Description

Technical Field

[0001] This utility model relates to the technical field of glass thermal insulation testing, and in particular to a testing device for the thermal insulation performance of vacuum hollow composite glass. Background Technology

[0002] When conducting thermal insulation performance tests on vacuum insulated glass, the main method involves installing the vacuum insulated glass at the window position using a simulated model room and conducting the test by sunlight exposure. To reduce experimental costs and increase efficiency, vacuum insulated glass is generally used as a partition, and the thermal performance test is conducted in conjunction with the exposure to a heat lamp.

[0003] CN216696134U discloses a laminated glass thermal insulation performance testing chamber, relating to the technical field of laminated glass quality inspection equipment. This chamber is used for testing the thermal insulation performance of laminated glass. It is an opaque, sealed chamber with a slit in the middle for placing the laminated glass. The chamber contains a control chamber and a test chamber, which are connected on adjacent sides. When the laminated glass is placed in the slit, the control chamber and test chamber are separated by the laminated glass. The control chamber contains a light source and a first thermometer, while the test chamber contains a second thermometer. This invention separates the control chamber and the test chamber using laminated glass, and analyzes the thermal insulation capacity of the laminated glass by measuring the temperature difference between the two chambers. It has the advantages of low cost and easy replacement of the laminated glass, solving the problems of high cost and harsh operating conditions in existing laminated glass thermal insulation performance testing methods.

[0004] When using the aforementioned patent, the glass is placed in a narrow slit. Different specifications of glass have different thicknesses, and the slit is prone to friction with the glass when it is placed, which can easily increase the wear and tear on the glass and affect its subsequent use. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a test device for the thermal insulation performance of vacuum hollow composite glass, so as to solve the technical problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A test device for the thermal insulation performance of vacuum hollow composite glass includes a test chamber, a heat lamp and two thermometers. A central partition is connected to the middle of the test chamber, which divides the test chamber into a heat lamp chamber and a temperature measuring chamber. A rectangular groove is formed in the middle of the side of the central partition, and an installation groove is formed on the outer side of the central partition.

[0008] The bottom side of the installation groove is rotatably connected to a rotating shaft, and the rotating shaft is inclined. There are two rotating shafts in each group. A conveyor belt is sleeved between the two rotating shafts in the same group. The two conveyor belts are inclined and form an angle between the top sides of the two conveyor belts.

[0009] The installation groove is also equipped with a sealing component for sealing the sides of the vacuum hollow composite glass, and the sides of the test chamber are also equipped with limiting components for limiting the vacuum hollow composite glass.

[0010] In a preferred embodiment, the present invention can be further configured such that: the heat lamp is connected to the top side wall of the heat chamber, and the two thermometers are respectively connected to the bottom side wall of the heat chamber and the temperature measuring chamber.

[0011] In a preferred embodiment, the present invention can be further configured such that: the sealing member includes a sealing part and a fitting part, the sealing part includes two rectangular airbag rings, the two rectangular airbag rings are respectively connected to two opposite side walls in the mounting groove, and an airbag pad is connected to the top of the mounting groove.

[0012] In a preferred embodiment, the present invention can be further configured such that: the fitting part includes an airbag column, the airbag column is fixedly connected to the side wall of the mounting groove and located between the two rectangular airbag rings, and side tubes are connected to the two opposite side walls of the mounting groove, and the two ends of the side tubes are respectively connected to the corresponding rectangular airbag rings and the airbag column.

[0013] In a preferred embodiment, the present invention can be further configured as follows: the limiting member includes two sliding grooves, which are opened opposite each other on the side of the test chamber and located at the position of the mounting groove. The two opposite side walls of the sliding grooves are also provided with arc-shaped grooves. The sliding grooves are slidably connected to sliding rods through the corresponding two arc-shaped grooves, and a U-shaped counterweight rod is connected between the two sliding rods.

[0014] In a preferred embodiment, the present invention can be further configured such that the chute is L-shaped and extends from the top sidewall of the test chamber to the middle of the sidewall of the test chamber.

