Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of grouting material performance detection, in particular to anti-aging detection equipment and a detection method for grouting material for water conservancy construction. Background Art
[0002] The core role of UV anti-aging testing of water conservancy concrete grouting materials is to evaluate their durability under long-term sunlight exposure, predict their service life in actual projects, and reveal the physical and chemical degradation mechanisms caused by ultraviolet rays (such as surface powdering, discoloration, cracking, strength loss and increased permeability). It provides a key basis for the research and development of material formulas with better anti-aging performance (especially the selection of polymer additives and anti-UV additives), and ultimately ensures the long-term safety and reliability of water conservancy projects (such as dams and tunnel linings); the detection is mainly achieved through artificial accelerated ultraviolet aging tests. The core equipment is the ultraviolet aging test chamber (QUV), which uses specific lamps (such as UVA-340) to simulate the most destructive short-wave ultraviolet rays in sunlight. The testing process first requires the preparation and curing of standard test specimens, testing their initial appearance, surface hardness, mechanical strength (compression / flexural strength), bonding strength, and permeability as a benchmark. The specimens are then placed in an aging chamber and periodically exposed to the specified UV irradiance, temperature, and possible condensation cycles. During and after the aging process, the specimens are systematically monitored and evaluated for changes in appearance (color, chalking, cracking, etc.), surface hardness degradation, mechanical strength loss, bonding performance degradation, and permeability degradation. By comparing the initial performance with that of untreated specimens, a comprehensive assessment of the material's UV resistance and expected durability is made.
[0003] For example, the UV detector for anti-aging of grouting materials for water conservancy construction disclosed in the authorization announcement number CN118858133B includes a chassis, a cooling mechanism, and a rotating mechanism. A partition is fixedly installed between the inner walls of the two sides of the chassis, and the partition divides the internal space of the chassis into a test area and a blank area. The rotating mechanism is arranged on the chassis. A rotating rod is rotatably installed on the inner wall of one side of the test area, and a fixed rod is fixedly installed on the inner wall of the other side of the chassis. The rotating mechanism controls the start of the first motor to drive the rotating rod to rotate, thereby rotating each suspension arm, and then driving the placement plate suspended on each rotating block and the test consolidation parts thereon to continuously rotate periodically relative to the UV aging test lamp. However, when the above technical solution uses the UV aging test lamp to irradiate the periodically rotating test consolidation parts, all the test consolidation parts are subjected to aging irradiation treatment of equal radiation intensity in the detection room during the same period of time. At this time, it is difficult to meet the requirements of synchronous aging detection of test consolidation parts with ultraviolet radiation intensity as a variable, that is, only aging data at a single intensity level can be generated. If the influence of different strengths (such as high, medium and low) is to be investigated, independent tests must be conducted in batches: in the first test, a certain strength is set to treat all the specimens. After completion, the specimens are replaced or the strength setting is adjusted for the second test, and so on. This is too time-consuming. Moreover, when testing in batches, even if efforts are made to keep the temperature and humidity conditions consistent, slight fluctuations between batches are still inevitable, which affects the detection accuracy of hydraulic concrete grouting materials. Summary of the Invention

[0017] The present invention also provides a method for detecting anti-aging of grouting materials for water conservancy construction, such as the above-mentioned anti-aging detection device for grouting materials for water conservancy construction, comprising the following steps:
[0018] S101: Four standard grouting material prismatic consolidation pieces that have been cured in the same batch are securely placed on the four-plate synchronous intermittent rotating assembly in the target test chamber, ensuring that the specimens are firmly fixed and the light-receiving surface faces the center of the second fluorescent UV lamp. The same operation is then repeated in the remaining three test chambers, so that each test chamber carries four homologous consolidation pieces.
[0019] S102: Activate the fluorescent UV lamp 1 on the top of each chamber and the fluorescent UV lamp 2 at the center of the support platform for preheating. Simultaneously, independently set the target UV radiation intensity for each test chamber, including low, medium, and high levels. The drive parameters of the sprocket drive assembly and the electrothermal air intake assembly are uniformly configured to adjust the rotation cycle and frequency of the four-disc synchronous intermittent rotation assembly, as well as the temperature setting value inside the electrothermal air intake assembly and the total test duration.
