Description

Technical Field

[0001] This invention relates to the field of fencing, and more particularly to a construction site fencing system and its operating method. Background Technology

[0002] Construction site fences are important safety and management facilities at construction sites. Their core function is to isolate the construction area from the external environment, prevent unauthorized personnel and vehicles from entering and causing safety accidents or disrupting the construction order, and at the same time, they can reduce the impact of construction noise and dust on the outside world to a certain extent. They form a closed or semi-closed protective barrier, creating a relatively independent working space for the construction site.

[0003] To reduce the space occupied by the gates on the sides of the fence and avoid interfering with vehicle access, existing technologies often use sliding gates for construction site fences. The gate panels run on the upper load-bearing track or the lower guide track, and are commonly electrically driven, but can also be manually operated. The gate body is mostly made of color steel composite panels or metal fences, and can be linked with buttons, remote control, or external systems to enable passage. It is suitable for the main entrances and exits of construction sites where vehicles frequently pass through.

[0004] However, when using the above technical solutions, on the one hand, the sliding gate has a long moving distance when opening and closing, which affects the opening and closing efficiency. On the other hand, when drivers drive in and out of the gate, especially when they need to turn around to enter or exit, there is no corresponding reference at the gate. Furthermore, due to the limited field of vision and the driver's skill level, it is difficult to drive along the left or right side of the gate. They may only realize that other vehicles are about to enter or exit when they are close to the gate, and they need to adjust their direction again to avoid interference and collision. They may even need to reverse, which causes traffic congestion at the construction site gate, low entry and exit efficiency, and also poses certain safety risks. Summary of the Invention

[0005] To address the technical problem of low efficiency in vehicle entry and exit from construction site fences in the prior art, this invention provides a construction site fence system and its operating method, which can divert vehicles entering and exiting, avoid drivers having to adjust their driving direction multiple times, and improve the efficiency of entering and exiting the fence.

[0006] In a first aspect, the present invention provides a construction site fence system to solve the above-mentioned technical problems, including a fence body, an entrance and exit provided on the fence body, an upper guide groove and a lower guide groove horizontally provided on the entrance and exit, a door assembly one and a door assembly two provided between the upper guide groove and the lower guide groove, each of the door assembly one and the door assembly two including a roller shutter door and a roller shaft, the roller shaft being vertically and rotatably disposed between the upper guide groove and the lower guide groove, the roller shaft being connected to a driving device, the roller shutter door being able to move along the upper guide groove and the lower guide groove under the drive of the roller shaft, the roller shutter door being able to roll up to the middle position of the entrance and exit, and after the two roller shutter doors are rolled up, the entrance and exit are divided into an entrance and an exit.

[0007] This invention, by setting two sets of roller shutter doors in the middle of the entrance and exit, driven by vertical rollers and horizontally unfolding and retracting along the upper and lower guide grooves, not only realizes the rapid opening and closing of the door to improve traffic efficiency, but also naturally forms a clearly separated entrance and exit channel when retracted. This allows the door to integrate the function of diverting and guiding vehicles, effectively guiding vehicles to travel in one direction, avoiding collisions between vehicles, reversing adjustments, and traffic congestion, and significantly enhancing the safety and traffic order of the construction site entrance and exit.

[0008] Furthermore, a mounting beam is horizontally arranged on the inlet and outlet, and the driving device is arranged on the mounting beam. The driving device includes a drive motor, which is mounted on the mounting beam. The drive motor is connected to a transmission assembly, which is connected to a drive gear one. The drive gear one is rotatably mounted on the mounting beam. The drive gear one meshes with a drive gear two, which is also rotatably mounted on the mounting beam. Both drive gear one and drive gear two have a bevel gear one coaxially arranged at one end. The bevel gear one meshes with the bevel gear two at the upper end of the scroll, and the bevel gear two can drive the corresponding scroll to rotate.

[0009] This invention uses a single drive motor to rotate and unfold two roller shutter doors, simplifying the structure while ensuring synchronous movement of the two roller shutter doors.

