Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an underwater structure (for example, a steel pipe pile, an H-shaped pile, a square pile, a concrete pile, a vertical pile, a horizontal pile, etc.) for supporting an offshore structure such as a sea berth, an artificial island, and a pier. Materials, diagonal materials, bridge piers, pier legs, embankments), or buoyant debris that removes marine organisms and other debris that have adhered to the hull of the ship's side or bottom using wave, wind, or tidal power It relates to a removing device.

[0002]

2. Description of the Related Art Conventionally, maintenance of underwater structures such as piles for supporting offshore structures and ship bottoms has been carried out by removing adhering substances (shellfish, seaweed, rust, sludge, etc.) adhering to the surface of the underwater structures and ship bottom. It is done by removing. 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. In a concrete structure, a phenomenon is observed in which marine organisms remove sulfur contained in the concrete, and the concrete structure, which appears to be strong, gradually wears out from the surface. For this reason, it is necessary to periodically remove such deposits, but this removal operation is currently performed mainly by a human power using a wrench or a wire brush.

[0003] However, many of the marine structures have hundreds to thousands of installations, and work on the sea or on the water. Therefore, there are many dangers depending on weather conditions such as wave wind or tides and currents. In addition, a large number of workers, and in some cases, divers, are required, and the long-term removal work increases construction costs,
This has caused factors such as unstable work periods and unsafe work. This also applies to the work of removing extraneous matter adhering to the hull and the bottom of the hull, especially for ships. At present, maintenance work is being carried out.

[0004] For this reason, a special paint such as a biocontrol agent that makes it difficult for adherents (eg, shellfish and seaweed) to adhere to underwater structures so as not to require the above-mentioned manual work, Although various measures have been devised such as attaching a pile cover for protecting the underwater structure, the biocontrol agent may harm the human body, and may also contaminate nearby sea areas. And in fact, it is not possible to prevent the marine organisms and the like from attaching thereto,
Again, there was the problem that periodic manual removal was unavoidable.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has been made in consideration of the problem that a long adhering substance removing structure that contacts the surface of an underwater structure is subjected to wave power (tide flow, ebb and flow). Etc.), so that it can move not only in the vertical direction but also in various directions, and this movement effectively removes deposits such as concrete and steel pipe piles or the bottom of the ship, and further removes the deposits Provided is a buoyancy-type adhering substance removing device for an underwater structure, which can be attached along the outer shape of concrete or a steel pipe pile from which the structure is to be removed. For this purpose, the present inventor has already invented a basic buoyancy-type attached matter removing apparatus (Japanese Patent Application No. 9-164374). According to this, it was found that seawater such as shellfish and seaweed adhered to concrete and steel pipe piles had an excellent adhering matter removing effect that most of them were removed within a few days.

However, since the extraneous matter is removed in a very short time or a short period of time, there is no time for attaching and detaching the extraneous matter removing device, and the extraneous matter removing structure is significantly worn. After removing further deposits,
A problem has arisen that if the adhering material removal structure is not removed promptly from the installation site, underwater structures such as concrete and steel pipe piles may collide with this adhering material removal device and wear away (still misleading. It should be noted that the basic invention is still effective when the deposits are removed within a short period of time). Therefore, the life of the adhering material removing structure can be extended relatively slowly (slowly) and steadily, and the adhering material can be removed more stably without the adhering material remaining on the entire area where the sea organisms adhere. Provide a device that can be removed cleanly. In addition, the present invention provides a buoyancy-type debris removal device for underwater structures, which can reduce the frequency of replacement and removal of the device and can operate stably.

