Abstract
Description
Technical Field
[0001] This application relates to the field of concrete crack detection technology, and in particular to a concrete crack monitoring device for sewage treatment plant structures. Background Technology
[0002] In the wastewater treatment industry, cracks in concrete structures are a common safety hazard. These cracks can lead to problems such as leakage and corrosion, seriously threatening the normal operation and safety performance of wastewater treatment systems. Therefore, monitoring of concrete structures is necessary.
[0003] Currently, the primary method for early monitoring of cracks in concrete structures relies on ultrasonic testing equipment. While this equipment can accurately detect minute cracks that appear in the early stages of concrete formation, it is complex and requires professional personnel to operate. It presents significant challenges for non-professionals and thus has its limitations. Utility Model Content
[0004] To address the challenge of monitoring cracks in concrete structures, this application provides a device for monitoring concrete cracks in wastewater treatment plant structures.
[0005] The technical solution for the concrete crack monitoring device for sewage treatment plant structures provided in this application is as follows:
[0006] A concrete crack monitoring device for sewage treatment plant structures includes a main board and a secondary board, with a gap between them and both mounted on the concrete structure. A hollow display cylinder is detachably mounted on the main board, and a one-way valve and a transparent observation window are provided on the display cylinder. A hollow glass column is disposed inside the display cylinder, containing peroxide. A mixture of fluorescent and lipid compounds is also contained within the display cylinder. A positioning element for fixing the glass column is provided on the display cylinder. A pull rod slidably passes between the inner and outer walls of the display cylinder, with the glass column positioned at one end of the pull rod. The end of the pull rod facing away from the glass column extends to the secondary board, where a fixing element for securing the pull rod is provided.
[0007] By adopting the above technical solution, workers first fix the main board and secondary board to the concrete structure, then fix the glass column inside the display tube using positioning components, and then fix the display tube to the main board. One end of the tie rod is then fixed to the secondary board using fasteners. Since the glass cannot be stretched and the reaction between peroxide and lipid compounds causes fluorescence, when cracks occur in the concrete structure between the main board and secondary board, the tensile force generated by the cracks will pull the glass column through the tie rod, allowing the peroxide inside the glass column to react with the lipid compounds inside the display tube. Workers can then observe the fluorescence inside the display tube through the observation window, which facilitates the monitoring of small cracks in the concrete structure and reduces the difficulty of monitoring the concrete structure.
[0008] Optionally, the display tube includes an end plate, an end tube, and an end cylinder. The end cylinder is hollow inside and open at one end. The end tube is located between the end plate and the end cylinder. The end tube is coaxially and detachably mounted on the end cylinder. A first sealing ring is provided between the end tube and the end cylinder. The pull rod slides coaxially through the end cylinder. A second sealing ring is provided between the end cylinder and the pull rod.
[0009] By adopting the above technical solution, the difficulty for workers to install the glass column inside the display tube is reduced, and at the same time, it is convenient for workers to fill the display tube with a mixture of fluorescent and lipid compounds.
[0010] Optionally, there is an angle between the axis of the glass column and the axis of the end tube. The positioning element includes an inner tube disposed on the end plate. One end of the glass column is inserted into the inner tube. A bridge tube is slidably sleeved on the end of the glass column facing away from the inner tube. A connecting rod is hinged between the bridge tube and the pull rod inside the end tube.
[0011] By adopting the above technical solution, since the tie rod is coaxially slidably arranged on the end tube, and there is an angle between the axis of the glass column and the axis of the end tube, and one end of the glass column is inserted into the inner tube, when the concrete structure cracks and the tie rod is pulled, the movement distance of the tie rod is very small. However, with the help of the connecting rod, the tie rod can better break the glass column, thereby allowing the peroxide inside the glass column to diffuse into the display tube. This helps to improve the accuracy of monitoring cracks in concrete structures.
[0012] Optionally, the glass column is provided with a fracture groove in the circumferential direction.
