Description

Technical Field

[0001] The invention relates to the technical field of waterproof detection, and in particular to an ALC board waterproof detection device. Background Art

[0002] As a lightweight wall material widely used in modern buildings, autoclaved aerated concrete board (ALC board for short) has won the favor of the market for its excellent thermal insulation performance, lightweight and high strength characteristics and environmental protection characteristics. However, in practical applications, especially in rainy areas, the waterproof performance of ALC boards has become a key factor affecting the quality and service life of buildings. Therefore, waterproof testing of ALC boards, such as a waterproof performance testing device for ALC exterior wall panels disclosed in application number CN202221818911.1, to ensure that it meets specific waterproof standards is a necessary means to ensure building quality, prevent rainwater leakage, and maintain a dry indoor environment.

[0003] In the prior art, the spray method is a commonly used method to simulate rainfall environment to test the waterproof performance of ALC boards. This method simulates rainfall of different intensities and frequencies by evenly spraying water mist or water droplets on the surface of the ALC board, and observes and records the distribution and penetration of water on the surface of the board. When using the spray method to test the waterproofness of ALC boards, there are significant differences in the water absorption rate, water diffusion capacity and internal structure stability of ALC boards of different thicknesses. Therefore, for thinner boards, it is necessary to appropriately reduce the spray intensity to slow down the water penetration rate, so as to more accurately evaluate its waterproof performance. For thicker boards, it is necessary to appropriately increase the spray intensity to simulate the impact and penetration of stronger rainfall on the board. In actual rainy environments, rainfall intensity varies. For thin ALC panels, if high-intensity rainfall is always used for simulation testing, it is like a thin tile may be penetrated by rain in light rain, but it should be able to work normally in actual light rain. Similarly, for thick ALC panels, if the spray intensity is not enough, it will not be able to simulate the impact and penetration of the panels in extreme weather such as heavy rain, so the tested waterproof performance will not truly reflect its performance in actual harsh environments. Therefore, adjusting the spray intensity according to the thickness of the panel can more accurately simulate the waterproof performance of the ALC panel in various actual rainfall environments.

[0004] However, the prior art lacks a waterproof detection device that can change the rainfall intensity according to the thickness of the plate. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides an ALC board waterproof detection device, which can effectively solve the problem that the prior art cannot change the rainfall intensity according to the thickness of the board when performing waterproof detection on the ALC board by simulating a rainfall environment through a spraying method.

A water storage component 6 is provided inside the detection frame 2, and the water storage component 6 is placed on the side of the slave plywood 5 away from the main plywood 3. A water supply component 7 for supplying water to the water storage component 6 is provided on the top of the fixed seat 1, and an adjustment component 8 for adjusting the water supply efficiency of the water supply component 7 is provided on the top of the detection frame 2; when it is necessary to perform a waterproof test on the sampled plate, the plate is inserted downward between the main plywood 3 and the slave plywood 5, and the elastic force of the spring 4 fixes the plate between the main plywood 3 and the slave plywood 5. At the same time, when the plate moves downward, the side close to the roller brush 10 will contact the roller brush 10, so that the shikonin attached to the roller brush 10 adheres to the side of the plate.

