Description

[Detailed description of the invention] This invention is designed to improve the efficiency of ships, specifically, berthing and unberthing operations at mooring facilities, and prevention of contact and collision with other ships while anchored or sailing at sea. Alternatively, the present invention relates to a ship equipped with a completely new navigational aid device that can perform various types of navigational assistance, such as preventing collisions and contact with quays when navigating in narrow waterways such as canals, entering and exiting docks, and automatically guiding the ship.

For example, berthing and mooring work for ships at mooring facilities such as quays, piers, and floating jetties has typically been carried out as follows.

First, the vessel is brought close to the mooring facility by a complex maneuver that combines rudder operation and forward/reverse operation of the propeller, or with the assistance of tugboats if necessary, and then from the bow and stern of the vessel. Throw one end of the mooring line to the mooring equipment, then tie and fasten one end of the mooring line to a mooring pole etc. at the mooring equipment, and then use a winch etc. to tie the mooring line from the other end at the bow and stern of the vessel. While winding up (sometimes the ship ties one end of the mooring line, and the mooring equipment winds the mooring line from the other end), pull the ship to the mooring equipment, bring it alongside, and then tie the other end of the mooring rope. The vessel was moored by tying it to a mooring post, etc. In other words, for such berthing and mooring work, two people are required each on the ship side and the mooring equipment side.
It was an extremely inefficient work that required four workers in total and was laborious and time consuming. In addition, docking work for other vessels or offshore structures is also inefficient work, similar to the above-mentioned berthing and mooring work.

In addition, when we look at the work of unberthing from the mooring equipment and marine structures mentioned above, first the mooring lines tied to the mooring poles are released, and then the work is done either by complicated maneuvers or with the assistance of tugboats. Just like the above-mentioned berthing work, the task of moving the ship away from the berth was extremely troublesome and inefficient.

The inefficiency of such berthing and unberthing work is due to the fact that, firstly, the work (vessel maneuvering) to move the ship sufficiently close to or away from the mooring facility is extremely troublesome and difficult, as well as requiring a great deal of effort. that it takes time,
Secondly, since mooring lines are used to moor the ship, a great deal of effort and time is required for tying, untying, and pulling the lines.

The present invention was developed in view of the above-mentioned conventional circumstances, and its purpose is to reduce the number of workers who can carry out berthing and mooring work for mooring equipment, landing work on other vessels or marine structures, and even unberthing work. Moreover, it can be carried out easily and efficiently in a short time, and it can also be used to prevent collisions and collisions with other ships while anchored at sea or while sailing, or when navigating narrow waterways such as canals or when entering and exiting docks. We provide ships equipped with convenient navigational assistance devices that can perform various types of navigational assistance, such as preventing contact and collision with quay walls, and even automatic hull guidance. The aim is to provide a suitable means for solving the problem of labor saving in flight operations.

First, an embodiment of the present invention will be described based on the drawings.

FIGS. 1 and 2 show a plurality of magnetic generators 1, each of which emits magnetism toward the outside of the hull, as a navigational aid device, installed on both left and right outer walls of the parallel portion of the hull, respectively.
A first embodiment of a ship according to the present invention is shown in which the following are arranged at equal or approximately equal intervals in the ship length direction.

FIG. 3 shows the structure of the magnetism generating device 1, the mounting structure of the magnetism generating device 1 on the hull, and the structure of the electric circuit for the magnetism generating device 1.

The magnetism generator 1 has an electromagnet unit 3 built into a watertight case 2, and only the side plate 2a on the outer side of the hull of the watertight case 2 is made of magnetic material, and the other side plates are made of magnetic material. All of them are made of non-magnetic material, so that the magnetism generated by the electromagnetic unit 3 can be emitted only towards the outside of the hull without weakening, and in other directions, especially towards the inside of the hull, as much as possible. It is configured to block it and prevent it from emitting.

A cylindrical support case 5 is fixed inside the hull outer plate 4 on the hull outer wall. The outer end of the support case 5 is formed as a storage area for the magnetism generating device 1 and is opened toward the outer side of the hull, and all other parts are constructed in a watertight manner. A flow counter-pressure cylinder 7 that is controlled to expand, contract, and stop by a three-position electromagnetic control valve 6 is built into and fixed to the inner end of the support case 5 inside the hull. Also, inside the support case 5 is a sliding rod 8 that slides toward the outside of the hull and inside the hull as the hydraulic cylinder 7 expands and contracts.
is fitted inside. On the other hand, a connecting rod 9 made of a non-magnetic material is provided on the inside and outside of the hull of the magnetism generating device 1.
is fixed. This connecting rod 9 is swingably connected to the sliding rod 8 by a ball joint type universal connection. Further, a relatively strong compression made of a non-magnetic material is applied from the inner and outer surfaces of the magnetic generator 1 to the outer end surface of the sliding rod 8 on the outer side of the hull, while being fitted onto the connecting rod 9. A spring 10 is provided.
With the above configuration, the magnetic generator 1 can be repositioned between a stored position within the hull and a protruding position outside the hull, and can be oscillated relative to the outer wall of the hull, that is, relative to the hull. It is installed so that its relative position can be changed freely. The non-magnetic surface of the magnetism generator 1, the area around the connecting rod 9 and the spring 10, and the outer end surface of the sliding rod 8 are as follows:
It is covered with a continuous non-magnetic elastic material 11, and
The ability of the magnetic generator 1 to block the magnetism directed toward the inside of the hull is further enhanced, and the shape-retaining elastic force of the spring 10 combined with the biasing force directed toward the outside of the hull causes the magnetism generating device 1 or the hull to It is configured to maintain the relative attitude of the magnetism generating device 1 with respect to the ship's body constant unless a forced external force is applied, and to also serve as a shock absorber when the magnetism generating device 1 is stored.

