Description

Large ships capable of wind power generation and carbon reduction

The present invention relates to a large ship capable of wind power generation and carbon reduction. It can protect a wind turbine rotating around a prop from strong winds and minimize energy consumption by using the wind to assist the ship's propulsion. It is about ships that can reduce carbon emissions.

As the demand for eco-friendly energy development increases, power generation using wind power generators is receiving attention worldwide. However, difficult environmental conditions are required to install a wind power generator.

For example, the location where the wind power generator is installed must be a place where wind speed above a certain level can be guaranteed to achieve meaningful rotation of the guide blades, and pollution due to noise generated when the wind power generator is running must not be an issue. It must be.

In addition, even if these environmental conditions are met, a very large area of space is required to install a wind power generator.

Depending on the direction of the rotation axis that drives the generator, these wind power generators are broadly classified into horizontal-axis wind power generators, which are installed horizontally, and vertical-axis wind power generators, which are installed vertically. Recently, wind power generators have been installed on ships to obtain eco-friendly energy and use it for power. Various efforts are being attempted to save energy.

However, wind power generators installed on ships act as a kind of drag, becoming an obstacle to the ship's progress, and have problems such as the risk of damage when faced with strong winds such as typhoons.

It consists of a lower support member 41 that supports the lower end of the cylindrical body 30b, and known rollers are formed on the inside of the upper support member 41a and the lower support member 41 to prevent friction with the cylindrical body 30b. It is configured to minimize. At this time, the upper support member 41a and the lower support member 41 include

hook parts

42, 42a spanning the upper and lower ends of the cylindrical body 30b, and the

hook parts

42, 42a are connected to the sail cover 40. ) consists of a coupling band (34, 43a) for coupling to.

The sail cover 40 is preferably configured to have an airfoil shape when viewed in cross section to improve air flow.

That is, when viewed in cross section, the sail cover 40 gradually increases in thickness from one end to the center, then gradually decreases in thickness from the center to the other side, and then increases again as it reaches the other end.

The sail cover driving means 50 includes a chain gear member 31 formed on the outer surface of the cylindrical body 30b, a rotation motor 51 installed on one side of the sail cover 40, and the rotation motor ( It consists of a drive sprocket 52 driven by 51) and meshed with the chain gear member 31.

It is installed on one side of the sail cover 40 and consists of a plurality of guiding blades 60 to guide the direction of the wind while covering the wind turbine 20. At this time, it is preferable that a plurality of the guidance blades (60) are installed in a row and are interlocked by the guidance blade rotation means (70) to open and close around each rotation axis (61).

It consists of a plurality of rotating sprockets (72) each installed, and a plurality of joint chains (73) connecting the rotating sprockets (72).

It is preferably composed of a connection frame 45 extending to one side from both upper and lower ends of the sail cover 40, and a rotation axis 61 of the guide blade 60 rotatably coupled to the connection frame 45.

In other words, the present invention provides for obtaining electrical energy by installing a known wind turbine (20) capable of generating power by wind power on the deck of a ship, and the wind turbine (20) is installed on a support (10) installed on the deck of the ship. Since it has a structure that rotates on a rotating axis, it is necessary to cover it to prevent damage when strong winds such as typhoons blow.

In addition, although the wind power generation turbine (20) generates power when the wind blows, it also functions as a kind of obstacle in the direction of movement of the ship, so it acts to reinforce the ship's propulsion by utilizing the already installed wind power turbine (20). It is clear that if done, it will be a ship with a very efficient structure.

In order to make this possible, the present invention includes a sail cover (40) to protect the wind turbine (20) from strong winds and to assist the propulsion of the ship by changing its position depending on the direction of the wind and acting as a sail. ) was created.

The wind turbine 20 includes a plurality of round-shaped turbine vanes 23 that are vertically installed between the edges of the circular turbine upper support plate 21 and the edge of the turbine lower support plate 22, and are fixedly installed at equal intervals, It consists of a support 10 that supports the center of the circular turbine upper support plate 21 and the turbine lower support plate 22. At this time, a generator (not shown) is installed at the top or bottom of the wind turbine 20, and the generated electricity is charged to a separate charging battery (not shown).

The sail cover 40, which is a very important element in the present invention, is preferably configured to cover part or all of the wind turbine 20 in order to protect the wind turbine 20 from strong winds.

In addition, the sail cover 40 has a structure that generates lift while rotating along the outer peripheral surface of the wind turbine 20 according to the direction of the wind in order to reinforce the propulsion force of the ship.