[0010] Furthermore, a mounting seat is provided in the middle of the mounting beam. The mounting seat has an upward-opening U-shaped structure. The second drive gear is rotatably mounted in the mounting seat. The first drive gear and the corresponding first bevel gear are both mounted on the transmission shaft. The first drive gear and the transmission shaft are an integral structure. The end of the transmission shaft is connected to the transmission assembly. A clutch sleeve is provided on the mounting seat. The transmission shaft passes through the clutch sleeve. A clutch assembly is provided between the end face of the clutch sleeve and the first drive gear. The clutch assembly can drive the first drive gear to move axially. The transmission shaft can rotate and move axially relative to the clutch sleeve. When the transmission shaft moves, the coaxial first bevel gear no longer meshes with the corresponding second bevel gear, and the first drive gear no longer meshes with the second drive gear. A drive hole is provided at the upper end of the reel for inserting a manual lever.

[0011] This invention, by setting up a clutch sleeve and clutch assembly, enables the door to be opened and closed manually in the event of a power outage or failure of the drive motor or transmission components. Under power outages, malfunctions, or special working conditions, it can quickly switch to manual operation without disassembling the transmission components, improving the reliability, safety, and ease of maintenance of the system. At the same time, the structure is compact and the positioning is precise, ensuring a stable and reliable gear meshing state.

[0012] Furthermore, the clutch assembly includes an electromagnetic coil, which is electrically connected to the battery via a manual switch. A magnet is provided on the corresponding end face of the drive gear. When the electromagnetic coil is energized, it can attract the magnet, and the transmission axis moves away from the spool.

[0013] Furthermore, the manual switch includes two single-pole double-throw switches. The two power terminals of the single-pole double-throw switches are electrically connected to the two ends of the storage battery, respectively. The control terminal of the single-pole double-throw switch is electrically connected to the corresponding terminal of the electromagnetic coil. A limit plate is also provided on the drive shaft near the bevel gear. When the roller shutter door rolls up and unfolds, the electromagnetic coil and the magnet repel each other, and the limit plate can contact the inner surface of the mounting base.

[0014] This invention uses two single-pole double-throw switches to control the direction of the electromagnetic coil's magnetic poles, thereby changing the direction of the force applied to the first drive gear. This ensures smooth disconnection when the transmission is disengaged. During transmission, the limit plate, in conjunction with the limit plate, can limit the transmission shaft to prevent axial movement, ensuring the meshing of the first drive gear and the second drive gear, and ensuring the synchronous movement of the two roller shutter doors.

[0015] Furthermore, the mounting base includes two upright plates, and multiple balls are rolled on the end face of the limiting plate near the mounting base. The balls can generate rolling friction with the corresponding upright plates. The upright plates are provided with shaft holes, and the transmission shaft passes through the shaft holes. A bearing bush is provided in the shaft hole near the first bevel gear, and the clutch sleeve is provided in the shaft hole away from the first bevel gear.

[0016] Furthermore, the drive motor is horizontally positioned, and the transmission assembly includes a first rotating handle and a second rotating handle, which are Z-shaped. The upper end of the first rotating handle is hinged to the output shaft of the drive motor, and the lower end of the first rotating handle is hinged to the upper support of the transition shaft via an upper pin. The lower support of the transition shaft is hinged to the upper end of the second rotating handle via a lower pin. Both the upper and lower pins are horizontally positioned and perpendicular to each other. The lower end of the second rotating handle is hinged to the transmission shaft. An upper fixed handle is provided between the transition shaft and the output shaft, and the two ends of the upper fixed handle are rotatably connected to the output shaft and the transition shaft, respectively. A lower fixed handle is also provided between the transition shaft and the transmission shaft, and the two ends of the lower fixed handle are rotatably connected to the transmission shaft and the transition shaft, respectively.

[0017] This invention uses a rotating handle one and a rotating handle two, along with a transition shaft, to transmit power. On one hand, it changes the direction of force transmission, allowing the drive motor to be mounted horizontally on one side. On the other hand, through hinges and rotational connections at various points, it can meet the need for axial movement of the transmission shaft to disconnect the transmission.

[0018] Furthermore, the spool is rotatably mounted on a support base, which is provided with a take-up guide groove. The take-up guide groove has a spiral structure, and the support base is connected to the lower guide groove.

[0019] This invention effectively prevents the roller shutter from falling by setting a support base, ensuring smooth opening and retraction.

