Description

Technical Field

[0001] This invention relates to the field of waterproof testing technology, specifically to a device for testing the waterproof properties of penetrating crystalline concrete based on a humidity sensor. Background Technology

[0002] Traditional methods for testing the waterproofing performance of penetrating crystalline concrete often rely on equipment such as permeability meters, judging performance by observing seepage time or maximum pressure value. This approach has limitations, including strong subjectivity, inability to quantify the internal seepage process, and difficulty in capturing subtle seepage and dynamic changes in crystallization blockage. With the development of sensing technology, humidity sensors can monitor the humidity distribution inside concrete in real time. However, existing devices often suffer from data distortion due to poor sealing and unstable sample fixation, and lack accurate tracking of seepage at different depths. Therefore, there is an urgent need to develop a dedicated device that integrates a humidity sensor array, a sealing clamping mechanism, and a water pressure simulation system to achieve quantitative testing of waterproofing performance and meet the engineering requirements for accurate evaluation of material properties.

[0003] Patent CN218546035U discloses a waterproof testing device for underground building concrete structures. The device includes a base plate with vertical plates fixedly connected to the top of the base plate near both sides. A top plate is fixedly connected to the top of both vertical plates. An electric telescopic rod is installed, which pushes a piston to move, pressurizing the water tank and allowing water to flow more quickly through cracks in the concrete structure to the surface, generating air bubbles. If no cracks are present, no air bubbles are generated, effectively improving testing efficiency and providing a clear view of the test results. Limiting blocks are installed to restrict the installation of the concrete structure, and two clamping blocks further secure it, preventing displacement during subsequent testing and ensuring stable operation.

[0004] However, when using the above-mentioned device, it is difficult to simultaneously simulate real-world damage to the concrete during the process of clamping and limiting the penetrating crystalline concrete. This results in a decrease in the speed of waterproofing testing of penetrating crystalline concrete and affects the efficiency of subsequent tests. Therefore, a waterproofing testing device for penetrating crystalline concrete based on a humidity sensor is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a device for detecting the waterproofness of penetrating crystallized concrete based on a humidity sensor, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a device for detecting the waterproofness of permeable crystalline concrete based on a humidity sensor, comprising a cabinet, a circular plate fixedly connected to the inner wall of the cabinet, a rotating column rotatably connected to the inner wall of the cabinet, a rotating disk fixedly connected to the circumferential surface of the rotating column, a fixing block fixedly connected to the circumferential surface of the rotating disk, a pull rod rotatably connected to the circumferential surface of the fixing block, a slider slidably connected to the inner wall of the cabinet, a stop block fixedly connected to the right side of the slider, and an elastic telescopic rod fixedly connected to the circumferential surface of the circular plate, wherein the telescopic end of the elastic telescopic rod...

