Description

Technical Field

[0001] This utility model relates to the field of silicone sealant technology, specifically to a silicone sealant weather resistance testing device. Background Technology

[0002] Silicone sealants are widely used in building curtain walls, door and window assembly, and other scenarios. Their weather resistance directly affects structural safety and service life. Therefore, testing devices are needed to simulate different environments in order to test the weather resistance of silicone sealants.

[0003] 1. When the silicone sealant is exposed to sunlight and is at a high temperature under simulated sunlight, the testing device needs to use a heating element. However, when simulating rainfall, water needs to be sprayed. At this time, the water will be sprayed directly onto the heating element, which can easily cause damage to the heating element over time, resulting in a shorter service life of the heating element and thus poor stability of the testing device during operation.

[0004] 2. Furthermore, the detection device does not have a mechanism for recycling and reusing the spray water during simulated rainfall. This not only wastes water resources but also increases the operating cost of the detection device, resulting in higher operating costs and poorer practical performance. Utility Model Content

[0005] To address the above problems, this utility model provides a device for testing the weather resistance of silicone sealant, thus solving the aforementioned issues.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a silicone sealant weather resistance testing device, comprising a testing device housing and a control device body connected to the top of the testing device housing, wherein a placement rack is connected inside the testing device housing, and an upper fixing plate and a lower support plate are respectively connected to the two inner sides of the testing device housing;

[0007] The top of the lower support plate is connected to several heating tubes. One side of the lower support plate is wavy. The upper fixed plate is rotatably connected to a rotating frame. The bottom of the rotating frame is connected to a baffle plate. The bottom of the baffle plate is rotatably connected to the interior of the lower support plate. The diameter of the baffle plate decreases from top to bottom.

[0008] The top of the rotating frame is connected to a rotating shaft, the outside of the rotating shaft is connected to a sprocket, and the outside of the sprocket is connected to a chain. A first motor is provided on the top of one of the rotating shafts. One side of the first motor is connected to the inner side of the detection device housing, and the output end of the first motor is connected to the top of the rotating shaft for transmission.

[0009] Preferably, a water tank is connected to one side of the detection device housing, and a first water pump is installed inside the water tank. A water supply pipe is connected to one side of the first water pump.

[0010] Preferably, the outside of the water supply pipe is connected to the top of the water tank, the outside of the water supply pipe is connected to the inside of the detection device housing, and several nozzles are connected to one side of the water supply pipe.

[0011] Preferably, a second water pump is connected to the bottom of the inner side of the detection device housing, a recovery pipe is connected to one side of the second water pump, the outside of the recovery pipe is connected to the side of the detection device housing, and one end of the recovery pipe is connected to one end of the water supply pipe.

[0012] Preferably, the inside of the detection device housing is connected to a filter plate, a screw, and two guide rods.

[0013] Preferably, a second motor is connected to one side of the housing of the detection device, and the output end of the second motor is connected to one end of the screw for transmission.

[0014] Preferably, the screw is externally threaded with a movable plate, the interior of the movable plate is slidably connected to the exterior of two guide rods, a brush is connected to the bottom of the movable plate, and a scraper is connected to one side of the movable plate.

[0016] Preferably, an ultraviolet lamp is connected to the inner top surface of the detection device housing, and the water supply pipe is located in the gap of the ultraviolet lamp.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This application, through the cooperation of a baffle plate and a lower support plate, allows the baffle plate to rotate to expose the heating tube when heating with the heating tube, simulating the combined environment of silicone sealant being exposed to sunlight and high temperature under sunlight. When simulating rainfall, rotating the baffle plate to shield the heating tube can prevent water from spraying directly onto the heating tube. This solves the problem that the heating tube of the detection device lacks protection measures, and water will spray directly onto the heating tube during simulated rainfall, which will eventually cause damage to the heating tube. This helps to extend the service life of the heating tube and improve the stability of the detection device during operation.

