Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a curtain water-

The present invention relates to a method and a device for constructing a hydraulic turbine, which is a hydraulic turbine rotating along parallel upper and lower wire ropes in a parallel, upper and lower wire rope in flowing water (seawater) (Sea water) flowing in a long parallel upper and lower wire ropes is relatively large, and a lot of electric power is generated at the same time.

 In the era of increasing energy problems due to the global environmental crisis, the need for the development of alternative energy and the utilization of renewable energy is getting bigger.

 New and renewable energy uses bio, solar, hydrogen, wind power and so on. However, various kinds of power generation are limited in terms of facility and scale, and efficiency is generally low.

 In case of hydropower or algae development, deep water (sea water) should be used, so the columns are built deep and the turbine blades are winged (two or three horizontal wings) because of the resistance of the flowing water Because it is small in width and can not be made long, it needs to be made strong, so that only a few% of the cross sectional area of the incoming water (sea water) is made to be applied to the wing and the efficiency is low. The column is large and sturdy Is required. This means expensive and limited facilities.

 In the case of existing hydropower and tidal power generation, there is a problem that the area of water (sea water)

 There is a problem in that it is limited to other new and renewable energy generation facilities, the structure is complicated, and the manufacturing cost is high.

 SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a water turbine and a tidal turbine, The upper and lower wire ropes of the same height, or less, or more, and the parallel upper and lower wire ropes are firmly connected horizontally to each other between the steel towers, and between the two opposing parallel upper and lower wire ropes, (Water), which is a water turbine, is fixed to the upper and lower parallel ropes in a vertical manner, and the kinetic energy of the water (sea water) To maximize the receiving cross-sectional area of the water (sea water) flow so that the water (sea water) The purpose of the present invention is to provide a curtain power generation device that converts most of the energy of water (sea water) into electric energy and simultaneously performs a lot of power generation.

 In order to solve the above-mentioned problems, the present invention provides a curtain water-power generator comprising: a turbine blade having a plurality of curved blades rotated by water (seawater) flowing at a speed from the outside; And the parallel upper and lower wires are connected to each other at an upper pillar end and a lower pillar at an upper pillar end and a lower pillar respectively and the upper and lower parallel wire ropes are pillar- And the generator body, which is several tens to several hundreds of hydro turbines, is installed between the parallel upper and lower wire ropes in such a manner that the generator body is tightly fixed to each other perpendicularly to the parallel upper and lower wire ropes However,

 In the operation portion, the integral turbine blade that rotates downward is connected to the lower shaft by a bearing, the lower shaft is bolt-fixedly coupled to the parallel lower wire, the integral turbine blade is fixedly connected to the shaft on the opposite side, The generator frame is coupled to the shaft fixed to the generator frame. The generator frame is coupled to the shaft by a bearing, the lower portion of which is in the direction of the integral turbine blade, and is bolted to the upper portion of the upper portion parallel to the upper portion. And is fixed to the upper and lower wire ropes in a hanging parallel state.

 In this case, since the rotating integrated turbine blade rotates the magnet at the end of the shaft, electric power is generated by the magnetic flux generated by the coil installed inside the generator frame, and the electric power is stabilized through the connected converter to be outputted to the electric current line And collecting the generator currents from the respective converters to transmit electricity to the transmission line. Here, tens or hundreds of generator bodies are fixedly installed between parallel upper and lower wire ropes in the form of hanging to receive water (seawater) like a folding screen that blocks water (seawater).

 In addition, it is possible to prevent leakage of foreign matter, water, and the like by packing the outside of the bearing and the outer surface of the bolt fixing part for the power generating unit.

 The present invention further provides a high pillar and a pylon for receiving more water (sea water) in the water, and further comprises a fixing wire connected to the upper pillar and a concrete anchor embedded in the bottom (bottom) surface from the end of the pylon have.

 According to the present invention, when the water (sea water) flows in the water, the kinetic energy of the water (sea water) is rotated in the water (sea water), and the integrated turbine blade is rotated. The rotating magnet of the turbine is rotated to generate electric current in the coil in the generator frame fixed to the upper wire, and the electricity is stabilized through the converter and sent to the transmission line. In this case, the whole of the generator, which is vertically suspended from the parallel upper and lower wires and fixedly coupled to the wire in a straight line with the integral turbine blades, becomes a single generator body, and therefore, the generator body is made up of several tens to several hundreds Because it is vertical, it spreads like a folding screen, so a large amount of power can be generated between parallel upper and lower wires.

 In addition, the integrated turbine blades rotate because of the weak water (sea water) flow (less than 1m / s per second), and it is supported by parallel upper and lower wires with strong strength and can generate electricity. . In addition, it is possible to efficiently generate electricity even if water (sea water) flows in any direction.

