The invention provides a spray pipe for generating power through turboshaft engine tail gas. The spray pipe comprises a spray pipe outer culvert casing (1), a spray pipe inner culvert casing (2), a piston (6), a spring (8), a spring support (7), a permanent magnet (3), a connecting rod (13) and a pressure adjustment valve (11). An outer culvert channel is formed between the spray pipe outer culvert casing and the spray pipe inner culvert casing, wherein the tail gas is guided to be discharged out of a turboshaft engine through the outer culvert channel. The piston is arranged between the spraypipe inner culvert casing and the spring support and can perform reciprocating linear motion. The spring is mounted between the piston and a linear electric generator and is in the compressed state.The permanent magnet is fixed to the spray pipe inner culvert casing and generates attraction force for the piston. The connecting rod is used for enabling the piston to be connected with the linear electric generator, and thus mechanical energy generated through linear reciprocating motion of the piston is transmitted to the linear electric generator so that the linear electric generator can generate power. The pressure adjustment valve is used for conducting pressure adjustment on the tail gas of the turboshaft engine and controllably discharging the tail gas into the outer culvert channel.
