Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bi-directional tidal current generation system,

In general, tidal power generation is a method of generating electricity using the flow of seawater. Unlike tidal power generation, where a breakwater is installed on the coast by using the tide difference, it is a power generation system that uses turbines installed in the sea using ocean currents without installing dams or breakwaters in the waters where fast seawater flows. Since there is no need to construct a breakwater, it is considered to be environmentally friendly because it is less costly than tidal power, is free to ship, does not interfere with the movement of fishes, and does not affect the surrounding ecosystem.

However, the conventional algae power generation requires a large construction cost, the operation of the facilities is not easy, and the natural environment is greatly damaged, thereby causing environmental pollution.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a bidirectional algae power generation system using an induction structure according to the present invention will be described in detail with reference to the accompanying drawings.

First, the present invention proposes a structure for guiding the flow of algae in a reef tangent to the sea to make a waterway to increase the flow rate of the algae, and then to generate electric energy using the aberration.

In Figs. 1 and 2, one side of the waterway 10 is a place where the sea and the flow of the algae are arranged in parallel to each other. That is, the water channel 10 should be a place where it is easy to direct the sea water according to the flow of the algae. Thus, the reef (1) should be a place where birds, ie tidal and ebb tide, are not disturbed by terrain or other structures. Furthermore, it is preferable that the water channel 10 is formed where the flow of the algae is strong as in the case of the Uldolmok. The water channel 10 is formed at a constant distance from the reef 1 at a constant distance and the inlet 11 and the outlet 12 of the channel 10 are formed to be wider and narrower. Therefore, the water channel 10 is a relatively narrowed passage for the channel 11 between the inlet 11 and the outlet 12 and the channel 10 between the inlet 11 and the outlet 12.

The induction structures 40 and 41 are installed at an angle from the inlet 11 and the outlet 12 of the channel 10 to collect the flow of seawater by the algae toward the channel 10 to increase the flow rate. The induction structures 40 and 41 may be installed in various forms according to the geographical conditions of the reef 1 in which the waterway 10 is formed. In addition, the induction structures 40 and 41 may be constructed of a concrete slab, a block stone, a tetrapod, or the like, or a mixture of an upright material or a mixture of an upright material and an upright material, have. In addition, a structure in which the lower ends of the inductive structures 40 and 41 are fixed to the seabed and the upper portion is lifted and lowered along the sea surface by buoyancy may be applied.

3A and 3B, the aberration 20 is fixedly coupled with a plurality of vanes 22 at a plurality of end portions 23 provided in a cylindrical shape and spaced radially from the central axis 21 at regular intervals. At this time, the blade 22 may be made of a metal or a resin plate, or may be made of a cloth woven with synthetic fibers so that the weight and corrosion of the aberration 20 are minimized and consumable.

A plurality of grooves 23 connected to the center axis 21 of the aberration 20 are installed and the aberration 20 is formed into a cylindrical shape in which a large number of grooves 23 are formed as necessary to form a large divided segment, 23 and 24 are fixed and supported by a plurality of plate bars 24 to prevent twisting and warping of the horizontal bar 23 to support the aberration 20 without deformation.

A boosting unit 33 is mounted on the center axis 21 of the aberration 20 to increase the rotational speed of the generator 35 to increase the electromotive force to a large value (e = B1v sin ?, B: flux, l: : Speed, [theta]: angle between the coil side and the magnetic field), and the generator 35 can be downsized, so that electricity can be easily obtained. The bearing 30 is axially coupled to both sides of the central axis 21 of the aberration 20 to stably support the rotation of the aberration 20. The wing 22 of the aberration 20 is provided below the sea surface through which the water channel 10 flows and allows the aberration 20 to rotate by the sea water passing through the water channel 10. The wings 22 may be made in various shapes or shapes to increase surface contact of seawater.

It is also possible to provide an outer wall for protecting the aberration 20 from the wind pressure when the aberration 20 is installed.

In addition, the foundation structure 31 fixes and supports the bearing 30 at a predetermined height, thereby maintaining the aberration 20 at a constant height. Means may be added to the foundation structure 31 to raise or lower the aberration 20 as necessary so that the wings 22 of the aberration 20 are brought into contact with or not in contact with the sea surface. Further, the aberration 20 can be kept safe from flooding even if the sea surface is temporarily increased due to a typhoon or a tsunami by the foundation structure 31.

The generator 35 is axially coupled to the central axis 21 of the aberration 20 to convert rotational energy into electrical energy and output. The speed reducer 33 is axially coupled between the center shaft 21 of the aberration 20 and the generator 35 to increase the number of revolutions and includes a plurality of gears. The gear shifter 33 may induce a contact according to the gear ratio of the gears to increase or decrease the increase speed. The coupling 32 is axially coupled between the central axis 21 of the aberration 20 and the booster 33 and can separate the booster 33 and the generator 35 from the aberration 20. Further, the water gate 13 is installed at the inlet 11 or the outlet 12 of the water channel 10 to intercept the flow of the incoming seawater. The water gate 13 can facilitate the maintenance of the aberration 20.

5, when the separation structure 42 dividing the water channel 10 into plural pieces is provided, by providing the aberration 20 in each of the plurality of channels 10, Can be produced.

6, a plurality of inductive structures 40 and 41 are provided in a portion of the reef 1 that is in contact with the sea, in parallel with the flow of the algae to form a water channel 10 It will be possible to develop according to the bi-directional flow of algae.

The operation of the bidirectional algae generating system by the induction structure according to the present invention will be described.

4, when the aberration 20 is turned by the water passing through the water passage 10, the same amount of seawater is discharged from the wide inlet 11 to the narrow water passage 10 of the water passage 10, The flow of seawater in the water channel 10 is accelerated by the general formula of Q (sea water flow rate) = A (cross sectional area) V (flow velocity) The number of rotations of the aberration 20 is increased so that the depth of the seawater flowing through the narrow channel 10 when the seawater collects at the funnel-like inlet 11 of the channel 10 is deepened, (Water pressure) = γ (specific gravity) ㅧ z (depth) = ρ (density) ㅧ g (gravity acceleration) ㅧ z (depth) It will be done.

When the diameter of the aberration 20 is increased and the center axis 21 of the aberration 20 is increased, aberration due to aberration due to the expression of P (rotational force) = F (force) L (aberration diameter) The rotational force of the motor 20 is increased.

The bi-directional tidal power generation system using the induction structure is a power generation method that utilizes algae. However, it is an eco-friendly power generation method using only the tide difference between seawater. As a low-cost construction cost and easy operation of the facility, It is expected that it will be attracted to the sun and wind energy because it does not have natural damage and environmental pollution.

In addition, it is possible to maximize the rotational speed and the rotational force by the natural law by minimizing the width of the water channel relative to the flow rate so that a fast flow velocity is formed in the channel by the induction structure, and the narrow channel width can make the width of the aberration small. If the center axis of the aberration is made to be the maximum diameter, the large turning force can be obtained. By using the speed increasing unit on the central axis of the aberration, the rotational speed is increased to increase the electromotive force. This system has a merit of providing a very environmentally friendly bird power generation system that can obtain electricity by a low cost construction cost and simple facility operation by protecting the bearing by reducing the load of the aberration and smoothing the rotation of the aberration.

While the invention has been shown and described with respect to the specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. Anyone with it will know easily.
