[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] The following is an explanation of the preferred embodiments of the device of the utility model.

[0023] See also Figure 1-4As shown, the substation auxiliary monitoring device includes a bracket 1, a motor mounting plate 2 is provided on the top outer side of the bracket 1, a servo motor 3 is fixedly mounted on the motor mounting plate 2, and the servo motor 3 serves as a power source. Its installation enables the device to accurately control movement and provide stable power output for subsequent lifting and rotating actions. A bearing fixing seat 4 is provided on the other side of the top of the bracket 1. The output end of the servo motor 3 horizontally penetrates the top outer side of the bracket 1 and is connected to a driving shaft 5, and the other end of the driving shaft 5 is fixedly connected to the bearing fixing seat 4. Both ends of the driving shaft 5 are sleeved with driving sprockets 6. A driven sprocket 7 is correspondingly provided on the inner side of the bottom of the bracket 1. The driven sprocket 7 is connected with a driven shaft 701 through a mounting hole, and the driven shaft 701 horizontally penetrates to the outer side of the bottom of the bracket 1, and is connected to the driving shaft 5 through the output end of the servo motor 3. The smooth rotation of the shaft is ensured by the bearing fixing seat 4. The two ends of the driving shaft 5 are sleeved with driving sprockets 6. This combination enables the power of the servo motor 3 to be effectively transmitted to the driven sprocket 7 through the chain transmission system, thereby driving the movement of the entire lifting mechanism. The inner side of the bracket 1 and located at the main The front and rear ends of the moving sprocket 6 are vertically provided with slide rails 8, and a slider 9 is fixedly sleeved on the slide rail 8. The slider 9 is fixedly connected to a connecting plate 10 on the side away from the slide rail 8, and a chain connecting piece 11 is provided on the other side of the connecting plate 10. The driving sprocket 6 and the driven sprocket 7 are wrapped with chains through the chain connecting piece 11, and the chain connecting piece 11 and the driving sprocket 6 and the driven sprocket 7 are located in the same vertical plane. Specifically, the driving sprocket 6 and the driven sprocket 7 form a transmission system through the chain connecting piece 11 and the chain to transmit power to the connecting plate 10. Since the side of the connecting plate 10 away from the slider 9 is connected to the chain connecting piece 11, the connecting plate 10 and the components thereon can be lifted and lowered along the slide rail 8 under the drive of the chain transmission system, thereby realizing the lifting function of the device, enabling the monitoring equipment to flexibly adjust the height, and expanding the monitoring range.

[0024] Furthermore, a crossbeam 12 is provided between the connecting plates 10, and two groups of crossbeams 12 are horizontally arranged. The crossbeams 12 strengthen the stability of the entire structure. Reinforcing rods 13 are longitudinally arranged between the crossbeams 12 to further enhance the stability and bearing capacity of the structure. A mounting seat 14 is provided on the front side of the crossbeam 12, a mounting rod 16 is provided on the side of the mounting seat 14, and a mounting block 15 is connected to the top of the mounting rod 16. A monitoring device body 18 is fixedly installed on the mounting block 15 through a bearing fixing seat 17. This combination enables the monitoring device body 18 to be stably installed on the device and facilitates angle adjustment.

[0025] Furthermore, a plurality of groups of spring limit columns 19 are provided on the front and rear sides of the bracket 1, and a transparent baffle 20 is connected to the side of the spring limit column 19 away from the bracket 1, and a plurality of induction signal lights 21 are installed on the concave side of the transparent baffle 20. Specifically, when the device is subjected to a collision impact, the spring limit column 19 not only provides support for the transparent baffle 20, but also plays a buffering role when it is subjected to an impact, and the collision suffered by the transparent baffle 20 will be sensed by the induction signal light 21, and the induction signal light 21 will light up at this time. Through the transparency of the transparent baffle 20, the collision personnel can clearly see the warning signal. This combination improves the safety and warning effect of the device, wherein the servo motor 3 and the induction signal light 21 are both existing mature technologies and will not be elaborated here.

[0026] Among them, when the device is connected to the software of the substation auxiliary monitoring system, it adopts a variety of network interfaces and protocols to meet the needs of different subsystems.

[0027] For the security guard subsystem, access control, electronic fence, smart locks, etc. are connected through the 485 interface. The infrared beam is connected to the security guard subsystem through a relay. This diverse interface method ensures that the security guard subsystem can fully and accurately receive and process various security-related information.

[0028] In the meteorological and dynamic environment subsystem, sensors such as temperature and humidity, lighting, and wind speed are connected using 485 interfaces. At the same time, water immersion, fans, air conditioners and other equipment are connected using relays. This design not only ensures the stability of data transmission, but also improves the response speed of the system.

[0029] The fire alarm subsystem is directly connected to the system via IEC61850 wired mode, ensuring that fire information can be quickly and accurately transmitted to the monitoring center, providing a strong guarantee for the timely discovery and handling of fires.

[0030] In the primary equipment online monitoring subsystem, the main transformer equipment online monitoring IED / backstage and other equipment are connected via IEC61850 wired mode. This standardized connection method ensures the accuracy and real-time nature of the data, and provides reliable data support for equipment status monitoring and fault diagnosis.

[0031] For the video and intelligent patrol subsystem, robots and drones are connected to the system via TCP / IP protocol wired or wirelessly. At the same time, the camera is also connected to the video NVR via TCP / IP protocol wired, and then connected to the video and intelligent patrol subsystem. This design enables video data to be transmitted to the monitoring center in real time and smoothly, providing clear video data for intelligent patrol.

[0032] When in use, the servo motor 3 is first started. After receiving the command, the servo motor 3 starts working and drives the active shaft 5 to rotate. The rotation of the active shaft 5 drives the active sprocket 6 to rotate. Through the assembly of the chain connector 11 and the chain, a chain transmission system is formed between the active sprocket 6 and the driven sprocket 7, which effectively transmits the rotational power of the servo motor 3 to the driven sprocket 7. The transmission of the chain causes the connecting plate 10 to slide up and down along the slide rail 8. Since the connecting plate 10 is connected to the monitoring device body 18 through the mounting block 15 and the mounting rod 16, the monitoring device body 18 also rises and falls accordingly, realizing flexible monitoring of devices at different heights. During the operation of the device, when the transparent baffle 20 is collided, the spring limit column 19 is set to effectively buffer the impact caused by the collision, and the collision effect will trigger the induction signal light 21 to light up or flash, reminding the collision personnel to pay attention, providing real-time protection and warning functions.
