Description

Technical Field

[0001] This utility model relates to the field of cabinet technology, specifically to an unattended cabinet external monitoring rack and cabinet. Background Technology

[0002] In many industries such as telecommunications and power, the stable operation of base station cabinets is crucial to the normal functioning of the entire system. Currently, the daily operation and maintenance of base station cabinets mainly rely on manual labor. Tasks such as starting and stopping equipment, adjusting and setting parameters, troubleshooting and handling faults, and regular inspections and maintenance all require the hands-on involvement of professional personnel.

[0003] However, in areas with harsh geographical environments and extremely inconvenient transportation, such as uninhabited plateaus, remote mountainous areas, and isolated islands at sea, as well as high-risk environments such as chemical industrial parks and nuclear power plants, the drawbacks of traditional manual maintenance methods become apparent. Conducting routine inspections in these special areas leads to a sharp increase in labor costs. Taking remote mountainous areas as an example, maintenance personnel often need to travel long distances, incurring high transportation costs, and due to environmental limitations, work efficiency is significantly reduced, further increasing labor costs.

[0004] More seriously, the health and safety of personnel working in these extreme environments face enormous threats. In uninhabited high-altitude areas, the low-oxygen environment can easily trigger altitude sickness, endangering personnel's health; chemical industrial parks pose a risk of toxic chemical leaks; and the vicinity of nuclear power plants carries radiation hazards. Utility Model Content

[0005] The purpose of this utility model is to provide an external monitoring frame and cabinet for unattended cabinets. By sliding the monitoring mechanism, which consists of a first adjustment component, a second adjustment component, and a monitoring component, along the cabinet connecting rod to form a multi-dimensional adjustable modular structure, the position of the camera can be flexibly adjusted in space. This enables monitoring, convenient operation, and specification adaptation of the cabinet display screen and other auxiliary equipment. It solves the problems of high manual maintenance costs and high personnel safety risks in base station cabinets in high-altitude uninhabited areas, remote areas, and high-risk environments.

[0006] This utility model is achieved through the following technical solution:

[0007] An unattended external monitoring rack for server racks includes:

[0008] Rack connecting rods, wherein the rack connecting rods are arranged in pairs and respectively connected to both sides of the rack;

[0009] The first adjustment component is arranged in pairs and connected to the cabinet connecting rods on both sides respectively. The end of the first adjustment component is provided with a first slider, and the cabinet connecting rod is provided with a first adjustment groove that matches the first slider, so that the first adjustment component can move along the height direction of the cabinet.

[0010] The second adjustment component has one end rotatably connected to the free end of one of the first adjustment components via a rotating part, and the other end of the second adjustment component is movably connected to the free end of the other first adjustment component via a connecting part.

[0011] A monitoring component is connected to the second adjustment component and faces the surface of the cabinet to be monitored.

[0012] In this solution, paired rack connecting rods serve as the mounting base, fixed to both sides of the rack's monitored surface. The first adjustment component, through the cooperation of a first slider and a first adjustment groove, achieves sliding adjustment along the rack's height, meeting longitudinal position adaptation requirements. The second adjustment component is rotatably connected to one side of the first adjustment component via a rotating part and movably connected to the other side via a connecting part, forming a movable lateral linkage structure. This supports angle adjustment of the monitoring rack for quick removal or reset. The monitoring component is connected to the second adjustment component and faces the monitored surface. Stable monitoring of the rack's status is achieved through the coordinated adjustment of the overall structure. This solution, through multi-dimensional adjustable modular connections, solves the high cost and high risk issues of manual inspection in extreme environments, enabling remote monitoring, convenient operation, and specification adaptation of the rack.

[0013] As a further solution for the external monitoring frame, one end of the first adjustment component is connected to the second adjustment component via a movable hinge.

[0014] In this design, the movable hinge acts as a rotating connection component, allowing the second adjustment component to undergo a resettable angular change relative to the first adjustment component. This ensures the monitoring rack maintains a stable camera view during normal monitoring, while allowing the rack to be quickly moved away by rotating the second adjustment component when the cabinet needs operation (such as equipment maintenance or parameter adjustment), avoiding obstruction of the cabinet's operating space. This connection method guarantees structural stability during monitoring and meets the convenience requirements of maintenance operations (quick relocation without disassembly). Furthermore, the hinge's resettable nature solves the problems of traditional fixed monitoring racks obstructing the control panel or requiring repeated camera position adjustments, achieving compatibility between monitoring functions and cabinet operations.

[0015] As a further solution for the external monitoring frame, the monitoring components include an adjustable forearm and a camera mounting clip;

[0016] One end of the adjustable arm is connected to the second adjustment component, and a third adjustment groove is provided on the adjustable arm along its own length direction. One end of the camera fixing clamp is provided with a fourth slider that matches the third adjustment groove, so that the camera fixing clamp can move along the length direction of the adjustable arm.

