Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to underwater structures (for example, steel pipe piles, H-shaped piles, square piles, concrete piles and walls, etc.) for supporting marine structures such as sea berths, artificial islands and piers.
Vertical piles, horizontal materials, diagonal materials, piers, pier legs, embankments, floating piers, pontoons), nuclear power plants, thermal power plants, or water intake channels (intake channels) used for waterways such as industrial cooling water Water pipes (intake pipes), hulls such as hulls and hulls (especially on display vessels at anchor, etc.), marine organisms (shellfish such as oysters, barnacles, mussels, etc.) attached to oil fences or shield fences and the like The present invention relates to an apparatus for removing marine organisms and the like that effectively removes deposits such as entrained or attached sludge.

[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. 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. In a water intake channel or a water intake pipe (mainly 1 to 3 m in diameter), the diameter of the pipe is reduced due to attached marine organisms and the like, and unevenness is formed on the inner surface of the pipe, so that the resistance of the water flow increases. As a result, the water collection capacity drops and the amount of water changes. Furthermore, it is a cause of an increase in the amount of foreign substances mixed in due to marine organisms coming off or dead bodies or sludge entrained in these bodies. 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. The same applies to the removal of deposits attached to the hull and the bottom of the hull, especially for ships. It is the present situation. In addition, marine organisms attached to the drainage channel or drainage pipe cannot be seen from the outside, so they do not notice abnormalities for a long time,
If the diameter is small, it may be difficult for a worker to enter the pipeline for repair and maintenance work. This increases the number of working days and increases costs.

[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. Various methods have been devised, such as adopting a method of suppressing or killing the adhesion of sea creatures, and attaching a pile cover for protecting the underwater structure, but chemicals such as biocontrol agents are not only used by workers but also nearby. Polluting the sea area, causing environmental pollution problems. 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.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has a brush attached around a plurality of plate-shaped or ring-shaped rotating bodies arranged in parallel at intervals. While rotating the rotating body, the tip of the brush collides with or comes into contact with the wall surface of the sea or the surface of the sea surface to remove marine organisms and the like adhering to the wall surface of the structure. In particular, a water intake channel (water intake channel) or a water intake pipe (water intake pipe) The present invention provides an apparatus for removing sea creatures and the like that can most effectively remove sea creatures and the like adhering to the inner surface thereof in a short time. The term "sea creatures" includes not only creatures such as shellfish, seaweeds, and plankton, but also sludge, sand, gravel, and other organic or inorganic substances caught or attached thereto. The term "sea life" includes aquatic life or freshwater life.
A similar problem occurs in an environment where aquatic organisms or fresh seawater organisms adhere, that is, in rivers and lakes and also in fresh seawater in which freshwater and seawater are mixed, but the apparatus of the present invention described in detail below will be applied to all of them. it can. Therefore, the present invention includes these.

The inventor of the present invention has invented a buoyancy-type adhering matter removing apparatus which utilizes a wave force or a tidal force which moves up and down first (Japanese Patent Application No. Hei 9 (1994) -108686).
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. Further, such a buoyancy type debris removal device is further improved to provide a relatively slow and steady debris removal effect, prolong the life of the debris removal structure, and attach the entire surface of the marine organism deposition area. A device capable of removing the kimono more steadily and cleanly so that the kimono remains as little as possible has also been proposed (Japanese Patent Application No. 9-363304).

In general, marine organisms such as shellfish and seaweed often attach and live near the water surface (on the water surface and 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. Moreover, the above-described invention is unmanned and does not require a power source, and thus has an excellent effect that marine organisms are naturally removed. But,
The only disadvantage is that it is not suitable for removing marine organisms and the like attached to the inner surface of a water intake channel or a water intake pipe where natural forces such as wave power, tidal power and wind power do not act. Therefore, forcibly driving the attached matter removing device is absolutely necessary for removing the sea creatures and the like adhering to the inner surface of such a water collecting channel or a collecting pipe. The present invention effectively solves such a problem.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic explanatory diagram of an apparatus 2 for removing marine organisms and the like, showing an example in which a removal apparatus 2 of the present invention is applied to a pipe 1 such as a water intake pipe arranged horizontally. 1A is a cross-sectional view of the removing device 2 as viewed from the front, B is a right side view of a buoyant body and a waterproof housing part described later, and C is a left side view of a buoyant body, a support member, and a pipe or rod part. . Pipes 1 such as water intake pipes
Is filled or flowing with seawater 3 or the like. Two buoyant bodies (tank, float, etc.) 4 made of resin are installed on the left and right in the pipe 1. In this case, the buoyant body 4 is of a torpedo type made of resin and has an elliptical cross section, but may be made of other material than resin, or may have another shape such as a spherical shape. However, the torpedo type as shown in FIG. 1 is the most stable because it is linear in the length direction of the tube 1, almost curved in the radial direction and almost conforms to the inner surface shape of the tube.
A guide rib 4-1 is provided on the upper surface of the buoyant body 4 to facilitate insertion into the pipe 1.

