Description

Technical Field

[0001] The utility model belongs to the technical field of engineering detection, and in particular relates to a waterproof detection device for a building exterior wall insulation board. Background Art

[0002] Insulation board is a rigid foam plastic board made of polystyrene resin and extruded by heating. Its function is to insulate the exterior wall of the building to reduce heat exchange and save energy. During the production process of insulation board, the waterproof performance of the insulation board needs to be tested.

[0003] A Chinese patent with publication number CN215574528U discloses an inorganic composite polystyrene Class A insulation board waterproof testing device, which includes a water storage tank, the upper end of which is connected to a water inlet pipe, a test box fixedly installed at the lower end of the water storage tank, a humidity sensor fixedly installed at the lower end of the test box, an insulation board connected to the top of the test box, and a pressure cover tightly installed on the upper end of the insulation board. The above scheme uses the pressure cover to fix the insulation board and ensure the sealing of the insulation board and the test box, so as to avoid water leakage at the installation point of the insulation board and the test box affecting the measurement results.

[0004] During use of the above scheme, the insulation board needs to be cut before the experiment begins. The edges of the insulation board are required to protrude from the orthographic projection surface inside the test box and be located within the orthographic projection surface inside the pressure cover. The cutting accuracy requirements are high, the operation is complicated, and the detection efficiency is affected. Utility Model Content

[0005] The utility model aims to provide a waterproof detection device for building exterior wall insulation boards, so as to solve the problem that the operation of the above-mentioned solution is relatively complicated and affects the detection efficiency.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A waterproof detection device for building exterior wall insulation boards includes a box body, a test box, a pressure plate and a lifting mechanism, the box body has a accommodating cavity, the front side of the accommodating cavity is provided with an opening, the top of the accommodating cavity is connected to a water inlet pipe, the test box is fixedly arranged at the bottom of the accommodating cavity below the water inlet pipe, and the top of the test box is open, a humidity sensor is arranged in the test box, the pressure plate is arranged in the accommodating cavity and located above the test box, and the pressure plate has a passage running through from top to bottom, and the lifting mechanism is arranged in the accommodating cavity and can drive the pressure plate to move up and down.

[0008] The principle and effect of this technical solution:

[0009] The insulation board to be tested is placed on the top of the test box through the opening so that the insulation board covers the test box. The pressure plate is lowered by the lifting mechanism so that the pressure plate presses the insulation board. At this time, the insulation board also presses the top of the test box to form a closed space inside the test box. Water is poured to the top of the insulation board through the water inlet pipe, and the humidity inside the test box is detected by the humidity sensor to judge the waterproofness of the insulation board.

[0010] Through the above arrangement, the insulation board is pressed by the pressing plate, and only the orthographic projection of the insulation board is required to cover the test box. There is no need to accurately cut the insulation board, which simplifies the operation steps and improves work efficiency.

[0011] In the utility model, the lifting mechanism includes two screws rotatably inserted in the accommodating cavity, the two screws are respectively located on the left and right sides of the test box, and a slider is provided on the outside of the screw. The side wall of the slider is slidably abutted against the inner wall of the accommodating cavity, and connecting rods are fixedly provided at the left and right ends of the top of the pressure plate, and the two connecting rods are respectively connected to the bottom of the two sliders.

[0012] In the utility model, it also includes a driving mechanism, which includes a motor, a pulley and a transmission belt. The motor is fixedly arranged on the rear side of the box body. The pulleys are arranged in three numbers and are respectively fixedly arranged on the output end of the motor and the top of the two screws. The transmission belt is wound around the three pulleys.

[0013] The principle and effect of this technical solution:

[0014] The starting motor drives the pulley fixed at the output end of the motor to rotate, and drives the other two pulleys to rotate through the transmission belt, thereby driving the two screws to rotate at the same time. Because the side wall of the slider slides against the inner wall of the accommodating chamber, the inner wall of the accommodating chamber prevents the slider from rotating. The slider moves up and down with the rotation of the screw, thereby driving the pressure plate to move up and down.

