[Problems to be solved by the invention]

 It has been empirically known that the growth of kelp and the like is favored by metal traces and attached rocks such as metal fine powder, but hard iron chains cannot easily make metal traces. Then, although it was possible to control the growing algae, it was not enough to create a submarine environment for growth. At kelp fishing grounds, etc., calcareous algae called shore-burning are hard-growing on the rock surface, and conventional chains alone are lightweight and have low impact and are difficult to exterminate. There was a problem.

[0005] The present invention has been made in view of the above-mentioned problems, and eliminates marine algae such as Honda straw, lime algae covering a rock surface with a hard calcareous layer, etc., and also attaches zoospores, which are embryos of kelp. The purpose of the present invention is to provide an undersea curing iron weight capable of curing kelp by cultivating and breeding rocky reefs that are easy to grow.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the seafloor curing iron weight according to the present invention is composed of an iron weight body made of a soft iron material having a plurality of protrusions formed on an outer periphery thereof, and a metal chain provided on the iron weight body for a seaweed control device. A free end or an intermediate portion and / or a connecting portion connected to an adjacent iron weight main body.

[0007] The connecting portion connects the iron weight main bodies so that the iron weight main body rotates together with an adjacent iron weight main body.

The connection portion is a connection hole vertically penetrating the iron weight main body.

With the above configuration, the iron weight for seabed curing of the present invention is mounted on a plurality of metal chains of the apparatus for controlling seaweeds, and is slid forward, backward, left and right with respect to the seabed, so that the seafloor swelling on the seabed is reduced. It can remove seaweed by entanglement and peel off or crush the hard-growing lime algae on the rock surface in contact with the seabed rock.

[0010] The iron weight for seabed curing is horizontally mounted on a metal chain and slid, so that the friction that abuts on the seabed repeatedly stores or releases the rotational force and swings repeatedly. By such behavior, the rock surface can be dispersed in such a way that metal components such as metal traces and metal fines are applied to the rock surface. You can measure kelp propagation.

[0011]

[Embodiment of the invention]

 (First Embodiment) Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1 to FIG. 3, the iron weight 3 for seabed curing includes an iron weight body 5 made of a soft iron material having a plurality of protrusions formed on an outer periphery thereof, and a seaweed control apparatus provided on the iron weight body 5. The device has a connecting portion 6 connected to the free end or intermediate portion of the metal chain 2 and / or the adjacent iron weight main body 5.

The iron weight main body 5 is formed of a soft iron material in a spindle shape, and has a projection 31 projecting radially at an angle of 45 degrees from the outer peripheral surface thereof. In this embodiment, the projection 31 has a trapezoidal cross section with a flat top 32 and is formed of eight ridges continuous in the longitudinal direction, thereby forming a so-called gear-shaped cross section. As a result, when it comes into contact with the reef on the seabed, it rotates to flip with unevenness, crushes hard lime such as lime algae, and makes metal traces of soft iron components on the rock surface. By this movement, the soft iron component is dispersed on the sea floor.

The connecting portion 6 includes a locking portion 30 extending from both ends of the iron weight main body 5 to regulate a rotation angle and a connecting hole 34. The locking portion 30 has a caulking surface 33 whose upper surface and lower surface are flattened. The caulking surface 33 rotates together with the adjacent seabed curing iron weight 3 when connecting a plurality of the seabed curing iron weights 3 horizontally. The connection hole 34 is formed so as to penetrate above and below the caulking surface 33, and can be connected to the metal chain 2 for suspending the seabed curing iron weight 3 by a shackle or the like.

In the embodiment shown in FIG. 4, a suspension unit 1, four metal chains 2, and three iron weights 3 for seabed curing are arranged horizontally from the free end to the middle of the metal chain 2. The two ends are connected to two adjacent metal chains 2 and connected by a metal chain connecting member 21. At this time, the adjacent seabed cured iron weights 3, 3 are connected by the connecting pipe 22. In this way, by connecting the seafloor curing iron weights 3 in a plurality of stages horizontally, a wide range of the seafloor can be slid horizontally at a time.

A description will be given of the movement of the undersea curing iron weight 3 suspended in the metal chain 2 by connecting a plurality of them so as to co-rotate horizontally. When sliding, the submarine curing iron weight 3 first rotates forward due to the friction that abuts on the seabed, so that the metal chain 2 rolls backward, but the dragging force eventually exceeds the frictional force and the traveling direction. And the projection 31 returns so as to cut the seabed. In this way, the seabed oscillates while repeating the rotation in the traveling direction and the reverse rotation.

