이하, 본 발명에 의한 납축전지의 양극 음극화 보호 및 그리드 부식 방지를 위한 음극화 보호장치의 실시예를 통해 상세히 설명하도록 한다.Hereinafter, it will be described in detail through an embodiment of a cathodic protection device for anodic cathodic protection and grid corrosion protection of a lead acid battery according to the present invention.

도 2는 본 발명의 실시예에 따른 납축전지의 양극 음극화 보호 및 그리드 부식 방지를 위한 음극화 보호장치를 나타낸 구성도이다.2 is a block diagram showing a cathodic protection device for anodic cathodic protection and grid corrosion protection of a lead acid battery according to an embodiment of the present invention.

도 3은 본 발명의 실시예에 따른 납축전지의 양극 음극화 보호 및 그리드 부식 방지를 위한 음극화 보호장치가 양극판스트랩(200)에 장착되는 예시도이다.3 is an exemplary view in which a cathode protection device for anode cathodic protection and grid corrosion protection of a lead acid battery according to an embodiment of the present invention is mounted on a cathode plate strap 200.

도 2 내지 도 3에 도시한 바와 같이, 상기 음극화 보호장치(100)는,2 to 3, the cathodic protection device 100,

양극판스트랩(200)에 장착되어 양극 그리드의 부식과 양극판스트랩의 부식을 방지하는 것을 특징으로 한다.It is mounted on the anode plate strap 200 to prevent corrosion of the anode grid and corrosion of the anode plate strap.

구체적으로, 납축전지에는 양극판군(50)의 러그(55)들을 잡아주는 양극판스트랩(200)이 존재하게 되는데, 상기 양극판스트랩(200)의 양측면에 장착 즉, 접촉되어 양극 그리드의 부식과 양극판스트랩의 부식을 방지하게 되는 것이다.Specifically, in the lead acid battery, there is a positive electrode plate strap 200 for holding the lugs 55 of the positive electrode plate group 50, which are mounted on both sides of the positive electrode plate strap 200, that is, contact with corrosion of the positive electrode grid and positive electrode plate strap This will prevent corrosion.

특히, 양극 그리드의 부식은 납축전지 배터리의 수명 종지의 한가지 원인이다. In particular, corrosion of the anode grid is one cause of the end of life of the lead acid battery.

따라서, 부식성이 개선될 경우에는 고온 내구성의 향상을 기대할 수 있게 ㄷ되는 것이다.Therefore, when the corrosion resistance is improved, it is possible to expect improvement of high temperature durability.

이때, 부식을 방지하기 위한 여러 가지 방법 중 음극화 보호라는 방법이 있는데, 이는 보호하고자 하는 금속보다 반응성이 뛰어나 대신 산화시키는 방법이다.At this time, among the various methods for preventing corrosion, there is a method called cathodic protection, which is superior to the metal to be protected and is oxidized instead.

이는 선박의 경우에 바닷물 속에서 움직여야 하기 때문에 갈바닉 부식에 항시 노출되어 있으므로 선박 바닥면과 프로펠러의 부식을 방지하기 위하여 인위적으로 아연 메탈을 선박에 부착시켜 아연만 소모되게 하여 강의 부식을 방지하게 되는 것이다.This is to prevent corrosion of the steel by artificially attaching zinc metal to the ship to prevent corrosion of the ship's bottom and propellers to prevent corrosion of the ship's bottom and propellers, since it must be moved in sea water in the case of ships. .

이때, 아연 이외에도 반응성이 큰 알루미늄 재질, 마그네슘 재질을 사용할 수도 있다.At this time, in addition to zinc, a highly reactive aluminum material or a magnesium material may be used.

따라서, 상기한 선박의 갈바닉 부식 방지 대책에 착안하여 본 발명의 배경 기술인 납축전지에도 상기한 부식 방지 대책을 도입한 것이다.Accordingly, the above-mentioned corrosion prevention measures are also introduced into the lead acid battery, which is the background technology of the present invention, in view of the above-mentioned measures to prevent galvanic corrosion of ships.

또한, 납축전지에 적용을 하기 위해선 Pb보다 반응성이 뛰어나고, 그 경쟁력을 잃지 않기 위해선 가격적인 측면도 고려되어야 한다.In addition, in order to apply to a lead acid battery, it is more reactive than Pb, and in order to not lose its competitiveness, the price aspect should also be considered.

따라서, 본 발명에서는 알루미늄 재질의 부식방지 양극 극판군 스트랍에 닿게 하여 극판 및 스트랍의 부식을 방지할 수 있도록 하고 있다.Therefore, in the present invention, it is possible to prevent corrosion of the electrode plate and the strap by making it contact with the corrosion-resistant anode plate group strap made of aluminum.

구체적으로 음극화 보호장치(100)를 양극판스트랩에 장착시키기 위하여,Specifically, in order to mount the cathodic protection device 100 on the anode plate strap,

상기 음극화 보호장치(100)는,The cathodic protection device 100,

집게 구조를 가지고 있으며, 양극판스트랩과 동일한 재질로 형성되는 것을 특징으로 한다.It has a tongs structure and is characterized by being formed of the same material as the anode plate strap.

도 3에 도시한 바와 같이, 상기 집게에 의해 양극판스트랩의 양측면에 접촉되는 것을 특징으로 한다.As shown in Figure 3, it characterized in that it is in contact with both sides of the positive electrode plate strap by the forceps.

이때, 상기 집게 형상은 'ㄷ'자 형상을 가지도록 형성하게 되는데, 'ㄷ'자 형상에 의해 'ㄷ'자 홈이 형성되게 되고, 상기 'ㄷ'자 홈을 상기 양극판스트랩의 양측면에 접촉시키게 되는 것이다.At this time, the tongs shape is formed to have an 'U' shape, and an 'U' groove is formed by the 'U' shape, and the 'U' grooves are brought into contact with both sides of the anode plate strap. Will be.

또한, 상기 음극화 보호장치(100)는,In addition, the cathodic protection device 100,

집게 구조를 가지고 있으며, 양극판스트랩과 동일한 재질로 형성되는 것을 특징으로 한다.It has a tongs structure and is characterized by being formed of the same material as the anode plate strap.

예를 들어, 양극판스트랩이 부식을 방지하기 위하여 알루미늄 재질로 형성하게 되면, 상기 음극화 보호장치(100)의,For example, when the cathode plate strap is formed of aluminum to prevent corrosion, the cathode protection device 100,

재질은 알루미늄 재질인 것을 특징으로 하는 것이다.The material is characterized by being an aluminum material.

즉, 납보다는 부식성이 뛰어난 알루미늄 재질을 이용함으로써, 선박의 갈바닉 부식 방지 대책과 유사하게 부식을 방지하게 되는 것이다.That is, by using an aluminum material having superior corrosion resistance to lead, corrosion is prevented similarly to the anti-galvanic corrosion protection of ships.

따라서, 납축전지의 수명 종지 원인 중에 하나인 양극 그리드의 부식을 방지하여 고온 내구성을 향상시키며, 납축전지의 양극 음극화를 방지할 수 있게 된다.Therefore, it is possible to prevent the corrosion of the anode grid, which is one of the causes of the end of the life of the lead acid battery, to improve the high temperature durability, and to prevent the anode cathode of the lead acid battery.

즉, 양극판군의 음극화를 보호하면서 그리드 부식을 방지할 수 있으므로 방전량 및 수명을 향상시키는 상승 효과를 제공하게 되는 것이다.That is, it is possible to prevent the grid corrosion while protecting the cathode of the positive electrode plate group, thereby providing a synergistic effect of improving the discharge amount and life.
