Description

Technical Field

[0001] This utility model relates to the field of permafrost engineering, and in particular to a composite device for monitoring the practical performance of heat-reflective coatings in high-altitude and cold regions. Background Technology

[0002] In recent years, with the continuous advancement of urbanization, the mileage and grade of roads within and between cities have been constantly improving. Asphalt concrete pavement, due to its excellent comprehensive performance, has been widely used in various engineering environments and working conditions. However, regardless of the type of dark asphalt pavement, it has strong heat absorption, heat accumulation, and heat storage characteristics, leading to significant urban heat island effects, high-temperature rutting, and freeze-thaw damage to roadbeds in cold regions, among other problems. How to alleviate or prevent engineering defects and thermal environment problems caused by asphalt pavement has become an urgent engineering and technical problem to be solved. Utilizing road heat reflection technology can significantly reduce the amount of solar radiation absorbed by the road surface, reduce the release of sensible heat from the road surface, alleviate the urban heat island effect, reduce rutting damage, and improve the thermal stability of the roadbed. In addition, this technology can also reduce the electricity demand for nighttime lighting in urban lanes and solve the problem of difficult road lighting in remote areas.

[0003] However, although heat reflective technology has achieved certain results in mitigating the urban heat island effect and improving the cooling effect of road surfaces, its research in road and pavement engineering in high-altitude and cold regions is still in the exploratory stage. This is mainly because the scale of highway construction in high-altitude and cold regions is far smaller than that in densely populated urban areas, and the application of this technology has only gradually gained attention from scholars and engineers with the development of highway construction in recent years. Roadbeds in high-altitude and cold regions are subjected to the coupled effects of vehicle loads, environmental forces, and extreme climate conditions, placing extremely stringent requirements on the performance of materials required for heat reflective technology. Based on current experiments and research, while tested heat reflective coatings can reduce the impact of solar radiation on roads to some extent, existing research results lack unified proportioning and evaluation standards, making it impossible to conduct large-scale proportioning and strength tests in a short period of time, and unable to determine which material proportions achieve the best effect within a certain timeframe, including conditions such as heat reflectivity, aging resistance, and wear resistance. Therefore, designing a composite device suitable for testing the practicality of heat reflective coatings in high-altitude and cold regions for large-scale monitoring of the effects of heat reflective coatings is particularly important. This device can not only systematically compare the effects of coatings with different ratios and materials under the same temperature and time conditions, but also additionally monitor the temperature changes, solar radiation intensity, anti-aging performance and wear resistance of the coatings, providing reliable data support for the application of heat-reflective coatings in high-altitude and cold regions. Utility Model Content

[0004] This invention addresses the problems of low efficiency in proportioning and screening, insufficient durability testing, and limited monitoring methods in the application of existing heat-reflective coatings in high-altitude and cold regions. It provides a composite device for monitoring the practical performance of heat-reflective coatings in these areas. The device enables systematic comparative testing of the performance of various heat-reflective coatings and improves the comprehensiveness and accuracy of data acquisition by integrating multiple monitoring devices.

[0005] This utility model provides a composite device for monitoring the practical performance of heat-reflective coatings in high-altitude and cold regions, including a base, a retractable support, a structural frame, a slide, a guide rail, experimental plates, wheels, and a data acquisition box. The base is a stepped structure, higher in the middle and lower on both sides. The lower sides each have three screw holes for connecting to the ground and fixing the base. The higher part has five square holes, each with a screw hole in the center, for connecting with the retractable support. The retractable support consists of four retractable square tubes, each formed by two interlocking square tubes of different sizes. The large and small square tubes have continuous screw holes on both sides, and their height is adjusted and fixed using bolts and nuts. The structural frame consists of four grooved steel pipes joined end-to-end to form a rectangular frame. The interlocking parts have threaded holes and are fixed with bolts and nuts. The slide is an arch-shaped I-beam structure, with two threaded holes on each of its ribs. The lower threaded hole connects to the small square steel of the retractable support, and the upper threaded hole forms an embedded structure with the structural frame and is fixed with bolts. The guide rail is a U-shaped iron rod with pulleys at both ends. The pulleys are embedded in grooves in the structural frame, and screws are provided on the outside of the guide rail for adjusting the tightness. The experimental plate has a circular groove in the center for filling with heat-reflective coating for monitoring. After the experimental plate is inserted into the guide rail, it remains stable and does not shift. The roller consists of a main shaft, rollers, and end-slot blocks, and is used to test the wear resistance of the coating.