[0020] S103: After confirming that the equipment parameters are correct, the sprocket drive assembly drives the four-disc synchronous intermittent rotation assembly in all test chambers to perform intermittent synchronous rotation according to a preset rhythm. The electric heating air inlet assembly delivers stable hot air to the corresponding test chamber to maintain uniform temperature in the box;
[0021] S104: During the test operation, a preset downtime period is set, and the staff temporarily turns off the fluorescent UV lamp 1 and the fluorescent UV lamp 2, and enters the inspection room to perform non-destructive status recording of the consolidated parts;
[0022] S105: After the preset aging time is reached, the UV lamp in the equipment is turned off and the rotation of the four-disc synchronous intermittent rotating assembly is stopped. The staff takes out the consolidated parts in each testing room in turn, groups them according to the radiation intensity level, and conducts performance testing.
[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the anti-aging detection equipment for grouting materials for water conservancy construction and the detection method thereof are provided with a structure that cooperates with each other, such as an organic shell, a skeleton, four detection chambers, a fluorescent ultraviolet lamp 1, a fluorescent ultraviolet lamp 2, an electric heating air inlet assembly, a parallel heat exhaust assembly, a four-disc synchronous intermittent rotating assembly and a sprocket drive assembly. Four standard grouting material prismatic consolidation pieces to be subjected to anti-ultraviolet aging detection are placed on the four-disc synchronous intermittent rotating assembly in the detection chamber. During the detection, the fluorescent ultraviolet lamp 1 at the top and the fluorescent ultraviolet lamp 2 at the center position of the four-disc synchronous intermittent rotating assembly are irradiated with equal radiation intensity. Four standard consolidation pieces are placed in the remaining detection chambers according to the same steps, and the ultraviolet radiation intensity in each detection chamber is controlled to be inconsistent. The sprocket drive assembly drives the consolidation pieces on each four-disc synchronous intermittent rotating assembly to rotate, and the electric heating air inlet assembly supplies heat to the detection chamber, so as to achieve aging irradiation treatment of different ultraviolet radiation intensities for the same batch of standard consolidation pieces under the same environmental conditions within the same period of time.
[0024] Through the independent intensity control design of multiple test chambers, four standard consolidated components prepared from the same batch were simultaneously exposed to environments with different UV radiation intensities under exactly the same initial performance and starting time. Each test chamber shared a unified parallel heat removal assembly, sprocket drive assembly, and independently controlled electric heating air inlet assembly, ensuring that all specimens experienced strictly consistent temperature and humidity conditions, rotation cycles, and time history during the aging process. The only differentiating variable was the UV radiation intensity in the test chamber. This avoided interference such as temperature and humidity drift and lamp tube attenuation caused by batch time differences in traditional serial testing. The aging process under different radiation intensities was strictly time synchronized and environmental baseline consistency was achieved, providing a high-precision experimental basis for revealing pure radiation intensity effects. After synchronized aging, performance differences between different intensity groups (such as strength loss rate and degree of surface degradation) can be fully attributed to the effect of radiation intensity, completely eliminating data contamination caused by the discreteness of the specimens themselves. This makes aging data at different radiation intensity levels directly comparable, significantly improving the accuracy of experimental conclusions.
[0025] Secondly, through the parallel architecture of multiple test rooms, the same batch of consolidated parts can be simultaneously exposed to four preset radiation intensity environments within the same time period. A single test can obtain aging data under all target intensities at one time, shortening the total test cycle to more than half of the traditional method. For example, to evaluate low, medium and high intensities, three rounds of independent tests are required traditionally, but this solution can be completed in one round, which triples the efficiency. All test rooms start, run and end synchronously, and the test process is seamlessly connected. The sprocket drive assembly, four-disc synchronous intermittent rotation assembly, electric heating air intake assembly and parallel heat exhaust assembly continuously provide a uniform environment for all test rooms, avoiding downtime and waiting caused by batch switching, reducing the time and manpower required for traditional batch testing, and accelerating the process of collecting UV anti-aging data of grouting materials for water conservancy construction.

