BEST MODE FOR CARRYING OUT THE INVENTION

Prior to explaining the present invention, lift power and a hydraulic turbine are described as follows. Referring to Fig. 1, in accordance with a leverage action, great force is generated by means of small force when one end of the horizontal bar of a seesaw is alternatively moved up and down using lift power that is generated by means of a lift power motor. With regard to the leverage action, the following equation is established;

FL = F'L' (where F is the applied force, L is the distance from a fulcrum to a point of application, F' is the obtained force and L' is the distance from the fulcrum to the point where the force F' is obtained)

As known in the above equation, since the applied force and the distance from the fulcrum to the point of application are respectively in proportion to the obtained force and the distance from the fulcrum to the point where the force is obtained as known from the above equation, a force of 10 tons can be obtained at a point where the distance from the fulcrum thereto is 1 m. As a result, the turbine is rotated with the oil force of 10 tons with which the oil of the lift power hydraulic pump is discharged.

The lift power is concerned with force that is obtained at a position P' of a seesaw unit when the seesaw unit is supported by a center support post at a point A and force is applied at a point P.

An example is described in the following.

The torque T of a motor that has a power of 3 HP and is rotated at the number of rotation of about 1,800 rpm is 119.36 Kg tm . When speed reduction (speed reduction ratio is 60:1) is applied, the number of rotation of about 30 rpm and a torque of 7,162 Kg -c m are created. Therefore, the number of rotation is increased 60 times.

When the speed of the motor of 3 HP is speed-reduced through a speed reducer (its speed reduction ratio is 60:1), about 30 rpm can be obtained. When a seesaw unit is supported at a point A, and the distance L from a center support position to a position where the force are is applied and the distance L' from a center support position to a position where the force is obtained are respectively 5 m and 0.5 m, the force obtained at the point L' is as follows. HP = P -v/75=P τw/75

P-75 -HP/rw

P that is obtained in the above equation is;

P=75*3/5*3, 14 (w=3,14 rad/s) As shown in the above equation, the magnitude P of the force that is applied to the seesaw unit by the motor of 3 HP is 14.33 Kg.

When the force P of 14.33 Kg is applied to a point L that is spaced apart from a center support position by 5 m, the force P' of 143.3 Kg is obtained at a point that is spaced by 0.5 m. As known in the above equation, the obtained force by the distance from a center support position to a position where the force is obtained equals to the applied force by the distance from a center support position to a position where the force is applied. Therefore, when the force of 1 ton is applied to one end of a horizontal bar of 20 m, the force of 10 tons is obtained at a position where the distance from a center support position to a position where the force is obtained. As a result, the turbine can be rotated with the force of 10 tons of oil that is discharged from lift power hydraulic power.

Therefore, the electricity generating method of the present invention comprises seesawing a horizontal bar up and down around a center support post; providing means for seesawing the horizontal bar so as to generate lift power; generating high pressure oil by means of lift power hydraulic pumps connected to the seesawing horizontal bar; and generating electricity by means of rotation force that is generated by discharging to blades of a turbine high pressure oil generated by the lift power hydraulic pumps.

The hydraulic turbine has blades formed on the center or the left and right sides of the turbine shaft and contained in the casing of the turbine. The shaft traverses the casing of the turbine unit and is coupled to another shaft via a bearing. Packings are fitted to positions where the turbine shaft traverses the casing of the turbine unit so as to prevent oil from being leaked. The high pressure oil in the lift power hydraulic pumps is ejected to the casing from the high pressure oil accumulation unit to the turbine casing via the pressure regulating valve, and rotates the multistage blades of the turbine unit, thereby rotating the turbine shaft.

One or more lift power hydraulic pumps are respectively mounted to the side or sides of the seesaw unit so as to increase force and capacity.

The lift power hydraulic pumps are operated as follows. When the motors connected to both ends of the seesaw unit, lift power is generated in proportion to the capacity of the motors. This power is transformed to proportional force in accordance with the leverage action and is transmitted to the lift power hydraulic pumps. The lift power hydraulic pumps pressurize oil. The pressurized oil is ejected to turbine blades through a nozzle by means of high pressure accumulation unit and a pressure regulation unit, thereby rotating a turbine shaft.

A pressure pump connected to an oil tank supplies oil to the lift power hydraulic pump and the pressure of the lift power hydraulic pump causes a check valve to stop the inflow of oil. As a result, the inflow and outflow of oil is well performed.

