Description

Technical Field

[0001] The invention relates to the technical field of thermal insulation boards, in particular to a thermal insulation board permeability detection device. Background Art

[0002] Insulation board is a board used for insulation of buildings. It is made of polystyrene resin as the main material, other raw materials and polymers, and is heated and mixed while injecting catalysts, and then extruded and pressed to form a rigid foam plastic board. Insulation board has moisture-proof and waterproof properties, so it is widely used in the field of building insulation to improve the insulation performance and energy-saving effect of buildings. Insulation board plays a waterproof role for the exterior wall of the building, so it is very important to test the penetration performance of the insulation board;

[0003] However, the existing testing equipment has a relatively simple structure, and the accuracy of the test results is low. In addition, when the current testing equipment is conducting a spraying experiment, the spraying structure is basically fixed, and the spraying range is limited. Some places on the insulation board cannot be completely sprayed with water, which has a certain impact on the test results.

[0004] Or, as provided by publication number "CN112033610A", a waterproof testing device for building insulation boards based on 5G technology can deliver the insulation board into the interior of the test box through the set plate inlet, and through the set pressure plate, when the electric push rod is extended, the pressure plate can be pushed downward to press the insulation board, so as to seal the interior of the test box, and the first and second pumping pumps can be set to pump the water drawn out of the water tank back into the water tank through the first pumping pump, and the water flows into the test box and flows above the insulation board for testing, and if there is any leakage, it can be detected by the humidity sensor;

[0005] However, when the device is in use, although it can test the waterproofness of the insulation board by squeezing water out of the sponge and making it fall on the insulation board, this method cannot simulate a real rainy environment, resulting in a large difference between the water spray test and actual use, and cannot accurately evaluate the water permeability of the insulation board.

[0045] For example 3, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7The detection component 4 includes a placement plate 41, and the two sides of the placement plate 41 are respectively in contact with the inner walls of the two sides of the detection box 1. A water-permeable groove 42 is provided on the placement plate 41, and a humidity sensor 43 is provided in the water-permeable groove 42. A sealing ring 44 for sealing the connection between the placement plate 41 and the insulation plate is also provided on the top of the placement plate 41. The inner walls of the two sides of the detection box 1 are respectively provided with limited sliding grooves 13, and the two sides of the placement plate 41 are respectively fixedly connected with sliding shafts 45. The two sliding shafts 45 are respectively slidably connected to the adjacent limited sliding grooves 13, and a driving gear 46 is also installed at one end of one of the sliding shafts 45 away from the placement plate 41. The adjacent limited sliding groove 13 is provided with teeth meshing with the driving gear 46 inside, and the driving gear 46 is also provided with a first servo at one end away from the placement plate 41. Motor 47, the output end of the first servo motor 47 is fixed to the driving gear 46 through a coupling, electric push rods 14 are also provided on the inner walls on both sides of the detection box 1, and the facing surfaces of the two electric push rods 14 are provided with blocks 15, and the bottoms of the two blocks 15 are in contact with the top of the placement plate 41. The auxiliary fixing component 5 includes an L-shaped fixing plate 51, and the L-shaped fixing plate 51 is fixedly installed on one side of the top of the placement plate 41. The L-shaped fixing plate 51 is provided with a sliding groove 52, and the sliding groove 52 is rotatably connected with a first rotating screw 53, and the first rotating screw 53 is threadedly connected with a pressing plate 54. A second servo motor 55 is provided inside the placement plate 41 close to the L-shaped fixing plate 51, and the output end of the second servo motor 55 is fixed to the first rotating screw 53 through a coupling;

[0046] When in use, first place the insulation board on the placement board 41, and make the bottom of the insulation board close to the sealing ring 44 on the placement board 41, and seal the placement board 41 and the insulation board through the sealing ring 44, start the second servo motor 55, and make the second servo motor 55 drive the first rotating screw 53 to rotate, so that the pressing plate 54 slides on the first rotating screw 53 along the sliding groove 52, and adjust the pressing plate 54 to be close to the insulation board on the placement board 41, and press the insulation board through the pressing plate 54, so that the insulation board is firmly fixed on the placement board 41;

[0047] Simultaneously start the two electric push rods 14, so that the two electric push rods 14 drive the two clamping blocks 15 to move toward the direction of the insulation board on the placement plate 41, and make the two clamping blocks 15 abut against the two sides of the insulation board respectively, and further fix the insulation board through the two clamping blocks 15;

[0048] During the water spray test, if water seepage occurs in the insulation board, the seeped water will fall into the water permeable groove 42 and can be detected by the humidity sensor 43;