[0006] Furthermore, the data acquisition box includes a rechargeable battery, a data acquisition instrument, a solar panel, a temperature sensor, and a solar radiation meter. The rechargeable battery is connected to the data acquisition instrument to power it, and the solar panel is connected to the battery to maintain voltage stability. The temperature sensor and solar radiation meter are respectively connected to the data acquisition instrument to collect real-time data on the coating's temperature and solar radiation intensity over a set period of time.

[0007] Specifically, this invention uses a high-definition camera mount to install a high-definition camera for periodically capturing images of the coating surface. The images captured by the high-definition camera can be used to evaluate the coating's anti-aging performance through RGB analysis. Furthermore, the solar radiation meter is fixed to the top of the structural frame via a circular slot, ensuring its perpendicularity to the frame and allowing for adjustment of its position and height as needed.

[0008] Furthermore, this invention enables remote data acquisition through wireless transmission equipment, ensuring accurate monitoring data can be obtained even in harsh environments such as high-altitude and frigid regions. The solar panel continuously charges the battery, guaranteeing the stability of the equipment during long-term operation.

[0009] The beneficial effects of this invention are that, through the above technical solution, a systematic comparative test of various heat-reflective coatings under the same temperature and time conditions is achieved, significantly improving the efficiency of formulation and screening. The device integrates temperature monitoring, solar radiation monitoring, anti-aging performance monitoring, and wear resistance testing functions, enabling a comprehensive evaluation of the overall performance of heat-reflective coatings. The combination of wireless transmission equipment and a solar power supply system ensures real-time data acquisition and stable equipment operation, providing reliable technical support for the application of heat-reflective coatings in high-altitude and cold regions.

[0017] This invention provides a composite device for monitoring the practical performance of heat-reflective coatings in high-altitude and cold regions. This device enables systematic comparative testing of the performance of various heat-reflective coatings and improves the comprehensiveness and accuracy of data acquisition by integrating multiple monitoring devices. This invention is applicable to permafrost engineering in high-altitude and cold regions, particularly in road construction in areas such as the Qinghai-Tibet Plateau, and can effectively monitor and evaluate the comprehensive performance of heat-reflective coatings, including heat reflectivity, anti-aging properties, and wear resistance. The specific embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0018] First, place all parts and connecting rods of this utility model in an open area, prepare the required number of bolts and nuts, and additionally prepare wrenches, screwdrivers, and other tools. Specifically, the base 10 has a stepped structure that is higher in the middle and lower on both sides. Three screw holes are provided on each of the lower sides for connecting to the ground to fix the base. The higher part has five square holes, each with a screw hole in the center, which can be bolted together with the telescopic support 11 for fixation. The structural design of the base 10 ensures the stability of the device and prevents displacement under adverse weather conditions.

[0019] Next, place the two bases 10 on a relatively flat surface, ensuring the distance between them matches the distance to the structural frame 14. Use 12 long screws, which are connected to the ground for stability. To prevent the detection device from shifting due to severe weather, the bases 10 must be firmly fixed to the ground. The fixing steps for the bases 10 are as follows: First, use a wrench to pass the screws through the screw holes in the bases 10, then screw the screws into the ground, ensuring a tight fit between the bases 10 and the ground.

[0020] Based on the fixed base 10, four telescopic supports 11 are placed in the corresponding holes of the base 10 as needed. In most cases, the telescopic supports 11 are calibrated with two high and two low supports, each height positioned on one side of the base 10. Each telescopic support 11 consists of four telescopic square tubes, each formed by two interlocking square tubes of different sizes. Both sides of the large and small square tubes have continuous threaded holes of the same size. The height is adjusted and fixed using bolts and nuts. The specific steps are: pass the bolts through the continuous threaded holes of the large and small square tubes, then screw in the nuts, and tighten the nuts to fix the height of the support. At this point, the support components of the observation frame are installed.