[0007] In general, marine organisms such as shellfish and seaweed often attach and live near the water surface (directly above and below the water surface), and gradually increase in size, including dust and mud floating on the sea surface. The above-mentioned invention already proposed is extremely effective in removing such deposits. However, there are other marine life that extends over several tens of meters below the surface of the water. In the above invention, in order to cope with such a case, a plurality of buoyancy type adhering substance removing devices can be arranged below the water surface. However, since the buoyancy type adhering matter removing device has a limited width to move up and down due to wave force and tidal force, it is difficult to remove the adhering material of underwater structures without gaps. A number of buoyant debris removal devices had to be placed in the water. The present invention provides an apparatus that has a simple structure and that can remove neatly, such as marine organisms, over the entire area of the adhering area, and can cleanly remove the adhering substances. In addition, the present invention provides a buoyancy-type adhering substance removing apparatus for underwater structures, which can reduce the frequency of replacement and removal of the apparatus and can operate stably.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings. First, referring to FIGS. 1 to 6, a buoyancy type adhering substance removing apparatus A of the present invention includes a plurality of piece members 11 and a plurality of rings mounted around the piece member 11 so as to freely rotate. 5; a fastener 2 such as a bolt and a pin for fastening the piece members 11 to each other; a float 3 attached to an appropriate portion of the deposit removing structure 1 as necessary; It consists of a mounting bracket 4 and the like to be attached to the attached matter removing structure 1. The ring 5 is shown only in FIG. 5, and the ring 5 is not shown in FIGS. This is because the ring 5 was removed so that the internal structure of the bridge member 11 and the like could be easily understood. The ring 5 is connected to the piece member 11.
Figure 1
-Easy assembly in FIG. In the present invention, one or a plurality of rings 5 are fitted around the piece member 11 shown in FIGS.

The piece member 11 and / or the ring 5 are preferably made of a material floating on the water surface. in this way,
When other accessories are not used, the bridge member 11 or the ring 5
Is floating on the sea surface, so that the buoyancy-type attached matter removing device A can be constituted by this alone. However, as described later, a buoyancy type adhering substance removing device is provided in two stages, and these are hung by steel fittings, or a net for collecting the removed adhering substance by a net-like collecting means is used as a buoyant type adhering substance. When it is arranged below the removing device A and it is hung by a steel bracket, the piece member 11 or the ring 5
Can not be kept up. Therefore, in such a case, the float is attached to an appropriate portion of the piece member 11 by a necessary number to provide buoyancy.

It is preferable to use a resin such as polypropylene, polyethylene, nylon, Duracon, hard rubber or the like for the material of the bridge member 11 and the ring 5. But,
Materials other than these resins (for example, wood, leather, ceramics, metal, etc.) may be used. The properties required of these materials are that they have a certain level of abrasion resistance and can remove deposits such as shellfish and seaweed, but can avoid abrasion of underwater structures such as steel pipes and concrete. You are only restricted. As shown in the figure, a tongue receiving slot (elongated hole) is provided at one end of a substantially rectangular piece 11.
The tongue piece 11b is formed at the multi-end portion of the end piece 11a so that the tongue piece accommodation slot 11a and the tongue piece 11b of the adjacent piece member 11 can be fitted to each other. Here, the “tongue piece” refers to a member projecting from the piece member 11 like a tongue. Reference numeral 100 indicates each fitting surface.
Further, insertion holes 11c are provided in the parallel wall portions on both sides of the tongue piece accommodation slot portion and the tongue piece 11b.

The means for joining the bridge members 11 to each other are a bolt 22, a nut 32 and a pin 12 with a spring.
Other means may be used. However, the above-described readily available connectors are most preferred. Tongue piece 1 of piece member 11
After inserting 1b into the tongue piece accommodating slot 11a of the adjacent piece member 11, it is joined by the bolt 22, the nut 32 and the spring-loaded pin 12. Thus, the plurality of bridge members 11 constitute a link mechanism, and receive an external force such as a wave force and a tide force, and freely deform around the underwater structure B while moving up and down. In the above case, the example in which the piece member 11 is joined so as to freely move by the link mechanism has been described, but the attached matter removing structure 1 has a specific shape (for example, a rectangle) of the underwater structure B.
If it is desired to fix and maintain a fixed shape to fit the
By firmly fastening with the nut 2 and the nut 32, the fixed shape can be maintained. A square piece member 11 shown by a two-dot chain line in FIG. 1 is an example thereof.

