Description

Technical Field

[0001] This invention relates to the field of high-speed railway tunnel technology, and more specifically, to a fixing device. Background Technology

[0002] Currently, in order to ensure the continuity and safety of communication signals during high-speed rail operation, a large number of communication boxes need to be suspended and fixed to the walls inside the tunnel using bolts or back plates.

[0003] However, when a high-speed train travels at high speed in a tunnel, the air in front of the train is compressed to create a strong positive pressure airflow, while the rear of the train generates a strong negative pressure suction effect. This physical phenomenon is known as the "piston wind effect" in tunnels. This extreme and frequently alternating strong wind pressure not only results in extremely high wind speeds but is also accompanied by violent mechanical vibrations as the train passes. When a high-speed train passes by at high speed, the strong piston wind directly impacts the communication box, causing it to bear a huge wind resistance load. Long-term violent vibrations can easily cause the cabinet door of the communication box to be blown open or the bolts fixing the communication box to the wall to loosen, ultimately leading to the exposure and damage of the precision electronic communication equipment inside the communication box or the communication box falling off the wall, reducing the operational reliability of the communication box. Summary of the Invention

[0004] The main objective of this invention is to provide a fixing device to solve the problem of low operational reliability of communication boxes in high-speed railway tunnels due to piston wind in the prior art.

[0005] To achieve the above objectives, the present invention provides a fixing device, comprising: a housing disposed on a working base surface, the housing having a receiving cavity for accommodating electrical components; at least two fixing components disposed on opposite sides of the housing along a first preset direction, the at least two fixing components surrounding each other to form a fixing space, the size of the fixing space being adjustable for fixing the housing; and a protective component, both ends of the protective component being connected to the at least two fixing components, at least a portion of the protective component being disposed opposite to or within the fixing space, the protective component being used to abut against the end of the housing away from the working base surface; wherein, along the end of the protective component near the fixing space to the end away from the fixing space, the width of the fixing component gradually decreases, so that the side of the fixing component away from the fixing space forms a guide surface.

[0006] Furthermore, the fixing component includes: a fixing structure having an installation cavity; a first locking member passing through the inner wall of the installation cavity to lock the fixing structure onto the working base surface; and a flow guiding structure disposed on the fixing structure to block the installation cavity; wherein, along the end of the protective component near the fixing space to the end away from the fixing space, the width of the fixing structure gradually decreases so that the end face of the flow guiding structure away from the fixing structure forms a flow guiding surface.

[0007] Furthermore, the protective component includes: a protective structure, the two ends of which are respectively connected to at least two fixed components; a buffer structure disposed on the protective structure and abutting against the housing; wherein at least a portion of the buffer structure is made of flexible material.

[0008] Furthermore, the fixing component has a first locking groove extending along a second preset direction, and the protective structure has a second locking groove extending along the first preset direction. The second preset direction and the first preset direction are set at an angle. The protective component also includes a second locking member that passes through the second locking groove and is threadedly engaged with the first locking groove. The second locking member abuts against at least a portion of the outer surface of the protective structure to fix the protective structure.

[0009] Furthermore, the fixing device also includes: at least two heat dissipation components, which are respectively disposed at opposite ends of the housing along a second preset direction, with the second preset direction and the first preset direction forming an angle; wherein, the heat dissipation components have heat dissipation channels, which are connected to the housing cavity of the housing, so that the heat in the housing cavity can be discharged through the heat dissipation channels.

[0010] Furthermore, the heat dissipation component includes: blades, which are rotatably disposed within the heat dissipation channel, and the rotation direction of the blades is adjustable; wherein, there are multiple blades, and the multiple blades are spaced apart along a first preset direction.

[0011] Furthermore, the heat dissipation assembly also includes a drive rod, which is connected to multiple blades to drive the other blades to rotate as one blade rotates.

[0012] Furthermore, the blade has a connecting recess, and the heat dissipation assembly also includes a connecting post, which passes through the transmission rod, with its two ends rotatably connected to the two inner walls opposite to the connecting recess.