[0020] Furthermore, a cleaning shovel is provided at the lower part of the moving end of the roller shutter door, and the cleaning shovel can move along the lower guide groove under the drive of the roller shutter door.

[0021] This invention features a cleaning shovel that removes dirt and other debris from the lower guide groove as the roller shutter opens, ensuring smooth opening of the roller shutter.

[0022] Furthermore, detectors are respectively installed on the mounting beam at positions corresponding to the inlet and outlet. The detectors can detect whether there are vehicles within a set range. Indicator light strips are installed on both sides of the inlet and outlet, as well as between door assembly one and door assembly two. The indicator light strips can change color. The detectors and indicator light strips are all electrically connected to the controller.

[0023] Secondly, the present invention also provides a method for operating a construction site fence system, which includes the following steps: When the detector detects a vehicle within the set range, the indicator light changes to a "Vehicle nearby" indicator color. When the detector detects a vehicle at the entrance or exit, the indicator light changes to a "Vehicle at the entrance" indicator color. When the detector detects no vehicles within the set range or at the entrance or exit, the indicator light changes to a "No vehicle" indicator color. When the drive device cannot drive the spool, the two single-pole double-throw switches are switched, causing the drive shaft to retract. Drive gear one no longer meshes with drive gear two, and bevel gear one on the drive shaft no longer meshes with bevel gear two. The manual lever is then inserted into the spool to drive its rotation.

[0024] This invention provides intuitive and tiered vehicle presence information feedback by setting up detectors to monitor the vehicle status within a set range in real time and linking them with indicator lights. The tiered alerts can provide early warnings before a vehicle approaches the entrance, helping drivers anticipate road conditions and adjust their routes, reducing sudden lane changes, emergency braking, and reversing caused by blind spots or information asymmetry, thereby reducing the probability of conflicts at the entrance and traffic congestion. When the drive unit malfunctions, two single-pole double-throw switches are used to quickly switch, causing the drive shaft to retract and disconnect the meshing of drive gear one and drive gear two with bevel gear one and bevel gear two. The system immediately switches from automatic to manual emergency mode to avoid traffic interruption caused by equipment jamming.

[0025] As can be seen from the above technical solutions, the present invention has the following advantages: This invention provides a construction site fencing system and its operating method. By installing two sets of roller shutter doors at the center of the entrance and exit, driven by vertical rollers and horizontally unfolding and retracting along upper and lower guide grooves, not only is rapid opening and closing of the doors achieved to improve traffic efficiency, but also, in the retracted state, clearly separated entrance and exit channels are naturally formed. This allows the doors to integrate the function of diverting and guiding vehicles, effectively guiding vehicles to travel in one direction, avoiding collisions, reversing adjustments, and traffic congestion, and significantly enhancing the safety and traffic order of the construction site entrance and exit. A single drive motor drives the two roller shutter doors to retract and unfold, simplifying the structure while ensuring the safety of both entrances and exits. The roller shutter door moves synchronously; by incorporating a clutch sleeve and clutch assembly, manual operation can be used to open and close the door in case of power failure or malfunction of the drive motor or transmission components. This allows for quick switching to manual control without disassembling the transmission components during power outages, malfunctions, or special operating conditions, improving system reliability, safety, and ease of maintenance. Simultaneously, the compact structure and precise positioning ensure stable and reliable gear engagement. Two single-pole double-throw switches control the direction of the electromagnetic coil's poles, thereby changing the direction of the force applied to the drive gear, ensuring smooth disengagement when disconnecting the transmission. During operation, it works in conjunction with a limit switch... The positioning plate can limit the drive shaft to prevent axial movement, ensure the meshing of drive gear one and drive gear two, and ensure the synchronous movement of the two roller shutter doors. Power transmission is achieved through the use of handle one and handle two, and a transition shaft. Firstly, the direction of force transmission is changed, allowing the drive motor to be mounted horizontally on one side. Secondly, through various hinges and rotational connections, the axial movement of the drive shaft can be disconnected. A cleaning shovel removes dirt and other debris from the lower guide groove as the roller shutter door opens, ensuring smooth opening. A detector monitors the set range in real time. The system monitors the vehicle's status and displays a series of indicator lights, providing intuitive and tiered feedback on vehicle presence. These tiered alerts offer early warnings as vehicles approach the entrance, helping drivers anticipate road conditions and adjust their routes. This reduces sudden lane changes, emergency braking, and reversing caused by blind spots or information asymmetry, thereby lowering the probability of conflicts at the entrance and reducing traffic congestion. When the drive unit malfunctions, two single-pole double-throw switches quickly switch to retract the drive shaft and disconnect the meshing of drive gear one and drive gear two with bevel gear one and bevel gear two. The system immediately switches from automatic to manual emergency mode, preventing traffic interruptions caused by equipment jamming. Attached Figure Description

