Description

A power supply device for stage equipment

Technical Field

The utility model relates to the technical field of power supply equipment, in particular to a power supply device for stage equipment.

Background Art

Existing stage equipment involves different fields such as lighting, sound, machinery, scenes, and videos. All kinds of equipment require power supply equipment to operate normally.

A Chinese patent with application announcement number CN212751886U discloses a UPS power supply device. In this patent, through the coordination of the fan, the dust filter, the first air outlet and the second air outlet, the fan is used to work at the bottom of the UPS power supply body, so that the external air passes through the dust filter, the first air outlet and the second air outlet in sequence, thereby realizing the circulation of air inside the shell, effectively improving the fluidity of the air in the UPS power supply body, enhancing the heat dissipation effect of the UPS power supply body, and improving the service life of the UPS power supply body.

When using the above patent, we found that the dust filter in the device is not convenient to disassemble and clean. Long-term use will cause the dust filter to accumulate a lot of dust, which greatly affects the air circulation in the control shell and leads to poor heat dissipation in the shell. Therefore, we proposed a power supply device for stage equipment.