[0013] Furthermore, the heat dissipation channel has through holes on its two opposite side walls. The heat dissipation assembly also includes: an anti-rotation structure connected to multiple blades, with both ends of the anti-rotation structure passing through the through holes and slidably disposed along the extension direction of the through holes; at least two fasteners, which are locked to both ends of the anti-rotation structure and are located outside the heat dissipation channel; wherein the outer edge of the fastener protrudes from the outer edge of the anti-rotation structure and is used to abut against the outer peripheral surface of the heat dissipation channel to fix the anti-rotation structure.

[0014] Furthermore, the heat dissipation assembly also includes: a main body structure, comprising at least two first main body parts and at least two second main body parts, the at least two first main body parts being spaced apart on the housing along a first preset direction, the two ends of the second main body parts being respectively connected to the at least two first main body parts, and the at least two first main body parts and the at least two second main body parts surrounding each other to form a heat dissipation channel; a rotating column, one end of the rotating column being connected to the blades, and the other end of the rotating column being rotatably connected to the second main body parts.

[0015] Applying the technical solution of this invention, the housing of the fixing device is set on the working base surface. The housing has a receiving cavity for accommodating electrical components. At least two fixing components are respectively arranged on opposite sides of the housing along a first preset direction, forming a fixing space between the at least two fixing components. The size of the fixing space is adjustable for fixing the housing. Two ends of a protective component are respectively connected to the at least two fixing components. At least a portion of the protective component is arranged opposite to or within the fixing space, and the protective component is used to abut against the end of the housing away from the working base surface. The width of the fixing component gradually decreases from the end of the protective component near the fixing space to the end away from the fixing space, so that the side of the fixing component away from the fixing space forms a guide surface. Thus, the operator first places the electrical components used for communication into the receiving cavity of the housing, and then fixes the housing to the wall inside the high-speed rail tunnel. Next, the two fixing components are placed on opposite sides of the housing along the first preset direction, and the positions of the two fixing components are adjusted so that at least a portion of the housing is located within the fixing space formed by the two components, until the two fixing components are tightly abutted against the sides of the housing, and then the fixing components are locked in place. Therefore, after the enclosure is fixed to the wall, it is further secured laterally from both sides. Then, the workers connect the two ends of the protective component to the two fixing components, so that the protective structure abuts against the end of the enclosure away from the wall, forming a physical protective beam that reliably confines the enclosure to the wall. This prevents the enclosure from falling off the wall and reduces the probability of the enclosure door being accidentally opened by strong winds. Simultaneously, because the fixing component is angled away from the enclosure, it forms a guide surface. When piston-like winds occur in the tunnel and directly impact the enclosure, this guide surface buffers and guides the airflow. The airflow guided by the guide surface blows towards the protective structure, which further buffers the direct impact of the airflow on the enclosure, thus significantly reducing the damage of wind pressure loads to the enclosure and its internal electrical components. This ensures the operational reliability of the electrical components inside the enclosure, thereby solving the problem of low operational reliability of communication enclosures in high-speed rail tunnels due to piston-like winds in existing technologies.

[0030] To address the issue of low operational reliability of communication boxes in high-speed railway tunnels due to piston wind in existing technologies, this application provides a fixing device.

[0031] like Figures 1 to 4 As shown, the fixing device includes a housing 2, at least two fixing components 10, and a protective component 20. The housing 2 is disposed on a working base surface 1 and has a receiving cavity for accommodating electrical components. The at least two fixing components 10 are respectively disposed on opposite sides of the housing 2 along a first preset direction, and a fixing space 14 is formed between the at least two fixing components 10. The fixing space 14 is adjustable in size for fixing the housing 2. Both ends of the protective component 20 are respectively connected to the at least two fixing components 10. At least a portion of the protective component 20 is disposed opposite to or within the fixing space 14, and the protective component 20 is used to abut against the end of the housing 2 away from the working base surface 1. The width of the fixing component 10 gradually decreases from the end of the protective component 20 near the fixing space 14 to the end away from the fixing space 14, so that the side of the fixing component 10 away from the fixing space 14 forms a guide surface.

