Thermal radiation experimental device

The invention relates to the technical field of physical experiments, and discloses a thermal radiation experiment device which comprises a detection mechanism, a moving mechanism and a heat source mechanism, the bottom end of the heat source mechanism is fixedly connected with the top end of the moving mechanism, and the bottom end of the detection mechanism is fixedly connected with the top end of the moving mechanism; the heating bulb operates to heat the radiation source cube, the sliding block is moved to a proper position along the side face of the sliding rail, the distance between the thermal radiation sensor and the surface of the radiation source cube is measured through the ultrasonic range finder, and the thermal radiation sensor detects thermal radiation data. The thermistor temperature sensor detects the surface temperature of the radiation source cube, and results detected by the thermal radiation sensor, the ultrasonic range finder and the thermistor temperature sensor are transmitted to the s
