Description

Technical Field

[0001] This application relates to the field of substation cabinet technology, and in particular to a substation cabinet maintenance and protection marking device. Background Technology

[0002] In power system operation, substations and distribution rooms are equipped with numerous switchgear units for the conversion, control, and distribution of electrical energy. Because some equipment is energized while others are de-energized during maintenance or standby, on-site personnel who cannot accurately distinguish between energized and de-energized equipment are highly susceptible to accidental contact with energized equipment, leading to electric shocks or short circuits, severely impacting the safe and stable operation of the substation system. Therefore, clearly distinguishing and safely isolating energized equipment during de-energized maintenance or partial repairs of switchgear units is a crucial measure to ensure operational safety and reduce the risk of misoperation.

[0003] Currently, when inspecting live equipment or control cabinets, on-site personnel typically distinguish between live and de-energized equipment by hanging warning signs, affixing warning labels, or temporarily installing curtains or safety nets. While these methods provide some warning, the process is cumbersome and difficult to deploy quickly in environments with frequent maintenance or multiple control cabinets. Furthermore, although some roller blinds can achieve isolation, they often lack quick installation solutions tailored to the structure of control cabinets, requiring on-site modification or the addition of supports, which hinders their widespread use on standardized equipment. Summary of the Invention

[0004] To enable the rapid and reliable installation of isolation identification markers, this application provides a substation panel maintenance and protection identification device.

[0005] This application provides a substation panel maintenance and protection marking device, which adopts the following technical solution: A substation panel maintenance and protection marking device includes: A fixing component is installed on top of the substation panel cabinet and is used to fix the substation panel cabinet in place. A connecting component, which is detachably mounted on the fixing component; A shielding component, which is detachably mounted on the connecting component, is used to shield the substation panel cabinet.

[0006] By adopting the above technical solution, and using a layered combination structure of fixed components, connecting components and shielding components, not only can the roller shutter protective identification device be quickly installed and securely connected on the substation panel cabinet, but it also takes into account the dual functions of protection and isolation and live identification, effectively reducing the occurrence of personal and equipment damage caused by accidental contact with live equipment during maintenance.

[0007] Optionally, the fixing component includes a first connector, a second connector, and a fastener. The first connector and the second connector are connected above each other by the fastener. A clamping space is formed between the first connector and the second connector. The first connector and the second connector are used to clamp the top of the substation cabinet.

[0008] By adopting the above technical solution, the mechanical clamping can be achieved directly using the top edge of the cabinet through the clamping cooperation of the first and second connectors. Moreover, the clamping space can be flexibly adjusted according to the tightness of the fasteners, thus adapting to cabinet top panels of different thicknesses or types, and has good compatibility and adaptability. At the same time, the fasteners can provide stable clamping force after being locked, preventing the protective device from loosening or shifting during use, and ensuring long-term safety and reliability.

[0009] Optionally, the first connector includes a horizontal part and a vertical part, the horizontal part is disposed at the upper end of the vertical part, the horizontal part is used to fit the upper surface of the substation cabinet, and the vertical part is used to fit the front of the substation cabinet; A first connecting part is provided above the horizontal part, and a second connecting part is provided above the second connecting part. The first connecting part and the second connecting part are connected by the fastener.

[0010] By adopting the above technical solution, a horizontal part and a vertical part are set up so that the first connecting member forms an "inverted L-shaped" structure. The horizontal part can fit with the upper surface of the substation cabinet, and the vertical part can fit with the front of the cabinet, thereby forming support in two orthogonal directions. This significantly improves the contact stability and anti-slip ability between the device and the cabinet, and prevents the device from loosening or falling off due to vibration or external force.

[0011] Optionally, both the first connecting part and the second connecting part are hollow positioning posts, and the fastener is a bolt, which passes through the two hollow positioning posts.

[0012] By adopting the above technical solution, both the first and second connecting parts are designed as hollow positioning columns, and the bolts can be inserted along the hollow structure, so that the two can achieve precise coaxial positioning during the assembly process, ensuring that the fixed components will not be skewed or misaligned when tightened, thereby improving the overall installation accuracy and stability.

