This invention belongs to the technical field of gas
turbine combustion chamber test devices, and discloses an optical
measurement device for the
spray characteristics of a gas
turbine combustion chamber based on window heating. The device includes a
combustion chamber, with an inner groove annular plate installed on one side of the top of the
combustion chamber. An annular sliding plate is rotatably connected to one side of the inner cavity of the annular plate, and an annular rack is fixedly connected to one side of the annular sliding plate. In this invention, turning on the motor causes the annular rack to mesh with a gear, driving a
threaded rod to rotate. As the
threaded rod rotates, it causes a slider to slide within the output groove. This slider then moves a moving plate and a
metal scraper. The
metal scraper, through the elasticity of a spring, contacts the surface of the inner layer of the double-layered glass. During movement, the
metal scraper cleans the carbon deposits adhering to the inner layer of the double-layered glass, preventing these deposits from affecting the
clarity of the
optical measurements.
