Description

Technical Field

[0001] This invention relates to the field of bridge engineering and environmental control technology, specifically to a fog-removing and wind-proofing structure and operation method for a cross-valley bridge. Background Technology

[0002] Cross-valley bridges are mostly built in canyons or mountainous areas. In high-altitude regions with steep valley terrain, their operation faces the dual challenges of valley fog and strong crosswinds. Valley fog is frequent and concentrated, especially at night and in rainy or foggy weather, significantly reducing visibility and seriously affecting driving safety. At the same time, strong crosswinds are often present in valley areas, threatening vehicle stability. Existing wind-resistant measures mainly focus on optimizing the aerodynamic performance of the bridge structure itself, such as installing wind barriers or adjusting the structural shape, but these are difficult to completely eliminate the effects of crosswinds. Fog removal measures mostly use spraying defogging agents or mechanical ventilation, which suffer from high costs, low efficiency, and the inability to monitor and adjust in real time, and are difficult to adapt to large-scale, high-frequency valley fog environments. Traditional bridge designs often lack comprehensive protective measures against fog and strong crosswinds, resulting in significant safety hazards. Summary of the Invention

[0003] The main objective of this invention is to provide a fog-proof and wind-proof structure for cross-valley bridges, which addresses the problem that traditional bridge designs often lack comprehensive protective measures against fog and strong crosswinds, leading to significant safety hazards.

[0004] To achieve the above objectives, the present invention provides a fog-removing and wind-proof structure for cross-valley bridges, comprising: The support assembly includes a support frame connected to the bridge and multiple sets of closures installed on the support frame; a driving space is formed between the support frame and the bridge, and support rods are provided on both sides of the support frame; The air guiding assembly includes a drive component movably disposed on both sides of the support frame, a first air guiding component and a second air guiding component movably connected to the drive component; the adjacent ends of the first air guiding component and the second air guiding component are respectively movably connected to the support rod; the drive component extends or shortens under the action of external force, so that the first air guiding component and the second air guiding component swing about the support rod in a direction away from the support frame and are located on the same vertical plane, or swing about the support rod in a direction close to the support frame and form a triangular support with the support frame; The end-sealing assembly includes a lifting member disposed on the top of a support frame and an end-sealing member movably disposed on the top of the support frame; the lifting member and the end-sealing member are movably connected; under the action of an external force, the lifting member drives the end-sealing member to swing around the support frame as the center, so that the end-sealing member fits against the top of the support frame to close the top of the driving space, or separates the end-sealing member from the top of the support frame to open the top of the driving space. The defogging assembly includes an air supply component mounted on a support frame and a defogging component mounted within the support frame; the air supply component contains a heating element; the defogging component is arranged along the axial direction of the travel space.

[0005] As a further improvement of the present invention, the support frame includes steel columns arranged on both sides of the bridge, longitudinal steel beams arranged on the steel columns, and transverse steel beams connecting the ends of the steel columns; an installation space is formed between the steel columns and the longitudinal steel beams; the closure element is a glass curtain wall arranged within the installation space.

[0006] As a further improvement of the present invention, the support rod is installed in the middle of the steel column and is arranged parallel to the horizontal plane.

[0007] As a further improvement of the present invention, the driving component includes a first driving rod and a second driving rod movably disposed at the top and bottom of the steel column; the first air guide includes a first air guide plate whose two ends are respectively movably connected to the support rod and the first driving rod; the second air guide includes a second air guide plate whose two ends are respectively movably connected to the support rod and the second driving rod; the first driving rod and the second driving rod extend synchronously to make the first air guide plate and the second air guide plate swing away from the support frame and be in a vertical state; the first driving rod and the second driving rod shorten synchronously to make the first air guide plate and the second air guide plate swing toward the support frame and be in an inclined state.

[0008] As a further improvement of the present invention, it also includes a reinforcing telescopic rod; the reinforcing telescopic rod is respectively disposed between the first air guide plate and the steel column, and between the second air guide plate and the steel column, and the reinforcing telescopic rod is movably connected to the steel column, the first air guide plate, and the second air guide plate respectively.

