Description
Technical Field
[0001] This application relates to the technical field of polar ice and snow airport construction, and in particular to a snow warming device and method for polar ice and snow airport construction. Background Technology
[0002] The polar regions, due to their unique geographical location and harsh weather conditions, are difficult to reach using traditional modes of transportation such as air, sea, and land. However, resource development, scientific research, and tourism activities in the polar regions create an urgent need for an efficient transportation system. The construction of polar ice airports will make transportation in the polar regions more convenient and reliable, providing scientists, researchers, and explorers with easier access to the polar regions for scientific expeditions and research, thereby promoting the development of polar scientific research.
[0003] Currently, the construction of roads for polar ice and snow airports is typically achieved by compacting the snow layer in polar regions. This snow layer usually consists of relatively soft powder snow and denser, harder icy snow. When compacting the snow layer to build the road surface, the soft powder snow on the surface is initially melted, leaving some denser, larger-particle icy snow within the snow layer – this is known as a snow warming process. Then, compacting the icy snow squeezes out the gaps between the ice and snow particles, strengthening their density, cohesion, and stability. This significantly improves the load-bearing capacity of the snow layer, ultimately creating an ice and snow road surface with the rigidity and strength required for the project.
[0004] Regarding the aforementioned technologies, existing technologies typically employ the method of in-situ hot water spraying to warm the snow. However, this method only melts the soft powder snow on the surface, while the powder snow beneath remains. This results in uneven warming of the snow layer, leading to insufficient compaction strength of the snow-covered road surface. Summary of the Invention
[0005] To address the problem of insufficient snow compaction strength caused by uneven warming of the snow layer, this application provides a snow warming device and method for the construction of polar ice and snow airports.
[0006] First aspect
[0007] This application provides a snow warming device for the construction of polar ice and snow airports, which adopts the following technical solution:
[0008] A snow warming device for the construction of polar ice and snow airports includes a vehicle body, a snow suction mechanism, a snow spraying mechanism, a preheating mechanism, and a snow grooming mechanism. The snow suction mechanism includes a first snow storage box, a snow suction machine, and a snow suction pipe. The first snow storage box is fixedly installed on the vehicle body, and the snow suction machine is installed inside the first snow storage box on the side away from the vehicle body. One end of the snow suction pipe extends into the snow, and the other end communicates with the inner cavity of the first snow storage box. The snow spraying mechanism includes a second snow storage box and a snow blower. The second snow storage box is fixedly installed on the vehicle body, and the snow blower is used to blow snow out of the second snow storage box. The preheating mechanism includes a conveying component and a preheating component. The conveying component connects the first snow storage box and the second snow storage box, and the preheating component is fixedly installed on the outside of the conveying component. The snow grooming mechanism includes a snow grooming cylinder, which is rotatably connected to the side of the vehicle body near the second snow storage box.
[0009] By adopting the above technical solution, in the construction of ice and snow airports, when warming the snow layer, the process involves first sucking in powder snow through a snow suction device, then preheating the powder snow through a preheating device and transporting it to a snow spraying device. Next, the snow spraying device sprays the powder snow in batches and layers onto the ground in the construction area. Finally, a snow compaction device compacts the snow layer in layers. Layered snow spraying and layered compaction increase the stability and strength of the compacted road surface. By using a snow suction device to extract the powder snow from the upper layer of the area to be constructed and spraying it in layers, uniform warming of the snow layer in that area can be achieved. This avoids the uneven warming effect caused by simply using hot water spraying, which can result in some areas having too much or too little snow. Therefore, the warming of the snow in the area through the above mechanism is more uniform, improving the efficiency and quality of subsequent compaction work.
[0010] Optionally, the snow suction mechanism includes a speed reducer, a stirring component, and a suction cup. The output end of the snow suction machine is fixedly connected to the speed reducer. The stirring component includes a stirring shaft and a stirring rod. The output end of the speed reducer is fixedly connected to the stirring shaft. The stirring rod is fixedly installed on the peripheral wall of the stirring shaft. The suction cup is connected to the end of the snow suction pipe away from the first snow storage box.
