Description

Technical Field

[0001] The invention belongs to the technical field of concrete detection, and in particular relates to a concrete structure permeability detection device. Background Art

[0002] As an indispensable material in modern construction, the stability and durability of concrete structure performance are crucial to building safety. Permeability is one of the key indicators for evaluating the quality of concrete structure. Permeability testing can reveal the pore structure, crack distribution and impermeability of concrete, thus providing an important basis for the maintenance and repair of concrete structures.

[0003] With the advancement of science and technology, the permeability detection technology of concrete structures has also experienced significant development. Traditional detection methods mainly rely on manual observation and simple physical tests, such as water injection method, gas permeation method, etc. Although these methods can reflect the permeability of concrete to a certain extent, they have disadvantages such as low detection efficiency, inaccurate results, and damage to concrete. Although the existing concrete structure permeability detection technology has made significant progress, the operation process of some detection devices is relatively complicated, requiring staff to fix the concrete structure during the detection process and provide a sealed environment, resulting in the device not only needing to fix the concrete structure through a mechanical structure, but also needing to seal the detection device, making the use of the device more inconvenient and the operation more cumbersome, so the staff needs to improve it.

The connecting frame 3 serves as a bridge connecting the sealing cover 2 and various transmission components, ensuring the stability and compactness of the entire structure. The protective box 4 effectively protects the servo motor 5 from interference and damage from the external environment.

[0046] The concrete structure sample to be tested is placed in the testing frame 1 .

[0047] The sealing cover 2 is closed, and the positioning plate 13 and other components inside the device are adjusted by connecting the first sleeve pipe 42 and the second sleeve pipe and other structures on the frame 3 to ensure that the sample in the detection frame is correctly fixed and sealed.

[0048] The servo motor 5 is started through the control panel 41. The servo motor drives the first transmission gear 8 and the first movable rod 9 to rotate through the driving rod 6 and the driving gear 7.

[0063] Working principle: The output end of the servo motor 5 drives the driving rod 6 to rotate. The front end of the driving rod 6 is fixedly connected with a driving gear 7. The rotation of the driving gear 7 simultaneously drives the first transmission gear 8 meshed on both sides of the surface and the second transmission gear 23 meshed on the top to rotate. The rotation of the second transmission gear 23 drives the third movable rod 24 to rotate. The top of the third movable rod 24 is fixedly connected with a third threaded rod 25. Since the third threaded rod 25 is threadedly connected with the second threaded sleeve 26, the second threaded sleeve 26 will move according to the rotation direction. The top of the second threaded sleeve 26 is fixedly connected with a mounting plate 27. The top of the mounting plate 27 is fixedly connected to the bottom of the sealing cover 2. Therefore, the movement of the second threaded sleeve 26 will drive the sealing cover 2 to move up and down, adjust the tightness between it and the detection frame 1, and ensure the sealing during the detection process.

[0064] The rotation of the driving gear 7 also drives the first transmission gear 8 to rotate. A first movable rod 9 is fixedly connected to one side of the first transmission gear 8. One end of the first movable rod 9 is fixedly connected to a first threaded rod 11. The surface of the first threaded rod 11 is threadedly connected to a first threaded sleeve 12. One end of the first threaded sleeve 12 is fixedly connected to a positioning plate 13. As the first transmission gear 8 rotates, the first threaded rod 11 will drive the first threaded sleeve 12 and the positioning plate 13 thereon to move, thereby fixing the concrete structure placed in the detection frame 1.

[0065] The surface of the first movable rod 9 is also fixedly connected to the first driving wheel 14, and the surface of the first driving wheel 14 is rotatably connected to the first transmission belt 15. The first transmission belt 15 then drives the second movable rod 17 and the second driving wheel 18 thereon to rotate. The second driving wheel 18 then drives the second transmission wheel 20 to rotate via the second transmission belt 19. Since the second transmission wheel 20 is threadedly connected to the second threaded rod 21, the second threaded rod 21 will drive the extrusion plate 22 to move according to the rotation direction, thereby further realizing the extrusion and fixation of the concrete structure.

[0066] A connecting hole 28 is provided on the back of the detection frame 1, and a water pipe 29 is inserted through the inner wall of the connecting hole 28. One end of the water pipe 29 is fixedly connected to a nozzle 30 for spraying detection water onto the surface of the concrete structure.

[0067] A pressure sensor 35 and a flow meter 36 are provided on the inner wall of the water pipe 29. The pressure sensor 35 can monitor the pressure changes of the spraying water flow in real time, thereby reflecting the penetration resistance of the surface of the concrete structure. The flow meter 36 can accurately measure the water flow through the water pipe 29. Combining the data of the pressure sensor 35 and the flow meter 36, the penetration rate and penetration amount of the concrete structure can be further analyzed, providing strong data support for evaluating the permeability performance of the concrete structure.

[0068] A partition 37 is fixedly connected to the inner wall of the detection frame 1, and a penetration net 38 is fixedly connected to the top of the partition 37 for collecting water that penetrates the concrete structure. A drain pipe 39 is fixedly connected to the bottom of one side of the detection frame 1, and a valve is rotatably connected to the inner wall of the drain pipe 39 for controlling the drainage process. An observation frame 52 is fixedly connected to the surface of the detection frame 1, and tempered glass is fixedly connected to the inner wall of the observation frame 52 for easy observation of the situation during the detection process.

[0069] The control panel 41 is used to control the start and stop of the servo motor and adjust its parameters such as the rotation speed, so as to achieve precise control of the entire detection process.
