Abstract

PURPOSE:To facilitate the fixing operation of a waterborne floating body structure without disturbing the passage of ships by installing magnets in the water at the place where the waterborne floating body structure is fixed in a station, and further providing magnets to the bottom of the waterborne floating body structure. CONSTITUTION:Electromagnets 6 are fitted to the bottom of a waterborne floating body structure by directly fixing or by enabling to be suspended in a free position by means of a chain or the like. On the other hand, electromagnets 7 are installed on the bottom of water at the place where the waterborne floating body structure 5 is intended to be installed, and the waterborne floating body structure is fixed on the water surface by regulating the mutual magnetic forces of the electromagnets 6, 7. Further, the waterborne floating body structure 5 is fixed to an anchor 9 or installation foundation of the electromagnets 7 by means of an elastic part 10 such as a spring, and a mooring chain 8 which are connected to the bottom of the structure 5. Furthermore, at the time of typhoon or the like, magnet forces are demagnetized, and the chain 8 is removed, and then the waterborne floating body structure 5 is moved to take refuge. Thus, the fixing operation of the waterborne floating body structure can be easily carried out without disturbing the passage of ships.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for fixing floating structures on water, such as floating piers, floating breakwaters, and floating breakwaters, which are installed on water (including on the sea).

[Conventional technology]

The installation structure of a conventional floating structure on water is explained with reference to FIG.
It is fixed via a chain 3.

This chain 3 is slackened so as to follow the water level deviation, and a sinker 4 is provided in the middle of the chain 3 if necessary.

[Problem to be solved by the invention]

According to such conventional technology, the chain is made to have slack, but this may interfere with navigating ships, and the chain must be long enough so that it does not become taut even at high tide. There is a problem that the fixation of the floating structure deteriorates.

In addition, since a plurality of long chains are installed using anchors, the installation work becomes very large-scale, and there is a problem that the work costs are high.

[Means to solve problems]

The present invention provides a method for fixedly fixing a water floating structure on water, by installing a magnet in the water at a location where the water floating structure is to be fixed, and also providing a magnet at the bottom of the water floating structure. The floating structure is fixed at a desired location on the water by the magnetic force of the magnet and the bottom magnet.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of the first embodiment, and in the figure, 5 is a floating structure on water, and 6 is fixed to the lower part of this floating structure 5 on water, or is suspended downward by a chain or the like and can be placed in a free position. It is an electromagnet attached so that it can be

Reference numeral 7 denotes an electromagnet installed on the bottom of the water at a location where the floating structure 5 is desired to be installed.

Reference numeral 8 denotes a mooring rope or a mooring chain, which connects the water floating structure 5 and the anchor 9, and is provided with an elastic part 10 made of a spring, rubber, etc. in the middle. Note that the lower end does not necessarily have to be an anchor, for example, the electromagnet 7
It may be fixed to an installation stand.

According to the above configuration, by adjusting the magnetic forces of the electromagnets 6 and 7, the water floating structure 5 can be fixed on the water above the electromagnets 6, and the elastic part 10 of the chain 8 can prevent water level deviation. This means that it can be followed and fixed at the same position.

Furthermore, when the water surface becomes rough, such as in a typhoon, for example, by turning off the magnetic force and releasing the lock of the chain 8, the floating structure 5 can be towed and evacuated.

In addition, when the installation position of the said electromagnet 7 is deep, what is necessary is just to make the setting height of an installation position high.

FIG. 2 is a side view of the second embodiment, in which the electromagnet 7 is not fixed to the bottom of the water as in the first embodiment, but the anchor 11 is
An elastic part 13 is attached to the mooring chain 12 attached to the lower end.
The electromagnet 7 is installed at the bottom of the water floating structure 5, and is fixed by a floating body 14 or the like in order to hold the electromagnet 7 at a predetermined depth. The floating structure 5 is placed in place with the electromagnets 6 facing each other.

According to such a structure, the floating structure 5 can be fixed on the water above the electromagnet 7 as in the first embodiment.

FIG. 3 shows the side surface of the third embodiment, and shows the floating structure 5 on water.
A cable or chain 16 having an elastic part 15 is connected to the lower part of the chain 16, and an electromagnet 6 is attached to the lower end of the chain 16.The length of the chain 16 can be adjusted by winding it around a winch or the like. Good to have.

With the above configuration, the floating structure 5 can be placed on the water as in each of the above embodiments, and the distance between the electromagnets 6 and 7 can be determined according to the magnetic force.
They may also be glued together.

However, if the chain 16 to which the electromagnet 6 is attached is lengthened, the stability of the water floating structure 5 on the water will deteriorate, so the shorter the chain 16, the better the stability.

FIG. 4 is a side view of the fourth embodiment, which is a technique that can be used for a water floating structure 5 such as a pier connected to a quay, for example, in which an electromagnet 6 is attached to the side of the water floating structure 5 and the quay is connected to a quay. By attaching the electromagnet 7 to the quay, the floating structure 5 can be fixed along the quay.

Each of the embodiments described above has been explained using an electromagnet, but a combination of an electromagnet on one side and a magnetic material on the other, a configuration using a permanent magnet, and a configuration of a combination of an electromagnet and a permanent magnet are also included in the same technical concept. shall be included.

〔Effect of the invention〕

According to the present invention described in detail above, in a method for fixedly fixing a water floating structure on water, a magnet is installed in the water at a location where the water floating structure is fixed in place, and a magnet is installed at the bottom of the water floating structure. By installing a mooring system, the floating structure can be fixed at a desired location on the water using the magnetic force of the underwater magnet and the bottom magnet, which eliminates the need for conventional mooring ropes or chains strung diagonally on the bottom of the water. This eliminates the risk of interfering with the navigation of the ship, and has the effect of making fixing work easier.

Furthermore, it is possible to carry out evacuation towing if necessary.
It has the effect of eliminating accidents where water flows out and hits and damages ships and other structures during rough times such as during typhoons, and also prevents damage to the floating structure itself and the structures on it.

Furthermore, if a chain having an elastic portion is provided between the floating structure on the water and the bottom of the water, the floating structure on the water can be held in response to changes in the water level.
