Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power-generating ship that utilizes both wave and wind energy, and aims to average the amount of power generated.

Conventionally, wave power generation has been proposed in which an air turbine is rotated by using the intake and exhaust of air by waves, and wind power generation has been proposed in which the wind turbine is directly rotated by wind power. However, energy in the natural world such as waves and wind power is not always at a uniform level and is highly uneven, in other words, it pulsates significantly, making it difficult to utilize. This creates a need to be able to work efficiently and withstand high energy levels. Therefore, it is necessary to increase the maximum capacity and maximum output of equipment such as generators, and even if high-output equipment is used, efficient power generation cannot be expected due to pulsation.

Therefore, in view of the above-mentioned drawbacks, the present invention maintains the pulsation of energy in the natural world to a certain level and averages it, making it possible to generate electricity efficiently using waves.
It was invented based on a novel idea for the purpose of providing a combined wind power generation ship.

In order to achieve this objective, the present invention divides the hull into a plurality of bottomless chambers using bulkheads, provides an intake valve and an exhaust valve on the ceiling of each of the plurality of chambers, and provides an intake valve that covers the intake valves of the plurality of chambers. An introduction chamber and an exhaust introduction chamber that covers the exhaust valves of the plurality of chambers are provided on the hull, and an air turbine outer cylinder having an opening in the exhaust introduction chamber is provided on the hull, while an air turbine outer cylinder having an opening in the exhaust introduction chamber is provided on the hull. A rotating wind cylinder is provided, and this wind cylinder is configured in two stages, upper and lower, with the leeward side narrowing in relation to the windward side air intake, and the above-mentioned turbine outer cylinder faces in the upper stage of the wind cylinder and is curved toward the air intake. The wind cylinder is characterized in that it is provided with a wind guide and communicates with the upper end of the wind cylinder, and that the lower part of the wind cylinder is provided with a wind guide at the intake port and has a bottom part that opens into the air intake introduction chamber.

Here, an embodiment of the present invention will be explained with reference to the drawings. FIG. 1 shows the overall structure of the power-generating ship of this embodiment. In Figure 1, a hull 1 of a power generation ship has a bulkhead 2.
A plurality of bottomless chambers 3 are provided along the longitudinal direction. And the ceiling part 3 of each room 3
A is provided with a pair of intake valves 4 and exhaust valves 5 for each chamber 3. The intake valve 4 has the role of letting air outside the chamber 3 into the chamber 3, and the exhaust valve 5 has the role of discharging the air inside the chamber 3 to the outside. Above the ceiling 3a of the chamber 3, on the hull 1, an intake introduction chamber 6 and an exhaust introduction chamber 7 are separated by a partition wall 8. The intake air introduction chamber 6 is formed to cover the intake valves 4 of all the chambers 3, and the exhaust air introduction chamber 7 is also formed to cover all the exhaust valves 5. An air turbine outer cylinder 9 is arranged at the upper center of the hull 1, and the upper end of this air turbine outer cylinder 9 is connected to an exhaust port 9a.
is present, and an air inlet 9b faces the exhaust gas introduction chamber 7 side of the air turbine outer cylinder 9.

A wind barrel 10 is provided on the hull 1 above the intake air introduction chamber 6 and the exhaust air introduction chamber 7. This wind barrel 10 has an air intake 10a and a main body 10b that is narrower than the air intake 10a, and is divided into two upper and lower stages. The lower stage has a wind guide 10c, the bottom part 10d is such that air flows into the intake introduction chamber 6 from around the air turbine outer cylinder 9, and the upper stage has a curved wind guide 10e, and the bottom part 10d has a curved wind guide 10e, and the bottom part 10d has a curved wind guide 10e. It is something that makes the wind swirl. The upper end of the wind barrel 10 has an opening, and this opening is equipped with a rectifying pipe 11. A wind regulating plate 11a is formed inside this wind regulating pipe 11 along the opening. Air intake 10a of wind barrel 10
There is a weather vane 12 on the opposite side. In addition,
10f in the wind barrel 10 is a wind collecting plate.

