Detailed Implementation
[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0026] Example 1:
[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an intelligent ring main unit monitoring device includes a cabinet 10. A cabinet door 11 is hinged to one side of the cabinet 10. A common lock is installed between the cabinet 10 and the cabinet door 11, providing basic anti-theft protection for the ring main unit. A top cover 12 is installed on the top of the cabinet 10, providing good rain protection for outdoor use. A first through hole 13 is provided on the upper surface of the cabinet 10. A first sliding sealing plate 14 is slidably installed inside the first through hole 13. A second sliding sealing plate 15 is installed above the first sliding sealing plate 14 and slides synchronously with it. A second through hole 16 is provided on the upper surface of the second sliding sealing plate 15. An exhaust fan 19 is installed at the upper end of the second through hole 16 and the upper surface of the second sliding sealing plate 15. The exhaust fan 19 is a waterproof exhaust fan, which is existing technology. The input port of the exhaust fan 19 is connected to the second through hole 16. A filter cover 17 is provided at the lower end of the second sliding sealing plate 15 at the lower port of 6. A monitoring probe 18 is connected to the lower end of the filter cover 17. The monitoring probe 18 is a 360-degree all-round monitoring device. The internal monitoring probe can rotate 360 degrees. The external part is provided with a transparent hemispherical protective cover, which has good waterproof and moisture-proof functions. This is the existing technology. After the exhaust fan 19 is started, the exhaust fan 19 exhausts the air inside the filter cover 17 through the second through hole 16. During the process of exhausting the gas, the airflow will flow to the outside of the monitoring probe 18 and then enter the filter cover 17, thereby forming a stable gas flow outside the monitoring probe 18, improving heat dissipation efficiency, and ensuring that the monitoring probe 18 can perform monitoring work for a long time without interruption. Moreover, the filter cover 17 can also filter the air entering the filter cover 17, preventing impurities in the air from moving into the filter cover 17 and the exhaust fan 19, reducing unnecessary maintenance costs.
[0028] When the monitoring probe 18 and other components move into the cabinet 10 along with the first sliding sealing plate 14 and the second sliding sealing plate 15 to monitor the interior of the cabinet 10, the second sliding sealing plate 15 will form a snap-fit seal with the first through hole 13, ensuring the overall airtightness of the ring main unit. Simultaneously, by activating the exhaust fan 19, the gas inside the cabinet 10 can be extracted through the filter cover 17, allowing for rapid airflow within the cabinet 10. This dissipates some heat and moisture, ensuring a normal operating environment for the electronic components inside the cabinet 10. The cabinet 10 is equipped with multiple temperature sensors 30 and humidity sensors. The temperature sensor 30 and humidity sensor 31 are all common sensors, which are existing technologies. They can monitor the real-time temperature and humidity inside the cabinet door 11. The control system between the temperature sensor 30 and humidity sensor 31 controls the up and down movement of components such as the exhaust fan 19 and cools and dehumidifies the inside of the cabinet 10. Multiple infrared human body sensors 27 are installed on the outer end face of the cabinet door 11. The infrared human body sensors 27 can monitor personnel approaching the ring network cabinet. When someone approaches the ring network cabinet, the monitoring probe 18 and other components move out from inside the cabinet door 11 to record video and issue warnings to the person.
[0029] Furthermore, such as Figure 5 As shown, a cooling plate 36 is provided on the upper surface of the monitoring probe 18 inside the filter cover 17. The cooling plate 36 is a metal structure with high heat conduction efficiency, which can absorb and conduct the heat generated by the monitoring probe 18 when it is working. The air inside the filter cover 17 is circulated by the exhaust fan 19, which forms a cooling treatment for the cooling plate 36, and then forms a cooling treatment for the monitoring probe 18, thereby further improving the cooling effect of the monitoring probe 18.
[0030] Furthermore, such as Figure 4 and Figure 5As shown, support rods 20 are connected to both sides of the monitoring probe 18 between the first sliding sealing plate 14 and the second sliding sealing plate 15. The two support rods 20 fix the first sliding sealing plate 14 and the second sliding sealing plate 15, ensuring the synchronicity of the vertical sliding of the first sliding sealing plate 14 and the second sliding sealing plate 15. An arc-shaped scraper 21 is rotatably arranged between the two support rods 20. A removable cleaning cotton strip 22 is provided on the inner arc surface of the arc-shaped scraper 21. A groove and a retaining strip are provided between the arc-shaped scraper 21 and the cleaning cotton strip 22 to facilitate the replacement and cleaning of the cleaning cotton strip 22, ensuring the cleaning effect of the cleaning cotton strip 22 on the outer spherical surface of the monitoring probe 18. The inner arc surface of the cleaning cotton strip 22 is in contact with the monitoring probe. The outer spherical surface of the head 18 slides against the arc-shaped scraper 21. Both ends of the arc-shaped scraper 21 are provided with a first rotating shaft. Each first rotating shaft is rotatably connected to its adjacent support rod 20. One side of one of the first rotating shafts is provided with a first motor 23 on the side wall of the support rod 20. The output end of the first motor 23 is fixedly connected to one of the first rotating shafts. The first motor 23 is a servo motor. Its output shaft has a high-precision rotation adjustment function and can adjust the rotation angle according to the needs, thereby driving the first rotating shaft to rotate. The first rotating shaft drives the arc-shaped scraper 21 to rotate, and the arc-shaped scraper 21 drives the cleaning cotton strip 22 to rotate, so that the cleaning cotton strip 22 cleans and wipes the outer spherical surface of the monitoring probe 18, ensuring the monitoring clarity of the monitoring probe 18.
