이는, 타워의 교체 작업으로 인한 발전기의 사용이 중단되는 문제가 있었다.This is a problem that the use of the generator is stopped due to the replacement operation of the tower.

상기 종래기술의 문제점을 해결하기 위해 안출된 본 발명의 목적은 고무판 사이에 금속판을 적층시켜 수직하중에 대한 강성을 보강하는 한편, 상기 고무판과 금속판 사이의 접지면적을 확장시키기 위한 요철부를 형성함으로써, 고무판과 금속판 사이의 접착력이 향상되고 아울러 탄성받침의 탄성계수를 향상시켜 풍력발전기의 타워에서 발생되는 진동을 흡수하는 능력 및 바람에 의해 휨변형 후에 복원하는 능력이 향상되어 타워 구조물의 안전시공에 기여하도록 하는 풍력발전기의 타워설치용 탄성받침을 제공함에 있다.An object of the present invention devised to solve the problems of the prior art by stacking the metal plate between the rubber plate to reinforce the rigidity against the vertical load, while forming the uneven portion for expanding the ground area between the rubber plate and the metal plate, The adhesive force between the rubber plate and the metal plate is improved, and the elastic modulus of the elastic bearing is improved to improve the ability to absorb vibrations generated in the tower of the wind turbine and to restore after bending deformation by wind, contributing to the safety construction of the tower structure.

이하, 본 발명의 바람직한 실시예에 대해 첨부된 도면을 참조하여 자세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

동 도면에서 보는 바와 같은 본 발명은 풍력발전기의 타워 플랜지 결합부에 설치되어 방진역할을 수행하도록 된 탄성받침(120)에 관한 것이다.The present invention as shown in the figure relates to the elastic support 120 is installed in the tower flange coupling portion of the wind power generator to perform the role of vibration.

본 발명의 타워(110) 구조를 설명하면, 원형 강관의 상하측 양끝단에 볼트 체결이 가능하도록 플랜지(111)를 형성하고 있다.Referring to the structure of the tower 110 of the present invention, the flange 111 is formed to be bolted to the upper and lower ends of the circular steel pipe.

상기 타워(110)는 수직방향으로 다수가 연결되어 일정높이 지상으로 연장되는 구조로 이루어져 있다.The tower 110 has a structure in which a plurality is connected in the vertical direction and extends to the ground at a predetermined height.

즉, 플랜지(111)와 플랜지(111)를 맞댄 상태에서 체결볼트(130)를 관통시켜 조립하게 된다.That is, the flange 111 and the flange 111 to pass through the fastening bolt 130 to be assembled.

이때, 상기 결합되는 상하측 플랜지(111)의 사이에는 원주둘레를 따라 다수의 탄성받침(120)을 설치시켜 방진기능을 수행할 수 있도록 한다.At this time, between the upper and lower flanges 111 to be coupled to install a plurality of elastic support 120 along the circumference to perform the dust-proof function.

상기한 탄성받침(120)은 플랜지(111) 둘레에 대략 30~70개 사이로 분할하여 설치하게 된다.The elastic bearing 120 is installed by dividing the flange 111 between about 30 to 70 pieces.

상기 탄성받침(120)의 구성에 대해 보다 자세히 설명하면, 내외면의 곡률이 타워(110)의 플랜지(111) 곡률반경과 일치하는 판상으로 제작되며, 다수의 고무판(121)과 금속판(125)이 교대로 적층되는 구조로 이루어져 있다.In more detail with respect to the configuration of the elastic support 120, the curvature of the inner and outer surface is made of a plate shape that matches the radius of curvature of the flange 111 of the tower 110, a plurality of rubber plate 121 and the metal plate 125 It consists of a structure which is alternately laminated.

이때, 상기 고무판(121)과 금속판(125)의 접지면적을 넓히기 위한 방법으로 금속판(125)의 일면 또는 상하측 양면에 음각부 및 양각부로 이루어진 요철부(127)를 형성한다.At this time, as a method for widening the ground area of the rubber plate 121 and the metal plate 125, the concave-convex portion 127 consisting of an intaglio portion and an embossed portion is formed on one surface or both upper and lower sides of the metal plate 125.

상기 요철부(127)의 음각 및 양각의 형태는 곡선이나 삼각, 사각 파형이 모두 가능하다.The intaglio and embossed shapes of the uneven parts 127 may be curved, triangular, or square waveforms.

상기한 바와 같이 고무판(121)과 금속판(125) 사이의 접지면적을 넓히게 되면, 탄성받침(120)의 탄성계수를 높여 진동흡수 및 복원력을 향상시킬 수 있게 된다.As described above, when the ground area between the rubber plate 121 and the metal plate 125 is widened, the elastic modulus of the elastic support 120 may be increased to improve vibration absorption and restoring force.

여기서, 상기 고무판(121)은 물과 유사하게 포아손비가 0.5에 근접하는 이상적인 비압축성 재질인 관계로 탄성받침의 팽출량은 사용되는 고무판(121)의 강성 및 사용되는 고무판(121) 한층의 두께에 지배적인 영향을 받게 된다.Here, since the rubber plate 121 is an ideal incompressible material having a Poisson's ratio close to 0.5, similar to water, the amount of expansion of the elastic support is dependent on the rigidity of the rubber plate 121 and the thickness of the rubber plate 121 used. You will be dominantly affected.

또한, 외관상의 팽출량은 사용되는 피복고무의 두께에 따라서 상당히 달라지게 된다.In addition, the apparent amount of swelling varies considerably depending on the thickness of the coated rubber used.

