description The utility model relates to the technical field of flue gas sampling devices, in particular to a high-temperature flue gas sampling device for a near wall surface of a water cooling wall of a coal-fired boiler. In order to solve the problems that a sampling device and a smoke outlet need to be assembled by using various mounting parts, and the mounting and using efficiency of the sampling device is low, the following technical scheme is provided: the sampling device comprises a water-cooled wall tube and a fin, the fin is provided with a sampling port, one side of the sampling port is hermetically connected with the sampling device, and the other side of the sampling port is hermetically connected with the water-cooled wall tube. A mounting mechanism is connected between the sampling device and the sampling port, the mounting mechanism comprises a mounting frame, a mounting groove is formed in the mounting frame, a lifting plate is mounted at the top of the mounting frame, and an abutting block is connected