[0011] By adopting the above technical solution, the rotation of the snow vacuum machine's output end can be rationally utilized through the speed reduction component, converting the high-speed rotation of the snow vacuum machine's output end into low-speed rotation. The rotating agitator prevents snow from accumulating in the first snow storage tank and being unable to enter the second snow storage tank, and also initially breaks up some snow clumps that are stuck together, thus facilitating subsequent transportation and preheating melting. The suction cup can increase the snow suction efficiency of the snow suction pipe, further accelerating the snow suction process.
[0012] Optionally, the snow suction pipe is installed inside the stirring shaft and the stirring rod. The snow inlet of the snow suction pipe is located on the side of the stirring shaft near the snow and is connected to the suction cup. The snow outlet of the snow suction pipe is located at the stirring rod.
[0013] By adopting the above technical solution, placing the snow suction pipe inside the mixing shaft and mixing components can significantly improve snow mixing efficiency. Simultaneously, the rotation of the mixing rod causes the snow outlet of the snow suction pipe to continuously move, thus reducing the risk of snow clogging the outlet. The snow suction pipe fully utilizes the rotational motion of the mixing shaft and mixing rod, allowing snow sucked into the first snow storage tank to be sprayed out along the rotating mixing rod, resulting in a more even distribution of snow within the first snow storage tank and reducing the possibility of snow accumulating in large areas, which could affect the operation of the snow suction mechanism.
[0014] Optionally, the conveying assembly includes a conveying pipe, a conveying drive, a conveying shaft, and spiral blades. One end of the conveying pipe is connected to the first snow storage box, and the other end is connected to the second snow storage box. The conveying drive is installed on the outer wall of the second snow storage box, and the output end of the conveying drive is fixedly connected to the conveying shaft. The spiral blades are fixedly installed on the outer peripheral wall of the conveying shaft, and there is a certain gap between the spiral blades and the inner wall of the conveying pipe. The preheating assembly includes a heating wire, which is fixedly wound around the outer peripheral wall of the conveying pipe.
[0015] By adopting the above technical solution, the conveying component can efficiently and directionally transport snow from the first snow storage tank to the second snow storage tank over long distances, while the preheating component can partially melt the snow near the outer wall of the conveying pipe. Through the combined action of the conveying component and the preheating component, the snow inside the first snow storage tank can be converted into a snow-water mixture, consisting of a large amount of snow and a small amount of water, and then the mixture is conveyed to the second snow storage tank.
[0016] Optionally, the preheating component includes a heat insulation sleeve, which is sleeved outside the conveying pipe. The outer peripheral wall of the heating wire abuts against the inner wall of the heat insulation sleeve. The heat insulation sleeve wall is provided with a heat insulation layer and a vacuum layer. The heat insulation layer abuts against the heating wire, and the vacuum layer is located outside the heat insulation layer.
[0017] By adopting the above technical solution, the insulation layer and vacuum layer of the heat insulation sleeve can provide dual protection for heat and reduce heat dissipation. It can not only prevent the low temperature outside the polar region from being conducted into the conveying pipeline, thereby affecting the heating efficiency of the preheating components, but also efficiently preserve the internal heat of the conveying pipeline.
[0018] Optionally, a snow melting mechanism is included, which includes a snow melting component and a water storage tank. Both the snow melting component and the water storage tank are installed inside the second snow storage tank. The water storage tank is installed on the side of the second snow storage tank closer to the vehicle body, and the snow melting component is installed on the side of the water storage tank away from the vehicle body.
[0019] By employing the aforementioned technical solution, the snow melting component deeply melts the snow in the second snow storage tank, ensuring that all the snow entering the component melts and is heated into hot water. Simultaneously, the temperature of the melted snow water and the rising steam further melts the snow in the second snow storage tank, resulting in a higher water content in the final sprayed snow-water mixture. This allows for the formation of more ice crystals in the air, thereby increasing the strength of the polar ice and snow airport road surface.
[0020] Optionally, the snow melting assembly includes snow melting pipes, snow melting components, and a filter screen. Multiple sets of snow melting pipes are provided, with individual snow melting pipes abutting against each other. The snow melting components are sleeved and installed on the outer wall of the snow melting pipes. The snow inlet of the snow melting pipe is connected to the second snow storage tank, the water outlet of the snow melting pipe is connected to the water storage tank, and the filter screen is installed at the snow outlet of the snow melting pipe.