 Further, since the generator body is vertically fixedly coupled to the upper and lower wires in the form of twisted strands of a plurality of strands, it is possible to maximize the generation area for receiving water (sea water) without relation to the torsional moment. It is safe that the packing prevents the foreign matter from flowing in the original way, and it is convenient to separate and repair the generator body during repairing. In other words, it is easy and convenient to repair and replace frequently all the time because it is possible to replace some of the generator and parts with bolts by loosening them. Moreover, bearings have a fixed lifetime and should be replaced frequently, which makes it very easy.

 According to the thickness of the upper and lower parallel wires, the wire can be installed very long, and the long facility can withstand the strong water (sea water) flow. Therefore, one parallel upper and lower wires can be made very long, so that the generator body can be made into several tens to several hundreds or more facilities, and the receiving area of water (seawater) can be enlarged. This is of course possible within a range of sufficient tension along the upper and lower parallel wires, which is also possible because the upper and lower parallel wires may have different thicknesses.

 Thus, in order to make the area receiving the flow of water (sea water) more effective and more, the upper and lower parallel wires can be radially or net-shaped so that the water (sea water) flow can be efficiently utilized.

 In this way, the existing water turbines are limited and water (sea water) receives less than a few percent of the diameter, and the facility can be replaced with a relatively large and expensive one compared to the power generation. In other words, the existing horizontal turbine (turbine) is a turbine that does not have a percentage of the rotating sectional area of the incoming water (seawater) and receives more than 90% of the rotating sectional area. It is wasteful (the turbine blades occupy only a few percent of the area of the diameter). This is very low compared to the large facility costs. However, the curtains with parallel top and bottom wires produce a variety of turbine blades Because it is a cylindrical type, it can be made big and long. It can generate more than 50% of water (seawater) flow cross-sectional area. It is a power generation facility using parallel upper and lower wires having a very large tension. ) It is possible to generate several tens to hundreds of times more electricity than the power turbine. In other words, it can cover the wide area of blowing water (sea water), and it is possible to develop intensively and to develop the water (sea water) almost to stop the flow. Therefore, the efficiency compared to the existing water (Zhao) power generator is several times to several hundred times superior.

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

 A curtain water-power generation apparatus 100 according to an embodiment of the present invention will now be described with reference to FIGS. 1 to 9. FIG.

 1, 2, 3, 4, and 9, a curtain water power generation apparatus 100 according to the present invention includes a double column curtain water power generation apparatus 200, a three-column curtain water power generation apparatus 300, The power generator unit 10, the shaft 20, the turbine blade unit 30, the lower shaft 40, the wire unit 50, the support unit 60, the wire 70, , And a steel tower (80).

 The steel tower 80 sufficiently supports the parallel upper and lower wires 71 and 72 and withstands the weight of the generator bodies 10 resting on the parallel upper and lower wires 71 and 72, The upper and lower parallel wires 71 and 72 are sufficiently pulled by the fixed wire 81 to be able to be pulled sufficiently. (Bottom) 84 of the concrete is anchored to the concrete anchor 83 so that the parallel upper and lower wires 71 and 72 can withstand the tensile force. The upper and lower wires 71 and 72 having a plurality of parallel strands of steel can be thickened to have a strong strength and the buried concrete anchor 83 deepens the depth of the buried concrete 84 It is possible to have a strong tension.

 Here, the turbine blade unit 30 is always capable of generating electricity only when water (seawater) flows. That is, the double column curtain water power generation apparatus 200, the three-column curtain water power generation apparatus 300, and the multi-column curtain water power generation apparatus 400 can always generate electricity when water (seawater) flows.

 The above power generation can withstand the earthquake with the strong tension of the upper and lower parallel wires (71, 72), so it can develop well.

 In the first configuration, a long strand or wire bundle in the form of a twisted wire of a high columnar shape supported by a steel tower 80 and a steel bundle at a lower end, that is, parallel upper and lower wires 71 and 72, And the lower end is connected to the lower end at both ends, and the generator body 10 is vertically suspended on the parallel upper and lower wires 71 and 72 as shown in FIG. 1, and the generator frame 12 is directed upward. Make sure that the gaps are close enough so that they do not hit each other. Then, most of the energy of the water (seawater) is used by maximizing the area that corresponds to the incoming water (seawater). In other words, curtain-type power generation that can receive the maximum amount of water (sea water) is possible.

 When separating and assembling, make sure to use heavy equipment such as crane or water for repairing. It is possible to repair the generator body 10 by replacing the generator body 10 with a single set. But also to a large tensile force according to the thickness of the upper and lower wires 71 and 72 in parallel. The upper and lower wires 71 and 72 have a strong tensile strength to hang suspension bridges, which is advantageous in that they can withstand large loads and loads.

