Description

Technical Field

[0001] This application relates to the field of roadbed protection technology, and in particular to an intelligent temperature control protection device for frozen soil roadbeds. Background Technology

[0002] Permafrost is a soil medium that is extremely sensitive to temperature. In winter, permafrost, like ice in sub-zero temperatures, expands dramatically in volume as the temperature drops, pushing against the upper roadbed and pavement. In summer, as the temperature rises, the permafrost thaws, shrinking in volume and causing the roadbed to settle. This cyclical change often easily leads to roadbed and pavement collapse, subsidence, deformation, and cracking. Therefore, permafrost roadbed protection devices are needed to reduce the heat absorption and thawing settlement caused by permafrost.

[0003] Most existing permafrost roadbed protection devices include radiation shielding plates and heat pipes. The radiation shielding plates are usually integrated, consisting of horizontal and sloping sections, corresponding to the flat and sloping sections on both sides of the roadbed. The integrated radiation shielding plates are installed on both sides of the permafrost roadbed to protect it and reduce the temperature changes of the permafrost roadbed caused by solar radiation. The heat pipes inserted into the permafrost roadbed conduct heat from the permafrost to the atmosphere through heat conduction and phase change, maintaining the low-temperature stability of the permafrost layer under the roadbed.

[0004] The existing technical solutions mentioned above have the following drawbacks: the inclined part of the integrated radiation shield is only connected to the flat part. In daily operation, the inclined part of the integrated radiation shield is more susceptible to deformation or damage from the external environment than the horizontal part. Replacing the integrated radiation shield is cumbersome and wastes resources. Utility Model Content

[0005] This application provides an intelligent temperature control protection device for frozen soil roadbeds to facilitate the maintenance and replacement of radiation shielding panels and reduce the waste of replacement costs.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: An intelligent temperature control and protection device for frozen soil roadbed includes a base fixed on the roadbed, a heat pipe passing through the base, at least two heat pipes spaced apart, a horizontal radiation shield plate fixed to the base, the heat pipes passing through the horizontal radiation shield plate, a fixing groove on the horizontal radiation shield plate, an inclined radiation shield plate embedded in the fixing groove, the inclined radiation shield plate being inclined to fit the slope of the roadbed, and an anchor rod passing through the inclined radiation shield plate, at least two anchor rods spaced apart, one end of the anchor rod passing through the roadbed, and the other end of the anchor rod being provided with a fixing component.

[0007] By adopting the above technical solution, when the inclined radiation shielding plate is deformed or damaged and needs to be replaced, the fixing components can be released from the anchor rods and the inclined radiation shielding plate. The inclined radiation shielding plate can then be rotated to a vertical position. At this point, the workers can remove the inclined radiation shielding plate from the fixing groove of the horizontal radiation shielding plate. When installing a new inclined radiation shielding plate, the workers place the inclined radiation shielding plate vertically in the fixing groove and then rotate it to fit the roadbed, so that the fixing components fix the inclined radiation shielding plate to the anchor rods. This increases the stability of the inclined radiation shielding plate on the insulation layer of the frozen soil roadbed, facilitates the individual replacement of the inclined radiation shielding plate, and makes maintenance and replacement of the radiation shielding plate easier, reducing the waste of replacement costs.

[0008] Optionally, the fixing component includes a fixed head and a movable head, both of which are sleeved on the anchor rod. The fixed head is located on the side of the inclined radiation shielding plate facing the roadbed, and the movable head is located on the side of the inclined radiation shielding plate away from the roadbed and sleeved on the end of the anchor rod. A connecting sleeve is integrally formed on the movable head, and the connecting sleeve is sleeved on the anchor rod and threaded through and connected to the inclined radiation shielding plate.

[0009] By adopting the above technical solution, the fixing head can increase the contact area between the anchor rod and the inclined radiation shielding plate, and increase the stability of the fixing between the anchor rod and the inclined radiation shielding plate. When replacing the inclined radiation shielding plate, the fixing head can limit the inclined radiation shielding plate, ensuring that the fixing angle and position of the new inclined radiation shielding plate are accurate, which makes it easier for staff to replace the inclined radiation shielding plate, facilitates the maintenance and replacement of the radiation shielding plate, and reduces the waste of replacement costs.

[0010] Optionally, the fixing head is threaded to the anchor rod.

[0011] By adopting the above technical solution, the anchor rod and the fixing head are threaded together, and the tilt angle of the inclined radiation shielding plate that it abuts can be adjusted by rotating the fixing head, which makes it convenient for the staff to adjust the angle of the inclined radiation shielding plate fixed on the insulation layer according to the needs of use.

[0012] Optionally, a buffer strip is fixedly connected inside the fixing groove.

[0013] By adopting the above technical solution, the buffer strip can fit the surface of the inclined radiation shielding plate, ensuring the tightness of the connection between the horizontal radiation shielding plate and the inclined radiation shielding plate.

[0014] Optionally, the bottom surface of the fixing groove is machined to form a concave arc surface.