[0013] By adopting the above technical solution, the movable lever can be used to break the glass column.
[0014] Optionally, a polygonal anti-pressure plate is provided on the tie rod outside the end cylinder. The anti-pressure plate is used to abut against the end of the end cylinder. An anti-rotation plate is provided on the end cylinder. The anti-pressure plate and the anti-rotation plate are inserted into each other. An anti-rotation groove is provided on the anti-rotation plate for the anti-pressure plate to be inserted.
[0015] By adopting the above technical solution, when workers install glass columns, the anti-pressure plate can limit the maximum sliding distance of the tie rod inside the end cylinder, thereby reducing the possibility of the glass column being crushed. At the same time, the anti-pressure plate can limit the rotation of the tie rod, thereby reducing the damage to the glass column caused by the rotation of the connecting rod. Thus, the possibility of workers damaging the glass column during installation is reduced.
[0016] Optionally, the fixing component includes an adjusting plate, an adjusting bolt passing through the adjusting plate, a slotted hole for the adjusting bolt to pass through on the secondary plate, an adjusting nut threaded onto the adjusting bolt on the side of the secondary plate opposite to the adjusting plate, a vertical plate provided on the adjusting plate, a pressure block detachably provided on the vertical plate, and a rod groove for accommodating the pull rod together with the vertical plate and the pressure block.
[0017] By adopting the above technical solution, the surface of the poured concrete may be uneven. Workers can adjust the position of the adjustment plate to keep the end of the tie rod facing away from the display cylinder straight, which helps to improve the accuracy of monitoring cracks in concrete structures.
[0018] Optionally, the tie rod includes multiple unit rods, and adjacent unit rods are detachably connected.
[0019] By adopting the above technical solution, on the one hand, it is convenient for workers to move and assemble the tie rods, and on the other hand, workers can adapt to concrete structures of different widths through assembly.
[0020] Optionally, the motherboard is detachably provided with multiple fixing rings, the display tube is mounted inside the fixing rings, and the fixing rings are threaded with fastening bolts, which are used to press the display tube against the inner side wall of the fixing rings.
[0021] By adopting the above technical solution, the fixing ring simplifies the process of workers fixing the display tube to the motherboard.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. The worker first fixes the main board and secondary board to the concrete structure, then fixes the glass column inside the display tube using positioning components. After that, the display tube is fixed to the main board, and one end of the tie rod is fixed to the secondary board using fasteners. Since the glass cannot be stretched, and the reaction between the peroxide and lipid compounds will cause fluorescence, when a crack occurs in the concrete structure between the main board and secondary board, the tensile force generated by the crack will pull the glass column through the tie rod, thereby allowing the peroxide inside the glass column to react with the lipid compounds inside the display tube. The worker can observe the fluorescence inside the display tube through the observation window, thus facilitating the worker's monitoring of small cracks in the concrete structure.
[0024] 2. Since the tie rod is coaxially slidably arranged on the end tube, and there is an angle between the axis of the glass column and the axis of the end tube, and one end of the glass column is inserted into the inner tube, when the concrete structure cracks and the tie rod is pulled, the movement distance of the tie rod is very small. However, with the help of the connecting rod, the tie rod can better break the glass column, thereby allowing the peroxide inside the glass column to diffuse into the display tube. This helps to improve the accuracy of monitoring cracks in concrete structures.
[0025] 3. When workers install the glass column, the anti-pressure plate can limit the maximum sliding distance of the tie rod inside the end tube, thereby reducing the possibility of the glass column being crushed. At the same time, the anti-pressure plate can limit the rotation of the tie rod, thereby reducing the damage to the glass column caused by the rotation of the connecting rod. Thus, the possibility of workers damaging the glass column during installation is reduced. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.
[0030] This application discloses a device for monitoring concrete cracks in sewage treatment plant structures.