[0037] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0038] Example 1 like Figures 1 to 3 As shown, this embodiment provides a construction site fence system, including a fence body 1, a door assembly 2, and a door assembly 3. The fence body 1 is provided with an entrance and exit. The entrance and exit are horizontally provided with an upper guide groove 6 and a lower guide groove 7. The lower guide groove 7 is provided on the foundation, and the upper guide groove 6 is provided above the entrance and exit. The door assembly 2 and the door assembly 3 are provided between the upper guide groove 6 and the lower guide groove 7. Both the door assembly 2 and the door assembly 3 include a roller shutter door 8 and a roller shaft 24. The roller shaft 24 is vertically and rotatably provided between the upper guide groove 6 and the lower guide groove 7. The roller shaft 24 is connected to a drive device 4. The roller shutter door 8 can move along the upper guide groove 6 and the lower guide groove 7 under the drive of the roller shaft 24. The roller shutter door 8 can be rolled up to the middle position of the entrance and exit. After the two roller shutter doors 8 are rolled up, the entrance and exit are divided into an entrance and an exit.

[0039] This embodiment sets up two sets of roller shutter doors 8 at the middle of the entrance and exit, driven by vertical rollers 24 and horizontally unfolding and retracting along the upper and lower guide grooves 7. This not only enables the doors to open and close quickly to improve traffic efficiency, but also naturally forms clearly separated entrance and exit channels when retracted. This allows the doors to integrate the function of diverting and guiding vehicles, effectively guiding vehicles to travel in one direction, avoiding collisions between vehicles, reversing adjustments, and traffic congestion, and significantly enhancing the safety and traffic order of the construction site entrance and exit.

[0040] Because the construction site entrances and exits are opened and closed simultaneously during the designated working hours, such as Figures 1 to 3 and Figure 6As shown, in this embodiment, to achieve synchronous driving of two roller blinds, a mounting beam 5 is horizontally arranged on the inlet and outlet, and a driving device 4 is arranged on the mounting beam 5. The driving device 4 includes a driving motor 10, which is mounted on the mounting beam 5. The driving motor 10 is connected to a transmission assembly 11, which is connected to a driving gear 18. The driving gear 18 is rotatably mounted on the mounting beam 5 and meshes with a driving gear 22. The driving gear 22 is rotatably mounted on the mounting beam 5. A bevel gear 12 is coaxially arranged at one end of both the driving gear 18 and the driving gear 22. The bevel gear 12 meshes with a bevel gear 13 at the upper end of the roller spool 24, and the bevel gear 13 can drive the corresponding roller spool 24 to rotate.

[0041] In this embodiment, the roller shutter door 8 is composed of multiple hinged steel plates. The fixed end of the roller shutter door 8 is hinged to the roller shaft 24. The width of the upper guide groove 6 and the lower guide groove 7 is 2cm to 4cm larger than the thickness of the steel plates. On the one hand, this better guides the roller shutter door 8; on the other hand, it prevents the steel plates from arching and piling up when the roller shutter door 8 is opened, ensuring smooth opening of the roller shutter door 8. Furthermore, since construction vehicles often bring mud or gravel into the lower guide groove 7, affecting the smoothness of opening the roller shutter door 8, therefore, as Figure 8 As shown, in this embodiment, a cleaning shovel 27 is provided at the lower part of the moving end of the roller shutter door 8. The cleaning shovel 27 can move along the lower guide groove 7 under the drive of the roller shutter door 8. The cleaning shovel 27 has a tetrahedral structure. When there is an obstacle in the lower guide groove 7, the cleaning shovel 27 can discharge the obstacle from the lower guide groove 7. When the drive motor 10 rotates, it drives the drive gear 18 to rotate, which in turn drives the drive gear 22, the two bevel gears 12 and 13 to rotate, causing the roller shaft 24 to rotate and roll up the roller shutter door 8. When the drive motor 10 rotates in the opposite direction, the roller shutter door 8 gradually moves and unfolds along the upper and lower guide grooves 7 under the pushing action of the steel plate at the fixed end.

