Description

Technical Field

[0001] This invention relates to the field of substation technology, specifically to an unattended intelligent substation video monitoring device and its monitoring method. Background Technology

[0002] An unattended intelligent substation video monitoring device is a piece of equipment installed inside or around a substation to monitor its operational status, safety, and surrounding environment in real time. It primarily uses cameras and related sensors for data acquisition and transmission. It has the following features and functions: Video monitoring: The device is equipped with cameras that provide real-time video monitoring images, including power equipment, transmission lines, and distribution areas. This helps staff or remote operation centers monitor the substation's operation, promptly detect anomalies or faults, and take appropriate measures.

[0003] However, substations are electrical facilities used to transform voltage and power. Although the design and construction of substations strictly adhere to safety standards and regulations, some potential fire risks still exist. The following are some situations that may lead to substation fires: Short circuit faults: Short circuits in the power system can cause high currents to flow through equipment and cables, potentially causing a fire; Overload problems: When the power load exceeds the substation's capacity, it can cause cables and equipment to overheat, leading to a fire; Aging electrical equipment: After prolonged operation, electrical equipment may become aged, such as aging cable insulation or loose equipment connections, all of which can pose a fire risk; Leaks of flammable substances: Substations may store flammable chemicals such as oil, paint, and solvents. If a leak occurs and comes into contact with an ignition source, it could potentially cause a fire. After a fire, cameras used for real-time video surveillance are highly susceptible to damage due to high temperatures. When a camera is damaged due to high temperatures or other reasons, the video surveillance system will lose its function and may not be able to accurately detect the location and extent of the anomaly or fire in the first instance. This may delay the time for firefighting and emergency response. After a fire, due to camera damage, real-time monitoring video cannot be obtained until the camera is repaired or replaced, which will bring difficulties to maintenance and repair.

[0014] This invention also discloses a monitoring method for an unattended intelligent substation video monitoring device, the specific method of which is as follows: 1) When a fire occurs at the location where the camera body is installed, the heat conduction block is conducted by the external ambient temperature, and then the heat conduction block conducts the temperature through the heat conduction rod, which can heat the expansion liquid inside the storage chamber. At this time, the expansion liquid inside the storage chamber expands due to heat and drives the sealing plate to slide, which can start the circulating water pump by touching the touch switch. 2) At this time, after the circulating water pump works, it can make cold water circulate inside the cooling tank to keep the camera body at a constant temperature, so that the camera body is not affected by the external temperature and can continue to work normally. 3) When the internal temperature of the camera body rises after prolonged use, the heat conduction through the arc plate inside the camera body can also heat up the heat conduction rod, and at the same time drive the sealing plate to slide and trigger the touch switch, and dissipate heat to the whole body through the circulation of cold water inside the cooling tank. 4) When the camera body has been used for a long time, the rotating structure may make abnormal noise due to lack of oil. This noise will be collected by the noise sensor and then controlled by the controller to start the drive motor. This will increase the pressure inside the limit groove, causing the sealing rod to slide to the outside of the lower oil groove. The lubricating oil inside the oil storage groove will automatically flow into the surface of the positioning bearing through the lower oil groove, which will have a lubricating effect and extend the service life of the rotating structure of the camera body.

[0015] Beneficial effects of the invention Compared with the prior art, the present invention provides an unattended intelligent substation video monitoring device and its monitoring method, which has the following beneficial effects: 1. This unattended intelligent substation video monitoring device and its monitoring method, by setting up a cooling tank and a drive device, allows the expansion liquid inside the storage chamber to be heated through the heat conduction block when a fire occurs at the location where the camera body is installed. Then, through the sliding of the sealing plate, the circulating water pump can be started by contacting the tactile switch, allowing cold water to circulate inside the cooling tank. This ensures that the camera body is not affected by the external temperature and can continue to operate normally. If the camera continues to work, it can provide real-time video monitoring to help understand the development of the fire. This can help firefighters make more accurate judgments and decisions, including the size of the fire, the range of combustion, and the path of fire spread.

[0016] 2. The unattended intelligent substation video monitoring device and its monitoring method can not only monitor the external temperature in real time by setting up a drive device, but also detect the internal temperature of the camera body through the heat conduction of the arc plate. When the internal temperature of the camera body rises, it can also dissipate heat through the circulation of cold water in the cooling tank, thereby improving the heat dissipation efficiency of the camera body.