Next, a more detailed explanation will be given with reference to FIG. 1 and other figures. The wind barrel 10 can be rotated by itself by means of a weather vane 12 so that the intake port 10a always faces upwind, and wind blows into the intake port 10a facing upwind, as shown in FIG. Air intake 10a
The wind entering the wind barrel 10 from above becomes a left-handed swirling flow because the wind guide 10e at the upper stage of the wind barrel 10 is curved as shown in Figure 4a, and the wind barrel 10 is narrowed. Therefore, the turning speed becomes faster.
In addition, the wind entering the lower stage of the wind barrel 10 is also controlled by the wind guide 10c.
The speed increases as it is guided and narrowed. and a bottom portion 10 through which the air turbine outer cylinder 9 passes.
Wind enters the intake introduction chamber 6 through the opening d.

On the other hand, when waves arrive in the bottomless chamber 3, the volume of the chamber 3 shown in FIG. 3 decreases due to the rise of the water surface. As a result, the air that entered through the intake valve 4 when the water surface was lowered is blown out through the exhaust valve 5 and directed toward the air inlet 9b of the air turbine outer cylinder 9. Also,
Regardless of the size of the wave, it enters the lower stage of the wind cylinder 10,
The wind that has entered the intake air introduction chamber 6 opens the intake valve 4 and enters the chamber 3, and at the same time opens the exhaust valve 5 and heads toward the air inlet 9b. All the air blown out from the exhaust valve 5 is blown into the air inlet 9b to rotate the air turbine 13 provided near the exhaust port 9a of the air turbine outer cylinder 9. The air turbine 13 is supported on a bearing arrangement 14 which supports a shaft 15 . 16 is a guide vane which also serves as a support for the bearing device 14. The shaft 15 extends into the chamber 3,
A flywheel 17 and a generator 18 for energy storage are attached to the lower part of the chamber 3.
The shaft 15, flywheel 17, and generator 18 are watertightly protected by a protective tube 19.

The airflow coming out of the exhaust port 9a of the air turbine outer cylinder 9 rises, but the air that enters the upper stage of the wind cylinder 10 and swirls around sucks out the airflow from the exhaust port 9a. That is, as shown in FIG. 4a, inside the wind barrel 10, the airflow is narrowed to the cylindrical radius R, so the wind speed is high, and the height is considerably higher than the width, and the upper part of the wind barrel 10 is When it reaches the top, more wind is blown into the swirling upward wind from the bottom, resulting in even higher speeds. When this speed exceeds a certain level, a boundary layer is formed and a columnar layer with extremely low air pressure is formed at the center of the swirl. This artificial tornado then powerfully sucks out the airflow from the exhaust port 9a. This powerful suction is carried out by air turbine 1
3, greatly increase the rotation speed.

If the swirling rising wind is released outside as it is, there is a risk that it will grow into a natural tornado in strong winds, and the noise will also increase, so a fan-shaped wind rectifier 11 as shown in FIG. 4b is installed in the upper opening of the wind barrel 10. A large and small baffle plate 11a in the baffle tube 11 stops the swirling flow, rectifies the flow, and discharges the airflow to the outside.

Figures 5a and 5b show the exhaust valve 5 and intake valve 4 caused by waves.
This shows the movement. In this figure, the tip and rear ends of the hull 1 are floating chambers. Although this embodiment targets a ship floating on water, it may also be installed on a quay.

The size and pitch of waves usually change, and the amount of energy they hold is also uneven. Therefore, it is conceivable to arrange the power-generating ships at certain pitches in the direction of the waves to alleviate the above-mentioned unevenness. On the other hand, the way the wind blows is also highly uneven, but in this embodiment, such unevenness can be made uniform.

As explained above in the embodiments, according to the present invention, the hull is divided into a plurality of bottomless chambers by bulkheads, and an intake valve and an exhaust valve are provided on the ceiling of each of the plurality of chambers. An intake introduction chamber that covers the intake valve and an exhaust introduction chamber that covers the exhaust valves of the plurality of chambers are provided on the hull, and the bottom of a wind barrel having an air intake provided on the hull opens into the intake introduction chamber. On the other hand, an air turbine outer cylinder having an opening in the exhaust introduction chamber is provided on the hull, and an air turbine for power generation is provided inside this air turbine outer cylinder, so that pulsation caused by wind or waves is absorbed by both energy sources. The blowing process averages out the energy, and there is less chance that the energy from waves and wind will reach their maximum at the same time, making it possible to reduce the maximum capacity of equipment such as generators, making it possible to generate electricity with high efficiency.