[0042] To prevent the roller shutter door 8 from falling after rolling up, such as Figure 7 As shown, in this embodiment, both the upper guide groove 6 and the lower guide groove 7 are segmented structures. That is, the upper guide groove 6 includes two upper sub-segments, and the lower guide groove 7 includes two lower sub-segments. The two upper sub-segments and the two lower sub-segments respectively support the door assembly 2 and the door assembly 3. The door assembly 2 and the door assembly 3 also include a support base 25. The roller 24 is installed in the support base 25 through bearings. The support base 25 is provided with a spiral winding guide groove 23. The roller 24 is located at the center of the winding guide groove 23. The support base 25 is provided with an opening near the lower sub-segment. The roller shutter door 8 slides into the corresponding lower sub-segment through the opening. The support base 25 is installed on the foundation by bolts.

[0043] In the prior art, when there is a power outage or the drive motor 10 or transmission assembly 11 malfunctions and cannot drive the roller 24 to rotate, the transmission assembly 11 needs to be removed to roll up and unroll the roller shutter door 8, which is quite inconvenient to use. Therefore, in this embodiment, as Figure 5 , Figure 6 and Figure 9 As shown, a mounting base 9 is provided in the middle of the mounting beam 5. The mounting base 9 has an upward-opening U-shaped structure. The second drive gear 22 is rotatably mounted in the mounting base via a shaft and bearings. The first drive gear 18 and the corresponding bevel gear 12 are both mounted on the transmission shaft 14. The first drive gear 18 and the transmission shaft 14 are an integral structure. The end of the transmission shaft 14 is connected to the transmission assembly 11. A clutch sleeve 15 is provided on the mounting base 9. The transmission shaft 14 passes through the clutch sleeve 15. A clutch assembly 20 is provided between the end face of the clutch sleeve 15 and the first drive gear 18. The clutch assembly 20 can drive the first drive gear 18 to move axially. The transmission shaft 14 can rotate and move axially relative to the clutch sleeve 15. When the transmission shaft 14 moves, the coaxial bevel gear 12 no longer meshes with the corresponding bevel gear 13, and the first drive gear 18 no longer meshes with the second drive gear 22. A drive hole is provided at the upper end of the reel 24. 31. The drive hole 31 can be configured as a hexagonal structure. The drive hole 31 is used to insert a manual lever. Specifically, the clutch assembly 20 includes an electromagnetic coil 16. The electromagnetic coil 16 is electrically connected to the battery 29 through a manual switch. A magnet 17 is provided on the corresponding end face of the drive gear 18. When the electromagnetic coil 16 is energized, it can attract the magnet 17. The transmission shaft 14 moves away from the scroll 24. When there is a power outage or the drive motor 10 fails, the clutch assembly 20 drives the transmission shaft 14 to move axially. The bevel gear 12 does not mesh with the bevel gear 13, and the drive gear 18 no longer meshes with the drive gear 22. Then, a T-shaped manual lever is inserted into the drive hole 31 at the top of the scroll 24. Under manual operation, the scroll 24 is rotated to realize the opening and closing of the door. This does not affect the door assembly 2 and the door assembly 3 in their function of door opening and diversion during operation. After maintenance or power restoration, the transmission shaft 14 can be reset to realize transmission.

[0044] Furthermore, such as Figure 9As shown, the manual switch includes two single-pole double-throw switches 28. The two power terminals of the single-pole double-throw switches 28 are electrically connected to the two ends of the storage battery 29, respectively. The control terminal of the single-pole double-throw switches 28 is electrically connected to the corresponding terminal of the electromagnetic coil 16. A limit plate 19 is also provided on the drive shaft 14 near the bevel gear 12. When the roller shutter door 8 rolls up and unfolds, the electromagnetic coil 16 and the magnet 17 repel each other, and the limit plate 19 can contact the inner surface of the mounting base 9. By using the two single-pole double-throw switches 28, the magnetic direction of the electromagnetic coil 16 can be changed, so that the electromagnetic coil 16 and the electromagnet 17 generate mutual attraction or repulsion, ensuring that the transmission can be smoothly disconnected when it is disconnected. During transmission, the limit plate 19 can limit the drive shaft 14 to prevent its axial movement, ensure the meshing of the drive gear 18 and the drive gear 22, and ensure that the two roller shutter doors 8 move synchronously.