[0009] As a further improvement of the present invention, the lifting member includes a lifting drive rod movably connected to the supporting beam; the sealing member includes a sealing frame movably connected to the supporting beam; a glass curtain wall is provided inside the sealing frame; and the lifting drive rod is movably connected to the sealing frame.

[0010] As a further improvement of the present invention, the air supply component includes a fan installed on a transverse steel beam; the demisting component includes a pipeline groove arranged on a steel column along the longitudinal direction of the steel beam and a heating transistor disposed in the pipeline groove.

[0011] As a further improvement of the present invention, the heating element includes a heating pipe disposed inside the fan; the end cap frame is provided with a wind speed detection element; and the steel column is provided with a tunnel visibility detection element.

[0012] The present invention discloses an operation method for a fog-removing and wind-proofing structure for a cross-valley bridge, comprising the following modes: Sunny Day Mode: When the wind speed sensor and the tunnel visibility sensor detect that the wind speed and fog concentration are both lower than their respective set thresholds, the end cap frame is automatically opened by controlling the lifting drive rod. At the same time, the first drive rod and the second drive rod move away from the support frame and extend, thereby pushing the first air guide plate and the second air guide plate to rotate into a vertical state to ensure ventilation and lighting.

[0013] Strong wind mode: When the wind speed sensor detects that the wind speed exceeds the set threshold, the end frame is automatically closed by the lifting drive rod to form a semi-closed gate frame. The first drive rod and the second drive rod retract inward, driving the reinforcing telescopic rod to retract, adjusting the first wind guide plate to tilt downward and upward, blocking strong crosswinds from entering the bridge deck driving range.

[0014] Fog Mode: When the tunnel visibility sensor detects that the fog concentration exceeds a set threshold, the lifting drive rod automatically closes the end cap frame, forming a semi-enclosed gate frame. The fan and heating transistor then start operating to begin defogging. The fan draws in outside air, heats it through the heating pipe, and then sends it into the driving space. The heating transistor operates, raising the internal temperature of the driving space, quickly eliminating fog, and improving visibility. The beneficial effects of this invention are reflected in: The enclosed glass canopy structure, composed of a supporting frame, closure components, and sealing components, blocks external fog from entering. Simultaneously, air supply and heating components within the formed space heat the external air before it is introduced into the driving space, further eliminating fog formation in conjunction with defogging components, effectively improving visibility for vehicles on the bridge. The first and second air guide plates, tilted by the drive components, split strong crosswinds in two, directing them towards the top and bottom of the bridge respectively, thus preventing strong crosswinds from directly impacting the bridge's interior. Combined with the glass canopy structure, this effectively resists strong crosswinds, ensuring the safety of the bridge structure and vehicles. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this invention. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0017] See Figure 1 , 2The present invention provides a defogging and windproof structure for a cross-valley bridge 1, comprising a support component, a wind guide component, an end-sealing component, and a defogging component.

[0018] The support assembly includes a support frame 2 connected to the bridge 1, multiple sets of closures 3 mounted on the support frame 2, a driving space 4 formed between the support frame 2 and the bridge 1, and support rods 5 on both sides of the support frame 2. The air guiding assembly includes a drive member 6 movably mounted on both sides of the support frame 2, a first air guide member 7 and a second air guide member 8 movably connected to the drive member 6, and adjacent ends of the first air guide member 7 and the second air guide member 8 movably connected to the support rods 5. The drive member 6 extends or shortens under external force, so that the first air guide member 7 and the second air guide member 8 swing about the support rod 5 away from the support frame 2 and are located on the same vertical plane, or about the support rod 5 towards the adjacent support frame. The direction of the swing is 2 and forms a triangular support with the support frame 2; the end sealing assembly includes a lifting member 9 set on the top of the support frame 2 and an end sealing member 10 movably set on the top of the support frame 2. The lifting member 9 and the end sealing member 10 are movably connected. Under the action of external force, the lifting member 9 drives the end sealing member 10 to swing around the support frame 2 as the center, so that the end sealing member 10 and the top of the support frame 2 are in contact to close the top of the travel space 4, or the end sealing member 10 is separated from the top of the support frame 2 to open the top of the travel space 4; the defogging assembly includes an air supply member 11 set on the support frame 2 and a defogging member 12 set in the support. The air supply member 11 is provided with a heating member 13. The defogging member 12 is arranged along the axial direction of the travel space 4.