[0021] By employing the above technical solution, the closely arranged snow-melting pipes concentrate the temperature, thereby enhancing the snow-melting effect. The filter screen can, to some extent, prevent snow from falling directly into the water tank from the top of the second snow storage tank without being heated by the snow-melting components. The snow first enters the snow-melting pipes, then is heated by the snow-melting components to melt, and the water within the snow-melting pipes is heated to a high temperature before entering the water tank for storage. The high temperature of the hot water and steam can accelerate the snow-melting efficiency.
[0022] Optionally, the snow grooming mechanism includes multiple snow grooming columns, which are fixedly installed in a ring on the outer peripheral wall of the snow grooming cylinder.
[0023] By adopting the above technical solution, the snow grooming column is fixedly installed in a ring on the outer peripheral wall of the snow grooming cylinder, which improves the snow compaction effect. During the snow grooming process, the snow grooming column increases the contact area between the snow grooming mechanism and the snow layer, reducing the unevenness caused by localized concentrated pressure and the potential damage to the snow layer. In addition, the grooves and protrusions can increase the friction coefficient of the road surface, facilitating vehicle movement.
[0024] Optionally, the snow grooming mechanism includes a snow grooming pipe and a flow guide. The snow grooming pipe is installed inside the snow grooming column. The inlet of the snow grooming pipe is connected to the outlet of the water storage tank, and the outlet of the snow grooming pipe is connected to the inlet of the water storage tank. The flow guide connects the snow grooming pipe and the water storage tank.
[0025] By adopting the above technical solution, the snow grooming pipe can fully utilize the hot water in the storage tank to remelt the snow, thus achieving a better snow warming effect. The hot water in the storage tank is guided into the snow grooming pipe through a flow guide. When the hot water in the snow grooming pipe comes into contact with the road surface, it can stratify and further warm the snow sprayed by the snow spraying mechanism. Simultaneously, the snow grooming column further increases the contact area between the snow grooming cylinder and the snow, allowing more snow to come into contact with the snow layer, resulting in a better melting effect.
[0026] Second aspect
[0027] This application provides a snow warming method for the construction of polar ice and snow airports, which adopts the following technical solution:
[0028] A snow warming method for the construction of polar ice airports, based on a snow warming device for polar ice airport construction, includes the following steps:
[0029] S1. Suctioning powder snow: Start the snow suction machine to create a negative pressure environment inside the first snow storage box, and suck the powder snow on the surface of the snow into the first snow storage box through the snow suction pipe;
[0030] S2, Preheating Powder Snow: Powder snow is conveyed into the snow spraying mechanism through the conveying component, and the preheating component is turned on during the conveying process to initially melt some of the powder snow;
[0031] S3, Layered Snow Spraying: Start the snow blower to blow the powder snow in the second snow storage box into layers and drop it to the ground in stages;
[0032] S4. Snow Compaction: Combined with the layered snow spraying step, each layer of sprayed snow is compacted layer by layer through the snow compactor.
[0033] By adopting the above technical solutions, on the one hand, the surface powder snow can be preheated and melted to achieve a certain degree of warm snow. The steps of layered snow spraying and layered snow compaction can make the warm snow effect better, and can also enhance the strength of the snow surface after the snow layer is compacted, thereby improving the integrity and load-bearing capacity of the snow-covered road surface.
[0034] In summary, this application includes at least one of the following beneficial technical effects:
[0035] 1. By using a snow suction mechanism to extract the powdery snow from the upper layer of the area to be constructed and spray it out in layers, the snow layer in the area can be warmed evenly. The preheating mechanism can preheat and melt the snow, which can make the snow warming effect better and improve the efficiency of subsequent compaction work.
[0036] 2. The snow suction mechanism makes full use of the snow suction machine to make the mixing component rotate. By continuously stirring the snow in the first snow storage box, some snow clumps that are stuck together can be broken up in the initial stage, which makes it easier for the subsequent preheating mechanism to transport and preheat and melt the snow.
