Reverse-arched fan blade array structure of horizontal-axis wind turbine and wind turbine

The invention provides a reverse-arched fan blade array structure of a horizontal-axis wind turbine, relating to the technical field of horizontal-axis wind turbines. The reverse-arched fan blade array structure comprises a wind wheel rotating shaft hole and multiple groups of fan blade array units uniformly mounted on the wind wheel rotating shaft hole, wherein each fan blade array unit is formedby multiple tile-shaped fan blades which are sequentially arrayed in a certain inclination angle, and the array direction of the tile-shaped fan blades of the fan blade array units are vertical to the circumferential end surface of the wind wheel rotating shaft hole; the edges of the tile-shaped fan blades of the fan blade array units on the same side are located on the same virtual plane so as to form a reverse-arched outline with a certain radian; and the inclination angle is an included angle of a fan blade tangent line passing through the highest point of the tile-shaped fan blades and anoutline tangent line pass