A waterproof housing (tank / tank etc.) 5 is supported by a support member 4-2 at one lower part of the buoyant body 4 (right side in FIG. 1). A driving device 6 such as an electric motor is installed inside the waterproof housing 5. The waterproof container itself may be configured to generate buoyancy. The motor is driven by charging (not shown) or powered by an externally connected device. The driving device 6 is connected to the pipe or rod 7 via a plurality of connecting portions 6-1 and bearings 6-2, and has a structure for driving the pipe or rod 7 to rotate. The rotation speed of the driving device is appropriately selected according to the material of the object to be removed and the state of adhesion of marine organisms. When the object to be removed is a soft or relatively brittle material, if the rotation speed is extremely increased, the object to be removed itself is worn, which is not preferable. Adjust the rotation speed according to the situation.

A waterproof seal 6-3 is attached to a contact portion between the pipe or rod 7 and the waterproof container 5. Waterproof storage 5
When the internal pressure is slightly higher than the surrounding water pressure, the sealing effect is enhanced and the liquid leakage is reduced. The waterproof housing 5 is of a split type for the drive device 6 for inspection or charging, and is fixed to the flange 6-4 so as to be separable from each other. A support member 4-2 is suspended from a lower portion of the other buoyant body 4 (left in FIG. 1), and the support member 4-2 is provided.
The bearing 4-3 is installed at the lower end. The other end of the tube or rod 7 is rotatably supported by the bearing portion 4-3.
The center line of the pipe or rod 7 is just a pipe 1 such as a water intake pipe
The support length of the support member 4-2 that supports the bearing portion 4-3 and the waterproof storage body 5 is adjusted so as to be at the center line.

Since the buoyancy member 4 and / or the waterproof container 5 of the removing device of the present invention are configured so that the gas and / or liquid for adjusting the buoyancy can be inserted and discharged, the removing device of the present invention moves on the water surface or the sea surface. At the time, a gas such as air is put into the buoyant body 4 (a liquid such as water is discharged), and the device is floated and moved in a divided or integrated state. In addition, when moving underwater, the buoyancy body 4 is filled with water to adjust the buoyancy, and the apparatus is similarly divided or integrated, and moves to, for example, a portion of the intake pipe 1 to which marine organisms or the like are attached. . When performing the work of removing extraneous matter such as sea creatures inside the intake pipe 1 (at the time of construction), all the water of the buoyant body 4 is discharged, the buoyancy is increased, and the buoyant body 4 is attached to the upper part of the intake pipe 1, which will be described later. The removal operation is performed by rotating the brush 9. If the buoyancy in this case is weak, the buoyant body 4 and the like may rotate due to the centrifugal force of the rotating body 8 and the brush 9 described later. Therefore, it is necessary to provide a structure capable of generating sufficient buoyancy.

A plurality of plate-shaped or ring-shaped rotating bodies (flights) 8 are arranged around the pipe or rod 7 in parallel with each other and at intervals. When the rotating body 8 is attached to the pipe or the rod 7, for example, the rotating body 8 is formed into two semicircular split molds (divided bodies), and a flange (not shown) is provided at a portion fitted to the pipe or the rod 7. Provided, and can be mechanically removably joined therewith by bolts and nuts. A spacer may be provided between the rotating bodies 8. Alternatively, the rotating body 8 may be formed in a ring shape, and the rotating body 8 to which a brush 9 described later is attached in advance may be sequentially inserted from one end of the pipe or rod 7 via a spacer. As described above, the number, outer diameter, thickness, etc. of the plate-shaped or ring-shaped rotating bodies 8 can be appropriately changed according to the length of the inner wall, the inner diameter, etc. of the pipe 1 for removing marine life and the like. , Can be easily removed or replaced.

