Technical Field

The present invention relates to a pump generator, and more particularly, to an efficiency-improved pump generator capable of converting water stored in an upper portion into electric energy as much as possible while minimizing loss.

Korean patent registration No. 10-1062246 (registration of 30/8/2011; hereinafter referred to as "prior document 2") proposes a turbine for hydroelectric power generation. Prior art document 2 is a turbine for a hydroelectric power plant, which includes: a pair of first sprockets mounted on a first rotating shaft at a predetermined interval, the first rotating shaft having a gear at one end thereof; a pair of second sprockets mounted on the second rotation shaft at a predetermined interval; a pair of chains mounted in a closed loop on the first and second sprockets; a belt fixed on an outer surface of the chain; a plurality of drip trays are arranged on the outer surface of the belt along the circumferential direction of the belt, the drip trays are flexible, and flexible cables are installed on the edges of openings in the drip trays.

Detailed Description

Hereinafter, the present invention will be described in detail by preferred embodiments. However, the present invention is not limited to the embodiments described herein, and may be embodied in other forms. Are provided to ensure that the matter herein described is thorough and complete and will fully convey the spirit of the invention to those skilled in the art.

Fig. 1a is a block diagram of a pump generator according to the present invention.

As shown in the drawings, the pump generator 10 according to the present invention includes an upper tank 20, an aberration device 30, a generator 40, a lower collection tank 50, and a simple power generation device 60.

The upper tank 20 can pump water in the lower water pump or store rainwater by using a small amount of consumed midnight electricity, partially drain river water to a larger falling area, or combine these methods to make fresh water. The upper tank 20 is formed with a discharge port on one side to discharge the stored water in one direction, and an intermittent valve is installed in the discharge port to control the discharge of the water, and a propeller, a simple rotary shaft, and a simple generator are installed on a discharge line by converting the discharge pressure into electric power to be supplied to a power line or to be stored in a separate charger.

The aberration device 30 includes upper and lower rotation shafts 31 and 32 and a circulation belt 33 installed at upper and lower portions, respectively, through a main body frame. The upper and lower rotating shafts 31 and 32 are arranged in a plurality of rollers of a predetermined diameter or one large-diameter roller, or a plurality of small-diameter rollers are arranged on the same axis to rotate the endless belt, so that the rotation and direction change of the endless belt can be performed.

In addition, sprockets 311 are installed at both ends of the upper and lower rotating shafts 31 and 32, and chains 331 corresponding to the sprockets are coupled to the endless belt 33 to receive power from the endless belt, thereby being rotatable.

The circulation belt 33 is rotated downward by the load of water in the upper tank, and rotates the upper and lower rotation shafts. The circulation belt is formed with a load transmission device for receiving a load of water.

For example, the load transmission means forms the accommodating buckets 332 having the accommodating spaces at predetermined intervals in the longitudinal direction of the endless belt 33. At this time, at the position where water is supplied from the upper tank 20, the opening portion of the receiving tub 332 is directed upward so as to easily make fresh water of the supplied water, and is lowered by the gravity of the fresh water to rotate the circulation belt 33 in one direction.

In addition, the receiving tub 332 is formed of an elastic material to be rotated by the upper or lower rotation shaft to facilitate shape deformation when the traveling direction is changed, and only the opening inlet portion is formed of a metal material so that the inlet is easily secured when receiving water.

In addition, as shown in fig. 2, a chain 331 coupled to the endless belt 33 may be integrally formed on an inner surface of the endless belt 33 such that the upper and lower rotating shafts are rotated together while the endless belt is lowered.

Next, the generator 40 is connected to the upper rotating shaft 31 or the lower rotating shaft 32 to generate electric power by rotation. The generator 40 preferably generates electricity at a desired rotational speed through a transmission or a decelerator, rather than being directly connected to the upper or lower rotating shaft. In addition, the electricity generated by the generator may be supplied by various known methods, such as regulating the voltage by a transformer and then supplying to the power system, or stored in a charger for use when needed.