The sealing plate contacts the circular plate and is used to seal the opening of the circular plate. The rotating column is fixedly connected to the output end of the motor. The connecting column contacts the circular plate, and... The connecting column is used to drive the hinge block to move and rotate, so that the clamping plate contacts the penetrating crystalline concrete sample and clamps and fixes the penetrating crystalline concrete sample. This can stabilize the contact state between the humidity sensor and the penetrating crystalline concrete sample, eliminate test errors caused by the displacement of the penetrating crystalline concrete sample, improve the accuracy of the device for testing the waterproofness of penetrating crystalline concrete, and can rub and scrape the surface of the penetrating crystalline concrete sample to simulate the minor damage that may occur in penetrating crystalline concrete in actual engineering. It can also activate the activity of the penetrating crystalline material, thereby more realistically testing its waterproof performance and self-healing ability.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-8One embodiment of the present invention is as follows: a device for detecting the waterproofness of permeable crystalline concrete based on a humidity sensor, comprising a cabinet 1, a circular plate 2 fixedly connected to the inner wall of the cabinet 1, a rotating column 5 rotatably connected to the inner wall of the cabinet 1, a rotating disk 6 fixedly connected to the circumferential surface of the rotating column 5, a fixing block 7 fixedly connected to the circumferential surface of the rotating disk 6, a pull rod 8 rotatably connected to the circumferential surface of the fixing block 7, a slider 9 slidably connected to the inner wall of the cabinet 1, a stop block 10 fixedly connected to the right side of the slider 9, and an elastic telescopic rod 11 fixedly connected to the circumferential surface of the circular plate 2. A movable column 12 is fixedly connected to the telescopic end of 1. A clamping plate 13 is fixedly connected to the circumferential surface of the movable column 12. A connecting column 14 is fixedly connected to the top of the rotating disk 6. A sealing plate 15 is fixedly connected to the circumferential surface of the connecting column 14. A hinge block 16 is rotatably connected to the circumferential surface of the connecting column 14 via a torsion spring. A connecting plate 17 is fixedly connected to the circumferential surface of the hinge block 16. A friction block 18 is fixedly connected to the inner wall of the connecting plate 17. A motor is fixedly connected to the inner wall of the cabinet 1. A penetrating crystallized concrete sample is placed on the inner wall of the circular plate 2. A humidity sensor is fixedly connected inside the penetrating crystallized concrete sample. When the device is started, the operator first needs to place the penetrating crystallized concrete sample inside the placement circular plate 2. After the operator has placed the penetrating crystallized concrete sample, the motor will start, and the motor output will drive the rotating column 5 to rotate. The rotation of the rotating column 5 will drive the rotating disk 6 to rotate. During the rotation of the rotating disk 6, the fixed block 7 will rotate. The rotation of the fixed block 7 will drive the pull rod 8 to rotate. During the rotation of the pull rod 8, the pull rod 8 will change its angle. During the angle adjustment process, the pull rod 8 will pull the slider 9 to move. At this time, the slider 9 slides on the inner wall of the cabinet 1. The movement will cause the abutment 10 to move. After moving a certain distance, the abutment 10 will contact the moving column 12. After contact with the moving column 12, the abutment 10 will continue to move, squeezing and pushing the moving column 12 to move. The movement of the moving column 12 will cause the clamping plate 13 to move. After moving a certain distance, the clamping plate 13 will contact the penetrating crystallized concrete sample and clamp and fix the penetrating crystallized concrete sample. This can stabilize the contact state between the humidity sensor and the penetrating crystallized concrete sample, eliminate the test error caused by the displacement of the penetrating crystallized concrete sample, and improve the accuracy of the device for testing the waterproofness of penetrating crystallized concrete. The inner wall of the cabinet 1 is provided with a sealing mechanism 3 for sealing during testing. The inner wall of the circular plate 2 is provided with a unloading mechanism 4 for unloading support. A water tank is fixedly connected to the inner wall of the cabinet 1. A pull rod 8 is rotatably connected to the circumferential surface of the slider 9 and is used to drive the slider 9 to move. The moving column 12 is located on the circumferential trajectory of the abutment block 10 and is used to push the moving column 12 to move. The clamping plate 13 is in contact with the circular plate 2 and is used to clamp the penetrating crystallized concrete sample. The sealing plate 15 is in contact with the circular plate 2 and is used to seal the opening of the circular plate 2. The rotating column 5 is fixedly connected to the output end of the motor. The connecting column 14 is in contact with the circular plate 2 and is used to drive the hinge block 16 to move and rotate. When the device is started, the rotation of the rotating column 5 will drive the rotating disk 6 to rotate, the rotation of the rotating disk 6 will drive the connecting column 14 to rotate, the rotation of the connecting column 14 will drive the sealing plate 15 to rotate, and the rotation of the connecting column 14 will drive the hinge block 16 to rotate. During the rotation of the hinge block 16, the hinge block 16 will synchronously drive the connecting plate 17 to rotate, and the rotation of the connecting plate 17 will drive the friction block 18 to rotate. During the synchronous rotation of the connecting plate 17 and the friction block 18, the surface of the penetrating crystallized concrete sample can be rubbed and scraped, which can simulate the micro-damage that may occur in penetrating crystallized concrete in actual engineering, and can activate the activity of penetrating crystallized material, thereby more realistically testing its waterproof performance and self-healing ability.

[0016] Overall working principle: The movement of the moving column 12 will drive the clamping plate 13 to move. After moving a certain distance, the clamping plate 13 will contact the penetrating crystalline concrete sample and clamp and fix the penetrating crystalline concrete sample. This can stabilize the contact state between the humidity sensor and the penetrating crystalline concrete sample, eliminate test errors caused by the displacement of the penetrating crystalline concrete sample, and improve the accuracy of the device for testing the waterproofness of penetrating crystalline concrete. The rotation of the connecting plate 17 will drive the friction block 18 to rotate. During the synchronous rotation of the connecting plate 17 and the friction block 18, the surface of the penetrating crystalline concrete sample can be rubbed and scraped. This can simulate the minor damage that may occur to the penetrating crystalline concrete in actual engineering, activate the activity of the penetrating crystalline material, and thus more realistically test its waterproof performance and self-healing ability.

