Description
Technical Field
The utility model relates to the field of ship deicing, in particular to an electromagnetic induction deicing device for a deck deicing vehicle.
Background
In severe winter and high-latitude sea areas, a large amount of ice coating is easily formed on the surface of the ship, the sailing speed and sailing safety of the ship are affected if serious, meanwhile, the friction coefficient of the deck can be reduced when the deck is frozen, the safety of operations such as taking off, landing and transferring of the aircraft on the ship is threatened, the work of crews is not facilitated, and the risk of slipping is caused. Deicing and snow removal of the deck is a very important task.
The method of deicing includes active deicing and passive deicing.
Active deicing is a treatment mode for dealing with icing conditions by arranging structures in advance, and mainly comprises two main types: firstly, adding special materials into the deck coating to reduce icing or icing fastness; secondly, coils and other accessories are pre-buried in the ship body in advance, and electric pulse or electric repulsion is utilized to remove ice, and electromagnetic repulsion force is utilized to remove ice. The method needs to consider the scheme when the ship is designed and manufactured, the complexity of the ship structure can be increased, and the flexibility is low.
Passive deicing is largely divided into four major categories: firstly, a mechanical method is adopted, and ice is removed by a mechanical device in modes of shoveling, knocking and strong vibration; secondly, a chemical method is adopted, ice melting and snow melting agents are thrown on an ice layer, and ice is removed or the ice degree is reduced by lowering the freezing point temperature; thirdly, an ultrasonic method is adopted, and the ice layer is crushed and peeled off through ultrasonic vibration; and fourthly, heating to melt the ice layer by means of electromagnetic waves, electric heating, infrared rays, steam, high-temperature gas, laser and the like.
The mechanical method has the defects of incomplete removal and easy damage to the coating and the steel matrix; the chemical method has the defects of slow reaction time and great influence on the environment; the ultrasonic method has the defect that the ultrasonic method is only suitable for common pavement, and when the ultrasonic method is applied to ships, because metal is an excellent conductor of sound, the ultrasonic can be conducted to other cabins of the ships, and damage is caused to other equipment. Only the heating method is a deicing method suitable for ships.
The device (CN 201110083434) for removing the wrappage on the surface of steel and the device (CN 201220001405) for removing the coating on the surface of metal by electromagnetic induction are used for generating vortex current on the surface of metal by utilizing the electromagnetic induction principle to form local high temperature so as to remove the wrappage and the coating on the surface of metal. However, the deck coating of the ship is very important and cannot be damaged by deicing equipment, so that the technology of the two patents cannot be directly applied to the field of ship deicing.
