The blade ring is provided with a plurality of water channel groups, which is sequentially arranged at intervals in a circumferential direction of the blade ring. Each of the water channel groups includes two or more inner water channels, which are sequentially arranged at intervals in the circumferential direction of the blade ring, and the width of each of the two or more inner water channels in a radial direction of the blade ring is gradually increased. The cooling structure allows cooling water to cover the entire working surface to improve the cooling efficiency for the working surface and also to effectively improve the utilization efficiency of the cooling water.
