Description

Technical Field

[0001] This utility model relates to the field of experimental equipment, and more specifically, to a test device for simulating the cooling effect of road surface cooling coating. Background Technology

[0002] Asphalt pavements easily absorb large amounts of solar radiation in the high temperatures of summer, leading to increased pavement temperature and consequently affecting road lifespan and driving safety. To mitigate this problem, researchers have developed various coating materials and technologies to reduce the surface temperature of asphalt pavements. To obtain the effects of different coating materials and technologies on asphalt temperature, corresponding experiments are required. During the experiments, a light source needs to be designed to simulate sunlight to provide illumination conditions, thereby obtaining the differences in the cooling effects of different coatings on the asphalt surface temperature.

[0003] The inventors discovered during their research that the existing experimental devices have at least the following drawbacks:

[0004] The simulated light irradiation direction is fixed relative to the test specimen, which differs significantly from the actual sunlight irradiation conditions on the road surface. As a result, the accuracy of the obtained cooling effect is low, and its guiding significance for practical applications is limited. Utility Model Content

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0035] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0036] In existing technologies, to obtain data on the cooling effect of coating materials on asphalt pavements and thus better extend their service life, relevant light exposure tests are required. Typical light exposure test equipment includes a simulated light source and a support plate. The test specimen is placed on the support plate, and the simulated light source provides illumination, which shines onto the test specimen. During the test, the position of the simulated light source relative to the test specimen remains unchanged. Therefore, this differs from the actual light exposure conditions of asphalt pavements, resulting in low reliability of the test results.

[0037] In view of this, the designers have provided a test device for simulating the cooling effect of road surface cooling coatings, which can provide the test specimens with lighting conditions close to those under real conditions, reduce test errors, and improve the accuracy and reliability of test results.

[0038] Please refer to Figures 1-3 This embodiment provides a test device for simulating the cooling effect of a road surface cooling coating, including a base 100, a drive mechanism 200, and a light source simulation mechanism 300, wherein:

[0039] The base 100 is used to support the test specimen;

[0040] The drive mechanism 200 is mounted on the base 100;

[0041] The light source simulation mechanism 300 is mounted on the drive mechanism 200. The drive mechanism 200 is used to drive the light source simulation mechanism 300 to move relative to the base 100, so as to change the position of the light source simulation mechanism 300 relative to the test piece, thereby simulating the sunrise and sunset of the sun. The light source simulation mechanism 300 is used to irradiate the test piece placed on the base 100.

[0042] As described above, the working principle of the road surface cooling coating cooling effect simulation test device provided in this embodiment is as follows:

[0043] The test specimen is placed on the base 100, and the drive mechanism 200 and the light source simulation mechanism 300 are activated. The light source simulation mechanism 300 provides illumination to the test specimen, thereby simulating solar illumination conditions. Simultaneously, the drive mechanism 200 moves the light source simulation mechanism 300 relative to the test specimen. By changing the position of the light source simulation mechanism 300, the rising and setting positions of the sun throughout the day can be simulated, making the simulated illumination conditions of the test specimen closer to real-world illumination conditions. This results in more reliable data on the effect of the coating on the temperature of the test specimen, providing more meaningful guidance for practical applications.

[0044] The following embodiments illustrate the detailed structure of the road surface cooling coating cooling effect simulation test device of this application by way of example.

[0045] Please refer to Figure 1 In this embodiment, the optional road surface cooling coating cooling effect simulation test device includes a base 100, a drive mechanism 200, a light source simulation mechanism 300, and a temperature detection mechanism 400. The drive mechanism 200 is mounted on the base 100, the light source simulation mechanism 300 is mounted on the drive mechanism 200, and the temperature detection mechanism 400 is mounted on the base 100. The base 100 can position the test specimen, and the number of test specimens can be one or more. When there are multiple test specimens, comparative experiments can be conducted, improving test efficiency and the reliability of test results. The drive mechanism 200 can drive the light source simulation mechanism 300 to move relative to the base 100, simulating the changing position of the sun throughout the day. The light source simulation mechanism 300 can provide illumination to the test specimen, simulating sunlight irradiation conditions. The temperature detection mechanism 400 can acquire the temperature changes of the test specimen in real time.

