Description

BLADED WATER WHEEL
The technology field
A technical desing concerns a construction of a blade water wheel for top water with radial entry of driving water.
Background art water wheels used up to now either single-stage or multistage, applying both positional and moving power of water for driving of connected generators of electric power,are always constructed so that stable fixed blades or buckets are fixed on the outer periphery of the impeller wheel. Becose of their relativery low efficiency, in many cases they are replaced by variously constructed turbines. Their common shortage which significantly restricts their use especially in case of small water streams is their constructional complexity, technical deman- dingness in installation as well as in operation which does not counterbalance the economic diadvantages in their improved efficiency.
Disclosure of invention
The mentioned disavantages of the ,up to now used water wheels are signi icantly removed by the designed technical solution which principles consists in that a rotor of the water wheel consists of a rotor body in form of a laid empty closed roller fixed in a centric way on a horizontal shaft, while on the outer side of the rotor body envelope wall tilting formed blades are placed on pins are in parallel with the rotor shaft axis, by one end in a rotational way along the axis of pins. A radius the inner side curving of the tilting formed blades is identical with a radius of the external side of the wall of the roller envelope of the rotor body and which width is only a little less than the height of the roller body of the rotor.A horizontal shaft of the blade water wheel is placed ina rotational way in lateral walls of the stator body of a form of the laid U. Its upper open part through which driving water enters forms an entrance channel, round roller part of stator forms a working channel and the lower open part of the stator which discharge water from from the water wheel forms an exit channel. The end of the lower side /bottom/ of the entrance channel is closely adjacet to the external side of the tilting formed blade which inner side is closely adjacent to the external envelope surface of a rotor roller bod .A maximum length of radius of a roller part of stator which axis is identical with an axis of shaft of the blade water wheel is the same as a sum of the length of radius of a roller body of rotor and height, of the tilting formed blade. Lateral sides of the stator are formed by solid parallel walls and their inner sides of walls are sitated in a distance from each other which is identical with the height of a roller body of rotor,or it is a little biger.
A blade water wheel according to the presented technical design is significantly more efficient compared to the up to now water wheels while its construction is still easy and operation is not demanding. A reason is especially a continuously produced positive torque daring rotation of rotor which is given by a difference of a centre of gravity of tilting formed blades in both limit positions working, when a free end of the blade is supported on its edge by the inner surface of working channel wall, and not working, when the inner side of the blade is adjacent to the external area of the rotor roller body envelope. .• The improved afficiently is achieved also due to the hydrostatic water upward pressure which contributes to rotation of formed blades into a working position. The hydrostatic water upward pressure is proportional to the size of volume of blade. On the contrary, the weight of blades actively contributes to tilting the blade into a not working position.
Brief Deskription of Drawing
A demonstrated performance of a blade water wheel according to the presented technical design is schematically provided from a side view in Fig. 1.
A blade water wheel consists of a roller body 1 of rotor, on which external side of envelope 4 tiltin.ςf formed blades 2 are placed on pins ^ rotationally around the pin axis * A roller body 1 of rotor is fixed on a horizontal shaft J. rotationally placed in side walls of rotor of the laid U form. The upper open of stator consists of an entrance channel 5. which feeds driving water into a blade water wheel - in direction of an arrow. The end of the lower side 6 /bottom/ is closely adjacent to a formed blade 2 which inner side is adjacent to the external side of the evelope 4 of t >tor 1.
The roller part of stator forms a working channel 8 and the lower open part of stator forms an exit channel serving for water discharge.
The blade water wheel work is based on the following principle : The driving water supplied through the entrance channel _ starts immediately after enterning the working channel 8 of stator act by its formed blade 2 and contribute to its complete tilting into a working position and starts to rotate the rotor. The formed blade 2 in a complete working position is supported by its free end adge to an internal side of the working channel 8 of stator and adjacent lateral sides to inner sides of lateral sides of stator. Thus the working channel 8 is sealed and both positional and moving power of the driving water is fully transmitted to formed blades 2, roller body 1 of rotor and horizontal shaft 7 of the blade water wheel.
As soon as the rotor partially rotates and formed blade 2 leaves the area of the working channel 8 a way for free discharge of water into an exit channel ^ is provided. Continuing rotation of the rotor causes gradual tilting of the formed blade against a direction of discharged water intoa not working position and reaching the lower side 6 of the entrance channel, it is completely adjacent by its inner side to the external surface of envelope 4 of the body 1 of rotor. This cycle is continuously repeated.
Industrial applicability
The blade water wheel according to the presented technical design can be applied especially for small water streams for driving of connected generators of electric power.