[0019] Further, see Figure 1 , 2 3. The supporting frame 2 includes steel columns 201 set on both sides of the bridge 1, longitudinal steel beams 202 set on the steel columns 201, and transverse steel beams 203 connecting the ends of the steel columns 201. An installation space 204 is formed between the steel columns 201 and the longitudinal steel beams 202. The enclosure 3 is a glass curtain wall set in the installation space 204.

[0020] Preferably, multiple sets of steel columns 201 are arranged at intervals along the axial direction of the bridge 1, and the steel columns 201 on both sides of the bridge 1 are arranged opposite each other.

[0021] Preferred, see Figure 1 , 67. A pre-embedded steel plate 14 is embedded in the bridge 1. A connecting stud 15 is welded on the pre-embedded steel plate 14. The connecting stud 15 is made of high-strength bolts. A base plate 16 is welded to the bottom end of the steel column 201. A connecting hole 17 is provided on the base plate 16. The base plate 16 is located on the pre-embedded steel plate 14. An elastic washer 18 is also provided between the base plate 16 and the pre-embedded steel plate 14. The connecting stud 15 passes through the connecting hole 17 and is provided with a washer 19 and a nut 20. By rotating the nut 20, it is threadedly connected to the connecting stud 15, thereby connecting the base plate 16 and the pre-embedded steel plate 14, so that the steel column 201 is stably connected to the bridge 1.

[0022] Preferably, the longitudinal steel beams 202 are welded between two adjacent sets of steel columns 201, and the upper and lower sets of longitudinal steel beams 202 and the left and right sets of steel columns 201 form a rectangular installation space 204.

[0023] It should be noted that the steel columns 201, horizontal steel beams 203, longitudinal steel beams 202, and glass curtain walls are interconnected to form the steel frame structure of the glass opening structure. The spacing between each component can be reasonably designed according to the length of the opening structure and the actual needs of the site. After the glass curtain wall is installed on the support frame 2, the glass curtain wall and the support frame 2 are sealed with sealing strips.

[0024] It should be noted that the steel columns 201 on both sides of the bridge 1 form a doorway-shaped structure with the transverse steel beams 203. The steel columns 201 on both sides of the bridge 1 are connected by the transverse steel beams 203, and the overall structure of the support frame 2 is made more stable by the connection of the longitudinal steel beams 202.

[0025] In the above setup, steel columns 201 are installed on both sides of bridge 1 and connected to the transverse steel beams 203 and longitudinal steel beams 202 to form a stable support frame 2 structure, which surrounds the bridge 1 section in the crosswind and fog environment. Tempered glass curtain walls are installed on both sides of the support frame 2. While providing wind protection and defogging, the glass curtain walls allow for viewing the scenery on both sides of bridge 1 without causing obstruction after installation.

[0026] Further, see Figure 1 , 2 The support rod 5 is installed in the middle of the steel column 201, and the support rod 5 is set parallel to the horizontal plane.

[0027] Preferably, the support rod 5 is made of high-strength steel and can be welded to the steel column 201.

[0028] Further, see Figure 1 , 2The driving component 6 includes a first driving rod 601 and a second driving rod 602 movably disposed at the top and bottom of the steel column 201. The first air guide component 7 includes a first air guide plate 701 whose two ends are respectively movably connected to the support rod 5 and the first driving rod 601. The second air guide component 8 includes a second air guide plate 801 whose two ends are respectively movably connected to the support rod 5 and the second driving rod 602. The first driving rod 601 and the second driving rod 602 extend synchronously to make the first air guide plate 701 and the second air guide plate 801 swing away from the support frame 2 and be in a vertical state. The first driving rod 601 and the second driving rod 602 shorten synchronously to make the first air guide plate 701 and the second air guide plate 801 swing toward the support frame 2 and be in an inclined state.

[0029] Preferred, see Figure 5 Both the first drive rod 601 and the second drive rod 602 are electric telescopic rods in the existing structure. The two ends of the first drive rod 601 and the second drive rod 602 and the end of the support rod 5 are respectively provided with rotating sleeves 21.

