Description

[0002] The durability of insulated laminated glass refers to the ability of the internal air gap to resist moisture penetration, structural aging, and performance degradation during use. If the durability fails, it will affect the heat insulation and sound insulation performance of the insulated laminated glass. Existing durability testing methods for insulated laminated glass involve placing the glass in a water tank and immersing it for a period of time. Durability tests are then conducted by detecting the argon content in the air gap, the dew point, and the appearance. However, the existing durability testing equipment for insulated laminated glass has a very rudimentary design. During the test, the glass is easily immersed for a long time, which can lead to problems such as failure of the lamination layer and water ingress into the air gap, indirectly causing the glass to break. When the glass breaks into fragments and falls into the water tank during the test, the glass fragments usually need to be cleaned manually, which is not only inconvenient to operate but also poses a significant safety hazard.

[0017] This utility model relates to a durability testing device for insulated laminated glass, such as... Figure 1-8As shown, the system includes a water tank 1, which consists of a side plate 110 and a bottom plate 120. The bottom edge of the side plate 110 is sealed to the bottom plate 120. Inside the water tank 1, two lifting plates 3 are vertically driven by a lifting mechanism 2. At the upper end of the bottom plate 120, a push plate 5 is driven along the length of the bottom plate 120 by a horizontal transmission mechanism 4, and the push plate 5 contacts the upper end of the bottom plate 120. At the end of the bottom plate 120 away from the push plate 5, a waste discharge hole 6 is provided in the transmission direction of the push plate 5. Inside the waste discharge hole 6, a device is movably installed that is sealed to the waste discharge hole 6. A sealing plate 7 is connected to the bottom plate 120, and a waste box 8 is located below the waste discharge hole 6. A side plate 110 and a bottom plate 120 are connected, with the side plate 110 sealed to the upper edge of the bottom plate 120, forming the overall structure of the water tank 1. Water is added from above the side plate 110 to ensure the water level in the water tank 1 meets the immersion height requirements of the test glass. A lifting mechanism 2 and two lifting plates 3 are used. The lifting mechanism 2 moves the two lifting plates 3 above the water tank 1, placing the test glass flat on top of the two lifting plates 3. The lifting mechanism 2 then moves the two lifting plates 3 again... The lifting plate 3 descends into the water tank 1, immersing the test glass in water. After a period of immersion, the lifting mechanism 2 raises the test glass above the water tank 1. The durability of the test glass is then tested through visual inspection, hollow dew point measurement, and hollow argon content measurement. A horizontal transmission mechanism 4, a pusher plate 5, and a waste discharge hole 6 are used. When the test glass breaks, the glass fragments sink to the base plate 120. The horizontal transmission mechanism 4 drives the pusher plate 5 to move towards the waste discharge hole 6, pushing the glass fragments towards the waste discharge hole 6 from the top of the base plate 120. The glass fragments in the water tank 1 are conveniently and efficiently cleaned through the discharge hole 6. By setting a sealing plate 7 and a waste bin 8, the sealing plate 7 is sealed to the waste discharge hole 6, ensuring that the inside of the waste discharge hole 6 is sealed. The upper end of the waste bin 8 is connected to its interior. When cleaning glass fragments, the sealing plate 7 is opened, and the glass fragments can be easily recycled through the waste bin 8 located below the waste discharge hole 6. Compared with the prior art, the cleaning efficiency of glass fragments is improved, direct contact with glass fragments is avoided, and safety hazards are reduced, thus solving the problem to be solved by this utility model.

[0018] In an embodiment of this utility model, the lifting mechanism 2 includes a bracket 201, a lifting motor 202, a first lead screw 203, two guide rods 204, a transmission seat 205, an upper mounting plate 206, and a lower mounting plate 207. The bracket 201 is disposed on the side of the water tank 1. The upper mounting plate 206 and the lower mounting plate 207 are respectively fixedly connected to the upper and lower ends of one side of the bracket 201. The two ends of the first lead screw 203 are rotatably connected to the middle of the upper mounting plate 206 and the lower mounting plate 207, respectively. The two guide rods 204 are symmetrical about the two sides of the first lead screw 203, and the two ends of the two guide rods 204 are respectively fixedly connected to the upper mounting plate 206 and the lower mounting plate 207. The two sides of the transmission seat 205 are slidably connected to the two guide rods 204 in the vertical direction. The transmission seat 205 is vertically connected to the first lead screw 203 in the middle. The system consists of a bracket 201, a lifting motor 202, the first lead screw 203, two guide rods 204, a transmission seat 205, an upper mounting plate 206, and a lower mounting plate 207. The bracket 201 is located on the side of the water tank 1 and serves as the mounting structure for the lifting mechanism 2. The output end of the lifting motor 202 drives the first lead screw 203 to rotate between the upper mounting plate 206 and the lower mounting plate 207. The rotation of the first lead screw 203 drives the transmission seat 205 to move along the length of the guide rod 204. The vertical movement of the transmission seat 205 drives the lifting plate 3 to move vertically, thus enabling the lifting plate 3 to move between the inside and above the water tank 1.

