풍차식 조류방지기 취부장치{Adhesion apparatus for a windmill birds prevention tools}Adaptation apparatus for a windmill birds prevention tools

본 발명은 취부장치에 관한 것으로 특히, 기기장치가 설치된 전주나 기타 장주상태가 복잡한 전주에 많은 조류의 활동으로 인한 정전사고를 예방하기 위해 설치하는 조류방지기 등을 작업자가 안전하게 설치 및 제거할 수 있도록 하는 풍차식 조류방지기 취부장치에 관한 것이다.The present invention relates to a mounting apparatus, in particular, a worker to install and remove a bird protector, such as to prevent a power outage caused by the activity of a lot of birds in the electric pole or other state of the state where the device device is installed so that the worker can safely install and remove It relates to a windmill type bird arrester mounting apparatus.

일반적으로 전주에 조류들이 둥지를 만들고 있어서 이로 인한 단전사고가 빈번히 발생하며 이를 철거하는 데에도 작업자가 특고압 전력설비와의 접촉으로 인한 안전사고가 빈번하게 발생된다.In general, birds are making nests in Jeonju, which causes frequent blackout accidents, and safety accidents are frequently caused by workers coming into contact with special high-voltage power facilities.

풍차식 조류방지기는 단전사고 등의 원인이 되는 조류가 접근하는 것을 방지하기 위한 장비로 회전을 하여 조류가 전력설비가 설치된 전주 등에 서식하는 것을 차단하는 장비이다.Windmill type bird preventer is a device that prevents algae from inhabiting electric poles installed with electric power facilities by rotating it to prevent the access of algae which causes the power failure.

종래에는 풍차식 조류방지기를 설치 및 철거하기 위해서는 작업자가 직접 전주에 승주하여 특고압 전력설비(22.9KV)에 접근하여 작업하거나 또는 활선바켓 트럭에 탑승하여 특고압 전력설비에 풍차식 조류방지기를 설치 및 제거하여야 하므로 작업자의 부주의 또는 설비의 노후 기타의 이유로 실수하여 특고압 전력설비에 접촉하였을 경우 감전사고가 발생되며 이로 인한 시공상의 불편이 커서 작업에 어려움이 많다.Conventionally, in order to install and dismantle a windmill type bird preventer, a worker rides in Jeonju to approach a special high voltage power facility (22.9KV), or boards a live basket truck and installs a windmill type bird protector at an extra high voltage power facility. And because it has to be removed, if you accidentally touch the extra-high voltage power equipment due to the negligence of the operator or the aging of the equipment, electric shock accidents occur, which is difficult to work due to the inconvenience of construction.

또한, 특고압 전력설비에 작업자가 감전될 경우 전기적 쇼크로 인한 인사사고를 유발하기도 하며 이를 예방하는 대책이 시급한 문제점이다.In addition, when a worker is electric shock to the special high-voltage power equipment may cause personnel accidents due to electrical shock and measures to prevent this is an urgent problem.

본 발명은 상술한 바와 같은 문제점을 해결하기 위하여 안출된 것으로, 지상이나 활선 바켓트럭에 승차시에도 활선COS(Cut Out Switch) 조작봉과 풍차식 조류방지기를 취부장치를 사용하여 설치 또는 제거할 수 있도록 하여 작업자가 특고압 전력설비 접근을 원천봉쇄하여 안전을 확보하고, 현장의 여건에 따라 다양한 형태의 장주 구성에서 작업자의 편리 및 작업시간 감축을 위해 취부장비를 상부 및 측면에도 취부가 가능하도록 하여 복잡한 장주 취부 및 철거시 작업소요 시간이 획기적으로 감소하고 작업자의 안전사고 예방에 그 목적이 있다.The present invention has been made in order to solve the problems described above, so that even when riding on a ground or live basket truck truck can be installed or removed using a live COS (Cut Out Switch) operating rod and windmill type bird preventer By blocking the access of extra-high voltage power equipment, the operator secures safety, and it is possible to attach the mounting equipment to the upper and side surfaces to reduce the working time and convenience of workers in various types of constructions according to the site conditions. Its purpose is to drastically reduce the time required for installation and removal of the jangju and to prevent workers' safety accidents.