The magnetic generator 1 connects a transformer 12 that can continuously adjust the magnitude of the output voltage to an inboard AC power source 15 via a rectifier 13 and an on/off switch/current direction switch 14 for converting AC to DC. By adjusting or switching the transformer 12 and the switching device 14, the generation of magnetism can be stopped or the desired polarity (N pole or S pole) and desired strength can be changed. It is configured to generate magnetism. In addition, 16 is a fixed cord, 17 is a terminal, and 18 is a compression coil cord that expands and contracts in response to changes in the retraction and protrusion position of the magnetic generator 1, and is always biased in the contracting direction, and is inserted into the support case 5. The area from the hole 19 through which the octopus compression coil cord 18 is passed through to the terminal 17 is watertightly sealed.

Operating tools 20, 21, 22 for the three-position electromagnetic control valve 6, transformer 12, and switch 14, respectively
All of these are integrated into an operation panel 24 provided in the wheelhouse 23 on the bridge, and operations such as turning on/off the magnetic generator 1, changing polarity, adjusting the magnetic force strength, and switching the protrusion/retraction can be performed from the wheelhouse 23. It is configured so that it can be easily controlled remotely.

25 is a polarity indicator for displaying the polarity of magnetism emitted toward the outside of the hull of the magnetism generator 1;
is connected to. Then, the magnetic generator 1 is N
When the magnetic generator 1 is emitting magnetic pole, only the red lamp with the letter N lights up, and when the magnetic generator 1 is emitting south pole magnetism, only the blue lamp with the letter S lights up. By configuring both of the lamps to be off when the magnetic field is not being emitted, it is possible to visually confirm the type of magnetic polarity that is being generated by the magnetism generating device 1 toward the outside of the hull. It's like this.

In the first embodiment, a ship is shown in which the magnetic generator 1 is installed only on both sides of the hull, but depending on the type of ship or the purpose, it may be installed only on the bow or stern. , it may be provided over the entire circumference of the hull side.

In addition, although the magnetic generator 1 is installed at a fixed position slightly above the water line, such a configuration is suitable for passenger ships and self-defense vessels where the water changes little, but This may be inconvenient for oil tankers that change. For such a ship, as in the second embodiment shown in Fig. 4, a plurality of mutually independent electromagnetic units 3 are installed in the case 2 in a row in the height direction of the ship, and according to the situation. It may be configured to selectively energize one or more electromagnetic units 3 located at desired heights.

The ship with the above configuration, as shown in Figure 5,
It has various operational advantages.

A shows how a ship is berthed according to the present invention on a floating pier A, which is an example of a mooring facility in which at least the side walls are made of a magnetic material such as steel. That is, after the ship is stopped at an appropriate position along floating pier A and a little away from it, the magnetic generator on the side closer to pier A is protruded from the ship's hull, brought closer to pier A, and the magnetic generator is moved toward pier A. (In this case N
By emitting a magnetic field (which may be either a pole or a south pole), an attractive force is generated between the pier A and the magnetic generator, and this attractive force causes the magnetic generator to adsorb and contact the pier A, and then the magnetic generator is brought into contact with the pier A. By pulling it into the storage position inside the hull, the hull is pulled toward the pier A side and berthed and moored. At this time, more reliable and efficient mooring work can be carried out by using the above-described magnetic strength adjustment operation of the magnetic generator.

In addition, by stopping the magnetic generation of the magnetic generator and positioning the device to protrude outside the ship's hull, it is possible to make it extremely easy for the ship to leave the berth from the berthed state with the magnetic generator stored in the retracted position. It can be done easily.

As mentioned above, the ship according to the present invention can easily and quickly carry out mooring and unberthing operations for mooring equipment on its own, without the need for assistance from tugboats, etc., and with only one worker (helmsman). It can be done. Particularly in the case of very short moorings, it is sufficient to attach the hull to the mooring equipment using magnetic force alone, and the mooring lines can be used to tie the vessel to the mooring line or untie it when leaving the vessel. There is no need for such trouble. In addition,
As can be seen from examples such as magnetic cranes, it is possible to obtain a fairly strong magnetic force.

