Turbine moving blade trailing edge cooling structure

The invention provides a turbine moving blade tail edge cooling structure, and belongs to the technical field of gas turbine blade cooling, the turbine moving blade tail edge cooling structure specifically comprises a cooling cavity located in a turbine moving blade tail edge, a plurality of column ribs are arranged in the cooling cavity, one side of the cooling cavity is provided with an air inlet channel, and the air inlet channel communicates with an air inlet of a blade root; a plurality of strip-shaped micro-ribs are arranged on the inner wall face, corresponding to the pressure face and/or the suction face of the blade, in the cooling cavity, the strip-shaped micro-ribs protrude out of the inner wall face of the cooling cavity, penetrate through gap areas between the column ribs and are located on the sides, back to the tail edge of the blade, of the column ribs; cold air enters the air inlet channel from the air inlet in the height direction of the blade and then flows out of the trailing edge crack af
