In addition, it is not convenient to detect the influence of different temperatures on the waterproof performance of waterproof materials. Water detection cannot detect the small holes on the surface of waterproof materials, resulting in inaccurate detection data.

[0005] Therefore, the present invention provides a detection device for building waterproof materials. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] Embodiment 1

[0025] Existing detection equipment is used to support waterproof materials, pour water directly onto the waterproof materials, and observe the water permeability of the waterproof materials. This detection method requires long-term observation by staff and is not convenient for detecting the influence of different temperatures on the waterproof performance of waterproof materials.

[0026] As Figure 1 shown, a detection device for building waterproof materials includes a bottom plate 1; a waterproof material body 2, and the waterproof material body 2 is placed on the top of the bottom plate 1; a test paper 3, and the test paper 3 is placed at the bottom of the waterproof material body 2 for detecting the test liquid that penetrates to the bottom of the waterproof material body 2.

[0027] As Figures 1 to 4 shown, a detection component 4 is provided on the top of the waterproof material body 2. The detection component 4 includes a detection cylinder 41. A vertical pipe 44 is arranged in the middle of the detection cylinder 41. A plurality of partition plates 45 are symmetrically and fixedly connected to the side wall of the vertical pipe 44. One side of each partition plate 45 away from the vertical pipe 44 is fixedly connected to the inner wall of the detection cylinder 41. There are four partition plates 45. The inner part of the detection cylinder 41 is divided into four cavities by the partition plates 45. A constant temperature heater 42 and a semiconductor refrigeration sheet 43 are respectively fixedly connected to the side walls of the two cavities opposite to the two long sides of the bottom plate 1.

[0028] During operation, first lay the test strip 3 flat on the bottom plate 1, then place the waterproof material body 2 to be tested above the test strip 3, and then place the detection component 4 on top of the waterproof material body 2. Then, inject the detection liquid into the cavity connected to the constant temperature heater 42 and the semiconductor refrigeration sheet 43. The detection liquid is normal temperature clear water. After that, use the constant temperature heater 42 to raise the temperature of the detection liquid in the corresponding cavity to the specified temperature and keep it constant at this temperature. The waterproof material body 2 on this side comes into contact with the heated detection liquid. Similarly, use the semiconductor refrigeration sheet 43 on the other side to lower the temperature of the detection liquid in the corresponding cavity to the specified temperature and keep the temperature constant. The waterproof material body 2 on this side comes into contact with the cooled detection liquid and maintains for a certain period of time. The test strip 3 absorbs the detection liquid that penetrates from the top of the waterproof material body 2. A humidity sensor is inlaid and connected on the bottom plate 1. The humidity sensor detects the humidity at the corresponding position of the test strip 3. The humidity sensor is connected to an external display, and the humidity value is intuitively displayed on the display. If the test strip 3 remains dry, it indicates that the waterproof effect of the waterproof material body 2 is good. If the humidity sensor detects an increase in the humidity of the test strip 3, it indicates that the waterproof effect of the waterproof material body 2 is poor. The waterproof effect of the waterproof material body 2 can be intuitively observed through the size of the humidity value, and the operation is simple, reducing the labor intensity. Moreover, by controlling the temperature of the detection liquid, the influence of different temperatures on the waterproof effect of the waterproof material body 2 can be detected. In addition, multiple groups of detection components 4 are set at the same time, and the temperature of the detection liquid in each group of detection components 4 is controlled to be different, so that multiple experiments can be carried out simultaneously to save the detection time and improve the detection efficiency.