[0031] Reference Figure 1 A concrete crack monitoring device for a sewage treatment plant structure includes a main plate 2 and a secondary plate 3. There is a gap between the main plate 2 and the secondary plate 3, and both are bolted to the concrete structure 1. Two fixing rings 15 are bolted to the main plate 2. A hollow display tube 4 is mounted inside the two fixing rings 15. Fastening bolts 16 are threaded onto the fixing rings 15. The fastening bolts 16 are used to press the display tube 4 against the inner side wall of the fixing rings 15.
[0032] Reference Figure 1 and Figure 2 The display cylinder 4 is welded with a one-way valve 5 that communicates with the interior of the display cylinder 4. A transparent observation window 6 is arranged on the display cylinder 4. A hollow glass column 7 is arranged inside the display cylinder 4. The glass column 7 is filled with peroxide. The display cylinder 4 is filled with a mixture of fluorescent and lipid compounds.
[0033] Reference Figure 1 and Figure 2 The display cylinder 4 is provided with a positioning element 8 for fixing the glass column 7. A pull rod 9 is slidably passed between the inner and outer walls of the display cylinder 4. The pull rod 9 includes multiple unit rods 91, and two adjacent unit rods 91 are threadedly connected. The glass column 7 is arranged at one end of the pull rod 9. The end of the pull rod 9 facing away from the glass column 7 extends to the secondary plate 3. A fixing element 10 for fixing the pull rod 9 is arranged on the secondary plate 3.
[0034] Reference Figure 1 and Figure 2 The display cylinder 4 includes an end plate 41, an end tube 42, and an end cylinder 43. A one-way valve 5 is welded to the end plate 41. The end cylinder 43 is hollow inside and open at one end. The end tube 42 is located between the end plate 41 and the end cylinder 43. The end tube 42 is coaxially bolted to the open end of the end cylinder 43. The end plate 41 is welded to the end of the end tube 42 facing away from the end cylinder 43. A first sealing ring 44 is arranged between the end tube 42 and the end cylinder 43. The pull rod 9 slides coaxially through the end cylinder 43. A second sealing ring 45 is arranged between the end cylinder 43 and the pull rod 9.
[0035] Reference Figure 2 A polygonal anti-pressure plate 12 is welded to the tie rod 9 outside the end cylinder 43. The anti-pressure plate 12 is used to abut against the end of the end cylinder 43. An anti-rotation plate 13 is welded to the end cylinder 43. The anti-pressure plate 12 and the anti-rotation plate 13 are inserted into each other. An anti-rotation groove 14 is provided on the anti-rotation plate 13 for the anti-pressure plate 12 to be inserted into.
[0036] Reference Figure 2There is an angle between the axis of the glass column 7 and the axis of the end tube 42. The glass column 7 has a fracture groove 11 in the circumferential direction. The positioning component 8 includes an inner tube 81 welded to the end plate 41. One end of the glass column 7 is inserted into the inner tube 81. A bridge tube 82 is slidably sleeved on the end of the glass column 7 facing away from the inner tube 81. A connecting rod 83 is hinged between the bridge tube 82 and the tie rod 9 in the end tube 43.
[0037] The workers first fix the main plate 2 and the secondary plate 3 on the concrete structure 1 to be monitored. Then, they insert the glass column 7 containing peroxide into the inner tube 81. Next, they insert the anti-pressure plate 12 into the anti-rotation groove 14 of the anti-rotation plate 13 and keep it stationary. Then, they put the bridge tube 82 on the connecting rod 83 onto the glass column 7. Finally, they bolt the end tube 43 to the end tube 42 to complete the fixation of the glass column 7.
[0038] The worker places the assembled display tube 4 on the fixing ring 15, then tightens the fastening bolts 16 to fix the display tube 4 on the fixing ring 15. Then, a mixture of fluorescent and lipid compounds is injected into the display tube 4 through the one-way valve 5. The air inside the display tube 4 is discharged at the same time during the injection of the mixture through the one-way valve 5.