The lower collection tank 50 temporarily collects the water when the endless belt rotates and then discharges the water. That is, the water stored in the upper tank 20 moves the circulation belt 33 while being lowered by the aberration device 30, and the moving circulation belt rotates the upper rotation shaft 31 or the lower rotation shaft 32, and the generator 40 generates electric energy in a power generation manner using potential energy by using the rotational force. Here, the water, which moves the circulation belt downward, is discharged from the storage tub 332, collected in the lower collection tank 50, and discharged to the outside through the discharge pipe 51 formed in the lower collection tank.

The simple power generating means 60 is installed on the discharging pipe 51 of the lower collection tank, and generates power by the rotation of the discharged water.

such a simple power generation device 60 includes a propeller 61, the propeller 61 being rotated by a discharge pressure and installed in a duct; a simple rotating shaft 62 connected to the propeller and drawn out of the tube; a simple generator 63 for generating electricity by the rotational force of the simple rotational shaft.

FIG. 1b is a top view of the discharge pipe of the lower collection tank cut horizontally. As described above, the propeller 61 is formed in the discharge pipe 51 to be rotated by the discharged water. The propeller is formed to have the same size as a vertical section of the discharge pipe and forms a rotation axis at a rotation center, or is rotated by placing the propeller only at a lower side of a main discharge flow passage of the duct to receive discharge pressure by enlarging a portion where the propeller is formed.

In addition, the simple rotation shaft 62 is connected to the center of the propeller and pulled to the outside of the duct to transmit the rotation force of the propeller to the outside of the discharge duct. Therefore, one or more propellers may be installed in the discharge pipe of the lower collection tank, and a simple rotation shaft may be installed in each propeller to convert the discharged pressure into a rotation force.

The simple rotation shaft 62 is connected to a simple generator 63 to generate electricity, and when a plurality of simple rotation shafts are formed, a simple generator is installed on each simple rotation shaft to generate electricity, or electricity can be generated by one simple generator 63 by being concentrated on one simple rotation shaft through a separate pulley or sprocket. In addition, the simple rotary shaft may be directly connected to a simple generator to transmit a rotational force, or converted into a desired number of revolutions using a transmission, and then generate electricity.

in addition, the power generated by the simple power generation device 60 may be supplied to a power line through a transformer, or may be charged in a separate charger 90 to be used as an emergency power source for emergency use or driving a pump generator.

In the configuration as described above, in order to make the water stored in the upper tank used for maximum power generation, the aberration device may be further provided with a leakage water collector 70.

As shown in fig. 3a and 3b, a leakage water collector 70 surrounding the circulation belt's accommodating tub 332 is further installed in the upper side of the accommodating tub 332 for supplying water from the upper tank 20 to the circulation belt 33 in the aberration device, and the leaked water is resupplied to the accommodating tub located at the lower layer in the process of filling water with the accommodating tub so that it can be converted into rotational energy.

The leakage water collector 70 is fixed to the upper portion of the aberration device, and both side walls and the front wall are integrally configured to have a U-shaped horizontal end fixed by a fixing frame 80. At this time, the fixing frame 80 is provided in a fixed form at one side of the main body frame for supporting the upper or lower rotating shaft 31 or 32, or is installed separately from the main body frame to install the leakage collector near the discharge pipe of the upper tank.

The rear end of the horizontal end of the leakage collector 70 is close to the front surface of the circulation belt 33, that is, the surface formed with the receiving tub 332 is closely arranged to close all sides, and the receiving tub is supplied with water while passing through the inside to ensure the receiving tub is filled with water.

The leakage collector 70 forms a curved surface to direct the lower portion of the inner wall toward the flow path of the receiving tub of the circulation belt such that the curved surface of the inner surface of the leakage collector 70 is guided when leakage water occurs, and the leakage water is supplied through another receiving tub located at the lower layer of the receiving tub and then stored. Therefore, the receiving tub 332 fills 60% to 80% of the inner space to form a free space only after receiving water from the upper tank 20, and then finishes descending after further storing the leaked water guided by the leakage collector 70.

The leakage trap 70 has a collector body 71 consisting of two side walls and a front wall, which has a U-shaped horizontal end. The lower portion of the collection body 71 is formed in a smooth curved surface toward the inside so that the leaked water generated in the process of receiving the water into the receiving tub is guided to the inside along the inner curved surface after being collected, thereby being received in the receiving tub of the lower stage.