[0017] In this solution, the adjustable arm serves as an intermediate component connecting the second adjustment assembly and the camera mounting clip. One end is fixedly connected to the second adjustment assembly, while the other end has a third adjustment groove along its length, providing a sliding track for the camera mounting clip. The camera mounting clip is embedded in the groove via a fourth slider that matches the third adjustment groove, allowing it to move freely along the length of the adjustable arm. This enables adjustment of the camera's position in the horizontal dimension (closer or farther from the monitored surface of the cabinet). In actual operation, operators precisely adjust the distance between the camera and the monitored surface of the cabinet by sliding the camera mounting clip according to actual monitoring needs, achieving fine-tuning of the focus and ensuring the clarity and integrity of the monitored image.

[0018] As a further embodiment of the external monitoring frame, one end of the second adjustment component away from the movable hinge is connected to the first adjustment component on the other side via a corner slot connector.

[0019] In this design, the corner slot connector serves as a movable connecting component, connecting the end of the second adjustment component furthest from the movable hinge to the first adjustment component on the other side. While ensuring a rigid overall structure between the first and second adjustment components on both sides, it allows the second adjustment component to rotate angularly around the movable hinge. This ensures the structural stability of the monitoring rack under normal monitoring conditions through the built-in set screw locking function of the corner slot connector (preventing loosening or displacement due to vibration or external force), and also enables the opening and closing of the monitoring rack through its cooperation with the movable hinge. When the rack needs to be operated, the second adjustment component is rotated around the movable hinge, and the corner slot connector moves synchronously with the second adjustment component, allowing the entire monitoring rack to be quickly moved out of the operating space without disassembling any components. After the operation is completed, the second adjustment component is rotated in the opposite direction, and the corner slot connector resets along a preset trajectory, ensuring the camera accurately returns to its original monitoring view.

[0020] As a further embodiment of the external monitoring rack, the second adjustment component includes a crossbar with a second adjustment groove, and one end of the monitoring component is provided with a third slider that matches the second adjustment groove, so that the monitoring component can move along the width direction of the rack.

[0021] In this solution, the second adjustment groove on the surface of the crossbar provides a sliding track for the monitoring component along the width direction (lateral direction) of the cabinet. The third slider is embedded in the adjustment groove and fixedly connected to the monitoring component, allowing the monitoring component to move freely on the crossbar according to actual monitoring needs. Operators can precisely adjust the lateral position of the monitoring component according to the width of the cabinet to be monitored, the spacing between multiple cameras, or a specific monitoring angle. For example, the camera can be aimed at the center area of ​​the display screen or the indicator lights on both sides, or multiple monitoring components can be installed on the same crossbar to achieve multi-angle coverage.

[0022] As a further solution for the external monitoring rack, a second slider matching the second adjustment slot is connected to one end of the corner slot connector away from the first adjustment component, so that the corner slot connector can move along the width direction of the cabinet.

[0023] In this solution, the end of the corner slot connector away from the first adjustment component is matched and connected to the second adjustment slot of the second adjustment component through the second slider, so that the corner slot connector can slide along the width direction (lateral direction) of the cabinet. This allows the monitoring rack to flexibly adjust the lateral spacing of the first adjustment components on both sides according to the cabinet width or monitoring angle requirements, such as to adapt to cabinets of different widths or to accurately align with the edge area of ​​the display screen.

[0024] As a further embodiment of the external monitoring frame, the monitoring component includes an adjustable arm and a camera fixing clip. The third slider is connected to one end of the adjustable arm, and the adjustable arm has a third adjustment groove along its own length direction. One end of the camera fixing clip is provided with a fourth slider that matches the third adjustment groove, so that the camera fixing clip can move along the length direction of the adjustable arm.

[0025] In this solution, one end of the adjustable arm is connected to the second adjustment slot of the second adjustment component via a third slider, achieving initial positioning of the monitoring component in the width direction of the cabinet. The third adjustment slot, which is opened along its length, provides a longitudinal (closer to or farther from the monitoring surface of the cabinet) sliding track for the camera clamp. The camera clamp is embedded in the third adjustment slot via a matching fourth slider and can move freely along the length of the adjustable arm, thereby adjusting the distance between the camera and the monitoring surface of the cabinet. By sliding the camera clamp to control the longitudinal position of the camera, and in conjunction with the lateral adjustment of the third slider on the crossbar, a position calibration in a two-dimensional plane is formed to ensure that the monitoring image completely covers the target area.

[0026] As a further solution for the external monitoring frame, the first adjustment component includes a first adjustable arm and a second adjustable arm. One end of the first adjustable arm is connected to the cabinet connecting rod on one side via the first slider. The other end of the first adjustable arm has a fourth adjustment slot. The end of the second adjustable arm is provided with an adjustment rod that matches the fourth adjustment slot, so that the second adjustable arm can move relative to the first adjustable arm.