On the other hand, the discharged oil is accumulated in a surge tank 280, is sent to the tank by means of a hydraulic pump 50, and is continuously supplied to the lift power hydraulic pump by means of a pressure pump 230.

The lift power is in proportion to the capacity of the motor that applies force to the end of the seesaw unit. The electricity generating apparatus includes lift power hydraulic pumps 50 suitable for desired capacity and flow rate, a high pressure oil accumulation unit 90 for accumulating high pressure oil generated by the lift power hydraulic pumps 50, a pressure regulating valve mounted to the outlet of the high pressure oil accumulation unit 90 for supplying oil at a constant pressure to the turbine, and a turbine unit consisting of a nozzle 200 and turbine blades 80. The lift power hydraulic turbine is provided at least for a pair of seesaw units so as to prevent force from being ceased. In order to increase force and the speed of rotation, two or more turbines constitute the lift power hydraulic turbine unit. The required energy for a pair of seesaw units is referred to as basic energy or a live coal. Energy generated in a pair of seesaw units is used for energy for operating the power plant.

Electricity generated in this way may be basic energy and a huge power planting station including second and third power plants can be operated using the basic energy, thereby allowing desired energy to be obtained. Referring to accompanying drawings, there is described the apparatus for generating electricity using lift power hydraulic turbines according to a preferred embodiment of the present invention in the following.

As shown in Figs. 2 to 5, the electricity generating apparatus comprises a seesaw unit 210 consisting of a horizontal bar 40 supported by a center support post 40 so as to be seesawed, a plurality of lift power hydraulic pumps 50 connecting the horizontal bar 40 with the center support post 40 and being squarely arranged, means 220 for seesawing the horizontal bar 40 so as to generate lift power of the lift power hydraulic pumps 50, and a turbine unit 140 having a generator unit, the generator unit generating electricity by the rotational force that is made by high pressure oil supplied by the lift power hydraulic pumps 50.

First of all, the center support post 40 consists of two connected bars. An upper support shaft 40-1, a center support shaft 40-2 and a lower support shaft 40-3 horizontally traverse the center support post 40 respectively at the upper, center and lower portions of the center support post 40.

Four pairs of lift power hydraulic pumps 50 are respectively positioned to connect the horizontal bar 60 of the seesaw unit 201 with the center support post 40 with the cylinders of the two pairs of lift power hydraulic pumps 50 rotatably and oppositely fixed to the upper support shaft 40-1, the cylinders of the remaining two pairs of lift power hydraulic pumps 50 rotatably and oppositely fixed to the lower support shaft 40-3, and the cylinder rods of the four pairs of lift power hydraulic pumps 50 rotatably and oppositely fixed to the left and right support shafts 60-1 and 60-2 of the horizontal bar 60.

The oil supply means comprises oil supply and discharge hoses 170-1, a pressure pump 230, manifolds 90-2 and an oil tank 240.

The oil supply and discharge hoses 170-1 are respectively connected to the manifolds 90-2 so as to supply or discharge oil, and the pressure pump 230 is connected to the manifolds so as to supply pressurized oil to the lift power hydraulic pumps 50.

The high pressure oil accumulation unit 90 comprises oil hoses 170-2 for accumulating high pressure oil from the lift power hydraulic pumps 50, manifolds 90-1 connected to the oil hoses 170-2, a tank connected to the manifolds 90-2 and a pressure regulator for regulating supplied oil to the turbines.

That is, since a plurality of lift power hydraulic pumps 50 discharge a great amount of pressurized oil, the pressurized oil is accumulated through the manifolds 90-2 and the oil hoses 170-2 and is discharged to rotate the turbine.

The bar seesawing means 220 comprises two cables 160, two pulleys 290 around which the remaining ends of the cables 160 are wound, two direction conversion devices 270 connected to the pulleys 290, two clutches 250 and motors 150.

The cables 160 are respectively connected to both ends of the horizontal bars 60 at their one side ends and respectively wound around the pulleys 290, the pulleys 290 are respectively coupled to the direction conversion devices 270 at their remaining side ends, and the rotation conversion devices 270 are respectively engagable to the motors 150 via the clutches 250. The clutches 250 may be electronic clutches or automatic transmission clutches and cause the pulleys 290 to be rotated in a normal direction or a reverse direction. The generator unit is constructed to be operated in such a manner that the high pressure oil is supplied from the high pressure oil accumulation unit 90 to the turbine having multistage blades 80 so that the turbine is rotated to generate electricity. The electricity is obtained by striking the blades 80 of the turbine with the high pressure oil. The central control unit is constructed to operate the clutches 250 so as to convert the direction of the rotation. According to the central control unit, a sensor is respectively mounted to an end of the horizontal bar 40 or the top of corresponding cushion pole 110. The central control unit operates the clutches 250 when the sensor senses the contact of the horizontal bar and the cushion pole.

