.
  • This drive shaft 44, 46 exits at the rear end of the scooter 10 from the housing 12 of the same.
  • the drive shaft 44, 46 is mounted after its exit from the housing 12 in a sliding bearing 50, 52.
  • the bearing in the sliding bearing 50, 52 ensures that no seals must be used, which represent wearing parts and would reduce the maximum possible depth.
  • the housing 54 of the sliding bearing 50, 52 has an approximately conical shape (see in particular Fig. 4 ).
  • a plurality of flushing holes 56 are distributed in the housing 54 in a distributed manner.
  • the flushing holes 56 extend through the housing 54, so that the interior 60, 62 of the electric motors 24, 26 is freely accessible and can be flooded with dive with water. Such water cooling is effective and inexpensive and is also hardly prone to failure.
  • the interior space 60, 62 of the electric motors 24, 26 is delimited by a pot-like housing 64, 66, which in the present example in each case consists of stainless steel.
  • This pot-like housing 64, 66 seals the motor interior 60, 62 waterproof and ensures that the magnets 70, 72 of the electric motors 24, 26 do not come into contact with the water. The magnets 70, 72 are thus protected against corrosion.
  • the rotor 40, 42 is also surrounded by an inner housing 74, which also consists of stainless steel in the present example. This inner housing 74 ensures that the rotor windings also do not come into contact with the water.