[0017] 3. The unattended intelligent substation video monitoring device and its monitoring method, by setting up an oil storage tank and sealing rod, etc., when the camera body has been used for a long time, the rotating structure may lack oil. When abnormal noise caused by lack of oil occurs during rotation, it will be collected by a noise sensor, and then controlled by the controller to start the drive motor, which will increase the pressure inside the limit groove, causing the sealing rod to slide to the outside of the lower oil tank. The lubricating oil inside the oil storage tank will automatically flow into the surface of the positioning bearing through the lower oil tank, achieving a lubrication effect. After lubrication is completed, the abnormal noise disappears. The sealing rod seals the lower oil tank, stops the flow of lubricating oil, and extends the service life of the rotating structure of the camera body. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Please see Figure 1-6An unattended intelligent substation video monitoring device includes a camera body 1. The camera body 1 has a cooling tank 2 inside, which is serpentine.

Heat-conducting rods 4 are fixedly connected at equal intervals to the outer surface of the heat-absorbing plate 3. A heat dissipation plate 5 is fixedly connected to the end of the heat-conducting rods 4 away from the heat-absorbing plate 3. The heat-absorbing plate 3, heat-conducting rods 4 and heat dissipation plate 5 are all made of copper. The heat dissipation plate 5 is arc-shaped and the heat-absorbing plate 3 is annular. A circulating water pump 6 is fixedly installed at the output end of the cooling tank 2. A water inlet pipe connector 7 is fixedly connected to the output end of the circulating water pump 6. A water outlet pipe connector 8 is fixedly connected to the output end of the cooling tank 2. A driving device 9 is fixedly installed on the outer surface of the camera body 1.

The fixing disk 99 is annular, and its surface has through holes 991 at equal intervals. A tactile switch 910 is fixedly connected to the center of the fixing disk 99. 910 is electrically connected to the circulating water pump 6. The inner side of the fixing block 91 is provided with a vent hole 911. By setting up the cooling tank 2 and the drive device 9, when a fire occurs at the location where the camera body 1 is installed, the heat conduction block 95 can heat the expansion liquid inside the liquid storage chamber 92. Then, by sliding the sealing plate 96, the circulating water pump 6 can be started by touching the tactile switch 910, allowing cold water to circulate inside the cooling tank 2. This prevents the camera body 1 from being affected by the external temperature, allowing the camera body 1 to continue to work normally. The drive device 9 can also detect the internal temperature of the camera body 1. When the internal temperature of the camera body 1 rises, the cold water circulation inside the cooling tank 2 can also dissipate heat from the entire body, improving the heat dissipation efficiency of the camera body 1.

A base 11 is installed at the bottom of the rotating base 10. A sound insulation cotton 12 is fixedly connected to the bottom of the rotating base 10. The sound insulation cotton 12 has a "U" shaped cross-section. The inner wall of the sound insulation cotton 12 is attached to the surface of the base 11. A positioning bearing 13 is fixedly installed at the center of the base 11. A rotating shaft 14 is fixedly connected inside the positioning bearing 13. The top of the rotating shaft 14 is fixedly connected to the center of the bottom of the rotating base 10. A driven gear 15 is fixedly connected to the end of the rotating shaft 14 away from the rotating base 10. A stepper motor 16 is fixedly installed inside the base 11. A drive gear 17 is fixedly connected to the output end of the stepper motor 16. The surface of the drive gear 17 is meshed with the surface of the driven gear 15. The rotating base 10 can be rotated by starting the stepper motor 16. By setting the sound insulation cotton 12, external sound is not easily transmitted between the rotating base 10 and the base 11. The rotating seat 10 has an oil reservoir 18 inside, which is filled with lubricating oil. Above the oil reservoir 18, there is an oil filling groove 19 inside the rotating seat 10 that communicates with the inside of the oil reservoir 18. A plug 20 is threadedly sealed at the top of the oil filling groove 19. The bottom of the rotating seat 10 has a lower oil groove 21 that communicates with the inside of the oil reservoir 18. A noise sensor 22 is fixedly installed at the bottom of the rotating seat 10. A limit groove 231 is opened inside the rotating seat 10. A sealing rod 23 is slidably connected inside the limit groove 231. An air vent 232 is opened at the bottom of the rotating seat 10 that communicates with the inside of the limit groove 231. The surface of the sealing rod 23 abuts against a second spring. Spring 24, sealing rod 23 is sealed and inserted into the lower oil groove 21 at the end away from the second spring 24. The diameter of the end of sealing rod 23 near the second spring 24 is larger than the diameter of the other end. An adjustment groove 25 is provided inside the rotating seat 10. The inside of the adjustment groove 25 and the inside of the limiting groove 231 are connected to the outside of the rotating seat 10 through the air outlet pipe 32. The inside of the adjustment groove 25 is connected to the inside of the air outlet pipe 32 through the vent pipe 33. An adjustment block 26 is slidably connected to the inside of the adjustment groove 25. A connecting plate 27 is rotatably connected to the surface of the adjustment block 26. A drive motor 28 is fixedly installed inside the rotating seat 10. A cam 29 is fixedly connected to the output end of the drive motor 28. The end of 27 furthest from the adjusting block 26 is rotatably connected to the surface of the cam 29. A connecting pipe 30 is fixedly connected inside the rotating seat 10. The diameter of the vent 232 is smaller than the diameter of the connecting pipe 30. The interior of the limiting groove 231 is connected to the interior of the adjusting groove 25 through the connecting pipe 30. A first one-way valve 31 is fixedly installed inside the connecting pipe 30. The input end of the first one-way valve 31 is close to the interior of the adjusting groove 25. A vent pipe 33 is fixedly installed inside the rotating seat 10. A second one-way valve 34 is fixedly installed inside the vent pipe 33.