[0019] In this embodiment of the invention, one side of the transmission base 205 extends above the water tank 1. Two lifting plates 3 move relative to the transmission base 205 via a shifting mechanism 9, and simultaneously move from the center of the transmission base 205 to both sides, or simultaneously move from both sides of the transmission base 205 towards the center. The shifting mechanism 9 includes a shifting motor 91, positive and negative lead screws 92, two transmission nuts 93, and two slide rails 94. The two ends of the positive and negative lead screws 92 are rotatably connected to the upper end of the transmission base 205 via fixed seats. The shifting motor 91 is fixedly connected to the upper end of the transmission base 205 via a motor fixed seat and installed at one end of the positive and negative lead screws 92 to drive the positive and negative lead screws 92 to rotate circumferentially. The two transmission nuts 93 are respectively installed on the tops of the two lifting plates 3, and the two transmission nuts 93 are respectively connected to the two threaded sections of the positive and negative lead screws 92. The two slide rails 94 are symmetrically fixedly connected to the upper and lower ends of the transmission base 205. The lifting plate 3 is simultaneously slidably connected to two slide rails 94 along the length of the slide rails 94. By setting up a shift motor 91, positive and negative lead screws 92, two transmission nuts 93, and two slide rails 94, the output end of the shift motor 91 drives the positive and negative lead screws 92 to rotate in its circumference. The two transmission nuts 93 are respectively connected to the two sections of the positive and negative lead screws 92 through threaded transmission. When the positive and negative lead screws 92 rotate, the two transmission nuts 93 move synchronously towards each other or synchronously in opposite directions. The two transmission nuts 93 drive the two lifting plates 3 to move synchronously towards each other or synchronously in opposite directions, so that the distance between the two lifting plates 3 can be adapted to the length of the test glass. After the test glass is placed inside the water tank 1, the two lifting plates 3 move synchronously in opposite directions to the outside of the two sides of the test glass. Then, the lifting mechanism 2 is controlled to rise so that the lifting plate 3 moves above the water tank 1.

[0020] In an embodiment of this utility model, the horizontal transmission mechanism 4 includes two horizontal transmission motors 41, two second lead screws 42, and a mounting frame 43. The two horizontal transmission motors 41 are respectively mounted on the upper ends of both sides of the side plate 110 via motor mounting bases. The two second lead screws 42 are rotatably connected to the interior of both sides of the side plate 110, and are respectively installed at the output ends of the two horizontal transmission motors 41. The two second lead screws 42 are respectively connected to both ends of the mounting frame 43, and the mounting frame 43 is fixedly connected to the top of the push plate 5. By setting up the horizontal transmission motors 41, the two second lead screws 42, and the mounting frame 43, the two horizontal transmission motors 41 move synchronously, driving the two second lead screws 42 to rotate inside both sides of the side plate 110, which in turn drives the mounting frame 43 and the push plate 5 to move, so that the push plate 5 pushes the glass fragments to move.

[0021] In this embodiment of the invention, guide plates 10 are symmetrically fixedly connected to both sides of the side plate 110 about the direction of transmission of the push plate 5. The side of the guide plate 10 near the side plate 110 is higher than the side near the bottom plate 120, and the side of the guide plate 10 near the bottom plate 120 extends vertically upward. Collection plates 23 are symmetrically arranged on both sides of the push plate 5, contacting the upper end of the guide plates 10. The front of the collection plates 23 protrudes outward and has a wedge-shaped structure, with the inclination direction from the end away from the push plate 5 towards the end near the push plate 5. By providing the guide plates 10, the guide plates 10 are located near the side plate 110. One side of the guide plate 10 is higher than the side near the bottom plate 120, which facilitates the movement of glass fragments from both sides inside the water tank 1 towards the bottom center of the water tank 1. This also facilitates the concentration of glass fragments in the transmission direction of the push plate 5, improving the removal efficiency of glass fragments. By setting a collection plate 23, when the push plate 5 moves, it drives the collection plate 23 to move on the upper end of the guide plate 10, so that the glass fragments on the upper end of the guide plate 10 converge on the front of the collection plate 23, making it easier for the glass fragments to slide to the upper end of the bottom plate 120. The collection plate 23 protrudes outward from the front and has a wedge-shaped structure, which improves the collection effect of the collection plate 23.