[0019] 2. This application uses a filter plate and a recovery pipe to recycle and reuse water during simulated rainfall. When water needs to be replaced and discharged, a scraper and a brush can clean the debris on the filter plate and the inside of the filter holes. This solves the problem that the detection device cannot recycle and reuse water during simulated rainfall, which leads to high operating costs. It helps to reduce the operating costs of the detection device and improve its practical performance. Attached Figure Description

[0029] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0030] Please see Figures 1 to 8A silicone sealant weather resistance testing device includes a testing device housing 1 and a control device main body 2 connected to the top of the testing device housing 1. The testing device housing 1 has a placement rack 7 connected inside. When conducting weather resistance testing on silicone sealant, personnel open the door panel 4 and place the prepared material (silicone sealant evenly coated between two glass panes) onto the placement rack 7, then close the door panel 4. The operation of the testing device is controlled by operating the control device main body 2. At the same time, personnel can observe the working condition inside the testing device through the observation window 5. The control device main body 2 is a known technology, and those skilled in the art can and should understand its specific functions and structure, so it will not be described in detail here. The two inner sides of the testing device housing 1 are respectively connected to an upper fixing plate 8 and a lower support plate 9.

[0031] Several heating tubes 10 are connected to the top of the lower support plate 9. One side of the lower support plate 9 is wavy. A rotating frame 11 is rotatably connected inside the upper fixed plate 8. A retaining ring plate 12 is connected to the bottom of the rotating frame 11. The bottom of the retaining ring plate 12 is rotatably connected to the inside of the lower support plate 9. The diameter of the retaining ring plate 12 decreases from top to bottom. When the silicone sealant is exposed to sunlight and is in a combined environment of high temperature, the ultraviolet lamp 3 is turned on and heated in conjunction with the heating tubes 10. At this time, the output end of the first motor 15 needs to drive the rotating shaft 13 to rotate, so that the rotating shaft 13 drives the sprocket 14 to rotate. Several sprockets 14 are driven by a chain, so that several sprockets 14 will rotate synchronously.

[0032] The sprocket 14 will rotate synchronously with the shaft 13, so the shaft 13 will drive the rotating frame 11 to rotate. It should be noted that the rotating frame 11 has a rotating ring on the outside. When the rotating frame rotates, the rotating ring will rotate inside the upper fixed plate 8.

[0033] By rotating the frame 11 to drive the baffle plate 12 to rotate, the heating tube 10 is exposed, so that the heating tube 10 can quickly increase the temperature inside the detection device housing 1 to meet the requirements of the simulated sun exposure environment.

[0034] In simulated rainfall, in order to prevent water from spraying directly onto the heating tube 10, the rotating frame 11 drives the baffle plate 12 to rotate and shield the heating tube 10, so as to avoid water spraying directly onto the heating tube 10 and affecting the service life of the heating tube 10.

[0035] It should be noted that the diameter of the baffle plate 12 decreases from top to bottom, and one side of the lower support plate 9 is wavy, which is consistent with the outer diameter of several baffle plates 12. The advantage of this is that when simulating rain spraying water, the water will be sprayed on the baffle plate 12. Because the upper diameter of the baffle plate 12 is large and the lower diameter is small, the outer side of the baffle plate 12 is inclined. Therefore, the water sprayed on the baffle plate 12 will slide down due to the inclination.

[0036] Furthermore, the wavy shape of the lower support plate 9 is consistent with the outer diameter of several baffle plates 12, so when water slides down, it will not accumulate on the lower support plate 9, but will slide directly onto the filter plate 22 and reach the inner bottom of the detection device box 1.

[0037] The top of the rotating frame 11 is connected to a rotating shaft 13, the outside of the rotating shaft 13 is connected to a sprocket 14, and the outside of the sprocket 14 is connected to a chain. A first motor 15 is provided on the top of one of the rotating shafts 13. One side of the first motor 15 is connected to the inner side of the detection device housing 1, and the output end of the first motor 15 is connected to the top of the rotating shaft 13 for transmission.