A plurality of brushes 9 are provided around the plate-shaped or ring-shaped rotating body 8. 2 and 3 are plan views of the rotating body 8 and the brush 9. The rotating body 8 has a disk shape in the figure, but may have another shape. A space (circular in the figure) 8-1 is provided inside the rotating body 8 to reduce the weight of the rotating body 8 and at the same time improve the strength of the rotating body 8.

2 and 3, four brushes 9 are mounted around the rotating body 8. FIG. If necessary, other numbers may be used, but a balanced number and arrangement are preferable so that no eccentric force acts when the rotating body 8 rotates. The length, diameter, and the like of the brush 9 are appropriately selected and adjusted depending on the material and size (for example, the pipe diameter) of the object to be removed from which marine organisms and the like are removed. The brush 9 may be mechanically fixed using the clip 9-1 or the like so that the brush 9 can be easily replaced. Various materials such as plastics and metal can be used as the material of the brush 9, but a stainless steel brush is most effective in view of abrasion resistance, corrosion resistance, strength, toughness (elasticity), removal efficiency of marine organisms and the like. . At first glance, since there is a gap between the plurality of rotating bodies 8, it seems that the effect of removing sea creatures and the like there is reduced, but when the brush 9 rotates, turbulent water flows,
Since the removing device 2 of the present invention slightly moves up, down, left and right, the sea creature on the inner surface of the pipe 1 including the vicinity of the brush 9 is uniformly removed without affecting the gap.

When the solder is welded to the tip of the brush 9, the abrasion resistance can be further improved, and since the tip of each brush 9 is slightly heavy, a whip-like effect is produced to remove sea creatures and the like. The result was increased efficiency. FIG.
2 shows a state in which the brush 9 slides on the inner surface 1-1 of the tube 1.
The outermost circle (dotted line) is a virtual line 10 of the rotation trajectory of the tip when the brush 9 is rotated as it is (with no load). As the brush 9 rotates, each brush 9 is elastically deformed like a bow along the removal surface indicated by the solid circle in FIG. 3, but the brush 9 becomes stronger and stronger where sea organisms and the like are accumulated. Long contact makes it possible to effectively remove sea creatures and the like using a brush made of stainless steel or the like having rigidity and flexibility.

Next, FIGS. 4 and 5 show an example in which the removing apparatus of the present invention is applied to a submarine structure having a vertical attachment surface for marine organisms or the like. FIG. 4A is a cross-sectional explanatory view of the removing device as viewed from the front, and FIG. 5 is a side view of the removing device. 4B is a top view of the present removal apparatus, FIG. 4C is a right side view of a buoyant body portion described later, and FIG. 4D is a rotating body (rotating body shown in FIGS. FIG. A number of plate-like or ring-like rotating bodies (flights) around the pipe or rod 7
The rotating bodies 8 are provided with a plurality of brushes 9. This structure is exactly the same as the structure shown in FIGS. Therefore, the brush 9 is mechanically fixed to the rotating body 8 so that the brush 9 can be easily replaced using the clip 9-1 or the like. Hereinafter, the description overlapping with FIGS. 1 to 3 will be omitted.

In FIG. 4, the wall surface of the underwater structure to which marine organisms and the like adhere is in the direction opposite to the paper surface. FIG. 5 shows the vertical wall surface 11 of the underwater structure (right next to the brush). 4 and 5, the tube or rod 7 is arranged parallel to the wall 11 and vertically. Therefore, a large number of plate-shaped or ring-shaped rotating bodies (flights) 8 rotate horizontally, and the brushes 9 attached thereto also rotate horizontally.

A buoyant body 12 is provided on the side of the brush 9 arranged in the vertical direction. As will be described later, the brush 9 arranged in the vertical direction is supported by the buoyant body 12. I have. A driving device 13 is provided in each of the buoyant bodies 12, and a rotating rod 15 extending vertically upward is installed above the driving device 13. The rotational driving force of the driving device 13 is transmitted to the rotating rod 15 via the coupling 14. The driving device 13 uses an electric motor or the like, and can adopt a rechargeable or external power supply system. A bearing 16 is provided on an upper frame of the buoyant body 12, and an upper portion of the rotating rod 15 is supported on the bearing 16, and a sprocket 17 is mounted thereon.

