Description

Technical Field

[0001] This utility model relates to the field of access control equipment technology, specifically to a maintenance structure for the top of a rotating gate. Background Technology

[0002] Rotary gates, as efficient personnel access control devices, are widely used in places with extremely high security requirements. Their core function includes limiting the number of people passing through at one time.

[0003] However, existing rotating gates have significant drawbacks in maintenance and repair: in conventional setups, workers must climb to the top of the gate and disassemble the entire top cover to maintain the internal electrical modules. This process is not only time-consuming and labor-intensive but also carries the safety risks of working at height. Furthermore, the electrical components in traditional structures are scattered and disorganized, requiring individual inspection during maintenance, resulting in low maintenance efficiency. Although the industry's requirements for the reliability of rotating gates are increasing, current technology has not effectively resolved the issue of balancing maintenance convenience and operational safety. Therefore, a new structural solution that simplifies the maintenance process and reduces maintenance risks is urgently needed. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a top maintenance structure for a rotating gate. This maintenance structure improves maintenance efficiency and operational safety through modular layout and the setting of partial maintenance ports at the bottom.

[0005] To achieve the above and other related objectives, this utility model provides a maintenance structure for the top of a rotating gate, including a housing located at the top of the rotating gate, the housing comprising:

[0006] The top cover is detachably mounted on the top of the chassis;

[0007] At least one access port is located at the bottom of the chassis, and the access port is closed by a removable cover.

[0008] An electrical module is located inside the chassis and is configured corresponding to the maintenance port. The electrical module includes multiple electrical units; each electrical unit is at least one of a power supply unit, a control unit, a communication unit, a rotating gate mechanism, and a monitoring unit.

[0009] In one embodiment of the present invention, at least some electrical units within the electrical module are disposed on the inner edge of the inspection port and arranged along the circumferential direction of the inspection port.

[0010] In one embodiment of this utility model, the electrical module is provided in two sets, which are respectively located on both sides of the chassis, and the top cover covers the two sets of electrical modules.

[0011] In one embodiment of this utility model, at least some of the electrical units are detachably and independently installed via modular bases, and detachable electrical connection interfaces are provided between each of the modular bases.

[0012] In one embodiment of the present invention, each electrical module is provided with at least two access ports, and a transverse support structure is provided between the two access ports. The transverse support structure forms part of the reinforcing structure of the chassis.

[0013] The monitoring unit is installed on the side wall or top surface of the transverse support structure. The monitoring unit is at least one of a visual analysis module, an infrared sensor, or a laser scanning device, and the monitoring range covers the passage or operation area of ​​the rotating gate.

[0014] In one embodiment of this utility model, the multiple access ports on the chassis are arranged in a linear array along the length of the chassis, or in a ring array around the center of the chassis.

[0015] In one embodiment of this utility model, a sealing structure is provided at the joint between the cover and the inspection port, and the sealing structure includes at least one of a rubber gasket or a waterproof strip.

[0016] In one embodiment of the present invention, at least one of the electrical units in the electrical module is provided in two, and of the two electrical units with the same function, one is the main working unit and the other is the backup working unit.

[0017] In one embodiment of the present invention, the communication unit includes a data interface, the data interface being able to be plugged into at least a wired data cable, and the wired data cable being able to be led out of the chassis.

[0018] In one embodiment of this utility model, the opening size of the inspection port is adapted to the insertion of a part of the human body or a tool, and the inner wall of the inspection port is provided with a damage-proof protective layer.

[0019] In summary, this invention optimizes the maintenance method of traditional rotating gates through partial access ports and a modular electrical layout. When maintenance is required, workers only need to open the cover corresponding to the access port on the bottom of the chassis to directly operate on specific electrical units inside the chassis, without disassembling the entire top cover, fundamentally avoiding the risks of working at heights. The modular design integrates scattered electrical components into independent functional units, with each unit corresponding to an access port, significantly improving the efficiency of fault location and component replacement. Simultaneously, the detachable top cover maintains compatibility for large-scale maintenance. Attached Figure Description

[0028] Please see Figures 1 to 3 The present invention provides a top maintenance structure for a rotating gate 5, including a housing 10 located at the top of the rotating gate 5, the housing 10 including a top cover 1, a maintenance port 2 and an electrical module 4;

[0029] The top cover 1 is detachably disposed on the top of the chassis 10; at least one inspection port 2 is disposed on the bottom of the chassis 10, and the inspection port 2 is closed by a detachable cover door 3; the electrical module 4 is located inside the chassis 10 and is disposed corresponding to the inspection port 2, and the electrical module 4 includes multiple electrical units.

