Description

Technical Field

[0001] This utility model relates to the field of low-voltage switchgear technology, and in particular to a switchgear with video monitoring function. Background Technology

[0002] A switchgear is a complete set of electrical equipment used in the high and low voltage power distribution links of a power system. It has a metal cabinet as its outer shell and integrates core components such as circuit breakers, contactors, relays, disconnect switches, measuring instruments, and protection devices. Its main function is to receive, distribute, control, and protect electrical energy.

[0003] Currently, in actual use, switchgear is equipped with multiple cameras to detect the mechanical actions of circuit breakers and grounding switches. This allows for timely detection of the status of circuit breakers during the switching process and the mechanical status of grounding switches during opening and closing, enabling immediate and intuitive identification of problems and reducing the potential for deterioration in electrical performance, thus facilitating timely replacement and maintenance.

[0004] The existing camera is fixedly installed inside the switch cabinet using a metal bracket. The bracket is connected to the structural components of the switch cabinet with screws to ensure a stable installation. The metal mounting bracket uses a double screw and nut fastening method. The two screws pass through both sides of the bracket, and the nuts are tightened between the bracket and the switch cabinet structural components to ensure a firm connection to the camera and allow for adjustable installation position. The camera itself is connected to external equipment via a cable, enabling real-time monitoring of the operating status of electrical components (such as circuit breakers and terminals) inside the switch cabinet, facilitating timely detection of equipment abnormalities by maintenance personnel.

[0005] In actual installation, each screw and nut needs to be tightened individually, which is a cumbersome and time-consuming process. Furthermore, disassembly and adjustment during subsequent maintenance are not convenient. In addition, the camera cable is fixed to the metal structure inside the switch cabinet by cable tie to organize the cable route. However, there is a lack of effective protection measures. The cable tie is usually made of nylon, and its edges or stress points after tightening may compress the cable insulation layer. Long-term vibration or temperature changes will aggravate wear, leading to the exposure of the internal conductor and causing short circuit faults.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0007] This utility model provides a switch cabinet with video monitoring function to solve the problems of cumbersome and time-consuming installation and disassembly of existing camera brackets, lack of protection for cable bundle fixing, and easy damage to the insulation layer leading to short circuits.

[0008] The present invention adopts the following technical solution: a switch cabinet with video monitoring function, mainly including a low-voltage switch cabinet, the low-voltage switch cabinet including a metal cabinet, and multiple sets of mounting brackets fixed inside the metal cabinet; a camera assembly, which is disposed on the mounting brackets, the camera assembly including a camera part fixed on the mounting bracket and capturing the operating status of electrical components inside the low-voltage switch cabinet in real time, the camera part including a support frame, a camera installed in the support frame, a locking part for fixing the camera in the mounting slot on the support frame, and a cable tie for fixing the camera cable on the mounting bracket in the same group as the camera part.

[0009] Furthermore, the camera unit includes a right-angle bracket fixed to the bottom surface of the mounting bracket, a support bracket fixed to one end of the right-angle bracket, a mounting groove on the support bracket, the camera being installed in the mounting groove, the camera having a base adapted to be inserted into the mounting groove and matching the size of the mounting groove, and the camera having a connecting cable, one end of which is connected to the PLC control system inside the cabinet.

[0010] Furthermore, the locking part includes a fixed base frame that is fixed to the bottom of the support frame and is concave in shape. Right-angle rods are fixed at both ends of the fixed base frame. A guide rod is movably inserted through the vertical end of the right-angle rod. A pressing end is fixed at one end of the guide rod. The pressing end movably inserts through the vertical end of the fixed base frame and the support frame in sequence and extends into the mounting groove. Guide grooves adapted to the size of the pressing end are opened on the vertical end of the fixed base frame and the support frame. The upper surface of the pressing end extending into the mounting groove has an inclined surface, and the lower surface has an L-shaped slot.

[0011] Furthermore, a spring is sleeved on the guide rod to provide elastic restoring force to the pressing end. One end of the spring is connected to the vertical end of the right-angle rod, and the other end is connected to one end of the pressing end.

[0012] Furthermore, the cable harness includes a concave frame fixed on the mounting bracket. The concave frame has an opening on the side near the camera. The top of the inner wall of the concave frame is provided with multiple sets of wire clips. The wire clips are hook-shaped and have notches. The width of the notches is slightly smaller than the diameter of the connecting wire.

[0013] Furthermore, the top of the clamp has a plug-in end, which is adapted to be inserted through the concave frame. A nut is threaded onto the plug-in end to fix the height of the clamp by tightening.

[0014] Furthermore, a silicone anti-slip pad is provided in the contact area between the card slot and the base of the camera.

[0015] Furthermore, a gripping part is fixed to one end of the guide rod that passes through the right-angle rod.

