The embodiment of the invention provides a protection device. The protection device comprises an air inlet part and a rectifying part, wherein the rectifying part is arranged below the air inlet partand is opposite to the air inlet part; the rectifying part is provided with an arc-shaped part and a vertical part; the arc-shaped part extends from the top curve of the rectifying part to the vertical part; the vertical part extends upwards from the bottom of the rectifying part to the arc-shaped part, and at least one part of the inner surface of the air inlet part from the bottom is opposite tothe outer surface of the vertical part of the rectifying part so as to form a gap between the two. By utilizing the scheme of the embodiment of the invention, the air wall is formed by utilizing thehigh-speed air flow which is vertically emitted downwards, so that the formed protection air wall can be close to the surface of the protected object and provides an almost consistent protection effect from the top to the botto
