[0024] The working principle of a new type of combustion chamber simulation test platform provided by the utility model is as follows: The burner heats the fire tube to simulate the infrared radiation characteristics generated during the working process of the real combustion chamber. The smoke leakage volume is adjusted by manually controlling the smoke leakage valve to simulate the smoke leakage interference of the real combustion chamber. By installing a diesel fire pot in the shelter body, the fire characteristics of the combustion chamber are simulated; the test platform can control interference singly or multiple interferences simultaneously to simulate the single interference and composite working condition interference such as interference under the disturbance of the heat source air flow on the high-temperature wall surface, smoke leakage interference, and diesel fire interference of the real combustion chamber.

One end of the pipeline 73 far from the cylinder body 71 penetrates the wall of the shelter 1 and extends to the outside of the shelter 1; a flame detector 5, which is arranged at the top inside the shelter 1. Thus, the utility model can simulate the infrared radiation characteristics and interference sources in the real combustion chamber to the greatest extent, making the test platform closer to the working environment of the real combustion chamber.

[0026] Combined with reference to Figure 1 、 Figure 2 and Figure 5As shown, the mobile cabin 1 is equipped with a fire protection system, and the fire protection system includes: a video monitoring system 6, which includes cameras and is arranged inside the mobile cabin 1; a fire protection system control box 2, which is arranged outside the mobile cabin 1; a fire extinguishing system 4, the bottle group assembly 41 of which is located outside the mobile cabin 1, and the fire extinguishing agent delivery pipe 42 of the fire extinguishing system 4 penetrates the wall of the mobile cabin 1, so that the nozzle 43 of the fire extinguishing system 4 enters the inside of the mobile cabin 1; there is data transmission between the flame detector 5 and the fire protection system control box 2.