[0029] Such as Figure 1 、 Figure 2As shown, first sealing plates 46 are respectively arranged at the bottom parts of two cavities opposite to the long sides on both sides of the bottom plate 1. The first sealing plates 46 are magnetic plates and can adsorb to the detection cylinder 41 and the partition plate 45, so as to improve the sealing performance between the first sealing plates 46 and the detection cylinder 41 and the partition plate 45, and prevent the detection liquid from leaking out from the gaps at adjacent positions. The first sealing plates 46 are adapted to the inner contour of the cavity. The arc-shaped edges of the first sealing plates 46 are attached to the inner wall of the detection cylinder 41. The two sides at the top of the first sealing plates 46 are respectively attached to the bottom of the partition plate 45. A first through hole 412 is provided in the middle of the first sealing plates 46. A first rotating block 47 is provided at the bottom of the vertical pipe 44. The two first sealing plates 46 on both sides are symmetrically and fixedly connected to the sides of the first rotating block 47. The first sealing plates 46 can rotate inside the detection cylinder 41. A leakage plate 413 is attached to the top of the first sealing plates 46. Second through holes 414 are provided at the edges of the leakage plate 413. The top of the first sealing plates 46 blocks the second through holes 414, thereby preventing the detection liquid from flowing out from the bottom of the cavity. Then, the waterproof material body 2 can be drawn out from the bottom of the detection assembly 4 to facilitate the replacement of a new waterproof material body 2 for the next detection. A connecting rod 48 is rotatably connected in the middle of the vertical pipe 44. A second rotating block 49 is provided at the top of the vertical pipe 44. The first rotating block 47 and the second rotating block 49 are respectively fixed at both ends of the connecting rod 48. The top of the detection cylinder 41 is fixedly connected to a fixing plate 410. The top of the fixing plate 410 is fixedly connected to a motor 411. The output shaft of the motor 411 penetrates through the fixing plate 410 and is fixedly connected to the top of the second rotating block 49. The lower end surfaces of the detection assembly 4 are on the same horizontal plane. The lower end surfaces of the detection cylinder 41, the longer partition plate 45 at the bottom, the first rotating block 47 and the first sealing plates 46 in the detection assembly 4 are flush, so that the bottom end of the detection assembly 4 can be closely attached to the top end of the waterproof material body 2 to prevent the detection liquid from leaking.

[0030] Place the detection assembly 4 on the top of the waterproof material body 2. The bottom ends of the detection cylinder 41 and the first sealing plates 46 are closely attached to the top of the waterproof material body 2. After injecting the detection liquid into the cavity connected with the constant temperature heater 42 and the semiconductor refrigerating sheet 43, start the motor 411. The motor 411 drives the second rotating block 49, the connecting rod 48 and the first rotating block 47 to rotate through the output shaft, and then drives the two first sealing plates 46 on both sides to rotate inside the detection cylinder 41, releasing the blockage of the second through holes 414 by the first sealing plates 46, so that the detection liquid in the cavity of the constant temperature heater 42 and the semiconductor refrigerating sheet 43 contacts the waterproof material body 2 and detects the waterproof material body 2. The waterproof effect of the waterproof material body 2 at different temperatures is simple to operate and reduces the working intensity of the staff.

[0031] As Figure 1 , Figure 2As shown in the figure, lifting components 5 are arranged on both sides of the bottom plate 1. The detection component 4 is lifted by the lifting components 5 to facilitate the replacement of the waterproof component. The lifting component 5 includes columns 51 fixed to the top edge of the bottom plate 1. Double-layer clamping plates 52 are symmetrically and slidably connected to the two columns 51. Installation components 6 are respectively arranged at both ends of the fixing plate 410. The installation component 6 is connected to the clamping plate 52. Hydraulic cylinders 53 are fixedly connected to the bottoms of both clamping plates 52. The bottoms of the hydraulic cylinders 53 are fixed to the top of the bottom plate 1. A limiting plate 55 is fixedly connected to the top end of the column 51. The limiting plate 55 limits the clamping plate 52 to prevent the clamping plate 52 from sliding out of the outer wall of the column 51.

[0032] The fixing plate 410 and the clamping plate 52 are connected together through the installation component 6. Then, the hydraulic cylinder 53 is started. The hydraulic cylinder 53 drives the clamping plate 52 to move up and down. Through the hydraulic cylinder 53, the detection component 4 can be driven to move downwards through the fixing plate 410, so that the detection component 4 can be closely attached to the waterproof material body 2, further avoiding the leakage of the detection liquid. The hydraulic cylinder 53 drives the detection component 4 to move upwards through the fixing plate 410, so that the detection component 4 is separated from the waterproof material body 2, and the waterproof material body 2 is no longer squeezed, facilitating the quick extraction and replacement of the waterproof material body 2.