[0016] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0017] A switch cabinet with video surveillance function allows for quick camera positioning via the camera unit of the camera assembly through the mounting slot of the support bracket. The locking mechanism eliminates the need to tighten screws and nuts individually to secure the camera, simplifying installation, reducing labor time, and making subsequent maintenance, disassembly, and adjustments more convenient. Simultaneously, the cable management section on the mounting bracket in the same group specifically secures the camera cables. Compared to traditional nylon cable ties, this provides more stable support and protection for the cables, preventing pressure on the cable insulation layer from the edges or stress points of the cable ties. This prevents short circuits caused by insulation wear and conductor exposure due to long-term vibration and temperature changes. It ensures cable neatness, improves the operational stability of the monitoring system, and helps maintenance personnel reliably obtain real-time images of the electrical components inside the cabinet, enabling timely detection of equipment anomalies.

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-4 As shown in the figure, the present invention provides a switch cabinet with video monitoring function, including a low-voltage switch cabinet 1. The low-voltage switch cabinet 1 includes a metal cabinet 11, and an operation panel 12 is fixed on the metal cabinet 11. The operation panel 12 centrally arranges instruments, buttons and other components, which facilitates real-time monitoring and operation by the staff. Multiple sets of mounting brackets 14 are fixed inside the metal cabinet 11, which adopts a modular design. A grounding switch assembly 15 is fixed on the mounting bracket 14. It is linked with the main switch through a mechanical interlocking structure, and achieves reliable grounding during maintenance to prevent electric shock accidents. At the same time, heat dissipation holes 13 are opened on the metal cabinet 11 to provide a channel for heat dissipation of the components inside the cabinet. With the help of the internal heat dissipation structure, the temperature rise of the equipment can be effectively reduced and the life of the components can be extended.

[0029] A camera assembly 2, facing the floor switch assembly 15, is installed on a mounting bracket 14 inside the metal cabinet 11. This camera assembly 2 is used to capture real-time images of the floor switch assembly 15's operating status, providing visual data support for remote monitoring. The camera assembly 2 includes a camera unit fixed to the mounting bracket 14, which includes a right-angle bracket 21 fixed to the bottom surface of the mounting bracket 14. One end of the right-angle bracket 21 is fixed to a support frame 22, which has a mounting groove 23 in which a camera 210 is installed. The camera 210 can capture the operating status of the grounding switch assembly 15 in real time. The camera 210 has a base 211, which is suitable for insertion into the mounting slot 23 and is adapted to the size of the mounting slot 23, so as to realize the quick installation, removal and positioning of the camera 210. The camera 210 has a connecting cable 212, and one end of the connecting cable 212 is connected to the PLC control system or remote communication module in the cabinet to collect the image data of the grounding switch assembly 15, such as the open and closed status, contact wear, and presence of foreign objects, so as to ensure the continuous operation of the monitoring function.

[0030] Furthermore, a locking part is provided on the support frame 22 to reliably lock the camera 210 installed in the mounting slot 23, preventing the camera 210 from shifting due to factors such as vibration inside the cabinet, and ensuring the stability of the monitoring image. The locking part includes a fixed base frame 24 that is fixed to the bottom of the support frame 22 and is concave in shape. Right angle rods 25 are fixed at both ends of the fixed base frame 24. The vertical end of the right angle rod 25 is laterally movably inserted through a guide rod 27. One end of the guide rod 27 is fixed with a pressing end 26, which is used to directly engage the base 211 of the camera 210 to achieve mechanical locking of the camera 210. The pressing end 26 is movably inserted through the vertical end of the fixed base frame 24 and the support frame 22 in sequence, and extends into the mounting slot 23.

[0031] Meanwhile, guide grooves (not shown in the figure) adapted to the size of the pressing end 26 are provided on the vertical end of the fixed base 24 and the support frame 22, providing space and guidance for the sliding of the pressing end 26, ensuring the accurate movement trajectory of the pressing end 26. The upper surface of the pressing end 26 that extends into the mounting groove 23 has a slope, and the lower surface has an L-shaped slot. At the same time, a silicone anti-slip pad (not shown in the figure) is provided in the contact area between the slot and the base 211 of the camera 210, increasing the friction between the slot and the base 211 and improving the reliability of locking.

[0032] Furthermore, a spring 29 is sleeved on the guide rod 27 to provide elastic restoring force to the pressing end 26, ensuring that the pressing end 26 remains in a locked state when there is no external force. One end of the spring 29 is connected to the vertical end of the right-angle rod 25, and the other end is connected to one end of the pressing end 26. At the same time, a gripping part 28 is fixed at one end of the guide rod 27 that passes through the right-angle rod 25. The gripping part 28 facilitates manual pulling of the guide rod 27 to unlock the camera 210.