The bottom of the base 11 is fixed. The camera body 1 is connected to a fixed bracket 35. By setting an oil storage tank 18 and a sealing rod 23, the rotating structure may lack oil after the camera body 1 has been used for a long time. When there is abnormal noise caused by lack of oil during rotation, it will be collected by the noise sensor 22. Then, the controller will control the drive motor 28 to start, which will increase the pressure inside the limit groove 231, causing the sealing rod 23 to slide to the outside of the lower oil groove 21. The lubricating oil inside the oil storage tank 18 will automatically flow into the surface of the positioning bearing 13 through the lower oil groove 21, which will have a lubricating effect. After the lubrication is completed, the abnormal noise will disappear. The sealing rod 23 seals the lower oil groove 21, stops the flow of lubricating oil, and extends the service life of the rotating structure of the camera body 1. An vent hole 201 is provided at the center of the plug 20. A filter sponge 202 is placed inside the plug 20. A metal mesh plate 203 is attached to the outer surface of the plug 20. Magnets 204 are fixedly installed on the opposite sides of the metal mesh plate 203 and the plug 20. By setting the sponge 202, external dust can be prevented from entering the oil reservoir 18. By setting the vent hole 201, the negative pressure state inside the oil reservoir 18 can be prevented, thus ensuring the smooth flow of lubricating oil.

[0023] This invention also discloses a monitoring method for an unattended intelligent substation video monitoring device, the specific method of which is as follows: 1) When a fire occurs at the location where the camera body 1 is installed, the heat conduction block 95 is conducted by the external ambient temperature, and then the heat conduction block 95 conducts the temperature through the heat conduction rod 93, which can heat the expansion liquid inside the liquid storage chamber 92. At this time, the expansion liquid inside the liquid storage chamber 92 expands due to heat and drives the sealing plate 96 to slide, which can start the circulating water pump 6 by touching the touch switch 910. 2) At this time, after the circulating water pump 6 starts working, it can make cold water circulate inside the cooling tank 2 to keep the camera body 1 at a constant temperature, so that the camera body 1 is not affected by the external temperature and can continue to work normally. 3) When the internal temperature of the camera body 1 rises after prolonged use, the heat conduction of the arc plate 94 inside the camera body 1 can also heat up the heat conduction rod 93, and at the same time drive the sealing plate 96 to slide and trigger the light touch switch 910, so that the cold water inside the cooling tank 2 can dissipate heat to the whole body. 4) When the rotating structure of the camera body 1 has been used for a long time, it will make abnormal noise due to lack of oil. This noise will be collected by the noise sensor 22 and then controlled by the controller to start the drive motor 28. This will increase the pressure inside the limit groove 231, causing the sealing rod 23 to slide to the outside of the lower oil groove 21. The lubricating oil inside the oil storage groove 18 will automatically flow into the surface of the positioning bearing 13 through the lower oil groove 21, which will have a lubricating effect and extend the service life of the rotating structure of the camera body 1.