[0032] Using the technical solution of this embodiment, the housing 2 of the fixing device is set on the working base surface 1. The housing 2 has a receiving cavity for accommodating electrical components. At least two fixing components 10 are respectively arranged on opposite sides of the housing 2 along a first preset direction, and a fixing space 14 is formed between the at least two fixing components 10. The size of the fixing space 14 is adjustable for fixing the housing 2. The two ends of the protective component 20 are respectively connected to the at least two fixing components 10. At least a portion of the protective component 20 is arranged opposite to or within the fixing space 14, and the protective component 20 is used to abut against the end of the housing 2 away from the working base surface 1. The width of the fixing component 10 gradually decreases from the end of the protective component 20 near the fixing space 14 to the end away from the fixing space 14, so that the side of the fixing component 10 away from the fixing space 14 forms a guide surface. In this way, the operator first places the electrical components used for communication in the receiving cavity of the housing 2, and then fixes the housing 2 to the wall inside the high-speed rail tunnel. Next, the two fixing components 10 are placed on opposite sides of the housing 2 along the first preset direction, and their positions are adjusted so that at least part of the housing 2 is located within the fixed space 14 enclosed by the two components. The fixing components 10 are then locked in place until they are firmly abutting against the sides of the housing 2. Thus, the housing 2 is further secured laterally from both sides, building upon its fixation to the wall. Afterwards, the workers connect the two ends of the protective component 20 to the two fixing components 10, so that the protective structure 21 abuts against the end of the housing 2 furthest from the wall, forming a physical protective beam that reliably confines the housing 2 to the wall. This prevents the housing 2 from falling off the wall and reduces the probability of the cabinet door being accidentally opened by strong winds. Simultaneously, because the fixing component 10 is tilted on the side furthest from the housing 2, it forms a guide surface. When piston-like winds are generated in the tunnel and directly impact the housing 2, this guide surface can buffer and guide the airflow. After being guided by the guide surface, the airflow will blow towards the protective structure 21. The protective structure 21 can further buffer the direct impact of the airflow on the box 2, thereby significantly reducing the damage of wind pressure load to the box 2 and its internal electrical components, ensuring the operational reliability of the electrical components inside the box 2, and thus solving the problem of low operational reliability of communication boxes in high-speed railway tunnels due to piston wind in the existing technology.

[0033] In this embodiment, the working base surface 1 is the wall inside the high-speed railway tunnel.

[0034] Specifically, the box 2 is fixed to the wall by expansion bolts.

[0035] In this embodiment, the box 2 is arranged in the shape of a cuboid, the height direction of the box 2 is perpendicular to the wall, and the first preset direction is consistent with the width direction of the box 2.

[0036] In this embodiment, there are four fixing components 10. The four fixing components 10 are divided into two groups. The two groups of fixing components 10 are spaced apart along the length direction of the box body 2. The two fixing components 10 in each group are spaced apart along the width direction of the box body 2 on both sides of the box body 2.

[0037] In this embodiment, there are two protective components 20, which are spaced apart along the length of the housing 2 to enhance the protection of the housing 2.