[0030] The electrical unit is at least one of the following: power supply unit 41, control unit 42, communication unit 43, rotating gate mechanism 44, and monitoring unit.

[0031] It should be noted that the top access structure of this rotating gate 5, through the optimized design of the chassis 10, achieves both convenience and safety in maintenance operations. The chassis 10 is located at the top of the rotating gate 5, and its top cover 1 adopts a detachable connection method, including but not limited to bolt fixing, snap locking, or sliding rail installation, to facilitate overall disassembly or partial maintenance. The bottom of the chassis 10 is provided with at least one access port 2, which is closed by a detachable cover 3. The opening and closing method of the cover 3 can be a hinged flip cover, a sliding door panel, or a magnetic panel, etc. The cover 3 can be made of transparent material, so that the internal structure of the chassis 10 can be observed before maintenance, making it easy for the maintenance personnel to open the corresponding cover 3, thus eliminating the need to remember the location of each electrical unit; the size of the access port 2 is adapted to the needs of human arms or tools to reach in for operation. The chassis 10 contains an electrical module 4 corresponding to the access port 2. The electrical module 4 includes multiple independent electrical units, such as at least one of a power supply unit 41, a control unit 42, a communication unit 43, a rotating gate mechanism 44, and a monitoring unit. The power supply unit 41 provides power to the other electrical units within the chassis 10. The control unit 42 controls the operation of the other electrical units within the chassis 10. The communication unit 43 facilitates data exchange and control between the various electrical units within the chassis 10, and / or enables communication or data transmission between the chassis 10 and the outside world. The rotating gate mechanism 44 controls the operation of the rotating gate 5. The monitoring unit monitors the area where the rotating gate 5 operates. It should be understood that the electrical units can also be other electrical components. Each electrical unit is mounted on a modular base, the type of which includes, but is not limited to, rail-mounted, plug-in, or screw-fixed bases. Units are interconnected through standardized interfaces, such as aviation plugs, spring terminals, or wireless communication modules, to achieve rapid assembly / disassembly and functional expansion.

[0032] The existing rotating gate 5 requires disassembly of its entire top cover 1 for maintenance, resulting in cumbersome procedures and a risk of falls from heights. Furthermore, the dispersed layout of electrical components leads to low troubleshooting efficiency. This solution effectively addresses these issues by combining a local access port 2 with modular electrical units. Specifically, in terms of operational safety, maintenance personnel no longer need to climb to the top of the chassis 10 or disassemble large structures; most maintenance operations can be completed through the bottom access port 2, significantly reducing the risk of working at heights. Regarding maintenance efficiency, the correspondence between the modular electrical units and access ports 2 allows for quick location and replacement of faulty units, significantly reducing troubleshooting time. It should be understood that one electrical unit can correspond to one access port 2, or one access port 2 can correspond to several electrical units. In terms of system reliability, each electrical unit is installed independently and does not interfere with others; a single point of failure is unlikely to affect overall operation. The modular layout also avoids short circuits or poor contact caused by messy cables. For locations with extremely high equipment reliability requirements, such as nuclear power plants and airports, its modular design can significantly reduce downtime caused by maintenance. For densely populated areas such as subway stations and office buildings, rapid maintenance capabilities can effectively reduce the risk of disruptions to passenger flow control. In addition, the maintenance structure in this case significantly reduces reliance on the skills of professional maintenance personnel; ordinary staff can complete routine operations after brief training, demonstrating broad prospects for industrial application.

[0033] Please see Figure 1 As an optional embodiment of this case, the chassis 10 is provided with a mounting frame 11, and at least one of the power supply unit 41, control unit 42, communication unit 43, rotating gate mechanism 44 and monitoring unit is disposed on the mounting frame 11.