[0042] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0043] Embodiment 1, by Figures 1 to 7 The present invention includes a casing 1, a frame 2 is fixed to the bottom of the casing 1, and an outer door 101 is installed on one side of the outer wall of the casing 1 by a hinge. Four independent and isolated detection chambers 3 are installed inside the frame 2, and an inner door 301 is installed on one side of the opening outer wall of the detection chamber 3 by a hinge, and an electric heating air inlet assembly 4 is installed on the top of the detection chamber 3. The detection chamber 3 and the casing 1 are in a closed state by the inner door 301 and the outer door 101, ensuring that the standard grouting material prismatic consolidation member is in a relatively sealed environment in the detection chamber 3 and avoiding the influence of ultraviolet radiation between adjacent detection chambers 3;
[0044] Fluorescent ultraviolet lamps 12 are installed on both sides of the top of the detection chamber 3, and a parallel heat exhaust assembly 5 for exhausting the air inside the four detection chambers 3 is provided on the back of the housing 1;
[0045] A vertical shaft 7 is mounted between two detection chambers 3 in the same vertical direction for vertical rotation. A support platform 8 is fixed to the bottom of the detection chamber 3 on one side of the vertical shaft 7. A fluorescent ultraviolet lamp 9 is mounted at the center of the top of the support platform 8.
[0046] Fluorescent UV lamp 29 and fluorescent UV lamp 12 are used to accelerate the UV aging process of the consolidated parts. The central placement of fluorescent UV lamp 29 and the top placement of fluorescent UV lamp 12 can achieve multi-angle and multi-intensity irradiation, ensuring the aging effect of the sample under different lighting conditions, so as to fully simulate the ultraviolet changes in the natural environment and enhance the representativeness and reliability of the test;
[0047] The support platform 8 is internally installed with a four-disc synchronous intermittent rotating assembly 10 that is power-connected to the vertical shaft 7. The four-disc synchronous intermittent rotating assembly 10 is used to support the four grouting material consolidation parts and enable the four grouting material consolidation parts to rotate synchronously and intermittently. The bottom end of the casing 1 is installed with a sprocket drive assembly 6 for driving the two vertical shafts 7 to rotate.
[0048] Touch panel 11, touch panel 11 is mounted on the sloped wall at the top of housing 1, and the output end of touch panel 11 is electrically connected to the input ends of electric heating air inlet assembly 4, parallel heat exhaust assembly 5, sprocket drive assembly 6, fluorescent ultraviolet lamp 2 9, and fluorescent ultraviolet lamp 1 12;
[0049] Test chamber 3 is an independent radiation environment unit. Each test chamber can independently set and maintain different ultraviolet radiation intensities, that is, set the ultraviolet intensity output by fluorescent ultraviolet lamp 2 9 and fluorescent ultraviolet lamp 1 12. At the same time, they share unified temperature, humidity and rotation control, so that the same batch of test pieces can be simultaneously exposed to multiple radiation intensities in a single test, reducing the time difference and environmental drift problems of traditional serial testing.
[0050] The sprocket drive assembly 6 includes a reduction motor 601 installed on one side of the bottom end of the casing 1, a sprocket primary reduction transmission structure 602 installed between the driving shaft of the reduction motor 601 and the lower end of one of the vertical shafts 7, and a sprocket secondary constant speed transmission structure 603 installed between the lower ends of the two vertical shafts 7. The top end of the driving shaft of the reduction motor 601 is fixedly connected to the lower end of one of the vertical shafts 7 through a coupling. The input end of the reduction motor 601 is electrically connected to the output end of the touch panel 11. The sprocket drive assembly 6 is used to drive the two vertical shafts 7 to rotate synchronously. After the reduction motor 601 receives the control command from the touch panel 11, the reduction motor The machine 601 works according to the set direction, speed, angle and response time. At this time, the driving shaft of the reduction motor 601 drives one of the vertical shafts 7 to rotate through the sprocket primary reduction transmission structure 602, while the other vertical shaft 7 rotates synchronously driven by the sprocket secondary constant speed transmission structure 603. Then the vertical shaft 7 drives the two four-disc synchronous intermittent rotating assemblies 10 in the Z-axis direction to work synchronously. Through the rigid chain transmission, the four-disc synchronous intermittent rotating assemblies 10 in all the detection chambers 3 are forced to rotate at the same angle and the same period, ensuring that all test pieces complete the posture switching at the same time and maintain the consistency of environmental parameter monitoring.