[0038] like Figure 2 As shown, the fixing assembly 10 includes a fixing structure 11, a first locking member 12, and a flow guiding structure 13. The fixing structure 11 has a mounting cavity 111. The first locking member 12 passes through the inner wall of the mounting cavity 111 to lock the fixing structure 11 onto the working base surface 1. The flow guiding structure 13 is disposed on the fixing structure 11 to seal the mounting cavity 111. The width of the fixing structure 11 gradually decreases along the protective assembly 20 from the end near the fixing space 14 to the end away from the fixing space 14, so that the end face of the flow guiding structure 13 away from the fixing structure 11 forms a flow guiding surface. Thus, the worker passes the first locking member 12 through the inner wall of the mounting cavity 111 to lock the fixing structure 11 onto the wall, achieving the connection between the fixing assembly 10 and the wall. Then, the flow guiding structure 13 is placed on the fixing structure 11 to seal the mounting cavity 111, isolating the first locking member 12 from the external environment, preventing damage to the first locking member 12, and ensuring the stability of the fixing structure 11. Meanwhile, the mounting cavity 111 of the fixing structure 11 allows for lightweight design, facilitating assembly and disassembly by workers. Furthermore, as the width of the fixing structure 11 gradually decreases, the flow guiding structure 13 is tilted when connecting to the fixing structure 11 and sealing the mounting cavity 111. This creates a flow guiding surface on the end face of the flow guiding structure 13 away from the mounting cavity 111, simplifying and making its formation easier.

[0039] In this embodiment, the flow guiding structure 13 is plate-shaped.

[0040] In this embodiment, the first locking element 12 is a bolt.

[0041] like Figures 1 to 3As shown, the protective component 20 includes a protective structure 21 and a buffer structure 22. Both ends of the protective structure 21 are connected to at least two fixed components 10. The buffer structure 22 is disposed on the protective structure 21 and abuts against the housing 2; wherein, at least a portion of the buffer structure 22 is made of flexible material. Thus, the protective component 20 is connected to the two fixed components 10 through the protective structure 21 and achieves abutment against the housing 2 through the buffer structure 22. When the high-speed train passes through the tunnel and experiences piston-like vibrations, the buffer structure 22, made of flexible material, not only absorbs the impact energy and mitigates the rigid collision between the housing 2 and the protective structure 21, protecting the structural integrity of the housing 2, but also provides elastic preload, ensuring that the housing 2 remains stably fitted to the wall within the fixed space 14, further preventing loosening and detachment of the housing 2 and extending the operational reliability of the electrical components.

[0042] In this embodiment, the flexible material includes one or more of the following: silicone, rubber, and plastic.

[0043] Optionally, the buffer structure 22 may also be equipped with a spring or other structure capable of buffering.

[0044] In this embodiment, the protective structure 21 is connected to the end face of the fixed structure 11 away from the wall.

[0045] like Figures 1 to 3 As shown, the fixing component 10 has a first locking groove 112 extending along a second preset direction. The protective structure 21 has a second locking groove 211 extending along a first preset direction, with the second preset direction forming an angle with the first preset direction. The protective component 20 also includes a second locking member 23, which passes through the second locking groove 211 and is threadedly engaged with the first locking groove 112. The second locking member 23 abuts against at least a portion of the outer surface of the protective structure 21 to fix the protective structure 21. Thus, the operator threadedly connects the second locking member 23 through the second locking groove 211 to the first locking groove 112, thereby locking the protective structure 21 onto the fixing component 10. Meanwhile, since the first locking groove 112 of the fixing component 10 extends along the second preset direction and the second locking groove 211 of the protective structure 21 extends along the first preset direction, and the two are set at an angle, this cross groove design allows the protective structure 21 to be finely adjusted in position in two degrees of freedom, thereby adapting to the dimensional tolerances or unevenness of the wall during the installation of the housing 2. This allows the protective structure 21 to be stably installed on the fixing component 10 while also being tightly abutting against the housing 2. At the same time, the way the second locking member 23 abuts against the outer surface of the protective structure 21 can provide an anti-loosening torque, ensuring that the connection of the second locking member 23 does not loosen under long-term vibration environment, improving the locking reliability of the second locking member 23, and also improving the fixing reliability of the fixing device.

[0046] In this embodiment, the fixing structure 11 has a first locking groove 112.

[0047] In this embodiment, the second locking element 23 is a bolt.

[0048] In this embodiment, the second preset direction is consistent with the length direction of the box 2.

