Backflow prevention safety cover for manhole
The present invention relates to a backflow prevention safety cover for a manhole and, more specifically, to a backflow prevention safety cover which is fastened to a manhole frame formed with a protrusion and a support protrusion disposed on the upper side of the protrusion to prevent sewage from flowing backward. The backflow prevention safety cover comprises: a safety cover body formed with a fixed hook panel formed to hook onto the protrusion of the manhole frame; and an operation support part provided on the safety cover body. The structure of the safety cover fastened to the manhole frame to buffer the backflow of sewage is simplified, and a separate fixing device to fix the safety cover to the manhole frame is unnecessary, thereby reducing installation and manufacturing costs. In addition, the time and cost for maintenance can be reduced, thereby facilitating connection and disconnection.
본 발명은 맨홀용 역류방지 안전커버에 관한 것으로서, 보다 상세하게는 걸림턱과 상기 걸림턱의 상측에 배치되는 지지턱이 형성된 맨홀틀에 체결되어 하수가 역류되는 것을 방지하도록 된 역류방지 안전커버로서, 상기 맨홀틀의 걸림턱에 걸림되도록 고정걸림패널이 형성된 안전커버본체와, 상기 안전커버본체에 마련되는 작동지지부로 이루어져, 하수가 역류되는 것을 완충시키도록 맨홀틀에 체결되는 안전커버의 구조를 단순화시키고, 맨홀틀에 고정시키는 별도의 고정장치가 불필요하여, 설치 및 제조비용이 절감되고, 유지보수에 따른 시간과 비용을 줄일 수 있게 되며, 체결 및 분리가 용이한 효과가 있다.
