Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating body mooring device in which a main mooring line is attached to a floating body such as an oil fence, a pollution prevention curtain, a fence for separating (preventing diffusion) or mixing of seawater and river water, and the like. is there.

[0002]

2. Description of the Related Art As a conventional oil fence, silt fence, or the like, for example, as shown in FIG.
A rope 102 having a rope 102 fixed at its distal end to an anchor mounting portion 101 provided at regular intervals at 00 and an anchor block 101 attached to a base end portion of the rope 102 is known, and the weight of the anchor block 101 is known. The fence is fixed using.

[0003]

In an oil fence having such a configuration, for example, as shown in FIG. 6, when an external force such as a wave, wind, or tidal current acts, the fence main body 1 is closed.
Under the external force, the 00 and the rope 102 generate a tension that bends into a curved shape or the like toward the downstream side or the leeward side. Therefore, if the strength of the fence main body or the rope is insufficient, or if a strong wave or wind that exceeds the strength of the fence main body or the rope is received, there is a possibility that these may be damaged or cut.

[0004] Under such circumstances, when used in a sea area where sea conditions are severe, it is necessary to consider strength accordingly. In particular, if the fence body is formed of a rubber belt, it is necessary to take measures such as increasing the strength of the reinforcing canvas inserted into the inside or increasing the number of canvases inserted. However,
If such measures are taken, the number of manufacturing steps in the factory may increase, and the manufacturing cost may increase accordingly.

Accordingly, the present invention has been made in view of the above-mentioned drawbacks, and has as its object to provide a floating mooring device capable of preventing occurrence of troubles such as breakage or cutting of a fence body without increasing manufacturing costs and man-hours. It is intended for.

[0006]

That is, according to the present invention, an anchor mounting portion is provided on a hanging type floating body such as a silt fence, an oil fence, a pollution prevention curtain, and a fence for separating or mixing seawater and river water. A floating body mooring device in which an anchor block is submerged and fixed to the sea floor, a lake bottom, a riverbed, or the like via an anchor rope having one end fixed to the anchor mounting portion, and has a long shape with high tensile strength along a length direction of the floating body. Is attached.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings. In this embodiment, the same parts as those of the prior art are denoted by the same reference numerals, and redundant description will be avoided. FIG. 1 shows a floating body mooring device according to the present invention. The floating body mooring device has a floating body film in which belt-shaped portions 11 and 12 are formed above and below a main body portion (usually made of a rubber belt). A structure (hereinafter, referred to as a floating body) 1 is used, and a long tension member 2 which withstands a high tension along a length direction of the floating body 1 is provided on a strip portion 12 of the floating body 1 submerged in water. Is installed. In addition, the code | symbol 13 in the figure shows an anchor attachment part, 3 shows a rope, and 4 shows an anchor block.

The anchor attachment portions 13 are formed at regular intervals on the belt-shaped portion 12 using a material such as a thick canvas or the like. In this embodiment, for example, as shown in FIG. It is attached to the front and back of the belt-shaped portion 12 and is fixed firmly by appropriate means (for example, rivets, eye bolts, eye nuts, etc.). In addition, the anchor mounting portion 13 of this embodiment has an anchor mounting hook 13A so that the rope 3 can be stopped downward and the tension member 2 extending in the left-right direction can be stopped. Rings 2A fixed to both ends of each tension member 2 are attached to the hooks 13A via shackles 13B. The same applies to the rope 3.

The tension member 2 is provided to enhance the strength of the main body 10 and is externally attached to the band-like portion 12 of the floating body. In this embodiment, a wire is used. Any material having a high strength (high tensile resistance) can be used. The tension member 2 is provided between the adjacent anchor attachment portions 13, and the length thereof is equal to or longer than the length of the band (or the main body 10) between the anchor attachment portions 13. A slightly shorter length is used. In addition, as shown in FIG. 3, the tension member 2 is provided with several locking members 14 at appropriate intervals on the belt-shaped portion 12 of the floating body 1 for the purpose of preventing bending for external attachment. For example, in this embodiment, an eyebolt (or eyenut) 14 firmly attached to the strip 12 is used.
Although the tension member 2 is locked via the shackle 15, the invention is not limited to this. For example, an appropriate hook made of a metal that is strong against salt water and strong in strength is used. Is also good. In this embodiment, the tension members 2 are attached to both sides of the belt-shaped body 12, but the invention is not limited to this, and the tension members 2 may be attached to only one side.

Therefore, according to this embodiment, as shown in FIG. 4, when a relatively strong wind or wave is generated and acts on the floating body 1, the surface on which the wind or wave acts greatly curves in a convex shape. Try to stretch. However, in this case, the tension member composed of a small elastic member, that is, the wire first receives the force and prevents the force from directly acting on the floating body 1 or the rope 3, so that the floating body or the rope 3 is large. It is prevented from being damaged or cut by an external force.

[0011]

As described above, according to the present invention, a silt fence, an oil fence, a pollution prevention curtain,
An anchor attachment part is provided on a hanging type floating body such as a fence for separation or mixing of seawater and river water, and an anchor block is submerged on the seabed, lake bottom, riverbed, etc. via an anchor rope with one end fixed to this anchor attachment part. A fixed floating body mooring device with a hard elongated tension member attached along the length of the floating body, so that the main body is somewhat flexible and stretchable like a rubber belt. Even if it is, for example, when the sea conditions are severe or the weather is bad and strong winds and strong waves act on the floating body,
Since the tension member first receives and absorbs the external force, damage or destruction of the floating body can be prevented.

Further, according to the present invention, by fixing the strength of the floating body to a certain specification and appropriately changing the specification of the external tension member, it is possible to form a floating body mooring device having various strengths. If the tension member is formed of high strength, a high strength type floating body mooring device can be easily provided. Moreover, according to the present invention, since the tension member is externally attached to the floating body,
It is economical because it does not cause an increase in man-hours and the manufacturing cost can be reduced accordingly.