[0013] Optionally, the end face of the vertical section near the substation cabinet is provided with an adhesive piece for bonding and fixing, and the adhesive piece is detachably installed on the vertical section. By adopting the above technical solution, an adhesive component is set on the vertical part near the end face of the cabinet, which provides additional adhesive force on the basis of clamping and fixing, so that the fixing component and the surface of the cabinet form a double fixing effect, avoiding the device from loosening or displacement due to vibration or external force, thereby improving the stability and reliability of the overall installation.

[0014] Optionally, the vertical part is provided with a waist-shaped hole, the waist-shaped hole is provided in the vertical direction, the connecting component is slidably disposed in the waist-shaped hole, and the connecting component is fixed in the waist-shaped hole by fastening bolts.

[0015] By adopting the above technical solution, a waist-shaped hole extending vertically is provided on the vertical part, so that the connecting component can slide up and down in the hole, thereby flexibly adjusting the installation position according to the height of different substation cabinets or the need for roller shutter obstruction.

[0016] Optionally, the shielding assembly includes a mounting housing, a rotating shaft, and a roller blind, wherein the rotating shaft is rotatably disposed within the mounting housing in a horizontal axis. One end of the roller blind is fixedly connected to the rotating shaft, and the other end of the roller blind is provided with an operating component, which is used to unfold and retract the roller blind.

[0017] By adopting the above technical solution, using a rotating shaft drive in conjunction with the operating components, the roller shutter can be quickly raised and lowered, securely shielded, and space-saving, effectively improving the safety and on-site operation convenience of the cabinet maintenance work.

[0018] Optionally, the operating component includes a connecting rod and a pull ring, the roller blind is fixedly connected to the connecting rod, and the pull ring is detachably mounted on the connecting rod.

[0019] By adopting the above technical solution, the roller shutter is fixed by a connecting rod, and operators can easily pull or retract the roller shutter using the pull ring to quickly shield the energized or de-energized area in front of the control cabinet. The operation is simple and requires little labor. Moreover, the detachable design of the pull ring allows for maintaining a certain distance during operation, preventing personnel from directly touching the edge of the roller shutter or approaching live parts, reducing the risk of electric shock or injury, and meeting the safety operation requirements of substations.

[0020] Optionally, the device further includes a controller, a vibration sensor, an audible and visual alarm, and a power module; The vibration sensor is mounted on the rotating shaft; Both the controller and the power module are housed within the mounting housing; The audible and visual alarm is mounted on the outer surface of the mounting housing. The controller is connected to the vibration sensor, the audible and visual alarm, and the power module respectively. When the vibration sensor detects a vibration signal, the controller activates the audible and visual alarm.

[0021] By adopting the above technical solution, vibration detection is combined with audible and visual alarms to achieve a dual safety mechanism of passive shielding and active reminders. This allows the device to not only provide physical protection but also have an intelligent prompting function when raising and lowering the roller shutter, thereby improving the level of on-site management and operational efficiency of the substation.

[0022] Optionally, the device further includes a Bluetooth module and a remote control center; The controller is connected to the remote control center via a Bluetooth module. The Bluetooth module is housed inside the mounting housing; When the audible and visual alarm sounds, the controller sends an alarm signal to the remote control center via Bluetooth.

[0023] By adopting the above technical solution, the controller connects to the remote control center via Bluetooth module, realizing remote alarm and real-time information transmission for the operation of the roller shutter, further improving on-site safety, management efficiency, and intelligence level.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The fixing assembly, through the cooperation of the first connector, the second connector, and fasteners, achieves a stable clamping of the top of the substation cabinet. Simultaneously, the clamping space formed between the first and second connectors accommodates cabinet top plates of varying thicknesses, achieving reliable fixing without requiring drilling or modification of the cabinet. Furthermore, the horizontal and vertical portions of the first connector respectively conform to the upper and front surfaces of the cabinet, providing multi-directional support and significantly improving the overall structural stability of the device. This prevents loosening or detachment under external forces or vibrations, thereby enhancing installation reliability and operational safety.