[0037] 3. The snow melting mechanism can further melt the snow in the second snow storage tank. At the same time, the combination of the snow melting mechanism and the snow compaction mechanism can improve the snow warming effect, allowing the sprayed snow layer to melt further and making the compacted road surface stronger.

[0042] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0043] This application discloses a snow warming device and method for the construction of polar ice and snow airports.
[0044] First aspect
[0045] This application discloses a snow warming device for the construction of polar ice and snow airports.
[0046] Reference Figure 1A snow warming device for the construction of polar ice and snow airports includes a vehicle body 1, a snow suction mechanism 2, a preheating mechanism 3, a snow spraying mechanism 4, a snow melting mechanism 5, and a snow compaction mechanism 6. The snow suction mechanism 2 and the snow spraying mechanism 4 are both mounted on the vehicle body 1. The preheating mechanism 3 connects the snow suction mechanism 2 and the snow spraying mechanism 4. The snow melting mechanism 5 (see reference...) Figure 3 ( ) works in conjunction with snow pressing mechanism 6 to compact the road surface used for airport construction.
[0047] Reference Figure 2 The snow suction mechanism 2 includes a first snow storage box 21, a snow suction machine 22, a reduction gear 23, a mixing component 24, a snow suction pipe 25, and a suction cup 26. The first snow storage box 21 is fixedly installed on the vehicle body 1. The snow suction machine 22 is installed inside the first snow storage box 21 on the side away from the vehicle body 1. The snow suction machine 22 can create a negative pressure environment inside the first snow storage box 21 by using a fan to draw air for snow suction. The output end of the snow suction machine 22 is fixedly connected to the reduction gear 23. The reduction gear 23 can use the combination of large and small gears to utilize the rotational motion of the snow suction machine 22 and convert high-speed rotation into low-speed rotation. The mixing component 24 includes a mixing shaft 241 and a mixing rod 242. The output end of the reduction gear 23 is fixedly connected to the mixing shaft 241, and the mixing rod 242 is fixedly installed on the peripheral wall of the mixing shaft 241. The snow suction pipe 25 is installed inside the stirring shaft 241 and the stirring rod 242. The snow inlet of the snow suction pipe 25 is located on the side of the stirring shaft 241 near the snow and is connected to the suction cup 26. The snow outlet of the snow suction pipe 25 is located at the stirring rod 242 and is connected to the inner cavity of the first snow storage box 21. The suction cup 26 is connected to the first snow storage box 21 through the snow suction pipe 25. The bottom of the suction cup 26 is provided with protruding teeth 261, and multiple sets of protruding teeth 261 are fixed on the side of the suction cup 26 near the snow.
[0048] Specifically, when the snow suction mechanism 2 is running, the snow suction machine 22 is first activated to create a negative pressure environment inside the first snow storage box 21. Then, the output end of the snow suction machine 22 drives the reducer 23 to rotate, converting the high-speed rotation of the output end of the snow suction machine 22 into a low-speed rotation. Next, the reducer 23 drives the agitator 24 to rotate and agitate. At the same time, snow enters from the suction cup 26 through the snow inlet of the snow suction pipe 25 inside the agitator shaft 241, and then exits from the snow outlet of the snow suction pipe 25 at the agitator rod 242. During the rotation of the agitator 24, firstly, the protruding teeth 261 of the suction cup 26 continuously agitate the snow on the ground, initially breaking it up so that it can more easily enter the first snow storage box 21 through the snow suction pipe 25; secondly, the rotation of the agitator 24 agitates the snow in the first snow storage box 21, preventing snow from accumulating in the first snow storage box 21 and failing to be transferred to the snow spraying mechanism 4; thirdly, the continuous agitation of the snow in the first snow storage box 21 can initially break up some snow clumps that are stuck together, thus facilitating subsequent transportation and preheating melting; finally, due to the continuous rotation and agitation of the agitator rod 242, the position of the snow outlet of the snow suction pipe 25 is also constantly moving, which can also reduce the risk of the snow outlet of the snow suction pipe 25 being blocked by snow to a certain extent. The speed reducer 23 can make reasonable use of the rotation of the output end of the snow suction machine 22, and the suction cup 26 can increase the snow suction efficiency of the snow suction pipe 25.
