2. Commercialization of practical offshore power generation system to maximize efficiency

3. Construction of offshore power generation system that is easy to install, assemble, disassemble and maintain

1. The present invention can commercialize marine power generation by applying 'Method to maximize the conversion efficiency of algae energy to wind power energy', which is the inventor's registration technology (registration number 2004585270000, registered date 2012.2.2, patent holder: Byung-woo Jung). I would like to suggest a solution.

2. The present invention is designed to install windmill-type wind power generators on the barge floated on the sea where useful algae are formed, such as [representative map], to promote wind power generation using wind blowing over the sea, and flows below the barge (in the sea). Install the injection pump pipe body (block) connected in parallel in the tidal current, and combine the air induction pipe connected to the injection pump pipe through the barge from the barge and pass through the injection pump pipe. Due to the hydrodynamic characteristics, the air flow is generated below sea level in the air induction pipe by using the low pressure relatively lower than the atmospheric pressure induced at the joint portion of the injection pump and the air induction pipe. Install an algae generator as an energy source to drive fans, turbines, etc.) Use the flow and to build a more practical maritime development schemes.

3. For this purpose, a parallel-coupled offshore power generation system that generates electricity by collecting electricity produced from each independent power generation unit using wind energy and tidal current energy, as described in the previous paragraph [2]. To solve the problem.

4. In addition, combine the large gear to the rotary shaft of the windmill installed on the barge, and combine the small gear connected to the rotary shaft of the rotor (007, fan or turbine, etc.) in the air induction pipe formed into the barge, and then connected by chain It is designed to drive the large generator (008) with high generation efficiency by utilizing the large rotational torque of the windmill. 1] to solve the problems of the present invention.

5. Finally, the rotational force of the windmill 001 is connected to the main generator 008 using the chain gear system (019, 020, 021, 022) in order to operate a large generator [Fig. 1, 008] that requires a large torque during initial driving. When the generator starts to operate, the main system is promoted by intermittent connection between the windmill and the main generator through the clutch system (023), and the surplus rotational force of the windmill is separated into the generator [Fig. 2, 004]. By allowing the secondary power generation through the power generation, the offshore power generation apparatus that combines the respective power generators in a series-parallel mixed mode to enable the maximum efficiency of the power generation from each power generator using the wind energy and tidal stream energy [Fig. 2] It is proposed to solve the problem of the design.

Based on the prior art registered by the present applicant to implement the marine power generation apparatus according to the present invention, the following virtual apparatus similar to the [representative diagram] is designed, and the expected power value obtained from the apparatus is a valid expected value. By demonstrating that the present invention is a concrete and feasible design.

The marine power generation apparatus of the present invention, such as [representative diagram], will be installed in a sea where wind speeds of 10m / sec are blowing. In addition, in order to enable effective offshore power generation, an embodiment of the present invention is provided with a windmill having a diameter of 3m to promote wind power generation, and each inlet diameter is 3m and nozzle diameter in a tidal current (flow rate of 3m / sec) of about 5m depth below the barge. After four parallel injection pump pipes of 0.6m are connected, the air flowing through the air induction pipe (diameter 1m) connected to the injection pump pipe from the water surface passes through the rotor (fan or turbine, diameter 1m). When designing a device that flows into seawater through four injection pump pipe nozzles with a diameter of 0.2 m, it is distributed in the direction of seawater through the injection pipe. Calculate the effective work rate (power generation, power value) that can be expected through the marine power generation device of the present invention. (However, the flow rate of the air inlet part 002 is the same as the wind speed of the sea wind (10m / sec). Based on the inlet wind speed 0 m / sec) And to calculate the minimum tide generation.]

From the above-described calculations derived by the prior art registered by the applicant, one day [kinetic energy (Power, P) of the fluid per unit time is the density ρ flowing through the canal of the cross-sectional area A (radius r) at a speed of v Since the kinetic energy (½mv ² ) of phosphorus fluids (air, water and algae, etc.) means one work per unit time, the power value is

(Power) = ½ (dm / dt) v ² (1)

Since the microfluid with a moving speed of v moves the microdistance Δl = vΔt during the micro time of Δt, the mass component of the microfluid (the fluid having the density ρ), Δm = ρAΔl Because of

           Δm = ρAvΔt or Δm / Δt = ρAv (2)

That is, it can be seen that the mass flux, which means the mass of the fluid passing through any cross-sectional area per unit time, does not change with time when the fluid is in a normal flow.