[0039] Reference Figure 1 and Figure 2 The fixing component 10 includes an adjusting plate 101, an adjusting bolt 102 passing through the adjusting plate 101, a waist-shaped hole 103 for the adjusting bolt 102 to pass through and slide on the secondary plate 3, an adjusting nut 104 threaded onto the adjusting bolt 102 on the side of the secondary plate 3 facing away from the adjusting plate 101, a vertical plate 105 welded onto the adjusting plate 101, a pressure block 106 bolted onto the vertical plate 105, and a rod groove 107 for accommodating the pull rod 9 together with the vertical plate 105 and the pressure block 106.
[0040] Workers splice multiple unit rods 91 to form a tie rod 9 according to the distance between the main board 2 and the secondary board 3. Then, according to the positional relationship between the upright plate 105 and the tie rod 9, they adjust the position of the adjusting plate 101 and tighten the adjusting nut 104. Finally, the tie rod 9 is fixed to the upright plate 105 by the pressure block 106.
[0041] When a crack occurs in the concrete structure 1 between the main plate 2 and the secondary plate 3, the tensile force generated by the crack is transmitted to the tie rod 9 through the secondary plate 3. Since the glass column 7 is tilted and cannot be stretched, the moving tie rod 9 drives the bridge tube 82 to move through the connecting rod 83. However, since the glass column 7 is restricted by the inner tube 81, it cannot move along the axis of the tie rod 9.
[0042] Therefore, the glass column 7 will be broken at the weak point of the fracture groove 11, which will cause the peroxide in the glass column 7 to diffuse into the display tube 4 and react with the lipid compounds, thereby causing fluorescence. Workers can easily understand that cracks have occurred in the concrete structure 1 between the main board 2 and the secondary board 3 through the observation window 6.
[0043] The implementation principle of the concrete crack monitoring device for sewage treatment plant structures in this application embodiment is as follows: First, the worker fixes the main plate 2 and the secondary plate 3 on the concrete structure 1 to be monitored. Then, the glass column 7 containing peroxide is inserted into the inner tube 81. Next, the anti-pressure plate 12 is inserted into the anti-rotation groove 14 of the anti-rotation plate 13 and kept still. Then, the bridge tube 82 on the connecting rod 83 is sleeved on the glass column 7. Finally, the end tube 43 is bolted to the end tube 42, thereby completing the fixation of the glass column 7.
[0044] The worker places the assembled display tube 4 on the fixing ring 15, then tightens the fastening bolts 16 to fix the display tube 4 on the fixing ring 15. Then, a mixture of fluorescent and lipid compounds is injected into the display tube 4 through the one-way valve 5. The air inside the display tube 4 is discharged at the same time during the injection of the mixture through the one-way valve 5.
[0045] Workers splice multiple unit rods 91 to form a tie rod 9 according to the distance between the main board 2 and the secondary board 3. Then, according to the positional relationship between the upright plate 105 and the tie rod 9, they adjust the position of the adjusting plate 101 and tighten the adjusting nut 104. Finally, the tie rod 9 is fixed to the upright plate 105 by the pressure block 106.
[0046] When a crack occurs in the concrete structure 1 between the main plate 2 and the secondary plate 3, the tensile force generated by the crack is transmitted to the tie rod 9 through the secondary plate 3. Since the glass column 7 is tilted and cannot be stretched, the moving tie rod 9 drives the bridge tube 82 to move through the connecting rod 83. However, since the glass column 7 is restricted by the inner tube 81, it cannot move along the axis of the tie rod 9.
[0047] Therefore, the glass column 7 will be broken at the weak point of the fracture groove 11, which will cause the peroxide in the glass column 7 to diffuse into the display tube 4 and react with the lipid compounds, thereby causing fluorescence. Workers can easily understand that cracks have occurred in the concrete structure 1 between the main board 2 and the secondary board 3 through the observation window 6.
[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
