Welding windproof structure

The invention provides a welding windproof structure which is used for door frame welding of a wind power tower drum, belongs to the technical field of wind power generation and comprises a windproof cover, a fixing rod and at least one exhaust part. A containing cavity is formed in the windproof cover, the bottom of the windproof cover is open, notches communicated with the containing cavity are formed in the two opposite sides of the windproof cover, and the notches and the containing cavity jointly form an operation channel, so that when the windproof cover covers the wind power tower which is horizontally placed, the wind power tower is partially located in the operation channel; the fixing rod is arranged in the containing cavity, the fixing rod is used for fixing a safety rope of welding personnel, and the exhaust part is arranged on the windshield to exhaust gas in the containing cavity; therefore, by means of the wind power tower tube door frame welding device, the wind-proof requirement during weldin
