Polar ship louver and de-icing method thereof

Abstract

The invention discloses a polar ship louver and a de-icing method thereof. The polar ship louver comprises a window frame and louver blades parallelly arranged in the window frame, a detecting mechanism used for detecting the icing state and a heating mechanism used for melting ice are arranged in the window frame, and the detecting mechanism and the heating mechanism are all electrically connected with a controller. By arranging the detecting mechanism, the heating mechanism can be started for melting the ice only during icing of the louver, energy consumption is reduced, the economical efficiency of a ship is improved, detecting and de-icing are automatically controlled without manual operation, the operation difficulty is lowered, and operation safety is improved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a polar ship shutter and a deicing method thereof. Background technique [0002] For ships navigating in polar regions, due to the extremely low ambient temperature in polar regions, the shutters of the ship's engine room (the entrance through which the outside air enters the engine room) are extremely prone to freezing. If the louvers are blocked due to too thick ice, the outside air cannot enter the engine room, which will cause the host equipment in the engine room to not work normally due to lack of oxygen, and then make the ship unable to operate normally. [0003] At present, electric heating wires are generally installed on the blinds for deicing, or the crew uses a mallet to tap the ice on the blinds at regular intervals to achieve the purpose of deicing. Existing deicing methods have the following defects: 1. Electric heating wires are used for heating. Generally, the ele...

Problems solved by technology

Existing deicing methods have the following defects: 1. Electric heating wires are used for heating. Generally, the electric heating wires on the shutters are always opened to keep the shutters at a high temperature to prevent freezing. Turn on the electric heating wire, so it will consume a lot of electric energy on the ship and increase the load on the ship, so that the generator capacity of the ship needs to choose a model with a larger specification (higher power) when designing, which increases the construction cost of the ship, and in the later operation. It will consume more fuel and reduce the economy of the ship; 2. Manual deicing with a mallet will make the crew go to the position of the outdoor shutters to deal with it. Due to the harsh outdoor environment, low temperature, and slippery deck, it will increase The danger of the crew working outdoors also increases the work intensity