(b) and (c) have at least a side wall made of magnetic material, and
Alternatively, it shows how a ship according to the present invention arrives at an offshore structure C such as an offshore plant. Such landing operations (and subsequent disembarkation operations)
Similarly to the above-mentioned berthing and mooring (de-berthing) work, this work can also be carried out efficiently by one worker and by one's own efforts.

In addition, as shown in (d), (e), and (f), the ship according to the present invention can be used for other ships made of magnetic materials such as ship B and marine structure C.
Arrival at the ship and tow it, or adsorb the cargo D made of magnetic material and transport it without loading it onto the hull, or, as shown in G, land on another ship B made of magnetic material and carry it in parallel. It has various conveniences such as anchorage. Furthermore, as shown in FIGS. 1 and 2, ships according to the present invention can prevent contact with each other due to turning around while at anchor or collisions when passing each other by emitting magnetism of the same type of polarity. In addition, if a navigation control system using magnetism is realized in the future, the magnetic field emitted by the system will be used as an information medium to detect the presence or location of one's own ship to other ships and control departments. It is also possible.

Note that the ship according to the present invention can be used more effectively by providing the above-described magnetic generator on the mooring equipment or offshore structure side.

FIG. 6 shows an example of this, in which magnetism generating devices 1 are provided on a quay 29 serving as mooring equipment. The magnetic field generator 1 and its related equipment configuration are almost the same as those provided on the ship according to the present invention, so a description thereof will be omitted, but the configuration will be clear from the drawings. Note that 30 is a rubber fender fixed to the quay 29, and the magnetic generator 1 is configured to be able to change its position between a retracted position inside the fender 30 and a protruding position outside. There is.

If the mooring equipment or offshore structure is configured as described above, the advantages of the present invention in terms of vessel operation will be further enhanced.

For example, when berthing and mooring, by making the polarity of the magnetism emitted from the ship and the magnetism emitted from the mooring equipment different from each other, a greater attractive force is created between the two, making the berthing work even easier. . Furthermore, by making the polarities of the magnetism that is emitted by both the same to generate a repulsive force between the two, it is possible to more reliably leave the ship from the mooring facility. In addition, as shown in Figure 7A, by making the polarity of the magnetism emitted from both banks of the narrow waterway E and the magnetism emitted from the ship the same, the ship can be safely protected without contacting or colliding with the shore. It is possible to navigate the narrow waterway E. The same applies to the case of entering and leaving dog F shown in (b). Furthermore, by continuously moving the position of magnetic generation from the shore or dockside over time, it is possible to use magnetic force to guide a ship without driving the ship's propulsion device. .

In summary, the ship according to the present invention is equipped with (A) a plurality of magnetic generators capable of generating magnetism from the inside of the ship toward the outside of the ship as a navigational aid device on each of the left and right outside walls of the ship; (B) The polarity of the magnetism emitted by the magnetic generator 1 is N.
(C) The magnetism generating device 1 is configured to be able to adjust the strength of the magnetism emitted by the magnetism generating device 1, and (D) the magnetism An essential structural requirement is that the generator 1 is configured to be able to change its position between a stored position within the hull and a protruding position outside the hull.

And, because of the above-mentioned characteristic structure, various excellent effects as described below have been achieved.
That is, (i) As detailed in the explanation of the embodiment, when docking at a mooring facility or landing on another ship or offshore structure, magnetic By using this together with the generation of attraction based on magnetism, the hull can be brought closer to mooring equipment easily and in a short time, and the mooring can be achieved using the attraction of the magnetic generator, which is much easier than conventional methods. This eliminates the trouble of tying and winding mooring lines, and can be done easily and quickly with fewer workers. (ii) With regard to unshore work, by combining the operation of de-energizing the electromagnet with the operation of protruding the magnetic generator, (iii) By being able to adjust the strength of the magnetism emitted by the magnetic generator, it is possible to move the ship closer to mooring equipment, etc. Then, when carrying out berthing or unberthing work that involves going far away, a sufficiently strong magnetic field should be used to generate a large attractive force.
On the other hand, when the ship is moored after berthing, a relatively small attraction force is sufficient to generate weak magnetism, which allows for efficient use of power depending on the purpose, and (iv) multiple magnetism generators. As explained in detail in the description of the embodiment, by arranging the devices in the direction of the ship's ship on both the left and right outer walls of the ship's hull, and by switching the polarity of the magnetic field it emits, It can also be used as a multi-functional navigation aid device, such as preventing contact and collision between ships while navigating, preventing contact and collision with quays when navigating in narrow channels and entering and exiting docks, and automatically guiding the ship. Furthermore, (v) during normal ocean navigation when there is no need to use it as a navigational aid, the magnetic generator can be stored inside the hull, so there is no inconvenience that the magnetic generator becomes a resistor when exposed to waves, etc. There is also.