포아손비란 압축하중에 대한 압축변형율과 측면방향의 인장변형율과의 비를 말하지만, 포아손비가 0.5란 물리적인 의미는 수직하중에 의한 압축변형량에 해당하는 체적감소와 동일한 부피가 수평방향으로 돌출하는 비압축성 재료라는 것이다.Poisson's ratio refers to the ratio of compressive strain to compressive load and tensile strain in the lateral direction.However, the Poisson's ratio of 0.5 means that a volume equal to the volume reduction corresponding to the compressive strain caused by the vertical load protrudes in the horizontal direction. It is called an incompressible material.

즉, 고무는 압축하중에 의한 압축되는 겉보기 부피와 수평으로 팽창하는 실제 부피가 동일한 포아손비가 0.5인 물체이다. In other words, rubber is an object with a Poisson's ratio of 0.5 equal to the apparent volume compressed by the compressive load and the actual volume expanding horizontally.

이에 비하여 코르크는 수직하중에 의한 압축변형량을 물체 내부의 공극이 흡수하기 때문에 수평돌출량이 전혀없는 포아손비가 0인 물체이며, 콘크리트는 어느 정도는 흡수하고 어느 정도는 돌출하는 포아손비가 0.25정도 되는 물체이다.Cork, on the other hand, is an object with zero porosity ratio with no horizontal protrusion because the void inside the object absorbs the compressive strain due to vertical load. It is an object.

하기 실험예를 통해 탄성받침(120)의 수직탄성계수 및 단면적과의 함수관계에 대해 살펴보면 다음과 같다.Looking at the functional relationship between the vertical elastic modulus and the cross-sectional area of the elastic support 120 through the following experimental example.

수직탄성계수의 계산 (예 : 사각형 135톤)Calculation of vertical modulus of elasticity (e.g. 135 tons square)

받침의 제원: 300mm(단변)×400mm(장변)×105mm(높이), 고무 한층의 두께: 12mm, 철판 한층의 두께: 4mm, 총 고무층수: 6층, 상하 피복두께: 2.5mm, 측면 피복두께: 4mm, 탄성받침의 높이: 12mm×6ea + 4mm×(6+1)ea + 2.5mm×2ea= 105mmSpecifications of the base: 300 mm (short side) × 400 mm (long side) × 105 mm (height), thickness of one rubber layer: 12 mm, thickness of one steel sheet: 4 mm, total number of rubber layers: 6 layers, top and bottom coating thickness: 2.5 mm, side cover thickness : 4mm, height of elastic base: 12mm × 6ea + 4mm × (6 + 1) ea + 2.5mm × 2ea = 105mm

탄성받침(120)의 수직탄성계수 Kv는 하기 [수학식1]에서 보는 바와 같이 고무의 탄성계수(E)와 단면적(A), 그리고 순고무두께(∑te)와의 함수관계에 있으며 다음 [수학식1]으로 평가될 수 있다.The vertical elastic modulus Kv of the elastic support 120 is a function of the elastic modulus of rubber (E), the cross-sectional area (A), and the pure rubber thickness (∑te), as shown in Equation 1 below. Equation 1 can be evaluated.

Kv = E × A / ∑te = 2,962kg/㎠ × (39.2㎝×29.2㎝)/7.2㎝ = 470,989㎏/㎝Kv = E × A / ∑te = 2,962kg / ㎠ × (39.2 cm x 29.2 cm) /7.2 cm = 470,989 kg / cm

여기서, here,

E: (3+6.58S2)×G = (3+6.58×6.972)×9.18 = 2,962㎏/㎠,E: (3 + 6.58S 2 ) × G = (3 + 6.58 × 6.97 2 ) × 9.18 = 2,962 kg / cm 2,

G : 고무의 전단탄성계수 (G=9.18㎏/㎠)G: Shear modulus of rubber (G = 9.18㎏ / ㎠)

S (형상계수) : a×b/[2(a+b)×te] = 29.2×39.2/[2(29.2+39.2)×1.2]= 6.97S (shape coefficient): a × b / [2 (a + b) × te] = 29.2 × 39.2 / [2 (29.2 + 39.2) × 1.2] = 6.97

∑te : 순수고무의 총두께 (상하 피복두께 제외) = 7.2cm∑te: Total thickness of pure rubber (excluding top and bottom cover thickness) = 7.2cm

상기한 바와 같은 구성을 갖는 본 발명에 따른 탄성받침(120)은 고무판(121)과 금속판(125)이 관통되도록 볼트체결공(129)이 형성되고 있어 플랜지(111) 결합시 체결볼트(130)를 관통시켜 결합하게 된다.The elastic support 120 according to the present invention having the configuration as described above is a bolt fastening hole 129 is formed so that the rubber plate 121 and the metal plate 125 penetrates the fastening bolt 130 when the flange 111 is coupled Through to combine.

상기 구성에 따른 본 발명은 고무판(121) 사이에 금속판(125)을 적층시켜 수직하중에 대한 강성을 보강하는 한편, 상기 고무판(121)과 금속판(125) 사이의 접지면적을 확장시키기 위한 요철부(127)를 형성함으로써, 고무판(121)과 금속판(125) 사이의 접착력이 향상되고 아울러 탄성받침(120)의 탄성계수를 향상시켜 풍력발전기의 타워에서 발생되는 진동을 흡수하는 능력 및 바람에 의해 휨변형 후 에 복원하는 능력이 향상되어 타워구조물의 안전한 시공이 가능하게 된다.According to the present invention, the metal plate 125 is laminated between the rubber plates 121 to reinforce the rigidity against the vertical load, and the uneven portion for extending the ground area between the rubber plate 121 and the metal plate 125 is provided. By forming the 127, the adhesive force between the rubber plate 121 and the metal plate 125 is improved, and the elastic modulus of the elastic bearing 120 is improved to absorb the vibration generated in the tower of the wind power generator and by the wind. The ability to recover after flexural deformation is improved, enabling safe construction of tower structures.