[0019] The water storage assembly 6 includes a water storage plate 61 fixedly mounted on the inner wall of the detection frame 2. The horizontal height of the top wall of the water storage plate 61 is higher than the horizontal height of the top wall of the clamping plate 5. A water storage cavity 62 is opened inside the water storage plate 61. A plurality of groups of nozzles 63 are fixedly mounted on the water storage plate 61 near one side of the clamping plate 5. The nozzles 63 of the same group include a plurality of columns. The inner diameters of the plurality of columns of nozzles 63 of the same group (refer to Figure 4, whose inner diameter determines the flow rate entering the nozzle 63 per unit time, and the maximum inner diameter of the nozzle 63 is less than or equal to the inner diameter of the water outlet hole 65 hereinafter, that is, the inner diameter of the water outlet hole 65 is greater than the nozzle 63 with the maximum inner diameter, which will not affect the maximum flow rate of the nozzle 63) increases in sequence along one direction, and the nozzles 63 with different inner diameters are used to detect plates of different thicknesses. An adjusting plate 64 is slidably mounted on the inner wall of the water storage chamber 62, and the adjusting plate 64 is provided with water outlet holes 65 respectively adapted to each nozzle 63. Two adjusting plates 64 are symmetrically fixedly mounted on one side of the clamping plate 5. A traction rope 66, two traction ropes 66 are movable from one end of the clamping plate 5 to penetrate the detection frame 2 and the side wall of the water storage plate 61 and are fixedly connected to the adjustment plate 64, a winding box 67 is fixedly installed on the inner wall of the water storage plate 61 and away from the traction rope 66, a rotating shaft is rotatably installed inside the winding box 67, a spring is fixedly installed on the outer side of the rotating shaft, and the other end of the spring is fixedly connected to the inner side wall of the winding box 67, a winding rope is fixedly installed on the side of the adjustment plate 64 close to the winding box 67, and the other end of the winding rope is wound around the outer side of the rotating shaft and connected to it During the inspection, water is delivered to the water storage plate 61 through the water delivery assembly 7, and the water in the water storage chamber 62 is sprayed from the corresponding nozzle 63 to the plate fixed between the main splint 3 and the slave splint 5 through the water outlet hole 65. Since the horizontal height of the top wall of the water storage plate 61 is higher than the horizontal height of the top wall of the slave splint 5, the water sprayed from the nozzle 63 can fall on the surface of the plate after moving in a parabolic trajectory, so that the plate is completely covered. When the thickness of the sampled plate increases, as the slave splint 5 slides, the slave splint 5 drives the traction rope 66 to adjust the plate 64. Traction causes the water outlet 65 to move from the nozzle 63 with a small aperture to the nozzle 63 with a large aperture, that is, the water in the water storage chamber 62 is sprayed out through the required nozzle 63. At the same time, under the action of the adjusting component 8, the water delivery rate of the water delivery component 7 to the water storage plate 61 is also increased, thereby increasing the simulated rainfall intensity. When the adjusting plate 64 moves in the direction of the traction rope 66, the adjusting plate 64 drives the rotating shaft and the spring to rotate through the winding rope. When the inspection of the sample plate is completed and it is removed, the adjusting plate 64 can be moved and reset under the action of the spring.

[0020] The water delivery assembly 7 includes a motor 71 fixedly mounted on the top of the fixed seat 1, a magnetorheological fluid coupling 72 fixedly mounted on the output end of the motor 71, a screw pump body 73 fixedly connected to the output end of the magnetorheological fluid coupling 72, a water inlet end of the screw pump body 73 fixedly connected to a water inlet pipe 74, a water outlet end of the screw pump body 73 fixedly connected to a water outlet pipe 75, an end of the water outlet pipe 75 away from the screw pump body 73 fixedly connected to a connecting pipe 76, a plurality of diverter pipes 77 fixedly mounted on the connecting pipe 76, an end of the diverter pipe 77 away from the connecting pipe 76 fixedly connected to the water storage plate 61; the screw in the screw pump body 73 is driven to rotate by the motor 71 and the magnetorheological fluid coupling 72, and then the water is transported to the water storage plate 61 through the water outlet pipe 75, the connecting pipe 76 and the diverter pipe 77.

[0021] Specifically, the adjustment component 8 includes a baffle 81 fixedly mounted on the top of the slave clamp 5, a fixed frame 82 fixedly mounted on the top of the detection frame 2, a sliding rheostat is arranged inside the fixed frame 82, and the sliding rheostat includes a slide 83 slidably mounted on the fixed frame 82, and the end of the slide 83 away from the fixed frame 82 is fixedly connected to the baffle 81, and the sliding rheostat is electrically connected to a DC power supply and constitutes a transmission ratio circuit. When the fixed frame 82 slides toward the water storage plate 61, the resistance of the sliding rheostat in the transmission ratio circuit decreases; when the thickness of the sampled plate increases, the plate is placed between the main clamp 3 and the slave clamp 5, and the slave clamp When sliding, the baffle 81 drives the sliding piece 83 to slide in the direction of the water storage plate 61. When the sliding piece 83 slides in the direction of the water storage plate 61, the effective resistance of the corresponding sliding rheostat decreases, the current increases, and the electromagnetic field strength increases, thereby affecting the state of the magnetorheological fluid inside the magnetorheological fluid coupling 72, that is, the viscosity of the magnetorheological fluid increases due to the increase of the electromagnetic strength, thereby increasing the bonding strength between the motor 71 and the screw pump body 73, and further improving the water pumping efficiency of the screw pump body 73, so that the water delivery flow rate can be adapted to the corresponding nozzle 63, thereby achieving the effect of increasing the aperture of the nozzle 63 and the water delivery flow rate at the same time.