A similar sprocket 17 is attached to the upper end of the tube or rod 7 and both sprockets 17 are connected by a chain 18. As a result, the rotational driving force of the driving device 13 is transmitted to the tube or the rod 7 via the rotating rod 15, and a large number of plate-like or ring-like rotating bodies (flights) are provided.
8 and the brush 9 mounted thereon also rotates horizontally. It is desirable to cover these series of rotary drive mechanisms with a safety cover 22. The upper frame of the buoyant body 12 is provided with a slide flange 22-1 into which the safety cover 22 can be slid and inserted. The buoyant body 12 in which the driving device 13 is installed needs to be liquid-tight so that splashes of waves do not enter.

It is preferable that the drive unit 13 be installed as low as possible in the buoyant body 12 to lower the center of gravity and increase the stability. The brush 9 arranged in the vertical direction moves (inclines) in accordance with the movement of the buoyant body 12, so that the buoyant body 12
It is important to maintain stability. As shown in FIG. 4, by connecting to the adjacent brush 9 or buoyant body 12, the degree of inclination of the brush 9 is reduced and the stability is enhanced.

At the lower end of the buoyant body 12, a rod 19 is vertically suspended downward, and a water flow adjusting plate 20 is attached to the rod 19 so as to adjust the angle. A water flow is generated in the vicinity by the rotation of the brush 9, and the water flow adjusting plate 20 receives the water flow and applies a force to press the buoyant body 12 and the brush 9 coupled thereto toward the wall surface 11 of the underwater structure. can do. When the rotating brush 9 is pressed against the wall surface 11 of the underwater structure, marine organisms and the like are effectively removed. A mechanism (not shown) for pressing the rotating brush 9 against the wall surface 11 of the underwater structure if there is a space above the structure
Can be further added.

The minimum unit of the apparatus for removing marine organisms 21 of the present invention comprises one tube or rod 7 to which a number of brushes 9 are attached for one buoyant body 12 described above. According to the size of the wall surface 11 of the underwater structure, the number of connected units can be increased. In addition, marine life removal equipment 2
1 can be moved to a required place for work. When the removing device 21 is moved on the sea surface, air or the like is put into the buoyant body 12 and water is discharged and floated in the same manner as described with reference to FIG. 1 (the device may be assembled or divided). Move up to. At the time of construction, that is, when performing the work of removing marine organisms or the like, the work can be carried out in a floating state, or can be carried out under water to some extent to carry out the work. These can be performed by adjusting the buoyancy by adjusting the insertion and discharge amount of air and water into the buoyant body 12. The pipe or rod 7 to which the brush 9 is attached
May be a divided structure as shown in FIG.
In FIG. 5, it can be divided into three tubes or rods 7 in the longitudinal direction, and reference numeral 23 indicates its connection. The split structure makes it easy to manufacture one assembly and is convenient to carry. Apparatus 2 for removing marine life etc. of the present invention
Numeral 1 repeatedly moves up, down, left and right with the movement of the buoyant body 12, and comes into contact with the wall surface 11 of the underwater structure. Therefore, the marine creatures removal device 21 may be operated by ebb and flow of the tide or vertical movement of waves.
Also performs a similar movement. As a result, the wall surface 11 of the underwater structure
Marine organisms and the like can be forcibly removed within a short time over a wide range of upper and lower surfaces. Further, when the brush 9 rotates, a turbulent water flow occurs, and the removing device 2 of the present invention slightly moves up, down, left, and right, so that the wide surface of the wall 11 including the vicinity of the brush 9 is not affected without affecting the gap between the rotating bodies 8. Sea creatures are uniformly removed.

As described above, the pipe or rod 7 of the apparatus for removing marine organisms 21 installed in the vertical (vertical) direction shown in FIGS. Since the flight 8 and the brush 9 attached to the rotating body 8 have the same structure as those of the apparatus 2 for removing marine organisms shown in FIGS. 1 to 3, it can be easily understood that they can be used for both. That is, the simple structure of the removal apparatus for marine organisms and the like according to the present invention can be used for various purposes, from the removal of marine organisms and the like to vertically disposed marine structures from inside a tubular body such as a horizontally disposed water intake channel or a water pipe. Applicable to form. In the case where the width of the underwater structure is relatively narrow and there is a space above the underwater structure such as an oil fence, the brush 9 is arranged on both sides so as to sandwich or straddle the underwater or sea surface structure. As a result, marine life and the like on both sides of the structure can be simultaneously removed.