[0025] 2. The connecting component adopts a detachable installation structure and works in conjunction with the oblong hole on the vertical part. The vertical extension structure of the oblong hole allows the connecting component to be height-adjusted within a certain range, thus adapting to different models or sizes of cabinets. This facilitates precise positioning during installation and ensures stability and prevents displacement after tightening the bolts, guaranteeing the shielding effect and long-term reliability of the protective markings. Furthermore, the detachable design of the connecting component allows for quick assembly and disassembly during maintenance, repair, or replacement, improving ease of use and reusability.

[0026] 3. In this application, the shielding component consists of a mounting housing, a rotating shaft, and a roller shutter. The roller shutter is raised and lowered by horizontal rotation of the rotating shaft. The roller shutter can be unfolded to shield the live electrical panel when needed and quickly retracted into the mounting housing after maintenance. Operation is simple and efficient. Compared to traditional fabric curtain protection, this structure occupies less space, does not affect the panel door or ventilation structure, and is reusable, reducing maintenance costs. Furthermore, through modular design, the shielding component can be quickly installed or replaced, adapting to different substation environments and achieving both protective and warning functions, significantly improving the safety level of on-site operations.

[0027] 4. The alarm and remote monitoring module works collaboratively with the controller, vibration sensor, audible and visual alarm, and Bluetooth module. When the vibration sensor detects an abnormal vibration signal, the controller can immediately activate the audible and visual alarm to provide timely alerts for on-site intrusion or accidental activation. Simultaneously, the controller sends alarm signals to the remote control center via the Bluetooth module, enabling management personnel to receive alarm information in real time, forming a dual protection system of local alarm and remote monitoring. This design effectively improves the intelligence and safety protection level of the device, meeting the needs of substation operation sites for real-time monitoring and safety management.

[0030] It should be understood that all descriptions are given for illustrative purposes only and should not be construed as limiting the present invention in any way. In this document, the technical terms "first" and "second" are used only for distinguishing purposes and are not intended to indicate their order or relative importance. The technical term "connection (or linking, etc.)" covers a specific component being directly connected to another component and / or indirectly connected to another component. Furthermore, unless otherwise expressly specified and limited, the dimensions, directions, or positional relationships indicated by technical terms such as "length," "width," "height," "upper," "top," and "bottom" are based on the dimensions, orientations, or positional relationships shown in the accompanying drawings and are only for the convenience and simplification of the description of the present invention, and should not be construed as limiting the present invention.

[0031] The following combination Figures 1 to 10 The present invention will be described in further detail below.

[0032] Example 1: This example discloses a substation panel maintenance and protection marking device, referring to... Figure 1 The device includes a fixing component, a connecting component, and a shielding component. The fixing component is installed above the substation panel cabinet for secure connection. The connecting component is detachably installed on the fixing component. The shielding component is detachably installed on the connecting component for shielding the substation panel cabinet. This application, through the combined design of the fixing and connecting components, achieves rapid and stable installation of the substation panel cabinet maintenance and protection marking device. This not only simplifies the on-site operation process but also facilitates installation and disassembly by a single person, greatly improving the device's portability and reusability. It should be noted that... Figure 1 The diagram only illustrates the positional installation relationship of the fixing component, connecting component, and shielding component. Those skilled in the art can select the type of connecting component according to installation needs.

[0033] In this embodiment, the fixing assembly includes a first connector 1, a second connector 2, and a fastener. The first connector 1 includes a horizontal portion and a vertical portion, with the horizontal portion positioned at the upper end of the vertical portion and forming an inverted L-shape, such as... Figure 2 and Figure 3As shown. During use, the horizontal part is used to fit against the upper surface of the substation cabinet, and the vertical part is used to fit against the front of the substation cabinet. The "inverted L-shaped" structure achieves stable clamping support without damaging the original structure of the cabinet, allowing the entire protective marking device to be quickly and reliably fixed to the top of the cabinet. It has the advantages of convenient installation and a stable structure.

[0034] like Figure 4 and Figure 5 As shown, a first connecting part 3 is provided above the horizontal part, and a second connecting part 4 is provided above the second connecting part 2. The first connecting part 1 and the second connecting part 2 can be connected by fasteners, so that a clamping space is formed between the first connecting part 1 and the second connecting part 2 for clamping on the top of the substation cabinet. It can be flexibly adjusted according to the thickness of different substation cabinets, has a wide range of applications, and has good versatility.