The spring-loaded pin 12 is a means that can be easily joined at the site. The spring-loaded pin 12 is inserted into the insertion hole 11c of the piece member 11, and the U-shaped spring rod 12b is turned up and down to rotate the pin. 12a. Spring rod 12b
The U-shaped portion is curved so that the periphery of the square piece member 11 can be clamped. FIG. 1 shows this pin 1 with a spring.
2 before insertion into the insertion hole 11c of the bridge member 11,
FIG. 2 shows a state in which the bridge member 11 is fastened by the spring-loaded pin 12. As described above, since the joining with the spring-loaded pin 12 can be easily operated, many of the plurality of bridge members 11 are joined in advance with the bolts 22 and the nuts 32, and
It is most efficient to join the two on site using this spring loaded pin 12.

As shown in FIG. 6, the apparatus for mounting the float 3 on the bridge member 11 has a mounting hole 24a from one side of the frame 14 large enough to fit outside the bridge member 11 with a small clearance. It has a structure provided with a plate 24. With the mounting plate 24 facing outward, the bridge member 11 is inserted into the frame body 14 and joined to the bridge member 11, and the mounting plate 24 and the mounting flange 13 protruding from the float 3 are bolted and nuts or the like. The piece member 11 and the float 3 are joined by tightening. The float 3 is made of foamed plastic, preferably has a hollow interior and is manufactured by an injection molding method, but may be manufactured by another material or method. The flange 13 is formed integrally with the float 3 so as to correspond to the mounting plate 24.

As shown in FIG. 5, the ring 5 is
It is mounted so that it can rotate freely around The ring 5 can be composed of one or a plurality of pieces so as to cover substantially the center of the piece member 11. Further, this ring 5 is used as a connector between adjacent piece members 11, that is, the bolt 2.
Between the nut 2 and the nut 32 or the spring-loaded pin 12, the piece member 11 can move left and right along the length direction. Since the bridge member 11 is linked to the adjacent bridge member 11 with each other, the attached matter removing structure 1 to which the bridge member 11 is connected can be freely deformed around the underwater structure B. Since the ring 5 that covers the outer periphery of the piece member 11 is rotatable and movable left and right as described above, only the ring 5 moves and rotates left and right due to wave force or tide force to the underwater structure B. Can be in direct contact. Therefore, this ring 5 is
In this case, the underwater structure B and the piece member 11 do not come into direct contact with each other unless the ring 5 is worn and most of the ring 5 is worn. However, since the piece member 11 itself originally plays the role of removing the adhered substance, the underwater structure B
There is no particular problem even if it comes into direct contact with the device. As will be described later, the ring 5 is intended to reduce the abrasion of the ring 5 at the same time as performing the action of removing the deposits relatively slowly and slowly over time and densely. If this function is to be maintained, the ring 5 may be replaced when the wear of the ring 5 is anticipated.

The ring 5 rotatable and movable left and right on the piece member 11 has an important function of the present invention. As a result, the ring 5 collides softly with the underwater structure B, and is particularly effective for removing the upper and lower scrapes of the underwater structure B which has a distorted shape (diameter) to which sea creatures adhere. And wear of the ring 5 is significantly reduced. The ring 5 is a link member 1
1 can be easily attached or detached, so that it is very easy to replace. In addition, even if the attached matter removing device is left for a long time after the attached matter of the underwater structure B is removed, the ring 5 only soft-touches, so that the underwater structure B is worn or damaged. Is also significantly reduced. Thus, the piece member 11
The upper rotatable and laterally movable ring 5 reduces its own wear, and also maintains the effect of removing abnormal projections of the underwater structure B (due to the adhesion of marine organisms, etc.) and is flatter. It has a feature that the surface of the underwater structure B is relatively hardly damaged.

As shown in FIG. 5, a bolt 22 and a nut 32 or a spring-loaded pin 12 are used to function as a stopper for the ring 5 which moves left and right along the length of the bridge member 11. Another stopper may be provided instead of the bolt 22 and the nut 32. However, it is most effective to use the existing bolt 22 and nut 32 or spring-loaded pin 12 in terms of cost. In this case, in order to have a role of a stopper, the bolts 22 and nuts 32 for providing the link mechanism of the piece member 11 are made slightly longer to project from the piece member 11 so as to collide with the ring 5. It is necessary.

