Description

SPECIFICATION

WIND TURBINE WITH PANEL ROTATING VERTICALLY AGAINST WIND

DIRECTION

The invention is related to wind tribune producing electric energy from kinetic energy of wind. The structure and results are completely different from the known condition of the technique and there are no similar ones of the invention. Disadvantages of existing propeller wind tribune are:

1- Total wind reception area of the paddles is very small.

2- Paddles converts a bit of the energy accumulated on the surfaces creating inclined plate into mechanic energy as rotating power.

3- Existing technology is not enough to extend the length of the paddles more, economically.

4- Installation cost and maintenance expenses are high.

Because of these reasons, it is impossible to improve existing technology in the propeller wind turbine.

With the invention, the purposes listed below have been wanted to be reached:

1- to convert whole of the energy accumulated on the plates into mechanical energy, By enabling plates utilizing drifting power of the wind to remain vertically against wind direction,

2- By applying dual and equal spinning power to the gear to which power is transferred in the gear groups used when providing power transfer between thin shafts having 90 degree angle between each other and which enables the power formed at turbine shaft to be transferred to alternator, it is aimed at minimizing friction and power loss. This invention is related to wind turbine with vertical rotating panel against wind direction.

Reinforced or metal round platform {1 ) is placed to the height determined at the place where the turbine is to be installed. An alternator room (2) is built under the Platform (1). Platform columns or feet (3) bear these (1 ,2). The feet (3) may be metal or reinforced concrete. Surface of the Platform (1 ) is in the shape of a circle and there is a platform (4) pipe on the center. One of the tasks of this pipe (4) is to enable the power obtained from the turbine to reach alternator room (2) by passing it through the pipe (4) with a shaft. Turbine installed on the Platform (1 ) is usually comprised of stainless metal. Turbine is on the Turbine bearing. Feet with bearing (5) under the turbine bearing stand on the platform (1 ) centered metal circle (6) there is a carrier center (7) on the feet with bearings. Bearing (8) on the mid of the carrier center (7) connects turbine bearing to platform pipe (4). There is no weight of turbine bearing on the pipe (4). If turbine drifts during strong winds, it holds on to the pipe (4) with this bearing (8). A gear set in motion by an electric motor with speed reducer placed on the platform (1 ) always rotates the turbine bearing above in the direction of wind. Turbine bearing rotates round the pipe (4) in the direction of wind and its feet with bearings always remains on the metal circle (6).

Bigger parts of turbine bearing are; top and bottom rail bearing (9), curved outer rail bearings (10), curved inner rail bearings (11 ), turbine shaft carrier (12) and main arms (13). Main arms (13) are connected to the top of bearing center below (7)

There is a horizontal turbine shaft (14) between shaft bearings (12) in front on the turbine turned to wind direction. Turbine shaft (14) always constitutes a right angle with wind direction. On the tips of Turbine shaft (14) are turbine shaft rotating gears (15). Turbine shaft (14) together with its bearings (16) is on shaft bearings (12). Shaft bearings (12) are connected to each other with belts (17) among them. There are two supplementary gears (18) on the last belt (17) with the cylinder shape. Supplementary gears (18) are connected to this last belt (17) with their bearings (19). Between Shaft bearings (12) are middle shaft carriers (20). Middle shaft bearings (20) support turbine shaft (14) with their bearings (21 ). Curved inner rail bearings (11 ) have been strengthened by being bound to number points of support belts

Turbine shaft rotating gears (15) and supplementary gears ( 8) are equivalent in terms of their teeth. Structure of these gears (15, 18) with bigger diameters is comprised of a Wheel comprising of profiles, a cylindrical surface with about 15 cm height which covers the Wheel and preferably fiber gears which are mounted on to this cylindrical surface. Connection between the gears (15, 18) has been provided with connection chains (23). Function of rotating gears (15) is to transfer the power coming from the chains (23) to turbine shaft (14). Diameters of Rotation gears (15) are long for lengthening the arm of momentum. In addition, this long diameter reduces friction resistance that the chain (23) will form.

Ί There are 3 flat-surfaced wind panels (24) with equal intervals on the chain (23). The panels (24) do not touch the chain (23). There is a certain distance between them.

