Description

Terrain-adjustable cooling and temperature control multi-functional micro-adjustment support rod Technical Field

[0001] This invention relates to the field of geotechnical engineering technology, specifically to a multi-functional fine-adjustment support rod for variable terrain cooling and temperature control. Background Technology

[0002] In northern airport runway environments, there exists a "pot lid effect," where in seasonally frozen soil regions, water vapor migrates upwards under the influence of a temperature gradient, condensing on the low-temperature, impermeable surface layer and preventing its escape. In contrast, at airports in southwestern mountainous areas, summer surface temperatures and humidity are high. Under the influence of a temperature gradient and capillary action, water vapor migrates towards the shallow soil-rock interface, accumulating downwards under the influence of gravity at the slope interface. This phenomenon is called the "reverse pot lid effect."

[0003] In practical engineering, the "bowl lid effect" can cause water accumulation, frost heave, or settlement under airport runways and paved roads, posing a significant threat to airport or road safety. The "reverse bowl lid effect," on the other hand, occurs when water vapor sublimates at the shallow soil-rock interface and then flows downwards under gravity. Once it accumulates to a certain amount, it causes wetting of adjacent soil layers, leading to overall slope slippage and damage.

[0004] In existing technologies, corresponding experimental devices have been developed and considerable research has been conducted on the water vapor migration patterns under the "bowl effect" in seasonally frozen soil regions of northern China, preliminarily revealing the migration and accumulation mechanisms of gaseous water in closed or semi-closed soil bodies. However, for the "reverse bowl effect" occurring in typical scenarios such as airports in the southwestern mountainous areas, there is currently a lack of specialized experimental devices and systematic research. Furthermore, the testing of water migration at the soil-rock interface under the reverse bowl effect requires experimental control of both topographic variations and soil-rock interface temperature, which existing devices cannot meet. Summary of the Invention

[0005] Therefore, it is necessary to provide a multi-functional fine-tuning support rod for variable terrain cooling and temperature control, which addresses the problem that existing experimental devices cannot meet the experimental requirements of variable terrain control and soil-rock interface temperature control.

[0006] A multi-functional fine-tuning support rod for terrain-changing cooling and temperature control includes: a terrain control component, including a support rod, which is installed on a test chamber and the support rod adjusts the terrain of the soil-rock interface by adjusting its length extending into the test chamber; and a cold temperature control component, including a heat absorption tube and a refrigeration assembly, wherein the heat absorption tube is coiled around the support rod and the refrigeration assembly is used to introduce refrigerant into the heat absorption tube.

[0007] In one embodiment, each set of terrain control components includes two support rods, and the heat absorption tubes coiled on the two support rods are interconnected. After the refrigerant provided by the refrigeration assembly enters one of the heat absorption tubes, it circulates back to the refrigeration assembly through the adjacent heat absorption tube.

[0008] In one embodiment, the two support rods of each set of terrain control components are connected as a whole by a connecting frame.

[0009] In one embodiment, the refrigeration assembly includes a compressor, a condenser, and a capillary copper tube. The compressor compresses the refrigerant and supplies it to the condenser. The condenser cools the refrigerant and supplies it to the capillary copper tube. The capillary copper tube depressurizes and cools the refrigerant and supplies it to the heat absorption tube. The refrigerant in the heat absorption tube is circulated back to the compressor.

[0010] In one embodiment, the refrigeration assembly further includes a liquid guide pipe and a gas return pipe. The refrigerant provided by the capillary copper tube enters the heat absorption tube through the liquid guide pipe, and the refrigerant after heat exchange is circulated back to the compressor through the gas return pipe. Valves are installed on both the liquid guide pipe and the gas return pipe.

[0011] In one embodiment, the test chamber is provided with a mounting hole, and the support rod is slidably installed in the mounting hole. The sliding of the support rod in the mounting hole is used to adjust the length of the support rod extending into the test chamber.

[0012] In one embodiment, the test chamber is provided with a mounting hole, and the support rod is fixedly installed in the mounting hole. The extension and retraction adjustment of the support rod extends into the test chamber to a certain length.

[0013] In one embodiment, the cold temperature control component further includes a temperature sensor for detecting the temperature of the soil-rock interface.

