Description
SELF PROPELLED HYDRODYNAMIC TURBINE
The subject of the present invention is submergible radial turbine, which as propellant uses the hydrodynamic energy of moving water masses, and without additional pressure pump allows ejection of water on the surface. With its technical design on propelling side exploits the hydrodynamic energy of moving water masses. On its opposite side which turns against water flow, actively captures water and transport it to the centre of the pump through one direction Check Valve, which can be produced on any known technical way, with self locked flap or self lock ball in coned chamber. The most important technical requirement which device by invention must fulfill is its technical adaptation for long - term use under the water level. Submergible turbine must be fixed on concrete or similar basis, which is placed on the bottom of the water stream, which has beside water capture on its passive side, on the concrete basis built-in variety of energy consumer devices, which are driven by rotation of propelling of the turbine. The invention belongs to Class F01 D 7/00 of the international patent classification and it is by intention of use similar to submergible self propelled pumps, which I claimed in patents SI 9300175 A and P 200800218. Both previously claimed patents differs from new invention, because of completely differently shaped and designed propelling surfaces which do not allow hydrodynamic capture and direct pumping of water with propelling parts.
The technical problem successfully solved by the present invention is permanent self propelling of a pump submerged in water without any kind of external mechanical, electric or other known energy source, because for its propelling exploits only part of energy from moving water masses. Beside of energetic advantages, the present invention successfully solves problem of usually low water stream, because for difference of previously claimed and today known solutions, the new invention enables also successful operation even in very shallow water streams and because of absence of rising of driving blades, does not effect or endanger swimmers or vessels on the water surface. The new device by the present invention is easy to produce and because of smaller number of moving parts significantly more reliable during the long-term use. From the ecologic aspect the device by the present invention, does not affect on visual view on the river flow and landscape, because it is placed on the bottom of the river and it can not be seen from the coast. It also does not pollute the environment from chemical or mechanical ballast and because of very slow rotation speed, which does not exceed 4 turns per minute, does not affect fish offspring, i.e. for the flora and fauna of the water body. Self propelled hydrodynamic turbine of the invention solves the set of technical problems as follows: On its central axle receiving rotational torque from the system of at least two pairs or primary three pairs of radial rotating driving and ladle hands, by which half of each pair provides rotation of
whole system. One side of each pair provides propelling and the opposite side provides water ladle out, which is through hollow central axle transported to the coast. One half of single pair of the driving-ladle hands is by closed surface turned parallel to water stream and second, completely identical half is turned with open surface against water stream. In such case moving water masses could not cause rotation of the whole system, while hydrodynamic pressure is the same on both sides. Rotation around common centre is provided by the shape of driving and ladle hands, because they are made in shape of »U« profile with - horizontally - one closed and one open side. Open side of »U« profile is always turning against direction of water stream and on the opposite side of the hand water is pressing to the closed wall of the "U" profile. Even under such circumstances, the turbine placed in the water stream, would not be rotating. Therefore, final rotation provides single directional working valves (Check Valves), which are working on the way that while ladle hand is turning against water current, the Check Valve stays opened what causes centripetal flow of water in central placed drum and through hollow main axle in pipeline placed on the bed of water current and on the surface on the coast. During that, the open Check Valve reduces braking force on the ladle hand, which is turning against water current. At the same time the Check Valve on the opposite hand side is closed, while force of the water current is pressuring on the closed wall of the »U« profile. As described, on the opposite side of driving hand are formed larger water pressure and
force and that unbalance causes rotation of whole driving and simultaneously on water ladle out system.

present invention, with solenoid power generator built in common concrete base in third implementing case
Self-propelled hydrodynamic turbine of the present invention, which is in first implementing case shown on Figures 1/15, 2/15, 3/15, 4/15, 5/15 is made special for centripetal water capturing on each working hand, when turning against water current. Capturing of water, on working hands shown on Figure 1/15, allows their shape of typical »U« profile, by which is side 7 during water intake moving towards water current. When hand is moving towards water current opposite wall 8 is always closed and while on the inner wall 3 is attached Check Valve 2, which moving flap 1 water current holds opened. On the open wall 7 of »U« shaped hand are on known way attached carriers 5, which has beside mechanical stability also function of coarse filter, which does not allow intake of larger pieces of floating dirt in the water.
On the Figure 2/15 is shown the same ladle hand from horizontal view or as seen from the view of water current during water capturing.