When using the buoyancy type adhering substance removing apparatus A for underwater structures constructed as described above, first, the plurality of piece members 11 are torn into the tongue piece receiving slots 1 of the adjacent piece members 11.
After fitting the tongue pieces 11b to each other, the insertion holes 11c
Through the bolt 22 and fix it with the nut 32. Piece member 11
The bolt 22 and the nut 32 are fixed only at the tip so that they can rotate with each other. When fixing the piece members 11 so as to maintain a constant angle, it is necessary to tightly tighten the bolt members 22 and the nut 32 so that they cannot rotate. In addition, as shown in FIGS. 1 and 6, a float 3 is attached as needed.

As described above, the buoyancy type adhering substance removing apparatus A to which the piece member 11 is connected is floated on the water surface and carried to the mounting site by an operator such as a diver while dragging there.
Around the periphery of the frame, where the pieces 1 at both ends
After the tongue pieces 11b are fitted into the one tongue piece accommodation slot 11a, the pin 12 with a spring is inserted into the insertion hole 11c, and the U-shaped spring rod 12b is hooked on the tip of the pin 12a to complete the mounting.

When the underwater structure B is, for example, a rectangular pillar of a pier or a breakwater, and the buoyancy type adhering material removing apparatus A is to be maintained in that shape, the two pieces 11 corresponding to the corners of the pillar are fixed at right angles. And a square shape can be maintained by tightly tightening the bolts 22 and nuts 32 used therein. As described above, since each piece member 11 is rotatable and relatively angle-adjustable by the link mechanism, the adhering substance removing device A can be connected to the underwater structure B by selecting the number of connected piece members 11. Can be arranged in a similar manner along the shape of the underwater structure, and the adhering substance removing device A is moved toward and away from the underwater structure B and up and down under the force of waves, wind, tide, etc. The ring 5, which rotates and moves left and right, comes in direct contact with the underwater structure B, and relatively slowly and densely repeatedly collides against the attached matter with time, thereby performing the removing action. Thereby, attached matter such as shellfish and seaweed can be effectively removed.

Next, a description will be given with reference to FIG. In this case, the attached matter removing structure 1 is mounted around an underwater structure B 'extending horizontally or horizontally. This horizontally or horizontally extending underwater structure B 'is, for example, a vertical 2
It is used when connecting the piles of books sideways. Such a structure B ′ may be placed below or slightly below the surface of the water, or may be immersed diagonally in the middle of the water. Especially near the water surface, adhesion of shellfish and algae is remarkable.
In this case, the attached matter removing structure of the present invention is equivalent to a vertically arranged attached matter removing structure 1 (the shape of the attached matter removing structure is also horizontal when it is arranged vertically). Since the arrangement is the same, the same reference numeral 1 is used). Therefore, the plurality of piece members 11 continuously arranged along the length thereof and one or more rings 5 mounted so as to freely rotate around each piece member are arranged along the vertical plane. are doing.

In FIG. 7, there is a float 3 on the upper part, and the attached matter removing structure 1 in which a plurality of bridge members 11 are connected to the float 3 is on the water surface so as to surround the underwater structure B.
It is provided so as to remove deposits existing on the surface of the vertical underwater structure B. The attached matter removing structure 1 is suspended from the float 3 via the suspending tool 6. More specifically, the attachment removing structure 1 is provided with a mounting bracket 4 including a mounting plate 24 and a frame 14 which are connected to the highest-order piece member 11 and the lowest-order piece member 11. The lower end of the hanging member 6 having one end connected to the float 3 is connected to the uppermost mounting member 4, and the attached matter removing structure 1 is hung. As described above, the float 3 serves both as the floating of the attached matter removing structure 1 and the suspension of the attached matter removing structure 1, but a float may be provided completely separately. Symbol WL
Indicates the water surface (sea surface).