[0015] By adopting the above technical solution, the bottom of the fixed groove is processed into an arc surface, which makes it easier for workers to rotate the inclined radiation shielding plate and reduces the damage to the inclined radiation shielding plate caused by friction when rotating it.

[0016] Optionally, the groove on one side of the fixing groove is machined to form an inclined surface that fits the inclined radiation shielding plate.

[0017] By adopting the above technical solution, the groove on one side of the fixed groove is processed to form an inclined surface that fits into the inclined radiation shielding plate, which can increase the stability of the connection between the inclined radiation shielding plate and the horizontal radiation shielding plate.

[0018] Optionally, the horizontal radiation shielding plate is integrally formed with a fixing sleeve that is fitted onto the periphery of the heat pipe.

[0019] By adopting the above technical solution, the fixing sleeve can provide horizontal support for the horizontal radiation shielding plate, ensure the stability of the horizontal force on the horizontal radiation shielding plate, reduce the deformation caused by the force at the connection between the horizontal radiation shielding plate and the heat plate, improve the structural strength at the connection between the horizontal radiation shielding plate and the heat rod, and improve the overall structural strength of the heat rod and the base.

[0020] Optionally, a heat insulation layer is fixed inside the movable head.

[0021] By adopting the above technical solutions, the heat insulation layer of the movable head can reduce the heat exchange between the anchor rod and the outside world, maintain the low temperature stability of the frozen soil layer under the roadbed, and reduce the roadbed settlement, deformation or collapse caused by the melting of frozen soil.

[0022] In summary, this application has the following technical effects: 1. By setting up inclined radiation shielding plates, anchor bolts and fixing components, the stability of the inclined radiation shielding plates on the insulation layer of the frozen soil subgrade can be increased, making it easier to replace the inclined radiation shielding plates individually, facilitating the maintenance and replacement of the radiation shielding plates, and reducing the waste of replacement costs. 2. By setting up a buffer strip, the buffer strip can fit against the surface of the inclined radiation shielding plate, ensuring the tightness of the connection between the horizontal radiation shielding plate and the inclined radiation shielding plate; 3. By setting up a heat insulation layer, the heat exchange between the anchor bolt and the outside world can be reduced, the low-temperature stability of the frozen soil layer under the roadbed can be maintained, and the roadbed settlement, deformation or collapse caused by the melting of frozen soil can be reduced.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses an intelligent temperature control and protection device for frozen soil roadbeds, referring to... Figure 1 The frozen soil roadbed includes a roadbed body 1, on which a rubble layer roadbed 11 is laid. The side walls on both sides of the rubble layer roadbed 11 in the length direction are all sloping surfaces, and an insulation layer 12 is provided on both sides of the sloping surfaces of the rubble layer roadbed 11.

[0027] Reference Figure 1 and Figure 2 The protective device includes a base 2 fixed on both sides of the roadbed body 1 along its length. A heat rod 21 is inserted through the base 2. The length of the heat rod 21 is perpendicular to the plane of the base 2. Multiple heat rods 21 are spaced apart on the base 2. One end of the heat rod 21 is inserted into the roadbed body 1, and the other end of the heat rod 21 extends out of the top of the base 2 and is away from the base 2. A horizontal radiation shielding plate 3 is fixed to the base 2 by bolts. The heat rod 21 is inserted through the horizontal radiation shielding plate 3. A fixing sleeve 31 is integrally formed on the horizontal radiation shielding plate 3 and fitted around the periphery of the heat rod 21.

[0028] Reference Figure 2 and Figure 3 A fixing groove 32 is provided on the top of the horizontal radiation shielding plate 3 near the insulation layer 12. An inclined radiation shielding plate 4 is embedded in the fixing groove 32. The inclined radiation shielding plate 4 is inclined and one side of the plate is attached to the insulation layer 12. The bottom surface of the fixing groove 32 is processed to form a concave arc surface. A buffer strip 33 is adhered to the side wall of the fixing groove 32 away from the insulation layer 12. In this embodiment, the buffer strip 33 is made of elastic material and has a triangular cross section. One side of the buffer strip 33 is flush with the top surface of the horizontal radiation shielding plate 3. When the inclined radiation shielding plate 4 is placed at an incline, the plate surface is attached to the plane of the buffer strip 33 facing the bottom of the fixing groove 32. The groove opening of the fixing groove 32 near the insulation layer 12 is processed to form an inclined surface that is attached to the plate surface of the inclined radiation shielding plate 4.

