A remote monitoring device for a power system and its monitoring method

Abstract

The present invention discloses a remote monitoring device for a power system and its monitoring method, including a monitor and a power cabinet. The monitor includes an image capture unit for capturing an image sequence, a sensor for generating a sensing signal, an output unit, and a processor. The processor is electrically connected to the image capture unit, the sensor, and the output unit. On the other side of the power cabinet, a power cover is fixedly connected. A power rod is rotatably connected through the upper wall of the power cover. The upper end of the power rod penetrates upward through the upper wall of the power cabinet and is fixedly connected with a wind cup. The advantages are as follows: Under normal working conditions, the rotation of the wind cup drives the impeller to rotate, thereby driving the liquid in the right pipe to flow upward through the bottom of the left pipe. Since the aperture of the through hole in the sliding column is small, the upward movement of the liquid will push the sliding column upward. Finally, the liquid returns to the right pipe to form a loop. The upward movement of the sliding column drives the baffle to move to a high position without blocking the air holes, ensuring a relatively fast heat exchange speed between the inside and outside of the power cabinet.

Description

Technical Field

[0001] The present invention relates to the technical field of power system monitoring, and particularly to a remote monitoring device for a power system and a monitoring method thereof. Background Art

[0002] With the increasing awareness of safety, safety monitoring applications have received more and more attention. Moreover, nowadays, as an indispensable part of daily life, the safety of the power system is particularly important. In the power system, as a connection node of the power system, the probability of failure of the power cabinet is higher than that of other places.

[0003] In addition, most of the power system monitoring in the prior art is solved by a pure electric control method. However, when a fault occurs in the power system, the monitoring energy of the pure electric control is often damaged synchronously. Therefore, it is particularly important to propose a remote monitoring device for a power system and a monitoring method thereof that reduce power control. Summary of the Invention

The processor is electrically connected to the image capture unit, the sensor, and the output unit. The processor is used to judge whether the sensing signal conforms to a predetermined working condition when receiving the sensing signal. The processor is used to judge that an event occurs when the sensing signal is abnormal. The processor is used to accumulate the occurrence times of the event within a first predetermined time and record the image sequence captured by the image capture unit within a second predetermined time when the event occurs. When the occurrence times are greater than or equal to a predetermined number, the processor controls the output unit to output a warning message and transmit it to an external server through a wireless signal.

[0006] A power device is arranged on an inner side wall of the power cabinet. A power cover is fixedly connected to the other side of the power cabinet. A power rod is rotatably connected through the upper wall of the power cover. The upper end of the power rod penetrates upward through the upper wall of the power cabinet and is fixedly connected to a wind cup.

A horizontal shaft is fixedly connected to the center of the worm gear. The horizontal shaft penetrates and is threadedly connected to the side wall of the power cover and is connected to a monitoring disk.

[0008] In the above-mentioned remote monitoring device for a power system, one end of the horizontal axis located inside the power cover is fixedly connected to a disc. The power cover is of a cylindrical structure, and its outer wall is rotatably connected to a rotating ring through a bearing. A fan blade is fixedly connected to the outer ring of the rotating ring.

The moving magnetic plate is slidably connected in the magnetic chute. A clamping groove is provided on the side wall of the power cover at the mating position of the rotating ring and the power cover. A plurality of permanent magnets are provided on the side wall of the disc. An electromagnet is embedded inside the disc. The permanent magnets are opposite to the fixed magnetic plates and the moving magnetic plate at the same level.

[0010] In the above-mentioned remote monitoring device for a power system, a number of air holes are equidistantly provided on the side wall of the power cabinet. A plate groove is provided at each air hole. A baffle is slidably connected in each plate groove. The plate groove is located above the corresponding air hole. A left pipe and a right pipe are provided on the side wall of the power cabinet. The left pipe is located on one side of the air hole. A synchronization block is slidably connected through the side wall of each plate groove.

