Description

  The present invention takes seawater from the sea, creates a flow of seawater by developing waterways and flow pipes, and uses that water flow to generate electricity with a coma-type water turbine. The present invention relates to generating electricity without carrying out carbon dioxide.

As a power generation method using water, power generation is performed by hydroelectric power generation by a large dam type or small hydropower generation as a small-scale power generation.
Regarding the use of ocean energy, experiments and research on power generation using tidal currents and ocean currents have been conducted and implemented.
Large-scale power generation is performed by dam-type power generation, but on the other hand, small hydropower generation using a water turbine is small in scale and generates a relatively small amount of power.
It has not been established how to take seawater, which is considered to be ocean energy, install a water channel, develop a water pipe, and use it for power generation.
For this reason, a power generation top type water turbine for generating power by absorbing water flow more stably is provided and power generation is performed using seawater.

Research on practical application of tidal current power generation equipment Japan Coastal Security Research Center

As for the use of ocean energy, experiments and research on power generation using tidal currents and ocean currents, and ocean temperature difference power generation are being conducted in the region.
In hydroelectric power generation, in order to generate power at many power plants, power generation is generally performed by a turbine generator that generates power using a power generation turbine.
However, in terms of power generation, power generation by small hydropower generation is less than that by hydropower generation. The sea is like an endless dam lake, and in order to generate power using seawater, it is possible to establish a stable power generation method by using what means and methods to establish a stable water flow Is the problem.

  In order to generate power using seawater, etc., in order to clarify the method of sustainable power generation and improve efficiency, we will clarify methods that can reduce power generation costs and establish new methods for power generation. The challenge is how to achieve this.

Sea water and river water can be said to be the best power generation energy that can be used for power generation without emitting carbon dioxide. In particular, ocean energy, which is ocean energy, exists indefinitely, and is considered to be the easiest to use for power generation.
Seawater is stable in terms of the amount of water, and is a method of generating power by using the flow of seawater or the like using a power generation top type water turbine or the like that is easily subjected to water flow. Adjust the water depth, water channel, flow pipe, etc. to create a water flow, and prevent debris from entering the sea water etc. in the water flow pipe, and devise to increase the flow speed of sea water flowing in the flow pipe, If a large number of Koma type turbines are installed and many power generation facilities are established, stable power generation and reduction of power generation costs can be achieved.
This will lead to the reuse of seawater that was previously unused.

As an effect of the invention, if it is possible to generate electricity using a coma-type turbine for power generation that is more susceptible to water flow, which is different from the turbines that have been used so far, the utilization of unutilized energy such as seawater can be achieved. In terms of the environment, carbon dioxide is not emitted and permanent power generation is possible.
Seawater in the ocean exists infinitely and is stable, so power generation using a Koma type water turbine will greatly increase the amount of power generation and contribute to global warming countermeasures. If a large number of power generation facilities are installed and power generation is possible, the effect will be great.
And the effect of enabling the price reduction of electric power generation by increasing electric power generation amount and suppressing electric power generation cost can also be expected.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1, 2, 3, and 4.

The generation of power using seawater and the like is sufficiently possible to use for power generation because seawater is quantitatively stable with reference to hydropower and small hydropower.
In the case of using seawater, in the plan view of the power generation facility using seawater (Fig. 1), the seawater is taken from the seawater through the 1 water intake through the 2 water intake pipes into the 3 flow rate adjustment tanks for stabilizing the seawater flow velocity. As shown in the cross-sectional view of the power generation facility using seawater (Fig. 2), a flow of seawater is created at an inclination from the 3 flow rate adjustment tanks to the 9 power generation facilities, and the plan view of the power generation top type turbine (Fig. 3) ) And a cross-sectional view of the power generation top type water turbine (FIG. 4), it is intended to be used for power generation by rotating a 10 power generation top type water turbine.

In order to create a stable water flow, in the power generation facility using seawater, the water flow is adjusted by taking the seawater from the 2 intake pipes into the 3 flow rate adjustment tank and adjusting the amount of water flowing from the 3 flow adjustment tank to the 4 channels and 5 flow pipes. Stabilize the four water channels with slopes and steps (enlarged view in Fig. 2-1), and create a water flow at the speed necessary for power generation by making efforts to increase the flow velocity.
In addition, taking a large amount of seawater and using it for power generation requires draining a large amount of seawater at the same time. 7 drainage gutters will be installed next to the power generation facility to drain the seawater overflowing from the 4 waterways.