[0049] Reference Figure 2 and Figure 3 The preheating mechanism 3 includes a conveying component 31 and a preheating component 32. The snow blowing mechanism 4 includes a second snow storage box 41 and a snow blower 42. The conveying component 31 connects the first snow storage box 21 and the second snow storage box 41, and the preheating component 32 is fixedly installed on the outer peripheral wall of the conveying pipe 311 to perform preliminary warming and melting of the snow in the conveying pipe 311.
[0050] Reference Figure 2 and Figure 3The conveying assembly 31 includes a conveying pipe 311, a conveying drive 312, a conveying shaft 313, and a spiral blade 314. One end of the conveying pipe 311 is connected to the first snow storage box 21, and the other end is connected to the second snow storage box 41. In this embodiment, two conveying pipes 311 are provided. The conveying drive 312 is installed on the outer wall of the second snow storage box 41, and the conveying drive 312 can be a rotary motor. The conveying shaft 313 includes a first conveying shaft 3131 and a second conveying shaft 3132. The output end of the conveying drive 312 is fixedly connected to the first conveying shaft 3131. The first conveying shaft 3131 and the second conveying shaft 3132 are connected by a universal joint. The second conveying shaft 3132 is located inside the conveying pipe 311. The spiral blade 314 is fixedly installed on the outer peripheral wall of the second conveying shaft 3132. A certain gap exists between the spiral blade 314 and the inner wall of the conveying pipe 311. A snow-stirring column 315 can be installed on the outer wall of the first conveying shaft 3131 to stir the snow entering the second snow storage box 41. The preheating assembly 32 includes a heating wire 321 (not shown in the figure) and a heat-insulating sleeve 322. The heating wire 321 is fixedly wound around the outer peripheral wall of the conveying pipe 311. The heat-insulating sleeve 322 is fitted over the conveying pipe 311, with the outer peripheral wall of the heating wire 321 abutting against the inner wall of the heat-insulating sleeve 322. An insulation layer 3221 and a vacuum layer 3222 are provided on the wall of the heat-insulating sleeve 322. The insulation layer 3221 abuts against the heating wire 321, and the vacuum layer 3222 is located outside the insulation layer 3221.
[0051] Specifically, the activation of the conveying drive 312 drives the first conveying shaft 3131 and the second conveying shaft 3132 to rotate. The rotation of the second conveying shaft 3132 drives the spiral blades 314 inside the conveying pipe 311 to rotate, thereby conveying snow from the first snow storage box 21 to the second snow storage box 41 through the rotation of the spiral blades 314. During the conveying process, the heating wire 321 is connected to an external power source and continuously heats the snow in the conveying pipe 311. A small portion of the snow in the conveying pipe 311 melts, and what is ultimately conveyed to the second snow storage box 41 is a snow-water mixture consisting of a small amount of water and most of the snow. The preheating mechanism 3 can preheat the snow layer, allowing the sprayed snow-water mixture to better facilitate subsequent snow tamping. The conveying assembly 31, through the conveying pipe 311, the conveying drive 312, the conveying shaft 313, and the spiral blades 314, makes the conveying process more stable. The heat insulation sleeve 322 can efficiently retain the heat in the conveying pipe 311. On the one hand, it can make the heating effect of the preheating component 32 better, and on the other hand, it can reduce the heat loss in the conveying pipe 311, so that the heat generated by the heating wire 321 can be utilized to the greatest extent.