The operation of the apparatus for generating electricity using a lift power hydraulic turbine is described in detail in the following.

First of all, in order to generate the seesaw action of the horizontal bar 60, the motors 150 of the bar seesawing means 220 are operated. The motors 150 transmit power to the pulleys 290 via the clutches 250 and the direction conversion means 270. One of the motors is operated to pull one of the cables 160. When one end of the horizontal bar 60 comes into contact with the cushion pole 110, the sensor senses this and transmits a sensing signal to the central control unit. In response to the sensing signal, the central control unit operates one of the clutches 250 and converts the direction of the rotation.

At this time, the direction conversion devices 270 are controlled by the central control unit so as to rotate the pulleys 290 in opposite directions. That is, one of the pulleys 290 pulls one of the cables 160 connected to one end of the horizontal bar 60, while the other of the pulleys 290 releases the other of the cables 160 connected to the other end of the horizontal bar 60.

According to the action of the seesaw unit 210, high pressure oil is generated by the lift power hydraulic pumps 50 squarely arranged, the high pressure oil is accumulated in the high pressure oil accumulation unit 90 through the manifold 90-1, and accumulated high pressure oil is supplied to the turbine at a constant pressure. Since the high pressure oil is supplied to the turbine at a constant pressure and strikes the blades 80 of the turbine, the vibration of the turbine is prevented and desired rotation ratio can be obtained, thereby obtaining electricity effectively.

Fig. 7 illustrates another method and apparatus for generating electricity using lift power hydraulic turbines according to another embodiment of the present invention. According to this embodiment, one cable 160 is connected to both ends of the horizontal bar 60 at its both ends and the cable 160 is moved by means of one bar seesawing means 220.

Both ends of the cable 160 are fixed to of the fixation portions of H- shaped auxiliary brackets at both ends of the horizontal bar 40 with the center portion of the cable 160 wound around the pulley 290 of the bar seesawing means 220.

The operation of the electricity generating apparatus as constructed above is described as follows. The motor 150 of the bar seesawing means 220 is operated. The motor 150 rotates the pulley 290 via the clutch 250 and the direction conversion means 270. While one portion of the cable 160 is pulled and the other portion of the cable 160 is released, the horizontal bar 60 performs a seesaw action. Cushion poles 110 are positioned under both ends of the horizontal bar 60 and a sensor is positioned on one of the tops of the cushion poles 110, so that the sensor senses that the horizontal bar 60 comes into contact with the cushion pole 110 and operates the clutch 250 and the direction conversion device 270 so as to convert the direction of the rotation of the pulleys 290. By repeating this action, the lift power hydraulic pump generates high pressure oil and rotates the turbine with the high pressure oil, thereby causing the apparatus to generate electricity.

Figs. 8 to 10 illustrate a further method and apparatus for generating electricity using lift power hydraulic turbines according to a further embodiment of the present invention. In the electricity generating apparatus, the seesaw unit 210 is integrated with the generator unit into a single body, the seesaw unit 210 having the horizontal bar 60 around the center support post 40, the generator unit generating electricity by operating the turbine unit 140 using high pressure oil generated by a plurality of lift power hydraulic pumps; a main body 300 consists of a concrete base 30 for fixing a ground structure, a steel structure 10 fixed in the concrete base 30, a generator unit 100 mounted a top of the steel structure 10 and provided with coils and a rotator, and a hydraulic turbine unit 140 having multistage blades 80 mounted to a rotating shaft of the generator unit 100; a seesaw unit consists of the horizontal bar 60 and a plurality of lift power hydraulic pumps mounted symmetrically mounted on the horizontal bar 60, so as to supply high pressure oil to the hydraulic turbine 140 and rotate the hydraulic turbine 140; and bar seesawing means 220 consists of a cable 160 connected to both ends of the horizontal bar 60, a pulley 290 around which a center portion of the cable 160 is wound, a direction conversion device 270 connected to the pulley 290, a clutch 250 connectable to the direction conversion device 270 and a motor 150 connected to the clutch 250.