[0045] In order to enable the drive shaft 14 to move axially, such as Figure 2 and Figure 4 As shown, in this embodiment, the drive motor 10 is horizontally arranged, and the transmission assembly 11 includes a first rotating handle 1101 and a second rotating handle 1102. The first rotating handle 1101 and the second rotating handle 1102 have a Z-shaped structure. The upper end of the first rotating handle 1101 is hinged to the output shaft of the drive motor 10, and the lower end of the first rotating handle 1101 is hinged to the upper support of the transition shaft 1105 via an upper pin 1106. The lower support of the transition shaft 1105 is hinged to the upper end of the second rotating handle 1102 via a lower pin 1107. The upper pin 1106 and the lower pin 1107 are both horizontally arranged and perpendicular to each other. The lower end of the second rotating handle 1102 is hinged to the transmission shaft 14. An upper fixing handle 1104 is provided between shaft 1105 and the output shaft. The two ends of the upper fixing handle are rotatably connected to the output shaft and the transition shaft 1105, respectively. A lower fixing handle 1103 is also provided between the transition shaft 1105 and the transmission shaft 14. The two ends of the lower fixing handle 1103 are rotatably connected to the transmission shaft 14 and the transition shaft 1105, respectively. By using the first rotating handle 1101 and the second rotating handle 1102 and the transition shaft 1105 for power transmission, the direction of force transmission is changed, so that the drive motor 10 is horizontally mounted on one side. Secondly, through various hinges and rotational connections, the need for axial movement of the transmission shaft 14 to disconnect the transmission can be met.

[0046] To enhance the intelligence of this fencing system's operation, such as Figure 1As shown, in this embodiment, detectors are respectively installed on the mounting beam 5 at positions corresponding to the inlet and outlet. The detectors can detect whether there are vehicles within a set range. Indicator light strips 26 are installed on both sides of the inlet and outlet, as well as between the door assembly 2 and the door assembly 3. The indicator light strips 26 can change color. The detectors and indicator light strips 26 are electrically connected to the controller. In this embodiment, the detector uses a high-definition intelligent camera with vehicle recognition software, which can clearly and accurately detect whether there are vehicles passing through the set area. The indicator light strips 26 have three color changes: red indicates that there are vehicles at the inlet and outlet, yellow indicates that there are vehicles within the detection range, and green indicates that there are no vehicles within the monitoring range and at the inlet and outlet.

[0047] In this embodiment, the controller also includes a remote control module, which is wirelessly connected to a remote control. When the operator controls the drive motor 10 via the remote control, the door assembly 1 and the door assembly 2 and 3 are opened and closed.

[0048] In this embodiment, the mounting base 9 includes two upright plates. A plurality of balls 21 are rolled on the end face of the limiting plate 19 near the mounting base 9. The balls 21 can generate rolling friction with the corresponding upright plates. The upright plates are provided with shaft holes. The transmission shaft 14 passes through the shaft holes. A bearing bush is provided in the shaft hole near the bevel gear 12, and the clutch sleeve 15 is provided in the shaft hole away from the bevel gear 12.