[0049] When the water spray test is completed, the second servo motor 55 is started again, so that the second servo motor 55 drives the pressure plate 54 to move upward, so that the pressure plate 54 is no longer fixed to the insulation board, and the first servo motor 47 is started at this time, so that the first servo motor 47 drives the driving gear 46 to rotate. Since the driving gear 46 is meshed with the teeth in the limiting slide groove 13, when the driving gear 46 rotates, it will drive the placement plate 41 to move along the trajectory of the limiting slide groove 13, so that the placement plate 41 is turned over to a vertical state. At the same time, since the pressure plate 54 is no longer fixed to the insulation board, the insulation board is now in a suspended state clamped by the two clamping blocks 15;

[0050] When the plate 41 is placed vertically, the immersion assembly 6 is opened, and the two electric push rods 14 are closed at the same time, so that the insulation plate falls downward onto the immersion assembly 6, and the immersion test is performed through the immersion assembly 6.

[0051] Example 4, please refer to Figure 1 , Figure 2 , Figure 8 and Fig. 9 The immersion assembly 6 includes an immersion box 61, which is installed inside the detection box 1. The water inlet end of the immersion box 61 is connected to the water inlet pipe 23, and the water outlet end of the immersion box 61 is connected to the water outlet pipe 24. The other ends of the water inlet pipe 23 and the water outlet pipe 24 are both connected to the water storage tank 2. The water inlet pipe 23 and the water outlet pipe 24 are both provided with micro water pumps. A limiting assembly for limiting the position of the insulation board is also provided in the immersion box 61. A rotating groove 62 is provided on one side of the immersion box 61. The limiting assembly is hinged in the rotating groove 62. The limiting assembly includes a first connecting rod 63. A rotating shaft is provided on the side of the first connecting rod 63 close to the rotating groove 62. The rotating shaft is rotatably connected to the rotating groove 62. A plurality of evenly distributed pressure rods 64 are installed on the side of the first connecting rod 63 away from the rotating groove 62. The immersion box A lifting mechanism is also provided in 61, and the lifting mechanism is provided below the first connecting rod 63. The lifting mechanism includes two second connecting rods 65, and a plurality of lifting rods 66 are installed between the two second connecting rods 65. The lifting mechanism also includes a second rotating screw 69, and the second rotating screw 69 is provided at a corner in the immersion tank 61. A micro motor is provided in the inner wall of the immersion tank 61, and the output end of the micro motor is fixed to the second rotating screw 69 through a coupling, and one end of one of the second connecting rods 65 close to the second rotating screw 69 is threadedly connected to the second rotating screw 69, and the other end of the second connecting rod 65 is installed with a synchronous rack 68, and the end of the first connecting rod 63 close to the synchronous rack 68 is installed with a driven gear 67, and the driven gear 67 is meshed with the synchronous rack 68;

[0052] When conducting the immersion test, first start the micro motor at the bottom of the second rotating screw 69, so that the micro motor drives the second rotating screw 69 to rotate, so that the second connecting rod 65 moves upward under the action of the second rotating screw 69, and the second connecting rod 65 on one side moves through the lifting rod 66 and drives the second connecting rod 65 on the other side to move. When the second connecting rod 65 moves upward, the synchronous rack 68 moves upward at the same time, and drives the driven gear 67 to rotate, so that the driven gear 67 drives the first connecting rod 63 to flip, so that the first connecting rod 63 turns to a vertical state, and at this time the second connecting rod 65 and the lifting rod 66 continue to move upward. The synchronous rack 68 gradually disengages from the driven gear 67, and the lifting rod 66 moves up to catch the insulation board falling down. When the insulation board falls on the lifting rod 66, the micro motor is driven to reverse, so that the second rotating screw 69 drives the second connecting rod 65 to move downward, so that the lifting rod 66 moves downward, driving the insulation board to immerse in the immersion tank 61. At the same time, when the lifting rod 66 passes over the first connecting rod 63, the synchronous rack 68 meshes with the driven gear 67 again, driving the driven gear 67 to rotate in the opposite direction and reset. When the second connecting rod 65 is completely reset, the insulation board is completely immersed in the immersion tank 61 under the limit of the lifting rod 66 and the pressure rod 64.

[0053] At this time, the micro water pump on the water inlet pipe 23 is turned on, and the water in the water storage tank 2 is injected into the immersion tank 61 through the water inlet pipe 23, so that the insulation board is completely immersed in water, and the water absorption of the insulation board is tested;

[0054] After the test is completed, the micro motor is started again to rotate the second rotating screw 69 to drive the second connecting rod 65 to move upward. At this time, the synchronous rack 68 drives the driven gear 67 to flip again, so that the lifting rod 66 and the insulation board can move up smoothly. After moving up, the micro motor is turned off to allow the insulation board to drain water on the lifting rod 66. After ten minutes, the insulation board can be removed from the lifting rod 66 for testing. At the same time, the water in the immersion tank 61 is discharged to the water storage tank 2 through the outlet pipe 24 for recycling.