The concrete base 30 is securely formed in such a way that a foundation is excavated in the ground and the concrete 20 is applied to the foundation while the steel structure 10 is positioned in the foundation.

The steel structure 10 is integrated with the center support post and the generator unit into a single body, and supports the main body 300 including the hydraulic turbine. As a result, since great load is concentrated on the steel structure 10, the steel structure 10 should be made of a strong material so as to withstand vibration and stress. The center of the seesaw unit 210 is rotatably fixed to the steel structure 10 by means of a shaft 120.

The main body 300 is mounted to the upper portion 40 of the steel structure 10. A high pressure accumulation unit 90 is positioned in a high position. A pressure regulating valve is mounted to the outlet of the high pressure accumulation unit 90 so as to eject high pressure oil to the multistage blades 80 of the turbine unit 140 through the nozzle 200.

Additionally, the turbine unit 140 is mounted to the center or the left and right sides of the turbine shaft 70. The shaft 70 traverses the casing of the turbine unit 140 and is coupled to another shaft via a bearing (not shown).

Packings are fitted to positions where the turbine shaft 70 traverses the casing of the turbine unit 140. The high pressure oil pressurized in the lift power hydraulic pumps is supplied from the high pressure oil accumulation unit 90 to the turbine casing via the pressure regulating valve, rotates the multistage blades 80 of the turbine unit 140, and is collected in the surge tank 280 through the oil outlet 180.

The pressure pump 230 is mounted so as to supply oil to the lift power hydraulic pump 50, enlarges flow rate and pressure, and is mounted to both sides of the turbine unit 140 to enlarge force and capacity.

Since the seesaw unit 210 receives a great amount of force at a support position of the steel structure and the lift power hydraulic pumps are mounted, it is made of multiple bars. The seesaw unit 210 is rotatably fixed to the steel structure by a shaft 120 at its center. The hydraulic pumps 50 are mounted to the seesaw unit 210. The bar seesawing unit 220 is connected to both ends of the seesawing unit 210 so as to actuate the seesawing unit 210.

The bar seesawing unit 210 includes the motor 150 so as to seesaw the seesawing unit 210 by repeating the pulling and releasing of the seesawing unit 210.

The lift power hydraulic pumps 50 are between the main body 300 and the bar seesawing unit 210 by means of hinges 190 so as to be freely actuated. The number of the lift power hydraulic pumps 50 may be varied so as to enlarge their capacity.

A main tank 240 distributes oil and stores oil for supply. The pressure pump 230 is mounted to the main tank 240 so as to supply oil to the lift power hydraulic pump 50.

Oil is collected again after it is supplied to the turbine unit and transforms its energy to mechanical energy. The surge tank 280 is mounted to a lower position so that oil discharged after rotating the turbine shaft 70 can be collected. The pressure pump 260 is provided for sending the oil to the main tank 240. The components are connected to each other by means of oil hoses or pipes. There is described the operation of the electricity generating apparatus using the lift power hydraulic turbine in detail.

The motor 150 is operated to seesaw the horizontal bar 60 of the seesaw unit 210. The oil in the lift power hydraulic pump 50 mounted between the main body 300 and the horizontal bar 60 of the seesaw unit 210 is pressurized. The pressurized oil is sent to the high pressure accumulation unit 90. The oil discharged from the lift power hydraulic pump 50 that is mounted to both sides of the horizontal bar 60 of the seesaw unit 210 is ejected from the high pressure accumulation unit 90 and the pressure regulating valve to the turbine blades 80 through the turbine nozzle 200, thereby rotating the turbine shaft 70.

In Fig. 10, a plurality of lift power hydraulic turbines constitutes a lift power hydraulic turbine unit. In order to regulate power, the central control unit regulates the rotational speed of the motor, pressures, the discharge flow rate of the pressure regulating valve by means of a variety of sensors.

As shown in Fig. 11, a lift power hydraulic turbine of yet another embodiment includes a turbine having a reciprocal cylinder unit instead of the turbine blades. The reciprocal cylinder unit consists of a turbine shaft 70' formed of a crank arm, a cylinder 75 and a piston. As the horizontal bar 60 of the seesaw unit 210 is seesawed, the lift power hydraulic pump discharges high pressure oil and pressurizes the piston in the cylinder, thereby pressurizing the piston. As a result, the piston is actuated up and down and rotates a turbine shaft 70', thus allowing the apparatus to obtain electricity.