Lift means 'a force that occurs in a direction perpendicular to the movement when there is movement between a solid and a fluid.' Drag and lift forces act on all solids moving within a fluid. In other words, drag is the frictional force of the air that resists the direction of movement of the solid, and lift is the pressure at the convex upper part of the solid (sail cover in the present invention) placed in the flowing fluid, and the pressure at the concave lower part is greater. This pressure A force is applied in an upward direction due to the car, and lift is generated in the direction in which the force is received.

Therefore, in the present invention, the structure of the sail cover 40 has the shape of an airfoil, so that a lift force is generated in a direction perpendicular to the direction of wind, and ultimately the direction of the sail cover 40 is well adjusted. By generating lift in the sail cover 40, it is possible to have a separate propulsion force due to the wind in addition to the engine output of the ship.

As a result, it is clear that a significant amount of fossil energy can be saved by utilizing wind, an eco-friendly energy source, when operating ships.

Therefore, it is inevitable that the sail cover 40 has a structure that can rotate along the outer peripheral surface of the wind turbine 20.

The structure that makes this possible is the movable support members (41, 41a) and the sail cover driving means (50). That is, the position of the sail cover 40 can be changed in response to the direction of the wind by the

movable support members

41 and 41a and the sail cover driving means 50. At this time, the sail cover 40 may have a structure joined by

movable support members

41 and 41a.

The sail cover driving means 50 may be composed of a chain gear member 31 formed on the outer surface of the cylindrical body 30b, a rotation motor 51, and a driving sprocket 52, as described above. It is natural that it can be configured into a different structure using different driving means. In addition, as described above, a method of driving the drive sprocket 52 by directly meshing with the chain gear member 31 by the rotation motor 51 can also be used, but a gear is installed between the drive sprocket 52 and the chain gear member 31. A group 54 may be formed and the rotational force of the rotary motor 51 may be transmitted to the chain gear member 31 through the gear group 54. At this time, the gear group 54 is preferably formed as a bevel gear.

In addition, in order to facilitate rotation of the drive sprocket 52, the axis of the drive sprocket 52 is supported by a bearing, and the drive sprocket 52 is also supported by a mounting bracket formed on the sail cover 40. desirable.

In this way, the sail cover 40 is supported only by the

movable support members

41 and 41a, and when the sail cover driving means 50 is driven, the chain gear member 31 fixed to the cylindrical body 30b is also fixed. As a result, the sail cover 40 rotates around the wind turbine 20 along the outer surface of the cylindrical body 30b. At this time, the rotation amount and position of the sail cover 40 will be determined according to the direction of the wind, which controls the rotation motor 51 based on the sensor (not shown) for measuring the wind strength and direction and the information from the sensor. It will be determined by control means (not shown).

In addition, the present invention allows the wind turbine 20 to rotate by guiding the direction of the wind by forming a plurality of guiding blades 60 on one side of the sail cover 40, which means that the sail cover 40 provides lifting force. This is because it may interfere with the operation of the wind turbine 20 by blocking the wind when rotating to obtain .

In addition, the plurality of guide blades (60) block the wind in cases where the sail cover (40) alone cannot protect the wind turbine (20) from strong winds due to the small size of the sail cover (40). It is also possible to protect the wind turbine 20.

The guide blades (60) are installed on the connection frame (45) formed at the top and bottom of the sail cover (40), and the guide blades (60) are arranged in line with each other and interlocked by the guide blade rotation means (70). It is configured to open and close in the same direction at the same time by rotating it.

The induction blade rotation means 70 includes a drive motor 71 installed on the sail cover 40, a drive shaft of the drive motor 71, and a plurality of rotation axes installed on the plurality of guide blades 60. It is preferably composed of two rotating sprockets (72) and a plurality of joint chains (73) connecting the rotating sprockets (72).

That is, the rotational force of the drive shaft is transmitted to the rotation shaft 61 by the rotation sprocket 72 and the joint chain 73, so that the plurality of guide blades 60 are rotated and interlocked to open in the outward direction or the wind turbine. It is a structure that is interlocked and closed in the (20) direction.

In this way, the present invention allows to expand the protection area of the wind turbine 20 through the plurality of guidance blades 60, and also increases wind power generation efficiency by guiding the direction of the wind in the direction of the wind turbine 20 in case of emergency. It becomes possible.

As described above, although the present invention has been described in terms of limited embodiments, the present invention is not limited thereto, and the technical idea of the present invention will be described below by those skilled in the art to which the present invention pertains. Various modifications and variations are possible within the scope of equivalency of the patent claims.