[0034] Please see Figures 1 to 3 As an optional embodiment of this case, the rotating gate assembly includes a rotating gate 5, a protective railing 6 disposed on the side of the rotating gate 5, and a baffle 7 located on the side of the rotating gate 5. A passage for personnel to enter and exit is formed between the rotating gate 5 and the protective railing 6, and the chassis 10 is supported by the protective railing 6 and the baffle 7.

[0035] Please see Figures 1 to 2 As an optional embodiment of this case, two rotating gates 5 are provided. The two rotating gates 5 are close to each other and staggered to save space. The two rotating gates 5 and the two guardrails 6 form two channels. The two rotating gates 5 share a housing 10. The housing 10 is equipped with two sets of electrical modules 4. The two electrical modules 4 operate independently and control one of the corresponding rotating gates 5 respectively.

[0036] Please see Figure 1As an optional embodiment of this case, at least some of the electrical units in the electrical module 4 are disposed on the inner edge of the inspection port 2 and arranged along the circumferential direction of the inspection port 2.

[0037] It should be noted that the inner edge includes the inner wall, frame, or adjacent area of ​​the access port 2, and the electrical units can be arranged in a ring array, a fan-shaped distribution, or a symmetrical arrangement. In specific implementation, the electrical units can be installed on the mounting rails, slots, or brackets inside the access port 2. Their circumferential arrangement allows operators to access all relevant units without significant movement after opening the cover door 3. By concentrating the electrical units in the edge area of ​​the access port 2, this invention solves the problem of low maintenance efficiency caused by the dispersed internal components of the traditional rotating gate 5; maintenance personnel can complete the maintenance operations of multiple electrical units in a fixed position, significantly reducing operation time; the circumferential layout optimizes space utilization and avoids overcrowding inside the chassis 10.

[0038] Please see Figure 3 As an optional embodiment of this case, the electrical module 4 is provided in two sets, and the two sets of electrical modules 4 are respectively located on both sides of the chassis 10, and the top cover 1 covers the two sets of electrical modules 4.

[0039] It should be noted that the two sides can be the left and right symmetrical areas of the chassis 10, and the installation methods of the two sets of electrical modules 4 include, but are not limited to, mirror symmetrical layout, functional partition layout, or main-backup redundant layout. The top cover 1 can be an integrated cover, a split cover, or a folding cover to ensure comprehensive protection of the electrical modules 4 on both sides. In this case, the two electrical modules 4 can be set up as a redundant setting for a single rotating gate 5, or they can correspond to two rotating gates 5 respectively. When the two electrical modules 4 are set up redundantly, if any module fails, the backup module can automatically take over the function, thereby avoiding equipment downtime and solving the problem of equipment downtime caused by single system failure. The two sets of modules operate independently and serve as backups for each other. When one side of the module fails, the other side of the module can take over the function or maintain basic operation, thereby improving system reliability. During fault repair, the equipment can still maintain some functions. The partitioned isolation of the electrical modules 4 avoids mutual interference and reduces the risk of cascading failures. The integrated top cover 1 simplifies the external structure and reduces maintenance complexity.

[0040] Please see Figure 1 As an optional embodiment of this case, at least some of the electrical units are detachably and independently installed via modular bases, and detachable electrical connection interfaces are provided between each of the modular bases.

[0041] It should be noted that the modular base includes rail-mounted bases, plug-in bases, or screw-fixed bases, and the base material can be aluminum alloy, engineering plastic, or composite material. The types of detachable electrical connection interfaces cover aviation plugs, spring terminals, magnetic contacts, or wireless communication modules, with interface protection levels adapted to different environmental requirements. This invention solves the problem of insufficient maintenance flexibility caused by traditional fixed installations through modular bases and standardized interface settings. The modular base allows for quick assembly and disassembly of electrical units, while detachable interfaces ensure convenient and consistent electrical connections. This results in shorter maintenance time and improved efficiency in replacing electrical units; standardized interfaces reduce operational error rates and minimize faults caused by improper wiring; and independent installation of electrical units avoids impacting other units during maintenance, improving system availability.

[0042] Please see Figure 1 As an optional embodiment of this case, each electrical module 4 is provided with at least two access ports 2, and a transverse support structure 12 is provided between the two access ports 2. The transverse support structure 12 forms part of the reinforcing structure of the chassis 10.

