movie video - unusual water wheel in motion

The device according to pictures (1) and (2) consists of the wheel (1) which is equipped with leaks (7) for floats (2) on four sides. Floats (2) that have smaller density than water are equipped with canals (3). The wheel (1) tightly passes through the cut in the barrier (4) which divides the tank (5) into two parts.

There is a water-level on one side which is marked „water“, at point of the water-wheel top margin (1) an on the other side at point of the water-wheel centre line (6) eventually lower. The water supply (E) into the tank (5) is abreast with the higher water-level and the water drain (F) from the tank (5) is abreast with the lower water-level. There are floats (2) in quadrants (A) to (B) put out of float leaks (7), therethrough the water breaks through the leak (3) under the bottom of the float (2). Limitation of the float disconnection (2) may be performed e.g. by the wire connecting the float bottom (2) with the float leak bottom (7). There is a water lift working on disconnected floats (2) which carries over the wheel and tries to rotate it in accordance with the marked rotation arrow.

There is a water gravitation force working on the wheel (1) in quadrants (B) to (C) placed under the disconnected floats (2) and disconnected float (2) working on the wheel (1) within the same meaning as floats in sectors (A) to (B). In quadrants (C) to (D) there are floats pushed by the water pressure into leaks (7) in the wheel (1). In quadrants (D) to (A) there are floats (2) inserted in wheel (1) leaks (7). Putting the floats (2) out and in is being periodically repeated and the wheel (1) is rotating in accordance with the marked rotation arrow.

In the first photo, there is an uplift water-wheel with partly disconnected floats and barrier and a in the other one a functional model of the uplift water-wheel in the tank. It´s an assembly of so-called „water closed circuit“ during which the water from the space with lower water-level is being pumped over by the submerible pump into the space with higher water-level. The submerible pump delivery is regulated by the electronic controller so as to keep requested water-level diference. This configuration is useful for implementation of exams with water-wheel.


In the picture below there is an alternative of an unusual water-wheel in construction with prismatic floats. Floats in the form of prism with a narrow squarish base provide indispensable benefits in comparison with cylindrical floats.

There is a possibility to place more floats and herewith boost output and uniformity of the water-wheel rotation on the four sides of the water-wheel.

In case of great deal of influent water due to which the water-level rises up above the level of the water-wheel contour and water overflows the wheel then these floats may serve as traditional water-wheel paddles. On the other hand in case of the influent water-level drop-off the high efficiency of the water-wheel still remains.
