Technical Field
[0001] This utility model relates to the field of tunnel engineering, specifically a snow removal and treatment device for cold-region tunnels based on infrared thermal radiation. Background Technology
[0002] In recent years, the construction of mountain highway tunnels in my country has seen a significant increase in both the number and length of tunnels. In addition, more and more mountain tunnels are being built in different regions. Tunnels located in cold regions are mostly below 0°C, with low temperatures and frequent snowfall.
[0003] A tunnel entrance refers to the transition point between a tunnel and a highway. During snowfall, tunnels are generally free of snow, offering relatively good driving conditions. However, the temperature difference between the inside and outside of the tunnel entrance—higher inside and lower outside—makes it easy for the inner walls of the tunnel to freeze, which in turn causes the road surface to become icy. Outside the tunnel, snowfall easily leads to snow and ice accumulation on the road, resulting in poor road conditions. When approaching a tunnel exit, many drivers fail to quickly and accurately recognize this situation and often continue driving at a higher speed without reducing speed, greatly increasing the risk of traffic accidents.
[0004] Currently, the main approach is to apply de-icing agents to the tunnel entrances after snowfall, relying on manual processing. However, this method is subject to weather and road conditions, resulting in delayed processing. Furthermore, de-icing agents can accelerate the corrosion of metal components in the tunnel, damage the concrete structure, and even affect the tunnel's durability. Therefore, there is an urgent need for a snow removal and treatment method for tunnels in cold regions to solve these problems. Utility Model Content
[0005] To address the problem of poor road conditions caused by snow and ice accumulation at tunnel entrances in cold regions, this invention provides a snow removal and treatment device for cold-region tunnels based on infrared thermal radiation, which removes snow from tunnel entrances without causing corrosion to the tunnel.

[0008] The radiant heating device is connected to the mobile device, which is installed at the tunnel entrance. The mobile device can move the radiant heating device so that the radiant heating area of the radiant heating device is located in the snow-covered area at the tunnel entrance.
[0009] The detection device is installed at the tunnel entrance to detect the state of snow accumulation.
[0010] The radiant heating device, the moving device, and the detection device are respectively connected to the control unit. The control unit controls the working status of the moving device and the radiant heating device according to the feedback data of the detection device to melt the snow and / or ice at the tunnel entrance.
[0011] Preferably, the radiant heating device is an infrared spotlight, and multiple infrared spotlights form an infrared spotlight group, which is arranged at intervals along the circumference of the tunnel entrance.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.
[0031] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.
[0032] A snow removal and treatment device for tunnels in cold regions based on infrared thermal radiation includes a radiation heating device, a moving device, a detection device, and a control unit.
[0033] The radiant heating device is connected to a mobile device, which is installed at the tunnel entrance. The mobile device can move the radiant heating device so that the radiant heating area of the radiant heating device is located in the snow-covered area at the tunnel entrance.
[0034] The detection device is installed at the tunnel entrance to detect the state of snow accumulation;
[0035] The radiant heating device, the moving device, and the detection device are connected to the control unit. The control unit controls the working status of the moving device and the radiant heating device based on the feedback data from the detection device to melt the snow and / or ice at the tunnel entrance.
[0036] The radiant heating device is an infrared spotlight 7. The infrared rays emitted by the infrared spotlight are used to melt the snow on the road surface. Multiple infrared spotlights form an infrared spotlight group, which is set at intervals around the tunnel entrance to improve the melting rate of snow and avoid the problem of snow dead spots.
[0037] The mobile device consists of linear modules, electric actuators, and sliding rail structures capable of linear motion. The mobile devices are spaced out circumferentially around the tunnel entrance. Upon receiving a control signal from the control unit, the mobile device drives infrared spotlights to move linearly outwards from the tunnel, emitting infrared rays to melt the accumulated snow.
[0038] Multiple radiant heating devices are preferably spaced apart in the area above the tunnel arch, while controlling the emission angle of infrared light to avoid heating the tunnel walls.
[0039] The infrared spotlight 7 is equipped with an infrared reflector 6, which reflects infrared light so that it faces the snow accumulation.
[0040] The tunnel arch is coated with an infrared reflective coating to prevent infrared rays from heating and damaging the tunnel sidewalls, while also reflecting infrared light to improve its utilization rate.
[0041] In another embodiment, an energy storage device is also included for supplying energy to the mobile device, the radiant heating device, and the control unit. The energy storage device is a new energy storage device, including a solar photovoltaic panel and a battery. The solar photovoltaic panel is connected to the battery, and the battery is connected to the mobile device, the radiant heating device, and the control unit respectively.
[0042] The detection device includes a humidity sensor 2, a temperature sensor 1, and a snowfall monitoring sensor 3. The snowfall monitoring sensor is used to monitor whether it is snowing, and the humidity sensor 2 and the temperature sensor 1 are combined to monitor whether the road surface is icy.
[0043] The control unit is a microcontroller or industrial computer, with preset temperature and humidity thresholds. When the temperature and humidity in the environment both reach the thresholds, it indicates that icing has occurred at the tunnel entrance. The control unit sends a control signal to move the mobile device, which moves the infrared spotlight to the outside of the tunnel and emits infrared light to melt the ice at the entrance.