[0038] A water tank 16 is connected to one side of the detection device housing 1. A first water pump 17 is installed inside the water tank 16. A water delivery pipe 18 is connected to one side of the first water pump 17. A water injection pipe is connected to one side of the water tank 16. Personnel add water for spraying into the water tank 16 through the water injection pipe.

[0039] The outside of the water supply pipe 18 is connected to the top of the water tank 16, and the outside of the water supply pipe 18 is connected to the inside of the detection device housing 1. Several nozzles 19 are connected to one side of the water supply pipe 18. When simulating a rainfall environment, the water inside the water tank 16 is transported to the water supply pipe 18 by the first water pump 17, and then sprayed through the nozzles 19 to simulate the rainfall environment.

[0040] Because the placement rack 7 has several through holes, the sprayed water will pass through the filter plate 22 to the bottom of the detection device box 1. After one round of spraying, the second water pump 20 is started to transport the water at the bottom of the detection device box 1 to the recovery pipe 21. Then the recovery pipe 21 will transport the water to the water supply pipe 18, and then spray it through the nozzle 19. In this way, the sprayed water is recycled and reused, reducing the operating cost of the detection device.

[0041] It is important to note that two valves are installed on the delivery pipe 18, located on both sides of all the nozzles 19. When the water tank 16 supplies water, the valve on the side closer to the water tank 16 is open, and the valve on the side closer to the recovery pipe 21 is closed, allowing the water supplied by the water tank 16 to be sprayed normally through the nozzles 19. At the same time, when the recovery pipe 21 is working, the valve on the side closer to the recovery pipe 21 is open, and the valve on the side closer to the water tank 16 is closed, allowing the recycled water to be sprayed normally through the nozzles 19.

[0042] A second water pump 20 is connected to the bottom of the inner side of the detection device housing 1. A recovery pipe 21 is connected to one side of the second water pump 20. The outside of the recovery pipe 21 is connected to the side of the detection device housing 1. One end of the recovery pipe 21 is connected to one end of the water supply pipe 18.

[0043] The testing device housing 1 is internally connected to a filter plate 22, a screw 23, and two guide rods 24. The sprayed water is filtered through the filter plate 22 and then enters the bottom of the testing device housing 1. It should be noted that during the weather resistance test of silicone sealant, the outer edge of the silicone sealant is exposed to ultraviolet light, high temperature, and other environments, causing the molecular chains to gradually break, resulting in powdering and cracking of the sealant surface. The tiny fragments (shavings) fall off with the sprayed water. Therefore, the filter plate 22 is used to filter these shavings, and then the sprayed water is reused.

[0044] It is important to note that the spray water should be replaced every three uses, as it is not always recyclable. This is because the ion concentration in the water increases with the number of times it is recycled. According to tests, the ion concentration in the spray water often exceeds the standard after three uses, causing the sealant to age faster or slower than expected, which in turn affects the accuracy of the test on the weather resistance of the silicone sealant.

[0045] Therefore, the spray water needs to be drained and replaced after three uses. So, the personnel open the drain pipe 6 to drain the water at the bottom of the detection device box 1. Of course, before draining, the personnel need to open the drain plate 29. The output end of the second motor 25 drives the screw 23 to rotate, so that the moving plate 26 moves along the screw 23 outside the two guide rods 24.

[0046] At this time, the moving plate 26 will drive the scraper 28 to move, and the impurities on the surface of the filter plate 22 will be discharged through the discharge plate 29. At the same time, the moving plate 26 will also drive the brush 27 to move, so that the brush 27 will clean the inside of the filter holes of the filter plate 22. The cleaned impurities will also fall into the water at the bottom of the detection device housing 1, and then the discharge pipe 6 will be opened to discharge the water.

[0047] Then the water in water tank 16 is reused to simulate rainfall by spraying, and then the new spray water is repeatedly recycled and reused.

[0048] It should be further noted that the length of the brush 27 is greater than the thickness of the filter plate 22, and because of its flexibility, the brush 27 will penetrate the filter holes to clean the impurities inside the filter holes when it moves.

[0049] A second motor 25 is connected to one side of the housing 1 of the detection device, and the output end of the second motor 25 is connected to one end of the screw 23 for transmission.

