Description

Technical Field

[0001] This utility model belongs to the technical field of insulation board testing devices, specifically relating to an experimental device for the thermal insulation performance of insulation boards. Background Technology

[0002] Vacuum insulation panels are a type of vacuum insulation material that can effectively prevent heat transfer caused by air convection, thus significantly reducing the thermal conductivity. Vacuum insulation panels are mainly composed of core material, barrier film, and getter. The core material is the key factor that determines the thermal insulation performance of vacuum insulation panels. Common core materials include granular core material, foam core material, fiber core material, and composite core material. Among them, fiber core material has advantages such as low density, small diameter, and low thermal conductivity.

[0003] Currently, to ensure good quality during the production of insulation panels, it is necessary to test their thermal insulation performance. Existing testing methods mostly involve heating one side of the insulation panel and measuring its temperature there. However, this method is not suitable for simulating real-world conditions to fully assess the insulation performance. It cannot test the impact of varying distances between the heat source and the insulation panel on its performance. Furthermore, the insulation performance may differ between different parts of the panel due to manufacturing processes. Manual testing is inconvenient because it's difficult to maintain a fixed heating position for extended periods, wasting manpower. It also hinders accurate testing of specific areas on insulation panels of different sizes, leading to significant errors in testing and potentially affecting the overall production quality. Utility Model Content

[0004] To address the above issues and overcome the shortcomings of existing technologies, this utility model provides a thermal insulation performance testing device for thermal insulation boards. This device accurately simulates the thermal insulation performance of thermal insulation boards when the heat source and the insulation board are at different distances in reality, making it more realistic. The simulated heat source mechanism can correspond to different parts of the side of the insulation board, facilitating the testing of the thermal insulation performance of different parts of the insulation board, thereby further improving the accuracy of the test and the production quality of the insulation board. At the same time, it does not require manual operation, saving manpower and making it more convenient to use when testing the thermal insulation performance of insulation boards.

[0005] An experimental device for testing the thermal insulation performance of a heat insulation board includes a base, a first movable rod, and a second movable rod. A first lead screw mechanism is disposed below the base, capable of driving the first movable rod to move laterally. The first movable rod is tractively connected to the first lead screw mechanism and passes through the upper surface of the base. A support frame is inserted into the top of the first movable rod, and a second lead screw mechanism is disposed at the top of the support frame. A movable clamping mechanism for clamping the heat insulation board is tractively connected externally to the second lead screw mechanism. An adjustable temperature detection mechanism is slidably connected to the side of the support frame away from the second movable rod. The second movable rod is slidably connected laterally to the upper surface of the base, and a sliding frame is vertically disposed externally on its exterior. A lateral movable frame is slidably connected externally to the sliding frame, and an adjustable simulated heat source mechanism is disposed on the side of the lateral movable frame near the first movable rod.

[0006] Preferably, the first lead screw mechanism includes a first motor, a pulley, a belt, and a lead screw. There are two lead screws, and the two lead screws are rotatably connected to both sides of the lower surface of the base. The same end of each of the two lead screws is fixedly connected to a pulley, and the belt drive is connected to the outside of the two pulleys. The output shaft of the first motor is connected to one of the pulleys through a spline.

[0007] Preferably, the second lead screw mechanism includes a second motor and a bidirectional lead screw, the bidirectional lead screw being rotatably connected to the top of the support frame and one end of which is connected to the output shaft of the second motor via a spline, the second motor being fixedly mounted on the top of the side of the support frame.

[0008] Preferably, the movable clamping mechanism includes a lead screw slider, a lifting plate, and a spring clip. There are two lead screw sliders, and both lead screw sliders are slidably connected to the inside of the top of the support frame and connected to both sides of the middle of the bidirectional lead screw via threaded transmission. The lifting plate is fixedly connected to the bottom end of the lead screw slider, and the spring clip is fixedly installed at the bottom end of the lifting plate.

[0009] Preferably, the temperature detection mechanism includes a slide, a rotating sleeve, a telescopic rod, and a temperature sensor. The slide is slidably connected to the top of the support frame on the side away from the second moving rod. A locking knob is threaded through the top of the rotating sleeve and threaded through one end of the rotating sleeve on the side of the slide. The telescopic rod passes through the bottom of the rotating sleeve and the temperature sensor is fixedly installed at the bottom of the side of the telescopic rod.

The heating plate is fixedly installed at the bottom of the fixed sleeve near the first moving rod.