[0044] Example 1
[0045] See Figure 1-6 A snow removal device for cold-region tunnels based on infrared thermal radiation includes an infrared spotlight 7 at the tunnel entrance and a sliding rail device 8 connected to the infrared spotlight. The control device 5 determines the location of snow accumulation based on data measured by a temperature sensor 1, a humidity sensor 2, and a snowfall monitoring sensor 3. It then controls the sliding rail device 8 to direct the infrared rays emitted by the infrared spotlight 7 directly at the snow-covered, icy area. The infrared rays emitted by the spotlight 7 can quickly heat the area through radiant heat, resulting in rapid and efficient snow removal. This also avoids the corrosive damage to tunnel facilities caused by existing de-icing agents, making it more environmentally friendly and efficient in snow removal.
[0046] like Figure 1 As shown, several humidity sensors 2 and temperature sensors 1 are fixedly installed at the tunnel entrance and on the inner wall. At the same time, several snowfall monitoring sensors 3 are fixedly installed on the outside of the tunnel to monitor whether it is snowing and to determine the location of snow accumulation and ice at the tunnel entrance.
[0047] The infrared reflective coating 4 is applied to a vertical distance of 0.7 meters to 3.5 meters above the cable trench cover. The infrared reflective coating 4 can reflect infrared rays, preventing them from heating and damaging the tunnel sidewalls. At the same time, the infrared rays can be reflected onto the snow-covered and icy road surface by the infrared reflective coating, achieving the effect of snow removal.
[0048] like Figure 2 The control device 5 is fixed on the tunnel sidewall and is electrically connected to the humidity sensor 2, temperature sensor 1, snowfall monitoring sensor 3, infrared spotlight 7, sliding rail device 8 and solar photovoltaic panel 12.
[0049] The supporting force of the slide rail device 8 is provided by the end wall of the tunnel portal; the solar photovoltaic panel 12 is located on the uphill slope of the tunnel portal, and uses photovoltaic cells to directly convert solar energy into electrical energy to provide energy for the infrared spotlight 7 and the slide rail device.
[0050] like Figure 3The slide rail device 8 consists of an inner support 9, an outer support 10, a limiter 11, a limit rod 13, a welding point 14, a steel frame 15, and a drive wheel 16. The inner support 9 is electrically connected to the solar photovoltaic panel 12. After detecting snow accumulation on the road surface, the solar photovoltaic panel 12 provides power to the inner support 9 to make it move. At this time, the infrared spotlight 7 and the infrared reflector 6 welded to the inner support 9 move with the inner support 9.
[0051] Five sets of infrared reflectors 6 and infrared spotlights 7 are provided. Each set of infrared reflectors 6 is at a different angle to the horizontal line, and the angle will not change. This is to ensure that the infrared rays emitted by the infrared spotlights 7 always hit the snow accumulation on the road surface. The steel frame 15 provides support for the slide rail device.
[0052] like Figure 4 The inner bracket 9 has threaded holes pre-drilled at both ends to facilitate the installation of the limiting rod 13 after the inner and outer brackets are fitted together. Each inner bracket 9 has welding points 14 evenly spaced on its inner side, and a set of inner brackets 9 has three welding points 14, which correspond to three sets of infrared spotlights 7. The outer bracket 10 has a limiter 11 in the middle, which is higher than the two side wing plates of the outer bracket 10.
[0053] The inner support 9 and the outer support 10 are characterized in that the inner support 9 can be embedded in the outer support 10 without falling off. After embedding, a limiting rod 13 is installed on the inner support 9. The inner support 9 can move within the outer support 10 and extend outwards. When the inner support 9 extends to a certain extent, the limiting rod 13 on the inner support 9 will be blocked by the limiting device 11 of the outer support 10 to prevent the inner support 9 from extending too far and falling off. An array of drive wheels 16 are laid at the bottom of the two side wing plates of the inner support 9, which are electrically connected to the solar photovoltaic panel 12. The drive wheels 16 drive the inner support 9 to move, thereby satisfying the movement of the infrared spotlight 7.
[0054] Example 2
[0055] A tunnel, wherein the aforementioned snow removal and treatment device for cold-region tunnels based on infrared thermal radiation is installed at the tunnel entrance.
[0056] The snow removal device for tunnels in cold regions is relatively simple to construct and employs simple snow removal methods. It is easy to install and provides timely treatment. The control device 5, which monitors snowfall, responds quickly, rapidly directing the sliding rail device 8 and infrared spotlights 7 to melt snow and ice. Furthermore, after installing this snow removal device, subsequent snow removal costs are low, eliminating the need for manual snow removal after each snowfall, saving significant manpower and resources. Only periodic inspection and maintenance are required. In addition, the entire snow removal device utilizes solar photovoltaic panels 12 for energy, reducing energy costs. Moreover, this snow removal device avoids the corrosive damage to tunnel ancillary facilities caused by traditional de-icing agents, ensuring the tunnel's service life is not affected and making it environmentally friendly.