Both of front and back surfaces of the thin wind panel (24) are covered with sheet and they are flat-surfaced. There are skeletal profiles (25) between these sheets. Panel shaft (26) goes through the mid of side skeletal profiles (25). Under the panel (24) is panel bearing (27). Tips of panel shaft (26) are locked into the bearings on the side profiles of the panel bearing (27). Rotation characteristic has been brought to the panel (24) with these bearings (28).

Under base tips of Panel carrier (27) are two curling bearings(29) for each. These bearings (29) bring curling characteristic to panel carrier (27) by rotating round carrier shaft (30). Bearings (31 ) on both tips of carrier shaft (30) shall activate in rail channels (32). Chain ear (33) is connected to the same shaft (30) with holding bearing (34).

Weights of wind panel and carrier (24, 27) have been transferred to the rails (32) with rail bearings (31 ). There are connection profiles (35) between Rails (32) and rail carriers (9). While chain (23) goes over gears (15, 18), rail outside (32) is connected to curved outer rail carrier (10), rail inside (32) to curved inner rail carrier (11) .

Only chain is connected to carrier shaft (30) with chain ears (33) holding bearings (34) with certain intervals in order to transfer chain (23) weights to rails (32). They are the supports (36) enabling panel carrier (27) to remain vertical on the carrier shaft (30). The supports (36) are connected to top tip of panel carrier (27) with curling bearings (37) from their top tips. Curling bearings (38) at the bottom tips of the supports (36) are connected to carrier shaft (30). Chain ear (33) is connected to the same carrier shaft with holding bearing (34). Weights of the supports (36) are transferred to rails (32) with carrier shaft (30). So rail channels (32) bear all weights between gears (15,18). Chains (23) do not bear weight, they only transfer the power applied by the drifting panel (24) to rotating gear (15). When Vertical flat panel (24) on the gears (15,18) in the turbine which has turned to wind direction, drifts by getting wind, it shall rotate the turbine shaft (14).

Angle between rail (32) and carrier (27) Panel carrier in the right triangle formed between curling bearing (29) and curling bearings of the support (37,38) is 90°. Top Acute angle of this triangle above is apical angle (39). While Panel carrier (27) and supports (36) are exceeding gears (15,18), length of the triangle base shortens. So apical angle (39) will start to get smaller and at the same time the angle which is 90° will start to increase. Curling bearings (29, 37, 38) enable Panel carrier (27) and supports (36) to pass through rail channels round the gears.

While a wind panel (24) being on supplementary gear (18) vertically against the wind direction is passing through the gear(18), it becomes parallel to horizontal plane at a point. If the position of the panel (24) does not change, after this point, it will face with an reverse wind preventing movement of the panel (24).

In order to prevent this air resistance from forming, it is always necessary to keep the panel (24) parallel to horizontal plane during its voyage between its horizontal while passing through rotating gear (15) position while passing through supplementary gear (18) and horizontal position. In order to reach this purpose, some additions have been made to panel carrier (27) and panel (24).

Before starting shape of Panel carrier (27), it is necessary to state dimensions of Turbine. Panel (24) height 7 m, length 20 m. Rotating gear (15) diameter 6 m. Supplementary gear (18) diameter 4 m. chain (23) length 66 m. Distance Between centers of Gears (15, 18) 25, 125 m. Parts of Chain: Chain top 25,015 m. Chain bottom 25, 185 m. Chain length on Rotating gear (15) 9,4248 m. Chain length on Supplementary gear (18) 6,2832 m. Distance between two panel carriers (27) 22 m. Distance between Panel carrier (27) and support (36) 3 m. Length and weight of the Panel (24) has determined the shape of panel carrier (27). Main parts of Carrier (27) are; side profiles (40), electric motor slots (41 ) and carrier base (42). It has Carrier base (42), top profile (43), bottom profile (44) and side (45) these (43, 44, 45) are connected to each other with support profiles (46) with certain intervals. Sides of these profiles (43, 44, 45) are covered with sheet (47). While Panel (23) is over gears (15, 18), top and bottom profiles (43,44) are the sides facing wind and they become a supplementary part of the panel (24) facing wind. Side profile (45) remains at the rear. When Panel (24) is under gears (15, 18) side profile (45) is always at the side facing wind and it reduces the carrier base's being affected from the wind. Top and bottom profiles (43, 44) always remain at the rear. Because Height, which top and bottom profiles (43,44) have formed, makes an effect which increases height of panel (24), heights of top and bottom profiles (43,44) must be subtracted from the height of panel thought. And the height remained must be found. There is panel shaft (26) at the middle of the height found.