[0052] Reference Figure 2 and Figure 3The second snow storage box 41 of the snow blowing mechanism 4 is fixedly installed on the vehicle body 1. A connecting pipe 7 is provided on the upper part of the first snow storage box 21 and the second snow storage box 41, connecting the first snow storage box 21 and the second snow storage box 41. The snow blower 42 is installed in the connecting pipe 7. The snow blower 42 can be a high-power fan. The suction end of the snow blower 42 is close to the upper part of the first snow storage box 21, and the blowing end of the snow blower 42 is located at the upper part of the second snow storage box 41 so that the snow in the second snow storage box 41 is blown out. A snow spray head is provided at the end of the second snow storage box 41 away from the connecting pipe 7, and the snow is sprayed out through the snow spray head. The connecting pipe 7 connects the first snow storage box 21 and the second snow storage box 41, which can make full use of the suction end of the snow blower 42 and the snow suction machine 22 to form a negative pressure environment quickly and continuously inside the first snow storage box 21 for snow suction, thereby improving the snow suction efficiency of the entire snow suction mechanism 2.
[0053] Furthermore, the combined use of preheating mechanism 3 and snow spraying mechanism 4 effectively sprays a mixture of most of the snow and a small amount of water. During the spraying process, due to the low temperatures in polar regions, the sprayed water quickly freezes into hard ice crystals that fall to the ground. Because ice crystals have high load-bearing capacity and compressive strength, layered snow spraying can increase the stability and strength of the compacted road surface at icy and snowy airports.
[0054] Reference Figure 3 The snow melting mechanism 5 includes a snow melting component 51 and a water storage tank 52. Both the snow melting component 51 and the water storage tank 52 are installed inside a second snow storage tank 41. The water storage tank 52 is installed on the side of the second snow storage tank 41 closest to the vehicle body 1, and the snow melting component 51 is installed on the side of the water storage tank 52 furthest from the vehicle body 1. The snow melting component 51 includes a snow melting pipe 511, a snow melting element 512, and a filter screen 513. Multiple sets of snow melting pipes 511 are provided, with each individual snow melting pipe 511 abutting against each other. In this embodiment, the snow melting pipes 511 fill the middle of the second snow storage tank 41. The snow melting element 512 is sleeved and installed on the outer wall of the snow melting pipe 511. The snow melting element 512, or alternatively, an electric heating wire, heats and melts the snow inside the snow melting pipe, turning it into hot water. To prevent electric shock from contact between the snow melting element 512 and the water, an insulating sleeve can be installed on the outer layer of the snow melting element 512. The snow inlet of the snow melting pipe 511 is connected to the upper part of the second snow storage box 41, and the snow outlet of the snow melting pipe 511 is connected to the water storage tank 52. The filter screen 513 is installed at the snow outlet of the snow melting pipe 511. The first conveying shaft 3131 in the preheating mechanism 3 can be set above the snow melting pipe 511, and the snow stirring column 315 on it continuously stirs the snow so that some of the snow in the second snow storage box 41 can smoothly enter the snow melting pipe 511 for heating and melting.
[0055] Specifically, when the snow melting mechanism 5 is running, the snow melting component 512 first heats the snow melting pipe 511. Snow enters the snow melting pipe 511 from the top of the second snow storage tank 41 and is melted and heated. To prevent snow from falling directly into the water storage tank 52, the filter screen 513 prevents snow from leaving the snow melting pipe 511 without being melted. The snow melting component 51 can melt the snow in the second snow storage tank 41 to a deep depth, ensuring that all the snow entering the snow melting component 51 is heated and melted into hot water, which then enters the water storage tank 52. At the same time, due to the high temperature of the melted snow water and the rising water vapor, the snow in the second snow storage tank 41 can also partially melt, resulting in a higher water content in the sprayed snow-water mixture. After being sprayed, it can form more ice crystals in the air, thereby further improving the strength of the polar ice and snow airport road surface. The snow melting pipes 511 are closely arranged together, which concentrates the temperature and enhances the snow melting effect.
[0056] Reference Figure 1 and 3 The snow grooming mechanism 6 includes a snow grooming cylinder 61, snow grooming columns 62, snow grooming pipes 63, and a flow guide 64. The snow grooming cylinder 61 is rotatably connected to the side of the vehicle body 1 near the second snow storage tank 41. Multiple snow grooming columns 62 are provided and are fixedly installed in a ring on the outer peripheral wall of the snow grooming cylinder 61. The snow grooming pipe 63 is installed inside the snow grooming columns 62. The inlet of the snow grooming pipe 63 is connected to the outlet of the water storage tank 52, and the outlet of the snow grooming pipe 63 is connected to the inlet of the water storage tank 52. The flow guide 64 connects the snow grooming pipe 63 and the water storage tank 52. The flow guide 64 can be a small water pump.
