[0016] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0018] like Figures 1-5 As shown in the figure, an embodiment of the present invention provides a testing device for the thermal insulation performance of high silica glass fiber cloth, including a frame 1, a housing 2 provided on the upper end of the frame 1, and two testing spaces 20 arranged side by side inside the housing 2, and further including: The test component 3 includes a heat source generator 30, which can be a flame, such as an alcohol lamp, or an electric heating element, such as a heating wire. Each test space 20 has a heat source generator 30 at its bottom. A fixing mechanism 31 is provided in the middle of one of the test spaces 20. The fixing mechanism 31 is used to fix the fiberglass cloth and can move the fiberglass cloth along the test space 20 to adjust the distance between it and the heat source. A detection mechanism 32 is provided at the upper end of both test spaces 20. The detection mechanism 32 can move along the test space 20 to detect the temperature of different areas.
[0019] In another embodiment of the present invention, an insulation interlayer 200 is laid on the inner side of the test space 20; The specific implementation method is as follows: Before testing, the high-silica glass fiber cloth is clamped and fixed using the fixing mechanism 31. After the glass fiber cloth is clamped and fixed, the heat source generator 30 is activated to generate heat and begin testing. In two test spaces 20, one is equipped with glass fiber cloth, and the other is not, thus forming a control group to visually demonstrate the thermal insulation performance of the glass fiber cloth. When testing the thermal insulation performance of the glass fiber cloth, the temperature within the test space 20 is measured using the testing mechanism 32. Furthermore, the thermal insulation layer 200 laid inside the test space 20 can retain the heat dissipated during the testing process, preventing rapid heat decay and inaccurate test results.
[0020] In another embodiment of the present invention, the upper end of the outer shell 2 is provided with two cover plates 21 by snap-fitting, and the two cover plates 21 respectively seal the upper ends of the two test spaces 20; The specific implementation method is as follows: the cover plate 21 is set at the upper end of the test space 20 by a snap-fit method, which makes it convenient to quickly remove and install before testing, and makes it easier to install and remove the fiberglass cloth.
[0021] In another embodiment of the present invention, the fixing mechanism 31 includes an adjusting motor 310, which is disposed on the lower side of the test space 20. The output end of the adjusting motor 310 is provided with a lead screw 311, which is rotatably disposed in the test space 20. A lifting frame 312 is provided on the outer side of the lead screw 311 by means of threaded engagement. Two clamping frames 313 are engaged on the lifting frame 312. Handles 314 are symmetrically provided on both sides of the upper end of the lower clamping frame 313, and the handles 314 pass through the upper clamping frame 313. The specific implementation method is as follows: When testing the thermal insulation performance of the fiberglass cloth, first remove the cover plate 21 to expose the fixing mechanism 31. Then, use the handle 314 to simultaneously remove the two clamping frames 313 from the lifting frame 312. After removing the two clamping frames 313, separate them and place the cut fiberglass cloth between the two clamping frames 313, so that the two clamping frames 313 clamp and fix the fiberglass cloth. Finally, use the handle 314 to simultaneously place and clamp the two clamping frames 313 and the fiberglass cloth inside onto the lifting frame 312. The fiberglass cloth is then fixed. After completion, the cover plate 21 is reset to seal the test space 20. Once the cover plate 21 is in place, the thermal insulation performance test of the fiberglass cloth begins. During the test, the motor 310 drives the lead screw 311 to rotate, causing the lead screw 311 to move the lifting frame 312 up and down. This allows the lifting frame 312 to move the fiberglass cloth up and down via the clamping frame 313, adjusting the position between the fiberglass cloth and the heat source. This allows the thermal insulation performance of the fiberglass cloth to be tested along gradient directions at different distances from the heat source. Specifically, the motor 310 is adjusted... The motor 310 drives the lead screw 311 to rotate, causing the lead screw 311 to lift the lifting frame 312 upward. The lifting frame 312 then lifts the fiberglass cloth upward via the clamping frame 313. At this point, the fiberglass cloth is away from the heat source generator 30. The temperature on the upper side of the test space 20 is then measured. By stopping the fiberglass cloth at different distances from the heat source generator 30, the thermal insulation performance of the fiberglass cloth is measured at different positions. The motor 310 then drives the lead screw 311 to rotate in the opposite direction, causing the lead screw 311 to lift the lifting frame 312 downward. The lifting frame 312 then lifts the fiberglass cloth downward via the clamping frame 313. At this point, the fiberglass cloth is close to the heat source generator 30. The temperature on the upper side of the test space 20 is then measured. By stopping the fiberglass cloth at different distances from the heat source generator 30, the thermal insulation performance of the fiberglass cloth is measured at different positions, ensuring a sufficient and accurate assessment of the fiberglass cloth's thermal insulation performance. Furthermore, while the test space 20 with fiberglass cloth is being tested, another test space 20 without fiberglass cloth is being tested simultaneously.
