Description

Technical Field

[0001] This utility model relates to the field of snow melting and ice removal technology for roads in high-altitude permafrost areas, and in particular to a snow melting and ice removal device for roads in high-altitude permafrost areas. Background Technology

[0002] High-altitude permafrost regions refer to areas located in cold climate zones where temperatures remain below zero degrees Celsius for extended periods, and most areas have a permafrost layer, meaning the soil is frozen for most of the year. In high-altitude permafrost regions, road snow and ice melting devices are commonly used. These devices involve burying electric heating equipment, such as heating wires or heating films, in the road surface to melt the snow and ice through electric current heating.

[0003] Existing technologies, such as the utility model patent with publication number CN217758172U, disclose a snow and ice removal device. This patent includes a water tank, an outlet pipe, a return pipe, a snow-melting pipe, and a pump body. The water tank is used to store water and is located underground. Both the outlet pipe and the return pipe are connected to the water tank. The snow-melting pipe is located below the road surface and above the water tank, with its two ends connected to the outlet pipe and the return pipe, respectively. The pump body is connected to the outlet pipe and is used to pump water from the water tank through the outlet pipe into the snow-melting pipe and back to the water tank through the return pipe. In this utility model, the underground temperature is higher than the road surface temperature. Therefore, geothermal energy is used to heat the water in the water tank. The pump body then pumps the water into the snow-melting pipe. The road surface carries away the heat from the water in the snow-melting pipe, thus heating the road surface. The heated road surface melts the snow and ice, achieving the effect of snow and ice removal.

[0004] During the construction of road snow melting and de-icing projects, it was found that traditional road de-icing methods are mainly divided into two categories. One is to spray de-icing agents on the road surface. However, de-icing agents can cause environmental problems such as corrosion and soil salinization. Laying pipeline de-icing systems is expensive and difficult to implement on a large scale. The other is to lay pipeline de-icing systems in the roadbed. Metal pipes are laid under the road surface layer, and a heat medium, such as oil or water, is introduced to heat the road and melt the snow. However, in permafrost areas, this method can cause the permafrost roadbed to melt, resulting in roadbed subsidence and road damage. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology where the laying of pipes and other heating snow-melting and de-icing devices causes the frozen soil subgrade to melt, resulting in road subsidence and other road defects.

[0006] To solve the above-mentioned technical problems, this utility model provides a road snow melting and ice de-icing device for high-altitude permafrost areas, including: a permafrost roadbed and an asphalt pavement. The asphalt pavement is located on the upper surface of the permafrost roadbed. A heat insulation system is provided on the side of the asphalt pavement and the permafrost roadbed that are close to each other. A snowfall and ice freezing early warning system and a heating system are provided on the side of the heat insulation and heat preservation anti-radiation aluminum film that are close to each other.

[0007] The effects achieved by the above components are as follows: through the optimized layout and synergistic effect of the snow and ice warning system, heating system and heat insulation system in the road structure layer, the rapid, accurate and efficient removal of ice and snow on the road surface is realized, while effectively isolating the heat of melting ice from the permafrost subgrade below, thus protecting the stability of the permafrost.

[0008] Preferably, the snowfall and icing early warning system includes a road surface temperature sensor, a water immersion sensor, and a signal processor.

[0009] The effect achieved by the above components is as follows: the snowfall and icing early warning system achieves accurate, real-time and early warning of the risk of icing on road surfaces in high-altitude permafrost areas through the coordinated monitoring of road surface temperature sensors and water immersion sensors, and intelligent analysis and judgment by signal processor.

[0010] Preferably, the heating system includes a nanothermal rod, a current regulator, and a roadbed temperature sensor.

[0011] The aforementioned components achieve the following effect: the heating system, through the efficient directional heating of the nano heat rods, the precise power control of the current regulator, and the key temperature monitoring and feedback of the roadbed temperature sensor, together realizes the rapid and efficient removal of ice and snow from the road surface.

[0012] Preferably, the heat insulation system includes a heat-insulating and anti-radiation aluminum film, which is located on the upper surface of the frozen soil subgrade.

[0013] The effects achieved by the above components are: by reflecting heat upwards and by keeping it warm, the de-icing efficiency of the upper heating system is significantly improved, the overall energy consumption is reduced, and it also has auxiliary moisture-proof and water-proof functions.