[0033] As Figure 3 shown in the figure, the installation component 6 includes insertion blocks 63 symmetrically arranged at both ends of the fixing plate 410. The insertion blocks 63 are inserted into the middle of the clamping plate 52. A movable plate 64 is fixedly connected to the side of the insertion block 63. The movable plate 64 is slidably arranged in the chute 62 opened at both ends of the fixing plate 410. A vertical plate 65 is fixedly connected to the end of the movable plate 64 away from the insertion block 63. The chute 62 is set in an L shape. The movable plate 64 and the vertical plate 65 are respectively adapted to the chute 62 to limit the movement range of the movable plate 64, so that the movable plate 64 can only move linearly along the direction of the chute 62. A handle 7 is fixedly connected to the middle of the top of the fixing plate 410. A movable frame 61 is slidably inserted into the top of the handle 7. The movable frame 61 is arranged in a U shape. A fourth through hole 69 is opened on the side wall of the handle 7. A pull rope 66 is arranged in the fourth through hole 69. One end of the pull rope 66 is fixed to the side of the vertical plate 65, and the other end of the pull rope 66 is fixed to the bottom of the movable frame 61. A spring 68 is connected between the vertical plate 65 and the handle 7. A guide rod 67 is arranged in the middle of the spring 68. One end of the guide rod 67 is fixed to the side wall of the handle 7, and the other end of the guide rod 67 passes through the sliding hole opened on the vertical plate 65. The position of the spring 68 is limited through the guide rod 67 to make the connection of the spring 68 more stable. A limiting block 54 is fixedly connected to the middle of the clamping plate 52. The limiting blocks 54 are arranged in pairs. The distance between the two limiting blocks 54 is adapted to the width of the insertion block 63. The insertion block 63 is limited by the limiting block 54 to stably connect the insertion block 63 in the middle of the clamping plate 52.

[0034] Grip the handle 7 and press down the movable frame 61 at the same time. The bottom ends on both sides of the movable frame 61 pull down the pull ropes 66, and then the pull ropes 66 pull the vertical plates 65 on both sides to move closer to the middle. The spring 68 is compressed, and the movable plate 64 and the insertion block 63 are pulled by the vertical plates 65 to slide along the chute 62, so that the insertion blocks 63 on both sides move closer to the middle. After that, the insertion blocks 63 can be moved to the position aligned with the middle gap of the clamping plates 52. Then release the movable frame 61. Under the action of the spring 68 rebounding, the insertion blocks 63 are pushed back to their original positions, so that the insertion blocks 63 are inserted into the middle of the clamping plates 52 on both sides, so that the detection assembly 4 can be connected to the clamping plates 52. In addition, the damaged detection assembly 4 can be replaced separately, making the maintenance and repair more convenient.

[0035] The temperature of the detection liquid is increased and decreased to the specified temperature by the constant temperature heater 42 and the semiconductor refrigeration sheet 43, and maintained at this temperature. The detection liquid contacts the waterproof material body 2 for a certain period of time. The detection paper 3 absorbs the detection liquid that penetrates from the top of the waterproof material body 2. The humidity sensor detects the humidity at the corresponding position of the detection paper 3, and the humidity value is intuitively displayed on the display. The waterproof effect of the waterproof material body 2 can be intuitively observed through the size of the humidity value. The operation is simple. The detection assembly 4 is convenient for detecting the waterproof effect of the waterproof material body 2 at different temperatures. The operation is simple, reducing the work intensity of the staff. The temperatures of the detection liquid in multiple groups of detection assemblies 4 are different, so that multiple experiments can be carried out simultaneously to save the detection time and improve the detection efficiency.