A net-like basket 10 is suspended from the lowest mounting bracket 4 via a suspending tool 46. The basket 10 is for collecting the fall-off adhering to the underwater structure B 'extending horizontally or horizontally. In the example shown in FIG. 7, since the suspension is hung on the float 3 connected to the attached matter removing structure 1, the movement of the attached matter removing structure 1 is limited around the underwater structure B which is a vertical pile. . In order to avoid this, the float of the adhering substance removing structure 1 is completely different from the float 3 connected to the adhering substance removing structure 1 as described above. By connecting the floats, the attached matter removing structure 1 can be freely moved along the horizontal or laterally extending underwater structure B ′. Reference numeral 200 shown in FIG. 7 is a weight for preventing the basket 10 from floating.

Since the float 3 moves irregularly up and down, left and right, and back and forth, the float 3 is continuously arranged along the length, and freely rotates around the plurality of link members 11 and the respective link members. One or more rings 5 attached to
Collides with the irregular movement of the float 3 and collides with the underwater structure B 'extending horizontally or laterally, and the attached matter can be effectively removed.

Next, FIGS. 8-10 will be described. This is a buoyancy type adhering matter removing device for removing sea creatures and the like attached to the bottom of a ship. This device includes a support structure 1-1, an attached matter removing structure 1-2, a float 3, a rope 300, a mounting bracket 4, and the like. The support structure 1-1 is two long elongated bodies extending substantially parallel to the bow and stern directions along both sides of the ship B ″, and has a length about the entire length of the ship. 1-2 is an elongated body having one end connected to one of the support structures 1-1 and traversing under a ship hull and connected to the other support structure 1-1 as shown in FIG. Rope 3
00 is a mounting flange 13 integrated with the float 3 as shown in the figure.
To fix the two support structures 1-1 arranged along both sides in a well-balanced manner to the attachments on the deck of the ship B ″, and to the attachments arranged on the side and bottom of the ship. This is for effectively removing the deposits by the removing structure 1-2.The length of the rope 300 is adjusted to change the position of the bottom of the deposit removing structure 1-2. As shown in Fig. 8-10, the support structure 1-1 can be an adhering substance removing structure having the same structure as the adhering substance removing structure 1-2.
The role of supporting both ends of the long-sized deposit removing structure 1-2 and the role itself of removing the deposits on the side of the ship also serve. In the following description, this shared example will be described. The symbol WL indicates a water surface.

The adhering substance removing structure includes a plurality of bridge members 11 arranged continuously, and the bridge members 11 are connected via bolts or pins to form a link mechanism. Since any bolts or pins connected to the bridge member 11 are arranged so as to be parallel to the hull or bottom, the bridge member 11 can be deformed according to the shape of the boat or the shape of the flank or bottom. In response to wind, waves, or tidal forces, the link member 11 that is linked and linked repeatedly impacts the ship's flank hundreds or tens of thousands of times while deforming irregularly. The collision of the piece member 11 due to such irregular deformation brings about an extremely effective removing effect on the attached matter such as marine life. Thereby, the deposit removing structure 1-1 and the deposit removing structure 1-2 effectively remove deposits such as marine life on the ship side and the ship bottom.

The extraneous matter removing structure 1-2 arranged across the hull or under the bottom of the ship repeatedly swings in conjunction with the extraneous matter removing structure 1-1. It is good to arrange an appropriate number. There is no particular limitation on the number of this arrangement. One or more rings 5 mounted for free rotation can be further provided around each piece member 11. This ring 5 is identical to that already described. Although this ring 5 is not shown in FIGS. 8-10, it is the same as that described in FIG. This ring 5 gives a collision that rubs down on the ship's flank or bottom, preventing wear of the ring 5 and, at the same time, adapting to the curved ship's flank or bottom and removing sea creatures and the like very effectively.