[0011] The beneficial effects of the above technical solution are as follows:

[0012] This thermal insulation performance testing device for thermal insulation panels, through the configuration of a first moving rod, a second moving rod, a movable clamping mechanism, a temperature detection mechanism, and a simulated heat source mechanism, vertically clamps the thermal insulation panel to be tested within the movable clamping mechanism. The movable clamping mechanism facilitates the clamping and fixing of thermal insulation panels of different sizes. The simulated heat source mechanism can simulate a heat source on one side of the thermal insulation panel and can be set to different temperatures. After continuous heating of the thermal insulation panel, the temperature on the other side of the thermal insulation panel is detected by the temperature detection mechanism on the other side, thereby determining the thermal insulation performance of the thermal insulation panel against heat sources of different temperatures. Furthermore, both the first and second moving rods can move laterally, facilitating the adjustment of the distance between the thermal insulation panel and the simulated heat source mechanism. This allows for accurate simulation of the thermal insulation performance of the thermal insulation panel when the heat source and the thermal insulation panel are at different distances in reality, making it more realistic. The simulated heat source mechanism can correspond to different parts of the side of the thermal insulation panel, facilitating the detection of the thermal insulation performance of different parts of the thermal insulation panel, thereby further improving the accuracy of the test and the production quality of the thermal insulation panel. At the same time, it eliminates the need for manual operation, saving manpower and making it more convenient to use for testing the thermal insulation performance of thermal insulation panels.

[0020] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 6 The embodiments are described in detail below.

[0021] This embodiment provides a test device for the thermal insulation performance of an insulation board, as shown in the attached diagram. Figure 1-6 As shown, the system includes a base 1, a first moving rod 2, and a second moving rod 3. A first lead screw mechanism is provided below the base 1 to drive the first moving rod 2 to move laterally. The first lead screw mechanism includes a first motor 7, a pulley 8, a belt 9, and a lead screw 10. There are two lead screws 10, and the two lead screws 10 are rotatably connected to both sides of the lower surface of the base 1. The same end of each of the two lead screws 10 is fixedly connected to the pulley 8, and the belt 9 is driven to the outside of the two pulleys 8. The output shaft of the first motor 7 is connected to one of the pulleys 8 through a spline. When the first motor 7 is running, it can drive the lead screws 10 on both sides to rotate synchronously through the pulley 8 and the belt 9, thereby driving the first moving rod 2 to move laterally through the thread, which facilitates the adjustment of the lateral position of the insulation plate on the first moving rod 2.

[0022] The first moving rod 2 is driven and connected to the first lead screw mechanism and passes through the upper surface of the base 1. A support frame 4 is inserted into the top of the first moving rod 2. There are two first moving rods 2, and the two first moving rods 2 are driven and connected to the same part outside the two lead screws 10. The top of the side of each of the two first moving rods 2 is threaded with fixing bolts for fixing the support frame 4. The support frame 4 has vertical positioning holes on both sides. The end of the fixing bolt passing through the side of the first moving rod 2 is threaded into the corresponding positioning hole, which can fix the height of the support frame 4 and facilitate the adjustment of the height of the support frame 4, so as to meet the needs of the required testing. The height of the support frame 4 is adjusted according to the size of the hot plate. A second lead screw mechanism is provided at the top of the support frame 4. The second lead screw mechanism includes a second motor 11 and a bidirectional lead screw 12. The bidirectional lead screw 12 is rotatably connected to the top of the support frame 4, and one end is connected to the output shaft of the second motor 11 through a spline. The second motor 11 is fixedly installed on the top of the side of the support frame 4. The second motor 11 can drive the bidirectional lead screw 12 to rotate. The two sides of the middle part of the bidirectional lead screw 12 have opposite spiral structures, which can drive the lead screw sliders 13 on both sides to move relative to each other, so as to facilitate the adjustment of the distance between the two movable clamping mechanisms, thereby facilitating the clamping and fixing of insulation plates of different sizes.

[0023] The external transmission connection of the second lead screw mechanism is a movable clamping mechanism for clamping the insulation board. The movable clamping mechanism includes a lead screw slider 13, a lifting plate 14, and a spring clip 15. There are two lead screw sliders 13, and both lead screw sliders 13 are slidably connected to the inside of the top of the support frame 4 and connected to both sides of the middle of the bidirectional lead screw 12 by threaded transmission. The lifting plate 14 is fixedly connected to the bottom end of the lead screw slider 13, and the spring clip 15 is fixedly installed at the bottom end of the lifting plate 14. The insulation board can be clamped in the spring clips 15 on both sides, so that the insulation board can be vertically suspended below the support frame 4 and correspond to the simulated heat source mechanism.