In order to increase the power generation capacity of the water turbine used for power generation, as shown in the plan view of the power generation top type water turbine (FIG. 3) and the cross section of the power generation top type water turbine (FIG. 4), the water turbine has more water flow. Therefore, it is necessary to increase the rotational force of the main body of the turbine and the rotational force of the rotating shaft of the turbine.
A coma-type water turbine for power generation is aimed at satisfying such requirements, and this 10-power coma water turbine is installed and used for power generation.
As shown in the plan view of the power generation top type water turbine (FIG. 3) and the cross section of the power generation top type water turbine (FIG. 4), the characteristics of the power generation top type water turbine are as follows. The blades of the 11-frame type water wheel are also installed on the outside and inside of the water wheel so that the two-stage blades receive the water flow and receive the water flow up to the blades outside the tip. The rotation speed of the water wheel is increased by the large, medium and small gears installed inside the water wheel, and the rotation speed of the gear is increased and transmitted to the 12-rotation conduction shaft.
In addition, the installation portion of the gear inside the water turbine is partitioned by a wall so that seawater does not enter from the outside.
As for the rotation of the gears installed in the water wheel, as shown in the sectional view of the power generation top type water wheel (FIG. 4), the 14 large gears and the 15 middle gears mesh with each other in the clockwise direction, The 16 small gear is meshed with the 16 small gear and the 12 rotating transmission shafts and rotated counterclockwise.
The rotational force is transmitted to the 12-rotation conduction axis. Further, the rotational force of the 12-rotation transmission shaft inside the 13-rotation transmission shaft protection tube is not lowered, the rotational force is transmitted to the 8 generators installed in the 9 power generation facilities, and the 8 generators are operated to generate power. Is to do.
Also, regarding the number of gears installed inside the Koma type turbine, depending on the size of the Koma type turbine, many gears can be installed, or the two stages of blades of the Koma type turbine can be set in three stages to achieve a rotational force. Devise to increase
In order to support the top type water turbine, as shown in (enlarged view of FIG. 1-1), the 10 power generation top type water turbine is supported by 18 struts on both sides with a 13-rotation conduction shaft protection tube. Further, in order to increase the flow speed, a step is provided in the four water channels so that the water flow falls on the blades of the 11-frame type water turbine so that the blades can be easily rotated. As shown in FIG. 2A, the portion where the 10 power generation top type turbine and the seawater are in contact with each other is the blade portion of the 11 top type turbine, which is the lower part of the 13-rotation conduction shaft protective tube. This is because the blades under water and the blades outside the seawater work together to maintain a stable rotational force.
In this way, the top type water wheel is to increase the rotational force of the water wheel by providing two stages of blades that receive the water flow, and to increase the rotational speed by installing a gear in the water wheel. And the 14 large gears, the 15 middle gears, and the 16 small gears inside the water turbine are connected to and connected to the 12 rotation transmission shaft, and the 12 rotation transmission shaft is installed inside the 13 rotation transmission shaft protective tube. It is a mechanism to transmit the rotation to 8 generators in 9 power generation facilities.
The Koma type turbine is designed to be used even in places where the head of the water flow is small, and the Koma type turbine has a stronger rotational force than the normal turbine in that it is used for power generation to increase the rotational force. Is something that can be done.
In this way, power generation using the top water turbine that uses seawater can be performed using river water, and power generation using the top water turbine increases the amount of power generation, enabling permanent and stable power generation. Is.

  In the construction of power generation facilities, the construction cost can be reduced compared to dam construction, and it is difficult to find the location in the mountainous area, etc. for the dam construction, but using seawater and water The location and construction location of the power generation facility for generating power using the Koma type water turbine can be obtained relatively easily even in the construction of the power generation facility such as the area close to the coast or the river side relatively close to the flat ground. For example, power generation facilities using power generation top-type turbines can be installed on both sides of the waterway, and power generation costs can be reduced and the amount of power generated can be increased by generating power generation facilities.

In power generation, it is relatively easy to take seawater and water from the sea or river and use it for power generation. Can be reduced.
Also, in terms of power transmission, unlike hydroelectric power generation facilities such as dams, power transmission facilities can be installed not on mountainous areas but on relatively flat plains or points close to the coast.
In this way, the use of seawater for power generation reduces the location of the power generation facility and the construction cost, and also leads to a concrete clarification of stable and permanent power generation. It is possible to expand the industrial use by promoting the lowering of prices.