FIGS. 11 to 14 show another embodiment of the present invention.
It will be described based on. The buoyancy type adhering matter removing apparatus A of the present invention
Is a first attached matter removing structure 1 'and a first attached matter removing structure comprising a plurality of pieces 11 and, if necessary, a plurality of rings 5 mounted so as to freely rotate around the pieces. A float 3 attached to an appropriate part of the body 1, a mounting bracket 4 for attaching the float to the attached matter removing structure 1, a pulley 7 attached to the float 3, a wire or rope 6 hung on the pulley 7, a weight 200 (reference numeral 6) 7 and 11 have the same function in FIGS. 7 and 11,
And the like.).

As shown in FIGS. 11 and 14, in the present invention, an annular second deposit removing structure 1 'is installed around an underwater structure below the first deposit removing structure 1. This second
The bridge member 11 of the extraneous matter removing structure 1 'may be a one-stage annular body linked with a link, but if two or more stages are used, the removing effect is further enhanced. A float 3 is arranged at an appropriate place around the first attached matter removing structure 1, and a bolt 22 is inserted through a mounting flange 13 below the float 3 and a hole above a pulley 7 as shown in FIG. The float 3 and the pulley 7 are fixed by fixing with a nut (not shown). Further, a weight 200 is attached to one end of the wire or rope 6 hung on the pulley 7. The other end of the wire or rope 6 is fixed to a mounting plate 24 arranged around the second attached matter removing structure 1 '. Thus, it is most effective to attach the pulley 7 to the float 3, but it is also possible to attach the pulley 7 to the second deposit removing structure 1 'as required. The pulley 7 may be attached at any position as long as the weight 200 and the second attached matter removing structure 1 'and the weight of the facilities attached thereto are balanced and endure (can be held in a well-balanced state). The accompanying equipment is, for example, a case where a net for collecting and removing the removed deposits is disposed by being connected to and suspended from the second deposit removal structure 1 '. Such a structure is described in the basic invention by the present inventor (Japanese Patent Application No. Hei 9-164374), and the description is omitted here.

The diameter of the ring-shaped second adhered substance removing structure 1 'disposed around the underwater structure B is set to a diameter substantially close to the diameter of the underwater structure B. Due to the action of the weight connected to one end of the wire or rope 6 hooked on the pulley 7, there is no resistance unless there is any deposit around the underwater structure B. (2) The attached matter removing structure 1 'floats as it is and reaches a position immediately below the first attached matter removing structure 1. However, if there is any extraneous matter, it hinders the floating of the second extraneous matter removing structure 1 ′, and the piece member 1 is moved by the irregular movement of the float 3 due to waves, tides and the like.
1 repeatedly collides with the attached matter several hundred to tens of thousands of times to remove the attached matter of the underwater structure B. When the peripheral removal is completed, it gradually rises along the underwater structure, rises to a position directly below the first attached matter removing structure 1, and the removal of the attached matter is completed.
In FIG. 14, the second attached matter removing structure 1 ′ is arranged at a position slightly distant from the underwater structure B, but this is for easy understanding. Actually, the inner surface of the second attached matter removing structure 1 ′ is arranged so as to be substantially equal to the outer shape of the underwater structure B. This makes it possible to remove the attached matter almost completely. When the ring 5 is fitted to the bridge member 11, a relatively gentle effect of peeling off the adhered substance is achieved, the wear of the ring 5 is reduced, and the bridge member 11 floats up without any damage and the removal is completed. On the other hand, in order to have a rapid removal effect, the ring member
To remove the deposits.

As shown in FIG. 12, at least one pair of the bridge members 11 can be fastened by a spring 8 in order to bring the bridge member 11 into close contact with the underwater structure B to have a more effective collision. Since the pieces 8 are constantly urged by the springs 8 in the contracting direction, the pieces 11 are constantly applied with a force toward the underwater structure B. The springs 8 can be arranged at intervals in a plurality of sets of the bridge members 11. Thereby, the average contraction force in the direction of the underwater structure B increases. Further, as described above, the inner diameter of the second attached matter removing structure 1 'is set to be substantially equal to the outer shape of the underwater structure B. (2) Since the extraneous matter removing structure 1 'can be expanded with some allowance, there is an advantage that such a protrusion does not hinder the levitation. The spring 8 uses the existing equipment,
That is, the bolt 22 and the tongue piece 1 inserted into the piece member 11
Although the connection is made using the insertion hole 11c of 1b, it may be fixed to a fixture other than such a device.

