Device for restoring integrity of ice road in ice pool

Abstract

The invention discloses a device for restoring the integrity of an ice road in an ice pool, and belongs to the technical field of ship testing. The device is composed of a sub-trailer, track modules,a frame module, an electromagnetic control module, and an ice cover fixing device. The two track modules are mounted at a lower rectangular frame in parallel, and are connected by a connecting plate.A cage frame is mounted on the connecting plate. The two track modules are mounted at the two sides of the cage frame. The sliding blocks of the track modules are separately connected with L-shaped connecting plates. An attracted-disk electromagnet is mounted at the lower end of the L-shaped connecting plate. Non-slip cloths are wound on long wood plates. The transverse wood plates are connected with the two long wood plates by U-shaped buckles. The iron plates are fixed on the long wood plates. The device adopts a modular assembly, so that the operation speed is greatly improved; the mountedposition is adjusted timely and accurately; the damage to an ice layer is reduced; and the release and the salvage of the ice cover fixing device are easy. Therefore, the test efficiency is improved;the test cost is reduced; and the application range is extended.

Description

technical field [0001] The invention belongs to the technical field of ship testing, and in particular relates to a device for restoring the integrity of ice passages in ice water pools. Background technique [0002] Countries in the world that carry out more ice engineering tests include Russia, Finland, Canada, the United States, South Korea and other countries. Ice engineering experiments have been carried out in the ice pool laboratory for decades. The initial ice engineering experiment started from the research of icebreakers. The world's first cryogenic ice pool laboratory was built in the former Soviet Union in 1955, and the first Two ice pools were built in Finland in 1969. The initial development of the ice engineering laboratory is very slow. Usually, the scale is small and the level is low. There are few test contents that can be carried out. The main focus is on the navigation performance of ships in ice areas. The test methods and model ice production methods a...

Problems solved by technology

However, when the ship model carries out the ice-breaking test, after a channel is opened, one side of the remaining flat ice is connected to the pool wall, and the other side is not restricted by the pool wall or other ice layers. Therefore, when carrying out the ice-breaking navigation test of the ship model When the ice layer is easy to slide
