BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a device for removing marine organisms attached to ships.

[0002]

2. Description of the Related Art Conventionally, marine organisms attached to the hull of a ship, etc., increase the propulsive horsepower of the ship required for the actual voyage due to the increase in resistance due to the unevenness of the surface of the marine life. These marine organisms are being scraped in the air and washed with water. In addition, dogs are regularly entered, and painting and other maintenance are performed to improve the operational efficiency and durability of ships.

As described above, the conventional maintenance work of a ship is mostly done by hand, which requires not only a large number of workers but also a large number of working days.
Maintenance costs also increase.

From such a point of view, conventionally, an antifouling paint and a surface peeling coating film in which a component for preventing adhesion of marine organisms is mixed in a paint for applying to the outer surface of a hull have been developed and implemented. . However, although this type of paint is primarily effective, it deteriorates or disappears over time, and therefore, when marine organisms adhere to it, a manual cleaning process is required as in the conventional case. For this reason, in order to constantly perform new coating, not only do dogs often appear, but also the coating cost increases.

Further, the surface of the reef in the coastal area is deteriorated due to the secular change (generally referred to as rock burning phenomenon), and fish and shellfish and other marine organisms become inaccessible. This is attributed to the carcass of fish and shellfish and other marine organisms adhering to the surface of the reef and calcifying them.
Therefore, when the substances attached to these reefs are removed, the reefs can be activated to create an environment where fish and shellfish and other marine life can live.

[0006]

As described above, in order to prevent the adverse effects of marine organisms adhering to conventional vessels and other marine facilities and reefs, the number of maintenances must be increased and many workers must do so. Therefore, it is necessary to take a long time, so that not only the cost is significantly increased, but also in the case of a ship, there is a problem that the operating rate is deteriorated.

Therefore, an object of the present invention is to efficiently treat marine organisms attached to a hull with a simple device in a short time, thereby achieving reduction in maintenance period and cost. An object of the present invention is to provide an ultrasonic cleaning device for ships using ultrasonic waves.

[0008]

An ultrasonic cleaning apparatus for a ship according to the present invention is provided with guide rails extending parallel to the water surface on both outer surfaces of the hull of the ship, and one end of each of the guide rails is provided. A band-shaped underwater moving body that is engaged with and extends over the bottom of the hull and is spaced a predetermined distance from both outer side surfaces of the hull is provided, and the entire inner surface facing the hull outer side surface of the band-like underwater moving body. A large number of ultrasonic transducers are arranged over the sea, and means for urging the ultrasonic transducers while moving the underwater moving body along the guide rails are provided. It is characterized in that it is configured to remove the kind at any time.

[0009]

According to the ultrasonic cleaning apparatus of the present invention, by applying ultrasonic waves of several tens of KHz or less, which is the power source for cleaning effect, especially the cleaning work in the sea is facilitated and the equipment is simplified. In comparison with the conventional maintenance of a ship, the device configuration can be remarkably simplified, the number of workers and the working time can be shortened, and the cost can be remarkably reduced. Further, by using ultrasonic waves, many advantages such as not only mere cleaning effect but also sterilization, rust removal, and metal fatigue and damage tests can be obtained at the same time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of an ultrasonic cleaning apparatus for a ship according to the present invention will be described in detail below with reference to the accompanying drawings.

1 and 2 show a typical embodiment of an ultrasonic cleaning apparatus for a ship according to the present invention. That is, in FIGS. 1 and 2, reference numeral 10 indicates a hull of a ship, and guide rails 12, 12 are attached in parallel to both outer side surfaces of the hull 10, and the guide rail 1
The belt-shaped underwater moving body 14 is suspended so as to straddle the bottoms of the hulls 2 and 12. In this case, the underwater moving body 14 is preferably made of a flexible material so as to conform to the shape of the ship bottom. In addition, a large number of ultrasonic transducers 16 are arranged at predetermined intervals over almost the entire inner surface of the underwater moving body 14 facing the ship bottom. It should be noted that at least one end of the underwater moving body 14 is configured so as to be located on the sea surface, and the driving device for moving the underwater moving body 14 along the guide rail 12 and the ultrasonic transducer 16 are attached to this one end. It is preferable to provide an accessory device 18 including a power supply device for energizing.

According to the ultrasonic cleaning apparatus of this embodiment having such a structure, the underwater moving body 14 provided with the ultrasonic transducer 16 is attached to the hull 10 on the sea at all times or when necessary. Cleaning work can be performed at any time. in this case,
The vessel may be in propulsion or in a stopped state. As a means for moving the underwater moving body 14 along the guide rail 12, it is convenient to adopt a means for traveling on the rail 12.

[0013]

As is apparent from the above-described embodiments, according to the present invention, an underwater moving body provided with a large number of ultrasonic transducers is provided, and the underwater moving body is brought close to the object to be cleaned and automatically moved. Therefore, it is possible to effectively remove and clean marine organisms attached to ships and other marine facilities and reefs with a simple structure and with a simple operation. In particular, when cleaning a ship to which the device of the present invention is applied, it can be easily carried out at any time on the sea without putting the ship in a dog, and by using ultrasonic waves, rusting of the hull, fatigue, corrosion, A secondary effect is also obtained in that cracks and the like can be inspected at the same time. Further, the device of the present invention can be installed as an auxiliary equipment inside a conventional floating dog.

The preferred embodiment of the present invention has been described above. However, the present invention is not limited to the above-mentioned embodiment and can be simply and economically applied as a cleaning device for various marine facilities. Of course, various improvements and modifications can be made without departing from the spirit of the present invention.