[0049] like Figure 1 and Figure 2 As shown, the fixing device also includes at least two heat dissipation components 30, which are respectively arranged at opposite ends of the housing 2 along a second preset direction, forming an angle with the first preset direction. Each heat dissipation component 30 has a heat dissipation channel 363, which communicates with the receiving cavity of the housing 2, allowing heat to be discharged from the receiving cavity. Thus, the heat generated by the electrical components within the receiving cavity during operation can be dissipated through the heat dissipation channels 363 at both ends. Since the heat dissipation components 30 are installed along the second preset direction, forming an angle with the fixing component 10, the strong winds inside the tunnel are primarily borne by the fixing component 10, while the heat dissipation components 30 are not directly impacted by the wind. This prevents strong winds from directly entering the receiving cavity while simultaneously dissipating heat from the housing 2, ensuring the stability of the housing 2's installation and the operational safety of the electrical components. This achieves a harmonious balance between windproof fixing and reliable heat dissipation in the fixing device.

[0050] In this embodiment, two heat dissipation components 30 are provided, and the two heat dissipation components 30 are respectively provided at the top and bottom ends of the box body 2 along its length.

[0051] like Figure 1 , Figure 2 and Figure 4 As shown, the heat dissipation component 30 includes blades 31, which are rotatably disposed within the heat dissipation channel 363. The rotation direction of the blades 31 is adjustable. Multiple blades 31 are spaced apart along a first preset direction. This allows operators to adjust the deflection angle of the blades 31 according to the actual working conditions of the enclosure 2, flexibly controlling the ventilation area of ​​the heat dissipation channel 363 under different conditions. When efficient heat dissipation is required for the enclosure 2, the ventilation area of ​​the heat dissipation channel 363 is increased to enhance air convection. When there is strong wind in the tunnel, the ventilation area of ​​the heat dissipation channel 363 can be reduced, using the inclined channel formed by the blades 31 to block the entry of residual strong winds after being guided and buffered by the fixing component 10. This balances the heat dissipation needs of the enclosure 2 with the protection needs under extreme wind pressure, significantly improving the environmental adaptability and operational flexibility of the fixing device.

[0052] like Figure 4As shown, the heat dissipation assembly 30 also includes a transmission rod 32, which is connected to multiple blades 31 so that the rotation of one blade 31 drives the rotation of the other blades 31. Thus, when an operator rotates any blade 31, the transmission rod 32 drives all the remaining blades 31 to rotate synchronously. This makes adjusting the angle of the multiple blades 31 simpler and faster, eliminating the need for individual adjustments and ensuring consistent opening of all blades 31. This avoids uneven local ventilation or strong winds due to different angles, ensuring the heat dissipation reliability of the heat dissipation assembly 30.

[0053] In this embodiment, the transmission rod 32 is rectangular.

[0054] like Figure 4 As shown, the blade 31 has a connecting recess, and the heat dissipation assembly 30 also includes a connecting post 33. The connecting post 33 passes through the transmission rod 32, and its two ends are rotatably connected to the two inner walls of the connecting recess. Thus, the connecting post 33, passing through the transmission rod 32 and rotatably connected to the inner walls of the connecting recess, achieves a hinge connection between the transmission rod 32 and the blade 31. The connecting post 33 acts as a pivot, ensuring flexible and unhindered relative rotation between the transmission rod 32 and the blade 31. The connecting post 33 provides necessary support and frictional resistance during the adjustment of the transmission rod 32's movement, ensuring smooth operation of the transmission rod 32 during deflection and preventing it from wobbling under its own weight. Simultaneously, the connecting recess provides a stable installation space for the connection between the transmission rod 32 and the connecting post 33, preventing axial movement of the connecting post 33. This connection method is simple, reliable, easy to assemble, and can withstand long-term vibration without loosening, ensuring the stability and service life of the linkage transmission.

[0055] In this way, the transmission rod 32, the connecting column 33, and the multiple blades 31 form a structure similar to a louver.