As shown in fig. 4a and 4b, a piezoelectric element is further installed at the pump generator according to the present invention to convert the load transferred to the leakage collector into electricity through the piezoelectric element.

The leakage collector 70 is further provided with collecting connections 72 projecting horizontally on both sides of the collecting body and with a striking rod 73 as a vertical through-rod. A plurality of the collecting links 72 are formed in upper and lower sides of both sides of the collecting body 71 and are connected by the fixing frame 80 and the springs 74. In this way, when the spring 74 is connected through four points at both sides, when water is received in the receiving tub 332, the leaked water hits the collection body 71 of the leakage collector, so that the leakage collector moves forward, backward, left and right, and up and down. In this case, if the piezoelectric element is attached to a position where the leakage water collector moves, vibration generated by the leakage water collector may be converted into electricity.

In addition, the fixing frame 80 for fixing the leakage water collector 70 is installed by inserting the striking rod 73 of the leakage water collector, and the side piezoelectric elements 82 are installed perpendicularly to the front, rear, left, and right on the inner surface and the approaching portion of the striking rod such that the striking rod 73 strikes the side piezoelectric elements 82 when the position is moved to the x-axis and the y-axis, thereby generating electricity.

In addition, the fixing frame 80 protrudes the latching protrusion 83 at a lower portion of a predetermined interval at a portion where the striking rod 73 is located, and by horizontally mounting the lower piezoelectric element 84 on an upper surface of the latching protrusion, when the leakage collector moves up and down, a lower end of the leakage collector strikes the lower piezoelectric element 84 to generate electricity.

The leakage collector 70 is connected to the spring 74 by a fixing frame 80. That is, the collecting link 72 is formed at upper and lower portions of both sides of the leakage collector, and the fixing connection piece 81 is integrally formed in the fixing frame, and by connecting the collecting link 72 and the fixing link 81 with the spring 74, the leakage collector 70 can be changed in position even by a small shock, thereby striking the side piezoelectric element 82 or the lower piezoelectric element 84 to generate electricity. In addition, since the leakage water collector 70 can be moved by wind and hit the side or lower piezoelectric elements 82, 84 in addition to the vibration caused by the leakage water, the wind energy can be used for small amount of power generation.

In addition, since the leakage water collector 70 is suspended from the fixing frame 80, it is preferable that the fixing connection piece 81 is disposed at an upper portion and the collection connection piece 72 is disposed at a lower portion to be connected by the spring 74. In addition, as shown in the drawing, the striking rod 73 and the fixing frame 80 may be formed in a circular shape in cross section or in a square rod body, so that the side piezoelectric element can be easily mounted and struck.

In addition, the electric power generated by the side piezoelectric element 82 and the lower piezoelectric element 84 can be directly transmitted to the power supply line, but since the amount of generated electric power is small, the charger 90 is used after completing charging, or is used as an emergency power source or a facility driving power source.

The pump generator 10 of the present invention configured as described above accumulates water, rainwater, or pumped water from a nearby river channel in the upper tank, discharges the water along the length range, lowers the discharged water by the aberration device, and converts the potential energy of the water into rotational energy to generate electricity.

In addition, the power generation and discharged water is collected in the lower collection tank, and during the discharge, simple power generation is performed to generate additional power.

In addition, in supplying water from the upper tank 20 to the aberration device, particularly, the receiving tub 332, a leakage water collector 70 is further installed to collect the leaked water and re-supply it to the receiving tub of the lower layer to supply power.

In addition, the leakage water collector 70 is installed in a form capable of moving left and right and up and down when being struck by the spring 74, and vibration generated when vibration is generated by a leakage water collecting process or wind strikes the piezoelectric element to further generate power while minimizing potential energy of water stored in the upper tank and maximizing power generation.

In addition, by increasing the height of the pump generator of the present invention, or by arranging a plurality of pump generators one above another, the water stored in the upper tank is lowered by the plurality of pump generators, particularly, the aberration device, so as to produce maximum electricity by using limited water resources.