[0022] In this embodiment of the invention, four sliding holes 11 are evenly provided in the center of the base plate 120. A column 12 is slidably installed vertically inside each of the four sliding holes 11. The bottoms of the four columns 12 are fixedly connected to the upper end of the support plate 21. A hydraulic cylinder 13 is provided at the bottom of the base plate 120. The top of the hydraulic cylinder 13 is fixedly connected to the center of the bottom of the support plate 21 via a telescopic rod, so that the four columns 12 move synchronously. Through the arrangement of the sliding holes 11, columns 12, hydraulic cylinder 13, and support plate 21, the telescopic end of the hydraulic cylinder 13... The telescopic rod moves, which in turn moves the support plate 21 vertically. The support plate 21 then moves the columns 12 vertically within the sliding hole 11, allowing the tops of the four columns 12 to move between the inside of the water tank 1 and the bottom plate 120. The tops of the four columns 12 are then moved to the top of the bottom of the water tank 1, and the four bottom corners of the test glass contact the tops of the four columns 12, improving the stability of the test glass inside the water tank 1. When cleaning up glass fragments, the tops of the four columns 12 are moved back into the bottom plate 120.

[0023] In an embodiment of this utility model, a drain hole 14 is provided inside the base plate 120, and a drain pipe 15 is fixedly connected to the bottom of the drain hole 14. A shut-off valve 16 is provided inside the drain pipe 15. By setting up the drain hole 14, the drain pipe 15 and the shut-off valve 16, when the water tank 1 drains, the shut-off valve 16 is opened so that the water inside the water tank 1 enters the drain pipe 15 through the drain hole 14. By connecting a pipe to the bottom discharge end of the drain pipe 15, it is convenient for the water to be discharged from the bottom of the drain pipe 15.

[0024] In this embodiment of the invention, three annular grooves 17 are sequentially formed vertically inside the sliding hole 11. From the top to the bottom of the sliding hole 11, a dustproof ring 18, a sealing ring 19, and a wear-resistant ring 20 are sequentially arranged in the three annular grooves 17. The inner walls of the dustproof ring 18, sealing ring 19, and wear-resistant ring 20 are all slidably connected to the surface of the column 12. By providing the annular grooves 17, dustproof ring 18, sealing ring 19, and wear-resistant ring 20, and by the vertically formed grooves inside the sliding hole 11... A dustproof ring 18, a sealing ring 19, and a wear-resistant ring 20 are sequentially arranged. The dustproof ring 18 fits tightly against the surface of the column 12, preventing external dust and impurities from entering the sliding gap when the column 12 slides. When the column 12 slides, the sealing ring 19 can always fit tightly against the surface of the column 12, filling the gap and preventing water in the water tank 1 from leaking out through the sliding hole 11. The wear-resistant ring 20 provides sliding guidance for the column 12, avoiding uneven force and local wear on the sealing ring 19 caused by the column 12 shifting.

[0025] In this embodiment of the utility model, the bottom of the lifting plate 3 is located between two adjacent sides below the two guide plates 10. By setting the bottom of the lifting plate 3 between two adjacent sides below the two guide plates 10, it is easier for the bottom of the lifting plate 3 to move to the upper end of the base plate 120, thereby increasing the moving distance of the lifting plate 3 inside the water tank 1.

[0026] In an embodiment of this utility model, support legs 22 are provided at the four bottom corners of the bottom plate 120. By providing support legs 22, the stability of the water tank 1 on the ground is improved.

[0027] In use, first, add water to the water tank 1. After adding water, control the lifting mechanism 2 to raise the lifting plate 3 above the water tank 1. Then, place the test glass flat on the upper ends of the two lifting plates 3. At the same time, activate the hydraulic cylinder 13, which drives the column 12 to move inside the sliding hole 11, raising the top of the column 12 above the base plate 120. Control the lifting mechanism 2 to descend, and the lifting plate 3 lowers the test glass into the water tank 1 until the bottom of the test glass is completely submerged in water. Simultaneously, ensure that the bottom center of the test glass is evenly in contact with the four columns 12. Continue to control the lifting plate 3 to descend below the test glass. Then, control the shifting mechanism 9 to move the two lifting plates 3 away from the sides of the test glass. On both sides of the glass, the lifting mechanism 2 is raised, causing the lifting plate 3 to move above the water tank 1. After a period of time, the lifting plate 3 drives the test glass to move above the water tank 1 for durability testing. When cleaning the glass fragments, the shut-off valve 16 is opened, and the water in the water tank 1 enters the drain pipe 15 through the drain hole 14 and then exits through the bottom discharge end of the drain pipe 15. After the water in the water tank 1 is drained, the tops of the four columns 12 are moved to the inside of the base plate 120. Then, the two horizontal transmission motors 41 move synchronously, driving the two second lead screws 42 to rotate inside the side plates 110, driving the mounting bracket 43 and the push plate 5 to move. The push plate 5 pushes the glass fragments toward the waste discharge hole 6. At the same time, the sealing plate 7 is opened, allowing the glass fragments to enter the waste bin 8.