As shown in FIG. 5, the suspension unit 1 is made of steel and has a rectangular T-shaped upper surface. The suspension unit 1 is provided with a working device connecting portion 11 at a central portion in the longitudinal direction, and four hooks 12 are protruded from the lower surface of the suspending portion 1 in the longitudinal direction at a lower side to connect the metal chain 2. I have.

The suspension of another embodiment shown in FIG. 6 has a rectangular T-shape on the upper surface, and is formed in a cross shape that is orthogonal at the center. In addition, a working device connecting portion 11 is provided at one central portion in the longitudinal direction, and eight hooks 12 for connecting the metal chain 2 in the longitudinal direction are protruded from each lower surface at a distance from each other. . By using this suspension, the area that slides on the sea floor is increased, and work efficiency can be further improved.

As shown in FIG. 7, when the suspension unit 1 is attached to the apparatus for controlling seaweeds, an attachment 15 rotatably attached to an arm 13 and a link 14 of a working device such as a hydraulic shovel, The working device connecting portion 11 is connected by the pin 16. Thereby, the arm 13 of the working device such as the hydraulic excavator of the apparatus for controlling algae is moved up and down according to the depth of the seabed. Further, even at the same depth, the metal chain 2 sliding on the seabed and the iron weight 3 for seabed curing can be slid evenly according to the topography by changing the front and rear angles according to the inclination of the seabed.

The metal chain 2 is made of metal and is stiff and heavy, and is slid so as to catch and catch the miscellaneous seaweed rooted on the seabed.

(Second Embodiment) FIGS. 8 to 10 show a submarine curing iron weight 3A according to a second embodiment. The iron weight for seabed curing 3A is composed of an iron weight main body 5A made of a soft iron material having a plurality of projections formed on the outer periphery, and a free end or an intermediate portion of the metal chain 2 of the seaweed control device provided on the iron weight main body 5A. And / or a connecting portion 6A connected to the adjacent iron weight main body 5A.

The iron weight body 5A is formed of a soft iron material in the shape of a flat swelling drum, and has four projections 31 projecting from upper and lower surfaces thereof, respectively. The projection 31 has a trapezoidal cross section with a flat top, and forms a ridge continuous in the longitudinal direction. Further, a first projection is provided on the inner side from both ends of the iron weight main body 5A, and a second projection is provided inside and parallel to and separated from the first projection. At the central portion of the iron weight main body 5A where no projection is provided, a connection hole 34 is formed, which penetrates vertically one by one on the left and right.

The connection hole 34 having a diameter of 25 mm or more can be freely connected by a shackle (not shown) used for chain connection. From this, it can be easily attached to a chain such as an apparatus for controlling submarine seaweeds according to the prior art, and can be dispersed so as to apply metal components such as metal traces and metal fine powder of the iron weight 3A for submarine curing. . In addition, by making the dimensions approximately 20 cm square and 10 cm thick, the weight becomes 15 kilograms or more, so that a strong impact can be exhibited and hard ash such as lime algae on the seabed can be crushed. .

Next, the procedure of the seabed curing operation will be described. As shown in FIG. 11, at the time of work, a hydraulic excavator B is mounted on the deck of a workboat A and moves to a work site.

At the start of the work, first, the arm of the hydraulic shovel is lowered according to the depth of the seabed, and as shown in FIG. 12, the iron weight for seabed curing 3 is suspended so as to scrape the seabed, and the arm 13 is moved back and forth and right and left. Work by doing.

[0026]

[Effect of the invention]

 As described in detail above, the present invention can be manufactured at a low cost because it is composed of simple members, and does not require a maintenance work because there is no failure.

In addition, since a plurality of metal chains are separately mounted, a wide range can be slid. In addition, since multiple stages of seabed curing iron weights are dragged, there are many opportunities to scrape off seaweed that inhibits the growth of kelp that is in close contact with the rock surface, such as lime algae, improving work efficiency and improving the efficiency of seabed reefs. The cleaning situation is also good.

In addition, the projection having a gear-shaped cross section provided on the iron weight for submarine curing abuts on a rocky reef or slag on the seabed, and oscillates by storing rotational force due to friction. Therefore, the sprinkling of spores, kelp, is promoted by dispersing metal components on the rock surface to promote the formation of zoospores, which are embryos of kelp.

Further, according to the iron weight for submarine curing according to the third aspect, the same effect as described above can be obtained by attaching the apparatus to any apparatus for controlling seaweeds of a type in which a chain is suspended.