[0046] Please refer to Figure 2 In this embodiment, optionally, the base 100 can be configured as a square plate. The base 100 has a first side 110, a second side 120, a third side 130, and a fourth side 140 connected end-to-end. The base 100 also has an upper plate surface and a lower plate surface that simultaneously connect the first side 110, the second side 120, the third side 130, and the fourth side 140, with the upper and lower plate surfaces facing each other. In application, the lower plate surface can be placed on a platform for positioning. Positioning grooves 150 are provided on the upper plate surface. The number of positioning grooves 150 can be one or more, designed as needed, and the multiple positioning grooves 150 can be independently arranged. For example, in this embodiment, the number of positioning grooves 150 is two, and the two positioning grooves 150 are arranged at intervals along the length direction of the base 100. Each positioning groove 150 can be a rectangular groove. Each positioning groove 150 can position one test piece. It should be understood that, depending on the test requirements, the number of positioning grooves 150 is not limited to two.

[0047] Optionally, to ensure that each positioning groove 150 can position test pieces of different sizes, a retractable clamping assembly 500 can be configured on at least one sidewall of the positioning groove 150. For example, in this embodiment, a retractable clamping assembly 500 is provided on each of the four sides of the positioning groove 150, and the area enclosed by the four retractable clamping assemblies 500 is the clamping area. The size of the clamping area enclosed by the four retractable clamping assemblies 500 is adjustable, thereby adapting to the positioning of test pieces of different sizes.

[0048] Please refer to Figure 2For example, the retractable clamping assembly 500 includes an elastic element 510 and a clamping plate 520. The elastic element 510 can be a spring. The clamping plate 520 can be a rectangular plate, etc. One end of the elastic element 510 is mounted on the side wall of the corresponding groove in the positioning groove 150, and the other end of the elastic element 510 is connected to the clamping plate 520. The plate surface of the clamping plate 520 is approximately perpendicular to the upper plate surface, and the plate surface of the clamping plate 520 is used to contact the test piece. During operation, since the elastic element 510 is in its natural state, the clamping area enclosed by the four clamping plates 520 is at its smallest size. When installing the test piece, the elastic element 510 is contracted to expand the clamping area. After the test piece is placed in the clamping area, the elastic element 510 has a rebound force, thereby clamping the test piece through the clamping plate 520. The operation is convenient and quick, and the application range is wide.

[0049] It should be understood that in other embodiments, the retractable clamping assembly 500 may be installed on only one sidewall of the positioning groove 150, or the retractable clamping assembly 500 may be installed on two sidewalls of the positioning groove 150, which may be two opposite sidewalls or two adjacent sidewalls, or the retractable clamping assembly 500 may be installed on three sidewalls of the positioning groove 150.

[0050] Please refer to Figure 1 It should be understood that at least one temperature detection mechanism 400 can be arranged in each positioning groove 150 to monitor the temperature of the test piece in different positioning grooves 150 in real time, thereby improving the accuracy of the test data. During assembly, the temperature detection mechanism 400 may include a temperature sensor, which can be installed on the bottom wall of the positioning groove 150. Multiple temperature sensors can be connected to a smart terminal to transmit temperature data to the smart terminal in real time, enabling real-time display of temperature parameters and facilitating data storage and analysis via the smart terminal.

[0051] Please refer to Figure 1 In this embodiment, optionally, the driving mechanism 200 includes a first driving component 210 and a second driving component 220, both of which are connected to the base 100. The light source simulation mechanism 300 is slidably engaged with both the first driving component 210 and the second driving component 220. The first driving component 210 is used to drive the light source simulation mechanism 300 to slide relative to the second driving component 220. The second driving component 220 is used to drive the light source simulation mechanism 300 to slide relative to the first driving component 210.

[0052] For example, the first drive assembly 210 includes a first motor 211 and a first arc-shaped slide rail 212. The first motor 211 is mounted on the first side 110 of the base 100, and the rotation axis of the first motor 211 is perpendicular to the first side 110. The first arc-shaped slide rail 212 can be a semi-circular bar, and the first arc-shaped slide rail 212 has a first slide rail 213 extending in its length direction. One end of the first arc-shaped slide rail 212 is mounted on the output shaft of the first motor 211, and the other end is rotatably connected to the second side 120. After the first motor 211 is started, it can drive the first arc-shaped slide rail 212 to rotate around the first axis 001, which is the axis of the first motor 211. The first arc-shaped slide rail 212 is driven by the motor to rotate, which provides flexible and reliable control. Moreover, both ends of the first arc-shaped slide rail 212 are positioned, resulting in high stability, smooth and reliable rotation, and a long service life.

