(Figures-1, 2)

(Figure-4)

The sieve paddle impeller (1), which transfers the flow energy of the river to the device, is mainly consists of the following elements; a long cylindrical impeller body (19); circular impeller body covers (20) that cover both ends of the impeller body (19) and to which a plurality of sieve paddles (21) are mounted; a plurality of sieve paddles (21) that are connected to the impeller body covers (20) with bolts (54) at both ends, with a sieve structure arranged at equal angles around the impeller body (19), exposed to minimum water resistance while entering and exiting the water, single or multi-row flexible paddle (22) mounted on the end portion of the sieve paddle (21) from one end, the other end is idle, covers the surface of the sieve paddle (21) exposed to the current and transfers the flow energy to the sieve paddle (21) that limits itself; impeller air gap (23) that enables the impeller (1) to float on the water; paddle ring (55), where the sieve paddles (21) are connected with bolts (54) from their distant ends relative to the impeller shaft (2) and ensures that the paddles (21) are motionless. (Figures-3, 4)

The eccentric arms (6, 7) most basically consists of the following elements; arm bearing (33) that allows each arm (6, 7) to be connected to the impeller shaft (2) via a wedge (34); arm shafts (28, 29) that allow ropes (8, 9) to be connected to the other end of each arm (6, 7). (Figures-4, 5)

Right arm shaft (28) mainly consists of the following elements; arm shaft roller (35) that allows the right rope (8) to be connected to the rotating right arm shaft (28) with minimal friction; arm shaft roller bearing (59) containing the arm shaft roller (35) and to which the right rope (8) is connected.

(Figure-6)

Left arm shaft (29) mainly consists of the following elements; arm shaft roller (35) that allows the left rope (9) to be connected to the rotating left arm shaft (29) with minimal friction; arm shaft roller bearing (59) containing the arm shaft roller (35) and to which the left rope (9) is connected.

(Figure-6)

As the positions of the right arm shaft (28) and left arm shaft (29) change with respect to the cylinder center (24), the sum of the distances of the arm shaft centers (31, 32) from the cylinder center (24) also change. When the arm shaft centers (31, 32) are on the axis no I., the sum of the distances of the arm shaft centers (31, 32) to the cylinder center (24) is maximum. When the arm shaft centers (31, 32) are on the axis no

II., the sum of the distances of the arm shaft centers (31, 32) to the cylinder center (24) is minimum. The change in said length sums shows that the sum of the lengths of the ropes (8, 9) is required to be changed. The rope spring (36) located inside the piston (5) changes the sum of the lengths of the ropes (8, 9). (Figures-7, 8)

When the arm shaft centers (31, 32) are on axis no I., the right rope head (40) shall contact the spring housing right cover (38) and the left rope head (41) to the spring housing left cover (39). In this case, the total length of the ropes (6, 7) and the piston (5) is maximum. When the arm shaft centers (31, 32) are on the axis no II., the rope spring (36) pulls the unloaded rope head towards the loaded rope head. (Figure-8)

The piston (5) that provides the pumping of water is mainly consists of the following elements; rope spring (36) that provides elongation in the length of the ropes (8, 9); spring housing (37) that houses the rope spring (36); spring housing cover (38, 39) that limits the elongation of the rope (8, 9) and allows the rope (8, 9) to pass through it. (Figure-8)

The right rope (8) is connected from one end to the right arm shaft (28) by means of the arm shaft roller (35) and the arm shaft roller bearing (59). The right rope (8) enters into the cylinder (4) by passing through the cover hole (46) on the cylinder right cover (12) with the 90 ° orientation of the right rotating reel (26). The right rope (8) is connected to the rope spring (36) inside the spring housing (37) placed in the center of the piston (5) by means of the right rope head (40). The right rope head (40) can move back and forth within the spring housing (37). The spring housing right cover (38) is connected to the right end portion of the spring housing (37) preferably with a threaded fastener and limits the movement of the right rope head (40). (Figures-4, 8)

The left rope (9) is connected from one end to the left arm shaft (29) by means of the arm shaft roller (35) and the arm shaft roller bearing (59). The left rope (9) enters into the cylinder (4) by passing through the cover hole (46) on the cylinder left cover (14) with the 90 ° orientation of the left rotating reel (27). The left rope (9) is connected to the rope spring (36) inside the spring housing (37) placed in the center of the piston (5) by means of the left rope head (41). The left rope head (41) can move back and forth within the spring housing (37). The spring housing left cover (39) is connected to the left end portion of the spring housing (37) preferably with a threaded fastener and limits the movement of the left rope head (41). (Figures-4, 8)

