Description

Technical Field

[0001] The invention belongs to the technical field of waterproof performance detection of thermal insulation materials, and in particular relates to a device for detecting the waterproof performance of hollow glass microbead thermal insulation materials. Background Art

[0002] Glass microspheres are micron-sized spherical particles made of inorganic glassy minerals, and are generally divided into two types: solid and hollow. Hollow glass microspheres contain a thin gas or vacuum inside, and their surface is vitrified to form a stable structure, characterized by light weight and low thermal conductivity. This material blocks heat transfer through the gas inside the microspheres, and combines a porous structure to reduce thermal conductivity, thereby achieving efficient thermal insulation performance. It also has additional functions such as sound insulation and fire prevention.

[0003] When conducting a waterproof test on existing hollow glass microbead thermal insulation materials, the hollow glass microbead thermal insulation materials are generally laid on the bottom of a water tank, and a diaphragm is set at the opening at the bottom of the water tank. The waterproofness of the hollow glass microbead thermal insulation material is then tested by measuring the amount of water leakage outside the water tank.

[0004] However, when the water pressure in the water tank is high, the hollow glass microbead insulation material in the water tank will move, resulting in different distribution of hollow glass microbead insulation materials in different areas, resulting in different permeability in various areas of the water tank. In addition, since water droplets easily adhere to the bottom of the diaphragm, the speed of water droplet falling and collection is slow, which can easily cause water droplets to evaporate in the air and affect the waterproof test results of the hollow glass microbead insulation material.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1.

[0015] 2. When the double-layer diaphragm is excessively concave downward under the extrusion pressure, the No. 2 electric telescopic rod is started to increase the rotation speed, thereby increasing the smoothing speed of the smoothing roller on the bottom of the double-layer diaphragm to prevent a single area of the bottom of the double-layer diaphragm from gradually sinking downward for a long time. At the same time, the telescopic end of the No. 2 electric telescopic rod is extended, thereby increasing the smoothing force of the smoothing roller on the double-layer diaphragm; the smoothing roller can rotate by itself, thereby avoiding friction with the double-layer diaphragm when the smoothing roller moves in a circle around the No. 2 electric telescopic rod, thereby causing wear of the double-layer diaphragm; and at the same time, the winding assembly is started to tighten to avoid large deformation of the double-layer diaphragm, and in order to avoid scratches and wear between the double-layer diaphragm and the side wall of the detection port during the tightening process of the double-layer diaphragm, the protective mechanism is started to elastically support the double-layer diaphragm around the inner side of the detection port.

[0016] 3. When the leveling roller rotates, the telescopic end of the No. 2 electric telescopic rod drives the water collecting sleeve to move in a circular motion, and the water collecting sleeve can contact the bottom of the double-layer diaphragm, thereby collecting the water droplets attached to the bottom of the double-layer diaphragm due to leakage and collecting them in the No. 2 electric telescopic rod.

[0017] 4. When the detector observes that too many bubbles have entered the sleeve, the speed of the No. 2 motor is started and increased, which can increase the collection speed of the water seepage at the bottom of the double-layer diaphragm by the water collecting sleeve; the conical sleeve can collect the falling water droplets, and the No. 2 electric telescopic rod can drive the No. 2 scraper to rotate, and the No. 2 scraper can quickly gather the water droplets attached to the inner wall of the conical sleeve and collect them in the No. 2 electric telescopic rod. The cooperation between the No. 2 scraper and the water collecting sleeve can improve the collection speed of the leaking water flow. At the same time, the air cooler in the No. 2 electric telescopic rod can further accelerate the downward convergence of the water flow on the inner wall of the conical sleeve, avoiding the water droplets adhering to the inside of the conical sleeve for a long time and drying and dispersing into the air, affecting the measurement of the leakage rate of the hollow glass microbead thermal insulation material.