[0035] like Figure 6 As shown, in this embodiment, both the first connecting part 3 and the second connecting part 4 are hollow positioning posts, and bolts can be used as fasteners. During use, the bolts are inserted into the two hollow positioning posts, and the width is adjusted according to the different models of the cabinet. Tightening achieves positioning and clamping. This design not only simplifies the installation operation but also automatically limits the assembly position through the hollow positioning posts, avoiding tilted or misaligned installation, thereby improving the overall installation stability and repeatability accuracy. Furthermore, the self-limiting fit structure of the hollow positioning posts allows for automatic centering and clamping without additional calibration, greatly shortening installation time and improving the universal compatibility between different specifications of cabinets. In other embodiments, fasteners can be screws, quick-locking devices, or elastic clamping rods.

[0036] An adhesive strip is provided on the end face of the vertical section near the substation cabinet for auxiliary bonding and fixing. The adhesive strip can be detachably installed on the vertical section. This adhesive strip can use 3M industrial-grade double-sided tape, weather-resistant silicone pads, or other bonding structures. Depending on the operating environment, high-temperature resistant, moisture-resistant, or anti-aging materials can be selected. This structure maintains firmness while providing good detachability without damaging the cabinet surface.

[0037] The vertical section also features a slotted hole 5 extending vertically. The connecting component is slidably positioned within the slotted hole 5, allowing it to slide vertically. During use, the connecting component can be secured to the desired height using fastening bolts.

[0038] like Figure 7As shown, in this embodiment, the connecting component preferably adopts a snap-fit ​​structure, including an elastic latch 9 and an adjustment hole 10. In use, according to the height to be set, bolts are inserted into the adjustment hole 10 and the slotted hole 5, and positioning and clamping are achieved by tightening. Then, the elastic latch 9 is used to fix the shielding component to achieve quick assembly and disassembly. The user only needs one hand to complete the fixing or releasing operation, which significantly improves the efficiency of on-site deployment.

[0039] To further improve installation convenience and stability, such as Figure 8 As shown, in this embodiment, a bolt-supported adhesive component is preferably used. The bolts can be inserted into the mounting hole 11 and the slotted hole 5 to achieve a secure connection between the adhesive component and the fixing assembly. Specifically, as shown... Figure 9 As shown, during use, bolts are inserted into the mounting hole 11, the waist-shaped hole 5, and the adjustment hole 10, thereby simultaneously achieving mechanical locking and adhesive-assisted fixation, forming a dual positioning method that ensures the connection components remain stable under vibration or frequent operation.

[0040] It should be noted that in this embodiment, both the fixing components and the connecting components are made of insulating materials, such as epoxy resin, polycarbonate, polyamide and other engineering plastics, to prevent leakage or short circuit in a live environment, thereby ensuring the safety of the operators.

[0041] In practical applications, the protective marking device described in this application can be quickly installed on top of the cabinet using a single fixing component. However, to enhance structural stability and prevent the roller shutter 8 from swaying or tilting, two or more fixing components can be installed as needed. Preferably, a two-fixing-component structure is used, installed on both sides of the substation cabinet door. During use, the distance between the two fixing components can be determined based on the width of the cabinet door and the length of the roller shutter 8 before installation to ensure optimal tension and shielding effect of the roller shutter 8 after unfolding, resulting in a more robust and reliable protective state.

[0042] The blinding assembly includes a mounting housing 6, a rotating shaft 7, and a roller blind 8. The rotating shaft 7 is horizontally rotatable within the mounting housing 6. One end of the roller blind 8 is fixedly connected to the rotating shaft 7, and the other end of the roller blind 8 is equipped with an operating component for opening and closing the roller blind 8. The structure is simple and intuitive to use. The roller blind 8 can be made of flame-retardant insulating canvas, PVC insulating film, or fiberglass reinforced protective fabric, and features good flexibility, high voltage resistance, and dust and splash protection.