Therefore, from the formulas (1) and (2), the effective factor value which means the amount of wind power generation can be obtained as follows.

(Power) = ½ρAv ³ = ½ρ (πr ² ) v ³ (3)

In other words, the power value (power) of the power generation equipment is the power generation amount of the wind power generator in which the power rate (power) is proportional to the cube of the flow rate (wind speed).

 In addition, according to the prior art registered by the Applicant, the formula derived for calculating the flow velocity in the air induction pipe through the energy conservation law is rearranged using the relation between work and pressure summarized in [Theorem of Code] as follows. .

½ρ '(πr ₃ ² ) v ₃ ³ = n × [½ρ (πr ₁ ² ) v ₁ ³ ]

-[(ρ'πr ₃ ² v ₃ ) × g]? h-P ₁ ? [π (r ₄ ) ² × v ₃ ] (4)

Therefore, the fluid induced in the air induction pipe from Equation (4) to obtain the expected power amount that can be generated by converting tidal current energy into wind energy with the offshore power generation unit combined in parallel like the virtual device presented above by the present invention. If you calculate the air velocity (v ₃ ) first,

½ (1.225 kg / m ³ ) [3.14 × (0.5m) ² ] × v ₃ ³

= 4 × {½ (1,030kg / m ³ ) [3.14 × (1.5m) ² ] (3m / sec) ³ }

-[(1.225kg / m ³ ) [3.14 × (0.5m) ² ] × v ₃ × (9.8m / sec ² ) × (5m)

(1.5) × (1,013) × (100) [(kg? M / sec ² )] / (m) ² × [3.14 × (0.1m) ² ] × v ₃

from

v ₃ ³ + 10,038v ₃ 818,657 = 0

We can find a cubic equation with v ₃ as a parameter: If we find the value of v ₃ from the root of the cubic equation (x ³ + px + q = 0),

v ₃ ≒ 60 m / sec (5)

Substituting this value into Equation (3), it can be seen that the amount of power generated from the tidal current generator according to the present invention is about 103,856 (Watt). In addition, it can be seen that the amount of wind power that can be obtained from one windmill having a diameter of 3 m lying within 10 m / sec of wind speed is about 4,327 (Watt) based on Equation (3).

Therefore, according to the present invention, which is constructed in parallel as shown in the [Representative diagram], it is expected that the total of the expected electric power that can be generated from each of the wind and algae generators from the wind and the sea tides is about 108 KW. It becomes possible.

That is, the objective of the present invention can be realized through the marine power generation device of the present invention, and the theoretical result value that is the background for the commercialization can be leaked.

In addition, the chain gear is attached to the rotating shaft of the wind and tidal current generators, such as [FIG. 1] and [FIG. 2], which is different from the above virtual apparatus that combines the wind power generator and the tidal current generator in a parallel manner as shown in FIG. Rotors (fans or turbines) installed in the air induction pipe, which can be connected and interrupted through the clutch system by coupling the chain energy of the windmills having a large torque by combining them in series and series-parallel mixing using a chain. Wind power generation using the excess rotational energy of the windmill in the offshore power generator [Fig. 1] and [Fig. 1] designed to drive a large generator requiring a large drive torque connected to the rotating shaft of the The offshore power generation device designed to produce additional electricity by installing a separate generator (004) [Fig. 2] In addition, the expected power amount that can be generated by the tidal current generator alone from the above result It is expected to have a result value close to or above (104 KW).

Therefore, the offshore power generation device of the present invention combining the wind power generation device and the algae power generation device in a parallel, series, and series-parallel mixed manner as in the above specific example, compared to the single generation using only the algae generation device, which is the applicant's registered technology. 1, 2] can produce more efficient electricity.

It is thought that this design will be an alternative to realize the offshore marine development using the viable algae which is scattered abundantly on the south coast and west coast of Korea.

In addition, Uldolmok Helical Algae Power Generation (2003 ~ 2009), Yeosu Myodo HAT Floating Algae Power Generation (2006 ~ 2008), Hadong Waterway Helical Algae Power Generation (2006) It is hoped that this design can provide a new opportunity for reviving most of the algae plans that have been discontinued and discarded during review, planning or development in Korea and commercializing marine power generation.

Through this, we can commercialize tide and sea breeze, one of the marine resources on the three sides of the sea into offshore power generation like this design, so that Korea, which is a resource-deficient country, will be able to cope more actively with the energy problem that we will face in the near future. Hope.