[0015] In summary, this utility model has at least one of the following beneficial technical effects:

[0016] 1. The vacuum hollow composite glass thermal insulation performance testing device can push the vacuum hollow composite glass into the installation groove from the positions of the two conveyor belts during use. At the same time, it can seal the two sides of the vacuum hollow composite glass with the sealing component, thereby reducing the friction of the vacuum hollow composite glass during the thermal insulation test and thus affecting its subsequent use.

[0017] 2. In this test device for the thermal insulation performance of vacuum hollow composite glass, two rectangular airbag rings are respectively located at two rectangular slots. When the vacuum hollow composite glass is pushed into the slot, its top side will abut against the airbag pad, so that the top side of the vacuum hollow composite glass can be sealed. After the vacuum hollow composite glass abuts against the bonding part, the rectangular airbag rings will be pressurized and expanded, and then the rectangular airbag rings will abut against the vacuum hollow composite glass, thereby achieving a sealing effect.

[0018] 3.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example:

[0027] Reference Figures 1-4 This utility model discloses a test device for the thermal insulation performance of vacuum hollow composite glass, including a test chamber 1, a heat lamp 2 and two thermometers 3. A central partition 4 is connected to the middle of the test chamber 1, which divides the test chamber 1 into a heat lamp chamber 5 and a temperature measuring chamber 6. A rectangular groove 7 is opened in the middle of the side of the central partition 4, and an installation groove 8 is opened on the outer side of the central partition 4.

[0028] The mounting groove 8 is rotatably connected to the bottom side of the mounting shaft 9, and the mounting shaft 9 is inclined. There are two mounting shafts 9 in each group. A conveyor belt 10 is sleeved between the two mounting shafts 9 in the same group. The two conveyor belts 10 are inclined and form an angle between the top sides of the two conveyor belts 10.

[0029] The mounting groove 8 is also provided with a sealing member 11 for sealing the sides of the vacuum hollow composite glass, and the side of the test chamber 1 is also provided with a limiting member 12 for limiting the vacuum hollow composite glass.

[0030] In this embodiment, reference Figure 1 Insert the glass into the mounting slot 8, ensuring the bottom side of the vacuum-insulated composite glass is in contact with the two conveyor belts. The two conveyor belts are angled, forming an angle between their upward-facing sides. This allows for the production of vacuum-insulated composite glass of varying thicknesses. Anti-slip textures are created on the conveyor belts so that when the vacuum-insulated composite glass is pushed along the conveyor belts, it drives the belts to rotate. (Refer to...) Figure 2 The sealing element 11 is positioned such that a gap remains between the vacuum-insulated composite glass and the sealing element 11 within the mounting groove 8. After the vacuum-insulated composite glass and the sealing element 11 are attached and come into contact, the sealing element 11 will seal the gap on the side of the vacuum-insulated composite glass, preventing the vacuum-insulated composite glass from being subjected to friction and increasing its wear. (Refer to...) Figure 2 The limiting member 12 is further limited by the limiting member 12 provided on the side of the test chamber 1.

[0031] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the heat lamp 2 is connected to the top side wall of the heat chamber 5, and the two thermometers 3 are respectively connected to the bottom side walls of the heat chamber 5 and the temperature measuring chamber 6.

[0032] In this embodiment, reference Figure 2During the heat insulation performance test, the heat lamp 2 is connected to a controller on the outside of the test chamber 1 to control the switching and temperature adjustment of the heat lamp 2. A display is also set up to connect the heat lamp chamber 5 and the thermometer 3 in the temperature measuring chamber 6 to display the real-time temperature in the two thermometers 3. The actual temperature is measured by the thermometer 3 in the heat lamp chamber 5 under the illumination of the heat lamp 2. After the vacuum hollow composite glass is irradiated, the temperature of the light after being blocked by the vacuum hollow composite glass is measured by the thermometer 3 in the temperature measuring chamber 6, so as to facilitate the heat insulation test of the vacuum hollow composite glass.

[0033] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the sealing member 11 includes a sealing part and a fitting part. The sealing part includes two rectangular airbag rings 13. The two rectangular airbag rings 13 are respectively connected to two opposite side walls in the mounting groove 8. An airbag pad 14 is connected to the top of the mounting groove 8.

[0034] In this embodiment, reference Figure 2 The rectangular airbag ring 13 is located at the two rectangular grooves 7 respectively. When the vacuum hollow composite glass is pushed into the installation groove 8, its top side will abut against the airbag pad 14, so that the top side of the vacuum hollow composite glass can be sealed.