[0043] Preferably, the roller shutter 8 is made of a conspicuous red insulating fabric, and warning signs such as "Operating Equipment," "Do Not Operate," and "Under Maintenance" are printed on its surface. The content of these signs can be changed or customized according to actual needs. This design not only provides physical protection but also serves as a significant visual safety warning, effectively preventing accidental operation or contact with electrical equipment. This "protection + warning integrated" structure provides dual safety benefits, significantly improving the practicality and safety management efficiency of the device while simplifying its structure.

[0044] In this embodiment, the operating components include a connecting rod and a pull ring. The roller shutter 8 is fixedly connected to the connecting rod, and the pull ring is detachably mounted on the connecting rod, preferably using a snap-fit ​​connection structure. Operators can easily unfold and retract the roller shutter 8 using the pull ring without any additional tools, making operation convenient and quick. To ensure operator safety in live environments, both the pull ring and the connecting rod are made of insulating material.

[0045] In practical use, the operator first adjusts the height of the connecting component through the waist-shaped hole 5 as needed and locks it with the fastening bolts. Then, the adhesive part of the vertical part of the first connecting piece 1 is attached to the front edge of the substation cabinet. Next, the distance between the first connecting piece 1 and the second connecting piece 2 is adjusted according to the width of the top surface of the cabinet. The bolts are then tightened through the hollow positioning posts on both sides until they are firmly clamped. After installation, the operator can pull the ring of the roller shutter 8 to unfold the shielding cloth, so that the cabinet is completely covered. After the operation is completed, the ring is released, and the roller shutter 8 automatically retracts into the mounting shell 6.

[0046] This application features a compact and highly modular design, offering significant advantages such as convenient installation, tool-free operation, reusability, portability, strong compatibility, and high insulation safety. In particular, the triple fixing method—combining clamping, adhesive attachment, and adjustable slotted holes—achieves an unexpectedly efficient and rapid fixation without any modifications to the substation cabinet. Furthermore, it can be stably used on various specifications and models of substation cabinets, significantly improving the efficiency of on-site protection deployment and safety management.

[0047] Example 2: Unlike Example 1, the device further includes a controller 12, a vibration sensor 13, an audible and visual alarm 14, and a power module 15, as follows: Figure 10 As shown.

[0048] Vibration sensor 13 is mounted on the rotating shaft 7 to monitor the vibration status of the rotating shaft 7 and the roller shutter 8 in real time. When the roller shutter 8 is touched, pulled, or vibrated by an external force, vibration sensor 13 can immediately output an electrical signal.

[0049] Both the controller 12 and the power module 15 are housed in the mounting housing 6. The power module 15 provides stable power to the controller 12, and the controller 12 is used to receive signals from the vibration sensor 13.

[0050] The audible and visual alarm 14 is installed on the outer surface of the mounting housing 6, preferably in a conspicuous position on the front or side of the device, so that when triggered, it can achieve a significant on-site warning effect through flashing lights and high-frequency buzzing.

[0051] The controller 12 is connected to the vibration sensor 13, the audible and visual alarm 14, and the power module 15. When the vibration sensor 13 detects a vibration signal, the controller 12 controls the audible and visual alarm 14 to sound an alarm, alerting on-site personnel that the cabinet is currently powered on or in a state awaiting maintenance.

[0052] Furthermore, the device also includes a Bluetooth module 16 and a remote control center 17. The Bluetooth module 16 is housed within the mounting housing 6 and is connected to the controller 12 via Bluetooth 16, enabling wireless communication between the controller 12 and the remote control center 17. When the audible and visual alarm 14 sounds, the controller 12 sends an alarm signal to the remote control center 17 via Bluetooth 16. The remote control center 17 can display the alarm time and device number in real time, facilitating rapid response and on-site handling by maintenance personnel. Additionally, staff can statistically analyze the number of alarms and their duration, providing data support for equipment maintenance and operational status assessment.

[0053] This application sets up a combination of vibration sensors and controllers to monitor the status of the roller shutter and protective devices in real time. When abnormal vibration is detected, an audible and visual alarm is triggered immediately, effectively avoiding the potential risks caused by staff accidentally touching the live electrical cabinet or equipment vibration.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