[0056] like Figure 4As shown, the heat dissipation channel 363 has through holes on its two opposite sidewalls. The heat dissipation assembly 30 also includes an anti-rotation structure 34 and at least two fasteners 35. The anti-rotation structure 34 is connected to all the blades 31. Both ends of the anti-rotation structure 34 pass through the through holes and are slidably arranged along the extension direction of the through holes. At least two fasteners 35 are locked to both ends of the anti-rotation structure 34 and are located outside the heat dissipation channel 363. The outer edge of the fastener 35 protrudes from the outer edge of the anti-rotation structure 34 and is used to abut against the outer peripheral surface of the heat dissipation channel 363 to fix the anti-rotation structure 34. In this way, the anti-rotation structure 34 is connected to all the blades 31, and its two ends pass through the through holes in the sidewalls of the heat dissipation channel 363 and are slidably arranged, so that the anti-rotation structure 34 can slide with the transmission rod 32 and the multiple blades 31, ensuring the smoothness of the angle adjustment of the multiple blades 31. After the angles of multiple blades 31 are adjusted appropriately, the workers tighten the fasteners 35 and the two ends of the anti-rotation structure 34, so that the locking parts abut against the outer peripheral surface of the heat dissipation channel 363 to ensure the fixation of the anti-rotation structure 34. This allows multiple blades 31 to follow the fixed angle of the anti-rotation structure 34, thereby locking the rotation angle of all blades 31. The abutment between the fasteners 35 and the outer peripheral surface of the channel provides a reliable anti-loosening torque, preventing the blades 31 from being passively deflected under the impact of strong winds, and ensuring the constant long-term ventilation angle of the housing 2.

[0057] In this embodiment, the anti-rotation structure 34 is in the shape of a cylindrical rod, and both ends of the anti-rotation structure 34 have threaded sections. The fastener 35 is a nut, and the anti-rotation structure 34 and the fastener 35 are threadedly engaged.

[0058] In this embodiment, two transmission rods 32 are provided, and the two transmission rods 32 are located on both sides of the anti-rotation structure 34 along the length direction of the housing 2, so as to enhance the transmission balance.

[0059] like Figure 4As shown, the heat dissipation assembly 30 also includes a main structure 36 and a rotating column 37. The main structure 36 includes at least two first main body parts 361 and at least two second main body parts 362. The at least two first main body parts 361 are spaced apart on the housing 2 along a first preset direction. The two ends of the second main body parts 362 are respectively connected to the at least two first main body parts 361. The at least two first main body parts 361 and the at least two second main body parts 362 surround each other to form a heat dissipation channel 363. One end of the rotating column 37 is connected to the blade 31, and the other end of the rotating column 37 is rotatably connected to the second main body part 362. In this way, the main structure 36 forms a stable heat dissipation channel 363 frame through the first main body parts 361 and the second main body parts 362, ensuring the integration of the main structure 36 with the housing 2, and also ensuring the overall rigidity of the main structure 36 and the housing 2. This makes the heat dissipation assembly 30 more modular and easier to manufacture, assemble, and maintain. Meanwhile, the rotating column 37 serves as the rotation axis of the blade 31, and its rotational connection with the second main body 362 ensures the smooth opening and closing of the blade 31. Furthermore, the rotating column 37 is located inside the channel, so it does not affect the path of the external airflow, thereby improving the stability and accuracy of the blade 31's rotation.

[0060] In this embodiment, the first main body 361 has a through hole.

[0061] In this embodiment, there are two first main body parts 361 and two second main body parts 362, and the two first main body parts 361 and the two second main body parts 362 surround each other to form a rectangular frame.

