Description

[0001] SPRING BUFFER DEVICE [0002]

The present invention relates to a shock absorbing device for relieving an impact caused by a sea current such as a difference in a tide interval or waves due to an ocean or an ocean structure, and more particularly, And an elastic member provided between the first main body and the second main body. When an impact is generated by the current, the elastic member is compressed and then restored by the elastic restoring force, so that the elastic member is excessively stretched And it is also possible to expect a buffering effect stably against an impact caused by an irregular wave.

Marine forests, ie, sea forests, provide oxygen to marine water, purify the marine environment, provide the spawning grounds of various fish and shellfishes, and castle shrubs, which are important functions as primary producers of marine ecosystems.

In recent years, however, perennial seaweed communities such as seaweed, kelp, kelp, mulberry and mulberry have been destroyed due to high water temperature, low salinity, marine pollution, excessive diet of breakfast animals, The damage area is rapidly spreading. In addition, deterioration of seashells due to excessive coastline development, harbor construction, leisure activities, and underwater viewing are intensifying.

In the sea area where the rust phenomenon (ie, whitening phenomenon) occurs, not only depletion of fisheries resources but also eutrophication is promoted, and it is known that natural healing is almost impossible without artificially restoring it.

For this reason, techniques for artificially restoring and restoring the sea forest have been studied. The inventor of the present invention has also been devised by devising various techniques in the past. In this regard, in the related patent application No. 10-1080239 (Oct. 31, 2011) &Quot; Method for preparing a sea forest using the seaweed diatomite and the seaweed diatomaceous earth ", Registered Patent No. 10-1213463 (2012.12.12) " Apparatus for enhancing spore protection enhanced sea forest ", Registered Patent No. 10-1161782 ) And "spore implantation device for sea forest formation".

As a method for constructing the sea forest, there is a method of sprinkling seed (spore of conception concept) in the sea forest and germinating and growing to become an adult and to form a sea forest and a method of transplanting an adult body In some cases, the latter may be preferred in terms of workability and effectiveness.

In addition, in order to transplant such an adult, an adult can be implanted in the graft provided with a graft for adult transplantation as in No. 10-1080239, and the graft can be transferred to the sea to form a sea forest, 10-1213463 or 10-1161782, it is possible to construct a sea forest by transplanting the adult body by fixing the adult body to the existing rope, instead of separately providing an implantable body for adult transplantation. Of course, the latter is preferable in terms of workability and effects.

Particularly, in Japanese Patent No. 10-1213463, when a strong load is instantaneously applied to the spore line by an external force, a cutting member for cutting only the spore line caught by the load is provided, and a part common to the object of the present invention described below is recognized do.

However, in the cutting member disclosed in Japanese Patent No. 10-1213463 and the structure in which such a cutting member is installed on the rope, there is a limit in that a plurality of cutting members must be installed in order to cut only a part of the cutting member. 10-1521630 " Spore Line Assembly for Seed Bank ".

In the above conventional techniques, the float, the buoy, or each of the seabed components are provided with an elastic body made of a spring so as not to be influenced by the current.

That is, in order to prevent an external force due to currents, waves, and the like from directly transmitting impacts to the wires and the respective structures, they are connected through a spring to absorb shock.

However, when connecting both ends of a spring to a wire, a wire, or a structure, if the wave is strong, the force of the current increases and the spring may be stretched and cut off, and irregular forces may be repeatedly applied The tensile force of the spring may be weakened due to the load, and the buffering effect may be deteriorated.

The purpose is to provide.

The first main body is provided with a pillar member passing through a through hole provided in the second main body, and the second main body is provided with a guide member penetrating a through hole provided in the first main body, And to provide a shock absorber capable of linear motion during tension.

It is another object of the present invention to provide a shock absorber capable of allowing a current to flow through a first flow path in the sea due to the formation of a first flow path communicating with the outside.

In order to achieve the above object, a shock absorber according to the present invention comprises:

A first body including a first disk to which a first wire is coupled at one end, a second disk spaced apart from the first disk and having a through hole, and a pillar member connecting the first disk and the second disk to each other;

A third disk disposed between the first disk and the second disk, the second disk being spaced apart from the third disk and positioned above the second disk, and a second wire coupled to the other disk; And a guide member connecting the third disc and the fourth disc and passing through the through hole;

An elastic member provided on the outer surface of the column member and having both ends thereof in close contact with the second disk and the third disk to be positioned between the second disk and the third disk;

And a control unit.

As described above, in the shock absorber according to the present invention,

A second body coupled to the first body and coupled to the second wire at the other end, and an elastic member provided between the first body and the second body to provide an elastic force, So that the elastic member is compressed when a current such as a wave is generated and can be returned to its original position due to the restoring force of the elastic member, thereby solving the problem that the elastic member, which has been a problem in the past, is stretched or broken by the current, It is possible to secure the stability.

In addition, since the first body and the second body are provided with the through-holes through which the pillar members and the pillar members penetrate, the through holes, and the guide members penetrating through the through holes, the elastic bodies are compressed and stretched only in the linear direction So that it is possible to operate more stably.

Further, since both ends of the elastic member are in close contact with the second and third discs, and as the third disc moves between the first and second discs, the distance by which the elastic member can be maximally extended is limited, And the elastic restoring force is lowered.

Further, the distance between the first disk 11 and the second disk 12 can be changed variously according to the elasticity of the elastic member 30 described later.

A pillar member 14 is provided between the first and second disks 11 and 12 to connect the pillar member 14 to the first disk 11 and the second disk 12, 12 and the center of the columnar member 14 are connected to each other. The columnar member 14 is provided to surround the outer surface of the elastic member 30, and is preferably cylindrical.

The second body 20 is provided with a third disk 21 and a second disk 21 so as to be similar to the first disk 11 and the second disk 12 of the first body 10, A fourth disk 22 spaced apart from the third disk 21 and a guide member 24 connecting the third disk 21 and the fourth disk 22 to each other.

A second coupling hole 223 is formed at the other end of the fourth disk 22 so that a second wire bracket 225 to which the second wire W2 is coupled can be fastened like the first disk 11, The second coupling portion 221 is formed.

The third disk 21 and the fourth disk 22 are connected to each other by a guide member 24. The guide member 24 includes a plurality of third disks 21 and fourth disks 22, And a plurality of four pillar members 14 are provided in a balanced manner as shown in the figure.

In this case, when the first body 10 and the second body 20 are coupled to each other, the plurality of guide members 24 And the column member 14 is located inside the columnar members.