[0017] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the sealing mechanism 3 includes a vertical plate 301, a cylinder 302, a sealing sleeve 303, a connecting pipe 304, an elastic telescopic rod 305, and a sealing disc 306. The vertical plate 301 is fixedly connected to the inner wall of the cabinet 1, the cylinder 302 is fixedly connected to the inner wall of the cabinet 1, the sealing sleeve 303 is fixedly connected to the telescopic end of the cylinder 302, the connecting pipe 304 is fixedly connected to the top of the sealing sleeve 303, the elastic telescopic rod 305 is fixedly connected to the inner wall of the sealing sleeve 303, and the sealing disc 306 is fixedly connected to the telescopic end of the elastic telescopic rod 305. When the device is started, after the operator places the penetrating crystallized concrete sample, cylinder 302 will activate. The telescopic end of cylinder 302 will drive the sealing sleeve 303 to move downwards. During this movement, the sealing sleeve 303 will slide against the inner wall of the vertical plate 301. Simultaneously, the sealing sleeve 303 will move the connecting pipe 304. The movement of the sealing sleeve 303 will drive the elastic telescopic rod 305 to move, which in turn will drive the sealing disc 306 to move. After moving a certain distance, the sealing disc 306 will come into contact with the penetrating crystallized concrete sample placed inside the circular plate 2. At this point, the sealing disc 306 will continue to move downwards, and will be subjected to the reaction force of the penetrating crystallized concrete sample. The sealing disc 306 compresses the elastic telescopic rod 305, while the elastic telescopic rod 305 applies pressure to the sealing disc 306 through its own reset characteristics, so that the sealing disc 306 can tightly contact the top of the penetrating crystalline concrete sample until the sealing sleeve 303 contacts the placement circular plate 2. At this time, the cylinder 302 will stop moving, and water inside the water tank can be discharged into the interior of the placement circular plate 2 through the connecting pipe 304. The sealing disc 306 can isolate a part of the top of the penetrating crystalline concrete sample from the water, and the discharged water can only contact a part of the top area of ​​the penetrating crystalline concrete. This can control the path of water penetration, eliminate interference factors, forcibly limit the direction of water penetration, simulate real engineering scenarios, improve the accuracy of the device in testing the waterproofness of penetrating crystalline concrete, and ensure the stability of test data. The sealing mechanism 3 also includes a second fixing block 307, a second pull rod 308, and a sealing arc plate 309. The second fixing block 307 is fixedly connected to the top of the slider 9. The second pull rod 308 is rotatably connected to the circumferential surface of the second fixing block 307. The sealing arc plate 309 is slidably connected to the circumferential surface on which the circular plate 2 is placed. The sealing sleeve 303 is slidably connected to the inner wall of the vertical plate 301, and the vertical plate 301 is used to guide the sealing sleeve 303. One end of the sealing sleeve 303 is connected to the sealing plate 303, and the other end of the sealing sleeve 303 is connected to the water tank. The second pull rod 308 is rotatably connected to the circumferential surface of the sealing arc plate 309, and the second pull rod 308 is used to drive the sealing arc plate 309 to move. When the device is started, the slider 9 moves, which in turn moves the fixed block 307. The movement of the fixed block 307 in turn moves the pull rod 308. During the movement of the pull rod 308, it will contact the internal parts of the device and adjust its angle accordingly. During the angle adjustment, the pull rod 308 will push the sealing arc plate 309 upward. After moving upward a certain distance, the sealing arc plate 309 will contact the sealing sleeve 303. After contacting the sealing sleeve 303, the sealing arc plate 309 can seal the connection gap between the circular plate 2 and the sealing sleeve 303, preventing water from leaking out through the gap during the testing of penetrating crystalline concrete, thus avoiding reducing the efficiency of the device in testing the waterproofness of penetrating crystalline concrete. The unloading mechanism 4 includes an elastic telescopic rod 401, a protrusion 402, a horizontal plate 403, a cross plate 404, a fixed column 405, a hinged arc block 406, and a limiting block 407. The elastic telescopic rod 401 is fixedly connected to the inner wall of the circular plate 2. The protrusion 402 is fixedly connected to the telescopic end of the elastic telescopic rod 401. The horizontal plate 403 is fixedly connected to the inner wall of the protrusion 402. The cross plate 404 is slidably connected to the inner wall of the horizontal plate 403. The fixed column 405 is fixedly connected to the