As shown in FIGS. 13 and 14, the piece members 11 of the second attached matter removing structure 1 'can be arranged close to two or more upper and lower stages. Since the piece member 11 is linked, it can move up, down, left and right due to waves or tide, but it is inevitable that a gap is formed at the corner. When two or more stages are provided, it is possible to further enhance the attached matter removing effect.
In this case, if the piece members 11 are arranged so as to be shifted from side to side without being vertically aligned, the blind spot for removing the attached matter is eliminated, and the attached matter can be removed more effectively. FIG. 3 shows the mounting structure. The rod 26 and the wire 6 connected to the plate 26a provided with the hole 26b are crushed by the collar 3
6 are joined. The plate 26 a is fixed to a mounting plate 24 provided on the mounting bracket 4 with bolts 22 and nuts 32. As can be seen from this figure, the frame 14 of the mounting bracket 4 has two upper and lower stages, and the bridge member 11 is inserted into each of them to form the upper and lower two-stage annular second attached matter removing structure 1 '. . By further connecting the frames 14, three or more stages can be provided. Further, a ring 5 which can rotate freely as shown in FIG. 5 can be provided around the bridge member 11 of the first and second adhered substance removing structures 1 and 1 '. The purpose and function of installing the ring 5 in this case are the same as those already described, and thus will not be described here.

The above-described apparatus of the present invention can be used not only for the underwater structure B having a columnar shape but also for a prismatic structure or a structure arranged obliquely. In the case of a prism, a pair of piece members 11 at the corners may be angled to each other, for example, 90 ° and fixed with bolts, and the other piece members 11 may be freely rotatable by a link mechanism. it can. According to the above configuration, the underwater structure B can be moved up and down by the length of the wire or the rope 6 with respect to the underwater structure B. It is possible to remove extraneous matter.

When using the buoyancy type debris removing apparatus A for underwater structures configured as described above, first, the plurality of debris forming the first debris removing structure 1 and the second debris removing structure 1 'are formed. After the tongue pieces 11b are fitted to the tongue piece receiving slots 11a of the adjacent piece members 11,
The bolt 22 is passed through the insertion hole 11 c and fixed with the nut 32. The bolts 22 are rotated so that the piece members 11 can rotate with each other.
And the nut 32 are fixed only at the tip. The piece member 1
When fixing each other so as to maintain a certain angle, the bolts 22 and the nuts 32 need to be tightly fastened so that they cannot rotate. Then, as shown in FIGS. 1 and 6, the float 3 is attached. Further, a pulley 7 is mounted on the mounting flange 13 of the float 3, and a wire or rope 6 is hung on the pulley. A weight 200 is mounted on one end of the wire or rope 6, and a second attached matter removing structure 1 'is mounted on the other end. Board 2
Fix to 4.

As described above, the buoyancy type adhering substance removing apparatus A, in which the bridge members 11 of the first adhering substance removing structure 1 and the second adhering substance removing structure 1 'are connected to each other, is floated on the water surface in the same manner as described above. Workers such as husbands carry to the installation site while dragging,
Then, the tongue piece 11b is fitted into the tongue piece accommodating slots 11a of the piece members 11 at both ends thereof, and then the spring-loaded pin 12 is inserted into the insertion hole 11c. The mounting is completed by hooking a U-shaped spring rod 12b at the tip of 12a.

When the underwater structure B is, for example, a square pillar of a pier or a breakwater, and the buoyancy type adhering material removing device A is to be maintained in that shape, the two pieces 11 corresponding to the corners of the pillar are fixed at right angles. And a square shape can be maintained by tightly tightening the bolts 22 and nuts 32 used therein. As described above, since each piece member 11 is rotatable and relatively angle-adjustable by the link mechanism, the adhering substance removing device A can be connected to the underwater structure B by selecting the number of connected piece members 11. Can be arranged in a manner similar to the shape of.

