FIELD OF THE INVENTION

The present invention relates generally to a dust collection system and more specifically to a dust collection system for electrical equipment.


BACKGROUND OF THE INVENTION

As anyone who performs a lot of mechanical work will attest, nothing beats having the proper tool for a job. The proper tool can save time, save money, produce a higher quality job, reduce damage to equipment, and provide for the increased safety of the worker. Each field of mechanical work has its own type of specialty tools, each performing a specialized task.


One field where there has been a need for such a specialized tool is when removing dust from inside of electrical equipment such as switchgear or motor control centers to ensure proper and safe operation. Many workers resort to the use of compressed air as it is very effective in lifting the dust from every crack and crevice. Unfortunately, such action creates a dust cloud that can be explosive in nature. It also simply allows the dust to settle back down elsewhere. Vacuuming is often recommended as it removes the dust, but it is not effective at removing all of the dust. Accordingly, there exists a need for a means by all dust can be removed from electrical equipment in a manner which addresses the current shortcomings. The development of the electrical equipment dust collection system fulfills this need.


SUMMARY OF THE INVENTION

To achieve the above and other objectives, the present invention provides for an electrical equipment dust collection system which has a cover panel adapted to cover an open side of an equipment enclosure and a vacuum port having a vacuum fitting and a vacuum flare. The vacuum port is adapted to removably couple to a vacuum hose of a vacuum cleaner such that the vacuum cleaner suctions dust out of the equipment enclosure and the vacuum port is an interface for coupling the vacuum hose of the vacuum cleaner. The electrical equipment dust collection system also has a blow gun having an air hose fitting, a boot, and an air wand. The blow gun is adapted to removably couple to a source of compressed air and the blow gun directs a stream of air at a piece of electrical equipment such that the dust is dislodged from the piece of electrical equipment.


The air hose fitting is an attachment point for coupling an air hose connected to the source of compressed air, and the air wand is a tube projecting from the air hose fitting on the rear of the cover panel. The electrical equipment dust collection system also has handle including a grasping point for holding the cover panel in place against the equipment enclosure and a light strip illuminating the interior of the equipment enclosure such that the dust is made easier to view. The light strip is coupled to the rear side of the cover panel. The light strip includes a plurality of lights, an on/off control, and a battery.


The open side of the equipment enclosure may result from a door of the equipment enclosure being opened or may result from the door of the equipment enclosure being removed. The cover panel may be a rigid, non-conductive plate operable to cover the open side of the equipment enclosure. The cover panel may be rectangular-shaped. The vacuum fitting may be located at a center of the vacuum flare. The vacuum fitting may provide a friction fit coupling to the vacuum hose. The vacuum fitting may include a 90-degree angle within a plane that is parallel to the cover panel such that the vacuum hose hangs down while the piece of electrical equipment dust collection system is in place on the equipment enclosure. The vacuum fitting may rotate such that the electrical equipment dust collection system is used in a plurality of orientations.


The vacuum flare may be a projection of the cover panel away from the equipment enclosure. The vacuum flare may be a dome or a frustum of a cone. The vacuum flare may be transparent to provide a view of an interior of the equipment enclosure. The boot may be a semi-rigid sheath that holds the air hose fitting above the cover panel or a corrugated cone.