[0011] In the above-mentioned remote monitoring device for a power system, each synchronization block is fixedly connected to a sliding column. Each sliding column is slidably connected inside the left pipe. A through hole is provided at the center of the sliding column. One end of the synchronization block away from the sliding column is fixedly connected to the baffle. The bottom of the left pipe and the right pipe are connected through a communicating pipe. The tops of the left pipe and the right pipe are jointly connected to a horizontal pipe. An impeller is provided inside the horizontal pipe. The axis of the impeller is fixedly connected to the power rod. The rotation of the impeller drives the liquid to flow inside the horizontal pipe.

[0012] In the above-mentioned remote monitoring device for a power system, one end of the horizontal axis located outside the power cover is rotatably connected to a cylindrical monitoring cover through a bearing. A fixed block is fixedly connected to the inner wall of the monitoring cover. An adjustment groove is provided at one end of the fixed block close to the horizontal axis. A connecting rod is slidably connected in the adjustment groove. One end of the connecting rod away from the fixed block is rotatably connected to a driven shaft through a bearing. The driven shaft is slidably connected through the side wall of the monitoring cover. Two second bevel gears are fixedly connected to the driven shaft. Two wire reels are fixedly connected to the driven shaft. A first bevel gear is fixedly connected to the horizontal axis.

[0013] In the above-mentioned remote monitoring device for a power system, a monitoring groove is formed on the monitoring disk, a monitor is slidably connected to the monitoring groove, a traction rope is fixedly connected to both ends of the monitor, the two traction ropes penetrate to both ends of the monitoring groove and are wound around a wire reel, a liquid sac is fixedly connected to each of the two ends of the monitoring groove, the two liquid sacs are respectively communicated with a telescopic sac through pipelines, and the two telescopic sacs are respectively fixedly connected to both ends of an adjustment groove.

[0014] A remote monitoring method for a power system includes the following steps:

[0015] S1. Generate a sensing signal;

[0016] S2. Determine whether the sensing signal exceeds a predetermined working condition;

[0017] S3. When the sensing signal is greater than the predetermined level, determine that an abnormal event has occurred;

[0018] S4. When an abnormal event occurs, accumulate the occurrence times of the event within a first predetermined time, and record the captured image sequence within a second predetermined time; and when the occurrence times are greater than or equal to a predetermined number, output a warning message and energize an electromagnet.

[0019] Compared with the existing technology, the advantages of the present invention are as follows:

[0020] 1. Under normal working conditions, the rotation of the wind cup drives the rotation of the impeller, thereby driving the liquid in the right pipe to flow upward through the bottom of the left pipe. Since the aperture of the through hole in the sliding column is small, the upward movement of the liquid will push the sliding column upward. Finally, the liquid returns to the right pipe to form a loop. The upward movement of the sliding column drives the baffle to move to a high position without blocking the air holes, ensuring a relatively fast heat exchange speed inside and outside the power cabinet;

[0021] 2. In the present invention, when the working condition is abnormal, the electromagnet works to generate a magnetic suction force on the moving magnetic plate. When the rotating ring rotates, the moving magnetic plate will slide and be stuck in the card slot, so that it cannot rotate. The fixed magnetic plate does not move, which will generate a large repulsive force on the permanent magnet, making the resistance it receives significantly increase, thereby reducing the rotation speed of the horizontal axis, reducing the liquid flow speed driven by the impeller, and the sliding column will gradually move downward under its own and the baffle's gravity, closing the air holes to prevent the air flow inside and outside the power cabinet, and avoiding the full combustion of oxygen inside the power cabinet due to sufficient oxygen.

Detailed implementation manners

[0028] The following embodiments are only for illustrative purposes and are not intended to limit the scope of the present invention.