The rotating reel (26, 27) mainly comprises the following elements; the reel bearing (44) that moves the reel (45) always towards the arm shaft center (31, 32) and fits on the cover reel shaft (43); reel shaft (47) that connects the reel (45) to the reel bearing (44); the reel cap (48) through which the rope (8, 9) passes and provides the reel (45) to turn to the arm shaft center (31, 32). There is a reel cap hole (49) on the reel cap

(48) through which the rope (8, 9) passes. (Figures-9, 10)

The flow energy of streams or tidal streams is transferred to the paddles (21) of the impeller (1) floating on the water or submerged. The rotational motion of the impeller (1) is transferred to the eccentric arms (6, 7) placed opposite to each other at both ends of the impeller shaft (2). The rotational movement of the eccentric arms (6, 7) and the shafts (28, 29) at the end portion of the same is transferred to the piston (5) as a back and forth motion by means of the ropes (8, 9) to which they are connected. The device is a mechanism that transforms the rotational into back and forth movement with this feature.

(Figure-4)

While the left arm shaft (29) moves away from the cylinder (4), the piston (5) approaches the cylinder left cover (14). The water available in the volume (13) between the piston (5) and the cylinder left cover (14) passes through the left pressure check valve (18) and is connected to the pressure collector (25). In the meantime, water is sucked into the volume (11) between the piston (5) and the cylinder right cover (12) through the right suction check valve (15). (Figure-11)

While the right arm shaft (28) moves away from the cylinder (4), the piston (5) approaches the cylinder right cover (12). The water available in the volume (11) between the piston (5) and the cylinder right cover (12) passes through the right pressure check valve (16) and is connected to the pressure collector (25). In the meantime, water is sucked into the volume (13) between the piston (5) and the cylinder left cover (14) through the left suction check valve (17). (Figure-12)

Water is pumped from the cylinder (4) twice in one full revolution of the impeller shaft (2).

Today, cylinder-crank-piston rod mechanism is widely used so as to transform rotational motion to back and forth motion. These systems are useful and also expensive. When the capacity becomes larger, the size and cost also increases. The reason for this is that the cylinder is in the vertical position to the rotating crank.

In the present invention, the cylinder (4) is parallel to the rotating impeller shaft (2). The piston (5) stroke can be increased by increasing the size of the eccentric arms (6, 7).

Since the motion transmission is provided by means of the ropes (8, 9) and the reels (26, 27) that orient the ropes (8, 9), the cost is very low. (Figure-4)

Another characteristic of the invention is that it adjusts its own level according to the changing water level. The water weight equal to the volume of the impeller air gap (23) must be more than the weight of the device so as to make level control by the device. In this case, the impeller (1) will float on the water and the sliding base (3) to which it is engaged, depending on the level; moves forward and upward in case the level increases, backward and downward in case the level decreases. In any case, the cylinder (4) will always remain in the water.

(Figure-1)

The sliding base (3) mainly consists of the following elements; two sliding base slides (52) sliding on two ramp slides (51); two cylinder clamps that allow the cylinder (4) to be fixed on the base slides (52) from the ends; two impeller shaft bearings (42) that enable the impeller shaft (2) to be mounted on the base slides (52) from its end parts in a movable manner.

(Figure-13)

The sliding base limiter (57) fixed on the ramp slide (51) limits the movement of the sliding base (3) and prevents the cylinder (4) from touching the streambed. (Figure-13)

The base slide lock (60) prevents the base slide (52) from coming out of the ramp slide (51). (Figure-14)

The present invention can generate electricity by means of a water turbine (62) and electricity generator (63). The stream powered water pump transfers the pressurized water to the turbine (62) by means of a pipe (64) and allows the turbine (62) to rotate. The electricity generator (63) connected to the turbine (62) generates electricity. A tank filled with air (65) is connected to the system with the tank connection pipe (66) so as to prevent the pressure fluctuations in the water. (Figure- 15) Industrial Applicability of the Invention

The stream powered water pump, which serves the above-mentioned aims, can be produced and used in any field of the industry and is applicable to the industry.
