[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a multi-in-one online monitoring device for power equipment status. This device is used for intelligent monitoring of power equipment status. Intelligent monitoring of power equipment status is designed to meet the development requirements of uninterrupted maintenance of GIS, transformers, switchgear, and cables. Based on intelligent technologies such as the Internet of Things and intelligent sensors, it enables monitoring of the operating status of power equipment under uninterrupted power conditions. Through intelligent sensor monitoring technologies such as transient ground voltage (TEV), ultrasonic (AE & Ultrasonic), ultra-high frequency (UHF), high-frequency current (HFCT), ozone, and temperature, it achieves intelligent perception of the operating status of transformers, GIS, switchgear, and power cables. Through intelligent diagnostic algorithms and multi-dimensional comparative analysis, it achieves intelligent analysis of monitoring data and intelligent diagnosis of equipment status, enabling real-time monitoring of operating status, timely detection of defects and problems, and evaluation and push of abnormal information and maintenance strategy suggestions. This provides data support for maintenance personnel to formulate maintenance strategies, effectively preventing sudden power outages, fires, and personal injury or equipment damage. It can be installed and maintained on-site while the power grid equipment is energized, without affecting the operation of the power grid equipment or the reliability of power supply. The intelligent sensor adopts a miniaturized, modular, high-performance, and low-power design, with a built-in battery capacity that supports more than 5 years of operation. It supports multiple partial discharge monitoring methods: UHF, AE, TEV, high-frequency current, ozone, temperature, etc., and features both wired and active monitoring. The sensor supports various deployment schemes, including "wireless and passive," and supports multiple wireless communication protocols such as the State Grid power transmission and transformation equipment IoT sensor data communication protocol and LoRaWAN, as well as wired communication protocols such as Modbus. It is equipped with intelligent power equipment status monitoring system software, offering comprehensive data analysis capabilities. Users can freely select time, parameters, historical trend analysis of multiple measurement points, and horizontal comparative analysis. Simultaneously, it integrates intelligent diagnostic algorithms for monitoring data, achieving a diagnostic accuracy rate of over 90%. The intelligent monitoring system supports local deployment, cloud deployment, and private deployment, enabling stable operation 24 / 7. Both the sensor and monitoring host possess edge computing capabilities, providing early warnings, alarms, and normal status diagnoses based on comprehensive judgment of historical data from various parameters. The multi-functional online monitoring device includes a housing with open ends on both sides. Equally spaced heat dissipation slots are provided on the front and rear sides of the housing. Fixing strips are fixedly connected to the front and rear outer walls of the housing, and a rotating rod is rotatably connected to each fixing strip. One end of the rotating rod is a weight-bearing end. A protective mechanism is provided on the outer wall of the housing. A fixing plate is fixedly connected to the right end of the housing. Rotating plates are provided at the front and rear ends of the housing. Two transverse T-shaped sliding grooves are provided on the front and rear sides of the outer wall of the housing. A connecting block is fixedly connected to the left end of the housing, and a connector with a hole is rotatably connected to the connecting block. A placement groove is provided in the middle part of the fixing plate.

[0006] As a preferred embodiment of the present invention, a display screen is movably connected in the placement slot, and a connecting slot is provided at each of the four corners of the display screen. Four screws are fixedly connected to the fixing plate.

[0007] As a preferred embodiment of the present invention, each screw is threaded with a threaded ring, and the screw is movably connected to the connecting groove on the display screen. Two short frames are fixedly connected to the threaded ring, and auxiliary rings for auxiliary rotation are fixedly connected to the two short frames. The threaded ring is movably pressed against the fixed plate. By rotating the rotating plate, the horizontal rotating rod passes through the horizontal groove, and the rotating plate can rotate normally. The vertical rotating rod will jam the rotating plate, so that the position of the rotating plate remains stable. The rotating plate stops when it contacts the right end of the protective frame. At this time, the movable frame is pulled by the pull ring, so that the two round rods on the movable frame are respectively inserted into the holes on the two limit blocks, so that the position of the rotating plate can no longer move. At this time, the two rotating plates remain closed, achieving the effect of protecting the display screen.

