Description

Apparatus Floating on Surface of the water for Generating elecricity of Hydraulic power using Pumping out Water in Water Treatment plant and Filtration plant}

The present invention relates to a hydroelectric power generation apparatus, and more particularly, to a floating hydroelectric power generation apparatus capable of producing electric power by installing in a waterway through which a sewage treatment plant and a water treatment plant effluent flows.

Hydroelectric power generation, thermal power generation, and nuclear power generation are mainly used for generating electricity. These power generation methods are not only expensive, but also face environmental problems. In other words, hydroelectric power plants are constructed with huge facilities such as dams, and the turbines are operated by turning the turbines with the force of water drop. Therefore, the construction period is considerably longer and requires enormous cost and manpower. Thermal power generation has a problem that not only consumes a lot of fuel costs but also causes serious air pollution because the turbine is operated by turning a turbine into steam generated by heating water with fossil fuel. In addition, nuclear power is a steam generated by heating water with heat energy emitted during nuclear fission of uranium, and the generator is operated by turning a turbine, which makes it difficult to ensure the safety of radioactive leakage. It is a stumbling block.

On the other hand, in consideration of the problems of the existing power generation methods, research and development on various types of power generation methods using natural clean energy such as solar heat, wind power, geothermal power or tidal power as it is being actively progressed.

However, such a power generation method using solar, wind, etc. requires excessive time for payback period due to excessive initial investment cost, and it is accompanied by a disadvantage that it is impossible to achieve continuous power generation due to the weather. Normally, the utilization rate of solar power generation is about 12%, and the average operation rate of wind power generation is about 20%, so it is difficult to obtain continuous energy for investment.

Due to such deterioration of energy efficiency, it may be desirable to perform hydrophobic power generation in a facility in which a newly generated energy source is constantly flowing in water and relatively easy to manage in the external environment.

Examples of the facility where the water channel is formed include a farm, a water intake, a water treatment plant, and a sewage treatment plant. Examples of a facility that maintains a constant flow of water for availability include a sewage treatment plant or a water intake plant and a water treatment plant. The power generation method used in such a facility is usually used in the form of a drop, and if there is little or no drop, power generation is not possible. Therefore, an artificial dam, an embankment, or a water pipe is used to develop the drop. The above-mentioned scheme is not only owned by additional costs but may also be undesirable from an environmental point of view.

As shown in (a) process and (b) process of Figure 1, there are many processes that must be performed step by step in a general sewage treatment plant and water purification plant. Such a process involves the formation of a number of very long channels (W.L) in many forms for the purpose of drug disinfection or other purification, thereby transferring the water. The shape of the waterway (W.L) shown in the drawing is often configured by repeating the 'ㄹ' shape. However, at present, the water flowing in these channels has been left inadvertently flowing with little effort to convert them into energy sources. Therefore, it is necessary to develop a technology that can use the constant flowing water flow as an eco-friendly energy source without additional additional facilities such as banks and water pipes.

The present invention is to provide a floating hydrophobic power generation apparatus using sewage treatment plant effluent and effluent water from the sewage treatment plant that can produce environmentally friendly and stable power using the water flow unintentionally left in the waterway of the sewage treatment plant and water purification plant.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a process flow chart of a sewage treatment plant and a water purification plant in which a water channel is formed, FIG. 2 is a perspective plan view of the power generation apparatus of the present invention, FIG. 3 is a simplified plan view of the power generation apparatus of the present invention, and FIG. 4 is AA ′ of the power generation apparatus of the present invention. 5 is a sectional view taken along line BB 'of the power generation device of the present invention, and FIG. 6 is a view in which two power generation devices of the present invention are provided in a channel.

The present invention is a pair of floating member (10) disposed to float on the water surface on both sides of the waterway (W.L); A pair of cover plates 20 for wrapping and fixing the pair of floating members 10; A fixing plate 25 for fixing the upper surfaces of the pair of cover plates 20 to each other; A cylindrical aberration 30 disposed in the spaced space of the pair of cover plates 20; A power transmission unit 40 for transmitting the rotational force of the cylindrical aberration 30; A generator (60) configured to generate power by receiving power from the power shearing unit (40); A power controller 65 for converting and adjusting the power produced by the generator 60; Floating guide hole 50 provided in the upper edge region of the cover plate 20; And a plurality of floating guide frames 55 fitted into the floating guide holes 50.

According to the present invention, it is possible to continuously produce a constant power even with a change in flow rate by installing a power generator in an existing water channel having a flow rate without the need for a separate drop (5 to 10 m) for power generation, thus performing an operation rate of 90% or more. Can be. In addition, even if the same generator is repeatedly installed along the waterway, the power can be efficiently transmitted to the generator by the power transmission unit, and the floating guide frame is provided so that the rotational force of the aberration can be kept constant at all times. In addition, since the additional structure does not need to be installed as it is, the cost for producing electric power is reduced.