[0024] In summary, when this unattended intelligent substation video monitoring device is in use, and a fire occurs at the location where the camera body 1 is installed, the heat-conducting block 95 is rapidly heated through the conduction of the external ambient temperature. Then, the heat-conducting block 95 conducts the temperature through the heat-conducting rod 93, which heats the expansion liquid inside the liquid storage chamber 92. At this time, the expansion liquid inside the liquid storage chamber 92 expands due to heat, causing the sealing plate 96 to slide. This allows the circulating water pump 6 to be activated by contacting the tactile switch 910. After the circulating water pump 6 starts working, cold water circulates inside the cooling tank 2, maintaining a constant temperature for the camera body 1. This ensures that the camera body 1 is not affected by the external temperature and can continue to operate normally. If the camera can continue to work, it can provide real-time video monitoring to help understand the development of the fire. This can help firefighters make more accurate judgments and decisions, including the size of the fire, the range of combustion, and the path of fire spread. When the internal temperature of the camera body 1 rises after prolonged use, the heat conduction of the arc plate 94 inside the camera body 1 can also heat up the heat conduction rod 93, and at the same time drive the sealing plate 96 to slide and trigger the light touch switch 910. When the internal temperature of the camera body 1 rises, it can also dissipate heat through the circulation of cold water inside the cooling tank 2, thereby improving the heat dissipation efficiency of the camera body 1. When the camera body 1 has been used for a long time, the rotating structure may become dry. When abnormal noise caused by insufficient oil occurs during rotation, it will be collected by the noise sensor 22 and then controlled by the controller to start the drive motor 28. When the drive motor 28 starts, it will drive the cam 29 to rotate, which will slide through the connecting plate 27 and the adjusting block 26. Then, through the cooperation of the second one-way valve 34 and the first one-way valve 31, the sliding process of the adjusting block 26 will pressurize the inside of the limiting groove 231, causing the sealing rod 23 to slide outside the lower oil groove 21. The lubricating oil inside the oil storage tank 18 will automatically flow into the surface of the positioning bearing 13 through the lower oil groove 21, which will have a lubricating effect. After lubrication, the abnormal noise will disappear, the drive motor 28 will stop starting, and the air pressure inside the limiting groove 231 will slowly be discharged through the air outlet 232. At this time, the sealing rod 23 will seal the lower oil groove 21 through the elasticity of the second spring 24, stopping the flow of lubricating oil and extending the service life of the rotating structure of the camera body 1.

10. A monitoring method for an unattended intelligent substation video monitoring device according to any one of claims 1-9, characterized in that, The method includes: 1) When a fire occurs at the location where the camera body (1) is installed, the heat conduction block (95) is conducted by the external ambient temperature, and then the heat conduction block (95) conducts the temperature through the heat conduction rod (93), which can heat the expansion liquid inside the liquid storage chamber (92). At this time, the expansion liquid inside the liquid storage chamber (92) expands due to heat and drives the sealing plate (96) to slide, which can start the circulating water pump (6) by touching the light switch (910). 2) At this time, after the circulating water pump (6) works, it can make cold water circulate inside the cooling tank (2) to keep the camera body (1) constant temperature, so that the camera body (1) is not affected by the external temperature and the camera body (1) can still maintain normal operation. 3) When the internal temperature of the camera body (1) rises after prolonged use, the heat conduction of the arc plate (94) inside the camera body (1) can also heat up the heat conduction rod (93), and at the same time drive the sealing plate (96) to slide and trigger the light touch switch (910), and cool the whole body through the cold water circulation inside the cooling tank (2); 4) When the rotating structure of the camera body (1) has been used for a long time, there will be abnormal noise caused by lack of oil. The noise will be collected by the noise sensor (22) and then the controller will control the drive motor (28) to start. This will increase the pressure inside the limit groove (231) and make the sealing rod (23) slide to the outside of the lower oil groove (21). The lubricating oil inside the oil storage groove (18) will automatically flow into the surface of the positioning bearing (13) through the lower oil groove (21), which will have a lubricating effect and extend the service life of the rotating structure of the camera body (1).