[0014] In one embodiment, two sets of fixing nuts are threaded onto the support rod, with the two sets of fixing nuts located on the inner and outer sides of the test chamber, respectively.

[0015] In one embodiment, the support rod is located at the end of the body outside the test chamber and is provided with an adjusting head for adjusting the support rod.

[0016] The aforementioned multi-functional fine-tuning support rod for variable terrain cooling and temperature control adjusts the undulation of the soil-rock interface by changing the length of the support rod extending into the test chamber, thereby adjusting the terrain of the soil-rock interface to meet the requirements of variable terrain control. Simultaneously, the heat exchange tube can exchange heat with the soil-rock interface, absorbing heat from the interface and bringing its temperature closer to the actual temperature of the soil-rock interface, thus fulfilling the experimental requirements for soil-rock interface temperature control.

[0023] Please refer to Figure 1. In one embodiment, the multi-functional fine-tuning support rod for variable terrain cooling and temperature control includes a terrain control component 10 and a cold temperature control component 20.

[0024] Please refer to Figures 2 and 3 together. The terrain control component 10 includes a support rod 11, which is installed on the test chamber 1. The support rod 11 adjusts the undulation of the soil-rock interface by adjusting the length of the support rod 11 extending into the test chamber 1, thereby adjusting the terrain of the soil-rock interface.

[0025] Specifically, after the support rod 11 is installed inside the test chamber 1, the support rod 11 is connected to the temperature guide plate 2, and two adjacent temperature guide plates 2 are hinged to each other. A rock plate 3 is provided on the temperature guide plate 2. By adjusting the length of the support rod 11 extending into the test chamber 1, the angle of the temperature guide plate 2 can be adjusted to adjust the topography of the soil-rock interface.

[0026] The temperature control component 20 includes a heat-absorbing pipe 21 and a refrigeration assembly 22. The heat-absorbing pipe 21 is coiled around the support rod 11, and the refrigeration assembly 22 is used to introduce refrigerant into the heat-absorbing pipe 21. After the refrigerant is introduced into the heat-absorbing pipe 21, the temperature of the heat-absorbing pipe 21 is relatively low. The heat-absorbing pipe 21 can exchange heat with the soil-rock interface, absorbing heat from the soil-rock interface and making the temperature of the soil-rock interface close to the actual temperature of the soil-rock interface, thus meeting the experimental requirements for soil-rock interface temperature control.

[0027] In this embodiment, the number of terrain control components 10 is the same as the number of temperature-conducting plates 2, with each terrain control component 10 connected to one temperature-conducting plate 2. In one embodiment, each group of terrain control components 10 includes two support rods 11, which work together on the same temperature-conducting plate 2. Each support rod 11 has a heat-absorbing tube 21 wound around it, and the heat-absorbing tubes 21 wound on the two support rods 11 are interconnected. The refrigerant provided by the refrigeration assembly 22 enters one of the heat-absorbing tubes 21 and then circulates back into the refrigeration assembly 22 through the adjacent heat-absorbing tube 21. By designing two heat-absorbing tubes 21 for each group of terrain control components 10, the temperature control effect can be enhanced while facilitating refrigerant circulation.

[0028] In one embodiment, the heat-conducting plate 2 can be a heat-conducting copper plate, and the heat-absorbing pipe 21 can be a heat-absorbing copper pipe, which facilitates heat exchange. The two support rods 11 of each set of terrain control components 10 are connected by a connecting frame 12. The connecting frame 12 can connect the two support rods 11 into a whole, maintaining the stability of the support for the heat-conducting plate 2. At the same time, the connecting frame 12 can also facilitate the interconnection of the two heat-absorbing pipes 21.

[0029] In one embodiment, the test chamber 1 is provided with a mounting hole 4, and the support rod 11 is slidably installed in the mounting hole 4. The sliding of the support rod 11 within the mounting hole 4 adjusts the length of the support rod 11 extending into the test chamber 1, thereby altering the topography of the soil-rock interface. Of course, the length of the support rod 11 extending into the test chamber 1 can also be achieved in other ways. For example, the support rod 11 can be fixedly installed in the mounting hole 4, or the support rod 11 itself can be telescopic, and the telescopic adjustment of the support rod 11 adjusts the length extending into the test chamber 1. Specifically, the support rod 11 can be an electrically operated telescopic rod, etc.

