Power supply switching device for a computing center

Abstract

This invention discloses a power switching device for intelligent computing centers, belonging to the field of power switching. The device includes a rotating plate rotatably disposed inside a protective housing. The rotating plate covers the area of ​​a movable plate. When the two rotating plates are closed, dust is prevented from directly falling onto the surface of the movable plate. When the two rotating plates rotate towards each other and separate, the movable plate is directly exposed, allowing for cleaning of dust on its surface without moving the movable plate and preventing damage to its power switching components. Simultaneously, a rotating eccentric wheel is provided, which drives the movable plate to slide back and forth inside the protective housing. A dust-cleaning fan is also installed inside the protective housing. When the movable plate slides, it drives the dust-cleaning fan to rotate, moving dust from the surface of the movable plate towards the fan and discharging it through a dust-cleaning groove, thus cleaning the surface of the movable plate. The rotating plate and dust-cleaning fan provide two methods for cleaning the surface of the movable plate, which can be selected according to the usage conditions.

In a further embodiment, the protective shell 2 is internally threaded with a push rod 65, the end of which contacts the drive wheel 54; rotating the push rod 65 causes the adjusting tooth 62 to engage in the gear groove 63, at which time the synchronizing rod 51 rotates, which can synchronously cause the drive wheel 54 to rotate, the movable plate 1 slides up and down and the two rotating plates 31 separate. In some specific implementations, a motor 61 is fixedly connected inside the protective shell 2, and a central rotating rod 67 is fixedly connected to the end of the output shaft of the motor 61; the central rotating rod 67 is fixedly connected to the eccentric wheel 32; and the motor 61 is electrically connected to an external power source.

The rotation of the central rotating rod 67 drives the eccentric wheel 32 to rotate, and then the movable plate 1 slides back and forth. The rotation of the central rotating rod 67 causes the conical wheel 66 to rotate. Through the ring array and the synchronous rod 51, the dust cleaning fan 35 is made to rotate, and then the dust inside the movable plate 1 is discharged from the dust cleaning groove 34 under the action of the dust cleaning fan 35. When deep cleaning of the movable plate 1 is required, the push rod 65 can be rotated into the protective shell 2 to cause the adjusting gear 62 to engage with the gear groove 63. At this time, the rotation of the synchronizing rod 51 will cause the drive wheel 54 to rotate synchronously, thereby causing the two rotating plates 31 to rotate in opposite directions, causing the protective plate to be directly exposed. Then, the motor 61 can be turned off, and dust can be cleaned manually as needed.