[0050] The screw 23 is externally threaded with a movable plate 26. The interior of the movable plate 26 is slidably connected to the exterior of two guide rods 24. A brush 27 is connected to the bottom of the movable plate 26, and a scraper 28 is connected to one side of the movable plate 26.

[0051] A discharge plate 29 is hinged to one side of the detection device housing 1, a door panel 4 is hinged to one side of the detection device housing 1, an observation window 5 is provided on the door panel 4, and a drain pipe 6 is connected to one side of the detection device housing 1.

[0052] The inner top surface of the testing device housing 1 is connected to an ultraviolet lamp 3, and a water supply pipe 18 is placed in the gap of the ultraviolet lamp 3. When simulating sunlight, the ultraviolet lamp 3 is turned on to irradiate the silicone sealant. The ultraviolet lamp 3 is a known technology, and those skilled in the art can and should understand its specific function and structure, so it will not be described in detail here. At the same time, placing the water supply pipe 18 in the gap of the ultraviolet lamp 3 can prevent the water supply pipe 18 from interfering with the irradiation of the ultraviolet lamp 3.

[0053] When using this utility model:

[0054] First, when conducting weather resistance testing on silicone sealant, personnel open door panel 4 and place the prepared material (silicone sealant evenly applied between two glass panes) onto the placement rack 7. Then, door panel 4 is closed, and the testing device is controlled via the main control unit 2. In a simulated environment where the silicone sealant is exposed to both sunlight and high temperatures, ultraviolet lamp 3 is turned on and heated simultaneously by heating tube 10. At this time, the output of the first motor 15 drives the rotating shaft 13 to rotate, which in turn drives the sprocket 14 to rotate. Several sprockets 14 are connected by a chain drive, causing them to rotate synchronously. Since the sprockets 14 rotate synchronously with the rotating shaft 13, the rotating shaft 13 drives the rotating frame 11 to rotate. It should be noted that the rotating frame 11 has a rotating ring on its exterior, which rotates inside the upper fixed plate 8 when the rotating frame rotates.

[0055] Secondly, by rotating the frame 11 to drive the baffle plate 12 to rotate, the heating tube 10 is exposed, so that the heating tube 10 can quickly increase the temperature inside the detection device housing 1 to meet the requirements of the simulated sun exposure environment; when simulating a rainy environment, in order to prevent water from being sprayed directly onto the heating tube 10, the frame 11 needs to drive the baffle plate 12 to rotate to shield the heating tube 10, so as to avoid water being sprayed directly onto the heating tube 10 and affecting the service life of the heating tube 10;

[0056] Then, in the simulated rainfall environment, the water inside the water tank 16 is transported to the water supply pipe 18 by the first water pump 17, and then sprayed through the nozzle 19 to simulate the rainfall environment. Because the placement frame 7 has several through holes, the sprayed water will reach the bottom of the detection device box 1 through the filter plate 22. After one round of spraying, the second water pump 20 is started to transport the water at the bottom of the detection device box 1 to the recovery pipe 21. Then the recovery pipe 21 will transport the water to the water supply pipe 18, and then spray it through the nozzle 19. In this way, the sprayed water is recycled and reused, reducing the operating cost of the detection device.

[0057] Finally, the spray water needs to be drained and replaced after three uses. Therefore, the water at the bottom of the detection device housing 1 is drained by opening the drain pipe 6. Before draining, personnel need to open the drain plate 29. The output end of the second motor 25 drives the screw 23 to rotate, causing the moving plate 26 to move along the screw 23 outside the two guide rods 24. At this time, the moving plate 26 will drive the scraper 28 to move and discharge the debris on the surface of the filter plate 22 through the drain plate 29. At the same time, the moving plate 26 will also drive the brush 27 to move, so that the brush 27 will clean the inside of the filter holes of the filter plate 22. The cleaned impurities will also fall into the water at the bottom of the detection device housing 1. Then, the drain pipe 6 is opened to drain the water.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