[0015] Through the above arrangement, the two sliders can be driven to move the same distance vertically at the same time, thereby achieving the purpose of raising and lowering the pressure plate and preventing the pressure plate from tilting, thereby ensuring that the pressure plate can press the insulation board tightly.

[0016] In the utility model, a mounting groove is arranged in the sliding block, a connecting rod is slidably inserted in the mounting groove, a tension spring is sleeved outside the connecting rod in the mounting groove, and the tension spring connects the bottom of the mounting groove and the top of the connecting rod.

[0017] The principle and effect of this technical solution:

[0018] After the pressure plate presses the insulation board, if the slider is further lowered, the slider will move downward relative to the connecting rod and stretch the tension spring, making it elastic.

[0019] Through the above arrangement, on the one hand, it can prevent the pressing plate from damaging the insulation board, and on the other hand, it can prevent the pressing plate from detaching from the insulation board during the experiment, thereby ensuring the accuracy of the test results.

[0020] In the utility model, a vertical rod is fixedly provided on the bottom surface of the inner cavity of the test box, an insertion rod is fixedly provided on the bottom of the humidity sensor, the insertion rod is slidably inserted on the top of the vertical rod, and a compression spring is provided inside the vertical rod below the insertion rod.

[0021] The principle and effect of this technical solution:

[0022] Place the insulation board on the top of the humidity sensor. At this time, the insulation board is located above the test box. The pressure plate will push the insulation board downward during the descent process until the insulation board abuts against the top of the test box. At this time, the humidity sensor moves downward and pushes the insertion rod to compress the compression spring. The compression spring pushes the humidity sensor against the bottom surface of the insulation board.

[0023] Through the above settings, the humidity sensor is kept in close contact with the bottom surface of the insulation board during the detection process, thereby improving the detection sensitivity.

[0024] In the utility model, a drainage pipe is provided in communication with the bottom of the inner side wall of the box body.

[0025] In the utility model, the bottom surface of the inner cavity of the test box is higher than the bottom surface of the accommodating cavity, and a drainage hole is arranged at the bottom of the inner wall of the test box, and a plug is inserted in the drainage hole.

[0026] The principle and effect of this technical solution:

[0027] The water on the top of the insulation board will flow into the bottom of the accommodating cavity after overflowing the pressure plate and be discharged through the drain pipe. When the waterproof ability of the insulation board is poor, the water on the top of the insulation board will penetrate into the inner cavity of the test box. After the test is completed, the plug is removed and the water in the inner cavity of the test box flows out from the drain hole.

[0028] Through the above-mentioned arrangement, the moisture in the accommodating chamber and the inner cavity of the test box can be discharged, thereby preventing the residual moisture in the inner cavity of the test box from affecting the accuracy of the next detection. At the same time, the bottom surface of the inner cavity of the test box is set to be higher than the bottom surface of the accommodating chamber, which can prevent the moisture in the accommodating chamber from infiltrating into the inner cavity of the test box.

[0029] In the utility model, the front wall of the box body is provided with slots for inserting baffles below the opening and on both sides. Through the above arrangement, it is convenient for the staff to close the opening and prevent water from splashing out of the opening. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] As attached Figure 1-4 As shown, the utility model discloses a waterproof detection device for building exterior wall insulation board, including a box body 10, a test box 20, a pressing plate 30 and a lifting mechanism, the box body 10 has a accommodating chamber 11, the front side of the accommodating chamber 11 is provided with an opening 12, the top of the accommodating chamber 11 is connected to a water inlet pipe 13, the test box 20 is fixedly arranged at the bottom of the accommodating chamber 11 below the water inlet pipe 13, and the top of the test box 20 is open, a humidity sensor 21 is arranged in the test box 20, the pressing plate 30 is arranged in the accommodating chamber 11 and is located above the test box 20, and the pressing plate 30 has a channel 31 that passes through from top to bottom, and the lifting mechanism is arranged in the accommodating chamber 11, and can drive the pressing plate 30 to move up and down.