[0043] The monitoring unit is installed on the side wall or top surface of the transverse support structure 12. The monitoring unit is at least one of a visual analysis module, an infrared sensor or a laser scanning device, and the monitoring range covers the passage or operation area of ​​the rotating gate 5.

[0044] It should be noted that the transverse support structure 12 may include an I-beam, box beam, or truss structure, and the material may be aluminum alloy, carbon steel, or composite material. Its connection to the chassis 10 may include welding, bolting, or snap-fitting. Monitoring units are installed on the side walls or top surface of the transverse support structure 12. These monitoring units may include visual analysis modules, infrared sensors, cameras, or laser scanning devices, and their monitoring range covers the passage or work area of ​​the rotating gate 5. The monitoring units may be equipped with angle adjustment mechanisms, such as universal joints or slide rails, to adapt to different detection angle requirements. Cable channels or heat dissipation holes may be integrated inside the transverse support structure 12 to optimize space utilization. This invention solves the problems of dispersed maintenance paths and insufficient structural strength in traditional systems by combining the transverse support structure 12 with the dual inspection ports 2. The lateral support structure 12 serves as both a rigid reinforcement component for the chassis 10 and a mounting base for the monitoring unit. The symmetrical layout of the dual access ports 2 allows maintenance personnel to operate simultaneously in adjacent areas, reducing travel distance and thus improving maintenance efficiency. The dual access ports 2 support parallel operation. The lateral support structure 12 enhances structural strength and avoids the risk of deformation caused by frequent disassembly. The optimized position of the monitoring unit ensures that the detection blind zone is minimized.

[0045] Please see Figure 1As an optional embodiment of this case, the plurality of inspection ports 2 on the chassis 10 are arranged in a linear array along the length of the chassis 10, or arranged in a ring array around the center of the chassis 10.

[0046] It should be noted that the linear array distribution includes equidistant, staggered, or gradually varying spacing arrangements, which are suitable for long and narrow chassis 10; the ring array distribution includes concentric circle, fan-shaped, or spiral arrangements, which are suitable for circular or polygonal chassis 10. Through standardized distribution patterns, the problem of chaotic maintenance paths caused by traditional random arrangements is solved, the logic and accessibility of maintenance operations are optimized, maintenance path planning efficiency is improved, and maintenance operation time is shortened.

[0047] Please see Figures 1 to 3 As an optional embodiment of this case, the junction of the cover 3 and the inspection port 2 is provided with a sealing structure, the sealing structure including at least one of a rubber gasket or a waterproof strip.

[0048] It should be noted that the rubber gasket can be an O-ring, a U-groove sealing strip, or a flat gasket, and the waterproof strip can be made of silicone or neoprene rubber. The sealing structure can be equipped with a self-tightening mechanism, such as a magnetic sealing strip or a pneumatic expansion sealing ring, to meet high-precision dustproof or waterproof requirements; a guide groove can also be provided at the joint to guide external liquids or dust away from the sealing surface.

[0049] This solution addresses the issue of internal contamination or water leakage caused by the incomplete closure of the traditional cover door 3 through optimized sealing structure design. The sealing structure uses elastic deformation to fill the microscopic gap between the cover door 3 and the inspection port 2, forming a physical barrier layer. This improves the cleanliness of the internal environment of the equipment, preventing dust or moisture from corroding electrical modules; extends the seal life, reducing frequent replacements due to aging; and adapts the protection level to different application scenarios, such as the high dustproof requirements of nuclear power plants or the moisture-proof needs of subway stations.

[0050] Please see Figure 1 As an optional embodiment of this case, at least one of the electrical units in the electrical module 4 is provided in two forms, and of the two electrical units with the same function, one is the main working unit and the other is the backup working unit.

[0051] It should be noted that the electrical unit generally includes any one of a power supply unit 41, a control unit 42, or a communication unit 43. The primary and backup working units can share the same modular base and be interconnected via a switching circuit, or they can be independently installed in areas corresponding to different maintenance ports 2, depending on the application scenario requirements. Status synchronization between the primary and backup working units can be achieved through heartbeat signals, data mirroring, or real-time verification mechanisms to ensure seamless switching in case of failure.