[0030] Preferred, see Figure 9 , 10 The steel column 201, the first air guide plate 701, and the second air guide plate 801 are respectively provided with "U"-shaped connecting frames 22. The connecting frames 22 are provided with rotating shafts 23, which are rotatably connected to the rotating sleeve 21.

[0031] Preferred, see Figure 4 The first air guide plate 701 includes an outer rectangular air guide frame 7011 and a high-strength polycarbonate transparent plate 7012 located inside the air guide frame 7011. The connecting frame 22 is welded to the air guide frame 7011, and adjacent air guide frames 7011 are connected by bolts. The structure of the second air guide plate 801 is the same as that of the first air guide plate 701.

[0032] In the above configuration, during the synchronous extension of the first drive rod 601 and the second drive rod 602, the first drive rod 601 drives the first air guide plate 701 to swing away from the support frame 2. The end of the first air guide plate 701 that is rotatably connected to the support rod 5 can only rotate circumferentially. After the first air guide plate 701 swings, when the first air guide plate 701 is vertical (perpendicular to the support rod 5 after swinging), the first air guide plate 701 is in a normal state and does not have air guiding properties. The movement of the second air guide plate 801 is the same as that of the first air guide plate 701. During the movement of the first air guide plate 701, the second air guide plate 801 is pushed by the second drive rod 602 and moves accordingly. When both the first air guide plate 701 and the second air guide plate 801 are in a vertical state, they are in a normal state and do not have air guiding properties. When the first drive rod 601 and the second drive rod 602 retract... When the short rods drive the first air guide plate 701 and the second air guide plate 801 to swing towards the support frame 2 and tilt, the end of the first air guide plate 701 away from the support rod 5 is close to the top of the support frame 2, and the end of the second air guide plate 801 away from the support rod 5 is close to the top of the support frame 2. At this time, the first air guide plate 701, the second air guide plate 801 and the support frame 2 form a triangular structure, which is in the open state and has windproof properties. When the crosswind blows from the side of the bridge 1, the crosswind is divided into two parts. One part moves upward along the first air guide plate 701 towards the top of the support frame 2, and the other part moves downward along the second air guide plate 801 towards the bottom of the bridge 1. The support rod 5 provides the most important support for the first air guide plate 701 and the second air guide plate 801, and together with the first drive rod 601 and the second drive rod 602, the force generated by the crosswind is transmitted to the steel column 201.

[0033] In one embodiment, see Figure 1 , 2 To improve the support performance of the first air guide plate 701 and the second air guide plate 801, a reinforcing telescopic rod 24 is also provided. The reinforcing telescopic rod 24 is respectively set between the first air guide plate 701 and the steel column 201, and between the second air guide plate 801 and the steel column 201. The reinforcing telescopic rod 24 is movably connected to the steel column 201, the first air guide plate 701, and the second air guide plate 801.

[0034] Preferably, the reinforced telescopic rod 24 is a telescopic rod with a mechanical structure, which does not require electric drive. The connection method between the reinforced telescopic rod 24 and the steel column 201, the first air guide plate 701, and the second air guide plate 801 is the same as the connection method between the first drive rod 601 and the first air guide plate 701.

[0035] Preferably, the reinforcing telescopic rod 24 is arranged parallel to the first drive rod 601 and the second drive rod 602 respectively. During the swinging process of the first air guide plate 701 and the second air guide plate 801, the reinforcing telescopic rod 24 extends or shortens accordingly. The reinforcing telescopic rod 24 is mainly used to improve the support stability of the first air guide plate 701 and the second air guide plate 801.

[0036] In one embodiment, see Figure 1 , 2 The lifting component 9 includes a lifting drive rod 901 that is movably connected to the supporting beam; the sealing component 10 includes a sealing frame 1001 that is movably connected to the supporting beam, and the sealing frame 1001 is provided with a glass curtain wall; the lifting drive rod 901 is movably connected to the sealing frame 1001.

