Definitions

  • the present invention relates to an electric thruster intended for scuba diving.
  • Traditional underwater propulsion systems are designed like torpedoes and the main flow resulting from the rotation of the propeller is ejected along the axis of symmetry of the device. The diver must therefore move away from this axis and the master couple in the direction of movement is increased.
  • Figure 1 shows such a traditional propellant, the plunger must be offset along the axis OZ to stand above the turbulence generated by the propeller.
  • a technical solution consists in placing two turbo-engines on either side of the propellant according to document DE-A-35 23 758, but this solution is complex and expensive.
  • the present invention improves the performance of the propellant and facilitates the steering.
  • the propellant is constituted by a symmetrical symbolic hyperform by compared to the OXY movement plan, figure 2, of the diver. This form provides the equivalent of two swimming paddles profiled in the OX axis of movement.
  • Figure 2 shows the basic principle of such a system.
  • the diver holds the device at arm end in the axis of movement, the water is sucked through an opening 1 located at the front.
  • the incoming flow is then divided into two symmetrical transfers and driven back on either side of the diver.
  • the two secondary flows 2 are partially divergent to improve hydrodynamics and propulsion is by reaction.
  • wing profile chosen for the body is neutral, detail 5 in Figure 3, because when diving the weight is compensated by hydrostatic thrust and no dynamic lift should result when traveling.
  • Two headlights 8 and a speed control 7 can be integrated into the vehicle.
  • FIG 4 shows a diver equipped with such a system.
  • the waterproof accumulators 3 are placed outside the propellant, at the waist. They can also be attached to the back of the diver or to diving tanks. So structured the propellant is less bulky, lighter and more efficient.
  • the batteries placed outside replace the weights usually used to balance the diver.
  • a cable 4 provides electrical power to the motor integrated in the device.
  • the weight corresponding to the batteries can be compensated by volumes of foam of density less than one, this compensation can also be performed via an inflatable diving vest.
  • Polymer batteries with a density substantially equal to 2 can also be used and require little hydrostatic compensation.
  • FIG. 5 shows the balance of such a propulsion system produced according to the invention.
  • the body 9 made of materials of density less than one, produces a hydrostatic thrust directed upwards at G.
  • the total weight of the propellant including the body and accessories interiors such as the engine 14 and the control system 11 must correspond to G so that the thruster is in balance whatever its position.
  • the handles 10 integrated directly into the body and the reaction forces R must be substantially aligned in a zone Z as small as possible according to OX.
  • This exploded view of a propellant designed according to the invention also shows the body 9 made up of two symmetrical half-shells Manufacturing, assembly and maintenance are thus considerably simplified, investment in molds is reduced.
  • interior shapes are harmonized with the exterior shapes to reduce the maximum submerged volume.
  • the motor 14 in figure 6 is placed so as to correspond with the center of thrust hydrostatic G because it is the heaviest element and an offset would require balancing by additional masses.
  • a chamber 15 is arranged around the engine for its cooling, circulation water is provided by a calibrated conduit 21 whose inlet is located downstream of the turbine and green evacuation rear 16
  • This duct is calibrated according to the power chosen for the engine and the quantity corresponding heat to be removed.
  • FIG. 6 shows such a control element 11 comprising two arms provided with sealed switches 12 leading to the level of the grab handles.
  • This control element is obtained by overmolding the components on a card electronic and placed in a housing directly molded on the body.
  • the electronic circuit includes a switching power supply, a charge controller and a safety system in case of blockage of the turbine.
  • a simplified version includes only a control relay.
  • the axis of the motor comprises at its end a turbine 20 making it possible to suck up the water and repress in two transfers.
  • the initial flow generated by the high efficiency turbine is optimally divided.
  • the aspect flow dynamics is described in Figure 7.
  • the separation edge 28 operates a first division along the axis of geometric symmetry 27 of the transfer.
  • a zone primary impulse 25 resulting from an asymmetrical profile 26 of the conduit makes it possible to initiate a dynamic axis 22 towards the secondary pulse zone 24
  • the shape of the duct is obtained by the gradual passage from 26 to 23 along the axis of geometric symmetry and this results in flow along the dynamic axis with the minimum turbulence and better hydrodynamic reaction.
  • Control flaps 30 can be installed at the end of wings according to FIG. 8. They allow to act on the roll and the pitch by actuating two levers 32 located near the handles and linked to the flaps by two axes 29 perpendicular to the direction of movement.
  • the axis 29 drives an integrated nozzle 33
  • the corresponding housing consists of a recess rectangular with two separate contacts for power supply.
  • polymer batteries are arranged in the plane of joint according to a thickness of the order of 10 mm. They must conform to the interior profile of the thruster's body.
  • the body in two parts is produced by injection / reaction in material of density less than 1, and assembly is done by screws 19 placed perpendicular to the OXY plane, figure 6.
  • the body in two parts is produced by injection of material with a density greater than 1.
  • cells 18 are arranged according to the figure 6 and in which foam blocks are arranged in order to obtain a relative density less than 1 to compensate for the weight of internal organs.
  • each part of the body is hollow and formed by the assembly of two injected parts corresponding to the shapes, exterior and interior, of this.
  • the parts forming the body can be filled with synthetic foam to increase their mechanical resistance.
  • the body in two parts is extruded / blown in polyethylene.
  • Particularly light and resistant models are built in composite on a core synthetic foam.
  • Figure 9 shows an optimal way to perfectly balance the thruster using three additional 34 adjustable masses located at 120 ° on a circle centered on the hydrostatic thrust center.
  • this thruster is intended for both the diver and the deep equipped with compressed air cylinders only to the snorkeler.
  • This thruster can also be used for beach games, underwater ballets and as emergency equipment for firefighters for example.