circumferential surface of the rotating column 5. The hinged arc block 406 is rotatably connected to the circumferential surface of the fixed column 405 through a torsion spring. The limiting block 407 is fixedly connected to the circumferential surface of the fixed column 405. When the device is started, the motor drives the rotating column 5 to rotate clockwise. During this rotation, the rotating column 5 drives the fixed column 405 to rotate, which in turn drives the hinged arc block 406 to rotate. Simultaneously, the fixed column 405 also drives the limiting block 407 to rotate. After the hinged arc block 406 rotates a certain angle, it contacts the protrusion 402. At this point, the protrusion 402 can apply a reaction force to press the hinged arc block 406 during its rotation. Under this pressure, the hinged arc block 406 rotates on the circumference of the fixed column 405, thus transmitting the force to the protrusion 402. Similarly, when the motor drives the rotating column 5 to rotate counterclockwise, the hinged arc block 406 rotates again. The arc block 406 will rotate, but after the articulated arc block 406 contacts the protrusion 402, the limiting block 407 will limit the rotation of the articulated arc block 406. The limiting block 407 will prevent the articulated arc block 406 from rotating after contacting the protrusion 402. After the articulated arc block 406 cannot rotate, it can squeeze and push the protrusion 402 during the movement. The movement of the protrusion 402 will drive the horizontal plate 403 to move. The movement of the horizontal plate 403 will drive the cross plate 404 to rise. The cross plate 404 can push the penetrating crystallized concrete sample placed inside the circular plate 2, which can improve the unloading speed of the device and indirectly improve the detection and testing efficiency of the device for penetrating crystallized concrete. The unloading mechanism 4 also includes a connecting rod 408 and a groove block 409. The connecting rod 408 is rotatably connected to the inner wall of the cross plate 404 via a torsion spring. The groove block 409 is slidably connected to the top of the horizontal plate 403. The protrusion 402 is located on the movement trajectory of the hinged arc block 406. The limiting block 407 is in contact with the hinged arc block 406 and is used to limit the rotation angle of the hinged arc block 406. The connecting rod 408 is rotatably connected to the circumferential surface of the groove block 409. When the device is started, the rise of the cross plate 404 will synchronously drive the connecting rod 408 to rise. The rise of the connecting rod 408 will drive the groove block 409 to rise synchronously. When the cross plate 404 comes into contact with the penetrating crystallizing concrete, the cross plate 404 will slide a certain distance on the inner wall of the horizontal plate 403. At this time, the cross plate 404 can drive the connecting rod 408 to move as it moves downward. During the movement, the connecting rod 408 can drive the groove block 409 to slide on the top of the horizontal plate 403. Similarly, the connecting rod 408 can be reset by its own torsion spring and drive the groove block 409 to reset. This can release the stress of the cross plate 404 pushing the penetrating crystallizing concrete, extend the service life of the internal parts of the device, and reduce the replacement cost of the device.

[0018] Overall working principle: The sealing disc 306 isolates a portion of the top of the penetrating crystalline concrete sample from water, allowing the discharged water to contact only a small area of ​​the top of the concrete. This controls the water penetration path, eliminates interference factors, and forcibly limits the direction of water penetration, simulating a real engineering scenario. This improves the accuracy of the device's test for the waterproofness of penetrating crystalline concrete and ensures stable test data. After contacting the sealing sleeve 303, the sealing arc plate 309 seals the connection gap between the circular plate 2 and the sealing sleeve 303, preventing water from passing through during the test of the penetrating crystalline concrete. To prevent leakage through gaps and reduce the efficiency of the device in testing the waterproofness of penetrating crystalline concrete, the movement of the protrusion 402 will cause the horizontal plate 403 to move, which in turn will cause the cross plate 404 to rise. The cross plate 404 can push the penetrating crystalline concrete sample placed inside the circular plate 2, which can improve the unloading speed of the device and indirectly improve the testing efficiency of the device for penetrating crystalline concrete. The connecting rod 408 can be reset by its own torsion spring and drive the groove block 409 to reset, which can release the stress of the cross plate 404 pushing the penetrating crystalline concrete, extend the service life of the internal parts of the device, and reduce the replacement cost of the device.