Backs of Side profiles of Panel carrier (40) have been formed as isosceles triangle shape with sheet and wind effects during rotation have been minimized. Strong electric motors (48) have been placed to Motor slots (41 ). Motor with reducer (48) has one gear(49). Gears have been placed to Panel shaft (26) extensions. Motor Gear (49) and panel shaft gear (50) have been connected to each other with chain (51 ).

By taking diameter of supplementary gear (18) small, the length of the chain (23) to be used has been shortened. In addition, while panels (24) rotating from supplementary gear (18) are advancing through bottom rail chains, they move without forcing chain (23) because of 8% slope. This slope causes the panel (24) to deviate about 5° from horizontal plane and causes its front tip to remain below. This front tip has been lifted 10° upwards, and it is provided that acute angle between panel (24) and carrier (27) has become 80°. So, while panel (24) is advancing, it will take some wind from the bottom surface. It will have been provided that air molecules reflecting from the panel (24) above getting wind, affect the panel (24) below less.

When the Panel (24) coming from under gears (15, 18) to rotating gear (15) as parallel to horizontal plane comes to a point where it will lose its parallel state, motor (48) runs, rotates panel shaft gear (50), and protects parallel state of the panel(24). While Panel carrier (27) is rising, motor (48) continues to run. When Panel (24) panel carrier (27) are at the same plane, motor (48) stops running, vertical position lock pins (52) on panel carrier side profiles (40) open and they lock panel (24) from both sides, front and back. When Panel (24) rises over rotating gear (15) it will become vertical. When Panel (24) comes to vertical position while it is passing through supplementary gear (18), vertical position lock pins (52) close and free panel (24), and motor (48) runs and enables panel to remain in parallel position. While Panel carrier (27) descends motor (48) continues to run. When Panel (24) makes 80° acute angle with panel carrier (27 motor (48) stops running horizontal position lock pins (53) on panel carrier side profiles (40) open and they lock the panel (24) at two points. When advance of Panel (24) under gears (15,18) finish, lock pins (53) close and free panel (24) and motor (48) runs and enables panel (24) to remain at parallel position.

If the speed of wind increases and increases rotation speed of Turbine shaft (14) above the requested rotation speed, running motors (48) are stopped early while the panel (24) is passing through rotating gear ( 5) in order to reduce this rotation speed. And 60° lock pins (54) are opened from carrier side profiles (40) and the panel (24) is fixed from its both sides. At this stage, when panel (24) is over gear (15), acute angle between panel (24) and horizontal plane becomes 60°.

If speed of wind increases more and increases speed of rotation speed of shaft (14) again, running motors are stopped earlier while panel (24) is passing through rotating gear (15). And 45° lock pins (55) open and the panel (24) is fixed from its both sides. At this stage, when panel (24) rises over gear (15), acute angle between panel (24) and horizontal plane becomes 45°. 60° and 45° lock pins (54,55) reduces rotation speed of shaft (14) and enables turbine to run, protects panel (24) strong winds, and prevents the chain from being excessively forced.

If speed of wind increases more and more and endangers running of turbine, vertical position lock pins (52) does not work when panel (24) comes to the same plane with carrier (27) while panel (24) is passing through rotating gear (15). Motors (49) continue to run and enables panel (24) to remain parallel to horizontal plane. When the acute angle between Panel (24) and panel carrier (27) is 80° motor (48) stops running. Horizontal position lock pins (53) on Panel carrier side profile (40)opens and lock panel (24) at two points. At this stage, panel (24) makes about 10° angle with horizontal plane. So, panel (24) gets wind from below. However, when the speed of wind turns to normal, electric current is given to motors (48) of panel (24) which remains above the gears (15,18) and panel (24) enabled to come to vertical position. Turbine is started running.

When a panel carrier (27) turns one tour through rail channels (32), panel (24) will also have turned one tour round the shaft (26).

Motors (49) have one-way rotation and their running is regulated with electronic control system in coordination with Turbine shaft (14).

Thin shafts and gear groups have been used to transfer the power of Turbine shaft (14) to alternator room (2). Both tips of rotating shaft (14), rotates left top gear group (56), right top gear group (57) and vertical thin shafts (58). Left bottom gear group (59) and right bottom gear group (60) and horizontal thin shaft (61) are rotated. Horizontal thin shaft (61) transfers its rotation to bottom middle thin shaft (63) with bottom middle gear group (62). The position of this thin shaft (63) is not affected from Turbine carrier's turning round the pipe (4). This thin shaft (63) passes through platform pipe (4) and reaches alternator room (2).