A pressing mechanism 5 for controlling the water pressure in the sleeve 10 is connected to an electric heating network 12. A diaphragm is provided on the electric heating network 12. A sealing sleeve 13 is fixedly provided on the bottom surface of the sealing plate 3. A temperature sensor and a pressure sensor are provided in the sleeve 10. The sealing sleeve 13 and the sleeve 10 are respectively arranged on both sides of the detection port 11. The detection port 11 and the sealing sleeve 13 are both made of transparent materials. A detector 16 capable of monitoring the lower surface of the electric heating network 12 is provided on the upper end surface of the partition 2; A leveling mechanism 6 capable of limiting and leveling the double-layer diaphragm is fixedly arranged in the sealing sleeve 13 through a support seat 14.

A temperature sensor is arranged inside the conical sleeve 15. A protective mechanism 7 capable of elastically supporting the double-layer diaphragm around the inner side of the detection port 11 is arranged on the inner side of the conical sleeve 15.

[0028] In this embodiment, hollow glass microspheres are used as a raw material for heat insulation and fixed between the double-layer membranes. The double-layer membranes are placed between the partition plate 2 and the sealing plate 3. One end of the double-layer membrane is fixed by the partition plate 2 between the partition plate 2 and the sealing plate 3, and the other end of the double-layer membrane is wound and fixed by the winding assembly 4. Fill the sleeve 10 with clean water, start the pressing mechanism 5 to increase the water pressure in the sleeve 10, and start the electric heating network 12 to heat the clean water. Observe the dripping of water flow at the lower side of the detection port 11 to judge the waterproof performance of this hollow glass microbead thermal insulation material under specific temperature and water pressure.

[0029] When the clean water in the sleeve 10 drips downward, the air in the sealing sleeve 13 diffuses into the sleeve 10, thereby generating bubbles in the sleeve 10. At this time, the bubbles can be collected by the diaphragm on the electric heating network 12. At this time, the detector 16 can monitor the area of the collected bubbles to determine the water penetration rate.

[0030] The hollow glass microsphere thermal insulation material will squeeze the double-layer diaphragm under water pressure. In order to prevent the double-layer diaphragm from deforming under the extrusion pressure, causing the density of the hollow glass microsphere thermal insulation material to decrease and affect the accuracy of the experimental results, in this embodiment, a leveling mechanism 6 is provided on the lower side of the detection port 11, and the double-layer diaphragm is limited and leveled by the leveling mechanism 6, so as to maintain the shape of the double-layer diaphragm stable; the outside of the leveling mechanism 6 is provided with a conical sleeve 15, which can collect the clean water leaking downward from the sleeve 10, and the leaked clean water can be introduced into the bottom of the sealing sleeve 13 through the leveling mechanism 6 for collection, so as to judge the leakage rate of the hollow glass microsphere thermal insulation material in the double-layer diaphragm; When the double-layer diaphragm sinks downward under the extrusion pressure, the smoothing mechanism 6 is started to increase the smoothing speed of the double-layer diaphragm, and the winding component 4 is started to tighten to avoid large deformation of the double-layer diaphragm. In order to avoid scratches and wear on the side walls of the detection port 11 during the tightening process of the double-layer diaphragm, the protective mechanism 7 is started to elastically support the double-layer diaphragm around the inner side of the detection port 11.

[0031] like Figure 4 As shown, a device for testing the waterproof performance of hollow glass microsphere thermal insulation materials provided by the present invention is provided, wherein the leveling mechanism 6 includes a second electric telescopic rod 61, a leveling roller 62 and a driving assembly 63; The support seat 14 is rotatably connected to the second electric telescopic rod 61, and the telescopic end of the second electric telescopic rod 61 is rotatably connected to the leveling roller 62. A driving assembly 63 for driving the second electric telescopic rod 61 to rotate is provided on the support seat 14. The interior of the second electric telescopic rod 61 is connected, and the bottom of the second electric telescopic rod 61 is connected to the sealing sleeve 13.

[0032] In this embodiment, the driving component 63 is started, and the driving component 63 drives the second electric telescopic rod 61 to rotate, and the second electric telescopic rod 61 drives the leveling roller 62 to roll the bottom of the double-layer diaphragm, thereby preventing the double-layer diaphragm from being under pressure for a long time and sinking excessively.