[0051] A method for detecting anti-aging of grouting materials for water conservancy construction according to this embodiment, such as the above-mentioned anti-aging detection device for grouting materials for water conservancy construction, comprises the following steps:
[0052] S101: Four standard grouting material prismatic consolidation pieces that have been cured in the same batch are securely placed on the four-plate synchronous intermittent rotating assembly 10 in the target testing chamber 3, ensuring that the test pieces are firmly fixed and the light-receiving surface faces the center of the fluorescent ultraviolet lamp 9. The same operation is then repeated in the remaining three testing chambers 3, so that each testing chamber 3 carries four homologous consolidation pieces;
[0053] S102: Activate the fluorescent UV lamp 12 on the top of each chamber and the fluorescent UV lamp 2 9 at the center of the support platform 8 for preheating. At the same time, independently set the target UV radiation intensity for each detection chamber 3, including low, medium, and high levels. And uniformly configure the drive parameters of the sprocket drive assembly 6 and the electric heating air intake assembly 4 to adjust the rotation period and frequency of the four-disc synchronous intermittent rotation assembly 10, as well as the temperature setting value inside the electric heating air intake assembly 4 and the total test duration.
[0054] S103: After confirming that the equipment parameters are correct, the sprocket drive assembly 6 drives the four-disc synchronous intermittent rotation assembly 10 in all the detection chambers 3 to perform intermittent synchronous rotation according to a preset rhythm, and the electric heating air inlet assembly 4 delivers stable hot air to the corresponding detection chamber 3 to maintain a uniform temperature in the box;
[0055] S104: During the test operation, a preset downtime period is set, and the staff temporarily turns off the fluorescent UV lamp 12 and the fluorescent UV lamp 2 9, and enters the inspection room 3 to perform non-destructive status recording on the consolidated parts;
[0056] S105: After the preset aging time is reached, the UV lamp in the equipment is turned off and the four-disc synchronous intermittent rotation assembly 10 is stopped from rotating. The staff takes out the consolidated parts in each testing room 3 in turn, groups them according to the radiation intensity level, and conducts performance testing.
[0057] Example 2, based on Example 1, Figure 8 and Figure 9 It is given that the electric heating air inlet assembly 4 includes an air inlet pipe 401 installed at the air inlet position on one side of the top of the detection chamber 3, a U-shaped air duct 402 installed at one end of the air inlet pipe 401, and an air inlet fan 403 installed at one end of the U-shaped air duct 402 away from the air inlet pipe 401. An electric heating wire 404 is installed on one side inside the U-shaped air duct 402. The input ends of the electric heating wire 404 and the air inlet fan 403 are electrically connected to the output end of the touch panel 11. A temperature sensor 405 is installed on one side inside the U-shaped air duct 402. The output end of the temperature sensor 405 is electrically connected to the input end of the touch panel 11.
[0058] When the temperature in the test chamber 3 is controlled by the electric heating air inlet assembly 4, the staff controls the air inlet fan 403 and the electric heating wire 404 through the touch panel 11. The air inlet fan 403 sends external air into the U-shaped air duct 402. The air is heated by the electric heating wire 404 and then enters the test chamber 3 through the U-shaped air duct 402 and the air inlet duct 401. During this process, the temperature sensor 405 continuously monitors the air temperature in the U-shaped air duct 402, thereby adjusting the temperature of the test environment in the test chamber 3 to ensure that the ultraviolet aging process is carried out within the set temperature range. By ensuring that the temperature of each chamber is strictly consistent, the interference of thermal environment differences on the aging results is eliminated.
