Description

Technical Field

[0001] The invention relates to the technical field of automated cabinets, in particular to an automated cabinet for power dispatching which is conducive to heat dissipation. Background Art

[0002] The power dispatching automation cabinet is a common device in the power automation system. It is mainly used for remote measurement, remote adjustment and remote control of voltage, current, power factor, frequency and other parameters in power systems such as substations and switch stations. In the operation of the power system, the role of the power dispatching automation cabinet is very important. By real-time monitoring of the operating status of electrical equipment and the changes in various parameters, timely detection of problems and taking corresponding measures, the power system can be managed more finely to ensure the stable operation of the system.

[0003] Most of the existing power dispatching automation cabinets dissipate heat by opening heat dissipation holes on the cabinet body. The heat dissipation effect is poor and the heat inside the cabinet cannot be effectively removed, which easily leads to damage to some electrical components in the cabinet due to the inability to dissipate heat. Therefore, some power dispatching automation cabinets have undergone structural adjustments and added cooling fans in the cabinet. However, while the cooling fan draws external air for cooling, it also draws a large amount of dust into the cabinet. The dust accumulates in the cabinet for a long time, which not only affects the use of the electrical components in the cabinet, but also easily blocks the heat dissipation holes and reduces the heat dissipation efficiency.

The two sixth rotating seats 47 are each provided with a rotatable driving chain 34. The driving chain 34 connects the two first brushes 336 and the second brush 46 together. The stretching of the third electric cylinder 32 can simultaneously drive the two first brushes 336 and the second brush 46 to clean the dust on the air inlet 15 and the air outlet 18.

[0056] Working principle:

[0057] When in use, when the temperature sensor 14 detects that the temperature of the inner cavity of the cabinet 1 is higher than the set temperature, the second cooling fan 29 is started to draw in the outside air so that it enters the cabinet 1 through the air inlet 15 opened on the outer wall of the cabinet 1 to cool down the inside. The air guide plate 24 can guide the outside air, and the third electric cylinder 32 stretches to drive the second support plate 33 to move upward, and the first brush 336 also moves upward, pushing the drive chain 34 to move upward;

[0058] When the driving chain 34 moves upward, the second brush 46 and the other first brush 336 also move accordingly, so as to clean the first filter screen 171 and the second filter screen 172 and the second filter plate 41 of the air inlet 15 on both sides, thereby preventing dust from accumulating and clogging for a long time and affecting the heat dissipation effect in the later stage, and also improving the overall filtering effect of the cabinet 1;

[0059] When the temperature sensor 14 detects that the temperature continues to rise, the second cooling fan 29 cannot effectively dissipate heat, and the first electric cylinder 25 is started. The first electric cylinder 25 stretches to drive the first connecting rod 27 to rotate, and the air guide plate 24 moves toward the inner wall of the cabinet 1. The air guide plate 24 squeezes the proximity sensor 231, and the proximity sensor 231 also sends a signal. At the same time, the first cooling fan 22 is started. The first cooling fan 22 and the second cooling fan 29 operate at the same time. The adjustable air guide plate 24 can avoid the phenomenon that the two wind directions collide and cause the cooling effect to be weakened. When the first brush 336 moves to the upper end or the lower end of the air inlet 15, the third electric cylinder 32 is closed;

[0060] The second electric cylinder 178 is started, and the second electric cylinder 178 is stretched to drive the second connecting rod 17 to rotate, and the first filter screen 171 and the second filter screen 172 also rotate accordingly, which can increase the air intake area. At the same time, the rotation of the second connecting rod 17 drives the fourth connecting rod 44 to rotate, and the second telescopic column 434 also rotates accordingly, driving the two third filter plates 43 to slide. At this time, the second vent 432 in the third filter plate 43 is located below the first vent 421 in the second filter plate 41, and the second vent 432 is connected to the first vent 421, so that the air outlet area is increased, and the heat dissipation effect is improved;

[0061] The rotation of the second filter 172 drives the first rotating block 174 to rotate. When the first brush 336 is located at the upper end of the air inlet 15, the first rotating block 174 above the second filter 172 rotates and squeezes the third support plate 337. When the first brush 336 is located at the lower end of the air inlet 15, the first rotating block 174 below the second filter 172 rotates and squeezes the fourth support plate 338, both of which drive the first brush 336 to move away from the cabinet 1 to prevent the first brush 336 from interfering with the rotation of the first filter 171 and the second filter 172 until the temperature sensor 14 detects that the temperature of the inner cavity of the cabinet 1 drops to the set temperature and stops.

[0062] After the cabinet 1 has been used for a period of time, the staff opens the outer door of the heat dissipation box 31 for inspection and maintenance. The staff pulls the pull rod 323, the second wedge block 324 is separated from the first wedge block 332, and the second support plate 33 can be unlocked from the second fixed block 322. The staff can manually move the second support plate 33 to clean the first filter screen 171, the second filter screen 172 and the second filter plate 41. After the inspection is completed, the third fixed block 331 can be inserted into the second fixed block 322.