[0014] Preferably, the upper surface of the heat-insulating and anti-radiation aluminum film is provided with slots corresponding to the positions of the road surface temperature sensor and the water immersion sensor, and the inner walls of the two slots are respectively engaged with the bottom surfaces of the road surface temperature sensor and the water immersion sensor.

[0015] The effect achieved by the above-mentioned components is that the slots can effectively protect the positions of the road surface temperature sensor and water immersion sensor on the lower surface of the asphalt pavement, preventing positional displacement.

[0016] Preferably, the upper surface of the heat-insulating and heat-preserving anti-radiation aluminum film is provided with an inlay groove, the inner wall of the inlay groove is engaged with the nano heat rod, and a protective shell is fixedly connected to the surface of the roadbed temperature sensor.

[0017] The aforementioned components achieve the following effects: the nano-thermal rods can be effectively fixed by the embedding groove, while the protective shell can protect the roadbed temperature sensor.

[0018] Compared with related technologies, the snow melting and ice-de-icing device for roads in high-altitude permafrost areas provided by this utility model has the following beneficial effects:

[0019] This utility model provides a road snow melting and ice-melting device for high-altitude permafrost regions. During the snow melting and ice-melting operation in high-altitude permafrost regions, the heat-insulating and anti-radiation aluminum film in the heat insulation system can effectively isolate the heat of the nano-heating rods of the heating system from being transferred to the frozen soil subgrade, reducing the heat loss of the nano-heating rods and improving the efficiency of melting snow and ice on the road surface. At the same time, the heating system adjusts the heating power of the heating rods in real time through temperature sensors buried in the frozen soil subgrade to prevent the frozen soil subgrade from melting due to excessive temperature and causing road damage.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] Please see Figures 1 to 5 The present invention provides a road snow melting and ice de-icing device for high-altitude permafrost areas, comprising: a permafrost roadbed 1 and an asphalt pavement 3. The asphalt pavement 3 is located on the upper surface of the permafrost roadbed 1. A heat insulation system is provided on the side of the asphalt pavement 3 and the permafrost roadbed 1 that are close to each other. A snowfall and ice freezing early warning system 13 and a heating system 14 are provided on the side of the heat insulation and heat preservation anti-radiation aluminum film 2 and the side of the asphalt pavement 3 that are close to each other.

[0029] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The snow and ice warning system 13 includes a road surface temperature sensor 5, a water immersion sensor 4, and a signal processor 12. The heating system 14 includes a nano heat rod 6, a current regulator 11, and a roadbed temperature sensor 7. The heat insulation system includes a heat-insulating and heat-reflecting aluminum film 2. The heat-insulating and heat-reflecting aluminum film 2 is located on the upper surface of the frozen soil roadbed 1. The upper surface of the heat-insulating and heat-reflecting aluminum film 2 has slots 9 at the positions corresponding to the road surface temperature sensor 5 and the water immersion sensor 4. The inner walls of the two slots 9 are respectively engaged with the bottom surfaces of the road surface temperature sensor 5 and the water immersion sensor 4. The upper surface of the heat-insulating and heat-reflecting aluminum film 2 has an inlay groove 10. The inner wall of the inlay groove 10 is engaged with the nano heat rod 6. A protective shell 8 is fixedly connected to the surface of the roadbed temperature sensor 7.

[0030] The working principle of the snow melting and ice de-icing device for roads in high-altitude permafrost areas provided by this utility model is as follows: First, during the roadbed construction process, a ground temperature sensor is buried at a certain distance from the top surface of the permafrost roadbed 1. After the roadbed construction is completed, a heat-insulating and heat-reflecting aluminum film 2 is laid on it. At the same time, a nano-heating rod 6 is first laid on the heat-insulating and heat-reflecting aluminum film 2. Then, a water immersion sensor 4 and a road surface temperature sensor 5 are buried in the curb strip on one side of the asphalt pavement 3. After the signal processor 12 receives the signals from the water immersion sensor 4 and the road surface temperature sensor, it sends a signal to the current regulator 11 to make the nano-heating rod 6 start to heat up. The temperature sensor in the roadbed transmits a signal to the signal processor 12. When the temperature in the roadbed reaches a certain limit value, it is adjusted. The signal processor 12 sends a signal to the current regulator 11 to adjust the current magnitude, thereby adjusting the power of the nano-heating rod 6 and reducing the heating temperature of the nano-heating rod 6.
