The invention discloses an infrared restraining structure for an inner heat source equipment high-temperature orifice in the ground. The infrared restraining structure comprises an infrared restraining shell. Multi-level inner wall flow guiding fins arranged at intervals are symmetrically arranged on the two transverse sides in the infrared restraining shell. The inner wall flow guiding fins incline in the high-temperature airflow flowing direction, the lengths of the inner wall flow guiding fins are gradually reduced step by step from bottom to top, and a gradual-expansion spraying pipe is formed in the infrared restraining shell, wherein a lower opening of the gradual-expansion spraying pipe is small, and an upper opening of the gradual-expansion spraying pipe is large. An injection port penetrating the hole wall is formed between every two levels of inner wall flow guiding fins. A high-temperature airflow inlet in one end of the infrared restraining shell is adjacent to a lower end inlet of the gradual-exp