[0059] Example 3, based on Example 2, Figure 10 、 Figure 11 and Figure 12The support platform 8 includes a top plate 801 arranged on one side of the bottom of the detection chamber 3, four annular arc-shaped protrusions 802 with equal spacing formed in one piece at the bottom edge of the top plate 801, and a connecting platform 803 formed in one piece between the outer walls of two adjacent arc-shaped protrusions 802, one of the arc-shaped protrusions 802 is provided with a hollow groove 804, and a sprocket transmission structure 1005 for power connection between the four-disc synchronous intermittent rotation assembly 10 and the vertical shaft 7 is installed in the hollow groove 804. The hollow groove 804 provides sufficient space for the operation of the sprocket transmission structure 1005.
[0060] An upwardly extending hollow boss 901 is fixed at the center of the top of the top plate 801, and a second fluorescent UV lamp 9 is mounted on the top of the hollow boss 901. Since the second fluorescent UV lamp 9 is mounted at the center of the top of the top plate 801 via the hollow boss 901, the intermittent rotation of the tray 1008 allows each side of the specimen to be evenly illuminated, avoiding performance deviations caused by inconsistent irradiation angles, thereby obtaining a more realistic aging effect. In addition, the rotation speed and intermittent time of the sprocket drive assembly 6 and the four-disc synchronous intermittent rotation assembly 10 can be adjusted to meet different test requirements, providing a more flexible test plan.
[0061] The four-disc synchronous intermittent rotation assembly 10 includes a driving shaft 1002 fixed at the center position inside the top plate 801, an axis carrier plate 1001 fixed on the outer wall of one side of the arc-shaped protruding foot 802, a driven shaft 1003 rotatably installed on one side of the axis carrier plate 1001, and a groove wheel intermittent rotation structure 1004 installed on the upper end of the driven shaft 1003 for driving the driving shaft 1002 to rotate intermittently. The driven shaft 1003 and the vertical shaft 7 are connected by a sprocket transmission structure 1005. The top of the connecting platform 803 is rotatably installed with a The top end of the driven gear shaft 1007 passes through the outside of the top plate 801 and is fixed with a tray 1008. One end of the surface of the driving shaft 1002 is fixed with a central toothed disc 1006 that meshes with the four driven gear shafts 1007. The sheave intermittent rotation structure 1004 includes a driving dial fixed to one end of the surface of the driven shaft 1003, a driven sheave fixed to one end of the surface of the driving shaft 1002, and a round pin fixed to one side of the top end of the driving dial. The outer wall of the driven sheave is provided with six annular radial grooves with equal spacing;
[0062] When the vertical shaft 7 drives the four-disc synchronous intermittent rotation assembly 10 in the detection chamber 3 to work, the vertical shaft 7 transmits rotational power to the driven shaft 1003 through the sprocket transmission structure 1005, and then the driven shaft 1003 drives the driving shaft 1002 in the shaft carrier 1001 to rotate intermittently through the groove wheel intermittent rotation structure 1004. When the driving shaft 1002 is driven to rotate by the groove wheel intermittent rotation structure 1004, the driving shaft 1002 drives the four driven gear shafts 1007 on its outside to rotate synchronously through the center gear plate 1006, so that the prismatic consolidation part placed on the top of the tray 1008 can rotate intermittently. By realizing the synchronous and slow rotation of multiple consolidation parts, the multi-angle and multi-time changes of ultraviolet radiation in the natural environment are simulated.
[0063] Example 4, based on Example 2, Figure 13 、 Figure 14 and Figure 15 The parallel heat exhaust assembly 5 includes an exhaust box 501 installed on the back of the housing 1, a vertically connected standpipe 502 at one end of the exhaust box 501 away from the housing 1, and a solenoid valve 504 installed on the back side of the detection chamber 3 through an air duct. The end of the solenoid valve 504 away from the detection chamber 3 is also extended to the interior of the exhaust box 501 through another air duct. A centrifugal fan 503 is installed at the upper end of the standpipe 502, and the input end of the centrifugal fan 503 is electrically connected to the output end of the touch panel 11.
