[0021] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1 - 4As shown in the figure, the utility model provides a testing device for the thermal insulation performance of composite thermal insulation mortar, including: a detection box 2 and two mounting plates 11. On both inner surfaces of the detection box 2, support frames 3 are symmetrically and fixedly connected. Threaded rods 14 penetrate through the outer surfaces of multiple support frames 3. One ends of multiple threaded rods 14 are rotatably connected to clamping blocks 7. On the inner bottom of the detection box 2, fixing plates 4 are symmetrically and fixedly connected. One sides of the two fixing plates 4 are threaded through by lead screws 5. One ends of the lead screws 5 are rotatably connected to moving blocks 6. On one sides of the two moving blocks 6, multiple springs 10 are fixedly connected. On the adjacent sides of the two mounting plates 11, temperature sensors 12 are fixedly connected. Multiple support frames 3 are all U-shaped. On the outer surfaces of multiple support frames 3, auxiliary rods 13 penetrate through symmetrically and movably. One ends of multiple auxiliary rods 13 are respectively fixedly connected to the outer surfaces of multiple clamping blocks 7. On the outer surfaces of the two fixing plates 4, guide rods 9 penetrate through symmetrically and movably. One ends of multiple guide rods 9 are respectively fixedly connected to the outer surfaces of the two moving blocks 6. On both inner walls of the detection box 2 at the central position, rectangular plates 15 are fixedly connected. Between the outer surfaces of the two rectangular plates 15, a heating pipe 8 is fixedly connected.

[0024] The effect achieved by the entire embodiment 1 is that when testing the thermal insulation performance of the composite thermal insulation mortar, after the thermal insulation mortar is solidified and formed through a mold, the mortar material is taken out, and then the mortar material is inserted along the inner walls of the two support frames 3 in the detection box 2. Then, by rotating the two threaded rods 14 through the rotating handle 16, the threaded rods 14 rotate on the support frames 3, and through the arrangement of the auxiliary rods 13, the clamping blocks 7 move, and the mortar material is fixed inside the detection box 2 by the clamping blocks 7 and the support frames 3. Then, another mortar material is fixed inside the other two support frames 3. After the two mortar materials are fixed inside the detection box 2, by rotating the lead screw 5 through the handle 17, the lead screw 5 moves on the fixing plate 4, and under the action of the guide rod 9, the moving block 6 moves stably, so that the detection end of the temperature sensor 12 fits the surface of the mortar material, improving the subsequent detection accuracy. The temperature sensors 12 and the heating pipe 8 are both electrically connected to an external PLC control. The heating pipe 8 is started to heat one side of the two mortar materials simultaneously, and then the temperature on the surface of the mortar material is accurately measured in real time through the temperature sensors 12. The thermal insulation performance of the thermal insulation mortar is detected through the data of the temperature sensors 12. At the same time, the thermal insulation properties of the two mortar materials are detected, significantly reducing the overall detection time, and the direct comparison of the two mortar materials is more convenient, which helps to evaluate the performance differences of different thermal insulation materials.

[0025] Embodiment 2, as Figures 1 - 4As shown, a cover plate 1 is hinged to the outer surface of the detection box 2. The other ends of multiple threaded rods 14 are fixedly connected with turning handles 16. The other ends of two lead screws 5 are fixedly connected with handles 17. The ends of multiple springs 10 far from the moving blocks 6 are respectively fixedly connected with the outer surfaces of two mounting plates 11.

[0026] The overall effect achieved by the entire Embodiment 2 is that when moving the temperature sensor 12, due to the elasticity of the spring 10, the temperature sensor 12 maintains a constant contact with the surface of the mortar material, which helps to provide a more stable measured value.

[0027] Working principle: When detecting the heat preservation performance of the composite heat preservation mortar, after the heat preservation mortar is solidified and formed through a mold, the mortar material is taken out, and then the mortar material is inserted along the inner walls of the two support frames 3 in the detection box 2. Then, the two threaded rods 14 are rotated through the turning handles 16, so that the threaded rods 14 rotate on the support frames 3. With the arrangement of the auxiliary rods 13, the clamping blocks 7 move, and the mortar material is fixed inside the detection box 2 by the clamping blocks 7 and the support frames 3. Then, another mortar material is also fixed inside the other two support frames 3 on the other side. After the two mortar materials are fixed inside the detection box 2, the lead screws 5 are rotated through the handles 17, driving the lead screws 5 to move on the fixed plates 4. Under the action of the guide rods 9, the moving blocks 6 move stably, so that the detection end of the temperature sensor 12 fits with the surface of the mortar material. At the same time, under the action of the springs 10, the temperature sensor 12 maintains a constant contact with the surface of the mortar material, improving the subsequent detection accuracy. The heating tubes 8 are started to heat one side of the two mortar materials simultaneously, and then the temperature sensor 12 is used to accurately detect and measure the temperature on the surface of the mortar material in real time. The heat preservation performance of the heat preservation mortar is detected through the data of the temperature sensor 12. At the same time, the heat preservation properties of the two mortar materials are detected, significantly reducing the overall detection time, and the direct comparison of the two mortar materials is more convenient, which helps to evaluate the performance differences of different heat preservation materials.

[0028] The wiring diagram of the temperature sensor 12 and the heating tube 8 in the present utility model belongs to the common knowledge in the art. Its working principle is already known technology. Its model is selected according to actual use. Therefore, the control method and wiring arrangement of the temperature sensor 12 and the heating tube 8 are not explained in detail.

[0029] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
