Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sailing device that is installed on marine equipment and sails the equipment using wind power.

In recent years, various plant barges for seawater desalination, power generation, valve manufacturing, etc. have been put into practical use, and after being built at bases, they must be towed over long distances to their installation locations. These barges have large towing resistance because there is little consideration given to various types of resistance in terms of equipment placement and overall construction costs, and therefore the tugboats that tow them are large. It also requires a huge amount of fuel for towing.

Furthermore, other types of marine equipment that need to be towed over long distances include oil drilling rigs such as the jack-up type. In this case, in addition to moving from the construction site to the first drilling site, it is often necessary to tow the vessel to a different location, such as from Indonesia to the waters near Japan.
This is exactly the same situation in the case of self-lifting offshore platforms.

Therefore, in order to save fuel on tugboats, attempts have been made to stretch sailcloth between the columns of a jack-up type rig and tow it in waters with a relatively steady wind direction, but this method does not require any control device on the sailing device. Because the system was not equipped with a system, it was not very effective, and new problems arose, such as difficulty in maneuvering the ship, and it was not put into practical use.

On the other hand, sailing vessels developed for oil tankers and bulk carriers are characterized by mechanical and automatic control of the sailing equipment, which saves labor and improves efficiency while saving engine fuel. For ships of this type that operate on a regular basis, even when equipped with such advanced equipment, the investment can be fully recovered. However, applying this to items that are rarely towed, such as the above-mentioned marine equipment, is extremely disadvantageous in terms of investment recovery.

The present invention has been made in view of the above points, and is capable of providing a rotating body with wings and a wind receiving body, and using it as a wind power generation device to supplement electricity when at anchor, and as a highly controllable sailing device when being towed. The present invention provides a sailing device for marine equipment that improves operating efficiency and facilitates recovery of initial investment.

Hereinafter, its configuration and the like will be explained in detail with reference to embodiments shown in the drawings.

This embodiment shows an example in which the present invention is implemented on a plant barge, in which Fig. 1 is a front view of the sailing device, Fig. 2 is a sectional view along AA of Fig. 1, and Fig. 3 is a longitudinal sectional view of the sail extension mechanism. FIG. 4 is a side view, and FIG. 5 is a block diagram. In the figure, on the plant barge,
An electric motor/generator 1 for both electric and power generation is connected to an inboard power supply, and a transmission 3 is directly connected to a rotating shaft 2 of the motor/generator 1. Furthermore, an electromagnetic brake 4 is attached to the rotating shaft 2 to brake its rotation. On the other hand, near the electric generator/generator 1, a rotating shaft 7 that is rotatably supported by upper and lower bearings 5 and 6 is installed upright.
and the output/input shaft 8 of the transmission 3 are drivingly connected by bevel gears 9, 10 and gears 11, 12. Further, a clutch 13 is provided between both shafts 7 and 8 to connect and disconnect rotation transmission between the two shafts.
Further, a flywheel 14 is attached to the lower end of the rotating shaft 7 to provide rotational inertia thereto.

At the upper end of the rotating shaft 7 and at the lower end near the bearing 5, four pairs of upper and lower horizontal support members 15 and 16 formed in a hollow shape are arranged at the same positions above and below at points that divide the entire circumference into four equal parts. It protrudes in the radial direction,
The mounting portion is reinforced with reinforcing material 17. and,
The rotating shaft 7 and the supporting members 15 and 16 form an integral rotating body 18. Further, the four tips of the upper and lower support members 15 and 16 are vertically connected by blades 19 having a streamlined wing-like cross section as shown in FIG. By being received by the rotating body 18, the rotating body 18 is rotated integrally with the rotating body 18. Also,
The support members 15 and 16 have a hollow triangular cross-sectional shape in order to increase the rotational force when the rotating body 18 rotates and to improve the rigidity. That is, as shown in FIG. 3, the surfaces 15a and 16a of the support members 15 and 16 that receive wind pressure
is a vertical surface 15 that does not contribute to rotational force.
b, 16b are formed in a streamlined shape, and there is a difference in the resistance of both surfaces.

A sail 20 as a wind receiving body is provided in a space surrounded by a pair of wings 19 that face each other on a straight line among the four wings 19 and the upper and lower support members 15 and 16 so that it can be freely expanded and stored. It is being That is, inside the upper support member 15, a winding drum 21 rotated by a winding mechanism (not shown) is supported over its entire length, and a thin groove 22 is formed in the center of the lower surface of the support member 15. are provided along the entire length. Further, a curtain rail type guide rail 23 is attached to the rotating shaft and the blade 19 in correspondence with the narrow groove 22. One end of the sail 20 has a narrow groove 2.
A large number of metal fittings 24, which are inserted from 2 and fixed to the winding drum 21 and attached to both side edges of the sail 20, are slidably engaged with the guide rail 23. By doing this, the winding drum 2
By rotating the sail 20 in the forward direction, the sail 20 is stored in the support member 15, and by rotating it in the opposite direction, the sail 20 is expanded by its own weight while being guided by the guide rail 23. Note that the lower support member 16
is provided with a metal fitting (not shown) that fixes the lower end of the sail 20 when it is extended.