[0021] The top of the telescopic support 11 has an additional pre-drilled screw hole, which can be tightly fitted with the hole in the slide 12. The slide 12 has an arch-shaped I-beam structure, with two threaded holes on the upper and lower sides of its ribs. The lower threaded hole engages with the inner small square steel of the telescopic support 11, while the upper threaded hole can be further secured by bolts after the structural frame 14 and the slide 12 form an embedded structure, ensuring that the frame does not slide freely. The installation steps for the slide 12 are as follows: First, align the lower threaded hole of the slide 12 with the inner small square steel of the telescopic support 11, then use a bolt to pass through the threaded hole and screw in the nut to ensure a secure connection between the slide 12 and the telescopic support 11. Next, align the upper threaded hole of the slide 12 with the structural frame 14, use a bolt to pass through the threaded hole and screw in the nut to ensure a secure connection between the slide 12 and the structural frame 14.

[0022] The structural frame 14 consists of four grooved steel pipes joined end-to-end to form a rectangular frame. Threaded holes are provided at the joints for securing with bolts and nuts. The installation steps for the structural frame 14 are as follows: First, join the four steel pipes end-to-end, ensuring the grooves are aligned. Then, pass bolts through the threaded holes and screw in nuts to ensure a secure connection. Depending on the required number of guide rails 15, any corner of the structural frame 14 can be opened to add or remove rails. Specifically, to increase the number of guide rails 15, open one corner of the structural frame 14, add a steel pipe, and then secure it with bolts and nuts; similarly, to reduce the number of guide rails 15, open one corner of the structural frame 14, remove a steel pipe, and then secure it with bolts and nuts. This allows for flexible adjustment of the structural frame 14's dimensions to accommodate different numbers of experimental panels 18.

[0023] The guide rail 15 is a U-shaped iron rod with pulleys at both ends. The pulleys can be fitted into the grooves of the structural frame 14. Screws are provided on the outside of the guide rail 15 for adjusting the tightness. The installation steps of the guide rail 15 are as follows: First, align the pulleys of the guide rail 15 with the grooves of the structural frame 14, and then insert the guide rail 15 into the groove, ensuring that the pulleys are fully embedded. Next, determine the number of guide rails 15 according to the size of the experimental plate 18. If there are not enough guide rails 15, the guide rails 15 may wobble from side to side. Therefore, additional screws need to be added to the outside of the guide rails 15 to adjust the tightness of the contact between the guide rail 14 and the frame 15. Specifically, the screws are passed through the outside of the guide rail 15 and screwed into the grooves of the structural frame 14. The position of the guide rail 15 is fixed by tightening the screws to ensure that it will not loosen.

[0024] The experimental panel 18 has a circular groove 19 at its center, which is mainly used for filling heat-reflective coating for monitoring. The experimental panel 18 can be inserted between the two guide rails 15 without sliding freely, and multiple panels will form a tight structure without unnecessary displacement. The installation steps of the experimental panel 18 are as follows: First, the coating to be monitored is pre-poured into the circular groove 19 of the panel 18. After it solidifies, the panels 18 can be placed between the guide rails 15 in a certain order. Ensure that all panels 18 are in close contact and do not move, thus ensuring stability. If additional fixing is required, bolts can be used to fix it through the bolt connection fixing holes 25 on the experimental panel 18.

[0025] The roller 21 consists of three parts: a main shaft, a roller, and end slots. The roller and the main shaft fit together tightly, and relevant parts can be replaced according to the required testing. This part mainly tests the wear resistance of the coating and observes the surface condition of the coating. The installation steps of the roller 21 are as follows: First, pass the main shaft of the roller 21 through the end slots to ensure that the roller 21 fits tightly with the main shaft. Then, place the roller 21 on the surface of the test plate 18, and adjust the height of the roller 21 as needed to ensure that the roller 21 can evenly roll the surface of the test plate 18. Through the continuous rolling of the roller 21, the wear condition of the coating surface can be observed, and its wear resistance performance can be evaluated.

[0026] The data acquisition box 9 consists of a rechargeable battery 1, a data acquisition instrument 4, a solar panel 2, a temperature sensor 33, and a solar radiation meter 16. The rechargeable battery 1 is directly connected to the data acquisition instrument 4 to power it, and the solar panel 2 is connected to the battery 1 to maintain voltage stability. The temperature sensor 33 and the solar radiation meter 16 are respectively connected to the data acquisition instrument 4 to collect the temperature status and solar radiation intensity of the coating in real time at a set time.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