[0022] A water tank 11 is fixedly installed on the top of the fixing base 1, and the end of the water inlet pipe 74 away from the screw pump body 73 is fixedly connected to the water tank 11. The detection frame 2 and the water tank 11 are fixedly connected through the return pipe 12, and the horizontal height of the return pipe 12 close to the detection frame 2 is higher than the horizontal height of the return pipe 12 close to the water tank 11. The water sprayed onto the surface of the plate through the nozzle 63 will fall to the inner bottom wall of the detection frame 2 and flow into the water tank 11 through the return pipe 12, and then flow out of the screw pump body 73 through the water inlet pipe 74, so that the water during detection is recycled and water resources are saved.

[0023] The working principle of this device is as follows: 1. When it is necessary to conduct waterproof test on the sampled plate, the plate is inserted downward between the main plate 3 and the slave plate 5, and the elastic force of the spring 4 is used to fix the plate between the main plate 3 and the slave plate 5. At the same time, when the plate moves downward, the side close to the roller brush 10 will contact the roller brush 10, so that the shikonin attached to the roller brush 10 adheres to the side of the plate. After the sampled plate is fixed, the motor 71 and the magnetorheological fluid coupling 72 drive the screw in the screw pump body 73 to rotate, and then the water is transported to the water storage plate 61 through the outlet pipe 75, the connecting pipe 76 and the shunt pipe 77. The water in the water storage chamber 62 will be sprayed from the corresponding nozzle 63 through the outlet hole 65 to the plate fixed between the main plate 3 and the slave plate 5. If water penetrates through the plate to the side of the plate principle water storage plate 61 during the test, the water will react with shikonin to show red or purple. The inspector can observe this phenomenon through the transparent side wall of the detection frame 2, and then judge whether the permeability of the plate meets the standard; 2. When the thickness of the sampled plate increases, as the slave clamp 5 slides, the slave clamp 5 drives the traction rope 66 to pull the adjustment plate 64, so that the water outlet 65 moves in the direction of the large-aperture nozzle 63, that is, the water in the water storage chamber 62 is sprayed out through the required nozzle 63, and when the slave clamp 5 slides, the baffle 81 drives the sliding piece 83 to slide in the direction of the water storage plate 61. When the sliding piece 83 slides in the direction of the water storage plate 61, the effective resistance of the corresponding sliding rheostat decreases, the current increases, and the electromagnetic field strength increases, thereby affecting the state of the magnetorheological fluid inside the magnetorheological fluid coupling 72. That is, the viscosity of the magnetorheological fluid will increase due to the increase of electromagnetic intensity, thereby increasing the bonding strength between the motor 71 and the screw pump body 73, and then improving the water pumping efficiency of the screw pump body 73, so that the water flow rate can be adapted to the corresponding nozzle 63, thereby achieving the effect of increasing the aperture of the nozzle 63 and the water flow rate at the same time, so that the simulated rainfall intensity is increased, and when the adjustment plate 64 moves in the direction of the traction rope 66, the adjustment plate 64 also drives the rotating shaft and the spring to rotate through the winding rope. When the inspection of the sample plate is completed and removed, the adjustment plate 64 can be moved and reset under the action of the spring.

[0024] It should be noted that the number of nozzles 63 in each group determines the thickness of the plate to be tested. Figure 4 There are three columns in each group of nozzles 63, so that three types of thicknesses of plates can be tested. The moving distance of the adjustment plate 64 corresponds to the thickness of the plate, that is, each time the plate is fixed, the adjustment plate 64 moves to connect the water outlet 65 with the nozzles 63 at the corresponding positions, and there is no misalignment. The positions of two adjacent columns of nozzles 63 in each group are preset to achieve normal operation.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