As shown in Figure 2 to 6, the power generation apparatus of the present invention to provide a floating member 10 on both sides of the water flow flowing along the waterway to always float on the water surface. As a material of the floating member 10, a light and low absorbent styrofoam is mainly used, and the floating member 10 is developed in large numbers for fishing and is also manufactured in various forms and marketed at low cost. In the present invention, by connecting a plurality of square products, a pair of floating members 10 are arranged on both sides of the channel. However, in addition to the styrofoam material, there are a variety of materials that can be utilized, such as a square plastic barrel that can maintain a certain buoyancy.

Since the floating member 10 disposed at a predetermined interval is weak in durability, the cover plate 20 having a high strength such as steel sheet is provided to surround the outside of the floating member 10. However, in addition to the steel sheet, a material such as high strength plastic may be used as the cover plate 20. The width of the cover plate 20 is larger than the width of the floating member 10 so that the power transmission unit to be described later is disposed inside the cover plate 20. That is, as shown in Figure 4, the floating member 10 is disposed on the right side of the space inside the cover plate 20 and the power transmission unit is disposed on the left side. In some cases, the cover plate 20 may be manufactured in a hermetic type to have a certain buoyancy and protect the power transmission unit from moisture. However, the manufacturing of the hermetic type requires an increase in manufacturing cost and precision in the manufacturing process. This may be undesirable because it is low.

 The fixing plate 25 for fixing the cover plate 20 to each other is provided on the upper surface of the pair of cover plates 20. The fixed plate 25 arranges the various devices necessary for power generation while providing a constant distance between the cover plates 20 or is provided for the convenience of the operator. In some cases, the fixed plate 25 may be manufactured by binding a plurality of rebars to the cover plate 20 by welding, but this is not preferable. The above-mentioned cover plate 20 and the fixed plate 25 may be manufactured to fit the width of the waterway, and when the width of the waterway is manufactured, the floating member 10 may be vertically spaced up and down depending on the water level. It is desirable to make the width slightly smaller so that it can flow.

The cylindrical aberration 30 is fixedly disposed between the pair of spaced apart cover plates 20. The cylindrical aberration 30 is fixed by inserting the rotating shaft 33 fixed through the central regions on both sides of the cylindrical aberration 30 into holes formed at both inner side surfaces of the cover plate 20, and a separate bearing device (not shown). ) Or sealing or the like. In the exemplary embodiment of the present invention, four cylindrical aberrations 30 are provided at regular intervals, but in some cases, one or two or more multiple aberrations 30 may be disposed. This can be determined by various factors, such as the length of the channel, the flow rate, or the amount of power generated by the hydropower generator. In addition, instead of manufacturing the entire aberration 30 in a cylindrical shape, only the side surface may be attached to the protrusion plate 31 to be described later. This means that as a means to reduce the weight of the aberration can be obtained a rotational force that is sensitive to the water flow as the weight is small, on the contrary, if the weight is heavy, the rotational force can be long lasting but not sensitive to the water flow. The weight adjustment of the aberration can be determined by appropriately adjusting the correlation between the durability and the rotational force transmission, such as a bearing or a seal for fixing the aberration to both sides of the cover plate 20. In the embodiment of the present invention, the operation is described through a cylindrical aberration.

Cylindrical aberration 30 is attached to a plurality of plate-like protrusions 31 at regular intervals perpendicular to the water flow direction along the cylindrical outer surface. A portion of the protrusion plate 31 is disposed to be submerged so that the water flow and the frictional force are maximized and the rotational force is maximized. In other words, rather than submerging the entire area of the protruding substrate 31, the submersion of some regions uses the principle of obtaining the maximum rotational force.

The rotational force thus obtained rotates the fixed rotating shaft 33 through both central regions of the cylindrical aberration 30. Bevel gears are attached to both ends of the rotating shaft 33 provided to extend to the inner side of the cover plate 20 to transmit the rotational force to the power transmission unit 40. In the embodiment of the present invention, but the bevel gear is attached to both ends of the rotary shaft 33 may be attached to only one side if necessary, which is a matter to be considered for proper transmission of power.

The power transmission unit 40 transmits the plurality of power transmission gears 41 and the power collecting unit 42 and the collected power to the generator 60 to collect the power transmitted from the power transmission gear 41 at a predetermined rotation ratio. It consists of a power converter 43 composed of a gearbox for. The power transmission unit 40 may be sealed with a gear box or the like to prevent damage by moisture. In the embodiment of the present invention, the power transmission unit 40 is provided on both sides, but the power transmission unit 40 may be configured only on one side or two power transmission units 40 may be configured diagonally.