[0029] Embodiment

[0030] Referring to Figures 1-5 , a remote monitoring device for a power system includes a monitor 24 and a power cabinet 1. The monitor 24 includes an image capturing unit for capturing an image sequence, a sensor for generating a sensing signal, an output unit, and a processor. The processor is electrically connected to the image capturing unit, the sensor, and the output unit; the processor is configured to determine whether the sensing signal conforms to a predetermined operating condition when receiving the sensing signal; the processor is configured to determine that an event has occurred when the sensing signal is abnormal; the processor is configured to accumulate the occurrence times of the event within a first predetermined time and record the image sequence captured by the image capturing unit within a second predetermined time when the event occurs; when the occurrence times are greater than or equal to a predetermined number, the processor controls the output unit to output a warning message and transmit it to an external server via a wireless signal;

[0031] A power device is provided on an inner side wall of the power cabinet 1; the other side of the power cabinet 1 is fixedly connected with a power cover 2. A power rod 3 is rotatably connected through the upper wall of the power cover 2. The upper end of the power rod 3 penetrates upward through the upper wall of the power cabinet 1 and is fixedly connected with a wind cup 4. The wind cup 4 rotates under the action of external wind force and inputs power into the power cover 2;

[0032] The part of the power rod 3 located inside the power cover 2 is set in a worm shape. The power rod 3 is engaged with a worm gear 6. A horizontal shaft 5 is fixedly connected to the center of the worm gear 6. The horizontal shaft 5 passes through and is threadedly connected to the side wall of the power cover 2 and is connected to a monitoring disk 22. The monitor 24 on the monitoring disk 22 monitors the electrical appliances in the power cabinet 1 in real time.

[0033] One end of the horizontal shaft 5 located inside the power cover 2 is fixedly connected to a disk 7. The power cover 2 is of a cylindrical structure and its outer wall is rotatably connected to a rotating ring 8 through a bearing. A fan blade 13 is fixedly connected to the outer ring of the rotating ring 8. The rotation of the fan blade 13 enables the air in the power cabinet 1 to exchange heat with the outside through the air holes 14, avoiding excessive temperature inside the power cabinet 1.

[0034] The rotating ring 8 is provided with a plurality of fixed magnetic plates 9 and one moving magnetic plate 10. The fixed magnetic plates 9 are fixedly connected inside the rotating ring 8. A magnetic sliding groove 11 is provided in the inner ring of the rotating ring 8 along its radial direction. The moving magnetic plate 10 is slidably connected in the magnetic sliding groove 11. A clamping groove 12 is provided in the side wall of the power cover 2 at the mating part of the rotating ring 8 and the power cover 2. A plurality of permanent magnets are provided on the side wall of the disk 7, and an electromagnet is embedded inside the disk 7. The permanent magnets are opposite to the fixed magnetic plates 9 and the moving magnetic plate 10 at the same level. Under normal working conditions, the electromagnet is in a power-off state. At this time, the permanent magnets generate magnetic repulsive forces with the fixed magnetic plates 9 and the moving magnetic plate 10, causing the moving magnetic plate 10 to be located at one end of the magnetic sliding groove 11 far from the disk 7.

[0035] A plurality of air holes 14 are equidistantly provided on the side wall of the power cabinet 1. A plate groove 15 is provided at each air hole 14. A baffle 16 is slidably connected in each plate groove 15. The plate groove 15 is located above the corresponding air hole 14. A left pipe 17 and a right pipe 18 are provided on the side wall of the power cabinet 1. The left pipe 17 is located on one side of the air hole 14. A synchronous block is slidably connected through the side wall of each plate groove 15. When the sliding column 19 moves in the left pipe 17, the baffle 16 moves synchronously with it.

[0036] Each synchronous block is fixedly connected to a sliding column 19. Each sliding column 19 is slidably connected in the left pipe 17. A through hole is provided at the center of the sliding column 19. One end of the synchronous block far from the sliding column 19 is fixedly connected to the baffle 16. The bottoms of the left pipe 17 and the right pipe 18 are connected through a communicating pipe. The tops of the left pipe 17 and the right pipe 18 are jointly connected to a horizontal pipe 20. An impeller 21 is provided in the horizontal pipe 20. The center of the impeller 21 is fixedly connected to the power rod 3. The rotation of the impeller 21 drives the liquid in the horizontal pipe 20 to flow. Under normal working conditions, the wind cup 4 rotates to drive the impeller 21 to rotate, thereby driving the liquid in the right pipe 18 to flow upward through the bottom of the left pipe 17. Since the aperture of the through hole in the sliding column 19 is small, the upward movement of the liquid will push the sliding column 19 upward. The liquid finally returns to the right pipe 18 to form a loop. The upward movement of the sliding column 19 drives the baffle 16 to move to a high position without blocking the air hole 17.