[0037] Preferably, the end capping frame 1001 is a rectangular frame of steel structure. Both the end capping frame 1001 and the supporting crossbeam are provided with connecting frames 22. The connecting frames 22 are also provided with rotating shafts 23. The lifting drive rod 901 is electrically driven. Both ends of the lifting drive rod 901 are provided with rotating sleeves 21. The rotating sleeves 21 are rotatably connected to the rotating shafts 23. The way in which the two ends of the lifting drive rod 901 are movably connected to the supporting crossbeam and the end capping frame 1001 is the same as the way in which the first drive rod 601, the first air guide plate 701, and the steel column 201 are movably connected.

[0038] Preferably, the installation method of the glass curtain wall and the end frame 1001 is the same as the installation method of the support frame 2.

[0039] Preferably, the end cap frame 1001 and the support beam can be connected by a hinge 25.

[0040] When the lifting drive rod 901 is working, the lifting drive rod 901 extends and pushes the end capping frame 1001 to rotate. Two sets of end capping frames 1001 can be set. The two ends of the two sets of end capping frames 1001 are connected to the support frame 2 in two movable connections. During the process of the lifting drive rod 901 driving the end capping frame 1001 to rotate, the end capping frame 1001 moves away from the support frame 2, thereby opening the top of the support frame 2. This is suitable for sunny days without crosswinds or heavy fog. In the presence of crosswinds or heavy fog, the lifting drive rod 901 shortens and drives the end capping frame 1001 to rotate and contact the top of the support frame 2, thus closing the top of the support frame 2.

[0041] In one embodiment, see Figure 1 , 2 The air supply component 11 includes a fan 1101 installed on the transverse steel beam 203, and the demisting component 12 includes a pipeline trough 1201 arranged on the steel column 201 along the longitudinal steel beam 202 direction and a heating transistor 1202 disposed in the pipeline trough 1201.

[0042] Preferred, see Figure 1 ,8 A longitudinal insulating conduit 26 is arranged on the steel column 201 along the direction of the bridge 1, and a vertical insulating conduit 27 is arranged along the axial direction of the steel column 201. Wires are run through the longitudinal insulating conduit 26 and the vertical insulating conduit 27 and electrically connected to the heating transistor 1202. Heating by the heating transistor 1202 can heat and defog the driving space 4.

[0043] Preferred, see Figure 8 The pipeline trough 1201 has an "L" shaped structure and is bolted to the inner side of the steel column 201 facing the bridge 1.

[0044] Further, see Figure 1 , 2 The heating element 13 includes a heating pipe installed inside the fan 1101; the end frame 1001 is provided with a wind speed detection element 28, and the steel column 201 is provided with a tunnel visibility detection element 29.

[0045] Preferably, the heating tube has an existing structure, the wind speed detection component 28 adopts a wind speed sensor, which is fixed to the end frame 1001 by the central vertical rod 30 to monitor the on-site wind speed in real time; the tunnel visibility detection component 29 adopts a tunnel visibility detection sensor.

[0046] The tunnel visibility detector is fixed to the steel column 201 with bolts. The left and right sides are fixed at the same position and height, with an installation height of 2m. The tunnel visibility detector's circuit is connected to the vertical insulated conduit 27 to monitor the visibility inside the tunnel structure in real time.

[0047] It should be noted that a control system is required to control the operation of the aforementioned first drive rod 601, second drive rod 602, and lifting drive rod 901. The control system can be a PLC or a microcontroller system. The control system is electrically connected to the first drive rod 601, second drive rod 602, lifting drive rod 901, fan 1101, heating transistor 1202, heating tube, wind speed sensor, and visibility sensor. The wind speed sensor monitors the crosswind speed outside bridge 1. When the wind speed reaches the threshold set by the wind speed sensor, a signal is transmitted to the control system, which then controls the first drive rod 601 and second drive rod 602 to shorten, causing the first drive rod 601 to shorten. The air guide plate 701 and the second air guide plate 801 are tilted and form a triangular support with the steel column 201, which divides the crosswind into two parts, thereby reducing the force of the crosswind on the support frame 2. When the visibility detection sensor detects that the visibility in the driving space 4 is lower than the set threshold, it transmits the signal to the control system. The control system controls the fan 1101 to turn on, and at the same time the heater and heating transistor 1202 are energized to heat. The fan 1101 blows hot air into the driving space 4, and the heating transistor 1202 heats the interior of the driving space 4. Under the dual action of the fan 1101 and the heating transistor 1202, the visibility in the driving space 4 is maintained.

