Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermal conductivity detection equipment, and particularly relates to a device for detecting the thermal conductivity of building thermal insulation materials. Background Technique
[0002] In order to select suitable thermal insulation materials, improve the energy utilization efficiency of buildings and reduce energy consumption, the thermal conductivity of different types and thicknesses of thermal insulation materials will be detected. The thermal conductivity detector used will create a stable temperature difference on both sides of the material through a heating system and a refrigeration system to simulate the heat transfer situation in the actual use environment. The temperature sensor monitors the temperature changes on both sides and at different positions of the material in real time and transmits the data to the data acquisition and processing system. This system analyzes and calculates the collected temperature data and time data based on Fourier's law of heat conduction, and finally obtains key parameters such as the thermal conductivity of the material;
[0003] Traditional detection devices usually can only detect a single group of materials, with low efficiency and difficult to meet the detection needs of a large number of building thermal insulation materials. Moreover, when some detection devices can synchronously detect multiple thermal insulation materials with different thicknesses and materials, the pressure device needs to be adjusted sequentially to make the test material closely fit the sensor. As a result, the operation process takes a long time, and it is difficult to ensure that the test material is closely fitted with the sensor, which will cause deviation in the detection data and cannot accurately reflect the true thermal conductivity of the material.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] As Figures 1 - 6As shown in the figure, a thermal conductivity detection device for building thermal insulation materials provided by the utility model includes a base 1. A side frame 2 is fixedly installed on the outside of the base 1, and a main controller 3 is fixedly installed on the side frame 2. A plurality of supporting platforms 4 are fixedly installed on the base 1, and the plurality of supporting platforms 4 are arranged in a ring along the upper contour of the base 1. A lower shaft plate 5 is also fixedly installed on the base 1. Two guide columns 7 are fixedly installed on the lower shaft plate 5. The upper ends of the two guide columns 7 are fixedly connected to an upper shaft plate 6. A lead screw 8 is rotatably connected between the lower shaft plate 5 and the upper shaft plate 6. A lifting beam 10 is also slidably connected between the two guide columns 7. The middle part of the lifting beam 10 is threadedly connected to the lead screw 8. Side beams 11 are fixedly installed on both sides of the lifting beam 10. Pressure rods 12 are respectively inserted and installed at both ends of the lifting beam 10 and one end of the side beam 11. A pressure block 13 is movably installed at the lower end of the pressure rod 12. A sleeve 14 is fixedly installed at the lower end of the lifting beam 10. An adjusting ring 15 is movably installed on the outside of the sleeve 14. A synchronizing rod 16 is movably connected between the sleeve 14 and the lead screw 8. A slide rod 17 is slidably connected inside the synchronizing rod 16.
[0025] As Figure 1 shown, a hand wheel 9 is fixedly installed at the upper end of the lead screw 8.
[0026] As Figures 1 - 2 shown, a telescopic groove 18 is opened at the lower end of the pressure rod 12. A fixing block 19 is fixedly installed at the upper end of the pressure block 13. The upper end of the fixing block 19 is of a slope structure. A T-shaped shaft 20 is fixedly installed at the upper end of the fixing block 19. The T-shaped shaft 20 is inserted and installed in the telescopic groove 18. With the cooperation of the pressure rod 12, the lifting beam 10 or the side beam 11, the pressure block 13 can press on thermal insulation materials made of different raw materials and with different thicknesses by its own gravity under the rotation of the lead screw 8.