An adhering substance removing apparatus A comprising the first adhering substance removing structure 1 and the second adhering substance removing structure 1 'arranged as described above receives the force of waves, winds, tides, etc., and applies the same to the underwater structures B. , And at this time, the piece member 11 or the ring 5 which is provided on the outer periphery of the piece member 11 and rotates and moves left and right as necessary comes into contact with the underwater structure B, and is dense with respect to the attached matter. The collision is repeated, and the removing action is performed.
Thereby, even if it is a long underwater structure B, the attached matter removing device of the present invention can effectively remove the attached matter such as shellfish and seaweed.

A more preferable mounting form of the bridge member of the present invention and another member will be described with reference to FIGS. As described above, in the present invention, the ring 5 is rotatably mounted on the bridge member 11 to enhance the adhering matter removing effect, and at the same time, prevent wear of the bridge member 11 and damage to the underwater structure. When the attached matter removing apparatus of the present invention having such a structure is attached to an underwater structure for a long period of time, corrosion is particularly generated in metal fittings against seawater. General-purpose products or equipment with a simple structure (seawater-resistant metal material) can be easily obtained and exchanged, but those with special shapes and structures are specially manufactured for this equipment. There is a need. From the viewpoint of cost, it is necessary to avoid such expensive custom-made products having corrosion resistance. For this reason, in the present invention, as shown in FIG. 15, a part of the plurality of link members 11 linked to each other is replaced with a piece member 11 'having a plate-shaped fin (fin) 8 on the side. It is structured to be connected to other members via the fins 8. As shown in the example of FIG. 15, the seawater-resistant bolt 5 is inserted into the hole of the mounting flange 13 of the float 3 and the hole 8a of the fin 8 and fastened with a nut. The fin 8 is desirably manufactured integrally with the bridge member 11 'from resin such as polyethylene. As described above, the bridge member 11 'provided with the fin portion 8 requires only a slight change of the bridge member 11, and need only be installed at a place where it is connected to other members. The piece member 11 'also has a function of removing extraneous matter, and the ring 5 can be rotatably mounted. The coupling device formed by the fins 8 has excellent features that it is much more resistant to seawater than the metal frame 14 already described, has a simple structure, and requires a small number of coupling equipment.

The piece 11 'with the fin 8 of the present invention can be used over all of the various fittings already described. FIG. 16 shows the horizontal underwater structure B 'of FIG.
This is an example in which the present invention is applied to an attached matter removing device. The uppermost and lowermost piece members 11 of the piece member 11 installed annularly around the horizontal underwater structure B 'are replaced with a piece member 11', and a fin 8 projecting from the piece member 11 'is provided at the uppermost portion. The mounting plate at the lower end of the hanging tool 6 such as a wire or a rope hanging from the float 3 is fixed with a bolt 22 and a nut 32 as shown in FIG. At the lowermost position, the fin 8 protruding from the bridge member 11 'and the hanging tool 46 for suspending the basket 10 are similarly connected using the connecting plate 9 having the C-shaped hole 9a. Since the metal frame 14 is not used, the number of components having a complicated structure and being easily corroded is reduced, and mounting is simplified.

FIG. 17 shows a case in which a part of the ring members 11 arranged in two stages in FIG. 13 is replaced with a member 11 ', and the members 11' are connected to each other by using the connecting plate 9, and at the same time, wires or It is fixed to a mounting plate 26a at the lower end of a hanging tool 6 such as a rope by bolts 22 and nuts 32. With the configuration shown in FIG. 17, a complicated frame-shaped metal fitting (frame body 4) for connecting the two piece members 11 as shown in FIG. 13 becomes unnecessary. Naturally, the piece member 11 'of the present invention is not limited to the example shown in FIGS.
It is applicable to all 14 examples. In addition, as shown in each example of the present invention, metal fittings are of course effective for short-term use within the service life (corrosion resistance) period. In this way, the piece member 11 'itself has the protruding fin 8 serving as a connecting tool, thereby reducing the number of fasteners that are susceptible to corrosion by seawater and making it possible to use the attached matter removing device for a long time. Become.