[0033] When the double-layer diaphragm is excessively concave downward under the extrusion pressure, the No. 2 electric telescopic rod 61 is started to increase the rotation speed, thereby increasing the smoothing speed of the smoothing roller 62 on the bottom of the double-layer diaphragm, avoiding a single area of the bottom of the double-layer diaphragm from gradually sinking downward for a long time. At the same time, the telescopic end of the No. 2 electric telescopic rod 61 is extended, thereby increasing the smoothing force of the smoothing roller 62 on the double-layer diaphragm; the smoothing roller 62 can rotate by itself, thereby avoiding the smoothing roller 62 from generating friction with the double-layer diaphragm when it moves in a circle around the No. 2 electric telescopic rod 61, thereby causing wear of the double-layer diaphragm.

[0034] like Figure 4As shown, a device for detecting the waterproof performance of hollow glass microsphere thermal insulation materials provided by the present invention is provided. The driving component 63 includes a No. 2 motor 631 and a gear transmission pair 632. The No. 2 motor 631 is fixedly connected to the support seat 14. The output shaft of the No. 2 motor 631 is connected to the No. 2 electric telescopic rod 61 via a gear transmission pair 632.

[0035] In this embodiment, the second motor 631 is started, and the second motor 631 drives the second electric telescopic rod 61 to rotate through the gear transmission pair 632, and the second electric telescopic rod 61 drives all the smoothing rollers 62 to roll the bottom of the double-layer diaphragm.

[0036] like Figure 6 As shown, a device for detecting the waterproof performance of hollow glass microbead thermal insulation materials provided by the present invention is provided. The telescopic end of the No. 2 electric telescopic rod 61 is fixedly connected to a water collecting sleeve 8, and the water collecting sleeve 8 is arranged on the outside of the leveling roller 62. The water collecting sleeve 8 is connected to the inside of the No. 2 electric telescopic rod 61, and the inner wall of the water collecting sleeve 8 is fixedly connected to the No. 2 scraper 17, and the No. 2 scraper 17 is in contact with the leveling roller 62.

[0037] In this embodiment, the telescopic end of the No. 2 electric telescopic rod 61 drives the water collecting sleeve 8 to perform circular motion, and the water collecting sleeve 8 can contact the bottom of the double-layer diaphragm, so that the water droplets attached to the bottom of the double-layer diaphragm due to leakage are collected and collected in the No. 2 electric telescopic rod 61. At this time, since the leveling roller 62 levels the double-layer diaphragm on one side of the water collecting sleeve 8, the water collecting sleeve 8 can fully fit with the bottom of the double-layer diaphragm and reduce the scratches between the water collecting sleeve 8 and the bottom of the double-layer diaphragm, thereby improving the water droplet collection efficiency of the water collecting sleeve 8 while effectively protecting the double-layer diaphragm. At the same time, the No. 1 scraper 9 can scrape off the moisture attached to the leveling roller 62.

[0038] When the detector 16 detects that too many bubbles have entered the sleeve 10, the rotation speed of the second motor 631 is increased, which can increase the collection speed of the water collection sleeve 8 on the water seeping from the bottom of the double-layer diaphragm.

[0039] like Figure 6 As shown, a device for detecting the waterproof performance of a hollow glass microsphere thermal insulation material provided by the present invention is provided. The fixed end of the No. 2 electric telescopic rod 61 is fixedly connected to the No. 2 scraper 17, and the No. 2 scraper 17 is in contact with the inner wall of the conical sleeve 15. An air cooler is provided inside the No. 2 electric telescopic rod 61.

