NATIONALITY: A SUBJECT OF THE REPUBLIC OF INDIA.
The following Specification particularly describes & ascertains the nature of this invention and the manner in which it is to be performed:
The present invention relates to a vertical blade propeller for propelling boat/ship and related systems. Until now, propellers used for boat and ship propulsion are either screw propellers or paddle wheels.
Screw propellers are not efficient at higher speed, due to "Slip" between the
water and the propeller blades and "cavitation" effect.
Also, some energy is dissipated to provide radialy outward motion to surrounding
Paddle wheels are also not suitable for higher speed because of angle of the
blades entering & leaving the water, lot of energy is wasted in splashing and
lifting of water particles.
It is the object of the invention to have vertical blade propeller for propelling boat/ship to minimize power loss, by "Slip", cavitation and unnecessary motion of water.
Thus according to this invention, a vertical blade propeller for propelling boat/ship envisaged according to present invention comprises of series of blades mounted on connecting plate, which moves along with two levers rotating simultaneously with the help of common chain wrapped over two sprocket, which are mounted on the axis of both the levers.
Connecting plate is pivoted with two levers in such a manner that, the connecting plate will rotate along both levers keeping horizontal position while rotating.
Now the invention will be clearer describe with reference to Figs. 1 to 4 of accompanying drawings illustrating isometric view of Modified propulsion mechanism according to present invention.
DESCRIPTION OF DRAWINGS:
Fig 1 Illustrates isometric view of vertical blade propeller for boat and ship with
single connecting plate
Fig 2 illustrates isometric view of vertical blade propeller for boat and ship with
two connecting plates arranged parallel and 180° apart to each other.
Fig 3 illustrates isometric view of vertical blade propeller for boat and ship with
no. of connecting plates arranged in-between two parallel wheels rotating on
axes parallel to each other.
Fig 4 illustrates isometric view of vertical blade propeller for boat and ship with
two connecting plates arranged in line.
In Flg.l, bearing 2 and 10 are mounted on base 1 through this bearing 2, 10 shaft no. 3 & 11 are passed to the levers 4 &. 12. Lever 4 & 12 are firmly mounted on shaft 3 & 11. These shafts 3,11 are connected with each other with chain 9 & sprocket 8 & 13. This arrangement ensures simultaneous rotation of both levers. Connecting plate 6 is pivoted with help of bearing 5, 14 and pin 15, 16 due to this arrangement connecting plate 6 remains always parallel to the water surface while revolving. Blades 7 are mounted on the horizontal connecting plate 6, to produce maximum reaction by water in the revolving/reciprocating motion.
Fig.2 describes pair of vertical blade propeller arranged in a manner to balance in static as well as in dynamic condition. This arrangement ensures utilization most of the power in every rotation of the shaft. As described in fig 2 another connecting plate assembly 18 is pivoted by pins 16, 17 to levers 20 &19. Lever 19 &20 are mounted on shaft 11 &3. This mechanism is suitable for low cost human operated boats used either for fun, travel or transportation.
Fig 3 describes illustrating isometric view of no. of connecting plate assemblies arranged on P.C.D. to balance while revolving as well as in static position. Mechanism shown in fig 3 is compact. In this mechanism more than 1 blade is immersed in the water at a time, which results in more resistance to rotation of wheel, by water. This arrangement is made considering rotary power output of the engines. Wheel 31 &32 are parallel to each other, and rotates on separate axis, which are parallel to each other. Connecting plate assembly is pivoted to wheel 32 by pin 33 and to wheel 31 by pin 34. Both wheels 31 &32 rotate simultaneously by separate mechanism. This arrangement ensures horizontal position of connecting plate and vertical position of blades while revolving along with wheel 31 &32.
Fig. 4 illustrates isometric view of two connecting plate assemblies arranged in line to reduce unbalanced forces in static and dynamic condition. Chain 46 is fitted to engage with all four sprockets. Because of common chain provided to all four sprockets, it ensures balancing of connecting plates in static as well as in dynamic condition.
1. A vertical blade propeller for propelling boat and ship over water, wherein the system comprising any no. of blades (7) mounted on single connecting plate (6), which is pivoted at pins (15, 16) at both ends to two levers (4, 12) rotating simultaneously about their horizontal and parallel axes (3, 11) so that when one lever is rotated it rotates the other lever simultaneously and thereby automatically maintains vertical position of the blades (7).
2. A vertical blade propeller for propelling boat and ship as claimed in claim 1, wherein said levers rotate simultaneously with the help of the chain (9), sprocket (8,13) mounted on their shafts (11,3).
3. A vertical blade propeller for propelling boat and ship as claimed in claim 1, 2 comprising a pair of connecting plates arranged parallel to each other and 180° apart with common shafts (3,11) to balance forces statically and dynamically.
4. A vertical blade propeller for propelling boat and ship as claimed in claim 1, 2 comprising a pair of connecting plates arranged in line with common chain (46) and four sprockets to balance forces statically and dynamically.
5. A vertical blade propeller for propelling boat and ship as claimed in claim 1, 2 comprising any no. of connecting plates with single or multiple curved/ flat/ angular blades (35) mounted on each connecting plates, wherein the said connecting plates are pivoted to two round wheels (31, 32) on P. C. D. of each wheel, said wheels are parallel to each other and rotate on parallel axes (34, 36) to ensure vertical position of blades (35) while revolving.
6. A vertical blade propeller for propelling a vehicle over water like boat and ship substantially as claimed in preceding claims and as described herein with the accompanying drawings.