[0053] Meanwhile, the second drive assembly 220 includes a second motor 221 and a second arc-shaped slide rail 222. The second motor 221 is mounted on the third side 130 of the base 100, and the rotation axis of the second motor 221 is perpendicular to the third side 130. The second arc-shaped slide rail 222 can be a semi-circular bar, and has a second slide rail 223 extending in its length direction. One end of the second arc-shaped slide rail 222 is mounted on the output shaft of the second motor 221, and the other end is rotatably connected to the fourth side 140. After the second motor 221 is started, it can drive the second arc-shaped slide rail 222 to rotate around the second axis 002, which is the axis of the second motor 221. The rotation of the second arc-shaped slide rail 222 driven by the motor is flexible and reliable. Moreover, both ends of the second arc-shaped slide rail 222 are positioned, resulting in high stability, smooth and reliable rotation, and a long service life.

[0054] After the first drive assembly 210 and the second drive assembly 220 are installed on the base 100, the first axis 001 and the second axis 002 are orthogonal, and the first arc-shaped slide rail 212 and the second arc-shaped slide rail 222 intersect. The center of the circle containing the first arc-shaped slide rail 212 overlaps with the center of the circle containing the second arc-shaped slide rail 222 and is located at the intersection of the first axis 001 and the second axis 002. At the same time, the first slide rail 213 and the second slide rail 223 intersect and are connected at the intersection position. The light source simulation mechanism 300 is positioned at the intersection position and is slidably engaged with the first arc-shaped slide rail 212 and the second arc-shaped slide rail 222. When the first arc-shaped slide rail 212 and the second arc-shaped slide rail 222 rotate, the intersection position changes continuously, thereby causing the position of the light source simulation mechanism 300 to change continuously, thus realizing that the light source simulation mechanism 300 moves relative to the test piece in the form of the sun rising in the east and setting in the west.

[0055] Please refer to Figure 1 and Figure 3In this embodiment, optionally, the light source simulation mechanism 300 includes a lamp body 310 and a mounting assembly. The mounting assembly is positioned at an intersection and slidably engages with both the first arc-shaped slide rail 212 and the second arc-shaped slide rail 222. The lamp body 310 is detachably mounted on the mounting assembly. Since the lamp body 310 does not directly engage with the slide rails, it is less prone to wear and damage, resulting in a long service life.

[0056] Optionally, the mounting assembly includes a mounting rod 320 and a detachment cap 330. The mounting rod 320 passes through both the first slide rail 213 and the second slide rail 223 at the intersection. The lamp body 310 is mounted on the end of the mounting rod 320 near the base 100, and the detachment cap 330 is mounted on the other end of the mounting rod 320. The detachment cap 330 can be threaded onto the mounting rod 320. When it is necessary to disassemble the lamp body 310, the detachment cap 330 can be unscrewed from the mounting rod 320 first, then the mounting rod 320 can be pulled downward from the first slide rail 213 and the second slide rail 223, and then the lamp body 310 can be removed from the mounting rod 320.

[0057] It should be understood that the lamp body 310 can be screwed onto the mounting rod 320. A rechargeable battery can be installed on the lamp body 310 to improve resource utilization.

[0058] The road surface cooling coating cooling effect simulation test device provided in this embodiment allows for the placement of a corresponding number of test specimens into the corresponding positioning grooves 150 as needed. The retractable clamping assembly 500 within the positioning grooves 150 then clamps and positions the test specimens, ensuring their stability relative to the base 100. Subsequently, the first motor 211 and the second motor 221 are activated. The first motor 211 drives the first arc-shaped slide rail 212 to rotate around the first axis 001, and the second motor 221 drives the second arc-shaped slide rail 222 to rotate around the second axis 002. This causes the light source simulation mechanism 300 to undergo a combined motion. The light source simulation mechanism 300 can simulate the changing position of the sun rising in the east and setting in the west, providing more realistic lighting conditions for the test specimens and resulting in higher accuracy of the obtained test results.

[0059] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