[0052] This solution addresses system downtime caused by single electrical unit failures through a primary / backup redundancy configuration. When the primary unit malfunctions, the backup unit automatically takes over or performs manual maintenance to switch functions, preventing service interruptions and significantly improving system availability. This extends the mean time between failures (MTBF) for critical functional units. During maintenance, the backup unit can maintain equipment operation, reducing downtime losses. The redundancy configuration is suitable for the reliability requirements of high-security environments, such as nuclear power plants or data centers.

[0053] As an optional embodiment of this case, the communication unit 43 includes a data interface, which can be plugged into at least by a wired data cable, and the wired data cable can be led out of the chassis 10.

[0054] It should be noted that the data interface types include, but are not limited to, RJ45 network ports, USB interfaces, or industrial bus interfaces. Wired data cables can be routed through waterproof connectors, elastic sealing sleeves, or guide grooves, or the data cable path can be laid along a pre-set cable tray within the chassis 10 or the hollow channel of the transverse support structure 12 to avoid external wear. This design, through standardized data interfaces and external connection settings, solves the problem of traditional rotating gate 5 relying on internal operations for communication maintenance. The external data interface allows maintenance personnel to perform remote debugging or data transmission without opening the inspection port 2, thereby improving maintenance flexibility and supporting rapid access to external devices; communication stability is improved, reducing poor contact caused by frequent plugging and unplugging; and the interface protection settings are adaptable to complex environments, such as high humidity or dusty scenes in subway stations.

[0055] As an optional embodiment of this case, the opening size of the inspection port 2 is adapted to the insertion of parts of the human body or tools, and the inner wall of the inspection port 2 is provided with a damage-proof protective layer.

[0056] It should be noted that the range of the opening size covers the space where an adult's arm can reach or the operating area of ​​a standard tool. The material of the protective layer includes, but is not limited to, rubber pads, polyurethane coatings, or insulating ceramic patches. The inner wall of the access port 2 may be equipped with guide rails or magnetic adsorption surfaces to assist in tool positioning or temporary placement of metal tools, such as temporary placement of screws to prevent screw loss. The surface of the protective layer may be set as a corrugated or honeycomb structure to enhance wear resistance.

[0057] This solution addresses the issue of tool collisions or electrostatic damage to electrical modules during maintenance by incorporating ergonomic dimensions and a protective layer. The ergonomic design reduces the range of motion required during operation, while the protective layer physically isolates the equipment, preventing scratches or short circuits caused by direct contact. This enhances the safety of maintenance operations and reduces the risk of injury to maintenance personnel. Furthermore, it extends the lifespan of internal components, minimizing hardware damage caused by misoperation. The insulating protective layer further protects against electrostatic discharge interference with precision circuits.

[0058] As an optional embodiment of this case, the electrical module 4 further includes a backup power supply unit 46, which is connected in parallel with the power supply unit 41.

[0059] As an optional embodiment of this case, the cover door 3 is fixed by a quick-locking assembly, which includes, but is not limited to, one of bolts, buckles or magnetic devices.

[0060] Please see Figure 1 As an optional embodiment of this case, the control unit 42 and the power supply unit 41 are installed on the same side, the monitoring unit is installed in the middle section of the transverse support structure 12, and the backup power supply unit 46, the communication unit 43, and the rotating gate mechanism 44 are installed on the other side. Meanwhile, the power supply unit 41, the backup power supply unit 46, the monitoring unit, the control unit 42, and the communication unit 43 are all highly integrated and modular, facilitating wiring, debugging, troubleshooting, maintenance, and repair. Furthermore, remote control can be achieved by extending a network cable from the communication unit 43.

[0061] Each access port 2 is equipped with a corresponding cover 3. Each access port 2 contains a different number of electrical units. The staff first removes the four corner bolts of the cover 3, opens the cover 3 corresponding to the access port 2 to expose the access port 2, and then stands in the passage or puts their head into the access port 2 to wire, debug, maintain, repair or troubleshoot the electrical modules, making the operation more convenient. After the maintenance is completed, the cover 3 can be installed back.

[0062] In summary, this utility model effectively overcomes some practical problems in the prior art, thus having high utilization value and significance.

[0063] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
