Description

Technical Field

[0001] The invention relates to the technical field of frozen soil slope prevention and treatment, and in particular to a frozen soil slope cooling structure. Background Art

[0002] There is usually a thick layer of underground ice in the slopes of permafrost areas. These ice layers remain solid in cold seasons, but may melt in warm seasons. As the global climate warms, the temperature in permafrost areas gradually rises, causing the underground ice layer to begin to melt. Especially in summer, high temperatures accelerate the melting process of the ice layer. When the surface of the slope collapses naturally, the soil structure becomes loose, the thermal conductivity decreases, and the thermal equilibrium state of the underground ice layer is destroyed. As the temperature rises, the underground ice layer begins to melt, forming a mixture of soil, water, and ice, which reduces the friction resistance of the soil. Under the action of gravity, the overlying soil slides along the melting surface of the underground ice layer, forming a thermal melt collapse phenomenon, which will cause damage to surrounding buildings and transportation facilities.

[0003] At present, there is a lack of mature prevention and control technology for permafrost slope disasters. The existing technology generally adopts the method of setting up retaining walls on the slopes. However, in this method, the retaining walls are cast in concrete, and the retaining walls are in a wet and cold environment for a long time. The structure is easily affected, which in turn makes the cooling effect worse. At the same time, the manpower and financial resources spent on building retaining walls are high, and the construction is difficult and costly. Summary of the invention

At the same time, the accumulated water can serve as an insulating layer in summer to reduce the heat transfer of the soil layer of the slope 1. In the cold season, the thermal conductivity of the water increases after freezing, which can accelerate the cooling of the slope 1. The water collection trough 101 is also connected to a drainage pipe 104 and a pump 103. When there is too much water in the water collection trough 101, the water can be discharged from the drainage pipe 104 through the pump 103 to adjust the water capacity in the water collection trough 101 to prevent excessive water from affecting the overall stability of the slope 1.

[0032] like Figure 2-4 As shown, the sunshade assembly includes a driving structure, a side plate structure and a sunshade 8 arranged at the upper end of the side plate structure, the driving structure is arranged on the slope 1, the side plate structure and the driving structure are connected, the driving structure drives the side plate structure to move, the driving structure includes at least two support grooves 2 and a plurality of groups of driving parts, and the two support grooves 2 are distributed in parallel on the slope 1, one end of the support groove 2 is provided with a pipe pile 21, the lower end of the pipe pile 21 is in the shape of a spiral drill bit, the pipe pile 21 is inserted into the slope 1, and the entire support groove 2 can be fixed on the slope 1, the support groove 2 is hollow inside, and one end is penetrated by the setting There is a connecting groove 22, and the driving member is slidably arranged in the supporting groove 2. The driving member is a rotating wheel group, which includes two rotating wheels 3 and a connecting shaft 31 arranged between the two rotating wheels 3. The rotating wheels 3 rotate at both ends of the connecting shaft 31. The rotating wheel group is clamped in the supporting groove 2. A motor 4 is connected to one of the rotating wheels 3. An auxiliary groove 41 is arranged at one end of the supporting groove 2. The motor 4 is connected to the auxiliary groove 41. When the motor 4 drives one of the rotating wheels 3 to rotate, the motor 4 drives the entire driving member to move along the direction of the supporting groove 2, and the motor 4 slides in the auxiliary groove 41.

[0033] like Figure 2-9 The side panel structure includes a plurality of connecting rods 5 and a plurality of groups of panels. One end of the connecting rod 5 passes through the supporting groove 2 and is connected to the connecting shaft 31, and the connecting rod 5 extends out from the connecting groove 22. Each group of panels is composed of a plurality of side panels 61 that can be folded together. The two ends of each group of panels are respectively connected to the connecting rod 5. When the motor 4 is working, the motor 4 can make the connecting rod 5 move along the direction of the connecting groove 22, thereby folding the adjacent side panels 61.