[0062] Specifically, the staff first place the electrical components used for communication inside the receiving cavity of the housing 2, and then fix the housing 2 to the wall inside the high-speed rail tunnel. Next, two fixing structures 11 are placed on opposite sides of the housing 2 along a first preset direction, and the positions of the two fixing structures 11 are adjusted so that at least part of the housing 2 is located within the fixed space 14 enclosed by the two structures, until the two fixing structures 11 are tightly abutting against the sides of the housing 2. Then, the first locking member 12 is passed through the inner wall of the mounting cavity 111 of the fixing structure 11 and locked to the wall. After that, the flow guiding structure 13 is installed on the fixing structure 11 and the mounting cavity 111 is sealed, so that the end face of the flow guiding structure 13 forms an inclined flow guiding surface. Thus, after the housing 2 is fixed to the wall, the housing 2 is further tightened laterally from both sides. Subsequently, the workers threaded the second locking member 23 through the second locking groove 211 of the protective structure 21 and into the first locking groove 112 of the fixed structure 11, connecting both ends of the protective structure 21 to the two fixed structures 11 respectively. A buffer structure 22 is provided at the end of the protective structure 21 near the housing 2, abutting against the housing 2, allowing the protective component 20 to reliably be confined to the wall across the width of the housing 2. When piston-like winds are generated inside the tunnel and directly impact the housing 2, the guide surface buffers and guides the airflow. The airflow guided by the guide surface blows towards the protective structure 21, which further buffers the direct impact of the airflow on the housing 2, thereby significantly reducing the damage of wind pressure loads to the housing 2 and its internal electrical components, ensuring the operational reliability of the electrical components inside the housing 2. Meanwhile, since the electrical components inside the enclosure 2 generate a lot of heat during operation, the staff can turn one of the blades 31 of the two heat dissipation components 30 located at both ends of the enclosure 2 along its length. The transmission rod 32 will drive the remaining blades 31 to rotate, so that the blades 31 rotate to a suitable angle. At this time, the anti-rotation structure 34 slides with the blades 31 in the through hole. Then, the staff will thread the fasteners 35 onto the two ends of the anti-rotation structure 34 and fix the anti-rotation structure 34, thereby fixing the rotation angle of the blades 31. This allows the heat dissipation channel 363 to reasonably dissipate the heat inside the enclosure 2 and facilitates the placement of the heat dissipation components 30 and the deflection angle of the blades 31. This prevents strong winds from entering the enclosure 2 and ensures the installation stability of the enclosure 2 and the operational reliability of the electrical components.

[0063] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0064] The mounting housing is set on the working base surface and has a receiving cavity for accommodating electrical components. At least two mounting components are respectively positioned on opposite sides of the housing along a first preset direction, forming a fixed space between them. The size of the fixed space is adjustable for securing the housing. A protective component is connected to both ends of the at least two mounting components. At least a portion of the protective component is positioned opposite to or within the fixed space, and it abuts against the end of the housing away from the working base surface. The width of the mounting component gradually decreases from the end of the protective component near the fixed space to the end away from the fixed space, forming a guide surface on the side of the mounting component away from the fixed space. Thus, the operator first places the electrical components used for communication into the receiving cavity of the housing, and then fixes the housing to the wall inside the high-speed rail tunnel. Next, the two mounting components are positioned on opposite sides of the housing along the first preset direction, and their positions are adjusted so that at least a portion of the housing is located within the fixed space formed by the two components, until the two mounting components are tightly abutted against the sides of the housing, and then the mounting components are locked in place. Therefore, after the enclosure is fixed to the wall, it is further secured laterally from both sides. Then, the workers connect the two ends of the protective component to the two fixing components, so that the protective structure abuts against the end of the enclosure away from the wall, forming a physical protective beam that reliably confines the enclosure to the wall. This prevents the enclosure from falling off the wall and reduces the probability of the enclosure door being accidentally opened by strong winds. Simultaneously, because the fixing component is angled away from the enclosure, it forms a guide surface. When piston-like winds occur in the tunnel and directly impact the enclosure, this guide surface buffers and guides the airflow. The airflow guided by the guide surface blows towards the protective structure, which further buffers the direct impact of the airflow on the enclosure, thus significantly reducing the damage of wind pressure loads to the enclosure and its internal electrical components. This ensures the operational reliability of the electrical components inside the enclosure, thereby solving the problem of low operational reliability of communication enclosures in high-speed rail tunnels due to piston-like winds in existing technologies.