[0048] It should be noted that the entire device can be powered by an external circuit or by installing flexible photovoltaic modules on the glass curtain wall of the end frame 1001. The inverters and batteries that are compatible with the flexible photovoltaic modules are all mature technologies, and they can be set up according to their required installation and connection methods.

[0049] In one embodiment, a method for operating the fog-removing and wind-proof structure of a cross-valley bridge 1 is proposed, including the following modes: Sunny Day Mode: When the wind speed sensor and tunnel visibility sensor detect that the wind speed and fog concentration are both lower than their respective set thresholds, the end cap frame 1001 is automatically opened by lifting the drive rod 901. At the same time, the first drive rod 601 and the second drive rod 602 move away from the support frame 2 and extend, thereby pushing the first air guide plate 701 and the second air guide plate 801 to rotate into a vertical state to ensure ventilation and lighting.

[0050] Strong wind mode: When the wind speed sensor detects that the wind speed exceeds the set threshold, the end frame 1001 is automatically closed by raising the drive rod 901 to form a semi-closed gate frame. The first drive rod 601 and the second drive rod 602 retract inward, driving the reinforcing telescopic rod 24 to retract. The first wind guide plate 701 is adjusted to tilt downward and upward, blocking strong crosswinds from entering the bridge surface driving range.

[0051] Fog Mode: When the tunnel visibility sensor detects that the fog concentration exceeds the set threshold, the end cap frame 1001 is automatically closed by raising the drive rod 901 to form a semi-enclosed door frame. The fan 1101 and the heating transistor 1202 are then started to begin defogging. The fan 1101 draws in outside air, heats it through the heating pipe, and then sends it into the driving space 4. The heating transistor 1202 operates to increase the internal temperature of the driving space 4, quickly eliminating fog and improving visibility.

[0052] During operation, six modules work collaboratively: the main body of the glass canopy consisting of the supporting frame 2, the end cap frame 1001, and the glass curtain wall; the intelligent defogging system consisting of the fan 1101 and the heating transistor 1202; the environmental monitoring module consisting of the wind speed sensor and the tunnel visibility sensor; and the energy supply system consisting of a microcontroller or PLC control unit and flexible photovoltaic modules or external circuits. The energy supply system continuously maintains the operation of the electrical equipment in each module. The visibility sensor and wind speed sensor included in the environmental monitoring module collect real-time data on the bridge deck and surrounding environment, transmit the data using wireless communication technology, and provide the control unit with accurate bridge deck visibility and wind speed changes.

9. A method for operating a defogging and windproof structure for a cross-valley bridge according to any one of claims 1-8, comprising the following modes: Sunny Day Mode: When the wind speed sensor and the tunnel visibility sensor detect that the wind speed and fog concentration are both lower than their respective set thresholds, the end cap frame (1001) is automatically opened by the lifting drive rod (901). At the same time, the first drive rod (601) and the second drive rod (602) move away from the support frame (2) and extend, thereby pushing the first air guide plate (701) and the second air guide plate (801) to rotate into a vertical state to ensure ventilation and lighting. Strong wind mode: When the wind speed sensor detects that the wind speed exceeds the set threshold, the end frame (1001) is automatically closed by the lifting drive rod (901) to form a semi-closed door frame. The first drive rod (601) and the second drive rod (602) retract inward, driving the reinforcing telescopic rod (24) to retract, adjusting the first wind guide plate (701) to tilt downward and the first wind guide plate (701) to tilt upward, blocking strong crosswinds from entering the bridge surface driving range; Fog mode: When the tunnel visibility sensor detects that the fog concentration exceeds the set threshold, the end cap frame (1001) is automatically closed by the lifting drive rod (901) to form a semi-closed door frame, and the fan (1101) and the heating transistor (1202) are started to start defogging. The fan (1101) draws in the outside air, heats it through the heating pipe and sends it into the driving space (4). The heating transistor (1202) operates to increase the internal temperature of the driving space (4), quickly eliminate fog and improve visibility.