[0057] Specifically, when the snow grooming mechanism 6 is running, the guide vane 64 is activated first, guiding the hot water in the water tank 52 into the snow grooming pipe 63 of the snow grooming column 62. Then, the snow grooming cylinder 61 rotates and presses the snow layer as the vehicle body 1 moves. During the pressing of the snow sprayed by the snow spraying mechanism 4, the hot water in the snow grooming pipe 63 exchanges heat with the snow in the snow layer, causing some of the snow to melt further, achieving a warming effect. The snow grooming column 62 increases the contact area between the snow grooming mechanism 6 and the snow layer. The larger and more evenly distributed contact area between the snow grooming column 62 and the snow layer allows the pressure to be transmitted more evenly throughout the snow layer, reducing the unevenness and potential damage caused by localized concentrated pressure. Furthermore, because the snow grooming column 62 is located on the outer layer of the snow grooming cylinder 61, the pressed road surface has certain grooves and protrusions, rather than a smooth and flat surface, making it easier for the vehicle body 1 to run on the road. Therefore, the snow grooming column 62 can also increase the friction coefficient of the road surface, facilitating vehicle movement.
[0058] In addition, as the water in the water tank 52 continuously circulates when supplying water to the snow compactor 6, the hot water in the tank will continuously increase. Eventually, the water will continuously spread to the upper part of the second snow tank 41. At this time, the snow in the upper part of the second snow tank 41 can melt into snow water more easily, so that the proportion of snow in the snow water mixture in the upper part continuously decreases and the proportion of water continuously increases. Finally, when it is sprayed out, more water forms ice crystals, resulting in a better snow and ice compaction effect on the airport road surface.
[0059] The implementation principle of this embodiment is as follows: In the construction of an ice and snow airport, when warming the snow layer, the snow suction mechanism 2 first sucks the upper layer of powder snow in the area to be constructed into the first snow storage tank 21. Then, the preheating mechanism 3 initially melts the powder snow and transports the snow-water mixture containing a small amount of water to the second snow storage tank 41. Next, the snow spraying mechanism 4 sprays the snow-water mixture in the second snow storage tank 41 onto the ground of the construction area in batches and layers. Each layer of snow-water mixture is compacted separately by the snow compaction mechanism 6. During the compaction process, the snow melting mechanism 5 continuously heats the snow and supplies heat to the snow compaction pipe 63 in the snow compaction mechanism 6, further melting the snow layer. Through the steps of layered snow spraying, layered snow compaction, and multiple snow melting, the warming of the snow can be more uniform, the warming effect is better, and the strength and rigidity of the ice and snow airport pavement are higher.
[0060] Second aspect
[0061] This application discloses a snow warming method for the construction of polar ice and snow airports.
[0062] A snow warming method for the construction of polar ice airports, utilizing the aforementioned snow warming device for polar ice airport construction, includes the following steps:
[0063] S1. Suctioning powder snow: Start the snow suction machine 22 to create a negative pressure environment inside the first snow storage box 21, and suck the powder snow on the surface of the snow into the first snow storage box 21 through the snow suction pipe 25;
[0064] S2, Preheating Powder Snow: Powder snow is conveyed into the snow spraying mechanism 4 through the conveying component 31, and at the same time, the preheating component 32 is turned on during the conveying process to initially melt some of the powder snow;
[0065] S3, Layered Snow Spraying: Start the snow blower 42 to blow the powder snow in the second snow storage box 41 out in stages and layers, and let it fall to the ground;
[0066] S4. Snow Compaction: Combined with the layered snow spraying step, each layer of sprayed snow is compacted layer by layer through the snow groomer 61.
[0067] Through the above steps, the surface powder snow can be preheated and melted to achieve a certain degree of warm snow. The steps of layered snow spraying and layered snow compaction can make the warm snow effect better, and can also enhance the strength of the snow surface after the snow layer is compacted, thereby improving the integrity and load-bearing capacity of the snow-covered road surface.
[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