There are shaft bearing (16), shaft break (64) and right top gear group (57) at the tip of turbine shaft ( 4). Other end of the shaft (14) is symmetric to this. Turbine shaft (14) is connected to shaft joint (65) after shaft break (64). Thickness of shaft joint (65) is equal to that of vertical thin shafts (58). This has been done to bring gear groups (56, 57, 59, 60) to Standard state. When it is necessary to be replaced, it makes it easy.

After Turbine shaft (14) rotates, power giving gear (66) of right top gear group rotates and activate the power receiving gear (67). In order to minimize the friction between these gears (66,67), equal force from both sides will be applied to the gear (67) receiving power. In order to reach this purpose, two gears are added to the gear group. These are transmission gear (68) and supplementary gear (69). Gear (66) giving power are connected to Turbine shaft (14) and it is fixed. When this gear (66) rotates, it rotates the gear (67) receiving power which touches itself and transmission gear (68). Transmission gear (68) transmits its rotation to supplementary gear (69). Supplementary gear (69) transmits its movement to the gear (67) receiving power. Rotation Direction of Supplementary gear (69) is reverse direction of Turbine shaft (14) rotation direction. Supplementary gear (69) sits on a radial bearing (70) over shaft joint (65). While Center of bearing is rotating with Turbine Shaft joint where it is connected and supplementary gear (69) will rotate reverse direction to these.

In order to strengthen the position of transmission gear (68) it has been taken on a radial bearing (71). This bearing (71 ) is connected to gear group box (73) with a bearing support (72). Pressure on transmission gear (68) shall be met by axial bearing (74) which it leans. Pressure on supplementary gear (69) shall be met by axial bearing (75) which it leans. Gear group box (73) is connected to Turbine shaft carrier (12) profile. The box (73) also harbors oiling of gears (56, 57, 59, 60). When gear (66) giving power rotates the gear (67) receiving power, these gears (68, 69) will rotate with delay because of gear gaps on the transmission gear (68) and supplementary gear (69) and supplementary gear (69) will not apply power to the gear (67) receiving power. In order to remove this gear gap, movement freedom in the parallel direction to the shaft (14) is brought to gear (67) receiving power. Movement of the shaft (14) on the vertical plane is prevented. Tooth height of gear (67) receiving power has been kept shorter than those of other gears (66, 68, 69) in order to bring this movement freedom. When Gear (66) giving power applies power to gear (67) receiving power, this gear (67) move away from the gear (66) giving power so much so that this gear (67) overcome gear gaps. Rotating powers at the both sides of the gear (67) receiving power balance. In short, the gear's (67) making Shaft (14) gain parallel movement provides this balance.

In order for the gear (67) receiving power to provide parallel movement to the shaft (14), it is also necessary for vertical thin shaft (58), which is connected to this, to move parallel to the shaft (14). Therefore, a special shape has been given to the bed (77) of vertical thin shaft (58) top radial bearing (76). Bearing bed (77) slips to spaces at its both sides with balls and it enables bearing (76) and vertical thin shaft (58) to move parallel to Turbine shaft (14).

Bottom tips of vertical thin shafts (58) sits on axial bearings (79). Axial bearing (79) also meets the weights of gear (67) receiving power and thin shaft (58) which gets power on, and pressure from adjacent gears (66, 69). There is vertical thin shaft bottom radial bearing (80) on right bottom gear group (60).

Horizontal thin (61) rotates with reverse direction against Turbine shaft (14). If Bottom middle gear group (62) gear giving power is at the same direction with right top gear group (57) gear (66) giving power, rotation direction of bottom middle thin shaft (63) is from left to right.

It should be thought that rotating alternator room (81 ) may be realized by taking Alternator room (2) onto carrier center (7). This choice shall increase the space of rotating room (81 ) which will shorten vertical shaft (58). It is not necessary for thin shaft to be passed through the pipe (4) in this choice. Horizontal thin shaft (6 ) turns at the shortest way and reaches alternator room (2).

The invention meets electric needs of all areas remarkably by running a number of Turbines. Turbines created to achieve the purposes of the invention are shown in the figures below:
