DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire, a rope, a chain (anchor) for mooring a marine structure such as a sea berth, an artificial island, a pier, a pontoon, an oil fence, a shield fence, a marine buoy, an aquaculture fishing net, a fish cage, or a ship. Marine organisms attached to long objects such as chains
The present invention relates to an apparatus for removing marine organisms and the like that effectively removes deposits such as barnacles, mussels, and seaweeds) and sludge caught or attached thereto.

[0002]

2. Description of the Related Art Conventionally, the maintenance of underwater structures such as piles for supporting offshore structures and the bottom of ships or water intake channels or pipes of nuclear power plants or thermal power plants has been carried out by using the underwater structures,
It is carried out by removing extraneous matter (shellfish, seaweed, rust, sludge, etc.) such as marine organisms adhering to the surface of a ship bottom, a water collecting channel or the like. Such deposits promote the corrosion of the steel pipe, and the strongly attached marine organisms cause the diameter of the pipe to be distorted and increase the resistance to waves and wind.For example, when used for piers, abnormal vibrations occur. It can cause cracking and destruction. Therefore, it is necessary to periodically remove such deposits. Conventionally, this removal work was mainly performed manually using a wrench rod or a wire brush, but the present inventor has developed a simple removal device using tidal power or wave power, and recently, such an efficient removal device has been developed. Marine organisms can be removed.

[0003] There are various types of marine structures, and relatively large structures or those having simple shapes such as vertical or horizontal are easy to remove marine life and the like by the apparatus.
For ropes and wires that anchor such marine structures, such as ropes and wires, or those that have irregular shapes such as chains, are effective in removing marine organisms and the like. There is no means, and removal has been performed manually by using a wrench rod, a wire brush, or the like as in the past. Such ropes, wires, chains, etc., are relatively easy to be overlooked, but when marine organisms settle and grow, the diameter of the ropes, etc., can be tens to hundreds of times larger. In addition, there is a problem that a structure that should originally be floating sinks or tilts. For this reason, there is only removal by moderate human power in bad conditions, and if the number is large, it can reach hundreds to thousands, and because it is marine or water work,
Depending on weather conditions such as wave winds or tides and currents, there are many dangers, and a large number of workers and sometimes divers are required, and long-term removal work increases construction costs, unstable work period, unsafe It is a factor such as work. Due to work hazards, such ropes, wires, chains, etc. may even be discarded.

[0004] For this reason, a special paint such as a biological control agent or a substance generating toxic ions, which makes it difficult for adherents (shellfish, seaweed, etc.) to adhere, is applied so that the above-mentioned manual work is not required. Although various measures have been taken, such as adopting a method to control or kill the attachment of marine organisms, chemicals such as biocontrol agents contaminate not only workers but also nearby sea areas and cause environmental pollution problems. I do. In practice, it is impossible to prevent the marine organisms from adhering for a long period of time, and there is also a problem that it is inevitable that the marine organisms are periodically removed manually.

[0007]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of the entire structure of the present apparatus. A pair of freely rotating rollers 1,
1 are arranged in parallel at a substantially central position on the same plane with a slight space therebetween. These rollers 1 and 1 are mounted on a ring-shaped upper frame 2 or lower frame 6 by arms 3.
Is supported through. Since these frames 2 and 6 can collide with various instruments during operation, FIG.
It is desirable to be a circular ring for strength like
It may be rectangular or other shapes. In this sense, the ring-shaped upper and lower frames 2 and 6 of the present invention include other shapes such as rectangles. Further, as shown in FIG. 1, it is better to support both ends of the roller 1 with two arms 3 so as to be able to resist the deformation force, but a cantilever type may be used. This one
The pair of rollers 1, 1 are urged toward each other on the arm 3 by means such as a spring 4. A hydraulic cylinder can be used instead of a spring. As a result, the roller 1 always elastically contacts the long object 5 such as a rope, a chain, etc., from which the sea creature or the like sandwiched between the rollers 1, 1 is to be removed. If there are irregularities or protrusions such as chains, a certain load is applied to the spring 4, but when a force greater than the elastic force of the spring 4 is applied, the spring 4 passes between the rollers 1 and 1, where the present removal device Movement is not hindered.

In FIG. 1, two pairs of parallel rollers 1, 1 are arranged on the upper and lower surfaces of one circular upper frame 2 so as to intersect at right angles with each other on different planes. Although the right angles are shown in this figure, they do not always have to intersect at right angles on different planes, and they can be arranged at a fixed angle (an angle other than a right angle). Although two pairs of rollers 1 and 1 are provided on the upper surface and the lower surface of the circular upper frame 2, it is also possible to install one pair of these rollers on one frame. However, as described above, providing a pair of rollers on the upper and lower surfaces of one frame, respectively, has a feature that the entire apparatus can be made compact.

A lower frame 6 of the same structure is installed below the upper frame 1 in FIG. Although the number of frames is two in FIG. 1, the number of frames may be increased to three or more (multi-stage). A plurality of casters 8 are installed on the lowermost frame, so that the entire apparatus can be easily transported for assembly or cleaning on land. The upper frame 2 has four rods 7 and springs 9 and 1 with respect to the lower frame 6.
With 0, it is elastically supported while maintaining a predetermined interval. Thus, the frame itself can be moved up and down within the range of elasticity by the springs 9 and 10.

FIG. 2 shows a chain 5 with a roller 1,
1 shows a partial perspective view sandwiched between the two. After being sandwiched between the upper rollers 1 and 1 urged in the direction of each other by the spring 4, the chain 5 is sandwiched between the lower rollers 1 and 1 similarly urged by the spring below and moves. While being repeatedly contacted between the rollers, sea life such as shellfish attached to the chains is removed. Although the angles of the upper and lower rollers 1 intersect at right angles on different planes in the figure, if they are arranged at angles other than right angles, the direction of the rollers 1 with respect to the chain can be changed according to the angles. The roller 1 that comes into contact with the chains to which the marine organisms adhere is made of hard plastics, but it is also possible to use seawater-resistant metal or hard wood. There is no particular limitation as long as the material has strength, toughness, abrasion resistance, and seawater resistance and does not damage ropes, chains, and the like.

Since the chain 5 has a step (joint step) for each wheel as shown in FIG. 2, when passing between the rollers 1 and 1,
Although it is displaced for each wheel against the elasticity of the spring 4, as described above, since the space between the frames 2, 6 is supported via the springs 9, 10, the spring 4 and the frame 2, Due to the elasticity of the springs 9, 10 between the six, the irregular movement can be absorbed, the unevenness can be smoothly overcome, and the removal object can be effectively prevented from being caught. When this device goes up and down, it comes into contact with chains, etc., causing some vibration. As shown in FIG. 3, a fluid pressure vibration generator 11 may be provided between the frames 2 and 6 to forcibly apply vertical vibration between the frames 2 and 6 to amplify the vibration. This makes it possible to further enhance the effect of removing the sea life by the rollers 1, 1 that support the chain to which the sea life has adhered between the upper and lower frames 2, 6. Reference numeral 13 denotes a supply pipe for supplying a fluid such as air to the fluid pressure vibration generator 11, and two fluid pressure vibration generators 11 are shown in FIG. This fluid pressure vibration generator 11
The number can be more than one, but it is necessary to arrange the frames in a well-balanced manner. When the frames are installed in multiple stages, the fluid pressure vibration generator 11 may be attached to each stage.

Further, as shown in FIGS. 1 to 3, a high-pressure jet nozzle 12 is arranged on an arm 3 supporting the rollers 1, 1, and a direction of a chain to which sea creatures are attached is parallel to the rollers 1, 1. That is, a high-pressure jet water stream or the like can be jetted toward the center. By jetting the jet water stream or the like, the effect of removing sea creatures attached to the chains can be further enhanced. Also, the removed sea creatures are likely to remain on the rollers 1 and 1 and the space between the rollers 1 and 1 may be clogged. However, the sea creature residue removed by the injection of the air or the like is effectively eliminated. Play a role. In the figure, the high-pressure injection nozzle 12 is provided only at the uppermost stage, but may be provided at each stage of the roller.

The upper and lower frames 2 and 6 are each configured to be vertically divided into two semicircles. Reference numeral 14 denotes the pivot, which can rotate around the pivot 14. The other ends 15 of the semicircular upper and lower frames 2 and 6 are
In a state where they are combined in a circular shape or the like, they can be fixed by an open / close pin (not shown). In order to attach the chains or ropes to which the marine organisms are attached to the apparatus (pass between the rollers), first remove the open / close pins from the semicircular upper and lower frames 2 and 6 and rotate them by a predetermined angle around the pivots 14. And open. In this state, the chains and ropes to which the marine organisms are attached are set from the side so as to come to the center position, and the upper and lower frames 2 and 6 are returned to the original positions and sandwiched between the upper and lower plural rollers 1, and the upper and lower frames 2 And the other end 1 of 6
5 is fixed with an opening / closing pin. This operation can be easily performed on land, at sea level or in the sea.

After the chains or ropes 5 to which the marine organisms are attached are mounted on the apparatus, the apparatus is moved along the chains or ropes by its own weight or a winch, and is arranged in a plurality of stages having different directions. Sea organisms such as shells are forcibly removed between the freely rotating rollers 1 and 1. At this time, the fluid is supplied to the fluid pressure vibration generating device 11 to generate vibration between the upper and lower frames 2 and 6, and the chain and the rope 5 are given a squeezing operation by the rollers 1 and 1, thereby obtaining an effect. Sea creatures can be removed. In addition, high-pressure injection nozzle 1
Seawater attached to the chains and ropes 5 is blown off by jet water jets sprayed from
The removal residue accumulated between them is removed at the same time. The lifting of the device can likewise be done with a winch or an air balloon. At the time of this ascent, marine organisms can be similarly removed.