[0034] like Figure 5-9As shown, a buckle ring 63 and a clamping ring 65 connected to the connecting rod 5 are provided on the plate, and a rotating shaft 62 is provided between adjacent side plates 61, and the adjacent side plates 61 rotate around the rotating shaft 62 as an axis. The plate includes plate IA and plate IB. Both ends of plate IA are provided with buckles 63. The buckles 63 are directly mounted on the connecting rod 5 to complete the connection between the plate and the connecting rod 5. One of the plate IA is connected to the frontmost connecting rod 5, and the connecting rod 5 at the rearmost end is also connected to the plate IA. One end of plate IB is provided with a buckle 63 and the other end is provided with a snap ring 65. There is an opening on the snap ring 65. The snap ring 65 can be snapped onto the connecting rod 5 by prying open the opening, and the snap ring 65 will not detach from the connecting rod 5. During subsequent dismantling, the snap ring 65 can be pried open by external force to separate plate IA and connecting rod 5, and plate IA rotates along the connecting rod 5. When plate IA and plate IB are connected to the same connecting rod 5, the buckle 63 and the snap ring 65 are staggered, and the buckle 63 and the snap ring 65 can rotate on the connecting rod 5, so that the connecting rod 5 can realize the folding of the plate during the movement.

[0035] like Figure 5 , 6 As shown, hinges for limiting the rotation direction of side plate 61 are provided on side plate 61 and rotating shaft 62, and a groove 64 of the same shape as the hinge is provided on side plate 61. The hinge includes two connecting plates 71 and a support column 7 arranged between the two connecting plates 71. The connecting plate 71 rotates around the support column 7 as the center of a circle, and a torsion spring 72 is arranged inside the support column 7. Both sides of the torsion spring 72 are connected to the connecting plate 71, so that the connecting plate 71 can only rotate in one direction. The connecting plate 71 is directly placed in the groove 64, and the support column 7 is supported on the rotating shaft 62, and the support column 7 and the rotating shaft 62 can be fixedly connected by bolts 73. When the side plate 61 is opened, the torsion spring 72 is compressed. At the same time, after the hinge is set, when the side plate 61 rotates relatively, the hinge makes the side plate 61 rotate in only one direction, preventing the side plate 61 from interfering during the contraction process, thereby affecting the quality of the side plate 61. The torsion spring 72 can also provide thrust when the side plate 61 is folded, reduce the power of the motor 4, and increase the service life of the entire structure.

[0036] like Figure 1 , 2 As shown in , 8 and 9, since the cooling structure is set in the permafrost area and the power supply is difficult, the sun visor 8 adopts a solar panel to convert solar energy into electrical energy for storage and supply power to electrical equipment (such as the motor 4 and the pump 103). Connecting blocks 81 are set at both ends of the sun visor 8. The connecting blocks 81 are detachably set on the connecting rod 5. The connecting blocks 81 and the connecting rod 5 are connected by bolts. When the sun visor 8 is damaged, the sun visor 8 can be removed and replaced by unscrewing the bolts. The same is true during installation, which increases the disassembly and assembly efficiency of the sun visor 8. When the connecting rod 5 slides, the sun visor 8 moves accordingly to achieve expansion and contraction.

[0037] like Figure 1 , 2 As shown in Figures 8 and 9, a partition 9 is provided on the connecting rod 5. The partition 9 is provided on the connecting rod 5 of two adjacent supporting grooves 642. The partition 9 and the connecting rod 5 are connected by buckling. Buckling parts 91 are provided on both sides of the partition 9. One end of the buckling part 91 is arc-shaped and can be elastically deformed. The arc-shaped end is buckled on the connecting rod 5. The upper end of the partition 9 is connected to the sun visor 8. The partition 9 closes the ventilation area. There is a ventilation slot C between the partition 9 and the slope 1. In the cold season, the side panel 61 is folded, and the sun visor 8 is folded synchronously. The cold energy of the air is used to cool the slope 1. In the warm season, the side panel 61 and the sun visor 8 are opened to block the sunlight. At the same time, air is blown into the ventilation slot C. The low thermal conductivity of the air is used to form a closed insulation layer to isolate the upper heat, thereby achieving a cooling effect on the slope 1 at different temperatures.

For those skilled in the art, the present invention may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
