Door Threshold Vacuum

An apparatus for automatically cleaning dirt and debris from a pedestrian's footwear. The apparatus can be an integral portion of the entryway door's threshold or else can be made portable. The pedestrian steps upon a removable tray and activates a vacuum source. The vacuum source pulls the dirt and debris from the pedestrian's footwear through a multitude of openings in the removable tray. The dirt and debris is captured within the tray (large particles) and debris collection container (smaller particles) for later disposal. The apparatus cleans the welts and also provides a means for drying wet footwear. The apparatus can be either AC or DC powered and can be automated to only operate when a pedestrian is standing upon the tray, can operate continuously, or can be manually switched on and off.

Threshold-free hydraulic weather-tight hinged door for ship

The invention relates to a threshold-free hydraulic weather-tight hinged door for a ship. The threshold-free hydraulic weather-tight hinged door comprises a door frame, a door leaf, a lifting hinge device, a sealing rubber strip, an oil cylinder and the like. In order to meet the requirements of large equipment, cargoes, vehicles and in-out cabins on a ship, a hinged door frame is required to be threshold-free, and a conventional hydraulic weather-tight hinged door cannot meet the requirements. The door frame is of a threshold-free structure, and a door body sealing strip needs to meet the sealing requirement on a door frame sealing face and a bottom deck sealing face. The hinge is a lifting hinge. Before the door leaf is opened or closed, the door leaf is lifted to a certain height by the lifting oil cylinder through the lifting hinge, so that collision or friction caused by contact between a sealing strip at the bottom of the door leaf and a ship body deck (including a guide rail and other structures arranged on the ship body deck) in the opening and closing process is avoided; after the door leaf is opened, the hydraulic control one-way valve arranged on the door opening oil cylinder can fix the door leaf, and the door body is prevented from swinging due to shaking of the ship body. The hinge door can meet the weather tight requirement, and the flushing test pressure reaches 0.2 MPa.