[0008] As a preferred embodiment of the present invention, an inner frame is movably fitted inside the outer shell of the device. The inner frame has the same heat dissipation groove. The intelligent gateway device of the monitoring host is fixedly installed inside the inner frame. A connector with holes is fixedly connected to the inner frame. When the monitoring device is used, the rotating plate is kept in contact with the protective frame by the vertical rotating rod. At this time, the protective frame can be slid, and the locking block slides in the T-shaped sliding groove. When the locking block slides to the rightmost end of the T-shaped sliding groove, the protective frame reaches the farthest sliding distance. At this time, the protective frame can play a role in blocking light, making it easier for the operator to observe clear screen information, and at the same time, it can also achieve the effect of protecting the display screen.

[0009] As a preferred embodiment of the present invention, the rotating plate is provided with a horizontal groove, which is movably engaged with a fixing strip. A limiting block with a hole is fixedly connected to the upper end of the rotating plate. The protection mechanism includes a protective frame, which is a structure composed of a horizontal plate and two vertical plates. The inner wall of the protective frame is movably fitted with the outer wall of the device housing.

[0010] As a preferred embodiment of the present invention, a crossbeam is fixedly connected to the right end of the protective frame, and the two ends of the crossbeam are rotatably connected to two rotating plates respectively. A middle groove is provided in the middle part of the upper crossbeam, and two pairs of T-shaped locking blocks are provided on the inner wall of the protective frame. The locking blocks are movably engaged with the T-shaped sliding grooves. Connector 1 and connector 2 are connected by a lock. After the lock is opened, the outer shell of the device can be separated from the inner frame, which facilitates the disassembly, assembly and maintenance of the equipment inside the inner frame.

[0011] As a preferred embodiment of the present invention, a movable frame is fixedly connected to the upper surface of the protective frame, a pull ring is fixedly connected to the movable frame, two round rods are fixedly connected to the movable frame, and a limit ring is fixedly connected to each of the two round rods.

[0012] As a preferred embodiment of the present invention, a middle rod is fixedly connected to the limiting frame, a stop block is fixedly connected to the end of the middle rod, and two springs are also fixedly connected to the limiting frame. The two springs are respectively movably sleeved with two round rods, and the two ends of the springs are respectively fixedly connected to the movable frame and the limiting frame.

[0013] As a preferred embodiment of the present invention, the two slots are respectively movably connected to the two round rods. The middle part of the movable frame is provided with a through groove, which is movably connected to the middle rod. By rotating the screw ring through the auxiliary ring, the screw ring can be disengaged from the screw rod, which facilitates the separation of the display screen from the fixing plate and the disassembly and assembly of the display screen.

[0014] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0015] 1. By rotating the rotating plate, the horizontal rotating rod passes through the horizontal groove, allowing the rotating plate to rotate normally. The vertical rotating rod will lock the rotating plate, keeping its position stable. The rotating plate stops when it contacts the right end of the protective frame. At this point, the movable frame is pulled by the pull ring, causing the two round rods on the movable frame to insert into the holes on the two limit blocks, preventing the rotating plate from moving any further. The two rotating plates remain closed, achieving the effect of protecting the display screen.

[0016] 2. When using the monitoring equipment, the vertical rotating rod keeps the rotating plate in contact with the protective frame. At this time, the protective frame can be slid, and the locking block slides in the T-shaped slide groove. When the locking block slides to the rightmost end of the T-shaped slide groove, the protective frame reaches its farthest sliding distance. At this time, the protective frame can play a role in blocking light, making it easier for operators to observe clear screen information, and at the same time, it can also achieve the effect of protecting the display screen.

[0017] 3. Connector 1 and connector 2 are connected by a lock. After the lock is opened, the outer shell of the device can be separated from the inner frame, which facilitates the disassembly, assembly and maintenance of the equipment inside the inner frame.

[0018] 4. By rotating the auxiliary ring, the screw ring can be disengaged from the screw, facilitating the separation of the display screen from the fixing plate and the disassembly and assembly of the display screen.

The system includes functional modules such as site overview, monitoring data analysis, early warning and alarm management, monitoring instrument management, file management, user center, and system management. It accesses monitoring data via protocols such as MQTT and utilizes diagnostic algorithms and multi-dimensional comparative analysis to achieve intelligent diagnosis of monitoring data and equipment status.

[0020] 6. Utilizing intelligent sensor technology, the system collects real-time status signals such as temperature, ultrasound, transient ground voltage, ultra-high frequency (UHF), high-frequency current, and ozone. Through the management and coordination of various intelligent sensors and intelligent gateways, it receives real-time monitoring data, performs intelligent data analysis, and provides support for the status management of power equipment. The intelligent power equipment status monitoring system software can be deployed on a monitoring host or cloud platform, depending on the application scenario.