[0027] As Figures 3 - 6As shown, a rotating groove 21 is formed on the outer side of the casing 14. A plurality of T-shaped sliding grooves 22 are formed in the casing 14 above the rotating groove 21. The arrangement of the casing 14 can provide conditions for the connection between the synchronous rod 16 and the corresponding lead screw 8. A rubber damping layer is coated on the inner side of the adjusting ring 15. A plurality of inserting rods 23 are fixedly installed on the adjusting ring 15. The adjusting ring 15 is rotatably installed in the rotating groove 21. A slope is formed on one side of the inserting rod 23 close to the T-shaped sliding groove 22. After rotating the adjusting ring 15, the plurality of inserting rods 23 can be driven to rotate synchronously, so that the plurality of inserting rods 23 can synchronously extrude and move the plurality of sliding rods 17. One end of the synchronous rod 16 is fixedly installed with a T-shaped slider 24. An embedding groove 25 is formed in the synchronous rod 16 close to the T-shaped slider 24. The other end of the synchronous rod 16 is fixedly installed with a hoop 27. A fixed shaft 26 is fixedly installed in the synchronous rod 16 close to the hoop 27. The T-shaped slider 24 is slidably connected in one of the T-shaped sliding grooves 22. The hoop 27 is fixedly installed on the outer side of one of the pressure rods 12. Connecting the pressure rod 12 and the casing 14 through the synchronous rod 16 can make the synchronous rod 16 and the sliding rod 17 always above the fixed block 19 during the lifting process of the pressure rod 12. The through hole on one side of the sliding rod 17 close to the hoop 27 is inserted on the fixed shaft 26, and a compression spring is sleeved on the fixed shaft 26. A fixed clamp 28 is also fixedly installed on one side of the sliding rod 17. An L-shaped push rod 29 is fixedly installed in the fixed clamp 28. One end of the L-shaped push rod 29 abuts against the fixed block 19. After the sliding rod 17 is extruded and displaced by the inserting rod 23, the sliding rod 17 can synchronously push the L-shaped push rod 29 through the fixed clamp 28, and then the fixed block 19 can be pressed down by a certain process, so that the pressing block 13 can apply a pressure to the tested thermal insulation material through the fixed block 19 by means of the thrust of the L-shaped push rod 29, ensuring the full contact between the two test pressing pieces and the sensor.
[0028] It should be noted that the present utility model is a device for detecting the thermal conductivity of building thermal insulation materials. When detecting thermal insulation materials with different thicknesses, two thermal insulation materials can be stacked and placed on one of the supporting platforms 4 first, and the sensor is inserted between the two thermal insulation materials. Then, the handwheel 9 at the upper end of the lead screw 8 is rotated, and the lead screw 8 rotates. Since the middle part of the lifting beam 10 is threadedly connected to the lead screw 8, and the lifting beam 10 slides between the two guide columns 7, the rotation of the lead screw 8 will drive the lifting beam 10 to move downward. The side beams 11 fixedly installed on both sides of the lifting beam 10 will move synchronously. The pressure rods 12 inserted and installed at both ends of the lifting beam 10 and one end of the side beams 11 will also move up and down accordingly. The pressure rods 12 drive the synchronous rod 16 to move synchronously through the hoop 27. Then, the other end of the synchronous rod 16 slides the pressure block 13 movably installed at the lower end of the pressure rod 12 through the T-shaped slider 24 in the T-shaped chute 22. With the cooperation of the lead screw 8 and the lifting beam 10 or the side beam 11, the pressure rod 12 presses on the thermal insulation material by its own gravity. And according to the different thicknesses of the thermal insulation materials, after the pressure block 13 abuts against the thermal insulation material, if other pressure blocks 13 have not yet abutted against the corresponding thermal insulation materials, the other pressure rods 12 will continue to move downward, while the pressure block 13 that has previously abutted against the thermal insulation material will limit the downward movement of the pressure rod 12, and one end of the corresponding lifting beam 10 or side beam 11 will move downward at the pressure rod 12, thereby realizing preliminary pressure application;
[0029] Then, the adjusting ring 15 is rotated. The rubber damping layer coated on the inner side of the adjusting ring 15 can increase the friction force. The multiple insertion rods 23 on the adjusting ring 15 will rotate accordingly. The slope on the side of the insertion rod 23 close to the T-shaped chute 22 will squeeze the slide rod 17. The L-shaped push rod 29 in the fixed clamp 28 on one side of the slide rod 17 will, after the slide rod 17 is displaced by extrusion, press down the fixed block 19, so that the pressure block 13 can continue to move downward for a certain process, and additional pressure can be applied to the thermal insulation material to ensure that the test material tightly clamps the sensor. Then, through the cooperation of the main controller 3, the supporting platform 4, the sensor and the heating module, the thermal insulation material is subjected to guiding detection.