The power transmission gear 41 is configured to convert the power of the rotating shaft 33 attached to the aberration 30 at right angles in the form of a plurality of bevel gears attached to the rotating rod shape. In the embodiment of the present invention, the bevel gears of the same type are engaged with each other where bevel gears attached to the rotary shaft 33 of the aberration 30 are disposed to transmit power at right angles. Another type of bevel gear is attached. Where gears intersect, gearboxes are provided to prevent gear corrosion and to prevent foreign matter from adhering.

Such bevel gears of the same type are called first bevel gears 44. The two bevel gears are attached to one rotating rod 45 to transmit power of two aberrations. Considering that the rotation of the cylindrical aberrations 30 disposed at intervals may not be smooth, there is an advantage that a constant rotational force can be applied to the power harvesting unit 42. However, the rotating rod 45 and the first bevel gear 44 may be provided according to the number of the cylindrical aberrations 30 to separately apply the rotational force of the aberrations to the power harvesting unit. The gear of the power transmission unit used in the embodiment of the present invention may be a bevel gear or another known gear, that is, a screw and a worm gear (not shown), etc., which may be another embodiment of the present invention. The first bevel gear may be attached to the power transmission gear 41 as many as the aberration 30 is arranged. Thus, even if a plurality of aberrations 30 are arranged in the long channel, power can be efficiently transmitted to the generator 60.

The power harvesting unit 42 is composed of second bevel gears 46 having different rotation ratios which are vertically engaged with the first bevel gears attached to the ends of the rotating rod 45 of the power transmission gear 41. The second bevel gear also collects the rotational force of the first bevel gear meshed from the opposite side. A circular rotary body 45 is attached to the end of the rotating rod of the second bell bell gear to transmit power to the power converter 43.

The power conversion unit 43 receives the power of the circular rotating body 47 by the timing belt 48 and transmits the gear ratio of the generator 60 turbine to another rotating body with a gear ratio installed immediately before the generator 60 turbine. To rotate it. In the embodiment of the present invention, the rotation speed was adjusted by using the timing belt 48 and the circular rotating body 47, and the generator 60 was provided with an increaser 49 in front of the generator 60 to adjust the rotational force.

The capacity of the generator 60 is appropriate according to the number of the aberration, the flow rate and the flow rate to be used, the power produced by the generator 60 is applied to the power regulator 65 is converted into a stable power that can be actually used and Adjusted. The power control unit 65 may install a remote control device (not shown) capable of remotely recognizing and controlling the presence or absence of an abnormality or the current power generation state when necessary by the administrator.

At each corner of the upper surface of the cover plate 20, a plurality of floating guide holes 50 penetrated in the vertical direction are provided. The floating guide hole 50 is a through hole into which the floating guide frame 55 to be described later is inserted, which is larger than the thickness of the floating guide frame 55, and in some cases, the floating guide frame 55 inside the floating guide hole 50. An auxiliary guide (not shown) may be provided to reduce friction with the.

The guide plate 55 allows the cover plate 20 and the fixed plate 25 to be moved by the floating guide frame 55 inserted into each of the floating guide holes 50 so that the floating guide holes can be fixed so as not to drift in the current. Floating guide frame 55 is fitted to each of (50). Floating guide frame 55 is preferably manufactured to a length enough to reach the bottom of the waterway, it may be fixed in some cases by using a piece or the like on the bottom of the waterway (W.L). As described above, the protrusion plate 31 of the aberration 30 always obtains a maximum rotational force of the aberration only when a certain part is submerged, so adjusting the degree of submersion is the above-mentioned injury guide hole 50 and the injury guide frame 55. to be. That is, when the water level is high, the cover plate 20 and the fixed plate 25 are raised upwards, and when the quantity is low, the projection plate 31 of the aberration 30 is always submerged only in a certain part of the water surface. Rotate to maximum torque. A floating stopper 59 may be provided at the upper end of the floating guide frame 55 to prevent the power generation device from being floated due to a sudden rise in water level.

In addition, the lower end of the plurality of floating guide frame 55 may be further provided with an auxiliary frame 57 for coupling with the lower end of another adjacent floating guide frame 55. By combining the auxiliary frame (57) with the lower side of the adjacent floating guide frame 55, respectively, to more firmly support the hydroelectric generator, and if the floating guide frame 55 is not fixed to the water channel, a separate fixing line (not shown) Suspend the hydropower unit to keep it in place at all times.
