Fixed streamline blowing unit structure

The utility model discloses a fixed type streamline air blowing unit structure which comprises an air blowing unit. The air blowing unit structure is fixed to one side of the upstream face of the gate through the fixing support. A plurality of air holes are uniformly distributed in the surface of the air blowing unit, the air blowing unit is communicated with the air supply pipeline so as to receive compressed air provided by external air source equipment through the air supply pipeline, and the compressed air is discharged underwater through the air blowing unit; the air blowing unit is configured to be of a streamline structure with the section size gradually changing, and the axis direction of the air blowing unit is consistent with the water flow direction. According to the air blowing unit structure, the streamline air blowing unit is adopted to relieve the impact of the upstream face, the air blowing unit structure is fixed to the upstream face of the gate through the fixing support, so that bubbles are
