Abstract

PROBLEM TO BE SOLVED: To enable power generating work to be carried out without depending on nuclear power generation or fossil fuel by eliminating some defects found in the present situation that an ocean stream at sea and a tidal current appeared in a low tide and a high tide form a torrent or a rapid flow with huge energy depending on a place, and, in addition, that such huge energy as that from a rapid flow in a river, in particular a large-sized river, is always casually casted aside at present, which might not be utilized unless large-scale work such as dam construction is performed.SOLUTION: A floating type power generating device of the present invention catches huge energy to enable electricity to be generated almost merely throwing an apparatus in such a field of huge energy, and is a huge capacity power generator device floating at sea having cylindrical sealed rotary bodies surrounded by several tens of rows of blades 100 m long. Its specific feature is the fact that three types of water collecting devices are arranged in front of the rotary bodies to add a capability of collecting huge energy.

Description

The present invention relates to a hydroelectric generator capable of generating electricity only by being installed (installed or floated) in the sea or river.

In the case of rivers, large-scale hydroelectric power generation was impossible unless large works such as dams were used.
In addition, power generation using ocean currents is very small, and the propeller-type small to medium-sized models are moving a little, and no technology has been established to capture large amounts of energy from the ocean currents and generate large-capacity power.

The drag type of the present invention is not found.

The problems to be solved are: (1) Capturing enormous energy from tidal currents generated by ocean currents and low tides, enabling large-capacity power generation.
(2) Regardless of dam construction, the energy of the river water flow is accompanied by small construction such as installation, but we have developed a device that can generate a large power generation capacity just by throwing in the device. To change the current situation that has been thrown away, so that the huge energy of rivers can be utilized.

By making a cylindrical water turbine that has a large number of hydraulic power capture containers (wings) on its surface to capture the energy of the water flow and rotate it using its drag, and make a device that collects and directs the hydraulic power in front of this water turbine , Get the rotational force with the energy of the water flow.
In a stream flowing in one direction of a river or ocean current, a large rotational force cannot be obtained unless the large negative effect received from the stream is reduced when the wing moves to the side that must advance against the stream.
Therefore, as shown in (Fig. 2-1), the negative effect is reversed by making a water collecting directing device (represented as P in the figure) that changes the flow on the side that originally produces only a negative effect. Switch to. In addition, although it is not usually possible to obtain a rotational force from the downstream part of the flow (lower half of the cylindrical rotating body in the figure), it is also possible to assist the rotation from the downstream by providing a water collecting directing device (expressed as Q in the figure). To get a water flow that
Next, Fig. 2-2 shows a phase-directed water collection directing device when the water flow direction is reversed at low tide and high tide.
This is less efficient than the unidirectional water collection directing device (Fig. 2-1), but it is not necessary to change the direction of the entire device depending on the direction of the flow, so computer control is unnecessary, and there are fewer failures accordingly. I can do it.
Next, an omnidirectional water collection directing device in the case where the direction of the water flow is not fixed, accompanied by a vortex and a turbulent flow, is shown in FIG. This is a curved water collection directing device made with the idea of P in (Fig. 2-1), greatly reducing the negative flow effect compared to conventional linear omnidirectional water collecting and charging devices. However, by producing a little positive effect, it produces a rotational force superior to a linear water collecting device. As shown in (Fig.2-3), the linear water collecting device produces almost only the effect of shielding the negative flow, but it is similar to P in (Fig.2-1) by making it curved. Work. (Figure 2-3) is a comparison of one direction of the water flow, but since the water collecting device of 360 degrees and the same shape is provided, the same effect can be obtained regardless of the direction of the water flow. .
In addition, this cylindrical rotating body hydroelectric generator with a curved water collection directing device is "simple mass-production type that generates electricity without worrying about the direction by simply throwing it into the water flow in a river or sea with a high flow velocity (just installing or floating). Is also effective.
Next, the features and precautions of this device.
(1) Large-capacity power generation is possible because the wings can be enlarged by the depth of the river or sea. However, the river is assumed to be flooded. (I) A trash fence will be installed. (Ii) The wing and the cylindrical rotating body should be made several meters higher than the normal water surface when flooding. (Iii) The capacity of the generator (Iv) The nacelle is installed further upwards in response to the water increase, and is shot with buildings or shores and ropes to prevent runoff.
(2) In the case of the sea, the tidal current is often about 150m, so the wing length should be up to about 100m.
(3) Because it is a drag type, it is necessary to increase the ratio of the opening and outlet of the water collecting device and increase the flow velocity. However, since the high-speed rotation speed cannot be obtained, the speed increasing device is diverse and the torque is strong. High speed rotation is obtained by taking advantage of this feature.
(4) Since the nacelle is above the water surface, there are few failures due to corroded water.
(5) It is necessary to make the water collection directing device large at a flow rate of 1 m / s to 2.5 m / s to maximize the effect. To avoid spills and collapses. Also, pay attention to the design so that the water passage is sufficiently wide.
(6) The floating type lowers the squid in more than 4 directions to prevent the entire device from rotating.
Shoot at the shore and rope in a torrent like a fjord.

The hydroelectric power generation device of the present invention uses a natural river, ocean current, tidal current without any major construction such as a dam, and provides a device with a function of directing water collection in front of the turbine. This means that power generation is possible. In the present invention, both the installation type floating body type generates electric power semi-automatically by simply throwing it in, and it is possible to easily utilize the enormous energy on the earth that has been thrown away until now.
There is also an effect of the invention that the power generation cost can be greatly reduced. The type that floats on the sea has more than a dozen rows of 100m wings, suitable for capturing the enormous energy of ocean currents, and has the effect of making it possible to generate enormous power with natural energy without relying on nuclear power.

Japan's Bungo Channel reaches 3m / s, creating a vast tidal current. In addition, on the north side of Nakatsurijima, the Goto Islands, there is a wide flow of 24-hour ocean currents, and Japan is an island country, and there are such enormous energy fields throughout the country.
Even if you look around the world, there are countless enormous energy fields such as the Yangtze River, the Lena River, the Yukon River, the Amazon River, etc. that have abundant locations with abundant water.
Until now, these enormous energy fields have been neglected because there was no device that could capture enormous energy, and no device that could handle enormous energy. Also shows that power generation is possible.
Therefore, it is considered to be appropriate to verify and implement at the national level because it is greatly related to the national interest.

In a small valley river, in a fast flow of about 1.5m / sec between the rocks, four vertical hydraulic capture containers made of plastic containers in a cylindrical rotating body as shown in a row. When an experiment was conducted using a water turbine having 8 rows, sufficient torque was obtained.

Since power generation costs are cheap, mass production of equipment is performed.
In addition, there is a problem of power transmission due to the large amount of power generation in the ocean currents of the remote islands and the rivers in the wilderness, but without transmitting power, the water is electrolyzed locally using cheap power ( Mass production of (H ₂ + CO ₂ → HCOOH) (formic acid liquid), and the industry that uses it for fuel cells and electric vehicles will be in full swing.