[0037] In this embodiment, the lifting mechanism includes two screws 41 rotatably inserted in the accommodating cavity 11, and the two screws 41 are respectively located on the left and right sides of the test box 20. A slider 42 is provided on the outside of the screw 41. The side wall of the slider 42 is slidably abutted against the inner wall of the accommodating cavity 11. Connecting rods 32 are fixedly provided at the left and right ends of the top of the pressure plate 30, and the two connecting rods 32 are respectively connected to the bottom of the two sliders 42.

[0038] In this embodiment, a driving mechanism is also included, which includes a motor 51, a pulley 52 and a transmission belt 53. The motor 51 is fixedly arranged on the rear side of the box body 10. The pulleys 52 are arranged in three numbers, which are respectively fixedly arranged on the output end of the motor 51 and the tops of the two screws 41. The transmission belt 53 is wound around the three pulleys 52.

[0039] In this embodiment, a mounting groove 421 is provided in the slider 42 , and the connecting rod 32 is slidably inserted in the mounting groove 421 . A tension spring 422 is sleeved outside the mounting groove 421 of the connecting rod 32 , and the tension spring 422 connects the bottom of the mounting groove 421 and the top of the connecting rod 32 .

[0040] In this embodiment, a vertical rod 22 is fixedly provided on the bottom surface of the inner cavity of the test box 20, and an insertion rod 23 is fixedly provided at the bottom of the humidity sensor 21. The insertion rod 23 is slidably inserted into the top of the vertical rod 22, and a compression spring 24 is provided in the vertical rod 22 below the insertion rod 23.

[0041] In this embodiment, a drain pipe 15 is provided at the bottom of the inner wall of the box body 10 .

[0042] In this embodiment, the bottom surface of the inner cavity of the test box 20 is higher than the bottom surface of the accommodating cavity 11 , and a drainage hole 25 is provided at the bottom of the inner wall of the test box 20 , and a plug 251 is inserted into the drainage hole 25 .

[0043] In this embodiment, the front wall of the box body 10 is provided with slots 14 for inserting baffles below the opening 12 and on both sides thereof.

[0044] The specific implementation process is as follows:

[0045] The insulation board 60 to be tested is placed on the top of the test box 20 through the opening 12, so that the insulation board 60 covers the test box 20, and the pressing plate 30 is lowered by the lifting mechanism so that the pressing plate 30 presses the insulation board 60. At this time, the insulation board 60 also presses the top of the test box 20, so that a closed space is formed inside the test box 20, and water is poured to the top of the insulation board 60 through the water inlet pipe 13. The humidity inside the test box 20 is detected by the humidity sensor 21, and then the waterproofness of the insulation board 60 is judged.

[0046] The starting motor 51 drives the pulley 52 fixed at the output end of the motor 51 to rotate, and drives the other two pulleys 52 to rotate through the transmission belt 53, thereby driving the two screws 41 to rotate at the same time. Because the side wall of the slider 42 slides against the inner wall of the accommodating chamber 11, the inner wall of the accommodating chamber 11 prevents the slider 42 from rotating, and the slider 42 moves up and down with the rotation of the screw 41, thereby driving the pressure plate 30 to move up and down.

[0047] After the pressing plate 30 presses the heat preservation plate 60 , if the slider 42 is further lowered, the slider 42 will move downward relative to the connecting rod 32 and stretch the tension spring 422 to make it have elastic force.

[0048] The insulation board 60 is placed on the top of the humidity sensor 21. At this time, the insulation board 60 is located above the test box 20. The pressure plate 30 will push the insulation board 60 downward during the descending process until the insulation board 60 abuts against the top of the test box 20. At this time, the humidity sensor 21 moves downward and pushes the insertion rod 23 to compress the compression spring 24. The compression spring 24 pushes the humidity sensor 21 against the bottom surface of the insulation board 60.

[0049] The water on the top of the insulation board 60 will flow into the bottom of the accommodating cavity 11 after overflowing the pressing plate 30, and will be discharged through the drain pipe 15. When the waterproof ability of the insulation board 60 is poor, the water on the top of the insulation board 60 will penetrate into the inner cavity of the test box 20. After the test is completed, the plug 251 is removed, and the water in the inner cavity of the test box 20 flows out from the drain hole 25.