On the Figure 3/ 5 is shown section of driving - water capturing part of self-propelled hydrodynamic turbine, which is composed from at least one pair or two on the opposite side lying driving - water ladle hands. In
priority there are three pairs of opposite lying hands, by which there are opposite lying hands in relation to each other turned for 180° on such way, that on water intake side wall 7 of body of the hand, is opened, and its pair on the opposite side wall 4 of body of the hand is closed for water current. All pairs of hands are on known way attached with upper cover 16 and lower cover 17, by which is on lower cover 17 attached central axle 20 with central and axial bore 12. In water placed device of the present invention, water effects on such way that on the driving side is made hydrodynamic pressure on opened wall 7 and in inner part of the wall 4 water current flows through opened Check valves 1 into closed central drum of the present invention. Imbalance of hydrodynamic pressures which occurs during process, causes turning of the whole construction and simultaneously brakes hydrostatic balance between forces, which effects on driving hands on one and water ladle hands on its opposite side.
On the Figure 4/15 is shown section of first implementing case of the present invention, where can be seen, that on water capturing part of the hand through the wall 7, water flows through Check valve 2 and by its opened flap 1 into central drum of the device, where is through axial opening 12 in axis 20, transported to radial opening 19 into central chamber 32 between bearings 18 and 18' and then to water outlet pipe 15, to the coast. During operation of the device it has on its driving side of the hand, Check valve 2 flap 1 lowered into lock position 10.
On the Figure 5/15 is shown enlarged cut section view of lower part of device of the present invention, which is in the area of chamber 32 casted in concrete plate 14 and it has both bearings 18 and 18' permanently lubricated and protected, by which are against water intrusion also protected by with air filled safety covers 21 and 21", which does not allow water to break into the bearings.
In second implementing case shown on Figure 6/15, is device of the present invention of first implementing case, additionally equipped with swinging flap 13, fixed on hinges 14 on outer and back side or driving side of each hand. Intention of each flap 13, is to increase driving effect of hydrodyna ic force of water current, because from the view of the incoming water current, flap 13 stays raised in horizontal position, by which is its movement on known way limited to angle a little bit less than 90°.
On the Figure 7/15 is shown driving - swinging flap 13 of the hand of the device in the second implementing case, where water current is coming from the opposite direction, what causes lowering of swinging flap to vertical position. Lowered in vertical position, swinging flap of the hand significantly enlarges propelling area of entire back part of the hand, where water causes hydrodynamic pressure.
On the Figure 8/15 in the second implementing case, is shown vertical section of hydrodynamic turbine on its driving - water capturing part with attached swinging flaps 13, which water current rises in horizontal
position. By that, flaps 13 create relatively small obstacle unlike on the opposite side lying flaps, which by its lowered position significantly enlarges propelling area, where water causes hydrodynamic pressure.
The second implementing case, is shown on Figure 9/15 also in vertical section, by which are all other elements identical as in first implementing case with exception of swinging flaps 13, which increases force what causes rotation of the device of the present invention.
On the Figure 10/15 is shown driving hand of the device of present invention in its third implementing case. Unlike the first two implementing cases, shown driving hand in its inner wall 3 does not have fixed Check valve. Next thing that differ is, that back wall 4 is not covering the whole radial length of the driving hand, but only covering its shorter part in priority closer to the center of the rotation of whole system. On the part of the hand where hinges 14 and 14' and swinging flap 13 are placed, there is no longer back wall 4 and it is by horizontally raised swinging flap 13 free flow of the water limited only on part where back wall 4 is fixed, under horizontal positioned raised flap 13 water flow moves smoothly.
On the opposite side placed driving hand, shown on Figure 11/15, the water current automatically lowers the swinging flap 13 into vertical position and by that closes free flow of the water current through the body of the driving hand and with that significantly increases propelling area where water causes hydrodynamic pressure.
On the Figure 12/15 is shown section view of self-propelled hydrodynamic turbine on its driving part, where smooth flow of water current through driving hands which turns against water current. Water is lifting the swinging flaps 13 to horizontal position, on the opposite side lying driving hands water lowers the swinging flaps 13 in vertical position and with that significantly increases propelling area where water causes hydrodynamic pressure.
On the Figure 13/15 is shown operation of the device of the present invention in combination of first and third implementing case, where because of low water speed current we want to increase power of rotation of whole system and also water pressure, which is captured upper turbine part of the device of the present invention, what is shown in first implementing case.
On the Figure 14/15 is shown combination first and third implementing case in addition with peristaltic pump, horizontally placed in concrete base 1 , which serves for increasing the pressure of captured water.
On the Figure 15/15 is shown driving part of device of the present invention in third implementing case, where device eccentrically drives solenoid power generator built in concrete base 11. Presented device of the present invention with addition of multiplier or gearbox for increasing of revolutions, can also drive submergible power generator of classic construction or different and known piston or centrifugal water pumps, built in concrete base 11.