[0040] In this embodiment, the conical sleeve 15 can collect the falling water droplets, and the No. 2 electric telescopic rod 61 can drive the No. 2 scraper 17 to rotate. The No. 2 scraper 17 can quickly collect the water droplets attached to the inner wall of the conical sleeve 15 and collect them in the No. 2 electric telescopic rod 61. The No. 2 scraper 17 cooperates with the water collection sleeve 8 to improve the collection speed of the leaking water flow. At the same time, the air cooler in the No. 2 electric telescopic rod 61 can further accelerate the downward convergence of the water flow on the inner wall of the conical sleeve 15, avoiding the water droplets from adhering to the inside of the conical sleeve 15 for a long time and drying and dispersing into the air, affecting the measurement of the leakage rate of the hollow glass microbead thermal insulation material.

[0041] like Figure 3 As shown, a device for detecting the waterproof performance of hollow glass microsphere thermal insulation materials provided by the present invention is provided. The winding assembly 4 includes a No. 1 motor 41 and a winding roller 42. The end face of the partition 2 is fixedly provided with a fixed seat, and the fixed seat is fixedly connected to the No. 1 motor 41. The output shaft of the No. 1 motor 41 is rotatably connected to the winding roller 42. An elastic torsion spring is connected between the winding roller 42 and the output shaft of the No. 1 motor 41, and a torque sensor is provided between the spring torsion spring and the winding roller 42.

[0042] In this embodiment, the double-layer diaphragm is wound by the winding roller 42. When the value of the torque sensor is large, it means that the double-layer diaphragm is subjected to a large tensile force. At this time, the driving component 63 is started to increase the leveling speed of the leveling roller 62, thereby increasing the supporting force of the double-layer diaphragm. At the same time, the No. 1 motor 41 is started to drive the winding roller 42 to rotate, thereby increasing the tightening force on the double-layer diaphragm to prevent the double-layer diaphragm from loosening after being reset.

[0043] like Figure 2 As shown, a device for detecting the waterproof performance of a hollow glass microsphere thermal insulation material provided by the present invention is provided. The pressing mechanism 5 includes a No. 1 electric telescopic rod 51 and a pressure plate 52. The fixed portion of the No. 1 electric telescopic rod 51 is fixedly connected to the sleeve 10. The telescopic portion of the No. 1 electric telescopic rod 51 is fixedly connected to the pressure plate 52. The pressure plate 52 is slidably and sealedly connected to the inner wall of the sleeve 10.

[0044] In this embodiment, the first electric telescopic rod 51 is started, and the first electric telescopic rod 51 drives the pressure plate 52 to press down. At this time, the water pressure in the sleeve 10 is increased through the pressure plate 52.

[0045] like Figure 5 As shown, a device for detecting the waterproof performance of hollow glass microsphere thermal insulation materials provided by the present invention is provided. The protective mechanism 7 includes an air pump 71 and an air bag 72. The air pump 71 is fixedly connected to the outer wall of the conical sleeve 15. The air bag 72 is provided on the top of the inner wall of the conical sleeve 15, and the air bag 72 is connected to the air pump 71.

[0046] In this embodiment, the air pump 71 is started to inflate the airbag 72 , thereby expanding the airbag 72 , and the double-layer diaphragm around the inner wall of the detection port 11 is protected by the airbag 72 .

[0047] Working principle: The hollow glass microsphere thermal insulation material is fixed between the double-layer diaphragm as a raw material, and the double-layer diaphragm is placed between the partition 2 and the sealing plate 3. One end of the double-layer diaphragm is fixed by the partition 2 between the partition 2 and the sealing plate 3, and the other end of the double-layer diaphragm is wound and fixed by the winding component 4; Fill the sleeve 10 with clean water, start the pressing mechanism 5 to increase the water pressure in the sleeve 10, and start the electric heating network 12 to heat the clean water. Observe the dripping of water flow at the lower side of the detection port 11 to judge the waterproof performance of this hollow glass microbead thermal insulation material under specific temperature and water pressure.

[0048] When the clean water in the sleeve 10 drips downward, the air in the sealing sleeve 13 diffuses into the sleeve 10, thereby generating bubbles in the sleeve 10. At this time, the bubbles can be collected by the diaphragm on the electric heating network 12. At this time, the detector 16 can monitor the area of the collected bubbles to determine the water penetration rate.