[0024] An adjustable temperature detection mechanism is slidably connected to the side of the support frame 4 away from the second moving rod 3. The temperature detection mechanism includes a slide 16, a rotating sleeve 17, a telescopic rod 18, and a temperature sensor 19. The slide 16 is slidably connected to the top of the support frame 4 away from the second moving rod 3. A groove is provided on the top of the side of the support frame 4 for the slide 16 to slide. A locking knob 20 is threaded through the top of the rotating sleeve 17, and one end of the locking knob 20 is threaded through the side of the slide 16. By tightening the locking knob 20, the rotating sleeve 16 can be locked. 7. The device is fixed in a horizontal, inclined, or vertical position, which facilitates the temperature sensor 19 to detect the temperature of different parts of the insulation board. The telescopic rod 18 passes through the bottom of the rotating sleeve rod 17, and the temperature sensor 19 is fixedly installed on the bottom side of the telescopic rod 18. The bottom side of the rotating sleeve rod 17 is threaded with a fixing bolt for fixing the telescopic rod 18. The side of the telescopic rod 18 is vertically and equidistantly provided with threaded holes. The fixing bolt is connected to different threaded holes to fix the extension length of the telescopic rod 18, which facilitates the adjustment of the position of the temperature sensor 19.

[0025] The second moving rod 3 is slidably connected to the upper surface of the base 1, and a sliding frame 5 is vertically mounted on its exterior. Both sides of the sliding frame 5 are sleeved on the sides of the second moving rod 3 and can slide vertically on its exterior. Insert rods 25 are inserted into both sides of the sliding frame 5, and tension springs 26 are sleeved on the exterior of the insert rods 25. Multiple insertion holes 27 are vertically and equidistantly opened on both sides of the second moving rod 3. One end of the insert rod 25 is inserted into the corresponding insertion hole 27 on the side of the sliding frame 5, which can adjust and fix the height of the sliding frame 5. The tension springs 26 can exert an inward pulling force on the insert rods 25 to ensure that the insert rods 25 can be tightly inserted into the corresponding insertion holes 27.

[0026] A transverse sliding frame 6 is slidably connected to the outside of the sliding frame 5. An adjustable simulated heat source mechanism is provided on the side of the transverse sliding frame 6 near the first moving rod 2. The simulated heat source mechanism includes a fixed sleeve 21, an adjusting plate 22, a heating lamp body 23, and a heating plate 24. The fixed sleeve 21 is fixedly connected to the side of the transverse sliding frame 6 near the first moving rod 2, and adjustable plates 22 that can extend and retract are inserted into both sides and the top. Locking bolts are threaded to the side of the adjusting plate 22 near the fixed sleeve 21. Tightening or loosening the locking bolts can fix the extended state of the adjusting plate 22. The position of the heating lamp body 23 on the adjustment plate 22 can be adjusted to facilitate the adjustment of the overall heat source range according to the situation. The heating lamp body 23 is fixedly installed on the side of the fixed sleeve plate 21 and the three adjustment plates 22 near the first moving rod 2. The heating plate 24 is fixedly installed at the bottom of the fixed sleeve plate 21 near the first moving rod 2. By moving the second moving rod 3, the heating plate 24 can be attached to the side of the insulation board below the support frame 4, so as to heat the insulation board through direct contact, which is convenient for simulating the influence of the heat source on the insulation performance of the insulation board under different conditions.

[0027] In summary, the operating steps of this thermal insulation performance testing device are as follows:

[0028] 1. Based on the required dimensions of the insulation board to be tested, adjust the distance between the two spring clips 15 using the second motor 11 and the bidirectional lead screw 12 to clamp the insulation board inside the two spring clips 15, so that the insulation board is in a vertical position.

[0029] 2. Adjust the simulated heat source mechanism to the position corresponding to the part of the insulation board that needs to be detected by the sliding frame 5 and the transverse moving frame 6. At the same time, adjust the temperature sensor 19 to the position corresponding to the simulated heat source mechanism by rotating the sleeve rod 17 and the telescopic rod 18, so that the heating lamp body 23 can run and emit heat to the insulation board.

[0030] 3. Analyze the heat insulation performance of the heat insulation board based on the temperature data detected by the temperature sensor 19. At the same time, adjust the lateral position of the first moving rod 2 through the first lead screw mechanism to adjust the distance between the heat insulation board and the heat source. The heat insulation performance under different distances between the heat insulation board and the heat source can be detected.

[0031] 4. Alternatively, the heating lamp body 23 can be stopped, and the second moving rod 3 can be moved to attach the heating plate 24 to the side of the insulation board. The insulation performance of the insulation board under this condition can be detected by the temperature sensor 19 on the other side, so as to simulate the influence of different conditions on the insulation performance of the insulation board.
