On November 8, under the Hangzhou Road overpass, the staff of the street lamp management office lowered the high-pressure sodium lamp of 30 meters high with a remote control, and installed a long metal thorn called "anti-bird thorn" on this headlight.
According to the construction personnel, there are five 30-meter-high streetlight poles around the Hangzhou Road overpass. All of them are imported high-pressure sodium lamps. The power per ton is 1000 watts. The cost is very high, but birds such as magpies often land on them or Making a nest has a great impact on the lifting and wiring of the luminaire. The "bird-proof thorn" is a bird-repelling device, which is made up of steel strands. Because the strands are soft and rigid, they can effectively prevent large birds from standing or making nests above and within the protection range. It will not hurt the bird, it is a very practical "anti-bird suit."