[0049] The hollow glass microsphere thermal insulation material will squeeze the double-layer diaphragm under water pressure. In order to prevent the double-layer diaphragm from deforming under the squeezing force, causing the density of the hollow glass microsphere thermal insulation material to decrease and affect the accuracy of the experimental results, in this embodiment, a leveling mechanism 6 is provided on the lower side of the detection port 11. The leveling mechanism 6 limits and levels the double-layer diaphragm, thereby maintaining the shape of the double-layer diaphragm stable. Start the driving assembly 63, which drives the second electric telescopic rod 61 to rotate, and the second electric telescopic rod 61 drives the leveling roller 62 to roll the bottom of the double-layer diaphragm, thereby preventing the double-layer diaphragm from being excessively depressed due to long-term pressure.

[0050] When the double-layer diaphragm is excessively concave downward under the extrusion pressure, the No. 2 electric telescopic rod 61 is started to increase the rotation speed, thereby increasing the smoothing speed of the smoothing roller 62 on the bottom of the double-layer diaphragm, and avoiding a single area of the bottom of the double-layer diaphragm gradually sinking downward for a long time. At the same time, the telescopic end of the No. 2 electric telescopic rod 61 is extended, thereby increasing the smoothing force of the smoothing roller 62 on the double-layer diaphragm; the smoothing roller 62 can rotate by itself, thereby avoiding friction between the smoothing roller 62 and the double-layer diaphragm when the smoothing roller 62 moves in a circle around the No. 2 electric telescopic rod 61, thereby causing wear of the double-layer diaphragm; and at the same time, the winding assembly 4 is started to tighten, to avoid large deformation of the double-layer diaphragm, and in order to avoid scratches and wear on the side wall of the detection port 11 during the tightening of the double-layer diaphragm, the protective mechanism 7 is started to elastically support the double-layer diaphragm around the inner side of the detection port 11.

[0051] The leveling mechanism 6 is provided with a conical sleeve 15 on the outside, through which the clean water leaking downward from the sleeve 10 can be collected. The leaked clean water can be guided to the bottom of the sealing sleeve 13 through the leveling mechanism 6 and collected, thereby determining the leakage rate of the hollow glass microsphere insulation material in the double-layer diaphragm; When the leveling roller 62 rotates, the telescopic end of the No. 2 electric telescopic rod 61 drives the water collecting sleeve 8 to move in a circular motion, and the water collecting sleeve 8 can contact the bottom of the double-layer diaphragm, so that the water droplets attached to the bottom of the double-layer diaphragm due to leakage are gathered and collected in the No. 2 electric telescopic rod 61. At this time, since the leveling roller 62 levels the double-layer diaphragm on one side of the water collecting sleeve 8, the water collecting sleeve 8 can fully fit with the bottom of the double-layer diaphragm and reduce the scratches between the water collecting sleeve 8 and the bottom of the double-layer diaphragm, thereby improving the water droplet collection efficiency of the water collecting sleeve 8 while effectively protecting the double-layer diaphragm.

[0052] When the detector 16 observes that too many bubbles have entered the sleeve 10, the speed of the No. 2 motor 631 is started and increased, which can increase the collection speed of the water seepage at the bottom of the double-layer diaphragm by the water collecting sleeve 8; the conical sleeve 15 can collect the falling water droplets, and the No. 2 electric telescopic rod 61 can drive the No. 2 scraper 17 to rotate, and the No. 2 scraper 17 can quickly gather the water droplets attached to the inner wall of the conical sleeve 15 and collect them into the No. 2 electric telescopic rod 61. The No. 2 scraper 17 cooperates with the water collecting sleeve 8 to improve the collection speed of the leaking water flow. At the same time, the air cooler in the No. 2 electric telescopic rod 61 can further accelerate the downward convergence of the water flow on the inner wall of the conical sleeve 15, to prevent the water droplets from adhering to the inside of the conical sleeve 15 for a long time and drying and dispersing into the air, affecting the measurement of the leakage rate of the hollow glass microbead thermal insulation material.