[0027] In this solution, the first adjustable arm is slidably connected to the first adjustment groove of the cabinet connecting rod via the first slider, thereby achieving the initial positioning of the entire component along the height direction of the cabinet. The fourth adjustment groove at its other end provides a sliding track for the adjustment rod of the second adjustable arm, allowing the second adjustable arm to extend and retract along the length direction of the first adjustable arm, thereby dynamically adjusting the overall longitudinal length of the first adjustment component.

[0028] As a further solution for the external monitoring frame, the first adjustment assembly also includes a third adjustment arm and a fourth adjustment arm. One end of the third adjustment arm is connected to the cabinet connecting rod on the other side via the first slider. The other end of the third adjustment arm has a fourth adjustment slot. The end of the fourth adjustment arm is provided with an adjustment rod that matches the fourth adjustment slot, so that the fourth adjustment arm can move relative to the third adjustment arm.

[0029] In this design, the third adjustable arm is slidably connected to the first adjusting groove of the connecting rod on the other side of the cabinet via a first slider, achieving initial positioning of the component along the cabinet height. The fourth adjusting groove at its other end slides into the adjusting rod at the end of the fourth adjustable arm, allowing the fourth adjustable arm to extend and retract relative to the third adjustable arm, thereby dynamically adjusting the longitudinal length of the first adjusting component on that side. This design, through its symmetrical double-sided design, allows for synchronous or independent adjustment of the left and right adjustable arms, adapting to different cabinet heights and installation positions of the monitored surfaces. Furthermore, the coordinated extension and retraction of the double-sided structure maintains the overall balance and stability of the monitoring frame.

[0030] A cabinet, wherein an unattended external monitoring frame as described above is connected to both sides of the cabinet, wherein a monitoring mechanism consisting of the first adjustment component, the second adjustment component and the monitoring component is arranged in multiple sets at intervals along the cabinet connecting rod.

[0031] In this solution, each monitoring unit can be independently adjusted along the height of the cabinet by sliding the first adjustment component. Combined with the lateral position adjustment and angle rotation functions of the second adjustment component, it can achieve precise monitoring of different heights and viewing angles of the cabinet. The spaced arrangement of multiple units supports distributed monitoring coverage of large cabinets or multi-layer equipment, avoiding blind spots of a single monitoring component. It is especially suitable for cabinet scenarios with multiple displays or complex equipment layouts.

[0032] In summary, compared with the prior art, this utility model has the following main advantages and beneficial effects:

[0033] 1. In areas with harsh geographical environments and extremely inconvenient transportation, such as uninhabited plateaus, remote mountainous areas, and isolated islands at sea, as well as high-risk environments such as chemical industrial parks and nuclear power plants, traditional manual maintenance methods are costly and dangerous. This utility model's external monitoring frame, in conjunction with monitoring components, enables remote monitoring, reducing the frequency of on-site manual maintenance, lowering labor costs, and ensuring the safety of maintenance personnel.

[0034] 2. This utility model, by setting a first adjustment component, has a first slider at its end that cooperates with a first adjustment groove on the cabinet connecting rod, allowing it to move along the height direction of the cabinet; and the adjustment arms within the first adjustment component can move relative to each other via an adjustment rod and a fourth adjustment groove, allowing for flexible adjustment of the longitudinal position and distance of the monitoring component; the second adjustment groove on the crossbar of the second adjustment component, in cooperation with the third slider of the monitoring component and the second slider on the corner slot connector, enables the monitoring component and the corner slot connector to move along the width direction of the cabinet; and the third adjustment groove on the adjustment arm of the monitoring component, in cooperation with the fourth slider of the camera fixing clamp, allows for adjustment of the camera position along the length direction of the adjustment arm. These multi-dimensional adjustment functions can meet the diverse needs of different cabinet specifications and different monitoring scenarios for monitoring angles and ranges, making it more adaptable than traditional fixed-structure monitoring racks.

[0035] 3. The first adjustment component and the second adjustment component of this utility model are connected by a movable hinge, allowing the second adjustment component to rotate. When it is necessary to operate the cabinet, the second adjustment component can be rotated open to quickly move the monitoring component away, avoiding obstruction of the cabinet's operating space. After the operation is completed, it can be rotated back to its original position to ensure that the monitoring angle remains unchanged. This facilitates the daily operation and maintenance of the cabinet, solves the problem of frequent disassembly required when operating the cabinet with traditional monitoring racks, and improves work efficiency.

[0036] 4. The cabinet of this utility model can be connected to multiple monitoring mechanisms consisting of a first adjustment component, a second adjustment component, and a monitoring component. These monitoring mechanisms are arranged at intervals along the cabinet connecting rods, enabling all-round monitoring of different parts of the cabinet and avoiding blind spots. Compared with a single monitoring frame, the monitoring range is wider and more comprehensive, and the cabinet's operating status information can be obtained more timely and accurately.