[0031] It should be noted that the monitoring angle of the monitoring probe 18 will be adjusted according to the different monitoring environments of the monitoring probe 18 inside or outside the cabinet 10. At this time, the arc-shaped scraper 21 and the cleaning cotton strip 22 will be rotated to the side opposite to the monitoring direction of the monitoring probe 18 to avoid obstructing the monitoring angle of the monitoring probe 18.
[0032] Furthermore, such as Figure 1 and Figure 4As shown, a hollow rod 32 is provided on one side of each support rod 20 between the first sliding sealing plate 14 and the second sliding sealing plate 15. The two hollow rods 32 increase the connection stability between the first sliding sealing plate 14 and the second sliding sealing plate 15. A screw 34 is rotatably provided above one of the hollow rods 32 on the lower end face of the top cover 12, and is threadedly connected to the hollow rod 32 below it. A third motor 35 is provided above the screw 34 on the upper end face of the top cover 12. The output end of the third motor 35 is fixedly connected to the top of the screw 34. The third motor 35 is a servo motor, and its output shaft has a high-precision rotation adjustment function. Yes, the rotation angle can be adjusted according to the requirements. The output end of the third motor 35 drives the screw 34 to rotate. The screw 34 is connected to the hollow rod 32 by a thread, which allows the hollow rod 32 to slide up and down outside the screw 34, thereby pushing the first sliding sealing plate 14 and the second sliding sealing plate 15 and other components to slide inside the first through hole 13. A guide rod 33 is fixedly provided above the hollow rod 32 on the lower end face of the top cover 12. The guide rod 33 is slidably connected to the hollow rod 32 below it. The guide rod 33 is set to guide the vertical sliding of the first sliding sealing plate 14 and the second sliding sealing plate 15 and other components.
[0033] It should be noted that the sliding distance of the first sliding sealing plate 14 and the second sliding sealing plate 15 caused by the rotation of the screw 34 is equal to the distance between the first sliding sealing plate 14 and the second sliding sealing plate 15. When the monitoring probe 18 monitors the inside of the cabinet 10, the second sliding sealing plate 15 will engage with the first through hole 13 to form a seal on the cabinet 10. When the monitoring probe 18 monitors the outside of the cabinet 10, the first sliding sealing plate 14 will engage with the first through hole 13 to form a seal on the cabinet 10, thereby ensuring the overall sealing of the ring main unit and ensuring a stable working environment for the electronic components inside the cabinet 10.
[0034] Furthermore, such as Figure 3 As shown, an electronic lock 28 is installed on the inner wall of the cabinet door 11. Above the electronic lock 28, a limit ring 29 is installed on the inner wall of the cabinet body 10. The lock tongue of the electronic lock 28 is engaged with the limit ring 29. The electronic lock 28 is a combination lock. When multiple infrared human body sensors 27 detect that someone is approaching the ring network cabinet, the monitoring probe 18 and other components can be controlled to move to the top of the cabinet body 10 for monitoring. At the same time, the electronic lock 28 is controlled to lock the limit ring 29, thereby further locking the ring network cabinet. The electronic lock 28 can only be opened by entering the password on the outer end face of the cabinet door 11.
[0035] Example 2:
[0036] Based on Example 1, further examples are made, such as... Figure 4As shown, a rotating rod 24 is rotatably mounted between two support rods 20 below the arc-shaped scraper 21. A supplementary lighting plate 25 is mounted on the outer circular surface of the rotating rod 24. A second motor 26 is mounted on the side wall of the support rod 20 on one side of the rotating rod 24. The output end of the second motor 26 is fixedly connected to one end of the rotating rod 24. The second motor 26 is a servo motor, and its output shaft has a high-precision rotation adjustment function, which can adjust the rotation angle according to the needs. The output end of the second motor 26 drives the rotating rod 24 to rotate, thereby driving the supplementary lighting plate 25 to adjust the angle. When the monitoring probe 18 monitors the inside of the cabinet 10, it can perform supplementary lighting operation on the monitored area to improve the clarity of the monitoring probe 18 in the dark. When the monitoring probe 18 monitors the outside of the cabinet 10, it can provide warnings and supplementary lighting operation for people approaching.
[0037] Finally, it should be noted that the intelligent ring main unit monitoring device of this utility model needs to protect the various mechanical structures and related motion logic of the monitoring device in this solution. It is a corresponding device added on the basis of a mature ring main unit structure. Therefore, the ring main unit will not be described in detail, and the various sensors, detectors and driving components required by the various mechanical structures in actual operation will not be described in detail. However, for those skilled in the art, various control systems and electrical connection methods, including various electrical components and driving components, can be completed by conventional technical means. As long as the beneficial effect or the specific actions in the above work can be achieved, it can be implemented. This solution does not impose too many restrictions.
[0038] Furthermore, the sensors, exhaust fans, servo motors, cooling plates, etc. in this intelligent ring network cabinet monitoring device are all purchased from the market.