[0064] When the electric heating air inlet assembly 4 provides heat to maintain the internal temperature of the test room 3, in order to avoid excessive temperature affecting the test effect, the parallel heat exhaust assembly 5 independently regulates the exhaust gas emission of each room to prevent local overheating accumulation; the staff turns on a certain solenoid valve 504 through the touch panel 11, and then the centrifugal fan 503 generates negative pressure, so that the hot air in the corresponding test room 3 is discharged through the solenoid valve 504, the exhaust box 501, the riser 502 and the centrifugal fan 503, so as to quickly and evenly discharge the excess heat and maintain the stability of the test environment.
[0065] When used in the embodiments of the present application, the consolidation specimens used need to be cured under standard curing conditions (constant temperature and humidity) to a specified age, usually 28 days, to ensure that the benchmark performance is achieved. The surface of the specimens should be clean and flat, representative of the actual exposed surface, and simulate the construction surface conditions as needed, such as plastering treatment;
[0066] The staff placed four standard grouting material prismatic consolidation pieces that had been cured in the same batch firmly on the four-disc synchronous intermittent rotating assembly 10 of the target test room 3, ensuring that the test pieces were firmly fixed and the light-receiving surface was facing the center of the light source. The same operation was then repeated in the remaining three test rooms 3, so that each test room 3 was loaded with four homologous consolidation pieces. After closing the inner box door 301 of all test rooms 3 and the outer box door 101 of the casing 1, the equipment was started through the touch panel 11: the fluorescent ultraviolet lamp 12 on the top of each room and the fluorescent ultraviolet lamp 2 9 at the center of the support platform 8 were activated for preheating, and at the same time, the fluorescent ultraviolet lamp 12 on the top of each room and the fluorescent ultraviolet lamp 9 at the center of the support platform 8 were activated for preheating. Each test room 3 independently sets the target ultraviolet radiation intensity, including low, medium and high levels, and uniformly configures the drive parameters of the sprocket drive assembly 6 and the electric heating air inlet assembly 4 to adjust the rotation cycle and frequency of the four-disc synchronous intermittent rotation assembly 10 and the temperature setting value inside the electric heating air inlet assembly 4, and the total test time; after confirming that the equipment parameters are correct, the staff starts the sprocket drive assembly 6 through the touch panel 11, and the sprocket drive assembly 6 drives the four-disc synchronous intermittent rotation assembly 10 in all test rooms 3 to perform intermittent synchronous rotation according to the preset rhythm to ensure that the surfaces of the prismatic consolidation parts are uniform. Upon receiving light, the electric heating air inlet assembly 4 is turned on synchronously, and the electric heating air inlet assembly 4 delivers stable hot air to the corresponding detection chamber 3 to maintain the uniform temperature in the box, while the parallel heat exhaust assembly 5 works in real time to dynamically discharge exhaust gas and balance the air pressure, so that the temperature, humidity and rotation conditions in the detection chamber 3 are strictly consistent; during the test operation, at the preset regular shutdown window, such as every 24 hours, the staff briefly turns off the fluorescent ultraviolet lamp 12 and the fluorescent ultraviolet lamp 2 9, enters the detection chamber 3 to perform non-destructive status recording of the consolidated parts, including visual observation of surface discoloration, powdering or cracking signs, and uses A portable hardness tester detects changes in surface hardness, takes photos and archives them for comparison with the aging process; after reaching the preset aging time, the UV lamp in the equipment is turned off and the four-disc synchronous intermittent rotation assembly stops 10 rotations. The staff takes out the consolidated parts in each test room 3 in turn, groups them according to the radiation intensity level and marks them, and conducts performance testing. The performance testing includes recording the surface degradation characteristics of the consolidated parts, testing the attenuation of mechanical properties, and evaluating the changes in durability indicators. Based on the multi-intensity data obtained from the same batch of specimens, synchronous aging, and uniform environmental conditions, the staff directly analyzes the independent influence of radiation intensity variables on the aging rate.
