[0027] Please refer to Figs. 1-2 The embodiment provides a detection structure of a gas detector of a gas turbine generator set, which comprises:

[0028] A gas turning cylinder is used for collecting gas and is transversely arranged in a ventilation exhaust pipeline of the gas turbine generator set;

[0029] A partition plate is arranged in the gas turning cylinder to divide the gas turning cylinder into a first cavity and a second cavity. A plurality of air inlet through holes are distributed on the cylinder wall of the first cavity, and a plurality of air outlet through holes are distributed on the cylinder wall of the second cavity, so that the gas can be more uniformly distributed and flowed in the gas turning cylinder.

[0030] A gas detector is arranged at one end of the gas diversion cylinder to detect the gas when it flows from the first cavity into the second cavity.

[0031] A flange is arranged at the end of the gas diversion cylinder to connect and fix the gas detector; the flange has a detection cavity which is connected with the first cavity and the second cavity to form a smooth gas channel; when the gas flows out of the first cavity, it flows through the detection cavity and then enters the second cavity. During the process of flowing through the detection cavity, the gas detector can accurately detect and analyze the gas. This not only ensures the smooth flow of the gas, but also ensures that the gas detector can capture the composition change of the gas in real time and accurately, providing a strong guarantee for the safe operation of the gas turbine generator set.

[0032] In the embodiment, the gas diversion cylinder has an open structure at one end of the ventilation and exhaust pipeline of the gas turbine generator set, and the outlet end of the gas diversion cylinder extends into the open structure and is connected with the flange by welding; the sealing end of the gas diversion cylinder is connected with a support which is welded on the inner wall of the ventilation and exhaust pipeline of the gas turbine generator set. Such a structure design not only ensures the stability of the gas diversion cylinder, but also ensures the smooth flow of the gas.

[0033] In the embodiment, the fastener is a bolt and a nut, the bolt passes through the flange and the ventilation and exhaust pipeline of the gas turbine generator set and is connected with the nut, the nut is welded on the ventilation and exhaust pipeline, and a sealing rubber pad is arranged between the flange and the ventilation and exhaust pipeline; thus, a tight sealing and fastening are achieved, the leakage of harmful gas is effectively prevented, and the safety of the surrounding environment is ensured.

[0034] The gas discharged from the cover of the gas turbine generator set flows from bottom to top, enters the first cavity through the plurality of gas inlet holes, and then flows horizontally into the detection cavity of the flange; in the detection cavity, the gas is accurately collected by the gas detector for subsequent analysis and monitoring; the gas continues to rise to the second cavity and flows horizontally in the second cavity, and is discharged upward through the plurality of gas outlet holes. The whole structure cleverly uses the gas diversion cylinder to collect the gas and accurately detects the gas through the gas detector, ensuring the smooth flow of the gas and the accuracy of the monitoring, and facilitating the observation and recording of the staff at any time.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