[0033] In actual use, when installing the camera 210, the staff aligns the base 211 of the camera 210 with the mounting groove 23 and places it downwards. The base 211 first contacts the inclined surfaces on the upper surfaces of the two sets of holding ends 26. As the base 211 continues to move downwards, the inclined surfaces are pushed by the force to slide the holding ends 26 along the guide groove to both sides. At this time, the guide rod 27 moves synchronously with the holding ends 26, and the spring 29 is compressed and accumulates elastic potential energy. When the base 211 falls completely into the mounting groove 23 and contacts the bottom of the groove, the spring 29 releases its elastic force and pushes the holding ends 26 to reset inwards. The L-shaped slots on its lower surface are precisely engaged with both sides of the base 211. With the help of the silicone anti-slip pads in the slots, the camera 210 is firmly locked, preventing the camera 210 from shifting or falling off due to vibration during cabinet operation, and ensuring stable monitoring images.

[0034] A cable management section is provided on the mounting bracket 14 in the same group as the camera unit. The cable management section is used to organize, fix and guide the connecting cable 212 in an orderly manner, so as to avoid the cable from being messy and tangled or worn due to cabinet vibration, and to ensure the stability of data transmission. The cable management section includes a concave frame 213 fixed on the mounting bracket 14. The concave frame 213 has an opening on the side near the camera 210, and multiple sets of wire clips 214 are provided on the top of the inner wall of the concave frame 213. The wire clips 214 are hook-shaped and are used to fix the connecting cable 212 to realize the cable bundling and organization.

[0035] Furthermore, the clamp 214 has a notch 215, the width of which is slightly smaller than the diameter of the connecting wire 212, so that the connecting wire 212 can be inserted into the clamp 214 through elastic deformation, while preventing the cable from accidentally coming out. At the same time, the top of the clamp 214 has a plug end 216, which is suitable for inserting into the concave frame 213. A nut 217 is threaded onto the plug end 216. By tightening to fix the height of the clamp 214, the position of the clamp 214 can be flexibly adjusted according to the direction of the connecting wire 212 to ensure that the cable layout is neat. The nut 217 fits against the upper surface of the concave frame 213.

[0036] It should be noted that in this embodiment, the camera component 2 is set only for the grounding switch assembly 15. In actual use, multiple camera components 2 can be set simultaneously at key electrical components such as circuit breakers and contactors inside the metal cabinet 11. Each camera component 2 is precisely installed and locked through components such as right-angle bracket 21 and support bracket 22. The wiring harness is used to uniformly organize the connection lines 212 of each component, thereby achieving all-round visual monitoring of multiple key nodes such as the opening and closing status of the grounding switch and the on and off status of the circuit breaker in the low-voltage switch cabinet 1. This allows maintenance personnel to grasp the operating details of the electrical components of the entire cabinet in real time through remote images, further improving the comprehensiveness and timeliness of fault diagnosis in the power distribution system. This expandable modular design is also suitable for the monitoring needs of low-voltage switch cabinets of different specifications, and has strong practicality and flexibility.

[0037] Working Principle: When the remote monitoring type low-voltage switchgear 1 is put into operation, the electrical components such as the grounding switch assembly 15 and circuit breaker inside the metal cabinet 11 complete the circuit switching and protection actions according to the power distribution requirements. At the same time, the camera assembly 2 installed on the mounting bracket 14 is activated. The camera 210 is locked by the snap-fit ​​structure between the base 211 and the mounting groove 23 and the pressing end 26 of the locking part, stably capturing the operating image of the grounding switch assembly 15. The connecting cable 212 of the camera 210 is organized by the concave bracket 213 and the wire clamp 214 of the cable bundle and then connected to the PLC control system or remote communication module inside the cabinet, transmitting the image data to the monitoring center in real time. Maintenance personnel can intuitively view the opening and closing status, contact wear and other details of the grounding switch assembly 15 through the remote platform.

[0038] If camera 210 needs to be inspected or replaced, the operator pulls the guide rod 27 through the grip 28, causing the holding end 26 to compress the spring 29 and slide along the guide groove to both sides, releasing the camera base 211 from its engagement, allowing for quick camera removal. During installation, the base 211 presses down on the inclined surface of the holding end 26. Once the base 211 falls into the bottom of the mounting groove 23, the spring 29 returns to its original position, pushing the holding end 26 to lock the base 211 in place, thus reliably fixing the camera. Simultaneously, the connecting cable 212 is inserted through the notch 215 of the cable clamp 214. The height of the cable clamp 214 can be adjusted using the plug end 216 and the nut 217 to ensure the cable is neatly arranged within the concave frame 213, preventing cable wear or tangling due to cabinet vibration and ensuring stable data transmission.

[0039] In practical applications, the same camera components 2 can be simultaneously installed on key components such as circuit breakers and contactors within the metal cabinet 11. Each component is precisely installed using modular right-angle brackets 21 and support frames 22. The wiring section uniformly organizes multiple sets of connecting wires 212, thereby achieving comprehensive visual monitoring of all electrical components in the cabinet. When any component malfunctions (such as unreliable grounding of the grounding switch or overheating of the circuit breaker contacts), the monitoring center can quickly locate the fault through real-time video. Maintenance personnel can handle the issue remotely without on-site inspection, improving the maintenance efficiency and fault response speed of the power distribution system.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