 As shown in FIG. 5A, when the generator body 12 is turned upwardly and the packings 16, 17, 25, and 46 are processed into the generator body 10, water (seawater) And the torque due to the rotation of the turbine blade portion 30 is transmitted to the upper portion of the generator body 10 in parallel with the upper and lower wires 71, 72 so that the torque is not affected. That is, the torque is canceled by the parallel upper and lower wires 71 and 72, so that the torque is not affected by the torsional action due to the rotational force. It is possible to install dozens to several hundreds of the generator body 10 on a long line of parallel upper and lower wires 71 and 72, The electricity of the converter current line 55 coming out of the generator body 10 is collected by the transmission line 52 and the transmission line 52 is installed along the upper wire 71. [ As shown in FIG. 9, the power transmission line 52 is fastened to the water (seawater) without being shaken by the current line fastener 56 in the middle.

 The generator body 10 further provided according to the strength of tens to hundreds or parallel upper and lower wires 71 and 72 on the long line of the parallel upper and lower wires 71 and 72, And the upper and lower wires 71 and 72 parallel to the high column supported by the iron tower 80 can be connected to two or three or more places to maximize the receiving area of water (seawater) . Particularly, when the receiving area of the water (sea water) flow is increased by using a plurality of parallel lines of the upper and lower wires 71 and 72 as a plurality of lines, the parallel upper and lower wires 71 and 72 are radially or meshed It is possible to maximize the receiving area of the flowing water (seawater) and to make the best development. In this case, it is possible to develop enough to stop the water (sea water) corresponding to the receiving area of the incoming water (sea water). Therefore, the best development is made possible in the development of underwater water. As shown in Fig. 2, the structure is such that the direction of the flowing water (seawater) can be developed even when the direction of the flowing water differs in different directions according to time.

 The steel tower 80 is supported by the fixed wire 81 on the opposite side in a plurality of strong supports as shown in Fig. 8 to give a strong tension to the wires 71 and 72, and a large and durable buried cone click anchor 83 is mounted on the underside 84) to have a large tensile force.

 Here, the generator body 10 will be described in detail with reference to FIGS. 5A, 5B, 5C, 5D, 5E and 5F.

 5A, the generator body 10 includes a turbine blade 30 and a generator frame 12, and the two turbine blades 30 and the generator frame 12 are coupled to each other by a shaft 20 , The shaft 20 is fixed to the turbine blade portion 30 in the shape of a hollow center and is fastened by the turbine blade fixing bolt 34 and the magnet 21 is fixedly coupled to the opposite side. The inner side of the turbine blade 30 is engaged with the thrust bearing 44 and the roller bearing 45 and is fastened to the lower shaft 40 and sealed with the packing 46 as in Fig. The lower shaft 40 coupled with the thrust bearing 44 on the inner side of the turbine blade 30 and the roller bearing 45 has a length of the lower wire 72 to prevent torque on the lower wire 72, The wire fixing cover 41 is fixed to the lower wire 72 with the bolts 43 by the wire fixing grooves 42 while the generator body 10 is fixed in a shape perpendicular to the lower wire 72 . Then, the lower shaft 40 is firmly fixed to the lower wire 72. The generator frame 12 on the right side is coupled to the shaft 20 to which the magnets 21 are fixedly coupled to each other by a thrust bearing 22 and a roller bearing 23. [ In the interior of the generator frame 12, the generator coil 51 is fixedly coupled to the generator frame 12. The transformer current line 55 is out of the outer portion of the generator frame 12 and is packed 16 as shown in FIG. 5A. A seal 25 is sealed between the bracket 13 and the shaft 20 coupled with the generator frame 12. Inside the generator frame 12 is disposed a coil 25 for converting the current from the generator coil 51, And a converter 53 connected to the current line 54. Electricity generated due to the magnetic flux change in the generator coil 51 due to the rotation of the magnet 21 flows into the coil current line 54 and enters the converter 53 The current from the converter 53 is collected to the transmission line 52 through the converter current line 55. The generator frame 12 on the upper wire 71 side is connected to the upper wire 71 The wire fixing lid 11 is fixed to the upper wire 71 with the bolts 15 by means of the wire fixing grooves 14 while the generator body 10 is formed in a shape perpendicular to the upper wire 71 The generator frame 12 is fixed to the upper wire 71 firmly. C. The thrust bearing 22 in the generator frame 12 is tightened and tightened with the bracket 13 to support the shaft 20 and the gap between the bracket 13 and the shaft 20 is sealed with a packing 25 . Packing (17) is applied between the bracket (13) and the generator frame (12).