[0022] In another embodiment of the present invention, the fixing mechanism 31 further includes a guide rod 315, the guide rod 315 is disposed in the test space 20, and the end of the lifting frame 312 away from the lead screw 311 is disposed on the outside of the guide rod 315 by means of sliding. The specific implementation method is as follows: the adjustment motor 310 drives the lead screw 311 to rotate, so that the lead screw 311 drives the lifting frame 312 to rise and fall, thereby allowing the lifting frame 312 to drive the fiberglass cloth to rise and fall through the clamping frame 313. When the lifting frame 312 rises and falls, the guide rod 315 can guide and limit the lifting frame 312 to prevent the lifting frame 312 from rotating during the rise and fall.
[0023] In another embodiment of the present invention, a plurality of neodymium magnets 3130 are embedded at opposite ends of the clamping frame 313, and the neodymium magnets 3130 on the clamping frame 313 are arranged correspondingly and can attract each other, and a rubber pad 3131 is provided on the outside of the neodymium magnet 3130. The specific implementation method is as follows: After the two clamping frames 313 are removed, they are separated. At the same time, the cut fiberglass cloth is placed between the two clamping frames 313, so that the two clamping frames 313 clamp and fix the fiberglass cloth. When the two clamping frames 313 clamp and fix the fiberglass cloth, the two clamping frames 313 are attracted to each other by the neodymium magnets 3130 so that the two clamping frames 313 fit tightly together, thereby clamping and fixing the fiberglass cloth. The neodymium magnets 3130 are very easy to break when they collide. In order to avoid damage to the neodymium magnets 3130, rubber gaskets 3131 are used to protect them.
[0024] In another embodiment of the present invention, the detection mechanism 32 includes a lifting cylinder 320. Each of the upper middle parts of the cover plate 21 is provided with a lifting cylinder 320. The lower end of the lifting cylinder 320 passes through the cover plate 21 and enters the test space 20. A disc 321 is provided at the lower end of the lifting cylinder 320. A temperature sensor 322 is provided in the middle of the disc 321. The specific implementation method is as follows: When testing the thermal insulation performance of fiberglass cloth in the test space 20, the lifting cylinder 320 drives the disc 321 to rise and fall along the test space 20, so that the disc 321 drives the temperature sensor 322 to a different distance from the heat source generator 30, so that the temperature sensor 322 can perform gradient detection of the temperature in the test space 20. Each test space 20 is equipped with a detection mechanism 32. In this way, the temperature sensor 322 can detect the temperature at the same position in different test spaces 20 and compare the detected values to obtain the thermal insulation performance of the fiberglass cloth.
[0025] In another embodiment of the present invention, the detection mechanism 32 further includes a drive motor 323, which is slidably disposed at the lower end of the disc 321. A bevel gear 324 is disposed at the output end of the drive motor 323, and an annular rack 325 is disposed at the lower end of the disc 321. The bevel gear 324 meshes with the annular rack 325. A temperature detection module 326 is disposed at the lower end of the drive motor 323. The specific implementation method is as follows: When comparing and testing the two test spaces 20, the lifting cylinder 320 drives the disc 321 to rise and fall along the test space 20, so that the disc 321 drives the temperature sensor 322 at different distances from the heat source generator 30. This allows the temperature sensor 322 to perform gradient detection of the temperature in the test space 20. The drive motor 323 drives the bevel gear 324 to rotate, so that the bevel gear 324 meshes with the ring rack 325 and moves. This causes the bevel gear 324 to drive the drive motor 323 to rotate on the disc 321, thereby causing the drive motor 323 to drive the temperature detection module 326 to be at different positions at the lower end of the disc 321. This allows the temperature detection module 326 to detect different areas of the test space 20. By detecting the temperature of the same area in different test spaces 20 and comparing the detected values, the thermal insulation performance of the fiberglass cloth can be accurately determined.
