Anti-adverse wind device for downhole ditch

The utility model relates to an anti-adverse wind device for a downhole and provides the anti-adverse-wind device in order to solve the technical problems that the conventional downhole ditch is not provided with the anti-adverse wind device; when adverse wind is exhausted through the downhole ditch, the water quantity in the ditch is increased, tunnels are inundated by the water, and more loss is caused. To solve the problem, the anti-adverse wind device comprises a left board slot and a right board slot which are connected through two blocking bars; a baffle matched with the board slots is arranged between the board slots, and is clamped between the two blocking bars. According to the anti-adverse wind device, the baffle arranged between the board slots can move between the same; when the left board slot and the right board slot are clamped on both sides of the downhole ditch, all that is needed is to pull down the baffle to prevent the water from flowing upwind and prevent the tunnels from being inundated