[0030] It is understood that in other embodiments, the length of the support rod 11 extending into the test chamber 1 can be adjusted in other ways. For example, when each set of terrain control components 10 includes only one support rod 11, the support rod 11 can be rotatably installed in the mounting hole 4, and the length of the support rod 11 extending into the test chamber 1 can be adjusted by rotating the support rod 11.

[0031] In one embodiment, two sets of fixing nuts 13 are threaded onto the support rod 11, with the two sets of fixing nuts 13 located on the inner and outer sides of the test chamber 1, respectively. After adjusting the length of the support rod 11 extending into the test chamber 1, the two sets of fixing nuts 13 are rotated to fit against the inner and outer walls of the test chamber 1, thus clamping and fixing it to the test chamber 1. This fixes the length of the support rod 11 extending into the test chamber 1 and prevents the support rod 11 from loosening from the test chamber 1.

[0032] In one embodiment, the end of the support rod 11 located outside the test chamber 1 is provided with an adjusting head 14 for adjusting the support rod 11. The length of the support rod 11 extending into the test chamber 1 can be easily adjusted by using the increased diameter adjusting head 14. For example, by holding the adjusting head 14, the support rod 11 can be slid within the mounting hole 4 to adjust its position.

[0033] In one embodiment, the refrigeration assembly 22 includes a compressor 221, a condenser 222, and a capillary copper tube 223. The compressor 221 compresses the refrigerant. During compression, the refrigerant temperature rises to 90°C and the pressure increases to 8 Bar. This high-temperature, high-pressure gas is then delivered to the condenser 222. As the high-temperature gas passes through the condenser 222, it exchanges heat with the external environment. Due to the low ambient temperature, the refrigerant begins to cool slowly. After cooling in the condenser 222, the refrigerant gas becomes liquid, and its temperature drops to 45°C. The cooled refrigerant then enters the capillary copper tube 223, which has a diameter of 1 mm. The capillary copper tube 223 converts the high-pressure refrigerant to a low-pressure state, completely cooling the refrigerant. The degree of temperature reduction during condensation is determined by the length of the capillary copper tube 223; a longer tube results in a lower temperature and a better condensation effect. Finally, the capillary copper tube 223 supplies the refrigerant to the heat absorber tube 21, where heat exchange occurs between the heat absorber tube 21 and the external environment, achieving a cooling effect. After heat exchange, the refrigerant turns back into a gas and is recycled back to compressor 221 to start the refrigeration process again.

[0034] In one embodiment, the refrigeration assembly 22 further includes a liquid guide pipe 224 and a return pipe 225. The refrigerant supplied by the capillary copper tube 223 enters the heat absorption tube 21 through the liquid guide pipe 224, and the refrigerant after heat exchange circulates back to the compressor 221 through the return pipe 225. In order to control the refrigerant circulation, valves 226 are installed on both the liquid guide pipe 224 and the return pipe 225 to control the opening and closing of the liquid guide pipe 224 and the return pipe 225.

[0035] In one embodiment, the temperature control component 20 further includes a temperature sensor 23 for detecting the temperature of the soil-rock interface. When the temperature of the soil-rock interface is lower than the expected value, the compressor 221 is controlled to reduce its speed or stop working. When the temperature of the soil-rock interface is higher than the expected value, the temperature sensor controls the compressor 221 to work or increase its operating speed, thereby achieving the purpose of controlling the temperature.

[0036] The aforementioned multi-functional fine-tuning support rod for variable terrain cooling and temperature control adjusts the undulation of the soil-rock interface by adjusting the length of the support rod 11 extending into the test chamber 1, thereby achieving terrain adjustment of the soil-rock interface and meeting the requirements for variable terrain control. Simultaneously, the heat exchange tube 21 can exchange heat with the soil-rock interface, absorbing heat from the interface to bring its temperature closer to the actual temperature, thus fulfilling the experimental requirement for soil-rock interface temperature control. Furthermore, the support rod 11 can simultaneously achieve variable terrain control and soil-rock interface temperature control, significantly saving space and reducing energy consumption, making it suitable for long-term experimental operations.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