 The integral turbine blade (31) can be manufactured using a relatively strong and lightweight metal material or a carbon composite material, and it is sufficient that the material is durable in water (sea water). 5e and 7a as shown in FIG. 5e and FIG. 7a, but it forms a curved surface and can receive the kinetic energy of water (seawater) as much as possible and can make the number of wings appropriate. The integral turbine blades 31 can be made to have an arbitrarily large diameter to receive the area of water (seawater) as much as possible. In addition, since the integral turbine blade 31 has a large cylindrical shape, it can be made longer in the longitudinal direction and can be made longer than 10 m to withstand the bending strength, thereby maximizing the receiving area of water (seawater).

 The operation principle of the integral turbine blades 31 will be described in detail since the integral turbine blades 31 are the most important part to receive water (sea water) energy. The manufacturing method is the same as described above. As shown in FIG. 7A, the diameter portion width 38 of the action of water (seawater) is the area that is received by the integrated turbine blade 31 as a whole, (Sea water) passing through the turbine blades, which are projected to the opposite side, but only the turbine blades 37 are rotated by less than 50% of the area of the integrated turbine blades 31 because the integrated turbine blades 31 are rotated by the kinetic energy of the shaft 20. [ Apply pressure to this opposite turbine blade. The integral turbine blade (31) rotates due to the difference in drag coefficient of the blade bent in the shape of a saw tooth. When the parallel upper and lower wires 71 and 72 have a very long length so that the power generation is good and the water is fully received as curtains and the remaining water (sea water) energy passes backward, (Sea water) energy can be converted into kinetic energy. Particularly, in the case of the integrated turbine blades 31 of the net, the water (sea water) can be almost stopped to be generated. This is similarly explained by the fact that low-lying mountains and trees almost completely depress the wind. The integral turbine blades 31 are integrally formed by inserting a turbine blade shaft 32 made of steel into the inside as shown in FIG. 5E, in order to manufacture the integral turbine blades 31 with a high strength. The integrated turbine blade 31 made of a metal material or a carbon composite material having a strong and light weight is made strong so as not to separate from the turbine blade shaft 32 and a bearing jaw 33 is provided to support the thrust bearing 44 . The shaft 20 is fixed to the shaft 20 by the turbine blade fixing bolt 34 while sealing the inside by processing with the adhesive assembly 35 between the shaft 20 and the integrated turbine blade 31 during the assembly thereof, A bolt fixing groove 24 is provided so that the generator body 10 is not separated by a tensile force or a compressive force. The packing washer 39 for fixing bolts maintains the airtightness of the turbine blade fixing bolt 34. And the packing 46 is processed for sealing with the lower shaft 40.

 The lower shaft 40 is provided with a thrust bearing upper retaining ring 47 and a thrust bearing lower retaining ring 48 to withstand tensile and compressive forces as shown in Figures 5b and 5f.

 A roller bearing (23, 45) is mounted on the above rotating body to support the roller bearing (23, 45).

 Therefore, the generator frame 12 and the lower shaft 40 are firmly fixed to the parallel upper and lower wires 71 and 72 so that only the rotation of the integral turbine blades 31 is permitted even in strong external physical environment, .

 The flow 36 in the water (sea water) of FIG. 2 shows the flow direction of a specific water (sea water) when it changes with time.

 Since the flow of water (seawater) forms a large load (resistance), the auxiliary fixing wire 82 can be provided on the upper and lower wires 71 and 72 as shown in Fig.

 9 shows a circuit of the wire section.

 The energy converted into the kinetic energy of the shaft 20 by rotating the integral turbine blade 31 in this way is fixedly coupled to the generator frame 12 by rotating the magnet 21 fixedly coupled to the shaft 20 And acts on the generator coil 51 to generate electrical energy by magnetic flux variation. This electricity generates alternating current to improve transmission. The alternating current is stabilized through the converter 53 and then collected by the transmission line 52. The electricity collected in this way can produce electricity of several megawatts and gigawatts, which is very large current, because there are many generators. In particular, water (seawater) has a specific gravity of 1, which is 1000 times larger than air (1 m3 of air is 1.02 kg, whereas 1 m3 of water is 1000 kg). The energy of the flowing water (seawater) Which is 1000 times larger than the wind of the air. That is, since the kinetic energy is E = 1 / 2mv 2, a large mass of energy can be generated and power can be developed. In particular, if the integral turbine blades 31 are made long in a cylindrical shape, the strength of the integrated turbine blades 31 is much stronger than that of the blades of the horizontal axis turbine.

 At this time, the flowing water (seawater) can generate electricity steadily at a speed of less than 1 m / s or more, so it is possible to generate power anywhere in the water and current.

Very large generation facilities are possible by maximizing the area that receives the flow of water (gigawatt)
