[0003] Chinese Patent No. CN218445237U discloses a testing device for the thermal insulation performance of building insulation materials. The device includes a testing platform and a computer processor. The top of the testing platform has a groove, and a heat-conducting plate is installed at the top of the groove. The interior of the testing platform has a heating chamber containing an electric heating tube. Support frames are installed on both sides of the central axis of the top of the testing platform, and a lead screw is rotatably connected between the two support frames. One end of the lead screw is connected to a servo motor, and a lead screw nut is installed on the lead screw. An electric push rod is installed at the bottom of the lead screw nut, and a pressure plate is installed on the bottom output shaft of the electric push rod. A temperature sensor is installed at the bottom of the pressure plate. The device calculates... The machine processor is equipped with a PLC controller, and all electrical components on the testing platform are electrically connected to the PLC controller. However, in the aforementioned patent, when testing the thermal insulation performance of the insulation board, only the thermal insulation performance of the insulation board in the parallel direction can be tested, making it difficult to conduct a comprehensive test of the insulation board. This will reduce the testing effect of the thermal insulation performance of the insulation board. Furthermore, after the insulation board is tested, it is difficult to cool it down. A long waiting time is required for the insulation board to cool down before the next insulation board can be removed for testing, thus reducing the testing efficiency of the thermal insulation performance of the insulation board. Therefore, a device for testing the thermal insulation performance of building engineering materials is provided. Utility Model Content