[0035] In addition, after the vacuum hollow composite glass comes into contact with the bonding part, the rectangular airbag ring 13 will be pressurized and expanded, and then the rectangular airbag ring will come into contact with the vacuum hollow composite glass, thereby achieving a sealing effect.

[0036] Both the airbag cushion 14 and the rectangular airbag ring 13 are made of rubber. A heat insulation layer is applied to the outer surface of the conveyor belt 10, the airbag cushion 14, the rectangular airbag ring 13, and the inner surface of the test chamber 1. This prevents the temperature inside the heat-light chamber 5 from being directly conducted to the temperature measuring chamber 6 through the rectangular airbag ring 13 and the airbag cushion 14.

[0037] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the fitting part includes an airbag column 15, which is fixedly connected to the side wall inside the mounting groove 8 and located between the two rectangular airbag rings 13. The two opposite side walls of the mounting groove 8 are each connected to a side tube 16, and the two ends of the side tube 16 are respectively connected to the corresponding rectangular airbag ring 13 and the airbag column 15.

[0038] In this embodiment, reference Figure 4The airbag column 15 is connected to the inner wall of the mounting groove 8. In addition, the airbag ring and the two rectangular airbag rings 13 are connected by a side tube 16. Therefore, after the vacuum hollow composite glass is inserted into the mounting groove 8, the vacuum hollow composite glass will press against the airbag column 15, so that the air in the airbag column 15 is introduced into the rectangular airbag ring 13 through the side tube 16. This increases the air pressure in the rectangular airbag ring 13 and presses against the vacuum hollow composite glass, achieving a sealing effect and preventing the temperature of the heat lamp 2 from being directly conducted into the temperature measuring chamber 6.

[0039] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the limiting member 12 includes two slide grooves 17, which are opened opposite each other on the side of the test chamber 1 and located at the position of the mounting groove 8. The two opposite side walls of the slide grooves 17 are also provided with arc-shaped grooves 18. The slide grooves 17 are slidably connected to slide rods 19 through the corresponding two arc-shaped grooves 18, and a U-shaped counterweight rod 20 is connected between the two slide rods 19.

[0040] In this embodiment, reference Figure 2 The two chute 17 are located on the outside of the test chamber 1, at the position of the mounting groove 8, as shown in the reference. Figure 3 The slide groove 17 has an arc-shaped groove 18 inside, and a slide rod 19 is slidably connected in the arc-shaped groove 18. A U-shaped counterweight rod 20 is connected to the outer periphery of the two slide rods 19. After the vacuum hollow composite glass is inserted into the installation groove 8, the U-shaped counterweight rod 20 is pulled to slide downward and abut against the vacuum hollow composite glass, thereby achieving the effect of confining the vacuum hollow composite glass.

[0041] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the chute 17 is L-shaped and extends from the top sidewall of the test chamber 1 to the middle of the sidewall of the test chamber 1.

[0042] In this embodiment, reference Figure 2 The slide 17 is L-shaped, which allows the U-shaped counterweight 20 to be pulled upwards and slid to the top of the test chamber 1 when the restriction on the vacuum hollow composite glass is lifted, thereby lifting the restriction on the vacuum hollow composite glass.

[0043] The implementation principle of the above embodiment is as follows: the bottom side of the vacuum hollow composite glass is attached to two conveyor belts, which are inclined so that the upward side of the two conveyor belts forms an angle, so as to limit the vacuum hollow composite glass of different thicknesses. Anti-slip texture is made on the conveyor belts so that when the vacuum hollow composite glass is pushed on the conveyor belts, it can drive the rotation of the conveyor belts. At the same time, there is a gap between the vacuum hollow composite glass and the sealing member 11 in the mounting groove 8. After the vacuum hollow composite glass and the sealing member 11 are attached and in contact, the air in the airbag column 15 is introduced into the rectangular airbag ring 13 through the side pipe 16, which increases the air pressure in the rectangular airbag ring 13 and puts it against the vacuum hollow composite glass, achieving the sealing effect and preventing the temperature of the heat lamp 2 from being directly conducted into the temperature measuring chamber 6.

[0044] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
