DEVICE FOR PROTECTING FLOATING DOCK FROM BROKEN ICE Russian patent published in 2023 - IPC B63C1/02 E02B15/02 

FIELD: shipbuilding; ship repair.

SUBSTANCE: devices for protecting a floating dock from broken ice. A device for protecting a floating dock from broken ice contains a source of compressed air and a perforated pipeline connected to it by a metal pipe, mounted on brackets and mounted along the guard contour below the level of the dock well deck. The perforated pipeline consists of perforated pipes with a diameter of 140 mm connected to each other by flanged connections with perforation holes with a diameter of 10 mm, located in a checkerboard pattern. The first row of holes is made at an angle of 90° up from the well deck, and the second row of holes is made with a 50 mm offset from the first row of holes away from the well deck. On the opposite side to the holes with a diameter of 10 mm in each pipe there are holes with a diameter of 25 mm with the ability to drain water when the floating dock surfaces. Inside each pipe with a diameter of 140 mm, an air supply pipe with a diameter of 57 mm is installed, secured by welding seams, along the entire length of which there are holes with a diameter of 10 mm, located at a distance of 100 mm relative to each other and looking down at an angle of 90° in relation to the well deck of the floating dock.

EFFECT: increasing the efficiency of removing ice from the deck of a floating dock.