[0037] One end of the horizontal axis 5 located outside the power cover 2 is rotatably connected with a cylindrical monitoring cover 25 through a bearing. A fixed block 30 is fixedly connected to the inner wall of the monitoring cover 25. An adjustment groove is opened at one end of the fixed block 30 close to the horizontal axis 5. A connecting rod 31 is slidably connected in the adjustment groove. One end of the connecting rod 31 away from the fixed block 30 is rotatably connected with a driven shaft through a bearing. The driven shaft passes through and is slidably connected to the side wall of the monitoring cover 25. Two second bevel gears 27 are fixedly connected to the driven shaft. Two wire reels 28 are fixedly connected to the driven shaft. A first bevel gear 29 is fixedly connected to the horizontal axis 5. The two second bevel gears 27 can move along with the driven shaft. The movement of the driven shaft can make the two second bevel gears 27 engage with the first bevel gear 29 in sequence, so as to change the rotation direction of the driven shaft.

[0038] A monitoring groove 23 is opened on the monitoring disc 22. A monitor 24 is slidably connected to the monitoring groove 23. A traction rope is fixedly connected to both ends of the monitor 24. The two traction ropes penetrate to both ends of the monitoring groove 23 and are wound around the wire reels 28. A liquid sac 26 is fixedly connected to each of the two ends of the monitoring groove 23. The two liquid sacs 26 are respectively communicated with a telescopic sac through a pipeline. The two telescopic sacs are respectively fixedly connected to both ends of the adjustment groove. When the monitor 24 impacts one of the liquid sacs 26, the corresponding liquid sac 26 shrinks and squeezes the liquid therein into the telescopic sac. The telescopic sac elongates and pushes the connecting rod 31 to move, driving the first bevel gear 29 to engage with the other second bevel gear 27, changing the rotation direction of the driven shaft. When the rotation directions of the driven shafts are different, the winding directions of the two wire reels are opposite, so as to pull the monitor 24 to move in the reverse direction.

[0039] A remote monitoring method for a power system includes the following steps:

[0040] S1. Generate a sensing signal;

[0041] S2. Judge whether the sensing signal exceeds a predetermined working condition;

[0042] S3. When the sensing signal is greater than the predetermined level, judge that an abnormal event occurs;

[0043] S4. When an abnormal event occurs, accumulate the occurrence times of the event within a first predetermined time, and record the captured image sequence within a second predetermined time; and when the occurrence times are greater than or equal to a predetermined number of times, output a warning message and energize the electromagnet.

[0044] In the present invention, when the working condition is abnormal, the electromagnet works to generate a magnetic suction force on the moving magnetic plate 10. When the rotating ring 8 rotates, the moving magnetic plate 10 will slide and be stuck in the card slot 12, so that it cannot rotate. And the fixed magnetic plate 9 remains stationary, which will generate a large repulsive force on the permanent magnet, significantly increasing the resistance it receives. As a result, the rotational speed of the horizontal shaft 5 decreases, the impeller 21 drives the liquid flow speed to decrease, and the sliding column 19 will gradually move downward under the action of its own gravity and the gravity of the baffle 16, closing the air holes 14 to prevent the air flow inside and outside the power cabinet 1, and avoiding the full combustion of oxygen in the power cabinet 1 due to sufficient oxygen.

[0045] Although the terms such as power cabinet 1, power cover 2, power rod 3, wind cup 4, horizontal shaft 5, worm gear 6, disc 7, rotating ring 8, fixed magnetic plate 9, moving magnetic plate 10, magnetic chute 11, card slot 12, fan blade 13, air hole 14, plate groove 15, baffle 16, left pipe 17, right pipe 18, sliding column 19, horizontal pipe 20, impeller 21, monitoring disc 22, monitoring groove 23, monitor 24, monitoring cover 25, liquid sac 26, second bevel gear 27, wire reel 28, first bevel gear 29, fixed block 30, connecting rod 31 are used more frequently in this article, it does not exclude the possibility of using other terms. The use of these terms is only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