[0036] Embodiment 2

[0037] Based on the above embodiment, there is a problem that the small holes on the surface of the waterproof material cannot be detected by water detection, resulting in inaccurate detection data.

[0038] As Figures 4 to 7 shown, a sealing plate 415 is fixedly connected to the top end of each partition plate 45. The outer wall of the sealing plate 415 is fixedly connected to the inner wall of the detection cylinder 41. The sealing plate 415 is provided with a third through hole 418 at the top of the leakage plate 413. Communication grooves 416 are opened at the top ends of two relatively symmetric partition plates 45, and adjacent cavities are connected through the communication grooves 416. Second sealing plates 417 are respectively arranged at the tops of two cavities opposite to the short sides of the bottom plate 1. The second sealing plates 417 are magnetic plates and can be adsorbed to the sealing plate 415. The arc-shaped sides of the second sealing plates 417 are attached to the inner wall of the detection cylinder 41, and the bottom of the second sealing plates 417 is attached to the top of the sealing plate 415. The two second sealing plates 417 are symmetrically fixedly connected to the sides of the second rotating block 49.

[0039] Place the detection component 4 on top of the waterproof material body 2. Inject the detection liquid into the cavity connected to the constant temperature heater 42 and the semiconductor refrigeration sheet 43 through the third through hole 418. After the injection of the detection liquid is completed, start the motor 411. The motor 411 drives the second rotating block 49, the connecting rod 48, and the first rotating block 47 to rotate through the output shaft, and then drives the second sealing plates 417 on both sides to rotate inside the detection cylinder 41. The second sealing plates 417 block the third through hole 418, making the detection cylinder 41 form a closed space. The detection liquid in the cavity of the constant temperature heater 42 and the semiconductor refrigeration sheet 43 rises and falls. The detection liquid contacts the waterproof material body 2. The constant temperature heater 42 maintains a certain temperature for a long time to generate water vapor. Then, the water vapor can simulate a humid and hot environment. The water vapor rises through the communication groove 416 and enters the connected cavity inside, making the water vapor in the connected cavity gradually increase. The formed water vapor contacts the waterproof material body 2. The higher the temperature, the greater the gas permeability coefficient, because the increase in temperature will increase the kinetic energy of gas molecules, making it easier for them to pass through the film or medium. Similarly, the temperature of the detection liquid in the corresponding cavity on the other side is reduced to the specified temperature by the semiconductor refrigeration sheet 43. The semiconductor refrigeration sheet 43 maintains a certain temperature for a long time to generate moisture, and the moisture can simulate a humid environment. The formed moisture contacts the waterproof material body 2. When the temperature decreases, the molecular gap will become larger and the osmotic pressure will increase, so as to better detect the waterproof performance of the material. The particle size of air molecules is much smaller than that of water molecules, so the gas can detect smaller leakage holes. The water vapor and moisture are between hot and cold. The thermal energy inside the constant temperature heater 42 and the cold energy of the semiconductor refrigeration sheet 43 are transferred to the adjacent cavity through the partition plate 45, forming a temperature difference. The increase in the temperature difference will increase the impact frequency of gas molecules on the film or medium, thus increasing the penetration rate. Therefore, the greater the temperature difference, the greater the gas permeability coefficient, so as to more accurately detect the data of the waterproof material and improve the detection accuracy. At the same time, water detection and gas detection are carried out simultaneously, improving the detection work efficiency, ensuring the waterproof authenticity of the waterproof material, and ensuring the qualified quality of the waterproof material.

[0040] The third through hole 418 is blocked by the second sealing plate 417, making the detection cylinder 41 form a closed space. The semiconductor refrigeration sheet 43 maintains a certain temperature for a long time to generate moisture. The particle size of air molecules is much smaller than that of water molecules, so the gas can detect smaller leakage holes, accurately detect the data of the waterproof material, and improve the detection accuracy. At the same time, water detection and gas detection are carried out simultaneously, improving the detection work efficiency, ensuring the waterproof authenticity of the waterproof material, and ensuring the qualified quality of the waterproof material.

[0041] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