[0055] The working principle of the present invention is as follows: when the device is needed to detect the insulation board, firstly, the detection box 1 is opened through the cabinet door 11, the insulation board is placed on the placement board 41, and the insulation board is tightly attached to the sealing ring 44, the placement board 41 and the insulation board are sealed by the sealing ring 44, the second servo motor 55 is started, the second servo motor 55 drives the first rotating screw 53 to rotate, the pressing plate 54 is adjusted to be tightly attached to the insulation board on the placement board 41, the insulation board is pressed by the pressing plate 54, and the insulation board is firmly fixed on the placement board 41;

[0056] Simultaneously start the two electric push rods 14, so that the two electric push rods 14 drive the two clamping blocks 15 to move toward the direction of the insulation board on the placement plate 41, and make the two clamping blocks 15 abut against the two sides of the insulation board respectively, and further fix the insulation board through the two clamping blocks 15;

[0057] The water pump 21 is turned on to make the water in the water storage tank 2 flow to the spray pipe 31 through the connecting pipe 22 and spray out through the multiple spray heads 32. At the same time, the driving motor is started to drive the rotating disk 36 to rotate. When the rotating disk 36 rotates, the connecting rod 35 is driven to rotate synchronously at the same time. The cam 34 is pulled to flip through the connecting rod 35, thereby driving the connecting shaft 33 and the spray pipe 31 to flip, so that the connecting shaft 33 and the spray pipe 31 swing left and right, so that the spray heads 32 can better simulate the real rainy environment;

[0058] During the water spray test, if water seepage occurs in the insulation board, the seeped water will fall into the water permeable groove 42 and can be detected by the humidity sensor 43;

[0059] When the water spray test is completed, the second servo motor 55 is started again, so that the second servo motor 55 drives the pressing plate 54 to move upward, so that the pressing plate 54 is no longer fixed to the insulation board. At this time, the first servo motor 47 is started, so that the first servo motor 47 drives the driving gear 46 to rotate, and drives the placement plate 41 to move along the track of the limiting slide groove 13, so that the placement plate 41 is turned over to a vertical state. At the same time, since the pressing plate 54 is no longer fixed to the insulation board, the insulation board is now in a suspended state under the clamping of the two clamping blocks 15;

[0060] When the placement plate 41 is vertical, the micro motor at the bottom of the second rotating screw 69 is started, so that the micro motor drives the second rotating screw 69 to rotate, so that the second connecting rod 65 moves upward under the action of the second rotating screw 69, and the synchronous rack 68 moves upward at the same time, and drives the driven gear 67 to rotate, so that the driven gear 67 drives the first connecting rod 63 to flip, so that the first connecting rod 63 is turned to a vertical state. At this time, the second connecting rod 65 and the lifting rod 66 continue to move upward, and the synchronous rack 68 gradually disengages from the driven gear 67. At the same time, the two electric push rods 14 are closed, so that the insulation board falls downward, and the lifting rod 66 moves upward to catch the insulation board falling downward. When the insulation board falls on the lifting rod 66 After the first connecting rod 63 is raised, the micro motor is driven to reverse, so that the second rotating screw 69 drives the second connecting rod 65 to move downward, so that the lifting rod 66 moves downward, and drives the insulation board to be immersed in the immersion tank 61. At the same time, when the second connecting rod 65 passes over the first connecting rod 63, the synchronous rack 68 is meshed with the driven gear 67 again, driving the driven gear 67 to rotate in the opposite direction and reset. When the second connecting rod 65 is completely reset, the insulation board is completely immersed in the immersion tank 61 under the limit of the lifting rod 66 and the pressure rod 64, and the micro water pump on the water inlet pipe 23 is turned on, and the water in the water storage tank 2 is injected into the immersion tank 61 through the water inlet pipe 23, so that the insulation board is completely immersed in water, and the water absorption of the insulation board is tested;

[0061] After the test is completed, the micro motor is started again to rotate the second rotating screw 69 to drive the second connecting rod 65 to move upward. At this time, the synchronous rack 68 drives the driven gear 67 to flip again, so that the lifting rod 66 and the insulation board can move up smoothly. After moving up, the micro motor is turned off to allow the insulation board to drain on the lifting rod 66. After ten minutes, the insulation board can be taken out from the lifting rod 66 for testing.

[0062] It should be noted that the various devices in this application are common devices in the market, and can be selected according to specific needs during specific use.