[0026] Working principle: Before testing, the high-silica fiberglass cloth is clamped and fixed by the fixing mechanism 31. After the fiberglass cloth is clamped and fixed, the heat source generator 30 is activated to generate heat and start the test. Fiberglass cloth is installed in one test space 20 and not installed in the other, forming a control group to visually demonstrate the thermal insulation performance of the fiberglass cloth. During the thermal insulation performance test, the temperature inside the test space 20 is measured by the testing mechanism 32. Furthermore, the insulation layer 200 laid on the inner side of the test space 20 can retain the heat emitted during the test, preventing rapid heat decay and inaccurate test results. The cover plate 21 is set at the upper end of the test space 20 by a snap-fit mechanism. The design allows for quick removal and installation before testing, making the installation and removal of the fiberglass cloth more convenient. During the fiberglass cloth insulation performance test, first remove the cover plate 21 to expose the fixing mechanism 31. Then, use the handle 314 to simultaneously remove the two clamping frames 313 from the lifting frame 312. After removing the two clamping frames 313, separate them and place the cut fiberglass cloth between the two clamping frames 313, so that the two clamping frames 313 clamp and fix the fiberglass cloth. Finally, use the handle 314 to simultaneously place and clamp the two clamping frames 313 and the fiberglass cloth within them onto the lifting frame 312. After the fiberglass cloth is fixed, reset the cover plate 21 to seal the test space 20. After the cover plate 21 is in place, the fiberglass cloth insulation performance test begins. During the test, the motor 310 drives the lead screw 311 to rotate, causing the lead screw 311 to drive the lifting frame 312 to rise and fall. The lifting frame 312 then drives the fiberglass cloth to rise and fall via the clamping frame 313, adjusting the position between the fiberglass cloth and the heat source. This allows for the testing of the fiberglass cloth's thermal insulation performance at different distances from the heat source. Specifically, the motor 310 drives the lead screw 311 to rotate, causing the lead screw 311 to drive the lifting frame 312 to rise. The lifting frame 312 then drives the fiberglass cloth to rise via the clamping frame 313. At this point, the fiberglass cloth is away from the heat source generator 30. The temperature on the upper side of the test space 20 is then measured, and the fiberglass cloth is held at a distance from the heat source generator 30. Different distances are used to perform gradient testing of the thermal insulation performance of the fiberglass cloth at different locations. The motor 310 drives the lead screw 311 to rotate in the opposite direction, causing the lead screw 311 to lower the lifting frame 312. The lifting frame 312 then lowers the fiberglass cloth via the clamping frame 313. At this point, the fiberglass cloth is close to the heat source generator 30, and the temperature on the upper side of the test space 20 is measured. By stopping the fiberglass cloth at different distances from the heat source generator 30, gradient testing of the thermal insulation performance of the fiberglass cloth at different locations is performed to ensure a sufficient and accurate assessment of its thermal insulation performance. Furthermore, while the test space 20 with fiberglass cloth is being tested, another test space 20 without fiberglass cloth is being tested simultaneously. The adjusting motor 310 drives the lead screw 311 to rotate, causing the lead screw 311 to drive the lifting frame 312 to rise and fall. This, in turn, causes the lifting frame 312 to lift and fall along with the fiberglass cloth via the clamping frame 313. During the lifting of the lifting frame 312, the guide rod 315 guides and limits its movement, preventing rotation. After removing the two clamping frames 313, they are separated, and the cut fiberglass cloth is placed between them. The clamping frames 313 clamp and fix the fiberglass cloth securely. When the two clamping frames 313 are clamping and fixing the fiberglass cloth, neodymium magnets are used to... The mutual attraction between the two clamping frames 313 ensures a tight fit, thus clamping and fixing the fiberglass cloth. Since the neodymium magnets 3130 are prone to breakage upon impact, rubber gaskets 3131 protect them from damage. When testing the thermal insulation performance of the fiberglass cloth within the test space 20, the lifting cylinder 320 moves the disc 321 up and down along the test space 20, causing the disc 321 to move the temperature sensor 322 at varying distances from the heat source generator 30, thus adjusting the distance of the temperature sensor 322 during testing. Temperature gradient detection is performed within space 20, and each test space 20 is equipped with a detection mechanism 32. Thus, the temperature sensor 322 can detect the temperature at the same location in different test spaces 20 and compare the detected values to determine the thermal insulation performance of the fiberglass cloth. During comparative testing of two test spaces 20, the lifting cylinder 320 drives the disc 321 to rise and fall along the test space 20, causing the disc 321 to move the temperature sensor 322 at different distances from the heat source generator 30, allowing the temperature sensor 322 to detect the temperature within the test space 20. During gradient detection, the drive motor 323 drives the bevel gear 324 to rotate, causing the bevel gear 324 to mesh with the ring rack 325 and move. This causes the bevel gear 324 to drive the drive motor 323 to rotate on the disk 321, thereby causing the drive motor 323 to move the temperature detection module 326 to different positions at the lower end of the disk 321. This allows the temperature detection module 326 to detect different areas of the test space 20. By detecting the temperature of the same area in different test spaces 20 and comparing the detected values, the thermal insulation performance of the fiberglass cloth can be accurately determined.
[0027] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