[0049] Example 2 This embodiment provides a method for operating a construction site fence system, which includes the following steps: When the detector detects a vehicle within the set range, the indicator light strip 26 changes to the indicator color of "Vehicle nearby". When the detector detects a vehicle at the entrance or exit, the indicator light strip 26 changes to the indicator color of "Vehicle at the entrance". When the detector detects no vehicles within the set range or at the entrance or exit, the indicator light strip 26 changes to the indicator color of "No vehicle". This embodiment uses detectors to monitor the vehicle status within a set range in real time and links them with indicator lights 26 to provide intuitive and tiered feedback on vehicle presence. Tiered alerts can provide early warnings before vehicles approach the gate, helping drivers anticipate road conditions and adjust their routes, reducing sudden lane changes, emergency braking, and reversing caused by blind spots or information asymmetry, thereby reducing the probability of conflicts and traffic congestion at the gate. At the same time, the clear display of the "no vehicle" status can assist management personnel or the system in determining whether to allow the gate to close, avoiding vehicles being trapped or the opening time being extended due to misjudgment, thus improving traffic safety and the accuracy of automated control. This design closely integrates environmental perception with human-machine interaction, and the information transmission is simple and efficient. In high-frequency access scenarios at construction sites, it can significantly improve vehicle dispatching efficiency and on-site order management. When the drive unit 4 malfunctions, two single-pole double-throw switches 28 are used to quickly switch, causing the drive shaft 14 to retract and disconnect the meshing of drive gear 18 and drive gear 22, as well as bevel gear 12 and bevel gear 23. The system immediately switches from automatic to manual emergency mode to avoid traffic interruption caused by equipment jamming.

[0050] When the drive unit 4 fails to drive the spool 24, the two single-pole double-throw switches 28 are switched, causing the drive shaft 14 to retract. The drive gear 18 no longer meshes with the drive gear 22, and the bevel gear 12 on the drive shaft 14 no longer meshes with the bevel gear 13. The manual lever is inserted into the spool 24 to drive it to rotate. The operator operates the single-pole double-throw switch 28, and the magnetic force of the electromagnetic coil 16 changes again, generating a repulsive force with the magnet 17. The drive shaft 14 extends, and the gears mesh, enabling power transmission.

[0051] As can be seen from the above specific embodiments, the present invention has the following beneficial effects: 1. By setting two sets of roller shutter doors 8 driven by vertical rollers 24 and horizontally unfolding and retracting along the upper and lower guide grooves 7 in the middle of the entrance and exit, not only can the door be opened and closed quickly to improve traffic efficiency, but also a clear separation of the entrance and exit channels is naturally formed when the door is retracted. This allows the gate component 1 2 and gate component 2 3 of the fence system to also integrate the function of diverting and guiding vehicles, effectively guiding vehicles to travel in one direction, avoiding oncoming traffic conflicts, reversing adjustments and traffic congestion, and significantly enhancing the safety and traffic order of the construction site entrance and exit. 2. A single drive motor 10 drives two roller shutter doors 8 to roll up and down, simplifying the structure while ensuring synchronous movement of the two roller shutter doors 8; 3. By setting the clutch sleeve 15 and clutch assembly 20, the door can be opened and closed manually when there is a power outage or when the drive motor 10 or transmission assembly 11 fails. In the event of a power outage, failure or special working conditions, the system can be quickly switched to manual operation without disassembling the transmission components, which improves the reliability, safety and maintenance convenience of the system. At the same time, the structure is compact and the positioning is accurate, ensuring that the gear meshing state is stable and reliable. 4. By using two single-pole double-throw switches 28, the direction of the magnetic poles of the electromagnetic coil 16 is controlled, thereby changing the direction of the force of the drive gear 18, ensuring smooth disconnection when the transmission is disconnected. During transmission, the limit plate 19 can limit the transmission shaft 14 to prevent its axial movement, ensuring the meshing of the drive gear 18 and the drive gear 22, and ensuring the synchronous movement of the two roller shutter doors 8. 5. By using the first rotating handle 1101 and the second rotating handle 1102, and the transition shaft 1105 for power transmission, the direction of force transmission is changed, so that the drive motor 10 can be installed horizontally on one side. Secondly, through the hinges and rotational connections at various points, the axial movement of the transmission shaft 14 can be disconnected from the transmission. 6. By setting up a cleaning shovel 27, the mud and other debris in the lower guide groove 7 can be cleaned as the roller shutter door 8 unfolds, ensuring the smooth opening of the roller shutter door 8; by setting up a detector to monitor the vehicle status within a set range in real time, and linking it with the indicator light strip 26, intuitive and hierarchical vehicle presence information feedback is achieved. The hierarchical prompts can give early warnings before the vehicle approaches the door, helping the driver to predict road conditions and adjust the driving route, reducing sudden lane changes, hard braking and reversing caused by blind spots or information asymmetry, thereby reducing the probability of conflicts at the door and traffic congestion.