[0029] Reference Figure 2 and Figure 4Anchor rods 5 are installed on the inclined radiation shielding plate 4. The length direction of the anchor rods 5 is perpendicular to the surface of the inclined radiation shielding plate 4, and multiple anchor rods 5 are spaced apart. One end of the anchor rod 5 passes through the insulation layer 12 and inserts into the road base body. The other end of the anchor rod 5 is fitted with a fixing component 6, which includes a fixed head 61 and a movable head 62. Both the fixed head 61 and the movable head 62 are fitted onto the peripheral wall of the anchor rod 5. The fixed head 61 is located on the side of the inclined radiation shielding plate 4 facing the insulation layer 12, and the movable head 62 is located on the side of the inclined radiation shielding plate 4 away from the insulation layer 12. A connecting sleeve 63 is integrally formed on the side of the movable head 62 facing the inclined radiation shielding plate 4, welded to the anchor rod 5 away from the roadbed body 1. The end of the connecting sleeve 63 away from the movable head 62 is inserted into the inclined radiation shielding plate 4. The peripheral wall of the connecting sleeve 63 is machined with external threads, and the inclined radiation shielding plate 4 is machined with internal threads that mate with the external threads of the connecting sleeve 63. The movable head 62 is sleeved on the end of the anchor rod 5 away from the roadbed body 1. A heat insulation layer 64 is bonded inside the movable head 62. The heat insulation layer 64 is sleeved on the end of the anchor rod 5 away from the roadbed body 1.

[0030] When the inclined radiation shielding plate 4 is deformed or damaged and needs to be replaced, the fixing component 6 is released from the anchor rod 5 and the inclined radiation shielding plate 4. The inclined radiation shielding plate 4 is rotated to a vertical position. At this time, the worker can remove the inclined radiation shielding plate 4 from the fixing groove 32 of the horizontal radiation shielding plate 3. When installing the new inclined radiation shielding plate 4, the worker places the inclined radiation shielding plate 4 vertically in the fixing groove 32 and then rotates the inclined radiation shielding plate 4 to fit the insulation layer 12 of the frozen soil subgrade. At this time, the buffer strip 33 made of elastic material can fit the surface of the inclined radiation shielding plate 4, ensuring a tight connection between the horizontal radiation shielding plate 3 and the inclined radiation shielding plate 4. The bottom of the fixing groove 32 is machined into an arc surface, which makes it easier for workers to rotate the inclined radiation shield 4 and reduces the damage to the inclined radiation shield 4 caused by friction when rotating it. The groove opening on one side of the fixing groove 32 is machined into an inclined surface that fits with the inclined radiation shield 4, which can increase the stability of the connection between the inclined radiation shield 4 and the horizontal radiation shield 3. The inclined radiation shield 4 is fixed to the anchor rod 5 by the fixing component 6, which can increase the stability of the inclined radiation shield 4 on the insulation layer 12 of the frozen soil subgrade, facilitate the individual replacement of the inclined radiation shield 4, facilitate the maintenance and replacement of the radiation shield, and reduce the waste of replacement costs.

[0031] When the inclined radiation shielding plate 4 is deformed or damaged and needs to be replaced, the movable head 62 is rotated to disengage it from the threaded connection and remove it from the anchor rod 5. At this time, the anchor rod 5 is away from the inclined radiation shielding plate 4, allowing workers to rotate the inclined radiation shielding plate 4 away from the insulation layer 12, facilitating replacement and reducing the cost of replacement. The fixed head 61 increases the contact area between the anchor rod 5 and the inclined radiation shielding plate 4, increasing the stability of their fixation. When replacing the inclined radiation shielding plate 4, the fixed head 61 can limit its movement, ensuring the accurate fixing angle and position of the new plate. The anchor rod 5 is threadedly connected to the fixed head 61, allowing adjustment of the tilt angle of the inclined radiation shielding plate 4 by rotating the fixed head 61, facilitating adjustment of the angle at which the inclined radiation shielding plate 4 is fixed to the insulation layer 12 according to usage needs.

[0032] When this protective device is used, the base 2 increases the stability of the heat pipe 21 and the horizontal radiation shielding plate 3 on the roadbed body 1. The heat pipe 21, inserted into the roadbed body 1, can actively regulate the temperature of the frozen soil, and conduct heat from the frozen soil to the atmosphere through heat conduction and phase change principles, maintaining the low-temperature stability of the frozen soil layer under the roadbed, and reducing roadbed settlement, deformation, or collapse caused by frozen soil thawing. The fixing sleeve 31 provides horizontal support for the horizontal radiation shielding plate 3, ensuring the horizontal force stability of the horizontal radiation shielding plate 3, reducing deformation caused by force at the connection between the horizontal radiation shielding plate 3 and the heat plate, improving the structural strength at the connection between the horizontal radiation shielding plate 3 and the heat pipe 21, and improving the overall structural strength of the heat pipe 21 and the base 2. The heat insulation layer 64 of the movable head 62 can reduce the heat exchange between the anchor 5 and the outside world, maintain the low-temperature stability of the frozen soil layer under the roadbed, and reduce roadbed settlement, deformation, or collapse caused by frozen soil thawing. The horizontal radiation shielding plate 3 and the inclined radiation shielding plate 4 can reduce the temperature changes of the frozen soil subgrade caused by solar radiation on the main body of the subgrade 1 and the insulation layer 12.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