Sailing devices 25 configured in this manner are provided in two sets at the front and rear of the barge, and each electric motor/generator 1 is connected to a storage battery 26 and a generator 28 directly connected to a diesel engine 27. At the same time, it is connected to a load 29 installed inside the barge.

The operation of the sailing device 25 configured as above will be explained. First, when a plant barge equipped with the sailing device 25 is anchored in a port or the like, the winding drum 21 is rotated to store the sail 20 in the horizontal member 15. When the blade 19 receives wind pressure, the rotating body 18 rotates, and when the clutch 13 is connected, the rotation of the rotating body 18 is transmitted to the electric motor/generator 1 via the gears 11, 12, bevel gears 9, 10, and the transmission. be done. Therefore, power is generated and this power is supplied to each load 29 and storage battery 26 inside the ship.

Further, when the plant barge is towed by a tugboat and headed for the installation location, the winding drum 21 is rewound and the sail 20 is expanded. Then, when the electric power from the storage battery 26 or the generator 28 is supplied to the electric motor/generator 1, this turns into an electric motor, rotates, and is transmitted to the rotating body 18 through a path opposite to that described above. In this case, the transmission 3 becomes a speed reducer, and the rotating body 18 rotates at a low speed. Then, when the rotating body 18 is rotated to the desired position according to the wind direction and the power is turned off, the rotating body 18 stops and the electromagnetic brake 4 is activated, so the rotation of the rotating body 18 is braked and fixed at the desired position. Ru. After doing this, when the plant barge is towed, the sail 20 receives wind pressure and the plant barge sails. When the wind direction changes during navigation, the direction of the sail 20 can be easily controlled by rotating the electric motor/generator 1, making maneuvering of the vessel easy.

FIG. 6 is a front view of main parts showing another embodiment of the present invention, and FIG. 7 is a BB sectional view of FIG.
A plurality of wings 30 are used instead of zero. That is, the upper and lower support members 15 and 16 are connected by a plurality of blades 30 formed in approximately the same shape as the blade 19 of the above embodiment, and these blades 30 can adjust the area of the wind received. It is formed so that it can rotate freely. The rest is the same as the previous embodiment.

In the sailing device 31 configured in this way, the wings 30 are attached to the support member 16 as shown in FIG.
By rotating the blades in a direction substantially perpendicular to the extending direction of the blades 30 so that adjacent blades 30 pass through each other, the blades 30 can be used as the power generation device when the blades are berthed. Furthermore, when the blades 30 are rotated in a direction substantially parallel to the extending direction of the support member 16 and the ends of adjacent blades 30 are brought close to each other, a wind receiving surface is formed.
It can be used as a sailing device during towing as described above. In this case, a portion of all the blades 30 may be formed into a flat plate shape.

In addition, in each of the above embodiments, the supporting members 15 and 16 are

The wings may be foldable so that they can be folded toward the rotation axis during sailing. In addition, in the case of a 3-wing type, 2
The blade may be provided to protrude in a 180° direction to form a wind receiving surface, and the remaining blade may be formed to be foldable.

Furthermore, in each of the above embodiments, the present invention was implemented on a plant barge and installed at two locations on the front and rear of the ship's hull, but the number is not limited, and it may be installed at, for example, the four corners of the ship's hull. Furthermore, the present invention is not limited to plant barges, but can be applied to various marine equipment such as columns of jack-up oil drilling rigs or self-lifting work platforms, pneumatic wave power generation ships, floating wave banks, and large floating fishing reefs. can do.

As is clear from the above description, according to the present invention, a sailing device for marine equipment is provided with a rotating body having wings and a wind receiving body, and an electric motor/generator drivingly connected to the rotating body. By configuring the vessel so that the rotating body is rotated by the wind received by the wings, and the ship is sailed by the wind received by the wind receiving body when being towed, the sailing device can also be used to supplement the onboard power, making it possible to This improves the rate and makes it easier to recover the initial investment. In addition, by supplying power to the electric motor/generator from another power source, it can be used as a motor for controlling and driving the wind receiving body during sailing. Coupled with the configuration in which the wind receiving body is provided using structural members, manufacturing costs can be reduced.
Furthermore, it is extremely easy to switch between power generation and sailing, provides a large wind blowing area for sailing, and can withstand high structural loads because it is a horizontally rotating type.
